Description

Technical Field

[0001] The present invention relates to the field of transformers, and in particular to an outdoor box-type transformer. Background Art

[0002] Outdoor box-type transformers need to have good sealing performance to prevent rain and dust from entering and affecting the internal body of the box-type transformer. However, due to the long-term influence of the sealant and the external environment, the sealant parts will age faster, leading to deterioration, cracking, deformation, and failure, which will reduce the sealing performance of the outdoor box-type transformer and make it impossible to protect the internal body from rain and dust.

[0003] For example, the Chinese invention patent (application number: CN111816408A) discloses an "outdoor transformer", and its specification discloses: waterproof transformers are generally provided with a special protective shell or cover, and the internal transformer is potted, which can cope with harsh environments such as high temperature, humidity, rain, and water immersion. It has a high IP protection level and has been widely used in outdoor lamps, urban lighting projects, mining areas and mines, ship equipment, electronic bathroom equipment, industrial atomizing humidifiers, medical equipment, precision instruments and other industries. When waterproof transformers are used outdoors, due to the large changes in environmental factors, they must have good heat dissipation performance. The existing waterproof transformers are sealed, and the heat dissipation performance is difficult to fully meet the environmental changes. Providing a transformer with both good waterproof performance and good heat dissipation performance is a trend in current technology research and development; the above patents can prove the existing defects.

[0018] Beneficial effects of the present invention:

[0019] In the scheme of this application:

[0020] 1. In order to solve the problem of decreased sealing due to aging of the sealing glue, the present application uses the aging of the sealing glue strip and the removal of the suction cup adsorption through the repair component set up, so that the screw roller can rotate under the action of the impeller 1, and the aged part of the sealing glue strip is cut, and the cutting part of the sealing glue strip is moved up by setting a push plate and a compression spring, and at the same time, the sealing plate squeezes the glue storage cavity, and the glue liquid inside the glue storage cavity is transported to the bottom of the push plate through the glue guide hole and the glue injection needle.

[0021] 2. In order to solve the problem of poor heat dissipation of the transformer during use, the present application uses a servo motor to drive the second impeller to rotate through the heat dissipation component, so that the hot air in the bottom box can be transported to the heat dissipation cavity. The hot air moves from the diverter groove to the assembly cavity, and then is collected by the wind collecting cover. The hot air can be transported to the assembly cavity through the bellows, thereby driving the first impeller to rotate, and the second impeller is driven to rotate in the opposite direction through the transmission shaft, so that the residence time of the hot air in the assembly cavity is increased. At the same time, the external air can circulate inside the transmission shaft through the hollow inside of the transmission shaft, thereby improving the cooling of the hot air and achieving effective cooling of the inside of the transformer;

[0022] 3. Through the setting of the lifting assembly, the bidirectional screw can be used to drive the screw sleeve to move closer, so that the main body can be lifted to the top of the bottom box through the receiving plate, which is convenient for maintenance personnel to carry out all-round inspection of the main body. At the same time, when the main body is lowered to the inside of the bottom box, the shock-absorbing ring can abut against the screw sleeve, and the slider can abut against the shock-absorbing plate. Under the action of the reset spring 1 and the reset spring 2, the main body can be shock-absorbing, thereby reducing the noise generated by the transformer during use.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0041] As described in the background technology, due to the long-term influence of the sealant and the external environment, the sealant will age faster, causing deterioration, cracking, deformation, and failure, which will reduce the sealing performance of the outdoor box-type transformer and make it impossible to protect the internal body from rain and dust.

[0042] In order to solve this technical problem, the present invention provides an outdoor box-type transformer, which is applied to a transformer.

