A kind of electric switch damping device
Technical field
The present invention relates to damping device, relate in particular to a kind of electric switch damping device.
Background technology
Existing electric switch installation form is and is directly installed on power distribution cabinet, without damping protection.In earthquake etc. during compared with big bang, due to its vibrations, to have direction of earthquake source uncertain, shockproofness large (distribution box cabinet acceleration can reach 6g in the time of larger earthquake), vibrations number of times is uncertain, there is the features such as vibrations repeatedly, electric switch inner contact is very easily given a shock and causes the undesired contact in contact or disconnection, uses thereby affect electric switch.The present invention adopts seismic isolation technology and energy-dissipating and shock-absorbing technology effectively to absorb vibration energy, prevents that electric switch is given a shock the rear switch that affects and uses.
Summary of the invention
Object of the present invention provides a kind of mode by double-absorption to reduce the vibrations that electric switch is subject to regard to being, has effectively avoided electric switch to be given a shock the electric switch damping device of the abnormal problem of rear electric shock vibrations work.
To achieve these goals, the technical solution used in the present invention is: a kind of electric switch damping device, comprise power distribution cabinet coupling part, buffer layer, electric switch coupling part, described power distribution cabinet coupling part and electric switch coupling part respectively with the upper and lower surface bonding by Vulcanization of buffer layer, described electric switch coupling part or power distribution cabinet coupling part have been provided with the built-in fitting of firm effect, in described buffer layer, be provided with metal clips, the two ends of described metal clips are fixedly connected with power distribution cabinet coupling part, or the two ends of metal clips are fixedly connected with electric switch coupling part,
As preferably, described built-in fitting is fixedly connected with electric switch coupling part or power distribution cabinet coupling part;
As preferably, described built-in fitting is metal embedded part, and longitudinal section is in T shape;
As preferably, described metal clips is wavy or dentation;
As preferably, metal clips in the shape of a spiral;
As preferably, described buffer layer is rubber damping buffer layer.
Compared with prior art, the invention has the advantages that: reduce by the mode of double-absorption the vibrations that electric switch is subject to, effectively avoided electric switch to be given a shock the abnormal problem of rear electric shock vibrations work.Can be used for the operational environment that vibrations are larger, also can be used for electric switch electricity piece in addition.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1, electric switch coupling part; 2, power distribution cabinet coupling part; 3, vibration absorber; 4, metal clips; 5, built-in fitting.
Embodiment
Embodiment: the invention will be further described below in conjunction with Fig. 1, a kind of electric switch damping device, comprise power distribution cabinet coupling part 2, buffer layer 3, electric switch coupling part 1, electric switch coupling part 1 and power distribution cabinet coupling part 2 are made up of metal material, be used for connecting electric switch and power distribution cabinet, described buffer layer 3 is rubber damping buffer layer, bonding by Vulcanization is carried out with rubber damping buffer layer in electric switch coupling part 1 and power distribution cabinet coupling part 2, buffer layer 3 is by electric switch part 1, power distribution cabinet coupling part 2 connects in aggregates, making vibrations can be directly passed to buffer layer 3 absorbs, described electric switch coupling part 1 or power distribution cabinet coupling part 2 have been provided with the built-in fitting 5 of firm effect, strengthen bonding by Vulcanization effect, prevent electric switch coupling part 1, power distribution cabinet connect with buffer layer 3 between the disengagement under high shockproofness impact repeatedly of bonding by Vulcanization interface, thereby affect buffer layer 3 assimilation effects, described built-in fitting 5 is fixedly connected with electric switch coupling part 1 or power distribution cabinet coupling part 2, described built-in fitting 5 is metal embedded part 5, and longitudinal section is in T shape, stable connection difficult drop-off, described built-in fitting 5 tops are positioned near sheet metal crest, when vibrations occur, crest location vibrations are larger, and the effect of the structural strength that strengthens crest position can be played in built-in fitting 5 tops, can also absorption portion vibrations, described metal clips 4 is wrapped by buffer layer 3, the two ends of described metal clips 4 are fixedly connected with power distribution cabinet coupling part 2, or the two ends of metal clips 4 are fixedly connected with electric switch coupling part 1, can be according to electric switch volume and weight, change buffer layer 3 materials or on buffer layer 3, increase shock absorbing structure, as increased honeycomb hole etc., regulate buffer layer 3 dampings.In the time running into vibrations, shock wave passes to buffer layer 3 by electric switch coupling part 1 or power distribution cabinet coupling part 2, and wherein larger vibrations are absorbed by metal clips 4, and vibrations less and repeatedly are absorbed by buffer layer 3.Reduce by the mode of double-absorption the vibrations that electric switch is subject to, effectively avoided electric switch to be given a shock the abnormal problem of rear electric shock vibrations work.
Above a kind of electric switch damping device provided by the present invention is carried out to detailed introduction, applied specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, to be possible to change of the present invention and improvement, and can not exceed design and the scope of accessory claim defined, in sum, this description should not be construed as limitation of the present invention.
