Description

Technical Field

[0001] The utility model relates to the technical field of plant protection UAV equipment, in particular to a heat dissipation and waterproof structure of a plant protection UAV. Background Art

[0002] Plant protection drones are unmanned aircraft used for agricultural and forestry plant protection operations. They carry out spraying operations through ground remote control or navigation flight control. During the use of plant protection drones, their batteries need to be placed inside the battery compartment. The heat dissipation and waterproof structure inside the battery compartment assists in battery heat dissipation to avoid damage to the battery due to high temperature when the discharge current is large.

[0003] For example, the invention patent: "A heat dissipation and waterproof structure for plant protection drones" has a publication number of "CN110606210B". This patent uses the coordination between the wind wheel, eccentric spring, air inlet, vent and cavity No. 1. The rotating eccentric spring stirs and accelerates the air flow in cavity No. 1, accelerates the flow rate of cold air on the surface of the battery in the battery compartment, accelerates the reduction of the battery temperature inside the body, and prevents the battery temperature from being too high when the plant protection drone is working under heavy load. However, during the implementation of this patent, air directly enters the interior through the vent and directly contacts the drone battery. When the air humidity is high, it is easy to cause a battery short circuit, which can easily cause damage to the drone. Therefore, the present invention provides a heat dissipation and waterproof structure for a plant protection drone to solve the above problems. Utility Model Content

[0022] In this implementation:

[0023] Furthermore, a metal heat conducting plate A8 is installed on the inner side of the clamping plate 23, and a metal heat dissipation column 9 is evenly installed on one end of the metal heat conducting plate A8 close to the clamping plate 23. The metal heat dissipation columns 9 pass through the drone battery compartment 1 and extend to the inside of the heat dissipation slot B12, and heat dissipation fins A13 are evenly installed on the outer side of the metal heat dissipation columns 9. During use, the metal heat conducting plate A8 transfers the heat on the battery to the metal heat dissipation columns 9 and the heat dissipation fins A13, so that the metal heat dissipation columns 9 and the heat dissipation fins A13 transfer heat with the outside air through the heat dissipation slot B12, which can quickly dissipate heat, increase the heat dissipation area, and further improve the heat dissipation efficiency.

[0024] Furthermore, heat dissipation holes A2 are evenly arranged on the outside of the drone battery compartment 1, and the heat dissipation holes A2 are all connected to the heat dissipation groove B12, and dustproof nets A3 are installed inside the heat dissipation holes A2, so that external air can enter the heat dissipation groove B12 through the heat dissipation holes A2.

[0025] Furthermore, dustproof nets B5 are installed at both ends of the heat dissipation slot A4 to prevent external dust from entering the heat dissipation slot A4.

[0026] Furthermore, a spring 22 is installed on the top of the end of the splint 23 away from the metal heat-conducting plate A8, and the end of the spring 22 away from the splint 23 is connected to the drone battery compartment 1.

[0027] Furthermore, screw holes B20 are provided at both ends of the top of the sealed compartment cover 14, and mounting bolts 19 are threadedly installed inside the screw holes B20.

[0032] During use, the heat on the battery is transferred to the heat dissipation fins B17 through the metal heat conduction plate B18, so that the heat dissipation fins B17 transfer heat with the outside air through the heat dissipation slots A4, which can quickly dissipate the heat and prevent the battery from directly contacting the outside air, thereby ensuring the heat dissipation effect and effectively improving the sealing performance;

[0033] At the same time, the metal heat conducting plate A8 transfers the heat from the battery to the metal heat dissipating column 9 and the heat dissipating fin A13, so that the metal heat dissipating column 9 and the heat dissipating fin A13 transfer heat with the outside air through the heat dissipating groove B12, which can quickly dissipate the heat, increase the heat dissipation area, and further improve the heat dissipation efficiency.
