[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 12As shown in the figure, a towed drainage vehicle for piling objects includes: a tractor 1, a carriage 101 and a support base 102; it also includes: a placement part 2, arranged on the support base 102 to place the equipment required for drainage; a pump water tank 3, arranged on the support base 102 to pump and drain water; a partition 103, arranged on the support base 102 and connected to the inner wall of the carriage 101, and located between the placement part 2 and the pump water tank 3 to separate the placement part 2 and the pump water tank 3; a filtering part 4, arranged on the support base 102 and inside the pump water tank 3; the filtering part 4 includes: a filtering box body 402, arranged on the support base 102; an intermittent filtering assembly, arranged inside the filtering box body 402 to perform non-blocking filtration on the water body to ensure smooth water flow; an external cleaning part, arranged on the inner wall of the filtering box body 402 and acting on the intermittent filtering assembly to clean the outer surface of the intermittent filtering assembly; a filter bucket 801, arranged inside the filtering box body 402 and inside the intermittent filtering assembly to load the water flow filtered by the intermittent filtering assembly; an internal cleaning part, arranged on the filter bucket 801 and acting on the inner wall of the intermittent filtering assembly to clean the inner wall of the intermittent filtering assembly; a water pump 5, arranged on the support base 102 and connected to the filtering part 4; a water flow detection part, arranged on the filtering part 4 to check the water flow during pumping to adjust the filtering rate.

[0021] In the embodiment of the present invention, by providing the placement part 2 with an inlet and outlet 201, it is convenient to place the equipment required for disaster relief; by providing the filtering part 4, after filtering the pumped water, it then passes through the water pump 5 and is discharged from the drain pipe 501; an intermittent filtering assembly is provided. When filtering, the garbage stays outside the annular filter screen 701, and at the same time, the annular filter screen 701 is rotated to make the garbage fall downward. At the same time, the annular filter screen 701 that rotates and contacts the water flow has no garbage, thus avoiding the blockage of the filter holes by garbage; at the same time, an internal cleaning part and an external cleaning part are provided to clean the annular filter screen 701 to avoid the blockage of the mesh holes; a water flow detection part is provided to judge the flow rate of the water flow, thereby judging the blockage condition of the mesh holes and adjusting the rotation speed of the annular filter screen 701.

[0022] As Figures 4 to 8As shown, the filtering part 4 further includes: a water inlet tank 302 opened on the carriage 101; a water inlet pipe 401, one end of which is connected to the water inlet tank 302 and the other end of which is connected to the top end of the filtering box body 402; a water inlet frame 403, the top end of which is connected to the filtering box body 402; an arc-shaped plate 404, connected to the bottom end of the water inlet frame 403 and fittingly connected to the intermittent filtering assembly; a support limiting shaft 803, one end of which is connected to the inner wall of the filtering box body 402 and the other end of which passes through the intermittent filtering assembly and is connected to the filter water bucket 801 to support the filter water bucket 801 and the intermittent filtering assembly; a first water delivery pipe 804, one end of which passes through the filtering box body 402 and is connected to the filter water bucket 801 and the other end of which is connected to the water flow detection part; a second water delivery pipe 805, one end of which is communicated with the bottom end of the first water delivery pipe 804 and the other end of which is connected to the water pump 5.

[0023] In the embodiment of the present invention, a water inlet hose is provided to pass through the water inlet tank 302 and the water inlet pipe 401 for connection. Water flows in from the water inlet hose, flows into the filtering box body 402 through the water inlet pipe 401, then enters the filter water bucket 801 through the intermittent filtering assembly, and then enters the water pump 5 from the filter water bucket 801 through the first water delivery pipe 804 and the second water delivery pipe 805, and finally is discharged from the provided drain pipe 501, thus completing the pumping and drainage operations of the drainage vehicle.

