Description

Technical Field

[0001] The present application relates to the technical field of underground pipeline detection, and in particular to a municipal pipeline network pipeline deformation detection device. Background Art

[0002] Municipal highway projects often include underground pipe networks. The quality of these pipe networks directly determines the proper functioning of many municipal engineering functions. Drainage pipes are the most common type of pipe network. These are non-pressurized pipes that rely on gravity to drain water. The designed flow gradient is a key quality control point during construction, determining whether water can be drained smoothly. Deformation and bending of the pipe material during construction directly impacts changes in the flow gradient, making pipe deformation detection during and after construction a critical task.

[0003] Currently, the more common detection method is: after the pipeline backfill is completed, a settlement observation point is arranged on the top surface of the backfill soil directly above the pipeline, and the pipeline deformation is indirectly reflected by observing the soil settlement.

[0004] This type of backfill settlement observation only indirectly reflects pipeline deformation and does not directly reflect the actual deformation of the pipeline. This is because the measuring instrument cannot directly measure the deformation data collected at the flow surface of the pipeline wall. Even if the backfill does not settle during the measurement period, it is possible that the pipeline has deformed during the backfill layering and rolling and compaction process. This deformation cannot be measured through settlement observation. Summary of the Invention

[0005] The present application provides a municipal pipe network pipe deformation detection device to solve the current problem of low accuracy in underground pipe detection.

[0006] The technical solutions adopted in this application are as follows:

[0007] A municipal pipe network pipe deformation detection device includes a laser emission disk and a target disk;

[0008] The laser emission disk is provided with a laser emitter, and the disk surfaces of the laser emission disk and the target disk are circular.

[0009] In some embodiments, a rotating slide is further included, which is arranged on the laser emitting disk. The center point of the rotating slide is movably connected to the center of the laser emitting disk. The rotating slide rotates around the center of the laser emitting disk. A slider that slides along the rotating slide is provided on the rotating slide, and the laser emitter is fixedly connected to the slider.

[0010] In some embodiments, the target disk is provided with circular scale lines.

[0011] In some embodiments, the target plate is further provided with a cross line, which divides the target plate into four quadrants. The circular scale lines of the target plate are concentric circular ring markings that gradually decrease in radius from the outer edge of the target surface to the center of the target with a radius difference of 1 cm. The diameter of the outermost circular ring line is equal to the diameter of the cross-section of the inner wall of the pipe.

[0012] In some embodiments, the target plate includes embedded legs and a transparent target plate, the number of the embedded legs is at least 2, the outer surface of the embedded legs is set to be an arc shape that fits the inner wall of the pipe, and the embedded legs are set on the transparent target plate near the outer edge of the transparent target plate.

[0013] In some embodiments, the target plate includes a plate body, an edge of the plate body is provided with a connecting portion, the connecting portion is provided with a bolt through hole, and the plate body is fixedly connected to the pipeline via a bolt sleeved in the bolt through hole.

[0014] In some embodiments, a handle is further included, and the handle is disposed on the laser emission disk. The handle and the laser emitter are respectively disposed on the outer side and the inner side of the laser emission disk.

[0015] In some embodiments, a spiral groove and a sliding clip are provided on the laser emitting disk. The spiral groove spirals from the outer edge of the laser emitting disk to the center point of the circle. The bottom of the spiral groove is provided with a groove opening consistent with the spiral of the spiral groove. The sliding clip slides along the groove opening. One end of the sliding clip is exposed to the outside of the laser emitting disk, and the other end of the sliding clip is fixedly connected to the laser emitter through the groove opening.

[0016] In some embodiments, a shooting recorder with a time-lapse recording function is further included. The shooting recorder is set on the target plate and is used to shoot the position and trajectory of the laser light spot of the laser emitter on the target plate.

[0017] In some embodiments, the target plate is a variable diameter target plate, which includes a target body and a target surface. The target body is trumpet-shaped, and the target surface is made of fiber cloth. The target body is buckled on the end of the pipe, and a bolt through hole is provided on the target body. The target surface is fixed to the pipe and tightened by a bolt installed in the bolt through hole.

[0018] This application installs a laser emitting disk and a target disk at the ports of adjacent inspection well pipes, and the laser emitting disk projects the laser onto the target disk through the pipe. Ideally, all vertical sections of the pipeline are equal and perpendicular to the pipeline axis, and the laser can be projected to any position of the target surface that is equal and parallel to the vertical section of the pipeline. If the pipeline is locally deformed, the laser is blocked at the deformed position and cannot be projected onto the target surface. When the laser passes through the critical position of the deformation, the laser is projected onto the target surface, and the position of the laser point on the target surface can indicate the degree of local deformation of the pipeline. By moving the position of the laser emitter on the laser emitting disk, the position of the laser point projected onto the target surface at multiple different positions can be used for pipeline deformation quality detection in pipeline engineering.

