Description

Technical Field

[0001] This utility model relates to the field of fire protection facilities technology, and specifically discloses a fire hydrant network pressure detection device. Background Technology

[0002] Fire hydrant networks mainly include outdoor fire hydrant networks and indoor fire hydrant networks. Outdoor fire hydrant networks refer to fire hydrant pipe networks that form a fire hydrant pipe ring network on the ground of the community, with an outdoor fire hydrant water supply system installed at certain intervals on the ring network. Its main function is to provide convenience for fire trucks to draw water, and it can also be directly connected to water hoses and water guns to extinguish fires.

[0003] Currently, when testing the water pressure of fire hydrants, the pressure testing nozzle is usually directly installed on the hydrant interface. The high-pressure water flow directly washes over the testing nozzle, causing it to be subjected to instantaneous high pressure, resulting in wear or even breakage. This requires frequent replacement and maintenance. Furthermore, the water in the fire hydrant contains impurities such as rust and silt, which easily adhere to the surface of the testing nozzle, affecting its accuracy. To address these issues, we propose a fire hydrant network pressure testing device. Utility Model Content

[0004] This utility model proposes a fire hydrant network pressure detection device. Through the combined design of elastic element and water-draining plate, the high pressure kinetic energy can be buffered by the elastic displacement of the water-draining plate when water flows, which solves the problem that the sensor is easily subjected to instantaneous high pressure. The filter screen filters the rising water flow, which solves the problem that impurities such as rust and mud adhere to the probe surface of the water pressure sensor and easily affect the probe accuracy.

[0005] This utility model is implemented as follows: a fire hydrant network pressure detection device includes a housing, an inlet pipe fixedly connected to the inner wall of the housing, a drain plate slidably connected to the inner wall of the inlet pipe, a slide cylinder fixedly connected to the inner wall of the housing, a slide rod slidably connected to the inner wall of the slide cylinder, the outer surface of the slide rod being connected to the outer surface of the drain plate, an elastic element fixedly connected to the outer surface of the drain plate, the outer surface of the elastic element being connected to the inner wall of the housing, multiple water inlets opened on the outer surface of the drain plate, a filter screen fixedly connected to the inner wall of the housing, a water pressure sensor fixedly connected to the inner wall of the housing, and a pressure gauge fixedly connected to the outer surface of the housing.

[0006] As a preferred embodiment of the fire hydrant network pressure detection device of this utility model, a sealing ring is fixedly connected to the outer surface of the drainage plate, and a drain valve is fixedly connected to the bottom surface of the outer shell.

[0007] As a preferred embodiment of the fire hydrant network pressure detection device of this utility model, a fire water pipe is fixedly connected to the outer surface of the housing, and a fire connector is fixedly connected to the outer surface of the fire water pipe.

[0008] As a preferred embodiment of the fire hydrant network pressure detection device of this utility model, a support frame is fixedly connected to the inner side wall of the outer shell, and tempered glass is fixedly connected to the outer surface of the outer shell.

[0011] The beneficial effects of this utility model are:

[0012] This fire hydrant network pressure detection device uses a drainage plate that moves within the inlet pipe. Combined with an elastic element, a sliding cylinder, and a sliding rod, the device buffers high-pressure kinetic energy through the elastic displacement of the drainage plate when water flows, preventing the sensor from directly bearing instantaneous high pressure and thus improving the device's durability. The filter screen filters the rising water flow, preventing impurities such as rust and silt from adhering to the probe surface of the water pressure sensor, reducing the impact of impurities on the water pressure sensor probe.