[0043] Specifically, please refer to Figure 1-12 , the outdoor box-type transformer specifically includes:

[0044] A bottom box 1, a cover plate 101 is provided on the top of the bottom box 1, a main body 102 is provided inside the bottom box 1, a square placement groove 103 is provided at the joint between the top of the bottom box 1 and the bottom of the cover plate 101, a sealing strip is provided in the square placement groove 103, and the feature is that a repair component 2 is provided inside the cover plate 101, the repair component 2 and the square placement groove 103 are designed correspondingly, the repair component 2 is composed of a plurality of repair units 200, the repair unit 200 includes an assembly cavity 218 provided inside the cover plate 101, the repair unit 200 includes all structures inside the assembly cavity 218, an impeller 202 is rotatably installed in the assembly cavity 218, a plurality of glue storage cavities 201 are provided at the bottom of the assembly cavity 218, the glue storage cavities 201 and the repair unit 200 are designed correspondingly, a connecting shaft 203 is fixedly installed at the bottom of the impeller 202 and is located in the glue storage cavity 201, and the interior of the connecting shaft 203 is hollow;

[0045] A sealing plate 211 is piston-slidably installed in the glue storage cavity 201, and a screw roller 204 is rotatably installed at the bottom of the sealing plate 211. The bottom of the connecting shaft 203 and the top of the screw roller 204 are designed to be snap-connected. A glue injection needle 206 is provided at the bottom of the connecting shaft 203. The inside of the glue injection needle 206 is connected with the inside of the connecting shaft 203. A suction cup 208 is fixedly installed at the bottom of the screw roller 204 and can absorb the sealing rubber strip. A plurality of glue guide holes 215 are arranged in an array on the outer wall of the connecting shaft 203. Cutting blades 207 are snap-connected and installed on both sides of the screw roller 204. A plurality of push plates 209 are arranged in an array at the bottom of the placement groove 103. The push plates 209 and the repair unit 200 are designed to correspond to each other. A compression spring 210 is fixedly installed between the bottom of the push plate 209 and the bottom box 1.

[0046] A heat dissipation component 3 is provided inside the cover plate 101, and the heat dissipation component 3 is connected to the assembly cavity 218. When the suction cup 208 and the sealing strip are released from adsorption, the impeller 202 can be driven to rotate, thereby triggering the repair unit 200 to repair the sealing strip.

[0047] The outdoor box-type transformer provided by the present invention solves the problem that the long-term influence of the sealing glue and the external environment will cause the sealing glue parts to age faster, leading to deterioration, cracking, deformation, and thus failure, which reduces the sealing performance of the outdoor box-type transformer and makes it impossible to protect the internal body from rain and dust. The present application sets a repair component 2 and utilizes a plurality of repair units 200 to repair any part of the sealing glue strip separately. The suction cup 208 fixedly installed at the bottom of the screw roller 204 can form adsorption with the sealing glue strip, so that the impeller 202 cannot rotate under the action of the wind force generated by the heat dissipation component 3.

When the sealing strip is cut, the cutting portion of the sealing strip moves upward under the action of the push plate 209 and the compression spring 210, thereby squeezing and moving the screw roller 204 upward, and at the same time driving the sealing plate 211 upward to squeeze the inside of the glue storage cavity 201. At the same time, the glue injection needle 206 fixedly installed at the bottom of the connecting shaft 203 can pierce the sealing strip and pass through the push plate 209, and the glue in the glue storage cavity 201 is transported to the bottom of the push plate 209 through the glue guide hole 215 and the glue injection needle 206. The glue at the bottom of the push plate 209 will solidify due to the entry of air, thereby sealing the repaired part, and then any part of the sealing strip can be repaired separately to prevent the sealing strip from aging and failure, and unable to protect the internal body of the transformer from rain and dust.

[0052] A sealing plate 211 is piston-slidably installed in the glue storage cavity 201, and a screw roller 204 is rotatably installed at the bottom of the sealing plate 211. The bottom of the connecting shaft 203 and the top of the screw roller 204 are designed to be snap-connected. A glue injection needle 206 is provided at the bottom of the connecting shaft 203. The inside of the glue injection needle 206 is connected with the inside of the connecting shaft 203.

A plurality of push plates 209 are arranged in an array at the bottom of the placement groove 103. The push plates 209 and the repair unit 200 are designed to correspond to each other. A compression spring 210 is fixedly installed between the bottom of the push plate 209 and the bottom box 1.

