[0002] Auxiliary devices for drainage pipe inspection play a crucial role in drainage pipe inspection. By stabilizing the pipe, optimizing inspection conditions, and improving operational safety, they ensure the accuracy and efficiency of the inspection work. In drainage pipe inspection, auxiliary devices can fix the pipe to prevent displacement or deformation caused by its own weight, fluid pressure, or external forces. In closed-circuit television inspection, a stable pipe can avoid image jitter and ensure clear inspection images. In sonar inspection, fixing the pipe can reduce the interference of water flow fluctuations on sonar signals and improve inspection accuracy.

[0003] The existing technology still has the following shortcomings:

[0004] 1. Existing auxiliary devices for drainage pipe inspection are bulky and inconvenient to carry. During drainage pipe inspection, it is necessary to stabilize the drainage pipe to improve operational safety and inspection accuracy. However, the existing auxiliary devices are bulky and inconvenient to carry into the pipe.

[0005] 2. Existing auxiliary devices for drainage pipe inspection still have the problem of lacking compatibility with various sizes of drainage pipes. Different sizes and specifications of pipes require different sizes of auxiliary devices, and the existing auxiliary devices have poor versatility. Utility Model Content

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution:

[0026] An auxiliary device for inspecting drainage pipes includes a connecting shaft 1. Three rotating grooves 2 are formed on the outer side of the connecting shaft 1. Each of the three rotating grooves 2 is rotatably connected to a mounting ring 3. A support rod 4 is fixedly connected to the outer side of the mounting ring 3. An adjusting screw 5 is threadedly connected to the end of the support rod 4 away from the mounting ring 3. An adjusting handle 6 is fixedly connected to the top of the adjusting screw 5. A support head 7 is fixedly connected to the top of one of the adjusting handles 6. When the operator rotates one of the adjusting handles 6, the adjusting screw 5 rotates, adjusting the support head 7 to the top of the drainage pipe and ensuring that the support head 7 is tightly pressed against the top of the drainage pipe.

[0027] The other two adjustment handles 6 are fixedly connected to the top of the connecting rods 8. The end of the connecting rod 8 away from the adjustment handle 6 is fixedly connected to the support block 9. The side of the support block 9 away from the connecting rod 8 is fixedly connected to the anti-slip pad 10. When the other two adjustment handles 6 are rotated, the support block 9 is moved away from the mounting ring 3 by the support block 9 until the anti-slip pad 10 touches the inner wall of the drain pipe.

[0028] A magnetic block 11 is fixedly connected to one side of the support block 9. When the present invention is folded up, the magnetic blocks 11 on one side of the two support blocks 9 are attracted together to facilitate the operator's storage.

[0029] A fixing hole 12 is provided in the middle of the connecting shaft 1. A spring 13 is fixedly connected inside the fixing hole 12. A retaining sleeve 14 is fixedly connected to the other end of the spring 13. The retaining sleeve 14 is sleeved on the outside of the connecting shaft 1. Three fixing grooves 15 are provided on the retaining sleeve 14. The fixing grooves 15 are adapted to the support rods 4. The operator pulls the retaining sleeve 14 away from the connecting shaft 1 until the fixing grooves 15 no longer hold the three support rods 4. Then, the position of the three support rods 4 is adjusted so that they are aligned with the three fixing grooves 15 respectively. Then, the operator releases the retaining sleeve 14. The spring 13 drives the retaining sleeve 14 to reset. The three fixing grooves 15 respectively hold the three support rods 4, thus completing the unfolding of this utility model.

[0030] The adjustment handle 6 is equipped with anti-slip texture, and the top of the support head 7 is fixedly connected with a rubber pad. The anti-slip texture reduces slippage when the operator rotates the adjustment handle 6, making it easier to operate. The rubber pad at the top of the support head 7 can make the support head 7 more stable against the inner wall of the drain pipe, resulting in better support.

[0031] The working principle of this utility model is as follows:

[0032] First, the operator pulls the retaining sleeve 14 away from the connecting shaft 1 until the fixing groove 15 no longer holds the three support rods 4. Then, the position of the three support rods 4 is adjusted so that they are aligned with the three fixing grooves 15 respectively. Then, the operator releases the retaining sleeve 14, and the spring 13 drives the retaining sleeve 14 to reset. The three fixing grooves 15 then hold the three support rods 4 respectively, thus completing the unfolding of this utility model. Next, the operator rotates one of the adjusting handles 6, which drives the adjusting screw 5 to rotate, adjusting the support head 7 to the top of the drain pipe and ensuring that the support head 7 is pressed tightly against the top of the drain pipe. Then, the operator rotates the other two adjusting handles 6. By moving the support block 9 away from the mounting ring 3 until the anti-slip pad 10 abuts against the inner wall of the drainage pipe, the present invention can enter the working state and support the drainage pipe. It can be adapted to drainage pipes of various sizes and has good versatility. At the same time, anti-slip pads and rubber anti-slip pads 10 are provided at the contact position with the drainage pipe to prevent slipping during use, which is practical. When storing the present invention, pull the sleeve 14 again and rotate the three support rods 4 into the same fixing groove 15. The magnetic blocks 11 on one side of the two support blocks 9 are attracted together to facilitate storage by the operator and have good portability.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
