[0002] In today's power system, power cabinets are widely used in various places, and many electrical equipment with strict environmental requirements are placed inside them. In humid areas, the air humidity is at a high level all year round, and high-humidity air can easily enter the interior of ordinary power cabinets. Electrical equipment will face many problems if they are in such a humid environment for a long time. For example, high humidity will cause water vapor condensation on the surface of electrical components, which may cause short circuit faults, affect the normal operation of equipment, and even cause equipment damage, increase maintenance costs and power outage risks; Traditional power cabinets often lack effective moisture-proof designs. It is difficult to completely block water vapor by relying solely on simple seals. Once water vapor enters the cabinet, it will condense into water droplets inside the cabinet. These water droplets may drip onto electrical equipment, causing short circuits and other faults, affecting the normal operation of electrical equipment and even causing safety accidents, seriously threatening the stable power supply of the power system.

The air holes are arranged between the water-absorbing sponges. The air holes facilitate the flow of air in the bent ring plate. The air can fully contact the water-absorbing sponge, and the water-absorbing sponge can absorb moisture in the air to play a dehumidifying role and reduce air humidity. Baffles are fixedly installed at both ends of the bent ring plate, and a guide plate is fixedly installed on the inner wall of the bent ring plate. A water outlet pipe is fixedly installed in the middle of the bottom of the bent ring plate. The water outlet pipe runs through the inner cabinet and the outer cabinet and extends to the bottom thereof. The water outlet pipe guides the accumulated water out of the cabinet to prevent moisture accumulation from affecting the dehumidification and the internal environment of the cabinet. A check valve is fixedly installed at the bottom of the water outlet pipe to prevent external water or moisture from flowing back into the cabinet.
[0004] Preferably, a strip air inlet is provided on the outer surface of the outer cabinet body, and the strip air inlet is arranged opposite to the outer cabinet door. The strip air inlet provides an air inlet channel for ventilation inside the cabinet body, and a dustproof net is fixedly installed inside the strip air inlet.

[0005] Preferably, the outer surface of the inner cabinet is provided with a leakage groove, an arc-shaped water guide groove and a water collecting groove, the arc-shaped water guide groove is arranged directly below the leakage groove, the arc-shaped water guide groove is an arc-shaped groove which is low in the middle and high at both ends, and the water collecting groove is arranged in the middle directly below the arc-shaped water guide groove. The number of the leakage grooves is nine, and the nine leakage grooves are evenly distributed inside the bent ring plate, the leakage groove can collect the accumulated water formed after the absorbent sponge is absorbed and saturated, and guide the water to flow downward, the arc-shaped water guide groove guides the water collected by the leakage groove to the water collecting groove, the water guide plate can guide the water in the water collecting groove into the outlet pipe and discharge it out of the cabinet, so as to ensure that the inside of the cabinet is dry, the inside of the leakage groove is equipped with a heat dissipation component, and the bottom of the water collecting groove is fixedly equipped with a water guide plate.
[0006] Preferably, the baffle forms an enclosed space between the bent ring plate, the outer cabinet and the inner cabinet, so that the air can be dehumidified in this limited space to prevent humid air from entering the inner cabinet through the ventilation holes. The water guide plate passes through the water outlet pipe and extends to the interior thereof, so that the water in the water collecting tank can be smoothly introduced into the water outlet pipe and discharged from the cabinet, thereby ensuring that the interior of the cabinet is dry.
[0007] Preferably, the outlet assembly includes an outlet tube, which is fixedly installed at the edge of the bottom of the inner cabinet, and the outlet tube passes through the inner cabinet and the outer cabinet and extends to the bottom thereof. A rubber strip is fixedly connected to the inner wall of the outlet tube. There are several rubber strips, and several of the rubber strips are squeezed and fitted with each other. Multiple rubber strips are squeezed and fitted with each other, which can not only fix the line to prevent it from shaking at will, but also play a certain sealing role to prevent external moisture from entering the inner cabinet from the outlet.
[0008] Preferably, the heat dissipation component includes a fixing groove, which is formed on the inner wall of the inner cabinet. A heat conductive sheet is fixedly installed inside the fixing groove. The fixing groove is used to fix the heat conductive sheet so that it is firmly fixed on the inner wall of the inner cabinet. A heat sink is fixedly connected to one side of the heat conductive sheet. The heat sink penetrates the inner cabinet and the drainage groove and extends to the outside thereof. The heat conductive sheet conducts the heat generated by the electrical equipment inside the inner cabinet to the heat sink. The heat sink can dissipate the heat to the external environment to play a heat dissipation role and ensure that the internal equipment operates at an appropriate temperature. The heat sink can also cooperate with the dehumidification component. When the humid air entering the dehumidification component contacts the heat sink, the water vapor condenses on the surface of the heat sink when it is cold and flows into the drainage groove through the guide sheet.
[0009] Preferably, the guide plate is sealed and fitted with the outer surface of the inner cabinet, and the outer bending part of the bent ring plate is fixedly connected to the inner wall of the outer cabinet, so that the baffle divides the enclosed space formed by the bent ring plate, the outer cabinet and the inner cabinet into multiple layers.

