A fire hydrant leakage alarm detection device

Abstract

The invention provides a fire hydrant water leakage alarm detection device. A moving plate is slidably installed inside the sleeve, a compression spring is fixedly connected to the lower surface of the moving plate, and a magnet is arranged inside the moving plate. Corresponding coils are arranged below and inside the sleeve, a push rod is fixedly installed on the right end of the moving plate, and a scale is slidably installed inside the top end of the push rod. Use the gravity of the leak to press the slide plate at the bottom of the water tank to move inside the fixed seat, and adjust the position of the metal sheet and the variable resistor by moving the water tank inside the fixed seat, so as to ensure that the magnetic field generated by the coil pushes the magnet, and then pushes the moving plate in the sleeve. Move the inside of the barrel, push the ejector rod to contact the control switch, the warning light is on, indicating that the fire hydrant is leaking, if there is no water leakage, the warning light has no response, when the degree of water leakage is too high, the ejector rod continues to move and the scale moves to the right, It is convenient and intuitive to understand the degree of fire hydrant leakage.

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.
