Description

Technical Field

[0001] The present invention relates to the technical field of borehole television imagers, and specifically, to a device for detecting the height of the water-conducting fissure zone in thick coal seams. Background Art

[0002] After coal seam mining, the surrounding rock of the stope deforms and fails, resulting in fissures. And the mining-induced fissures are the root cause of a series of coal mine disasters. Therefore, determining the height of the water-conducting fissure zone in the working face can not only ensure the production safety of coal mining under water bodies, but also play an important role in mastering the movement and failure laws of overlying strata during the mining of coal seam groups. In addition, it is also of great significance for improving the recovery of coal pillars and reducing coal losses. The height of the water-conducting fissure zone formed after thick coal seam mining is a key parameter for preventing and controlling mine water disasters, and its detection devices and methods need to be selected in combination with geological conditions, mining technology and technical requirements. The following are the commonly used detection devices and technical solutions: 1. Borehole television imager (borehole peephole instrument); 2. Microseismic monitoring system; 3. Distributed optical fiber sensing system (DTS / BOTDR); 4. Hydrogeological observation borehole and injection test; 5. Seismic wave / electromagnetic wave CT imaging, etc.

[0003] Among them, the borehole television imager (borehole peephole instrument) mainly consists of a ground part and an underground part. The ground part includes a controller, a computer, a tripod, a winch, a pulley and a depth counter, and the underground part includes a camera probe and a cable. The camera probe is composed of a CCD camera, an LED lamp, a glass cover and a conical mirror. When conducting detection work, the probe is lowered into the hole to detect the hole wall environment, and the detection results are analyzed and processed by a computer.

[0004] However, in the actual use process of the existing borehole television imager, there are relatively large limitations. When the borehole diameter is too large, using the borehole television imager (borehole peephole instrument) for fissure detection will face the following challenges:

[0005] The distance between the camera and the hole wall is too far, resulting in a decrease in image resolution and making it difficult to clearly identify the details of the fissures;

[0006] Insufficient light, the reflected light from the hole wall is weakened, affecting the imaging effect;

[0007] The stability of the camera is poor and it is easy to shake, resulting in blurred images;

[0008] Manual wire laying control is required, and the degree of automation is low.

[0009] In view of these problems, the present invention proposes a device for detecting the height of the water-conducting fissure zone in thick coal seams to ensure the accuracy and reliability of fissure detection. Summary of the Invention

Specific embodiments

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, a detecting device for the height of water-conducting fissure zone in thick coal seams, comprising: a probe 9, a towing line 4 connected to the top end of the probe 9, a rope reel 2 for taking in and paying out the probe 9, and a guiding frame 3 arranged between the rope reel 2 and the probe 9 for guiding and constraining the towing line 4. A guiding component 6 is arranged on one side of the guiding frame 3. The guiding component 6 includes a column 62 and a vertical frame 61. A threading groove 67 through which the towing line 4 can shuttle is formed through the center of the column 62. Two guiding rods 64 are symmetrically and fixedly connected to the top of the vertical frame 61. A right-angle block 65 is fixedly connected between the column 62 and the vertical frame 61. A supporting block 63 for supporting the guiding rods 64 is fixedly connected to the outer wall of the column 62. An installation platform 1 is arranged below the rope reel 2 for placing the rope reel 2. The guiding frame 3 includes a bracket 31 fixedly connected between the installation platform 1 and the vertical frame 61. A plurality of guiding pulleys 32 for constraining the towing line 4 are rotatably connected to the outer wall of the bracket 31.

[0040] A suspension mechanism 8 is arranged below the guiding component 6. The suspension mechanism 8 includes a wire bundler 81 for adjusting the sagging position of the towing line 4. A disc 84 is arranged above the wire bundler 81. A support column 82 for supporting the disc 84 is arranged between the disc 84 and the wire bundler 81. A plurality of constraint components 83 for suspending the probe 9 are annularly and arrayedly distributed at the bottom of the disc 84.

