Abstract
Description
Technical Field
[0001] This utility model relates to the field of water turbine manufacturing technology, specifically a cleaning device for removing grease from the surface of parts. Background Technology
[0002] In the field of high-end equipment manufacturing, the surfaces of key components such as water turbines and aero engines must be thoroughly cleaned of grease before coating to ensure the bonding strength of the coating. Current technology typically employs manual wiping methods (such as cleaning the surface of parts with a cloth soaked in acetone). This method has significant drawbacks: operators cannot easily reach narrow crevices, blind holes, and curved surface intersections within complex structural components, resulting in grease residue remaining in these hard-to-reach areas. Residual grease will cause a sharp drop in coating bonding strength, localized blistering and peeling, and accelerate the failure of the turbine's flow surfaces under high-pressure water erosion, seriously threatening the operational safety of hydropower stations.
[0003] Based on this, a cleaning device for removing grease from the surface of parts is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0023] In one embodiment, such as Figures 1-6 As shown, a cleaning device for removing grease from the surface of parts includes a workbench 1, an adjusting bracket 2, a clamping mechanism, a lateral adjusting mechanism, and a spraying mechanism. The adjusting bracket 2 is fixedly mounted on the top of the workbench 1, a base 3 is fixedly mounted on the top of the workbench 1, and a sliding bracket 4 is fixedly mounted on the top of the base 3. A clamping mechanism for clamping turbine parts is fixedly mounted on the top of the adjusting bracket 2. An adjusting mechanism for laterally adjusting the spraying position is slidably mounted on the inner wall of the sliding bracket 4. A spraying mechanism for adjusting the spraying angle is fixedly mounted at the bottom of the adjusting mechanism.
[0024] In one embodiment, such as Figure 2As shown, the clamping mechanism includes a mounting plate 5 fixedly mounted on the top of the adjusting bracket 2. A clamping bracket 6 is located on the top of the adjusting bracket 2. First sliders 7 are fixedly mounted at both ends of the clamping bracket 6, and the first sliders 7 are slidably connected to the adjusting bracket 2. A first screw 8 is threadedly connected to the inner wall of the mounting plate 5, and the first screw 8 is rotatably connected to the clamping bracket 6. An adjusting nut is fixedly mounted at the end of the first screw 8 for easy turning by the operator. Turning the adjusting nut with a wrench causes the first screw 8 to rotate, moving it under the action of the thread. Since the first screw 8 is rotatably connected to the clamping bracket 6, it pushes the clamping bracket 6 to move. Because the top of the adjusting bracket 2 has a sliding groove that matches the first slider 7, the clamping bracket 6 slides horizontally on the adjusting bracket 2, allowing the two clamping brackets 6 to align and slidably clamp the turbine unit parts, facilitating subsequent spraying operations. The clamping surface of the clamping bracket 6 has a rubber pad, which can flexibly adapt to the shape of the parts. The clamping bracket 6 can also be quickly disassembled through the sliding connection between the first slider 7 and the sliding groove.
[0025] In one embodiment, such as Figure 3 As shown, the adjustment mechanism includes a second slider 9 slidably disposed on the inner wall of the sliding bracket 4. A second screw 10 is rotatably disposed on the inner wall of the sliding bracket 4. The second slider 9 is threadedly connected to the second screw 10. A mounting bracket 11 is fixedly disposed on the right side of the sliding bracket 4. A first motor 12 is fixedly disposed on the top of the mounting bracket 11. The right end of the second screw 10 is fixedly connected to the output end of the first motor 12. The output end of the first motor 12 drives the second screw 10 to rotate. When the second screw 10 rotates, it drives the second slider 9 to slide laterally on the inner wall of the sliding bracket 4, thereby enabling the second slider 9 to flexibly adjust the spray mechanism laterally.
