Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a transformer with a noise reduction structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization. Transformers are basic equipment for power transmission and distribution and are widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] Existing transformers are usually installed on a base when in use. As the power consumption in the area increases, the transformer will indirectly increase its power. Each time the power is increased, the transformer will vibrate, which is directly transmitted to the base through the bottom bracket, causing resonance and transmitting a lot of noise, affecting the surrounding environment and also causing damage to the transformer itself. Therefore, a transformer with a noise reduction structure is now designed to solve such defects. Summary of the Invention

[0012] Preferably, operation openings are provided on the surface and rear of the noise reduction frame, and a sealing door panel is installed inside the operation opening.

[0013] Beneficial effects The present invention provides a transformer with a noise reduction structure. Compared with existing technologies, it has the following advantages: (1) The transformer with noise reduction structure is provided with a noise reduction frame installed on the outside of the transformer body, and a shock-absorbing pad and a shock-absorbing cone are provided inside the noise reduction frame. The arrangement of these structures can use the threaded column to drive the upward force of the T-shaped support plate to make the shock-absorbing cone always fit with the bottom of the transformer body, so that the vibration caused by the power increase during the operation of the transformer body will not be directly transmitted to the base.

The arrangement of these structures can use the inclined support groove to squeeze the blocking plate when the T-shaped support plate pushes the annular support frame to rise, thereby pushing the buffer seat to move and adhere to the surface of the transformer body, so that the transformer body can use the buffer seat to limit the shaking amplitude when vibrating. At the same time, the flexibility of the buffer seat can effectively buffer, reducing the loss of the transformer body and providing protection for the equipment.

[0015] (3) The transformer with a noise reduction structure is used by installing a first guide frame and a second guide frame on the top of the noise reduction frame, and matching the docking slot and the rectangular plug. The arrangement of these structures can utilize the raised annular frame to install the first guide frame and the second guide frame with the rectangular plug. Then, the first guide frame and the second guide frame fit with the transformer body to guide rainwater on rainy days, thereby preventing a large amount of rainwater from entering the interior of the noise reduction frame, thereby effectively improving the overall practicality and functionality of the equipment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the 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.

[0019] See also Figure 1-8 The present invention provides a technical solution: a transformer with a noise reduction structure, including a noise reduction buffer mechanism 1, the noise reduction buffer mechanism 1 includes a noise reduction frame 101, base plates 102 are fixedly installed on both sides of the bottom of the inner cavity of the noise reduction frame 101, and a shock-absorbing pad 104 is installed on the top of the base plate 102. The shock-absorbing pad 104 is made of rubber. A transformer mechanism 2 is installed inside the noise reduction frame 101, and the transformer mechanism 2 includes a transformer body 201.

[0020] Furthermore, the front and rear sides of the top of the base plate 102 are fixedly connected to a threaded bolt 103 through a fixing block. The top of the threaded bolt 103 sequentially passes through the shock-absorbing pad 104 and the locking groove 203 and extends to the upper part of the positioning frame 202. The surface of the threaded bolt 103 is threadedly connected to a threaded cap 105, and the threaded cap 105 is located at the upper part of the positioning frame 202. The bottom of the inner cavity of the noise reduction frame 101 is rotatably connected to a threaded column 106 through a bearing member. The lower part of the surface of the threaded column 106 is fixedly connected to a ring handle 124. The surface of the threaded column 106 is threadedly connected to a threaded sleeve 107. The surface of the threaded sleeve 107 is rotatably installed with a T-shaped support plate 108, and the T-shaped support plate 108 is located at the bottom of the transformer body 201.

