A square groove is opened on the bottom of the disc. A moving rod is movably sleeved on one side of the inner cavity of the square groove. A spring is movably sleeved on the outer side of the moving rod. A clamping plate is fixedly installed on one end of the moving rod. The clamping plate and the disc are fixedly installed on both ends of the spring, respectively. The bottom of the air inlet channel is rotatably connected to a connecting shaft and a second gear by a bracket. A first bevel gear is fixedly installed on the bottom of the connecting shaft. The outer teeth of the first bevel gear and the second gear mesh with each other. The front side of the second gear is connected to the first rotating shaft by a belt drive assembly.
[0006] As a further improvement of the present invention, the belt drive assembly includes a first pulley and a first drive belt. The first pulley is fixedly sleeved on the front side of the first rotating shaft and the front side of the second gear, and the two first pulleys are connected by the first drive belt.
[0007] As a further improvement of the present invention, the bottom of the disk is provided with a plurality of square slots, a moving rod, a spring and a clamping plate, which are evenly distributed along the circumference of the disk.
[0008] As a further improvement of the present invention, when the inner side of the clamping plate is in contact with the first bevel gear, the spring is in a compressed state, and the inner side of the clamping plate is in frictional connection with the outer side of the connecting shaft.
[0009] As a further improvement of the present invention, the adsorbent regeneration assembly includes a discharge bin, a cylinder, a screw conveyor, a feed pipe, a third rotating shaft, and friction heating plates. The bottom of the gas monitoring and early warning instrument and the first adsorption box are both fixedly installed with discharge bins. The cylinder is connected to the rear side of the discharge bin. The screw conveyor is rotatably connected to the inner cavity of the cylinder. The feed pipe is fixedly sleeved on the upper part of the cylinder. The bottom of the first bevel gear is fixedly installed with a third rotating shaft. The third rotating shaft and the bottom of the screw conveyor are connected by a belt drive assembly. Friction heating plates are provided on the outer side of the screw conveyor.
[0010] As a further improvement of the present invention, the bottom of the inner cavity of the discharge bin is inclined, and the bottom of the cylinder is lower than the bottom of the discharge bin.
[0011] As a further improvement of the present invention, the feed pipe is inclined in shape, and the top of both the first adsorption box and the second adsorption box is provided with a feed pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are: Rotating blades are located on the sides of the first and second adsorption boxes. When the first and second adsorption boxes are normally air-intaken, the rotating blades rotate rapidly, thereby driving the second rotating shaft to rotate. Since the bottom of the second rotating shaft is equipped with a disc, and the bottom of the disc is equipped with a moving rod, spring, and clamping plate, the clamping plate moves outward under the influence of centrifugal force, releasing the restriction on the connecting shaft. Therefore, the second rotating shaft will not drive the connecting shaft to rotate, and thus will not drive the first rotating shaft and the discharge blades to rotate. When the first and second adsorption boxes absorb a certain amount of moisture and carbon dioxide, the rotating blades on the sides of the first and second adsorption boxes can come into contact with a small amount of airflow. At this time, the rotation of the second rotating shaft drives the connecting shaft and the first bevel gear to rotate using the clamping plate. The second gear and belt drive assembly drive the first rotating shaft and the discharge blades to rotate, which facilitates the discharge of the used moisture absorbent and carbon dioxide absorbent. The new moisture absorbent and carbon dioxide absorbent located above the first and second adsorption boxes are moved into the air inlet channel for use, thus not affecting the continuous use of this device. The rotation of the connecting shaft drives the screw conveyor to rotate, and the adsorbent discharged by the rotating discharge blades enters the cylinder through the discharge bin. Since the outside of the screw conveyor is equipped with friction heating plates, a certain amount of heat is generated when the screw conveyor rotates, which heats the adsorbent in the cylinder, making it easier to recycle. The dried adsorbent enters the first adsorption box and the second adsorption box again through the feed pipe, so that the moisture absorbent and carbon dioxide absorbent in the first adsorption box and the second adsorption box can be reused.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-8This invention provides a deep mining rockburst and gas coupling monitoring and early warning device, including a monitoring box 1. An air inlet channel 2 is fixedly installed in the inner cavity of the monitoring box 1. A fan 3 is fixedly installed on one side of the air inlet channel 2. A gas monitoring and early warning instrument 4 is installed on one side of the fan 3. A first adsorption box 5 and a second adsorption box 6 are fixedly sleeved in the middle of the air inlet channel 2. The inner cavities of the first adsorption box 5 and the second adsorption box 6 respectively store a moisture absorbent and a carbon dioxide absorbent. Both the first adsorption box 5 and the second adsorption box 6 are provided with an adsorbent replacement component 7 and an adsorbent regeneration component 8. The adsorbent regeneration component 8 is located on the rear side of the adsorbent replacement component 7. A rockburst monitoring and early warning instrument 9 is provided on the top of the inner cavity of the monitoring box 1.
