Furthermore, two shaft supports 2 are provided, and the two shaft supports 2 are fixedly mounted in the two ends of the roller mounting groove, providing support for the support shaft 3. The shaft support 2 is in the form of a U-shaped groove. The two ends of the support shaft 3 are fixedly mounted in the grooves of the two shaft supports 2, so that the support shaft 3 is locked circumferentially and axially on the shaft support 2.

[0037] The roller assembly includes a bearing 5 and a roller 6. The bearing 5 is fixedly mounted on one end of the support shaft 3. Two bearings 5 ​​are provided. The two bearings 5 ​​are symmetrically fixedly mounted on both ends of the support shaft 3 to provide support for the roller 6. The roller 6 is in the shape of a hollow double-wall tube. The roller 6 is sleeved outside the support shaft 3 through the center tube thereon, and the two bearing chambers located at the ends of the center tube are fixedly mounted on the outside of the two bearings 5 ​​one by one, so that the roller 6 is axially locked and rotated circumferentially on the bearing 5 axis. Furthermore, reinforcing ribs are provided between the inner and outer walls of the roller 6, and the reinforcing ribs can increase the radial bearing capacity of the roller 6. At the same time, coolant is stored in the roller 6, and the self-cooling component drives the coolant in the roller 6 to circulate self-circulatingly to cool the bearing 5. It should be noted that an adjustment ring is provided outside the bearing chamber.

[0038] The self-cooling component includes a cooling power component, a liquid cooling component, and an air cooling component. The cooling power component is arranged on the rolling support component and the roller component. The liquid cooling component and the air cooling component are both arranged on the cooling power component. The cooling power component includes a cooling protective shell 7, a sealing plate, and a cooling power transmission component. The cooling protective shell 7 is arranged on the roller 6, the sealing plate is arranged on the support shaft 3, and the cooling power transmission component is arranged on the cooling protective shell 7 and the sealing plate. The cooling protective shell 7 is in the shape of a circular groove. The groove of the cooling protective shell 7 is fixedly arranged on one end surface of the roller 6, and the rotating through hole on the bottom surface of the groove of the cooling protective shell 7 is sleeved outside the support shaft 3. This allows the cooling protective shell 7 to rotate as the roller 6 rotates.

[0039] The sealing plate includes a first sealing plate 8, a connecting rod 9, and a second sealing plate 10. The first sealing plate 8 is in the shape of a circular ring. The first sealing plate 8 is fixedly mounted on one end of the support shaft 3 within the cooling protective shell 7. The outer wall of the first sealing plate 8 is rotationally sealed to the inner wall of the cooling protective shell 7. At the same time, one end face of the first sealing plate 8 is rotationally sealed to one end face of the roller 6. Furthermore, a first rotating sealing ring is mounted on the outer wall of the first sealing plate 8, and a second rotating sealing ring is provided on one end face of the first sealing plate 8 to improve the sealing performance of the bearing chamber. One end of the connecting rod 9 is horizontally fixedly mounted on the other end face of the first sealing plate 8, and the three connecting rods 9 are evenly distributed along the circumference. The second sealing plate 10 is in the shape of a circular ring. One side face of the second sealing plate 10 is fixedly mounted on the other end of the three connecting rods 9. The second sealing plate 10 is parallel to the first sealing plate 8. At the same time, the outer wall of the second sealing plate 10 is rotationally sealed to the inner wall of the cooling protective shell 7.

One end of the rotating shaft 15 of the planetary gear 12 is horizontally fixedly mounted on the other end surface of the first sealing plate 8, and the planetary gear 12 meshes with the ring gear 11. Furthermore, three planetary gears 12 are provided, evenly distributed along the circumference. It should be noted that the planetary gears 12 rotate circumferentially on the rotating shaft 15. The power take-off pipe 13 is rotationally sealed and sheathed around the support shaft 3. One end of the power take-off pipe 13 is rotationally sealed and sheathed through the inner ring of the second sealing plate 10 and the rotating through hole, respectively, ensuring a rotationally sealed connection between the power take-off pipe 13, the second sealing plate 10, and the rotating through hole. The sun gear 14 is fixedly sheathed behind the power take-off pipe 13 and meshes with all three planetary gears 12 simultaneously. Furthermore, the power output pipe 13 is sheathed with a fourth rotating sealing ring and the fifth rotating sealing ring.

