Description

Technical Field

[0001] The utility model relates to the technical field of pipeline desilting, in particular to a sweeping disc type pipeline desilting device. Background Art

[0002] Pipeline desilting is to dredge the pipeline, clean the silt inside the pipeline, and keep it unobstructed for a long time to prevent urban waterlogging. Pipeline desilting has become an important task that cannot be ignored by the drainage department. If a large amount of debris and cement sand from infrastructure construction sites are discharged into the drainage pipe, sedimentation and accumulation will cause the pipeline to be blocked. Failure to desilt and dredge the pipeline will cause sewage overflow, pollute the environment, and bring trouble to people's lives.

[0003] A pipeline dredging device is usually used to clean the pipeline. This type of device can refer to a pipeline dredging robot disclosed in Chinese patent application No. 202311649443.9, which includes a walking body and a dredging device arranged at the front end of the walking body. The dredging device includes a connecting shaft and a plurality of dredging plates. The plurality of dredging plates are distributed circumferentially on the connecting shaft with the axis of the connecting shaft as the center of the circle to form a dredging disc. The dredging plates and the connecting shaft can be slidably connected, and the connecting shaft is installed at the front end of the walking body. A dredging knife is fixedly installed on the plate surface of the plurality of dredging plates facing away from the walking body.

[0004] The existing pipeline dredging robots generally have the following problems: 1. They adopt a single-track walking structure, and the angle of the track cannot be adjusted, making it difficult to adapt to the dredging of pipelines with different inner diameters; 2. In order to improve the waterproof and anti-corrosion properties of the inner wall of the pipeline, a layer of waterproof and anti-corrosion coating is usually sprayed inside the pipe wall. However, the existing pipeline dredging robots mostly use dredging plates to scrape away silt. The dredging plates can easily scratch the coating on the inner wall of the pipeline, affecting the waterproof and anti-corrosion properties of the pipeline.

[0005] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0006] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a sweeping disc type pipeline dredging device to solve the problems that the pipeline dredging robot in the prior art cannot adapt to the movement of pipelines of different diameters and the dredging plate easily scratches the coating on the inner wall of the pipeline.

[0007] A sweeping disc type pipeline desilting device, comprising:

[0008] The walking mechanism includes a base and angle-adjustable track wheels provided on both sides of the base, wherein the track wheels run on the inner bottom of the pipe;

[0009] A mounting frame fixed to the base and adjustable in height;

[0010] A rotating mechanism is fixed to the mounting frame, wherein the center of rotation of the rotating mechanism can be adjusted to coincide with the center of the pipeline;

[0011] The first dredging mechanism includes a plurality of telescopic parts fixed to the output end of the rotating mechanism and distributed in a fan-shaped manner, and a first sweeping disc connected to the end of the telescopic part away from the rotating mechanism. The first sweeping disc is distributed in a circle and is used to dredge the inner wall of the pipeline.

[0012] Specifically, the walking mechanism further includes swing devices provided on both sides of the base, and the two swing devices respectively drive the two track wheels to swing.

[0013] Specifically, the mounting bracket is provided with a height adjustment device, and the height adjustment device is a manual lifting device, a pneumatic lifting device, a hydraulic lifting device or an electric lifting device.

[0014] Specifically, the telescopic member is a manual telescopic rod, a pneumatic telescopic rod, a hydraulic telescopic rod or an electric telescopic rod.

[0015] Specifically, the rotating mechanism is a motor.

[0016] Specifically, the first sweeping disc includes a first circular disc detachably fixed to the telescopic member and a first cleaning belt annularly arranged on the first circular disc.

[0017] Specifically, the pipeline dredging device also includes a second dredging mechanism, which includes an extension frame fixed to one end of the base in the walking direction, a plurality of second sweeping discs arranged at the bottom of the extension frame, and a driving device for driving the second sweeping discs to rotate, and the second sweeping discs are used to clean the plane of the bottom inner side of the pipeline.

[0018] Specifically, the second sweeping disc includes a second disc detachably connected to the output end of the driving device and a second cleaning belt annularly arranged on the second disc.

[0019] Beneficial effects of the utility model:

[0020] 1. The sweeping disc type pipeline desilting device of the utility model is suitable for desilting the inner wall of the pipeline. By setting a walking mechanism, it can realize desilting while walking, without manual operation. The crawler wheel has two adjustable angles. The angle of the crawler wheel can be adjusted according to the inner diameter of the pipeline, thus adapting to the desilting work of pipelines with different inner diameters.

[0021] 2. The height of the mounting bracket can be adjusted according to the inner diameter of the pipeline so that the rotation center of the rotating mechanism is consistent with the center of the pipeline.

