[0029] like Figures 3 to 6As shown, the spindle clamp 5 includes two fixing frames 501 and two supporting electric telescopic rods 507. The bottom ends of the two supporting electric telescopic rods 507 are fixed to the bottom of the cleaning box 1 and are kept perpendicular to the bottom surface of the cleaning box 1. The two fixing frames 501 have three ends. One end of the fixing frame 501 is fixed to the inner wall of the cleaning box 1. The other two ends of the fixing frame 501 are provided with a card slot. The inner side of the card slot is installed with a rotating clamping rod 502. The end of the rotating clamping rod 502 connected to the fixing frame 501 is penetrated and fixed with a mounting shaft rod 503. The mounting shaft rod 503 is fixed to the fixing frame 501. The end of 3 is inserted into the end of the fixing frame 501 and is rotatably connected to the fixing frame 501. A plurality of clamping pneumatic telescopic rods 504 are fixed to the inner circular array of the rotating clamping rod 502. The four rotating clamping rods 502 form a ring after contacting each other. The movable ends of the two supporting electric telescopic rods 507 contact the bottom surfaces of two of the rotating clamping rods 502. The four rotating clamping rods 502 and the clamping pneumatic telescopic rods 504 fixed inside the rotating clamping rods 502 are used to clamp and fix the generator main shaft to ensure that the axis of the generator main shaft is parallel to the ground.

[0030] Fixed rods 505 are fixed on both sides of the ends where the rotating clamping rod 502 is connected to the fixed frame 501, and a rotating guide plate 506 is fixed on the outer surface of the fixed rod 505. The spindle cleaning tool 6 includes two movable sliders 601, and the two movable sliders 601 are respectively penetrated by two transmission screws 10, and the movable sliders 601 and the transmission screw 10 are transmitted by threads. The sides of the two movable sliders 601 facing each other are fixed with movable support rods 602, and a flushing ring 603 is fixed between the two movable support rods 602. When the transmission screw 10 is driven and rotated by the mobile motor 7, the transmission gear 8, and the screw gear 9, the transmission screw 10 causes the movable slider 601, the movable support rod 602 and the flushing ring 603 to move through thread transmission, thereby changing the position of the flushing ring 603.

[0031] like Figure 2 and Figure 3 As shown, a plurality of high-pressure nozzles 604 are distributed in a circular array inside the flushing ring 603, the inner diameter of the flushing ring 603 is larger than the outer diameter of the generator main shaft, a water inlet hose 4 is fixed to the bottom of the flushing ring 603, one end of the water inlet hose 4 passes through the cleaning box 1 and is slidably connected to the cleaning box 1, the end of the water inlet hose 4 passes through the cleaning box 1 and is connected to the water outlet port of the water pump, the water inlet hose 4 and the water pump connected to the water inlet hose 4 are used to extract clean water and send it into the flushing ring 603, and finally the clean water is sprayed at high pressure onto the outer surface of the generator main shaft through the high-pressure nozzle 604 to clean the generator main shaft.

[0032] Contact sliders 605 are fixed on both sides of the end where the movable support rod 602 is connected to the movable slider 601. The end of the contact slider 605 away from the movable support rod 602 is provided with two upper and lower symmetrical inclined surfaces, and the inclination angle of the inclined surfaces is forty-five degrees. The contact slider 605 on the side of the end of the movable support rod 602, when the movable slider 601 moves and approaches the fixed frame 501, the contact slider 605 contacts and squeezes the rotating guide plate 506, so that the rotating guide plate 506 drives the fixed rod 505 and the rotating clamping rod 502 to rotate around the axis of the installation shaft rod 503, so that the four rotating clamping rods 502 that are in contact with each other rotate and open, ensuring that the flushing ring 603 moves smoothly and completes the cleaning of the clamped part of the generator main shaft.

[0033] Working principle: First, place the generator main shaft inside the cleaning box 1, and ensure that the axis of the generator main shaft coincides with the axis of the two main shaft ends clamping the electric telescopic rods 3, turn on the device power, and the two main shaft ends clamp the electric telescopic rods 3. After the end is powered on and started, the end contacts the generator main shaft end, and the generator main shaft is clamped by the two main shaft ends clamping the electric telescopic rods 3. Then, the four rotating clamping rods 502 are rotated around the axis of the mounting shaft rod 503, so that the four rotating clamping rods 502 contact each other, and then the four rotating clamping rods 502 are started. 02, so that the end of the clamping pneumatic telescopic rod 504 contacts the outer surface of the generator main shaft, and the generator main shaft is supported and positioned by using the four rotating clamping rods 502 and the clamping pneumatic telescopic rod 504 inside the rotating clamping rod 502, and the two supporting electric telescopic rods 507 are started, so that the ends of the supporting electric telescopic rods 507 are extended and contact the bottom surfaces of two of the rotating clamping rods 502, and the two supporting electric telescopic rods 507 are used to support the two rotating clamping rods 502 in position;

[0034] Next, the water pump power supply connected to the mobile motor 7 and the water inlet hose 4 is started, and the water pump connected to the water inlet hose 4 draws clean water and sends it into the flushing ring 603 through the water inlet hose 4. After the clean water enters the flushing ring 603, it is sprayed out at high pressure through the high-pressure nozzle 604, and the sprayed clean water is sprayed on the outer surface of the generator main shaft to wash away the stains and impurities on the outer surface of the generator main shaft. At the same time, the mobile motor 7 drives the transmission screw 10 to rotate through the transmission gear 8 and the screw gear 9. When the transmission screw 10 rotates, it drives the moving slider 601, the moving support rod 602, and the flushing ring 603 to move along the axial direction of the transmission screw 10. When moving, the contact slider 605 contacts the rotating guide plate 506;

[0035] Due to the squeezing of the rotating guide plate 506 by the contact slider 605, the rotating guide plate 506, the fixed rod 505, and the rotating clamping rod 502 will rotate around the axis of the mounting shaft rod 503. At this time, the end of the supporting electric telescopic rod 507 located below two of the rotating clamping rods 502 will shrink, ensuring that the rotating clamping rod 502 can be smoothly rotated and opened without affecting the movement of the flushing ring 603 and the cleaning of the generator main shaft. After the flushing ring 603 passes through the rotating clamping rod 502, the end of the supporting electric telescopic rod 507 extends and drives the two rotating clamping rods 502 to rotate and reset. The other two rotating clamping rods 502 will automatically reset under the action of gravity. During the movement, the flushing ring 603 comprehensively cleans the generator main shaft through the high-pressure clean water sprayed by the high-pressure nozzle 604. When the main shaft clamp is used to clean the generator main shaft, the main shaft clamp can be rotated and opened to ensure that the outer surface of the generator main shaft is completely cleaned, shortening the cleaning time and eliminating the need for secondary cleaning, thereby improving the cleaning efficiency.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
