Description

Technical Field

[0001] The present invention belongs to the technical field of transformers, and in particular to an embedded tower transformer for offshore wind power generation. Background Art

[0002] An embedded offshore wind turbine tower transformer is a type of electrical equipment designed specifically for offshore wind turbines. Installed inside the offshore wind turbine tower, it utilizes electromagnetic induction to transform AC voltage. Its main components include a primary coil, a secondary coil, and an iron (magnetic) core. These transformers perform key functions including voltage conversion, current conversion, impedance conversion, electrical isolation, and voltage regulation.

[0003] Patent announcement number CN207993621U discloses a special external-mounted transformer for wind turbine tower substations. Its structure includes an oil level gauge, a low-voltage bushing, a high-voltage bushing, a top cover, a transformer body, an oil drain valve, an external mounting bracket, an oil tank, and a radiator. The side edge of the transformer body is threadedly connected to the side edge of the oil drain valve, and the bottom surface of the oil tank is located on the inner bottom edge of the transformer body. The patent provides an external mounting bracket. By pulling the support frame, the crossbar and clamping plate are brought closer to the transformer body and fixed together with bolts. The external mounting bracket body is pulled out of the support frame via the guide rails to adjust the height according to the transformer body. After adjustment, the lock is pressed to lock the external mounting bracket body and the support frame. This makes the mounting bracket less likely to shake when placed in a wind turbine tower substation, improving the external mounting effect of the transformer in the wind turbine tower substation.

[0016] The beneficial effects of the present invention are as follows: 1. The embedded offshore wind power tower transformer described in the present invention is configured to fit the support rod three and the curved plate to the outer wall of the wind power tower, and then pass the bolts through the mounting holes on the support rod three and the curved plate and screw them into the outer wall of the wind power tower to fix them. The support rod three and the curved plate can then be fixed to the outer wall of the wind power tower. The high-voltage terminal is used to connect the high-voltage side circuit of the transformer body, and the low-voltage terminal is used to connect the low-voltage side circuit of the transformer body, thereby completing the installation of the transformer body. This allows the transformer body to be fixed a second time under the commonly used embedded fixing method, making the connection between the transformer body and the wind power tower more secure and preventing the transformer body from loosening at the wind power tower.

[0017] 2. The embedded offshore wind power tower transformer described in the present invention utilizes an anti-scraping impurity removal component. Whenever the transformer body has been working for a period of time, the scraper is driven to rise along the surface of the heat sink to scrape off the impurities attached to the surface of the heat sink, thereby avoiding the situation where impurities adhere to the surface of the heat sink and form a barrier on the surface of the heat sink, which hinders the dissipation of heat and affects the heat dissipation effect of the transformer body. The scraping bar moves synchronously with the receiving plate, and the two always maintain a fixed distance. The scraped impurities will be received by the receiving plate, thereby preventing the impurities scraped by the scraping bar from falling and scratching the surface of the heat sink, which is beneficial to extending the service life of the heat sink, and also preventing dust from accumulating in the scratches of the heat sink and being difficult to be scraped off by the scraping bar, thereby affecting the heat dissipation performance of the heat sink. Moreover, every time the receiving plate moves a certain distance, the push plate pushes the impurities away from the edge of the receiving plate, thereby preventing the impurities from sliding along the scraping bar. As the impurities accumulate at the edge of the receiving plate, the impurities are higher than the upper edge of the scraping bar, and the sharp end of the impurity fits the surface of the heat sink. When the receiving plate continues to drive the impurities to rise, the sharp end of the impurity scratches the surface of the heat sink, causing the surface of the heat sink to be scratched. Moreover, the multiple movements of the push plate are not driven by electricity, which is beneficial to saving electricity. In addition, when the push plate moves toward the middle of the receiving plate, the scraper is always in contact with the surface of the heat sink under the action of spring 1. There will be no situation where the push plate and the scraper move away from the inner wall of the heat sink at the same time, resulting in a gap between the push plate and the scraper and the heat sink, and impurities enter the gap, affecting the normal operation of the subsequent push plate and the scraper.

