Description

Technical Field

[0001] The present invention relates to the technical field of fire hydrants, and in particular to an intelligent cover for fire hydrants. Background Art

[0002] Common outdoor fire hydrants will only have water gushing out from the bottom after the upper water intake switch is turned on. When the water intake switch is turned off, the remaining water in the hydrant will slowly flow out through the automatic drain valve. Under normal circumstances, no water will remain in the hydrant (to prevent freezing and cracking), so it is necessary to monitor the internal status of the fire hydrant. When taking water normally, you need to open the water outlet caps of different specifications first. For details, please refer to Figure 1 , is a schematic diagram of the structure of different blind covers of fire hydrant water outlets, including φ65mm blind cover 1 and φ100mm blind cover 2. In the process of rotating different blind covers of water outlets, the corresponding actions will be monitored and recorded, and the state inside the fire hydrant will change (for example, when φ65mm blind cover 1 is needed to take water, water will flow through φ100mm blind cover 2). It can be seen that the blind cover of the water outlet of the fire hydrant plays an important role in the working process.

[0003] Today's fire hydrant outlet covers have many functional units (for example, the fire hydrant covers in the prior art all include a pressure monitoring unit, which requires an additional connection unit to be added to the pressure taking point of the water pipe node), which results in the entire product having a very complex structure, high production costs, and a very cumbersome operation process, which is not conducive to the management and monitoring of the overall working status of the fire hydrant; and most fire hydrants use GPRS communication or short-distance communication such as 433MHz, which cannot meet today's high-speed, high-coverage, and low-cost and low-power communication requirements, and is not conducive to market promotion. Summary of the invention

[0004] In view of the above problems, the object of the present invention is to provide a fire hydrant intelligent cover with a simple structure and a flexible communication method.

[0006] The water immersion detection unit includes a non-contact capacitor button for monitoring the water flow state in the fire hydrant, so that when water flows through the waterproof plate, the non-contact capacitor button is controlled to operate and communicate with the main control board;

[0007] The wireless communication unit includes a communication module for communicating and interacting with a remote terminal system, and the communication module is specifically used to match at least one of the following communication standards: NB-IOT, LoRa, 4G and 5G;

[0008] The tilt detection unit is used to monitor the posture change of the cover body, and the posture change includes at least one of the following changes: rotation or tilt.

[0009] As an improvement of the above solution, a gasket is provided on the peripheral side of the waterproof plate for sealing connection with the water outlet of the fire hydrant.