[0053] The cover plate 101 is provided with a heat dissipation component 3 inside, and the heat dissipation component 3 is connected with the assembly cavity 218. When the suction cup 208 and the sealing strip are released from adsorption, the impeller 1 202 can be driven to rotate, thereby triggering the repair unit 200 to repair the sealing strip;

[0057] In order to solve the problem that the long-term influence of the sealant and the external environment will cause the sealant to age faster, resulting in deterioration, cracking, deformation, and thus failure, which will reduce the sealing performance of the outdoor box-type transformer and make it impossible to protect the internal body from rain and dust, the present application sets a repair component 2 to use a plurality of repair units 200 to repair any part of the sealing strip separately, and sets a suction cup 208 fixedly installed at the bottom of the spiral roller 204 to form adsorption with the sealing strip, so that the impeller 202 cannot rotate under the action of the wind force generated by the heat dissipation component 3. When the sealing strip ages, the adsorption of the suction cup 208 and the sealing strip is released, and the impeller 202 can rotate under the drive of the heat dissipation component 3, thereby driving the spiral roller 204 to rotate through the connecting shaft 203, and the spiral roller 204 and the two sides are arranged The cutting blade 207 is designed to be snap-fitted, so that the cutting blade 207 cuts the sealing strip.

After the glue solidifies at the bottom of the push plate 209, the repaired part is sealed, and then any part of the sealing strip can be repaired separately to prevent the sealing strip from aging and failure, and unable to protect the internal body of the transformer from rain and dust.

[0058] Specifically, a plurality of wedge blocks 216 slidably installed in an array on the outer wall of the connecting shaft 203 can be snapped with the top of the screw roller 204. When the sealing strip is aged and the adsorption of the suction cup 208 is released, the heat dissipation component 3 drives the impeller 202 to rotate, thereby driving the screw roller 204 to rotate through the connecting shaft 203 fixedly installed on the bottom of the impeller 202 and utilizing the snap-fit ​​design of the wedge block 216 and the screw roller 204. The screw roller 204 and the wedge block 212 set on the cutting blade 207 are designed with threaded snap-fit, thereby driving the cutting blade 207 to move downward to cut the sealing strip.

[0062] In order to solve the problem that the transformer generates heat during use and the transformer will be damaged if the heat is not dissipated in time, the present application sets a heat dissipation component 3 to use a servo motor 301 to drive the second impeller 302 to rotate, so that the hot air inside the bottom box 1 is transported to the heat dissipation cavity 308, and a plurality of diverter grooves 309 are set to communicate with the heat dissipation cavity 308 and the assembly cavity 218, so that the flow wind generated by the second impeller 302 flows from the plurality of diverter grooves 309 to the assembly cavity 218, so that it can act on the impellers 1 202 in the plurality of repair units 200. When the suction cup 208 and the sealing strip are released, the impeller 1 202 can generate wind direction force through the diverter groove 309 to rotate, and the hot air transported by the second impeller 302 can be collected by setting a wind collecting hood 303. The bellows 305 set at the bottom of the wind collecting hood 303 can send the hot air to the assembly roller 304, and the bellows 304 can form a spiral with the bottom of the wind collecting hood 303 through the ring 307 rotatably installed at the end. The groove is connected so that the interior of the wind collecting hood 303 is connected with the interior of the assembly roller 304. When the hot air enters the assembly roller 304, it can drive the wind wheel 1 310 to rotate. Under the mutual meshing action of the transmission shaft 311 and the wind wheel 1 310 and the wind wheel 2 312, the wind wheel 2 312 is driven to rotate in the opposite direction, and the multiple connecting holes 314 opened in the array through the inner and outer walls of the impeller 1 310 and the impeller 2 312 are allowed to flow through the hot air, thereby increasing the residence time of the hot air in the assembly roller 304, so that the hot air can be fully cooled, and then the cooled air in the assembly roller 304 is transported to the bottom box 1 through the electric telescopic tube 306, so as to play a role in heat dissipation and cooling. By setting the interior of the transmission shaft 311 to be hollow and penetrating and rotatably installed on the assembly roller 304, the external cold air can circulate in the transmission shaft 311, so that the temperature of the transmission shaft 311 is reduced, the cooling of the hot air is further improved, and the heat dissipation and cooling efficiency inside the bottom box 1 is improved.

