[0023] Specifically, the laser pumping body 2 includes a laser pumping module 21, an outer housing 22, an end plate 24 and a mounting plate 25. One end of the outer housing 22 is open. Inside the outer housing 22, there are a laser pumping module 21 and a heat dissipation mechanism. Inside the open end of the outer housing 22, there are several mounting plates 25. At the open end of the outer housing 22, there is an end plate 24. The end plate 24 is fixed to the mounting plate 25 by bolts. A wire port is provided on the end plate 24. The optical fiber of the laser pumping module 21 is led out of the end plate 24 through the wire port and connected to the pan-tilt lens 1. The laser pumping module 21 is clamped between the heat dissipation mechanism and the end plate 24. The laser pumping module 21 is installed for heat dissipation, and the laser pumping module 21 is convenient to disassemble and assemble inside the outer housing 22.

[0024] Furthermore, the heat dissipation mechanism includes a radiator 23 and a cooling fan 26. A number of evenly distributed heat dissipation openings are provided on one side of the outer housing 22 away from the end plate 24 and on the end plate 24. Inside the outer housing 22 at the end away from the end plate 24, there is a cooling fan 26. Inside the outer housing 22 on the side of the cooling fan 26 close to the end plate 24, there is a radiator 23. The laser pumping module 21 is clamped between the radiator 23 and the end plate 24. Under the action of the cooling fan 26, the external low-temperature air enters the inside of the laser pumping body 2 through the heat dissipation openings on the end plate 24. The radiator 23 conducts heat from the laser pumping module 21 to the surrounding air. The circulation of the air inside the outer housing 22 discharges the high-temperature air inside the laser pumping body 2, realizing the heat conduction and circulation heat dissipation installation of the laser pump.

[0025] Furthermore, the radiator 23 includes a first heat sink 231 and a second heat sink 232. Inside the outer housing 22 on the side of the cooling fan 26 close to the end plate 24, there is a first heat sink 231. On the side of the first heat sink 231 away from the cooling fan 26, there is a second heat sink 232. The second heat sink 232 is arranged between the laser pumping module 21 and the outer housing 22. The side of the second heat sink 232 away from the laser pumping module 21 is fixed to the inner wall of the outer housing 22. The first heat sink 231 and the second heat sink 232 conduct heat from the laser pumping module 21 to the surrounding air, that is, the laser pumping module 21 is installed for heat conduction and heat dissipation inside the outer housing 22.

[0026] Furthermore, the first heat sink 231 is arranged in a disc-shaped structure. There are several second heat sinks 232. The side of the first heat sink 231 away from the cooling fan 26 and the side of the second heat sink 232 away from the outer housing 22 are both in contact with the outer surface of the laser pumping module 21. The heat dissipation contact area is large. A dust-proof net is provided inside the heat dissipation opening to prevent dust.

[0028] Furthermore, the heights of the bottom of the pan-tilt lens 1 and the laser pumping body 2 are set higher than the support height of the bottom of the support frame 8 to prevent the pan-tilt lens 1 and the laser pumping body 2 from contacting the ground and colliding when the UAV lands.

[0029] The usage method of this embodiment is as follows: The laser pumping module 21 is installed inside the radiator 23 through the opening of the outer housing 22. The internal size of the radiator 23 is the same as that of the laser pumping module 21. The end plate 24 and the mounting plate 25 are fixedly installed by bolts.

That is, one side of the first heat sink 231 away from the cooling fan 26 and one side of the second heat sink 232 away from the outer housing 22 are both in contact with the outer surface of the laser pumping module 21. The optical fiber on the laser pumping module 21 is led out from the wire port of the end plate 24 and connected to the pan-tilt lens 1. The laser pumping body 2 with a heat dissipation mechanism is installed. The installation block 42 at the top of the installation frame 41 is inserted into the installation seat 43 and fixed by bolts. The laser pumping body 2 is installed on the UAV body 5 on one side of the pan-tilt lens 1 through the installation mechanism 4. The pan-tilt lens 1 and the laser pumping body 2 on the UAV body 5 are used for the UAV to carry out laser foreign object removal work. Under the action of the cooling fan 26, the external low-temperature air enters the inside of the laser pumping body 2 through the dust-proof net through the heat dissipation port on the end plate 24. The first heat sink 231 and the second heat sink 232 conduct heat of the laser pumping module 21 to the surrounding air. The circulation of the air inside the outer housing 22 discharges the high-temperature air inside the laser pumping body 2, realizing the heat conduction and circulation heat dissipation installation of the laser pump. The heat dissipation surface is large and the heat dissipation performance is high. The laser pumping module 21 is clamped between the radiator 23 and the end plate 24. The installation of the laser pumping module 21 has good heat conduction and heat dissipation performance and is convenient for disassembly and assembly. Moreover, the laser pumping body 2 is convenient to disassemble and install on the UAV and is firmly installed.
