Description

Technical Field

[0001] The utility model relates to a waterproof ventilation shutter structure in the technical field of box-type transformer waterproofing. Background Art

[0002] Box-type substations, also known as prefabricated substations or prefabricated substations, are suitable for residential communities, urban public substations, bustling downtown areas, and construction power supplies. Because they generate significant heat during operation, shutters are installed on the window frames of box-type substations to dissipate heat. However, conventional shutters installed on box-type substation window frames are open at the bottom, which cannot withstand rainwater splashing upward from the cabinet. In the event of a storm, this water can splash into the box-type substation, damaging electrical components. Furthermore, these systems, when used with State Grid's standardized compact box-type substations, do not effectively dissipate heat and provide effective protection against dust and small animals. Utility Model Content

[0003] The purpose of the utility model is to provide a waterproof ventilation shutter structure for a box transformer, which can greatly achieve waterproof effect and prevent rainwater from splashing into the box transformer during heavy rain. This structure greatly improves the convection heat dissipation between the hot air inside the box transformer and the outside through the channel setting between the window blades, and can also effectively prevent dust and small animals from entering.

[0004] To achieve the above-mentioned purpose, the utility model provides a waterproof ventilation shutter structure for a box transformer, including an outer frame, the inner edge of the outer frame is provided with a back convex frame, the back convex frame is on the back of the outer frame, and sealing window blades and a plurality of rain-proof window blades are provided in the back convex frame, wherein the sealing window blades are arranged at the top of the back convex frame, and the rain-proof window blades are arranged below the sealing window blades and are arranged in sequence from top to bottom.

[0005] Compared with the prior art, the beneficial effect of the present invention is that the rain-proof window blades are used to prevent rainwater from splashing into the box transformer, and the sealing window blades can make up for the remaining margin of the rain-proof window blades, so that the entire back convex frame is filled, and the processing accuracy can also be reduced. Finally, the entire ventilation louver structure is fixedly connected to the window frame of the box transformer through the outer frame, which can greatly improve the waterproof effect, prevent rainwater from splashing into the box transformer during heavy rain, and improve the dustproof effect and the effect of preventing small animals from entering.

[0006] As a further improvement of the present invention, the rainproof window blade includes an inclined panel, an upper straight panel is provided on the top of the inclined panel, an upper horizontal panel is provided on the top of the upper straight panel, a lower straight panel is provided at the bottom of the inclined panel, ear panels are provided on both sides of the lower straight panel, and a lower horizontal panel is provided at the bottom of the lower straight panel. The ear panels are connected to the side edges of the back convex frame by means of bolts and nuts.

[0007] In this way, during installation, the lower horizontal plate of the upper rain-shield window leaf is opposite to the middle of the front side of the upper vertical sealing plate of the adjacent lower rain-shield window leaf, so that an upward oblique heat dissipation channel is formed between the two inclined panels of the adjacent rain-shield window leaves. The heat in the box transformer can be discharged outward through the heat dissipation channel. At the same time, the upper straight plate and upper horizontal plate of the lower rain-shield window leaf cooperate with the lower horizontal plate of the adjacent upper rain-shield window leaf to block rainwater splashing obliquely upward.

[0008] As a further improvement of the present invention, the sealing window blades include a vertical sealing plate, an upper horizontal sealing plate is provided on the top of the vertical sealing plate, a lower horizontal sealing plate is provided on the vertical bottom, and mounting plates are provided on both sides of the vertical sealing plate. The mounting plates are connected to the side edges of the back convex frame through the cooperation of bolts and nuts.

[0009] The overall structure of the sealing window leaf is similar to the lower part of the rainproof window leaf, so it can complement the upper part of the adjacent rainproof window leaf below, thereby blocking splashing rain water and making up for the gap between the rainproof window leaf and the top of the back convex frame.

[0010] As a further improvement of the present invention, a plurality of positioning posts are provided on the outer edge of the back side of the outer frame, and the positioning posts match the positioning holes provided on the box-type transformer window frame.

[0011] In this way, through the cooperation of the positioning columns and the positioning holes, the shutter structure can be quickly and accurately assembled with the window frame.

[0012] As a further improvement of the present invention, the back of the back convex frame is also covered with a stainless steel filter screen with 20 meshes or 30 meshes.

