[0032] Specifically, when the battery charging box is subjected to the heat dissipation process, the rotating plate 6 needs to be rotated first, which will open the hollow box 9; then, the ice plate 10 is placed in the hollow box 9; the role of the hollow box 9 is to act as a medium for heat transfer and to conduct the heat inside the charging box; then, take the hollow box 9 and align the arc rod 3 with the fixed box 17; at the same time, the hollow box 9 is pressed down so that the sawtooth bar 16 and the gear 11 are meshed for transmission; this design enables the sawtooth bar 16 to drive the gear 11 to rotate, thereby improving the efficiency of heat dissipation; when the sawtooth bar 16 is pressed down to the bottom position, the limit plate 15 needs to be flipped; at the same time, the rotating shaft 14 is rotated , insert the limit plate 15 into the slot 12 and snap it into the teeth of the gear 11; the purpose of this step is to fix the position of the serrated bar 16 to ensure the stability of heat dissipation; next, install and fix the hollow box 9; when the charging box is in operation, the heat will be transferred to the ice plate 10 through the hollow box 9; the ice plate 10 melts after absorbing the heat, thereby achieving heat dissipation for the charging box; finally, open the solenoid valve 4 and discharge the water source through the drain pipe 5; this step helps to remove the waste generated during the heat dissipation process and ensure the cleanliness of the inside of the charging box; in addition, this design also avoids safety hazards such as explosion of the charging box due to overheating.

[0033] Reference Figure 1 and Figure 3The harness mechanism 2 includes a fixing frame 201, which is fixedly connected to the left side of the outer wall of the box body 1, and a fixing rod 203 is fixedly connected to the inner side of the fixing frame 201. Torsion springs 202 are arranged on the front and rear ends of the outer wall of the fixing rod 203. The ends of the torsion springs 202 that are far away are respectively fixedly connected to the front and rear sides of the inner wall of the fixing frame 201. A rotating plate 204 is rotatably connected to the middle part of the front and rear sides of the rotating plate 204. The adjacent ends of the torsion springs 202 are respectively fixedly connected to the middle parts of the front and rear sides of the rotating plate 204. The left side of the rotating plate 204 and the lower and middle parts of the left side of the box body 1 are fixedly connected with an arc plate 205; a connecting cable 8 is installed at the front end of the left side of the box body 1, and the connecting cable 8 is passed through the inner side of the arc plate 205; the front and rear ends of the left side of the upper arc plate 205 are threadedly connected with bolts 18, and the two arc plates 205 are threadedly connected by the bolts 18;

[0034] Specifically, first the operator needs to flip the arc plate 205, and this action will simultaneously drive the fixed rod 203 to be subjected to force; the function of the fixed rod 203 is to transmit the force to the torsion spring 202 so that it can store energy; this process is equivalent to charging the torsion spring 202 and preparing for the next operation; next, when the torsion spring 202 has finished storing energy, the operator can drive the rotating plate 204 to flip; through this operation, the two arc plates 205 can be smoothly merged together; this step is to ensure that the connecting cable 8 is firmly fixed between the two arc plates 205 to prevent loosening; finally, the operator takes the bolt 18 and connects the two arc plates 205; in this way, the wiring process of the connecting cable 8 is completed; this operation method effectively avoids the situation where the charging is loose and the power is not supplied due to the shaking of the connecting cable 8, thereby improving the production efficiency and the service life of the equipment.

[0035] Reference Figure 2 The left and right ends of the rear side of the fixing box 17 are both threadedly connected with rivets 13, and the fixing box 17 is threadedly connected to the box body 1 through the rivets 13;

[0036] Specifically, the fixing box 17 is connected to the box body 1 through the rivets 13 .

[0037] Working principle: When the battery charging box of the plant protection drone is subjected to the heat dissipation process, the rotating plate 6 is rotated to open the hollow box 9, and the ice plate 10 is placed in the hollow box 9. The hollow box 9 is taken and the arc rod 3 is aligned with the fixed box 17. At the same time, the hollow box 9 is pressed down to make the sawtooth bar 16 mesh with the gear 11 for transmission, thereby driving the gear 11 to rotate. When the sawtooth bar 16 is pressed down to the bottom position, the limit plate 15 is flipped, and the rotating shaft 14 is rotated to insert the limit plate 15 into the slot 12, and at the same time, it is stuck in the teeth of the gear 11 to fix the position of the sawtooth bar 16, and then the hollow box 9 is installed and fixed. When the charging box is in operation, the heat is transferred to the ice plate 10 through the hollow box 9. The ice plate 10 is melted and the charging box is cooled. The solenoid valve 4 is opened to discharge the water through the drain pipe 5, thereby avoiding safety hazards such as explosion of the charging box due to overheating, and meeting the needs of use. The flipping of the arc plate 205 simultaneously drives the fixing rod 203 to be subjected to force. The force of the fixing rod 203 is transmitted to the torsion spring 202, so that the torsion spring 202 stores energy and drives the rotating plate 204 to flip, thereby merging the two arc plates 205. The bolts 18 are taken to connect the two arc plates 205, completing the wiring process of the connecting cable 8, avoiding the situation where the charging is loose and power is not supplied due to the shaking of the connecting cable 8, and bringing convenience to use.
