DETAILED DESCRIPTION

[0025] Embodiment 1, as shown in the transformer body 1, a wind power energy storage transformer with high heat dissipation function includes a transformer body 1, and a plurality of heat dissipation fin bodies 2 are evenly installed around the transformer body 1. Cleaning scrapers 3 are arranged around the transformer body 1 for cleaning fallen leaves in the gaps between adjacent heat dissipation fin bodies 2, and the cleaning scrapers 3 are arranged at the top of the heat dissipation fin bodies 2; driving components 4 are installed on both sides of the cleaning scraper 3, and a locking component 5 is arranged between the cleaning scraper 3 and the driving component 4.

[0026] In this embodiment, the transformer body 1 for wind power energy storage is installed in advance. Usually, in order to improve the heat dissipation effect of the transformer body 1, a heat dissipation fin body 2 is often installed around the transformer body 1 for heat dissipation. The transformer body 1 installed in the mountainous area is cleaned. Usually, the transformer body 1 installed in the mountainous area is usually disturbed by fallen leaves. If the fallen leaves are not cleaned in time, the heat dissipation of the heat dissipation fin body 2 will be affected. Therefore, the fallen leaves in the gap can be cleaned regularly. The cleaning scraper 3 is driven by the driving component 4 to rotate 90 degrees counterclockwise and then lifted to clean the fallen leaves. The locking component 5 is used to lock the cleaning scraper 3 when the cleaning scraper 3 rotates 90 degrees counterclockwise.

[0027] As shown in the figure of the heat sink body 2, further, the cleaning scraper 3 is composed of a plurality of U-shaped scrapers, a straight scraper, and a cross bar. The U-shaped scraper and the straight scraper are fixedly connected to the top of the cross bar. The gap between two adjacent U-shaped scrapers is equal to the gap between two adjacent heat sink fin bodies 2. The number of straight scrapers arranged on each cross bar is set to two, and they are respectively arranged on both sides of the top of the cross bar. The gap between the straight scraper and the adjacent U-shaped scraper is equal to the thickness of the heat sink body 2. The U-shaped scraper and the straight scraper are set in a vertical state in the initial state, which can prevent fallen leaves from falling into the surface of the U-shaped scraper and the straight scraper, affecting the heat dissipation of the heat sink body 2.

[0028] As shown in the transformer body 1 to the driving component 4, as the specific structure in this embodiment, the driving component 4 includes a gear 401, one side of the gear 401 is meshedly connected with a rack 403, the rack 403 is fixedly connected to the transformer body 1, and a rotating rod 402 is fixedly connected inside the gear 401. The rotating rod 402 is connected to the cleaning scraper 3 through a locking component 5. A protrusion 405 is provided on the outer side of the locking component 5, and the protrusion 405 is connected to the transformer body 1 through an electric push rod 404.

[0029] The locking assembly 5 includes a rotating shaft 501, which is fixedly connected to the inside of the cross bar. A sleeve 502 is provided on the outside of the rotating shaft 501 and the rotating rod 402, and the sleeve 502 passes through the protrusion 405 and is threadedly connected thereto; a first sliding groove 504 is provided inside the sleeve 502, and two groups of first sliding blocks 503 are slidably connected inside the first sliding groove 504, and the two groups of first sliding blocks 503 are respectively fixedly connected to the outside of the rotating shaft 501 and the rotating rod 402; a support plate is fixedly connected to the top of the protrusion 405, and the rotating rod 402 and the rotating shaft 501 respectively pass through the support plate and are rotatably connected thereto.

[0030] In this embodiment, when cleaning fallen leaves between adjacent heat dissipation fin bodies 2, the electric push rod 404 can be started to drive the protrusion 405 to move downward, and the protrusion 405 moves downward to drive the sleeve 502 to move downward, and the sleeve 502 moves downward to drive the rotating rod 402 and the rotating shaft 501 to move downward. Since the cleaning scraper 3 is fixedly connected to the outer side of the rotating shaft 501, the rotating shaft 501 moves downward to drive the cleaning scraper 3 to move downward, and at the same time, the rotating rod 402 moves downward to drive the gear 401 to move downward. When the gear 401 moves downward The gear 401 rotates 90 degrees counterclockwise due to the meshing force of the rack 403, and the gear 401 rotates 90 degrees counterclockwise to drive the rotating rod 402 to rotate. Since the first slider 503 slides in the first slide groove 504, the rotating rod 402 rotates to drive the sleeve 502 to rotate. Since the sleeve 502 and the protrusion 405 are threadedly connected, the rotating rod 402 rotates to drive the sleeve 502 to slide in the direction of the cleaning scraper 3. The angle of the rotating rod 402 and the rotating shaft 501 is locked through the cooperation between the sleeve 502 and the protrusion 405.

