Description

Technical Field

[0001] This utility model relates to the field of ring main unit technology, specifically to a rainproof ring main unit. Background Technology

[0002] As an important power distribution device in the power system, the internal electrical components of the ring main unit continuously generate heat during operation. If the heat cannot be dissipated in time, the temperature inside the cabinet will rise, affecting the working stability and service life of the electrical components, and in severe cases, even causing equipment failure. Therefore, heat dissipation holes need to be set on the side wall of the ring main unit cabinet to achieve air circulation inside and outside the cabinet and ensure heat dissipation effect.

[0003] However, the installation of ventilation holes also brings the problem of rainwater intrusion. In rainy weather, rainwater can easily enter the cabinet directly through the ventilation holes, and may cause short circuits, leakage and other safety hazards after contacting electrical components, disrupting the normal operation of the ring main unit and threatening the reliability of the power distribution system.

[0004] To address this issue, existing technologies employ some rainproof measures, such as adding simple rain shields or filters to the ventilation holes. However, these measures often fail to simultaneously guarantee rainproof performance and good ventilation and heat dissipation. Either the rainproof structure obstructs the heat dissipation, leading to reduced efficiency, or the ventilation requirements result in insufficient rainproofing, failing to effectively meet the safe operation requirements of ring main units under complex weather conditions. Therefore, there is an urgent need for a ring main unit structural design that can balance rainproof and heat dissipation performance to overcome the shortcomings of existing technologies. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a rainproof ring cage.

[0006] The technical solution adopted by this utility model is: a rainproof ring mesh box, including a cabinet shell, wherein heat dissipation holes are provided on the side wall of the cabinet shell, and further comprising: A rain cover, the lower half of which covers the heat dissipation holes, and the lower half of the rain cover is provided with a first ventilation hole adapted to the heat dissipation holes. The bottom wall of the rain cover is also provided with a drain outlet. The movable baffle is slidably disposed between the rain cover and the outer wall of the cabinet shell. At least two bottom-opening partition grooves are provided in the movable baffle. The lower half of the movable baffle is provided with second ventilation holes on both sides that connect to the partition grooves. The upper plate of the partition plate between the partition grooves is provided with a through third ventilation hole, and the third ventilation hole located on the upper plate does not overlap with the second ventilation hole in the lower half. An actuator is connected to a movable baffle to drive the movable baffle to slide up and down inside the rain cover.

[0007] Furthermore, the actuator is an electric cylinder, the output end of which extends into the rain cover and connects to the movable baffle.

[0008] Furthermore, the inner walls on both sides of the rain cover are provided with sliding grooves that are adapted to the movable baffle.

[0009] Furthermore, sliding holes are provided on both sides of the drain outlet, and a sliding rod is slidably connected in the sliding holes. A trigger end is provided at the upper end of the sliding rod, and a sealing plate is connected at the lower end of the sliding rod. A plug adapted to the drain outlet is provided on the sealing plate. A closing spring is provided between the trigger end and the bottom wall of the rain cover. During the process of the movable baffle sliding down to the bottom, the movable baffle can abut against the trigger end and disengage the plug from the drain outlet to open the drain outlet. The closing spring has an elastic force to pull the plug back and close the drain outlet.

[0010] Furthermore, the outer ring of the plug is provided with at least one sealing ring.

[0011] Furthermore, it also includes a rain sensor and a controller, the controller being connected to the rain sensor and the actuator, respectively.

[0012] The beneficial effects of this utility model are: 1. Balancing Rain Protection and Ventilation: This application utilizes a collaborative design of a rain cover and a movable baffle. During rainy weather, the actuator drives the movable baffle downwards to face the heat dissipation holes. Rainwater is effectively blocked by the movable baffle and the partition plate, preventing it from directly entering the cabinet through the heat dissipation holes. Simultaneously, the interconnected structure of the first ventilation hole, the partition groove, the second ventilation hole, and the third ventilation hole ensures air circulation between the inside and outside of the cabinet while preventing rainwater intrusion. This completely resolves the contradiction in existing technologies where "rain protection affects heat dissipation, and heat dissipation weakens rain protection." It effectively prevents short circuits, leakage, and other safety hazards caused by rainwater contacting electrical components, significantly improving the operational safety of the ring main unit during rainy weather and ensuring the reliability of the power distribution system.

[0013] 2. Adaptive adjustment and optimized heat dissipation efficiency: In dry weather, the actuator can move the movable baffle upward so that the heat dissipation holes are directly aligned with the first ventilation hole on the rain cover. At this time, the air circulation path inside and outside the cabinet is shorter and the resistance is lower, which can maximize the heat dissipation efficiency and quickly dissipate the heat generated by the operation of the electrical components inside the cabinet. This avoids the cabinet temperature from being too high and affecting the working stability and service life of the components. It achieves adaptive adjustment of "rain protection in rainy weather and efficient heat dissipation in sunny weather", which can fully adapt to the operating needs under different weather conditions.

[0014] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0023] 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.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] This utility model provides a rainproof ring mesh box.