[0021] Furthermore, circular guide grooves 110 are provided at the front and rear of both sides of the top of the T-shaped support plate 108. A vertical guide rod 111 is slidably installed on the inner side of the circular guide groove 110. The bottom end of the vertical guide rod 111 is fixedly connected to the bottom of the inner cavity of the noise reduction frame 101 through a fixed block. Shock-absorbing cones 117 are fixedly installed on both sides of the top of the T-shaped support plate 108 through a fixed plate. The shock-absorbing cones 117 are made of rubber, and there are several shock-absorbing cones 117. The shock-absorbing cones 117 are in contact with the bottom of the transformer body 201. The top of the T-shaped support plate 108 is fixedly installed with an annular frame 109 through a fixed plate, and the annular frame 109 is fixedly installed with the ring. The resistance frame 109 is located between the transformer body 201 and the inner side of the noise reduction frame 101. A concave groove 112 is provided on the surface of the annular resistance frame 109. Rectangular through grooves 113 are provided on the surface, rear part and both sides of the concave groove 112, and there are several rectangular through grooves 113. A buffer seat 114 is provided on the inner side of the rectangular through groove 113. The buffer seat 114 is made of rubber. A blocking plate 115 is fixedly installed on one side of the buffer seat 114 located on the inner side of the concave groove 112. Inclined resistance grooves 116 used in conjunction with the blocking plate 115 are provided on both sides, front and rear parts of the inner cavity of the noise reduction frame 101.

[0022] Before use, first remove the two sealing door panels 123 from the inner side of the operating port 122, then place the two shock-absorbing pads 104 on the top of the two base plates 102 from the operating port 122, and pass the threaded bolts 103 through the shock-absorbing pads 104, then use the lifting equipment to lift the transformer body 201 to the inner side of the noise reduction frame 101, so that the positioning frame 202 falls on the top of the shock-absorbing pads 104, and at the same time, the threaded bolts 103 pass through the locking grooves 203, and then use tools to screw the threaded caps 105 and the threaded bolts 103 until the positioning frame 202 is fixed on the top of the shock-absorbing pads 104, and then manually rotate the annular handle 124 to drive the threaded column 106 to rotate. At this time, the T-shaped support plate 108 is driven by the threaded action of the threaded sleeve 107, and the circular guide grooves 110 and the vertical guide rods 111 are used to limit the T-shaped support plate 108. As the entire annular retaining frame 109 rises, the inclined retaining groove 116 on the inner wall of the noise reduction frame 101 will squeeze the blocking plate 115 when the annular retaining frame 109 rises, thereby pushing the blocking plate 115 closer to the transformer body 201. After the T-shaped support plate 108 is completely raised to the top, the annular retaining frame 109 is located between the noise reduction frame 101 and the transformer body 201. At the same time, several blocking plates 115 are squeezed and fitted onto the surface of the transformer body 201 by the inclined retaining groove 116, and several shock-absorbing cones 117 contact the bottom of the transformer body 201 and push it up, so that the positioning frame 202 and the shock-absorbing pad 104 generate reverse pulling force, and then the second guide frame 119 and the second guide frame 119 are respectively installed on both sides and the front and rear of the transformer body 201, and the docking slot 120 is inserted into the inner side of the rectangular plug 121.

[0023] Among them, the front and rear sides of the top of the noise reduction frame 101 are both provided with a first guide frame 118, and the second guide frame 119 is provided on both sides of the top of the noise reduction frame 101 and between the two first guide frames 118. One side of the first guide frame 118 and the second guide frame 119 is provided with a rubber layer for adhesion, and one side of the first guide frame 118 and the second guide frame 119 are both in contact with the surface of the transformer body 201. The bottom of the first guide frame 118 and the second guide frame 119 is provided with a docking slot 120, and there are several docking slots 120. The top of the annular frame 109 is fixedly connected with a rectangular plug block 121 used in conjunction with the docking slot 120. The surface and rear of the noise reduction frame 101 are provided with an operation port 122, and a sealing door panel 123 is installed on the inner side of the operation port 122.

[0024] During daily use, the shock-absorbing pad 104 isolates the positioning frame 202 from the base plate 102, and the shock-absorbing cone 117 fits the bottom of the transformer body 201. As a result, the vibration generated when the transformer body 201 is driven will not be directly transmitted to the noise reduction frame 101 through the transmission threaded bolt 103, thereby reducing the noise generated during resonance. At the same time, the provision of several buffer seats 114 can prevent the transformer body 201 from directly contacting the inner wall of the noise reduction frame 101 when vibrating, and can utilize the flexibility of the buffer seats 114 for buffering and noise reduction, thereby avoiding damage to the exterior of the transformer body 201 and reducing the impact sound. The provision of the first guide frame 118 and the second guide frame 119 can guide rainwater outward on rainy days, thereby preventing a large amount of rainwater from directly entering the interior of the noise reduction frame 101.
