[0022] Embodiment two:

[0023] As Figures 1-5As shown, the utility model discloses a casing 1 fixed cover has cover 2. The motor 3 for providing power source is fixedly installed on the outside of casing 1. Casing 1 swing installation has output shaft 4, and output shaft 4 is connected with motor 3 through speed change gear set 5. Speed change gear set 5 is formed by multiple gears of different sizes, is used to adjust the rotational speed and torque of output shaft 4. Threaded section 6 is equipped on output shaft 4, and threaded section 6 is fixedly installed with rotator 8 through nut 7. Rotator 8 is coaxially arranged with the disc-shaped structure of output shaft 4. The side brush assembly 9 is fixedly connected on rotator 8.

At the same time, the structure is simple, easy to install and maintain, and is suitable for various water surface cleaning scenes.

[0024] Example three:

[0025] As Figures 1-5As shown, the edge brush assembly 9 includes a sleeve piece 10 and cleaning pieces 11. The sleeve piece 10 is a circular ring structure with an inner diameter matching the outer diameter of the rotating body 8, which can be sleeved on the rotating body 8. The outer side of the sleeve piece 10 is fixedly connected with multiple cleaning pieces 11. The cleaning pieces 11 are distributed in a fan shape and uniformly arranged in the circumferential direction of the sleeve piece 10. The sleeve piece 10 and the cleaning pieces 11 are made by integral molding process, with soft rubber material, having good flexibility and wear resistance. In the use process, the sleeve piece 10 is fixed by sleeving with the rotating body 8. When the rotating body 8 rotates, it drives the sleeve piece 10 and the cleaning pieces 11 to rotate together. The multiple cleaning pieces 11 are distributed in a ring shape, forming a circular cleaning area, which can clean the water surface more comprehensively. The sleeve piece 10 is made of elastic material, which can closely fit the rotating body 8 during sleeving, ensuring the stability of the connection. The length, width and thickness of the cleaning pieces 11 are adjusted according to the actual application scene to adapt to different water surface environments. The integrated design of the edge brush assembly 9 simplifies the assembly process, reduces the number of parts and improves the production efficiency. The selection of soft rubber material makes the cleaning pieces 11 have certain deformation ability during work, which can adapt to different shapes of water surface edges and improve the cleaning effect. The edge brush assembly 9 of the embodiment has reasonable structure design, good cleaning effect and long service life. By adjusting the shape and arrangement mode of the cleaning pieces 11, different types of floating objects can be optimized to improve the cleaning efficiency. The overall structure is simple, convenient to replace and maintain, and the use cost is reduced.

[0026] Example four:

[0027] As Figures 1-5As shown, the rotating body 8 is provided with a protruding rib 12 on the outer side, and the sleeve connector 10 is correspondingly provided with a groove 13. The protruding rib 12 and the groove 13 are mutually clamped to form a stable connection. The protruding rib 12 on the rotating body 8 is annularly distributed and uniformly arranged in the circumferential direction. The number of protruding ribs 12 is 3-6. The cross section of each protruding rib 12 is trapezoidal, and the width gradually decreases from the root outward, facilitating engagement with the groove 13. The height of the protruding rib 12 is slightly smaller than the depth of the groove 13, ensuring that the sleeve connector 10 can be completely sleeved into the rotating body 8. The groove 13 on the sleeve connector 10 corresponds to the protruding rib 12 one by one, and the shape and size are matched with the protruding rib 12. The inner wall of the groove 13 is slightly inclined and matched with the side surface of the protruding rib 12, increasing the contact area and improving the connection strength. The bottom of the groove 13 is provided with a certain fillet to avoid stress concentration and prolong the service life. During installation, the sleeve connector 10 is aligned with the protruding rib 12 on the rotating body 8, and is gently pushed so that the protruding rib 12 is embedded in the groove 13. Since the sleeve connector 10 has a certain elasticity, it can be slightly deformed during installation, facilitating the assembly process. After installation is completed, the protruding rib 12 is tightly matched with the groove 13 to form reliable fixation. This clamping type connection has many advantages. First, it enhances the connection stability between the side brush assembly 9 and the rotating body 8, preventing disconnection during high-speed rotation. Second, the clamping structure makes the installation and disassembly of the side brush assembly 9 simple and fast, which can be completed without tools, facilitating daily maintenance and replacement. Third, the design of the protruding rib 12 and the groove 13 increases the contact area and improves the torque transmission efficiency, so that the side brush assembly 9 can better follow the movement of the rotating body 8.

