The mounting box 36 is equipped with a main motor 37. One end of the swing arm 1 is installed at the driving end of the main motor 37. When the main motor 37 rotates, it drives the swing arm 1 to swing around the center of the sedimentation tank.

[0041] A first cleaning mechanism 10 and a second cleaning mechanism 4 are arranged along the swing arm 1;

[0042] The first cleaning mechanism 10 includes a first driving member and a brush member 15 rotatably mounted on a driving end of the first driving member, the brush member 15 can contact the lateral wall of the sedimentation tank, the first driving member includes a first cleaning driving seat capable of adjusting the position along the length direction of the swing arm 1, the first cleaning driving seat is equipped with a driving motor, and a cleaning shaft is installed at the driving end of the driving motor.

[0043] The second cleaning mechanism 4 includes a second driving member 40 and a rotating rubber disc 41 rotatably mounted on a driving end of the second driving member 40 . The rotating rubber disc 41 is arranged transversely to contact the transverse wall of the sedimentation tank. A brush block 42 is mounted at the bottom of the rotating rubber disc 41 .

[0044] During cleaning, the main driving member 35 drives the swing arm 1 to swing around the center of the sedimentation tank, so that the first cleaning mechanism 10 and the second cleaning mechanism 4 make circular motions respectively; the brush member 15 of the first cleaning mechanism 10 can contact the lateral wall of the sedimentation tank, and driven by the first driving member, the brush member 15 rotates to scrub the moss and debris on the lateral wall of the sedimentation tank; the rotating rubber disc 41 of the second cleaning mechanism 4 rotates under the drive of the second driving member 40, so that the brush block 42 at the bottom of the rotating rubber disc 41 can contact the lateral wall of the sedimentation tank, and can scrub the moss and debris on the lateral wall of the sedimentation tank; the side walls and bottom walls of the sedimentation tank can be cleaned in multiple directions at the same time, the cleaning coverage rate is high, and the practicality is relatively high.

[0045] In addition, a positioning seat 3 is provided along the swing arm 1, and a support plate 16 for positioning the cleaning shaft 14 is provided below the driving motor 13. A tension spring 33 is arranged obliquely between the support plate 16 and the positioning seat 3 to drive the brush member 15 to fit the side wall of the sedimentation tank. The position of the first cleaning driving seat 11 can also be adjusted to facilitate the brush member 15 to clean at different positions; when the brush member 15 rotates, the tension spring 33 can position it, so that the elastic force can drive the brush member 15 to fit the side wall of the sedimentation tank, thereby improving the cleaning efficiency.

[0046] Specifically, the swing arm 1 is equipped with an adjusting mechanism 2 for adjusting the position of the first cleaning drive seat 11. The adjusting mechanism 2 includes a guide rod 21 arranged along the length direction of the swing arm 1. The first cleaning drive seat 11 is equipped with a guide sliding block 22. The guide sliding block 22 is formed with a guide hole 23 that slidably cooperates with the guide rod 21. When the position of the first cleaning drive seat 11 needs to be adjusted, the guide hole 23 formed in the guide sliding block 22 can be slidably cooperated with the guide rod 21, so that the first cleaning drive seat 11 can be moved along the axial direction of the guide rod 21, thereby adjusting the position of the first cleaning drive seat 11. After the position is adjusted, the position of the brush member 15 installed on the first cleaning drive seat 11 changes accordingly, so that cleaning can be performed at different positions, and the adjustment is more convenient.

[0047] Preferably, there are two guide rods 21, and the swing arm 1 is equipped with a pair of fixed seats 24 arranged at intervals. The guide rod 21 is installed between the two fixed seats 24. By adopting a double guide rod 21 structure, the process and stability of the position adjustment of the first cleaning drive seat 11 are further improved.

[0048] Preferably: the swing arm 1 is provided with a clamp for the first cleaning drive seat 11 after the position is adjusted. After the first cleaning drive seat 11 moves, the clamp can be inserted into the first cleaning drive seat 11 to prevent the first cleaning drive seat 11 from continuing to move, thereby ensuring its position stability.

[0049] A support block 25 is installed on the top of the first cleaning drive seat 11, and a shielding plate 26 is installed on the support block 25. The shielding plate 26 can shield the first cleaning drive seat 11 and the driving motor 13 installed on the first cleaning drive seat 11. The shielding plate 26 can prevent the driving motor 13 from getting wet when it rains, thereby protecting the driving motor 13 and extending its service life.

[0050] Preferably, the drive motor 13 is a brushless motor. The friction of the brushless motor is greatly reduced during operation, the operation is smooth, the noise is much lower, and the maintenance cost is low. When necessary, only some dust removal maintenance is required.