[0031] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0032] Pipeline projects usually have inspection wells. The pipelines between the inspection wells have a fixed slope and the pipeline axis is a straight line. The device uses the physical property of laser propagation in a straight line to detect the deformation of the pipeline between the two inspection wells.

[0033] A laser transmitter and target disk are installed at the two ports of the pipeline between two adjacent inspection wells. Workers at both ends communicate using walkie-talkies. The laser transmitter slides from the outermost edge of the pipeline section toward the center. If the pipeline is not deformed, the laser will be projected onto the target at the corresponding cross-section. If local deformation occurs, the laser will not reach the target. The laser transmitter continues to move toward the center until it reaches the target. Workers at both ends then record the positions of the laser points on the laser transmitter and target, respectively. The comparison of the two recorded values represents the amount of pipeline deformation. By collecting and comparing data from multiple locations using three laser transmitters, a more accurate understanding of pipeline deformation can be achieved.

[0034] See also Figure 1 , which is a schematic diagram of the layout structure of the laser emission disk according to an embodiment of the present application.

[0035] The present application provides a municipal pipe network pipe deformation detection device, comprising a laser emission disk 1 and a target disk 2;

[0036] The laser emitting disk 1 is provided with a laser emitter 11 , and the disk surfaces of the laser emitting disk 1 and the target disk 2 are circular.

[0037] refer to Figure 2-Figure 4 In this embodiment, the laser emitter 11 is connected to the laser emitting disk 1. The connection method can be a fixed connection or a movable connection. The laser emitting disk 1 only provides a fulcrum for the laser emitter 11 to emit a laser beam along the axial direction of the pipeline toward the target disk 2. The light spot of the beam falls on the target disk 2. By observing and measuring the trajectory of the light spot on the target disk 2, it is possible to intuitively determine whether the pipeline is deformed. By accurately measuring the distance between the light spot and the edge of the pipeline, the accurate value of the pipeline deformation can also be obtained.

[0038] In some embodiments, a rotating slide rail 12 is further included. The rotating slide rail 12 is arranged on the laser emitting disk 1. The center point of the rotating slide rail 12 is movably connected to the center of the laser emitting disk 1. The rotating slide rail 12 rotates around the center of the laser emitting disk 1. A slider 13 is provided on the rotating slide rail 12 and slides along the rotating slide rail 12. The laser emitter 11 is fixedly connected to the slider 13.

[0039] refer to Figure 1 In this embodiment, the rotating slide 12 can rotate freely 360 degrees around the center point. In some embodiments, the length of the rotating slide 12 is set to the length of the inner diameter of the pipeline, and then a slider 13 is set on the rotating slide 12 to slide along the rotating slide 12. The laser emitter 11 is fixed on the slider 13. By sliding the slider 13 and coordinating the rotation of the rotating slide 12, the laser emitter 11 can be fixed at any position on the disk surface, thereby realizing the emission of laser beams without blind spots and achieving all-round deformation measurement of the pipeline.

[0040] In some embodiments, the target plate 2 is provided with circular scale lines.

[0041] In some embodiments, the target plate 2 is further provided with a crosshair, which divides the target plate 2 into four quadrants. The circular scale lines of the target plate 2 are concentric circular ring markings that gradually decrease in radius from the outer edge of the target surface 25 to the center of the target with a radius difference of 1 cm. The diameter of the outermost circular ring line is equal to the diameter of the cross-section of the inner wall of the pipe.

[0042] refer to Figure 2 , a circular scale line is set on the target plate 2. By comparing the landing point of the laser light spot on the scale line, the deformation of the pipeline can be accurately measured.

[0043] In some embodiments, the target plate 2 includes an embedded leg 22 and a transparent target plate 21, the number of the embedded leg 22 is at least 2, the outer surface of the embedded leg 22 is set to be an arc shape that fits the inner wall of the pipe, and the embedded leg 22 is set on the transparent target plate 21 near the outer edge of the transparent target plate 21.

[0044] See also Figure 3 and Figure 4 In order to facilitate the fixation of the target plate 2 on the pipeline, an embedded leg 22 is provided and snapped into the pipeline. The reasonable setting of the distance between the embedded leg 22 can make the embedded leg 22 more secure on the pipeline.