[0028] Example five:

[0029] As Figures 1-5The output shaft 4 is a cylindrical metal shaft, one end of which is connected with the variable speed gear set 5, and the other end of which extends out of the shell 1 for mounting the rotating body 8. The shell 1 movably mounts the output shaft 4 through the first bearing 14, and the cover 2 fixedly mounts the second bearing 15, which is movably connected with the output shaft 4. The inner ring of the first bearing 14 is in interference fit with the output shaft 4, and the outer ring is in interference fit with the inner wall of the shell 1. The first bearing 14 is used to support the radial force and part of the axial force of the output shaft 4. The inner ring of the second bearing 15 is also in interference fit with the output shaft 4, and the outer ring is in interference fit with the bearing seat on the cover 2. The second bearing 15 supports the output shaft 4 together with the first bearing 14. The use of the two bearings forms a double-bearing support structure. When the output shaft 4 rotates at high speed, the first bearing 14 mainly bears the radial load and part of the axial load, and the second bearing 15 mainly bears the remaining axial load and part of the radial load. This double-bearing structure can effectively disperse various forces acting on the output shaft 4, reduce the eccentricity and vibration of the shaft, and ensure that the output shaft 4 remains stable in the high-speed rotating state. In actual work, the motor 3 drives the output shaft 4 to rotate through the variable speed gear set 5. The output shaft 4 is supported by the first bearing 14 and the second bearing 15 and remains stable in the high-speed rotating state. The rotating output shaft 4 drives the rotating body 8 and the edge brush assembly 9 mounted thereon to rotate together, realizing the cleaning of the floating garbage on the edge of the swimming pool. The application of the double-bearing structure enables the output shaft 4 to maintain good coaxiality and running stability in the long-time high-speed rotating working state, effectively prolongs the service life of the edge brush structure, and improves the cleaning efficiency.

[0030] Example six:

[0031] As Figures 1-5As shown, the output shaft 4 of this invention is a cylindrical shaft made of metal, with a flat shaft section 17 at its upper end. The cross-section of the flat shaft section 17 is non-circular. The length of the flat shaft section 17 is approximately equal to the thickness of the rotating body 8 to ensure a good fit. The rotating body 8 has a disc-shaped structure with a flat hole 16 at its center that matches the flat shaft section 17 of the output shaft 4. The hole 16 has a slight clearance fit with the flat shaft section 17 to facilitate installation and disassembly. During installation, the flat shaft section 17 of the output shaft 4 is inserted into the flat hole 16 of the rotating body 8. Since both the flat shaft section 17 and the flat hole 16 have non-circular cross-sections, a key connection is formed between them. This connection method can effectively transmit torque and prevent relative rotation or slippage between the output shaft 4 and the rotating body 8. During high-speed rotating cleaning operations of the side brush, even if significant resistance is encountered, the fit between the flat shaft and the flat hole 16 ensures reliable power transmission and avoids a decrease in cleaning effect due to slippage. To further enhance the reliability of the connection, an external thread is provided at the end of the flat shaft section 17, which is matched with a locking nut 7 with an internal thread. During installation, the locking nut 7 is tightened so that the rotating body 8 is tightly pressed against the shoulder of the output shaft 4, thereby fixing the position of the rotating body 8 axially. This combination of axial locking and radial key connection forms a robust three-dimensional constraint, ensuring that the rotating body 8 will not loosen or fall off under high-speed rotation and frequent start-stop operating conditions.

[0032] Example 7:

[0033] like Figures 1-5 As shown, the rotating body 8 of this utility model is fixedly snapped with a decorative cover 18. The rotating body 8 has a disc-shaped structure and is used to install the side brush assembly 9. A circular groove 13 is provided at the center of the upper surface of the rotating body 8 to accommodate the locking nut 7. Around the circular groove 13, several snap-fit ​​protrusions are evenly distributed on the rotating body 8. These snap-fit ​​protrusions are semi-cylindrical and arranged radially along the rotating body 8. The decorative cover 18 has a disc-shaped structure with a diameter similar to that of the rotating body 8. The decorative cover 18 is relatively thin to reduce the overall weight. The lower surface of the decorative cover 18 has slots corresponding to the snap-fit ​​protrusions on the rotating body 8. The shape and size of these slots match the snap-fit ​​protrusions to ensure a tight fit. A circular through hole is provided at the center of the decorative cover 18, with a diameter slightly larger than the outer diameter of the locking nut 7, so that the top of the locking nut 7 can be exposed. During installation, the rotating body 8 is first fixed to the output shaft 4 and tightened with the locking nut 7. Then, the decorative cover 18 is aligned with the rotating body 8 so that the slots are aligned with the snap-fit ​​protrusions. Gently press the decorative cover 18 to make the buckle protrusion engage with the slot until a crisp click is heard. At this point, the decorative cover 18 is firmly fixed to the rotating body 8.
