Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer with a noise reduction structure. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions include voltage transformation, current transformation, impedance transformation, 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 during use. As the electricity consumption in the area increases, the transformer will indirectly increase its power. Each time the power is increased, the transformer will vibrate, which will be transmitted directly to the base through the support at the bottom, resulting in resonance and transmitting a lot of noise, affecting the surrounding environment and damaging the transformer itself. Therefore, a transformer with a noise reduction structure is now designed to address this type of defect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a transformer with a noise reduction structure, which solves the problem of existing transformers easily vibrating and generating noise.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transformer with a noise reduction structure, comprising a noise reduction buffer mechanism, wherein the noise reduction buffer mechanism comprises a noise reduction frame, and base plates are fixedly installed on both sides of the bottom of the noise reduction frame, and a shock-absorbing pad is installed on the top of the base plate. A transformer mechanism is installed inside the noise reduction frame, wherein the transformer mechanism comprises a transformer body, and positioning frames are fixedly installed on both sides of the bottom of the transformer body via fixing plates, and the positioning frames are located on the top of the shock-absorbing pad. Locking grooves are provided on the front and rear sides of the top of the base plate.

[0006] Preferably, the front and rear sides of the top of the base plate are fixedly connected with threaded bolts by fixing blocks. The top of the threaded bolt passes through the shock-absorbing pad and the locking groove in sequence and extends to the upper part of the positioning frame. The surface of the threaded bolt is threaded with a threaded cap, and the threaded cap is located on the upper part of the positioning frame.

[0007] Preferably, the bottom of the noise reduction frame cavity is rotatably connected to a threaded column via a bearing component, and an annular handle is fixedly connected to the lower part of the surface of the threaded column. A threaded sleeve is threadedly connected to the surface of the threaded column, and a T-shaped support plate is rotatably installed on the surface of the threaded sleeve, with the T-shaped support plate located at the bottom of the transformer body.

[0008] Preferably, the front and rear of both sides of the top of the T-shaped support plate are provided with circular guide grooves, and vertical guide rods are slidably installed on the inner side of the circular guide grooves. The bottom end of the vertical guide rods is fixedly connected to the bottom of the noise reduction frame cavity through a fixing block. Both sides of the top of the T-shaped support plate are fixedly installed with shock-absorbing cones through fixing plates, and several shock-absorbing cones are provided. The shock-absorbing cones are in contact with the bottom of the transformer body.

[0009] Preferably, the top of the T-shaped support plate is fixedly mounted with an annular abutment frame by a fixing plate, and the annular abutment frame is located between the transformer body and the inner side of the noise reduction frame. The surface of the annular abutment frame is provided with a concave groove. The surface, rear and sides of the concave groove are provided with rectangular through grooves, and there are several rectangular through grooves. A buffer seat is provided on the inner side of the rectangular through groove. A stop plate is fixedly mounted on the side of the buffer seat located inside the concave groove. The inner cavity of the noise reduction frame is provided with inclined abutment grooves on both sides, front and rear, which cooperate with the stop plate.

[0010] Preferably, a first flow guide frame is provided on the front and rear sides of the top of the noise reduction frame, and a second flow guide frame is provided on both sides of the top of the noise reduction frame and between the two first flow guide frames, and one side of the first flow guide frame and the second flow guide frame are in contact with the surface of the transformer body.

[0011] Preferably, the bottom of the first guide frame and the second guide frame are provided with docking slots, and there are several docking slots. The top of the annular abutment frame is fixedly connected with a rectangular insert block that cooperates with the docking slot.

[0012] Preferably, the noise reduction frame has an operation port on both its surface and rear, and a sealing door panel is installed on the inner side of the operation port.

[0013] Beneficial effects This 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 has a noise reduction frame installed on the outside of the transformer body, and a vibration damping pad and a vibration damping cone are set inside the noise reduction frame. The setting of these structures can use the threaded column to drive the T-shaped support plate to make the vibration damping cone always fit with the bottom of the transformer body. This prevents the vibration caused by the increased power of the transformer body during operation from being directly transmitted to the base. The vibration damping pad and the vibration damping cone are used to reduce the vibration sensation, effectively reducing the noise emitted by the transformer during use and making it more convenient to use.

[0014] (2) The transformer with noise reduction structure has an annular support frame installed on the top of the T-shaped support plate and a buffer seat installed on the inner side of the annular support frame. It is used in conjunction with the stop plate and the inclined groove. When the T-shaped support plate pushes the annular support frame up, the inclined groove squeezes the stop plate, thereby pushing the buffer seat to move and stick to the surface of the transformer body. This allows the transformer body to reduce the shaking amplitude when it vibrates by using the limit of the buffer seat. At the same time, the flexibility of the buffer seat can effectively buffer the vibration, reduce the loss of the transformer body, and protect the equipment.

[0015] (3) The transformer with 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 using docking slots and rectangular plugs. The structure can use the raised annular support frame to install the first guide frame and the second guide frame with the rectangular plugs. Then the first guide frame and the second guide frame are attached to the transformer body to guide rainwater in rainy weather, preventing a large amount of rainwater from entering the interior of the noise reduction frame, effectively improving the overall practicality and functionality of the equipment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0019] Please see 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 including a noise reduction frame 101, a base plate 102 fixedly installed on both sides of the bottom of the inner cavity of the noise reduction frame 101, a shock-absorbing pad 104 installed on the top of the base plate 102, the shock-absorbing pad 104 being made of rubber, a transformer mechanism 2 installed inside the noise reduction frame 101, the transformer mechanism 2 including a transformer body 201, a positioning frame 202 fixedly installed on both sides of the bottom of the transformer body 201 by a fixing plate, and the positioning frame 202 being located on the top of the shock-absorbing pad 104, and a locking groove 203 being provided on the front and rear sides of the top of the base plate 102.

