[0001] This utility model relates to the field of transformer technology, specifically to a transformer fan fixing component and a transformer using the same. Background Technology

[0002] Dry-type transformers are a type of transformer commonly used in lighting applications such as buildings and airports due to their high safety, low loss, and small size. Dry-type transformers utilize air cooling for heat dissipation; several fans are mounted on a fixed frame at the bottom, driving airflow.

[0003] However, in existing dry-type transformers, the fan is fixed to the fixed unit by multiple bolts, which involves many steps and takes a long time to install. It is also time-consuming and laborious to replace and disassemble, which is extremely inconvenient. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a transformer fan fixing component and a transformer using the same.

[0005] The technical solution of this utility model is as follows:

[0006] A transformer fan mounting assembly is installed on a transformer mounting frame and includes a rectangular frame-shaped housing. A mounting port is provided on one side near the mounting frame for the fan to slide into the housing through the mounting port.

[0007] Rotating parts are provided on both sides of the lower edge of the mounting port, and the housing can be rotatably connected to the fixed frame through the rotating parts and rotate vertically;

[0008] The upper edge of the mounting port is provided with hook parts on both sides, and the mounting bracket is provided with a slot that mates with the hook parts;

[0009] A pushing mechanism is provided on the side of the casing away from the installation port, which is used to push the fan to slide towards the installation port.

[0010] In the above scheme, the jacking mechanism includes a rotating rod that is rotatably connected to the housing, a cam fixed on the rotating rod, and a drive component that controls the rotation of the rotating rod.

[0011] Furthermore, the driving component is a worm gear, which is rotatably connected to the housing, and a turbine is provided on the rotating rod, which is connected to the worm gear.

[0012] Preferably, the cam includes multiple protrusions, with the protrusion lengths of each protrusion increasing sequentially.

[0013] Preferably, the multiple protrusions are evenly arranged along the circumference of the cam.

[0014] Preferably, the cam includes three protrusions.

[0017] This application also provides a transformer, including the above-mentioned transformer fan fixing assembly, and further including a fixing frame, a transformer body and a fan fixed on the fixing frame, wherein the fixing frame has a connecting lug protruding in the direction of the transformer housing, and the rotating part is rotatably connected to the connecting lug.

[0018] To prevent the transformer housing from being affected by mounting plates or brackets used for transformer installation when rotating, the connecting lugs are provided with vertical grooves. The rotating part cooperates with the vertical grooves, allowing it to rotate and slide vertically.

[0019] This utility model provides a transformer fan fixing component and a transformer using the same.

[0026] Example 1

[0027] like Figure 1 and Figure 2As shown, this utility model embodiment provides a transformer fan fixing assembly (hereinafter referred to as the fan fixing assembly), which is installed on the fixing frame 2 of the transformer. The transformer and the fixing frame 2 included therein are existing structures and will not be described in detail here.

[0028] The fan mounting assembly includes a rectangular frame-shaped housing 11. A mounting port 111 is located on one side near the mounting frame 2, allowing the fan 4 to slide into the housing 11 through the mounting port 111. Rotating parts 112 are located on both sides of the lower edge of the mounting port 111, enabling the housing 11 to be rotatably connected to the mounting frame 2 via the rotating parts 112 and to rotate vertically. Hook parts 113 are located on both sides of the upper edge of the mounting port 111, and the mounting frame 2 has slots 21 that engage with the hook parts 113.

[0029] A pushing mechanism 12 is provided on the side of the housing 11 away from the mounting port 111, which is used to push the fan 4 to slide towards the mounting port 111.

[0030] Specifically, such as Figure 2 As shown, the housing 11 can be welded from angle steel, and its internal dimensions match the dimensions of the fan 4. The fan 4 is slidably installed into the housing 11 from the mounting port 111 and is locked inside the housing 11, only able to slide towards or away from the mounting port 111. After the fan 4 is installed into the housing 11, its air intake is close to the mounting port 111.

[0031] Multiple housings 11 can be provided according to the number of fans 4 required. The length of the housing 11 can also be extended, and multiple accommodating sections can be set inside it to accommodate multiple fans 4 at the same time, so that multiple fans 4 can be directly fixed through a housing 11. In this embodiment, for ease of understanding, only accommodating a single fan 4 is taken as an example.

