[0002] Coal mine rock burst refers to the damage to the coal seam roof due to uneven force on the coal seam roof during coal mining, which causes drastic changes in mine pressure and produces a destructive geological disaster. In order to prevent and control the occurrence of rock burst accidents, it is necessary to conduct rock burst detection and early warning in coal mines to ensure safety during construction.

[0019] The beneficial effects of the present invention are:

[0020] (1) The coal mine rock burst disaster prevention and control detection and early warning device and its early warning method described in the present invention facilitate the installation block to enter the specified position inside the borehole through the detection mechanism, so that the detection mechanism contacts the hole wall with the cooperation of the control mechanism to realize pressure monitoring and early warning work, that is: through the installation of the connecting block, it is convenient to connect the support frame, and through the installation of the electric roller, it is convenient to move the installation block in the hole. Under the pull of the connecting spring, the symmetrically distributed support frames are brought close to each other, so that the electric roller is closely attached to the hole wall, and the simultaneous use of multiple electric rollers can realize the early warning and early warning of the rock burst disaster. The step-by-step operation is beneficial to the movement control of the mounting block. The installation of the mounting seat is beneficial to the connection of the detector.

The installation of the reset spring allows the mounting seat to be stored smoothly without causing jamming.

[0021] (2) The coal mine rock burst disaster prevention and control detection and early warning device and its early warning method described in the present invention, through the cooperation of the transmission mechanism, the control mechanism drives the cleaning mechanism to work, so that when the installation block enters the borehole, the debris on the inner wall is cleaned, so that the detection mechanism can better perform the monitoring work, that is: through the installation of the rotating shaft, it is convenient to connect the turntable, and through the connection of the turntable, multiple brushes can be installed. Through the rotation of the rotating shaft, the brushes can be rotated, which is convenient for cleaning the debris in the hole and pushing them to the end, so that the monitoring effect is better. Through the installation of the fixed sleeve, the rotating sleeve is driven by the screw rod to rotate with the inside of the fixed sleeve, and the rotating sleeve drives the card block to slide with the bevel rack inside the fixed sleeve, so that the slider cannot be driven by the screw rod, and the screw rod drives the rotating shaft to rotate continuously, so as to realize the brush cleaning work. After the installation block reaches the specified position, the screw rod will rotate in the opposite direction, so that the rotating sleeve drives the card block to rotate in the opposite direction, the card block contacts the bevel gear ring, and the card block drives the fixed sleeve to rotate, so that the fixed sleeve drives the slider to move one end position, which is convenient for the detector to slide out for detection.

[0022] (3) The coal mine rock burst disaster prevention and control detection and early warning device and its early warning method described in the present invention facilitate the sealing of one end of the mounting block through the installation of a sealing mechanism, so that the detection mechanism will not be disturbed by external factors and affect the detection effect, that is: through the installation of the airbag, under the operation of the air pump, the air pump generates gas to enter the interior of the conduit, and through the cooperation of the rotary joint, the gas is introduced into the interior of the rotating shaft. The gas is introduced into the interior of the airbag through the rotating shaft, and the airbag expands and becomes larger, which is beneficial to the sealing of the inside of the hole and the protection of the mounting block, so that the monitoring effect is better. When the mounting block is taken out, the air pump is exhausted to shrink and reset the airbag, which is convenient for taking out the mounting block.

[0023] (4) The coal mine rock burst disaster prevention and control detection and early warning device and its early warning method described in the present invention are convenient for connecting the two mounting blocks through the cooperation of the connecting mechanism and the locking mechanism, so that the two mounting blocks can pull each other when entering and exiting, thereby reducing energy consumption. Through the detection of the detection mechanisms on both sides, the detection effect is better and more accurate, that is: through the opening of the slot, it is convenient for the card holder to be engaged and connected with the mounting block, and through the connection of the pull rope, the mounting block can pull the other mounting block to move, which plays a role in saving resources and storing energy. When the card holder is inserted into the slot, the latch is resisted and contracted, so that the card holder can be fully inserted into the slot. The latch is reset and popped out under the elastic force of the resisting spring, and the latch is engaged with the inside of the slot, so that the card holder and the mounting block are firmly and stably connected. By pressing the two symmetrical pressing blocks, the pressing blocks drive the latch to get rid of the elastic force of the resisting spring and contract, and the latch is separated from the slot, which is convenient for the card holder and the mounting block to be pulled out and disassembled.

The installation of the mounting seat 301 is facilitated to connect the detector 203. The cooperation of the slide groove 302 enables the mounting seat 301 to slide inside the mounting block 1. The control of the stepping motor 303 realizes that the lead screw 304 drives the slider 306 to move, and the slider 306 drives the three driving rods 305 to drive and control the three mounting seats 301. The mounting seat 301 drives the detector 203 to slide out and contact the hole wall for monitoring.

The installation of the reset spring 307 makes the mounting seat 301 smooth when stored and is not easy to cause jamming. The installation of the rotating shaft 403 is conducive to the connection of the turntable 402. Through the connection of the turntable 402, multiple brushes 401 can be installed. The rotation of the rotating shaft 403 realizes the rotation of the brush 401, which is conducive to cleaning the debris in the hole and pushing it to the end, so that the monitoring effect is better. The installation of the fixed sleeve 501 makes the rotating sleeve 503 rotate with the inside of the fixed sleeve 501 under the drive of the screw rod 304, and the rotating The sleeve 503 drives the block 504 to slide with the helical rack inside the fixed sleeve 501, so that the slider 306 cannot be driven by the screw rod 304, and the screw rod 304 drives the rotating shaft 403 to rotate continuously, so as to realize the cleaning work of the brush 401.

The block 504 drives the fixed sleeve 501 to rotate, so that the fixed sleeve 501 drives the slider 306 to move one end position, which is beneficial for the detector 203 to slide out for detection. Through the installation of the airbag 801, under the operation of the air pump 802, the air pump 802 generates gas to enter the inside of the conduit 804, and through the cooperation of the rotating joint 803, the gas is The gas is introduced into the interior of the rotating shaft 403, and the gas is introduced into the interior of the airbag 801 through the rotating shaft 403. The airbag 801 expands and becomes larger, which is beneficial to the sealing of the inside of the hole and the protection of the mounting block 1, so that the monitoring effect is better. When the mounting block 1 is taken out, the air pump 802 is exhausted to shrink and reset the airbag 801, which is convenient for taking out the mounting block 1. The opening of the slot 603 is conducive to the engagement and connection between the card holder 601 and the mounting block 1. Through the connection of the pull rope 602, the mounting block 1 can pull another mounting block 1 to move, which plays a role in saving resources and storing energy. When the card holder 601 is inserted into the slot 603, the bayonet 703 is resisted and retracted, so that the card holder 601 can be fully inserted into the slot 603. The bayonet 703 is reset and popped out under the elastic force of the resisting spring 704.The latch pin 703 is engaged with the inside of the latch slot 702, so that the connection between the holder 601 and the mounting block 1 is firm and stable.
