Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a long-endurance inspection UAV for farmland construction. Background Technology

[0002] With the acceleration of agricultural modernization, farmland inspection, as a crucial link in the scientific management and yield improvement of crops, has created an increasingly urgent need for efficient and accurate monitoring methods. Drones, with their advantages of high flexibility, wide coverage, and rapid deployment, are gradually becoming an important tool for farmland inspection. Equipped with high-definition cameras, multispectral sensors, and other devices, drones can acquire key information in real time, such as farmland topography, crop growth status, and pest and disease conditions, providing data support for agricultural production decisions.

[0003] However, existing farmland inspection drones still have many problems in practical applications. On the one hand, during long-term flight, the internal electrical equipment of the drone, such as the power system and data processing module, will continuously generate a lot of heat. If the heat dissipation is not timely, it will lead to a decline in equipment performance or even failure, which will seriously affect the drone's endurance and operational stability. In addition, active cooling structures will occupy internal installation space and waste electrical energy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a long-endurance inspection drone for farmland construction.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A long-endurance inspection drone for farmland construction includes:

[0007] The machine body integrates electrical equipment inside, and an inspection module is installed at its bottom.

[0008] Multiple side arms are evenly arranged along the circumference of the machine body;

[0009] An air inlet is located at one end of the side arm to receive air.

[0010] The exhaust duct is located inside the side arm, with one end connected to the air inlet and the other end connected to the interior of the machine body;

[0011] The propeller is rotatably mounted on the top of one end of the side arm, and its rotational projection area covers the air inlet.

[0012] Each exhaust duct has its exhaust outlet facing a different surface of the electrical equipment. The downward airflow generated by the propeller enters the exhaust duct through the air inlet, forming a multi-directional heat dissipation airflow for the electrical equipment.

[0013] Preferably, it also includes an arc-shaped guide plate, which is located inside the air inlet and has its concave surface facing the extension direction of the exhaust duct.

[0014] Preferably, the ratio of the radius of curvature of the arc-shaped guide plate to the width of the corresponding side arm is 1:0.8-1.2.

[0015] Preferably, the inner wall of the exhaust duct is provided with multiple guide ribs, which are spirally distributed along the airflow direction.

[0016] Preferably, the angle between the propeller axis and the center line of the air inlet is 15°-30°.

[0017] Preferably, the exhaust duct is provided with a water collection tank below the middle of the side arm, and a pressure valve is installed at the bottom of the water collection tank.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] Excellent heat dissipation: The downward airflow generated by the propeller rotation enters the exhaust channel through the air inlet. The exhaust outlets of each exhaust channel face different surfaces of the electrical equipment, forming a multi-directional heat dissipation airflow, which effectively reduces the operating temperature of the electrical equipment and ensures stable operation of the equipment for a long time.

[0020] The spiral-shaped guide ribs on the inner wall of the exhaust duct optimize the airflow path and enhance the heat dissipation effect;

[0021] The propeller axis forms an angle of 15°-30° with the center line of the air inlet, ensuring that the downward airflow smoothly covers the air inlet and enters efficiently, providing a sufficient air source for heat dissipation.

[0022] The radius of curvature of the arc-shaped guide plate inside the air inlet is 1:0.8-1.2, which can effectively guide and gather the airflow entering the air inlet, improve the efficiency of airflow entering the exhaust channel, and further enhance the heat dissipation effect.

[0030] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0031] Example

[0032] like Figure 1-5 As shown, a long-endurance inspection drone for farmland construction includes:

[0033] Airframe 1: Internally integrated are the electrical devices, which are crucial for the drone to achieve flight, data collection, and transmission functions. At the bottom of Airframe 1 is an inspection module, which can be equipped with various detection devices such as high-definition cameras and multispectral sensors for real-time monitoring and data collection of farmland topography, crop growth, and pest and disease conditions.

[0034] Side arms 2: Multiple side arms 2 are evenly arranged around the body 1, which not only support the propeller 3, but also create a unique heat dissipation airflow channel.

[0035] Air inlet 21: Located at one end of the side arm 2, it is used to receive the downward airflow generated by the rotation of the propeller 3, providing an air source for the subsequent heat dissipation process.