[0031] When the sleeve 502 rotates 90 degrees counterclockwise, it can drive the rotating shaft 501 to rotate 90 degrees counterclockwise. After the rotating shaft 501 rotates 90 degrees counterclockwise and drives the cleaning scraper 3 to rotate 90 degrees counterclockwise, the gear 401 and the rack 403 are disengaged. At this time, the protrusion 405 moves back and forth up and down under the drive of the electric push rod 404, thereby cleaning the fallen leaves between the gaps of adjacent heat dissipating fin bodies 2.

[0032] In the second embodiment, as shown in the transformer body 1 and the locking assembly 5, multiple heat dissipation fin bodies 2 are provided with multiple rows of heat dissipation holes 6, the aperture of each row of heat dissipation holes 6 gradually decreases from both ends inward, and the two sides of the central axis of the multiple heat dissipation holes 6 are mirror-imaged.

[0033] In the present embodiment, each heat sink body 2 is provided with a plurality of heat sink holes 6 distributed longitudinally, and the aperture sizes of the plurality of heat sink holes 6 distributed longitudinally on each heat sink body 2 are the same. The heat sink holes 6 are arranged so that when the wind blows perpendicularly to the heat sink body 2, the wind can pass through the heat sink holes 6, and the aperture sizes of the heat sink holes 6 distributed transversely gradually decrease from both ends inwardly. The decrease in aperture size from both ends inwardly can increase the pressure of the wind passing through, improve the ventilation effect, and improve the heat dissipation effect.

[0034] Furthermore, a brush 7 is provided at intervals within each of the plurality of U-shaped scrapers for cleaning dust inside the heat dissipation holes 6 , and through holes are provided on both sides of each U-shaped scraper, through which the brush 7 can pass.

[0035] In this embodiment, the brush 7 is made of a soft brush 7. When the brush 7 moves downward with the U-shaped scraper, it can penetrate into the heat dissipation hole 6 along the through hole to clean the dust and fallen leaves inside the heat dissipation hole 6, thereby improving the ventilation and heat dissipation effect. A brush 7 is arranged at each interval in the U-shaped scraper. The U-shaped scraper with no interval is not equipped with a brush 7. The U-shaped scraper with this interval can be used for garbage discharge channel.

[0036] As shown in the locking assembly 5 to the heat dissipation hole 6, as a specific structure in this embodiment, a transmission assembly 8 is provided on the side away from each other of two symmetrically arranged brushes 7, and the transmission assembly 8 includes a support rod 806, a support rod 806 is fixedly connected to the inner wall of the U-shaped scraper, and a round rod 804 is fixedly connected inside the support rod 806, and a connecting rod 801 is slidably connected to the outer side of the round rod 804, and the connecting rod 801 is fixedly connected to the brush 7, and the connecting rod 801 is connected to the support rod 806 through a spring 803; the cross-sectional shape of the outer end of the connecting rod 801 close to the brush 7 is set to be a trapezoid.

[0037] The connecting rod 801 is rotatably connected to the side away from the brush 7 with a disk 802, which is slidably connected to the outside of the round rod 804, and the disk 802 is connected to the support rod 806 via a spring 803; a second slide groove 805 is provided inside the connecting rod 801, and a second slider is slidably connected inside the second slide groove 805, and the second slider is fixedly connected to the outside of the round rod 804.

[0038] In this embodiment, the cleaning scraper 3 moves downward and drives the brush 7 to move downward. When the brush 7 moves to the position of the heat dissipation hole 6, the connecting rod 801 is moved toward the heat dissipation hole 6 by the elastic force of the spring 803. The movement of the connecting rod 801 drives the brush 7 to move, so that the brush 7 bounces into the heat dissipation hole 6 to clean the garbage and fallen leaves inside the heat dissipation hole 6. The cleaned garbage and fallen leaves fall into the U-shaped scraper arranged at intervals. The U-shaped scraper without the brush 7 here serves as a circulation channel for garbage and fallen leaves. When the U-shaped scraper moves up and down with the electric push rod 404, the cross-sectional shape of the connecting rod 801 is set to a trapezoid. The connecting rod 801 is squeezed by the side wall of the heat dissipation hole 6 and retracts toward the direction close to the support rod 806. According to the same principle, the inside of the heat dissipation hole 6 is repeatedly cleaned;

[0039] Furthermore, since a second slide groove 805 is provided inside the connecting rod 801, when the disk 802 is driven by the force of the spring 803 to move together with the connecting rod 801 toward the direction of the heat dissipation hole 6, the second slider is located in the second slide groove 805 and slides, thereby driving the connecting rod 801 to rotate and move toward the direction of the heat dissipation hole 6, so as to clean the inside of the heat dissipation hole 6.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
