[0021] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0022] This specific embodiment provides a long-distance rescue drone with a throwing claw, which solves the problem in the prior art that the drone's downward-looking fill light control method cannot achieve airdrop when the drone is abnormal.
[0023] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the utility model as set forth in the claims.
[0024] Reference Figures 1-4The utility model provides a long-distance rescue drone with a casting claw, comprising a main body 1 and a claw 2 mounted on the main body 1, the claw 2 being used to grab objects. In order to facilitate the fixing of the claw, a servo 14, a transmission assembly 6, and a pull rod 5 are provided at the bottom of the main body 1. A first notch 7 and a second notch 8 are provided at the bottom of the main body 1, wherein both ends of the transmission assembly 6 are respectively connected to the servo 14 and the pull rod 5. The servo 14 rotates to drive the transmission assembly 6 to rotate, and then drives the pull rod 5 to move. Specifically, the pull rod 5 passes through the first notch 7 and the second notch 8 in sequence, and the first end of the claw 2 is arranged on the pull rod 5 at the position of the first notch 7, and the second end is arranged on the pull rod 5 at the position of the second notch 8. When people use it, the pull rod 5 passes through the first notch 7 and the second notch 8 at the same time, wherein the first end of the claw 2 is sleeved on the pull rod 5 at the position of the first notch 7. In order to prevent the claw 2 from colliding with or getting hooked on obstacles during the movement of the claw 2 for grabbing objects, the second end of the claw 2 is sleeved on the pull rod 5 at the position of the second notch 8, thereby reducing the length of the claw 2 in the vertical direction. In this way, after fixing the claw 2, flight safety can be improved, and the claw 2 can be prevented from being entangled with obstacles or wires, or from being blown by the wind during flight and the inertia of flight entangled with the blades of the drone, causing the drone to explode and crash. destruction; when it is transported to the designated location, the servo 14 rotates, driving the pull rod 5 to move, so that the pull rod 5 set at the position of the second notch 8 is retracted, so that the second end of the claw 2 falls off, and the claw 2 can be opened to put down the material; when the claw 2 is entangled on an obstacle, in order to reduce losses, the claw 2 is discarded and the main body 1 of the drone is retained. The servo 14 can continue to rotate to disengage the pull rod 5 from the first notch 7 on the main body 1, so that the first end of the claw 2 is separated from the main body 1, thereby realizing the falling off of the claw 2, and at the same time making it convenient for people to control the main body 1 to fly back to reduce losses.
[0025] Further optimization scheme, in order to facilitate the transmission component 6 to drive the pull rod 5 to move, such as Figure 1 As shown, the transmission assembly 6 includes a first connecting rod 61 and a second connecting rod 62. The first end of the first connecting rod 61 is connected to the servo 14, the second end of the first connecting rod 61 is hinged to the first end of the second connecting rod 62, and the second end of the second connecting rod 62 is hinged to the pull rod 5. As the servo 14 rotates to drive the first connecting rod 61 to rotate, the first connecting rod 61 drives the second connecting rod 62 to move, and the pull rod 5 moves horizontally under the drive of the second connecting rod 62, thereby causing the claws 2 to detach from the pull rod 5 in turn, making it convenient for the claws 2 to fall off.
[0026] To further optimize the solution, the transmission assembly 6 is not limited to the connecting rod assembly, and the transmission assembly 6 can also be a gear rack set, wherein the gear of the gear rack set is connected to the servo 14, and one end of the rack of the gear rack set is connected to the pull rod 5. The servo 14 rotates and then the gear rotates. The rotation of the gear drives the rack to move in the horizontal direction, thereby driving the pull rod 5 to move in the horizontal direction, so that the two ends of the claw can fall off in sequence.
[0027] To further optimize the solution, in order to ensure that the pull rod 5 can move in the horizontal direction, a limit ring is provided on the main body 1, and the limit ring is used to limit the pull rod 5, ensuring that the pull rod 5 moves in the direction limited by the limit ring, reducing the probability of deviation.
[0028] To further optimize the solution, in order to ensure that the pull rod 5 can stop moving when it moves to a certain position, a photoelectric sensor is provided between the first notch 7 and the second notch 8. The photoelectric sensor is electrically connected to the servo 14. When the drone moves to the specified position and needs to parachute, the servo 14 starts and drives the pull rod 5 to move to the right in sequence. When the photoelectric sensor detects the end of the pull rod 5, the photoelectric sensor transmits the detection signal to the servo 14, and the servo 14 stops rotating according to the signal, thereby causing the second end of the claw 2 to separate from the pull rod 5.
[0029] A further optimized solution is that the claw 2 includes a connecting rope and a claw that can be opened and closed. The claw is connected to the second end of the connecting rope. The first end of the connecting rope is provided with a first connecting ring 3, and the claw is provided with a second connecting ring 4. The first connecting ring 3 and the second connecting ring 4 are sleeved on the pull rod 5. In this way, the amplitude of the claw shaking is reduced, thereby reducing the probability of the connecting rope being entangled on an obstacle.
[0030] To further optimize the solution, in order to facilitate the control of the movement of the main body 1, a first central processing unit 11, a wireless transmitting device 12, a first battery 13, and a photosensitive electrical group 16 are provided on the main body 1. The first battery 13 supplies power to the first central processing unit 11, and the first central processing unit 11 is electrically connected to the servo 14 and the wireless transmitting device 12. This makes it convenient for the first central processing unit 11 to control the wireless transmitting device 12 to transmit signals and control the rotation of the servo 14.
[0031] To further optimize the solution, in order to facilitate the movement of the claw 2, a wireless receiving device 21, a second central processing unit 22, a first electric motor 23, and a second battery 24 are provided on the claw 2. The second battery 24 supplies power to the second central processing unit 22. The second central processing unit 22 is electrically connected to the first electric motor 23 and the wireless receiving device 21. The wireless receiving device 21 is used to receive the signal of the wireless transmitting device 12 and transmit the received signal to the second central processing unit 22. The second central processing unit 22 controls the movement of the first electric motor 23 to open or close the claw 2, so as to facilitate the control of the claw to grab and put down objects.
[0032] Specifically, the photoresistor 15 on the drone body 1 is mounted below the drone's downward-facing fill light. When the drone's remote control turns the downward-facing fill light on or off, it detects the light's on / off status and converts it into a level signal, which is then transmitted via the wireless transmitter circuit. When the electric claw's wireless receiver 21 receives the on / off level signal, it is input into the second central processing unit 22 for processing. After processing, the electric claw drive circuit drives the first electric motor 23 forward / reverse, thereby opening and closing the claw. If the claw 2 becomes entangled in an obstacle such as a tree branch, the drone can be discarded to ensure its safety. At this point, the drone's remote control can control the number of times the downward-facing fill light turns on and off, outputting an angle signal from the servo 14 to the first central processor 11, causing the pull rod 5 to move left to the position of the first notch 7, thereby airdropping the electric claw and self-rescuing the drone.
