[0058] The two working boxes 102 are both provided with a filter assembly 3 and a driving mechanism 4 .

[0059] The filter assembly 3 includes four L-shaped pressure plates 301 located in the working box 102 and distributed in a circular array. Plane pressure plates 302 are movably connected on both sides of the L-shaped pressure plate 301. The L-shaped pressure plate 301 and the planar pressure plate 302 are both hollow and interconnected. A spring 1 303 is fixed between the L-shaped pressure plate 301 and the two planar pressure plates 302 respectively. By setting the spring 1 303, one side of the planar pressure plate 302 can always be against the inner wall of the working box 102. A spring 2 304 is fixedly installed between the L-shaped pressure plate 301 and the working box 102. The four springs 2 304 in each working box 102 are all inclined and distributed on the diagonal of the working box 102.

[0065] Example 3 further optimizes the environmentally friendly dredging device for water damage projects provided in Example 1 or 2. For details, please refer to Figure 6 A limiting component 5 is arranged outside the processing box 1 .

[0067] When the limiting rod 507 is in the limiting groove 503 , the limiting groove 503 can limit the limiting rod 507 and the threaded rod 406 so that they cannot rotate and can only move horizontally.

[0068] The sleeve 502 is provided with two symmetrically distributed installation grooves 504 on one side close to the limiting groove 503, a spring 3 505 is fixedly connected in the installation groove 504, and a sloped limiting block 506 extending to the outside of the sleeve 502 is fixedly installed at the free end of the spring 3 505;

[0069] When the limiting rod 507 is located outside the limiting groove 503 and is in the same plane as any inclined limiting block 506 , the inclined limiting block 506 can limit the threaded rod 406 and the limiting rod 507 so that they can only rotate in one direction.

[0070] Example 4: The environmentally friendly dredging device for water damage engineering provided in the above embodiments is further optimized. Please refer to Figure 7-Figure 9 A water delivery mechanism 6 is provided outside the processing box 1 .

[0071] The water delivery mechanism 6 includes circular sleeves 601 rotatably connected to the left and right side walls of the treatment box 1 and symmetrically distributed in pairs, the moving wheels 2 are sleeved on the circular sleeves 601, and each of the circular sleeves 601 is provided with an outer annular square tube 602 and an inner annular square tube 603 on the outside, and a retractable water suction pipe 604 interconnected with the inside of the outer annular square tube 602 is installed on the surface of the outer annular square tube 602, and the retractable water suction pipe 604 extends to the inside of the working box 102;

[0072] A retractable water outlet pipe 605 is fixedly installed on the surface of the inner annular square tube 603 and is interconnected with the interior thereof. The free end of the retractable water outlet pipe 605 is fixed on the side wall of the treatment box 1 and is interconnected with the water storage tank 103.

[0073] Two pipes 1 608 are fixedly installed between the outer annular square tube 602 and the circular sleeve 601, and one-way water inlet valves 609 are installed on the two pipes 1 608;

[0074] Two pipes 6010 are fixedly installed between the inner annular square tube 603 and the circular sleeve 601, and one-way water outlet valves 6011 are installed on the two pipes 6010;

[0075] The side walls of the outer annular square tube 602 and the inner annular square tube 603 close to the circular sleeve 601 are rotatably connected to the main body thereof;

[0076] When the circular sleeve 601 rotates, it can drive a side wall of the outer annular square tube 602 and the inner annular square tube 603 to rotate through the pipe 1 608 and the pipe 2 6010, and the main bodies of the outer annular square tube 602 and the inner annular square tube 603 remain stationary.

