Description

Technical Field

[0001] This utility model relates to the field of pipeline measurement technology, specifically an underground pipeline network measurement device. Background Technology

[0002] The pipe diameter in underground pipe networks is selected in accordance with the network's transport capacity. During the inspection of underground pipe networks, it is necessary to measure the pipe diameter. Using tools such as vernier calipers, a circle is drawn on the inside of the pipe, and the maximum size measured is the diameter. However, using measuring equipment can measure more accurate data, making the measurement results more reliable.

[0003] Manual measurement methods are inefficient and prone to errors. Some pipeline measurement devices measure diameter by extending telescopic rods at both ends and having the ends of the rods contact the inner wall of the pipeline. However, since the inner wall of the pipeline is curved, it is impossible to determine whether the ends of the telescopic rods contact the farthest inner wall on either side of the pipe, or whether the intersection of the telescopic rods and the measuring rods is at the center of the circle. This results in significant errors in the measurement data.

[0004] Based on this, an underground pipeline measurement device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this utility model is to provide an underground pipeline network measuring device to solve the problems of low efficiency and large measurement errors in the manual measurement method in the background art. Some pipeline network measuring devices measure the diameter by extending the telescopic rods at both ends and having the ends of the telescopic rods contact the inner wall of the pipeline. However, the inner wall of the pipeline is arc-shaped, making it impossible to determine whether the ends of the telescopic rods contact the farthest inner wall on both sides of the pipe, and it is impossible to determine whether the intersection of the telescopic rod and the measuring rod is at the center of the circle, thus leading to large errors in the measurement data.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An underground pipeline network measuring device includes a housing, a fixed box on the outside of the housing, a connecting shaft on the surface of the housing, the connecting shaft passing through the fixed box, a worm gear located inside the fixed box at the outer end of the connecting shaft, the surface of the connecting shaft being connected to the side wall of the fixed box via a bearing, a worm being located above the worm gear inside the fixed box, one end of the worm being rotatably connected to the side wall of the fixed box, and the other end of the worm being fixedly connected to the output end of a first motor on the inner wall of the fixed box, with the worm and the worm gear meshing with each other, and a movable groove provided on one side of the housing, within which a moving mechanism is provided.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] In one alternative: a bidirectional threaded rod is provided in the movable groove, one end of which is rotatably connected to the inner wall of the movable groove, and the other end of which is fixedly connected to the output end of the second motor on the outside of the housing.

[0010] In one alternative: the moving mechanism includes a connecting rod, which is symmetrically arranged on one side of the housing. A connecting block is provided on one side of the bottom end of the connecting rod. The connecting block is slidably connected in the movable groove, and the connecting block is threadedly rotatably connected to the bidirectional threaded rod.

[0011] In one alternative: the outer end of the connecting rod is provided with a groove, a slider is slidably connected in the groove, the bottom end of the slider is fixedly connected to the bottom surface of the groove by a spring, and a ball is movably connected to the top of the slider.

[0012] In one alternative: a mounting bracket is provided on one side of the housing, and a laser rangefinder sensor is mounted on the mounting bracket, which is located at the center of the housing.

[0013] In one alternative: handles are provided on both sides of the fixed box, and the handles are symmetrically arranged on the two side walls of the fixed box.

[0014] In one alternative: the surface of the fixed box is provided with a control panel, and the control panel is provided with a display screen.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a second motor to drive a bidirectional threaded rod to rotate. During this rotation, the connecting rod moves relative to the second motor, allowing for telescopic adjustment. The ball contacts the inner wall of the pipe network until it stops rolling. At this point, the connecting rod is at its furthest point from the inner wall, improving measurement accuracy. The first motor then drives a worm gear to rotate. The worm gear meshes with a worm wheel, causing the worm wheel to rotate, resulting in synchronous rotation of the housing. This prevents debris on the inner wall of the pipe network from affecting the measurement, ensuring the ball is fully in contact with the inner wall. A laser ranging sensor detects the distance between itself and the inner wall of the pipe network, sending the detection result to the control mainboard for calculation. The result is then displayed on a screen. Attached Figure Description

A worm 6 is located above the worm gear 5 inside the fixed box 2, one end of the worm 6 is rotatably connected to the side wall of the fixed box 2, and the other end of the worm 6 is fixedly connected to the output end of a first motor 7 on the inner wall of the fixed box 2, and the worm 6 and the worm gear 5 mesh with each other. A movable groove 11 is provided on one side of the housing 1, and a moving mechanism is provided in the movable groove 11. The first motor 7 can drive the worm 6 to rotate. Through the meshing of the worm 6 and the worm gear 5, the worm gear 5 is driven to rotate, so that the housing 1 rotates synchronously, preventing debris on the inner wall of the pipeline network from affecting the measurement. The length can be adjusted by the moving mechanism, thereby facilitating the measurement work.

[0024] In one embodiment, such as Figure 3 As shown, a bidirectional threaded rod 12 is provided in the movable groove 11. One end of the bidirectional threaded rod 12 is rotatably connected to the inner wall of the movable groove 11, and the other end of the bidirectional threaded rod 12 is fixedly connected to the output end of the second motor 13 on the outside of the housing 1. Starting the second motor 13 can drive the bidirectional threaded rod 12 to rotate.

[0025] In one embodiment, such as Figure 3 As shown, the moving mechanism includes a connecting rod 14, which is symmetrically arranged on one side of the housing 1. A connecting block 15 is provided on one side of the bottom end of the connecting rod 14. The connecting block 15 is slidably connected in the movable groove 11, and the connecting block 15 is threadedly rotatably connected to the bidirectional threaded rod 12. During the rotation of the bidirectional threaded rod 12, it drives the connecting rod 14 to move relative to each other, so as to perform telescopic adjustment.

[0026] In one embodiment, such as Figure 3 As shown, a groove 16 is provided at the outer end of the connecting rod 14, and a slider 17 is slidably connected in the groove 16. The bottom end of the slider 17 is fixedly connected to the bottom surface of the groove 16 by a spring 18. A ball 19 is movably connected to the top of the slider 17, and the ball 19 can roll along the inner wall of the pipe network.

[0027] In one embodiment, such as Figure 2 As shown, a mounting bracket 20 is provided on one side of the housing 1. A laser rangefinder sensor 21 is mounted on the mounting bracket 20. The mounting bracket 20 is located at the center of the housing 1.

This prevents debris on the inner wall of the pipeline network from affecting the measurement, ensuring that the ball 19 is in complete contact with the inner wall of the pipeline network. The distance between the laser ranging sensor 21 and the inner wall of the pipeline network is detected by the laser ranging sensor 21. The detection result is sent to the control mainboard for calculation and is displayed on the display screen 10.
