One end of a first mainspring 304 and a second mainspring 3041 are installed on the rotating shaft 302, and the other ends of the first mainspring 304 and the second mainspring 3041 are connected to the U-shaped shell 3, a rectangular frame 4 is fixedly connected to one of the U-shaped shells 3 and is connected to the U-shaped shell 3, an elastic sliding plate 401 is slidably connected in the rectangular frame 4, a first absorbent cotton 402 is installed between the rectangular frame 4 and the elastic sliding plate 401, a segmented rack frame 403 is fixedly connected to the bottom of the elastic sliding plate 401, a limiting mechanism is provided on the first rotating shaft 301, the limiting mechanism is used to limit the winding of the sealing cloth 303, the first absorbent cotton 402 is used to absorb moisture and expand to move the segmented rack frame 403 downward, the segmented rack frame 403 is used to unlock the limiting mechanism to release the sealing cloth 303 to seal the cabinet 1 to prevent rainwater from entering the cabinet 1, and a wiping mechanism is provided in the cabinet 1 to wipe the moisture inside the cabinet 1.

[0032] like Figure 3-Figure 4 As shown, the limiting mechanism includes a first limiting wheel 5, and the first limiting wheel 5 is fixedly connected to one end of the first rotating shaft 301, wherein a first latch tooth 501 is slidably connected in one U-shaped shell 3, and a first elastic member is connected between the first latch tooth 501 and the U-shaped shell 3, and the first latch tooth 501 engages with the first limiting wheel 5 to limit the rotation of the first limiting wheel 5, and the first limiting wheel 5 is used in conjunction with the segmented rack frame 403.

[0033] like Figure 3-Figure 4 As shown, the limiting mechanism also includes a tilting frame 4031, and the tilting frame 4031 is fixedly connected to one side of the segmented rack frame 403, and a through hole is opened at the bottom of one U-shaped shell 3. When the segmented rack frame 403 and the tilting frame 4031 move, they penetrate the through hole at the bottom of the U-shaped shell 3, and a fixed frame 502 is fixedly connected to one side of the first latch tooth 501. The tilting frame 4031 is used to squeeze the fixed frame 502 to make the first latch tooth 501 disengage from the first limiting wheel 5. After the first limiting wheel 5 is disengaged from the restriction, the second spring 3041 is released and drives the first rotating shaft 301 to rotate.

[0034] In the initial state, the sealing cloth 303 is in a rolled-up state on the second rotating shaft 302, and the first spring 304 is in a released state. At this time, the sealing cloth 303 does not seal the cabinet 1, and the vent 101 of the cabinet 1 is in a connected state with the strip-shaped opening of the base 2, which effectively ensures the ventilation and drying effect of the power equipment on the base 2. When the outside wind passes through the vent 101, the exhaust fan 103 will rotate, and the wind force generated by the rotation of the exhaust fan 103 will blow toward the strip-shaped opening on the base 2, further ventilating the power equipment on the base 2. The second spring 3041 on the first rotating shaft 301 is in a power storage and contraction state. At this time, the first latch 501 limits the first limiting When moisture or rain occurs, the first absorbent cotton 402 in the rectangular frame 4 will absorb the moisture or rainwater contained in the moisture, so that the first absorbent cotton 402 expands and extends in the rectangular frame 4. After the first absorbent cotton 402 expands and extends, it squeezes the elastic sliding plate 401 and slides downward along the rectangular frame 4, so that the segmented rack frame 403 moves downward and drives the inclined frame 4031 to move downward synchronously. When the segmented rack frame 403 and the inclined frame 4031 move, they penetrate the through hole at the bottom of the U-shaped shell 3. At this time, the inclined frame 4031 moves downward and squeezes the fixed frame 502 to move. The fixed frame 502 drives the first clamping tooth 501 to move in the U-shaped shell 3 and compresses the first elastic The first latching tooth 501 moves away from the first limiting wheel 5. After the first limiting wheel 5 cancels the restriction, the second spring 3041 is released. After the second spring 3041 is released, the first rotating shaft 301 is driven to rotate, so that the first rotating shaft 301 rotates to rewind the sealing cloth 303. At this time, the sealing cloth 303 slides along the bottom of the cabinet 1 to seal the cabinet 1 to prevent moisture or rain from entering the cabinet 1. At this time, the temperature generated by the power equipment in the cabinet 1 is discharged outward through the exhaust valve 102, and the dryness and humidity inside the cabinet 1 are effectively solved. At the same time, when the first rotating shaft 301 rewinds the sealing cloth 303, the second rotating shaft 302 rotates, and the second rotating shaft 302 rotates to drive the first rotating shaft 301 to rotate to rewind the sealing cloth 303. The clockwork spring 304 generates stored force, and at the same time, the first absorbent cotton 402 continues to expand and extend and drives the segmented rack 403 to continue to move downward. When the segmented rack 403 engages with the first limiting wheel 5, the segmented rack 403 further drives the first limiting wheel 5 to rotate, so that the first rotating shaft 301 continues to rotate to reel in the sealing cloth 303. At this time, the second rotating shaft 302 continues to rotate to make the first clockwork spring 304 further store force. When the first absorbent cotton 402 expands and extends to the maximum value, the segmented rack 403 engages with the first limiting wheel 5 and is in a stationary state. At the same time, the sealing cloth 303 has sealed the cabinet 1 to prevent moisture or rainwater from entering the interior of the cabinet 1.

