Description

Technical Field

[0001] This invention relates to the field of smart grid terminal equipment, and more particularly to a non-standard power distribution cabinet with anti-condensation temperature control and dehumidification. Background Technology

[0002] With the deepening of smart grid construction, a large number of terminal equipment such as distribution automation, electricity consumption information collection, and intelligent monitoring are deployed in outdoor environments, placing higher demands on the adaptability and reliability of distribution cabinets. Non-standard distribution cabinets, customized according to customer site requirements, are widely used in outdoor facilities and various distribution terminal nodes of smart grids. Because the electrical components inside the distribution cabinet generate heat during operation, and the outdoor environment has temperature differences and humidity variations, the hot and humid air inside the cabinet easily condenses on the surface of the components or the inner wall of the cabinet, a phenomenon known as "condensation." Condensation can lead to serious problems such as decreased insulation performance, corrosion of metal parts, and electrical short circuits. Especially in remote terminals and unattended sites of smart grids, a fault caused by condensation will directly affect the reliability of power supply and the system's self-healing ability. Therefore, existing non-standard distribution cabinets are usually equipped with dehumidifiers, heaters, or temperature and humidity controllers to suppress condensation by reducing the humidity or increasing the temperature inside the cabinet.

[0003] Commonly, heat dissipation vents are provided on the side walls of the cabinet to expel heat from inside. To waterproof these vents, a protruding waterproof cover is usually integrally connected to the cabinet at the corresponding location, with its opening facing downwards to prevent rainwater from directly entering. However, in practical applications, the following drawbacks exist: the vent openings are forced to face downwards, while hot air rises. The hot air inside the cabinet must first flow downwards and then upwards again to escape, resulting in a tortuous flow path and increased resistance, significantly reducing heat dissipation efficiency. For non-standard distribution cabinets in smart grids that integrate communication modules, smart sensors, and other heat-generating components, this insufficient heat dissipation efficiency further exacerbates the risk of temperature rise and condensation inside the cabinet, making it difficult to meet the high reliability and low maintenance requirements of modern power systems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a new anti-condensation temperature-controlled dehumidification non-standard power distribution cabinet, thereby solving the above-mentioned technical problems.

[0005] The non-standard temperature-controlled and dehumidifying power distribution cabinet with anti-condensation function provided by this invention includes a power distribution cabinet body, a heat dissipation vent on the side of the power distribution cabinet body, and further includes: A rotating waterproof component is installed on the side of the power distribution cabinet body at the position corresponding to the heat dissipation vent. It includes a mounting bracket fixed on the power distribution cabinet body and a rain cover rotatably connected to the mounting bracket. The rain cover has a vertical state with the heat dissipation vent open and an inclined state with the heat dissipation vent closed. An automatic push-pull assembly, which is connected between the mounting bracket and the rain cover, includes water-absorbing and expandable rubber that can expand and contract axially when wet, and is used to automatically drive the rain cover to switch between a vertical and tilted state according to weather conditions.

[0006] Preferably, the mounting bracket is in the shape of an inverted U and is fixed to the main body of the distribution cabinet with screws. Its length is greater than the length of the heat dissipation vent, so that the heat dissipation vent can be completely covered by the tilted rain cover.

[0007] Preferably, a first leg is welded onto the mounting frame, and a second leg is welded onto the rain cover, with the second leg being rotatably connected to the first leg via a pivot.

[0008] Preferably, a torsion spring is sleeved on the rotating shaft, with one end of the torsion spring acting on the first leg and the other end acting on the second leg, so as to make the rain cover have a tendency to rotate from an inclined state to a vertical state.

[0009] Preferably, a water-retaining eave is welded onto the mounting frame, and the water-retaining eave is located near the highest point of the mounting frame, with an extension length greater than the thickness of the rain cover.

[0010] Preferably, a third leg is welded to the mounting bracket, a fourth leg is welded to the rain cover, and the automatic top-pull assembly is connected between the third leg and the fourth leg and is located inside the rain cover.

[0011] Preferably, the automatic top-pull assembly includes two mounting cylinders and a water-absorbing and expanding rubber fixed between the two mounting cylinders. The other end of each of the two mounting cylinders is provided with a ring seat, and the two ring seats are respectively rotatably connected to the third and fourth legs.

[0012] Preferably, a ring plate is integrally connected to each of the two ring seats, and a protective component is provided between the two ring plates; The protective component includes a telescopic silicone tube, the two ends of which are fixed to two ring plates and concentrically fitted onto the outside of the water-absorbing and expanding rubber. A guide groove is provided on the top of the telescopic silicone tube, and a water inlet is provided on the guide groove. A drain outlet is provided on the bottom of the telescopic silicone tube.

