[0045] Embodiment 2

[0046] In another preferred embodiment, on the basis of the above Embodiment 1, as Figure 1As shown in the figure, a shock absorption and noise reduction device for a transformer includes a base 1. At the center of the upper surface of the base 1, there is a placement groove 2, and buffer grooves 3 are provided on the inner walls on both the left and right sides of the placement groove 2.

[0047] As Figure 2 shown, an installation plate 4 is provided in the placement groove 2, and both sides of the installation plate 4 extend into the buffer grooves 3. A plurality of telescopic rods 5 are fixedly installed on the inner wall of the buffer groove 3. One end of the telescopic rod 5 is fixedly installed with a trapezoidal inclined plate 6, and the trapezoidal inclined plate 6 abuts against the side surface of the installation plate 4. A spring 7 is sleeved on the outer surface of the telescopic rod 5. One end of the spring 7 is fixedly connected to the inner wall of the buffer groove 3, and the other end is fixedly connected to the side surface of the trapezoidal inclined plate 6. A transformer 8 is fixedly installed on the upper surface of the installation plate 4. Installation frames 9 are fixedly installed on both sides of the transformer 8. Bolts are provided on the installation frames 9, and the installation frames 9 are fixedly connected to the installation plate 4 through the bolts. First friction surfaces are provided on the surfaces between the installation plate 4 and the placement groove 2, and a second friction surface is provided between the upper surface of the trapezoidal inclined plate 6 and the inner wall of the buffer groove 3. When the vibration generated during the operation of the transformer 8 drives the installation plate 4 to slide in the buffer groove 3, both sides of the installation plate 4 will squeeze the trapezoidal inclined plate 6, compressing the spring 7. At the same time, the friction surface on the bottom surface of the installation plate 4 will rub against the friction surface of the placement groove 2, converting the vibration kinetic energy of the installation plate 4 into heat energy, thereby effectively damping the installation plate 4. In addition, a buffer pad is provided between the transformer 8 and the installation plate 4 to further reduce the impact of vibration on the transformer 8.

[0048] As Figure 3 shown, a protective shell 10 is fixedly installed on the upper surface of the base 1, and the protective shell 10 is arranged outside the transformer 8. A plurality of damping rods 11 are provided on the inner wall of the protective shell 10. Damping liquid is provided inside the damping rods 11. One end of the damping rod 11 is fixedly installed with a support plate 12, and the support plate 12 abuts against the surface of the transformer 8. When the transformer 8 is operating, its vibration will drive the support plate 12 to compress the damping rods 11 left and right, and the damping liquid flows inside the damping rods 11 to generate resistance, further absorbing and dispersing the vibration energy to achieve the effect of shock absorption. A sound insulation board 13 is also fixedly installed on the inner wall of the protective shell 10, and the sound insulation board 13 can effectively absorb the noise generated during the operation of the transformer 8 and reduce the impact of the noise on the surrounding environment. At the same time, heat dissipation fins are fixedly installed on the surface of the transformer 8, and a plurality of dust-proof nets are fixedly installed on the surface of the protective shell 10. The positions of the dust-proof nets correspond to those of the heat dissipation fins, so that both the heat dissipation effect of the transformer 8 can be ensured and dust can be prevented from entering the inside of the protective shell 10.

[0050] It should be noted that, in the specific embodiment, for the selection of the spring 7, a material with high elasticity and high durability can be considered to ensure that a good shock absorption effect can be maintained during long-term use. At the same time, the telescopic length of the telescopic rod 5 and the damping coefficient of the damping rod 11 can be adjusted according to the specific model of the transformer and the working environment to achieve the best shock absorption effect.

[0051] In addition, the material of the protective shell 10 can be selected from metal materials or plastic materials with certain strength and toughness, which can not only ensure the protection effect of the transformer, but also reduce the overall weight of the device. The material of the sound insulation board 13 can be selected from materials with good sound insulation performance, such as foamed aluminum, sound insulation felt, etc., to improve the noise reduction effect of the device.

[0052] When designing a dustproof net, in addition to considering the dustproof effect, the heat dissipation effect must also be considered to avoid poor heat dissipation caused by the dustproof net being too dense. Therefore, in the design of the dustproof net, the needs of dustproof and heat dissipation need to be comprehensively considered to achieve the best use effect.

[0053] In the preferred scheme, inclined surfaces are provided on both sides of the mounting plate 4, and the two sides of the mounting plate 4 match the side surfaces of the trapezoidal inclined plate 9, that is, the shape, angle or slope of the inclined surfaces on both sides of the mounting plate 4 are consistent with the side surfaces of the trapezoidal inclined plate 9 or can be perfectly docked and tightly connected together; the above setting makes the connection between the mounting plate 4 and the trapezoidal inclined plate 9 more stable, and at the same time can reduce the gap between the mounting plate 4 and the trapezoidal inclined plate 9, avoid shaking or falling off during use, and improve the overall stability and safety.

[0054] In the preferred scheme, a first friction surface is provided on the surface between the mounting plate 4 and the placement groove 2, and a second friction surface is provided between the upper surface of the trapezoidal inclined plate 9 and the inner wall of the buffer groove 3; the above arrangement, through the arrangement of the first friction surface and the second friction surface, can increase the friction force between the mounting plate 4 and the placement groove 2 and between the trapezoidal inclined plate 9 and the buffer groove 3, so that the mounting plate 4 and the trapezoidal inclined plate 9 are not easy to slip when subjected to force.

[0055] In the preferred solution, mounting frames 6 are fixedly installed on both sides of the transformer 5, bolts are provided on the mounting frames 6, and the mounting frames 6 are fixedly connected to the mounting plate 4 through the bolts; the above arrangement, through the cooperation of the mounting frames 6 and the bolts, facilitates the installation and disassembly of the transformer 5, and the maintenance and replacement of the transformer 5 in the later stage, thereby improving the use efficiency of the transformer 5 and reducing the cost of later maintenance.

[0056] In a preferred embodiment, a buffer pad 10 is provided between the transformer 5 and the mounting plate 4. By providing the buffer pad 10, the friction and vibration between the transformer 5 and the mounting plate 4 can be reduced, thereby preventing the transformer 5 from being damaged or shifted due to vibration during operation, thereby improving its service life and stability.

[0057] In a preferred embodiment, a heat sink is fixedly installed on the surface of the transformer 5, and a plurality of dust-proof nets 15 are fixedly installed on the surface of the protective case 11. The positions of the dust-proof nets 15 correspond to those of the heat sink. With the above settings, the dust-proof nets 15 can prevent dust from entering the heat sink and avoid affecting the heat dissipation effect. The heat sink can increase the heat dissipation area and improve the heat dissipation efficiency, thus ensuring the normal operation of the transformer 5.

[0058] In a preferred embodiment, damping liquid is provided inside the damping rod 12. With the above settings, when an external force acts on the damping rod 12, the damping liquid generates frictional resistance inside the damping rod 12, thereby consuming the energy of the external force and achieving the purpose of slowing down the movement speed of the damping rod 12, thus improving the damping effect.

[0059] In a preferred embodiment, a fixing frame 16 is fixedly installed at the bottom of the base 1. With the above settings, by fixedly installing the fixing frame 16 at the bottom of the base 1, it is convenient to fix the entire device, avoid the device from tipping over, increase the stability of the device, and thus improve the practicality of the device.