[0019] The gas monitoring and early warning device 4 consists of four parts: a power supply unit (directly reusing the mine lamp battery, eliminating the need for an additional power module), a detection unit (using a QM-N5 gas sensor with an adjustable sliding resistor RP to acquire concentration signals), a control unit (building a delay trigger circuit based on a VT1 transistor, providing 30 seconds of anti-interference and noise reduction), and an alarm unit (equipped with an HFC221A voice chip, pre-stored with the digital audio message "Gas exceeding limits, danger! Evacuate immediately!"). When the underground gas concentration exceeds the safe threshold of 0.5%vol, the impedance change of the gas sensor causes a shift in the resistance value of RP. The voltage signal is then delayed by a circuit to eliminate instantaneous disturbances, triggering the voice chip's operating circuit, and the speaker continuously broadcasts an alarm until the concentration returns to normal.
[0020] The rockburst monitoring and early warning instrument 9 monitors the changes in the stress field ahead of the working face in real time, identifies high-stress areas and their changing trends, and achieves real-time monitoring, early warning, and forecasting of rockburst hazard areas and their severity. As a further improvement of the present invention, the adsorbent replacement assembly 7 includes a first rotating shaft 701 and a second rotating shaft 703. The lower part of the inner cavity of the first adsorption box 5 and the second adsorption box 6 are rotatably connected to the first rotating shaft 701. A discharge blade 702 is fixedly installed on the outer side of the first rotating shaft 701. The bottom of the air inlet channel 2 is rotatably connected to the second rotating shaft 703 located on one side of the first adsorption box 5 and the second adsorption box 6. A rotating blade 704 is fixedly installed on the upper part of the second rotating shaft 703. A disc 705 is fixedly installed on the bottom of the second rotating shaft 703. A square groove 706 is formed at the bottom of the disc 705. A movable rod 707 is movably sleeved on one side of the inner cavity, and a spring 708 is movably sleeved on the outside of the movable rod 707. A clamping plate 709 is fixedly installed at one end of the movable rod 707, and the clamping plate 709 and the disc 705 are fixedly installed at both ends of the spring 708, respectively. A connecting shaft 710 and a second gear 712 are rotatably connected to the bottom of the air inlet channel 2 by means of a bracket. A first bevel gear 711 is fixedly installed at the bottom of the connecting shaft 710. The external teeth of the first bevel gear 711 and the second gear 712 mesh with each other. The front side of the second gear 712 is connected to the first rotating shaft 701 by a belt drive assembly.
[0021] Rotating blades 704 are provided on the sides of the first adsorption box 5 and the second adsorption box 6. When the first adsorption box 5 and the second adsorption box 6 are normally air-intake, the rotating blades 704 are driven to rotate rapidly, thereby driving the second rotating shaft 703 to rotate. Since the bottom of the second rotating shaft 703 is provided with a disc 705, and the bottom of the disc 705 is provided with a moving rod 707, a spring 708 and a clamping plate 709, the clamping plate 709 moves outward under the influence of centrifugal force, releasing the restriction on the connecting shaft 710. Therefore, when the second rotating shaft 703 rotates, it will not drive the connecting shaft 710 to rotate, and thus will not drive the first rotating shaft 701 and the discharge blades 702 to rotate. When the second adsorption box 6 absorbs a certain amount of moisture and carbon dioxide, the rotating blades 704 on the sides of the first adsorption box 5 and the second adsorption box 6 can come into contact with a small amount of airflow. At this time, the second rotating shaft 703 rotates, which drives the connecting shaft 710 and the first bevel gear 711 to rotate via the clamping plate 709. The second gear 712 and the belt drive assembly drive the first rotating shaft 701 and the discharge blades 702 to rotate, which facilitates the discharge of the used moisture absorbent and carbon dioxide absorbent. The new moisture absorbent and carbon dioxide absorbent located above the first adsorption box 5 and the second adsorption box 6 are moved into the air inlet channel 2 for use, so as not to affect the continuous use of this device.