[0024] As Figures 4 to 9 shown, the intermittent filtering assembly includes: a support circular plate 703 sleeved on the support limiting shaft 803 and fittingly connected to the bottom end of the arc-shaped plate 404; an outer ring seat 704, one end of which is fixedly connected to the support circular plate 703 and fittingly connected to the bottom end of the arc-shaped plate 404; an annular filter screen 701 arranged on the outer ring seat 704 to filter water flow; a plurality of groups of filter limiting plates 702, both ends of the plurality of groups of filter limiting plates 702 being connected to the outer ring seat 704 to divide the annular filter screen 701 into several filtering spaces; an intermittent driving member connected to the support circular plate 703 to drive the support circular plate 703 to rotate intermittently.

[0025] As Figures 4 to 9 shown, the intermittent driving member includes: a rotation limiting block 706 sleeved on the support limiting shaft 803; a special-shaped convex block 705 limit-connected to the rotation limiting block 706; and a motor 707 arranged on the inner wall of the filtering box body 402, and the output end of the motor 707 is connected to the special-shaped convex block 705.

[0026] In the embodiment of the present invention, when filtering the water flow, the water flow enters the water inlet frame 403 through the water inlet pipe 401, and then enters the annular filter screen 701 through the water inlet frame 403. At this time, the garbage stays on the annular filter screen 701 and the two corresponding filter limit plates 702. If this state is to be maintained for a long time, more and more garbage will accumulate on the annular filter screen 701, thereby blocking the mesh and affecting the drainage rate; therefore, the annular filter screen 701 needs to be rotated so that the garbage cannot be blocked on the annular filter screen 701 all the time; Therefore, it is necessary to start the motor 707 to drive the special-shaped protrusion 705 to rotate, so that the special-shaped protrusion 705 intermittently drives the rotation limit block 706 to rotate, and the rotation limit block 706 rotates around the support limit shaft 803, and at the same time drives the support circular plate 703 to rotate, thereby driving the outer ring seat 704 to rotate, and the outer ring seat 704 drives the annular filter 701 to rotate, so that the area of ​​the annular filter 701 that is in direct contact with the water flow is driven to rotate downward, so that the garbage falls to the bottom end of the filter box 402 under the action of gravity; at this time, there is no garbage in the area of ​​the top of the annular filter 701 that is in direct contact with the water flow, thereby accelerating the water inlet rate; wherein, the outer ring seat 704 is fitted and connected with the arc plate 404, so as to prevent the water flow from directly flowing out without passing through the annular filter 701, and during the rotation of the annular filter 701, the annular filter 701 will be cleaned by the inner cleaning member and the outer cleaning member, so that after one rotation, there is no garbage blocking the mesh on the annular filter 701 used for filtering.

[0027] like Figures 6 to 7 As shown, the external cleaning component includes: a placement block 409, which is arranged on the inner wall of the filter box 402; a driving spring telescopic rod 410, one end of which is on the placement block 409, and the angle of the driving spring telescopic rod 410 is directly opposite to the axis of the annular filter 701; a cleaning inclined plate 411, which is connected to the other end of the driving spring telescopic rod 410, and is cooperatively connected with the annular filter 701 and the filter limit plate 702.

[0028] In an embodiment of the present invention, during the rotation of the annular filter 701, the outer side of the annular filter 701 and the cleaning inclined plate 411 move relative to each other, so that the garbage on the annular filter 701 is preliminarily scraped off by the cleaning inclined plate 411. At the same time, when the cleaning inclined plate 411 touches the filter limit plate 702, it drives the driving spring telescopic rod 410 to contract, thereby crossing the filter limit plate 702 and scraping and cleaning the next area of ​​the annular filter 701.

[0029] like Figures 10 to 11As shown in the figure, the internal cleaning member includes: a spraying member disposed at the bottom end of the filter water bucket 801; an intermittent driving member disposed inside the filter water bucket 801 and connected to the spraying member to intermittently spray and clean the inner wall of the annular filter net 701.

