Abstract

It solves the problem that existing low-loss heat dissipation structures have fixed heat dissipation structures, making it difficult to identify wind direction and assist in delivering air to the equipment for auxiliary heat dissipation and power reduction. The invention includes a base, a transformer body, and a heat dissipation mechanism. The heat dissipation mechanism includes a shell, a filter screen, a drive ring, a rotating rod, fan blades, a sensing element, and a control element. This invention uses the heat dissipation mechanism to drive the drive ring, causing the fan blades to rotate continuously.

In addition, it can assist in scraping away impurities on the outer wall of the filter screen while the fan blades switch angles.

Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer with a low-loss heat dissipation structure. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Currently, even low-loss transformers can experience high temperatures during prolonged operation. Excessive temperature reduces the transformer's operating efficiency and output stability. Especially in hot summers, high temperatures can even lead to spontaneous combustion of the transformer. To improve heat dissipation in low-loss transformers, ventilation holes are usually opened on the side of the transformer, and a cooling fan is installed inside to enhance heat dissipation.

[0003] However, the existing heat dissipation structure and the position of the heat dissipation holes are relatively fixed. During use, heat dissipation is mainly achieved through its own fan structure, making it difficult to utilize external airflow, resulting in relatively high energy consumption. When the exhaust position is opposite to the wind direction, the resistance to gas exhaust inside the machine increases, reducing heat dissipation efficiency. In order to improve the efficiency of automatic reception of external wind force during the heat dissipation process and promote auxiliary heat dissipation of the internal structure of the transformer, a transformer with a low-loss heat dissipation structure is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a transformer with a low-loss heat dissipation structure that facilitates automatic sensing of wind direction and automatically inputs gas from the direction of wind into the device for heat dissipation during the heat dissipation process, and outputs it from the direction of wind departure, thereby reducing the power consumption of the device, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transformer with a low-loss heat dissipation structure, comprising a base and a heat dissipation mechanism. A transformer body is fixedly connected to the base. The heat dissipation mechanism includes a housing and a filter screen fixedly mounted on the base. Both the housing and the filter screen are cylindrical. A drive ring is rotatably connected to the base. Multiple sets of rotating rods are uniformly rotatably connected to the upper side of the drive ring. Fan blades are fixedly connected to the rotating rods. A sensing element for sensing wind direction is provided on the upper side of the transformer body. A device for controlling the swing of the fan blades according to the wind direction is also provided on the upper side of the transformer body. The control component for the swing angle allows the heat dissipation mechanism to drive the drive ring, causing the fan blades to rotate continuously. The control component adjusts the swing angle of the fan blades according to the wind direction, so that when the fan blades rotate on the incoming wind side, they can help deliver air to the area around the transformer body. When rotating to the outgoing wind side, the swing direction of the fan blades is adjusted to generate a reverse thrust, which helps to exhaust the hot air around the transformer body outward and output it according to the wind direction. This facilitates automatic sensing of the wind direction and automatically inputting gas into the equipment from the incoming wind direction for heat dissipation during the heat dissipation process, and outputting it from the outgoing wind direction, thereby reducing the power consumption of the equipment.

The first pushing block, the second pushing block, the third pushing block and the fourth pushing block are evenly spaced and can all mesh with the driving groove. The rotating ring is provided with a limiting component for assisting in limiting the rotation angle of the driving disk, so as to facilitate the control of the rotation angle of the driving disk.

[0009] Preferably, the sensing element includes a top cover fixedly installed above the housing, a wind direction sensor fixedly connected to the top of the top cover, a first motor fixedly connected inside the top cover, a first gear fixedly connected to the output end of the first motor on the same axis, and a first internal gear ring fixedly connected to the inner wall of the rotating disk. The first internal gear ring meshes with the first gear to facilitate the sensing of wind direction.

[0010] Preferably, the limiting component includes a guide frame fixedly installed on the rotating ring, a limiting block slidably connected inside the guide frame, one end of the limiting block being arc-shaped and capable of being inserted into the drive groove, and a spring fixedly connected to the limiting block and the guide frame, which facilitates limiting the rotation angle of the drive disk.

[0012] Preferably, the connecting plate is provided with an indicator arrow, which is located between the first push block and the fourth push block. The tip of the indicator arrow is used to point in the direction of the wind, so as to facilitate the indication of the direction of the wind.

[0013] Preferably, the housing has multiple sets of heat dissipation grooves evenly distributed on it to facilitate the entry and exit of gas.

