Description

Technical Field

[0001] This utility model relates to the field of agricultural drone technology, specifically to an electronically regulated water-cooled heat dissipation system for agricultural drones. Background Technology

[0002] Agricultural drones, also known as unmanned aerial vehicles (UAVs), are unmanned aircraft used for the protection of agricultural and forestry plants. These UAVs consist of three parts: a flight platform, navigation and flight control system, and spraying mechanism. They are operated via ground remote control or navigation and flight control to perform spraying operations, including spraying pesticides, seeds, and powders. With the rapid development of drone technology, agricultural drones are no longer limited to spraying pesticides; they can also perform various tasks such as fertilizing, sowing seeds, and spreading feed, meeting the diverse needs of farmers and improving production efficiency. Many drone companies are actively exploring agricultural solutions based on drone technology, jointly promoting the development, innovation, and progress of global agriculture.

[0003] For example, patent document CN 207141401 U discloses an electrically adjustable water-cooled heat dissipation system for an agricultural protection drone, including an electrically adjustable heat dissipation device and a circulating cooling device. The electrically adjustable heat dissipation device includes a heat sink, a heat sink, a sealing ring, and a cover plate. The heat sink includes a base plate, an electrically adjustable mounting part fixed on one side of the base plate, and a heat dissipation part fixed on the other side of the base plate. The base plate of the heat sink is sealed to the cover plate through the sealing ring. A water inlet and a water outlet are provided on the cover plate. The circulating cooling device includes a medicine tank for containing medicine liquid, a water pump, a nozzle, and pipelines. The water inlet is connected to the water pump and the medicine tank through the pipelines, and the water outlet is connected to the nozzles through the pipelines.

[0004] However, when this structure is used for the electronically controlled water cooling of agricultural drones, due to its own structural limitations, the pesticide cannot make sufficient contact with the cooling structure, affecting the overall heat dissipation effect of the equipment. At the same time, the equipment cannot conduct sufficient airflow over a larger area, which cannot meet the daily use needs. Therefore, it is urgent to design an electronically controlled water cooling system for agricultural drones to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electronically controlled water-cooled heat dissipation system for agricultural drones, in order to solve the problems mentioned in the background art. When using the existing structure for electronically controlled water-cooled heat dissipation of agricultural drones, due to the limitations of its own structure, the agent cannot make sufficient heat dissipation contact with the heat dissipation structure, which affects the overall heat dissipation effect of the equipment. At the same time, the equipment cannot conduct sufficient airflow over a larger area, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronically regulated water-cooled heat dissipation system for plant protection drones, including a heat dissipation frame, a mounting seat fixedly connected to the surface of the heat dissipation frame, and a flow-diverting side frame fixedly connected to both sides of the heat dissipation frame. A feed pipe is provided on one side of the heat dissipation frame through the flow-diverting side frame, and a discharge pipe is provided on the other side of the heat dissipation frame through the flow-diverting side frame.

[0007] The material box is fixedly connected to the bottom of the heat dissipation rack, the ventilation rack is fixedly connected to the front of the material box, and the air distribution rack is fixedly connected to the top of the ventilation rack.

[0008] Preferably, the air distribution frame has an air distribution groove inside, and the inner wall of the air distribution groove is uniformly provided with air distribution arc plates.

[0009] Preferably, the front of the ventilation frame is provided with an air converging guide groove.

[0010] Preferably, an arc-shaped pipe groove is provided on one side of the diversion side frame, and a diversion grid is provided on the inner wall of the arc-shaped pipe groove.

[0011] Preferably, a heat-conducting pad is provided at the center of the surface of the adhesive seat, and a sealing ring is provided at the edge of the surface of the adhesive seat.

[0012] Preferably, the heat sink is provided with a heat dissipation and flow plate inside, and a liquid pump is provided at the center of the feed pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This water-cooling system for the electronic speed controller (ESC) of an agricultural drone, through its heat dissipation frame, mounting base, distribution side frame, inlet pipe, outlet pipe, material box, arc-shaped pipe groove, distribution grid, thermal pad, sealing ring, heat dissipation flow plate, and liquid pump, enables the equipment to perform more efficient water-cooling operations for the ESC of the agricultural drone. In actual use, the operator first installs the mounting base on the surface of the heat dissipation frame onto the bottom of the ESC of the agricultural drone. The thermal pad and sealing ring on the surface of the mounting base are then fitted to the heat-generating locations, and the entire system, including the material box, is installed at the bottom of the agricultural drone. The pesticide solution is filled inside the tank. Normally, ventilation and heat dissipation are achieved through the heat dissipation plate inside the heat dissipation frame. When the pump is started, the pesticide solution is drawn out from the tank through the inlet pipe. The solution is then guided through the diversion grid of the arc-shaped pipe groove inside the diversion side frame, and then enters the heat dissipation plate inside the heat dissipation frame for further diversion. Finally, it is discharged from the diversion side frame and the outlet pipe on the other side of the heat dissipation frame. This achieves efficient simultaneous air cooling and water cooling of the agricultural drone, greatly improving the overall heat dissipation effect of the equipment and demonstrating the practicality of the equipment design.