[0022] 3. It can be used in conjunction with a visual control device to communicate with the sweeping disc type pipeline dredging device. First, adjust the height through the mounting bracket so that the rotation center of the rotating mechanism is consistent with the center of the pipeline. Then adjust the telescopic length through the telescopic part, start the walking mechanism, and make the walking mechanism move in the pipeline. At the same time, the rotating mechanism synchronously drives the first sweeping disc to perform circular motion. The silt on the inner wall of the pipeline is cleaned by the first sweeping disc to achieve effective dredging. It can adapt to the dredging work of pipelines with different diameters, and compared with the scraping dredging method of the dredging plate in the existing technology, it can avoid scratching the coating on the inner wall of the pipeline.

[0034] Example 1

[0035] Please refer to Figures 1 to 4 As shown, this embodiment discloses a sweeping disc type pipeline desilting device, comprising:

[0036] The walking mechanism 10 includes a base 11 and track wheels 12 provided on both sides of the base 11 and having adjustable angles. The track wheels 12 run on the inner bottom of the pipe 60.

[0037] A mounting frame 20, fixed to the base 11 and having adjustable height;

[0038] The rotating mechanism 30 is fixed to the mounting frame 20 , and the rotation center of the rotating mechanism 30 can be adjusted to coincide with the center of the pipe 60 ;

[0039] The first dredging mechanism 40 includes a plurality of telescopic members 41 fixed to the output end of the rotating mechanism 30 and distributed in a fan-shaped manner, and a first sweeping disc 42 connected to the end of the telescopic member 41 away from the rotating mechanism 30. The first sweeping disc 42 is distributed in a circle and is used to dredge the inner wall of the pipe 60.

[0040] The sweeping disc type pipeline dredging device of this embodiment is suitable for dredging the inner wall surface of the pipeline 60. By providing a walking mechanism 10, the track wheels 12 of the walking mechanism 10 can travel on the inner bottom of the pipeline 60, thereby driving the first dredging mechanism 40 to move inside the pipeline 60, realizing dredging while walking without manual operation; the track wheels 12 have two adjustable angles, and the angle of the track wheels 12 can be adjusted according to the inner diameter of the pipeline 60, thereby adapting to the dredging work of pipelines 60 with different inner diameters.

[0041] In addition, a mounting frame 20 is provided on the base 11, and a rotating mechanism 30 is provided on the mounting frame 20. The telescopic member 41 of the first dredging mechanism 40 is fixed to the output end of the rotating mechanism 30. In actual application, the height of the mounting frame 20 can be adjusted according to the inner diameter of the pipe 60, so that the rotation center of the rotating mechanism 30 is consistent with the center of the pipe 60, and then the telescopic length of the telescopic member 41 is adjusted to adapt to the inner diameter of the pipe 60, so that the first sweeping disc 42 can effectively dredge the inner wall surface of the pipe 60.

[0042] When using the sweeping disc type pipeline dredging device of this embodiment, it can be used in conjunction with a visual control device to communicate with the sweeping disc type pipeline dredging device of this embodiment, and then the sweeping disc type pipeline dredging device of this embodiment is placed in the pipeline 60 to be dredged. Before dredging, the height is first adjusted by the mounting frame 20 so that the rotation center of the rotating mechanism 30 is consistent with the center of the pipeline 60, and then the telescopic length is adjusted by the telescopic member 41 so that the first sweeping disc 42 can be against the inner wall surface of the pipeline 60, and then the dredging work is carried out, and the walking mechanism 10 is started to make the walking mechanism 10 move in the pipeline 60. During the walking and moving, the rotating mechanism 30 synchronously drives the first sweeping disc 42 to perform a circular motion, and the silt on the inner wall surface of the pipeline 60 is swept by the first sweeping disc 42, thereby achieving effective dredging, and being able to adapt to the dredging work of pipelines 60 with different diameters. Compared with the dredging plate scraping dredging method in the prior art, it can avoid scratching the coating on the inner wall surface of the pipeline 60.

[0043] Furthermore, the walking mechanism 10 of this embodiment further includes swing devices 13 disposed on both sides of the base 11. The two swing devices 13 respectively drive the two track wheels 12 to swing, thereby adjusting the angles of the two track wheels 12, improving the grip of the two track wheels 12 on the inner wall of the pipe 60, and preventing slipping. It should be noted that the swing device 13 of this embodiment can adopt a swing structure as in the prior art, such as the track chassis structure of a ring-type crossbeam swinging track chassis disclosed in Chinese Patent Publication No. CN203844863U, but is not limited to this structure.

[0044] The mounting frame 20 of this embodiment is provided with a height adjustment device 21. The height of the mounting frame 20 is adjusted by the height adjustment device 21 so that the rotation center of the rotating mechanism 30 is consistent with the center of the pipe 60. Then, the telescopic length thereof is adjusted by the telescopic member 41 to adapt to the inner diameter of the pipe 60, so that the first sweeping disc 42 can effectively desilt the inner wall surface of the pipe 60.

