[0001] The utility model relates to the technical field of ring main units, in particular to a rainproof and ventilation structure for an outdoor ring main unit. Background Art

[0002] A ring main unit is a device used in a distribution network, mainly for switch operations and power distribution in a power system. It is usually installed outdoors and can withstand various harsh climate conditions. The outdoor ring main unit has a wide range of applications, mainly including power distribution systems in urban distribution networks, industrial park power distribution, railways, airports and other places.

[0003] At present, in the actual application of outdoor ring main units, a variety of electrical switches such as voltage and current transformers and relay protectors generally need to be installed inside. In order to ensure that the heat inside the ring main unit can be normally discharged to the outside, ventilation windows are mostly provided on both sides of the ring main unit body. When heavy rain occurs, rainwater from the outside easily sneaks into the ring main unit body through the ventilation window frames, which may cause the internal electrical components to get damp. Therefore, it is necessary to design a rainproof and ventilation structure for an outdoor ring main unit to solve the above problems. Summary of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract and the title of the specification of this application, to avoid obscuring the purpose of this part, the abstract and the title. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0005] In view of the above problems existing in the existing rainproof and ventilation structure for an outdoor ring main unit, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a rainproof and ventilation structure for an outdoor ring main unit, which is suitable for solving the problem that when heavy rain occurs, rainwater from the outside easily sneaks into the ring main unit body through the ventilation window frames, resulting in dampness of the internal electrical components.

[0007] To solve the above technical problems, the present utility model provides the following technical solution: A rainproof and ventilation structure for an outdoor ring main unit, comprising:

[0008] A ring main unit body unit, which includes a ring main unit body and ventilation window frames opened on both sides of the ring main unit body. A plurality of groups of evenly distributed rainproof leaves are rotatably connected inside the ventilation window frames;

[0009] Rainproof ventilation unit, which includes a plurality of rotating rods rotatably connected within the ventilation window frame. Each rainproof leaf is fixedly sleeved on the rotating rod, and one end of the rotating rod extending outwards through the ventilation window frame is fixedly connected with a circular gear. On both sides of the inner cavity of the ring main cabinet, there are vertically sliding racks meshing with a plurality of circular gears. On the inner side wall of the ring main cabinet, there is a fixedly connected fixing ear. The upper side wall of the fixing ear and the lower side wall of the rack are connected through a telescopic column, and a return spring is sleeved on the telescopic column. The top end of the rack is fixedly connected with a water storage bucket through a lifting rod, and the lower end of the side wall of the water storage bucket is fixedly communicated with a drain pipe.

[0010] As a preferred solution of the rainproof ventilation structure of an outdoor ring main cabinet described in the present utility model, wherein: the lower end of the ring main cabinet is fixedly connected with a waterproof platform, and the top end of the ring main cabinet is fixedly connected with a rainproof cover.

[0011] As a preferred solution of the rainproof ventilation structure of an outdoor ring main cabinet described in the present utility model, wherein: at the upper opening of each water storage bucket, there is a fixedly connected water storage cover, and the water storage cover is arranged in a horn shape with a large upper opening and a small lower opening.

[0012] As a preferred solution of the rainproof ventilation structure of an outdoor ring main cabinet described in the present utility model, wherein: on the lower inner side wall of each ventilation window frame, there is a fixedly connected water blocking strip, and the water blocking strip is arranged close to the center of the ring main cabinet.

[0013] As a preferred solution of the rainproof ventilation structure of an outdoor ring main cabinet described in the present utility model, wherein: on both inner side walls of the ring main cabinet, there are fixedly connected guide rails, and the rack is vertically slidably connected with the guide rails.

[0014] As a preferred solution of the rainproof ventilation structure of an outdoor ring main cabinet described in the present utility model, wherein: each circular gear and rack are made of manganese steel, and the surfaces of the rack and the circular gear are provided with uniformly distributed anti-slip lines.

[0015] The beneficial effects of the present utility model: When heavy rain occurs, the rainwater is directly guided by the water storage cover and falls into the water storage bucket. At this time, the drainage rate of the drain pipe is much smaller than the water demand rate of the water storage bucket, and the water volume in the water storage bucket increases. It will drive the rack to move downward through the lifting rod. The circular gear meshing with the rack drives the rainproof leaf to rotate relative to the ventilation window frame through the rotating rod, and the adjacent two rainproof leaves are pressed against each other, which can timely close the ventilation window frame, effectively solving the defect that the rainwater outside is likely to pour into the ring main cabinet during rainfall, causing the internal electrical appliances to get damp. When the rain intensity weakens or the rain stops, at this time, the drainage rate of the drain pipe is greater than the water storage rate of the water storage bucket, and the water volume in the water storage bucket continuously decreases. The originally compressed return spring pushes the rack upwards, and the originally closed rainproof leaves unfold, and the ventilation window frame opens, ensuring that the heat in the ring main cabinet can be normally discharged through the ventilation window frame.