[0014] Preferably, the top surface of the top cover is conical to reduce dust residue above.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention provides a transformer with a low-loss heat dissipation structure, which solves the problem that existing low-loss heat dissipation transformers have fixed heat dissipation structure positions, making it difficult to identify wind direction and assist in delivering air to the equipment for auxiliary heat dissipation and power reduction. The heat dissipation mechanism drives the drive ring to make the fan blades rotate continuously, and the control component controls the swing angle of the fan blades according to the wind direction. When the fan blades rotate on the windward side, they can assist in sending air into the area around the transformer body.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-13 This invention provides a technical solution: a transformer with a low-loss heat dissipation structure, including a base 1 and a heat dissipation mechanism 3. A transformer body 2 is fixedly connected to the base 1. Multiple sets of heat dissipation grooves 37 are evenly opened on the housing 4. The heat dissipation mechanism 3 includes a housing 4 and a filter screen 5 fixedly installed on the base 1. Both the housing 4 and the filter screen 5 are cylindrical. A drive ring 6 is rotatably connected to the base 1. Multiple sets of rotating rods 7 are evenly rotatably connected to the upper side of the drive ring 6. Fan blades 8 are fixedly connected to the rotating rods 7. A sensing element 9 for sensing wind direction is provided on the upper side of the transformer body 2. A control element 10 for controlling the swing angle of the fan blades 8 according to the wind direction is provided on the upper side of the transformer body 2. The heat dissipation mechanism 3 can drive the drive ring 6 to make the fan blades 8 rotate continuously, and control the swing angle of the fan blades 8 according to the wind direction through the control element 10. When the fan blades 8 rotate on the windward side, they can help send air into the area around the transformer body 2. When rotating to the windward side, the swing direction of the fan blades 8 is adjusted to generate a reverse thrust, which helps to discharge the hot air around the transformer body 2 outward and output it with the wind direction.

[0033] The control component 10 includes a support mesh 11 fixedly installed on the upper side of the base 1. The filter mesh 5 is attached to and fixed to the outer wall of the support mesh 11. The inner wall of the drive ring 6 is attached to and rotates with the outer wall of the filter mesh 5. The outer wall of the drive ring 6 is rotatably attached to the inner wall of the housing 4. A rotating ring 12 is rotatably connected to the inner wall of the top of the housing 4. A rotating rod 7 passes through the rotating ring 12 and is rotatably connected to the rotating ring 12. An adjusting component 13 for adjusting the rotation angle of the rotating rod 7 is provided on the upper side of the housing 4.

[0034] The adjusting component 13 includes a drive disk 14 coaxially fixedly connected to the top of the rotating rod 7. Five sets of drive grooves 15 are evenly opened on the drive disk 14. The upper end of the support net 11 is rotatably connected to a rotating disk 16. A connecting disk 17 is fixedly connected to the upper side of the rotating disk 16. An indicator arrow 36 is provided on the connecting disk 17. The indicator arrow 36 is located between the first push block 20 and the fourth push block 23. The tip of the indicator arrow 36 is used to point to the direction of the wind. A connecting ring 18 is fixedly connected to the bottom of the connecting disk 17. The bottom surface of the connecting ring 18 is rotatably connected to the top of the housing 4. The rotating disk 16 and the connecting ring 18 are provided with pushers 19 for controlling the rotation angle of the drive disk 14.

[0035] The pusher 19 includes a first pusher block 20 and a second pusher block 21 fixedly installed on the inner wall of the connecting ring 18. A third pusher block 22 and a fourth pusher block 23 are fixedly connected to the outer wall of the rotating disk 16. The first pusher block 20, the second pusher block 21, the third pusher block 22 and the fourth pusher block 23 are evenly spaced and can all mesh with the drive groove 15. The rotating ring 12 is provided with a limiting member 24 for assisting in limiting the rotation angle of the drive disk 14.

[0036] The sensing element 9 includes a top cover 25 fixedly installed on the top of the housing 4. The top surface of the top cover 25 is conical. A wind direction sensor 26 is fixedly connected to the top of the top cover 25. A first motor 27 is fixedly connected inside the top cover 25. A first gear 28 is coaxially fixedly connected to the output end of the first motor 27. A first internal gear ring 29 is fixedly connected to the inner wall of the rotating disk 16. The first internal gear ring 29 meshes with the first gear 28.

[0037] The limiting component 24 includes a guide frame 30 fixedly installed on the rotating ring 12, a limiting block 31 slidably connected inside the guide frame 30, one end of the limiting block 31 is arc-shaped and can be inserted into the drive groove 15, and a spring 32 fixedly connected to the limiting block 31 and fixedly connected to the guide frame 30.

[0038] The heat dissipation mechanism 3 also includes a second motor 33 fixedly mounted on the base 1. The output end of the second motor 33 is coaxially fixedly connected to a second gear 34. The bottom end of the drive ring 6 is coaxially fixedly connected to a second internal gear ring 35, which can mesh with the second gear 34.

