Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-4 As shown, the utility model provides a technical solution: a pool wall descaling device for an acidic wastewater treatment neutralization pool, comprising a driving mechanism 2 installed on the top of a pool body 1 and a descaling mechanism 3 used in conjunction with the driving mechanism 2;

[0028] The driving mechanism 2 includes an outer frame 21 and an inner frame 22 fixed to each other. The outer frame 21 is fixed to the top of the opening of the pool body 1. The outer frame 21 completes the fixed installation of the entire driving mechanism 2 and the top opening of the pool body 1.

[0029] The inner frame 22 is fixed to the inner side of the outer frame 21. In order to facilitate the normal use of the scale cleaning mechanism 3, the inner frame 22 is suspended in the area above the opening of the pool body 1, thereby facilitating the contact between the scale cleaning mechanism 3 and the inner wall of the pool body 1 and facilitating the completion of the scale cleaning operation of the pool wall.

[0030] A belt ring 23 is movably connected to the outer frame 21, and teeth 24 are provided on the outer side of the belt ring 23. A driving gear 25 is also rotatably connected to the outer frame 21, and the driving gear 25 is meshed with the teeth 24. A gear motor 26 for driving the driving gear 25 to rotate is also installed on the outer frame 21. The rotation of the gear motor 26 can drive the rotation of the driving gear 25, and the driving gear 25 and the teeth 24 can drive the belt ring 23 to rotate in the outer frame 21, thereby driving the connecting block 27 in the belt ring 23 to move in the inner area of the outer frame 21.

[0031] The cross section of the inner frame 22 is a convex structure, and the corners of the outer frame 21 and the inner frame 22 are rounded, so that the connecting block 27 can move smoothly and avoid the phenomenon that the connecting block 27 jams the belt ring 23.

[0032] In order to improve the stability of the belt loop 23 during its movement, the belt loop 23 is a closed rubber belt loop, and a plurality of anti-slip blocks are fixed at equal intervals at the top and bottom ends of the belt loop 23 , and the anti-slip blocks are slidably connected to the slide grooves at the top and bottom ends of the outer frame 21 .

[0033] A connecting block 27 is fixed in the belt ring 23, and the connecting block 27 is also slidably connected in the outer frame 21, so as to avoid the gravity of the connecting plate 28 and the cleaning motor 29 from tilting in the outer frame 21, thereby avoiding the belt ring 23 from tilting during use, thereby improving the stability of the belt ring 23 during use.

[0034] A connecting plate 28 is fixed to the other side of the connecting block 27, and the other end of the connecting plate 28 is slidably connected to the inner frame 22. A cleaning motor 29 is installed on the connecting plate 28, and the output shaft of the cleaning motor 29 extends to the bottom side of the connecting plate 28. A cleaning mechanism 3 is connected to the bottom end of the output shaft of the cleaning motor 29 through a universal joint, so that the rotation of the cleaning motor 29 can drive the rotation of the cleaning mechanism 3, and the rotation of the cleaning mechanism 3 can complete the cleaning operation of the pool wall of the pool body 1.

[0035] The scale cleaning mechanism 3 is composed of a plurality of scale cleaning units that are connected to each other by snapping. The scale cleaning unit is composed of an intermediate rod 31 and a scale cleaning bristle 32.

The arc-shaped connecting head 41 is rotatably connected to the middle and lower sections of the cleaning unit. Specifically, the arc-shaped connecting head 41 is rotatably connected to the connection between the two middle rods 31 in the middle and lower sections.

[0037] In summary, when in use, the driving mechanism 2 is installed at the top opening of the pool body 1. When the inner wall of the pool body 1 needs to be cleaned, the length of the cleaning unit is completed according to the depth of the pool body 1, and then the cleaning motor 29 is started, so that the cleaning motor 29 drives the cleaning unit of the cleaning mechanism 3 to rotate, and then the pressure between the cleaning unit and the pool wall is adjusted by adjusting the length of the micro hydraulic cylinder 4, so that the descaling operation of the inner wall can be completed during cleaning, and then the gear motor 26 is started, so that the gear motor 26 drives the belt ring 23 to rotate. During the rotation of the belt ring 23, it can drive the connecting plate 28 to move at the opening above the pool body 1. During the movement, the cleaning unit moves along the pool wall until the dirt cleaning operation of the entire pool wall is completed. It is efficient and practical, and easy to promote and use.
