This application is convenient for providing buffering for the transformer when the installation box encounters external force, improving the stability of the transformer installation, and has strong practicality.

[0004] With respect to the above-mentioned related technologies, the buffer block and the buffer spring are arranged so that when the transformer bumps up and down, the supporting plate moves downward so that the second rotating shaft abuts against the bottom end of the storage box and slides, and at the same time the buffer spring is pulled up to reduce the amplitude of the up and down bumping of the supporting plate, thereby reducing the amplitude of the up and down bumping of the transformer and providing a buffering effect. However, a dehumidification structure is provided inside the transformer, resulting in the transformer itself not having a dehumidification function. When the humidity inside the transformer is heavy, the components inside the transformer may be damaged due to the moisture, which is not conducive to protecting the transformer.

[0006] By adopting the above technical solution, when the equipment is used, the staff connects the mounting plate to the transformer body through the first bolt. When the moisture inside the transformer body is heavy, suction is generated by the exhaust fan, so that the moisture inside the transformer body enters the drying box through the exhaust pipe. The drying box is provided with a dehumidification component, which can absorb moisture and then dehumidify. The drying box and the cover plate are fixed by the second bolt, which is convenient for the staff to open the cover plate to replace the drying component, which is beneficial to maintaining the drying effect of the equipment. The gas that removes moisture enters the first protective box through the connecting pipe and the conduit. The first protective box is provided with a heating component, which plays the role of drying the gas, so as to achieve the effect of removing moisture again. The gas that removes water vapor enters the transformer body through the return air pipe under the wind drive of the exhaust fan, and the gas acts on the surface of the internal components of the transformer body, which can remove the moisture inside the transformer body and dry the components, which is beneficial to improve the dehumidification effect of the equipment and reduce the phenomenon that the internal components of the transformer body are damaged due to excessive moisture.

[0007] When the humidity and heat inside the transformer body are too high, the heating component stops running, and then generates cold air through the refrigeration guide component. The cold air enters the first protective box through the branch pipe, and then the cold air enters the transformer body through the return air pipe under the action of the exhaust fan, which can play a role in heat dissipation. The heat inside the transformer body enters the first protective box through the conduit and combines with the cold air to achieve the effect of cooling, and reduces the diffusion of the cold air, which is beneficial to maintain the heat dissipation effect of the equipment, enabling the equipment to dehumidify and play a role in heat dissipation.

[0008] The top of the transformer body is provided with a protective plate to provide shade and shelter from rain, which helps prevent rain from entering the inside of the transformer body. When the protective plate needs to be installed, the staff will place the protective plate above the transformer body so that the block installed at the bottom of the column is placed in the slot opened at the top of the mounting block on the same side. The protective plate can be fixed by the cooperation of the block and the slot, and a limit assembly is provided in the slot to limit the fixed block, which is beneficial to maintain the stability of the installation of the protective plate.

[0009] Furthermore, the dehumidification component includes a water-absorbing cotton layer, an activated carbon layer, a bamboo charcoal layer and a desiccant layer which are slidably installed in the drying box, and first sliders are fixedly installed on both sides of the water-absorbing cotton layer, the activated carbon layer, the bamboo charcoal layer and the desiccant layer. The inner wall of the drying box is provided with a first sliding groove which matches the first slider on the same side, a sealing gasket is fixedly installed on the cover plate close to the side of the drying box, and the second bolt is fixedly installed with two symmetrically distributed toggle rods on the side wall away from the drying box.

[0010] By adopting the above technical scheme, the moisture inside the transformer body is sucked into the drying box through the exhaust fan, and the water-absorbing cotton layer, the activated carbon layer, the bamboo charcoal layer and the desiccant layer are slidably installed in the drying box. The gas with moisture is filtered through the water-absorbing cotton layer, the activated carbon layer, the bamboo charcoal layer and the desiccant layer layer by layer, which can play a role in removing moisture. The water-absorbing cotton layer, the activated carbon layer, the bamboo charcoal layer and the desiccant layer are clamped and fixed by the first sliding block and the first sliding groove provided on the inner wall of the drying box, which is convenient for the staff to disassemble and replace, and is conducive to maintaining the dehumidification effect of the equipment.

