Service life greatly shortens its service life, and the vibration of frequency converter will lead to noise generation, and noise will affect staff's
Health.
Summary of the invention
Aiming at the problems existing in the prior art, the utility model provide it is a kind of can damping and silencing frequency converter, can disappear
Except the noise of vibration and the generation of frequency converter.
To achieve the above object, the utility model provides following technical solution: it is a kind of can damping and silencing frequency converter, packet
Shell of frequency converter is included, the shell of frequency converter includes inner housing and outer housing, and damping is equipped between the inner housing and outer housing
Cavity, is equipped with damping device in the damping cavity, the damping device include be separately positioned on inner housing and outer housing and
Be open two opposite damping troughs, and damping spring is all equipped in two damping trough, and two damping trough is connected by connector, institute
The both ends for stating connector are respectively protruding into damping trough and inconsistent with damping spring, and the first silencing cavity is equipped in the inner housing,
It is equipped with the second silencing cavity in the outer housing, is all equipped with bloop in first silencing cavity and the second silencing cavity.
By adopting the above technical scheme, the damping device being arranged in the damping cavity, can eliminate frequency converter in the course of work
The noise that the vibration of middle generation, the first silencing cavity and the second silencing cavity can generate frequency converter is eliminated, to reach elimination frequency conversion
The purpose of the noise of vibration and the generation of device；Wherein, the inner housing passes through two damping troughs and both ends and subtracts with outer housing
The connector that is mutually connected of shake slot is attached, and connector is inconsistent with damping spring, can effectively be filtered and be absorbed frequency converter and is produced
Raw vibration, effectively eliminates the vibration of frequency converter generation, and protection frequency converter is unaffected；In addition, the first silencing cavity can incite somebody to action
The noise filtering that is issued inside inner housing is eliminated, and the second silencing cavity can be empty by the residual noise of the first silencing cavity and damping
The noise filtering of intracavitary sending is eliminated, and the two matches the noise that can eliminate frequency converter generation.
Further, the both ends of the connector are respectively equipped with fixture block, and the cross-sectional area of the fixture block is greater than damping trough
Opening.
By adopting the above technical scheme, setting can be such that fixture block is stuck in damping trough in this way, to guarantee connector and damping trough
Connection, avoid connector be detached from damping trough.
Further, the bloop is equipped with several bloops in honeycomb distribution.
By adopting the above technical scheme, when setting is utilized sound wave and propagates in porous sound-absorbing material or sound absorption structure in this way
The phenomenon that dissipating due to friction can convert thermal energy for sound, make gradually to decay by the noise of bloop, make an uproar to eliminate
Sound.
Further, damping device setting it is multiple and along damping cavity loop around setting.
By adopting the above technical scheme, setting may make damping device to can be used for filtering the vibration of all directions in this way, guarantee
Frequency converter is able to maintain stabilization in each orientation.
Further, two damping trough respectively with inner housing and outer housing integrated setting.
By adopting the above technical scheme, setting ensure that the connection between damping trough and inner housing, outer housing in this way, so that even
Connect it is stronger, it is not easily to fall off.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the damping device.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with accompanying drawings and embodiments.
It is as shown in Figure 1, 2 it is a kind of can damping and silencing frequency converter, including shell of frequency converter 1, the shell of frequency converter 1 wrap
Inner housing 11 and outer housing 12 are included, damping cavity 13, the damping cavity 13 are equipped between the inner housing 11 and outer housing 12
In be equipped with damping device 2, the damping device 2 includes being separately positioned on inner housing 11 and outer housing 12 and opening is opposite two
Damping trough 21 is all equipped with damping spring 22 in two damping trough 21, and two damping trough 21 is connected by connector 23, described
The both ends of connector 23 are respectively protruding into damping trough 21 and inconsistent with damping spring 22.Wherein, the inner housing 11 and shell
Body 12 is attached by the connector 23 that two damping troughs 21 and both ends are connected with 21 phase of damping trough, connector 23 and damping bullet
Spring 22 is inconsistent, can effectively filter and absorb vibration caused by frequency converter, effectively eliminate the vibration of frequency converter generation, protection
Frequency converter is unaffected.
It is equipped with the first silencing cavity 3 in the inner housing 11, is equipped with the second silencing cavity 4 in the outer housing 12, described first
