[0021] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0022] 1. A moisture-proof protection mechanism is provided, and the air entering the substation box and the gas inside the box are dried and dehumidified by using the storage box and block silica gel desiccant, so that the air inside the substation box remains dry, and the humid gas is prevented from being retained inside the substation box for a long time, causing the electrical components to rust and affect their normal operation. At the same time, the protective frame and the rainproof inclined plate cover and protect the storage box, so that the storage box remains close to the surface wall of the substation box, and the storage box is prevented from tilting and shaking or the rain from the outside causing moisture inside;

[0023] At the same time, weighing sensors and extruded long plates are used to monitor the weight of the block silica gel desiccant inside the storage box. As the block silica gel desiccant continues to absorb moisture, its own weight will increase. Its weight is monitored in time for subsequent processing. The interception strips and vents increase the contact area between the block silica gel desiccant and the air. The interception strips block the block silica gel desiccant, allowing it to fully absorb moisture inside the substation box without falling off.

[0024] 2. The electric telescopic rod is used to drive the lifting rack and the connecting frame to rise and fall, and the driving rack is meshed with the reversing gear, so that the reversing gear and the driving gear are meshed and rotated with each other, and then the driving gear and the driving extension rod are rotated, corresponding to the driving convex rod, the driving convex rod and the rotating disc are pushed to rotate, and the rotating seat and the protective frame position are rotated and adjusted. The protective frame and the rainproof inclined plate are removed in advance before the storage box rotates, and the lifting rack is meshed with the rotating gear, so that the storage box and the rotating block rotate, so that the storage box is horizontal, and then the intercepting bar is facing upwards, exposing the block silica gel desiccant, and using sunlight to dry and dehumidify it, so that the block silica gel desiccant can be used repeatedly for a long time, and the control method is simple.

[0025] 3. Use locking strips and positioning grooves to lock and adjust the position of moisture-proof boards and protective covers. When moving the substation box, the moving wheels provide certain conveniences, without the need for high-intensity lifting. At the same time, after installation, the protective cover is used to cover the bottom and the moving wheels. The moisture-proof boards and protective covers at the bottom of the substation box play a role in moisture-proofing. After the protective cover is embedded in the ground, the soil is isolated from the electrical components inside the substation box, reducing moisture from entering the substation box.

[0026] 4. A temperature control mechanism is provided. The light-transmitting glass can be used to allow sunlight to penetrate into the substation box in cold weather and sunshine, and the temperature inside the substation box can be increased by sunlight, so as to prevent the electrical components from not being able to operate normally due to the low temperature inside the substation box. At the same time, the light-transmitting glass can be covered with a spliced ​​sunshade in hot weather to prevent direct sunlight in hot weather;

[0027] The position of the spliced ​​shading plates can be adjusted by using a driving motor and a rotating gear, which drives the spliced ​​shading plates and a rotating column to rotate, so that the spliced ​​shading plates are dispersed and spread outward or spliced ​​and merged inward.

[0028] 5. The focusing convex lens moves with the protective frame. When the storage box rotates and unfolds, the focusing convex lens is pulled and moved above the storage box. The focusing convex lens is used to refract sunlight so that the light is concentrated and irradiated on the surface of the storage box to dry the block silica gel desiccant. The focusing convex lens increases the drying rate, and the cleaning pad cleans the focusing convex lens when it returns to its original position, keeping its surface clean.

[0029] 6. Use a condenser to gather sunlight and monitor the sunlight and temperature outside. The sunlight shines on the heat transfer plate through the condenser to increase its temperature. The temperature is used to adjust the volume of the heat expansion pad to press down the extrusion block and the pressure sensor. When the sunlight temperature reaches a certain level, the storage box is rotated and the position of the spliced ​​sunshade is adjusted, so that it can be remotely controlled to prevent the sun exposure process from being unsmooth due to rainy weather adjustments.

[0030] In summary, by combining the moisture-proof protection mechanism and the temperature control adjustment mechanism, a focusing convex lens is used to increase the drying and dehumidification rate of the block silica gel desiccant, and the drying process is controlled by temperature and sunlight. The sunlight is captured by a concentrator, and the pressure sensor will transmit the signal to the outside in time, which is convenient for remote direct control and the operation method is very simple.

