Description
Technical Field
[0001] The utility model relates to the field of transformer noise reduction equipment, in particular to a noise reduction device for a transformer. Background Technique
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage, current, and impedance; it consists of an iron core (or magnetic core) and coils, where the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils; transformers play a crucial role in the power system and are widely used in industries, agriculture, transportation, urban communities, etc., and their classifications and applications are also very rich.
[0003] When a transformer is installed and used, due to the electromagnetic vibration and mechanical resonance inside it, the transformer will generate noise. Thus, when the transformer is installed near residents, the noise of the transformer will affect the normal rest and life of the surrounding residents. Therefore, it is particularly important to carry out noise reduction treatment on the transformer, so there is an urgent need for a device to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a noise reduction device for a transformer to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A noise reduction device for a transformer, including a transformer main body, a first sound insulation board, and a second sound insulation board. A splicing mechanism for convenient mutual splicing is arranged between the first sound insulation board and the second sound insulation board. A fixing mechanism for conveniently fixing the first sound insulation board is arranged on the first sound insulation board. The splicing mechanism includes a first fixing block, a movable plate, a first limiting block, a perforation, a second limiting block, a movable shaft, a second fixing block, a fixing ring, and a rubber ring. The first fixing block is fixed on one side of the second sound insulation board. The movable plate is slidably arranged inside the first fixing block. The perforation is opened on one side of the movable plate. The first limiting block is fixed on the movable plate. The second fixing block is fixed on one side of the first sound insulation board. The movable shaft is movably inserted through the center position of the second fixing block. The second limiting block is fixed on the outer side of the movable shaft. The fixing ring is fixedly arranged around the outer side of the movable shaft. The rubber ring is adhesively fixed on one side of the fixing ring. When in use, the first sound insulation board and the second sound insulation board are mutually spliced, then the movable plate is slid, and then the movable shaft is slid, so that the movable shaft drives the second limiting block to pass through the perforation position. Then the movable shaft is rotated to make the perforation and the second limiting block misaligned, so that the first sound insulation board and the second sound insulation board are fixed. The first sound insulation board and the second sound insulation board are used for sound insulation work to reduce noise pollution. At the same time, when fixing, the rubber ring is in a deformed state at this time, so the rubber ring has a tendency to reset, making the second limiting block closely attached to the outer surface of the movable plate, and fixing the position of the second limiting block through friction.
[0006] Preferably, the fixing mechanism includes a screw rod and an extrusion plate. The screw rod is inserted through the center position of the first sound insulation board by means of threads. An extrusion plate is fixedly arranged on one side of the screw rod, and a rotating block for conveniently rotating the screw rod is fixedly arranged on the other side of the screw rod. After the first sound insulation board and the second sound insulation board are assembled, at this time, rotate the screw rod to drive the extrusion plate to move until the extrusion plate closely adheres to the outer side of the transformer body. In this way, the positions of the first sound insulation board and the second sound insulation board are fixed by the frictional force between the extrusion plate and the transformer body.
[0007] Preferably, there are two first sound insulation boards and two second sound insulation boards, and they are assembled with each other to form a rectangle and surround the outer side of the transformer body.
[0008] Preferably, there are two first limit blocks, which are respectively fixed on both sides of the first fixing block to prevent the movable plate from detaching from the first fixing block.
[0009] Preferably, there are two second limit blocks, which are symmetrically fixed on both sides of the movable shaft.
[0010] Preferably, the cross-section of the second limit block cooperating with the movable shaft has the same shape as the perforation.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] When the present utility model is in use, the first sound insulation board and the second sound insulation board are assembled with each other, then the movable plate is slid, and then the movable shaft is slid, so that the movable shaft drives the second limit block to pass through the perforation position. Then, the movable shaft is rotated to make the perforation and the second limit block misaligned. In this way, the first sound insulation board and the second sound insulation board are fixed, and the first sound insulation board and the second sound insulation board are used for sound insulation work to reduce noise pollution. At the same time, when it is fixed, the rubber ring is in a deformed state at this time. In this way, the rubber ring has a reset tendency, so that the second limit block closely adheres to the outer surface of the movable plate, and the position of the second limit block is fixed by the frictional force;
[0013] After the first sound insulation board and the second sound insulation board are assembled, at this time, rotate the screw rod to drive the extrusion plate to move until the extrusion plate closely adheres to the outer side of the transformer body. In this way, the positions of the first sound insulation board and the second sound insulation board are fixed by the frictional force between the extrusion plate and the transformer body.