[0063] Embodiment 3 further optimizes the outdoor box-type transformer provided in Embodiment 1 or 2. Specifically, Figure 9-12As shown, a lifting assembly 4 is provided inside the bottom box 1, and the lifting assembly 4 includes two bidirectional screw rods 401 symmetrically rotatably installed inside the bottom box 1, two receiving plates 402 symmetrically installed at the bottom of the main body 102 and correspondingly designed to the two bidirectional screw rods 401, two screw rod sleeves 405 symmetrically slidably installed on the outer wall of the bidirectional screw rod 401, the inner and outer walls of the two screw rod sleeves 405 are fixedly installed with clamping blocks 416 and are designed to be threadedly connected with the bidirectional screw rod 401, the outer walls of the two screw rod sleeves 405 are respectively hingedly installed with a connecting rod 1 403 and a connecting rod 2 404, and the connecting rod 1 403 and the connecting rod 2 404 are hingedly connected, and the ends of the connecting rod 1 403 and the connecting rod 2 404 are hingedly installed with sliders 406, and the two sliders 406 are slidably installed at the bottom of the receiving plate 402;

[0064] Both ends of the bidirectional screw rod 401 are hollow in design, and the outer wall of the bidirectional screw rod 401 is symmetrically provided with slide grooves 415 which are respectively connected with the hollow parts at both ends, and the ends of the two slide grooves 415 are butted with the spiral grooves of the bidirectional screw rod 401, and a screw 412 is rotatably installed inside any end of the bidirectional screw rod 401 and passes through the outer wall of the bottom box 1, and a screw sleeve 413 is threadedly installed on the outer wall of the screw rod 412 and is located inside the bidirectional screw rod 401, and a stop block 414 is fixedly installed on the outer wall of the screw sleeve 413 and slides in the slide groove 415, and an adjusting nut 417 is fixedly installed on the end of the screw rod 412 and is located outside the bottom box 1;

[0065] Both ends of the receiving plate 402 are fixedly installed with return springs 411, the ends of the two return springs 411 are fixedly installed with shock-absorbing plates 410, both ends of the bidirectional screw rod 401 are fixedly installed with flanges 409, the outer walls of the two flanges 409 are fixedly installed with return springs 1 408, and the ends of the two return springs 1 408 are fixedly installed with shock-absorbing rings 407 and are coaxially designed with the bidirectional screw rod 401.

[0066] In order to solve the problem that the transformer needs to be repaired, the present application sets a lifting assembly 4 and utilizes the reciprocating screw 401 to drive the two screw sleeves 405 to approach each other through the clamping design of the clamping block 416 when rotating, and the connecting rod 1 403 and the connecting rod 2 404 are respectively hinged to the two screw sleeves 405, so as to drive the slider 406 hingedly connected to the ends of the connecting rod 1 403 and the connecting rod 2 404 to slide close to the bottom of the receiving plate 402, so as to move the main plate 402 through the receiving plate 402. The main body 103 is lifted and raised, and the main body 103 is moved to the top of the bottom box 1, so that it is convenient for maintenance personnel to perform all-round maintenance on the main body 103. Compared with the open-door transformer housing, maintenance is more convenient and there is no blind spot for maintenance and no inconvenient position for maintenance. By setting the end of the slide groove 415 to dock with the spiral groove of the bidirectional screw rod 401, when the main body 103 is lowered into the bottom box 1, the screw rod sleeve 405 is moved to a certain position, and the clamping connection between the clamping block 416 and the bidirectional screw rod 401 is released, and the clamping block 416 can Slide in the slide groove 415, so that the screw sleeve 405 abuts against the shock-absorbing ring 407, and the slider 406 abuts against the shock-absorbing plate 410 set at the bottom of the receiving plate 402. Under the action of the return spring 1 408 and the return spring 2 411, it can play a shock-absorbing role, thereby reducing the noise generated by the transformer during use, playing a noise reduction role, by providing a screw 412 and a screw sleeve 413 threadedly engaged with it, and the abutment 414 fixedly installed on the outer wall of the screw sleeve 413 slides on In the slide groove, when it is necessary to move the main body 1 to the top of the bottom box 1, the screw 412 is driven to rotate by rotating the adjusting nut 417, thereby driving the stop block 414 to move in the slide groove 415 and abut against the block 416, and at the same time driving the stop block 416 to synchronously move into the spiral groove of the bidirectional screw rod 401. At the same time, the stop block 414 cannot move, thereby driving the bidirectional screw rod 401 to rotate, thereby driving the two screw rod sleeves 405 to move close, and then the main body 103 is moved to the top of the bottom box 1 for easy maintenance.

