Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, and in particular to a multi-rotor water mist spraying UAV. Background Technology
[0002] Water mist spraying is crucial in modern agriculture, landscaping maintenance, environmental disinfection, and some industrial dust control applications. Traditional methods rely heavily on manual operation using handheld spray guns or large spraying equipment. Manual spraying is labor-intensive and inefficient, and significantly increases labor and time costs when dealing with large areas. Furthermore, manual operation makes it difficult to guarantee the uniformity and accuracy of the spray. While large spraying equipment can improve efficiency, it suffers from poor flexibility, making it difficult to operate in complex terrain or confined spaces, and its purchase and maintenance costs are high.
[0003] The rise of drone technology has provided new solutions to the aforementioned problems. However, ordinary drones have many shortcomings when performing water mist spraying tasks. For example, during takeoff and landing, the bottom of the drone is prone to collisions with the ground or other obstacles, causing equipment damage and affecting the continuity and stability of the operation. In addition, the traditional method of fixing spray guns is not flexible enough, making it difficult to accurately adjust the spraying angle according to different operational needs and terrain conditions, thus limiting the coverage and spraying effect of the water mist.
[0004] To overcome these problems and achieve efficient, flexible, and precise water mist spraying operations, it is particularly necessary to develop a specialized multi-rotor water mist spraying drone. Utility Model Content
[0005] To address some of the problems existing in the prior art, this utility model provides a multi-rotor water mist spraying drone. By equipping it with a spraying angle adjustment structure and a spray gun fixing structure, this utility model enables operators to flexibly adjust the spraying angle and position according to the actual working conditions, thereby improving the quality and efficiency of water mist spraying and meeting the diverse needs of different fields for water mist spraying operations.
[0006] To achieve the above objectives, this utility model provides a multi-rotor water mist spraying drone, comprising a spraying drone body, the spraying drone body including a main body, powered rotors installed around the main body, a fuselage connecting rod between the main body and the powered rotors, fixed support chassis on both sides of the bottom of the main body, an anti-ground contact structure at the center of the bottom of the main body, and a spraying angle adjustment structure on one side of the bottom of the main body, the spraying angle adjustment structure cooperating with a spray gun fixing structure.
[0007] As a further improvement of this utility model, in order to enhance the strength and stability of the structure, effectively protect the important components at the bottom of the main body, and enable the anti-ground contact structure to play a better role without affecting the spray angle adjustment function, thus ensuring the safety of the UAV under various working conditions, the anti-ground contact structure includes an anti-ground contact fixing plate set at the bottom of the main body. The anti-ground contact fixing plate is set between the fixed support chassis on both sides of the bottom of the main body. Anti-ground contact reinforcing ribs are respectively set on both sides of the anti-ground contact fixing plate. Anti-ground contact base plates are installed on the anti-ground contact reinforcing ribs on both sides. Anti-ground contact side plates are set between the anti-ground contact reinforcing ribs. The anti-ground contact fixing plate is configured in conjunction with the spray angle adjustment structure.
[0008] As a further improvement of this utility model, in order to easily achieve adjustment of the spray gun in multiple directions and angles, meet the requirements of water mist spraying range and direction in different scenarios, and improve the adaptability of the UAV to complex working environments, the spraying angle adjustment structure includes a joint connecting block. The joint connecting block is fixed on the anti-grounding fixing plate. The joint connecting block is equipped with a first joint and a second joint. The first joint is connected to the joint connecting block by a pin, and the second joint is connected to the first joint by a pin.
[0009] As a further improvement of this utility model, in order to facilitate the fixing and installation of the hose, and to make the installation and disassembly of the hose fixing bracket more convenient, so as to facilitate the replacement or maintenance of the hose when needed, the end of the second joint is U-shaped. The end of the second joint is fitted with a first hose fixing bracket and a second hose fixing bracket. The first hose fixing bracket and the second hose fixing bracket are fixed together by bolts. The first hose fixing bracket is provided with a protrusion on the side near the second joint. The protrusion is fitted with the U-shaped structure at the end of the second joint and is provided with a first quick-release pin.
[0010] As a further improvement of this utility model, in order to provide an initial fixed position for the spray gun, ensure a reliable connection between the entire fixing system and the main body, ensure the stability of the spray gun and related pipes during flight, and prevent the spraying effect from being affected by shaking, the spray gun fixing structure includes a spray gun fixing bracket set on the other side of the main body, the spray gun fixing bracket is equipped with a front fixing bracket, the other end of the front fixing bracket is fixed to the main body, and a first rigid pipe fixing bracket is installed below the front fixing bracket.