[0011] Furthermore, the heating assembly includes a plurality of heating wires arranged in a first protective box, protective cotton is fixedly installed in the first protective box, a support frame is fixedly installed in the first protective box, and a guide fan is provided in the support frame.

[0012] By adopting the above technical solution, heat is generated by the heating wire, and then wind is generated by the guide fan. The wind drives the heat into the transformer body through the return air pipe, which can play a drying role and achieve a further dehumidification effect. The gas after preliminary dehumidification enters the first protective box and is baked by the heat generated by the heating wire to further remove water vapor, which is conducive to maintaining the subsequent drying effect.

[0013] Furthermore, the refrigeration guide assembly includes a support plate fixedly installed in the second protective box, a reduction motor is fixedly installed on one side of the support plate, a fan blade is fixedly sleeved on the side wall of the output shaft of the reduction motor, and the fan blade is located in the wind collecting scoop, and a plurality of semiconductor refrigeration plates distributed in a linear array are fixedly installed on the inner wall of the top end of the second protective box, and the top ends of the semiconductor refrigeration plates all pass through the second protective box.

[0014] By adopting the above technical solution, when the heat inside the transformer body is too high, cold air is generated by the semiconductor refrigeration plate, and then the fan blades are driven by the reduction motor to rotate to generate wind force. The wind force drives the cold air to enter the first protective box through the branch pipe, and then enter the transformer body driven by the guide fan and the exhaust fan, which can play a role in cooling. The moisture and heat inside the transformer body are extracted by the exhaust fan, and after purification and dehumidification, they enter the first protective box and combine with the cold air to achieve a cooling effect. The cooled gas enters the transformer body to play a role in heat dissipation, which is beneficial to reduce the loss of cold air, so that the equipment has both dehumidification and cooling functions.

[0015] Furthermore, a protective frame is fixedly installed on the top of the second protective box, heat dissipation holes distributed in a linear array are opened on both sides of the protective frame, rain shields are fixedly installed on both sides of the protective frame, and the semiconductor refrigeration plate passes through one end of the second protective box and is located in the protective frame.

[0016] By adopting the above technical solution, a protective frame is provided on the top of the second protective box, and the top of the semiconductor refrigeration plate is located in the protective frame, which can play a role in protecting the semiconductor refrigeration plate. The end of the semiconductor refrigeration plate located in the protective frame is the heating end, which is beneficial to maintaining the cooling effect of the equipment. The heat dissipation holes opened on the side wall of the protective frame facilitate the dissipation of heat.

[0017] Furthermore, a support rod is rotatably installed in the branch pipe, and a plurality of baffles distributed in a ring array are fixedly installed on the side wall of the support rod.

[0018] By adopting the above technical solution, the support rod and the baffle are arranged inside the branch pipe to block the branch pipe, which helps to prevent heat from entering the second protective box. The cold air blows the baffle to rotate with the support rod to facilitate the cold air to enter the first protective box, and the support rod can only rotate in one direction due to the existing technical structure, which facilitates the cold air to enter the first protective box stably, which is beneficial to maintain the cooling effect of the equipment.

[0019] Furthermore, the dustproof component includes a frame fixedly installed on the side of the second protective box away from the first protective box, an installation frame is slidably installed in the frame, dustproof cotton is fixedly installed in the installation frame, second sliders are fixedly installed on the top and bottom ends of the installation frame, and second sliding grooves matching the second slider on the same side are provided on the top inner wall and the bottom inner wall of the frame. A plurality of plug rods distributed in a linear array are fixedly installed on the side of the installation frame close to the transformer body, and a slot matching the plug rods is provided on the inner wall of the frame away from the transformer body.

