Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, specifically a dustproof prefabricated substation enclosure. Background Technology

[0002] A prefabricated substation is a combination of high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment, installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure enclosure, that is, inside the outer shell.

[0003] To improve ventilation and heat dissipation, existing prefabricated substations typically install ventilation louvers. However, some louvers are fixed structures and cannot be rotated, making it easy for rainwater and dust to enter during heavy rain or sandstorms. While some louvers can be rotated, they need to be adjusted one by one, which is inconvenient due to the large number of louvers. For example, the rain curtain in announcement number CN210985313U requires individual adjustment, which is not convenient.

[0004] Therefore, this utility model designs a dustproof enclosure for transformer substations to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof enclosure for transformer substations to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof transformer substation housing, comprising: a housing, on both sides of which ventilation slots are provided; a plurality of rotating shafts are rotatably installed in the ventilation slots; one end of each rotating shaft is fixedly installed to one end of a louvered plate; a vertical groove is provided on the housing; the other end of each ventilation slot passes through the vertical groove and is fitted with a worm gear; a worm gear meshing with the worm gear is rotatably installed in the vertical groove; a protective component for protecting the worm gear and worm gear is provided in the vertical groove; the louvered plate can be adjusted in angle via the rotating shafts; when encountering heavy rain or sandstorms, the louvered plate rotates downwards and contacts each other, which can relatively seal the ventilation slots, reducing the entry of rainwater or sand into the transformer substation; and through the meshing of the worm gear and worm wheel, the operator can rotate the worm gear to make the plurality of rotating shafts rotate simultaneously, thereby making the plurality of louvered plates rotate synchronously, making adjustment more convenient.

[0007] Preferably, the top of the louvered plate is provided with a placement groove, in which a desiccant can be placed. The desiccant can absorb moisture in the transformer substation and play a role in moisture prevention. When it needs to be replaced, the worm gear is rotated in the reverse direction to make the louvered plate rotate upward so that the opening of the placement groove faces downward, and the desiccant can fall out.

[0008] Preferably, a rubber sleeve is installed on the lower side of the outer wall of the worm gear, which facilitates the rotation of the worm gear by the operator.

[0009] Preferably, the protective component includes a sliding groove formed on the housing and communicating with one end of the vertical groove. A protective plate is slidably installed in the sliding groove. When the worm gear does not need to be rotated, the protective plate slides out of the sliding groove to protect the vertical groove and reduce dust accumulation on the worm gear and worm wheel. The protective plate is provided with a pull groove for easy pulling.

[0010] Preferably, one end of the protective plate and the ventilation groove are connected by a spring, and the restoring force of the spring allows the protective plate to seal the vertical groove more stably.

[0011] Preferably, a fixing block is installed on the housing. The fixing block is located at one end below the vertical groove and close to the slide groove. A limiting plate is slidably installed on the fixing block. When the protective plate is pulled into the slide groove, the limiting plate is pushed inward. The limiting plate limits the protective plate, preventing it from popping out, which facilitates the operator to rotate the worm gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model rotates the worm gear, which drives the rotating shaft to rotate, thus rotating the louvers. During heavy rain or sandstorms, the louvers rotate downwards, relatively sealing the ventilation slots and reducing the entry of rainwater or sand into the transformer. Furthermore, through the meshing of the worm gear and worm wheel, several rotating shafts rotate simultaneously, causing the louvers to rotate synchronously, eliminating the need for individual adjustments and making it more convenient.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 An embodiment of this utility model provides a dustproof transformer substation housing, comprising: a housing 1, ventilation slots 2 on both sides of the housing 1, a plurality of rotating shafts 3 rotatably installed in the ventilation slots 2, one end of the rotating shafts 3 and one end of the louvers 4 being fixedly installed, a vertical slot 5 on the housing 1, the other end of the ventilation slot 2 passing through the vertical slot 5 and having a worm gear 6 installed therein, a worm 7 meshing with the worm gear 6 being rotatably installed in the vertical slot 5, and a protective component 9 for protecting the worm gear 6 and the worm 7 being provided in the vertical slot 5.

[0021] Please see Figure 1-3 In this embodiment: the top of the louvered panel 4 is provided with a placement groove 401.

[0022] Please see Figure 1-3 In this embodiment: a rubber sleeve 8 is installed on the lower side of the outer wall of the worm 7, which makes it more comfortable for the operator to rotate the worm 7.

[0023] Please see Figure 1-3 In this embodiment: the protective component 9 includes a slide groove 901, which is formed on the housing 1 and communicates with one end of the vertical groove 5. A protective plate 902 is slidably installed in the slide groove 901, which seals the vertical groove 5 and can reduce dust or rainwater from adhering to the worm 7 and worm wheel 6.

[0024] Please see Figure 1-3 In this embodiment: one end of the protective plate 902 and the ventilation groove 2 are connected by a spring 903. The restoring force of the spring 903 causes the protective plate 902 to slide outward from the slide groove 901, so that the protective plate 902 can seal the vertical groove 5 more stably.

[0025] Please see Figure 1-3 In this embodiment: a fixing block 904 is installed on the housing 1. The fixing block 904 is located below the vertical groove 5 and near the end of the sliding groove 901. A limit plate 905 is slidably installed on the fixing block 904.

[0026] Working principle: When encountering heavy rain or sandstorms, the rubber sleeve 8 can be rotated, causing the worm gear 7 to rotate, which in turn drives the worm wheel 6 to rotate. The worm wheel 6 drives the rotating shaft 3 to rotate, causing the louvers 4 to rotate downwards. After several louvers 4 rotate downwards and come into contact with each other, the ventilation slot 2 is relatively sealed, which can reduce the entry of rainwater or sand into the housing 1. The protective plate 902 seals the vertical slot 5, which can reduce the entry of rainwater or sand into the vertical slot 5. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