[0035] When the sun shines on the first absorbent cotton 402 in the rectangular frame 4, the moisture absorbed by the first absorbent cotton 402 is dissipated, and at the same time, the first absorbent cotton 402 is reset. When the first absorbent cotton 402 is reset, the elastic sliding plate 401 drives the segmented rack 403 and the tilting frame 4031 to move upward and reset. At this time, the segmented rack 403 is disengaged from the first limiting wheel 5, and the first spring 304 on the second rotating shaft 302 is released and drives the second rotating shaft 302 to rotate. The second rotating shaft 302 also rolls up the sealing cloth 303. When the first rotating shaft 301 rotates, it will drive the second mainspring 3041 to generate stored force, so that the first absorbent cotton 402 continues to reset and moves, driving the segmented rack frame 403 and the tilting frame 4031 to continue to move upward and reset. At the same time, after the tilting frame 4031 resets upward, it no longer squeezes the fixed frame 502, and the first elastic member drives the first latch tooth 501 to reset, and the first latch tooth 501 is engaged with the first limiting wheel 5 to limit the position. The first latch tooth 501 resets and engages with the first limiting wheel 5 to ensure the stored force and contraction state of the second mainspring 3041, and can effectively prevent the cabinet 1 from being damp according to weather conditions.

[0043] like Figure 7-Figure 8 As shown, it also includes a one-way gear 21. One side of the second E-shaped frame 11 is rotatably connected to the one-way gear 21. A rack 211 is fixedly connected to the moving frame 7. The one-way gear 21 and the rack 211 are used in conjunction with each other.

