Catch basin apparatus and method of use for the same
Apparatus for optimizing fluid flow while maximizing selective filtration of select debris and detritus functions as catch basin in conjunction with conventional sewers. Proximate to a curb inlet a diverter is located, and at least one sieve-member or element is disposed within the catch basin defining a primary and supplemental space for collecting solid materials, in combination with a drain access aperture allowing for ingress and egress to the supplemental space from the primary space to preclude blockage by facilitating access to the catch basin drain.
The present disclosure generally relates to novel catch basin constructions used in a sewer-type of apparatus which cost effectively make cleaning of the same easier, while being disposed simply without adding cost or time constraints.
The present disclosure further relates to catch basin improvements allowing for ongoing flow while selectively screening undesired elements from transmission to a drain.
BACKGROUND OF THE DISCLOSUREFiltration systems have been known throughout history for blocking ingress and egress selectively. Sewer systems and their related drains are a product of modern society, often having a need to be disposed within, for example, city streets in a metropolitan area. Combinations of these two usually distinct types of systems have yet to adequately address the issues managed by way of the present disclosure.
SUMMARYThe present disclosure works in conjunction with conventional drainage systems, for example, sewers which drain from the street. While it is known for drainage systems to work in conjunction with such street based systems, a fluid drainage system according to the instant disclosure uses novel mechanisms to handle any number of types of detritus without compromise to the flow-rate in ways not available prior to the advent of the instant teachings.
For example, by using the combination of at least one diverter and a sieve-member or element to divide a primary and at least a secondary collection area, the present disclosure overcomes the longstanding need to be able to get between, behind under or in back of the sieve-member or element and remove debris and detritus by way of a specialized aperture permitting ingress and egress.
The present disclosure manages the issue of having a continuous flow-path while being able to stem the flow of large pieces of debris, and being able to render those pieces which may become lodged readily removable. This is done in straight-forward fashion, enabling those charged with removing potentially clogging pieces of debris to have ready access to the area proximate to the drain which is at the bottom of the system.
Likewise, those skilled in the art shall understand that such improved catch basin technology overcomes the longstanding issues associated with spaces too small for workers to reach into to remove pieces of debris which become difficultly lodged. An additional aspect of the present disclosure is that it does not require further attachments, assemblies or supplemental pieces at the ingress, or for example, at the “curb” in a conventional city-type of sewer inlet. This feature is useful and enhances industrial efficiency.
According to the teachings of the instant disclosure, the efficiency of a conventional sewer system is further improved in that the enhancements to the catch basis render the system such that it does not need to be manually monitored or emptied with as high a degree of frequency. Owing to the simple mechanical aspects of functionality of the instant disclosure the involved materials can be both strong and robust in addition to being acquired without tremendous capital outlay.
Further, since many conventional, for example, metropolitan sewer systems, have many different locations needing to be improved, ready installation capacity, ease-of-use and transport make the teachings of the present disclosure attractive to users. It is also known to artisans how the solution offered by the instant teachings can have a “universal” aspect, if it functions in conjunction with or is readily adaptable to many different related types of systems.
Finally, owing to the modularity of the components according to the instant teachings plethoric combinations and subcombinations are available. For example, for use with conventional metropolitan sewer systems those having a modicum of skill shall understand that at least one diverter is easily curb-mounted with most existing systems, as is a sieve member or element combination. Being modular provides for easy and facile transport, shipping, storage and related conveniences.
BRIEF DESCRIPTION OF THE DRAWINGSThe present disclosure will be more clearly understood by reference to this specification in view of the accompanying drawings, in which:
Referring to the drawings,
And,
In
Although the apparatus can be adapted to accommodate catch basins with a different number of inner walls, each catch basin shown in the accompanying figures has four inner walls 17. The apparatus is shown installed in each of those catch basins by using angle-iron supports 18 with support bolts 19 passing through bolt holes 20 in a flange of the support 18 and into anchors 21 that have been placed in three of the inner walls 17 if each catch basin. (It should be understood that, although the support bolts 19 and anchors 21 are shown only in
Filter sheets 22 can then rest upon the supports (or, may be secured by any conventional means such as screwing the filter sheets 22 into the supports 18), with the plane of each filter sheet 22 located at a predetermined appropriate level above the floor 3 and oriented substantially parallel to the part of the floor 3 that is directly beneath the filter sheet 22. The appropriate level can provide at least enough clearance to permit a sufficient volume of fluid to flow along the floor 3 into the drain opening 4 to match the capacity of the drain opening 4. The capacity of the drain opening 4 is limited by such things as its size and the characteristics of the drain pipe 23 being used. The appropriate level also can be based on other criteria as desired by the user. Such other criteria may include factoring in the volume and quantity of trash that is likely to overflow and pass with the fluid into the space between the floor 3 and the one or more filter sheets 22. Of course, any conventional means may be used for supporting and securing the filter sheets 22 in their positions.

As seen in
The top-inlet filter 8, as shown in
Like the curb-inlet diverter 26, the top-inlet diverter 35 works to divert incoming trash away from the overflow area 28 to the filter side of the overflow wall 25. Also, the top-inlet diverter 35 of one embodiment is made using the same material, with apertures, as is used for making the filter sheets 22, so that the filtering process begins as the entering fluid and trash impact the top-inlet diverter 35. (The same preference for use of material with apertures applies to the overflow wall and the diverter in other embodiments. For example, this preference is discussed and applied above with respect to the left-drain filter 1, shown in
As shown in
The supports 18, filter sheets 22, the other parts of the apparatus, and the means for connecting them together and securing them to the inner walls 17 may be made of hot dipped galvanized steel, although they can be made of any other conventional material that is strong and durable in the presence of the fluids reasonably expected to pass through the catch basin in which they are installed, with due consideration to the potential for corrosion and/or electrolytes particularly when using more than one type of metal in the construction of the apparatus. Such other conventional materials include stainless steel, aluminum, plastics, carbon fibers, and composites. The means for connecting the parts of the apparatus to one another or to the catch basin can be any conventional connecting means such as, without limitation, bolts, screws, welds, clamps, and/or adhesives.
The supports 18 shown herein as angle irons may be installed with the vertical side of the angle iron pointed up or down. The accompanying figures show the vertical side point up on the supports 18 used to support the filter sheets 22. Nevertheless, an alternative embodiment with the vertical side of the supports 18 pointing down would appear helpful in order to cause less interference between the support bolts 19 and the filter sheets 22. (A sample of this alternative orientation of the vertical side of the supports is found in the curb-inlet diverter 26 shown in FIGS. 1, 3-5, 7 and 9, which has the vertical side of the supports 18 pointing down.)
Of course, catch basins may have designs with such things as their size, shape, and/or orientation, or the location, number, and/or size of their inlet openings or drain openings being different from any of those described or shown herein. It should be understood, however, that the present disclosure contemplates and includes all conventional adjustments in the embodiments described or shown herein (including such adjustments in the size, orientation, proportions, and relative positioning of parts) made to accommodate those differences in catch basin designs. For example, an alternative catch basin design may provide a shelf, ledge, or groove, or combination thereof, built into one or more of its inner walls as a resting place for the supports or even for the filter sheets without supports. An embodiment adapted for installation in such a catch basin design could be made with reduced, or without any, use of other means (such as the support bolt/anchor combinations) for securing the supports and/or filter sheets, without departing from the present disclosure.
While the apparatus and method have been described in terms of what are presently considered to be the most practical and preferred embodiments, it is to be understood that the disclosure need not be limited to the disclosed embodiments. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structures.
