Description

Technical Field

[0001] This invention relates to a geological disaster early warning device, and more particularly to a mine geological disaster early warning device with shock absorption effect. Background Technology

[0002] During the mining process, open-pit mines are susceptible to geological disasters such as landslides, debris flows, and rockfalls due to factors such as heavy rainfall, earthquakes, and human intervention. Landslides, debris flows, and rockfalls, influenced by gravitational potential energy, continue to move downwards, causing widespread damage. Therefore, the use of early warning devices is crucial. Existing early warning devices, designed to mitigate the damage caused by these geological disasters, typically incorporate protective and shock-absorbing mechanisms. However, their protective and shock-absorbing effects are poor. Especially during debris flows, they are easily overturned and destroyed, rendering them ineffective. While they can absorb shocks from rockfalls, they often fail to remove the rocks promptly, leading to accumulation and compromising stability. Subsequent impacts significantly increase the probability of further damage. Furthermore, existing early warning devices, when monitoring visible geological disasters using surveillance cameras, are less effective at night due to insufficient light, resulting in poor early warning performance. Using artificial lighting requires a large illumination area, leading to high energy consumption and highlighting the limitations of current technology. Summary of the Invention

[0003] The purpose of this invention is to provide a mine geological disaster early warning device with shock absorption effect, so as to solve the technical problems of poor protection effect, shock absorption effect and nighttime early warning effect of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A mine geological disaster early warning device with shock absorption effect includes a monitoring part, which includes a support frame, a monitoring camera, a controller, a central control system, and an alarm device. The monitoring camera and controller are fixed to the upper part of the support frame, and a non-rotating inner support cylinder is installed at the bottom. The inner support cylinder wraps around the bottom perimeter of the support frame and is coaxially rotatably connected to an outer support cylinder. A hollow airbag is fixed to the outside of the outer support cylinder. The airbag is a vertical cylinder, and horizontal intermediate compression springs are fixed between its inner wall and the outer wall of the outer support cylinder. The airbag is eccentrically positioned relative to the outer support cylinder, and an arc-shaped receiving groove is fixed to its bottom. The airbag tends to maintain its cylindrical shape under the elastic repulsive force of the intermediate compression springs. The receiving groove is coaxially positioned relative to the outer support cylinder, and an arc-shaped lower guide rod is coaxially fixed within the receiving groove. A horizontal support plate is fixed to the bottom of the support cylinder, and a vertical support plate is fixed to the top of the support plate. The support plate is interlocked in the receiving groove and is horizontally slidably connected to the lower guide rod. Lower compression springs are fixed to the left and right ends of the support plate, interlocked outside the lower guide rod. The other ends of the two lower compression springs are fixed to the left and right sides of the receiving groove respectively, and are always in an elastic compression state. Under the elastic repulsive force of the lower compression springs, the support plate tends to be located in the middle of the receiving groove. The monitoring camera is electrically connected to the controller, which is externally powered and transmits signals to the central control system via wired connection. The central control system includes an alarm device. The central control system is responsible for summarizing the real-time images transmitted from the monitoring camera and using image recognition algorithms for calculation and identification. When a visible geological disaster is identified, the alarm device will sound an alarm.

[0005] Based on the above technical solution, the top of the airbag is fixedly connected to a lower air inlet pipe and a lower air outlet pipe. One-way valves are fixedly connected to the lower air inlet pipe and the lower air outlet pipe respectively. The one-way valve in the lower air inlet pipe only allows gas to enter the airbag, and the one-way valve in the lower air outlet pipe only allows gas to exit the airbag.

[0006] Based on the above technical solution, a cylinder is fixed inside the support frame. An upper exhaust pipe is fixedly connected to the upper part of the cylinder, and an upper intake pipe is fixedly connected to the bottom. The upper exhaust pipe and the upper intake pipe pass through the support frame. A sealing piston is slidably connected to the upper and lower parts of the cylinder. A tension spring is fixed to the bottom of the cylinder inner wall together with the sealing piston. Under the elastic tension of the tension spring, the piston always tends to move closer to the bottom of the cylinder. A self-reset button switch is fixed to the top of the cylinder inner wall. The sealing piston can press the self-reset button switch upward. The self-reset button switch is electrically connected to the controller. When the self-reset button switch is pressed, the controller counts. When the self-reset button switch is reset, the controller stops counting and clears the count. The lower exhaust pipe is connected to the upper intake pipe through an excess flexible hose. When the sealing piston presses the self-reset button switch, the upper exhaust pipe is below the sealing piston, and the sealing piston is always above the upper intake pipe.

