Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a forest fire prevention and reconnaissance UAV with a clamping mechanism. Background Technology

[0002] In modern times, in order to facilitate forest fire prevention surveys, it is necessary to conduct regular forest surveys. However, manual surveys are inefficient. Therefore, drones are needed to carry out large-scale surveys and improve the efficiency of forest surveys.

[0003] Utility model patent CN218172579U discloses a forest fire detection and rescue drone, including a drone body, a detection camera mounted on the side of the drone body, and a bracket fixed to the bottom of the drone body. The bracket is equipped with a pulling and clamping mechanism for securing rescue supplies, and an adjustable buffer mechanism for cushioning and protecting the drone body. This utility model relates to the field of drone technology. This forest fire detection and rescue drone, through the pulling and clamping mechanism, facilitates the clamping and securing of rescue supplies, thereby enabling the transport of rescue supplies. The anti-slip components increase friction with the rescue supplies, preventing them from falling during transport and improving safety. The buffer plate and buffer spring provide cushioning protection for the drone body upon landing, reducing the possibility of damage to the drone body.

[0004] However, the aforementioned forest fire detection and rescue drones only use a single electric telescopic rod in conjunction with two opposing clamping plates to hold and secure supplies. During drone flight, especially when encountering airflow disturbances or long-distance flights, the rescue supplies are only secured by the side clamping plates, with no support at the bottom, making them prone to shaking or even loosening. This not only affects the drone's flight stability but may also cause the rescue supplies to fall during transport, increasing the risk of the rescue mission. Furthermore, when the bottom area of ​​the supplies is large and the center of gravity is low, relying solely on the side clamps cannot guarantee their stability during flight, making them prone to shifting or tipping over due to an unstable center of gravity. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model proposes a forest fire prevention and exploration drone with a clamping mechanism to solve the aforementioned problems.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A forest fire prevention and reconnaissance drone with a clamping mechanism includes a drone body, a clamping mechanism at the bottom of the drone body, a detection camera installed at the bottom of the drone body, and two supports fixed at the bottom of the drone body.

[0008] The clamping mechanism includes a drive housing, with two square bracket arc-shaped plates disposed below the drive housing. The square bracket arc-shaped plates on both sides are arranged opposite to each other. The drive housing is provided with a drive structure for moving the square bracket arc-shaped plates towards each other. A screw is rotatably connected to the top of the inner wall of the square bracket arc-shaped plate. A threaded sleeve is threaded onto the surface of the screw. The bottom of the screw passes through the square bracket arc-shaped plate and is fixed with a handwheel. A bottom support plate is fixed to the surface of the threaded sleeve. A sliding groove is formed on the surface of the square bracket arc-shaped plate, and the bottom support plate is slidably connected to the surface of the sliding groove.

[0009] Preferably, the internal driving structure of the drive housing includes two bidirectional lead screws, which are rotatably connected to the inner wall of the drive housing. Two movable platforms are threadedly connected to the surface of the bidirectional lead screws. Two through slots are formed on the bottom surface of the drive housing. The movable platforms are slidably connected to the surface of the through slots. A geared motor is fixed on the surface of the drive housing. The output shaft of the geared motor passes through the drive housing and is fixedly connected to one side of the bidirectional lead screw. The bottom of the movable platform is fixedly connected to the top of the square bracket arc plate.

[0010] Preferably, one end of the bidirectional lead screw extends through the drive housing and is fixed with a transmission wheel. The two transmission wheels on both sides are connected by belt drive. The transmission wheels are timing belt pulleys, and the belts used to drive the two transmission wheels on both sides are timing belts.

[0011] Preferably, the inner wall of the square arc-shaped plate is fixed with multiple reinforcing ribs.

[0012] Preferably, rubber friction pads are fixed to both the surface of the square arc plate and the bottom of the drive housing.

[0013] Preferably, telescopic covers are fixed on both sides of the surface of the movable platform, and one end of the telescopic cover is fixedly connected to one side of the inner wall of the through groove.

[0014] Preferably, a guide rod is fixed to the inner wall of the groove, and the guide rod slides through the bottom support plate.

