DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 are within the scope of protection of the present invention.

[0033] Example 1

[0034] See also Figures 1 to 8 , a structural diagram of a transformer heat dissipation structure provided in Example 1 of the present invention, the transformer heat dissipation structure comprises: a base 100, a transformer body 200, a heat dissipation fin component 300 and an air cooling component 400, the transformer body 200 is mounted on the base 100, a heat dissipation fin component 300 is arranged in an array on the outer side of the transformer body 200, the heat dissipation fin component 300 comprises a plurality of heat dissipation fin units 303, and the heat dissipation fin units 303 are arranged in a rectangular array on the outer side of the transformer body 200; the heat dissipation fin unit 303 comprises a mounting shaft 301 which is rotated to be mounted on the transformer body 200, and the outer circumference of the mounting shaft 301 Two arc-shaped mounting shafts 301 are arranged in an array. The heat sink fin unit 303 has a first position and a second position. The heat sink fin unit 303 is in an inclined state when in the first position, and in a vertical state when in the second position. In order to clean the dust on the surface of the heat sink fin component 300, a rotating component that drives a plurality of heat sink fin units 303 to rotate suddenly at the same time is installed on the transformer body 200; the heat sink fin component 300 is fixedly installed on the base 100 and is arranged below the transformer body 200, and is used to transport cooling air to the heat sink fin component 300 outside the transformer body 200;

[0035] The rotating assembly and the heat dissipation fin component 300 are both connected to the control component 500 . The control component 500 is used to control the rotation of the rotating assembly and the power supply of the heat dissipation fin component 300 based on the temperature of the transformer body 200 .

[0036] In the present invention, when the transformer body 200 is working at a low load, the heat dissipated by the heat dissipation is relatively low. At this time, the temperature of the outer side of the transformer body 200 is relatively low, and the heat dissipation fin unit 303 is in the first position, that is, the inclined state, and the heat dissipation fin unit 303 dissipates heat. When the transformer body 200 is working at a high load, its surface temperature will increase. At this time, the control component 500 drives the rotating assembly to drive a number of heat dissipation fin units 303 to rotate suddenly. During the sudden rotation, the dust on the surface of the heat dissipation fin unit 303 can be shaken off, reducing the dust accumulation on the surface of the heat dissipation fin unit 303. At the same time, the number of heat dissipation fin units 303 are in a vertical state, and the control component 500 drives the air cooling component 400 to transport air to the outside of the transformer body 200. Since the number of groups of heat dissipation fin units 303 are in a vertical state, a number of vertical flows are formed, which can enable the air to be well transported from bottom to top, so that the air can quickly take away the heat on the surface of the transformer body 200. In the initial state of the present invention, heat is dissipated by the heat dissipation fin component 300, and in the high-temperature state, heat is dissipated by the heat dissipation fin component 300 and the air-cooling component 400. Different heat dissipation modes can be selected according to needs to reduce energy effects. At the same time, when the state of the mounting shaft 301 is switched, the sudden rotation can shake off the dust on the surface of the mounting shaft 301, thereby cleaning the dust on the surface of the mounting shaft 301 and improving the cleaning effect.

[0037] Heat dissipation fin components 300 may be disposed around the outer sides of the transformer body 200 .

[0038] like Figure 2 and Figure 5 As shown, in some embodiments, the vertical distance between adjacent mounting shafts 301 in the vertical direction is less than the vertical length of two heat sink fins 302. In this way, there is an overlapping area between the heat sink fins 302 between adjacent mounting shafts 301. Since the heat sink fins 302 have a certain elasticity, the two will collide with each other during the rotation process, and the dust on their surfaces can be shaken off, thereby improving the dust removal effect. When the heat sink fin unit 303 is in the first position, an inclined strip flow channel is formed to facilitate the flow of hot air. At this time, the heat sink fins 302 on the adjacent mounting shafts 301 will not overlap, so that the heat sink fins 302 can fully dissipate heat.

[0039] Specifically, the heat dissipation fin 302 on the right side of the mounting shaft 301 is bent upward at one end away from the mounting shaft 301, while the heat dissipation fin 302 on the left side of the mounting shaft 301 is bent downward at one end away from the mounting shaft 301, so that when colliding between adjacent heat dissipation fins 302, the end of the heat dissipation fin 302 collides with the middle position of the adjacent heat dissipation fin 302.

