DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0024] For example, Figure 1 and Figure 2As shown in the figure, a water pipeline dredging device includes a fixed ring 1 and a stirring piece connected with the fixed ring 1, a plurality of sliding blocks 3 are connected with the fixed ring 1 in a radial sliding manner, one end of the sliding block 3 extends into the inside of the fixed ring 1, and the other end is provided with a scraping piece 4, the dredging device further includes a driving mechanism for driving the plurality of sliding blocks 3 to slide radially, and a transmission structure for driving the fixed ring 1 and the stirring piece to rotate synchronously.

[0025] When the pipeline is dredged, the worker first aims the dredging device at the pipeline opening and extends it into the pipeline, then drives the sliding block 3 to slide radially outward along the fixed ring 1 using the driving mechanism, and as the sliding block 3 continuously slides, the scraping piece 4 abuts against the inner wall of the pipeline, then the transmission structure is started to make the fixed ring 1 and the stirring piece rotate, and at the same time, the sliding block 3 rotates with it and the rotation of the fixed ring 1 drives the scraping piece 4 to scrape the inner wall of the pipeline, the distance of the sliding block 3 extending out of the fixed ring 1 is adjusted by the driving mechanism, so that the dredging device of the present application can dredge according to pipelines with different inner diameters, the adaptation range is large, and the operation is convenient.

[0026] As shown in Figure 3 and Figure 4 , the driving mechanism includes a connecting pipe 5 that slides in the inside of the fixed ring 1 in an axial direction, one end of the connecting pipe 5 is provided with an inclined surface 6, the sliding block 3 is provided with a guide surface 7 matched with the inclined surface 6, the inside of the fixed ring 1 is further provided with a driving structure for driving the connecting pipe 5 to slide, the driving structure includes a screw sleeve 8 screwed in the connecting pipe 5 and a limiting structure for limiting the rotation of the connecting pipe 5, and the inside of the connecting pipe 5 is provided with a threaded hole 9 screwed with the screw sleeve 8.

[0027] Among them, the outer peripheral wall of the fixed ring 1 is provided with an annular groove 10, the annular groove 10 is sleeved with an annular elastic member 11, and the plurality of sliding blocks 3 are all provided with through holes 22 for the annular elastic member 11 to pass through, in this embodiment, the annular elastic member 11 is an annular spring.

[0028] In addition, one end of the screw sleeve 8 is fixed with a rotating block 12 rotatably connected to a rotating shaft 13.

[0029] When the driving slider 3 is driven to slide along the fixed ring 1 in the radial direction, first, the worker rotates the sleeve 8 by rotating the rotating block 12. Since the connecting pipe 5 is screwed with the sleeve 8 through the threaded hole 9, and is limited by the limiting structure, the connecting pipe 5 is close to the slider 3. With the continuous movement of the connecting pipe 5, the inclined surface 6 is fitted with the guide surface 7. Under the guidance of the guide surface 7, the slider 3 can slide in the radial direction of the fixed ring 1. During the sliding process of the slider 3, when the connecting pipe 5 drives the slider 3 to slide along the fixed ring 1 in the radial direction, the annular spring expands to generate elastic force. When the sleeve 8 is rotated in the opposite direction, the connecting pipe 5 retreats and removes the force on the slider 3. The elastic member contracts to generate elastic force to reset the slider 3, so as to realize the driving effect of the driving mechanism on the slider 3. The slider 3 can slide to adapt to pipes with different inner diameters, facilitating the subsequent work to continue, and the operation is convenient.

[0030] As shown in Figure 3 , the stirring piece is a stirring blade 2 fixed to one end of the fixed ring 1. The transmission mechanism includes a rotating shaft 13 rotatably connected to the inside of the sleeve 8. One end of the rotating shaft 13 is fixed with the fixed ring 1 and the stirring blade 2. The fixed ring 1 and the stirring blade 2 are connected by a connecting block 14. The other end of the rotating shaft 13 is provided with a motor 15.

