Specific implementation mode

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0027] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a geological disaster monitoring device for coal mining subsidence areas, including a fixed seat 1, a control box 2 is fixedly installed on the top of the fixed seat 1, fixed pipes 3 are fixed on the sides of the fixed seat 1, a support arm 4 is fixedly installed inside the fixed pipe 3, a drive motor 5 is fixed at one end of the support arm 4, a rotor 6 is installed on the drive motor 5, a support pipe 7 is fixed at one end of the fixed pipe 3, a movable frame 9 is movably installed on the support pipe 7, an opening 8 is formed on the support pipe 7, a support base 10 is fixedly installed at the bottom of the fixed seat 1, the rotation of the rotor 6 pushes the air flow downward to facilitate the lifting of the machine body. When the rotor 6 pushes the air flow downward, the air flow enters the inside of the support pipe 7 through the opening 8 under the thrust, which is convenient for cooling the fixed seat 1.

[0028] In this embodiment, limit seats 11 are movably installed at both ends of the support base 10, slots 12 are formed on the limit seats 11, a fixed groove 22 is formed on the inner wall of the support base 10, a fixed block 23 is movably installed inside the fixed groove 22, a mounting seat 15 is fixed at one end of the fixed block 23, a heat absorption plate 16 is fixed on the top of the mounting seat 15, a mounting groove 17 is formed at the bottom of the mounting seat 15, a motor cavity 29 is formed inside the mounting seat 15, a rotating motor 30 is fixedly installed inside the motor cavity 29, an output shaft 31 is installed on the rotating motor 30, the rotating motor 30 rotates through the output shaft 31, and the output shaft 31 drives the camera 28 to rotate back and forth inside the mounting groove 17 through the connection seat 27 to monitor the ground.

[0029] In this embodiment, a cavity 13 is formed at the top of the support base 10, and air outlet holes 14 are formed on the side of the cavity 13. The air outlet holes 14 are installed between the heat absorption plates 16. Limit grooves 18 are formed at both ends of the support base 10. A damper 19 is fixed inside the limit grooves 18. A support mechanism 20 is movably installed on the side of the damper 19. A limit block 21 is fixed at one end of the damper 19 and the support mechanism 20. One end of the limit block 21 is fixed on the limit seat 11. A limit disc 24 is fixed at one end of the support tube 7. A torsion spring 25 is fixed on the inner wall of the limit disc 24. The support mechanism 20 is a support spring. The support spring cooperates with the damper 19 to buffer and damp the up and down movement of the limit seat 11. Under the push of the support mechanism 20, the limit seat 11 moves downward to limit and fix the fixed block 23.

[0030] In this embodiment, a connection cavity 26 is formed inside the fixed seat 1. One end of the connection cavity 26 is connected to the support tube 7, and the other end of the connection cavity 26 is connected to the cavity 13. A connection seat 27 is fixed at one end of the output shaft 31. A camera 28 is fixedly installed on the connection seat 27. The connection seat 27 is movably installed inside the installation groove 17. An installation hole is formed on the inner wall of the movable frame 9. One end of the torsion spring 25 is fixed inside the installation hole. The movable frame 9 rotates and tilts on the support tube 7 through the torsion spring 25. The torsion spring 25 enables the movable frame 9 to move slowly on the support tube 7. After the movable frame 9 moves, the torsion spring 25 drives the movable frame 9 to return to its original position for use. The movable frame 9 shields and protects the bottom of the drive motor 5 and the rotor 6.

[0031] When the device is in use, first move the limit seat 11 at one end of the support seat 10 upward simultaneously. After the limit seat 11 moves upward, the limit block 21 squeezes the support mechanism 20 and the damper 19. After the limit block 21 moves upward to the maximum distance, the limit seat 11 stops moving. After the limit seat 11 stops moving, the slot 12 and the fixing slot 22 are horizontally distributed. Install the fixing block 23 on the mounting seat 15 inside the slot 12 and the fixing slot 22. The mounting seat 15 drives the fixing block 23 to slide and install between the support seats 10. When the mounting seat 15 slides and installs, the limit seat 11 loses the support of the fixing block 23. Under the push of the support mechanism 20, the limit seat 11 moves downward. After the limit seat 11 moves downward, the slot 12 and the fixing slot 22 are vertically displaced. One side of the limit seat 11 contacts the fixing block 23 for limit fixation. In the future, when the limit seat 11 moves upward, it is convenient for the quick disassembly of the mounting seat 15. After the mounting seat 15 is installed, start the driving motor 5 to make the rotor 6 rotate. Under the rotation of the rotor 6, the whole device is driven to fly. During the flight of the drone, the connecting seat 27 is driven to rotate by the rotating motor 30, and the connecting seat 27 drives the camera 28 to rotate back and forth inside the mounting groove 17 to monitor the ground. Through the drone and the remote sensing technology components, taking the working face as the object of investigation and monitoring for the geological disasters of coal mining ground subsidence, research work such as drone aerial photography, image processing, interpretation of ground subsidence cracks, calculation of surface subsidence amount, and analysis of ground subsidence law has been carried out. The movable frame 9 is distributed at the bottom of the driving motor 5 and the rotor 6 through the support pipe 7. The movable frame 9 shields and protects the position of the rotor 6. Under the push of the air flow when the rotor 6 rotates, it enters the opening 8. The air flow flows through the opening 8 inside the support pipe 7 and then enters the inside of the connecting cavity 26 inside the fixed seat 1. Then it enters the cavity 13 through the connecting cavity 26. Finally, the air flow is discharged from the air outlet hole 14 to cool the whole mounting seat 15. The top of the mounting seat 15 absorbs heat through the heat absorption plate 16, and the air flow flows on the side of the heat absorption plate 16 for cooling. In addition, when the fixed seat 1 is tilted, the movable frame 9 is buffered and tilted through the torsion spring 25, thus avoiding the damage to the rotor 6 caused by the tilt of the fixed seat 1.