[0011] The present invention provides a moisture-proof power cabinet for humid areas. It has the following beneficial effects: 1. The moisture-proof power cabinet in the humid area has air holes and water-absorbing sponges in the dehumidification component. The air holes are arranged between the water-absorbing sponges, and the air holes are evenly distributed between the water-absorbing sponges, which creates convenient conditions for the flow of air in the bent ring plate. When the external humid air enters the space surrounded by the bent ring plate, the air can flow smoothly in this relatively closed area with the help of the air channel formed by the air holes, thereby ensuring that the air can fully contact the water-absorbing sponge. The water-absorbing sponge can absorb moisture in the air, play a dehumidifying role, and reduce air humidity.
[0012] 2. The moisture-proof power cabinet in the humid area forms an enclosed space between the bent ring plate, the outer cabinet and the inner cabinet through the baffle, the guide plate is sealed and adapted to the outer surface of the inner cabinet, and the outer bending part of the bent ring plate is fixedly connected to the inner wall of the outer cabinet, so that the baffle divides the enclosed space formed by the bent ring plate, the outer cabinet and the inner cabinet into multiple layers. After the humid air enters the enclosed space formed by the bent ring plate and the outer cabinet, the air is filtered layer by layer in the multi-layer space through the air holes and the water-absorbing sponge, thereby efficiently removing moisture from the air.
[0013] 3. The moisture-proof power cabinet in the humid area has a leakage trough, an arc-shaped water guide trough and a water collecting trough. The leakage trough can collect the accumulated water formed after the absorbent sponge is absorbed and saturated, as well as the condensed water on the surface of the heat sink, and guide the water downward. Since the arc-shaped water guide trough is an arc-shaped groove with a low middle and high ends, the arc-shaped water guide trough can guide the water collected by the leakage trough to the water collecting trough in the middle. The water guide plate can guide the water in the water collecting trough into the outlet pipe and discharge it out of the cabinet to ensure that the inside of the cabinet is dry.
[0014] 4. The moisture-proof power cabinet in the humid area can promote the exchange of air inside and outside the inner cabinet and accelerate the air flow through the setting of the blower. When the blower is running, the air inside the inner cabinet is discharged, and the outside air enters from the ventilation holes. A negative pressure is formed in the space between the outer cabinet and the inner cabinet, and the outside air is pressed into the strip air inlet to participate in the dehumidification process. The blower can ensure that the air inside the power cabinet is always in a dynamic update state, avoiding the problem of humid air accumulation caused by long-term stagnation of air, and also enables the dehumidification component to continuously process the incoming humid air, further enhancing the moisture-proof performance of the entire power cabinet and maintaining a dry air environment inside the inner cabinet.
[0015] 5. The moisture-proof power cabinet in the humid area is equipped with a check valve. During normal drainage, the accumulated water can push the valve disc to rotate around the shaft to drain the water. After the drainage is completed, the valve disc is reset and fits the rubber ring seal under the elastic force of the spring to prevent external water or moisture from flowing back into the cabinet.

