Description

Technical Field

[0001] This utility model relates to the field of plant protection operation equipment technology, and more specifically, to a plant protection drone operation support vehicle. Background Technology

[0002] With the acceleration of global agricultural modernization, traditional manual or ground-based mechanical plant protection operations have gradually revealed problems such as low efficiency, high cost, insufficient pesticide utilization, and labor shortages. Against this backdrop, agricultural drones have rapidly emerged due to their flexibility, efficiency, and precision spraying capabilities. Equipped with high-precision navigation systems (such as RTK positioning), multispectral sensors, and intelligent spraying devices, agricultural drones can achieve centimeter-level positioning and variable-rate spraying, significantly reducing pesticide waste (saving more than 30% compared to traditional methods) and avoiding over-spraying and under-spraying. The combination of their autonomous obstacle avoidance technology and cloud-based data management platforms further enhances operational safety in complex terrains and the ability to achieve large-scale farmland coverage. In recent years, breakthroughs in battery energy density, lightweight materials, and AI pest and disease recognition algorithms have driven the development of agricultural drones towards longer endurance and all-terrain adaptability, making them an indispensable core piece of equipment in the smart agriculture ecosystem.

[0003] To address pain points in modern agricultural mechanization and intelligent operations, such as lagging equipment maintenance, slow emergency response, and insufficient field support, the operational support vehicle has emerged as a mobile integrated service platform. This vehicle integrates a repair tool compartment, a quick tire repair device, a hybrid electric power supply system, and a remote diagnostic terminal. A real-time status monitoring module based on IoT technology can provide early warnings of abnormal operating conditions of agricultural machinery and dispatch the nearest support resources. Especially in hilly and mountainous areas with weak infrastructure, the support vehicle, equipped with a four-wheel drive chassis and water-crossing capability, significantly improves service accessibility.

[0004] Agricultural drones require continuous resupply of pesticides during operations. In long-distance missions, whether the drones fly independently or are transported between resupply stations and mission locations by a vehicle, efficiency is low, resulting in significant energy and time waste. Related technologies utilize dedicated support vehicles to carry pesticides, or to transport raw pesticides to the mission location for on-site preparation and resupply of drones, effectively improving operational efficiency. However, some pesticides have unique chemical properties that can easily become ineffective after prolonged storage, necessitating small-batch, frequent preparation or interventions to prevent inactivation. This requires substantial electrical power. Existing vehicle-mounted power generation systems typically utilize a combination of engine and generator, resulting in low energy conversion rates and high emissions. Therefore, effectively utilizing renewable energy sources, particularly solar energy, to power support vehicles and improve agricultural operation efficiency has become a pressing technical challenge.

[0044] Figure 1 This is a side view of the agricultural drone operation support vehicle provided in an exemplary embodiment of this utility model. Figure 2 This is a top view of the agricultural drone operation support vehicle provided in an exemplary embodiment of this utility model. Figure 3 yes Figure 1 A three-dimensional structural diagram of a solar power generation device in an exemplary embodiment is shown.

[0045] An exemplary embodiment of this utility model provides a support vehicle for agricultural drone operations, such as... Figures 1-3 As shown, the system includes a vehicle body 4, a cabin 5, a dispensing system 1, a solar power generation device 2, and an energy storage system 3. The cabin 5 is mounted on the vehicle body 4, and its top is suitable for parking agricultural drones. The dispensing system 1 is located inside the cabin 5 and is used to prepare and store target pesticides for use by the agricultural drone. The solar power generation device 2 is located on the top of the cabin 5 and includes a solar panel 21 and at least three connectors 22. The solar panel 21 is configured to convert solar energy into electrical energy under sunlight. The at least three connectors 22 are spaced apart circumferentially, with one end connected to the cabin 5 and the other end connected to the solar panel 21 via a spherical joint 23. The connectors 22 are configured to extend and retract axially to adjust the orientation of the solar panel 21 so that the ratio between the actual irradiance received by the solar panel and the standard irradiance is greater than a preset value. The energy storage system 3 is used to store electrical energy from the solar panel 21 and power the dispensing system 1.

