Safety Fish Way
A safe fish guide path structure includes a horizontal tube having an intake and exhaust valve for controlling levels of air having lower viscosity than water. The horizontal tube is equipped with a transparent window at both sides about the intake and exhaust valve. The horizontal tube is installed at a weir or a bank. An inclined tube extends horizontally from both sides of the horizontal tube. An extended tube extends horizontally from an end portion of the inclined tube. An inlet tube extends from an end portion of the extended tube toward an upper side, while communicating with the extended tube, with water flowing through the inlet tube. A cover has an insertion groove at one side into which the extended tube is inserted, and a cut-away groove at the other side for water to flow through the cutaway groove.
The present invention relates to a safety fishway, and in particular to a safe fish guide path structure which enables a safe movement of a fish by stopping the flow of water in a fish path when water flows a high speed in the event of flood, and provides a safe shelter as the water in the path increases during the dry season in which the bottom of a river is exposed, and the present invention rakes it possible to enhance a water quality as the water at the bottom of the river is continuously exchanged with new water and is well applied to a small dimension river as compared with a conventional intermittent discharge of water stopping the flow of water until the water level reaches a certain level.
BACKGROUND ARTA weir or a bank is generally installed at a river or a stream in order to efficiently use stored water for an agricultural purpose or an industrial purpose.
The conventional weir or bank used to stop various fishes living an upstream or downstream of a river from moving between the upstream and the downstream while interrupting the communications of deep water at the bottom of the river or the stream, thus increasing the contamination of the deep water. In the event of the dry season, the ecosystem of aquatic animals and plants is destroyed.
In order to overcome the above problems, various kinds of fish guide path structures are installed at a weir or a bank for allowing fishes to move to other places.
The above-described conventional fish guide path structures still have problems. The fishes with weak swimming abilities cannot be easily move to another place, and the deep water residing at a deep portion of a river or a stream does not help improve the water quality, and the structure is made too complicated, which results in various problems.
DISCLOSURE OF THE INVENTIONAccordingly, it is an object of the present invention to provide a safe fish guide path structure which is basically designed to overcome the problems encountered in the conventional art, and makes it possible to enable a safe and stable movement of fishes with weak swimming abilities while significantly improving the water quality in the river car the stream.
To achieve the above object, there is provided a safe fish guide path structure which comprises:
a horizontal tube which has an intake and exhaust valve for the multiple purposes performing an exhaust function for a water level decrease and increase of the air in the tube for the sake of a water level control of the horizontal tube serving to determine the amount of water to be exhausted and an interruption function for maintaining a constant water level, with the horizontal tube being equipped with a light transparent window at both sides about the intake and exhaust valve, with the horizontal tube generally being installed at a weir or a bank; an inclined tube which is extended from both sides of the horizontal tube in a horizontal direction while communicating with the horizontal tube; an extended tube which is extended from an end portion of the inclined tube in a horizontal direction while communicating with the inclined tube; an inlet tube which is extended from an end portion of the extended tube toward an upper side, while communicating with the extended tube, with the water of the river or the stream flowing through the inlet tube; and a cover which has an insertion groove at one side into which the extended tube is inserted, and a cut-away groove at the other side for the water of the aver or the stream to flow through the cutaway groove.
Here, the horizontal tube has a through hole at its bottom surface, and a chamber is formed at a lower side of the through hole for fishes to swim.
In addition, a transparency window is provided at a front surface of the horizontal tube and a front surface of the chamber, respectively, for checking out the level of the water stored in the horizontal tube and the chamber.
ADVANTAGEOUS EFFECTSThe safe fish guide path structure according to the present invention has advantages in that fishes can rove to another places in sage and provides fishes with a safe shelter while gathering lots of fishes in such a way to stop the flow of the water in the interior of the fish guide path at the time of flood, eddy current or rapid stream.
In addition, even when the fish guide path inlets are fully exposed to the air during the dry season or due to the dried river or stream, since the water does not flow outside the fish guide path, a safe shelter can be provided to the fishes.
In the event that the bottom surface of the inlet tube is constructed to come into contact with the bottom of the river or the stream at usual time, since the deep water of the river or the stream is continuously discharged, the water quality of the water of the river or the stream can be significantly improved.
It is possible to easily control the level of the water of the horizontal tube which serves to the control of the flow amount of water depending on the increase and decrease of the volume of light air instead of using the water having a relatively higher viscosity by controlling the intake and exhaust valve.
Since a light transparency window is installed at an upper surface of the horizontal tube, sunshine or moonshine can reach the inner side of the safe fish guide path, the movements of fishes can be efficiently conducted by helping the fishes to easily find ways.
