The pumping pipe 5 passes through and is fixedly connected to the top of the filter box 4, and is communicated with the water inlet end of the filter mechanism for extracting the accumulated water. One end of the water inlet pipe 10 is communicated with the water outlet end of the filter mechanism, and the other end is connected to the water inlet end of the pump body 3. The drain pipe 6 is connected to the water outlet end of the pump body 3 for discharging the filtered accumulated water to the outside.

[0022] The present invention can be used in the field of trailer-type flood control and drainage pump trucks, and can also be applied to other fields of the present invention.

[0023] Example 2 This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 8 As shown, the filtering mechanism includes a rectangular frame 8 fixedly connected to the inner wall of the top of the filter box 4, and the end of the water pumping pipe 5 located inside the filter box 4 corresponds to the inside of the rectangular frame 8, and arc plates 11 are provided on both sides of the bottom of the rectangular frame 8. The inside of the filter box 4 is provided with an outer ring seat 9 that is sealed and fitted with the bottom of the rectangular frame 8 and the two arc plates 11 for rotation. The outer wall of the outer ring seat 9 is annular and equidistantly provided with a plurality of filter slots 91 that are respectively used in conjunction with the rectangular frame 8 intermittently, and the inner wall of the plurality of filter slots 91 away from the opening is provided with a plurality of filter holes 911. The external accumulated water can be first drawn into the filter box 4 through the water pumping pipe 5, and flows downward through the inside of the rectangular frame 8, and at the same time flows into one of the corresponding filter slots 91 below. The filter slot 91 is located directly above the position of the entire outer ring seat 9, and the accumulated water flowing in is filtered through the filter holes 911 in the filter slot 91, and the accumulated water after filtering continues to flow downward, while the garbage and debris inside are temporarily stored in the filter slot 91 after filtering; as shown in FIG. Figure 3 and Figure 6 As shown, by setting two arc plates 11, the filter tank 91 located at the top can be located just below the rectangular frame 8, and the two filter tanks 91 adjacent to the top are sealed with the two arc plates 11 respectively, which can further improve the sealing performance of the top filter tank 91 for conveying accumulated water and avoid water leakage.

[0024] In one aspect of the present embodiment, the inner seal of the outer ring seat 9 is fixedly connected to the inner ring seat 12, and the outer wall of the inner ring seat 12 is annularly and equidistantly provided with a plurality of water delivery grooves 121 used in conjunction with the corresponding filter grooves 91, and the inner walls of the plurality of water delivery grooves 121 on the side away from the opening are symmetrically and fixedly connected with two water pipes 15, and the ends of the plurality of water pipes 15 away from the inner ring seat 12 are fixedly connected with the same rotating tube 13, one end of the rotating tube 13 is an open structure, and the other end is a closed structure, and the inner wall of one side of the filter box 4 is fixedly connected to a rotating motor 18, and the output shaft of the rotating motor 18 is fixedly connected to the outer wall of the closed end of the rotating tube 13; after the accumulated water enters the filter groove 91 to filter out the garbage and debris, the accumulated water passes through The filter hole 911 flows into the water delivery trough 121, and then enters the rotating tube 13 along the water guide pipe 15; when there are too many debris in the top filter trough 91, which affects the circulation of accumulated water, the rotating motor 18 can be started to drive the rotating tube 13 to rotate, and at the same time, the inner ring seat 12 is driven to rotate through the water guide pipe 15, and then the outer ring seat 9 is driven to rotate synchronously, so that the corresponding filter trough 91 and the water delivery trough 121 rotate synchronously, so that the next adjacent filter trough 91 and the water delivery trough 121 are rotated to the top, and the filter trough 91 with garbage and debris gradually rotates downward by one position, and the other filter trough 91 without garbage and debris is used to keep filtering the transported accumulated water, so as to ensure the normal transportation of the accumulated water. The outer wall of the closed end of the rotating tube 13 is fixedly connected with a sealing rotating ring 14, and the end of the sealing rotating ring 14 away from the rotating tube 13 is sealed and rotatably connected to the inner wall of one side of the filter box 4, and the rotating motor 18 is covered inside. By providing the sealing rotating ring 14, the rotating tube 13 can be rotatably connected to the inner wall of the filter box 4, thereby improving the stability of the rotation of the rotating tube 13. At the same time, the rotating motor 18 is also covered inside. The sealing rotating connection of the sealing rotating ring 14 can provide a waterproof effect for the rotating motor 18, thereby ensuring the normal use of the rotating motor 18. The bottom wall of the filter tank 91 is a raised arc surface. By providing the raised arc surface, when filtering the accumulated water, garbage and debris can be accumulated on both sides along the arc of the arc surface, thereby effectively improving the flowability of the accumulated water.

