[0038] Embodiment 1

[0039] Please refer to Figures 1 to 4 as shown, this embodiment discloses a pipeline silt cleaning device, including:

[0040] A traveling mechanism 10, including a base 11 and crawler wheels 12 disposed on the left and right sides of the base 11 and with adjustable angles, and the crawler wheels 12 travel on the inner bottom of the pipeline 60;

[0041] The dredging mechanism 20 includes a mounting frame 21 detachably fixed to the base 11 and with adjustable height, a plurality of telescopic members 22 arranged at intervals in a fan shape on the mounting frame 21 and with adjustable telescopic length, and a dredging assembly 23 connected to the telescopic end of the telescopic member 22. The dredging assembly 23 is used to clean the sludge on the inner wall of the pipeline 60;

[0042] The crushing mechanism 30 includes a collecting hopper 31 detachably fixed to the base 11 and a crushing device 32 arranged in the collecting hopper 31. The collecting hopper 31 is located between the two lowermost telescopic members 22;

[0043] The flushing mechanism 40 includes a water inlet 41 and a discharge port 42. The water inlet 41 and the discharge port 42 are respectively arranged on the left and right sides of the collecting hopper 31 and communicate with the inner cavity of the collecting hopper 31.

[0044] The pipeline dredging device of this embodiment is applicable to the dredging work on the inner wall surface of the pipeline 60. By setting the traveling mechanism 10, the traveling mechanism 10 includes a base 11, crawler wheels 12 and a swinging device 13. The crawler wheels 12 of the traveling mechanism 10 can travel on the inner bottom of the pipeline 60, thereby driving the dredging mechanism 20 to travel inside the pipeline 60, realizing dredging while walking without manual operation; There are two crawler wheels 12 and the angle can be adjusted through the swinging device 13. The angle of the crawler wheels 12 can be adjusted according to the inner diameter of the pipeline 60, so as to adapt to the dredging work of pipelines 60 with different inner diameters.

[0045] It should be noted that the swinging device 13 of this embodiment can adopt a swinging structure such as in the prior art, such as the crawler chassis structure in a hanging ring type crossbeam swinging crawler chassis disclosed in Chinese Patent Publication No. CN203844863U, but is not limited to this structure.

[0046] Moreover, in this embodiment, the dredging mechanism 20 and the crushing mechanism 30 are set as detachable structures. Specifically, bolts can be used to fix the dredging mechanism 20 and the crushing mechanism 30 to the base 11, which can achieve rapid disassembly and assembly and is convenient for improving the construction efficiency.

[0047] In addition, a mounting frame 21 is arranged on the base 11, and a plurality of telescopic members 22 are arranged at intervals in a fan shape on the mounting frame 21. In practical applications, the height of the mounting frame 21 can be adjusted according to the inner diameter of the pipeline 60, so that the center of the fixed end of the telescopic member 22 is consistent with the center of the pipeline 60. Then, the telescopic length of the telescopic member 22 is adjusted, so as to adapt to the inner diameter of the pipeline 60, enabling the dredging assembly 23 to effectively dredge the inner wall surface of the pipeline 60.

[0048] This embodiment is also provided with a crushing mechanism 30 and a flushing mechanism 40. The silt generated during dredging directly falls into the aggregate hopper 31, and then is crushed by the crushing device 32 to avoid silt caking. One end of the water inlet 41 of the flushing mechanism 40 is connected to a water pipe, and high-pressure water is introduced into the inner cavity of the aggregate hopper 31 through the water pipe to disperse the silt in the inner cavity of the aggregate hopper 31, and then it is discharged into the pipeline 60 through the discharge port 42 and discharged through the normal sewage discharge of the pipeline 60, realizing automatic crushing, automatic dispersion and discharge of the silt, with a simple structure.

[0049] During the process of using the pipeline dredging device of this embodiment, it can be used in cooperation with the visual assistance mechanism 90. The visual assistance mechanism 90 includes a lidar 91 fixed on the base 11. While walking, the inside of the pipeline 60 is scanned by the lidar 91, and then an automatic model is built through a computer program, so as to initially construct a structural model of the inside of the pipeline 60 in real time. According to the automatic judgment of the computer, the silt distribution in the pipeline 60 is obtained, and then the dredging work is carried out. The walking mechanism 10 is started to make the walking mechanism 10 walk and move in the pipeline 60. When walking and moving, the silt on the inner wall surface of the pipeline 60 is removed by the dredging component 23.

[0050] In addition, the visual assistance mechanism 90 can also adopt the method of manual assistance control. Specifically, a lighting source 92 and a camera are set. The inside of the pipeline 60 is illuminated by the lighting source 92, and the image inside the pipeline 60 is taken in real time by the camera. The taken image is transmitted to the operation panel of the staff through wireless communication means, so that the staff can intuitively see the silt distribution in the pipeline 60, and then operate according to the silt distribution. For example, if there is more silt at a certain position on the inner wall of the pipeline 60, the staff controls the walking mechanism 10 to move to this position through the operation panel, and uses the dredging component 23 to repeatedly dredge this position.

[0051] Further, please refer to Figure 3 and Figure 4 , the crushing device 32 of this embodiment includes two roller shafts 321 arranged side by side in the aggregate hopper 31 and a first driving device 322 fixed to the aggregate hopper 31 and used to drive the two roller shafts 321. The first driving device 322 includes a motor fixed outside the aggregate hopper 31, a driving wheel connected to the output shaft of the motor, and a driven wheel connected to the ends of the two roller shafts 321 and meshing with the driving wheel. The two roller shafts 321 are driven to rotate by the motor at the same time, with a clever structure.

