Description

Technical Field

[0001] The utility model relates to the technical field of excitation generators, in particular to a vibration-proof and noise-reducing structure of an excitation generator. Background Art

[0002] An excitation generator is a device that converts mechanical energy into electrical energy using the principle of electromagnetic induction. During the operation of an excitation generator, vibration and noise are common and unavoidable problems. The vibration and noise reduction structures of excitation generators in related technologies are mostly simple springs or rubber pads, which cannot effectively absorb and alleviate high-frequency vibrations, resulting in large vibrations during generator operation. Furthermore, most sound insulation measures only involve installing sound insulation panels on the outside of the generator, which cannot effectively isolate and absorb the noise generated inside. The noise is transmitted through vibration and still affects the surrounding environment. Therefore, it is necessary to improve the vibration and noise reduction structures of current excitation generators to solve the above problems.

[0003] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content

The noise is transmitted through vibration and still affects the surrounding environment.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A vibration-proof and noise-reduction structure for an excitation generator comprises a generator base, a soundproof cover and an excitation generator body, wherein four groups of spring hydraulic damping cylinders are symmetrically fixedly installed on the upper end of the generator base, a hydraulic oil pump is installed on one side of the spring hydraulic damping cylinder, and the four groups of spring hydraulic damping cylinders are respectively installed on both sides of the excitation generator body, a transmission wheel is installed on one side of the excitation generator body, a soundproof cover is installed on one side of the spring hydraulic damping cylinder, the interior of the soundproof cover is filled with sound insulation cotton, a soundproof cover is fixedly installed on the outer side of the generator base, and a transmission port is opened on one side of the soundproof cover.

[0007] As a preferred technical solution, soundproof door bodies are symmetrically installed on both sides of the soundproof cover, a lower hollow glass window is installed on one side of the soundproof door body, and an upper hollow glass window is installed on the upper end of the soundproof door body.

[0008] As a preferred technical solution, the soundproof door body is embedded in a slide bar inside the soundproof cover, a plurality of pulleys are installed on one side of the slide bar, and a handle is fixedly installed on one side of the soundproof door body.

[0009] As a preferred technical solution, a controller is fixedly mounted on the upper end of the generator base, and the controller is electrically connected to the hydraulic oil pump.

[0010] The beneficial effects of the utility model are:

[0011] Through this structure, the vibration generated by the excitation generator during operation is first absorbed by the spring hydraulic damping cylinder. The hydraulic oil pump further controls the magnitude of the damping force by adjusting the oil pressure, thereby effectively reducing the vibration transmitted to the generator base, reducing the impact of the generator on the surrounding structure during operation, reducing the risk of structural fatigue and damage caused by vibration, and improving the stability and service life of the generator. At the same time, it also provides a safer working environment for operators.

[0019] Reference Figure 1-2 A vibration-proof and noise-reduction structure for an excitation generator includes a generator base 1, a soundproof cover 2, and an excitation generator body 6. Four groups of spring hydraulic damping cylinders 8 are symmetrically fixedly installed on the upper end of the generator base 1. A hydraulic oil pump 801 is installed on one side of the spring hydraulic damping cylinder 8. The four groups of spring hydraulic damping cylinders 8 are respectively installed on both sides of the excitation generator body 6, and a transmission wheel 7 is installed on one side of the excitation generator body 6.

[0020] Through this design, the vibration generated by the excitation generator during operation is first absorbed by the spring hydraulic damping cylinder 8.

At the same time, it also provides a safer working environment for operators.

[0021] Among them, the interior of the spring hydraulic damping cylinder 8 is provided with a metal spring, a hydraulic cylinder, a damping hole, an end cover, a seal and an adjusting device. The spring is responsible for supporting the load and providing elastic restoring force, while the piston and the damping hole inside the hydraulic cylinder are used to control the flow of oil and generate damping force to consume vibration energy. The adjusting device can adjust the damping force as needed.

[0022] Among them, a sound insulation cover 2 is installed on one side of the spring hydraulic damping cylinder 8, the interior of the sound insulation cover 2 is filled with sound insulation cotton, the sound insulation cover 2 is fixedly installed on the outside of the generator base 1, a transmission port 10 is opened on one side of the sound insulation cover 2, and sound insulation door bodies 3 are symmetrically installed on both sides of the sound insulation cover 2.

[0023] Through this design, the soundproof cover 2 can effectively isolate and absorb the noise generated during the operation of the excitation generator. The sound insulation cotton filled inside further improves the sound insulation effect. The design of the transmission port 10 facilitates the connection and operation of the transmission wheel 7 without affecting the normal operation of the generator. The hollow glass windows 301 and 303 of the soundproof door body 3 not only have good sound insulation effect, but also can observe the internal operation of the generator, which is convenient for maintenance and monitoring.

[0024] In other embodiments, the soundproof door body 3 is embedded in the slide bar 4 inside the soundproof cover 2, a plurality of pulleys 5 are installed on one side of the slide bar 4, and a handle 302 is fixedly installed on one side of the soundproof door body 3.

[0025] Through this design, the design of the slide rod 4 and the pulley 5 enables the soundproof door body 3 to open and close smoothly, which is convenient for operation and maintenance. The installation of the handle 302 improves the convenience of using the soundproof door body 3. The operator can easily open and close the soundproof door, conduct equipment inspection and maintenance, and ensure the normal operation of the equipment.

[0026] In other embodiments, a controller 9 is fixedly mounted on the upper end of the generator base 1 , and the controller 9 is electrically connected to the hydraulic oil pump 801 .

[0027] In this embodiment, the vibration generated by the excitation generator during operation is first absorbed by the spring hydraulic damping cylinder 8, and the hydraulic oil pump 801 further controls the magnitude of the damping force by adjusting the oil pressure, thereby effectively reducing the vibration transmitted to the generator base 1, reducing the impact of the generator on the surrounding structure during operation, reducing the risk of structural fatigue and damage caused by vibration, and improving the stability and service life of the generator. At the same time, it also provides a safer working environment for operators.

[0028] In addition, the soundproof cover 2 can effectively isolate and absorb the noise generated during the operation of the excitation generator. The soundproof cotton filled inside further improves the sound insulation effect. The hollow glass windows 301 and 303 of the soundproof door body 3 not only have good sound insulation effect, but also can observe the internal operation of the generator, which is convenient for maintenance and monitoring.