[0025] Example 3 This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 8As shown, a water pipe 16 is fixedly connected to the side of the filter box 4 away from the rotating motor 18. The end of the water pipe 16 located inside the filter box 4 is an open structure and is sealed and rotatably connected to the open end of the rotating pipe 13. The end located outside the filter box 4 is a closed structure and extends outward. The bottom side of the extension section is fixedly connected to the end of the water inlet pipe 10 away from the pump body 3. A valve body structure for water flow cutoff is provided inside the water pipe 16. The valve body structure is automatically controlled to open and close by the water delivery pressure. After the filtered accumulated water flows from the water guide pipe 15 into the rotating pipe 13, it can directly flow into the water pipe 16. The flow pressure of the accumulated water can automatically control the valve body structure to open, and then the accumulated water flows into the water inlet pipe 10 again. Finally, through the operation of the pump body 3, it is discharged from the drain pipe 6 to a designated place. Since the rotating pipe 13 and the water pipe 16 are sealed and rotatably connected, the conveyance of the accumulated water will not be affected during the process of the rotating pipe 13 rotating and adjusting the filter tank 91.

[0026] In one aspect of the present embodiment, the valve body structure includes a valve seat 19 fixedly connected to the inside of the water pipe 16, and also includes a valve stem 21 slidably connected to the closed end of the water pipe 16, the end of the valve stem 21 located inside the water pipe 16 is fixedly connected to a valve core 23 used in conjunction with the valve seat 19, and the end of the valve stem 21 located outside the water pipe 16 is fixedly connected to a connecting block 22, and a first spring 24 is fixedly connected between one side of the connecting block 22 and the outer wall of the closed end of the water pipe 16, and the first spring 24 is sleeved on the valve stem 21. When there is too little garbage and debris in the filter tank 91 and it does not affect the normal transportation of the accumulated water, the water flow is in a normal transportation state under the operation of the pump body 3, and its water pressure can put the entire valve body structure in a fully open state, that is, Figure 8 In the open state shown, the valve core 23 is away from the valve seat 19, and the valve core 23 drives the valve stem 21 to extend outward under the action of the water flow pressure, and at the same time drives the connecting block 22 to move and puts the first spring 24 in a stretched state. At this time, the accumulated water can enter the water inlet pipe 10 from the water pipe 16; when the pump body 3 stops working, the water pressure on the valve core 23 becomes smaller, and under the elastic action of the first spring 24, the valve core 23 is driven to automatically reset, and cooperates with the valve seat 19 to complete the blocking of the water pipe 16; when the accumulated water is being transported, garbage and debris in the filter tank 91 When it gradually increases, resulting in a large area of ​​clogging of the filter holes 911, the transportation of accumulated water is blocked, the water flow is reduced, and the water pressure on the valve core 23 becomes smaller. The valve core 23 will automatically reset and move under the elastic action of the first spring 24. When the rotating motor 18 is started to drive the rotating tube 13 to rotate, it will drive the outer ring seat 9 and the inner ring seat 12 to rotate, and adjust the positions of multiple filter slots 91 in sequence. At this time, the water flow is restored, and the water pressure on the valve core 23 also increases, which automatically pushes the valve core 23 to move again, and drives the valve stem 21 to extend outward, so that the accumulated water can be transported normally.

[0027] Example 4 This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 8 As shown, a cover body 20 is fixedly connected to the outer wall of the filter box 4 on one side close to the water pipe 16, and a trigger switch 32 electrically controlled and connected to the rotating motor 18 is installed on the inner wall of the cover body 20 on the side close to the filter box 4. A touch rod 25 used in conjunction with the trigger switch 32 is penetrated through the side of the cover body 20 away from the filter box 4, and one end of the touch rod 25 extends outward and is connected to one side of the connecting block 22. When the valve core 23 is subjected to water pressure and the entire valve body is in an open state, the connecting block 22 can be driven to move by the valve stem 21, and the first spring 24 can be in a stretched state. When the connecting block 22 moves, the feeler rod 25 can be driven to extend outward at the same time; when the water flow becomes smaller and the pressure on the valve core 23 is reduced, the valve core 23, the valve stem 21 and the connecting block 22 can be driven to reset and move under the elastic force of the first spring 24, and the feeler rod 25 can be driven to move and extend inward at the same time. When one end of the feeler rod 25 conflicts with the trigger switch 32, the rotating motor 18 can be automatically started once, and the rotating tube 13 can be driven to rotate a certain angle and then stop working. At this time, multiple filter tanks 91 complete a sequential movement adjustment; the water flow of the accumulated water is reduced by blocking, and the change of the water pressure on the valve core 23 can be used to make the valve core 23 drive the feeler rod 25 to move during the movement, and through the conflict with the trigger switch 32, the rotating motor 18 is controlled to start once, thereby achieving the effect of automatic blockage removal.

