Description

Rainproof facility suitable for outdoor cabinet

Technical Field

The invention relates to a rainproof facility suitable for an outdoor cabinet.

Background

The outdoor cabinet of transformer substation is of a great variety, including terminal box, collection accuse case, mechanism case and so on, and the return circuit that electronic components and binding post in these cabinets constitute has guaranteed transformer substation's protection action, functions such as signal transmission, plays crucial effect to the steady operation of transformer substation. If components and terminals in the box are affected with damp, the protection device is likely to malfunction and refuse to operate, so that a circuit is tripped, equipment is damaged, and the stable operation of a power grid is seriously threatened. Usually rainy day, the staff can not open outdoor cabinet easily, just in order to prevent that the rainwater from drenching into incasement portion, causes components and parts, binding post to wet and the short circuit.

However, in the process of the operation of the power transformation equipment, the outdoor cabinet is opened to operate the air switch, and in order to not delay the operation time, the cabinet must be opened to operate the air switch even in rainy days; during planned maintenance, no matter primary maintenance, high-voltage test or secondary work, the outdoor control box, the mechanism box and the terminal box need to be opened for a long time to be matched, and the maintenance period can be seriously influenced if long-time rain occurs; under the condition that meets needs emergency repair, maintainer need take simple and easy canopy with cloth or raincoat and just dare to open the cabinet door and realize emergency repair even, and work efficiency is lower.

At present, the outdoor cabinet of transformer substation does not have actual rain-proof facility, and the rain-proof eaves similar to the eave has been installed at partial outdoor cabinet top, and it can prevent rainwater to a certain extent to flow down along the box top and instil into the cabinet when the chamber door is opened inside, nevertheless because of the eaves limit is short and small, and is at most than the wide 5cm of cabinet usually, can't prevent when opening the chamber door rainwater directly drench in the cabinet under the effect of wind power.

Disclosure of Invention

The invention improves the problems, namely the technical problem to be solved by the invention is that the existing outdoor cabinet of the power station has no actual rainproof facilities, and rainwater directly falls into the cabinet under the action of wind force in the maintenance process to cause the dampness and short circuit of components and terminals.

The specific embodiment of the invention is as follows: the utility model provides a rain-proof facility suitable for outdoor cabinet, is including being fixed in the box at cabinet top, the umbrella body that can outwards expand has in the box, the umbrella body is fixed with ability folding cloth of keeping out rain between each rib including articulating in the rib of box, the box front side has and is used for spacing umbrella body to prevent the bolt that the umbrella body was returned, the box top have can with bolt complex slot, the cloth of keeping out rain between outside rib and the adjacent rib end have the jack that passes with the confession bolt, the jack is located the box.

Furthermore, the box body comprises an inner cavity for accommodating the umbrella body, the box body is integrally closed, and the front side of the box body is hinged with a box cover capable of closing the box body.

Furthermore, a vertical fixed shaft is fixed on the inner side of the box body, the fixed shaft corresponds to the number of the umbrella ribs, and the rear sides of the umbrella ribs are sleeved on the fixed shaft to realize the hinging of the umbrella ribs and the box body.

Furthermore, the inner side surface of the rain shielding cloth is provided with an insert pocket sleeved outside the umbrella ribs.

Furthermore, the umbrella rib positioned at the innermost side is fixedly connected with the box body.

Furthermore, a handle is arranged on the box cover.

Compared with the prior art, the invention has the following beneficial effects:

(1) the rain-proof cloth that the utilization can expand, with low costs, the suitability is strong, thereby can effectively realize avoiding component and binding post in the rainwater drenching the cabinet to sheltering from of cabinet in the time of rainy.

(2) The waterproof cloth is foldable, the problem that if the waterproof awning is unfolded for a long time, the waterproof cloth is easily blown off by typhoon and becomes a floating object influencing the operation of a transformer substation, so that potential safety hazards are caused is avoided, the waterproof cloth is convenient to store, simple in structure, convenient to install and low in process manufacturing cost, and the waterproof awning can be well stored through the design of the box body, is convenient to take and use, and prolongs the service life.

(3) The cabinet without the rain awning can conveniently and quickly complete transformation work, and complex problems of large wiring change, circuit outage and the like caused by replacement of the cabinet are avoided.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-5, a rain-proof facility suitable for outdoor cabinet, including being fixed in the box 10 at 100 tops of cabinet, the umbrella body 210 that has the ability to expand outwards in the box, the umbrella body is including articulating the rib 220 in the box, is fixed with folding waterproof cloth 230 between each rib 220, the box front side has the bolt 30 that is used for spacing umbrella body to prevent that the umbrella body from withdrawing, the box top has can with bolt complex slot, the terminal jack 231 that has for the bolt to pass of waterproof cloth between outside rib 221 and the adjacent rib, the jack is located the box.

In this embodiment, the box 10 includes an inner cavity for accommodating the umbrella, and the box is integrally closed and hinged to a box cover 110 capable of closing the box.

In this embodiment, the used bolt is a common bolt for locking doors and windows, the bolt seat 301 of the bolt 30 is fixedly mounted on the inner arm of the box body, the rib 222 located at the innermost side is fixedly connected with the box body, and the upper end of the bolt penetrates through the jack 231 and extends into the slot at the top of the inner side of the box body to limit the position of the rib 221 at the outermost side, so that the umbrella body opened in the maintenance process cannot be retracted inwards under the influence of external force such as wind power.

In this embodiment, a vertical fixing shaft 120 is fixed on the inner side of the box body 10, the fixing shaft 120 corresponds to the number of the umbrella ribs, and the rear side of the umbrella ribs is sleeved on the fixing shaft to realize the hinging of the umbrella ribs and the box body, so that the limitation of each umbrella rib can be realized by using rivets and bolts except for the mode of adopting the fixing shaft 120, and the inner side ends of the umbrella ribs can be rotatably fixed on the inner side of the box body.

In this embodiment, the inner side of the rain-shielding cloth 230 has an insertion bag 232 covering the outside of the umbrella rib, and the outer end of the umbrella rib is inserted into the insertion bag 232 to connect with the rain-shielding cloth 230, thereby fixing the rain-shielding cloth 230.

To facilitate opening of the lid 110, the lid has a handle 111.

During the use, open the case lid earlier, the rib 221 that the pulling is the outside expandes whole umbrella body, thereby later insert slot 110 with bolt 30 and fixed spacing umbrella body's expansion, later carry out the maintenance of cabinet, extract bolt 30 after the maintenance to cover the case lid in accomodating the umbrella body to box 10.