[0026] In one embodiment, such as Figures 4-6As shown, the spraying mechanism includes a first electric telescopic rod 13 fixedly mounted at the bottom of the second slider 9. An installation platform 14 is fixedly mounted at the output end of the first electric telescopic rod 13. A placement box 15 is fixedly mounted on the top of the installation platform 14. A rotating bracket 16 is rotatably mounted on the top of the placement box 15. A second motor 17 is fixedly mounted on the top of the rotating bracket 16. The output end of the second motor 17 is fixedly connected to the bottom end of the rotating bracket 16. A fixing rod 18 is rotatably mounted on the inner wall of the rotating bracket 16. A guide rod 19 is fixedly mounted on the right end of the fixing rod 18. A second electric telescopic rod 20 is fixedly mounted on the top of the installation platform 14. A guide bracket 21 adapted to the guide rod 19 is fixedly mounted at the output end of the second electric telescopic rod 20. A vortex drive assembly for expanding the spraying range is fixedly mounted on the top of the fixing rod 18. A guide ball is fixedly provided at the end of the guide rod 19. A guide groove adapted to the guide ball is opened on the inner wall of the guide bracket 21. The guide rod 19 is specifically a driven telescopic rod, which can be extended and retracted according to the position of the guide ball when sliding in the guide groove, so as to prevent the guide rod 19 from falling off the guide bracket 21. The second motor 17 is fixedly installed inside the placement box 15. The output end of the second motor 17 drives the rotating bracket 16 on the placement box 15 to rotate, so that the rotating bracket 16 drives the fixed rod 18 to rotate and adjust. At this time, the guide rod 19 at the end of the fixed rod 18 slides in the guide groove of the guide bracket 21. Then, the second electric telescopic rod 20 is controlled to push the guide bracket 21 to adjust the height. The guide rod 19 rotates under the movement of the guide bracket 21 and drives the fixed rod 18 to rotate, so that the fixed rod 18 drives the vortex guide cone 22 to flexibly adjust the spray angle. By setting the first electric telescopic rod 13, the entire spray mechanism can be vertically adjusted to reach the cleaning area.
[0027] The vortex drive assembly includes a vortex guide cone 22 fixedly mounted on the top of a fixed rod 18. The bottom of the vortex guide cone 22 is connected to a water inlet 23. A spiral guide vane 24 is fixedly mounted on the inner wall of the vortex guide cone 22. A rotating nozzle 25 is rotatably mounted on the top of the vortex guide cone 22, and a vortex drive groove is formed at the end of the rotating nozzle 25. Water is introduced through a flexible hose from the water inlet 23. The water flow, guided by the spiral guide vane 24 in the vortex guide cone 22, forms a vortex. When sprayed out through the rotating nozzle 25, the vortex drive groove on the rotating nozzle 25 drives the rotating nozzle 25 to rotate under the action of the rotating water flow, thereby forming a wide-range high-pressure water flow. By coordinating with the adjustment of height and angle, it can precisely clean the dead corners of parts, improving cleaning efficiency and quality, and bringing convenience to operators.
[0028] The above embodiment discloses a cleaning device for removing grease from the surface of parts. The operator rotates a first screw 8 using a tool, driving a clamping bracket 6, which is rotatably connected to the first screw 8, to move horizontally along an adjusting bracket 2. The first sliders 7 at both ends of the clamping bracket 6 slide synchronously within the sliding grooves of the adjusting bracket 2, causing the two clamping brackets 6 to move in opposite directions, thereby clamping and fixing the turbine generator parts and providing a stable positioning basis for subsequent spraying. The first motor 12 drives the second screw 10 to rotate, causing the threaded second slider 9 to move laterally within the sliding bracket 4, thus adjusting the horizontal position of the spray mechanism. The first electric telescopic rod 13 at the bottom of the second slider 9 controls the vertical height of the mounting platform 14, allowing the spray mechanism to reach the cleaning area directly. Simultaneously, the second motor 17 drives the rotating bracket 16 to rotate, causing the fixed rod 18 and the vortex guide cone 22 to rotate as a whole; the second electric telescopic rod 20 pushes the guide bracket 21, and through the sliding of the guide ball at the end of the guide rod 19 in the guide groove, further adjusts the pitch angle of the fixed rod 18, achieving precise control of the spray direction. Water flows into the vortex guide cone 22 from the inlet 23, and through the spiral guide vane 24, forms a vortex that drives the rotating nozzle 25 to rotate, expanding the coverage of the high-pressure water flow and thoroughly cleaning the dead corners of the parts.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