[0046] In this implementation, the agricultural drone operation support vehicle consists of a vehicle body 4 and a cabin 5. The agricultural drone can be temporarily parked on top of the cabin 5 for easy resupply of target pesticides or short-distance relocation with the operation support vehicle. The operation support vehicle prepares and stores target pesticides through a pesticide preparation system 1 to reduce the time required for resupplying target pesticides to the agricultural drone, while ensuring the effectiveness of the target pesticides by preparing them on demand. A solar power generation device 2 generates solar power and stores it in an energy storage system 3 for use by the pesticide preparation system 1. The solar panel 21 is mounted on top of the cabin 5 through at least three connectors 22, and the connectors 22 and the solar panel 21 are connected by a spherical joint 23 to achieve orientation adjustment of the solar panel 21. Since the position of the sun changes in real time, the light intensity absorption rate is calculated by detecting the actual irradiance received by the solar panel 21 and calculating the ratio between the actual irradiance and the standard irradiance (e.g., 1000 W / m² of solar radiation power received per unit area under standard atmospheric conditions AM1.5 and 25°C). If the light intensity absorption rate is less than the preset value, the connection 22 is extended or retracted to change the length of the connector 22, thereby changing the orientation of the solar panel 21 until the light intensity absorption rate is greater than or equal to the preset value, thus achieving high-efficiency photoelectric conversion.

[0047] According to embodiments of this disclosure, the three connectors 22 are evenly spaced along the circumferential direction, i.e., the spherical joints 23 located at the first ends of the three connectors 22 form an equilateral triangle. At the same time, the center of its trajectory circle (i.e., the geometric center of the equilateral triangle) coincides with the center of the solar panel 21, so as to maximize the structural stability of the solar power generation device 2 and avoid excessive differences in force between different connectors 22.

[0048] In some optional embodiments, depending on the adjustment accuracy requirements of the solar panel 21, different numbers of connectors 22 can be designed. The more connectors 22 there are, the higher the adjustment accuracy of the solar panel 21 will be, but the complexity of the adjustment process will also increase accordingly. Therefore, the preferred number of connectors 22 is three to five.

[0049] Figure 4 yes Figure 1 A schematic diagram of the solar power generation device from another angle in the exemplary embodiment shown.

[0050] According to embodiments of this disclosure, such as Figure 3 and Figure 4 As shown, the connector 22 includes a push rod 221 and a sleeve 222. One end of the push rod 221 is connected to the solar panel 21 through a spherical joint 23, and the sleeve 222 is connected to the cabin 5 through the spherical joint 23. The other end of the push rod 221 is inserted into the sleeve 222.

[0051] In this embodiment, the push rod 221 is inserted into the sleeve 222 and can reciprocate in the sleeve 222 along the axial direction to realize the extension and retraction of the connector 22.

[0052] According to a further embodiment of the present disclosure, the push rod 221 is made of a permanent magnet, and a conductive coil is wound inside the sleeve 222, which is configured to drive the push rod 221 to move in the axial direction by electromagnetic induction in response to an energized state.

[0053] In this implementation, the push rod 221, made of a permanent magnet, serves as the mover, and the sleeve 222, wound with a conductive coil, serves as the stator. When the conductive coil is energized, it generates a magnetic field. The magnetic field interacts with the permanent magnet through magnetic force, causing the permanent magnet to move along the axial direction. At the same time, by adjusting the frequency and amplitude of the current in the conductive coil, the push rod 221 can move closer to or further away from the sleeve 222.

[0054] In some other embodiments, the connector 22 can also be a ball screw pair, a linear guide pair, or a rack and pinion pair, all of which can be driven by a motor, offering fast response and high precision. The connector 22 can also be a hydraulic / pneumatic cylinder, providing strong load-bearing capacity and good stability.

[0055] In one exemplary embodiment, the first end of the connector 22 is also connected to the cabin 5 via a spherical joint 23, and the extensions of the axes of any two connectors 22 intersect each other.

[0056] In this implementation, the connector 22 and the cabin 5 are also connected by a spherical joint 23, which can expand the range of motion of the solar panel 21. Accordingly, taking three connectors 22 as an example, the extension lines of the axes of the connectors 22 intersect each other, so that the three connectors 22 can provide stable support for the solar panel 21 to prevent the solar panel 21 from collapsing under the action of gravity.

[0057] In some other embodiments, the connector 22 and the cabin 5 can also be fixedly connected, that is, the sleeve 222 and the cabin 5 are fixedly connected. In this case, the axes of the multiple connectors 22 can be parallel to each other or intersect each other. Although the adjustment range of the solar panel 21 is slightly reduced, the stability of the entire solar power generation device 2 is higher and the adjustment process is simpler.

[0058] More specifically, taking the setting of three connectors 22 as an example, all three connectors 22 are connected to the solar panel 21 through spherical joints 23. One connector 22 is fixedly connected to the cabin 5, and the other two connectors 22 are connected to the cabin 5 through spherical joints 23.

