[0044] A vertical shaft 218 is rotatably connected to the top of the protective box 103 and near the rotating shaft 1 202. A square plate 219 is fixedly connected to the top of the protective box 103 and near the vertical shaft 218, and the square plate 219 and the vertical shaft 218 are at the same level.

[0048] Working principle: When the present invention is used, firstly, the mounting frame 1 is fixedly installed at the required position outdoors through the side plate 101, and then the gateway device body 105 is arranged inside the protective box 103, and then the wiring harness to be connected is inserted into the protective box 103 through the wiring harness hole 302, and then the upper bottom plate 306 is pressed downward so that its two sets of limiting plates 304 can complete the limiting clamping work of the wiring harness, thereby preventing rats and insects from flying into the protective box 103 through the wiring harness hole 302, and when the screw rod 312 is level with one of the limiting holes 311, the screw rod 312 can be rotated, so that one end of the screw rod 312 can be inserted into the limiting hole 311, and the limiting work of the plug shaft 305 and the upper bottom plate 306 is realized, thereby solving the problem that rats and insects can easily enter the protective shell from the wiring port of the protective shell to damage the gateway device, thereby reducing the stability and reliability of the gateway device;

[0049] By running two cooling fans 106 and cooperating with two groups of cooling holes 213, the effect of cooling the inside of the protective box 103 can be achieved. When dust appears above the cooling holes 213, the motor 1 201 can be operated to rotate the fixedly connected second gear 215, and then the rotating shaft 1 202 is rotated and drives the turntable 203 to rotate under the action of the meshing first gear 214. Subsequently, under the cooperation of the three protrusions 204, the moving wheel 210 and the spring 1 207, the two slide cylinders 208 are intermittently inserted into the side ends of the sleeve 206, so that the vertical plate 1 209 drives the push frame 211 and the scraper plate 212 to move back and forth horizontally, thereby achieving the work of clearing the dust above the cooling holes 213, which is convenient for the cooling fan 106 to clean the inside of the protective box 103. To dissipate heat, at the same time, the rotation of shaft 1 202 can drive bevel gear 1 216 to rotate, and then under the action of shaft 220 and two bevel gears 221, the meshing bevel gear 3 222 drives the vertical shaft 218 to rotate. At this time, the disk 223 fixedly connected thereto will drive the short shaft 226 to rotate, and then, under the cooperation of connecting rod 227 and short shaft 1 225, the sliding rod 224 can drive the defog brush 228 to move back and forth on the surface of the observation window 217, completing the defog operation of the observation window 217, preventing the protective box 103 from being filled with thick fog and making it impossible to view the inside through the observation window 217, thereby solving the problem that outdoor dust will gradually adhere to the heat dissipation port, causing the heat dissipation port to be blocked and affecting the heat dissipation.
