[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , the present invention provides a technical solution: a portable and highly waterproof protection box for transformers, including: an outer box body 1, a cover plate 2, a lock 3, a connecting block 4, a block 5, a driving block 6, a rack 7, a gear 8, a sealing plate 9, a sealing ring 10, a water storage box 11, an absorbent material 12, a placing plate 13, a support rod 14, a fixed rod 15, a slide block 16, a spring 17, an inner installation frame 18, an elastic telescopic rod 19, a support plate 20, a first installation block 21, a threaded rod 22, a second installation block 23, a slide rod 24 and a towing rod 25.

[0030] When using this portable and highly waterproof protection box for transformers, first as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, the cover plate 2 is rotatably connected to the upper end of the outer box body 1, and the cover plate 2 is stuck outside the sealing plate 9 and the sealing ring 10, and the rotating shaft of the cover plate 2 is connected to the outer box body 1 through a torsion spring. The lock 3 is fixedly installed in the middle of the right end of the cover plate 2, and the lock 3 is snap-fitted inside the connecting block 4, and the connecting block 4 is fixedly installed at the upper right end of the outer box body 1. The block 5 is slidably connected to the inside of the upper right end of the outer box body 1, and the upper part of the driving block 6 is slidably connected to the inclined through groove formed inside the block 5, and the block 5 is movably engaged with the groove formed inside the lock 3. The lower end of the driving block 6 is fixedly connected to the upper end of the rack 7, and the front side of the rack 7 is meshed and driven with the gear 8, and the central shaft of the gear 8 is connected to the outer box body 1 through a torsion spring;

[0031] When it is necessary to open the cover plate 2, rotate the block at the right end of the central axis of the gear 8 so that the rack 7 is driven to move downward. The torsion spring connected to the gear 8 undergoes elastic deformation. When the rack 7 drives the driving block 6 to move downward, the driving block 6 slides inside the clamping block 5, causing the clamping block 5 to move leftward. The clamping block 5 stops engaging with the locking latch 3. The torsion spring outside the rotating shaft of the cover plate 2 restores its elasticity, causing the cover plate 2 to rotate and open. The locking latch 3 leaves the inside of the clamping block 5. When closing the cover plate 2, press the cover plate 2 so that the locking latch 3 snaps into the inside of the clamping block 5. When the locking latch 3 moves downward, it presses the inclined surface of the clamping block 5, causing it to move leftward. Through the transmission of the driving block 6, the rack 7, and the gear 8, the torsion spring outside the gear 8 undergoes elastic deformation. When the groove of the clamping block 5 and the locking latch 3 are at the same horizontal line, the torsion spring restores its elastic deformation and pushes the clamping block 5 into the inside of the locking latch 3, completing the fixation of the cover plate 2 and the outer box body 1. The operation method is simple and fast;

[0032] The sealing plate 9 is fixedly installed inside the upper end of the outer box body 1. A sealing ring 10 is fixedly installed on the outer side of the upper section of the sealing plate 9. A water storage box 11 is arranged below the sealing plate 9. The water storage box 11 is fixedly connected to the inner side wall of the outer box body 1. An absorbent material 12 is arranged inside the water storage box 11. The cover plate 2 is stuck outside the sealing plate 9 and the sealing ring 10;

[0033] When the cover plate 2 is closed, the cover plate 2 covers the outside of the sealing plate 9 and the sealing ring 10. When there is water on the outside of the cover plate 2 and the outer box body 1, the sealing ring 10 effectively prevents water from seeping in through the gap between the outer box body 1 and the cover plate 2. The upper section of the sealing plate 9 protrudes from the outer box body 1, further preventing water from entering the inside of the outer box body 1. When opening the cover plate 2, the water droplets attached to the cover plate 2 slide and converge on the left side of the cover plate 2. If water enters the inside of the outer box body 1, the water flows into the water storage box 11 and is adsorbed by the absorbent material 12. The replacement method of the absorbent material 12 is simple, preventing water from flowing into the inside of the outer box body 1 and damaging the sensor, and improving the waterproof performance of the protective box.

[0034] As Figure 1 、 Figure 2 、 Figure 3 and Figure 5 shown, the placement plate 13 is slidably installed inside the inner installation frame 18. The lower end of the inner installation frame 18 is fixedly connected to the inner side of the lower end of the outer box body 1. The outer side of the inner installation frame 18 is connected to the inner side wall of the outer box body 1 through an elastic telescopic rod 19. The fixing rods 15 are respectively fixedly installed at the lower end of the placement plate 13 and the lower end of the outer box body 1. A slider 16 is slidably connected to the outer side of the fixing rod 15. A spring 17 is sleeved on the outer side of the fixing rod 15. The two ends of the spring 17 are respectively fixedly connected to the fixing rod 15 and the slider 16. The support rod 14 is installed between the placement plate 13 and the outer box body 1. The upper and lower ends of the support rod 14 are respectively rotatably connected to the slider 16;

[0035] Place the sensor above the mounting plate 13. At this time, the mounting plate 13 moves downward under the weight it bears, and the support rod 14 is pressed and deformed, causing the slider 16 to move outward along the fixed rod 15. The spring 17 is pulled and elastically deformed, improving the stability when the sensor moves downward. Moreover, when removing the sensor, the spring 17 restores its elastic deformation and pushes the slider 16 outward, and the support rod 14 gradually unfolds to provide an auxiliary thrust for the upward movement of the mounting plate 13, facilitating the saving of the energy consumed in removing the sensor. When the protective box is in use, the elastic action of the elastic telescopic rod 19 protects the safety of the sensor in the inner installation frame 18;

[0036] The support plate 20 is slidably connected to the outer side of the lower end of the outer box body 1. The left and right ends of the support plate 20 are respectively fixedly installed with a first mounting block 21 and a second mounting block 23, and the first mounting block 21 is installed inside the second mounting block 23. The threaded rod 22 is rotatably connected inside the first mounting block 21 and is rotatably connected to the convex block at the lower section of the outer box body 1. The upper end of the sliding rod 24 is fixedly connected to the outer box body 1, and the second mounting block 23 is slidably connected to the outside of the sliding rod 24. The traction rod 25 is installed on the left side of the outer box body 1, and the traction rod 25 has a telescopic structure;

[0037] When the protective box is in use, the support plate 20 descends to contact the ground, and the pulley at the lower end of the outer box body 1 leaves the contact with the ground. When it is necessary to move the protective box, rotate the threaded rod 22 so that the first mounting block 21 drives the support plate 20 to move upward. The support plate 20 gradually leaves the contact with the ground and moves to the lower end of the outer box body 1. The second mounting block 23 slides on the outside of the sliding rod 24 to ensure the stability of the movement of the support plate 20. The pulley recontacts the ground. Pull the traction rod 25 upward to make it unfold, and use the pulley to simply and quickly move the protective box by pulling the traction rod 25.

[0038] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. In addition, the directional nouns such as up, down, left, right, front, and back in the text only represent their relative positions rather than absolute positions.
