Description

Technical Field

[0001] This utility model relates to the field of low-altitude operation drones, and in particular to a low-altitude operation drone. Background Technology

[0002] Low-altitude unmanned aerial vehicles (UAVs) are unmanned aircraft that can fly in airspace below 1,000 meters above sea level and are characterized by lightweight design, intelligence, high efficiency, and strong environmental adaptability. In the field of environmental protection, UAVs play multiple roles due to their advantages of flexibility, high efficiency, precision, and strong data collection capabilities.

[0003] One method involves using a low-altitude drone to carry a water tank and spray fine water mist into the air or onto the ground through nozzles. This method adsorbs airborne dust particles or suppresses the spread of dust from ground sources. It avoids the dust suppression blind spots caused by the height or terrain limitations of traditional equipment, thus significantly improving dust suppression efficiency. This method has been widely used in various environmental dust suppression operations.

[0004] However, in order to improve the continuity of dust suppression operations and avoid the situation where the water tank runs out of water during dust suppression operations, the water tank is large in size and its own weight often exceeds ten kilograms. If the water tank is full of water, it reaches more than sixty kilograms. Moreover, the existing water tanks are generally mounted under the drone by a bracket, which means that when changing the water tank, the bracket and the drone must be separated first, and the empty water tank must be separated from the bracket. Then, the fully loaded water tank is fixed on the bracket, and finally the bracket and the drone are reconnected. There are problems with the difficulty of disassembling and assembling the large water tank and the drone, which affects the efficiency of the operation. Therefore, a low-altitude operation drone is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a low-altitude operation drone to solve the problem mentioned in the background art of the difficulty in assembling and disassembling the large-volume water tank and the drone, which affects the operation efficiency. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A low-altitude operation drone includes a drone body, a water tank located below the drone body, support rods on both sides of the water tank, and a positioning mechanism for fixing the position of the water tank between the two support rods. The positioning mechanism includes a load-bearing plate and a strap. The load-bearing plate is located below the water tank and is connected to the support rods by screws. The strap is attached to the side of the water tank, and both ends of the strap are connected to the two support rods respectively. The strap and the support rods are connected by metal buckles. A drive mechanism for rotating the support rods is located above the drone body.

[0007] Preferably, a U-shaped seat is provided between the support rod and the UAV body, the support rod and the U-shaped seat are rotatably connected, the U-shaped seat is fixed to the side of the UAV body, an extension rod is provided at the lower end of the support rod, and rollers are provided at both ends of the extension rod.

[0008] Preferably, the driving mechanism consists of an electric telescopic rod and a transmission rod. The electric telescopic rod is fixed to the top of the UAV body, one end of the transmission rod is connected to the piston rod inside the electric telescopic rod, and the other end of the transmission rod is rotatably connected to the upper end of the support rod.

[0009] Preferably, the drone body is provided with a protective shell, the electric telescopic rod is located inside the protective shell, and the transmission rod passes through the protective shell.

[0010] Preferably, when the water tank is fixed on top of the load-bearing plate, a gap is left between the top of the water tank and the drone body.

[0011] Preferably, a propeller is provided on the side of the drone body, and a nozzle is provided below the propeller. The water tank and the nozzle are connected by a water pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention involves a drone carrying a water tank that lands above a mobile jack. The straps are then disconnected from the support rods. An electric telescopic rod pushes two support rods outwards until the two load-bearing plates are removed from under the water tank, allowing the tank to descend onto the mobile jack. Personnel then place the fully loaded water tank onto the mobile jack and push it back directly under the drone. Finally, the two support rods rotate inwards until the load-bearing plates return to their original position under the water tank. The straps are then reconnected to the support rods, allowing for the resumption of environmental dust suppression operations. This method improves the efficiency of assembling and disassembling the water tank and drone, reduces labor intensity, and increases operational efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 In this utility model, a low-altitude operation drone includes a drone body 1, an electric telescopic rod 6 is provided on the top of the drone body 1, water is located inside a water tank 7 located below the drone body 1, support rods 3 and straps 5 are provided on the sides of the water tank 7, and a load-bearing plate 4 is provided below the water tank 7.

