The vacuum component 6 evacuates the noise reduction housing 2 to a vacuum, which can reduce the air noise around the motor equipment and improve the operating efficiency and service life of the equipment. The vacuum environment effectively reduces the noise caused by air conduction, thereby reducing the noise level generated by the electromechanical equipment. By starting the vacuum pump 605, the vacuum pump 605 draws the air in the noise reduction housing 2 into the first pipe 602 through the exhaust hole 601, and the air enters the vacuum pump 605 through the valve 603.

By setting the noise reduction component 5, when the electromechanical equipment body 1 is running, the energy generated by the vibration will be absorbed and dispersed by the vibration reduction spring 504 and the repulsive force between the first magnet 502 and the second magnet 503, thereby reducing the impact of the vibration on the surrounding environment and structure, reducing the generation and propagation of noise, and improving the operating stability and reliability of the electromechanical equipment. The cooling component 4 is set to ensure the heat dissipation effect of the electromechanical equipment body 1 and increase the service life of the electromechanical equipment body 1. The coolant in the water tank 402 is cooled by the air cooler 401 and pumped into the heat exchange shell 406 by the water pump 404, and heat exchange operation is performed with the electromechanical equipment body 1 to achieve the purpose of heat dissipation.

[0028] Specifically, a damper 7 is installed inside the noise reduction housing 2 , and one end of the damper 7 is connected to the heat exchange housing 406 .

[0029] Through the above technical solution, the damper 7 arranged inside the noise reduction shell 2 cooperates with the noise reduction component 5 to reduce the impact of vibration on the surrounding environment and structure, and reduce the generation and propagation of noise.

[0033] Through the above technical solution, the heat exchange shell 406 is attached to the outer side of the electromechanical device body 1, and the U-shaped tube arranged inside facilitates the entry of the coolant, thereby taking away the heat of the electromechanical device body 1 during operation.

[0034] Specifically, there are multiple groups of buffer rods 505 , which are symmetrically distributed on the outer side of the heat exchange shell 406 , and the first magnet 502 and the second magnet 503 repel each other.

[0035] Through the above technical solution, the energy generated by vibration is absorbed and dispersed by utilizing the damping spring 504 and the repulsive force between the first magnet 502 and the second magnet 503 , and the multiple groups of buffer rods 505 perform all-round buffering on the electromechanical equipment body 1 .

[0036] Specifically, the buffer groove 506 penetrates the fixing rod 501 and extends to the outside thereof, and the buffer rod 505 is detachably connected to the heat exchange shell 406 .

[0037] Through the above technical solution, the buffer groove 506 absorbs and disperses the vibration energy generated by the electromechanical equipment body 1 during operation, thereby reducing the impact of the vibration on the surrounding environment and structure, and the buffer rod 505 is easy to disassemble and install.

[0038] Specifically, the first pipe 602 is connected to the noise reduction housing 2 through the air extraction hole 601 , the valve 603 is connected to the vacuum pump 605 through the second pipe 604 , and the vacuum pump 605 is detachably installed inside the installation bin 3 .

[0039] Through the above technical solution, the exhaust hole 601 is convenient for processing the air in the noise reduction shell 2. Opening the valve 603 facilitates the air to enter the vacuum pump 605 for processing. Closing the valve 603 maintains the vacuum inside the noise reduction shell 2 to reduce noise propagation. The vacuum pump 605 is a prior art and will not be described in detail here.

[0040] During use, when it is necessary to reduce the noise of the electromechanical device body 1 during operation, start the vacuum pump 605, the vacuum pump 605 draws the air in the noise reduction housing 2 into the first pipe 602 through the air extraction hole 601, open the valve 603, the air passes through the valve 603 and enters the second pipe 604, finally the noise reduction housing 2 is evacuated to a vacuum through the vacuum pump 605, the valve 603 is closed to maintain the vacuum inside the noise reduction housing 2, and the noise transmission is reduced.

The heat is pumped into the heat exchange shell 406 through the connecting pipe 405, and the heat exchange shell 406 performs heat exchange operation with the electromechanical equipment body 1 to achieve the purpose of heat dissipation. When it is necessary to reduce the vibration energy of the electromechanical equipment body 1, the buffer rod 505 is symmetrically installed on the outside of the heat exchange shell 406, and the shock-absorbing spring 504 sleeved on the outside of the buffer groove 506 absorbs and disperses the vibration energy. The second magnet 503 arranged at one end of the buffer rod 505 forms a repulsive force with the first magnet 502 installed in the fixed rod 501, which further absorbs and disperses the vibration energy, reduces the impact of vibration on the surrounding environment and structure, and reduces the generation and propagation of noise.
