[0021] The maximum and minimum water levels are set by the control module. Under normal conditions, the first solenoid valve 51 and the fourth solenoid valve 81 are in a normally open state. Based on normal water demand, the water pump 9 is activated, and the water in the wellbore is delivered to the water-using mechanism via the extraction pipe 3, the first branch pipe 5, and the fourth branch pipe 8. When the liquid level sensor 2 detects that the water level is lower than the minimum water level, the control module controls the first solenoid valve 51 and the fourth solenoid valve 81 to close, the second solenoid valve 61 and the third solenoid valve 71 to open, and the water pump 9 is activated. Water from the injection source enters the wellbore via the third branch pipe 7, the second branch pipe 6, and the extraction pipe 3. When the liquid level sensor 2 detects that the water level is higher than the maximum water level, the control module controls the second solenoid valve 61 and the third solenoid valve 71 to close, and the first solenoid valve 51 and the fourth solenoid valve 81 to reopen.

[0022] In another embodiment, a filter assembly 4 is provided on the pumping and injection pipe 3 , and the filter assembly 4 is used to filter the water during the pumping and injection processes.

[0023] In another embodiment, Figure 2As shown, the filter assembly 4 includes a main body 41, in which a filter chamber 43 is provided. Ports 42 communicating with the filter chamber 43 are symmetrically provided on both sides of the main body 41. A slag removal hole 44 communicating with the filter chamber 43 is provided at the bottom of the main body 41. A collection barrel 46 is provided at the slag removal hole 44. A filter plate 47 is provided at the junction of the port 42 and the filter chamber 43. The bottom of the filter plate 47 is hinged to the main body 41 via a rotating shaft. A torsion spring is provided on the rotating shaft. The filter plate 47 closes the port 42 under the action of the torsion spring. When pumping water, the left filter plate 47 opens under the impact of the water flow, and the impurities intercepted by the right filter plate 47 are filtered and collected by the collection barrel 46. When filling water, the right filter plate 47 opens under the impact of the water flow, and the impurities intercepted by the left filter plate 47 are filtered and collected by the collection barrel 46, thereby achieving two-way filtration.

[0024] In another embodiment, a valve 45 is installed at the slag removal hole 44, and the collecting cylinder 46 is detachably installed on the valve 45. By closing the valve 45, the collecting cylinder 46 can be disassembled and cleaned.

[0027] In another embodiment, a cleaning roller 48 is slidably mounted within the filter chamber 43; the outer diameter of the cleaning roller 48 is the same as the inner diameter of the filter plate 47, facilitating cleaning of the filter plate 47 by the cleaning roller 48. The cleaning roller 48 comprises a support shaft 481, a rotating sleeve 482, and scraping teeth 483. Sliders are fixedly mounted at both ends of the support shaft 481, and a slide rail 49 is provided on the inner wall of the filter chamber 43 to accommodate the slides. The rotating sleeve 482 is rotatably mounted on the support shaft 481. A plurality of scraping teeth 483 are provided, and the plurality of scraping teeth 483 are evenly distributed on the outer circumference of the rotating sleeve 482. When pumping water, the filter plate 47 on the left is opened by the impact of the water flow, and is filtered by the filter plate 47 on the right. The water flow drives the cleaning roller 48 to slide to the right and close to the filter plate 47 on the right. The water flow drives the scraper 483 to rotate, scraping off the impurities remaining on the filter plate 47 on the right, and the impurities are collected by the collecting tube 46; when filling water, the filter plate 47 on the right is opened by the impact of the water flow, and is filtered by the filter plate 47 on the left. The water flow drives the cleaning roller 48 to slide to the left and close to the filter plate 47 on the left. The water flow drives the scraper 483 to rotate, scraping off the impurities remaining on the filter plate 47 on the left, and the impurities are collected by the collecting tube 46; the filter plate 47 is cleaned by the cleaning roller 48 to prevent the filter plate 47 from being blocked.
