A rain cover 5 is fixedly installed on the top of the connecting column 12. Through the operation of one of the gears 17, the transmission ring 18 and the tooth group 19 are driven to operate, and then the remaining gears 17 can be driven to operate, so that multiple gears 17 can operate synchronously while driving the connecting rod 1 20 and the connecting rod 2 21 to operate synchronously, so that the height of the connecting column 12 and the rain cover 5 can be adjusted. In rainy weather, the cabinet 2 can be shielded by moving the rain cover 5 downward to prevent rain from interfering with the outer wall of the cabinet 2, thereby keeping the internal environment of the cabinet 2 dry and having good moisture-proof performance.

[0023] An exhaust fan 22 is fixedly installed inside the cabinet 2 and at the bottom of the installation cabinet 9. A ventilation slot is opened at one end of the cabinet 2, and a filter plate 3 matching it is arranged inside the ventilation slot. The exhaust fan 22 cooperates with the ventilation slot. By cooperating with the ventilation slot, the air circulation speed inside the cabinet 2 can be accelerated, thereby dissipating the heat of the electronic components and stabilizing their working efficiency. A mounting plate 13 is fixedly installed around one end of the filter plate 3. The internal thread of the mounting plate 13 is connected with a bolt 14. The bolt 14 is threadedly connected to the cabinet 2. The filter plate 3 can be stably installed through the set bolt 14, and it is convenient to replace and clean.

The motor 15 is provided to drive one of the gears 17 to operate, and the operation of one of the gears 17 drives the transmission ring 18 and the tooth group 19 to operate, and then the remaining gears 17 can be driven to operate, so that multiple gears 17 can operate synchronously while driving the connecting rod 1 20 and the connecting rod 2 21 to operate synchronously, so that the height of the connecting column 12 and the rain cover 5 can be adjusted, and the groove provided at the bottom of the rain cover 5 cooperates with the installation cabinet 9, so that the bottom of the rain cover 5 is relative to the cabinet body. The top of the cabinet 2 is relatively low, so the rain can be shielded by the rain cover 5, and because the rain cover 5 is arranged in the shape of an eave, it has good drainage for rain. Rainwater falls on the rain cover 5 and falls on the ground along its inclination angle, thereby preventing the rain from interfering with the outer wall of the cabinet 2. On sunny days, it can be raised to increase its light receiving area and speed up the drying speed of the surrounding ground, thereby having a good moisture-proof effect. The air circulation speed inside the cabinet 2 can be accelerated by the exhaust fan 22 and the ventilation slot, so that it has a good heat dissipation effect. The dust in the air can be filtered by the filter plate 3, thereby preventing the dust from affecting the normal operation of the electronic components.
