Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy and hydropower engineering, and in particular to a dam cleaning device for water conservancy and hydropower engineering. Background Technology
[0002] Dams in water conservancy and hydropower projects are prone to the accumulation and deposition of various types of dirt. This dirt not only affects the appearance of the dam, but long-term accumulation may also cause erosion of the dam material, accelerate aging, and even affect the operational safety of the dam. Therefore, dam cleaning devices for water conservancy and hydropower projects are one of the important measures to ensure the long-term safe and stable operation of dams.
[0003] However, this device still has some problems in its use. For example, the cleaning brushes of existing devices are usually fixedly connected to the main body or power system. This makes it easy for debris, silt, or chemical substances to get tangled on the surface or inside of the brushes after a period of use, resulting in a decrease in the cleaning effect. However, due to the inconvenience of disassembly, maintenance personnel often need to spend a lot of time and effort, and even use special tools to remove the brushes from the device for cleaning or replacement, which also affects the continuity and efficiency of the cleaning operation. At the same time, most existing dam cleaning devices have a fixed working angle for their cleaning brushes. This invariability of the angle greatly limits the adaptability and flexibility of the device, because brushes with a fixed angle may not be able to effectively contact all surfaces that need to be cleaned, resulting in incomplete cleaning. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dam cleaning device for water conservancy and hydropower projects. Through the locking component, users can quickly disassemble and replace the cleaning brush according to their needs, which greatly shortens the time required to replace or clean the brush.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dam cleaning device for water conservancy and hydropower projects, comprising a cleaning box, a storage tank fixedly connected to the inner wall of the cleaning box, a flexible hose fixedly connected to the inner wall of the storage tank, a base plate fixedly connected to the bottom end of the flexible hose, connecting pipes fixedly connected to both sides of the base plate, a rotating plate fixedly connected to the outer wall of the connecting pipe, a motor fixedly connected to the top end of the rotating plate, a driving end of the motor penetrating the rotating plate and fixedly connected to a rotating column, a locking assembly provided on the inner wall of the rotating column, the rotating column fixing the cleaning brush relatively by the locking assembly, chucks clamped on both sides of the rotating plate, and the outer wall of the chucks fixedly connected to the rear end of the outer wall of the cleaning box.
[0006] Furthermore, the positioning assembly includes an inner tube fixedly connected to the inner wall of the rotating column, a compression spring fixedly connected to the inner wall of the inner tube, and locking members fixedly connected to both sides of the compression spring. A cleaning brush is fixedly attached to the bottom end of the locking member, and the cleaning brush is used to clean the dam.
[0007] Furthermore, a second gear is fixedly connected to the outer wall of the rotating column, a first gear is meshed with the outer wall of the second gear, and another rotating column is fixedly connected to the inner wall of the first gear.
[0008] Furthermore, a cleaning brush is provided at the bottom end of the connecting tube, and the connecting tube is used to spray water onto the cleaning brush.
[0009] Furthermore, a pressure pump is fixedly connected to the outer wall of the hose. The pressure pump is used to extract and pressurize the water in the hose. The bottom end of the pressure pump is fixedly connected to the top of the cleaning tank.
[0010] Furthermore, a round tube is fixedly connected to the inner wall of the chuck, a tension spring is fixedly connected to the inner wall of the round tube, and a rod is fixedly connected to the outer wall of the tension spring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-4This utility model provides an embodiment of a dam cleaning device for water conservancy and hydropower projects, comprising a cleaning tank 1, a storage tank 2 fixedly connected to the inner wall of the cleaning tank 1, a feed inlet 3 fixedly connected to the top of the storage tank 2, a cap 4 threadedly connected to the outer wall of the feed inlet 3 for protection of the feed inlet 3, a hose 5 fixedly connected to the inner wall of the storage tank 2, a pressure pump 12 fixedly connected to the outer wall of the hose 5 for pressurizing the water in the hose 5, the bottom end of the pressure pump 12 fixedly connected to the top of the cleaning tank 1, a base plate 6 fixedly connected to the bottom end of the hose 5, connecting pipes fixedly connected to both sides of the base plate 6, a cleaning brush 14 corresponding to the bottom end of the connecting pipe, the connecting pipe for spraying water onto the cleaning brush 14, and the outer wall of the connecting pipe... A rotating plate 7 is fixedly connected, and a motor 8 is fixedly connected to the top of the rotating plate 7. The drive end of the motor 8 passes through the rotating plate 7 and is fixedly connected to a rotating column 13. A locking assembly is provided on the inner wall of the rotating column 13. A second gear 17 is fixedly connected to the outer wall of the rotating column 13. A first gear 16 is meshed with the outer wall of the second gear 17. Another rotating column 13 is fixedly connected to the inner wall of the first gear 16. The rotating column 13 fixes the cleaning brush 14 relatively by the locking assembly. The locking assembly includes an inner tube 19 fixedly connected to the inner wall of the rotating column 13. A compression spring 20 is fixedly connected to the inner wall of the inner tube 19. A locking piece 15 is fixedly connected to both the left and right sides of the compression spring 20. The bottom end of the locking piece 15 is fitted with the cleaning brush 14. The cleaning brush 14 is used to clean the dam.
