[0020] Embodiment 1:

[0022] The lower end surface of the connecting plate 106 is fixedly connected with three connecting columns 113 distributed circumferentially along the axis of the connecting plate 106 .

[0023] The lower end of the connecting column 113 is slidably connected with a threaded ring 107 , and the threaded ring 107 is threadedly connected to the inner wall of the threaded arc plate 105 . The rotation of the threaded arc plate 105 can drive the threaded ring 107 to rise and fall.

[0024] The threaded ring 107 is provided with a plurality of elastic cones 108 corresponding to the filter holes 112. The elastic cones 108 are made of elastic material. When the threaded ring 107 moves upward, the elastic cones 108 can enter the filter holes 112, thereby pushing the silt that is blocked in the filter holes 112 to avoid blockage.

[0025] The lower end surface of the threaded ring 107 is fixedly connected to a limiting plate 114 , and the limiting plate 114 can be used for limiting.

[0026] A protection cavity 115 is disposed in the rotating protection cover 104 . A motor 102 is fixedly disposed on the lower end wall of the protection cavity 115 . The motor 102 is motively connected to a motor shaft 103 that is fixedly connected to the rotating protection cover 104 .

[0027] Working principle:

[0028] When in use, the connecting plate 106 is fixedly connected to the water pipe so that the water pipe is connected to the filter chamber 111. At this time, the connecting plate 106 is placed at a position where water needs to be pumped out of the water conservancy project;

[0029] When pumping and filtering, the water pump is started to pump water. When the water flows through the three threaded arc plates 105, large stone impurities are blocked, and the impurities are filtered out through the filtering holes 112 before pumping;

[0030] If the filter hole 112 is blocked, the starting motor 102 drives the motor shaft 103 to rotate, and then drives the rotating protective cover 104 and the threaded arc plate 105 to rotate, and then drives the threaded ring 107 to move upward, and the water pump drains water at the same time. At this time, during the upward movement of the threaded ring 107, the elastic cone 108 passes through the filter hole 112. Combined with the impact of the water flow from the filter chamber 111 on the filter hole 112, the blocked silt or stone can be pushed out of the filter hole 112, and the filter hole 112 is no longer blocked, thereby completing the self-dredging work.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
