Detailed Description

In order to make the objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. Several embodiments of the utility model are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In the present invention, unless otherwise explicitly stated or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations. The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. "beneath," "under" and "beneath" a first feature includes the first feature being directly beneath and obliquely beneath the second feature, or simply indicating that the first feature is at a lesser elevation than the second feature. The terms "vertical," "horizontal," "left," "right," "up," "down," and the like are used for descriptive purposes only and are not intended to indicate or imply that the referenced devices or elements must be in a particular orientation, configuration, and operation, and therefore should not be construed as limiting the present invention.

The utility model is described in detail below with reference to the figures and examples.

Referring to fig. 1 and 2, the present invention provides a transformer protection device for an airport, including a protection cover 1 and a protection barrel 2 for containing a transformer; the protective cover 1 is covered at the opening at the top of the protective barrel 2; the edge of the protective cover 1 is provided with an inclined part 3; the inclined portion 3 is annular, and the inclined surface of the inclined portion 3 extends from the top surface of the protective cover 1 to the bottom surface of the protective cover 1.

Specifically, in the construction standard of the airport, the transformer of the lighting device needs to be placed in the protective barrel 2, then the protective barrel 2 is poured in cement for fixing, the protective cover 1 needs to be covered on the protective barrel 2, and the protective cover 1 clearly indicates in the standard that the protective cover needs to be higher than the ground or than a poured cement block, so that the maintenance of people can be facilitated. However, in case of heavy snow weather, the snow on the ground needs to be cleaned by using a snow scraper due to the large area of the airport; or for the lawn with larger area on the airport, the lawn also needs to be trimmed by using a large weeding vehicle, so that when the working part of the snow cleaning equipment or the weeding equipment contacts the edge of the protective cover 1, the lawn collides with the protective cover 1, the protective barrel 2 and the transformer equipment inside the protective cover are pulled up together, the power supply of the airport is further influenced, and the normal rising and falling of the airport are further influenced in severe cases. Also, the present invention can prevent people from being stumbled and injured by the protective cover 1 raised above the ground.

Therefore, the inclined part 3 is added around the protection device, when snow cleaning equipment or weeding equipment is needed to be used on an airport, the snow cleaning equipment or the weeding equipment can slide over the top surface of the protective cover 1 under the action of the inclined part 3 around the protective cover 1 after contacting the protective cover 1 higher than the ground, so that the frontal collision with the side wall of the protective cover 1 is avoided, and power supply equipment on the airport is protected.

Furthermore, a plurality of first screw holes 11 are formed in the protective cover 1; the protective barrel 2 is provided with a plurality of second screw holes 21 which correspond to the first screw holes 11 one by one; the protective cover 1 and the protective barrel 2 are connected with each other by bolts.

Further, the edge of the opening of the protection barrel 2 is provided with a connecting portion 22, the bottom surface of the protection cover 1 is provided with a limiting groove 12 matched with the connecting portion 22, and under the condition that the protection cover 1 is covered on the protection barrel 2, the connecting portion 22 is accommodated in the limiting groove 12.

Furthermore, a through hole for passing a wire is further formed in the side wall of the protection barrel 2.

Further, an included angle between the inclined surface of the inclined portion 3 and the bottom surface of the inclined portion 3 is 20 ° to 75 °. An excessive angle may approach the vertical plane, resulting in insufficient smoothness of the transition, still easily causing the protective cover 1 and the snow scraper to collide with each other. While an excessively small angle would lengthen the inclined portion 3, reduce the thickness of the inclined portion 3, make it inconvenient to transport and produce,

further, the inclined surface of the inclined part 3 is an arc-shaped structure which is concave inwards; this further improves the smoothness of the transition between the floor and the protective cover 1.

Further, the inclined portion 3 is integrally molded with the protective cover 1.

Further, the inclined portion 3 is cast separately from the protective cover 1, and the inclined portion 3 is screwed to the protective cover 1. Specifically, the present application can also achieve the protection effect by separately manufacturing the inclined portion 3 and installing the inclined portion 3 around the existing protection cover 1, which belongs to the routine improvement of those skilled in the art and shall fall within the protection scope of the present application.

To sum up, the present application provides a transformer protection device that can effectively prevent to collide, through set up slope 3 around transformer visor 1 to prevent that snow clearer or weeder from colliding with visor 1 and damaging the transformer.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