[0007] Based on the above technical solution, a horizontal platform is fixed to the top of the support frame, and a protective cover is hinged to the front of the platform. The protective cover is in the shape of an inverted semi-circle, and its virtual hinge axis is horizontally arranged in the left-right direction. A horizontal support base is fixed to the front of the protective cover, and an arc-shaped upper guide rod is fixed together with the support base and the protective cover. The upper guide rod is coaxial with the virtual hinge axis of the protective cover and is slidably connected to the platform. An upper compression spring is fixed to the inner wall of the protective cover, which is interposed with the upper guide rod. The bottom end of the upper compression spring abuts against the top of the platform. A power supply is fixed to the rear of the protective cover. A magnet is used. A second electromagnet is fixed at the rear of the platform. The first and second electromagnets are electrically connected to the controller and are positioned vertically opposite each other. The first and second electromagnets can magnetically attract each other, causing the cover to cover the platform. A water pressure sensor is fixed at the top of the inner wall of the cover and is electrically connected to the controller. When the first and second electromagnets are magnetically attracted, the upper compression spring is in an elastic compression state. When the magnetic attraction between the first and second electromagnets is released, the cover can flip forward, causing the bottom of the support base to come into contact with the bottom of the platform.

[0008] Based on the above technical solution, a horizontal limiting ring is fixed at the top of the platform, and a waterproof drone is placed there. The drone can be positioned within the space after the platform and the protective cover are closed. The drone is placed within the limiting ring and carries a battery pack and an onboard camera. The drone's electronic control system is electrically connected to the battery pack and the onboard camera. The drone's electronic control system is electrically connected to the controller via a power transmission component. The drone can freely switch between battery power and controller power. The drone's electronic control system and the main control system are each equipped with a radio transmission module for mutual radio signal transmission. The main control system's radio transmission module transmits radio signals to control the drone's electronic control system. The drone is equipped with an ultrasonic sensor transmitter. The platform... An ultrasonic sensor receiver is fixedly mounted. The ultrasonic sensor transmitter is electrically connected to the UAV's electronic control system. The ultrasonic sensor receiver is electrically connected to the controller. The power transmission assembly includes an upper power supply line, a lower power supply line, a plug, a socket, a No. 3 electromagnet, and a No. 4 electromagnet. Both the upper and lower power supply lines are insulated flexible wires. One end of the upper power supply line is electrically connected to the UAV's electronic control system, and the other end is electrically connected to the plug. One end of the lower power supply line is electrically connected to the controller, and the other end is electrically connected to the socket. The plug can be freely inserted into or unplugged from the socket. When the socket is inserted into the plug, an electrical connection is achieved. The plug is fixedly and electrically connected to a No. 3 electromagnet, and the socket is fixedly and electrically connected to a No. 4 electromagnet.

[0009] Based on the above technical solution, the mine geological disaster early warning device further includes a marking part, which includes a mounting base, a support rod, a spherical shell, a generator, a battery, a control module, a bracket, an LED light, a wind cup bracket, a wind cup, and a scraper. A vertical support rod is fixed to the top of the mounting base, and a transparent spherical shell is fixed to the upper part of the support rod. A generator is fixed to the top of the support rod, and a battery, a control module, and a bracket are fixed to the upper part of the support rod. An LED light is fixed to the outside of the bracket. The generator, battery, control module, and LED light are electrically connected. The rotating shaft of the generator passes through the spherical shell and is rotatably connected to it in a sealed manner. A wind cup bracket is coaxially fixed to the rotating shaft of the generator. Multiple wind cups are fixed at equal angles around the circumference of the wind cup bracket. A vertical arc-shaped scraper is also fixed to the bottom of the wind cup bracket, and the scraper is in contact with the outer wall of the spherical shell.

[0010] Based on the above technical solution, a luminous panel is attached and fixed to the upper and lower parts of the inner wall of the spherical shell. The luminous panel can emit light on its own at night. An annular gap is left between the two luminous panels. The LED light is ring-shaped, and the annular gap between the LED light and the luminous panel is horizontally corresponding.

[0011] Based on the above technical solution, the inner support cylinder is slidably connected to the support frame, the bottom end of the support frame is fixed with a horizontal base, the base and the mounting seat are respectively provided with multiple mounting holes, the top edge of the base is fixed with a support ring, the top of the support ring can fit against the bottom end of the support plate so that there is a gap between the bottom end of the support plate and the top end of the base.