[0030] As Figures 10 to 11 shown in the figure, the spraying member includes: a plurality of groups of nozzles 806 connected to the bottom end of the filter water bucket 801 and communicated with the filter water bucket 801 through a communication water valve; a sealing block 608 disposed at the bottom end inside the filter water bucket 801 to open or close the communication water valve; a sliding inclined plate 607 disposed at the bottom end inside the filter water bucket 801 and connected to the sealing block 608, and cooperatively connected with the intermittent driving member; a second support and limit block 605 disposed at the bottom end inside the filter water bucket 801; and a second spring telescopic rod 606 with one end connected to the sliding inclined plate 607 and the other end connected to the second support and limit block 605.

[0031] As shown in FIGS. 01 to Figure 11 shown in the figure, the intermittent driving member includes: a first support and limit block 602 fixedly disposed on the inner wall of the first water delivery pipe 804; a rotating fan 601 disposed on the first support and limit block 602 and rotatably connected to the first support and limit block 602; a connecting shaft 603 connected to the rotating fan 601; a plurality of groups of limit rotating rods 604 disposed at one end of the connecting shaft 603 away from the rotating fan 601, and the limit rotating rod 604 is cooperatively connected with the sliding inclined plate 607.

[0032] In an embodiment of the present invention, when the annular filter screen 701 rotates, a cleaning operation is performed from the inner end of the annular filter screen 701. After the water flow enters the filter water bucket 801, the water flow passing through the first water delivery pipe 804 drives the rotating fan 601 to rotate, thereby driving the connecting shaft 603 to rotate, and then driving the limit rotating rod 604 to rotate. The rotation of the limit rotating rod 604 pushes the sliding inclined plate 607 to slide along the bottom end of the filter water bucket 801. The sliding of the sliding inclined plate 607 drives the sealing block 608 to slide, so that the sealing block 608 is no longer directly above the water pipe, and thus the water in the filter water bucket 801 is poured into the water pipe and sprayed out from a plurality of nozzles 806, thereby spraying onto the inner end of the annular filter screen 701. The annular filter screen 701 is further cleaned by the impact of the water flow, and at the same time, small particles blocked in the mesh holes can be cleaned; while the sliding inclined plate 607 slides, the second spring telescopic rod 606 is squeezed. When the limit rotating rod 604 is not in contact with the sliding inclined plate 607, the second spring telescopic rod 606 rebounds, driving the sliding inclined plate 607 to slide in the reverse direction, thereby driving the sealing block 608 to block the water pipe, making the water flow disconnected and the nozzles 806 stop spraying, thereby realizing intermittent spraying; When the filtration is not smooth, the water flow rate will become faster, and the rotation speed of the rotating fan 601 will also become faster. As a result, the interval between the opening and closing of the sealing block 608 will become shorter, so that the spraying rate of the nozzles 806 becomes faster, thereby solving the problem of blockage of the mesh holes; when the filtration is smooth, the water flow rate will become slower, so that the spraying rate of the nozzles 806 becomes slower, to save water resources and increase the pressure in the filter water bucket 801 to ensure the water flow speed. Among them, the nozzles 806 are arranged in multiple directions to facilitate spraying and cleaning of the mesh holes.

[0033] As Figure 8 and Figure 12 As shown, the water flow detection part includes: a fixed support plate 907, arranged at one end of the first water delivery pipe 804 far from the filter water bucket 801 to seal the first water delivery pipe 804; a piston 901, sliding in the first water delivery pipe 804; a sliding rod 902, one end of which is connected to the piston 901 and the other end of which passes through the fixed support plate 907; a first spring 903, one end of which is connected to the piston 901 and the other end of which is connected to the fixed support plate 907; a support cross plate 904, arranged on the fixed support plate 907; a support vertical plate 905, connected to the support cross plate 904; a pressure sensor 906, arranged on the support vertical plate 905 and cooperatively connected to one end of the sliding rod 902.

