[0025] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 7 As shown in the figure, the pipeline dredging device provided by this utility model includes a housing 1, with cover plates 2 fixedly installed at both ends of the housing 1. Each cover plate 2 has a telescopic rod 3 fixedly installed on its exterior. Multiple telescopic rods 3 are provided. A drive assembly 4 is fixedly connected to the end of the multiple telescopic rods 3 away from the cover plate 2. Telescopic scrapers 5 are fixedly connected to the exterior of the housing 1. Multiple telescopic scrapers 5 are provided. The multiple telescopic scrapers 5 and telescopic rods 3 are arranged in a circumferential array outside the housing 1. The drive assembly 4 includes a mounting base 401, which is fixed to the end of the telescopic rod 3 away from the cover plate 2. A rotating wheel 402 is rotatably installed inside the mounting base 401. A drive motor 403 is fixedly installed on one side of the mounting base 401. The output end of the drive motor 403 passes through the mounting base 401 and is fixedly connected to the rotating wheel 402. The mounting base 401 is inclined. Multiple mounting bases 401 drive the housing 1 to move and drive the telescopic scrapers 5 to rotate around the housing 1 as an axis to perform dredging operations.

[0028] The aforementioned pipeline dredging device is powered by a drive motor 403, which drives the entire device to move along the inside of the pipeline via a rotating wheel 402. Multiple telescopic rods 3 and telescopic scrapers 5 are arranged in a circumferential array outside the casing 1 to ensure contact between the device and the inner wall of the pipeline. Once the device enters the pipeline, the telescopic rods 3 use their elastic extension and retraction to support the device's stable movement within the pipeline, while the telescopic scrapers 5 rotate around the casing 1 via the rotation of the drive assembly 4, scraping away deposits from the inner wall of the pipeline. Because the telescopic scrapers 5 are elastic, they can automatically adjust the contact pressure according to changes in the shape of the inner wall of the pipeline, effectively handling bends and complex structures within the pipeline.

[0029] The drive assembly 4 employs multiple tilted mounting bases 401. This tilted design allows the dredging device to not only move forward within the pipe but also make more flexible directional adjustments, thus accommodating bends in the pipe. As the telescopic scraper 5 rotates, it works in conjunction with the overall movement of the housing 1 to continuously scrape away debris from the inner wall of the pipe, achieving continuous and efficient dredging operations. The device, through the elastic structure design of the telescopic rods 3 and the telescopic scraper 5, can flexibly handle pipes of different diameters and bends, ensuring comprehensive coverage of the dredging operation and overcoming the problem of traditional dredging devices struggling to pass through curved pipes. Driven by the drive motor 403 and multiple telescopic rods 3 and telescopic scrapers 5 mounted outside the housing 1, the device can move autonomously inside the pipe without relying on traction ropes. Therefore, it can successfully navigate even complex and winding pipes.

[0030] In this embodiment, the telescopic scraper 5 includes a fixed plate 501 fixed outside the casing 1, and a contact plate 503 slidably installed inside the fixed plate 501 through a second spring 502. The side of the contact plate 503 away from the spring extends to the outside through the fixed plate 501, and the contact plate 503 is provided with a guide inclination angle.

[0031] In the working process, the contact plate 503 is elastically telescoped by the second spring 502 under the pressure of the inner wall of the pipeline. When the device encounters a pipeline with different diameters or bends, the contact plate 503 will automatically adjust elastically according to the shape of the inner wall of the pipeline to ensure that it always maintains close contact with the inner wall of the pipeline. This can effectively prevent the scraper from not being able to adhere to the pipe wall due to changes in the shape of the pipeline, ensuring the efficiency of dredging. The outer end of the contact plate 503 is provided with a guide inclination angle, which is designed to guide the device to move smoothly in the pipeline, so that the contact plate 503 can smoothly enter the optimal position of contact with the pipe wall. The guide inclination angle helps to reduce the jamming phenomenon of the device when encountering a curved or narrow area of the pipeline, ensuring the smooth progress of the dredging device, while effectively removing the deposits on the inner wall of the pipeline.

[0032] In this embodiment, the telescopic rod 3 includes a fixed tube 301 fixed outside the cover plate 2, and a movable rod 302 slidably installed inside the side of the fixed tube 301 away from the cover plate 2. A first spring 303 is arranged between the movable rod 302 and the fixed tube 301, and the first spring 303 is located in the inner cavity of the fixed tube 301 on the side close to the cover plate 2. The movable rod 302 is rotatably arranged.

