Wherein the base 410 is fixedly installed in the sump. The pillar 420 is installed on the top of the base 410 and is fixedly connected with the base 410. The guide shaft 430 is rotatably sleeved on the top of the upright 420. The mounting bracket 440 is rotatably disposed on the guide shaft 430. The upright post 420 is provided with a rotating hole along the length direction thereof, the transmission shaft 450 is rotatably installed in the rotating hole, the bottom end of the transmission shaft 450 is coaxially fixed with the power input shaft 330, the top end of the transmission shaft 450 is fixedly connected with the mounting frame 440, and the axis line of the transmission shaft 450 is overlapped with the rotation center line of the mounting frame 440 and is fixedly connected with the mounting frame 440.
The number of drive paddles 460 is multiple groups of four drive paddles 460. The plurality of sets of driving paddles 460 are sequentially arranged at intervals along the longitudinal direction. The four driving paddles 460 in each group of driving paddles 460 are uniform around the axis 230 of the rotating shaft of the mounting bracket 440, a transmission part 461 is disposed on one side of the driving paddles 460 facing the guide shaft 430, the transmission part 461 is zigzag, and the included angle between the transmission part 461 and the paddle surface of the driving paddles 460 is β, β =45 °.

The guide groove 490 includes a first sub-groove 491, a second sub-groove 492, a third sub-groove 493, and a fourth sub-groove 494, which are connected end to end in sequence. When the transmission part 461 of the driving paddle 460 slides in the first sub-groove 491, the paddle surface of the driving paddle 460 is in a vertical state. When the transmission part 461 of the driving paddle 460 slides in the second sub-groove 492, the paddle surface of the driving paddle 460 forms an inclination angle γ with the horizontal plane. When the transmission part 461 of the driving paddle 460 slides in the third sub-groove 493, the paddle surface of the driving paddle 460 is horizontal.

Thus, in use, when the wind direction is at an angle to the face of the windward plate 470, the angle is assumed to be θ, where 0 ° < θ <180 °. Under the action of the windward plate 470, the windward plate 470 carries the guide shaft 430 to rotate together, so that the windward plate 470 moves to a position where the plate surface is consistent with the wind direction. At this time, the first sub-slot 491 and the third sub-slot 493 extend in the same direction as the wind direction, so that the driving paddles 460 having the paddle planes in the vertical state and the horizontal state are perpendicular to the wind direction, thereby increasing the conversion efficiency to the wind power.
When the wind direction is parallel to the plate surface of the windward plate 470, the windward plate 470 does not rotate with the guide shaft 430. At this time, the extending direction of the first sub-groove 491 and the third sub-groove 493 is the same as the wind direction, the driving paddle 460 having the paddle surface in the vertical state and the horizontal state is perpendicular to the wind direction, the wind force acting on the driving paddle 460 is maximized, and the conversion efficiency of the wind force is maximized.
This structure, the drive oar 460 that keeps the oar face to be in vertical state and horizontality throughout is perpendicular with the wind direction to increased the conversion efficiency to wind-force, and then helped salvaging the operation of mechanism more, thereby the solid waste on the salvage sewage grid that can be better.
In one embodiment, the gear portions 461 of drive paddles 460 of the same side of the plurality of sets of drive paddles 460 are interconnected by a linkage 480.
Thus, in use, the drive paddles 460 on the same side are connected as a unit, such that the drive paddles 460 on the same side are in a linkage relationship with each other.
The working principle of the invention is as follows:
in use, under the action of wind, the wind blows the driving paddle 460 to rotate, so that the driving shaft 450 transmits power to the transmission mechanism 300, and the fishing paddle 220 is driven to rotate to fish the wastes on the sewage grid 100.