[0018] 3. In the embedded offshore wind power tower transformer described in the present invention, when the receiving plate is flipped to remove impurities on its surface, the receiving plate can vibrate, thereby accelerating the separation of impurities from the receiving plate and avoiding the situation where impurities remain on the surface of the receiving plate and affect its subsequent use.

[0019] 4. The embedded offshore wind power tower transformer described in the present invention can convert solar energy into electrical energy through solar panels and provide electrical energy for the anti-scratch impurity removal component to ensure its stable and continuous operation.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please refer to Figures 1-8 The present invention provides a technical solution: an embedded offshore wind power tower transformer, comprising a base 12, a transformer body 1 disposed on the upper end surface of the base 12, a plurality of high-voltage terminals 2 and a low-voltage terminal 3 disposed on the upper end of the transformer body 1, a plurality of heat sinks 5 disposed on one side of the transformer body 1, and an anti-scratch impurity removal component for removing impurities from the surface of the heat sink 5 disposed on the transformer body 1; The anti-scratch impurity removal component includes a threaded block 14 and a slider 16 that are slidably connected to both sides of the transformer body 1.

[0025] In this embodiment, Figure 1 As shown, both sides of the lower end surface of the base 12 are fixedly connected to support rod 1 8, one side of support rod 1 8 is fixedly connected to support rod 2 9, and one end of support rod 2 9 is fixedly connected to support rod 3 10.

[0026] The arc-shaped plate 11 is fixedly connected to one side of the base 12 , and mounting holes are provided on both sides of the arc-shaped plate 11 .

[0027] Specifically, the support rod 3 10 and the curved plate 11 are fitted to the outer wall of the wind turbine tower, and then bolts are passed through the mounting holes on the support rod 3 10 and the curved plate 11 and screwed into the outer wall of the wind turbine tower to fix the support rod 3 10 and the curved plate 11 to the outer wall of the wind turbine tower. The high-voltage terminal 2 is used to connect the high-voltage side circuit of the transformer body 1, and the low-voltage terminal 3 is used to connect the low-voltage side circuit of the transformer body 1. This completes the installation of the transformer body 1. This allows the transformer body 1 to be fixed twice in the commonly used embedded fixing method, making the connection between the transformer body 1 and the wind turbine tower more secure and preventing the transformer body 1 from loosening on the wind turbine tower.

[0028] In this embodiment, Figure 2-Figure 5 、 Figure 7 、 Figure 8 As shown, one side of the threaded block 14 is threadedly connected to a threaded rod 13, both ends of the threaded rod 13 are rotatably set on the transformer body 1, one side of the transformer body 1 is fixedly connected to a motor 2 18, and the output end of the motor 2 18 is fixedly connected to one end of the threaded rod 13.

[0029] One end of the telescopic rod 15 is fixedly connected to the motor 17, and the output end of the motor 17 is fixedly connected to one end of the connecting plate 6.

[0030] A plurality of protrusions 30 are intermittently provided along the longitudinal direction on one side of the heat sink 5, a fixed column 29 is fixedly connected to one side of the receiving plate 7, and the fixed column 29 is slidably connected to the reciprocating block 26. Connecting rod three 25 is rotatably provided on both sides of the reciprocating block 26, and one end of the connecting rod three 25 is rotatably connected to one end of the push plate 22.

[0031] A spring 28 is sleeved on one side of the fixed column 29. One end of the spring 28 is fixedly connected to the receiving plate 7, and the other end is fixedly connected to the end of the fixed column 29. A transmission rod 31 is fixedly connected to one side of the reciprocating block 26. When the transmission rod 31 moves longitudinally, it can intermittently contact multiple protrusions 30.

[0032] A spring 27 is fixedly connected to one side of the lower end of the scraper strip 23 , and an end of the spring 27 away from the scraper strip 23 is fixedly connected to one side of the push plate 22 .