[0012] Compared with the prior art, the present invention has the following advantages: When the rolling stones, debris flows, or landslides continue to move downwards under the action of gravitational potential energy and collide with the airbag during the use of the present invention, since the airbag is eccentrically set relative to the outer support cylinder, it can be seen through force analysis that there is a tendency for the airbag to rotate, thereby changing the direction of movement of the impacting rolling stones, debris flows, and landslides, making them easier to discharge and less prone to accumulation, thereby reducing the damage and vibration caused by head-on impact; on the other hand, after the impact, the impact part of the airbag contracts and recovers under the elastic repulsive force of the central compression spring, that is, soft contact is achieved, which causes less damage and has a better protective effect compared to hard contact.

[0013] The system utilizes a lower intake pipe, lower exhaust pipe, one-way valve, cylinder, upper exhaust pipe, upper intake pipe, sealed piston, and tension spring to achieve a damping effect, thus reducing vibration to the surveillance camera compared to hard contact. By determining the trigger time of the self-reset button switch, the type of geological disaster can be identified at night when observation is difficult, thereby improving the effectiveness of nighttime early warning.

[0014] The system collects rainwater using an extended protective cover. At this time, the water pressure sensor starts working, and the controller also starts timing. By monitoring the water pressure measured at different time periods, the rainfall in the corresponding time period in the area can be inferred, thereby determining the risk level and grade of another mudslide and improving the early warning effect.

[0015] By utilizing drones, power transmission components, ultrasonic sensor transmitters, and ultrasonic sensor receivers, drones can be kept hovering and at a suitable distance from the platform. This reduces or even eliminates the impact of geological disasters on the airborne camera, greatly improving shock absorption and making the recorded images more stable, thus enhancing the early warning effect.

[0016] The markings can distinguish between normal and abnormal areas, while the flashing LEDs and light panels are highly visible at night, thus improving the effectiveness of nighttime monitoring and early warning while also reducing energy consumption and making it more energy-efficient and environmentally friendly.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1-9As shown, a mine geological disaster early warning device with shock absorption effect includes a monitoring part, which includes a support frame 2, a monitoring camera 3, a controller 4, a central control system, and an alarm device. The monitoring camera 3 and the controller 4 are fixed on the upper part of the support frame 2, and a non-rotating inner support cylinder 5 is installed at the bottom. The inner support cylinder 5 wraps around the bottom of the support frame 2 and is coaxially rotatably connected to an outer support cylinder 6. A hollow airbag 7 is fixed to the outside of the outer support cylinder 6. The airbag 7 is a vertical cylinder, and horizontal intermediate compression springs 8 are fixed between the inner wall and the outer wall of the outer support cylinder 6. The airbag 7 is eccentrically positioned relative to the outer support cylinder 6, and an arc-shaped receiving groove 9 is fixed at the bottom. The airbag 7 tends to maintain its cylindrical shape under the elastic repulsive force of the intermediate compression springs 8. The receiving groove 9 is coaxially positioned relative to the outer support cylinder 6, and an arc-shaped lower guide rod 10 is coaxially fixed inside the receiving groove 9. A horizontal support is fixed at the bottom of the inner support cylinder 5. The support plate 11 has a vertical support plate 12 fixed at its top. The support plate 12 is interlocked in the receiving groove 9 and is horizontally slidably connected to the lower guide rod 10. Lower compression springs 13 are fixed at both ends of the support plate 12, interlocked outside the lower guide rod 10. The other ends of the two lower compression springs 13 are fixed to the left and right sides of the receiving groove 9 respectively and are always in an elastic compression state. Under the elastic repulsive force of the lower compression springs 13, the support plate 12 tends to be located in the middle of the receiving groove 9. The monitoring camera 3 is electrically connected to the controller 4. The controller 4 is externally powered and transmits signals to the central control system via wired connection. The central control system includes an alarm device, which is a known prior art device, such as a warning light and a buzzer. The central control system is responsible for summarizing the real-time images transmitted from the monitoring camera 3 and using image recognition algorithms for calculation and identification. When a visible geological disaster is identified, the alarm device will sound an alarm.