[0036] Exhaust duct 22: Located inside the side arm 2, one end connects to the air inlet 21, and the other end connects to the interior of the main body 1. The exhaust vents of each exhaust duct 22 are positioned facing different surfaces of the electrical equipment, allowing the downward airflow generated by the propeller 3 to enter the exhaust duct 22 through the air inlet 21, forming a multi-directional cooling airflow for the electrical equipment. This effectively reduces the operating temperature of the equipment and ensures stable operation over extended periods. Furthermore, the inner wall of the exhaust duct 22 is equipped with multiple guide ribs, which are spirally distributed along the airflow direction to further optimize the airflow path and enhance heat dissipation.

[0037] Propeller 3: Rotatably mounted on the top of one end of side arm 2, its rotational projection area covers air inlet 21, and the downward airflow generated during rotation drives the formation of cooling airflow. The angle between the axis of propeller 3 and the center line of air inlet 21 is 15°-30°. This angle design helps to guide airflow more smoothly into air inlet 21 and exhaust duct 22.

[0038] Arc-shaped guide plate 23: Located inside the air inlet 21, with its concave surface facing the extension direction of the exhaust channel 22, and its radius of curvature ratio to the width of the corresponding side arm 2 is 1:0.8-1.2. This design can effectively guide and converge the airflow entering the air inlet 21, improve the efficiency of airflow entering the exhaust channel 22, and enhance the heat dissipation effect.

[0039] Water collection tank and pressure valve: A water collection tank is located below the middle of the side arm 2 in the exhaust duct 22 to collect moisture condensed during airflow or rainwater that may accidentally enter. A pressure valve is installed at the bottom of the water collection tank. When the water in the collection tank reaches a certain amount and the pressure exerted on the pressure valve exceeds a set value, the pressure valve will automatically open to discharge the water and prevent it from damaging the internal equipment of the drone.

[0040] In terms of flight, propeller 3 is rotatably mounted on the top of one end of side arm 2. When the drone is started, propeller 3 begins to rotate at high speed, generating lift through interaction with the air, enabling the drone to take off stably and fly in the air. The axis of propeller 3 forms an angle of 15°-30° with the center line of air inlet 21. This special angle design not only ensures that the downward airflow generated by propeller 3 can smoothly cover air inlet 21, but also guides the airflow to enter air inlet 21 more efficiently, providing sufficient air source for the subsequent heat dissipation process.

[0041] The downward airflow generated by the rotation of propeller 3 enters the exhaust duct 22 inside the side arm 2 through the air inlet 21. The arc-shaped guide plate 23 inside the air inlet 21 has its concave surface facing the extension direction of the exhaust duct 22, and its radius of curvature is in the ratio of 1:0.8-1.2 to the width of the corresponding side arm 2. This design effectively guides and converges the airflow entering the air inlet 21, improving the efficiency of airflow entering the exhaust duct 22. The spiral-shaped guide ribs on the inner wall of the exhaust duct 22 further optimize the airflow path, allowing the airflow to flow more smoothly within the duct. The exhaust vents of each exhaust duct 22 face different surfaces of the electrical equipment inside the fuselage 1. After the airflow exits from the exhaust vents, it forms a multi-directional cooling airflow for the electrical equipment, quickly removing the heat generated during operation and ensuring stable operation of the equipment at a suitable temperature, thus guaranteeing long-endurance operation of the UAV.

[0042] In terms of waterproofing, the water collection tank and pressure valve located in the lower middle part of the side arm 22 of the exhaust duct 22 play an important role. During airflow transmission, moisture in the air may condense into water droplets, or rainwater may enter the exhaust duct 22 in rainy weather. The water collection tank can collect this moisture in a timely manner. When the water in the collection tank reaches a certain amount and the pressure generated on the pressure valve exceeds the set value, the pressure valve automatically opens, expelling the accumulated water from the outside of the drone. This effectively prevents water accumulation from damaging the internal equipment of the drone and improves the reliability of the drone in complex environments.