[0044] When there is a temperature difference in the weather, it is more humid in the morning and evening, and the second absorbent cotton 6 inside the base 2 will absorb the moisture contained in the moisture. At this time, due to the temperature difference in the climate, the inner wall of the cabinet 1 will become humid. When the humidity is serious, it will affect the operation of the electrical equipment inside the cabinet 1. When the second absorbent cotton 6 absorbs the moisture contained in the moisture, it will expand and extend. The second absorbent cotton 6 expands and extends to squeeze the movable frame 7. The movable frame 7 is forced to move upward to squeeze the wedge-shaped groove of the sliding frame 16, so that the sliding frame 16 slides to one side along the T-shaped frame 14. At the same time, the sliding frame 16 drives the second magnet 15 to move away from the first magnet 901. At this time, the third spring 801 is in a released state. The movement of the sliding frame 16 will squeeze the L-shaped rod 17 to move, and the L-shaped rod 17 moves and drives the second latch 1 71 and the extrusion frame 18 move synchronously, and at the same time, the L-shaped rod 17 squeezes the third elastic member, and the second latch tooth 171 disengages from the second limiting wheel 803 when moving. At this time, the extrusion frame 18 squeezes the wedge-shaped seat 191 during the movement, and the wedge-shaped seat 191 is forced to squeeze the tilting seat 19 to slide on the support frame 141 and compress the fourth elastic member. When the extrusion frame 18 moves over the wedge-shaped seat 191, the fourth elastic member drives the tilting seat 19 and the wedge seat 191 to reset, and the wedge seat 191 limits the extrusion frame 18, the L-shaped rod 17 and the second latch tooth 171 to reset. After the second limiting wheel 803 is not restricted, the first E-shaped frame 9 moves downward and drives the rope 802 to release, so that the rope 802 drives the third shaft 8 to rotate when it is released downward, and the third shaft 8 drives the third spring 801 to rotate After accumulating force, the first E-shaped frame 9 drives the second E-shaped frame 11 to move downward along the inner wall of the cabinet 1 through the elastic rod 10. When the second E-shaped frame 11 moves downward, the damp water contained in the inner wall of the cabinet 1 is scraped off by the scraping strip 111. The excess water will flow downward along the inner wall of the cabinet 1 and flow into the bottom of the cabinet 1 through the drainage groove 201. The water inside the cabinet 1 flows out through the drainage port on the rear side of the cabinet 1. At the same time, the wiping cloth 13 wipes the scraped inner wall of the cabinet 1 to keep it dry. When the second E-shaped frame 11 moves downward and drives the one-way gear 21 to contact and mesh with the rack 211, the one-way gear 21 is in idling at this time, and the first E-shaped frame 9 continues to drive the second E-shaped frame 11 to move downward along the inner wall of the cabinet 1 through the elastic rod 10. When the cabinet 1 is at the bottom, the first E-shaped frame 9 squeezes the first hinge plate 12 by moving downward with a buffer force, and the first hinge plate 12 drives the L-shaped frame 121 and the sliding shaft 122 to move downward, and at the same time, the sliding shaft 122 slides along the curved track frame 124, thereby driving the first hinge plate 12 to rotate at the hinge of the first E-shaped frame 9, and at the same time, the first E-shaped frame 9 slides along the elastic rod 10 and approaches the second E-shaped frame 11. At this time, the second E-shaped frame 11 is at the bottom of the cabinet 1 and is above the drainage groove 201. When the first hinge plate 12 rotates, the sliding shaft 122 slides to the end along the curved track frame 124. At this time, the sliding shaft 122 drives the curved track frame 124 to rotate, and as the curved track frame 124 rotates, it drives the second hinge plate 123 to rotate at the hinge of the second E-shaped frame 11.At this time, the L-shaped frame 121 and the curved track frame 124 follow the first hinge plate 12 and the second hinge plate 123 to rotate in a horizontal state. At the same time, the first hinge plate 12 and the second hinge plate 123 squeeze the moisture inside the wiping cloth 13, and the excess moisture is discharged along the drainage groove 201 so that the moisture flows out through the drainage port on the rear side of the cabinet 1. At this time, the third spring 801 releases the stored force, thereby driving the third rotating shaft 8 to rotate and reeling the rope 802. The rope 802 drives the first E-shaped frame 9, the elastic rod 10 and the second E-shaped frame 11 to reset. At the same time, the first hinge plate 12 and the second hinge plate 123 drive the wiping cloth 13 to reset. At the same time, the second E-shaped frame 11 moves upward to reset and drives the one-way gear 21 to contact and mesh with the rack 211. At this time, the one-way gear 21 rotates and drives the rack 211 to move downward. The rack 211 moves downward and drives the moving frame 7 to squeeze the moisture inside the second absorbent cotton 6 downward. The excess moisture flows into the cabinet 1 through the drainage port from the grid-like rectangular groove in the base 2. The second elastic member drives the sliding frame 16 to reset, and the sliding frame 16 synchronously drives the second magnet 15 to reset. At this time, the first E-shaped frame 9 drives the first magnet 901 to move upward, and the second magnet 15 and the first magnet 901 will generate magnetic force, further driving the first E-shaped frame 9 to reset. At the same time, the first E-shaped frame 9 squeezes the wedge block 2001 when it is reset, and the wedge block 2001 drives the Z-shaped frame 20 to slide along the E-shaped rod 142. When the Z-shaped frame 20 moves, it squeezes the inclined seat 19. The inclined seat 19 is forced to drive the wedge seat 191 to slide along the support frame 141 and compress the fourth elastic member. The wedge seat 191 is separated from the extrusion frame 18. At this time, the third elastic member is reset and drives the L-shaped rod 17, the second latch tooth 171 and the extrusion frame 18 to reset. The second latch tooth 171 is reset and engages with the second limiting wheel 803 to limit the rotation of the third rotating shaft 8. At this time, the rope 802 drives the first E-shaped frame 9 to reset. ,