[0033] The fixed tube 301 is fixed outside the cover plate 2 and internally installed with the slidable movable rod 302. The first spring 303 is arranged between the movable rod 302 and the fixed tube 301, and the first spring 303 is located in the inner cavity of the fixed tube 301 on the side close to the cover plate 2, which plays a role of elastic support. This structure enables the movable rod 302 to slide and rotate within a certain range in the fixed tube 301, adapting to the bending and variable diameter of the pipeline.

[0034] When the device travels in the pipeline, the first spring 303 provides elastic support according to the change of the inner diameter of the pipeline, and the movable rod 302 can slide forward and backward in the fixed tube 301, maintaining the supporting force between the telescopic rod 3 and the inner wall of the pipeline. This can ensure that the dredging device is always in a stable state, avoiding excessive or loose contact, which helps the continuity and stability of dredging.

[0035] The rotatable design of the movable rod 302 allows the telescopic rod 3 to rotate freely in the fixed tube 301 and change direction by driving the rotating wheel 402. When the angle of the rotating wheel 402 gradually deviates from the position consistent with the direction of the pipeline, the overall forward speed of the device will decrease accordingly. The purpose of this design is to slow down the forward speed when the device needs to perform more delicate dredging operations, so that the telescopic scraper 5 can more finely scrape the deposits on the inner wall of the pipeline. By slowing down, the device can more thoroughly clean complex or heavily deposited areas.

[0036] In this embodiment, the inside of the casing 1 is fixedly installed with a steering motor 8, and the output ends of the steering motor 8 on both sides are fixedly connected with large helical gears 6. The end of the fixed tube 301 away from the driving assembly 4 is rotatably installed with a small helical gear 7, which is meshingly connected with the large helical gears 6. The side of the small helical gear 7 away from the large helical gear 6 is fixedly connected with a fixed rod 304, and the inside of the side of the fixed rod 304 away from the small helical gear 7 is slidably installed with a sliding rod 305, and the end of the sliding rod 305 away from the small helical gear 7 is fixedly connected with a mounting seat 401.

[0037] When the motor is working, the small helical gear 7 is driven to rotate by the large helical gear 6, thereby realizing the power output of the transmission system. This design of helical gears provides smooth and precise transmission, ensuring the flexibility and stability of the dredging device when turning in the pipeline. The small helical gear 7 is connected with the fixed rod 304, and when the small helical gear 7 rotates, it drives the fixed rod 304 to move correspondingly through the meshing action of the gears. The fixed rod 304 and the sliding rod 305 are in sliding connection, and the other end of the sliding rod 305 is fixedly connected with the mounting seat 401, so that the transmission system of the whole device can flexibly adjust the direction. This design makes the dredging device move and turn in different directions in the pipeline, especially in complex curved pipelines.

[0038] The steering motor 8 not only serves as a driving force for steering, but also as a core part of the energy integration system. Through two power supply modes, it meets the dredging needs in different scenarios:

[0039] The dredging device can be equipped with a built-in battery, which is directly connected with the steering motor 8 to provide the power required by the whole device. This power supply mode is suitable for situations where it is difficult to arrange wires inside the pipeline and the device needs to operate autonomously. The built-in battery drives the steering motor 8 and other dredging components to realize autonomous dredging operation of the whole device.

[0040] If the device needs to run for a long time or the built-in battery cannot meet the long-time working requirement, the whole device can also be powered by an external power line. The external power line is connected to the steering motor 8 to provide stable power supply for it, ensuring the long-time and efficient operation of the device. This design is especially suitable for larger pipelines or complex dredging tasks, and the external power supply can provide continuous power support

[0041] The working principle of the utility model:

[0042] In use, the driving assembly 4 adopts a plurality of installation seats 401 installed obliquely, through the oblique design of the installation seat 401, the dredging device can not only advance in the pipeline, but also can be more flexible in direction adjustment, so as to cope with the curved part in the pipeline. When the telescopic scraper 5 rotates, cooperate with the movement of the whole machine shell 1, continuously scrape off the dirt on the inner wall of the pipeline, realize continuous and efficient dredging operation. The device can flexibly cope with different diameter and curved pipeline through the elastic structure design of the telescopic rod 3 and the telescopic scraper 5, ensure the comprehensive coverage of the dredging operation, overcome the problem that the traditional dredging device is difficult to pass through the curved pipeline. Through the driving motor 403 and the plurality of telescopic rods 3 and telescopic scrapers 5 installed outside the machine shell 1, the device can move in the pipeline by itself, without relying on the traction rope. Therefore, even in the case of complex pipeline bending, it can also pass smoothly.
