The cover plate covers the base to avoid the phenomenon of water entering the cable trench.

Description

A substation ventilated cable trench cover

technical field

The utility model relates to the technical field of electric power facilities, in particular to a substation ventilation type cable trench cover plate.

Background technique

The substation cable trench cover plate is the main way for daily cable trench inspection and maintenance. At present, it is basically made of cement. Since the cable trench is located under the ground, the humidity is high, and the cable trench is directly connected to the terminal box, mechanism box, power box, switch cabinet, etc. of the power equipment. Short circuit, grounding, rust, equipment aging and other phenomena, it is necessary to frequently lift the cover of the cable trench near the cabinet for ventilation, so as to ensure that the humidity in the cable trench is not high, and the moisture is not easy to penetrate into the box of the power equipment from the cable trench. In the cabinet, however, the cemented cover is very heavy and difficult to open. It requires two people to use crowbars or iron hooks to operate, which is time-consuming and laborious. Moreover, the cover is often opened, which will cause the opened cover to be combined with the surrounding adjacent covers. The location is not tight enough, and it will cause water dripping into the cable trench in rainy days.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide a substation ventilation type cable trench cover plate with simple structure and good air permeability.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A substation ventilated cable trench cover plate, which includes a cover plate and a base, the base is composed of an angle iron frame and a stainless steel mesh plate installed in the angle iron frame, and movable parts are arranged between the upper parts of the angle iron frame and the cover plate The support rod, the cover plate and the angle iron frame are connected through a rotating shaft.

The ventilated cable trench cover plate of the substation is provided with a groove on the edge of the upper surface of the cover plate, and a pull ring is installed in the groove.

The ventilated cable trench cover plate of the substation has vertically downward folded edges around the cover plate, the folded edges are located inside the angle iron frame, and a shock-absorbing sealing strip is arranged between the angle iron frame.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following advantages:

The ventilated cable trench cover plate of the substation has a simple structure. The cover plate is made of glass fiber reinforced plastic cover plate, which is light in texture. When the cable trench needs to be ventilated, the cover plate can be lifted by pulling the pull ring, and the cover plate can be supported by the movable support rod. , and it is conducive to the opening of the cover plate. The moisture in the cable trench is easily evaporated through the mesh holes on the stainless steel mesh plate to achieve the purpose of ventilation. The cover plate closes the base to avoid the phenomenon of water entering the cable trench.

Description of drawings

Fig. 1 is the structural representation of the utility model;

In the figure: 1 - cover plate; 2 - movable support rod; 3 - support plate; 4 - stainless steel mesh plate; 5 - angle iron frame; 6 - folding edge.

Detailed ways

The technical solution of the utility model will be described in further detail below through the embodiments and in conjunction with the accompanying drawings.

As shown in Figure 1, the substation ventilated cable trench cover plate includes a cover plate 1 and a base, the base is composed of an angle iron frame 5 and a stainless steel mesh plate 4 installed in the angle iron frame, and the upper parts of the angle iron frame on both sides A movable support rod 2 is arranged between the cover plate, and the movable support rod is hinged by two connecting rods. One end of the movable support rod is hinged to the cover plate, and the other end is hinged to the support plate 3 provided on the inside of the angle iron frame. The plate and the angle iron frame are connected by a rotating shaft; a groove is arranged on the edge of the cover plate, and a pull ring is installed in the groove.

The above-mentioned cover plate has a vertically downward folded edge 6 all around, and the folded edge is located inside the angle iron frame, and a shock-absorbing sealing strip is arranged between the angle iron frame and the angle iron frame.

When the cable trench needs to be ventilated, pull the pull ring to lift the cover plate, and the movable support rod will support the cover plate. The moisture in the cable trench will evaporate through the mesh of the stainless steel mesh plate, and it can prevent small animals from entering the cable trench.

One end of the above-mentioned movable support rod is hinged to the cover plate, and the other end can also be hinged to the stainless steel mesh plate.