The focusing convex lens 409 refracts the sunlight, so that the light is concentrated and irradiated on the surface of the storage box 305 to dry the block silica gel desiccant 306. The focusing convex lens 409 improves the drying rate, and the cleaning pad 411 cleans the focusing convex lens 409 when it returns to its original position, so that its surface is kept clean.

[0058] A fixed cylinder 412 is fixedly installed in the middle of the top of the installation frame 402, a pressure sensor 413 is fixedly installed at the bottom end of the fixed cylinder 412, a guide strip 414 is symmetrically fixedly installed on the inner wall of the fixed cylinder 412, a condenser 415 is fixedly installed on the top of the fixed cylinder 412, a heat conducting plate 416 is movably installed inside the fixed cylinder 412, a heat expansion pad 417 is fixedly connected to the bottom end of the heat conducting plate 416, an extrusion block 418 is fixedly connected to the bottom end of the heat expansion pad 417, and a slide groove is provided at both ends of the heat conducting plate 416, the heat expansion pad 417 and the extrusion block 418, and the guide strip 414 is movably connected to the guide strip 414. Inside the slide, the bottom end of the extrusion block 418 is tightly attached to the top end of the pressure sensor 413, and the condenser 415 is used to gather sunlight to monitor the sunlight and temperature outside. The sunlight is irradiated to the heat conduction plate 416 through the condenser 415 to increase its temperature, and the volume of the thermal expansion pad 417 is adjusted by the temperature to press the extrusion block 418 and the pressure sensor 413 downward. When the sunlight temperature reaches a certain level, the storage box 305 is rotated and the position of the spliced ​​sunshade 404 is adjusted, so that it can be remotely controlled to prevent the adjustment of rainy weather from causing the sun exposure process to be unsmooth.

[0059] The working principle and use process of the present invention are as follows: first, the substation box 1 is moved by the moving wheel 331 and pushed to the predetermined installation position. Then, the substation box 1 is lifted up, the locking bolt 334 is screwed, the fixing of the locking strip 333 is loosened, the positioning long plate 335 and the locking strip 333 are removed, and the protective cover 332 is pulled downward so that the positioning long plate 335 corresponds to the positioning transverse groove 330 located below, and the positioning long plate 335 is inserted into the positioning transverse groove 330. Then, the locking bolt 334 is tightened so that the protective cover 332 and the moisture barrier 329 are fixed to each other, and the moving wheel 331 is moved from the through groove 336 to the inside of the protective cover 332, the moving wheel 331 is covered and hidden, and the protective cover 332 is placed at the installation position, and then the moisture barrier 329 and the protective cover 332 are isolated at the bottom of the substation box 1, so that the electrical components inside the substation box 1 are away from the soil, and moisture in the soil is prevented from penetrating into the inside of the substation box 1;

[0060] During the operation of the substation, the block silica gel desiccant 306 inside the storage box 305 absorbs moisture in the air inside the substation box 1. At the same time, the outside air enters the substation box 1 through the vent 308, the storage box 305, the dust filter plate 302 and the ventilation hole 301. When passing through the storage box 305, the block silica gel desiccant 306 absorbs moisture in the flowing air to prevent moisture from entering the substation box 1 with the air flow, so that the air inside the substation box 1 remains dry. At the same time, the protective frame 314 covers and clings to the surface of the storage box 305, supports and limits the storage box 305, so that it clings to the surface of the ventilation hole 301 to prevent it from shaking and tilting, and the rainproof inclined plate 315 covers one side of the storage box 305 to prevent rainwater from entering the storage box 305.

