Description

Technical Field

[0001] This utility model relates to the field of coal mine safety detection technology, and in particular to a defect detection device adapted to the environment inside a vertical shaft. Background Technology

[0002] Most coal mines in my country mainly use underground mining methods, but this method often faces complex geological conditions and harsh working environments, resulting in a high risk of accidents. As a key connection channel between underground resources and the surface production system, the deformation, spalling and cracking of vertical shafts have a serious impact on the safe production of coal mines and the smooth mining of resources, which in turn brings significant economic losses to the country and society.

[0003] Currently, the detection equipment carried by inspection robots, such as ordinary cameras, infrared cameras and cross-section scanners, generally have insufficient detection accuracy, which limits their ability to detect common problems such as well casing deformation, well wall spalling and surface cracks.

[0004] Although these devices are widely used, their detection accuracy is not high, making it difficult to effectively identify and address common problems such as wellbore deformation, wellbore spalling, and surface cracks.

[0005] Ground penetrating radar, as a detection device, has significant advantages in detecting well casings, and can clearly reveal defects in the well casing;

[0006] However, when facing ultra-deep vertical shafts, the complex environment inside the shaft and the presence of many obstacles may affect the detection effect of air-coupled ground-penetrating radar, resulting in a decrease in image quality and an inability to accurately assess the wall condition.

[0007] Therefore, in order to obtain accurate detection results, the detection device needs to change in real time according to the environmental conditions inside the well, avoid obstacles and detect them at close range to ensure that effective detection data is provided. Summary of the Invention

[0008] Therefore, this utility model was made in view of the above problems. The purpose of this utility model is to first measure the distance to the obstacle using a laser rangefinder, then the central control system receives the data and makes adjustments, controlling the motor to drive the electric push rod to rotate behind the launch plate carrying the ground-penetrating radar on the target, and then using the electric push rod to push the launch plate carrying the ground-penetrating radar a certain distance, thereby achieving a close-range detection mode to solve the above problems. This utility model achieves the above objective through the following technical solution:

[0009] A defect detection device adapted to the environment inside a vertical shaft includes: an octagonal platform, an upper plate, an extension plate, and a lower platform. The octagonal platform is fitted onto multiple sets of positioning steel wire ropes through a rope hole one. The upper plate is fitted onto the positioning steel wire ropes through a rope hole two. Multiple sets of laser rangefinders are installed under the octagonal platform. A battery is installed in a battery compartment.

Multiple sets of pads are provided in the central groove. Multiple sets of slides are provided on the octagonal platform, and a side track is opened at the bottom of each set of slides. Multiple sets of rope holes one are provided on the upper surface of the octagonal platform. Side plates are provided on both sides of the extension plate. A ground penetrating radar is provided at the top of one end of the extension plate. An electromagnet one is provided on the side of the extension plate. A rear arc plate is provided at the other end of the extension plate. An electromagnet two is provided on the rear arc plate. A motor is installed in the central groove. A central block is provided at the drive end of the motor. An arc-shaped block is provided on one side of the central block.

[0010] Preferably, the upper plate has a tension steel wire rope at the center of its upper end face, and the upper end face of the upper plate has multiple battery compartments and rope holes.

[0011] Preferably, the rear end of the arc-shaped block is provided with a rod, the bottom of the central block is provided with a rotating hole, and the side of the central block is provided with an electric pusher.

[0012] Preferably, the rod is installed inside the electric pusher, and the center block is mounted on the motor through a rotating hole.

[0013] Preferably, the protruding plate is installed inside the slide rail, the side plate is installed inside the side rail, and the electromagnet is energized to attract the arc-shaped block.

[0014] Preferably, the lower platform has a 3D laser scanner at its lower end, multiple sets of support rods at its lower end, a lower plate at the bottom of the support rods, and multiple sets of CCD cameras and light sources installed under the lower plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model utilizes a laser rangefinder to first measure the distance to the obstacle. Then, the central control system receives the data and makes adjustments, controlling the motor to drive the electric push rod to rotate behind the push plate carrying the ground-penetrating radar.

[0034] like Figure 6 As shown, the octagonal platform 10 has a central circular hole 11 at the center of its upper surface, a central groove 111 at the center of the central circular hole 11, multiple sets of pads 112 inside the central groove 111, multiple sets of slides 12 from the central groove 111 to the side of the octagonal platform 10, each set of slides 12 having two sets of side tracks 121, and multiple sets of rope holes 13 on the upper surface of the octagonal platform 10.

[0035] like Figure 7 As shown, the upper plate 20 has a lifting steel wire rope 21 at the center of the upper end face, and the upper end face of the upper plate 20 has multiple battery compartments 22 and rope holes 23.

[0036] like Figure 8 As shown, the protruding plate 30 has two sets of side plates 31. The front end of the protruding plate 30 has a ground penetrating radar 32. The side of the protruding plate 30 has two sets of electromagnets 33. The electromagnets 33 can be energized to attract the slide rail 12 to fix the protruding plate 30. The rear end of the protruding plate 30 has a rear arc plate 34. The rear arc plate 34 has an electromagnet 35. The electromagnet 35 can be energized to attract the arc block 36 and connect the arc block 36 to the protruding plate 30.

[0037] like Figure 9 As shown, the rear end of the arc-shaped block 36 has a rod portion 361;

[0038] like Figure 10As shown, the center block 37 has a rotating hole 371 at the bottom and an electric push part 372 on the side of the center block 37;

[0040] The basic principle of this utility model:

[0041] like Figure 1 , Figure 2 As shown, when the detection device receives the detection command, it pulls up the steel wire rope 21 to release the line, and then the octagonal platform 10 moves downward along the positioning steel wire rope 14 through the rope hole 13 and the rope hole 23 via the upper plate 20 to perform detection. At this time, the extension plates 30 are all retracted into the slide rail 12. Multiple sets of ground penetrating radars 32 cooperate to perform circular line detection. At the same time, the three-dimensional laser scanner 41, CCD camera 44, and light source 45 work synchronously to perform three-dimensional scanning and image acquisition detection.

[0042] like Figure 3 , Figure 4 As shown, the laser rangefinder 15 operates to detect the environment below the well shaft, determine the distance to obstacles in multiple directions, and then transmit the data to the central control system. The central control system controls the motor 38 to rotate, which in turn rotates the electric pusher 372, causing the arc block 36 to rotate to the rear arc plate 34 of a set of protruding plates 30. Then, electromagnet 1 33 is released, and electromagnet 2 35 is attracted. Then, the electric pusher 372 pushes the arc block 36, which in turn pushes the protruding plate 30 and the ground-penetrating radar 32 to move outward. Then, electromagnet 1 33 is attracted, and electromagnet 2 35 is released. Then, the electric pusher 372 retracts the arc block 36. Then, the motor 38 continues to rotate, repeating this process to adjust the position of all the protruding plates 30 in real time.

[0043] When the bottom of the well is reached, all the extended plates 30 are retracted, and then the steel wire rope 21 is pulled up to retract the line, causing the upper plate 20 to return upward. When the top of the well is reached, the movement stops.
