[0008] Preferably, a filter plate is fixedly connected to the inner wall of the ventilation chamber, and the outer wall of the filter plate is fixedly connected to the ventilation chamber by threads.

[0009] Preferably, the cleaning component includes a fixed plate fixedly connected to the side of the transparent airbag near the monitoring and early warning device, a plurality of cleaning brushes fixedly connected to the rear side of the fixed plate, and a sealing gasket fixedly connected to the rear side of the fixed plate, with the sealing gasket corresponding to the position of the filter plate.

[0010] Preferably, the support assembly includes a first sliding plate slidably connected to the side of the fixed frame away from the monitoring and early warning device, the bottom surface of the fixed frame being fixedly connected to the first sliding plate, a fixed curved plate being fixedly connected to the side of the first sliding plate away from the monitoring and early warning device, rotating plates being rotatably connected to the front and rear sides of the fixed curved plate via shafts, connecting plates being rotatably connected to the sides of the two rotating plates away from the fixed frame via shafts, and a rubber pad being connected to the bottom surface of the first sliding plate, the side of the rubber pad away from the monitoring and early warning device being rotatably connected to the fixed frame via shafts.

[0014] The positive and progressive effects of this application are as follows:

[0015] The mine geological disaster monitoring and early warning equipment provided in this embodiment of the invention has the following advantages:

[0016] 1. By setting up a buffer air cushion structure, the monitoring and early warning equipment can be closely attached to the mine wall through the buffer air cushion structure, which has a buffering capacity and prevents the probe from separating from the mine wall in the event of mine vibration. The structure of the support components makes it easy for workers to quickly assemble the equipment, thereby reducing the defects of drilling fixation.

[0017] 2. After the protective airbag is filled with gas, the gas enters the interior of the buffer air cushion through the vent tube, causing the buffer air cushion to inflate. The buffer air cushion has a certain degree of elasticity, so that when the rear wall of the buffer air cushion encounters an uneven mine wall, it deforms and adheres tightly to the mine wall, thus giving the buffer air cushion structure a cushioning and protective effect.

[0018] 3. Through the mutual cooperation between the structures, the vibration effect of the mine wall on the monitoring and early warning equipment is transmitted to the support structure, and then effective buffering and pressure reduction are carried out, thereby protecting the monitoring and early warning equipment. The bottom support and buffer structure are specially designed to absorb the vertical vibration of blasting, the settlement of the roadway floor, and the low-frequency vibration of the mine car passing by, protecting the equipment base and internal circuits, and avoiding solder joint fatigue and sensor zero drift.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the scope of protection of the present invention.

[0026] like Figures 1-5 As shown, the present invention is a monitoring and early warning device for geological disasters in mines, including a fixed frame 1, a support unit 2 fixedly connected to the inner side of the fixed frame 1, and a monitoring and early warning device 3 fixedly connected to the inner wall of the support unit 2.

[0027] The support unit 2 includes an inflatable component 25 that is slidably connected to the inner wall of the fixed frame 1. Protective airbags 22 are slidably connected to the outer walls of the left and right inflatable components 25. A cushioning airbag 23 is fixedly connected to the rear side of the protective airbag 22. A venting tube 24 is fixedly connected to the rear side of the protective airbag 22 and is inserted into the interior of the cushioning airbag 23. A support component 26 is fixedly connected to the outer wall of the fixed frame 1. A cleaning component 27 is slidably connected to the front side of the inflatable component 25. A transparent airbag 21 is fixedly connected to the inner top surface of the protective airbag 22.

