Description

Technical Field

[0001] The utility model belongs to the technical field related to box-type substations, and particularly relates to a ventilation top cover structure of a box-type substation. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device, which is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation. Box-type substations are mostly used for outdoor installation, which requires certain weather resistance requirements for the shell of the box-type substation. Box-type substations are usually large in size, with more internal electrical equipment and more heat generated. Usually, vents are opened on the side walls of the box-type substation for ventilation and heat dissipation, and the top cover is usually a closed structure, which has the following disadvantages in actual use:

[0003] First, most box-type substations are ventilated from their side walls, and the top covers are fixed and closed. However, heat itself rises, so a ventilation structure should be set on the top cover to ventilate and dissipate heat more effectively, but there is no corresponding ventilation structure on the conventional top cover;

[0004] Secondly, if ventilation structures such as vents are set on the top cover, it is necessary to ensure that it has sufficient weather resistance to meet the needs of use, and the top cover must be able to withstand the sun, wind and rain without affecting its internal structure;

[0005] Finally, in addition to the heat generated by the box-type substation itself, it is also necessary to isolate the entry of external heat. Conventional top covers are designed with a structure similar to that of a roof, and the heat insulation effect is poor. Utility Model Content

[0006] The utility model aims to provide a ventilation top cover structure of a box-type substation, which solves the problems of no ventilation structure on the top cover of the box-type substation, poor heat dissipation effect, the need for sufficient weather resistance when ventilating the top cover, and poor heat insulation effect of the top cover by arranging a top plate, a bottom plate, a triangular side plate, an air outlet 1, an air outlet 2, a vent, a fan, a filter 1, a filter 2, and an air outlet channel.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a ventilation roof structure of a box-type substation, comprising a bottom plate, a triangular side plate, a top plate, an air outlet channel and a fan, wherein the two opposite sides of the upper end of the bottom plate are fixed with triangular side plates, an air outlet is opened in the triangular side plate, and a filter is fixed in the air outlet;

[0009] A top plate is fixed to the inclined surfaces of the two triangular side plates in the same inclined direction, and the opposite surfaces of the two top plates are fixedly connected, and each top plate is penetrated with two equally distributed air outlets, and an air outlet channel is fixed to the inclined surface of the top plate outside each of the two air outlets, and a frame is fixed at the opening of the air outlet channel, and a second filter is fixed in the frame;

[0010] The bottom plate is vertically penetrated with symmetrically distributed ventilation holes, and an inclined fan is arranged above each ventilation hole.

[0011] Furthermore, the two fans are symmetrically distributed, and a mounting frame with an inclined upper surface is fixed to the bottom of the fan, the bottom of the mounting frame is fixed to the upper end surface of the base plate, and the mounting frame surrounds the top of the base plate outside the vent.

[0012] Furthermore, the air inlet end of the fan is close to the vent, and the air outlet end of the fan faces the top plate.

[0013] Furthermore, the side edges of the upper end of the bottom plate adjacent to the triangular side plates are welded and fixed to the corresponding lower inclined surfaces of the bottom plate.

[0014] Furthermore, a blocking bucket is fixed on one side of the triangular side plate close to the center of the bottom plate, and the blocking bucket surrounds the air outlet 1. The upper end of the blocking bucket and the side close to the air outlet 1 are both open, and the upper end of the blocking bucket is higher than the upper end of the air outlet 1.

[0015] Furthermore, the bottom end of the second air outlet is higher than the bottom end of the air outlet channel outside it, and the frame is screwed into the end of the air outlet channel through bolts passing through the end of the frame to be fixedly connected to the air outlet channel.

[0016] Furthermore, the length of the top plate is greater than the length of the bottom plate, and the width of the bottom plate is less than the farthest distance between the two top plates.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that there is no ventilation structure and poor heat dissipation effect on the top cover of the box-type substation by arranging a top plate, a bottom plate, a triangular side plate, an air outlet one, an air outlet two, a vent and a fan. Two triangular side plates are installed on the bottom plate, and two top plates are installed on the two triangular side plates to form a top cover structure of the box-type substation, which is then fixed on the main frame of the box-type substation, and the heat generated by the electrical equipment in the box-type structure is extracted by the fan and transported toward between the top plate and the bottom plate, and the heat is respectively exported outwards through the air outlet one and the air outlet two, and the fan is also located above the box-type structure, so as to quickly export the upwardly moved heat instead of exporting it from the side wall of the box-type structure of the box-type substation, which will inevitably cause a certain amount of heat to accumulate in the upper area of ​​the box-type substation, resulting in poor air circulation effect in the box-type substation and inconvenient ventilation and heat dissipation. The utility model takes in air from the side wall of the box-type substation and exhausts air from the air outlet one and the air outlet two, so as to facilitate rapid ventilation and heat dissipation.

[0019] The utility model solves the problem that the top cover needs to have sufficient weather resistance when ventilating by arranging a top plate, a triangular side plate, a filter screen 1, a filter screen 2, an air outlet 1, an air outlet 2, and an air outlet channel. A filter screen 1 is installed at one of the air outlets to reduce the entry of external dust, and a barrier bucket is arranged on the inner side of the air outlet 1, so that even if it rains outside and raindrops enter the air outlet 1, they will be blocked by the barrier bucket and guided out by the inclined surface of the barrier bucket, and no raindrops will enter the interior of the box-type substation. Secondly, an air outlet channel is arranged outside the air outlet 2 for ventilation to cover it, and a frame and a filter screen 2 are installed outside the air outlet channel to reduce the entry of external dust. Moreover, since the position of the air outlet 2 is higher than the bottom end of the air outlet channel, even if there is external rain impact, it will not directly enter the box-type substation, but will flow out along the inclined surface of the top plate below the air outlet 2, so that the entire top cover has good weather resistance, and while maintaining efficient ventilation, the influence of external sun, rain and wind can also be reduced.

[0020] The utility model solves the problem of poor heat insulation effect of the top cover by arranging a top plate, a bottom plate and triangular side plates; two triangular side plates are installed on the bottom plate, and then two top plates are installed on the two triangular side plates; the bottom plate is directly fixed on the box structure of the box-type substation, so a heat insulation chamber is formed between the top plate, the bottom plate and the triangular side plates, which is far more heat-insulating than increasing the thickness of the top cover, and effectively prevents the entry of external heat.

[0039] The side edge of the upper end of the bottom plate 1 adjacent to the triangular side plate 2 is welded and fixed to the corresponding lower inclined surface of the bottom plate 1; to increase the sealing effect, only the bottom of the bottom plate 1 is installed with the box structure of the box-type substation.