A light transparency window is installed at the front surfaces of the horizontal tube and the chamber, respectively, it is possible to easily check out the level of the water in the interior of the safe fish guide path, and the safe swimming of the fishes can be obtained in such a way to control the level of water by means of the intake and exhaust valve
In addition, the safe fish guide path structure of the present invention works in perfect even when a water gate is not additionally installed at the weir or the bank, thus saving the water gate installation cost.
The present invention will become better understood with reference to the accompanying drawings which are given only by way of illustration and thus are not limitative of the present invention, wherein;
The preferred embodiments of the present invention will be described with reference to the accompanying drawings.
The safe fish guide path structure according to the present invention comprises a horizontal tube 10 installed at an upper side of a weir or a band D, an inclined tube 20 communicating with the horizontal tube 10, an extended tube 30 communicating with the inclined tube 20, an inlet tube 40 communicating with the extended tube 30, and a cover 50 installed at an upper side of the inlet tube 40.
The horizontal tube 10 is installed at an upper side oaf a weir or a bank generally installed at a river or a stream, and is formed in a tube shape having a space in its inner side which becomes a water flow path.
The horizontal tube 10 has an intake and exhaust valve 11 allowing the amount of the air in the inner space to be introduced or discharged, thus controlling the level of water in the interior.
In more details, the total volume of water and air which have different natures maintains constant, and the inlet tube in the horizontal state is always under the atmospheric pressure. The intake and exhaust valve 11 provided for a relative water level adjusting purpose with the aid of the volume increase and decrease of the air which is lighter than other materials is connected with an air pump (not shown). When the air is removed from the interior of the horizontal tube 10 as the air pump gets started, the water is pumped from the river or the stream through the inlet tube 40, the extended tube 30 and the inclined tube 20 with the aid of the atmospheric pressure, thus filling the water into the interior of the safe fish guide path structure. On the contrary, when it is needed to remove the water from the interior of the safe fish guide structure, the water can be fast discharged from the interior of the safe fish guide path structure as the intake and exhaust valve is opened.
A light transparency window 12 is installed at the upper surface of the horizontal tube 10, in more detail, at both sides about the intake and exhaust valve 11.
It is preferred that the light transparency window 12 is made from a transparent material so that light can penetrate into the interior of the safe fish guide path structure, thus helping the fishes to swim in safe. The light transparency window 12 might be manufactured in an integrated form at the horizontal tube 10. As shown in
The horizontal tube 10 is formed in such a way to form a through hole 13 at the bottom surface, and a chamber 14 is formed at a lower side of the through hole 13.
The chamber 14 is a kind of the pool which receives the water raised up to the horizontal tube 10 as water is inputted into the interior of the safe fish guide path structure and stores the water. The chamber 14 is basically directed to helping provide the fishes with a shelter or a swimming place by filling water for the fishes to move even at the time flow speed is almost zero. As shown in
Meanwhile the see through window 15 is installed a front surface of the horizontal tube 10 and at a front surface of the chamber 14, respectively. The see through window 15 is preferably made from a transparent material so that the inner situations of the safe fish guide path structure can be seen from the outside. The water level of the interior of the safe fish guide path structure can be checked out through the see through window 15 or a water level detection rod might be installed at a certain portion where is needed when determining the inlets of the water into the interior of the safe fish guide path structure. The intake and exhaust pump can be designed or programmed to get automatically started at a set water level by means of a selector switch formed of an electric circuit.
The inclined tube 20 is extended from both ends of the horizontal tube 10 toward a lower side along an outer side surface of the weir or the bank, while communicating with the horizontal tube 10. The upper side of the inclined tube 20 is connected with the horizontal tube 10, and its lower side is positioned under the water surface of the river or the stream.
As shown in
The extended tube 30 is extended in a horizontal direction from the end portion of the inclined tube 20, while communicating with the inclined tube 20. So, the water inputted into the interior of the safe fish guide path structure through the inlet tube 40 can be inputted into the chamber 14 through the inclined tube 20 and the horizontal tube 10.
The inlet tube 40 is extended from the end portion of the extended tube 30 toward the upper side, while communicating with the extended tube 30. The inlet tube 40 is configured with its lower end portion being connected with the extended tube 30, with its upper end portion being configured to receive the water from the river or the stream.
The cover 50 is installed at the upper side of the inlet tube 40, with the width of the cover 50 being larger than the width of the inlet tube 40, and an insertion groove 51 is formed at one side surface, and the cut-away groove 52 is formed at the other side surface.
The insertion groove 51 is formed at a surface of the inlet tube 40 in the direction of the inclined tube 50, with an extended tube 30 being inserted into the insertion groove 51.
The cut-away groove 52 is formed at a surface formed at an angle of 90° with respect to the surface where the cut-away groove 52 is formed, and even when the cover 50 is installed at an upper side of the inlet tube 40, the water of the river or the stream can be inputted into the inlet tube 40 through the cut-away groove 52.