[0013] Preferably, the telescopic silicone tube has multiple concentrically arranged locking rings embedded inside to limit the radial expansion of the water-absorbing and swelling rubber.

[0014] Preferably, the rain cover is provided with a water collection and supply structure on its exterior; The water supply structure includes an outer cover plate welded to the outer wall of the rain cover, and a water storage tank is formed between the outer cover plate and the rain cover. The depth of the bottom of the water storage tank increases from the center to both ends. A water outlet is provided at the deepest point of the water storage tank on the rain cover, and a water hopper corresponding to the water outlet is provided on the inner side of the rain cover, with the other end of the water hopper extending directly above the guide channel.

[0015] Compared with related technologies, the anti-condensation temperature-controlled and dehumidifying non-standard power distribution cabinet provided by the present invention has the following beneficial effects: In this invention, by incorporating a rotating waterproof component and an automatic top-pull assembly containing water-absorbing and expanding rubber, the rubber contracts during dry, sunny weather, keeping the rain cover vertical with the assistance of a torsion spring. This ensures the heat dissipation vents are fully open, allowing hot air to escape directly upwards, resulting in superior heat dissipation compared to traditional fixed baffle structures. During rainy weather, the rubber automatically absorbs water and expands, automatically driving the rain cover to switch to an inclined position, forming a reliable waterproof eaves. This achieves an adaptive switching between efficient heat dissipation in sunny weather and reliable waterproofing in rainy weather.

[0016] In this invention, a water-collecting and supply structure is installed on the outside of the rain cover. The bottom of the water storage tank is designed with a high center and low ends, so that rainwater automatically collects to the deepest point under gravity. It is then discharged into the guide channel above the telescopic silicone tube through the outlet and drain, and then evenly soaks and expands the rubber through the inlet. After absorbing water, the rubber expands axially, overcoming the torsion spring force and automatically pushing the rain cover to rotate to an inclined state, with the upper end pressing against the side wall of the mounting frame, forming a complete waterproof eaves structure.

[0017] In this invention, a telescopic silicone tube completely seals and covers the water-absorbing and swelling rubber, preventing dust, oil, and other impurities from directly contacting the rubber surface and affecting its water absorption and swelling performance, while also preventing accelerated aging due to ultraviolet radiation. Multiple concentric locking rings embedded inside the telescopic silicone tube, with an inner diameter slightly larger than the rubber's outer diameter, rigidly restrict the rubber's radial expansion, forcing it to prevent free radial expansion when exposed to water. This concentrates the expansion energy into a larger axial elongation, more effectively driving the rain cover's rotation and improving driving efficiency and response reliability.

Therefore, they should not be construed as limitations on this invention.

[0021] In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 10 This patented product can be applied to outdoor power distribution terminals in the field of smart grids, providing them with reliable heat dissipation and anti-condensation protection. This embodiment specifically provides an anti-condensation temperature-controlled dehumidification non-standard power distribution cabinet. The anti-condensation temperature-controlled dehumidification non-standard power distribution cabinet includes a power distribution cabinet body 1. The side of the power distribution cabinet body 1 has multiple heat dissipation vents 2 that are equally spaced vertically to dissipate the heat generated by the internal electrical equipment during operation, ensuring that the temperature inside the cabinet is maintained within a safe range.

[0026] On the side of the main body 1 of the power distribution cabinet, a rotating waterproof component is installed at the position of each heat dissipation vent 2. This component is used to automatically adjust the usage status of the heat dissipation vent 2 according to the weather conditions, so as to achieve adaptive switching between efficient heat dissipation in sunny weather and reliable waterproofing in rainy weather.

[0027] The rotating waterproof component includes a mounting bracket 3 and a rain cover 5. The mounting bracket 3 has an inverted U-shaped structure and is fixed to the outer wall of the distribution cabinet body 1 with screws. The length of the mounting bracket 3 is greater than the length of the heat dissipation vent 2, so that the heat dissipation vent 2 is completely located within the internal area of ​​the mounting bracket 3, ensuring that the rain cover 5 can completely cover the heat dissipation vent 2. A first leg 4 is welded and fixed to one side of the mounting bracket 3, and a corresponding second leg 6 is welded to the rain cover 5. The second leg 6 is rotatably connected to the first leg 4 via a pivot, allowing the rain cover 5 to rotate freely within a certain angle range around the pivot.

[0028] The rain cover 5 has two working states through rotation: vertical and tilted. In the vertical state, the rain cover 5 is parallel to the side wall of the distribution cabinet body 1. At this time, the hot air discharged from the heat dissipation vent 2 can rise directly and be smoothly discharged from the opening between the rain cover 5 and the cabinet body, achieving the best heat dissipation effect. In the tilted state, the upper end of the rain cover 5 abuts against the side wall of the mounting bracket 3. At this time, the rain cover 5 forms an "eaves" structure above the heat dissipation vent 2. Rainwater flows down the outer wall of the rain cover 5 and cannot enter the interior of the heat dissipation vent 2, providing reliable rain protection.

