[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Embodiment 1

[0037] See also Figure 1-2A mining geological disaster monitoring and early warning device, comprising a frame assembly 1, the frame assembly 1 comprising: a base 11, a support rod 12 is arranged on the top of the support rod 12, a monitoring and early warning device 13 is arranged on the top of the support rod 12, a fixing assembly 2 is arranged on the base 11 and the support rod 12, the fixing assembly 2 comprises: a motor 21, arranged on the inner top surface of the support rod 12, a screw rod 22, fixedly connected to the bottom output end of the motor 21, a fixing rod 23, threadedly connected to the outside of the screw rod 22, a through hole for the fixing rod 23 to move is opened at the bottom of the base 11 and the support rod 12, a limit plate 24 is arranged on the outer wall of the fixing rod 23, and its outer wall is slidably arranged in the slide groove of the inner wall of the support rod 12 through a slider, and a protective mechanism 25 is arranged on the top of the base 11. The part of the fixing rod 23 extending into the ground is in a pointed shape. A brush sleeve 3 is arranged on the inner wall of the through hole opened at the center of the base 11. The protection mechanism 25 includes: a protection frame 251, which is slidably set on the top of the base 11, a spring 252, which is symmetrically set on the inner wall of the protection frame 251, a pressure plate 253, which is set at the end of the spring 252 away from the protection frame 251, and its facing surface is in contact with the outer wall of the support rod 12, and a through groove 254 is set through the top of the protection frame 251.

[0038] When in use, the device is placed at a place near a mine that needs to be monitored, and is fixed by means of a fixing assembly 2: a driving motor 21 is used, the motor 21 drives the screw rod 22 to rotate, and a fixing rod 23 connected to the external thread of the screw rod 22 is affected by the rotation of the screw rod 22, moves downward, and is gradually inserted into the ground through the through holes on the support rod 12 and the base 11, thereby completing the fixation of the base 11 to the ground. The pointed design at the bottom of the fixing rod 23 facilitates the fixing rod 23 to be quickly extended into the ground. When the fixing rod 23 descends, the limit plates 24 at both ends thereof slide along the inner wall of the support rod 12 with the help of the slider, thereby preventing the fixing rod 23 from rotating along with the rotation of the screw rod 22, thereby affecting the effect of the fixing rod 23 extending into the ground. When the monitoring position needs to be changed, the motor 21 is reversed to pull the fixed rod 23 out of the ground, and the brush sleeve 3 cleans the soil adhered to the bottom of the fixed rod 23 to prevent the fixed rod 23 from bringing the soil into the support rod 12 and affecting the normal use next time. The protective mechanism 25 protects the support rod 12: when the outside of the protective frame 251 encounters an impact, the protective frame 251 moves within the movable range of the through groove 254, and the spring 252 buffers the impact force to prevent the impact force from directly exerting force on the support rod 12, causing the support rod 12 to tilt, affecting the accuracy of the monitoring results of the monitoring early warning device 13 at its top.

[0039] Embodiment 2

[0040] On the basis of the first embodiment, an auxiliary function is added.

[0041] See also Figure 1-2 A displacement sensor 26 is provided at the contact position between the base 11 and the protection frame 251, and a buzzer 27 is provided at the left side of the top of the protection frame 251. The displacement sensor 26 is electrically connected to the buzzer 27. Here, the displacement sensor 26 model may be LWH-0200. When the protection frame 251 is moved by the impact force, the displacement sensor 26 detects the movement of the protection frame 251 and sends a signal to the buzzer 27. The buzzer 27 makes a sound to drive away the damaging wild animals, thereby increasing the service life of the device. The spring 252 and the pressure plate 253 are arranged at multiple locations around the circumference, and at least at four locations, so as to buffer the protection frame 251 in at least four directions, thereby achieving a better protection effect. An accordion shell 255 is provided between the through slot 254 and the outer wall of the support rod 12. The accordion shell 255 expands and contracts when the protection frame 251 moves, so as to prevent the through slot 254 from being exposed to the outside, and rainwater or debris from entering the protection frame 251, thereby affecting the normal use of the protection frame 251. The height of the protection frame 251 is the same as that of the support rod 12. The protection frame 251 completely covers the support rod 12 to prevent the appearance of a protection blind spot outside the support rod 12, thereby increasing the service life of the equipment.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