[0029] When using, fix the support frame 2 vertically in the area to be monitored in the mine, and follow the instructions in the attached document. Figure 9The schematic fixed support frame 2, that is, the line A connecting the part of the airbag 7 close to the support frame 2 and the part of the airbag 7 away from the support frame 2 is nearly perpendicular to the tilt direction B of the mine slope. When a rockfall, debris flow or landslide occurs, the monitoring camera 3 collects real-time images and uses the central control system to identify and calculate, thereby determining whether a geological disaster has occurred. Then, the alarm device is used to issue an alarm and warn relevant personnel in the surrounding area where no geological disaster has occurred. When rocks, debris flows, or landslides continue to move downwards under the influence of gravitational potential energy and impact the airbag 7, since the airbag 7 is eccentrically positioned relative to the outer support cylinder 6, force analysis shows that it tends to rotate. This changes the direction of movement of the impacting rocks, debris flows, and landslides, making them easier to expel and less prone to accumulation, thereby reducing damage and vibration from head-on impacts. After the airbag 7 drives the outer support cylinder 6 to rotate, it resets under the elastic repulsive force of the lower compression spring 13. On the other hand, after impact, the impact area of ​​the airbag 7 contracts and recovers under the elastic repulsive force of the middle compression spring 8, thus achieving soft contact. Compared to hard contact, this results in less damage and better protection.

[0030] The top of the airbag 7 is fixedly connected to a lower air intake pipe 16 and a lower exhaust pipe 17. A one-way valve 18 is fixedly connected to the lower air intake pipe 16 and the lower exhaust pipe 17 respectively. The one-way valve 18 in the lower air intake pipe 16 only allows gas to enter the airbag 7, and the one-way valve 18 in the lower exhaust pipe 17 only allows gas to exit the airbag 7.

[0031] Furthermore, when the airbag 7 is impacted, the gas inside is compressed and discharged through the one-way valve 18 and the lower exhaust pipe 17. When it recovers under the elastic repulsive force of the lower compression spring 13, the gas from the outside is drawn into the airbag 7 through the lower air intake pipe 16 and the one-way valve 18, thus achieving a damping effect and buffering effect. Compared with hard contact, it can reduce the vibration of the monitoring camera 3.

[0032] A cylinder 19 is fixed inside the support frame 2. An upper exhaust pipe 20 is fixedly connected to the upper part of the cylinder 19, and an upper intake pipe 21 is fixedly connected to the bottom. The upper exhaust pipe 20 and the upper intake pipe 21 respectively pass through the support frame 2. A sealing piston 22 is slidably connected to the upper and lower parts of the cylinder 19. A tension spring 23 is fixed to both the sealing piston 22 and the bottom of the inner wall of the cylinder 19, and under the elastic tension of the tension spring 23, the piston tends to move closer to the bottom of the cylinder 19. A self-resetting button switch 24 is fixed to the top of the inner wall of the cylinder 19. The sealing piston 2... 2. The self-reset button switch 24 can be pressed upwards. The self-reset button switch 24 is electrically connected to the controller 4. When the self-reset button switch 24 is pressed, the controller 4 counts the presses. When the self-reset button switch 24 is reset, the controller 4 stops counting and clears the count. The lower exhaust pipe 17 is connected to the upper intake pipe 21 through the excess flexible hose. When the sealing piston 22 presses the self-reset button switch 24, the upper exhaust pipe 20 is located below the sealing piston 22. The sealing piston 22 is always located above the upper intake pipe 21.

[0033] Furthermore, when a falling rock impacts the airbag 7, the airbag 7 rotates and contracts simultaneously, thus expelling air in a shorter time. However, when a mudslide or landslide impacts the airbag 7, it is less likely to roll, resulting in a longer air expulsion time. When the airbag 7 expels air, the air enters the cylinder 19 through the lower exhaust pipe 17, the one-way valve 18, and the upper intake pipe 21. This air then pushes the sealed piston 22 upwards against the tension spring 23, causing the sealed piston 22 to press the self-reset button switch 24. Simultaneously, gas is expelled through the upper exhaust pipe 20. This achieves a damping effect, and by determining the trigger time of the self-reset button switch 24, the type of geological disaster can be determined at night when observation is difficult, thereby improving the effectiveness of nighttime early warning.

