Description

Technical Field

[0001] The utility model relates to the technical field of pipeline breakpoint measurement, in particular to an auxiliary device for pipeline breakpoint measurement. Background Art

[0002] Existing communication pipelines, such as those in highways, often use PE pipes; the penetration of communication pipelines is very important for highway construction because communication pipelines undertake data transmission and power supply for all equipment on the highway. If the communication pipeline cannot be constructed, the entire highway monitoring and toll collection systems will not be able to work together. At the same time, the communication pipeline also has the longest construction period in highway electromechanical construction. Therefore, ensuring the construction of the communication pipeline is very important. Currently, the construction of communication pipelines mainly includes key steps such as PE pipe fusion welding, backfilling, and cable threading. Due to complex construction environments, many cross-operation surfaces, and factors such as the ability level of fusion welding personnel and the rolling of passing vehicles after backfilling, communication pipelines are prone to breakpoints after laying. These breakpoints must be located and then excavated, and then the PE pipes are re-fusion welded and repaired.

[0003] Existing pipeline breakpoint detection methods generally use a wire to connect a wind resistor, such as an object that can move along the inside of the pipeline driven by wind, like a table tennis ball or a plastic bottle. Subsequently, the wind resistor is blown into the pipeline. When the wind resistor reaches the breakpoint and stops, the length of the wire pulled out can represent the distance between the breakpoint and the pipeline entrance. Subsequently, workers can be dispatched to the designated location to repair the breakpoint. However, measuring the length of the wire requires pulling the wire and the wind resistor out of the pipeline, and then re-blowing the wire and the wind resistor into the pipeline after measurement. Moreover, manually measuring the length of the flexible wire is also rather cumbersome. The length of existing communication pipelines in highways is generally more than ten times the length of the highway. If the wire blowing speed is ignored, the manhole spacing on the highway is set at 500 - 1000 m, and the manual wire retracting speed is calculated at 1 m / s, then the time for one wire retraction is 8 - 16 minutes, and the time for manually measuring the length of the thin wire once before and after pulling it out is about 20 minutes. And if there are multiple breakpoints within a certain distance, then it is necessary to multiply by the multiple of the breakpoints on this basis. It can be seen that the existing breakpoint detection methods will waste a lot of time on the operations of repeatedly blowing in and pulling out the wire, with cumbersome steps, low efficiency, and high time costs. There is an urgent need for a more convenient breakpoint detection method. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the technical problems in the existing pipeline breakpoint detection methods, such as the need for repeatedly blowing in, pulling out, and manually measuring the wire, with cumbersome steps, low efficiency, and high time costs, and to provide an auxiliary device for pipeline breakpoint measurement.

[0005] In a first aspect, the utility model provides an auxiliary device for pipeline breakpoint measurement, comprising:

[0006] Airframe;

[0007] A runner, which is rotatably connected to the airframe and has a wire groove extending along the circumference of the runner, so that the pull wire can pass through the wire groove and drive the runner to rotate when pulled;

[0008] An encoder, which is connected to the runner and is used to output a signal of the rotation angle of the runner;

[0009] A calculation module, which is communicatively connected to the encoder and can receive the signal of the encoder and calculate the rotation angle of the runner;

[0010] A display device, which is communicatively connected to the calculation module and is used to display the calculation result of the calculation module.

[0011] When the main body of this solution is in use, first bypass the pull wire connected to the air resistor around the runner, and then use the wind force to blow the air resistor into the pipeline, which can drive the pull wire to penetrate into the pipeline together with the air resistor. Then, the pull wire drives the runner to rotate, and the moving distance of the pull wire matches the rotational linear distance at the wire groove of the runner; the rotation information of the runner, such as rotation angle, rotation direction, rotation speed, etc., will be converted into an electrical signal by the rotary encoder and input into the calculation module. According to the rotation angle of the runner and the distance between the wire groove and the axis of the runner, the rotational linear distance at the wire groove of the runner can be calculated, that is, the moving distance of the pull wire; then, the calculation result is displayed through the display device, which can facilitate the staff to directly obtain the distance between the break point and the pipeline entrance, without repeatedly blowing in, pulling out, and manually measuring the pull wire, thus saving a large amount of time and labor costs and improving the measurement efficiency.

[0012] Preferably, a speed reduction mechanism is further provided between the encoder and the runner structure.

[0013] This solution can make the encoder operate under low-speed conditions. On the one hand, it can utilize the good low-speed response characteristics of the encoder to ensure the measurement accuracy. On the other hand, it can also reduce the working load of the encoder and improve the service life of the encoder.

[0015] This solution recommends one specific form of the speed reduction mechanism, which has the advantages of compact structure, long service life, and large load-bearing capacity. It can reduce the overall volume and weight of this solution and improve the service life of this solution.

[0016] Preferably, a stop structure is provided at one end of the wire groove far from the center of the runner, and the stop structure is used to prevent the pull wire from slipping out of the wire groove.

[0017] This solution can prevent the pull wire from slipping out of the wire groove.

[0018] Preferably, an anti-slip layer is provided in the wire groove.

[0019] This solution can inhibit the situation where the wire being pulled slides relative to the wire groove, resulting in a decrease in the accuracy of the measurement result.

[0020] Preferably, at least two protective baffles are provided on the machine body at intervals, and the rotating wheel is located between two adjacent protective baffles.

[0021] This solution can protect the rotating wheel through the protective baffle, reduce the interference of the external environment on the operation of the rotating wheel, and at the same time can also inhibit the situation where the rotating wheel comes into direct contact with the operator's body, causing injury to the staff.

[0022] Preferably, the encoder is also located between two adjacent protective baffles.

[0023] This solution can protect the encoder through the protective baffle, reduce the interference and damage of the external environment on the encoder.

[0024] Preferably, a cavity structure is provided on the machine body, and the calculation module is located inside the cavity structure.

[0025] This solution can protect the calculation module through the machine body, reduce the interference and damage of the external environment on the calculation module.

[0026] Preferably, a handle is also connected to the machine body.

[0027] This solution can facilitate the staff to hold the machine body by hand.

[0028] Preferably, the display device includes a liquid crystal display.

[0029] This solution recommends a specific structural form of the display device, which has the advantages of low energy consumption, high brightness, and wide viewing angle, and can make this solution more suitable for outdoor use scenarios.

[0030] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0031] The present utility model provides an auxiliary device for measuring the break point of a pipeline. By pulling a wire to drive a rotating wheel to rotate, and obtaining the rotation angle information of the rotating wheel through an encoder, the moving distance of the wire can be automatically calculated by a calculation module and displayed by a display device for the convenience of the staff to read immediately. Therefore, the present utility model no longer needs to repeatedly blow in, pull out, and manually measure the wire, which can save a large amount of time and labor costs and improve the measurement efficiency.