[0022] As a further improvement of the present invention, the belt drive assembly includes a first pulley 713 and a first drive belt 714. The first pulley 713 is fixedly sleeved on the front side of the first rotating shaft 701 and the front side of the second gear 712, and the two first pulleys 713 and the first drive belt 714 are connected in a drive connection.
[0023] The first gear 712 and the first shaft 701 are connected by the first pulley 713 and the first transmission belt 714. This allows the discharge blades 702 on the first shaft 701 to rotate when the second shaft 703 drives the first bevel gear 711 to rotate slowly. This discharges the moisture absorbent and carbon dioxide absorbent in the gas monitoring and early warning instrument 4 and the first adsorption box 5, and allows the moisture absorbent and carbon dioxide absorbent located above the first adsorption box 5 and the second adsorption box 6 to enter the air inlet channel 2 for use.
[0024] As a further improvement of the present invention, the bottom of the disk 705 is provided with a plurality of square grooves 706, a moving rod 707, a spring 708 and a clamping plate 709, and the plurality of square grooves 706, the moving rod 707, the spring 708 and the clamping plate 709 are evenly distributed along the circumference of the disk 705.
[0025] By incorporating several square slots 706, a moving rod 707, a spring 708, and a clamping plate 709, the stability of the linkage between the disc 705 and the connecting shaft 710 is improved.
[0026] As a further improvement of the present invention, when the inner side of the clamping plate 709 is in contact with the first bevel gear 711, the spring 708 is in a compressed state, and the inner side of the clamping plate 709 is in frictional connection with the outer side of the connecting shaft 710.
[0027] By frictionally connecting the inner side of the clamping plate 709 with the outer side of the connecting shaft 710, the clamping plate 709 below the disk 705 will not generate centrifugal force when the second rotating shaft 703 rotates slowly, thus preventing the clamping plate 709 from separating from the connecting shaft 710, thereby driving the connecting shaft 710 to rotate, which in turn drives the first rotating shaft 701 to rotate.
[0028] Example 2 Please see Figures 4-7 The adsorbent regeneration assembly 8 includes a discharge bin 801, a cylinder 802, a screw conveyor 803, a feed pipe 804, a third rotating shaft 805, and friction heating plates 808. The bottom of the gas monitoring and early warning instrument 4 and the first adsorption box 5 are both fixedly installed with the discharge bin 801. The cylinder 802 is connected to the rear side of the discharge bin 801. The screw conveyor 803 is rotatably connected to the inner cavity of the cylinder 802. The feed pipe 804 is fixedly sleeved on the upper part of the cylinder 802. The bottom of the first bevel gear 711 is fixedly installed with the third rotating shaft 805. The third rotating shaft 805 and the bottom of the screw conveyor 803 are connected by a belt drive assembly. Friction heating plates 808 are provided on the outer side of the screw conveyor 803.
[0029] The rotation of the connecting shaft 710 drives the screw conveyor 803 to rotate, and the adsorbent discharged by the discharge blades 702 enters the cylinder 802 through the discharge bin 801. Since the screw conveyor 803 is equipped with friction heating plates 808 on the outside, a certain amount of heat is generated when the screw conveyor 803 rotates, which heats the adsorbent in the cylinder 802, making it easier to recycle. The dried adsorbent enters the first adsorption box 5 and the second adsorption box 6 again through the feed pipe 804, so that the moisture absorbent and carbon dioxide absorbent in the first adsorption box 5 and the second adsorption box 6 can be reused.
[0030] As a further improvement of the present invention, the bottom of the inner cavity of the discharge bin 801 is inclined, and the bottom of the cylinder 802 is lower than the bottom of the discharge bin 801. Due to the shape characteristics of the bottom of the discharge bin 801, the adsorbent is facilitated to slide down under the influence of gravity and enter the cylinder 802 for conveying.
[0031] As a further improvement of the present invention, the feed pipe 804 is inclined in shape, and the top of both the first adsorption box 5 and the second adsorption box 6 are provided with the feed pipe 804. Due to the shape characteristics of the feed pipe 804, it is convenient to let the dried adsorbent in the cylinder 802 re-enter the first adsorption box 5 and the second adsorption box 6 through the feed pipe 804, so as to facilitate recycling.