[0040] like Figure 3 As shown, in some embodiments, the rotating assembly includes a gear 304 fixedly sleeved on the mounting shaft 301, the gear 304 meshes with an adjacent rack 306, the rack 306 is fixedly mounted on the mounting rod 305, the mounting rod 305 is vertically slidably mounted on the transformer body 200, and the rotating assembly also includes a control assembly that drives the mounting rod 305 to move up and down. When the heat sink fin unit 303 needs to be converted from the first position to the second position, the control assembly drives the mounting rod 305 to move the rack 306 upward to drive the gear 304 to drive the mounting shaft 301 to rotate counterclockwise, so that the heat sink fin unit 303 is converted from an inclined state to a vertical state.

[0041] like Figure 6 As shown, in some embodiments, the control component includes a cross bar 307 and a locking structure, the cross bar 307 is horizontally arranged, and the lower ends of several mounting rods 305 are fixedly installed on the cross bar 307, and a connecting L rod 308 is fixedly installed on the cross bar 307, and the connecting L rod 308 passes through a mounting sleeve 313 fixedly installed on the transformer body 200, and a first elastic member 309 is sleeved on the outer side of the connecting L rod 308, and the two ends of the first elastic member 309 are respectively fixedly installed on the connecting L rod 308 and the mounting sleeve 313, and the locking structure is arranged between the transformer body 200 and the connecting L rod 308, and is used to lock the position of the connecting L rod 308. Initially, the connecting L rod 308 is located at a low position, and the locking structure locks the connecting L rod 308. When the temperature needs to be increased, the locking structure releases the lock on the position of the connecting L rod 308, and the connecting L rod 308 suddenly moves upward under the action of elasticity, thereby driving the mounting rod 305 to move upward, and switching the position of the heat sink fin unit 303.

[0042] In some embodiments, the first elastic member 309 is a coil spring.

[0043] In some embodiments, the locking mechanism includes a magnetic member 311 fixedly mounted on the transformer body 200 and a mounting ring 310 fixedly mounted on the connecting L-rod 308, wherein the 308 is arranged through the magnetic member 311, and an electromagnet 312 is arranged on the mounting ring 310, wherein the electromagnet 312 is a ferromagnetic member, and the magnetic member 311 is an electromagnet. Specifically, when the temperature rises, the magnetic member 311 is powered off, the magnetic member 311 loses its magnetism, and the connecting L-rod 308 moves upward rapidly under the action of elasticity. When the connecting L-rod 308 needs to be restored to its initial position, the magnetic member 311 is powered on, and the electromagnet 312 approaches the magnetic member 311 under the action of suction, so that the connecting L-rod 308 moves downward.

[0044] In some embodiments, the air-cooling component 400 includes a bellows 401 fixedly mounted on the base 100, a plurality of openings being arranged on the outside of the bellows 401, an annular filter 405 being rotatably arranged inside the bellows 401, the annular filter 405 being used to filter the air entering the bellows 401 through the opening, a fan 409 being installed inside the bellows 401, an air distributor 402 being installed on the top of the bellows 401, the top output end of the bellows 401 being connected to the input end of the air distributor 402, and the air distributor 402 being used to disperse the airflow to the outside of the transformer body 200.

[0045] like Figure 1 and Figure 7 As shown, in some embodiments, the wind box 401 is further provided with a regeneration chamber 403, the annular filter screen 405 passes through the regeneration chamber 403, a dust discharge port is provided at the bottom of the regeneration chamber 403, and a dust accumulation groove 404 is installed on the dust discharge port. The dust accumulation groove 404 is used to collect dust, and a recovery component is provided inside the regeneration chamber 403.

[0046] like Figure 4 As shown, in some embodiments, the bellows 401 is provided with a driving mechanism for driving the annular filter 405 to rotate.