[0019] In this embodiment: Please refer to Figures 1-3 In this embodiment of the utility model, a low-altitude operation drone has a support rod 3 connected to the drone body 1 via a U-shaped seat 301. The support rod 3 is axially connected to the U-shaped seat 301, and the U-shaped seat 301 is fixed to the side of the drone body 1. An extension rod 302 is provided at the lower end of the support rod 3, and rollers 303 are provided at both ends of the extension rod 302.

[0020] The load-bearing plate 4 is located below the water tank 7. The load-bearing plate 4 is connected to the support rod 3 by screws. The strap 5 is attached to the side of the water tank 7. The two ends of the strap 5 are connected to the two support rods 3 respectively. The strap 5 and the support rod 3 are connected by metal buckles.

[0021] The electric telescopic rod 6 is located inside the protective shell 2, which is fixed on top of the UAV body 1. A transmission rod 601 is provided on one side of the protective shell 2. One end of the transmission rod 601 is connected to the piston rod inside the electric telescopic rod 6, and the other end of the transmission rod 601 is connected to the upper shaft of the support rod 3. After the electric telescopic rod 6 is started, the transmission rod 601 pushes the support rod 3 to rotate around the U-shaped seat 301.

[0022] A propeller 101 is installed on the side of the drone body 1, and a nozzle 102 is installed below the propeller 101. The water tank 7 is connected to the nozzle 102 through a water pipe. When the drone body 1 carries the water tank 7 over the construction site, the water is sprayed onto the ground through the nozzle 102.

[0023] First, a mobile, retractable platform (in this embodiment, a mobile jack) is set up on the ground. After the water in the water tank 7 is sprayed out, the drone body 1, carrying the empty water tank 7, lands above the mobile jack and disconnects the straps 5 from the support rods 3. The electric telescopic rod 6 then pushes the two support rods 3 outwards simultaneously until the two load-bearing plates 4 leave the bottom of the water tank 7, causing the water tank 7 to descend onto the mobile jack. Then, personnel place the fully loaded water tank 7 on the mobile jack and push the mobile jack back directly under the drone body 1. Finally, the two support rods 3 rotate inwards simultaneously until the two load-bearing plates 4 return to the bottom of the water tank 7, and the straps 5 are reconnected to the support rods 3. The environmental dust suppression operation can then be carried out again, improving the efficiency of disassembling and assembling the water tank 7 and the drone body 1, reducing the labor intensity of personnel, and improving work efficiency.

[0024] After the drone body 1 lands, the rollers 303 are in contact with the ground. When the two support rods 3 rotate outward at the same time, the two rollers 303 move away from each other and the drone body 1 moves downward. When the two support rods 3 rotate inward at the same time, the two rollers 303 move closer to each other and the drone body 1 moves upward.

[0025] In addition, when the water tank 7 is fixed to the load-bearing plate 4 by the straps 5, there is a gap of at least ten centimeters between the top of the water tank 7 and the drone body 1. The gap is used to prevent the water tank 7 from interfering with the normal movement of the load-bearing plate 4 when the support rod 3 drives the load-bearing plate 4 to rotate.

[0026] The working principle of this utility model is as follows: After the water in the water tank 7 is sprayed out, the drone body 1 lands carrying the empty water tank 7, and then the straps 5 are released from the support rods 3. Then, the two support rods 3 rotate outward at the same time, and the two load-bearing plates 4 move away from under the water tank 7. The water tank 7 falls onto the mobile jack directly below. Then, the fully loaded water tank 7 is moved to directly under the drone body 1 by the mobile jack. Finally, when the two support rods 3 rotate inward at the same time, the two load-bearing plates 4 move to under the water tank 7. Then, the straps 5 are reconnected to the support rods 3, thus completing the replacement of the water tank 7. The environmental dust suppression operation can then be carried out again, which improves the disassembly and assembly efficiency of the water tank 7 and the drone body 1 and reduces the labor intensity of personnel.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