[0034] In the embodiment of the present invention, when there is too much garbage, the filtering area of ​​the annular filter 701 is blocked in a short period of time, which will cause the water pressure to increase. As a result, when the water flows between the first water pipe 804 and the second water pipe 805, it will squeeze the piston 901, thereby driving the sliding rod 902 to slide outward. When the water pressure reaches the sliding rod 902 and contacts the pressure sensor 906, it means that there is too much garbage and the blockage is more obvious. Therefore, the rotation speed of the motor 707 is controlled to increase through an electrical signal, thereby driving the annular filter 701 to rotate faster, thereby avoiding blockage caused by too much garbage.

[0035] like Figures 6 to 7 As shown, the filter unit 4 also includes: a sewage outlet 405, which is opened on one side of the filter box 402; a limit frame 406, one end of which is connected to the filter box 402, and the other end is connected to the carriage 101; a sewage outlet 301, which is opened on one side of the carriage 101, and the sewage outlet 301 is cooperatively connected with the limit frame 406; a filter inclined plate 408, which is arranged in the filter box 402 and is at the bottom end of the annular filter screen 701 to discharge filtered impurities; a guide pipe 407, which is arranged at the bottom end of the filter box 402.

[0036] In an embodiment of the present invention, the garbage will fall downward onto the filter inclined plate 408 under the action of the annular filter mesh 701, the filter limit plate 702 and the outer ring seat 704, so that the untreated clean water flow and the water sprayed from the nozzle 806 pass through the filter inclined plate 408 and flow out from the guide pipe 407; while the garbage stays on the filter inclined plate 408, and is manually discharged from the filter inclined plate 408 through the limit frame 406 and out of the sewage trough 405.

[0037] Working principle: start the motor 707 to drive the special-shaped protrusion 705 to rotate, so that the special-shaped protrusion 705 intermittently drives the rotation limit block 706 to rotate, and the rotation limit block 706 rotates around the support limit shaft 803, and at the same time drives the support circular plate 703 to rotate, thereby driving the outer ring seat 704 to rotate, and the outer ring seat 704 drives the annular filter 701 to rotate, thereby driving the area of ​​the annular filter 701 that is in direct contact with the water flow to rotate downward, so that the garbage falls to the bottom of the filter box 402 under the action of gravity; at this time, there is no garbage in the area of ​​the top of the annular filter 701 that is in direct contact with the water flow, thereby accelerating the water inlet rate; During the rotation of the annular filter screen 701, the outer side of the annular filter screen 701 moves relative to the cleaning inclined plate 411, so that the garbage on the annular filter screen 701 is initially scraped off by the cleaning inclined plate 411. At the same time, when the cleaning inclined plate 411 touches the filter limit plate 702, it will drive the driving spring telescopic rod 410 to contract, so as to cross the filter limit plate 702 and scrape and clean the next area of the annular filter screen 701; after the water flow enters the filter water bucket 801, the water flow passing through the first water delivery pipe 804 will drive the rotating fan 601 to rotate, thus driving the connecting shaft 603 to rotate, and then driving the limit rotating rod 604 to rotate. The rotation of the limit rotating rod 604 will push the sliding inclined plate 607 to slide along the bottom end of the filter water bucket 801. The sliding of the sliding inclined plate 607 will drive the sealing block 608 to slide, so that the sealing block 608 is no longer directly above the water pipe, so that the water in the filter water bucket 801 is filled into the water pipe and sprayed out from several nozzles 806, so as to be sprayed onto the inner end of the annular filter screen 701, and the annular filter screen 701 is further cleaned by the impact of the water flow. At the same time, small particles blocked in the mesh holes can be cleaned; while the sliding inclined plate 607 slides, it squeezes the second spring telescopic rod 606. When the limit rotating rod 604 does not contact the sliding inclined plate 607, the second spring telescopic rod 606 rebounds, driving the sliding inclined plate 607 to slide in the reverse direction, thus driving the sealing block 608 to block the water pipe, making the water flow not connected and the nozzles 806 stop spraying, so as to realize intermittent spraying; the water flow enters the water pump 5 from the filter water bucket 801 through the first water delivery pipe 804 and the second water delivery pipe 805, and finally is discharged from the set drain pipe 501, thus completing the pumping and draining operations of the drainage vehicle.

[0038] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
