[0002] Drones are commonly used tools in geological surveys. For some complex geology, drones are usually used in conjunction with geological survey cameras for remote remote survey operations, which can greatly reduce the workload of surveyors and improve survey efficiency.

[0003] When conducting geological surveys, drones often need to operate in complex and changeable terrain environments, such as mountains, canyons, swamps, etc., and collisions are very likely to occur when flying in these complex terrains. Generally, existing devices basically install a circle of flexible guardrails on the surface of the drone during flight. Due to the softness of the guardrails, when the drone collides, the guardrails are easy to collide with the propellers of the drone.

[0016] The present invention has the following beneficial effects:

[0017] 1. According to the present invention, when the main body collides during flight, the concentrated point of the collision will be on the semicircular ring. After the semicircular ring is collided, the impact force generated by the collision will impact the moving plate, so that the moving plate drives the pushing plate to move. When the pushing plate moves, it will drive the rotating shaft to rotate. When the rotating shaft rotates, the rotating rotating shaft will drive the fixed ring to rotate. When the fixed ring rotates, it will pull the sliding plate to make the sliding plate and the hollow plate tilt. When the sliding plate and the hollow plate tilt, the hollow plate will rotate on the outer surface of the fixed rod. When the sliding plate and the hollow plate tilt, the fixed ring will pull the sliding plate to slide inside the hollow plate. When the sliding plate slides, the sliding sliding plate will pull the bottom of the arc plate to move up. Since the top of the arc plate is fixedly connected to the side wall of the hollow plate, when the sliding plate pulls the arc plate to rise, the arc plate will be deformed. After the arc plate is deformed, the middle part of the arc plate will produce When a bulge occurs, the raised arc plate will push the telescopic plate. When the telescopic plate is pushed by the arc plate, the telescopic plate will extend out of the outer wall of the hose, and when the sliding plate slides inside the hollow plate, the sliding sliding plate will generate rubbing force on the surface of the elastic plastic rope. After the elastic plastic rope is subjected to the rubbing force, it will be twisted and twisted. Since the elastic plastic rope runs through the side walls of other hollow plates and is fixed to other hoses, the surface of the elastic plastic rope will increase after being rubbed, and the length of the elastic plastic rope will become shorter after being rubbed. At this time, the shortened elastic plastic rope will pull the remaining hoses to concentrate, and the telescopic plate extending outward will reduce the impact force of direct collision in the buffer space between the device and the external object, thereby protecting the drone from damage, and at the same time, it can avoid the impact force from being concentrated on a certain local area of ​​the drone, reducing the damage caused by excessive local force.

[0018] 2. In the present invention, when the elastic plastic rope becomes shorter after being rubbed, the shortened elastic plastic rope will pull the C-shaped frame to rotate on the surface of the second connecting rod. When the C-shaped frame rotates, the rotating C-shaped frame will push the elastic plate to move through the second pushing plate. When the elastic plate moves, it will push the arc-shaped inclined plate 1 and the arc-shaped inclined plate 2 to move. Since there are a plurality of arc-shaped inclined plates 1 and 2, when the arc-shaped inclined plates 1 and 2 move, the arc-shaped inclined plates 1 and 2 will move relatively close to each other. When the arc-shaped inclined plates When arc-shaped inclined plate 1 and arc-shaped inclined plate 2 move closer, the C-shaped frame at the connection between arc-shaped inclined plate 1 and arc-shaped inclined plate 2 will also move closer. When the C-shaped frame moves closer, it will push the protective shaft to move through spring rod 2. When the protective shaft moves, it will cover the detector. Through the covering of the protective shaft, when the device collides, the covered protective shaft can provide additional protection and support on the surface of the detector, so that the detector can maintain its position and direction relatively stably, ensuring its function and accuracy from external interference, and ensuring the continuity and accuracy of UAV data collection.