[0015] Compared with existing technologies, the beneficial effects of this utility model of a forest fire prevention and reconnaissance drone with a clamping mechanism are:

[0016] First, the clamping mechanism improves the stability and safety of the drone when transporting relief supplies. This design adds a bottom support plate to fix the bottom of the supplies, effectively solving the problem that the bottom of the supplies cannot be effectively fixed. During the drone's flight, especially when encountering airflow disturbances or when long-distance flight is required, the supplies can be more firmly fixed, greatly reducing the risk of the supplies shaking, loosening, or even falling.

[0017] Secondly, when the geared motor starts, it will drive the bidirectional lead screw connected to it to rotate, which will cause the movable table threaded on the bidirectional lead screw to slide along the through groove. Since the bottom of the movable table is fixedly connected to the top of the square bracket arc plate, the movement of the movable table will drive the square bracket arc plate to move in opposite directions, thereby realizing the clamping or releasing action of the material.

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] For a specific embodiment of a forest fire prevention and reconnaissance drone with a clamping mechanism, please refer to [link to specific implementation details]. Figures 1-4 It includes the drone body 1, a clamping mechanism 2 at the bottom of the drone body 1, a detection camera 3 installed at the bottom of the drone body 1, and two brackets 4 fixed at the bottom of the drone body 1.

[0025] The clamping mechanism 2 includes a drive housing 201. Two square bracket arc plates 205 are arranged below the drive housing 201. The square bracket arc plates 205 are arranged opposite to each other. The drive housing 201 is provided with a drive structure for moving the square bracket arc plates 205 toward each other. A screw 206 is rotatably connected to the top of the inner wall of the square bracket arc plate 205. A threaded sleeve 208 is threaded to the surface of the screw 206. The bottom of the screw 206 passes through the square bracket arc plate 205 and is fixed with a handwheel 207. A bottom support plate 209 is fixed to the surface of the threaded sleeve 208. A sliding groove 210 is opened on the surface of the square bracket arc plate 205. The bottom support plate 209 is slidably connected to the surface of the sliding groove 210.

[0026] Through the above technical solution, the drive shell 201 at the bottom of the UAV body 1 serves as the core component. Two square bracket-shaped plates 205 arranged opposite each other are positioned below the drive shell 201. Through the drive structure inside the drive shell 201, the square bracket-shaped plates 205 on both sides can move towards each other. This design allows for the clamping of materials not only by the square bracket-shaped plates 205 from both sides, but also by the effective support and fixation of the bottom of the materials through the bottom support plate 209. When materials need to be fixed, the drive structure first moves the square bracket-shaped plates 205 towards each other, clamping the materials in the middle, and then... The moving screw 206 raises the bottom support plate 209 until it is tightly attached to the bottom of the material, thus achieving all-round fixation of the material. This clamping mechanism 2 design greatly improves the stability and safety of the UAV when transporting relief supplies. This design increases the fixation of the bottom of the material by the bottom support plate 209, effectively solving the problem that the bottom of the material cannot be effectively fixed. During the flight of the UAV, especially when encountering airflow disturbances or when long-distance flight is required, the material can be more firmly fixed, greatly reducing the risk of the material shaking, loosening or even falling.

[0027] The internal drive structure of the drive housing 201 includes two bidirectional lead screws 202, which are rotatably connected to the inner wall of the drive housing 201. Two movable platforms 204 are threadedly connected to the surface of the bidirectional lead screws 202. Two through slots are opened on the bottom surface of the drive housing 201, and the movable platforms 204 are slidably connected to the surface of the through slots. A geared motor 203 is fixed on the surface of the drive housing 201. The output shaft of the geared motor 203 passes through the drive housing 201 and is fixedly connected to one side of the bidirectional lead screw 202. The bottom of the movable platform 204 is fixedly connected to the top of the square bracket arc plate 205.

[0028] With the above technical solution, when the geared motor 203 starts, it will drive the bidirectional lead screw 202 connected to it to rotate, thereby causing the movable table 204 threaded on the bidirectional lead screw 202 to slide along the through groove. Since the bottom of the movable table 204 is fixedly connected to the top of the square bracket arc plate 205, the movement of the movable table 204 will drive the square bracket arc plate 205 to move in the opposite direction, thereby realizing the clamping or releasing action of the material.

[0029] One end of the bidirectional lead screw 202 extends through the drive housing 201 and is fixed with a transmission wheel 211. The two transmission wheels 211 are connected by belt drive. The transmission wheel 211 is a timing belt pulley, and the belt used for driving the two transmission wheels 211 is a timing belt.