[0032] The jacking mechanism 12 specifically includes a rotating rod 121 rotatably connected to the housing 11, a cam 122 fixed on the rotating rod 121, and a drive component 123 for controlling the rotation of the rotating rod 121. The rotating shaft of the rotating rod 121 is parallel to the mounting port 111, and in this embodiment, it is horizontally positioned. When the rotating rod 121 rotates, it drives the cam 122 to rotate, thereby pressing the fan 4 installed in the housing 11 onto the transformer's mounting frame 2, achieving the purpose of quickly fixing the fan 4.

[0033] In this embodiment, the drive component 123 adopts a worm gear structure and is rotatably connected to the housing 11. Correspondingly, a turbine is provided on the rotating rod 121, which is connected to the worm gear. By rotating the worm gear, the rotation of the rotating rod 121 is controlled.

[0034] The cam 122 is preferably located at the center of the side of the housing 11 away from the mounting port 111.

[0035] Please combine Figure 3As shown, in order to achieve a better propulsive effect, the cam 122 preferably includes multiple protrusions, each protrusion having an increasing length and being evenly arranged along the circumference of the cam 122 to press against the fans 4 of different sizes. In this embodiment, the cam 122 includes three protrusions.

[0036] Understandably, when pressing the fan 4, the optimal pressing point is located at the center of the side of the fan 4 away from the mounting port 111. If it deviates from this center position, the point of force application will be offset. Although the fan 4 can still be pressed, the offset of the point of force application will generate torque force, which will increase the sliding friction force between the fan 4 and the housing 11 when the fan 4 is pushed to move, making the fan 4 difficult to push.

[0037] While a single, relatively long protrusion can achieve the purpose of pressing and compressing fans 4 of different sizes, the larger the size of the fan 4, the further the pressing point between the protrusion and the fan 4 will be from the center of the fan 4. The cam 122 with multiple protrusions can select protrusions of different extension lengths to press and compress the fan 4 according to the size of the fan 4, so as to make the pressing point between the protrusion and the fan 4 as close as possible to the center of the fan 4.

[0038] In order to better drive the fan 4, a pusher plate 13 is also slidably provided inside the housing 11. It is located on the side of the pusher mechanism 12 near the mounting port 111 and can slide towards or away from the mounting port 111. Through the pusher plate 13, the thrust of the cam 122 is evenly distributed on the pusher plate 13. The pusher plate 13 then pushes the fan 4 horizontally, improving the smoothness of the fan 4 when it is pushed and slid, while protecting the fan 4.

[0039] The push pad 13 preferably includes two, arranged parallel to each other, with a spring between them. When the fan 4 is pressed, the spring acts as a buffer to prevent excessive pressing force from damaging the fan 4.

[0040] Usage process description: When using the fan fixing assembly, rotate the housing 11 so that the mounting port 111 faces upward, and insert the fan 4 through the mounting port 111. Then rotate the housing 11 to lock and fix it with the transformer fixing frame 2. Then push the fan 4 through the jacking mechanism 12 to press the fan 4 onto the fixing frame 2, thereby completing the fixing of the fan 4.

[0041] The fan fixing assembly provided in this embodiment makes fixing the fan 4 simpler and more convenient, saves the time of loading and unloading the fan 4, and improves the efficiency of operation.

[0042] Example 2

[0043] like Figure 1 As shown, this application also provides a transformer, including several of the aforementioned fan mounting components. The transformer also includes a mounting frame 2, a transformer body 3 fixed on the mounting frame 2, and several fans 4.

[0044] Several fans 4 are respectively installed in several fan fixing components. The fan fixing components are divided into two groups and symmetrically connected to both sides of the fixing frame 2. The fan fixing components in each group are arranged horizontally side by side.

[0045] Among them, the fixed frame 2 also has a connecting ear 22 protruding in the direction of the housing 11, and the rotating part 112 is rotatably connected to the connecting ear 22.

[0046] In addition, when the housing 11 rotates, it may be interfered with by objects that may exist below, such as the mounting plate used to install the transformer. To avoid this problem, the connecting ear 22 is provided with a vertical groove 221. The rotating part 112 cooperates with the vertical groove 221 and can rotate and slide vertically.

[0047] When installing the fan 4, rotate the housing 11 while simultaneously sliding the rotating part 112 towards the upper end of the vertical groove 221. At this time, the housing 11 will move upward a certain distance, reducing the impact of objects that may be present below on the housing 11. When fixing the fan 4, rotate the housing 11 while simultaneously sliding the rotating part 112 towards the lower end of the vertical groove 221, so that the fan 4 corresponds with the fixing frame 2 and is pressed tightly onto the fixing frame 2.