[0032] Working principle: When using this device, the monitoring box 1 is installed in the mine, so that the rockburst monitoring and early warning instrument 9 is in contact with the mine wall. The rockburst monitoring and early warning instrument 9 is based on the principle of "equivalent drill cuttings method" and "multi-factor coupled rockburst hazard determination method". It achieves accurate and continuous monitoring and real-time early warning by monitoring the relative stress value of the coal body. The blower 3 and the gas monitoring and early warning instrument 4 are started. The blower 3 uses the air intake channel 2 to draw air from the bottom of the air intake channel 2 into the gas monitoring and early warning instrument 4 for monitoring. When the underground gas concentration exceeds the safety threshold of 0.5%vol, the impedance change of the gas-sensitive device causes the RP resistance value to shift, and the speaker continuously broadcasts the warning until the concentration returns to normal. When the gas passes through the first adsorption box 5 and the second adsorption box 6 in the air inlet channel 2, under normal use conditions of the moisture absorbent and carbon dioxide absorbent in the first adsorption box 5 and the second adsorption box 6, the gas flow rate is relatively fast, which drives the rotating blades 704 on the side of the first adsorption box 5 and the second adsorption box 6 to rotate rapidly, thereby driving the disc 705 at the bottom of the second rotating shaft 703 to rotate rapidly. Since the clamping plate 709 is connected to the disc 705 by the spring 708 and the moving rod 707, when the disc 705 rotates rapidly, centrifugal force is generated, which causes the clamping plate 709 to move outward and compress the spring 708, so that the disc 705 is not connected to the connecting shaft 710, and thus will not drive the connecting shaft 710 to rotate. After a period of use, the moisture absorbent and carbon dioxide absorbent in the first adsorption box 5 and the second adsorption box 6 adsorb a large amount of moisture and carbon dioxide. This causes blockage when the gas passes through the first adsorption box 5 and the second adsorption box 6, reducing the amount of gas that can pass through them. The small amount of gas can only drive the rotating blade 704 to rotate slowly, thereby driving the disc 705 to rotate slowly. This eliminates the centrifugal force on the clamping plate 709. Utilizing the frictional connection between the clamping plate 709 and the connecting shaft 710 and the elastic force of the spring 708, the disc 705 is driven by the clamping plate 709 to slowly rotate the connecting shaft 710. The first bevel gear 711 and the second gear 712 are meshed together via the connecting shaft 710, thereby driving the second gear 712 to rotate. Since the second gear 712 is connected to the first rotating shaft 701 via the first pulley 713 and the first transmission belt 714, the first rotating shaft 701 and the discharge blades 702 rotate slowly. Through the rotation of the discharge blades 702, the moisture absorbent and carbon dioxide absorbent in the first adsorption box 5 and the second adsorption box 6 are discharged from the bottom into the discharge hopper 801. At this time, the moisture absorbent and carbon dioxide absorbent above the first adsorption box 5 and the second adsorption box 6 enter the air intake. The material is used in channel 2. Utilizing the inclined bottom of the discharge bin 801, the used moisture absorbent and carbon dioxide absorbent in the discharge bin 801 slide downwards under gravity into the cylinder 802. The rotation of the connecting shaft 710 and the first bevel gear 711 drives the third rotating shaft 805 to rotate. The second pulley 806 and the second transmission belt 807 then drive the screw conveyor 803 to rotate. The rotation of the screw conveyor 803 transports the used moisture absorbent and carbon dioxide absorbent towards the upper part of the cylinder 802. Because the screw conveyor 803 is equipped with friction heating plates 808 on its outer side, the material... When machine 803 rotates, friction generates heat, which dries the used moisture absorbent and carbon dioxide absorbent. After being conveyed by screw conveyor 803, the dried moisture absorbent and carbon dioxide absorbent re-enter the first adsorption box 5 and the second adsorption box 6 through feed pipe 804 for reuse. When the first adsorption box 5 and the second adsorption box 6 are replaced with new moisture absorbent and carbon dioxide absorbent, the first adsorption box 5 and the second adsorption box 6 are allowed to ventilate normally. At this time, rotating blade 704 rotates rapidly, thereby stopping the rotation of discharge blade 702 and screw conveyor 803, and stopping the replacement of moisture absorbent and carbon dioxide absorbent.