[0031] When the scraping piece 4 contacts the inner wall of the pipe, the worker starts the motor 15. The motor 15 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the fixed ring 1 and the stirring blade 2 to rotate at the same time. The rotation of the stirring blade 2 can stir the sludge block, reducing the obstruction of the sludge block to the dredging process. The rotation of the fixed ring 1 can drive the scraping piece 4 to scrape the inner wall of the pipe, so that the dredging device can more efficiently complete the dredging work in the pipe, greatly improving the dredging efficiency of the dredging device for the pipe.

[0032] As shown in Figure 1 , the end of the fixed ring 1 away from the stirring blade 2 is rotatably connected with a water storage barrel 16. The water storage barrel 16 is fixed with the motor 15 through a plurality of connecting plates 17. One end of the water storage barrel 16 is provided with a water inlet hole 18. The water inlet hole 18 is connected with an external water source, and a plurality of high-pressure pipe openings 19 communicating with the inside of the water storage barrel 16 are arranged on the outer peripheral wall of the water storage barrel 16.

[0033] During the working process of the dredging device, the setting of the water storage barrel 16 can clean the inner wall of the pipe. The external water source continuously fills water into the water storage barrel 16 through the water inlet hole 18, so that the high-pressure water flow can be sprayed out through the high-pressure pipe openings 19. In this way, the inner wall of the pipe can be flushed, and the cleaning of the pipe is more clean, which is very convenient, time-saving and labor-saving.

[0034] Among them, one end of the water storage barrel 16 is rotatably connected with the fixed ring 1, and the other end is fixed with the motor 15, so that the fixed ring 1 does not rotate when it rotates, ensuring that the dredging device can work normally.

[0035] As Figure 1 shown, the limiting structure includes limiting blocks 20 fixed on both sides of the connecting pipe 5, and limiting grooves 21 for the sliding of the limiting blocks 20 are axially arranged on both sides of the inner circumferential wall of the water storage bucket 16.

[0036] The arrangement of the limiting blocks 20 and the limiting grooves 21 makes the connecting pipe 5 only slide along the length direction of the limiting grooves 21 and cannot rotate along the circumferential direction when the sleeve 8 rotates in the connecting pipe 5.

[0037] Working principle:

[0038] When the dredging device is used to dredge the pipeline, the worker first aligns the dredging device with the pipeline opening and extends it into the pipeline, then the worker rotates the sleeve 8 by rotating the rotating block 12, since the connecting pipe 5 is threadedly connected with the sleeve 8 through the threaded hole 9 and is limited by the limiting blocks 20 and the limiting grooves 21, the connecting pipe 5 moves towards the direction of the sliding block 3, and the inclined surface 6 is in close contact with the guide surface 7, and under the guidance of the guide surface 7, the sliding block 3 can slide radially in the fixed ring 1, during the sliding process of the sliding block 3, when the connecting pipe 5 drives the sliding block 3 to slide radially outward along the fixed ring 1, the annular spring expands to generate elastic force, and when the sleeve 8 is reversely rotated to make the connecting pipe 5 retreat and remove the force on the sliding block 3, the elastic member contracts to generate elastic force to reset the sliding block 3, when the scraping sheet 4 contacts the inner wall of the pipeline, the worker starts the motor 15, the motor 15 drives the rotating shaft 13 to rotate, the rotating shaft 13 drives the fixed ring 1 and the stirring blade 2 to rotate at the same time, the rotation of the stirring blade 2 can scatter the sludge blocks to reduce the obstruction of the sludge blocks to the dredging process, and the rotation of the fixed ring 1 can drive the scraping sheet 4 to scrape the inner wall of the pipeline, so that the dredging device can more efficiently complete the dredging work in the pipeline, in addition, during the working process of the dredging device, the water storage bucket 16 can clean the inner wall of the pipeline, and the water source outside continuously fills water into the water storage bucket 16 through the water inlet hole 18, so that the high-pressure water flow can be sprayed outwards through the high-pressure pipe opening 19, that is, the inner wall of the pipeline can be flushed, so that the pipeline is more clean and convenient, time-saving and labor-saving.