[0033] Specifically, when the existing transformer is in use, the heat sink 5 is used to dissipate heat from the transformer body 1. However, since the heat sink 5 is exposed to the outside, dust, particles and other impurities will adhere to the surface of the heat sink 5 after a long period of operation. After these impurities adhere to the surface of the heat sink 5, they will form a layer of barrier on the surface of the heat sink 5, thereby hindering the dissipation of heat and affecting the heat dissipation effect of the transformer body 1. Therefore, in order to solve the above-mentioned problem, in the present embodiment, the receiving plate 7 is initially located at the lower edge of the heat sink 5 when in use. Whenever the transformer body 1 has been operating for a period of time, the motor 2 18 drives the threaded rod 13 to rotate, causing the threaded block 14 and the slider 16 to slide upward. Since the scraper 23 is in contact with the surface of the heat sink 5, the scraper 23 scrapes off impurities adhering to the surface of the heat sink 5 as it rises, and the scraped impurities fall onto the surface of the receiving plate 7 until the scraper 23 moves to the upper edge of the heat sink 5. The scraper 23 is then driven downward to reset, thereby completing the removal of impurities from the surface of the heat sink 5. This prevents impurities from adhering to the surface of the heat sink 5 and forming a barrier on the surface of the heat sink 5, thereby hindering heat dissipation and affecting the heat dissipation effect of the transformer body 1. In addition, since some impurities are of high hardness, such as stones, soil blocks, etc., such impurities may be mixed with mud and adhere to the surface of the heat sink 5. When the scraper 23 scrapes them off, they will fall downward. During the falling process, the kinetic potential energy of the impurities continues to increase. If the impurities are relatively sharp and contact the surface of the heat sink 5 during the falling process, it may cause scratches on the surface of the heat sink 5. Not only will it easily cause the heat sink 5 to deform or break during subsequent use, affecting the use of the heat sink 5, but dust may also accumulate at the scratches and cannot be scraped off smoothly by the scraper 23, affecting the heat dissipation performance of the heat sink 5. Therefore, in order to avoid this situation, the receiving plate 7 and the scraper 23 move synchronously, and the two always maintain a fixed distance. The scraped impurities will be received by the receiving plate 7, thereby avoiding the situation where the impurities scraped off by the scraper 23 scratch the surface of the heat sink 5, which is beneficial to extending the service life of the heat sink 5, and also avoiding the situation where dust accumulates at the scratches of the heat sink 5, which is difficult to be scraped off by the scraper 23, affecting the heat dissipation performance of the heat sink 5.

[0034] When the scraping strip 23 completes one scraping operation and the receiving plate 7 drops to a height where its end does not touch the surface of the transformer body 1, the motor 17 drives the connecting plate 6 to rotate, causing the receiving plate 7 to flip over, so that impurities on the surface of the receiving plate 7 fall off, thereby avoiding the situation where excessive impurities accumulate on the surface of the receiving plate 7 and affect the subsequent receiving effect; Although the above method can prevent the scraped impurities from scratching the heat sink 5, the impurities will easily accumulate at the edge of the receiving plate 7 after sliding along the scraper bar 23. If the impurities are too large or the accumulated quantity is too large, the impurities will easily be higher than the upper edge of the scraper bar 23. The sharp end of the impurity may contact the surface of the heat sink 5. At this time, the receiving plate 7 continues to drive the impurities upward, and the sharp end of the impurity will still scratch the surface of the heat sink 5, causing the surface of the heat sink 5 to be scratched. Therefore, in order to avoid this situation, when the receiving plate 7 moves upward, the transmission rod 31 will intermittently contact with multiple protrusions 30. When the transmission rod 31 contacts the protrusions 30, the transmission rod 31 will move away from the receiving plate 7. At this time, the connecting rod 35 drives the push plate 22 to slide on the limit rod 24, and the two push plates 22 on the same receiving plate 7 approach each other, pushing the impurities at the edge of the receiving plate 7 to the middle of the receiving plate 7, so that the impurities are away from the surface of the heat sink 5. After the transmission rod 31 passes the protrusion 30, it will Under the action of spring 28, the receiving plate 7 is reset. Each time the receiving plate 7 moves a certain distance, the push plate 22 pushes the impurities, thereby preventing the impurities from sliding along the scraper 23. As the impurities accumulate at the edge of the receiving plate 7, the impurities are higher than the upper edge of the scraper 23, and the sharp ends of the impurities contact the surface of the heat sink 5. As the receiving plate 7 continues to drive the impurities upward, the sharp ends of the impurities scrape against the surface of the heat sink 5, causing scratches on the surface of the heat sink 5. In addition, the multiple movements of the push plate 22 are not driven by electricity, which helps save electricity. In addition, when the push plate 22 moves toward the middle of the receiving plate 7, the scraper 23 is always in contact with the surface of the heat sink 5 under the action of spring 1 27. This prevents the push plate 22 and scraper 23 from simultaneously moving away from the inner wall of the heat sink 5, resulting in a gap between the push plate 22 and scraper 23 and the heat sink 5, which would allow impurities to enter the gap and affect the subsequent normal operation of the push plate 22 and scraper 23.

