[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] As shown in the figure, a pump station dredging device includes a box body 1, and support plates 2 are provided at the lower part of the inner walls on both sides of the left and right sides of the box body 1, which are inclined downward. The upper ends of the support plates 2 are axially connected to the inner wall of the box body 1, and a grid-shaped flip plate 3 is horizontally overlapped between the lower ends of the two support plates 2, and the flip plate 3 can rotate along the axis in the box body 1. The rear side of each support plate 2 is slidably connected to a telescopic unit 4 horizontally fixed to the side wall of the box body 1. An inlet pipe 101 is provided on one side of the box body 1 above the flip plate 3, and a sewage lifting pump 6 is fixed on the other side. The lower side of the sewage lifting pump 6 is connected to the guide pipe 7 inside the box body 1, and the other side is connected to the outlet pipe 102 on the box body 1. A sewage outlet is provided on one side wall of the box body 1 corresponding to the bottom of the flip plate 3. In this embodiment, sewage enters the box body 1 from the water inlet pipe 101, and then is discharged from the outlet pipe 102 through the sewage lifting pump 6 and the guide pipe 7. The sludge and other impurities in the sewage will be deposited on the support plate 2 and the flip plate 3. Since the support plate 2 is arranged tilted, the sludge and other impurities on the support plate 2 can be easily washed to the upper side of the flip plate 3 by the sewage that continuously enters the box body 1; and for the sludge and other impurities deposited on the flip plate 3, the side of the flip plate 3 where the sludge is deposited can be flipped to face downward every once in a while, and then the sewage that enters the box body 1 can be used to flush the sludge to the upper side of the flip plate 3. The flip plate 3 is flushed, so that the sludge located on the lower side of the flip plate 3 is separated from the flip plate 3 under the action of water and its own gravity, and then the sludge that has fallen on the bottom wall of the box body 1 can be discharged from the sewage outlet; when the flip plate 3 flips, the two support plates 2 are first controlled by the telescopic unit 4 to rotate downward so as to separate from the flip plate 3, that is, to remove the constraint on the flip plate 3, and then the flip plate 3 is rotated until it flips 180° to a horizontal state, and then the two support plates 2 are rotated so that the lower ends abut against the lower side of the flip plate 3 to support the flip plate 3. Of course, since the flip plate 3 has a grid structure, there will be a situation where some sludge leaks from the grid to the bottom wall of the box body 1, but if the grid density of the flip plate 3 is set to be larger, more sludge will accumulate on the flip plate 3.

[0026] The upper ends of the support plates 2 are pivotally connected to the front and rear inner walls of the housing 1 via a rotating shaft 5. Horizontally positioned stop edges 201 are provided at their lower ends, and the flip plate 3 overlaps horizontally above the two stop edges 201. In this embodiment, the stop edges 201, which are integrally formed with the support plates 2, are provided to horizontally support the flip plate 3, preventing it from swinging freely when flipping is not required and effectively limiting its position.

[0027] A slide rail 9 is fixedly attached to the rear side of the support plate 2 along its width. A connecting ring 401 is fixedly attached to the front end of the telescopic unit 4. A slider 10 is slidably inserted within the slide rail 9. Two connecting blocks 1001 are fixedly attached to the side of the slider 10 facing the telescopic unit 4. A connecting shaft 1002 is fixedly connected between the two connecting blocks 1001. The connecting ring 401 is movably sleeved on the connecting shaft 1002. In this embodiment, when the front end of the telescopic unit 4 telescopes, the movable connection between the connecting ring 401 and the connecting shaft 1002 causes the slider 10 to move along the slide rail 9, thereby rotating the support plate 2 along the rotating shaft 5. In this embodiment, the telescopic unit 4 is an electric telescopic rod or a hydraulic cylinder.

[0028] A stopper 105 is fixedly attached to the front and rear inner walls of the box 1, corresponding to the center of each support plate 2. When the flip plate 3 is horizontal and overlapped between the two support plates 2, the front side of the support plate 2 abuts against the stopper 105. In this embodiment, the stopper 105 is provided to limit the upward rotation of the support plate 2, preventing the support plate 2 from flipping upward and preventing the flip plate 3 from being smoothly overlapped between the two support plates 2.

[0029] A rotating column 302 is fixedly connected to the middle of the rear end of the flip plate 3. The rotating column 302 is connected to the rear side wall of the housing 1 via a bearing. A groove 301 is provided in the middle of the front end. A motor is fixedly connected to the outer wall of the housing 1 at a location corresponding to the groove 301. The motor's output shaft passes through the housing 1 and is fixed to the groove 301. In this embodiment, to maximize the deposition of sludge on the upper side via the flip plate 3, the front and rear sides of the flip plate 3 are designed to fit closely to the inner wall of the housing 1. The groove 301 provides a mounting position for the motor's output shaft to be fixed to the flip plate 3.

[0030] The bottom inside the box body 1 is set as an inclined surface 104 to facilitate the discharge and sliding of the washed-down sludge and other debris. A sewage outlet is provided on the side wall of the box body 1 at the lower end of the inclined surface 104, and a sewage pipe 103 is provided at the sewage outlet. A valve is provided on the sewage pipe 103. When it is necessary to clean the sludge at the bottom, the valve is opened to allow the sludge to be flushed out with the water flow. Similarly, a part of the sludge leaked before the flip plate 3 was flipped will also flow with the water, and the more sludge that falls after the flip plate 3 is flipped will be affected by the impact force, so that it will be washed away on the inclined surface 104.

[0031] Universal wheels (not shown) are provided at the four corners of the bottom of the box body 1 for easy movement.

[0032] An end cover 8 is fixedly connected to the top of the box body 1. In this embodiment, a sealing ring is provided between the end cover 8 and the box body 1, and the end cover 8 is fixed to the box body 1 by a plurality of bolts.

[0033] The above description is only a preferred embodiment of the present invention and is 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.