[0041] It should be noted that when the drum 6 is driven by the anchor chain to rotate, the drum 6 will drive the cooling protective shell 7 to rotate, and then drive the ring gear 11 to rotate. The ring gear 11 drives the sun gear 14 to accelerate rotation through the planetary gear 12, and then provides rotational power to the liquid cooling part and the air cooling part through the power output pipe 13, thereby improving the liquid cooling efficiency and air cooling efficiency of the bearing 5.

[0042] The liquid cooling component includes an impeller 16, a heat dissipation guide plate 17 and a rotating infusion tank 18. The impeller 16 is fixedly mounted on the power output pipe 13 in the water pump chamber to provide power to the coolant in the water pump chamber. The heat dissipation guide plate is in the shape of a rectangular plate. One side of the heat dissipation guide plate is fixedly set on the outer wall of the cooling protective shell 7, and one end of the heat dissipation guide plate 17 is fixedly set on one end surface of the drum 6. Furthermore, an output through-hole 19 is provided in the heat dissipation guide plate 17. One end of the output through-hole 19 is connected to the water pump chamber, and the other end is connected to one end of the drum 6. There are multiple heat dissipation guide plates 17, and the multiple heat dissipation guide plates 17 are evenly distributed around the circumference of the cooling protective shell 7. The rotary infusion groove 18 is in the shape of an annular groove. The bottom of the rotary infusion groove 18 is fixedly embedded in the inner wall of the drum 6, and the bottom surface of the rotary infusion groove 18 is connected to the drum 6 through the first input through-hole 20. The groove opening of the rotary infusion groove 18 is rotationally sealed and sleeved on the support shaft 3, and the groove wall openings on both sides of the rotary infusion groove 18 are rotationally sealed and connected to the outer wall of the support shaft 3. The rotary infusion groove 18 is connected to one end of the second input through-hole 21 in the support shaft 3. The other end of the second input through-hole 21 is connected to the annular groove 22 on the outer wall of one end of the support shaft 3. The annular groove 22 is in the shape of an annulus, and the axis of the annular groove 22 coincides with the axis of the support shaft 3. The annular groove 22 is connected to the third input through-hole 23 on the wall of the power output pipe 13, and the third input through-hole 23 is connected to the water pump chamber. As an option, the second input through hole 21 is distributed in the support shaft 3 in a spiral tube shape to increase the contact area and contact time between the coolant in the second input through hole 21 and the support shaft 3, reduce the temperature of the support shaft 3, and then reduce the inner ring temperature of the bearing 5 through the support shaft 3, and reduce the outer ring temperature of the bearing 5 through the roller 6.

[0043] When the impeller 16 is driven by the power output pipe 13 to rotate, it centrifugally works the coolant within the cooling shield 7, causing the coolant within the cooling shield 7 to enter the drum 6 through the output hole 19. The coolant within the drum 6 then flows through the first input hole 20 into the second input hole 21, then into the annular groove 22 through the second input hole 21. The coolant within the annular groove 22 then flows through the third input hole 23 into the water pump chamber, completing the self-circulation of the coolant. The temperature of the coolant flowing into the output hole 19 is transmitted to the heat dissipation guide plate 17, where it dissipates heat outward. After dissipating the heat, the coolant enters the drum 6, where it neutralizes with the coolant within the drum 6, further cooling it. It then flows back into the second input hole 21 to absorb heat and cool it down.

[0044] The air-cooling element includes blades 24, which are fixedly mounted outside one end of the power output pipe 13 and located between one end of the cooling protective shell 7 and the shaft support 2. When the power output pipe 13 drives the blades 24 to rotate, the rotating blades 24 propel wind to cool the cooling protective shell 7 and the heat dissipation guide plate 17, further improving heat dissipation efficiency.

[0045] Two sets of self-cooling members are provided, and the two sets of self-cooling members are respectively provided at both ends of the rolling support member and the roller member, so as to cool the bearings 5 ​​on both sides one by one by water, thereby improving the reliability of cooling and heat dissipation of the bearings 5 ​​as a whole.

[0046] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