[0020] By adopting the above technical solution, when the fan blades rotate to generate wind, negative pressure is generated in the second protective box, thereby allowing outside air to enter through the through hole opened in the side wall of the second protective box. The side wall of the second protective box is provided with dust-proof cotton, which plays a role in removing dust in the air, helps to prevent dust from entering the inside of the transformer body, and achieves a dust-proof effect. The dust-proof cotton is fixed by the second slider and the second slide groove opened in the inner wall of the frame, which is convenient for the staff to disassemble and clean it later, and is beneficial to maintaining the dust-proof effect of the equipment. When the installation frame is located inside the frame and slides, the plug rod installed at the end of the installation frame is engaged with the slot opened in the inner wall of the frame, which is beneficial to maintaining the stability of the dust-proof cotton installation.

[0021] Furthermore, the limit assembly includes a limit rod slidably installed in the movable groove, a spring is fixedly installed between the opposite ends of the two limit rods on the same side and the inner wall on the side opposite to the movable groove on the same side, limit grooves matching the limit rods on the same side are opened on both sides of the clamping block, a stabilizing rod is fixedly installed on the inner wall of the bottom end of the clamping groove, and grooves matching the clamping blocks on the same side are opened at the bottom ends of the two clamping blocks.

[0022] By adopting the above technical scheme, when the card block slides into the card slot on the same side, a stabilizing rod is provided on the inner wall of the top of the card slot, and the stabilizing rod is engaged with the groove opened at the bottom of the card block. The cooperation of the stabilizing rod and the groove is conducive to maintaining the stability of the engagement between the card block and the card slot, and when the card block slides into the card slot on the same side, the card block pushes the limiting rod on the same side to slide in the movable groove on the same side, and the limiting rod pushes the spring on the same side to contract. When the card block is completely engaged with the card slot on the same side, the limiting rod returns to its original position under the elastic force of the spring on the same side, and the end of the limiting rod is engaged with the limiting groove opened on the opposite side of the card block on the same side, which can play the role of positioning and stabilizing the card block, which is conducive to maintaining the stability of the installation of the protective plate and is convenient for subsequent disassembly.

[0023] Furthermore, two symmetrically distributed support blocks are fixedly mounted on the side walls at opposite ends of the two limit rods on the same side, and support grooves matching the support blocks on the same side are formed on the inner wall of the movable groove.

[0024] By adopting the above technical solution, when the limit rod slides in the movable groove on the same side, the limit rod slides with the support block in the support groove on the same side. The cooperation between the support block and the support groove is conducive to maintaining the sliding stability of the limit rod and helps to prevent the limit rod from leaving the movable groove.

[0025] Furthermore, four symmetrically distributed positioning blocks are fixedly mounted on one side of the transformer body close to the mounting plate, and positioning holes matching the positioning blocks are formed on one side of the mounting plate close to the transformer body.

[0026] By adopting the above technical solution, a positioning block is provided on the side wall of the transformer body. When setting the mounting plate, the staff places the mounting plate on one side of the transformer body so that the positioning block engages with the positioning hole opened on the side wall of the mounting plate, thereby positioning and stabilizing the mounting plate, making it easier for the staff to stabilize the mounting plate later.

[0027] In summary, the present invention includes the following beneficial technical effects: (1) In the present invention, the exhaust fan and the dehumidification component cooperate to remove moisture from the transformer body, and the heating component is set so that the dried gas blows hot air into the transformer body to dry the internal components of the transformer body, which helps to avoid damage to the internal components of the transformer body due to moisture. By setting the exhaust fan, the dehumidification component and the heating component, the device has the functions of dehumidification and drying, thereby protecting the internal components of the transformer body.

[0028] (2) In the present invention, by setting up the refrigeration guide component, cold air is generated by the semiconductor refrigeration plate, and then the fan blades are driven by the reduction motor to generate wind force. The wind force drives the cold air to enter the first protective box through the branch pipe, and then enter the inside of the transformer body under the blowing of the exhaust fan. The hot air inside the transformer enters the first protective box through the conduit and combines with the cold air to achieve the effect of circulating refrigeration, which is beneficial to maintaining the heat dissipation efficiency of the equipment and reducing the waste of cold air, so that the equipment has both dehumidification function and heat dissipation function.

