Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline maintenance technology, specifically to an automatic mobile rapid dredging device for pipelines. Background Technology
[0002] Pipeline systems play a vital role in modern industry, urban infrastructure, oil and gas transportation, and wastewater treatment. Over time, impurities such as silt, dirt, grease, and sediment often accumulate inside pipelines. Regular dredging and maintenance are essential measures to ensure their normal operation and extend their service life.
[0003] For example, Chinese patent CN202022696874.9 discloses a pipeline dredging device. The first drive component drives multiple hook plates to rotate and retract toward the axis of the dredging shaft. Then, the dredging shaft is inserted into the pipeline from the end near the first dredging mechanism and pushed into a suitable position in the pipeline. The first drive component then drives the hook plates to rotate toward the axis away from the dredging shaft, thereby opening them into an umbrella shape. Then, the dredging shaft is pulled out of the pipeline, so that the hook plates carry out silt, plastic film and other airtight debris or long strips of debris such as tree branches from the pipeline.
[0004] However, the dredging device requires manual operation and the equipment configuration needs to be adjusted according to the specific conditions of the pipeline. Many pipelines have uneven diameters, many bends, or contain pipe sections of different materials, making it difficult for these devices to adapt to different pipeline environments and move smoothly within them to complete the cleaning work.
[0005] Based on this, the present invention designs an automatic moving and rapid dredging device for pipelines to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide an automatic moving and rapid dredging device for pipelines to solve the problems mentioned in the background art.

[0008] Preferably, the auxiliary support assembly includes a support curved plate and a spring, the left end of the support curved plate is hinged to the mounting groove, and the spring is provided on the side of the support curved plate near the dredging body.
[0009] Preferably, one end of the spring is fixedly connected to the corresponding mounting groove, and the other end of the spring is fixedly connected to the support plate.

[0012] Preferably, a torsion spring is fitted into the slot, and the two ends of the torsion spring are respectively connected to the slot and the support leg.
[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0014] I. This utility model, by setting up a drill bit, brush plate, auxiliary support components, support legs, and traveling wheels, utilizes the drill bit and brush plate on the dredging body to break up and clean the silt inside the pipe. At the same time, the auxiliary support components and traveling wheels ensure the stable movement of the device inside the pipe. Through the cooperation of the locking groove and support legs, the device can adapt to pipes of different angles, ensuring the continuity and integrity of the dredging process. It can automatically adapt to pipes of different diameters and curvatures, complete the dredging work without manual operation, and can move automatically inside the pipe, improving dredging efficiency and reducing damage to the pipe.
[0015] II. The support plate in this utility model is adjusted by a spring, which can automatically adjust the support force according to the degree of curvature of the pipe, ensuring that the device can maintain good contact and support in pipes of different diameters and curvatures. Using a drill bit and a brush plate, it can effectively break up and clean up the silt in the pipe. The "conical" structure of the drill bit allows it to apply concentrated force to the silt during rotation, thereby improving the breaking efficiency. After the drill bit breaks up the silt, the brush plate cleans up the residue after breaking it up by rotating, ensuring the cleanliness of the inside of the pipe. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] Please see Figure 1 - Figure 5 Example 1 illustrates an automatic moving rapid dredging device for pipelines, comprising a dredging body 1, a connecting sleeve 2 fixedly connected to the left side of the dredging body 1, a drill bit 3 rotatably connected to the left end of the connecting sleeve 2, several sets of brush plates 4 rotatably connected between the connecting sleeve 2 and the dredging body 1, several mounting grooves 5 evenly spaced on the outer wall of the dredging body 1, auxiliary support components 6 matched and connected in each of the mounting grooves 5, a brush ring 7 rotatably connected to the outer wall of the right end of the dredging body 1, a fixing block 8 fixedly connected to the right end of the dredging body 1, a locking groove 9 evenly spaced on the right edge of the fixing block 8, a support leg 10 hinged in the locking groove 9, and a traveling wheel 11 rotatably connected to the right end of the support leg 10;
[0026] Please see Figure 2 and Figure 5 The auxiliary support component 6 shown in the figure includes a support curved plate 601 and a spring 602. The left end of the support curved plate 601 is hinged to the mounting groove 5, and the spring 602 is provided on the side of the support curved plate 601 near the dredging body 1.
