[0023] like Figure 3 As shown, a solar panel 41 is fixedly installed on one side of the top surface of the protection box 4, and the output end of the solar panel 41 is electrically connected to a photovoltaic inverter 42, and the output end of the photovoltaic inverter 42 is electrically connected to a battery 43. The solar panel 41 converts solar energy in the external environment into electrical energy, which is processed by the photovoltaic inverter 42 and stored in the battery 43. The stored electrical energy can be used by the shielding device body 1 and other electrical equipment, thereby reducing the electrical energy consumed by the shielding device of the signal interference.

[0024] like Figure 2 As shown, a heat dissipation port 44 is provided on one side of the protection box 4, and a plurality of heat dissipation fans 45 are provided on one side of the heat dissipation port 44. The heat dissipation fans 45 are fixedly installed on the top surface of the mounting base plate 3.