[0035] In this embodiment, Figure 6 As shown, a connecting rod 20 is rotatably provided on one side of the threaded block 14, a connecting rod 21 is rotatably provided on one end of the connecting rod 20, one end of the connecting rod 21 is rotatably connected to one end of the telescopic rod 15, and a motor 3 19 is fixedly connected to one side of the threaded block 14, and the output end of the motor 3 19 is fixedly connected to one end of the connecting rod 20.

[0036] Specifically, when the receiving plate 7 is turned over to drop impurities on its surface, the impurities may be difficult to drop due to their strong adhesion. Therefore, in order to avoid this situation, the motor 3 19 drives the connecting rod 1 20 to rotate, and the telescopic rod 15 is moved back and forth under the action of the connecting rod 2 21, so that the receiving plate 7 vibrates, which can accelerate the separation of impurities from the receiving plate 7 by vibration, thereby avoiding the situation where impurities remain on the surface of the receiving plate 7 and affect its subsequent use.

[0037] In this embodiment, Figure 1 As shown, a solar panel 4 is provided on one side of the upper end surface of the transformer body 1 .

[0038] Specifically, solar energy can be converted into electrical energy through the solar panel 4, and provide electrical energy for the anti-scratch impurity removal component to ensure its stable and continuous operation.

[0039] Working principle: fit the support rod 3 10 and the curved plate 11 to the outer wall of the wind turbine tower, then pass the bolts through the mounting holes on the support rod 3 10 and the curved plate 11 and screw them into the outer wall of the wind turbine tower to fix the support rod 3 10 and the curved plate 11 to the outer wall of the wind turbine tower. The high-voltage terminal 2 is used to connect the high-voltage side circuit of the transformer body 1, and the low-voltage terminal 3 is used to connect the low-voltage side circuit of the transformer body 1, thus completing the installation of the transformer body 1. This allows the transformer body 1 to be fixed a second time in the commonly used embedded fixing method, making the connection between the transformer body 1 and the wind turbine tower more secure, and the transformer body 1 is less likely to become loose at the wind turbine tower. In the initial state, the receiving plate 7 is located at the lower edge of the heat sink 5. Whenever the transformer main body 1 has been working for a period of time, the motor 2 18 drives the threaded rod 13 to rotate, causing the threaded block 14 and the slider 16 to slide upward. Since the scraper 23 is in contact with the surface of the heat sink 5, the scraper 23 will scrape off the impurities attached to the surface of the heat sink 5 when it rises, and the scraped impurities will fall on the surface of the receiving plate 7 until the scraper 23 moves to the upper edge of the heat sink 5, and then the scraper 23 is driven to reset downward, thereby achieving the cleaning of impurities on the surface of the heat sink 5, thereby avoiding the situation where impurities adhere to the surface of the heat sink 5 and form a barrier on the surface of the heat sink 5, resulting in the obstruction of heat dissipation and affecting the heat dissipation effect of the transformer main body 1. In addition, since some impurities are of high hardness, such as stones, soil blocks, etc., such impurities may be mixed with mud and adhere to the surface of the heat sink 5. When the scraper 23 scrapes them off, they will fall downward. During the falling process, the kinetic potential energy of the impurities continues to increase. If the impurities are relatively sharp and contact the surface of the heat sink 5 during the falling process, it may cause scratches on the surface of the heat sink 5. Not only will it easily cause the heat sink 5 to deform or break during subsequent use, affecting the use of the heat sink 5, but dust may also accumulate at the scratches and cannot be scraped off smoothly by the scraper 23, affecting the heat dissipation performance of the heat sink 5. Therefore, in order to avoid this situation, the receiving plate 7 and the scraper 23 move synchronously, and the two always maintain a fixed distance. The scraped