Shockproof transformer box
Technical Field
The invention relates to the technical field of transformer boxes, in particular to a shockproof transformer box.
Background
The information disclosed in this background of the invention is only for enhancement of understanding of the general background of the invention and is not necessarily to be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
A power transformation box in a broad sense generally refers to a device that can realize a place for converting, concentrating and distributing voltage and current in a power system, which has been widely used as an important part of the power system. For most large-sized transformer boxes, the size and the weight are large, vibration is inevitable in the installation and transportation process, and especially in the transportation process of the large-sized transformer boxes in mountainous areas, the requirement on the vibration prevention function of the transformer boxes is higher. Conventionally, there are many types of transformer boxes having a vibration-proof function, for example, a vibration-proof type transformer box disclosed in patent document 201910470306.6; 201920542870.X discloses a transformer box with a buffering shockproof structure and the like. However, the inventor of the present invention found that the shock-proof transformer box of this type generally offsets the impact force generated by the shock through the hard contact between the elastic body and the transformer box, however, a part of the impact force is still transmitted from the bottom of the transformer box to the electrical components therein, which still risks the damage of the transformer box in terms of transportation and installation of the transformer box under the working condition of large amplitude of shock, and therefore, it is necessary to further research into the transformer box capable of overcoming the above problems.
Disclosure of Invention
In view of the above problems, the present invention is directed to provide a shockproof transformer box, which can well avoid the problem that the impact force generated by the vertical vibration is transferred from the bottom of the transformer box to the electrical components in the transformer box, so that the overall shockproof performance is effectively improved, and the shockproof transformer box is particularly suitable for protecting the transformer box during bumpy transportation.
In order to achieve the purpose, the invention adopts the following technical means:
a shockproof transformer box comprises a base, a box body, a convex block and a damping structure; wherein: the upper end of the base is provided with an opening; the protruding block is annular, the box body penetrates through an opening in the middle of the annular protruding block and then is fixed with the protruding block, and the protruding block is located on the side wall of the lower portion of the box body.
The damping structure comprises at least two groups of supporting rods, elastic parts, cushion blocks and annular brackets, wherein the supporting rods are vertically and symmetrically arranged in the base, one end of each supporting rod is fixed on the bottom surface of the base, and the other end of each supporting rod extends out of a port of the base. The elastic component is sleeved on the supporting rod, the cushion block is sleeved on the supporting rod through the through hole of the cushion block, and the upper end of the elastic component is fixed on the lower surface of the cushion block. An opening is formed in the middle of the annular bracket, and the size of the opening is that the box body can pass through but the protruding block cannot pass through; the annular bracket is also provided with a through hole corresponding to the support rod, the edge of the annular bracket is bent downwards to form a rain skirt, and the rain skirt surrounds the outer side of the upper port of the base; the box body is hung on the annular bracket through the matching of the convex block and the opening on the annular bracket.
Compared with the prior art, the invention has the following beneficial effects:
(1) the shock-proof transformer box designed by the invention is of a suspension type structure, the lower part of the box body for loading electrical elements is integrally suspended in the base, the shock-proof advantage of the structure is that the lower bottom surface of the box body is not in direct contact with the base, and the impact force generated in the process of vertical vibration cannot be transmitted to the electrical elements through the bottom surface of the box body, so that the damage to the bottom surface of the box body and the electrical elements can be well avoided.
(2) When the shock-proof transformer box designed by the invention offsets the impact force generated by shock, most of the impact force is consumed through the elastic component, and the rest of the impact force can be dispersed on the side wall of the box body through the annular bracket and the convex block, so that the force can be dispersed more uniformly, the point-to-point impact resistance can be avoided, and the box body can be prevented from being impacted and deformed under a large impact force; and when the impact force is dispersed on the box through the annular bracket and the convex block, the box can be shaken up and down through continuation and gradually consumes the box and the impact force with the elastic component, so that the box is prevented from absorbing the impact force through hard resistance, and in fact, the box is often damaged through the hard resistance absorption impact force found through tests.
(3) According to the invention, the lower edge of the annular bracket is bent downwards to form the rain skirt, the suspension of the box body and the rain prevention of the base are combined together, rainwater can be prevented from being poured into the base through the action of the rain skirt, and the damage of the base can not only influence the damping effect, but also influence the overall stability of the box body due to the important damping structure arranged in the base.
