The baffle completely blocks the heat dissipation port of the chassis, so that the baffle can automatically block the heat dissipation port of the chassis on rainy days, allowing the baffle to block raindrops from splashing into the chassis, thereby preventing raindrops from splashing into the equipment when the multifunctional protection device is used on rainy days, causing a short circuit and damage to the roadside load switch. In addition, the L-shaped short plate abuts against the front of the box door during the upward movement, so that the box door is restricted by the L-shaped short plate, so that the box door on the chassis will not be accidentally opened on rainy days, thereby preventing the multifunctional protection device from accidentally opening the box door on rainy days, causing the roadside load switch to be eroded and damaged by rainwater.

[0018] (2) The present invention arranges the maintenance device so that the support rod, the circular shell, the arc spring sheet, the arc plate, the sponge block, the ring plate, the concave circular shell and the arc block cooperate with the chamfer plate. Under the elastic force of the arc spring sheet, the sponge block will be tightly pressed against the screw rod, and the sponge block will wipe the screw rod, so that the sponge block will evenly apply the lubricating oil on the screw rod, thereby preventing the screw rod in the multifunctional protection device from rusting and aging, which will cause poor operation of the equipment. In addition, the spiral groove of the screw rod rotates forward on the chamfer plate, and the chamfer plate will scrape off foreign matter in the screw rod during the upward movement, thereby preventing foreign matter from being stuck in the multifunctional protection device and causing the equipment to jam.

[0019] (3) The present invention arranges a drying device so that the F-shaped rod, the circular frame, the dehumidification module, the liquid guide tube, the E-shaped slide plate, the heat conduction plate and the back plate cooperate with the L-shaped block. The dehumidification module moves to the front of the switch body, and the dehumidification agent in the dehumidification module absorbs the moisture in the chassis. The moisture absorbed by the dehumidification module forms water droplets and is discharged from the liquid guide tube, thereby reducing the moisture in the chassis from accumulating next to the switch body, and preventing the multifunctional protection device from being used on rainy days. Moisture accumulates under the chassis and causes the roadside load switch to be damaged by moisture. When the weather clears up, the dehumidification module moves to the back of the heat conduction plate, and the heat conduction plate generates heat when exposed to light. The heat conduction plate transfers the heat to the dehumidification module, and the dehumidification agent in the dehumidification module begins to dehydrate, so that the dehumidification agent in the equipment can be recycled, and the frequent replacement of the dehumidification agent in the multifunctional protection device causes an increase in the workload of the staff.
