Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinets, and more specifically, to an outdoor ring network cabinet. Background Technology

[0002] Commonly used ring main units are usually installed outdoors. The ring main unit generally contains electrical components that distribute power, control power, protect power, and monitor and measure power. It needs to provide good ventilation and heat dissipation. Therefore, there are usually a lot of exhaust vents on the cabinet. However, in southern regions, frequent rainfall and high humidity can cause moisture to enter the cabinet through the vents, affecting the operation of internal electrical components and even causing damage. Current solutions involve installing high-polymer moisture-proof cotton inside the cabinet, along with heating and ventilation equipment, which provides good moisture and condensation prevention. However, this method, especially at the gas inlet, lacks an initial barrier, allowing moisture to easily penetrate deep into the cabinet with the airflow, increasing the probability of moisture contacting electrical components. This presents significant drawbacks and room for improvement. Utility Model Content

The top of the filter component is rotatably mounted on the inner wall of the support frame. The filter element of the filter component is a flexible structure, and the bottom end of the filter element is supported inside the support frame by a first support bar. The filter component is supported and unfolded by an elastic element, causing the filter element to unfold and tighten. When the water absorption of the filter component increases, the filter component overcomes the elastic force of the elastic element and gradually swings down to reduce the ventilation range. The baffle is installed at the outer port of the support frame and has multiple air inlets corresponding to the multiple filter components. The inner wall is provided with a limiting strip for limiting the airflow direction.

[0006] In a preferred embodiment of this invention, the filtration assembly includes a window leaf, a first rotating shaft, a filter element, a first support bar, and an absorbent cotton block.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 4As shown in the figure, a specific embodiment of this utility model discloses an outdoor ring mesh cabinet, including a cabinet 100, a cabinet door installed on one side wall of the cabinet; an exhaust window installed on the top surface of the cabinet; an opening 110 is provided at the top of the side wall of the cabinet 100, and a flow-limiting structure 200 is installed at the opening 110; the flow-limiting structure 200 is provided with multiple filter components 210, and the airflow entering from the outside must pass through the filter components before entering the cabinet; the filter components 210 can absorb the moisture in the airflow, and when the amount of absorbed moisture reaches a preset range, they deform and reduce the ventilation range to slow down the airflow entering.

[0017] The aforementioned outdoor ring network cabinet has a flow-limiting structure installed at the opening. The airflow entering the cabinet is filtered by the filter components on the flow-limiting structure to prevent the entry of impurities and debris, and also to absorb the moisture. This effectively prevents moisture from quickly entering the depths of the cabinet and affecting the electrical components. Furthermore, when the amount of moisture absorbed by the filter components reaches a preset range, it deforms and reduces the ventilation range to slow down the airflow, further preventing airflow mixed with moisture from entering the cabinet.

[0018] Furthermore, such as Figures 3 to 5 As shown, the flow-limiting structure 200 includes a support frame 220, a baffle 230, and multiple filter components 210. The support frame 220 is installed at the opening 110. The top of the filter component 210 is rotatably mounted on the inner wall of the support frame 220, giving it a base condition for swinging. The filter element 211 of the filter component 210 is a flexible structure, and the bottom end of the filter element 211 is supported inside the support frame 220 by the first support bar 212. The filter component 210 is supported and unfolded by the elastic element 240, so that the filter element 211 unfolds and tightens. The filter element is the part through which gas passes, and it can block impurities and absorb water. Furthermore, the elastic element is used as the elastic force for unfolding and resetting, while the filter element limits the limit position of the unfolding of the filter component, keeping it at a suitable unfolding angle, which facilitates subsequent deformation adjustment. When the water absorption of the filter assembly increases, the filter assembly overcomes the elastic force of the elastic element and gradually swings down to reduce the ventilation range, which naturally restricts the entry of external airflow and has a slowing effect; the baffle 230 is installed at the outer port of the support frame 220 and has multiple air inlets 231 corresponding to multiple filter assemblies 210. The inner wall is provided with a limiting strip to limit the airflow direction, further limiting the airflow channel and ensuring that the airflow must pass through the filter before entering the cabinet. The filter element is a filter cloth structure, which can not only allow airflow to pass through, but also achieve the filtering effect and adsorb moisture.

[0019] Furthermore, a flange is fixed to the outer wall of the support frame near the cabinet, with a round hole at the flange and a threaded hole on the outer side of the open opening. The flange is fixed to the cabinet with screws. The internal shape of the baffle matches the shape of the outer wall of the support frame. Corresponding holes are provided on both sides of the baffle and the support frame. The baffle covers the outside of the support frame and is fixedly connected with screws. The modular structure facilitates the processing and production of each structural component and makes it easy to replace parts. The current limiting structure can also be used as a module and can be selected according to usage requirements.

