[0025] The present invention will be further described in detail below with reference to the embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0026] A pipe well water level monitoring and automatic drainage system includes a water level monitoring module, an electrical signal conversion module, and a water level drainage module. The water level monitoring module is installed in the pipe well to sense the water level. The water level monitoring module is electrically connected to the electrical signal conversion module via a wire. The water level drainage module is used to drain water. The water level drainage module and the electrical signal conversion module are electrically connected via a wire. When the water level monitoring module detects the water level, the electrical signal conversion module, which is electrically connected to the water level monitoring module, is switched on. When the electrical signal conversion module is switched on, the water level drainage module begins drainage.

[0027] like Figure 1 As shown, a specific embodiment is shown. In this embodiment, the water level monitoring module is configured as a water level sensing sensor 1, and the electrical signal conversion module is configured as a liquid level relay 2. When the water level sensing sensor 1 monitors the water level, the liquid level relay 2 is turned on.

[0028] The water level reduction module is configured as a submersible pump 3, an AC power supply 4 and a drain pipe 5. The AC power supply 4 is used to power the submersible pump 3. The drain pipe 5 is connected to the submersible pump 3 for drainage. The liquid level relay 3 is connected to the power supply line between the AC power supply 4 and the submersible pump 3, so that the conduction of the liquid level relay 3 can control whether the submersible pump 3 is connected to the AC power supply 4.

[0029] In addition, a line protection module is provided between the liquid level relay 2 and the power supply line to protect the safe operation of the liquid level relay 2 and prevent damage due to high current. For example, the line protection module is configured as an AC contactor.

[0030] In another embodiment, based on the previous embodiment, the water level monitoring module is configured as two water level sensors 1 arranged along the height of the pipe well, namely water level sensor 1 and water level sensor 2. When the upper water level sensor 1 detects the water level, the external control device controls the operating power of the submersible pump 3 to increase. The reason is that when the lower water level sensor 1 detects the water level, it indicates that drainage is necessary, while when the upper water level sensor 1 detects the water level, it indicates that the drainage efficiency is too low and the water level is continuing to rise. Therefore, it is necessary to control the operating power of the submersible pump 3 to increase to improve drainage capacity.

[0031] In addition, to obtain information about the rate of water level increase between the two water level sensors 1, a timer 6 is added. Timer 6 measures the time interval between the two water level sensors 1 sensing the water level. The shorter the time, the faster the water level rises. A controller 7 is also provided. This controller is connected to the submersible pump 3 and receives timing signals from timer 6. Controller 7 controls the operating power of submersible pump 3 based on these timing signals. For example, when timer 6 reaches 5 minutes, submersible pump 3 is controlled to operate at a 90% duty cycle supply voltage. When timer 6 reaches 15 minutes, submersible pump 3 is controlled to operate at a 70% duty cycle supply voltage. When timer 6 reaches 30 minutes, submersible pump 3 is controlled to operate at a 60% duty cycle supply voltage.

[0032] The above solution is an illustrative example. During actual installation and configuration, relevant parameters were adjusted based on on-site conditions. Timer 6 is configured as a timing component or as a computer program within controller 7. The end of the drain pipe is connected to the intelligent sprinkler system on the construction site's perimeter wall.

[0033] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