[0024] Specifically, the operator rotates and removes the cap 4, detaching it from the inlet 3. Then, the prepared cleaning solution or water can be poured smoothly into the storage tank 2 through the inlet 3. After the required amount of cleaning solution has been added, the cap 4 is tightened again to seal and prevent leakage or impurities from entering. Next, the pressure pump 12 is started, drawing water or cleaning solution from the storage tank 2 through the connected hose 5. This pressurized liquid is then evenly sprayed onto the cleaning brush 14 through the connecting pipe on the base plate 6, moistening and softening the dirt and assisting in cleaning. Once everything is ready, the operator starts the motor 8, causing the internal rotating column 13 to rotate at high speed, directly driving the cleaning brush 14 for efficient scrubbing. Simultaneously, the rotation of the rotating column 13, through the meshing of the second gear 17 and the first gear 16 on its outer wall, drives another rotating column 13 to rotate synchronously in the opposite or same direction. The two cleaning brushes 14 work together to clean the dam surface more comprehensively and thoroughly from different directions. Combined with the sprayed water flow, they effectively remove various attachments and dirt. During long-term use, the cleaning brushes 14, as vulnerable parts that directly contact the dam surface, may require regular maintenance, inspection, or replacement. When maintenance or replacement of the cleaning brushes 14 is required, the operator simply presses the clip 15 located at the installation point of the cleaning brushes 14. Under pressure, the clip 15 moves inward and compresses the internal spring 20. This action causes the locking structure at the bottom of the clip 15 to disengage from the corresponding slot or positioning surface of the cleaning brush 14, thereby releasing the fixation restriction on the cleaning brush 14. At this time, the cleaning brush 14 can be easily removed from the device for replacement or maintenance. After replacing the cleaning brush 14, the clip 15 is released. Under the elastic force of the spring 20, the clip 15 will reset, and its bottom end will re-lock into the new cleaning brush 14, completing the quick installation.
[0025] Reference Figure 3 and Figure 5 The rotating plate 7 has chucks 9 on both the left and right sides. The outer wall of the chuck 9 is fixedly connected to the rear end of the outer wall of the cleaning box 1. The inner wall of the chuck 9 is fixedly connected to a round tube 11. The inner wall of the round tube 11 is fixedly connected to a tension spring 18. The outer wall of the tension spring 18 is fixedly connected to a rod 10. The outer wall of the chuck 9 has several slots. The size of the rod 10 is adapted to the slots. The rod 10 is used to insert into the rotating plate 7. The front end of the rotating plate 7 is fixedly connected to the left and right sides. The front end of the hinge is rotatably connected to the top of the cleaning box 1.
[0026] Specifically, the operator observes the specific angle changes of the dam profile and then pulls the insert rod 10 on the device outward to smoothly pull it out of the corresponding hole in the rotating plate 7. This action not only releases the fixed restriction on the rotating plate 7, allowing it to rotate freely, but also, due to the movement of the insert rod 10, it also stretches the internal tension spring 18. Next, the operator rotates the rotating plate 7 to adjust the angle of the cleaning brush 14 connected to it, so that it can perfectly adapt to the current angle of the dam profile, ensuring that the brush head can contact the dam surface in the most effective posture during subsequent cleaning. Then, after adjusting to the ideal angle, the operator only needs to release the pulling force on the insert rod 10. At this time, the stretched tension spring 18 will quickly release its stored elasticity, automatically pushing the insert rod 10 forward and firmly re-inserting it into the rotating plate 7, thereby accurately locking the new position of the cleaning brush 14 and ensuring that its angle remains stable during operation.
[0027] Working principle: When the dam of a water conservancy and hydropower project needs to be cleaned, the cleaning device is first moved to the surface of the dam. Then, according to the angle of the dam profile, the insert rod 10 is pulled outward to remove it from the rotating plate 7, thereby releasing the restriction on the rotating plate 7 and stretching the tension spring 18. Then the rotating plate 7 can be rotated to adjust the angle of the cleaning device. After the adjustment is completed, the insert rod 10 is released, and the elastic force of the tension spring 18 will push the insert rod 10 back into the rotating plate 7, thereby fixing the position of the cleaning brush 14.
[0028] Then rotate the cap 4 to detach it from the inlet 3, and pour the cleaning solution or water into the storage tank 2 through the inlet 3. After adding the solution, return the cap 4 to its original position and start the pressure pump 12. The pressure pump 12 will draw water from the storage tank 2 through the hose 5 and spray it onto the cleaning brush 14 through the base plate 6. Then start the motor 8 to drive the rotating column 13 to rotate. The rotation of the outer wall of the rotating column 13 will drive the second gear 17 to rotate. The rotation of the second gear 17 will drive the first gear 16 to rotate. When the rotating column 13 rotates, it will drive the other rotating column 13 to rotate synchronously, so that the two cleaning brushes 14 can work with the water to clean the dam surface. When the cleaning brush 14 needs to be maintained or replaced, press the clip 15 to squeeze the spring 20 inward, and at the same time, the bottom end of the clip 15 will leave the cleaning brush 14 to release the restriction on the cleaning brush 14. Then the cleaning brush 14 can be replaced.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
