The support mechanism 18 includes an extension plate 5 and a support seat 6, and the side of the extension plate 5 close to the support base 1 penetrates into the inner cavity of the support base 1.

[0021] See also Figure 2 Both sides of the top of the connection shell 9 are plugged with connection cables, and the front side of the bottom of the sliding protective cover 13 is hot-melt connected with a dust-proof wool belt 11 used in conjunction with the connection cable.

[0022] See also Figure 3 A holding plate 12 is welded to the rear side of the sliding protective cover 13, a plug-in slot 10 for use with the sliding protective cover 13 is provided on the top of the rear side of the cable protection mechanism 4, and an observation mirror 2 is installed through the top of the sliding protective cover 13.

[0023] See also Figure 2 Support rods 16 are welded on both sides of the front side of the support frame 19. By setting the support rods 16, the photovoltaic inverter integrated board 3 can be balanced and supported, thereby improving the support stability of its main body. The photovoltaic inverter integrated board 3 is welded on the side of the support rod 16 away from the support frame 19. By setting the photovoltaic inverter integrated board 3, solar energy can be converted into electrical energy to power the axial flow fan 17. The axial flow fan 17 is embedded and installed on the front side of the support frame 19.

[0024] See also Figure 2 Both sides of the connecting shell 9 are connected to the connecting shell 7, and a dust filter 8 is embedded and installed on the top of the connecting shell 7.

[0025] See also Figure 4A limiting plate 15 is welded on the opposite side of the two extension plates 5. By setting the limiting plate 15, the extension plate 5 can be limited to prevent it from falling off from the inner cavity of the support base 1. The limiting plate 15 is slidably connected to the connection between the inner wall of the support base 1, and the bottom of the support base 6 is hot-melt connected with a metal contact pad 14. By setting the metal contact pad 14, the contact area between the support base 6 and the ground can be increased without affecting the lightning protection function.

[0026] During use, when it is necessary to dissipate heat at its internal connections, the photovoltaic inverter integrated panel 3 converts solar energy into electrical energy, which is then transmitted to the axial flow fan 17. The axial flow fan 17 then blows air to accelerate the air flow in the inner cavity of the connecting shell 9, thereby accelerating the discharge of heat through the connecting shell 7 and the dust filter 8, and filtering dust and impurities at the same time. When it is necessary to improve the support stability of the main body of the device, the user can manually pull the support seat 6 to drive it to move, so that it drives the extension plate 5 to extend, thereby increasing the support area to improve the support stability of the main body.

[0027] In summary: the current transmitter with lightning protection solves the problem that the service life is affected by self-heating and the main body support stability is generally poor by setting the connecting shell 7, the dust filter 8, the connecting shell 9, the plug-in slot 10, the dust-proof hair belt 11, the holding plate 12 and the sliding protective cover 13.