[0061] The block silica gel desiccant 306 continuously absorbs moisture, and its own weight changes accordingly. The weight continues to increase, and the pressure on the extrusion long plate 312 and the weighing sensor 311 also changes accordingly, and then the state of the block silica gel desiccant 306 is monitored. After its weight increases to a certain extent, and the external sunlight shines on the condenser 415 on the top of the fixed cylinder 412, the condenser 415 plays a role of focusing light, and its light shines on the heat conducting plate 416, and the heat is transferred downward. The heat expansion pad 417 expands under the influence of the heat, and squeezes the extrusion block 418 and the pressure sensor 413 downward. By monitoring the pressure it feels, the intensity of sunlight in the external environment is detected, and then it is selected whether to adjust the position of the storage box 305. If the sunlight is good and the weight of the block silica gel desiccant 306 increases, the block silica gel desiccant 306 can be selected to be spread out and dried;

[0062] The electric telescopic rod 319 is started to retract downward, and the electric telescopic rod 319 pulls the lifting rack 320 and the connecting frame 321 downward. First, before the lifting rack 320 is not engaged with the rotating gear 310, the driving rack 322 is lowered, and the limit strip 323 slides along the limit frame 324. The driving rack 322 is engaged with the reversing gear 326, and the reversing gear 326 is engaged with the driving gear 327, driving the driving gear 327 to rotate, and the driving extension rod 328 rotates therewith, which contacts with the driving convex rod 318, pushing the driving convex rod 318 and the rotating disk 317 to rotate, and the rotating disk 31 7 and the rotating rod 316 rotate, driving the rotating seat 313 and the protective frame 314 to rotate, so that they gradually move away from the storage box 305. Then, the lifting rack 320 continues to descend and meshes with the rotating gear 310, driving the rotating gear 310 and the connecting rod 309 to rotate, so that the storage box 305 and the rotating block 304 rotate, and the storage box 305 gradually unfolds to a horizontal state, and the intercepting bar 307 faces upward. The protective frame 314 will pull the focusing convex lens 409 to move together, so that the focusing convex lens 409 moves to the top of the storage box 305. The sunlight shines on the top of the focusing convex lens 409. After its focusing effect, The light is then irradiated on the surface of the interception strip 307 and the block silica gel desiccant 306, and the block silica gel desiccant 306 is dried by focusing light, thereby removing the moisture absorbed by the block silica gel desiccant 306, improving the dryness of the block silica gel desiccant 306, and making it convenient for subsequent reuse. The concentrated light improves the drying efficiency. After drying for a period of time, the electric telescopic rod 319 extends upward, pushing the lifting rack 320 and the driving rack 322 to rise, driving the rotating gear 310 and the driving gear 327 to rotate, and driving the extension rod 328 to push the rotating disk 317 and the protective frame 314. Rotate, the rotating gear 310 also rotates with the storage box 305, the storage box 305 returns to the vertical state, covers the ventilation hole 301, and the protection frame 314 is pressed tightly against the surface of the storage box 305, and the focusing convex lens 409 returns to its original position and is pushed and embedded into the inside of the substation box 1 again, and the cleaning pad 411 slides closely against the surface of the focusing convex lens 409 to clean its surface until the lifting rack 320 is no longer engaged with the rotating gear 310, so that in subsequent adjustments, the protection frame 314 is first away from the storage box 305, and the storage box 305 is then rotated and adjusted, leaving a certain amount of moving space;

[0063] When the weather is hot and the sun is shining directly, the spliced ​​sunshade 404 is spliced ​​and fitted with the installation frame 402 to cover the light-transmitting glass 401, so that the outside sunlight will not directly shine into the inside of the substation box 1. In cold weather, the temperature is too low and the electrical components inside the substation box 1 cannot operate normally. It is necessary to use a temperature control mechanism to adjust the internal temperature. When there is sunlight during the day, the sunlight shines on the condenser 415, and the pressure sensor 413 feels a certain pressure, and starts and controls the drive motor 407, driving the rotating column 403 and the rotating gear 405 to rotate, and meshing with the rotating gear 405 on the other side, so that the spliced ​​sunshade 404 rotates and unfolds outward, revealing the light-transmitting glass 401, and using sunlight to pass through the light-transmitting glass 401 and shine on the inside of the substation box 1. The sealed space is exposed to the hot sunlight, which can increase the internal temperature to a certain extent, reduce the operation of the temperature control mechanism inside the substation box 1, and play a certain role in saving energy.