[0019] 3. In the present invention, when the elastic plate pushes the arc-shaped inclined plate 1 and the arc-shaped inclined plate 2 to move, the moving arc-shaped inclined plate 1 and the arc-shaped inclined plate 2 will move back and forth up and down at the wave groove on the surface of the semicircular groove through the telescopic rod. When the telescopic rod moves up and down, the moving telescopic rod surface periodically squeezes the rotating ring. After being squeezed, the rotating ring will swing on the surface of the inner cylinder. When the rotating ring swings, the cleaning ring will be pushed by the spring rod to swing with the rotating ring. When the cleaning ring swings, the inner wall of the cleaning ring will be swung on the surface of the detector for cleaning. At the same time, when the cleaning ring swings, it can also reduce the situation where gravel splashes on the surface of the detector after the device is hit. In addition, when the cleaning ring swings, it can clean the dust on the surface of the detector. The swing of the cleaning ring can reduce the splashing of small stones onto the surface of the detector while cleaning the dust on the surface of the detector, thereby reducing the dust falling on the surface of the detector after the impact and affecting the detection clarity of subsequent detector detection, thereby enhancing the subsequent detection accuracy and detection effect of the detector.

[0041] The hollow frame 501 is provided with a cleaning mechanism 6 inside. The cleaning mechanism 6 includes an elastic plate 601 rotatably connected to the side of the push plate 2 405 close to the connecting rod 101. A plurality of arc-shaped inclined plates 602 are provided on the side of the elastic plate 601 away from the push plate 2 405. A plurality of arc-shaped inclined plates 603 are provided on the end of the elastic plate 601 away from the push plate 2 405. The arc-shaped inclined plates 602 are arranged in a cross pattern. The arc-shaped inclined plates 603 close to the elastic plate 601 are arranged in a cross pattern. 2 is fixedly connected with a circular shaft, and the rotating C-shaped frame 402 will push the elastic plate 601 to move through the pushing plate 2 405, and the elastic plate 601 will push the arc-shaped inclined plate 1 602 and the arc-shaped inclined plate 2 603 to move when moving. Since there are a plurality of arc-shaped inclined plates 1 602 and arc-shaped inclined plates 2 603, when the arc-shaped inclined plates 1 602 and the arc-shaped inclined plates 2 603 move, the arc-shaped inclined plates 1 602 and the arc-shaped inclined plates 2 603 will move relatively close to each other.

[0042] The circular shaft passes through the side wall of the arc groove 503 and is rotatably connected to the elastic plate 601. The connection between the arc inclined plate 1 602 and the middle part of the arc inclined plate 2 603 is rotatably connected with a C-shaped frame 604. The C-shaped frame 604 passes through the side wall of the arc inclined plate 2 603 and extends to the outside. The two C-shaped frames 604 are rotatably connected with a spring rod 2 605. When the arc inclined plate 1 602 and the arc inclined plate 2 603 are brought closer, the C-shaped frame 604 at the connection between the arc inclined plate 1 602 and the arc inclined plate 2 603 will also be brought closer. When the C-shaped frame 604 is brought closer, it will push the protective shaft 606 to move through the spring rod 2 605, and when the protective shaft 606 moves, it will cover the detector 7.

When the telescopic rod 607 moves up and down, the surface of the moving telescopic rod 607 periodically squeezes the rotating ring 505.