[0011] As a further improvement of this utility model, in order to achieve quick connection and disassembly between rigid tube fixing brackets, facilitate the assembly and maintenance of equipment, and enable quick disassembly and reinstallation, the first rigid tube fixing bracket is provided with a first docking hole, and the first rigid tube fixing bracket is cooperated with a second rigid tube fixing bracket, the top of the second rigid tube fixing bracket is provided with a second docking hole, the first docking hole and the second docking hole are cooperated with each other, and a second quick release pin is provided.
[0012] As a further improvement of this utility model, in order to further enhance the stability and flexibility of the rigid pipe fixing system, make the connection and disassembly between the second rigid pipe fixing bracket and the third rigid pipe fixing bracket more convenient, and ensure the firmness of the connection between the third rigid pipe fixing bracket and the fourth rigid pipe fixing bracket, the second rigid pipe fixing bracket is provided with a third rigid pipe fixing bracket. The second rigid pipe fixing bracket and the third rigid pipe fixing bracket are provided with mounting holes and a third quick-release pin. The third rigid pipe fixing bracket is provided with a fourth rigid pipe fixing bracket. The fourth rigid pipe fixing bracket and the third rigid pipe fixing bracket are fixedly connected by bolts.
[0013] When this utility model is in operation, during the spraying preparation stage, the anti-grounding structure in the center of the bottom of the main body comes into play. The anti-grounding fixing plate is located between the fixed support chassis on both sides. The anti-grounding reinforcing ribs on both sides, the anti-grounding bottom plate, and the anti-grounding side plate together form a protective system to prevent the water pipe from contacting the ground and causing the drone to overturn.
[0014] Next, the spray angle is adjusted. The joint connecting block of the spray angle adjustment structure is fixed to the anti-ground fixing plate. The first joint is connected to the joint connecting block by a pin, and the second joint is connected to the first joint by a pin. According to the operation requirements, the operator can flexibly adjust the angle of the second joint by controlling the rotation of the joint, thereby changing the spray direction of the spray gun.
[0015] After adjusting the spray gun angle, the spray gun and pipe are fixed. The U-shaped structure at the end of the second joint mates with the protrusion of the first hose fixing bracket and is secured with the first quick-release pin. Simultaneously, the first and second hose fixing brackets are secured to the hose with bolts. On the other side of the main body, the spray gun is fixed to the spray gun fixing bracket, which mates with the front fixing bracket. The front fixing bracket is fixed to the main body. The lower first rigid pipe fixing bracket is connected to the second rigid pipe fixing bracket via the first and second mating holes and the second quick-release pin. Subsequently, the second rigid pipe fixing bracket is connected to the third rigid pipe fixing bracket via mounting holes and the third quick-release pin. The third rigid pipe fixing bracket is then secured to the fourth rigid pipe fixing bracket with bolts, ensuring the stability of the entire spraying system.
[0016] Finally, the spray gun is activated, and water mist is sprayed out through the pipes, allowing the drone to fly along the preset route. The main body serves as the core, with the surrounding powered rotors securely connected via fuselage connecting rods. The power system is then activated, and the powered rotors rotate at high speed, providing lift for the drone to take off smoothly. This completes the large-area water mist spraying operation. After the operation, the drone lands smoothly, completing a full workflow.
[0017] The beneficial effects of this utility model are as follows: In terms of anti-ground contact design, the anti-ground contact fixing plate, reinforcing ribs, bottom plate and side plate in the anti-ground contact structure work together to effectively prevent the bottom of the main body of the drone from contacting the ground when landing or operating at low altitude, preventing equipment damage caused by ground contact, especially protecting the spray angle adjustment structure that works with it, extending the service life of the drone and reducing maintenance costs.
[0018] In the design of the spray angle adjustment structure, the joint connecting block, the first joint, and the second joint are connected by a pin, allowing the spray gun angle to be flexibly adjusted to meet the spraying needs in different scenarios and improve the accuracy and coverage of the spraying operation. At the same time, the cooperation between the end of the U-shaped second joint and the hose fixing bracket, as well as the setting of the quick-release pin, facilitates the installation and disassembly of the hose, improving work efficiency.
[0019] In the design of the spray gun fixing structure, multiple rigid tube fixing brackets are connected and fixed by quick-release pins and bolts, which not only ensures the stability of the spray gun during flight but also enables quick assembly and disassembly. This allows for rapid operation when the spray gun needs to be replaced or maintained, reducing downtime and improving the efficiency of the drone. Attached Figure Description
