  • Patent number: 11167161
    Abstract: The hydrant monitoring system determines whether water is present in a dry-barrel fire hydrant. The hydrant monitoring system couples to a port of the hydrant using a hydrant port adapter. The hydrant monitoring system supports an operator interface unit mounted within a protective frame next to the hydrant on a fixed arm. A movable arm carries a distance sensor aimed downward that slides into and out of the hydrant on the fixed arm. The hydrant monitoring system is used by making a first distance measurement outside of the hydrant, making a second distance measurement inside of the hydrant, and subtracting the two to determine how far below ground level the bottom of the barrel is. If the bottom is not at a predetermined depth, a request to drain or service the hydrant may be initiated.

  • Patent number: 11054404
    Abstract: A system including an active ventilation device and a system controller. The active ventilation device is installed in an underground vault and generates an exhaust flow from the vault having an exhaust rate. The system controller is configured to determine that a reading received from a selected gas sensor indicates that a manhole event is occurring, and instruct the active ventilation device to change the exhaust rate when the reading indicates that the manhole event is occurring. The system controller is configured to receive at least one sensor reading after the exhaust rate has been changed, determine whether the selected gas sensor is exhibiting drift based at least in part on the sensor reading(s), and perform an action when the system controller determines the selected gas sensor is not exhibiting drift. The action includes notifying a user and/or instructing the active ventilation device to alter the exhaust rate.

  • Publication number: 20090025798
    Abstract: Improvements in present day fire hydrants are presented. The improvement relates to a fire hydrant where the above ground structure is essentially removed and is replaced with an adaptable connection. The connection uses the same mounting hole pattern as used in the above ground hydrant. In operation, the adaptable connection is protected by a hinged cover that is opened to provide access to the adaptable connection. The adaptable connection includes a bayonet type connection where a portable fire hydrant is secured and rotated to start the flow of water.

  • Publication number: 20080245420
    Abstract: A nozzle attachment device for retrofitting fire hydrants with additional structure for reducing the potential that those with ill intent can foul municipal water supplies by introducing toxins or other materials into fire hydrants. Various embodiments include a housing with a channel and connection means for the fire hydrant's nozzle for efficient and cost effective installation, a seat and a valve within the channel which interact to close off portions of the hydrant otherwise available for receipt of toxic or other materials when the fire hydrant nozzle cap is unscrewed and open.

    Abstract: The present invention relates to methods and devices for retrofitting fire hydrants with additional structure for reducing the potential that those with ill intent can foul municipal water supplies by introducing toxins or other materials into fire hydrants. Various embodiments include a replacement hydrant body having an enlarged diameter portion that can be installed to replace an existing hydrant body. The replacement hydrant body can include a secondary valve comprising a seat, biasing structure, and a restriction member to close off portions of the hydrant otherwise available for receipt of toxic or other materials when the fire hydrant nozzle cap is unscrewed and open.

  • Patent number: 7314057
    Abstract: A fluid delivering hydrant providing a valve actuated assembly with enclosing shroud and water resistive doom handle assembly to protect the assembly from exposure to the weather while preventing entry of rainwater into a building structure upon the roof of which the device has been installed. The fluid hydrant also includes structures for preventing water or fluid from remaining in the hydrant after the fluid flow valve is closed. This presents possibly freezing of the fluid and damage to the system.

  • Patent number: 7278442
    Abstract: The vented port-cap includes a check-valve, which admits air into the barrel of the hydrant when the pressure inside is lower than the pressure outside. After an inspection of the hydrant, the hydrant can be left to drain by itself, even though the port-cap has been replaced and tightened.

  • Patent number: 7140212
    Abstract: A locking cover plate can be selectively locked in position on a stortz pipe end fitting or can be unlocked and removed for access to the open pipe end. The cover plate includes a sliding plate that is driven laterally outward into a deployed state by rotating a drive bolt. The drive bolt is coupled to the sliding plate through a torque limiting coupling that transfers the rotation of the drive bolt to translating movement of the latch bar with a cam plate. Movement of the sliding plate is indicated through a front of the cover plate such that the user can identify whether the cover plate is locked on a fitting or simply placed on the fitting without the lock engaged.

  • Patent number: 6948512
    Abstract: A device and method for automatically flushing hydrants. The device is installed externally to an existing hydrant. The device comprises a nipple having an internally threaded collar for attaching the device to a hydrant outlet, a valve, a control for automatically operating the valve, and a lockable box containing at least the valve, the box having an outlet for allowing water from the hydrant to pass from the valve to the exterior of the box. The box functions as an enclosure and may be of any desired configuration.

  • Patent number: 6816072
    Abstract: A detection and signaling apparatus is mountable in a fire hydrant to detect a parameter, such as unauthorized movement of a discharge nozzle cap relative to the fire hydrant. A housing carrying a sensor, such as a motion detector, is mounted inside of the cap. The sensor has an output connected to a transmitter. Movement of the cap relative to the fire hydrant activates the motion detector which generates an output signal causing the transmitter to remotely transmit a tamper detection signal and, also, a fire hydrant location identification code. A pressure sensor can also be coupled to the transmitter to sense water supply main pressure and water flow through the fire hydrant.

  • Patent number: 6802338
    Abstract: A fire hydrant securing arrangement utilizes a magnetic detent to couple an outer body to a center post so that when a wrench with a permanent magnet is mated with the outer body, the magnetic detent connects the outer body to the center post. The center post has an end with a polygonal recess which complements the shape of the hydrant operating nut. The recess is within an insert that has a polygonal periphery engaged by a polygonal inner wall of the center post. The insert is interchangeable with other inserts having recesses of different sizes and configurations so that the securing arrangement is readily acceptable to fire hydrants having different operating nuts of different sizes.