[0077] An annular platform 6012 is integrally fixed in the circular sleeve 601, and four equally spaced extension plates 6013 and a partition plate 6014 located between two of the extension plates 6013 are integrally fixed to the inner wall of the annular platform 6012. A sector plate 6015 is fixed between every two brackets on the cross drive plate 407, and an annular sleeve 6016 rotatably connected to the four sector plates 6015 is sleeved on the surface of the one-way water outlet valve 6011. A through hole 6017 for the threaded rod 406 to pass through is opened on the surface of the one-way water outlet valve 6011;

[0078] When the annular sleeve 6016 is attached to the annular platform 6012, the sector plate 6015 and the cross drive plate 407 block the inside of the circular sleeve 601 into four closed spaces, and the partition plate 6014 divides one of the spaces into two again;

[0080] An electric push rod 7 is fixed to the left and right side walls of the processing box 1, and a plurality of transverse wheels 8 are rotatably connected to the moving wheel 2;

[0081] By setting an electric push rod 7, it is convenient to drive the two side walls of the processing box 1 to move in opposite directions, so that the processing box 1 is opened for unloading, and the transverse wheel 8 can not only reduce the friction between the moving wheel 2 and the ground when it moves horizontally, but also increase the friction between the moving wheel 2 and the road surface when it rolls, thereby preventing the road surface from slipping due to too much silt.

[0082] The use process of the environmentally friendly dredging device for water damage projects provided by the present invention is as follows:

[0083] When the limiting rod 507 and the outermost inclined limiting block 506 are in the same plane, the cross driving plate 407 and the cross sleeve 408 are in a state of being away from each other;

[0084] At this time, the external motor is started to drive the second gear 405 to rotate, and the second gear 405 can drive the gear 1 404 meshing with it to rotate accordingly, and the gear 1 404 can drive the internal thread sleeve 403 to rotate accordingly, and the internal thread sleeve 403 can drive the threaded rod 406 and the cross driving plate 407 to rotate accordingly, and the cross driving plate 407 can push the inclined surface of the inclined surface limiting block 506 during rotation, so that the inclined surface limiting block 506 is retracted into the installation groove 504, and the inclined surface limiting block 506 will not restrict the limiting rod 507, and at the same time, the threaded rod 406 can drive the cross driving plate 407 fixed at one end thereof to rotate accordingly, and the cross driving plate 407 can drive the circular sleeve 601 to rotate accordingly through the extension plate 6013, and the circular sleeve 601 can drive the moving wheel 2 to rotate, so that the device as a whole is in a moving state;

[0085] The sludge is scooped up and transported to the feed port 105 by an external conveyor belt, and enters the working box 102 through the flow slot 104 and the feed port 106;

[0086] At the same time, the annular sleeve 6016 and the annular platform 6012 are in a tightly fitted state, the sector plate 6015 and the cross drive plate 407 block the inside of the circular sleeve 601 into four closed spaces, and the partition plate 6014 divides one of the spaces into two again;

[0087] When the cross driving plate 407 is driven to rotate back and forth, the enclosed space on both sides of the partition 6014 will be squeezed repeatedly, forming a piston movement, and the sewage filtered out of the working box 102 is sucked into the enclosed space on both sides of the partition 6014 through the telescopic water suction pipe 604, the outer annular square pipe 602 and the pipe 1 608, and then the sewage is transported to the water storage tank 103 for storage through the pipe 2 6010, the inner annular square pipe 603 and the telescopic water outlet pipe 605;

[0088] When the external motor drives the gear 2 405 to rotate in the opposite direction, the threaded rod 406 and the limiting rod 507 also rotate in the opposite direction. When the limiting rod 507 is limited by the plane side of the inclined limiting block 506, the threaded rod 406 and the limiting rod 507 cannot continue to rotate and move along the limiting groove 503 to the other side of the inclined limiting block 506. When the limiting rod 507 and the threaded rod 406 move to the other inclined limiting block 506, the threaded rod 406 also drives the cross driving plate 407 to separate from the extension plate 6013, and the cross driving plate 407 is stuck in the cross sleeve 408.

[0089] At this time, the cross drive plate 407 rotates forward again, driving the cross sleeve 408 to rotate accordingly. The cross sleeve 408 can drive the cross 306 and the inclined push block 307 to rotate accordingly. During the rotation, the inclined side of the inclined push block 307 can push the L-shaped pressure plate 301 to continuously move toward the corner of the working box 102, thereby squeezing the sludge that enters the working box 102 only through the feed port 106, filtering out the moisture in the sludge, flowing out through the water outlet trough 305, temporarily stored in the working box 102, and then transported to the water storage tank 103.
