The present invention can complete the positioning and installation processing of the present structure through the design of an engineering plastic mounting seat, and at the same time, through the design of elastic parts and rubber sleeves, the conductive ring seat as a whole can be elastically connected to the mounting surface, and at the same time, through the design of a vibration motor, the conductive ring seat as a whole can be driven to vibrate significantly, and the force generated by the vibration causes the ice layer attached to the outer surface of the lightning rod body to fall off, thereby avoiding the problem that the ice layer will affect the lightning protection effect of the lightning rod body, and improving the reliability of the present structure.

The fixed base 216 is respectively provided with an inner ring 214 and an outer ring 215. The outer ring 215 is arranged on the outer side of the inner ring 214. The bottom of the inner protective shell 212 is connected between the inner ring 214 and the outer ring 215. The inner protective shell 212 cooperates with the connection of the fixed base 216 to facilitate the covering of the device box 102 on the inner side. At the same time, the bottom of the inner protective shell 212 provides further sealing on the inner side through the inner ring 214 and the outer ring 215, which is beneficial to further reduce the entry of dust and impurities into the interior, effectively avoid the damage of the device box 102 caused by the entry of external impurities, and is beneficial to extend the service life of the lightning protection device.

[0024] like Figure 2 As shown, a plurality of second sealing rubber rings 213 are distributed on the top of the inner protective shell 212, and a first sealing rubber ring 202 is arranged on the top of the insulating protective box 201. The second sealing rubber ring 213 is arranged on the inner protective shell 212 to facilitate further sealing of the fixed column 204 penetrating therethrough at the connection joint.

After the connection is completed, the insulating protection box 201 is opened by rotating the base, the power is started, and the base is rotated and installed. Then, the fixed base 216 is installed on the equipment by bolts. When foreign debris falls on the lightning rod 101, or ice forms on the lightning rod 101, the weight of the lightning rod 101 increases, causing the lightning rod 101 to move downward, driving the lower air buffer bag downward, and when the lower air buffer bag contacts the gravity sensor, the gravity sensor transmits gravity to the information transmission device on the circuit board, and then The information transmission device will transmit the gravity information to the mobile terminal, which is convenient for the user to monitor the gravity. The air pump 310 adds gas to the interior of the air pressure tank 309 and stores it through the air pressure tank 309. The air pressure tank 309 is provided with a valve body 308 and connected to the jet ring 301 through a telescopic hose 307.
