[0040] In a specific embodiment, the drainage module 5 includes: a driving device 51, a plurality of driving switches 52 and water pumps 53 having the same number as the driving switches 52;

[0041] The driving device 51 is connected to the main control module 1 , the driving device 51 is connected to a plurality of driving switches 52 , and the driving switches 52 are connected to the water pump 53 .

[0042] In a specific embodiment, a valve 54 is provided at the water outlet of the water pump 53 , and the valve 54 is connected to the driving device 51 . The speed of drainage can be adjusted by adjusting the opening of the valve 54 .

[0043] In a specific embodiment, it further includes: a display module 11 , which is connected to the main control module 1 .

[0044] The specific working process of this utility model is as follows:

[0045] The main control module 1 is used to realize the overall control function of the drainage device and can be implemented using a Siemens S7-1200 series PLC. The main control module 1 pre-stores low water level threshold, high water level threshold, pressure threshold, vacuum threshold and pre-set electricity price peak and valley period information; the water level detection module 2 includes a low water level detection unit 21 and a high water level detection unit 22, which respectively detect the low liquid level data and high liquid level data of the water tank used to collect water stored in the mine, and at the same time determine the first collection time and the second collection time corresponding to the low water level detection unit 21 and the high water level detection unit 22 respectively through the clock unit 1 41 and the clock unit 2 42;

[0046] When the main control module 1 determines that the low water level data is less than or equal to the low water level threshold, it indicates that the water volume is low. At this time, the main control module 1 outputs a control instruction to the drive device 51. The drive device 51 only controls one drive switch 52 to close and then drives a water pump 53 to continue draining water. At the same time, when the main control module 1 determines that the first collection time is during the peak electricity price period, it can wait until the valley electricity price period. When the first collection time is during the valley electricity price period, it can operate normally.

[0047] When the main control module 1 determines that the low water level data is greater than the low water level threshold but has not reached the high water level threshold, it indicates that the water tank has stored a certain amount of water. At the same time, when the main control module 1 determines that the first acquisition time is in the electricity price valley period, the main control module 1 outputs a control instruction to the drive device 51. The drive device 51 can control multiple drive switches 52 to close (such as 2) and then drive a water pump 53 (the number of water pumps 53 is 2) and adjust the opening of the valve 54 to continue draining water to maintain a stable water level. At the same time, the main control module 1 determines the time between the first acquisition time and the electricity price peak period through the existing control program. If the time distance is close (such as 10 minutes), the main control module 1 controls the drive device 51 to drive all the drive switches 52 to close, and then the drive switches 52 drive all the water pumps 53 to work, so as to discharge more water in the electricity price valley period. When the electricity price peak period is reached, only one set of drive switches 52 and water pumps 53 are kept working. If the time distance is far, no adjustment is required.

[0048] When the main control module 1 determines that the first collection time is in the peak period of electricity price, the main control module 1 determines the time between the first collection time and the valley period of electricity price through the existing program. If the time distance is close (such as 10 minutes), the main control module 1 adjusts the opening of the valve 54 to continue draining water while maintaining the operation of the existing water pump 53 until the valley period of electricity price. If the time distance is far, the main control module 1 outputs a control instruction to the drive device 51. The drive device 51 can control multiple drive switches 52 to close (such as 2) and then drive a water pump 53 (the number of water pumps 53 is 2) and adjust the opening of the valve 54 to continue draining water to maintain a stable water level.

[0049] When the main control module 1 receives the high water level data collected by the high water level detection unit 22, when the high water level data is less than or equal to the high water level threshold, it means that the water volume is large, and another water pump is turned on for drainage on the basis of the original number of working water pumps; when the high water level data is greater than the high water level threshold, it means that the water volume is large, and all the remaining water pumps are turned on for drainage on the basis of the original number of working water pumps, while adjusting the opening of the valve 54 to the maximum, and an alarm is issued at the same time.

[0050] When the main control module 1 works for a period of time, the water in the water tank may accumulate silt due to long-term use, affecting the subsequent water storage in the water tank. The main control module 1 drives the switching switch to turn on the image acquisition module 3 to collect images, and the main control module 1 uses a preset image processor to process the area and thickness of the silt. If the area and thickness reach the preset threshold, an alarm will be issued. Pressure data and vacuum data can also be collected and compared with the corresponding pressure threshold and vacuum threshold. If they do not meet the requirements, an alarm will be issued. The above-mentioned collected data and processing process can be sent to the ground host computer through the wireless communication module.

Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.
