[0032] Specifically, the angle adjustment assembly 25 includes a second motor 251 fixedly connected to the bottom of the U-shaped frame 23 , and a driving gear 252 is fixedly connected to the output end of the second motor 251 .

[0033] Specifically, the fog cannon assembly 3 includes a fog cannon bracket 31, the bottom of which is fixedly connected to one end of a rotating shaft 32, the other end of the rotating shaft 32 passes through the U-shaped frame 23 and is fixedly connected to a driven gear 33, the driven gear 33 is meshed with the driving gear 252, and a fog cannon body 34 is rotatably connected to the fog cannon bracket 31.

[0034] As can be seen from the above, the device can be moved to a designated position for use by driving the vehicle 11, and the motor 241 is controlled. The output end of the motor 241 drives the worm 242 to rotate, and the worm 242 drives the worm wheel 222 to rotate, and the worm wheel 222 drives the ball screw body 221 to rotate. The rotation of the ball screw body 221 can make the U-shaped frame 23 smoothly rise and fall in the vertical direction to the required designated height.
