[0030] 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.
[0031] Reference Figure 1 - Figure 5The utility model provides an embodiment: a forest fire prevention and extinguishing surveying and emergency support drone, including a drone body 1, a protective shell 8 is fixedly connected to the bottom of the drone body 1, a slide groove 15 is provided on the left side of the protective shell 8, a fixing plate 12 is fixedly connected inside the protective shell 8, a motor 18 is fixedly connected to the left side of the fixing plate 12, a half-tooth column 13 is fixedly connected to the output end of the motor 18, a shell 10 is fixedly connected to the left side of the protective shell 8, a limiting groove 11 is provided on the front side of the shell 10, a gear ring 14 is slidably connected inside the slide groove 15, the half-tooth column 13 and the gear ring 14 are meshed and connected, a connecting rod 9 is fixedly connected to the front side of the gear ring 14, a brush 7 is fixedly connected to the end of the connecting rod 9 away from the gear ring 14, a connecting column 17 is fixedly connected to the top wall of the protective shell 8, and a fixing component for installing a camera 16 is arranged inside the connecting column 17. When the protective shell 8 at the front end of the camera 16 needs to be cleaned, the rotation of the motor 18 drives the half-tooth column 13 to rotate. When the half-tooth column 13 rotates to a certain angle, the gear ring 14 moves upward, and when it rotates to another angle, the gear ring 14 moves downward. The gear ring 14 slides up and down in the slide groove 15, thereby realizing reciprocating motion to drive the brush 7 to move up and down in the limit groove 11, so that the protective shell 8 is cleaned. When the drone falls accidentally, the protective shell 8 will have a buffering effect on the camera 16, thereby greatly reducing the loss.
[0032] Reference Figure 2 , Figure 4 and Figure 5 The fixing assembly includes a limit shell 4 and a positioning column 19. The limit shell 4 is fixedly connected to the inside of the connecting column 17. A latch 3 is slidably connected to the inside of the limit shell 4. A baffle 22 is fixedly connected to the outside of the latch 3. A spring 21 is sleeved on the outer periphery of the latch 3. A pull tab 20 is fixedly connected to one end of the latch 3. The bottom end of the positioning column 19 is fixedly connected to the top of the camera 16. The outside of the positioning column 19 is slidably connected to the inside of the connecting column 17. When the camera 16 needs to be replaced, the glass plate in front of the protective shell 8 is opened, and the pull tabs 20 on both sides of the connecting column 17 are pulled open. The spring 21 in the limit shell 4 is deformed accordingly, and the latch 3 in the positioning column 19 will be pulled out. When the new camera 16 is placed in the connecting column 17, the latch 3 will be inserted into the positioning column 19 under the action of the spring 21, which greatly reduces the replacement time and improves the work efficiency.
[0033] Reference Figure 4 and Figure 5 The outer side of the baffle 22 is slidably connected to the inside of the limiting shell 4, and the outer side of the latch 3 is inserted into the inside of the positioning column 19. When the pull tab 20 is toggled, the spring 21 fixed on the baffle 22 will slide inside the limiting shell 4 and then be squeezed, and the latch 3 will be pulled out of the positioning column 19. When the pull tab 20 is released, the latch 3 is inserted into the positioning column 19 under the action of the spring 21, which greatly improves the speed of replacing the camera 16 and improves the work efficiency.
[0034] Reference Figure 1 , both sides of the bottom of the drone body 1 are fixedly connected with landing gears 2. When the drone falls, the landing gear 2 will reduce the buffer for the drone, thereby protecting the internal structure of the drone and preventing damage caused by excessive impact.
[0035] Reference Figures 1 to 3 The outer side of the connecting rod 9 is slidably connected to the inside of the limiting groove 11. When the connecting rod 9 moves up and down, the limiting groove 11 limits the connecting rod 9 to move up and down, which greatly improves the stability of the connecting rod 9 when moving up and down.
[0036] Reference Figure 1 - Figure 4 The front end of the protective shell 8 is fixedly connected with a pipe groove 6, and an air intake pipe 5 is inserted into the pipe groove 6. The end of the air intake pipe 5 away from the pipe groove 6 is fixedly connected under the wing. When the wing rotates, part of the wind force generated will be sent to the air intake pipe 5 in the pipe groove 6 along the air intake pipe 5 under the wing, thereby cleaning the glass cover in front of the camera 16, effectively cleaning the interference of smoke and dust on the camera 16 in the event of a fire, and greatly improving the work efficiency.
[0037] Reference Figure 1 - Figure 4 The toothed ring 14 is slidably connected inside the slide groove 15. The front part of the protective shell 8 is made of glass, and the brush 7 and the protective shell 8 are in contact. When the protective shell 8 at the front end of the camera 16 needs to be cleaned, the rotation of the motor 18 drives the half-tooth column 13 to rotate. When the half-tooth column 13 rotates to a certain angle, the toothed ring 14 will move upward, and when it rotates to another angle, the toothed ring 14 will move downward. The toothed ring 14 will slide up and down in the slide groove 15, thereby realizing the reciprocating motion to drive the brush 7 to move up and down in the limit groove 11, so that the protective shell 8 is cleaned. When the drone falls accidentally, the protective shell 8 will have a buffering effect on the camera 16, thereby greatly reducing the loss.
[0038] Reference Figure 5 One end of the spring 21 is fixedly connected to one side of the baffle 22, and the other end of the spring 21 is fixedly connected to the inner wall of the connecting column 17. When the pull tab 20 is pulled open, the spring 21 will be compressed and pressed against the inner wall of the connecting column 17, so that the latch 3 will be pulled out of the positioning column 19. When the pull tab 20 is released, the latch 3 will be reinserted into the positioning column 19 under the action of the spring 21.
[0039] Working principle: When a fire occurs and a large amount of smoke and dust are generated that pollute the camera 16, the motor 18 starts to rotate, driving the half-tooth column 13 to rotate. When the half-tooth column 13 rotates to a certain angle, the gear ring 14 will move upward, and when it turns to another angle, the gear ring 14 will move downward. The gear ring 14 will slide up and down in the slide groove 15, thereby realizing reciprocating motion to drive the brush 7 to move up and down in the limit groove 11, so that the glass plate in front of the protective shell 8 will be cleaned. When the drone falls accidentally, the protective shell 8 will have a buffering effect on the camera 16, thereby greatly reducing the loss. When the camera 16 needs to be replaced, open the glass plate in front of the protective shell 8, pull the pull tabs 20 on both sides of the connecting column 17 open, and the spring 21 in the limit shell 4 will be deformed, and the pin 3 in the positioning column 19 will be pulled out. When the new camera 16 is placed in the connecting column 17, the pin 3 is inserted into the positioning column 19 under the action of the spring 21, which greatly reduces the replacement time and improves work efficiency.