[0051] The first cleaning drive seat 11 is provided with a motor frame 12 for supporting the drive motor 13 , and the side of the motor frame 12 is fixedly connected to the first cleaning drive seat 11 , and the motor frame 12 can be fixedly installed in the first cleaning drive seat 11 by bolts, thereby achieving fixed installation of the drive motor 13 .

[0052] The support plate 16 is formed with a connecting vertical plate 17 which is movably connected to the first cleaning drive seat 11. The connecting vertical plate 17 is arranged vertically to the support plate 16. The connecting vertical plate 17 is formed with a driving hole 18 for the cleaning shaft 14 to pass through. The driving hole 18 is installed with a rolling bearing 19 which is coaxially aligned with the cleaning shaft 14 and for the cleaning shaft 14 to pass through. The cleaning shaft 14 is led out from the driving motor 13, passes through the rolling bearing 19, and is connected to the brush member 15, so that the brush member 15 can rotate. The rolling bearing 19 arranged on the support plate 16 can improve the rotation stability of the cleaning shaft 14.

[0053] Preferably, the connecting vertical plate 17 is movably connected to the first cleaning drive seat 11 through an axial hole, so that the supporting plate 16 can move left and right within a certain range.

[0054] The positioning seat 3 is provided with a connecting screw 31, and the connecting screw 31 is installed with a locking nut 32. One end of the tension spring 33 is nested in the connecting screw 31. The support plate 16 is provided with a tension spring 33 connected to one end. The tension spring 33 can be disassembled through the hook part 34 and replaced with a tension spring 33 with different elastic force. The disassembly is convenient. The elastic force of the tension spring 33 can slightly deflect the supporting vertical plate inward, so that the brush part 15 installed on the cleaning shaft 14 keeps in contact with the side wall of the sedimentation tank, and the cleaning is cleaner.

[0055] The first driving member is arranged on the front side wall of the swing arm 1, and the second driving member 40 is arranged on the rear side wall of the swing arm 1. The transmission structure of the second driving member 40 is the same as the transmission structure of the first driving member; therefore, a second cleaning driving seat 50 is adopted, and the second cleaning driving member is provided with a driving motor. The rotating rubber disc 41 is also driven by the driving motor to rotate the shaft body, so that the rotating rubber disc 41 rotates. The rotating rubber disc 41 is formed by rubber material, and the brush block 42 installed on the rotating rubber disc 41 rotates to contact the lateral wall of the sedimentation tank to achieve the removal of moss.

[0056] Similarly, the swing arm 1 is equipped with an adjusting mechanism for adjusting the position of the second cleaning drive seat 50. The adjusting structure can adjust the position of the second cleaning drive seat 50 to facilitate cleaning at different positions.

[0057] It should be noted that the sedimentation tank has a plurality of annular grooves on its periphery, and a partition wall is provided between two adjacent annular grooves. The bottom surface of the rotating rubber disc 41 can contact the top wall of the partition wall to clean the moss on the top wall of the partition wall.

[0058] A third cleaning mechanism 43 is arranged along the swing arm 1, and the third cleaning mechanism 43 includes a driving arm 51 connected to the swing arm 1 and capable of being swung laterally. A first cleaning rod 44 and a second cleaning rod 45 arranged longitudinally are installed along the driving arm 51, and a moss scraper 46 in contact with the lateral wall of the sedimentation tank is installed at the bottom of the first cleaning rod 44 and the second cleaning rod 45; when the swing arm 1 makes a swinging motion, the first cleaning rod 44 and the second cleaning rod 45 make a circular motion, and the moss scraper 46 can scrape the moss on the bottom wall of the sedimentation tank to ensure the cleanliness of the annular groove.

[0059] Preferably, the first cleaning rod 44 is close to the corners of the sedimentation tank, and a connecting rod 47 and a connecting spring 48 are provided between the driving arm 51 and the swing arm 1. The elastic force of the connecting spring 48 can drive the moss scraper 46 at the outer end to the corners of the sedimentation tank, and the driving arm 51 will move slightly outward so that the moss scraper 46 of the first cleaning rod 44 contacts the corners of the bottom wall of the sedimentation tank. When the first cleaning rod 44 makes a circular motion, the moss scraper 46 can clean the moss in the dead corners of the bottom wall of the sedimentation tank.

[0060] Preferably, the second cleaning rod 45 is installed with a compression spring 49 that drives the moss scraper plate 46 to elastically contact the lateral wall of the sedimentation tank. Under the elastic drive of the compression spring 49, the moss scraper plate 46 will buffer downward and elastically contact the bottom wall of the sedimentation tank. When the second cleaning rod 45 makes a circular motion, the moss scraper plate 46 maintains frictional contact with the bottom wall of the sedimentation tank, and the performance of removing moss is relatively stable.

[0061] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