[0028] Specifically, when this device is needed, it needs to be assembled. The combined structure of the protective airbag 22 and the buffer air cushion 23 needs to be fitted onto the outer wall of the monitoring and early warning device 3. Then, the combined structure of the protective airbag 22 and the inflation component 25 securely connects the inflation component 25 to the monitoring and early warning device 3. Next, the structure of the support component 26 is inserted into the interior of the fixed frame 1 to complete the connection. The bottom support component 26 is fixedly connected to the fixed frame 1 with screws. Then, the monitoring and early warning device 3 carrying the inflation component 25 is inserted into the inner wall of the fixed frame 1. During the insertion of the inflation component 25... The movement inflates the protective airbag 22. Once the airbag 22 is full, the gas is transferred to the cushioning air cushion 23 through the vent pipe 24. The rear wall of the cushioning air cushion 23 is in close contact with the mine wall. After the bottom structure of the support component 26 is fixedly connected to the mine ground, the rear wall of the cushioning air cushion 23 is in close contact with the mine wall. The support component 26 structure on the bottom of the fixed frame 1 provides support for tilting. The air cushion is a flexible, deformable, and pressure-holding medium. It is not in rigid contact with the mine wall. The rock wall is uneven, has bulges and cracks. The air cushion can adaptively fill, ensuring full coverage and preventing local suspension.

[0029] Preferably, the inflatable assembly 25 includes a retaining plate 252 fixedly connected to the outer wall of the support unit 2. A sliding frame 251 is slidably connected to the outer wall of the retaining plate 252. The sliding frame 251 has a cavity inside. A first connecting shaft 253 is rotatably connected to the inner wall of the sliding frame 251. A first gear 254 is fixedly connected to the outer wall of the first connecting shaft 253. A second connecting shaft 255 is rotatably connected to the inner wall of the sliding frame 251, and the second connecting shaft 255 is located on the side of the first connecting shaft 253 closer to the support unit 2. A second gear is fixedly connected to the outer wall of the second connecting shaft 255. Wheel 256, second gear 256 meshes with first gear 254, fan blade 259 is fixedly connected to the outer wall of second connecting shaft 255, fan blade 259 is located in front of second connecting shaft 255, ventilation chamber 2511 matching fan blade 259 is opened on the inner wall of sliding frame 251, air guide pipe 258 is fixedly connected to the rear side of ventilation chamber 2511, one end of air guide pipe 258 away from ventilation chamber 2511 is inserted into the interior of protective airbag 22, tooth grooves 257 matching first gear 254 are opened on the inner walls of both the left and right sides of fixed frame 1;

[0030] Specifically, when this component is needed, the combined structure of the protective airbag 22, the buffer air cushion 23, and the sliding frame 251 needs to be fixed to the monitoring and early warning device 3 via the clamping plate 252. After fixing, the structure of the monitoring and early warning device 3 is lifted and inserted into the inner wall of the fixed frame 1 from top to bottom. During the insertion of the sliding frame 251, the first gear 254 generates force with the tooth groove 257 under the action of the first connecting shaft 253, causing the first gear 254 to rotate. The first gear 254, through the meshing action with the second gear 256, rotates. The second gear 256 drives the second connecting shaft 255 to rotate, and the second connecting shaft 255 drives the fan blade 259 to rotate. The fan blade 259 generates negative pressure inside the ventilation chamber 2511. The negative pressure enters the interior of the protective airbag 22 through the air guide pipe 258. After the protective airbag 22 is filled with gas, the gas enters the interior of the buffer air cushion 23 through the air vent pipe 24, causing the buffer air cushion 23 to be inflated. The buffer air cushion 23 has a certain elasticity, so that when the rear wall of the buffer air cushion 23 encounters an uneven mine wall, it deforms and sticks tightly to the mine wall, so that the structure of the buffer air cushion 23 has a buffer protection effect.

[0031] Preferably, a filter plate 2510 is fixedly connected to the inner wall of the ventilation chamber 2511, and the outer wall of the filter plate 2510 is fixedly connected to the ventilation chamber 2511 by threads.

[0032] Specifically, the filter plate 2510 is used to filter the air inside the mine, preventing impurities from accumulating inside the ventilation chamber 2511 after the air filling component 25 structure is used. At the same time, the filter plate 2510 and the ventilation chamber 2511 are connected by threads, making the filter plate 2510 easy to disassemble and handle quickly.