[0020] Furthermore, the filter assembly 210 includes a window leaf 213, a first rotating shaft 214, a filter element 211, a first support bar 212, and an absorbent cotton block 215; the top of the window leaf 213 is mounted between two opposite side walls of the support frame 220 via the first rotating shaft 214; the filter element 211 is pasted and fixed to the wall surface of the window leaf 213 near the baffle, the bottom of the filter element extends downward beyond the bottom surface of the window leaf, and the bottom of the filter element 211 is pasted and fixed to the first support bar 212, which is mounted between two opposite side walls of the support frame; Absorbent cotton block 215 is adhered to filter element 211 and connected to the bottom of the window slats. The filter element provides a sufficiently large coverage area to ensure that airflow must pass through the filter element before entering. The absorbent cotton block, adhered to the filter element, facilitates the adsorption of moisture and the transfer of liquid, allowing liquid to collect on the more absorbent cotton block. Furthermore, the absorbent cotton block is located at the bottom of the window slats, lowering the center of gravity when water is absorbed, thus better reducing the ventilation space. It should be noted that the absorbent cotton block is made of high-polymer moisture-proof cotton material, providing excellent water absorption performance, large water absorption capacity, and no water dripping after saturation. Moreover, it can be reused after drying and is currently a commonly used material for preventing condensation inside cabinets, which can be purchased and used on the market. Furthermore, the opposite side walls of the support frame are provided with a plurality of through holes for the first rotating shaft and the first frame bar to pass through. The positions of the through holes all fall within the coverage area of ​​the baffle, which can limit the first rotating shaft and the first frame bar to prevent them from detaching. Furthermore, the bottom of the window leaf 213 is provided with a strip-shaped opening, the top of which extends to the middle of the window leaf, and the bottom of which extends through the bottom surface of the window leaf; the filter element 211 completely covers the strip-shaped opening; the absorbent cotton block 215 is pasted on the wall surface of the filter element 211 away from the baffle, and is fitted and filled at the strip-shaped opening; this can reduce the weight of the window leaf, facilitate the push-opening of the elastic element, and eliminate the need for a high-strength elastic element; it also facilitates expanding the range of the absorbent cotton block, so that the weight of the absorbent cotton block after absorbing water can better overcome the elasticity of the elastic element, thereby achieving the effect of reducing the ventilation range and slowing down the airflow.

[0021] Furthermore, the inner wall of the cover 230 is fixedly provided with support strips 232 corresponding to multiple window leaflets. The support strips 232 are provided with multiple slots 233 evenly spaced along the length direction. The elastic element 240 is a spring sheet structure, with one end locked in the slot 233 and the other end abutting against the window leaflet 213, providing the window leaflet with an outward pushing force. The elastic element is provided with an installation part, which can be pre-assembled on the cover. When the cover is installed in place, it means that the elastic element is installed in place, which facilitates actual assembly and use.

[0022] Furthermore, the top of the window leaf 213 has an arc-shaped structure, and the outer wall of the top of the uppermost window leaf slides against the inner wall of the support frame. The inner wall of the baffle 230 is fixedly provided with multiple first limiting strips 234 and second limiting strips 235; the first limiting strips 234 are provided corresponding to the top of the remaining window leaf 213, and the first limiting strip has a first groove, and the top of the window leaf slides against the inner wall of the first groove; the second limiting strips 235 are provided corresponding to the first frame strip 212, and the second limiting strip has a second groove, the filter element covers the first frame strip and abuts against the inner wall of the second groove; this structural design can further limit the flow of air, block the gap, and make the airflow must pass through the filter element before entering the cabinet; the second limiting strip can also clamp and fix the mating part of the filter element and the first frame strip to further prevent loosening.

[0023] Furthermore, baffles 120 are fixedly provided on the inner sides of both ends of the open opening 110, and the ends of the window leaf 213 and the filter element 211 slide against the inner wall of the baffle 120; the bottom end of the window leaf in the outward unfolded state does not exceed the edge of the baffle, which can prevent airflow from entering the cabinet from both ends and ensure that the airflow passes through the filter element.

[0024] Furthermore, the air inlet 231 is tilted downwards at the end away from the support frame to prevent rainwater from entering, avoid the filter components from absorbing water too quickly and reducing the ventilation space, and maintain the required ventilation effect.

[0025] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model.