[0028] In one aspect of the present embodiment, a threaded section 251 is provided on one side of the feeler rod 25, and the threaded section 251 is threadedly connected to one side of the connection block 22. The distance between one end of the feeler rod 25 and the trigger switch 32 can be adjusted by rotating the feeler rod 25. On the one hand, when the valve core 23 is sealed with the valve seat 19, one end of the feeler rod 25 will not conflict with the trigger switch 32, and thus when not in use, it will not cause the start control of the rotating motor 18. Similarly, when there is not much garbage or debris, or when filtering is not required, the water flow can be reduced without driving the feeler rod 25 to conflict with the trigger switch 32, and the rotating motor 18 will not be started to drive the outer ring seat 9 to rotate; on the other hand, the distance between the feeler rod 25 and the trigger switch 32 can be adjusted to adapt to the automatic blockage removal effect under different water flows, which can be applied to the use requirements of different scenarios, thereby improving practicality.

[0029] Example 5 This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig. 9As shown, a group of plugging members for plugging the two water pipes 15 are provided in each of the multiple water delivery troughs 121. The plugging members include two plugging blocks 27 slidably connected to the inner wall of the water delivery trough 121, which are used to plug the two water pipes 15 respectively. The two plugging blocks 27 are connected by a connecting rod 28. A push rod 29 is fixedly connected to the side of one of the plugging blocks 27 away from the connecting rod 28. The other end of the push rod 29 penetrates the side of the inner ring seat 12 away from the sealing rotating ring 14 and extends outward. A fixing ring 30 is fixedly sleeved on the side of the push rod 29 located on the outside. The same second spring 31 is fixedly connected between the fixing ring 30 and the inner ring seat 12, and the second spring 31 is sleeved on the push rod 29. An arc block 17 is fixedly connected to the inner wall of the filter box body 4 away from the sealing rotating ring 14. Both sides of the arc block 17 are provided with inclined surfaces 171 used in conjunction with one end of the push rod 29. As shown Figure 6 , Fig. 9 As shown, the arc block 17 is in contact with the uppermost push rod 29, and can automatically extend and move the push rod 29 inward through the inclined surface 171 during the movement of the push rod 29, and drive the blocking block 27 to move to release the blockage of the water pipe 15. That is to say, the water pipe 15 at the top is in an open state, allowing the filtered accumulated water to flow into the rotating tube 13, while the other water pipes 15 are in a blocked state, and the accumulated water flowing into the rotating tube 13 will not flow out from the other water pipes 15, thereby ensuring the normal transportation of the accumulated water. Similarly, the second spring 31 at the top is in a compressed state after the push rod 29 moves, while the other second springs 31 are in a normal state, so that the uppermost push rod 29 can automatically reset under the elastic force of the second spring 31 after rotating and moving with the outer ring seat 9, and block the water pipe 15 again.

[0030] Example 6 This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 3As shown, a slidable garbage collection box 26 is provided inside the filter box body 4, and the garbage collection box 26 is located below the outer ring seat 9. By arranging the garbage collection box 26 below the outer ring seat 9, the filter tank 91 can rotate with the outer ring seat 9 and tilt downward, so that the garbage and impurities inside can automatically fall into the garbage collection box 26 for centralized collection, thereby achieving the effect of automatic garbage dumping; in addition, in order to facilitate the removal of the garbage collection box 26, a handle can be provided on the outer side of the garbage collection box 26; at the same time, a leaking pipe with a filter function can also be provided on the side of the garbage collection box 26 close to the handle. Since there are too many garbage and debris in the filter tank 91, the filter hole 911 is blocked, so after starting the rotating motor 18 to drive the outer ring seat 9 to rotate, the final The upper filter tank 91 rotates to the next position accordingly, but the water pipe 15 stops leaking after being blocked by the blocking block 27, and a portion of water still remains in the filter tank 91 and does not flow out completely. This portion of water will flow into the garbage collection box 26 below together with the garbage and debris during the process of dumping the garbage, and can also prevent too much garbage from adhering to the filter tank 91 and being unable to fall down by itself, so that the garbage can be discharged to a greater extent. However, this will cause too much accumulated water to remain in the garbage collection box 26. At this time, by setting a leaking pipe, the accumulated water that flows in can be discharged outward by itself, while the garbage and debris are collected in the garbage collection box 26.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the diesel engine 2, pump body 3, rotating motor 18 and trigger switch 32 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
