Description

Technical Field

[0001] The present invention relates to the technical field of drainage pipeline detection, in particular to an underground pipeline inner diameter detection device. Background Art

[0002] In pipeline detection, accurate pipe diameter measurement is crucial for more accurately determining the buried depth of pipelines. This provides construction companies with precise data, effectively preventing damage to pipelines during construction. During pipeline inspection, precise measurement of the pipeline's inner diameter allows pipeline robots to select the appropriate wheelbase for entry, enabling them to better navigate within the pipeline and detect defects. Furthermore, accurate measurement of the pipeline's inner diameter provides precise data for subsequent pipeline repairs, helping to order appropriate repair materials and avoid waste due to unsuitable materials, which in turn increases costs.

[0003] Currently, the traditional L-shaped drainage rod is commonly used to measure the inner diameter of underground pipelines. This rod is hooked inside the pipe and measures the pipe's top and bottom heights to calculate the diameter. However, since the pipe's diameter is larger at one end than the pipe itself, the true diameter cannot be measured if the pipe's opening is also a casing. Furthermore, this measurement method is less accurate. Furthermore, residual dirt easily adheres to the inner wall of the sewage pipe, affecting the measurement of the pipe's inner diameter and resulting in inaccurate values. Therefore, a device for detecting the inner diameter of underground pipelines is needed to address these issues. Summary of the Invention

[0030] A device for detecting the inner diameter of an underground pipeline comprises: a telescopic rod 1, the lower end of the telescopic rod 1 being connected to a right-angle connector 2, the end of the right-angle connector 2 being connected to a transverse tube 3, so that the telescopic rod 1 and the transverse tube 3 form an "L"-shaped structure; the telescopic rod 1 comprises a plurality of movably nested rod bodies 11, the ends of the rod bodies 11 being equipped with locking seats 12 for fixing the positions of the rod bodies 11; by loosening the locking seats 12, the corresponding rod bodies 11 can be telescopically adjusted, thereby adjusting the overall length of the telescopic rod 1, facilitating the detection of pipelines at different depths underground, and improving the applicability of the device.

[0031] The mounting frame 4 is connected to the end of the transverse tube 3. A plurality of linear drives 5 are equidistantly installed on the side circumference of the mounting frame 4. The linear drive 5 is an electric cylinder that can accurately control the elongation length of the driving end, making the measured data more accurate.

[0032] The detection head 6 is installed at the output end of the linear drive 5. The detection head 6 includes a supporting component and a cleaning component. The supporting component is used to control the linear drive 5 to stop moving after contacting the inner wall of the pipe, and the cleaning component is used to clean the supporting part of the inner wall of the pipe.

The top of the supporting block 61 is embedded with a button switch 62. The button switch 62 is squeezed and pressed after contacting the inner wall of the pipe. There are more than 3 supporting assemblies, and 3 are provided in this embodiment. When all 3 supporting blocks 61 contact the inner wall of the pipe and all the button switches 62 are pressed, the linear drive 5 stops running and readings can be taken at this time.

[0034] The cleaning assembly includes a connecting rod 63, a connecting shaft 64 and a torsion spring 65. Two connecting rods 63 are installed on each of the support blocks 61. One end of the connecting rod 63 is rotatably connected to the support block 61 through the connecting shaft 64. A torsion spring 65 is provided on the connecting shaft 64. The setting of the torsion spring 65 can enable the two connecting rods 63 to move closer to each other and reset and rotate. The two connecting rods 63 form a "V"-shaped structure. The setting of the "V"-shaped structure can enable the two connecting rods 63 to rotate away from each other when squeezed.

[0035] The other end of the connecting rod 63 is rotatably connected to a cleaning block 66, and the upper end surface of the cleaning block 66 is provided with cleaning teeth 67.

[0036] The present invention also includes a display screen 10, which is mounted on the upper end of the telescopic rod 1 through an adjustment assembly and is used to display measurement data; the adjustment assembly includes a mounting platform 7, a rotating seat 8 and an angle adjustment bracket 9, the mounting platform 7 is fixedly connected to the upper end of the telescopic rod 1, the mounting platform 7 is provided with a rotating seat 8, the rotating seat 8 is installed with an angle adjustment bracket 9, and the display screen 10 is mounted on the angle adjustment bracket 9; the direction and pitch angle of the display screen 10 can be adjusted according to usage requirements to facilitate the user to observe the display screen 10.

[0037] The working principle of the present invention is:

[0038] When it is necessary to detect the inner diameter of the underground pipeline, the detection device is first extended into the pipe mouth of the underground pipeline, and the horizontal tube 3 is moved horizontally into the pipeline. Then all the linear drives 5 are controlled to start synchronously, and the linear drive 5 drives the detection head 6 to move synchronously toward the inner wall of the pipeline.

[0039] When the cleaning block 66 contacts the inner wall of the pipe, the linear drive 5 continues to drive, and the cleaning block 66 transmits the extrusion force to the connecting rod 63, so that the two connecting rods 63 rotate away from each other, and the connecting rod 63 drives the cleaning block 66 to move synchronously, so that the cleaning teeth 67 on the cleaning block 66 remove and clean the debris at the detection position on the inner wall of the pipe until the support block 61 contacts and supports the inner wall of the pipe.

[0040] When the button switches 62 on all the supporting blocks 61 are pressed and triggered, the linear drive 5 stops driving, readings are taken according to the extended length of the linear drive 5, and the measured values ​​are displayed on the display screen 10 and recorded, thereby completing the detection of the inner diameter of the underground pipeline.
