Abstract

The utility model relates to a self-protecting fire hydrant. According to the self-alarm fire hydrant, an electronic flow meter and a protection switch are fixed with the bottom of a fire hydrant body, the electronic flow meter transfers the produced flow to a control unit, the control unit controls to automatically turn off an electric valve when receiving a mass flow, so that the water cannot flow out to avoid waste of water resources, a communication module also receives an electric signal from the control unit when the electric valve is turned off so as to send an alarm to a remote command center, then firefighters can repair the damaged fire hydrant and turns on the electric valve after arriving at the scene of the accident in time, so the electric valve works normally; when the fire hydrant is used for fire rescue, the protection switch is pressed down firstly to turn off the control unit, and a water source is not turned off by the electric valve because of the flow information produced by the electronic flow meter.

Description

A kind of self-shield fire hydrant

Technical field

The utility model relates to fire-fighting equipment field, particularly a kind of self-shield fire hydrant.

Background technology

Outdoor Fire Hydrant plays vital effect in daily fire rescue as fire-fighting emergent equipment, often because some driver's mistakes are driven after causing fire hydrant to be clashed into and are caused damage, the fracture of generation fire hydrant, if do not have on-call maintenance can cause a large amount of water resource waste; In some remote sections or night some without good driver, often select to escape, when around the masses find, pass by the time more of a specified duration, water resource waste is huge.

Summary of the invention

The purpose of this utility model is to provide a kind of self-shield fire hydrant, and this fire hydrant structure is simple, while being caused fire hydrant to damage by vehicle collision, can automatically close in time protection fire hydrant, avoids the waste of water resource.

The utility model solves the technical scheme that its technical problem adopts,

A kind of self-shield fire hydrant; which comprises at least fire hydrant body; it is characterized in that: the inlet channel place of fire hydrant body bottom is fixed with electronic flowmeter and electrically operated valve; on the sidewall of fire hydrant body below, be furnished with protection switch; electronic flowmeter and protection switch are all electrically connected to control module, and control module is also electrically connected with electrically operated valve.

Described control module is also electrically connected with communication module.

Described this external surface of fire hydrant has reflective tape or fluorescent material.

Described protection switch is arranged on the sidewall of fire hydrant body below distance ground 5-10cm.

There is protective cover to be opened/closed in described protection switch outside.

Described control module is arranged in electronic flowmeter sidepiece.

Described electrically operated valve is positioned at inlet channel and below, junction, fire hydrant body bottom.

The beneficial effects of the utility model are that this automatic alarm fire hydrant is owing to having fixed electronic flowmeter and protection switch in fire hydrant body bottom, electronic flowmeter can be passed to control module by the flow value of generation, in flow when counting that control module receives large flow, can be controlled electrically operated valve and automatically close, water cannot be flowed out, avoid the waste of water resource; The simultaneous communications module that electrically operated valve is closed also can receive the signal of telecommunication of control module, thereby reports to the police to remote command center, and fire fighter repairs the fire hydrant damaging and opens electrically operated valve after rushing in time spot, can work; When using fire hydrant to carry out fire rescue, the protection switch that should take the lead in pressing, protection switch can closing control unit, and the flow information that electronic flowmeter is produced can not closed water source by electrically operated valve.

Accompanying drawing explanation

Below in conjunction with embodiment, the utility model is further illustrated.

Fig. 1 is the utility model structural representation;

In figure: 1, fire hydrant body; 2, electronic flowmeter; 3, protection switch; 4, control module; 5, electrically operated valve; 6, protective cover; 7, inlet channel; 8, communication module.

The specific embodiment

As shown in this self-shield fire hydrant structure schematic diagram of Fig. 1, which comprises at least fire hydrant body 1, wherein, inlet channel 7 places of fire hydrant body 1 bottom are fixed with electronic flowmeter 2 and electrically operated valve 5,, the inlet channel place that electronic flowmeter 2 is fixed on fire hydrant body 1 bottom can guarantee when fire hydrant body 1 is subject to clashing still can normally detect flow; On the sidewall of fire hydrant body 1 below, be furnished with protection switch 3; electronic flowmeter 2 and protection switch 3 are all electrically connected to control module 4; control module 4 is also electrically connected with electrically operated valve 5; protection switch 3 is for closing control unit 4; while guaranteeing normal fire fighting, electrically operated valve 5 can not closed, and electronic flowmeter 2, control module 4, electrically operated valve 5 all pass through mains-supplied.

Protection switch 3 is arranged on the sidewall of fire hydrant body 1 distance ground, below 5-10cm, and meanwhile, there is protective cover 6 to be opened/closed in protection switch 3 outsides, and protective cover 6 can play the problem that prevents protection switch 3 maloperations.

Wherein control module 4 is arranged in electronic flowmeter 2 sidepieces, and electrically operated valve 5 is positioned at inlet channel 7 and fire hydrant body 1 below, junction, bottom, and while having guaranteed equally that fire hydrant body 1 is subject to clashing, electrically operated valve 5 still can work, and closes inlet channel 7;

The structure of fire hydrant body 1 is identical with existing fire hydrant structure, at this, does not describe in detail, and control module 4 is single-chip microcomputers, and electronic flowmeter 2 and electrically operated valve 5 are widely used in other field, belong to prior art, and structure does not describe in detail.

During use, electronic flowmeter 2 can be passed to control module 4 by the flow value of generation, can control electrically operated valve 5 and automatically close when control module 4 receives the flow counting of large flow, and water cannot be flowed out, and avoids the waste of water resource; When using fire hydrant to carry out fire rescue, should take the lead in pressing protection switch 3, protection switch 3 can closing control unit 4, and the flow information that electronic flowmeter is produced can not closed water source by electrically operated valve 5.

Embodiment 2

Control module 4 in above-described embodiment is also electrically connected with communication module 8, and communication module 8 is connected to remote command center,

The simultaneous communications module that electrically operated valve 5 is closed also can receive the signal of telecommunication of control module, thereby reports to the police to remote command center, and fire fighter repairs the fire hydrant damaging and opens electrically operated valve after rushing in time spot, can work.

Fire hydrant body 1 outer surface has reflective tape or fluorescent material simultaneously, and reflective tape or fluorescent material can effectively play warning function, the Probability of reduction accident at night.
