Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a multi-rotor unmanned aerial vehicle with multiple functions. Background Art

[0002] With the rapid development of modern agricultural technology, intelligent equipment such as drones are being used more and more widely in agricultural production, especially in pesticide spraying. Drones have gradually replaced traditional spraying methods with their advantages of high efficiency, precision and environmental protection. Drone spraying of pesticides can not only improve work efficiency and reduce labor costs, but also reduce pollution to the environment and human body. It is an important direction for the sustainable development of modern agriculture.

[0003] When traditional drones are performing pesticide spraying operations, due to the heavy load, the batteries will generate more heat during operation. When the weather is hot, the performance may be reduced due to overheating, and even cause safety hazards. In addition, the drone camera is often exposed when not in use and lacks necessary protection measures. In addition, when landing, the impact force between the fuselage and the ground is large, which may cause damage to the drone structure.

[0013] As a further improvement of the present invention, sensors are fixedly connected to both sides of the upper surface of the body.

[0014] Beneficial effects of the present invention:

[0015] By setting up a fixing component, when in use, the storage box containing pesticides is placed between the first limit plate and the movable plate on the support plate, and the adjusting bolt is turned to fix the storage box, so that the drone can fix and transport items of different sizes and weights. The adjustment mechanism of the movable plate provides great flexibility, allowing the device to adapt to various transportation needs, thereby improving the practicality and versatility of the device.

[0016] By setting up the shooting components, when in use, the drone is equipped with multiple rotor structures to provide sufficient power, ensuring the stability and reliability of the flight. At the same time, the electric push rod is started until the camera moves out of the protective shell. The adjusting motor can drive the camera to change the angle inside the mounting base, thereby adjusting the field of view of the drone, so that the drone can obtain a wider field of view in real time during flight and operation, improving the accuracy and safety of the operation. At the same time, the protective shell can protect the camera when the device is not in use, avoiding damage to the camera during transportation and transfer, thereby increasing the safety of the device.

[0017] By setting up a cooling component, when the UAV flies over the farmland to operate, the battery provides power for multiple rotor structures and generates heat. The light water pump is started to use the pesticide in the storage box as a coolant, which is input into the cooling pipe through the pumping pipe and the water pipe to dissipate the heat of the battery. The device can not only effectively reduce the operating temperature of the battery and prevent performance degradation or damage caused by overheating, but also extend the service life of the battery and ensure that the battery can still work normally in a high temperature environment, thereby ensuring the continuous flight capability and operating efficiency of the UAV. At the same time, during the cooling process, the pesticide not only takes away the heat generated by the battery, but can also continue to be used in subsequent operations, realizing the recycling of resources.

[0018] By setting up a spraying component, when in use, the pesticide takes away the heat of the battery in the cooling tube and is sprayed out through the sprinkler pipe and nozzle. Its temperature will be reduced in the air, avoiding the risk of damage to agricultural products due to overheating of the pesticide, protecting the quality and yield of agricultural products. Using pesticide as a coolant avoids the environmental pollution and safety hazards that may be caused by traditional coolants.

[0019] By setting up a buffer component, when the drone lands on the ground, the base and the sleeve rod first contact the ground to generate impact force. The fixed rod and damping buffer inside the sleeve rod can effectively absorb and disperse these impact forces, reducing the risk of wear and damage to the internal parts of the drone, thereby improving the durability and service life of the drone.

[0020] In summary, the present invention has demonstrated various beneficial effects during use, such as flexibility and efficiency, precision and safety, efficient heat dissipation, resource recycling, protection of drone structure, improved durability, enhanced user experience and enhanced adaptability, etc., providing great convenience and benefits for agricultural operations and other fields of application.
