Fire hydrant water leakage alarm detection device

Abstract

The invention provides a fire hydrant water leakage alarm detection device. A moving plate is mounted in a sleeve in a sliding manner, a compression spring is fixedly connected to the lower surface ofthe moving plate, a magnet is arranged in the moving plate, a corresponding coil is arranged in the sleeve below the magnet, an ejector rod is fixedly installed at the right end of the moving plate,and a graduated scale is installed in the top end of the ejector rod in a sliding mode. A sliding plate at the bottom of a water receiving tank is pressed to move in a fixed seat by utilizing the gravity of leaked water, the positions of a metal sheet and a variable resistor are adjusted by moving the water receiving tank in the fixed seat, it is guaranteed that a magnetic field generated by the coil pushes the magnet, and then the moving plate is pushed to move in the sleeve, the ejector rod is pushed to make contact with a control switch, a warning lamp is turned on, and it is indicated thatthe fire hydrant leaks water; if no water leakage condition occurs, the warning lamp does not respond; and when the water leakage degree is too high, the ejector rod continues to move to drive the graduated scale to move rightwards, and the water leakage degree of the fire hydrant can be known conveniently and visually.

Description

technical field [0001] The invention belongs to the technical field of fire detection, and in particular relates to a water leakage alarm detection device for a fire hydrant. Background technique [0002] A fire hydrant is a fixed fire tool, which is distributed in different locations in the city. It is mainly used to control combustibles, isolate combustion aids, and eliminate ignition sources. Fire hydrants are mainly used for fire trucks to supply water from municipal water supply networks or outdoor firefighting It is one of the important fire-fighting facilities to put out the fire by taking water from the pipe network. Before the fire hydrant is put into use, it is necessary to carry out water leakage detection to judge whether the fire hydrant is qualified. [0003] When inspecting a fire hydrant, it is often filled with water to detect whether it is leaking. Often too many pores will not be detected, and it is impossible to know whether there is a leak at the first t...

Problems solved by technology

[0003] When inspecting a fire hydrant, it is often filled with water to detect whether it is leaking. Often too many pores will not be detected, and it is impossible to know whether there is a leak at the first time. The accuracy of the detection result is not high. In addition, it is impossible to directly The degree of water leakage of the fire hydrant was observed, and the detection efficiency was low. Therefore, in view of this, the existing structure and defects were studied and improved, and a water leakage alarm detection device for fire hydrants was provided in order to achieve more practical value.