[0034] A horizontal platform 25 is fixed to the top of the support frame 2. A protective cover 26 is hinged to the front of the platform 25. The protective cover 26 is an inverted semi-circle, and its virtual hinge axis is horizontally arranged in the left-right direction. A horizontal support base 27 is fixed to the front end of the protective cover 26. An arc-shaped upper guide rod 28 is fixed together with the support base 27 and the protective cover 26. The upper guide rod 28 is coaxial with the virtual hinge axis of the protective cover 26 and is slidably connected to the platform 25. An upper compression spring 29 is fixed to the inner wall of the protective cover 26, which is inserted into the upper guide rod 28 with a gap. The bottom end of the upper compression spring 29 abuts against the top of the platform 25. An electromagnet 30 is fixed to the rear of the protective cover 26. A second electromagnet 31 is fixed to the rear of platform 25. The first electromagnet 30 and the second electromagnet 31 are electrically connected to the controller 4 and are vertically aligned. The first electromagnet 30 and the second electromagnet 31 can magnetically attract each other, so that the cover 26 covers the platform 25. A water pressure sensor 32 is fixed to the top of the inner wall of the cover 26. The water pressure sensor 32 is electrically connected to the controller 4. When the first electromagnet 30 and the second electromagnet 31 are magnetically attracted, the upper compression spring 29 is in an elastic compression state. When the magnetic attraction between the first electromagnet 30 and the second electromagnet 31 is released, the cover 26 can flip forward so that the bottom of the support 27 is in contact with the bottom of the platform 25.

[0035] Furthermore, during normal operation, electromagnets 30 and 31 are energized and magnetically attracted to each other, thus maintaining the cover 26 and platform 25 in a closed state. At this time, the upper compression spring 29 is in an elastic compression state. When a debris flow geological disaster is detected, the controller 4 automatically controls the electromagnets 30 and 31 to be de-energized. At this time, under the elastic repulsive force of the upper compression spring 29, the cover 26 unfolds forward and the support 27 contacts and adheres to the bottom of the platform 25, so that the cover 26 can open upward to receive rainwater. At this time, the water pressure sensor 32 starts to work, and the controller 4 also starts timing. By monitoring the water pressure measured at different time periods, the rainfall in the corresponding time period in the area can be inferred, thereby judging the risk level and grade of another debris flow and improving the early warning effect.

[0036] A horizontal limiting ring 33 is fixed to the top of the platform 25, and a waterproof drone 34 is placed thereon. The waterproof drone 34 is a known prior art technology, such as the Swift drone. The drone 34 can be positioned within the space after the platform 25 and the protective cover 26 are closed. The drone 34 is placed within the limiting ring 33 and carries a battery pack and an onboard camera. The electronic control system of the drone 34 is electrically connected to the battery pack and the onboard camera. The electronic control system of the drone 34 is electrically connected to the controller 4 via a power transmission component. The drone 34 can freely switch between being powered by the battery pack or by the controller 4. The electronic control system and the main control system of the drone 34 are each equipped with a radio transmission module for mutual radio signal transmission. The main control system's radio transmission module transmits radio signals to control the electronic control system of the drone 34. The drone 34 is fixed with an ultrasonic sensor transmitter 38. The platform 25... An ultrasonic sensor receiver 39 is fixedly mounted. The ultrasonic sensor transmitter 38 is electrically connected to the electronic control system of the UAV 34. The ultrasonic sensor receiver 39 is electrically connected to the controller 4. The power transmission assembly includes an upper power supply line 40, a lower power supply line 41, a plug 42, a socket 43, a No. 3 electromagnet 44, and a No. 4 electromagnet 45. The upper power supply line 40 and the lower power supply line 41 are both flexible wires with insulated outer sheaths. One end of the upper power supply line 40 is electrically connected to the electronic control system of the UAV 34, and the other end is electrically connected to the plug 42. One end of the lower power supply line 41 is electrically connected to the controller 4, and the other end is electrically connected to the socket 43. The plug 42 can be freely plugged into or unplugged from the socket 43. When the socket 43 is plugged into the plug 42, an electrical connection is achieved. The plug 42 is fixedly and electrically connected to the No. 3 electromagnet 44, and the socket 43 is fixedly and electrically connected to the No. 4 electromagnet 45.

[0037] Furthermore, during normal use, socket 43 and plug 42 are connected, and electromagnets 44 and 45 are energized and magnetically attracted to each other. When the protective cover 26 is deployed, controller 4 controls drone 34 to take off and hover. By measuring the distance through ultrasonic sensor transmitter 38 and ultrasonic sensor receiver 39, the corresponding distance between drone 34 and platform 25 can be inferred, ensuring that this distance is always less than the total length of the power transmission assembly, i.e., the power transmission assembly is in a relaxed state at this time. At this time, the monitoring camera 3 and the onboard camera carried by drone 34 are used to record images, and both images are transmitted to the central control system for recognition and calculation. At this time, even if the monitoring camera 3 vibrates due to impact, the impact has no effect on the drone. The impact of the onboard camera carried by the drone 34 is also minimal, thus reducing camera vibration and making the recorded images more stable, thereby improving the early warning effect for geological disasters. When it is determined that mudslides and rockfalls are frequent, the monitoring camera 3 vibrates more frequently and the risk of being destroyed by geological disasters increases. In this case, the controller 4 automatically controls the third electromagnet 44, the fourth electromagnet 45 and the ultrasonic sensor receiver 39 to cut off the current, and the main control system controls the drone 34 to rise. At this time, the drone 34 can rely entirely on its onboard camera to record and transmit images in real time, basically avoiding the impact of geological disasters, greatly improving the shock absorption effect, making the recorded images more stable, and thus improving the early warning effect.

