For example, when the diameter of the water intake main pipe 100 is large, three or more support units 310 can be set in each support assembly 300 to support and fix the water intake main pipe 100, so as to achieve a better supporting and fixing effect. When the length of the water intake main pipe 100 is long, multiple water intake assemblies 800 can be arranged at intervals along the length direction of the water intake main pipe 100, so as to support and fix different positions of the water intake main pipe 100 when taking water.

By arranging the liquid level sensor 850 and the distance sensor 860 on the water intake cover 810, the water level inside the drilling body 400 can be monitored. At the same time, in the process of placing the water intake main pipe 100 into the drilling body 400, the distance between the water intake cover 810 and the bottom of the drilling body 400 can be monitored in real time to prevent the water intake cover 810 from colliding with the bottom of the drilling body 400.

[0064] During specific implementation, only one of the liquid level sensor 850 and the distance sensor 860 may be provided on the water intake cover 810 according to actual needs.

[0067] After the water treatment box 200 is installed, the water intake pipe 100 needs to be placed in the drilling body 400 for water intake operation. Before placement, the slide plate 317 is manually moved upward under the action of the slider 316 and the slide rail 315 to open the mounting frame 313. After the water intake position is determined, a control command is issued to the electric telescopic rod through the control panel 210 located on the water treatment box 200 to extend its output end, drive the support part 312 to slide to one side, and make the multiple support blocks 3122 arranged at intervals on the support plate 3121 abut against the well wall of the drilling body 400 to fix the water intake pipe 100 to prevent it from shaking when taking water. In this process, the distance sensor 860 can be used to monitor the distance between the water intake cover 810 and the bottom of the drilling body 400 in real time to prevent the water intake cover 810 from colliding with the bottom of the drilling body 400.

[0068] When taking water, the control panel 210 is turned on, and the water intake valve and the water intake pump are turned on through the control panel 210. Under the driving action of the water intake pump, the water in the drilling body 400 enters the water intake main pipe 100 through the multiple water intake branches 830, and reaches the water intake tank 220 of the water treatment box 200 along the water intake main pipe 100. After the water level in the water intake tank 220 reaches the set height, the first driving pump 280 drives the buffered water in the water intake tank 220 to enter the filter tank 230 through the first water delivery pipe, and the solid impurities in the water are filtered under the action of the multi-layer filter screen. The filtered water enters the electric treatment tank 240 through the second water delivery pipe under the action of the second driving pump 290 for electrochemical treatment to remove one or more of bacteria, viruses, heavy metals, organic matter, suspended matter and turbid matter in the water. The water after the electrochemical treatment is discharged to the set position through the drain pipe 270.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
