Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and in particular relates to an adjustable air outlet device for a dry-type transformer fan. Background Technology

[0002] The main function of the fan in a dry-type transformer is to help dissipate heat and cool the transformer by forcing air circulation, preventing equipment damage caused by overheating, ensuring its normal operation and extending its service life, and reducing accidents caused by excessive temperature. The forced air cooling fan is usually installed under the coil of the dry-type transformer, and then blows the cold air directly into the coil of the transformer to carry away the heat inside the coil, which greatly improves the heat dissipation effect.

[0003] To ensure a safe air gap, the fan of a 20KV or 35KV dry-type transformer is generally far from the high-voltage coil. This results in most of the airflow being blocked by the lower clamp of the transformer, preventing it from reaching the high and low voltage coils. To overcome the shortcomings of the prior art, this utility model provides an adjustable air outlet device for a dry-type transformer fan, which can freely adjust the bracket angle according to the actual situation to meet the fan's airflow requirements at various angles to the high and low voltage coils. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an adjustable air outlet device for dry transformer fans.

[0005] The technical solution adopted by this utility model is as follows: an adjustable air outlet device for a dry transformer fan, including a transformer, on which two sets of support frames are symmetrically installed. On the opposite side walls of each set of support frames, multiple sets of mounting frames for adjusting the direction of the fan are installed. A fan fixing frame is installed on the mounting frame, and a fan for cooling is installed on the fan fixing frame. A lifting component is also installed on the bottom wall of the fan fixing frame, and the lifting component is located between the two sets of support frames.

[0006] The mounting bracket is provided with a fixing hole and multiple sets of limiting holes for positioning, and the multiple sets of limiting holes are distributed in a fan shape with the fixing hole as the center.

[0007] The support frame has a second fixing hole and a second limiting hole for limiting. Both the second fixing hole and the second limiting hole penetrate the support frame. The first fixing hole and the second fixing hole are connected through each other. The second limiting hole is connected through each other to the first limiting hole in the middle position.

[0008] A fixing rod is movably installed on the fixing hole one, and the fixing rod passes through the mounting frame and the support frame in sequence. A fixing member is movably installed on the limiting hole one, which is connected to the limiting hole two, and the fixing member passes through the adjacent mounting frame and the support frame in sequence, so as to facilitate the fixing of the angle of the mounting frame.

[0009] When the angle of the fan outlet needs to be adjusted, first pull the lifting assembly out of the bottom wall of the fan mounting bracket. Then, remove the fixing parts from the limiting holes 1 and 2 in sequence. Then, lift the fan mounting bracket using the lifting assembly. The fan mounting bracket rotates around the fixing rod as the rotation center, either lifting up or pressing down. If the fan mounting bracket is lifted, the lowest limiting hole 1 rotates to the position of the original center limiting hole 1. At this time, the lowest limiting hole 1 and limiting hole 2 are connected. Then, the fixing parts are inserted into the limiting holes 1 and 2 in sequence to fix the fan. If the fan mounting bracket is lowered, the highest limiting hole 1 rotates to the position of the original center limiting hole 1. At this time, the highest limiting hole 1 and limiting hole 2 are connected. Then, the fixing parts are inserted into the limiting holes 1 and 2 in sequence to fix the fan.

[0010] Furthermore, the lifting assembly includes a fixed frame located on the bottom wall of the fan mounting bracket. Two sets of telescopic rods are symmetrically installed inside the fixed frame. Lifting rods are installed at the ends of the telescopic rods and are located outside the fixed frame. When the position of the fan outlet needs to be adjusted, the lifting rods are pulled out. By utilizing the lever principle, the lifting or pressing force can be reduced. After use, the lifting rods can be directly pushed to compress the telescopic rods, which is convenient and quick.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows: When the fan angle is not suitable, the mounting bracket can be rotated by the fixing rod to change the fan angle. This method not only enables the fan to meet various blowing angles and makes the bracket universal, but also improves the output effect of the fan air volume and allows the heat of the transformer to be effectively controlled during operation.

[0021] like Figures 1-5 As shown, an adjustable air outlet device for a dry-type transformer fan includes a transformer 1. Two sets of support frames 2 are symmetrically installed on the base of the transformer 1. Multiple sets of mounting frames 3 for adjusting the direction of the fan 5 are installed on the opposite side walls of each set of support frames 2. A fan fixing frame 4 is installed on the mounting frame 3. A fan 5 for cooling is installed on the fan fixing frame 4. A lifting component is also installed on the bottom wall of the fan fixing frame 4. The lifting component is located between the two sets of support frames 2.

[0022] The mounting bracket 3 is provided with a fixing hole 6 and multiple sets of limiting holes 7 for limiting, and the multiple sets of limiting holes 7 are distributed in a fan shape with the fixing hole 6 as the center.

[0023] The support frame 2 has a second fixing hole 8 and a second limiting hole 9 for limiting. The second fixing hole 8 and the second limiting hole 9 are both provided through the support frame 2. The first fixing hole 6 and the second fixing hole 8 are connected through each other. The second limiting hole 9 is connected through each other to the first limiting hole 7 in the middle position.

[0024] A fixing rod 10 is movably installed on the fixing hole 6. The fixing rod 10 passes through the mounting frame 3 and the support frame 2 in sequence. A fixing member 11 is movably installed on the limiting hole 7, which is connected to the limiting hole 9 in sequence. The fixing member 11 passes through the adjacent mounting frame 3 and the support frame 2 in sequence, so as to facilitate the fixing of the angle of the mounting frame 3.

[0025] The lifting assembly includes a fixed frame 12, which is located on the bottom wall of the fan mounting frame 4. Two sets of telescopic rods 13 are symmetrically installed inside the fixed frame 12. Lifting rods 14 are installed at the ends of the telescopic rods 13 and are located outside the fixed frame 12.

[0026] In practical use, when it is necessary to adjust the angle of the air outlet of the fan 5, firstly, pull out the lifting rod 14, then remove the fixing part 11 from the limiting hole 7 and the limiting hole 9 in sequence, and then lift the fan mounting frame 4 by lifting the lifting rod 14. Utilizing the lever principle, the lifting or pressing force can be reduced. The fan mounting frame 4 rotates around the fixing rod 10 as the rotation center, or is lifted or pressed down. If the fan mounting frame 4 is lifted, the lowermost limiting hole 7 rotates to the position of the limiting hole 7 at its original center position. At this time, the lowermost... Limiting hole 7 and limiting hole 9 are connected through each other. Then, the fixing piece 11 is inserted into the limiting hole 7 and limiting hole 9 in sequence to fix the fan 5. When the fan fixing frame 4 moves down, the uppermost limiting hole 7 rotates to the position of the limiting hole 7 at the original center position. At this time, the uppermost limiting hole 7 and limiting hole 9 are connected through each other. Then, the fixing piece 11 is inserted into the limiting hole 7 and limiting hole 9 in sequence to fix the fan 5. After use, the lifting rod 14 is pushed directly, and the telescopic rod 13 is compressed, which is convenient and quick.
