Description

Technical Field

[0001] This utility model relates to the field of noise control technology, and in particular to a transformer noise isolation device. Background Technology

[0002] With rapid urbanization and increasing public awareness of environmental protection, the requirements for noise control of power facilities are becoming increasingly stringent. Especially when substations are built near residential areas, effective noise control measures must be implemented to ensure compliance with local environmental regulations and residents' quality of life standards. Furthermore, in industrial sites, transformer noise must also be addressed to protect employee health. Therefore, the research and application of transformer noise isolation devices has become an important issue for the power industry.

[0003] Currently, in order to address the challenge of transformer noise, the industry has adopted a variety of noise control methods, such as optimizing the coil winding method to reduce electromagnetic noise or selecting low-noise fans to reduce mechanical noise. These measures have indeed effectively reduced noise levels to some extent. However, they are usually accompanied by high cost investment, and there are certain difficulties and technical challenges in implementing retrofits for existing equipment. Therefore, we propose a transformer noise isolation device to solve the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a transformer noise isolation device.

[0005] The technical implementation of this utility model is as follows: A transformer noise isolation device includes a housing, which serves as the mounting carrier for the noise isolation device. The housing is a square frame adapted to a transformer, with an opening on the front side for inserting the transformer. The housing also includes a storage cavity for placing the transformer. Furthermore, it includes a hinge, a soundproof door panel, a locking assembly, a handle, a soundproof layer, a rubber sheet, and fastening components. A soundproof door panel is hinged to one side of the front opening of the housing, and an inner edge at the edge of the front opening of the housing is provided to accommodate the soundproof door panel. The housing has a recessed groove, and a latch assembly for locking the soundproof door panel is provided on the housing. A handle is fixedly installed on the side of the door panel away from the hinge. The door panel can rotate to fit against the front side of the housing and is stably locked in the recessed groove of the front opening of the housing by the latch assembly. A sound insulation layer is provided in the inner wall interlayer of the housing. The sound insulation layer covers the interlayer of the entire side and back of the housing. A rubber plate is provided at the edge of the front opening of the housing. A fastening member is provided on the inner wall of the housing near the opening to press the rubber plate.

[0006] Optionally, the fastening component includes a support plate, a guide rod, a sliding plate, and a spring. Multiple support plates are circumferentially fixed on the inner wall of the housing near the front opening. Guide rods are slidably mounted on each support plate. The sliding plate is slidably mounted on the support plate via the guide rods. The sliding plate is a rectangular frame plate adapted to the size of the front opening of the housing. A spring is provided at the guide rod between the sliding plate and the support plate. A rubber plate is installed on the side of the sliding plate facing the front opening of the housing. When the soundproof door panel is closed onto the housing, it will press the rubber plate on the sliding plate. Under the action of the spring, the rubber plate on the sliding plate can be tightly attached to the soundproof door panel.

[0007] Optionally, the soundproof door panel and soundproof layer have characteristics such as high density, multi-layer structure and good elasticity. Specifically, the soundproof door panel and soundproof layer are made of multiple layers of sound-absorbing materials such as mineral wool, glass fiber or foam plastic.

[0008] Optionally, connecting plates are fixed to the lower two outer walls of the housing, a base is provided below the housing, a support frame is slidably sleeved on the base, a vibration damping component is provided between the support frame and the base, and the connecting plates are assembled onto the support frame by mounting bolts. The support frame and the base are used to stably support the housing, and together with the vibration damping component, they are used to reduce vibration of the housing of the soundproof transformer.

[0009] Optionally, the vibration damping component is specifically a damper, and multiple dampers are provided and evenly distributed between the support frame and the base. The damper is used to absorb the vibration between the support frame and the base.

[0010] Optionally, a second spring is provided around each of the dampers between the support frame and the base. The second spring is used to store energy when compressed or stretched, thereby optimizing the smooth movement of the damper.

[0011] Optionally, a second rubber plate is provided between the connecting surface of the connecting plate of the housing and the supporting frame, and the second rubber plate is used to further buffer the vibration transmitted on the housing.

[0012] This utility model has the following advantages:

[0013] 1.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] A transformer noise isolation device, such as Figures 1-4As shown, the device includes a housing 1, which serves as the mounting carrier for the soundproofing device. The housing 1 is a square frame adapted to a transformer, with an opening on the front for inserting the transformer. The housing 1 also includes a storage cavity for the transformer. Other components include a hinge 2, a soundproof door panel 3, a locking assembly 31, a handle 4, a soundproof layer 5, a rubber sheet 10, and fastening components. The soundproof door panel 3 is hinged to one side of the front opening of the housing 1 via the hinge 2. A recessed groove for the soundproof door panel 3 is provided at the edge of the front opening of the housing 1. The housing 1 has a locking assembly 31 for locking the soundproof door panel 3. A handle 4 is fixedly installed on the side of the door panel away from the hinge 2, allowing the door panel to rotate and fit snugly. The sound insulation layer 5 is provided in the inner groove of the front opening of the housing 1 and is stably locked by the locking assembly 31. The sound insulation layer 5 covers the entire side and back of the housing 1. A rubber plate 10 is provided at the edge of the front opening of the housing 1. A fastening member is provided on the inner wall of the housing 1 near the opening to press the rubber plate 10. When the sound insulation door panel 3 is closed on the housing 1, the fastening member can push the rubber plate 10 and stick it tightly to the sound insulation door panel 3, preventing the noise generated by the transformer from leaking out from the gap between the sound insulation door panel 3 and the housing 1, so as to achieve the effect of the housing 1 isolating the transformer noise.