[0033] Preferably, the cleaning component 27 includes a fixed plate 271 fixedly connected to the side of the transparent airbag 21 near the monitoring and early warning device 3, a plurality of cleaning brushes 273 fixedly connected to the rear side of the fixed plate 271, and a sealing gasket 272 fixedly connected to the rear side of the fixed plate 271, and the sealing gasket 272 corresponds to the position of the filter plate 2510.

[0034] Specifically, during the movement of the inflation component 25 within the fixed frame 1, the filter plate 2510 encounters multiple cleaning brushes 273 fixed by the fixed plate 271. The cleaning brushes 273 clean the surface of the filter plate 2510, causing most of the impurities attached to the front side of the filter plate 2510 to fall off and separate. Then, the filter plate 2510 moves to the area of ​​the sealing gasket 272, where the remaining impurities on the surface of the filter plate 2510 are cleaned by friction from the elastic rubber sealing gasket 272 and fall off and separate. At the same time, the sealing gasket 272 seals the ventilation chamber 2511, so that impurities will not enter the interior of the ventilation chamber 2511 during normal use after the equipment is assembled, thus keeping the internal structure clean.

[0035] Preferably, the support component 26 includes a first sliding plate 261 slidably connected to the side of the fixed frame 1 away from the monitoring and early warning device 3. The bottom surface of the fixed frame 1 is fixedly connected to the first sliding plate 261. A fixed curved plate 262 is fixedly connected to the side of the first sliding plate 261 away from the monitoring and early warning device 3. Rotating plates 263 are rotatably connected to the front and rear sides of the fixed curved plate 262 via shafts. A connecting plate 264 is rotatably connected to the side of the two rotating plates 263 away from the fixed frame 1 via shafts. A rubber pad 2612 is connected to the bottom surface of the first sliding plate 261. The side of the rubber pad 2612 away from the monitoring and early warning device 3 is rotatably connected to the fixed frame 1 via shafts.

[0036] Specifically, when a portion of the supporting component 26 needs to be used, the structure of the rotating plate 263 needs to be flipped via an axis, so that most of the area of ​​the rotating plate 263 is separated from the connecting plate 264. Then, when contacting the fixed curved plate 262, the structure of the rotating plate 263 is restored so that the fixed curved plate 262 is rotatably connected to the rotating plate 263 via an axis. Then, the first sliding plate 261 is connected. The fixed curved plate 262 is limited by the groove sidewall of the fixed frame 1 that accommodates the first sliding plate 261, thereby maintaining the relatively fixed connection between the rotating plate 263 and the connecting plate 264, so that the rotating plate 263 will not flip before disassembly. The mutual cooperation between the structures makes the operation of the structure simple and significantly improves the assembly and disassembly speed.

[0037] Preferably, the connecting plate 264 has a cavity inside, and a second sliding plate 265 is slidably connected inside the connecting plate 264. Multiple moving shafts 266 are fixedly connected to the top surface of the second sliding plate 265, and springs 267 are slidably sleeved on the outer wall of the moving shafts 266. A triangular bracket 268 is fixedly connected to the bottom surface of the second sliding plate 265, and a fixing rod 269 is fixedly connected to the bottom surface of the triangular bracket 268.

[0038] Specifically, when this device encounters external vibration during use, the vibration transmits power through the protective airbag 22 to the monitoring and early warning device 3. The monitoring and early warning device 3 then transmits the vibration to the fixed frame 1, which in turn transmits it to the connecting plate 264. Simultaneously, when the connecting plate 264 encounters vibration, the internal second sliding plate 265 moves, driving the moving shaft 266 to move. This movement of the second sliding plate 265 and the moving shaft 266 compresses the spring 267, thus buffering the vibration transmitted by the device and preventing damage to the monitoring and early warning device 3 from prolonged vibration. In addition to preventing structural vibration from causing equipment displacement, the second sliding plate 265 drives the moving shaft 266 to move and insert into the interior of the rotating plate 263, thereby assisting in fixing the rotating plate 263. Through the cooperation between the structures, the vibration effect of the mine wall on the monitoring and early warning equipment 3 is transmitted to the support structure, and then effectively buffered and depressurized, thereby protecting the monitoring and early warning equipment 3. The bottom support and buffer structure are specially designed to absorb the vertical vibration of blasting, the settlement of the roadway floor, and the low-frequency vibration of the mine car passing through, protecting the equipment base and internal circuits, and avoiding solder joint fatigue and sensor zero-point drift.