[0045] In some embodiments, the target plate 2 includes a plate body, an edge of the plate body is provided with a connecting portion, the connecting portion is provided with a bolt through hole, and the plate body is fixedly connected to the pipeline via bolts 26 sleeved in the bolt through holes.

[0046] See also Figure 5 By fixing the disc body to the pipeline by bolts 26, the target disc 2 is firmly connected to the pipeline and is not easy to loosen or shake, which is beneficial to improving the efficiency and accuracy of measurement.

[0047] See also Figure 1 In some embodiments, a handle 14 is further included. The handle 14 is arranged on the laser emitting disk 1. The handle 14 and the laser emitter 11 are respectively arranged on the outer side and the inner side of the laser emitting disk 1.

[0048] See also Figure 6 In some embodiments, the laser emitting disk 1 is provided with a spiral groove 15 and a sliding buckle. The spiral groove 15 spirals from the outer edge of the laser emitting disk 1 to the center point. The bottom of the spiral groove 15 is provided with a groove opening 16 that is consistent with the spiral groove 15. The sliding buckle slides along the groove opening 16, with one end of the sliding buckle exposed outside the laser emitting disk 1, and the other end of the sliding buckle is fixedly connected to the laser emitter 11 through the groove opening 16. By manually controlling the sliding buckle to move along the groove opening 16, the laser emitter 11 is driven to move on the laser emitting disk 1, realizing multi-position measurement of the laser beam and improving measurement efficiency.

[0049] See also Figure 6 In some embodiments, a camera recorder 23 with a time-lapse recording function is further included. The camera recorder 23 is disposed on the target plate 2 and is used to record the position and trajectory of the laser spot of the laser emitter 11 on the target plate 2. In this embodiment, because construction workers are often limited by the working space within the underground pipeline, it is difficult to operate the work. Using the camera recorder 23 for machine photography instead of the human eye can reduce the impact of site constraints. In addition, the quality of photography is generally higher than that of visual recognition. It can be imagined that by connecting a computer to the camera recorder 23 and utilizing a recognition algorithm, the accuracy of detection and recognition can be further improved.

[0050] See also Figure 7In some embodiments, the target disk 2 is a variable-diameter target disk 2, comprising a target body 24 and a target surface 25. The target body 24 is trumpet-shaped, and the target surface 25 is made of fiber cloth. The target body 24 is fastened to the end of the pipe and provided with bolt holes. The target surface 25 is secured to the pipe and tightened using bolts inserted into the bolt holes. In this embodiment, the target surface 25 is made of fiber cloth, which has good plasticity and can be arbitrarily adjusted by applying tension to the target surface 25 to receive the light beam spot. By pre-setting bolt holes in the target body 24, the target body 24 and target surface 25 are simultaneously secured to the outer wall of the pipe using bolts, and the target surface 25 is tensioned, which facilitates obtaining the material plane of the light spot. This provides strong support for subsequent measurement of the light spot distance to determine pipe deformation and to measure the amount of pipe deformation.

[0051] In actual application of this application, by installing a laser emitting disk and a target disk at the ports of adjacent inspection well pipes, the laser emitting disk projects the laser onto the target disk through the pipe. In an ideal state, all vertical sections of the pipeline are equal and perpendicular to the pipeline axis. The laser can be projected to any position of the target surface that is equal and parallel to the vertical section of the pipeline. If the pipeline is locally deformed, the laser is blocked at the deformed position and cannot be projected onto the target surface. When the laser passes through the critical position of the deformation, the laser is projected onto the target surface, and the position of the laser point on the target surface can indicate the degree of local deformation of the pipeline. By moving the position of the laser emitter on the laser emitting disk, the position of the laser point projected onto the target surface at multiple different positions can be used for pipeline deformation quality detection of pipeline engineering.

[0052] The municipal pipe network pipe deformation detection device of the present application includes a laser emitting disk and a target disk; a laser emitter is provided on the laser emitting disk, and the disk surfaces of the laser emitting disk and the target disk are circular. In some embodiments of the present application, by respectively providing a laser emitting disk and a target disk at the two ends of the underground pipe, the optical principle of laser irradiation is utilized to more intuitively detect the deformation of the pipe and directly reflect the change in the slope of the water flow surface on the inner wall of the pipe. The present application uses laser irradiation to check for pipe deformation, thereby avoiding to a certain extent the problem of pipe deformation affecting the slope of the water flow surface, which is beneficial to the normal realization of the drainage function of the pipe during use.
