[0022] The driving motor 3 is fixedly connected to the fixed base 2, the output shaft 4 is fixedly connected to the output end of the driving motor 3, the active friction plate 5 is fixedly connected to the output shaft 4, the protective cover 6 is detachably connected to the fixed base 2, and the controller 7 is fixedly connected to the upper surface of the fixed base 2.

[0023] The output shaft 4 passes through and is rotatably connected to the device housing 1. The drive shaft 9 is fixedly connected to the impeller 8. The fixed disk 10 is fixedly connected to the drive shaft 9. The splines 11 are evenly distributed on the outer surface of the drive shaft 9, and the splines 11 are fixedly connected to the drive shaft 9. The driven friction plate 12 is slidably connected to the drive shaft 9. The electric telescopic rods 14 are evenly distributed between the fixed disk 10 and the driven friction plate 12, and both ends of the electric telescopic rods 14 are respectively fixedly connected to the fixed disk 10 and the driven friction plate 12.

[0024] The locking teeth 20 are evenly distributed on the inner surface of the limiting ring 19, and the locking teeth 20 are fixedly connected to the limiting ring 19. The vertical plate 21 is fixedly connected to the fixed bracket 15.

[0025] The locking teeth 20 are evenly distributed on the inner surface of the limiting ring 19, and the locking teeth 20 are fixedly connected to the limiting ring 19. The vertical plate 21 is fixedly connected to the fixed bracket 15, and the locking teeth 20 are meshed with the fixed teeth 18.

[0026] The connecting rod 22 is fixedly connected to the limiting ring 19. The connecting rod 22 passes through and is slidably connected to the vertical plate 21. One end of the telescopic spring 23 is fixedly connected to the vertical plate 21, and the other end of the telescopic spring 23 is fixedly connected to the limiting ring 19.

[0027] Working principle: When using this device, start the drive motor 3. The drive motor 3 drives the output shaft 4 to rotate. The output shaft 4 drives the active friction plate 5 to rotate. The rotation of the active friction plate 5 drives the driven friction plate 12 to rotate through friction. Subsequently, the driven friction plate 12 drives the drive shaft 9 to rotate through the splines 11. The drive shaft 9 drives the impeller 8 to rotate, and the rotation of the impeller 8 generates a forward propulsion force.

[0028] The water flow absorbed by the rotation of the impeller 8 passes through the filter screen 17. The impurities and garbage carried in the water flow are filtered on the outer surface of the filter screen 17. When it is necessary to temporarily stop the operation of the device, the user sends a contraction signal to the electric telescopic rods 14 through the controller 7. After receiving the signal, the electric telescopic rods 14 start to contract. As the electric telescopic rods 14 contract, the electric telescopic rods 14 drive the driven friction plate 12 to slide along the splines 11, separating the driven friction plate 12 from the active friction plate 5, thereby stopping the rotation of the impeller 8. When it is necessary to clean the filter screen 17, the staff can remove the entire device, and then pull down the connecting rod 22. The connecting rod 22 drives the limiting ring 19 to move downward and separate from the fixed teeth 18. At this time, the hinge shaft 16 can rotate normally, and the filter screen 17 flips downward. The staff can use a water gun to wash the filter screen 17. Finally, reset the filter screen 17 and release the connecting rod 22. The connecting rod 22 is re-locked to the hinge shaft 16 under the action of the telescopic spring 23, so that the filter screen 17 will not loosen.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