[0043] In inspection operations, the inspection module installed at the bottom of the drone plays a crucial role. This module can be equipped with various detection devices such as high-definition cameras and multispectral sensors. During the drone's flight, these devices can perform a comprehensive scan of the farmland, collecting data in real time on the farmland's topography, crop growth status, and pest and disease conditions. The collected data is processed and transmitted through the integrated electrical equipment inside the drone, thereby achieving high-precision, comprehensive inspection of the farmland and providing detailed data support for farmland construction and management.

[0044] I. Principles of Intelligent Identification of Construction Quality

[0045] Equipped with high-definition imaging equipment, drones conduct comprehensive image acquisition of farmland construction areas during flight inspections. The acquired images are transmitted in real-time to the drone's built-in or cloud-based processing system, where AI algorithms perform in-depth analysis. For slope error identification, the AI ​​algorithm extracts terrain feature points from the images, combines them with preset slope standard data, and uses geometric calculations and pattern recognition technology to accurately calculate the deviation between the actual slope and the standard slope. In terms of ridge curvature detection, the AI ​​algorithm extracts the contours and fits curves to the ridge edges, comparing them with standard curve models to determine whether the ridge curvature meets construction requirements. Leveraging the powerful analytical capabilities of AI algorithms, "one inspection, multiple checks" is achieved. It can not only simultaneously detect multiple construction quality issues but also categorize and organize information such as problem type, location, and severity, providing precise data support for construction quality rectification and contributing to refined project management.

[0046] II. Principles of Quantitative Management of Construction Progress

[0047] Drones regularly conduct surveying flights over the project area according to a pre-set inspection plan. During the flight, they collect a large amount of spatial data using an onboard high-precision positioning system and multiple sensors (such as LiDAR and oblique photography cameras). This data is processed by specialized software to construct a realistic 3D model and high-definition aerial images of the project. The 3D model presents the current construction status in a three-dimensional, visualized form. By comparing and analyzing it with the design model, the proportion of completed work to the total work can be accurately calculated, thereby quantifying the construction progress. Simultaneously, the system continuously tracks the dynamic changes of the 3D model, enabling full lifecycle management of key projects and timely detection and warnings of delays. After project completion, the accumulated complete data assets are integrated into a dedicated database. This data not only provides a reference for subsequent project construction but can also be applied to scenarios such as refined urban governance and emergency fire fighting, realizing the diversified value transformation of data assets and empowering social management.

[0048] III. Principles of Human Resource Cost Optimization

[0049] Traditional farmland construction inspections rely heavily on manual labor, requiring dozens of people and several days to complete a comprehensive inspection. This method suffers from low efficiency, strong subjectivity, and a high risk of omissions. Intelligent inspection drones, with their automated inspection capabilities, can replace manual inspections. Drones can autonomously plan inspection routes, quickly cover large construction areas, and are not limited by terrain complexity, completing high-quality inspections in a short time. For areas that are difficult to reach or pose safety risks, such as steep slopes and swampy areas, drones can conduct inspections safely and efficiently, preventing construction workers from entering dangerous areas and ensuring their safety. By reducing manpower input and lowering labor costs, while simultaneously improving inspection efficiency and quality, drones alleviate the workload of frontline staff.

[0050] IV. Unmanned Airport and System Collaboration Principles

[0051] As the "smart hub" of drones, unmanned aerial vehicle (UAV) airports operate collaboratively with intelligent inspection drones and related systems to meet the needs of low-altitude economic development. UAV airports are equipped with automated charging and maintenance equipment and intelligent dispatch systems, enabling autonomous charging, maintenance, and task allocation for drones. Before a mission, the system intelligently plans the drone inspection route and flight parameters based on factors such as the characteristics of the construction area and weather conditions. During the mission, the system monitors the drone's status and data transmission in real time to ensure smooth inspection. After the mission, the drone automatically returns to the UAV airport to complete data transmission and equipment maintenance. The construction of UAV airports and systems not only achieves automated and intelligent management of drone inspections but also aligns with policy responses, accelerates the cultivation of new productive forces, and promotes the transformation and upgrading of construction management from traditional models to intelligent and digital approaches.

[0052] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
