[0021] Example 1, please refer to Figure 1-Figure 5 As shown, this embodiment is an intelligent outdoor switchgear, comprising a switchgear box 100 with an opening on the front; The protective structure 200 includes an inner shell 202, a shielding plate 215 between the inner shell 202 and the switch box 100, a nut 206 at one end of the shielding plate 215, a motor 204 located inside the lower end of the switch box 100, a screw 205 located at the output end of the motor 204 and rotatably plugged into the nut 206, an arched frame 212 located inside the storage groove 209 and outside the shielding plate 215, and a hot air blower 201 located at the upper end of the switch box 100 and with the output end passing through the arched frame 212; A split closing door 101 is rotatably installed at the opening of the switchgear box body 100. Baffles 203 are sleeved outside both the motor 204 and the screw rod 205, and the lower ends of the baffles are connected to the bottom frame 301. A bearing bracket 207 is arranged at the upper end of the bottom frame 301, and one end of the screw rod 205 is rotatably inserted into the interior of the bearing bracket 207. A travel groove 208 is formed inside the inner shell 202, and the nut 206 is slidably installed inside the travel groove 208. Support seats 211 are arranged on both sides at the lower end of the shielding plate 215. Equally spaced balls 214 are rotatably installed inside the lower ends of the support seats 211. Slide seats 210 are arranged at the upper end of the bottom frame 301 and are symmetrically distributed inside the storage groove 209, and the balls 214 are rotatably installed inside the slide seats 210. Air openings 213 are formed on the inner wall of the arched frame 212. The arched frame 212 has a "C" - shaped structure, and the air openings 213 also have a "C" - shaped structure. Moreover, the air openings 213 are provided with inclined surfaces, and the inclined surfaces face the opening of the switchgear box body 100. The switchgear box body 100 is welded to the bottom frame 301. The hot air blower 201 is fixedly installed on the switchgear box body 100 through the mounting bracket. When the inner shell 202 is installed, it is slidably inserted into the interior of the switchgear box body 100, and is in contact with the rear inner wall of the switchgear box body 100. The lower end is in contact with the bottom frame 301, and the space reserved between it and the switchgear box body 100 forms the storage groove 209. Subsequently, the contact ends of the inner shell 202 with the switchgear box body 100 and the bottom frame 301 are welded. It should be noted that because the "C" - shaped shielding plates 215 are installed at both ends and above the switchgear box body 100, both the arched frame 212 and the shielding plates 215 are composed of two side plates and one top plate connected in sequence on the left and right sides, forming a "C" - shaped structure. The heat dissipation window and the wiring reserved interface of the switchgear box body 100 are located inside the rear end of the switchgear box body 100. The closing door 101 adopts the traditional switchgear closing door 101 and can be locked after closing. When the switchgear box body 100 is maintained and in high - temperature, rainy or snowy weather, the opening of the closing door 101 of the switchgear box body 100 is opened. The motor 204 operates to drive the screw rod 205 to rotate, push the nut 206, and drive the shielding plate 215 to move outward. The bottom of the shielding plate 215 is slidably supported by the balls 214. The extended shielding plate 215 shields the sunlight, preventing maintenance personnel from being exposed to the sun. At the same time, it intercepts rain and snow, preventing the staff from being wet by rain and snow. The comfort during the maintenance of the switchgear box body 100 is improved, and rain and snow are prevented from entering the interior of the switchgear box body 100, resulting in secondary damage to electrical components during the maintenance process. The equipment inside the switchgear box body 100 realizes intelligent regulation during maintenance in bad weather, and the switchgear box body 100 is effectively protected by the extended shielding plate 215. When the shielding plate 215 is stored after use, the hot air blower 201 operates to transport the hot air flow into the arch frame 212, and the air outlet 213 inside the arch frame 212 outputs the hot air flow to blow the rain and snow on the outer wall of the shielding plate 215 to the outside, preventing rain and snow from being brought into the opening and closing box 100, and the disadvantages of the shielding plate 215 after use are effectively avoided.

[0022] Example 2, please refer to Figure 1-Figure 5 As shown, this embodiment is based on the embodiment 1 and also includes: as well as; The lifting structure 300 includes a bottom frame 301, an outer cylinder 302 located at the four corners of the lower end of the bottom frame 301, an inner cylinder 303 located inside the outer cylinder 302, a liquid level sensor 308 located inside the inner cylinder 303, a travel port 307 opened inside the side of the outer cylinder 302, an air pump 310 located at the lower end of the bottom frame 301 and with the output end passing through and installed inside the bottom frame 301, and air holes 309 located at the four corners of the bottom frame 301 and communicating with the outer cylinder 302.

[0023] The inner wall of the outer cylinder 302 is provided with a sliding sleeve 304, and the inner cylinder 303 is slidably inserted into the sliding sleeve 304; An annular support ring 305 is provided on the outer wall of the lower end of the inner cylinder 303. The support ring 305 is located below the outer cylinder 302. A mounting ring 306 is provided at the lower end of the inner cylinder 303. The mounting ring 306 is provided with mounting holes distributed in an annular array. The mounting ring 306 is butted against the poured pile foundation through the mounting hole, and the outer cylinder 302 is welded to the bottom frame 301 and is located at the four corners of the lower end of the bottom frame 301, providing multi-point support for the lower end of the bottom frame 301. The opening and closing box 100 is fixed on the pile foundation. After the accumulated water on the ground rises, the accumulated water enters the inner cylinder 303 through the stroke port 307. When the liquid level sensor 308 detects that the accumulated water reaches the warning height, it transmits a signal to the terminal. The terminal controls the operation of the air pump 310 to transport the pressure medium into the inner cylinder 303. The pressure acts on the internal space of the inner cylinder 303 and the outer cylinder 302 through the air hole 309. It is worth mentioning that the upper end of the liquid level sensor 308 divides the inner cylinder 303 into two spaces through the closing plate. The pressure medium is located in the space inside the upper end, pushing the outer cylinder 302 to achieve the sliding of the outer cylinder 302 on the outer wall of the inner cylinder 303. The outer cylinder 302 is lifted, and then the switch box 100 is lifted, which plays a role in isolating the accumulated water and reducing the risk of the inside of the switch box 100 being soaked by accumulated water. The intelligence of the switch box 100 is improved. It is worth mentioning that the external cable of the switch box 100 needs to be set with redundant length to ensure the stable use of the switch box 100 during the lifting process.