[0026] In this embodiment, refer to Figure 1-6 The rainproof ring cage includes a cabinet shell 1, on which heat dissipation holes 2 are provided on the side wall, and also includes: Rain cover 3, the lower half of the rain cover 3 covers the heat dissipation holes, and the lower half of the rain cover is provided with a first ventilation hole 4 that matches the heat dissipation holes. The bottom wall of the rain cover is also provided with a drain outlet 5. The movable baffle 6 is slidably disposed between the rain cover and the outer wall of the cabinet shell. At least two bottom-opening partition grooves 7 are provided in the movable baffle at intervals. The lower half of the movable baffle is provided with second ventilation holes 8 that connect to the partition grooves on both sides. The upper plate of the partition plate 18 between the partition grooves is provided with a through third ventilation hole 9, and the third ventilation hole located on the upper plate does not overlap with the second ventilation hole in the lower half. The actuator 19 is connected to the movable baffle and is used to drive the movable baffle to slide up and down inside the rain cover.

[0027] In the above technical solution, the lower half of the rain cover covers the heat dissipation holes of the cabinet shell, and its first ventilation hole is adapted to the heat dissipation holes to achieve heat dissipation and ventilation. The bottom wall drain is used to drain rainwater blocked by the baffle and partition. The movable baffle is slidably set between the rain cover and the cabinet shell. The internal partition groove, the second ventilation holes on both sides (located in the lower half), and the third ventilation hole on the upper part of the partition (which does not overlap with the second ventilation hole) form a staggered ventilation path. The actuator drives the movable baffle to slide up and down, switching between different working states: when it rains, the baffle moves down, allowing the heat dissipation holes to ventilate through the detour path of the first ventilation hole, the second ventilation hole, the partition groove, and the third ventilation hole, using the baffle and partition to block rainwater; when there is no rain, the baffle moves up, allowing the heat dissipation holes to be directly aligned with the first ventilation hole, forming a short path ventilation.

[0028] The above solution breaks the contradiction of existing technology that "rain protection and heat dissipation cannot be achieved at the same time". In rainy weather, air circulation can be ensured through special ventilation paths, while preventing rainwater from directly entering the heat dissipation holes, avoiding short circuits and leakage of electrical components, and improving the safety of ring main unit operation in rainy weather.

[0029] Specifically, the actuator is an electric cylinder, whose output end extends into the rain cover and connects to the movable baffle.

[0030] In this embodiment, the actuator is an electric cylinder. The extension and retraction of the electric cylinder precisely controls the up and down sliding stroke of the movable baffle inside the rain cover, realizing a stable switch between the two states of "downward rain protection" and "upward heat dissipation" of the baffle, replacing manual or other unstable driving methods.

[0031] Specifically, the inner walls on both sides of the rain cover are provided with sliding grooves 10 that are adapted to the movable baffle.

[0032] In this embodiment, sliding grooves adapted to the movable baffles are provided on the inner walls of both sides of the rain cover. The two sides of the movable baffles are embedded in the sliding grooves, so that the baffles move along the track of the sliding grooves when sliding up and down, limiting the lateral displacement of the baffles and ensuring that the baffles always maintain a corresponding positional relationship with the heat dissipation holes and ventilation holes.

[0033] Specifically, sliding holes 11 are provided on both sides of the drain outlet, and sliding rods 12 are slidably connected in the sliding holes. A trigger end 13 is provided at the upper end of the sliding rod 12, and a sealing plate 14 is connected at the lower end of the sliding rod. A plug 15 adapted to the drain outlet is provided on the sealing plate. A closing spring 16 is provided between the trigger end and the bottom wall of the rain cover. During the process of the movable baffle sliding down to the bottom, the movable baffle can abut against the trigger end and disengage the plug from the drain outlet to open the drain outlet. The closing spring has the elastic force to pull the plug back and close the drain outlet.

[0034] In this embodiment, sliding holes are provided on both sides of the drain outlet, and a sliding rod is slidably connected in the sliding holes. A sealing spring is provided between the upper trigger end and the bottom wall of the rain cover, and the plug of the lower sealing plate is adapted to the drain outlet. When it rains, the movable baffle slides down to the bottom, squeezing the trigger end to make the sliding rod go down, driving the plug to disengage from the drain outlet and opening the drainage channel. When there is no rain, the baffle goes up, the sealing spring resets and pulls the sliding rod up, and the plug re-seals the drain outlet, realizing the automatic control of the drain outlet "opening in rainy weather and closing when there is no rain".

[0035] Specifically, the outer ring of the plug is provided with at least one sealing ring 17.

[0036] In this embodiment, at least one sealing ring is provided on the outer ring of the plug. The sealing ring is made of an elastic material (such as rubber). When the plug blocks the drain outlet, the sealing ring fits tightly against the inner wall of the drain outlet, filling the gap between the plug and the drain outlet, enhancing the sealing performance, and preventing external debris or a small amount of water vapor from entering the rain cover through the gap when there is no rain.

[0037] Specifically, it also includes a rain sensor and a controller, the controller being connected to the rain sensor and the actuator respectively.

[0038] In this embodiment, the rain sensor detects whether it is raining in real time and transmits the detection signal (e.g., outputting a high level when it is raining and a low level when it is not raining) to the controller. After receiving the signal, the controller controls the actuator to act according to the preset program: when it is raining, the actuator drives the movable baffle downward to enter the rainproof state; when it is not raining, the actuator drives the movable baffle upward to enter the high-efficiency heat dissipation state, realizing the fully automatic switching between rainproof and heat dissipation.

[0039] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
