Description

Technical Field

[0001] This utility model relates to the field of lifting mechanism technology, and in particular to a detection device for municipal pipelines. Background Technology

[0002] Municipal pipeline inspection devices are specialized equipment used to inspect and assess the internal condition of underground pipelines for urban water supply, drainage, gas, and heating. Their core function is to obtain information on structural damage, blockages, corrosion, and leaks inside the pipelines through various technical means, providing data support for pipeline maintenance, repair, and management.

[0003] Closed-circuit television (CCTV) inspection devices use a crawler that enters the pipeline via a wheeled or tracked moving mechanism. The camera rotates to capture images of the inner wall and transmits them to a ground terminal in real time. In contrast, traditional inspection devices often require manual pulling of a rope to place the inspection device into the pipeline. The inspection device itself is quite heavy, and the staff needs to apply a large amount of pulling force continuously. This not only results in high labor intensity but may also cause the inspection device to shake when it hits the pipe wall during placement, affecting the inspection accuracy. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Traditional detection devices often require manual pulling of a rope to place the detection body into the pipe. The detection device itself is heavy, and workers need to continuously apply a large pulling force, which is not only labor-intensive but may also cause the detection body to shake when it hits the pipe wall during placement, affecting the detection accuracy. This invention provides a detection device for municipal pipelines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detection device for municipal pipelines, comprising a detection device body, a hook engaged with the outer surface of the detection device body, a pull rope fixedly connected to the outer surface of the hook, a rotating rod fixedly connected to the outer surface of the pull rope, a rope-blocking plate fixedly connected to the outer surface of the rotating rod, a first gear fixedly connected to the outer surface of the rotating rod, a second gear meshing with the outer surface of the first gear, a rotating handle fixedly connected to the inner wall of the second gear, a bearing fixedly connected to the outer surface of the rotating rod, a first bracket fixedly connected to the outer surface of the bearing, a triangular plate fixedly connected to the outer surface of the first bracket, a through hole formed in the inner wall of the triangular plate, a second bracket fixedly connected to the outer surface of the triangular plate, and a rotating wheel rotatably connected to the inner wall of the second bracket.

[0006] In a preferred embodiment, a second connector is fixedly connected to the outer surface of the triangular plate, a first bolt is threadedly connected to the inner wall of the second connector, a first connector is rotatably connected to the outer surface of the first bolt, a fixing rod is fixedly connected to the outer surface of the first connector, a fixing member is fixedly connected to the outer surface of the fixing rod, a sliding member is slidably connected to the inner wall of the fixing member, a trapezoidal member is fixedly connected to the outer surface of the sliding member, and a second bolt is threadedly connected to the inner wall of the fixing member.

[0007] In a preferred embodiment, the outer surface of the second bolt is rotatably connected to the outer surface of the slide, and the outer surface of the slide is slidably connected to the outer surface of the triangular plate.

[0008] In a preferred embodiment, the outer surface of the pull rope is slidably connected to the inner wall of the wheel, and the outer surface of the wheel is rotatably connected to the outer surface of the triangular plate.

[0009] In a preferred embodiment, the outer surface of the first gear is rotatably connected to the inner wall of the first bracket.

[0010] In a preferred embodiment, the outer surface of the first connector is rotatably connected to the inner wall of the second connector.

[0011] In a preferred embodiment, the outer surface of the first gear is meshed with the outer surface of the second gear.

[0012] In a preferred embodiment, the outer surface of the handle is rotatably connected to the outer surface of the triangular plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention utilizes the meshing transmission of the first and second gears to amplify and transmit the operating force of the handle to the rotating rod, enabling easy release and retraction of the pull rope. Compared to directly pulling the rope, the gear transmission reduces manpower consumption, especially in long-distance pipeline inspection or when the device is heavy, significantly reducing the operational intensity of the staff. By adjusting the angle of the first connecting piece around the first bolt, the relative angle between the fixed rod and the triangular plate can be changed. Combined with the sliding of the sliding piece within the fixed piece and the fixing of the second bolt, the distance between the trapezoidal piece and the center of the device can be flexibly adjusted. The combination of these two features allows the device to be adapted to municipal pipelines with different inner diameters. Attached Figure Description

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.

[0023] Example 1

[0024] like Figures 1-5As shown, this utility model provides a technical solution: a testing device for municipal pipelines, comprising a testing device body 1, a hook 2 engaged with the outer surface of the testing device body 1, a pull rope 3 fixedly connected to the outer surface of the hook 2, the outer surface of the pull rope 3 slidably connected to the inner wall of a rotating wheel 11, the outer surface of the rotating wheel 11 rotatably connected to the outer surface of a triangular plate 9, a rotating rod 4 fixedly connected to the outer surface of the pull rope 3, a rope-blocking plate 5 fixedly connected to the outer surface of the rotating rod 4, a first gear 12 fixedly connected to the outer surface of the rotating rod 4, and the outer surface of the first gear 12 rotatably connected to the inner wall of a first support 6. The outer surface of the first gear 12 is meshed with the outer surface of the second gear 13. The outer surface of the first gear 12 is meshed with the second gear 13. The inner wall of the second gear 13 is fixedly connected to the rotating handle 8. The outer surface of the rotating handle 8 is rotatably connected to the outer surface of the triangular plate 9. The outer surface of the rotating rod 4 is fixedly connected to the bearing 7. The outer surface of the bearing 7 is fixedly connected to the first bracket 6. The outer surface of the first bracket 6 is fixedly connected to the triangular plate 9. The inner wall of the triangular plate 9 has a through hole 14. The outer surface of the triangular plate 9 is fixedly connected to the second bracket 10. The inner wall of the second bracket 10 is rotatably connected to the rotating wheel 11.

