There are two first connecting rods 4 and two second connecting rods 5, and the two first connecting rods 4 and the two second connecting rods 5 form a quadrilateral structure, and the two first connecting rods 4 and the two second connecting rods 5 are distributed in parallel.

[0030] The first connecting rod 4 and the second connecting rod 5 form a quadrilateral structure, and the end away from the mounting seat 3 is rotatably connected to the support plate 6, and the support plate 6 is fixedly connected to two vertically symmetrically distributed connecting seats 7 on the side close to the mounting box 1, and the two connecting seats 7 are rotatably connected to the first connecting rod 4 and the second connecting rod 5.

[0031] Two symmetrically distributed mounting holes 8 are provided inside the support plate 6 , and a friction block 9 is fixedly connected to the side of the support plate 6 away from the mounting box 1 , and the friction blocks 9 are distributed in a matrix structure on the outside of the support plate 6 .

[0032] A rotating handle 11 is rotatably connected to the top of the installation box 1, and a rotating sleeve 12 is rotatably connected to both sides of the installation box 1, and the rotating sleeve 12 is located between the two mounting seats 3. The lower end of the rotating handle 11 extends to the inside of the installation box 1, and the end of the rotating sleeve 12 away from the support plate 6 is located inside the installation box 1.

[0033] The lower end of the rotating handle 11 and one end of the rotating sleeve 12 located inside the installation box 1 are both fixedly connected with bevel gears, and the bevel gears at the lower end of the rotating handle 11 and the bevel gears at the end of the rotating sleeve 12 are meshed with each other.

[0034] The rotating sleeve 12 is provided with a thread inside, and the rotating sleeve 12 is connected with a screw rod 10 through the thread. The end of the screw rod 10 away from the installation box 1 is fixedly connected to the middle of the inner side of the support plate 6.

[0035] A microseismic monitor 15 is fixedly connected to the inside of the mounting hole 8, and a wire 13 is fixedly connected to the side of the microseismic monitor 15 away from the support plate 6, and the end of the wire 13 away from the microseismic monitor 15 is fixedly connected to the remote communication module 2. The wire 13 is set to a flexible material, and protective rings 14 distributed at equal intervals are fixedly connected to the outside of the wire 13. Example

[0036] Based on the first embodiment, the specific working principle is as follows:

[0037] The microseismic monitoring safety device for mines has a handle fixedly connected to the top of the rotating handle 11. The rotating handle 11 is driven to rotate inside the installation box 1 by rotating the handle on the top of the rotating handle 11, so that the bevel gear at the bottom of the rotating handle 11 rotates inside the installation box 1, and then the rotating handle 11 drives the bevel gears at the ends of the two rotating sleeves 12 to rotate through the bevel gears at the bottom of the rotating handle 11. When the rotating sleeve 12 is rotating, the rotating sleeve 12 also rotates on the outside of the screw 10. The threads on the inside of the rotating sleeve 12 and the threads on the outside of the screw 10 are connected to each other, so that the rotating sleeve 12 can drive the screw 10 to move inside it during the rotation process. When the screw 10 is inside the rotating sleeve 12, When moving in the opposite direction toward the installation box 1, the length of the overall structure formed by the screw 10 and the rotating sleeve 12 will be shortened, so that the parallelogram structure formed by the second connecting rod 5 and the first connecting rod 4 is located at the connection between the two mounting seats 3 and the two connecting seats 7 and approaches each other. When the screw 10 moves in the opposite direction toward the installation box 1, the length of the overall structure formed by the screw 10 and the rotating sleeve 12 will increase, so that the parallelogram structure formed by the second connecting rod 5 and the first connecting rod 4 is located at the connection between the two mounting seats 3 and the two connecting seats 7 and moves away from each other, thereby adjusting the distance between the two support plates 6 and the installation box 1.

[0038] First, adjust the support plate 6 to the position closest to the installation box 1. At this time, both support plates 6 are in the position closest to the installation box 1, so that the distance between the support plates 6 at both ends of the device is minimized. At this time, install the device in the gap inside the mine. At this time, turn the rotating handle 11 to drive the two support plates 6 away from each other until the support plates 6 engage with the gap inside the mine to fix the device as a whole.

[0039] When the support plate 6 is engaged with the gap inside the mine, the microseismic monitor 15 connected to the support plate 6 through the two mounting holes 8 extends the cabinet mounting hole 8 to the side of the support plate 6 away from the mounting box 1, so that the microseismic monitor 15 is in close contact with the geological structure inside the mine. When vibration occurs inside the mine, the vibration will be collected by the microseismic monitor 15 and transmitted to the remote communication module 2 through the protective ring 14. The remote communication module 2 transmits the vibration data to the terminal device, realizing real-time monitoring of the vibration situation in the mine.

[0040] A plurality of annularly distributed protective rings 14 are fixedly connected to the outside of the wire 13 . The plurality of annularly distributed protective rings 14 form a protective structure outside the wire 13 to prevent the wire 13 from being compressed by the outside and thus damaged.