[0013] In this way, you can choose filters with different mesh sizes according to different environments to avoid clogging of the filter. For example, in places in the south where there are more poplar fluff, you can use a 30-mesh filter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention is further described below with reference to the accompanying drawings:

[0023] like Figure 1-7 The waterproof ventilation shutter structure for a box transformer shown in the figure includes an outer frame 2, the inner edge of the outer frame 2 is provided with a convex frame 6, the convex frame 6 is on the back of the outer frame 2, and the convex frame 6 is provided with sealing window blades 4 and a plurality of rainproof window blades 5, wherein the sealing window blades 4 are arranged at the top of the convex frame 6, and the rainproof window blades 5 are arranged below the sealing window blades 4 and are arranged in sequence from top to bottom.

[0024] The rainproof window blade 5 includes an inclined panel 10, an upper straight plate 9 is provided on the top of the inclined panel 10, an upper horizontal plate 8 is provided on the top of the upper straight plate 9, a lower straight plate 11 is provided at the bottom of the inclined panel 10, ear plates 12 are provided on both sides of the lower straight plate 11, and a lower horizontal plate 13 is provided at the bottom of the lower straight plate 11. The ear plates 12 are connected to the side of the back convex frame 6 by bolts and nuts.

[0025] The sealing window leaf 4 includes a vertical sealing plate 15, the top of which is provided with an upper horizontal sealing plate 14, the vertical bottom of which is provided with a lower horizontal sealing plate 17, and mounting plates 16 are provided on both sides of the vertical sealing plate 15. The mounting plates 16 are connected to the side edges of the back convex frame 6 by means of bolts and nuts.

[0026] A plurality of positioning posts 7 are provided on the outer edge of the back of the outer frame 2, and the positioning posts 7 match the positioning holes 3 provided on the box-type window frame 1. The back of the back convex frame 6 is also covered with a stainless steel filter screen of 20 mesh or 30 mesh.

[0027] In the present invention, the back convex frame 6 is installed on the back side of the outer frame 2 and protrudes outward. The sealing window leaf 4 is arranged on the top of the inner edge of the back convex frame 6. The mounting plates 16 at both ends are fixedly connected to the two sides of the back convex frame 6 by bolts and nuts. A number of rainproof window leaves 5 are installed in sequence below the sealing window leaf 4. The ear plates 12 at both ends of the rainproof window leaf 5 are fixedly connected to the two sides of the back convex frame 6 by bolts and nuts.

[0028] The middle portion of the back of the vertical sealing plate 15 of the sealing window leaf 4 faces the upper horizontal plate 8 of the adjacent rain-shielding window leaf 5. Thus, the vertical sealing plate 15 of the sealing window leaf 4 cooperates with the inclined plate 10 and the upper straight plate 9 of the adjacent rain-shielding window leaf 5 to block rainwater blowing in from the front and rainwater blowing diagonally downward, while rainwater blowing diagonally upward is blocked by the upper horizontal plate 8 of the rain-shielding window leaf 5 and the lower horizontal sealing plate 17 of the sealing window leaf 4. Therefore, the sealing window leaf 4 can not only complement the rain-shielding window leaf 5 to block rainwater, but also fill the gap between the rain-shielding window leaf 5 and the back convex frame 6, reducing the requirements for processing dimensional accuracy and making the overall appearance more beautiful.

[0029] Adjacent rain shield leafs 5, the back of the lower straight plate 11 of the upper rain shield leaf 5 is facing the upper horizontal straight plate of the lower rain shield leaf 5, and a heat dissipation channel is formed between the inclined panels 10 of the two adjacent rain shield leafs 5. The heat in the box transformer will be discharged outward along the heat dissipation channel (such as Figure 6 During a rainstorm, rainwater from the front will be directly blocked by the inclined panel 10, the upper straight panel 9, and the lower straight panel 11. Rainwater blowing diagonally downward will be blocked by the inclined panel 10 and the lower straight panel 11. As for rainwater blowing diagonally upward, it will be blocked by the lower horizontal panel 13 of the upper rain shield louver 5, the upper straight panel 9 of the adjacent lower rain shield louver 5, and the upper horizontal panel 8. This prevents rainwater from entering the transformer, whether from the front or from diagonally upward or diagonally downward, and ensures that the heat in the transformer is discharged outward through the heat dissipation channel.

[0030] The entire back side of the back convex frame 6 is covered with a stainless steel filter, which can effectively prevent small animals from entering the transformer box.

[0031] The utility model can prevent rainwater from all directions from entering the box transformer during heavy rain, and also allows the hot air inside the box transformer to form convection heat dissipation with the outside, and can effectively prevent dust and small animals from entering, greatly improving the protection level of the box transformer.

[0032] The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed herein, technicians in this field can make some substitutions and deformations of some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present invention.