[0023] like Figure 2 and Figure 3 As shown, the fastening components include a support plate 6, a guide rod 7, a sliding plate 9, and a spring 8. Multiple support plates 6 are circumferentially fixed on the inner wall of the housing 1 near the front opening. Guide rods 7 are slidably mounted on each support plate 6. The sliding plate 9 is slidably mounted on the support plate 6 via the guide rods 7. The sliding plate 9 is a rectangular frame plate adapted to the size of the front opening of the housing 1. Springs 8 are provided at the guide rods 7 between the sliding plate 9 and the support plate 6. A rubber plate 10 is installed on the side of the sliding plate 9 facing the front opening of the housing 1. When the soundproof door panel 3 is closed onto the housing 1, it will press the rubber plate 10 on the sliding plate 9. Under the action of the spring 8, the rubber plate 10 on the sliding plate 9 can fit tightly against the soundproof door panel 3, improving the isolation and sealing performance of the housing 1.

[0024] like Figure 2 and Figure 3 As shown, the soundproof door panel 3 and the soundproof layer 5 have characteristics such as high density, multi-layer structure and good elasticity. Specifically, the soundproof door panel 3 and the soundproof layer 5 are made of multiple layers of sound-absorbing materials such as mineral wool, glass fiber or foam plastic.

[0025] like Figure 1As shown, connecting plates 11 are fixed to the lower two outer walls of the housing 1. A base 14 is provided below the housing 1. A support frame 13 is slidably sleeved on the base 14. A vibration damping component is provided between the support frame 13 and the base 14. The connecting plates 11 are used to assemble the entire housing 1 onto the support frame 13 by mounting bolts 111. The support frame 13 and the base 14 are used to stably support the housing 1. Together with the vibration damping component, they are used to dampen the vibration of the housing 1 of the soundproof transformer, thereby further reducing the noise caused by vibration.

[0026] like Figure 1 and Figure 4 As shown, the vibration damping component is specifically a damper 15. Multiple dampers 15 are provided and evenly distributed between the support frame 13 and the base 14. The dampers 15 are used to absorb the vibration between the support frame 13 and the base 14, thereby stabilizing the system and reducing vibration and noise. Each damper 15 between the support frame 13 and the base 14 is provided with a second spring 16 around its periphery. The second spring 16 is used to store energy when compressed or stretched, thereby optimizing the smooth movement of the damper 15.

[0027] like Figure 1 As shown, a rubber plate 12 is provided between the connecting plate 11 of the housing 1 and the connecting surface of the support frame 13. The rubber plate 12 is used to further buffer the vibration transmitted on the housing 1 and reduce the secondary noise caused by the vibration.

[0028] When installing the transformer, first open the soundproof door panel 3, place the transformer in the storage cavity inside the housing 1, and then close the soundproof door panel 3. When the soundproof door panel 3 is closed onto the housing 1, it will press against the rubber plate 10 on the sliding plate 9. Due to the presence of the spring 8, the rubber plate 10 can fit tightly against the door panel, thereby enhancing the sealing performance of the housing 1 and reducing noise transmission. Continue until the soundproof door panel 3 fits into the inner groove at the front opening of the housing 1, and use the locking assembly 31 to securely lock the soundproof door panel 3 onto the housing 1, ensuring a sealed environment. At this time, because the housing 1 has a sound insulation layer 5 inside, covering the entire side and back of the housing 1, the soundproof door panel 3 is securely locked onto the housing 1. This sound insulation layer 5 is composed of high-density, multi-layered sound-absorbing materials with good elasticity, such as mineral wool, glass fiber, or foam plastic, designed to absorb and attenuate the noise generated when the transformer is working. To further address the vibration problem that may occur when isolating the transformer inside the housing 1, multiple evenly distributed dampers 15 are provided between the base 14 and the support frame 13 as vibration damping components to absorb vibration energy. Each damper 15 is also surrounded by a spring 16, which can store energy when compressed or stretched, optimize the action of the damper 15, and ensure smooth movement. In addition, the rubber plate 12 between the connecting plate 11 of the housing 1 and the support frame 13 provides additional cushioning, further reducing the vibration transmitted by the housing 1.

[0029] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
