Abstract

The invention discloses a noise-reduction type magnetic energy integrated transmission generator set, belongs to the technical field of noise reduction, and aims at solving the problem that the noise is large when a generator set operates in the prior art. The transverse ribs and vertical ribs on the bottom surface of the pressure plate enhance fluid shearing and energy dissipation efficiency. The double-layer flange design of the non-newtonian fluid reservoir constitutes a leak-proof barrier. The hinge at the bottom of the reservoir allows it to swing, providing the basis for the trigger mechanism. The buffer column absorbs the swing impact of the storage tank. The linkage mechanism formed by the limiting block, the traction spring and the clamping block can enable the clamping block to rapidly clamp the vibration source when the vibration is overlarge, and emergency mechanical locking is provided. The trigger mechanism formed by the coupler knuckle, the compression spring and the controller button converts swing into an electric signal to trigger early warning.

Description

Noise-reduction type magnetic energy integrated transmission generator set Technical Field The invention belongs to the technical field of noise reduction, and particularly relates to a noise reduction type magnetic energy integrated transmission generator set. Background The magnetic energy integrated transmission generator set is a power device integrating a driving motor, a magnetic transmission mechanism and a generator into a whole. The torque transmission, conversion and adjustment are realized by adjusting a magnetic field by utilizing a non-contact transmission principle such as magnetic coupling or a magnetic gear. The unit usually takes a driving motor as a prime motor, and transmits power to a generator through an intermediate magnetic energy integrated transmission device (such as a permanent magnet transmission, a magnetic coupler and the like) to finally output electric energy. The magnetic transmission mode avoids the direct contact of mechanical parts and has the advantages of stable transmission, overload protection, low maintenance requirement and the like. However, during operation of the unit, especially in response to variable load conditions, internal rotating magnetic field interactions, hysteresis effects and inevitably small air gap fluctuations still induce mechanical vibrations, which are transmitted through the structure to the housing and radiate as audible noise, constituting an inherent problem that needs to be overcome during operation thereof. The magnetic energy integrated transmission generator set can generate remarkable mechanical vibration and noise during operation, particularly during starting and load abrupt change. These vibrations are mainly due to unbalanced magnetic tension, gear mesh shock, and torque ripple of the internal rotating components and are transmitted and radiated outward through the equipment base. The traditional vibration and noise reduction method, such as installing a rubber pad or a passive damper on a base, has obvious limitations in that the rigidity and damping parameters are fixed. For continuous small-amplitude vibration in daily operation, the measures have a certain absorption effect, but the optimal vibration isolation efficiency is difficult to realize. The problem is that when the vibration damping element is faced with instantaneous large-amplitude impact vibration generated by starting, stopping or severe load change, the vibration damping element with fixed parameters cannot provide larger rigidity and damping matched with the vibration damping element, so that the vibration cannot be effectively restrained, even hard collision between equipment and a foundation can be caused, larger impact noise is generated, and the service life of the equipment is threatened. The prior art lacks an integrated vibration damping structure capable of automatically and continuously adjusting its own dynamic parameters according to the intensity of vibration and providing emergency braking in extreme cases. Therefore, a vibration and noise reduction scheme with self-adaptive and hierarchical protection capability is needed to cope with broadband vibration challenges of a generator set under complex working conditions, and to realize overall process noise control from energy dissipation to mechanical limit. The present invention seeks to mitigate or at least alleviate the above-mentioned problems by providing a noise reducing magnetic energy integrated drive generator set. Disclosure of Invention Aiming at one or more of the defects or improvement demands of the prior art, the invention provides a noise reduction type magnetic energy integrated transmission generator set, which has the advantage of being capable of reducing noise in a grading manner.