[0015] This electronically regulated water-cooled heat dissipation system for agricultural drones further enhances the overall performance of the equipment through its heat dissipation frame, material box, ventilation frame, air distribution frame, air distribution duct, air distribution arc plate, and air converging guide duct. During daily use, the ventilation frame can be installed on the front of the material box. When the agricultural drone takes off, the air converging guide duct on the front of the ventilation frame gathers airflow, concentrating it at the air distribution frame at the top. Then, the air distribution duct inside the air distribution frame is divided by the air distribution arc plate, and the airflow is matched with the heat dissipation flow plate inside the heat dissipation frame, allowing for more efficient airflow within the frame and demonstrating the comprehensive nature of the equipment.

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.

[0022] Please see Figure 1-4 One embodiment provided by this utility model:

[0023] A plant protection drone's electrically adjustable water-cooled heat dissipation system includes a heat dissipation frame 1, a mounting seat 2 fixedly connected to the surface of the heat dissipation frame 1, and diversion side frames 3 fixedly connected to both sides of the heat dissipation frame 1. A feed pipe 4 is provided on one side of the heat dissipation frame 1 through the diversion side frame 3, and a discharge pipe 5 is provided on the other side of the heat dissipation frame 1 through the diversion side frame 3. An arc-shaped pipe groove 12 is opened on one side of the diversion side frame 3, and a diversion grid 13 is provided on the inner wall of the arc-shaped pipe groove 12. A heat-conducting pad 14 is provided at the center of the surface of the mounting seat 2, and a sealing ring 15 is provided at the edge of the surface of the mounting seat 2. A heat dissipation flow plate 16 is provided inside the heat dissipation frame 1, and a liquid pump 17 is provided at the center of the inside of the feed pipe 4.

[0024] The bottom of the material box 6 and the heat dissipation rack 1 are fixedly connected to the material box 6. The front of the material box 6 is fixedly connected to the ventilation rack 7. The top of the ventilation rack 7 is fixedly connected to the air distribution rack 8. The air distribution rack 8 has an air distribution groove 9 inside. The inner wall of the air distribution groove 9 is evenly provided with air distribution arc plates 10. The front of the ventilation rack 7 has an air gathering guide groove 11.

[0025] Working principle: During use, the user first installs the contact seat 2 on the surface of the heat sink 1 onto the bottom of the electronic control unit of the agricultural drone. The heat-conducting pad 14 and sealing ring 15 on the surface of the contact seat 2 are properly fitted to the heat-generating location. The entire unit, including the feed hopper 6, is then installed at the bottom of the agricultural drone. The feed hopper 6 is filled with pesticide. Normally, ventilation and heat dissipation are achieved through the heat dissipation plate 16 inside the heat sink 1. At this time, starting the pump 17 draws the pesticide from the feed hopper 6 through the inlet pipe 4. The pesticide then flows along the diversion grid 13 of the arc-shaped channel 12 inside the diversion side frame 3, and then enters the heat dissipation plate 16 inside the heat sink 1 for diversion. Finally, the pesticide flows out from the other side of the heat sink 1. The air is discharged through the diversion side frame 3 and the discharge pipe 5, thereby achieving efficient simultaneous air cooling and water cooling of the plant protection drone, greatly improving the overall heat dissipation effect of the equipment. In daily use, the ventilation frame 7 can be installed on the front of the material box 6. When the plant protection drone takes off, the airflow can be gathered at the air-gathering guide slot 11 on the front of the ventilation frame 7 and concentrated at the air-diverting frame 8 at the top of the ventilation frame 7. Then, the internal air-diverting slot 9 of the air-diverting frame 8 is divided by the air-diverting arc plate 10, and is matched with the heat dissipation flow plate 16 inside the heat dissipation frame 1, so that the heat dissipation airflow is more fully guided inside the heat dissipation frame 1. The above is the entire working principle of this utility model.