[0067] The use process of the outdoor box-type transformer provided by the present invention is as follows:

[0068] First, the servo motor 301 drives the impeller 2 302 to rotate, so that the hot air inside the bottom box 1 moves to the heat dissipation cavity 308, and the hot air is transported to the assembly cavity 218 through the diverter groove 309. At the same time, the flowing hot air can act on the impeller 1 202. When the sealing strip ages and the adsorption of the suction cup 208 is released, the impeller 1 202 rotates under the action of the hot air, thereby driving the screw roller 204 to rotate, driving the stirring rod 205 to rotate in the glue storage cavity 201, so that the insulating film 214 inside the glue storage cavity 201 is broken, and the inside of the glue storage cavity 201 is The master glue and the catalyst are mixed under the action of the stirring rod 205. At the same time, the rotation of the screw roller 204 can make the cutting blades 207 on both sides move downward to cut the aged part of the sealing strip. When the sealing strip is cut, the cutting part of the sealing strip is moved upward under the action of the push plate 209 and the compression spring 210, thereby driving the sealing plate 211 to squeeze the inside of the glue storage cavity 201. Under the action of the glue guide hole 215 and the glue injection needle 206, the glue liquid can be transported to the bottom of the push plate 209. The solidification of the glue liquid can repair the cutting part of the sealing strip.

[0069] At the same time, the hot air can be collected by the wind collecting hood 303, and the hot air inside the wind collecting hood 303 is transported to the assembly roller 304 through the bellows 305. When the hot air enters the assembly roller 304, it can drive the wind wheel 1 310 to rotate. Under the mutual meshing action of the transmission shaft 311 and the wind wheel 1 310 and the wind wheel 2 312, the wind wheel 2 312 is driven to rotate in the opposite direction, and the multiple connecting holes 314 opened in the array through the inner and outer walls of the impeller 1 310 and the impeller 2 312 are allowed to flow, thereby increasing the The hot air can stay in the assembly roller 304 for a long time so that the hot air can be fully cooled, and then the cooled air in the assembly roller 304 is transported to the bottom box 1 through the electric telescopic tube 306, so as to achieve the effect of heat dissipation and cooling. By setting the transmission shaft 311 to be hollow inside and rotatably installed on the assembly roller 304, the external cold air can circulate inside the transmission shaft 311, so that the temperature of the transmission shaft 311 is reduced, and the cooling of the hot air is further improved, and the heat dissipation and cooling efficiency inside the bottom box 1 is improved;

[0070] Under the action of the lifting assembly 4, the main body 103 can be driven to move to the top of the bottom box 1, so that it is convenient for maintenance personnel to perform all-round inspection of the main body 103. At the same time, when the main body 1 is moved to the inside of the bottom box 1, the shock-absorbing ring 407 is arranged to abut against the screw sleeve 405, and the slider 406 can abut against the shock-absorbing plate 410. Under the action of the return spring 1 408 and the return spring 2 411, the main body 103 can be shock-absorbing, thereby reducing the noise generated by the transformer during use.