[0027] In this embodiment, the dredging device is first placed inside the pipe to be cleaned. After the device is started, the drill bit 3 begins to rotate. Utilizing its conical structure, it can effectively break up the sediment inside the pipe. As the drill bit penetrates deeper, the dredging body 1 drives the brush plate 4 and auxiliary support assembly 6 to move along the pipe. The brush plate 4 cleans the inner wall of the pipe during rotation, while the auxiliary support assembly 6 provides the necessary support force to ensure the stable movement of the dredging body 1 inside the pipe. After the dredging operation is completed, the traveling wheels 11 drive the device out of the pipe, completing one dredging process. This efficiently and automatically completes the pipe dredging work, greatly improving work efficiency and reducing the complexity and labor intensity of manual operation.
[0028] It should be noted that the brush plate 4 is made of wear-resistant material and has dense bristles on its surface, which can scrub the inner wall of the pipe when the sludge removal body 1 rotates to remove residual sludge. The auxiliary support component 6 provides stable support when the sludge removal body 1 rotates to prevent the device from shifting or shaking in the pipe. The brush ring 7 can rotate flexibly to adapt to the sludge removal needs at different angles.
[0029] Example 2
[0030] Please see Figure 3 and Figure 5 Example 2 is described below. This embodiment further illustrates Example 1. In the figure, one end of the spring 602 is fixedly connected to the corresponding mounting groove 5, and the other end of the spring 602 is fixedly connected to the support curved plate 601.
[0031] Furthermore, several mounting slots 5 are divided into two groups, and the two groups of mounting slots 5 are staggered.
[0032] In this embodiment, the spring 602 in the auxiliary support assembly 6 applies pressure to the support curved plate 601, so that the support curved plate 601 can automatically adjust its angle according to the degree of pipe curvature, thereby providing a more stable and uniform support force, thus adapting to different pipes and ensuring the smooth progress of the dredging process. In addition, the elastic characteristics of the spring 602 can also absorb part of the impact force caused by pipe curvature or irregular shape, further protecting the device from damage.
[0033] Example 3
[0034] Please see Figure 3 and Figure 6 Example 3 is described below. This embodiment further illustrates Example 2. In the figure, the drill bit 3 has a cone-shaped structure that is smaller on the left and larger on the right. The drill bit 3 is made of high-strength alloy material.
[0035] Furthermore, a torsion spring 12 is fitted into the slot 9, with both ends of the torsion spring 12 connected to the slot 9 and the support leg 10, respectively.
[0036] In this embodiment, the drill bit 3 made of high-strength alloy material is used to ensure that it can withstand greater pressure and wear during the dredging process. The tip of the drill bit 3 can also be equipped with multiple cutting edges, which can effectively cut and break up the silt in the pipe. The fixing block 8 is used to fix the support leg 10 to ensure that the support leg 10 remains stable during the dredging process. The traveling wheel 11 is made of wear-resistant material and can move smoothly in the pipe, reducing damage to the inner wall of the pipe.
[0037] Specifically, when the dredging body 1 reaches the predetermined position, the support leg 10 unfolds under the action of the torsion spring 12 and supports itself on the inner wall of the pipe to maintain the stability of the device. At this time, the traveling wheel 11 can drive the device to move inside the pipe to carry out continuous dredging operations. During the dredging process, the combined use of the brush ring 7 and the brush plate 4 can more thoroughly remove impurities from the pipe. When the support leg 10 moves under the drive of the traveling wheel 11, the torsion spring 12 can provide a certain rebound force to ensure that the support leg 10 maintains appropriate contact pressure on the inner wall of the pipe and prevent the device from slipping or becoming unstable during movement.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
