[0029] Example

[0030] like Figure 1-3 As shown in the embodiment of this application, the monitoring and early warning device for coal mine geological disaster control includes a base 1, a connecting column 2, a support column 3, a snap-fit ​​mechanism 4, a GNSS displacement monitoring device body 5, and a locking mechanism 6. The connecting column 2 is mounted on the base 1 and has a slot 7. The lower end of the support column 3 is located in the slot 7. The connecting column 2 and the support column 3 are fixed together by the snap-fit ​​mechanism 4. The GNSS displacement monitoring device body 5 is fixed to the support column 3 by the locking mechanism 6.

[0031] When it is necessary to assemble the connecting column 2 and the support column 3, place the lower end of the support column 3 into the slot 7 and use the snap-fit ​​mechanism 4 to fix the connecting column 2 and the support column 3. When it is necessary to disassemble the connecting column 2 and the support column 3, release the snap-fit ​​mechanism 4 to fix the connecting column 2 and the support column 3, and the support column 3 can be pulled out. When it is necessary to install the GNSS displacement monitoring device body 5, use the locking mechanism 6 to fix the GNSS displacement monitoring device body 5 and the support column 3. When it is necessary to disassemble the GNSS displacement monitoring device body 5, release the locking mechanism 6 to fix the GNSS displacement monitoring device body 5 and the support column 3.

[0032] In this embodiment, the snap-fit ​​mechanism 4 includes a fixed sleeve 8, a fixed block 9, a snap-fit ​​block 10, a traction plate 11, and elastic elements 12. The fixed sleeve 8 is fixed to the outside of the connecting column 2 by at least two fixed blocks 9. A snap-fit ​​groove 13 is provided on the outer wall of the support column 3. One end of the snap-fit ​​block 10 is located in the snap-fit ​​groove 13, and the other end of the snap-fit ​​block 10 is sequentially movably inserted through the connecting column 2 and the fixed sleeve 8. The traction plate 11 is provided at the end of the snap-fit ​​block 10 away from the snap-fit ​​groove 13, and at least two elastic elements 12 are provided between the traction plate 11 and the fixed sleeve 8.

[0033] When it is necessary to assemble the connecting column 2 and the support column 3, pull the traction plate 11. Under the action of the traction plate 11, the elastic element 12 is stretched, and the lower end of the support column 3 is placed inside the slot 7. Then, release the traction plate 11, and the elastic element 12 rebounds and pushes one end of the locking block 10 into the slot 13, thereby achieving the connection and fixation of the connecting column 2 and the support column 3. When it is necessary to separate the connecting column 2 and the support column 3, pull the traction plate 11 to make the locking block 10 leave the slot 13, and the support column 3 can be pulled out, thereby achieving the separation of the connecting column 2 and the support column 3.

[0034] In this embodiment, there are two symmetrical slots 13 and two sets of locking mechanisms 4. The arrangement of the two sets of locking mechanisms 4 can improve the stability of the connection between the connecting column 2 and the support column 3.

[0035] In this embodiment, the snap-fit ​​mechanism 4 also includes a gripping ring 14, which is disposed on the traction plate 11. The gripping ring 14 facilitates the pulling of the traction plate 11.

[0036] In this embodiment, the elastic element 12 is a spring, which is easy to install and use.

[0037] In this embodiment, the locking mechanism 6 includes a threaded rod 15, a locking sleeve 16, and a limiting sleeve 17. The support column 3 is provided with a through hole 18. The locking sleeve 16 is movably inserted through the through hole 18. One end of the locking sleeve 16 is provided with the limiting sleeve 17. The other end of the locking sleeve 16 is threaded onto the threaded rod 15. The threaded rod 15 is fixedly installed on the GNSS displacement monitoring device body 5. The support column 3 is located between the GNSS displacement monitoring device body 5 and the limiting sleeve 17.

[0038] When the GNSS displacement monitoring device body 5 needs to be disassembled, simply rotate the locking sleeve 16 to separate the locking sleeve 16 from the threaded rod 15. When the GNSS displacement monitoring device body 5 needs to be installed, first place the threaded rod 15 into the through hole 18, then align the locking sleeve 16 with the threaded rod 15, and then rotate the locking sleeve 16 to screw the locking sleeve 16 onto the threaded rod 15, thereby fixing the GNSS displacement monitoring device body 5.

[0039] In this embodiment, the locking sleeve 16 has an external thread, and the limiting sleeve 17 is threaded onto the locking sleeve 16. The threaded connection facilitates the assembly between the limiting sleeve 17 and the locking sleeve 16, and allows the installation position of the limiting sleeve 17 on the locking sleeve 16 to be adjusted according to usage requirements.

[0040] In this embodiment, in order to reduce energy consumption, a solar power supply device 19 is provided on the support column 3. The solar power supply device 19 includes a triangular bracket 20, a clamp 21, a solar panel 22, and an energy storage device 23. The triangular bracket 20 is fixedly connected to the support column 3 through multiple clamps 21. The solar panel 22 and the energy storage device 23 are both installed on the triangular bracket 20. The energy storage device 23 is electrically connected to the main body 5 of the GNSS displacement monitoring device. When in use, the solar panel 22 converts solar energy into electrical energy, and the energy storage device 23 stores the electrical energy and uses it to power the main body 5 of the GNSS displacement monitoring device.

[0041] In this embodiment, the base 1 is provided with a plurality of mounting holes 25 through which fixing nails 24 pass. In use, the base 1 is fixed by fixing nails 24.

[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