[0029] A torsion spring 7 is also fitted on the rotating shaft. One end of the torsion spring 7 acts on the first leg 4, and the other end acts on the second leg 6. Through the elastic force of the torsion spring 7, the rain cover 5 always has a tendency to rotate from the tilted state to the vertical state, which helps the rain cover 5 to return to the vertical state in sunny weather.

[0030] A water-retaining eave 8 is welded onto the mounting frame 3. This eave 8 is located near the highest point of the mounting frame 3, and its extension length is slightly greater than the thickness of the rain cover 5. When the rain cover 5 is in a vertical position, the eave 8 hardly affects the normal heat dissipation effect of the heat dissipation vent 2, preventing localized heat accumulation. When the rain cover 5 is tilted, the eave 8 is located directly above the contact area between the mounting frame 3 and the rain cover 5, serving to shield and compensate for any small gaps that may form between them. Rainwater channeled along the eave 8 eventually falls onto the outer wall of the rain cover 5, further enhancing the waterproof effect and ensuring that even under strong winds and heavy rain, rainwater cannot seep into the heat dissipation vent 2 through the gaps.

[0031] A third leg 9 and a fourth leg 10 are welded onto the mounting frame 3 and the rain cover 5, respectively. An automatic push-pull assembly is installed between the third leg 9 and the fourth leg 10. This automatic push-pull assembly is located below the rotating connection point of the mounting frame 3 and the rain cover 5, and is used to automatically drive the rain cover 5 to rotate according to the weather conditions (sunny or rainy), so as to achieve unattended adaptive adjustment.

[0032] The automatic lifting assembly includes two mounting cylinders 11, with a cylindrical water-absorbing and expanding rubber 13 fixed between them. Each mounting cylinder 11 has a ring seat 12 fixed to its other end. The ring seats 12 on the two mounting cylinders 11 are rotatably connected to the third leg 9 and the fourth leg 10 via rotating shafts. In sunny weather, the water-absorbing and expanding rubber 13 is in a dry, contracted state, with its axial length at its shortest. At this time, the water-absorbing and expanding rubber 13 itself pulls on the rain cover 5, working in conjunction with the elastic force of the torsion spring 7 to keep the rain cover 5 stably vertical, with the heat dissipation vent 2 fully open for normal heat dissipation. In rainy weather, the water-absorbing and expanding rubber 13 absorbs rainwater and expands axially, increasing its length. This lifts the rain cover 5, causing it to overcome the elastic force of the torsion spring 7 and rotate, switching from a vertical to an inclined state. At this time, the rain cover 5 is in waterproof working mode. This design can automatically and adaptively adjust according to weather conditions without manual intervention, offering high flexibility.

[0033] After the rain stops, the heat generated by the operation of the electrical equipment inside the distribution cabinet 1 will radiate outwards. Some of the heat will be conducted to the water-absorbing and expanding rubber 13, which can accelerate the evaporation of the internal moisture, speed up the drying process, and allow it to return to its contracted state as soon as possible to ensure normal heat dissipation function in subsequent sunny days.

[0034] The entire automatic top-pull assembly is housed inside the rain cover 5 and is protected by it. In sunny weather, the rain cover 5 provides shade for the water-absorbing and swelling rubber 13, reducing its aging rate due to ultraviolet radiation and extending its service life.

[0035] Both mounting cylinders 11 are integrally connected to ring plates 14. A protective component, fitted over the water-absorbing and swelling rubber 13, is disposed between the two ring plates 14 to further reduce the aging rate of the water-absorbing and swelling rubber 13 and provide additional structural protection. The protective component includes a telescopic silicone sleeve 15, with its two ends fixed to the two ring plates 14 respectively. When the water-absorbing and swelling rubber 13 expands and contracts axially, the telescopic silicone sleeve 15 also expands and contracts accordingly, always maintaining a complete coverage of the water-absorbing and swelling rubber 13, achieving effective sealing and protection, and preventing dust, oil, and other impurities from directly contacting the surface of the water-absorbing and swelling rubber 13 and affecting its water absorption and swelling performance.

[0036] An axially extending guide groove 16 is provided above the telescopic silicone tube 15, and a radially penetrating water inlet 17 is provided at the lowest point of the guide groove 16. Multiple drain outlets 18 are provided below the telescopic silicone tube 15. Rainwater can be collected inside the guide groove 16 and flow evenly along the guide groove 16 into each water inlet 17 to fully saturate the water-absorbing and expanding rubber 13. During the subsequent dehydration process, the evaporated water can be smoothly discharged from the water inlets 17 and drain outlets 18; simultaneously, when the water intake is excessive, the excess water can also be discharged promptly from the drain outlets 18, preventing water accumulation from affecting the expansion performance of the water-absorbing and expanding rubber 13 and helping to improve the drying speed.