[0020] Furthermore, threaded bolts 103 are fixedly connected to the front and rear sides of the top of the base plate 102 by fixing blocks. The top of the threaded bolts 103 passes through the shock-absorbing pad 104 and the locking groove 203 in sequence and extends to the upper part of the positioning frame 202. The surface of the threaded bolts 103 is threadedly connected to the threaded caps 105, and the threaded caps 105 are located on the upper part of the positioning frame 202. The bottom of the inner cavity of the noise reduction frame 101 is rotatably connected to the threaded post 106 by bearing components. The lower part of the surface of the threaded post 106 is fixedly connected to the ring handle 124. The surface of the threaded post 106 is threadedly connected to the threaded sleeve 107. The surface of the threaded sleeve 107 is rotatably mounted 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 on the front and rear parts of both sides of the top of the T-shaped support plate 108. Vertical guide rods 111 are slidably installed on the inner side of the circular guide grooves 110. The bottom end of the vertical guide rods 111 is fixedly connected to the bottom of the inner cavity of the noise reduction frame 101 through a fixing block. Vibration damping cones 117 are fixedly installed on both sides of the top of the T-shaped support plate 108 through fixing plates. The vibration damping cones 117 are made of rubber, and several vibration damping cones 117 are provided. The vibration damping cones 117 are in contact with the bottom of the transformer body 201. An annular abutment frame 109 is fixedly installed on the top of the T-shaped support plate 108 through a fixing plate. The abutment frame 109 is located between the transformer body 201 and the inner side of the noise reduction frame 101. The surface of the annular abutment frame 109 is provided with a concave groove 112. The surface, rear and sides of the concave groove 112 are provided with rectangular through grooves 113, and there are several rectangular through grooves 113. The inner side of the rectangular through groove 113 is provided with a buffer seat 114. The buffer seat 114 is made of rubber. A stop plate 115 is fixedly installed on the side of the buffer seat 114 located inside the concave groove 112. The inner sides, front and rear of the noise reduction frame 101 are provided with inclined abutment grooves 116 that cooperate with the stop plate 115.

[0022] Before use, remove the two sealing door panels 123 from the inside of the operating port 122. Then, place the two shock-absorbing pads 104 on top of the two base plates 102 from the operating port 122, and let the threaded bolt 103 pass through the shock-absorbing pads 104. Then, use hoisting equipment to hoist the transformer body 201 to the inside of the noise reduction frame 101, so that the positioning frame 202 falls on top of the shock-absorbing pads 104, and at the same time, the threaded bolt 103 passes through the locking groove 203. Then, use tools to tighten the threaded cap 105 and the threaded bolt 103 until the positioning frame 202 is fixed on top of the shock-absorbing pads 104. Then, manually rotate the ring handle 124 to drive the threaded column 106 to rotate. At this time, the T-shaped support plate 108 is driven by the thread of the threaded sleeve 107, and the T-shaped support plate 108 is driven by the limiting of the circular guide groove 110 and the vertical guide rod 111. As the entire annular support frame 109 rises, the inclined groove 116 on the inner wall of the noise reduction frame 101 will squeeze the stop plate 115, thereby pushing the stop plate 115 closer to the transformer body 201. After the T-shaped support plate 108 has completely risen to the top, the annular support frame 109 is located between the noise reduction frame 101 and the transformer body 201. At the same time, several stop plates 115 are squeezed and adhered to the surface of the transformer body 201 by the inclined groove 116, and several shock-absorbing cones 117 contact the bottom of the transformer body 201 and push it upward, so that the positioning frame 202 and the shock-absorbing pad 104 generate opposite pulling forces. Then, the second flow guide frame 119 is installed on both sides and the front and rear of the transformer body 201 respectively, so that the docking slot 120 is inserted into the inner side of the rectangular plug 121.

[0023] The noise reduction frame 101 has a first flow guide frame 118 on the front and rear sides of its top. A second flow guide frame 119 is provided on both sides of the top of the noise reduction frame 101 and between the two first flow guide frames 118. A rubber layer is provided on one side of both the first flow guide frame 118 and the second flow guide frame 119, and one side of both the first flow guide frame 118 and the second flow guide frame 119 is in contact with the surface of the transformer body 201. A docking slot 120 is provided at the bottom of the first flow guide frame 118 and the second flow guide frame 119, and several docking slots 120 are provided. A rectangular insert 121 that cooperates with the docking slot 120 is fixedly connected to the top of the annular abutment frame 109. An operation port 122 is provided on the surface and rear of the noise reduction frame 101, and a sealing door plate 123 is installed on the inner side of the operation port 122.

[0024] In daily use, because the shock-absorbing pad 104 isolates the positioning frame 202 from the base plate 102, and the shock-absorbing cone 117 is attached to the bottom of the transformer body 201, 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 setting 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. The flexibility of the buffer seats 114 can be used for buffering and noise reduction, which not only avoids damage to the exterior of the transformer body 201, but also reduces the impact sound. The setting of the first guide frame 118 and the second guide frame 119 can guide rainwater outward during rainy days, preventing a large amount of rainwater from directly entering the interior of the noise reduction frame 101.