[0041] Among them, the wire bundler 81 includes a first L-shaped wire tube 811 fixedly connected to the bottom of the small bevel gear 734. The towing line 4 penetrates through the inside of the small bevel gear 734 and extends into the inside of the first L-shaped wire tube 811. A first outlet 812 through which the towing line 4 can pass out is formed at the corner of the first L-shaped wire tube 811. The wire bundler 81 further includes a second L-shaped wire tube 814. The support column 82 is fixedly connected to the outer wall of the second L-shaped wire tube 814. A second outlet 815 is formed at the bottom end of the second L-shaped wire tube 814. A connecting sleeve 813 is sleeved between the second L-shaped wire tube 814 and the first L-shaped wire tube 811. The first L-shaped wire tube 811 and the second L-shaped wire tube 814 are detachably and fixedly connected to the connecting sleeve 813 through bolts.

[0042] Furthermore, the constraint component 83 includes two fixing plates 831 fixedly connected to the bottom of the disc 84. A winding roller 833 is rotatably connected between the two fixing plates 831. A suspension wire 834 is wound around the inner side of the winding roller 833. The bottom end of the suspension wire 834 is connected to the upper side of the probe 9. A fixing cover 832 is fixedly connected to one side of the fixing plate 831. A rotating shaft 835 is rotatably connected inside the fixing cover 832. The rotating shaft 835 rotatably penetrates through the fixing plate 831 and is coaxially fixed to the winding roller 833. A torsion spring 836 is connected between the rotating shaft 835 and the fixing cover 832.

[0043] In this embodiment, during operation, when the diameter of the borehole to be detected is appropriate, the towing wire 4 can extend through the first outlet 812 opened at the corner of the first L-shaped wire tube 811, so that the probe 9 is on the center line of the borehole, ensuring that the probe 9 suspended by the towing wire 4 is always at the center position of the borehole. Herein, the towing wire 4 and the probe 9 can be detachably connected through a wire connector, which is a conventional wire connection method and will not be elaborated here. When the diameter of the borehole to be detected is relatively large, to ensure that the inner side of the borehole can be comprehensively detected by the probe 9, the distance between the second L-shaped wire tube 814 and the first L-shaped wire tube 811 is adjusted, enabling the towing wire 4 to pass through the second outlet 815, and the second L-shaped wire tube 814 and the first L-shaped wire tube 811 are fixed through the connecting sleeve 813, which can adjust the revolution range of the probe 9 suspended at the bottom of the towing wire 4, allowing the probe 9 to detect along the vicinity of the hole wall in the detection borehole.

[0044] In this embodiment, when it is necessary to detect the inner wall of the borehole by revolving the probe 9, when the probe 9 is lowered through the towing wire 4, the probe 9 pulls down the suspension wire 834, causing the wire winding roller 833 to drive the rotating shaft 835 to rotate and tighten the coil spring 836. Through the suspension of several suspension wires 834, the shaking of the probe 9 during lowering can be effectively reduced, improving the stability during operation. When the probe 9 moves upward, the downward pull on the suspension wire 834 is removed, and under the action of the coil spring 836, the suspension wire 834 can be automatically wound up.

[0045] Embodiment 2

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7 , a device for detecting the height of the water-conducting fissure zone in a thick coal seam, including all the contents of Embodiment 1. In addition, a wire clamping assembly 5 is provided on one side of the vertical frame 61 for clamping or releasing the towing wire 4.

[0047] A driving mechanism 7 is provided on one side of the vertical frame 61. The driving mechanism 7 includes a lifting block 71 slidably sleeved on the outer walls of two guide rods 64, a motor 72 fixedly installed on the outer wall of the column 62, and a transmission component 73 disposed between the motor 72 and the lifting block 71. During the process of driving the transmission component 73 by the motor 72, the suspension mechanism 8 can be revolved, and the lifting block 71 can be driven to move up and down reciprocally through the transmission component 73, thereby driving the wire clamping assembly 5.

[0048] Among them, the transmission component 73 includes a connecting shaft 731 fixedly connected to the outer wall of the lifting block 71 and a bevel gear 733 fixedly connected to one end of the output shaft of the motor 72. A fixing block 732 is fixedly connected to the outer wall of the bevel gear 733, and a connecting rod 735 is hinged between the fixing block 732 and the connecting shaft 731. The transmission component 73 further includes a small bevel gear 734 rotatably connected to the bottom of the column 62. The small bevel gear 734 is intermittently engaged with the bevel gear 733 during its rotation, and the traction wire 4 slidably penetrates through the inside of the small bevel gear 734.

