Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes vibrations and cover 3 and have the base 1 in damping chamber 2, shakes to cover 3 and be enclosed within versatilely on the damping chamber 2, is provided with spring 4 in damping chamber 2, one end of spring 4 is against on the bottom in damping chamber 2, and the other end is against vibrations and covers on 3 the roof.
The utility model is performed such installation: be example with the dry-type transformer, the utility model is installed under the support that base 1 of the present utility model is fixed with ground, dry-type transformer places on the support.Dry-type transformer covers 3 because of vibrating transmission to the vibrations that Ac produces, vibrations cover 3 makes vibrations obtain buffering under the effect of spring 4, significantly having weakened the low-frequency noise that produces because of vibrations, is that part of low-frequency noise that relies on air or dependence building to propagate all significantly obtains weakening.
As shown in Figure 2, vibrations covers 3 top and are provided with support installation adjusting screw 5.The purpose that support is installed adjusting screw 5 is in order to adjust the height between the utility model and the transformer bracket, thereby makes transformer maintenance level.
As shown in Figure 2, spring 4 can be a cylindroid helicalcoil compression spring 6, and spring 4 also can be two, and one is cylindroid helicalcoil compression spring 6, and another root is a load Regulation spring 7, and load Regulation spring 7 is positioned at the inside of cylindroid helicalcoil compression spring 6.In two springs 4, cylindroid helicalcoil compression spring 6 is a main spring, load Regulation spring 7 is a secondary spring, Different Weight load requires different for the elasticity coefficient of damping spring, two groups of springs selecting different load-bearing ratios as required adopt two groups of springs 4 can increase flexibility of the present utility model to reach requirement.
As shown in Figure 2,3 top is covered in vibrations and the bottom in damping chamber 2 respectively is provided with a ring baffle 8, and spring 4 is positioned at ring baffle 8.The purpose of She Zhiing is to prevent to be offset about spring 4 from taking place like this, and an in the vertical direction takes place flexible.
As shown in Figure 2, vibrations are covered 3 inwall place and are provided with and the corresponding annular groove 9 of the outer wall in damping chamber 2, are provided with damping ring pad 10 in the annular groove 9.The effect of damping ring pad 10 is the frictions of covering between 3 inwalls and damping chamber 2 outer walls in order to reduce to shake, thereby reduce the noise that produces because of friction, simultaneously damping ring pad 10 can also be converted into the mechanical energy in the vibrations process heat energy dissipation and falls, and the energy that reduces to shake reaches the purpose of damping.