[0025] In this embodiment, a hook 2 is designed so that its hook rests on the surface of the detection device body 1, facilitating the gripping of the detection device body 1. One end of a pull rope 3 is fixedly connected to the surface of the hook 2, and the pull rope 3 uses its own properties to grip the hook 2. The other end of the pull rope 3 is fixed to the surface of the rotating rod 4 for easy storage of the pull rope 3. A rope-blocking plate 5 is fixed to the surface of the rotating rod 4 to prevent the pull rope 3 from getting caught in the gears when storing it. A first gear 12 is fixed to the surface of the rotating rod 4 to transmit power to the rotating rod 4, driving the rotating rod 4 to wind up the pull rope 3 and pull the hook 2. A second gear 13 meshes with the first gear 12, facilitating the second gear 13 to drive the first gear 12. The handle 8 is fixedly connected to the inner wall of the device, which is convenient for the operator to operate and rotate the second gear 13. The first gear 12 and the rotating rod 4 are fixed to the inner wall of the bearing 7, which is convenient for fixing to the inner wall of the first bracket 6, and thus fixed to the surface of the triangle plate 9. The through hole 14 opened in the inner wall of the triangle plate 9 is convenient for the pull rope 3 to pass through the through hole 14 and pull the hook 2. The second bracket 10 is fixedly connected to the surface of the triangle plate 9, which is convenient for the inner wall to rotate and connect to the rotating wheel 11. The inner wall of the rotating wheel 11 provides a guide rail for the pull rope 3, so that the transmission is on the same point, converting sliding friction into rolling friction, reducing movement resistance, and at the same time helping to maintain the stable posture of the device, ensuring that the main body of the detection device 1 moves smoothly in the pipeline, which is convenient for detection operations.

[0026] Example 2

[0027] like Figures 1-5As shown, a second connector 19 is fixedly connected to the outer surface of the triangle 9. A first bolt 20 is threadedly connected to the inner wall of the second connector 19. A first connector 15 is rotatably connected to the outer surface of the first bolt 20. The outer surface of the first connector 15 is rotatably connected to the inner wall of the second connector 19. A fixing rod 16 is fixedly connected to the outer surface of the first connector 15. A fixing member 17 is fixedly connected to the outer surface of the fixing rod 16. A slider 21 is slidably connected to the inner wall of the fixing member 17. A trapezoidal member 18 is fixedly connected to the outer surface of the slider 21. A second bolt 22 is threadedly connected to the inner wall of the fixing member 17. The outer surface of the second bolt 22 is rotatably connected to the outer surface of the slider 21. The outer surface of the slider 21 is slidably connected to the outer surface of the triangle 9.

[0028] In this embodiment, the second connector 19, which is fixedly installed at the bottom of the triangular plate 9, facilitates rotational connection with the first connector 15. With the tightening of the first bolt 20, the support leg can be adjusted to a suitable opening and closing angle. The fixing rod 16, which is fixed on the outer surface of the first connector 15, provides a guide rail for the slide 21. The fixing member 17 and the second bolt 22 facilitate the slide 21 to slide to a suitable height and then be fixed. The trapezoidal member 18, which is fixed to the slide 21, enhances the overall support stability of the device.

[0029] Working principle:

[0030] like Figures 1-5 As shown, the hook 2 is used to hold the main body 1 of the detection device. The slider 21 is adjusted to a suitable height, and the second bolt 22 is tightened to fix it. The first connecting piece 15 is rotated to a suitable angle and the first bolt 20 is tightened. The operator applies force by rotating the handle 8. Since the handle 8 is fixedly connected to the second gear 13, the second gear 13 will rotate with the handle 8. Since the second gear 13 meshes with the first gear 12, the first gear 12 will be driven to rotate. The first gear 12 is fixedly connected to the rotating rod 4. The rotating rod 4 rotates with the first gear 12, which in turn drives the pull rope 3 wrapped on the rotating rod 4 to be released. The pull rope 3 is connected to the main body 1 of the detection device through the hook 2. The loosening of the pull rope 3 will pull the main body 1 of the detection device to the bottom of the municipal pipeline well. The handle is slowly rotated until the main body 1 of the detection device falls to the bottom of the pipeline well. When it is necessary to remove the main body 1 of the detection device, the operation can be reversed.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
