[0027] The sludge scraping mechanism 2 includes a support seat 203, the support seat 203 is rotatably connected to the inner bottom of the pool body 1, a rectangular plate 202 is fixedly connected to the top of the support seat 203, a stirring shaft 24 is inserted on the surface of the rectangular plate 202, a vertical plate 28 is fixedly connected to the surface of the stirring shaft 24, a second sludge scraping plate 29 is fixedly connected to the bottom of the vertical plate 28, the second sludge scraping plate 29 is arranged at the inner bottom of the pool body 1, a fixing part 201 is fixedly connected to the top of the vertical plate 28, and first sludge scraping plates 22 are fixedly connected to the surfaces of the fixing parts 201.

[0028] Furthermore, the number of the first scraping plates 22 and the second scraping plates 29 is several. The several first scraping plates 22 are arranged at equal intervals in a ring on the surface of the fixing member 201. The first scraping plates 22 and the second scraping plates 29 can effectively scrape the stubborn sludge inside and on the inner wall of the pool body 1 at the same time, improving the effect of sludge scraping.

[0029] Furthermore, a motor 23 is fixedly connected to the top of the stirring shaft 24. A positioning plate 25 is fixedly connected to the surface of the motor 23. The positioning plate 25 is arranged on the top of the pool body 1. First fixing plates 26 are fixedly connected to both sides of the positioning plate 25. By providing the positioning plate 25, the motor 23 can be supported and fixed.

[0030] Furthermore, second fixing plates 27 are fixedly connected to both sides of the first fixing plate 26. A first limiting groove is formed on the side of the second fixing plate 27 away from the first fixing plate 26. A first limiting rod 21 is inserted into the first limiting groove. The first limiting rod 21 is fixedly connected to the top of the pool body 1. By providing the first limiting rod 21, the stirring shaft 24 can be preliminarily limited.

[0031] Embodiment 2:

[0032] Refer to Figure 4 , and on the basis of Embodiment 1, a loading mechanism is further obtained, which includes a limiting plate 33. The limiting plate 33 is fixedly connected to the top of the first fixing plate 26. Connecting plates 35 are arranged on both sides of the limiting plate 33. The connecting plates 35 are fixedly connected to the top of the pool body 1. By providing the connecting plates 35, the position of the limiting plate 33 itself can be restricted.

[0033] Furthermore, a third limiting groove is formed on the surface of the connecting plate 35. A third limiting rod 34 is inserted into the third limiting groove.

When the second limiting rod 32 is inserted into the first limiting groove opened inside the fixing frame 31, then thread the locking nut onto the surface of the second limiting rod 32 to position the sludge scraping device, thereby realizing the installation of the sludge scraping device. According to the above principle, by repeating the opposite steps, the sludge scraping device can be disassembled. After the sludge scraping device has completed its work, it can be directly disassembled, avoiding affecting the normal use of the tank body 1. At the same time, it can scrape the sludge of different types but the same specification and size of the tank body 1, expanding the scope of use of this sludge scraping device;

[0036] When it is necessary to scrape the stubborn sludge at the bottom and inside of the tank body 1, the motor 23 can be started. The motor 23 drives the stirring shaft 24 to rotate and drives the first sludge scraping plate 22 and the second sludge scraping plate 29 to rotate synchronously. At this time, the first sludge scraping plate 22 and the second sludge scraping plate 29 can effectively scrape the stubborn sludge inside and on the inner wall of the tank body 1 at the same time, improving the effect of sludge scraping. After the sludge is scraped, the scraped sludge can be pumped out by using a sludge suction pump to achieve the effect of cleaning the tank body 1.
