Description

Technical Field

[0001] This utility model relates to a rainwater and sewage pipe damage detection device, belonging to the field of sewage pipe detection technology. Background Technology

[0002] Sewage pipes are responsible for collecting and transporting sewage and rainwater within a city, and are an important part of urban infrastructure. They are made of various materials, including concrete pipes and ductile iron pipes. Large drainage pipes laid under city streets transport sewage from the entire area to sewage treatment plants. Over time, these pipes can become damaged, requiring the use of inspection devices for regular maintenance.

[0003] Patent CN221855763 discloses a rainwater and sewage pipe damage detection device, including a sewage pipe with a fixed shell inside. A cleaning component is installed on the inner wall of the sewage pipe, and a vehicle body is located on the left side of the fixed shell. The cleaning component includes a scraper, a rotating ring rotatably connected to the outer surface of the fixed shell, and a fixed seat fixedly connected to the outer surface of the rotating ring. A hydraulic cylinder is fixedly connected to the inner wall of the fixed seat. This invention, through the cleaning component, specifically by activating the hydraulic cylinder to adjust the scraper's lifting distance, allows the scraper to contact the inner wall of the sewage pipe, enabling its use in sewage pipes of different sizes. After adjustment, a motor drives a gear to rotate, which in turn drives the fixed seat to rotate via the rotating ring, causing the scraper to rotate accordingly. This effectively cleans the inner wall of the sewage pipe, facilitating the device's movement within the pipe and preventing jamming.

[0027] like Figures 1-5 As shown, a rainwater and sewage pipe damage detection device includes a fixed shell 3 composed of a first shell 1 and a second shell 2. The first shell 1 and the second shell 2 are detachably fixedly connected by a fixing component. A sealing component is provided at the connection between the first shell 1 and the second shell 2. A cleaning component is provided on the left side of the fixed shell 3. A set of arc-shaped clamping plates 4 are provided on the inner walls of both the first shell 1 and the second shell 2. The two sets of arc-shaped clamping plates 4 are symmetrically arranged. An installation plate 5 is clamped between the arc-shaped clamping plates 4. A dual-axis motor 6 is provided on the right end face of the installation plate 5. A threaded rod 7 is connected to the output shaft of the dual-axis motor 6. A telescopic square column 8 is threadedly connected to the threaded rod 7. The telescopic square column 8 is telescopically engaged with the fixed shell 3. A drive component is provided at the end of the telescopic square column 8 away from the dual-axis motor 6.

[0028] In the above technical solution, by setting the fixed shell 3 to be detachably and fixedly connected by the first shell 1 and the second shell 2 through the fixing component, the position adjustment of the drive seat 27 can be achieved by the rotation of the dual-axis motor 6 driving the threaded rod 7 to rotate, thereby driving the telescopic square column 8 to extend and retract directly, which makes the structure simple and easy to maintain.

[0029] In this invention, a set of fixing components is provided, and the fixing components are symmetrically arranged at the top and bottom of the outer cylindrical surface of the fixing shell 3. The fixing components include a first connecting plate 9 and a second connecting plate 10. The first connecting plate 9 is fixedly connected to the outer cylindrical surface of the first shell 1 near the second shell 2, and the second connecting plate 10 is fixedly connected to the outer cylindrical surface of the second shell 2 near the first shell 1. The first connecting plate 9 and the second connecting plate 10 are detachably fixedly connected by bolts 11 and nuts 12.

[0030] In the above technical solution, by setting a fixing component, the bolts 11 and nuts 12 can be easily removed with a wrench to contact the fixed state between the first connecting plate 9 and the second connecting plate 10, which makes it easy to disassemble the fixing shell 3 and maintain its internal components.

[0031] In this invention, the sealing assembly includes a sealing groove 13, which is formed on the end face of the first housing 1 near the second housing 2. A sealing gasket 14 is provided inside the sealing groove 13, and a sealing protrusion 15 is provided on the end face of the second housing 2 near the first housing 1. The sealing protrusion 15 is engaged within the sealing groove 13 when the fixing housing 3 is fixed.