[0039] This implementation plan stipulates that the appendix Figure 4 The rotating disk 16 rotates clockwise for forward rotation and counterclockwise for reverse rotation. During use, the wind direction sensor 26 senses the direction of the wind and controls the first motor 27 to drive the first gear 28 to rotate, which in turn causes the first internal gear ring 29 to drive the rotating disk 16 to rotate. The rotating disk 16 drives the connecting disk 17 and the connecting ring 18 to rotate, adjusting the positions of the first push block 20, the second push block 21, the third push block 22, and the fourth push block 23 so that the tip of the indicator arrow 36 points in the direction of the wind. During this process, the second motor 33 continuously drives the second gear 34 to rotate, which in turn drives the second internal gear ring 35 to rotate, which in turn causes the drive ring 6 to rotate. The drive ring 6 drives the upper rotating rod 7 and the fan blade 8 to rotate synchronously around the axis of the drive ring 6.

[0040] When the drive disk 14 is positioned between the first push block 20 and the second push block 21, one side of the fan blade 8 points towards the axis of the drive ring 6. At this time, the edge of the fan blade 8 can adhere to the outer wall of the filter screen 5, scraping away dust and impurities from the outer wall of the filter screen 5 and assisting in cleaning the filter screen 5. When the drive disk 14 passes the second push block 21, the second push block 21 will first engage in the drive groove 15 and then push the drive disk 14 to rotate one notch in the opposite direction, causing the limit block 31 to slide out of the current drive groove 15 and engage in the next set of drive grooves 15 for limiting. At this time, the drive disk 14 drives the rotating rod 7 and the fan blade 8 to rotate at a set angle to complete the adjustment, so that when the fan blade 8 swings to the side of the outward airflow, it can push the gas in the outward airflow direction, assisting in outputting the hot air around the transformer body 2 inside the housing 4. At this time, the edge of the fan blade 8 no longer adheres to the outer wall of the filter screen 5.

[0041] When the drive disk 14 rotates to the third push block 22, it receives the thrust from the third push block 22, causing the drive disk 14 to rotate one notch clockwise until the limit block 31 engages in the adjacent drive groove 15 and is then stopped again. At this time, the fan blade 8 points to the axis of the drive ring 6 again, and the edge of the fan blade 8 is once again in contact with the outer wall of the filter screen 5, assisting in scraping away impurities from the outer wall of the filter screen 5. When the drive disk 14 rotates to the position of the fourth push block 23, the fourth push block 23 pushes the drive disk 14 to rotate one notch clockwise, and the limit block 31 engages in the adjacent drive groove 15 and is then stopped again. At this time, the tilt direction of the fan blade 8... Opposite to the tilting direction of the opposite side fan blade 8, as the fan blade 8 rotates clockwise along with the drive ring 6, it pushes the gas through the inner wall to the filter screen 5. After being filtered by the filter screen 5, the gas is delivered to the area around the transformer body 2, which improves the heat dissipation efficiency and prevents the gas delivery direction from being opposite to the wind direction. Finally, when the drive disk 14 rotates to the first push block 20 again, the first push block 20 pushes the drive disk 14 to rotate counterclockwise by one notch. After the drive slot 15 releases from contact with the first push block 20, the limit block 31 slides into the adjacent drive slot 15 and limits it again. Thus, the fan blade 8 completes one cycle of switching.

[0042] It is worth noting that by repeating the above steps, when the fan blade 8 rotates to the incoming air direction, it draws air into the support mesh 11 through the heat dissipation slot 37. When it rotates to the outgoing air direction, it automatically changes the tilt angle of the fan blade 8 to help expel the hot air inside the support mesh 11, thereby improving the airflow efficiency and reducing energy consumption. This structure can also assist in scraping away impurities on the outer wall of the filter mesh 5 while the fan blade 8 is switching angles, and then expel them with the wind, thereby improving the efficiency and service life of the filter mesh 5. When the wind direction changes, the device can automatically sense the change in wind direction through the wind direction sensor 26 and control the operation of the first motor 27 so that the indicator arrow 36 always points to the direction of the wind, thus controlling the switching position of the fan blade 8.

[0043] Please see the appendix Figure 13 The device can also adjust the swing angle of the fan blade 8 by coaxially setting a third gear 38 on the rotating rod 7 and setting an electric telescopic rod 39 on the rotating ring 12. The rack 40 set at the output end of the electric telescopic rod 39 meshes with the third gear 38 to rotate, thereby adjusting the swing angle of the fan blade 8. In this case, it is not necessary to set the first push block 20, the second push block 21, the third push block 22 and the fourth push block 23, reducing the impact wear of the drive disc 14. However, this structure requires a large number of electric telescopic rods 39 and will consume more energy during use, which will increase the production and use costs. This structure only provides one alternative embodiment. Similarly, other drive methods can be used for control and drive, which will not be listed here.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
