Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment auxiliary technology, in particular to a vibration reduction and noise reduction device for electromechanical equipment. Background Art

[0002] In recent years, my country has increasingly higher requirements for the environmental quality of construction projects, especially for buildings such as schools, hospitals, comprehensive office buildings, and high-end hotels, which have very strict requirements for noise and vibration control. The source of noise and vibration is mainly the equipment room, because the equipment room is equipped with refrigeration units, air conditioning circulating water pumps, air handling units, various fans, cooling towers, transformers, HVAC and water supply and drainage and other power electromechanical equipment. However, in actual use, electromechanical equipment with similar structures still have many defects, such as: when the electromechanical equipment is in operation, the inertial force of rotation and the disturbing force generated by eccentric imbalance will cause the equipment components to generate forced vibration, and generate vibration through the equipment base, pipelines and the connection parts of the building, causing greater noise, and therefore it is necessary to design a shock-absorbing and noise-reducing device for electromechanical equipment. Utility Model Content

At this time, the connecting spring is deformed, and the sliding friction between the connecting block and the inner wall of the connecting groove can provide a certain damping effect for the electromechanical equipment body. When the connecting block moves, the damping gear engages with the damping rack in the rotating mouth. At this time, the damping gear will rotate, and the engagement between the damping gear and the damping rack can provide a certain damping effect on the vibration of the electromechanical equipment body.

The setting of the rotating plate can apply force to the rotating plate by the inner wall of the tooth groove when the damping gear rotates, and the rotating plate will rotate in conjunction with the connecting shaft, and the friction and impact force between the two can provide damping effect for the equipment.

[0010] Preferably, a shock-absorbing pad surrounding the electromechanical equipment body is fixedly connected to the top of the inner wall of the bottom shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the electromechanical equipment body vibrates, the connecting block can slide in the inner wall of the connecting groove. The sliding of the connecting block can change the angle of the two connecting plates. At this time, the connecting spring is deformed, and the sliding friction between the connecting block and the inner wall of the connecting groove can provide a certain damping effect for the electromechanical equipment body. When the connecting block moves, the damping gear meshes with the damping rack in the rotating mouth. At this time, the damping gear will rotate, and the engagement between the damping gear and the damping rack can provide a certain damping effect on the vibration of the electromechanical equipment body.