impurities will be received by the receiving plate 7, thereby avoiding the situation where the impurities scraped off by the scraper 23 scratch the surface of the heat sink 5, which is beneficial to extending the service life of the heat sink 5, and also avoiding the situation where dust accumulates at the scratches of the heat sink 5, which is difficult to be scraped off by the scraper 23, affecting the heat dissipation performance of the heat sink 5.When the scraping bar 23 completes a scraping work and the receiving plate 7 drops to a height where its end does not touch the surface of the transformer body 1, the motor 17 drives the connecting plate 6 to rotate, causing the receiving plate 7 to flip over, so that impurities on the surface of the receiving plate 7 fall off, thereby avoiding the situation where excessive impurities accumulate on the surface of the receiving plate 7 and affect the subsequent receiving effect; although the above method can prevent the scraped impurities from scratching the heat sink 5, the impurities are likely to accumulate at the edge of the receiving plate 7 after sliding along the scraping bar 23. If the volume of the impurities is too large or the amount of accumulation is too large, the impurities are likely to be higher than the upper edge of the scraping bar 23, and the sharp end of the impurity may touch the surface of the heat sink 5. At this time, the receiving plate 7 continues to drive the impurities to rise, and the sharp end of the impurity will still scratch the surface of the heat sink 5, causing the surface of the heat sink 5 to be scratched. Therefore, in order to avoid this situation, when the receiving plate 7 moves upward, the transmission rod 31 will intermittently contact with multiple protrusions 30. When the transmission rod 31 contacts the protrusions 30, the transmission rod 31 will move away from the receiving plate 7. At this time, the connecting rod 35 drives the push plate 22 to slide on the limit rod 24, and the two push plates 22 on the same receiving plate 7 approach each other, pushing the impurities at the edge of the receiving plate 7 to the middle of the receiving plate 7, so that the impurities are away from the surface of the heat sink 5. After the transmission rod 31 passes the protrusion 30, it will Under the action of spring 28, the receiving plate 7 is reset. Each time the receiving plate 7 moves a certain distance, the push plate 22 pushes the impurities, thereby preventing the impurities from sliding along the scraper 23. As the impurities accumulate at the edge of the receiving plate 7, the impurities are higher than the upper edge of the scraper 23, and the sharp ends of the impurities contact the surface of the heat sink 5. As the receiving plate 7 continues to drive the impurities upward, the sharp ends of the impurities scrape against the surface of the heat sink 5, causing scratches on the surface of the heat sink 5. In addition, the multiple movements of the push plate 22 are not driven by electricity, which helps save electricity. In addition, when the push plate 22 moves toward the middle of the receiving plate 7, the scraper 23 is always in contact with the surface of the heat sink 5 under the action of spring 1 27. This prevents the push plate 22 and scraper 23 from simultaneously moving away from the inner wall of the heat sink 5, resulting in a gap between the push plate 22 and scraper 23 and the heat sink 5, which would allow impurities to enter the gap and affect the subsequent normal operation of the push plate 22 and scraper 23. When the receiving plate 7 is turned over to remove impurities on its surface, the impurities may have strong adhesion and be difficult to fall off. Therefore, to avoid this situation, the motor 3 19 drives the connecting rod 1 20 to rotate, and the telescopic rod 15 is reciprocated under the action of the connecting rod 21, thereby causing the receiving plate 7 to vibrate. The vibration can accelerate the removal of impurities from the receiving plate 7, avoiding the situation where impurities remain on the surface of the receiving plate 7 and affect its subsequent use. The solar panel 4 can convert solar energy into electrical energy and provide power for the anti-scratch impurity removal component to ensure its stable and continuous operation.