[0039] Ideally, the end of the fixing rod 269 away from the triangular bracket 268 is fixedly connected to the base plate 2611 via a universal joint, and multiple insertion rods 2610 are fixedly connected to the bottom surface of the base plate 2611.

[0040] Specifically, by setting a universal joint to connect the base plate 2611, when the base plate 2611 and the insertion rod 2610 are placed on the ground, the protruding part of the base plate 2611 can be directly stepped on with the foot, which facilitates the installation by the staff. At the same time, the universal structure allows the staff to adjust the installation angle of the fixing rod 269 according to the installation terrain, thereby maintaining the horizontal state of the monitoring and early warning equipment 3 after installation.

[0041] Preferably, a groove matching the first slide plate 261 is provided on the side of the fixed frame 1 away from the support unit 2, and a rubber pad 2612 is rotatably connected to the bottom of the groove via a shaft;

[0042] Specifically, when the first slide plate 261 is inserted into the groove of the fixed frame 1, it achieves high stability by being fully inserted into the fixed frame 1 from the top. At the same time, the first slide plate 261 has a groove on the side near the monitoring and early warning device 3 to connect with the sliding frame 251, thereby improving the fixing effect of the connection between the first slide plate 261 and the sliding frame 251, thus improving the usability of the first slide plate 261 structure. Then, by setting the structure of the rubber pad 2612, the first slide plate 261 is limited and supported after the connection is completed, thereby preventing the first slide plate 261 from separating from the fixed frame 1 during the placement process by the staff, thereby improving the tightness of the connection between the first slide plate 261 and the fixed frame 1.

[0043] The work process is as follows:

[0044] When this equipment is needed, it needs to be assembled. The combined structure of the protective airbag 22 and the buffer air cushion 23 needs to be fitted onto the outer wall of the monitoring and early warning equipment 3. Then, the combined structure of the protective airbag 22 and the inflation component 25 makes the inflation component 25 and the monitoring and early warning equipment 3 fixedly connected. Then, the structure of the support component 26 is inserted into the inside of the fixed frame 1 to complete the connection. The bottom support component 26 is fixedly connected to the fixed frame 1 by screws. Then, the monitoring and early warning equipment 3 carrying the inflation component 25 is inserted into the inner wall of the fixed frame 1. During the insertion of the inflation component 25, it moves to inflate the inside of the protective airbag 22. After the inside of the protective airbag 22 is full of gas, the gas is transmitted into the inside of the buffer air cushion 23 through the vent pipe 24. The rear wall of the buffer air cushion 23 is close to the mine wall. After the bottom structure of the support component 26 is fixedly connected to the mine ground, the rear wall of the buffer air cushion 23 is close to the mine wall.

[0045] The support component 26 on the bottom of the fixed frame 1 provides support for tilting. The air cushion is a flexible, deformable, and pressure-holding medium. It does not have a rigid contact with the mine wall. The rock wall is uneven, with bulges and cracks. The air cushion can self-fill to ensure full coverage and prevent local suspension. The protective airbag 22 protects the surface of the monitoring and early warning device 3 from falling impurities when the mine is vibrating, preventing the falling impurities from touching the monitoring and early warning device 3. The transparent airbag 21 protects the display part of the monitoring and early warning device 3 and also has a dustproof function. When the staff needs to operate the monitoring and early warning device 3, they only need to lift the transparent airbag 21 structure to operate it, making the operation more convenient. The buffer airbag 23 ensures that the monitoring and early warning device 3 is in close contact with the mine wall, providing a buffering capacity and preventing the probe from separating from the mine wall when the mine is vibrating. The support component 26 facilitates quick assembly of the equipment by the staff, thereby reducing the defects of drilling and fixing.

[0046] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