Specific implementation manners
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0020] Please refer to Figures 1-4, the utility model provides a noise reduction device for a transformer, which includes a transformer main body 1, a first sound insulation board 2 and a second sound insulation board 3. There are two first sound insulation boards 2 and two second sound insulation boards 3, and they are mutually joined to form a rectangle, surrounding the outside of the transformer main body 1. There is a joining mechanism between the first sound insulation board 2 and the second sound insulation board 3 to facilitate mutual joining, and there is a fixing mechanism on the first sound insulation board 2 to facilitate fixing the first sound insulation board 2. The joining mechanism includes a first fixing block 6, a movable plate 7, a first limiting block 8, a perforation 9, a second limiting block 11, a movable shaft 10, a second fixing block 12, a fixing ring 13 and a rubber ring 14. The first fixing block 6 is welded and fixed on one side of the second sound insulation board 3. The movable plate 7 slides inside the first fixing block 6. The perforation 9 is opened on one side of the movable plate 7. The first limiting block 8 is welded and fixed on the movable plate 7. There are two first limiting blocks 8, which are respectively fixed on both sides of the first fixing block 6 to prevent the movable plate 7 from detaching from the first fixing block 6. The second fixing block 12 is welded and fixed on one side of the first sound insulation board 2. The movable shaft 10 is movably inserted through the center of the second fixing block 12. The second limiting block 11 is welded and fixed on the outside of the movable shaft 10. There are two second limiting blocks 11, which are symmetrically fixed on both sides of the movable shaft 10. The cross-section of the cooperation between the second limiting block 11 and the movable shaft 10 is the same as the shape of the perforation 9. The fixing ring 13 is welded and fixed around the outside of the movable shaft 10. The rubber ring 14 is adhesively fixed on one side of the fixing ring 13. When in use, the first sound insulation board 2 and the second sound insulation board 3 are mutually joined, then the movable plate 7 is slid, and then the movable shaft 10 is slid, so that the movable shaft 10 drives the second limiting block 11 to pass through the position of the perforation 9. Then the movable shaft 10 is rotated so that the perforation 9 and the second limiting block 11 are misaligned, so that the first sound insulation board 2 and the second sound insulation board 3 are fixed. The first sound insulation board 2 and the second sound insulation board 3 are used for sound insulation work to reduce noise pollution. At the same time, when fixing, the rubber ring 14 is in a deformed state at this time. In this way, the rubber ring 14 has a reset tendency, so that the second limiting block 11 is closely attached to the outer surface of the movable plate 7, and the position of the second limiting block 11 is fixed by friction.
[0021] The fixing mechanism includes a screw 4 and an extrusion plate 5. The screw 4 is inserted through the center of the first sound insulation board 2 by threads. One side of the screw 4 is fixed with an extrusion plate 5 by a bolt. The other side of the screw 4 is welded and fixed with a turning block to facilitate turning the screw 4. After the first sound insulation board 2 and the second sound insulation board 3 are joined, at this time, the screw 4 is rotated to drive the extrusion plate 5 to move until the extrusion plate 5 is closely attached to the outside of the transformer main body 1. In this way, the positions of the first sound insulation board 2 and the second sound insulation board 3 are fixed by the friction between the extrusion plate 5 and the transformer main body 1.
[0022] Working principle: When in use, the first sound insulation board 2 and the second sound insulation board 3 are joined together, then the movable board 7 is slid, and then the movable shaft 10 is slid, so that the movable shaft 10 drives the second limit block 11 to pass through the perforation 9. Then the movable shaft 10 is rotated to misalign the perforation 9 and the second limit block 11, so that the first sound insulation board 2 and the second sound insulation board 3 are fixed. The first sound insulation board 2 and the second sound insulation board 3 are used for sound insulation work to reduce noise pollution. At the same time, when they are fixed, the rubber ring 14 is in a deformed state at this time. Thus, the rubber ring 14 has a tendency to reset, making the second limit block 11 closely attached to the outer surface of the movable board 7, and fixing the position of the second limit block 11 through friction; after the first sound insulation board 2 and the second sound insulation board 3 are joined together, the screw rod 4 is rotated at this time, driving the pressing plate 5 to move until the pressing plate 5 closely adheres to the outer side of the transformer body 1. In this way, the positions of the first sound insulation board 2 and the second sound insulation board 3 are fixed through the friction between the pressing plate 5 and the transformer body 1.