[0043] The top of the transformer body 1 is provided with a protective plate 2 to provide sunshade and rain protection, which helps to prevent rainwater from entering the inside of the transformer body 1. When the protective plate 2 needs to be installed, the staff will place the protective plate 2 above the transformer body 1, so that the block 5 installed at the bottom of the column 3 is placed in the slot 31 opened at the top of the mounting block 6 on the same side. The protective plate 2 can be fixed by the cooperation of the block 5 and the slot 31. When the block 5 slides into the slot 31 on the same side, a stabilizing rod 32 is provided on the inner wall of the top of the slot 31. The stabilizing rod 32 is engaged with the groove opened at the bottom of the block 5. The cooperation between 2 and the groove is conducive to maintaining the stability of the engagement between the block 5 and the slot 31, and when the block 5 slides into the slot 31 on the same side, the block 5 pushes the limiting rod 30 on the same side to slide in the movable slot 28 on the same side, and the limiting rod 30 pushes the spring 29 on the same side to contract. When the block 5 is completely engaged with the slot 31 on the same side, the limiting rod 30 returns to its original position under the elastic force of the spring 29 on the same side, and the end of the limiting rod 30 is engaged with the limiting groove opened on the opposite side of the block 5 on the same side, which can play the role of positioning and stabilizing the block 5, which is conducive to maintaining the stability of the installation of the protective plate 2 and is convenient for subsequent disassembly.

[0044] Two symmetrically distributed support blocks are fixedly installed on the side walls at the opposite ends of the two limit rods 30 on the same side, and the inner wall of the movable groove 28 is provided with a support groove matching the support block on the same side. When the limit rod 30 slides in the movable groove 28 on the same side, the limit rod 30 slides in the support groove on the same side with the support block. The cooperation between the support block and the support groove is conducive to maintaining the sliding stability of the limit rod 30 and helps to prevent the limit rod 30 from leaving the movable groove 28.

[0045] The implementation principle of the embodiment of the present invention is as follows: when the equipment is used, the staff connects the mounting plate 46 to the transformer body 1 through the first bolt 19. When the moisture inside the transformer body 1 is heavy, suction is generated by the exhaust fan 27, so that the moisture inside the transformer body 1 enters the drying box 7 through the exhaust pipe 4. The drying box 7 is provided with a dehumidification component, which can absorb moisture and then dehumidify. The gas that removes moisture enters the first protective box 12 through the connecting pipe 9 and the conduit 11. The first protective box 12 is provided with a heating component, which plays a role in drying the gas, thereby achieving the effect of removing moisture again. The gas that removes water vapor enters the transformer body 1 through the return air pipe 15 driven by the wind of the exhaust fan 27, and the gas acts on the surface of the internal components of the transformer body 1, which can remove the moisture inside the transformer body 1 and dry the components, which is beneficial to improving the dehumidification effect of the equipment and reducing the phenomenon that the internal components of the transformer body 1 are damaged due to excessive moisture.

[0046] When the humidity and heat inside the transformer body 1 are too high, the heating component stops running, and then generates cold air through the refrigeration guide component. The cold air enters the first protective box 12 through the branch pipe 39, and then the cold air enters the transformer body 1 through the return air pipe 15 under the action of the exhaust fan 27, which can play a role in heat dissipation. The heat inside the transformer body 1 enters the first protective box 12 through the conduit 11 and combines with the cold air to achieve a cooling effect and reduce the diffusion of the cold air, which is beneficial to maintaining the heat dissipation effect of the equipment, enabling the equipment to dehumidify and play a role in heat dissipation.

[0047] The top of the transformer body 1 is provided with a protective plate 2 to provide shade and shelter from rain, thereby helping to prevent rainwater from entering the inside of the transformer body 1. When the protective plate 2 needs to be installed, the staff places the protective plate 2 above the transformer body 1 so that the block 5 installed at the bottom of the column 3 is placed in the slot 31 opened at the top of the mounting block 6 on the same side. The protective plate 2 can be fixed by the cooperation of the block 5 and the slot 31. A limiting component is provided in the slot 31 to limit the fixing of the block 5, thereby facilitating the stability of the installation of the protective plate 2.

[0048] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
