Description

Waterproof assembly structure of outdoor busbar bridge box

Technical Field

The utility model belongs to the technical field of electrical equipment, concretely relates to outdoor generating line bridge case waterproof packaging structure.

Background

An electrical control system is usually provided with a plurality of switch cabinets, the switch cabinets are arranged into a plurality of rows, and buses of the switch cabinets in different rows need to be correspondingly connected by a cross-row bus bridge. The bus bridge is provided with a bridge box, the box body of the bus bridge box comprises a box cover and a box wall, and the box cover and the box wall are made of metal plates.

The bus bridge box of a partial switch cabinet (particularly a medium-voltage cabinet) needs to be arranged in an outdoor open environment, so that the prevention of rainwater infiltration becomes a problem to be considered seriously. The welding part of the metal plate in the open environment is easy to rust and seep water, so the waterproof part of the metal plate of the bus bridge box in the open environment is generally not suitable for welding.

The existing installation mode of the outdoor bus bridge box has the waterproof function to be improved, and is shown in the following aspects:

firstly, the fixed connection mode between the cover plate 1 and the box wall 2 of the outdoor bus bridge box is as shown in fig. 1, the cover plate 1 is provided with a vertical cover edge 10, the cover edge 10 and the top edge of the box wall 2 are respectively provided with a mounting hole 4, the cover edge 10 and the top edge of the box wall 2 are fixedly connected through a bolt penetrating through the mounting hole 4, but rainwater can also penetrate into the bridge box through the mounting hole 4. In addition, in the case of a storm, since the air pressure outside the bridge box is greater than the air pressure inside the bridge box, rainwater may be blown into the inside of the bridge box along the gap between the cover rim 10 and the top rim of the box wall 2, as indicated by the arrows in fig. 1;

two, because the length of striding the line generating line bridge is great, therefore the case lid need be lapped by a plurality of apron 1 front and back, and front and back overlap joint position utilizes the bolt and the nut fixed connection who passes mounting hole 4 equally, as shown in fig. 2, like this, the rainwater passes through mounting hole 4 infiltration entering bridge box the inside easily, and easy ponding on the case lid apron 1 moreover, ponding still can be along the gap infiltration bridge box the inside of front and back overlap joint position.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned shortcoming and provide a waterproof package assembly of outdoor generating line bridge case, it need not adopt the welding, can ensure moreover that the rainwater can not permeate box inner chamber the inside.

The purpose can be realized according to the following scheme: a waterproof assembly structure of an outdoor bus bridge box comprises a box body made of metal materials, wherein the box body is provided with a box cover and box walls, and the box cover is formed by longitudinally splicing a plurality of metal cover plates; the method is characterized in that: in every two adjacent metal cover plates in front and at the back, a first vertical folded edge which is bent upwards is formed at the back edge of the front metal cover plate and the front edge of the back metal cover plate respectively, each first vertical folded edge is also connected with a longitudinal folded edge integrally, and the planes of the first vertical folded edge and the corresponding longitudinal folded edge form a sharp included angle; the longitudinal folded edge of the front metal cover plate is bent forwards, and the longitudinal folded edge of the rear metal cover plate is bent backwards; the longitudinal folded edges of the front and the rear metal cover plates are covered with a strip-shaped cover, the strip-shaped cover comprises a cover main plate and cover edges positioned at the front and the rear sides of the cover main plate, and the longitudinal section of the cover main plate is in a V shape with a high middle part and lower front and rear sides; the V-shaped cover main board is attached to the upper parts of the longitudinal folded edges of the front and rear metal cover plates, the cover main board and the longitudinal folded edges are respectively provided with a first mounting hole, and the cover main board and the longitudinal folded edges are locked together by utilizing a first vertical bolt penetrating through the first mounting hole;

the transverse edge of each metal cover plate is provided with a second vertical folded edge which is bent downwards, the lower end of each second vertical folded edge is also integrally and vertically connected with a horizontal inner folded edge which is bent inwards, the top edge of the tank wall is also bent downwards by 180 degrees to form a tank wall folded edge, and the tank wall folded edge is attached to the outer surface of the tank wall in parallel; the lower end of each box wall folded edge is also integrally and vertically connected with a horizontal outer folded edge which is bent outwards; the horizontal inner folding edge of the metal cover plate is attached to the upper portion of the horizontal outer folding edge of the box wall, the horizontal inner folding edge of the metal cover plate and the horizontal outer folding edge of the box wall are respectively provided with a second mounting hole, and the metal cover plate and the box wall are locked together by a second vertical bolt penetrating through the second mounting hole.

Preferably, each metal cover plate is in an inverted V shape with a lower left side and a lower right side and a higher middle in a transverse section.

The term "inwardly" refers to the right for the member on the left side of the housing; for the member located on the right side of the cabinet, this is to the left.

By "outward," it is meant to the left for the member on the left side of the case; for the member located on the right side of the cabinet, this is to the right.

The utility model has the advantages of it is following and effect:

in the assembly structure of the utility model, the front and the rear metal cover plates of the box cover are connected by bolts without welding, the box cover and the box wall are connected by bolts without welding, and the mounting holes of the bolt connection structure can not flow into the inner cavity of the box even if water seeps; specifically, the tank wall folded edge, the horizontal inner folded edge and the second vertical folded edge of the metal cover plate are combined to form a longitudinal groove, so that even if water seeps through a second mounting hole corresponding to the second bolt, the water only flows into the longitudinal groove, and does not flow into the inner cavity of the tank body; on the other hand, even if water seeps from the first mounting hole corresponding to the first bolt, the water only flows to the upper surface of the metal cover plate and does not flow to the inner cavity of the box body.

And secondly, because the first vertical folding edge and the plane where the corresponding longitudinal folding edge is located form an acute included angle, even if the first mounting hole of the cover main board is supposed to seep water, rainwater flows to the upper surface of the longitudinal folding edge through the first mounting hole of the cover main board and then does not flow into the inner cavity of the box body through a gap of the first vertical folding edges of the front and the rear adjacent metal cover plates.

And the metal cover plate is in an inverted V shape with the left side and the right side being low and the middle being high on the transverse section, so that the quick drainage is facilitated, the space of the bridge box is increased, and the heat dissipation of the copper bar is facilitated.