[0037] Multiple concentrically arranged and axially evenly distributed locking rings 19 are embedded inside the telescopic silicone sleeve 15. The locking rings 19 are non-adjustable rigid structures with an inner diameter slightly larger than the outer diameter of the water-absorbing and swelling rubber 13, used to restrict the radial expansion of the rubber 13. Through the radial constraint of the locking rings 19, the water-absorbing and swelling rubber 13 cannot expand freely radially when exposed to water, thus forcing it to produce a larger axial expansion displacement, more effectively driving the rain cover 5 to rotate, improving driving efficiency and response reliability.

[0038] A water-collecting and supplying structure is also provided on the outside of the rain cover 5 to quickly collect rainwater and guide the collected rainwater to the water-absorbing and expanding rubber 13, so that it can obtain sufficient water to meet its expansion needs at the beginning of rainfall. When the water volume is sufficient, it can also further improve the response speed of the rain cover 5, allowing the rain cover 5 to switch to waterproof mode more quickly. The water-collecting and supplying structure includes an outer cover plate 20 welded and fixed to the outer wall of the rain cover 5, forming a water storage tank 21 between the outer cover plate 20 and the rain cover 5, for quickly collecting rainwater during rainfall. The depth of the inner bottom of the water storage tank 21 is designed to gradually increase from the center to both ends, so that the collected rainwater can automatically gather at the deepest position at both ends under the action of gravity. A water outlet 22 is opened on the rain cover 5 corresponding to the deepest position of the water storage tank 21, and a drain hopper 23 corresponding to the water outlet 22 is also fixed on the inner side of the rain cover 5. The discharge end of the drain hopper 23 extends directly above the telescopic silicone tube 15, so the discharged rainwater can drip directly and collect in the guide channel 16, quickly supplying the water-absorbing and expanding rubber 13 to ensure that it can respond quickly in the early stage of rainfall.

[0039] The specific operating principle of this device is as follows: Step 1: Under clear, dry weather conditions, the water-absorbing and expanding rubber 13 is in a dry, contracted state, with its axial length at its minimum. At this time, the water-absorbing and expanding rubber 13 exerts an inward pulling force on the rain cover 5, which, together with the elastic force of the torsion spring 7, keeps the rain cover 5 in a vertical position. The rain cover 5 is parallel to the side wall of the distribution cabinet body 1, the heat dissipation vent 2 is fully exposed, and hot air can rise directly and be discharged, ensuring unobstructed airflow and placing the distribution cabinet in optimal heat dissipation mode. Simultaneously, the rain cover 5 provides sun protection for the water-absorbing and expanding rubber 13, and the locking ring 19 inside the telescopic silicone sleeve 15 restricts radial expansion but does not affect axial contraction.

[0040] Step Two: When rainfall begins, rainwater falls onto the rain cover 5 and collects in the water storage tank 21. The design of the water storage tank 21, with a high center at the bottom and low ends, allows rainwater to quickly collect to the deepest point and be discharged through the outlet 22 and drain hopper 23 into the guide channel 16 above the telescopic silicone tube 15. Rainwater is evenly distributed along the guide channel 16 and enters the telescopic silicone tube 15 through the inlet 17, soaking the water-absorbing and expanding rubber 13. After absorbing water, the water-absorbing and expanding rubber 13 expands axially, gradually increasing in length, overcoming the elastic force of the torsion spring 7 and pushing the rain cover 5 outward. The rain cover 5 rotates around the pivot, and its upper end gradually approaches the side wall of the mounting bracket 3. When the water-absorbing and expanding rubber 13 is fully expanded, the rain cover 5 is in an inclined state, with its upper end pressing against the mounting bracket 3. The water-blocking eaves 8 cover the tiny gap at the contact point, forming a complete waterproof eaves structure to prevent rainwater from entering the electrical cabinet from the heat dissipation vent 2.

[0041] Third step: After the rainfall stops, no new rainwater is added to the water storage tank 21, and the moisture in the water-absorbing and expanding rubber 13 gradually evaporates. The heat generated by the operation of the electrical components inside the distribution cabinet is radiated outward through the heat dissipation vent 2, accelerating the drying speed of the water-absorbing and expanding rubber 13. After drying, the water-absorbing and expanding rubber 13 gradually shrinks back to its original length, reducing the pushing force on the rain cover 5. Under the restoring elastic force of the torsion spring 7, the rain cover 5 rotates in the opposite direction, automatically returning to a vertical position, the heat dissipation vent 2 reopens fully, and the distribution cabinet returns to its optimal heat dissipation mode.
