[0022] The all-terrain AGV vehicle 1 is purchased from outside using existing technology.

[0023] The cover 2-2 is made of transparent acrylic.

[0024] The working principle of this utility model is:

[0025] The all-terrain AGV vehicle 1 can move by itself by setting a route. The coordinates of the antenna to be installed are input on the all-terrain AGV vehicle 1, and then the all-terrain AGV vehicle 1 automatically moves to the coordinates where the antenna to be installed is required. This can reduce the need for manual labor to carry a large amount of equipment, and can be used for climbing in the mountains or crossing in the wild, shortening the antenna installation time and ensuring the safety of personnel. After arriving at the designated installation location, the photovoltaic panel 1-1 is exposed to sunlight to generate electricity and transmits it to the battery 2-3 for storage. During the day, the photosensitive sensor 3-10 senses the change in light and controls the power controller 3-9 to turn on. The power controller 3-9 turns on to extend the electric telescopic rod 3-8, driving the control box 3-6 and the antenna main board 3-1 and the antenna sub-board 3-2 to move upward, and the two cover plates 2-2 are opened until the antenna main board 3-1 and the antenna sub-board 3-2 move to the outside of the box body 2-1. The electric telescopic rod 3-8 stops working, and the power controller 3-9 turns on to generate heat on the heating rod. As the heat gradually increases, the two ends of the curling plate 3-7 begin to curl. The antenna sub-plate 3-2 is bent and the steel cable 3-5 is pulled to unfold to both sides with the antenna main plate 3-1 as the center, and the spring 3-3 is stretched at the same time. The spring 3-3 resets the antenna sub-plate 3-2, and the pulley 3-4 reduces the friction of the steel cable 3-5. After the antenna sub-plate 3-2 is unfolded, the heating rod stops heating, and then the signal can be received or transmitted. The received signal or the transmitted signal is received or transmitted by the signal transmitter 2-4. At night, the light sensor 3-10 senses that the light is dim, controls the power controller 3-9 to turn on, energizes the heating rod, resets the curling plate 3-7, and releases the steel cable 3-5. Then, the spring 3-3 drives the antenna sub-plate 3-2 to fold and reset. Then the power controller 3-9 controls the electric telescopic rod 3-8 to retract, driving the antenna main plate 3-1 to retract into the box body 2-1. At the same time, the coil spring drives the cover plate 2-2 to reset, which can avoid the problem that the antenna cannot be retracted when there is no need to receive or transmit signals at night, and then the antenna will be eroded by wind and cause interference.

[0026] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