[0032] In the above technical solution, by setting a sealing component and utilizing the plasticity of the sealing gasket 14, the gap between the sealing protrusion 15 and the sealing groove 13 can be sealed when the fixed shell 3 is fixed, thus preventing water from entering.

[0033] In this utility model, the cleaning component includes a drive motor 16, which is fixedly connected to a vertical plate 17. The vertical plate 17 is fixedly connected to the inner left wall of the first housing 1. The output shaft of the drive motor 16 extends through the fixed housing 3. A rotating plate 18 is installed on the part of the drive motor 16 that extends through the fixed housing 3. Several telescopic structures are installed in a circular shape on the end face of the rotating plate 18 away from the fixed housing 3. Each telescopic structure has a cleaning scraper 19 at one end of its circumferential circle. An inclined pressure plate 20 is provided at the end of the cleaning scraper 19 away from the fixed housing 3.

[0034] In the above technical solution, by setting up a cleaning component, the drive motor 16 can drive the rotating plate 18 to rotate, thereby driving the cleaning scraper 19 to rotate and scrape away the stains on the inner wall of the pipe, facilitating the inspection of the inner wall of the pipe. By setting up an inclined pressure plate 20, when the device enters the inner wall of the pipe, one end of the inclined pressure plate 20 first extends into the pipe, and the inner wall of the pipe exerts a squeezing force on the inclined pressure plate 20. The telescopic structure compresses the pressure plate, making the cleaning scraper 19 suitable for cleaning the inner walls of pipes of different specifications. At the same time, the position adjustment of the cleaning scraper 19 is more convenient and direct.

[0035] In this utility model, the telescopic structure includes a fixed block 21, and a telescopic square cavity 22 is provided inside the fixed block 21. A square piston plate 23 is movably disposed inside the telescopic square cavity 22. A spring 24 is provided between the square piston plate 23 and the side wall of the telescopic square cavity 22. A connecting rod 25 is provided at the end of the square piston plate 23 away from the spring 24. The end of the connecting rod 25 away from the square piston plate 23 is fixedly connected to the cleaning scraper 19.

[0036] In the above technical solution, by setting up a telescopic structure and utilizing the elastic force of the spring 24, when the device enters the pipe, the inclined pressure plate 20 is subjected to force, squeezing the connecting rod 25, which in turn drives the square piston plate 23 to move towards one end of the spring 24. The spring 24 is compressed and subjected to force, which makes it easy for the cleaning scraper 19 to adapt to pipes of different specifications, while ensuring that the cleaning scraper 19 is always in contact with the inner wall of the pipe, which is convenient for cleaning.

[0037] In this utility model, the driving component includes a connecting column 26, which is fixedly connected to the telescopic square column 8. Both ends of the connecting column 26 are provided with driving seats 27, and the front and rear ends of the driving seats 27 are provided with driving wheels 28.

[0038] In the above technical solution, by simultaneously setting drive seats 27 at both ends of the connecting column 26, and setting drive wheels 28 at both the front and rear ends of the drive seats 27, the stability of the device moving in the pipeline is improved while the drive seats 27 can drive the device to move.

[0039] In this invention, a detection camera 29 is provided on the end face of the fixed shell 3 away from the cleaning component.

[0040] The working principle of the rainwater and sewage pipe damage detection device of this utility model is as follows:

[0041] In use, first align the cleaning component of the device with the pipe opening and insert it into the pipe opening. The inclined pressure plate 20 abuts against the inner wall of the pipe, and the spring 24 is compressed. Continue to insert it into the pipe opening until the drive seat 27 is fully inserted into the pipe. Then, the dual-axis motor 6 is started by controlling the external controller, which drives the telescopic square column 8 to move until the drive wheel 28 abuts against the inner wall of the pipe. At this time, the drive seat 27 and drive motor 16 are started simultaneously by controlling the external controller. The drive seat 27 drives the drive wheel 28 to rotate, and the drive motor 16 drives the rotating plate 18 to rotate. While moving, it can clean the stains on the inner wall of the pipe. Afterwards, the detection camera 29 can take pictures of the inner wall of the pipe.

[0042] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