[0025] Embodiment

[0026] Refer to Figures 1 - 3 , which is an embodiment of the present utility model, and provides a rainproof and ventilation structure for an outdoor ring main unit, including: a ring main unit body unit 100 and a rainproof and ventilation unit 200.

[0027] Among them, the ring main unit body unit 100 includes a ring main unit body 101 and ventilation window frames 104 opened on both sides of the ring main unit body 101. A water blocking strip 208 is fixedly connected to the inner wall of the lower side of each ventilation window frame 104, and the water blocking strip 208 is arranged close to the center of the ring main unit body 101. Through the arrangement of the water blocking strip 208, the defect that rainwater easily enters the ring main unit body 101 through the gap between the inner wall of the lower side of the ventilation window frame 104 and the lowermost rainproof leaf 105, causing the internal electrical components to be affected by moisture, is effectively solved. A plurality of groups of evenly distributed rainproof leaves 105 are rotatably connected in the ventilation window frame 104. A waterproof platform 102 is fixedly connected to the lower end of the ring main unit body 101, and a rainproof cover 103 is fixedly connected to the top end of the ring main unit body 101. Through the arrangement of the waterproof platform 102, the defect that accumulated rainwater on the ground easily enters the ring main unit body 101 is effectively solved. The arrangement of the rainproof cover 103 can provide rainproof and moisture-proof protection for the ring main unit body 101 from the upper end;

[0028] Secondly, the rainproof and ventilation unit 200 includes a plurality of rotating rods 201 rotatably connected within the ventilation window frame 104. Each rainproof leaf 105 is fixedly sleeved on the rotating rod 201, and one end of the rotating rod 201 extending outward through the ventilation window frame 104 is fixedly connected with a circular gear 202. On both sides of the inner cavity of the ring network cabinet 101, there are vertically sliding racks 203 meshing with the plurality of circular gears 202. Each circular gear 202 and rack 203 are made of manganese steel, and the surfaces of the rack 203 and circular gear 202 are provided with evenly distributed anti-slip lines. The circular gears 202 and racks 203 made of manganese steel have good wear resistance and extrusion resistance, extending the service life of both. The setting of the anti-slip lines improves the meshing stability between the circular gear 202 and the rack 203. On both inner walls of the ring network cabinet 101, there are fixedly connected guide rails 204, and the rack 203 is vertically slidably connected with the guide rails 204. Through the cooperation of the guide rails 204 and the rack 203, the stability of the rack 203 rising and falling relative to the ring network cabinet 101 is improved. On the inner side wall of the ring network cabinet 101, there is fixedly connected a fixed ear 205. The upper side wall of the fixed ear 205 is connected with the lower side wall of the rack 203 through a telescopic column 206. A return spring 207 is sleeved on the telescopic column 206. The top end of the rack 203 is fixedly connected with a water storage bucket 210 through a lifting rod 209. The lower end of the side wall of the water storage bucket 210 is fixedly communicated with a drain pipe 212. At the upper opening of each water storage bucket 210, there is fixedly connected a water storage cover 211, and the water storage cover 211 is arranged in a trumpet shape with a large upper opening and a small lower opening. The setting of the water storage cover 211 improves the rate of the water storage bucket 210 receiving rainwater.

[0029] During use, when there is heavy rainfall, the rainwater is directly guided by the water storage cover 211 and falls into the water storage bucket 210. At this time, the drainage rate of the drain pipe 212 is much smaller than the water demand rate of the water storage bucket 210, and the water volume in the water storage bucket 210 increases. It will drive the rack 203 to move downward through the lifting rod 209. The circular gear 202 meshing with the rack 203 drives the rainproof leaf 105 to rotate relative to the ventilation window frame 104 through the rotating rod 201, and the adjacent two rainproof leaves 105 are pressed against each other, which can timely close the ventilation window frame 104, effectively solving the defect that the rainwater from the outside is likely to pour into the ring network cabinet 101 during rainfall, causing the internal electrical appliances to get damp. When the rain intensity weakens or the rain stops, at this time, the drainage rate of the drain pipe 212 is greater than the water storage rate of the water storage bucket 210, and the water volume in the water storage bucket 210 continuously decreases. The originally compressed return spring 207 pushes the rack 203 upward, and the originally closed rainproof leaves 105 unfold, and the ventilation window frame 104 opens, ensuring that the heat in the ring network cabinet 101 can be normally discharged through the ventilation window frame 104.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