[0052] Moreover, since silt often falls at the position of the aggregate hopper 31, in order to prevent the silt from falling to the position of the first driving device 322, which may cause the driving wheel and the driven wheel to fail to rotate smoothly, in this embodiment, a protective cover (not shown) for covering the first driving device 322 is further provided outside the aggregate hopper 31. The protective cover protects the first driving device 322 to ensure that the first driving device 322 can work properly.

[0053] Generally, a lot of caked silt remains at the inner bottom of the pipeline 60. If this caked silt is not cleaned up in time, it is easy to cause pipeline blockage. Based on this, please refer to Figure 3 , the pipeline dredging device of this embodiment further includes a material shoveling mechanism 50. The material shoveling mechanism 50 includes a frame 51 fixed to the lower side of the front end of the aggregate hopper 31 and a plurality of shovel plates 52 fixed to the frame 51. The shovel plates 52 are inclined. When the traveling mechanism 10 moves forward, the shovel plates 52 can shovel up the caked silt at the inner bottom of the pipeline 60 and turn it to the rear of the traveling direction of the shovel plates 52. After the subsequent pipeline 60 is filled with water, these shoveled-up silt can be washed away to avoid accumulation.

[0054] The pipeline dredging device of this embodiment further includes a rotating mechanism 70 fixed to the mounting frame 21. The telescopic member 22 is fixed to the output end of the rotating mechanism 70. The rotation center of the rotating mechanism 70 can be adjusted to be consistent with the center of the pipeline 60. The rotating mechanism 70 can adopt a motor, and all telescopic members 22 are driven to rotate by the motor.

[0055] Moreover, the telescopic member 22 of this embodiment is a manual telescopic rod. The manual telescopic rod can adopt a rod structure that can be manually adjusted in length in the prior art, such as a manual telescopic rod disclosed in Chinese Patent Publication No. CN111248173B, a manual gear-rotating telescopic rod disclosed in Chinese Patent Publication No. CN117013433A, a new type of manual detachable telescopic rod disclosed in Chinese Patent Publication No. CN114319998A and other telescopic structures in the prior art. By adjusting the telescopic length of the manual telescopic rod, the dredging assembly 23 can contact the position of the silt on the inner wall surface of the pipeline 60, realizing effective removal of the silt on the inner wall surface of the pipeline 60.

[0056] Furthermore, the dredging assembly 23 includes a first sweeping disk 235 connected to the telescopic end of the telescopic member 22. The first sweeping disk 235 is used for dredging the inner wall surface of the pipeline 60. When the traveling mechanism 10 moves, the rotating mechanism 70 synchronously drives the first sweeping disk 235 to perform a fan-shaped reciprocating motion. The silt on the inner wall surface of the pipeline 60 is cleaned by the first sweeping disk 235, realizing effective dredging. It can adapt to the dredging work of pipelines 60 with different diameters, and compared with the dredging method of scraping by a dredging plate in the prior art, it can avoid scratching the coating on the inner wall surface of the pipeline 60.

[0057] Embodiment 2

[0058] Please refer to Figures 5 to 7 , compared with Embodiment 1, the difference in this embodiment is that: since there is a flat surface 61 at the inner bottom of part of the pipeline 60, in order to be able to clean the silt on the flat surface 61 at the inner bottom of the pipeline 60, the pipeline dredging device in this embodiment further includes a bottom surface cleaning mechanism 80. The bottom surface cleaning mechanism 80 includes an extension frame 81 fixed at one end of the walking direction of the base 11, a plurality of second sweeping disks 82 arranged at the bottom of the extension frame 81, and a second driving device for driving the second sweeping disks 82 to rotate. The second sweeping disks 82 are used to clean the flat surface 61 at the inner bottom of the pipeline 60. When the shovel plate 52 shovels up and turns over the caked silt on the flat surface 61 at the inner bottom of the pipeline 60 to the rear, these silts can be further broken up by the rotating cleaning action of the second sweeping disks 82, avoiding caking.

[0059] Embodiment 3

[0060] Please refer to Figure 8 , the dredging component 23 in this embodiment adopts a rotary scraping structure, which specifically includes a bracket 231 connected to the telescopic end of the telescopic member 22 and a scraper 232 rotatably arranged on the bracket 231. The scrapers 232 are circumferentially distributed and are used for dredging the inner wall surface of the pipeline 60. The axial section of the scraper 232 is an elliptical structure. The silt on the inner wall surface of the pipeline 60 is scraped off by the rotating scraper 232. The rolling scraping resistance is small, the dredging efficiency is high, and the dredging effect is good.

[0061] Embodiment 4

[0062] Please refer to Figure 9 and 10 , the scraper 232 in this embodiment is provided with n radial clearance grooves 233, n≥1. The clearance grooves 233 divide the scraper 232 into n + 1 sheet-shaped scraping structures 234. When the sheet-shaped scraping structures 234 scrape the silt, the silt can be scraped and fall at the position of the clearance grooves 233, and then the silt in the clearance grooves 233 is thrown off after rotation, which can realize the smooth scraping of the silt. And the sheet-shaped scraping structures 234 can be designed to be thinner, equivalent to the effect of a blade. The sharp structure is used in a rolling manner to scrape off the relatively hard silt, improving the scraping effect.

[0063] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention. These equivalent variations or substitutions are all included within the scope defined by the claims of the present invention.
