[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Existing devices use a stirring rod to drive a stirring claw to stir the fixed material raked out by the screen cleaning machine. However, the fixed stirring range of the stirring claw can easily lead to poor results in preventing the fixed material from settling and agglomerating. The main reason is that the fixed range of the stirring claw cannot effectively cope with impurities of different shapes and densities, resulting in uneven stirring effect and sedimentation in some areas. Figure 1-Figure 4 This embodiment provides a pump station rotary screen cleaner, including a connecting plate 1, which is connected to the rotary screen cleaner body through nuts.

[0023] refer to Figure 3 As shown, an ultrasonic water level sensor 4 is fixedly installed at the bottom of the mounting plate 27 for detecting the depth of the water-impurity mixture. The ultrasonic water level sensor 4 detects the depth of the water-impurity mixture by emitting and receiving ultrasonic signals. Specifically, the ultrasonic water level sensor 4 emits high-frequency ultrasonic pulses to the water surface. When the ultrasonic wave encounters the water surface, it will be reflected back to the ultrasonic water level sensor 4. The ultrasonic water level sensor 4 records the time from the emission to the reception of the ultrasonic wave. According to the speed of sound and time, the depth of the water-impurity mixture is calculated using a formula. This method has the advantages of non-contact, accurate and real-time monitoring. The depth result detected by the ultrasonic water level sensor 4 is transmitted to the water surface. To an external controller, the controller controls the rotation amplitude of the rotating component and thus controls the insertion depth of the stirring claw 29, which can improve the stirring effect. By detecting the depth of the water-impurity mixture, the stirring claw 29 can work at the optimal position, thereby enhancing the stirring and mixing effect of solid impurities. The insertion depth of the stirring claw 29 is dynamically adjusted according to the water level change to ensure effective stirring at different depths and prevent solid precipitation. The optimized stirring depth can also cover a larger range, reduce the unstirred area, and improve the overall stirring efficiency. The appropriate depth can also ensure that the stirring claw 29 is in full contact with the water-impurity mixture, thereby achieving a more uniform mixing effect.

[0024] refer to Figure 2-Figure 4As shown, the existing device drives the stirring claw 29 to stir the fixed material raked out by the grille cleaner by rotating the stirring rod. However, the fixed stirring range of the stirring claw 29 can easily lead to a poor effect in preventing the fixed material from sinking to the bottom and agglomerating. The main reason is that the stirring claw 29 with a fixed range cannot effectively cope with impurities of different shapes and densities, resulting in uneven stirring effect, and sedimentation will still occur in some areas. In order to effectively improve the stirring effect and prevent impurities from sinking to the bottom and agglomerating, the following settings are made: an anti-sinking mechanism 2 for stirring the fixed material raked out by the grille cleaner is provided on the top of the connecting plate 1. The anti-sinking mechanism 2 includes two claw rods 28 arranged at the bottom of the connecting plate 1, and the outer walls of the two claw rods 28 A plurality of stirring claws 29 are fixedly installed on each of the connecting plates 1. Two power mechanisms are provided inside the connecting plate 1 to enable the two claw rods 28 to rotate forward and reverse and move up and down simultaneously. The power mechanisms include a threaded rod 25 fixed to the top of the claw rod 28. The outer wall of the threaded rod 25 is threadedly connected to a drive ring 26. The outer wall of the drive ring 26 is fixedly connected to a mounting plate 27. The outer wall of the threaded rod 25 is sleeved with a sleeve 24. A rotating assembly that provides rotational force for the sleeve 24 is provided on the top of the connecting plate 1. The rotating assembly includes a motor 21 fixed to the top of the connecting plate 1. The output end of the motor 21 is fixedly connected to a gear 1 22. The gear 1 22 is meshed with a gear 2 23. The sleeve 24 is fixed to the bottom of the gear 2 23. The interior of the sleeve 24 is provided with a directional assembly that enables the threaded rod 25 to slide in a directional manner along its inner wall. The directional assembly includes a block fixed to the outer wall of the threaded rod 25. The inner wall of the sleeve 24 is provided with a rail groove. The block moves up and down along the height direction of the rail groove. After the user screens out the solid impurities on the rotary screen cleaning machine, the motor 21 is started to drive the output end drive gear 1 22 to rotate forward and reverse. The rotation of gear 1 22 engages with gear 2 23 to drive the sleeve 24 to rotate. This movement can change the direction of the stirring claw 29 and increase the uniformity of stirring. The threaded rod 25 is stuck in the rail groove through the block to ensure that it rotates synchronously with the sleeve 24. At the same time, the threaded connection with the drive ring 26 allows the stirring claw 29 to move up and down. This design enhances the flexibility and adjustability of the stirring claw 29 and can cover a larger stirring range. By moving up and down and rotating forward and backward, the stirring claw 29 can effectively reach more solid impurities, reduce dead angles, and avoid impurity deposition. Through continuous stirring and dynamic adjustment, the solid impurities can be effectively prevented from settling and agglomerating due to long-term standing.

[0025] refer to Figure 2 As shown, the outer wall of the stirring claw 29 is fixedly connected with a conical impact block 3, which is used to reduce the damaging force of the fixed material on the stirring claw 29. The design of the conical impact block 3 can effectively reduce the damaging force of the fixed material on the stirring claw 29. The conical structure helps to disperse the impact force, thereby reducing concentrated stress and reducing the direct impact on the stirring claw 29 when it comes into contact with the fixed material. In addition, it can also guide the flow of materials, reduce friction and wear, and extend the service life of the stirring claw 29.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