[0049] Furthermore, the wire clamping assembly 5 includes a connecting plate 51 fixedly connected to the outer wall of the lifting block 71. One end of the connecting plate 51 is fixedly connected to a first clamping plate 52. A second clamping plate 54 is arranged on one side of the first clamping plate 52. A connecting rod 53 is hinged between the second clamping plate 54 and the first clamping plate 52. The traction wire 4 is located between the second clamping plate 54 and the first clamping plate 52. The wire clamping assembly 5 further includes a right-angle plate 55 fixedly connected to the side wall of the second clamping plate 54. A slideway 66 is opened inside the vertical frame 61. A sliding frame 56 is slidably sleeved inside the slideway 66. The right-angle plate 55 extends into the inside of the sliding frame 56. Ball bearings 57 are rotatably sleeved at both the upper and lower ends of the right-angle plate 55 inside the sliding frame 56. Ball grooves 58 for the ball bearings 57 to roll are opened on the inner walls of the upper and lower ends of the sliding frame 56.

[0050] In this embodiment, during the detection work, the motor 72 is started. The motor 72 slowly drives the bevel gear 733 to rotate through its output shaft. The bevel gear 733 drives the fixing block 732 to rotate. Every time the fixing block 732 rotates one week, it can drive the small bevel gear 734 to engage and rotate once, and every time the fixing block 732 rotates one week, it can drive the small bevel gear 734 to rotate one circle. Thereby, the small bevel gear 734 drives the first L-shaped wire pipe 811 to rotate one circle, and the traction wire 4 makes the probe 9 suspended at its bottom revolve one circle.

[0051] In this embodiment, when the small bevel gear 734 drives the fixed block 732 to revolve upward, the connecting rod 735 pushes up the lifting block 71 through the connecting shaft 731. During the process before the fixed block 732 revolves to the highest point, the half bevel gear 733 meshes with the small bevel gear 734 all the time. The half bevel gear 733 drives the small bevel gear 734 to rotate one week, so that the probe 9 suspended at the bottom of the traction wire 4 can detect along the hole wall in the detection hole. Moreover, during this process, when the lifting block 71 moves upward, it drives the first clamping plate 52 to move upward through the connecting plate 51. When the first clamping plate 52 moves upward, it pushes the second clamping plate 54 through the connecting rod 53, so that the right-angle plate 55 slides inside the sliding frame 56. With the assistance of the balls 57 and the ball grooves 58, the right-angle plate 55 can easily maintain horizontal sliding, so that the second clamping plate 54 moves away from the first clamping plate 52, thus the clamping on the traction wire 4 can be removed. As the lifting block 71 continues to move upward, the right end of the right-angle plate 55 first touches the inner wall of the sliding frame 56, so that the positions of the first clamping plate 52 and the second clamping plate 54 are relatively fixed. Then, the upward thrust of the lifting block 71 overcomes the friction between the sliding frame 56 and the slideway 66, driving the sliding frame 56 to slide upward inside the slideway 66, so that the traction wire 4 will not be pulled upward during the upward movement of the lifting block 71.

[0052] In this embodiment, when the fixed block 732 reaches the highest point and starts to revolve downward, at this time, the half bevel gear 733 does not mesh with the small bevel gear 734, so it will not drive the probe 9 to revolve. During this process, the lifting block 71 drives the first clamping plate 52 to move downward through the connecting plate 51. The first clamping plate 52 drags the second clamping plate 54 through the connecting rod 53, so that the right-angle plate 55 moves leftward inside the sliding frame 56, enabling the second clamping plate 54 and the first clamping plate 52 to clamp the traction wire 4. As the lifting block 71 continues to move downward, it overcomes the friction between the sliding frame 56 and the slideway 66, driving the sliding frame 56 to slide downward inside the slideway 66. Under the clamping of the second clamping plate 54 and the first clamping plate 52, the traction wire 4 can be pulled downward, so that the probe 9 at the bottom end of the traction wire 4 can move downward by a certain distance. Then, with the revolution of the probe 9, the internal environment of the next section of the hole can be detected.

