Description

Technical Field

[0001] The invention belongs to the technical field of transformers, and in particular relates to a transformer with a sound insulation base. Background Art

[0002] Transformer noise has always troubled technicians in this field, especially transformers installed in basements. Because they are close to residents on the first floor, and the vibration of the transformer can be transmitted to the steel bars in the cement through the rigid connection with the ground, thus generating low-frequency noise. To avoid the occurrence of the above problems, technicians in this field usually adopt the method of building a soundproof room, installing sound insulation cotton on the walls of the transformer room, and installing silencers on the vents to absorb and consume the noise. However, although the above method reduces the vibration noise of the transformer itself, it still does not solve the problem of low-frequency noise generated by the transmission of the connecting parts to the steel bars in the cement. Summary of the Invention

[0003] To address the aforementioned technical issues, the present invention provides a transformer with a soundproof base. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is provided below. This summary is not intended to be a comprehensive review, identify key or important components, or delineate the scope of protection for these embodiments. Its sole purpose is to present some concepts in a simplified form, serving as a prelude to the detailed description that follows.

[0004] The present invention adopts the following technical solutions:

[0005] In some optional embodiments, a transformer with a sound insulation base includes a transformer body and a sound insulation base; the transformer body is fixedly connected to the sound insulation base;

[0006] The sound insulation base includes a first partition and a second partition; the first partition and the second partition are both provided with teeth that cooperate with each other, and rubber pads are filled between the teeth of the first partition and the teeth of the second partition; the fixed end of the first partition and the fixed end of the second partition are respectively fixed to the ground to be fixed by L-shaped center bolts; the first partition and the second partition can respectively generate horizontal rotation angles with their own L-shaped center bolts as the center of the circle.

[0007] Furthermore, it also includes a rubber gasket; a through groove is opened on the lower surface of the sound insulation base, and the rubber gasket is installed in the through groove.

[0008] Furthermore, it also includes a waterproof cloth; the waterproof cloth is arranged on the upper surface of the partition base.

[0009] Furthermore, it also includes a sound insulation cotton layer, which is attached to the upper surface and side surface of the sound insulation base.

[0010] Furthermore, the transformer body and the sound insulation base are fixedly connected by bolts.

[0011] Furthermore, the teeth of the first partition plate and the second partition plate are round teeth.

[0012] Furthermore, it also includes auxiliary positioning bolts, which are evenly arranged on the fixed ends of the first partition and the second partition, and fixedly install the first partition and the second partition on the fixed ground.

[0013] The present invention provides the following beneficial effects: By installing the sound insulation base, the vibration of the transformer body is transmitted to the sound insulation base. The vibration of the sound insulation base is buffered by the rubber pad located between the first and second partitions, thereby reducing the vibration energy transmitted to the ground and further reducing the vibration transmitted to the steel bars in the concrete, thereby reducing low-frequency noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the present invention;

[0015] Figure 2 This is a schematic structural diagram of the sound insulation base of the present invention;

[0016] Figure 3 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0017] The following description and accompanying drawings fully illustrate specific embodiments of the present invention to enable those skilled in the art to practice them. Other embodiments may include structural, logical, electrical, process and other changes. The examples represent only possible variations. Unless clearly required, separate components and functions are optional, and the order of operation may vary. Parts and features of some embodiments may be included in or replace parts and features of other embodiments.

[0018] In some illustrative embodiments, Figure 1-2 As shown, a transformer with a soundproof base includes a transformer body 1 and a soundproof base. The soundproof base is preferably made of steel and coated with an anti-corrosion and anti-rust paint to prevent corrosion in the cold and humid environment of the basement, which could lead to performance degradation. Connecting threaded holes 2 are provided at both ends of the soundproof base. The two ends of the bottom of the transformer body 1 are fixed to the soundproof base via fixing bolts and threaded holes 2. When fixing the transformer body 1 to the soundproof base, the soundproof base and transformer body 1 are placed on the ground to be fixed.

[0019] The sound insulation base includes a first partition plate 3 and a second partition plate 4. The tooth ends of the first partition plate 3 and the second partition plate 4 are provided with mutually matching tooth portions. The tooth portion 301 of the first partition plate and the tooth portion 401 of the second partition plate have a gap, and a rubber pad 5 is installed in the gap. The rubber pad 5 fills the gap between the tooth portion 301 of the first partition plate and the tooth portion 401 of the second partition plate, and fits tightly with the tooth portion 301 of the first partition plate and the tooth portion 401 of the second partition plate respectively. The fixed end of the first partition plate 3 and the fixed end of the second partition plate 4 are respectively fixed to the ground to be fixed by an L-shaped center bolt 6. Auxiliary positioning bolts 7 are evenly arranged on the fixed ends of the first partition plate 3 and the second partition plate 4. The partition base is thereby fixed to the ground to be fixed by the L-shaped center bolt 6 and the auxiliary positioning bolt 7.

[0020] During use, the transformer body 1 inevitably vibrates due to technical reasons. Since the transformer body 1 is rigidly connected to the soundproof base, the vibration is transmitted to the base. The soundproof base is divided into a first baffle 3 and a second baffle 4. When the first baffle 3 and the second baffle 4 vibrate, they can produce a horizontal angle of rotation about their own L-shaped center bolt. This horizontal angle is very small, only the tiny angle generated during the vibration of the steel structure. Through the rubber pad, the first baffle 3 and the second baffle 4 transfer the received vibration energy to the rubber pad 5 for dissipation, thereby reducing the amount of vibration energy transferred to the steel bars in the cement, effectively reducing the generation of low-frequency noise.

[0021] During the experiment, the teeth of the first and second partitions 3 and 4 could be sharp teeth. However, the sharp teeth constantly vibrate during use, generating shear force on the rubber pad, which shortens the life of the rubber pad. Therefore, the teeth of the first and second partitions 3 and 4 are preferably round teeth.

[0022] In an optional embodiment, a rubber gasket 8 is further included. In order to prevent the tooth ends of the first partition plate 3 and the second partition plate 4 from being unfixed and colliding with the ground after vibration to form low-frequency noise, a through groove is opened on the lower surface of the sound insulation base, and the rubber gasket 8 is installed in the through groove.

[0023] In an optional embodiment, as Figure 3 As shown, it also includes a waterproof cloth 9; the waterproof cloth 9 is arranged on the upper surface of the partition base.

[0024] In an optional embodiment, as Figure 3 As shown, it also includes a sound insulation cotton layer 10, which is attached to the upper surface and side surface of the sound insulation base to minimize the transmission of the vibration sound of the sound insulation base itself.

[0025] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be considered as equivalent replacement methods and should be included in the scope of protection of the present invention.
