All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 6 This invention provides a wastewater treatment tank inner wall cleaning device, including a cleaning main board 1, an auxiliary cleaning plate A 2 installed on one side of the cleaning main board 1, and an auxiliary cleaning plate B 3 installed on the side of the cleaning main board 1 away from the auxiliary cleaning plate A 2. The auxiliary cleaning plates A 2 and B 3 are symmetrically distributed on both sides of the cleaning main board 1. A sliding groove 4 is formed on the outer surface of the cleaning main board 1, and a movable block 5 is movably installed inside the sliding groove 4. A rotating cylinder 6 is movably installed inside the movable block 5, and one end of the rotating cylinder 6 extends to the outside of the movable block 5. A limiting frame 7 is fitted over the movable block 5, and a fixing rod 8 is provided at the end of the limiting frame 7. One end of the fixing rod 8 passes through the movable block 5 and is threaded to the inside of the cleaning main board 1.

[0029] This application uses the main cleaning plate 1 as the main cleaning surface, and with the A auxiliary cleaning plate 2 and B auxiliary cleaning plate 3 symmetrically distributed on both sides, a larger cleaning contact surface can be formed to adapt to the situation where the inner wall of the sewage tank needs to be cleaned over a large area.

[0030] The limiting frame 7 is provided with a sliding groove on the side away from the moving block 5. A connecting rod 71 is slidably installed inside the sliding groove. One end of the connecting rod 71 is located in the sliding groove, and the other end extends to the A auxiliary cleaning plate 2 and is fixed.

[0031] The connecting rod 71 is in contact with the outer surface of the A auxiliary cleaning plate 2, and the end of the connecting rod 71 is provided with a rotating rod 9. The rotating rod 9 fixes the connecting rod 71 to the A auxiliary cleaning plate 2, and one end of the rotating rod 9 extends into the interior of the A auxiliary cleaning plate 2 and is fixed. Through the setting of the connecting rod 71, in conjunction with the limiting frame 7, the stability of the A auxiliary cleaning plate 2 during the unfolding and retraction process can be ensured.

[0032] A connecting frame 10 is fixedly installed at one end of the A auxiliary cleaning plate 2 near the cleaning main plate 1, and the outer surface of the cleaning main plate 1 is in contact with the inner wall of the connecting frame 10. The two are fixed by bolts 11. By setting the bolts 11, the positions of the A auxiliary cleaning plate 2 and the cleaning main plate 1 can be fixed and separated.

[0033] A support rod 12 is fixedly installed at the bottom of the cleaning main board 1. A first extension rod 13 is sleeved on the outer surface of the support rod 12, and the support rod 12 moves back and forth along the first extension rod 13. The height of the cleaning device described in this application can be adjusted by adjusting the relative position of the support rod 12 and the first extension rod 13.

[0034] To improve the ease of height adjustment of the cleaning device described in this application, a pressing block 14 is provided on the support rod 12, and one end of the pressing block 14 extends to the outside of the support rod 12; the other end of the pressing block 14 is fixed to the trapezoidal strip 15, the trapezoidal strip 15 is made of elastic material, and two ends of the trapezoidal strip 15 are fixedly installed with snap-fit ​​blocks 16, and one end of the snap-fit ​​blocks 16 is snapped into the inside of the first extension rod 13; by changing the straight distance between the connection points at both ends of the trapezoidal strip 15 by pressing the block 14, the two snap-fit ​​blocks 16 are driven to separate or move closer.

[0035] It should be noted that a telescopic spring 17 is fixedly installed on the side of the trapezoidal strip 15 away from the pressing block 14, and one end of the telescopic spring 17 is fixedly connected to the inner wall of the support rod 12. Both the telescopic spring 17 and the trapezoidal strip 15 are located inside the support rod 12.

[0036] To accommodate more cleaning pool heights, a second extension rod 18 is installed on the outer edge of the first extension rod 13, and one end of the first extension rod 13 extends to the inner wall of the second extension rod 18 and is slidably connected thereto. The second extension rod 18 is located directly below the support rod 12.

[0037] The working steps of the device in this invention are as follows:

[0038] S1: First, the staff transported the cleaning device described in this application to the designated sewage treatment tank. According to the cleaning requirements of the tank wall, the auxiliary cleaning plate was first unfolded. Using the movable connection between the moving block 5 and the sliding groove 4 of the main cleaning plate 1, the moving block 5 was slid to the front edge of the main cleaning plate 1, so that the A auxiliary cleaning plate 2 was separated from the outer surface of the main cleaning plate 1. Then, in conjunction with the rotating cylinder 6 inside the moving block 5 and the rotating rod 9 on the connecting rod 71, the A auxiliary cleaning plate 2 was unfolded smoothly, so that it was parallel to the main cleaning plate 1. During the unfolding process, the limiting frame 7 and the connecting rod 71 restricted the movement trajectory of the A auxiliary cleaning plate 2 to ensure that the unfolding was smooth and without deviation. After unfolding, the position of the A auxiliary cleaning plate 2 was fixed by the connecting frame 10 and bolt 11 on the outside of the A auxiliary cleaning plate 2. Following the same operation procedure, the B auxiliary cleaning plate 3 was unfolded and fixed, so that the A auxiliary cleaning plate 2, the B auxiliary cleaning plate 3 and the main cleaning plate 1 cooperated to expand the cleaning coverage area.

[0039] S2: Following this, the height adjustment operation is performed. Based on the depth of the sewage treatment tank, the operator presses the pressing block 14 on the outside of the support rod 12, causing the trapezoidal strip 15 at the other end of the pressing block 14 to move inwards towards the support rod 12. This brings the two ends of the trapezoidal strip 15 closer together, thereby causing the locking block 16 at one end of the trapezoidal strip 15 to retract from inside the first extension rod 13 into the support rod 12, releasing the limiting and fixing relationship between the two. At this point, the length of the support rod 12 extending into the first extension rod 13 can be flexibly stretched or contracted. The adjustment method for the second extension rod 18 is similar to that of the first extension rod 13, further adjusting the overall height of the device until the main cleaning plate 1, auxiliary cleaning plate A 2, and auxiliary cleaning plate B 3 precisely fit the corresponding height of the tank wall. After adjustment, the pressing block 14 is released, and the telescopic spring 17 drives the trapezoidal strip 15 and locking block 16 to reset, re-lock and fix, thus locking the device height. This completes the adjustment of the cleaning coverage and height of the sewage cleaning tank inner wall cleaning device described in this application.