[0053] Working principle and usage process: When working, when the diameter of the drilling hole to be detected is appropriate, the traction wire 4 can extend through the first outlet 812 opened at the corner of the first L-shaped wire tube 811, so that the probe 9 is on the center line of the drilling hole. At this time, during the rotation of the small bevel gear 734, the probe 9 suspended by the traction wire 4 can always be in the center position of the drilling hole. When the diameter of the drilling hole to be detected is relatively large, in order to ensure that the inner side of the drilling hole can be comprehensively detected by the probe 9, the distance between the second L-shaped wire tube 814 and the first L-shaped wire tube 811 is adjusted, so that the traction wire 4 passes through the second outlet 815 and the second L-shaped wire tube 814 and the first L-shaped wire tube 811 are fixed by the connecting sleeve 813. Thus, during the rotation of the small bevel gear 734, the revolution range of the probe 9 suspended at the bottom of the traction wire 4 can be adjusted, so that the probe 9 can detect along the hole wall in the detection hole.

[0054] During the detection work, the motor 72 is started. The motor 72 slowly drives the half bevel gear 733 to rotate through its output shaft. The half bevel gear 733 drives the fixed block 732 to rotate. Every time the fixed block 732 rotates one week, it can drive the small bevel gear 734 to engage and transmit once, and every time the fixed block 732 rotates one week, it can drive the small bevel gear 734 to rotate one circle. Thus, the small bevel gear 734 drives the first L-shaped wire tube 811 to rotate one circle, and the traction wire 4 makes the probe 9 suspended at its bottom revolve one circle.

[0055] Specifically, when the small bevel gear 734 drives the fixed block 732 to revolve upward, the connecting rod 735 pushes the lifting block 71 upward through the connecting shaft 731. During the process before the fixed block 732 revolves to the highest point, the half bevel gear 733 meshes with the small bevel gear 734 all the time. The half bevel gear 733 drives the small bevel gear 734 to rotate one week, so that the probe 9 suspended at the bottom of the traction wire 4 can detect along the hole wall in the detection hole. And, during this process, when the lifting block 71 moves upward, it will drive the first clamping plate 52 to move upward through the connecting plate 51. When the first clamping plate 52 moves upward, it pushes the second clamping plate 54 through the connecting rod 53, so that the right-angle plate 55 slides inside the sliding frame 56. With the assistance of the balls 57 and the ball grooves 58, the right-angle plate 55 can easily maintain a horizontal slide, so that the second clamping plate 54 moves away from the first clamping plate 52, thus the clamping on the traction wire 4 can be removed. As the lifting block 71 continues to move upward, the right end of the right-angle plate 55 first touches the inner wall of the sliding frame 56, so that the positions of the first clamping plate 52 and the second clamping plate 54 are relatively fixed. Then, the upward thrust of the lifting block 71 overcomes the friction between the sliding frame 56 and the slideway 66, driving the sliding frame 56 to slide upward inside the slideway 66, so that the lifting block 71 will not upwardly pull the traction wire 4 during the upward movement.

[0056] When the fixed block 732 reaches the highest point and starts to revolve downward, at this time, the bevel gear 733 is not engaged with the pinion 734, so it will not drive the probe 9 to revolve. During this process, the lifting block 71 drives the first clamping plate 52 to move downward through the connecting plate 51. The first clamping plate 52 drags the second clamping plate 54 through the connecting rod 53, causing the right-angle plate 55 to move leftward inside the sliding frame 56, so that the second clamping plate 54 and the first clamping plate 52 can clamp the traction wire 4. As the lifting block 71 continues to move downward, overcoming the friction between the sliding frame 56 and the slideway 66, it drives the sliding frame 56 to slide downward inside the slideway 66. Under the clamping of the second clamping plate 54 and the first clamping plate 52, the traction wire 4 can be pulled down, so that the probe 9 at the bottom end of the traction wire 4 can move downward by a certain distance. Then, as the probe 9 revolves, the internal environment of the next section of the hole can be detected.

[0057] When it is necessary to detect the inner wall of the drill hole by revolving the probe 9, when the probe 9 is lowered through the traction wire 4, the probe 9 pulls down the suspension wire 834, causing the wire winding roller 833 to drive the rotating shaft 835 to rotate and tighten the coil spring 836. Through the suspension of several suspension wires 834, the shaking of the probe 9 when it is lowered can be effectively reduced, and the stability during work can be improved. When the probe 9 moves upward, the downward pull on the suspension wire 834 is removed, and under the action of the coil spring 836, the suspension wire 834 can be automatically wound up.
