An intelligent integrated remote detection water pressure fire hydrant

Abstract

The invention discloses an intelligent integrated fire hydrant achieving remote water pressure detection. The fire hydrant comprises a solar cell panel, an annular antenna, a fire hydrant dust cap, an M2M module, a power supply, a transversely arranged water valve screw, a sensor cable through tube, a fire hydrant body, a vertically arranged water valve screw, a bearing, a water vale screw fixed base, a water check valve base, a middle section with a pressure sensor and an elbow; the fire hydrant dust cap is connected to the upper portion of the fire hydrant body, the solar cell panel is arranged on the upper portion of the fire hydrant dust cap, the fire hydrant dust cap is internally provided with the M2M module and the annular antenna, and the power supply is arranged on the upper portion of the fire hydrant body. According to the intelligent integrated fire hydrant achieving remote water pressure detection, the water pressure condition can be monitored uninterruptedly in 24 hours by using the M2M module, and data collection is conducted; received data is demodulated and restored to be real water pressure data, and artificial inspection is omitted; by means of the solar cell panel installed on the fire hydrant body and self-contained lithium battery, cycle charging is conducted to ensure electricity needed by the equipment, energy consumption is extremely low, and environmental protection and high efficiency are achieved.

Description

technical field [0001] The invention relates to an intelligent integrated remote detection water pressure fire hydrant. Background technique [0002] As we all know, when fire trucks go to the police, the head truck is basically equipped with some emergency fire water, and the other fire trucks that follow only get water at the fire scene. However, many realistic examples before are when the fire trucks arrive at a certain outdoor When the fire hydrants were opened, many of them were opened because the fire hydrants were in disrepair for a long time, the accessories were missing, and the municipal management department did not repair them in time. They just simply closed the water valve between the urban pipe network and the fire hydrants, so that the outdoor fire hydrants were actually useless. Water, and the water pressure in some fire hydrants is very low, which cannot meet the requirements of fire water at all, so fire trucks will definitely not be able to get water from...

AI Technical Summary

Problems solved by technology

[0004] 1. The valve stems of the old outdoor fire hydrants are all facing upwards, which results in a period of use, usually about one year, due to the entry of rainwater and a lot of dust from the upward opening, which makes the fire The valve stem of the hydrant and the flange plate on the top of the fire hydrant are rusted and gradually corroded and rotted. As long as the current outdoor fire hydrants have been used for more than one year, they have basically begun to rust or even rot, causing many outdoor fire hydrants to In actual use, when the valve stem is opened and then tightened, some of the screws on the flange of the pressure plate are corroded and fall off, and cannot be closed. The flange of the pressure plate must be replaced, which takes time and effort and increases maintenance costs.

[0005] 2. The valve stem of the old outdoor fire hydrant is directly in contact with the flange of the pressure plate, without any buffer or force reduction mechanism in the middle. A fire hydrant will be used in the open air or in the field for more than ten years or even decades. Some outdoor fire hydrants The bolt has not been used for a long time. When it needs to be used, it is found that the valve stem and the flange of the pressure plate have been rusted and it is difficult to rotate or cannot be rotated at all. It is more likely that they have been rusted together, which directly causes the entire fire hydrant to be scrapped.

[0006] 3. The old fire hydrants can only know whether there is water after manually using a wrench to unscrew the valve stem. This is too backward and cannot detect the water pressure in real time.

[0007] 4. Most of the old fire hydrants are made of cast iron. This material is easy to crack due to low temperature and the service life is shortened.

The material of cast iron is very brittle and has no toughness, and it will break when slightly bumped
