Through the setting of the shielding adjustment mechanism 9, the shielding adjustment mechanism 9 adjusts the magnetic field shielding ability of the shielding shell 4 to the electronic device 7, thereby ensuring that the electronic device 7 can operate safely in the strong magnetic field area of ​​the power transmission line; specifically, when the shielding adjustment mechanism 9 is not started, the telescopic rod 92 controls the mesh frame 93 to drive the support rod 94 to move, so that the filter Block 96 is located at the heat dissipation hole 41. At this time, the gas in the upper chamber 42 and the lower chamber 43 can penetrate back and forth through the filter block 96. Through the action of the heat dissipation mechanism 5, the heat in the upper chamber 42 and the lower chamber 43 is dissipated. When the shielding adjustment mechanism 9 is started, the telescopic rod 92 controls the mesh frame 93 to drive the support rod 94 to move, so that the metal block 95 is located at the heat dissipation hole 41. At this time, the metal block 95 fills the heat dissipation hole 41 opened on the shielding shell 4, so that the shielding shell 4 is in a closed structure, thereby enhancing the shielding effect of the shielding shell 4 against the external magnetic field.

[0027] In this embodiment, the metal block 95 is made of the same metal material as the shielding shell 4 , so as to enhance the shielding effect of the shielding shell 4 .

[0029] In this embodiment, the height of the filter block 96 is greater than the hole height of the heat dissipation hole 41, so that the gas in the shielding shell 4 can be exchanged with the gas outside the shielding shell 4, thereby ensuring the purity of the gas inside the shielding shell 4, further making the environment of the electronic device 7 cleaner, and ensuring the safe operation of the electronic device 7.

[0030] In this embodiment, a magnetic field sensor 8 for monitoring the magnetic field strength of the power transmission line is also installed on the body 1; specifically, a warning value for the safe operation of the electronic device 7 is set for the magnetic field sensor 8, and when the monitoring value of the magnetic field sensor 8 reaches the warning value, the shielding adjustment mechanism 9 is started.

The gas located in the heat dissipation hole 41 area passes through the air permeability and filtering effect of the filter block 96, so that the heat in the upper chamber 42 and the lower chamber 43 can also be dissipated, thereby having a heat dissipation effect on the inside of the shielding shell 4, so that the shielding shell 4 has a higher shielding protection effect. At the same time, the heat inside the shielding shell 4 is effectively dissipated, and when the shielding adjustment mechanism 9 is started, at this time, the upper and lower end faces of the shielding shell 4 are in a sealed structure, and the motor 57 drives the fan 58, and the external gas will impact the side and upper and lower end faces of the shielding shell 4, thereby having a heat dissipation effect on the side and upper and lower end faces of the shielding shell 4, thereby continuously ensuring the heat dissipation and cooling treatment of the shielding shell 4, and ensuring the safe operating environment of the electronic device 7.

[0032] In this embodiment, the filter frame 55 includes a strip plate 551 installed on the lifting frame 54, and a filter strip 552 is installed on the side panel surface of the strip plate 551 close to the shielding shell 4, and the filter strip 552 is in contact with the side panel surface of the shielding shell 4.

When the drone is started to inspect the transmission line, the transmission line is inspected by the photographic mechanism 6, and the size of the external magnetic field during the inspection is monitored by the magnetic field sensor 8. When the magnetic field sensor 8 reaches the warning value, the shielding adjustment mechanism 9 is started until the monitoring value of the magnetic field sensor 8 is lower than the set warning value, and then the shielding adjustment mechanism 9 is closed again. The heat dissipation mechanism 5 is used to dissipate heat and clean the shielding shell 4, thereby ensuring that the electronic device 7 can be efficiently dissipated under the condition of safe operation, thereby ensuring the safe operation of the electronic device 7.