[0047] like Figure 4 As shown, in some embodiments, the driving mechanism includes a driving motor 408 fixedly installed inside the bellows 401, and a first gear 407 is installed at the output end of the driving motor 408. The first gear 407 is meshed with a first gear ring 406 on the annular filter screen 405. The first gear ring 406 is installed above the annular filter screen 405 and is concentric with the annular filter screen 405, thereby providing power for the rotation of the annular filter screen 405.

[0048] like Figure 6As shown, in some embodiments, the recovery component includes cleaning wheels 410 arranged on both sides of the annular filter 405, the cleaning wheels 410 are rotatably installed inside the regeneration chamber 403, and the cleaning wheels 410 are attached to the surface of the annular filter 405, and the cleaning wheels 410 are set in the opposite direction of rotation to the annular filter 405.

[0049] like Figure 8 As shown, in some embodiments, in order to drive the cleaning wheel 410 to rotate, a transmission mechanism is provided between the first gear ring 406 and the cleaning wheel 410 .

[0050] like Figure 8 As shown, in some embodiments, the transmission mechanism includes a second gear 411 and a third gear 412, wherein the third gear 412 is connected to the dust cleaning wheel 410 and is concentric with the dust cleaning wheel 410; the third gear 412 is meshed with the second gear 411, and the second gear 411 is rotatably mounted on the inner wall of the bellows 401, and the second gear 411 is also meshed with the first gear ring 406. The first gear ring 406 drives the second gear 411 to rotate, and then the second gear 411 drives the third gear 412 to rotate, and the second gear 411 and the third gear 412 rotate in opposite directions, but the second gear 411 and the first gear ring 406 rotate in the same direction, so that the third gear 412 rotates in opposite directions to the first gear ring 406, so that the dust on the surface of the first gear ring 406 can be cleaned well. Teeth are arranged on both sides of the first gear ring 406.

[0051] like Figure 8 As shown, in some embodiments, the radius of the second gear 411 is greater than the radius of the third gear 412, and the second gear 411 can accelerate the third gear 412 and the cleaning wheel 410 to improve the cleaning effect, thereby improving the mixing effect.

[0052] In some embodiments, the control component 500 includes a temperature sensor and a controller installed on the transformer body 200. The temperature sensor is used to obtain the temperature of the transformer body 200 and transmit the temperature signal to the controller. If the temperature reaches a set high threshold, the heat sink fin component 300 is controlled to work and the magnetic component 311 is powered off; if the temperature is lower than the set low threshold, the heat sink fin component 300 is controlled to stop working and the magnetic component 311 is powered on. The controller is also electrically connected to the drive motor 408 to control the power on and off of the drive motor 408.

[0053] The working principle of the present invention is:

[0054] When the transformer body 200 is working at a low load, the heat dissipated by the heat dissipation is relatively low. At this time, the temperature outside the transformer body 200 is relatively low, and the heat dissipation fin unit 303 is in the first position, that is, the tilted state, and the heat dissipation fin unit 303 dissipates heat. When the transformer body 200 is working at a high load, its surface temperature will increase. At this time, the control component 500 controls the magnetic component 311 to cut off the power, and the connecting L rod 308 moves upward under the action of the first elastic member 309, and then drives the multiple mounting shafts 301 to rotate suddenly through the mounting rod 305. During the sudden rotation, the heat dissipation fin 302 collides with the adjacent heat dissipation fin 302, and the dust on its surface is shaken off, reducing the dust on the surface of the heat dissipation fin unit 303. At the same time, several heat dissipation fin units 303 are in a vertical state. At the same time, the control component 500 drives the air cooling component 400 to transport air to the outside of the transformer body 200. Since several groups of heat dissipation fin units 303 are in a vertical state, several vertical flows are formed, which can enable the air to be well transported from bottom to top, so that the air can quickly take away the heat on the surface of the transformer body 200. When a lot of dust accumulates on the annular filter 405, the control component 500 controls the driving motor 408 to rotate, thereby causing the annular filter 405 to rotate, and then drives the annular filter 405 to rotate through the first gear ring 406, the first gear 407 and the third gear 412. At the same time, the cleaning wheel 410 rotates to clean the surface of the annular filter 405 inside the regeneration chamber 403 to increase air flow and avoid the problem of manual cleaning in the prior art.