[0045] Please refer to Figure 4The mounting frame 20 of this embodiment includes an upper frame body and a lower frame body, and a height adjustment device 21 is arranged between the upper frame body and the lower frame body. As a preferred embodiment, the height adjustment device 21 of this embodiment is a manual lifting device, which includes a movable shaft 211 and a threaded locking member 212. The movable shaft 211 is connected to the lower end of the upper frame body of the mounting frame 20, and a movable hole is provided at the upper end of the lower frame body of the mounting frame 20. The movable shaft 211 can be inserted into the movable hole along the axial direction, and a radial screw hole is provided on the lower frame body of the mounting frame 20. The threaded locking member 212 is threadedly matched with the screw hole. The threaded locking member 212 is loosened or locked by loosening or tightening the threaded locking member 212. Using the manual lifting device to adjust the height of the mounting frame 20 can simplify the structure and reduce equipment costs.

[0046] Of course, the height adjustment device 21 adopts a manual lifting device, which is only one of the better implementation methods. In other embodiments, the height adjustment device 21 can also adopt a pneumatic lifting device, a hydraulic lifting device or an electric lifting device, and is not limited to the manual lifting device of this embodiment.

[0047] Furthermore, the telescopic member 41 of this embodiment is a manually adjustable telescopic rod. The manually adjustable telescopic rod may employ a conventional manually adjustable rod structure, such as the manual telescopic rod disclosed in Chinese Patent Publication No. CN111248173B, the manual gear-crank telescopic rod disclosed in Chinese Patent Publication No. CN117013433A, or the novel manually detachable telescopic rod disclosed in Chinese Patent Publication No. CN114319998A. By adjusting the length of the manually adjustable telescopic rod, the first sweeping disc 42 can be brought into contact with the inner wall of the pipe 60, thereby effectively cleaning the sludge on the inner wall of the pipe 60.

[0048] Of course, the telescopic member 41 adopts a manual telescopic rod, which is only one of the preferred implementations. In other embodiments, the telescopic member 41 can also adopt a pneumatic telescopic rod, a hydraulic telescopic rod or an electric telescopic rod, and is not limited to the manual telescopic rod of this embodiment.

[0049] In addition, the rotating mechanism 30 of this embodiment is a motor, which can be a high-torque motor such as a DC motor, an asynchronous motor, a synchronous motor or a stepping motor, which can provide a large torque output, thereby providing a strong cleaning effect to the first sweeping disc 42.

[0050] For further information, please refer to Figure 1 and Figure 2 The first sweeping disc 42 includes a first disc 421 that is detachably fixed to the telescopic member 41 and a first cleaning belt 422 that is annularly arranged on the first disc 421. The first cleaning belt 422 can be made of a deformable strip of plastic material. The cleaning process does not damage the inner wall of the pipe 60 and can effectively avoid scratching the coating on the inner wall of the pipe 60.

[0051] Example 2

[0052] Please refer to Figures 5 to 8 Since the inner bottom of part of the pipe 60 has a flat surface 61, in order to clean the silt on the flat surface 61 of the inner bottom of the pipe 60, the pipe dredging device of this embodiment also includes a second dredging mechanism 50. The second dredging mechanism 50 includes an extension frame 51 fixed to one end of the base 11 in the moving direction, a plurality of second sweeping discs 52 provided at the bottom of the extension frame 51, and a driving device for driving the second sweeping discs 52 to rotate. The second sweeping discs 52 are used to clean the flat surface 61 of the inner bottom of the pipe 60.

[0053] The sweeping disc type pipeline desilting device of this embodiment is placed in the pipeline 60 to be desilted. Before desilting, the height is first adjusted by the mounting frame 20 so that the rotation center of the rotating mechanism 30 is consistent with the center of the pipeline 60. Then, the telescopic length of the telescopic member 41 is adjusted so that the first sweeping disc 42 can abut against the inner wall of the pipeline 60. Then, the height of the extension frame 51 is adjusted so that the second sweeping disc 52 can abut against the plane 61 at the bottom inside the pipeline 60. Then, desilting is carried out. The walking mechanism 10 is started to move in the pipeline 60. When moving, the rotating mechanism 30 synchronously drives the first sweeping disc 42 to perform fan-shaped reciprocating motion, and the silt on the inner wall of the pipe 60 is cleaned by the first sweeping disc 42. At the same time, the driving device drives the second sweeping disc 52 to rotate, and the second sweeping disc 52 is used to clean the silt on the bottom plane 61 inside the pipe 60, thereby achieving effective dredging. It can adapt to the dredging work of the pipe 60 with a bottom plane 61. Moreover, the use of the first sweeping disc 42 and the second sweeping disc 52 can avoid scratching the coating on the inner wall of the pipe 60 compared to the scraping dredging method of the dredging plate in the prior art.

[0054] Furthermore, the second sweeping disc 52 includes a second disc 521 detachably connected to the output end of the driving device and a second cleaning belt 522 arranged in a ring shape on the second disc 521. The second cleaning belt 522 can be made of a deformable strip of plastic material. The cleaning process does not damage the inner wall surface of the pipe 60 and can effectively avoid scratching the plane 61 at the bottom inner side of the pipe 60.

[0055] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