[0059] In one exemplary embodiment, the solar energy detection device 2 further includes an irradiance sensor 24 mounted on the sun-facing surface of the solar panel 21, suitable for measuring the actual irradiance received by the solar panel 21.

[0060] In this implementation, the measured data is collected by the electronic control module of the work support vehicle, which further calculates the ratio of the remaining standard irradiance, compares it with the preset value, displays the comparison result, and at least gives an instruction of "adjustment required" or "no adjustment required". After receiving the adjustment instruction, the staff sends the instruction to the electronic control module through the control console or control panel. The electronic control module then sends an electrical signal to the solar power generation device 2 to drive the corresponding connector 22 to perform extension and retraction.

[0061] In one exemplary embodiment, the drug preparation system 1 includes a water storage tank 11, a mixing tank 12, and a finished product tank 13. The mixing tank 12 is equipped with a stirring paddle, suitable for stirring a mixture of the drug substance and water under the power supply of the energy storage system 3. The water storage tank 11 is connected to the mixing tank 12 via a pipe, suitable for supplying water to the mixing tank 12. The finished product tank 13 is connected to the mixing tank 12 via a pipe, suitable for storing the stirred target drug substance.

[0062] In this implementation, the agitator of the mixing tank 12 is driven by a motor, which is powered by the energy storage system 3. Liquid active pharmaceutical ingredients are delivered to the mixing tank 12 via a peristaltic pump and diluted with water. Solid active pharmaceutical ingredients are added through the dosing port on the mixing tank 12 and mixed with water. After mixing, the mixture is then transported to the finished product tank 13 for storage via a pump (including but not limited to a peristaltic pump). The temperature and humidity inside the finished product tank 13 can be adjusted according to the storage requirements of different target drugs, and the required electrical energy is also provided by the energy storage system 3.

[0063] According to an embodiment of this disclosure, the finished product tank 13 is configured to stir the target drug at preset intervals under the power supply of the energy storage system 3.

[0064] In this implementation, after the active ingredient is dissolved in water, precipitation may occur as the standing time increases. Alternatively, some solid granular active ingredients that are insoluble in water but require water for uniform application may precipitate after a short period of standing. Therefore, the finished product tank 13 is also equipped with a stirring paddle to stir the target drug once every preset time. For example, the stirring paddle is started for 1 minute every 1 hour to maintain the effectiveness of the drug.

[0065] In one exemplary embodiment, the energy storage system 3, the water storage tank 11, the mixing tank 12, and the finished product tank 13 are arranged sequentially within the cabin body along the length of the cabin body 5.

[0066] In this implementation, the arrangement simplifies pipe design and connection while minimizing the width of the compartment 5.

[0067] In one exemplary embodiment, the work support vehicle also includes a raw material storage section 6 and a finished product tank 13 arranged in the width direction within the cabin 5, suitable for storing raw materials.

[0068] In such an implementation, such as Figure 2 As shown, the diameters of the water storage tank 11, the mixing tank 12, and the finished product tank 13 are approximately equal, but slightly smaller than the width of the compartment 5. The water storage tank 11 and the mixing tank 12 are arranged close to the first side wall of the compartment 5, forming a receiving space with the second side wall for accommodating pipes and pumps. The finished product tank 13 is arranged close to the second side wall of the compartment 5, and the line connecting the finished product tank 13 and the mixing tank 12 forms an angle of 30°-45° with the length direction. The finished product tank 13, the mixing tank 12, and the first side wall form another receiving space for accommodating the raw material storage section 6. This improves the space utilization rate within the compartment 5 while minimizing the length of the compartment 5.

[0069] In one exemplary embodiment, the energy storage system 3 includes a battery 31 and a generator 32, the generator 32 being configured to convert mechanical energy into electrical energy under the drive of the engine of the vehicle body 4, and the battery 31 being adapted to store electrical energy from the generator 32 or the solar power generation device 2.

[0070] In this implementation, when the support vehicle is in motion, the engine is running, and the generator 32 converts the mechanical energy output by the engine into electrical energy to charge the battery 31. When the support vehicle is stationary, the engine stops running, as generating electricity solely from gasoline / diesel combustion is inefficient and wastes resources. At this time, after adjusting the orientation of the solar panel 21, the solar power generation device 2 generates electricity, prioritizing its use by the drug dispensing system 1, with any excess electricity charging the battery 31. When sunlight conditions are poor, the battery 31 can discharge its stored energy to power the drug dispensing system 1 or other devices on the support vehicle.

In particular, the features described in the various embodiments of this utility model can be combined and / or combined in various ways without departing from the spirit and teachings of this utility model.

Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination.
