Description

Energy-concerving and environment-protective hidden regulation and control fire hydrant

Technical Field

The invention relates to the technical field of energy conservation and environmental protection, in particular to an energy-saving and environment-friendly hidden type regulation fire hydrant.

Background

The outdoor fire hydrant is a water supply facility arranged on a fire-fighting water supply pipe network outside a building, is mainly used for a fire truck to take water from a municipal water supply pipe network or an outdoor fire-fighting water supply pipe network to put out a fire, and can also be directly connected with a water hose and a water gun to discharge water to put out a fire.

Traditional outdoor fire hydrant sets up at the road border generally, and in pedestrian's vehicle driving process, scrape the fire hydrant easily, especially under the not good condition of night light lighting condition, cause the damage of personnel, vehicle and fire hydrant very easily.

In addition when meetting the conflagration, the fire fighter need unscrew the valve, huge water pressure not only can lead to the time that the valve was opened longer, serious influence the progress and the ageing of putting out a fire, and also can cause the loss of a large amount of running water of in-process of putting out a fire, after the work of putting out a fire is accomplished, on the one hand near the fire hydrant ponding too much influence pedestrian normally passes, on the other hand still can make this internal running water that can store up of fire hydrant, the freezing pipe phenomenon appears freezing easily in winter, even freeze the fire hydrant body and cause the waste of material loss and water resource, therefore energy-concerving and environment-protective hidden regulation and control fire hydrant should be.

Disclosure of Invention

In order to realize the purposes that the hidden fire hydrant can be returned to suck water while ensuring the water supply pressure, the invention provides the following technical scheme: the utility model provides a hidden regulation and control fire hydrant of energy-concerving and environment-protective, includes the hiding case, the fixed surface of hiding case is connected with the inlet tube, the inside fixedly connected with aqua storage tank of hiding case, and the inside swing joint of aqua storage tank has the forcing pipe, and reset spring has cup jointed on the surface of forcing pipe, and reset spring keeps away from the one end swing joint of forcing pipe and has the piston, reset spring's one end fixedly connected with piston rod is kept away from to the piston, and the surperficial sliding connection of piston rod has the fender to hold the piece, and the drain pipe has been seted up to the inside of piston.

The invention has the beneficial effects that:

1. when fire is needed to extinguish, the gate is manually unscrewed to release water, the water flows into the water storage tank through the water inlet pipe, the piston is extruded to move upwards under the clamping of the return spring along with the increase of water flow in the water storage tank, the piston pushes the sealing plate to be opened upwards, and the piston is positioned in the connecting port, when the piston moves upwards, the retaining block on the surface of the piston rod also moves upwards along with the piston, when the retaining block is contacted with the push plate, the retaining block can be pushed to slide upwards on the surface of the slide rail, so that the connecting port gradually extends out of the ground surface, when the retaining block is contacted with the push plate, the piston does not move any more, the water pressure in the water storage tank is increased, and then the water flows into a drain pipe in the piston from the pressurizing pipe, at the moment, the connection port is lifted, so that the effect of reducing the valve opening pressure and ensuring the forced water supply pressure is achieved.

2. Through water pipe and connector connection, carry out water spray and put out a fire, after the work of putting out a fire is accomplished, close the valve, make rivers no longer gush into the aqua storage tank, the piston loses holding power under the effect of reset spring shrink power, the lapse, and it is slow to the underground movement to drive the connector, in piston downstream, because the forcing pipe is inside reset spring, can extrude the forcing pipe in the time of reset spring shrink, the forcing pipe is extruded and is produced suction force, water in the inside water of hiding the case and the water pipe is sucked back, thereby the water economy resource has been reached, prevent the effect of the inside ponding of hiding the case.

Preferably, the surface of the push plate is hinged with a closing plate, and the closing plate plays a role in enabling the connecting port to form a closed space, so that water supply and pressurization are facilitated.

Preferably, the surface of the closing plate is movably connected with a compression spring.

Preferably, a connector is fixedly connected to one side of the push plate, which is far away from the water storage tank.

Preferably, two side walls inside the hidden box are fixedly connected with sliding rails.

Preferably, the piston rod is internally provided with a flow pipe.

Preferably, the retaining block is triangular, so that the retaining block is more stable.

Preferably, the connector is a bi-pass design, and can be connected with two water pipes to accelerate the fire extinguishing speed.