[0038] The mine geological disaster early warning device also includes a marking section, which comprises a mounting base 47, a support rod 48, a spherical shell 49, a generator 50, a battery 51, a control module 52, a bracket 61, an LED light 53, a wind cup bracket 54, a wind cup 55, and a scraper 56. A vertical support rod 48 is fixed to the top of the mounting base 47, and a transparent spherical shell 49 is fixed to the upper part of the support rod 48. The generator 50 is fixed to the top of the support rod 48, and the battery 51, control module 52, and bracket 61 are fixed to the upper part of the support rod 48. Both the controller 4 and the control module 52 are... In known existing technologies, such as microcontrollers and PLCs, an LED light 53 is fixed to the outside of the bracket 61. The generator 50, the battery 51, the control module 52 and the LED light 53 are electrically connected. The rotating shaft of the generator 50 passes through the spherical shell 49 and is sealed and rotatably connected to the spherical shell 49. A wind cup bracket 54 is coaxially fixed to the rotating shaft of the generator 50. Multiple wind cups 55 are fixed at equal angles around the circumference of the wind cup bracket 54. A vertical arc-shaped scraper 56 is also fixed to the bottom of the wind cup bracket 54. The scraper 56 is in contact with the outer wall of the spherical shell 49.

[0039] Furthermore, the markings are fixed at certain intervals within the mining area. Natural wind blows through the wind cups 55, causing the generator 50 to rotate and generate electricity. After processing by the control module 52, the electricity is used to charge the battery 51. The control module 52 controls the LED lights 53 to flash regularly. When no geological disaster occurs, the markings will work normally without any accidents. At this time, the monitoring camera 3 or the airborne camera can observe the flashing of the LED lights 53, indicating that the area is normal. However, when a geological disaster occurs, the probability of the markings being damaged increases significantly. At this time, the monitoring camera 3 or the airborne camera cannot observe the flashing of the LED lights 53, indicating that the area is abnormal, thus requiring focused monitoring or early warning. The flashing of the LED lights 53 is very conspicuous at night, thus improving the nighttime monitoring and early warning effect, while also reducing power consumption and making it more energy-efficient and environmentally friendly. When the natural wind blows the wind cup 55, it drives the scraper 56 to move circumferentially through the wind cup bracket 54 to clean the outer wall of the spherical shell 49, thereby ensuring the light transmission effect of the spherical shell 49 and allowing the light of the LED light 53 to be observed by the monitoring camera 3 and the airborne camera for a long time, while reducing the interference of dust.

[0040] The upper and lower parts of the inner wall of the spherical shell 49 are each fitted with a luminous plate 57. The luminous plate 57 can emit light on its own at night. There is an annular gap between the two luminous plates 57. The LED light 53 is ring-shaped. The annular gap between the LED light 53 and the luminous plate 57 is horizontally aligned.

[0041] Furthermore, when the battery 51 is insufficient to store enough energy to prevent the LED light 53 from flashing, and during the flashing intervals of the LED light 53, the luminous panel 57 can emit light on its own and be observed by the monitoring camera 3 or the airborne camera, thereby improving the monitoring effect at night.

[0042] The inner support cylinder 5 is slidably connected to the support frame 2. The bottom end of the support frame 2 is fixed with a horizontal base 58. The base 58 and the mounting base 47 are respectively provided with multiple mounting holes 59. The outer edge of the top end of the base 58 is fixed with a support ring 60. The top end of the support ring 60 can fit against the bottom end of the support plate 11, so that there is a gap between the bottom end of the support plate 11 and the top end of the base 58.

[0043] The base 58 and mounting base 47 are fixed to the mine by bolts or expansion bolts through the mounting holes 59. The gap between the bottom of the support plate 11 and the top of the base 58 is for accommodating the bolt heads. The inner support cylinder 5 slides down and closes to the base 58 under the action of gravity, so that the airbag 7 can better protect the bottom of the support frame 2.

[0044] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
