[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 and 2As shown, a rapid cleaning device for a water supply filter in a hydropower station includes a telescopic mechanism 2 that cooperates with the output end of a rotary motor 1. The housing of the telescopic mechanism 2 is fixedly connected to the center of a distribution plate 3. A fixing block 4 is provided on the outer edge of the distribution plate 3. The telescopic rod of the telescopic mechanism 2 is fixedly connected to the center of a push plate 5. The outer edge of the push plate 5 is hinged to one end of a crank arm 6. The inflection point of the crank arm 6 is hinged to the fixing block 4. The other end of the crank arm 6 is hinged to one end of a push rod 7. The middle part of the push rod 7 is hinged to one end of a connecting rod 8. The other end of the connecting rod 8 is hinged to the fixing block 4. The other end of the push rod 7 is fixedly connected to a push plate 9. A cleaning plate 10 is provided on the outer side of the push plate 9. The cleaning plate 10 cooperates with the inner wall of the filter cylinder. In this embodiment, when the telescopic rod of the telescopic mechanism 2 extends, it can drive the push plate 5 to move downward, thereby causing one end of the crank arm 6 to rotate, which in turn causes the other end of the crank arm 6 to rotate and drive the push rod 7 to move outward. Ultimately, this allows the push plate 9 and cleaning plate 10 to unfold outward. During this process, the connecting rod 8 rotates accordingly, stabilizing the outward unfolding process. Conversely, when the telescopic rod of the telescopic mechanism 2 retracts, it can drive the push plate 5 to move upward, thereby causing one end of the crank arm 6 to rotate, which in turn causes the other end of the crank arm 6 to rotate and drive the push rod 7 to move inward. Ultimately, this allows the push plate 9 and cleaning plate 10 to retract inward. During this process, the connecting rod 8 rotates accordingly, stabilizing the inward retraction process. The above process is designed to accommodate water filter cylinders with different inner diameters, achieving precise cleaning. More preferably, to make the entire mechanism operate more smoothly, two crank arms 6 can be hinged on the outer edge of the push plate 5, and there are also two corresponding push rods 7 and connecting rods 8, which can increase the stability of the movement of the push plate 9 and cleaning plate 10.

[0022] Preferably, the output shaft of the rotary motor 1 is fixedly connected to the top of the telescopic mechanism 2, and the outer side of the output shaft of the rotary motor (1) is fixedly connected to the inner ring of the bearing 11. The outer ring of the bearing 11 is connected to the top of the vertical rod 14 through the connecting rod 13, and the bottom of the vertical rod 14 is provided with a pressure plate 15. With this design, by contacting the top of the filter cylinder with the pressure plate 15, and then using the vertical rod 14, the connecting rod 13 and the bearing 11 as support, the entire cleaning device is installed on the cylinder. In this embodiment, the bearing 11 is a deep groove ball bearing. The cleaning device involved in this application is relatively light, and the bearing 11 can axially support its weight without affecting the rotation process of the output shaft of the rotary motor 1.

[0023] Preferably, the outer edge of the distribution disk 3 has three fixed blocks 4 evenly distributed in a ring array.

[0024] Preferably, the outer edge of the push plate 5 is evenly hinged with three crank arms 6 in a ring array.

[0025] The above technical solution allows the three cleaning plates 10 to unfold outwards and fit tightly together, resulting in more even force distribution and a more stable rotation cleaning process.

[0026] Preferably, the telescopic mechanism 2 is a hydraulic telescopic rod structure, a pneumatic telescopic rod structure, or an electric push rod structure.

[0027] Preferably, the outer side of the push plate 9 is detachably connected to the cleaning plate 10. This design facilitates the replacement of different types of cleaning plates 10 as needed. Preferably, the surface of the cleaning plate 10 is a sponge, fiber cloth, or nylon brush structure. This design allows for the selection of the appropriate cleaning plate 10 based on the impurities inside the water filter cylinder to be cleaned. For example, if there is a lot of mud and sand, a cleaning plate 10 with a nylon brush can be selected for initial cleaning, followed by a cleaning plate 10 with a sponge for further cleaning, and finally, a cleaning plate 10 with a fiber cloth can be used to wipe away the water stains.

[0028] Preferably, the center of the distribution plate 3 is welded to the bottom of the mounting cylinder 12, and the housing of the telescopic mechanism 2 is fitted with the mounting cylinder 12. The distribution plate 3 can be stably installed using the mounting cylinder 12.

[0029] Preferably, the shell surface of the telescopic mechanism 2 is cylindrical, and the mounting cylinder 12 is an annular cylindrical structure. With this design, if the cleaning plate 10 cannot rotate inside the filter cylinder due to unforeseen circumstances (e.g., impurities obstructing its rotation), the telescopic mechanism 2 and the mounting cylinder 12 will rotate relative to each other because the shell surface of the telescopic mechanism 2 is cylindrical and the mounting cylinder 12 is an annular cylindrical structure. This prevents the rotary motor 1 from burning out due to the cleaning plate 10 being stuck.

[0030] Preferably, the telescopic rod of the telescopic mechanism 2 is fixedly connected to the center of the push plate 5 by bolts.

[0031] Preferably, the surface of the cleaning plate 10 is an arc-shaped structure that conforms to the inner wall of the filter cylinder. This design allows the surface of the cleaning plate 10 to fit tightly against the inner wall of the cylinder.

[0032] The working principle of this embodiment is as follows: First, based on the dimensions of the water filter cylinder, the telescopic length of the telescopic mechanism 2 is adjusted to allow the push plate 9 and cleaning plate 10 to extend outwards or retract inwards. This allows the push plate 9 and cleaning plate 10 of the entire cleaning device to extend into the water filter cylinder. During this process, the pressure plate 15 contacts the top of the water filter cylinder, and the entire cleaning device is installed onto the cylinder using the vertical rod 14, connecting rod 13, and bearing 11 as supports. Then, the telescopic mechanism 2 is activated, extending its telescopic rod, which moves the push plate 5 downwards, thereby allowing one end of the crank arm 6 to... The rotation causes the other end of the crank arm 6 to rotate, which in turn drives the push rod 7 to move outward. This allows the push plate 9 and the cleaning plate 10 to unfold outward until the cleaning plate 10 is in close contact with the inner wall of the filter cylinder. Finally, the rotary motor 1 is turned on, causing the telescopic mechanism 2, the distribution plate 3, the fixing block 4, the push plate 5, the crank arm 6, the push rod 7, the connecting rod 8, the push plate 9, and the cleaning plate 10 to rotate together. When the cleaning plate 10 rotates, it can clean the inner wall of the filter cylinder, sweeping or agitating the impurities adhering to the inner wall of the cylinder. After the above process is completed, it can be rinsed with clean water.

[0033] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
