Description

Technical Field

[0001] The utility model relates to the technical field of robots, and more specifically, to a pipeline detection robot. Background Art

[0002] The pipeline internal inspection robot is a high-tech product that is mainly used to detect the internal conditions of pipelines, including pipeline damage, blockage, leakage, breakage, etc.

[0003] An existing patent (publication number: CN214503387U) discloses a microrobot for internal inspection of municipal pipelines. When the device casing overturns, the device's four sets of anti-skid wheels can switch to another anti-skid wheel for movement, ensuring that the microrobot can still move normally even when it overturns.

[0004] However, when the above device is in use, since the distance between the anti-skid wheels is fixed and cannot be adjusted, the device can only move inside a pipe with a fixed diameter, which reduces the applicability of the device.

[0005] To this end, we propose a pipeline inspection robot to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a pipeline inspection robot to solve the problem that the distance between the anti-skid wheels is fixed and cannot be adjusted, resulting in the device being able to move only inside a pipe of a fixed diameter, reducing the applicability of the device.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a pipeline inspection robot, comprising a shell, a plurality of movable components are arranged around the outer wall of the shell, the movable components include a pair of connecting seats, the connecting seats are respectively fixed to the edges at both ends of the outer wall of the shell, a bidirectional screw rod is rotatably connected between the connecting seats, both ends of the outer wall of the bidirectional screw rod are threadedly connected to a moving block, the top of the moving block is rotatably connected to an adjusting rod, the center of the bidirectional screw rod is fixedly connected to a mounting frame, both ends of the mounting frame are rotatably connected to a moving rod, a connecting groove is opened in the center of the moving rod, the end of the adjusting rod is rotatably connected to the connecting groove, and the end of the moving rod is rotatably connected to a driving wheel.

[0008] Preferably, the bottom of the moving block is slidably connected to the outer wall of the shell.

[0009] Preferably, the movable rods are V-shaped.

[0010] Preferably, a driving motor is fixedly connected to the interior of the end portion of the movable rod, and an output end of the driving motor is fixed to a driving wheel.

[0011] Preferably, a camera is fixedly connected to one end of the shell, and an adjustment component is provided at the other end of the shell.

[0012] Preferably, the adjustment component includes a self-locking motor, which is fixed to one end inside the shell, and the output end of the self-locking motor is fixedly connected to a rotating shaft, and one end of the rotating shaft passes through the shell and is fixedly connected to a driving gear.

[0013] Preferably, one end of the bidirectional screw is fixedly connected to a driven gear, and the driving gear and the driven gear are meshed with each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model starts a self-locking motor to drive the rotating shaft, driving gear, driven gear, and bidirectional screw to rotate. The bidirectional screw drives the moving blocks to move closer to (or away from) each other. At the same time, the moving block drives the position of the adjusting rod to change. Since the length of the adjusting rod is fixed, the adjusting rod will push the angle of the moving rod to change. At this time, the moving rod will drive the driving wheel to move and change the distance between the driving wheels. This makes it suitable for the inside of pipes of different sizes, thereby improving the applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

It belongs to the common knowledge in this field and is only used without improvement. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0023] In the process of inspecting the inside of a pipeline, a robot is needed. The utility model provides a pipeline inspection robot, which is specially used for inspection operations inside a pipeline.

[0024] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To the attached Figure 4 As shown, an embodiment of the present invention provides a pipeline inspection robot, including a shell 1, and a plurality of moving components 3 are arranged around the outer wall of the shell 1. The moving component 3 includes a pair of connecting seats 301, and the connecting seats 301 are respectively fixed to the edges of the two ends of the outer wall of the shell 1. A bidirectional screw rod 302 is rotatably connected between the connecting seats 301, and both ends of the outer wall of the bidirectional screw rod 302 are threadedly connected to a moving block 303. The top of the moving block 303 is rotatably connected to an adjusting rod 304. The center of the bidirectional screw rod 302 is fixedly connected to a mounting bracket 305, and both ends of the mounting bracket 305 are rotatably connected to a moving rod 306. The center of the moving rod 306 is provided with a connecting groove 307, and the end of the adjusting rod 304 is rotatably connected to the connecting groove 307. The end of the moving rod 306 is rotatably connected to a driving wheel 308. The bottom of the moving block 303 is slidably connected to the outer wall of the shell 1. The moving rods 306 are V-shaped. The inside of the end of the moving rod 306 is fixedly connected to a driving motor, and the output end of the driving motor is fixed to the driving wheel 308.

[0026] In this embodiment, when movement is required inside pipes of different sizes, the moving blocks 303 are driven to move closer (or farther away) from each other by rotating the bidirectional screw rod 302. At the same time, the moving blocks 303 drive the position of the adjusting rod 304 to change. Since the length of the adjusting rod 304 is fixed, the adjusting rod 304 will push the angle of the moving rod 306 to change. At this time, the moving rod 306 will drive the driving wheel 308 to move and change the distance between the driving wheels 308, so that it is suitable for the inside of pipes of different sizes, thereby improving the applicability of the device.

[0027] One end of the shell 1 is fixedly connected to the camera 2, and the other end of the shell 1 is provided with an adjustment component 4, which includes a self-locking motor 401. The self-locking motor 401 is fixed to one end inside the shell 1, and the output end of the self-locking motor 401 is fixedly connected to the rotating shaft 402. One end of the rotating shaft 402 passes through the shell 1 and is fixedly connected to the driving gear 403. One end of the bidirectional screw rod 302 is fixedly connected to the driven gear 404, and the driving gear 403 and the driven gear 404 are meshed with each other.

[0028] In this embodiment, by starting the self-locking motor 401 to drive the rotating shaft 402 to rotate, the rotating shaft 402 drives the driving gear 403 to rotate, the driving gear 403 drives the driven gear 404 to rotate, and the driven gear 404 drives all the bidirectional screw rods 302 to rotate, thereby realizing synchronous adjustment of the moving component 3.

[0029] The working process of this utility model is as follows:

[0030] First, according to the internal size of the pipeline, the self-locking motor 401 is started to drive all the bidirectional screw rods 302 to rotate; then, the bidirectional screw rods 302 drive the moving blocks 303 to move closer to (or away from) each other; then, the moving blocks 303 drive the adjusting rod 304 to move, and the adjusting rod 304 pushes the moving rod 306 to change the distance between the driving wheels 308 to the corresponding internal size of the pipeline; finally, the driving wheel 308 is placed inside the pipeline, and the driving motor is started to move the device. At the same time, the monitoring operation is completed using the camera 2.

[0031] It should be emphasized that temperature sensors, humidity sensors and other existing technologies can be installed in the housing 1 of the device to achieve more comprehensive pipeline detection operations.