[0030] Through the above technical solution, when the geared motor 203 drives the bidirectional lead screw 202 on one side to rotate, the transmission wheel 211 at the end of the bidirectional lead screw 202 also rotates accordingly. Through the transmission of the timing belt, the transmission wheel 211 on the other side will also rotate synchronously, thereby driving the bidirectional lead screw 202 on the other side to rotate synchronously. This ensures that the movable tables 204 and the square bracket arc plate 205 on both sides can move synchronously in opposite directions, ensuring accurate and coordinated clamping of materials. The transmission method of timing pulley and timing belt can achieve precise synchronous rotation of the bidirectional lead screw 202 on both sides. The cooperation of timing pulley and timing belt has the advantages of high transmission accuracy, good stability, and non-slippage, which can ensure that the moving speed and position of the square bracket arc plate 205 on both sides are always consistent, thereby avoiding the situation where the materials tilt or are damaged due to uneven force on both sides when clamping materials.

[0031] The inner wall of the square arc plate 205 is fixed with multiple reinforcing ribs 214.

[0032] Through the above technical solution, by setting multiple reinforcing ribs 214 on the inner wall of the square bracket arc plate 205, these reinforcing ribs 214 can effectively disperse and bear part of the stress, making the square bracket arc plate 205 more robust when under force, and less prone to deformation or damage, thereby ensuring that the clamping mechanism 2 works stably and reliably for a long time and ensuring the safety of rescue materials throughout the transportation process.

[0033] Rubber friction pads 212 are fixed on both the surface of the square arc plate 205 and the bottom of the drive housing 201.

[0034] Through the above technical solution, the rubber friction pad 212 is closely attached to the surface of the material. Its good elasticity can adapt to the slight unevenness of the material surface and increase the actual contact area between the pad and the material.

[0035] Telescopic covers 215 are fixed on both sides of the surface of the movable platform 204, and one end of the telescopic cover 215 is fixedly connected to one side of the inner wall of the through groove.

[0036] With the above technical solution, as the movable platform 204 slides along the through groove, the telescopic cover 215 will extend and retract accordingly. When the movable platform 204 moves to one end of the through groove, the telescopic cover 215 extends accordingly, covering the gap between the through groove and the movable platform 204, preventing external pollutants such as dust, debris, and moisture from entering.

[0037] A guide rod 213 is fixed to the inner wall of the slide 210, and the guide rod 213 slides through the bottom support plate 209.

[0038] With the above technical solution, when the screw 206 rotates and drives the screw sleeve 208 to move up and down, the bottom support plate 209 can rise or fall smoothly along the slide groove 210 under the guidance of the guide rod 213, thereby accurately supporting and fixing the bottom of the material.

[0039] Its working principle is as follows: When performing a mission, this forest fire prevention and exploration drone first uses the detection camera 3 installed on its bottom to monitor and explore the forest area for fire. When relief supplies need to be transported, the supplies are placed on top of the bottom support plates 209 on both sides. Then, the reduction motor 203 is started, which drives the bidirectional lead screw 202 on one side to rotate. Since a transmission wheel 211 is fixed at one end of the bidirectional lead screw 202, and the two transmission wheels 211 are connected by a timing belt, the bidirectional lead screw 202 on the other side will also rotate synchronously. When the bidirectional lead screw 202 rotates, the movable platform 204 threaded to its surface will slide along the through groove at the bottom of the drive housing 201, thereby driving the square bracket arc plate 205 to move towards each other, clamping the relief supplies between the two square bracket arc plates 205. At the same time, the screw 206 located at the top of the inner wall of the square bracket arc plate 205 can be rotated by the handwheel 207 when needed. The screw sleeve 208 on the surface of the screw 206 drives the bottom support plate 209 to rise along the slide groove 210 until the bottom support plate 209 is tightly attached to the bottom of the supplies, and the top of the supplies is in contact with the rubber friction pad 212 at the bottom of the drive housing 201, thus achieving all-round fixation of the supplies. Throughout the process, the rubber friction pad 212 increases the friction with the supplies, preventing them from slipping. After loading is complete, the drone takes off for the target location. During flight, the clamping mechanism 2 continuously and stably secures the supplies, ensuring safe transport. Upon arrival at the target location, the reverse operation of the reduction motor 203 and screw 206 causes the square bracket arc plate 205 and bottom support plate 209 to release the supplies, completing the delivery of the relief supplies.

[0040] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
