Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 The present invention provides the following technical solution: an online monitoring and early warning device for mine rockburst, including a pressure gauge 1 and a display screen 2 installed on the surface of the pressure gauge 1. At the same time, an alarm light is installed inside the display screen 2 to provide early warning and alarm. The tail end of the pressure gauge 1 is connected to a signal receiving antenna 3, and the side of the pressure gauge 1 is connected to a connecting line 4. The other end of the connecting line 4 is connected to a stress sensor 5.

[0024] A limiting clamp 6 is connected to the surface of the connecting line 4. A threaded rod 7 is connected through the top surface of the limiting clamp 6. A receiving block 8 is connected to the bottom end of the threaded rod 7. A rotating block 9 is connected to the surface of the threaded rod 7 near the receiving block 8. A pressing block 10 is connected to the bottom surface of the receiving block 8. A guide block 11 is connected to one side of the pressing block 10.

[0025] Preferably, the threaded rod 7 is threadedly connected to the limiting clamp 6, and the threaded rod 7 forms a rotating structure through the opening on the surface of the rotating block 9 and the receiving block 8.

[0026] In practical use, by rotating the threaded rod 7, the rotating block 9 can be easily rotated along the opening on the surface of the receiving block 8, thereby facilitating the up-and-down movement of the extrusion block 10.

[0027] Preferably, the extrusion block 10 is made of PVC material, and the arc of the bottom opening of the extrusion block 10 matches the surface arc of the connecting line 4.

[0028] In practical use, the extrusion block 10 facilitates the extrusion and winding of the connecting wire 4, thereby making it easier to store the connecting wire 4, avoiding random placement and potential safety hazards, and improving the safety of use.

[0029] Preferably, the guide block 11 has a T-shaped structure, and the guide block 11 and the opening on the side of the limiting clamp 6 form a sliding connection structure.

[0030] In practical use, the guide block 11 is slid along the opening on the side of the limiting clamp 6 to facilitate the up and down movement of the compression block 10.

[0031] Preferably, a fixing block 12 is connected to one side of the pressure gauge 1, a docking plate 13 is connected to the inner side of the fixing block 12, and a portable handle 14 is connected to the surface of the docking plate 13.

[0032] In practical use, the portable handle 14 allows operators to hold the pressure gauge 1 to monitor and read data on the rock pressure in the mining environment in real time, thus improving the ease of use.

[0033] Preferably, a locking spring 15 is connected to the inner wall of the opening on one side of the docking plate 13 near the fixing block 12, and a linkage plate 16 is connected to the other end of the locking spring 15.

[0035] The working principle of this utility model is as follows: The connecting wire 4 of the pressure gauge 1 is placed inside the opening on the surface of the limiting clamp 6. Then, the threaded rod 7 is rotated, causing the rotating block 9 to rotate along the opening on the surface of the receiving block 8. This causes the pressing block 10 to move downwards inside the limiting clamp 6, while simultaneously causing the guide block 11 on the side of the pressing block 10 to slide along the opening on the side of the limiting clamp 6. This facilitates the stable winding of the connected wire 4. At this point, the pressure gauge 1 is installed at the mine site to monitor rockburst, preventing the connected wire 4 from being placed haphazardly and improving the safety of the monitoring area. The system ensures the safety and stability of the data. In addition, by connecting the docking plate 13 at one end of the portable handle 14 to the fixing block 12, it is convenient to assemble the portable handle 14 on one side of the pressure gauge 1. At this time, the linkage plate 16 at one end of the locking block 17 is driven to squeeze the locking spring 15, thereby causing the locking spring 15 to deform. Then, the locking block 17 on one side of the linkage plate 16 is fitted into the opening on one side of the fixing block 12, which makes it convenient to install the portable handle 14 stably. This makes it convenient for the operator to hold the pressure gauge 1 to monitor and read the impact pressure of the mine environment in real time, thus improving the ease of use.