[0044] When in use, when the main body 1 collides during flight, the collision focus will be on the semicircular ring 104. After the semicircular ring 104 is collided, the impact force generated by the collision will impact the movable plate 204, so that the movable plate 204 drives the push plate 203 to move. When the push plate 203 moves, it drives the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, the rotating rotating shaft 202 drives the fixed ring 205 to rotate. When the fixed ring 205 rotates, it pulls the sliding plate 301 to make the sliding plate 301 and the hollow plate 302 tilt. When the sliding plate When the sliding plate 301 and the hollow plate 302 are tilted, the hollow plate 302 will rotate on the outer surface of the fixing rod 102. When the sliding plate 301 and the hollow plate 302 are tilted, the fixing ring 205 will pull the sliding plate 301 to slide inside the hollow plate 302. When the sliding plate 301 slides, the sliding sliding plate 301 will pull the bottom of the arc plate 304 to move upward. Since the top of the arc plate 304 is fixedly connected to the side wall of the hollow plate 302, when the sliding plate 301 pulls the arc plate 304 to rise, the arc plate 304 will be deformed. After the curved plate 304 is deformed, a bulge will appear in the middle of the curved plate 304. At this time, the bulged curved plate 304 will push the telescopic plate 306. When the telescopic plate 306 is pushed by the curved plate 304, the telescopic plate 306 will extend out of the outer wall of the hose 103. When the sliding plate 301 slides inside the hollow plate 302, the sliding sliding plate 301 will generate a rubbing force on the surface of the elastic plastic rope 401. After the rubbing force is applied, the elastic plastic rope 401 will be twisted and twisted. Since the elastic plastic rope 401 passes through the other hollow plates 302, the elastic plastic rope 401 will be twisted and twisted. 2 and fixed with other hoses 103, then when the elastic plastic rope 401 is rubbed, its surface will increase, and the length of the elastic plastic rope 401 will become shorter after being rubbed, then the shortened elastic plastic rope 401 will pull the remaining hoses 103 to concentrate, and at the same time, the telescopic plate 306 extending outward will be in the buffer space between the device and the external object, reducing the impact force of direct collision, thereby protecting the drone from damage, and at the same time, it can avoid the impact force from being concentrated on a certain local area of ​​the drone, reducing the damage caused by excessive local force.When the elastic plastic rope 401 becomes shorter after being rubbed, the shortened elastic plastic rope 401 will pull the C-shaped frame 402 to rotate on the surface of the second connecting rod 404. When the C-shaped frame 402 rotates, the rotating C-shaped frame 402 will push the elastic plate 601 to move through the pushing plate 2 405. When the elastic plate 601 moves, it will push the arc-shaped inclined plate 1 602 and the arc-shaped inclined plate 2 603 to move. Since there are a plurality of arc-shaped inclined plates 1 602 and the arc-shaped inclined plates 2 603, when the arc-shaped inclined plates 1 602 and the arc-shaped inclined plates 2 603 move, the arc-shaped inclined plates 1 602 and the arc-shaped inclined plates 2 603 will move relatively close to each other. When the arc-shaped inclined plate 1 602 and the arc-shaped inclined plate 2 603 are brought closer, the C-shaped frame 604 at the connection between the arc-shaped inclined plate 1 602 and the arc-shaped inclined plate 2 603 will also be brought closer. When the C-shaped frame 604 is brought closer, the protective shaft 606 will be pushed to move through the spring rod 2 605. When the protective shaft 606 moves, it will cover the detector 7. Through the covering of the protective shaft 606, when the device collides, the covered protective shaft 606 can provide additional protection and support on the surface of the detector 7, so that the detector 7 can maintain its position and direction relatively stably, ensuring that its function and accuracy are not disturbed by the outside world, and ensuring the continuity and accuracy of the drone data collection. When the elastic plate 601 pushes the arc-shaped inclined plate 1 602 and the arc-shaped inclined plate 2 603 to move, the moving arc-shaped inclined plate 1 602 and the arc-shaped inclined plate 2 603 will move reciprocatingly up and down at the wave groove on the surface of the semicircular groove 502 through the telescopic rod 607. When the telescopic rod 607 moves up and down, the surface of the moving telescopic rod 607 periodically squeezes the rotating ring 505. After being squeezed, the rotating ring 505 will swing on the surface of the inner cylinder 504. When the rotating ring 505 swings, the spring rod 506 will push the cleaning ring 507 to swing with the rotating ring 505. The cleaning ring 507 When swinging, the inner wall of the cleaning ring 507 will perform a swinging cleaning on the surface of the detector 7. At the same time, when the cleaning ring 507 swings, it can also reduce the situation where gravel splashes on the surface of the detector 7 after the device is hit. In addition, when the cleaning ring 507 swings, it can clean the dust on the surface of the detector 7. The swinging of the cleaning ring 507 can reduce the splashing of pebbles onto the surface of the detector 7 while cleaning the dust on the surface of the detector 7, thereby reducing the dust falling on the surface of the detector 7 after the impact and affecting the detection clarity of the subsequent detection of the detector 7, thereby enhancing the subsequent detection accuracy and detection effect of the detector 7.