The outlet assembly 7 includes an outlet pipe 71, which is fixedly installed at the edge of the bottom of the inner cabinet 4. The outlet pipe 71 passes through the inner cabinet 4 and the outer cabinet 1 and extends to the bottom thereof. A rubber strip 72 is fixedly connected to the inner wall of the outlet pipe 71. There are several rubber strips 72, and several rubber strips 72 are squeezed and fitted with each other. Multiple rubber strips 72 are squeezed and fitted with each other, which can not only fix the line to prevent it from shaking at will, but also play a certain sealing role to prevent external moisture from entering the inner cabinet 4 from the outlet.
[0020] The second embodiment is based on the first embodiment. Figures 1 to 10As shown, the dehumidification component 8 is fixedly mounted on the outer surface of the inner cabinet 4, and the dehumidification component 8 is sealed and adapted to the inner wall of the outer cabinet 1. The dehumidification component 8 absorbs moisture in the air entering the inner cabinet 4, reduces air humidity, and protects the internal electrical equipment from moisture erosion; The dehumidification assembly 8 includes a bent ring plate 81, which is arranged inside the chamber formed by the outer cabinet 1 and the inner cabinet 4. The top and bottom of the bent ring plate 81 are fixedly installed with sealing rings 88, and the sealing ring 88 is sealed and adapted to the outer side of the inner cabinet 4 to ensure that a relatively sealed space is formed between the bent ring plate 81 and the inner cabinet 4 to prevent air leakage from affecting the dehumidification effect. The surface of the bent ring plate 81 is provided with air holes 83, and a water-absorbing sponge 84 is fixedly installed at the bending of the bent ring plate 81. The air holes 83 are arranged between the water-absorbing sponges 84, and the air holes 83 facilitate air flow in the bent ring plate 81, so that The air can fully contact the water-absorbing sponge 84, which can absorb moisture in the air, play a dehumidifying role, and reduce the air humidity.

A water outlet pipe 86 is fixedly installed in the middle of the bottom of the bent ring plate 81. The water outlet pipe 86 runs through the inner cabinet 4 and the outer cabinet 1 and extends to the bottom thereof. The water outlet pipe 86 guides the accumulated water out of the cabinet to prevent moisture accumulation from affecting the dehumidification and the internal environment of the cabinet. A check valve 87 is fixedly installed at the bottom of the water outlet pipe 86 to prevent external water or moisture from flowing back into the cabinet. The baffle 82 forms a closed space between the bent ring plate 81, the outer cabinet 1 and the inner cabinet 4, so that the air is dehumidified in this limited space, preventing the moist air from entering the inner cabinet 4 through the ventilation hole 12. The water guide sheet 19 penetrates the water outlet pipe 86 and extends to the inside thereof, so that the water in the water collection tank 20 is smoothly introduced into the water outlet pipe 86 and discharged from the cabinet, ensuring that the inside of the cabinet is dry. The guide plate 85 is sealed and fitted with the outer surface of the inner cabinet 4, and the outer bending part of the bent ring plate 81 is sealed and fitted with the inner wall of the outer cabinet 1, so that the baffle 82 divides the enclosed space formed by the bent ring plate 81, the outer cabinet 1 and the inner cabinet 4 into multiple layers. After the humid air enters the enclosed space formed by the bent ring plate 81 and the outer cabinet 1, it is filtered layer by layer in this multi-layer space through the air holes 83 and the water-absorbing sponge 84, thereby efficiently removing moisture from the air.
[0021] The check valve 87 includes a valve body 871, on the inner wall of which a rotating shaft 872 and a rubber ring 874 are fixedly installed. The rubber ring 874 is arranged above the rotating shaft 872. The outer surface of the rotating shaft 872 is rotatably connected with a valve flap 873. The valve flap 873 and the rubber ring 874 are sealed and fitted. A spring 875 is fixedly connected between the outer surface of the valve flap 873 and the inner wall of the valve body 871. During normal drainage, the accumulated water can push the valve flap 873 to rotate around the rotating shaft 872 to drain water. After the drainage is completed, the valve flap 873 is reset and sealed and fitted with the rubber ring 874 under the elastic force of the spring 875 to prevent external water or moisture from flowing back into the cabinet.
[0022] The third embodiment is based on the first and second embodiments. Figures 1 to 8 As shown, the outer surface of the inner cabinet 4 is provided with a leakage groove 16, an arc-shaped water guide groove 17 and a water collecting groove 20, the arc-shaped water guide groove 17 is arranged directly below the leakage groove 16, the arc-shaped water guide groove 17 is an arc-shaped groove with a low middle and high ends, the water collecting groove 20 is arranged in the middle directly below the arc-shaped water guide groove 17, the number of the leakage grooves 16 is nine, and the nine leakage grooves 16 are evenly distributed inside the bent ring plate 81, the leakage groove 16 can collect the accumulated water formed after the water-absorbing sponge 84 absorbs saturation, and guide the water to flow downward, the arc-shaped water guide groove 17 guides the water collected by the leakage groove 16 to the water collecting groove 20, the water guide sheet 19 can guide the water in the water collecting groove 20 into the outlet pipe 86 and discharge it from the cabinet, so as to ensure that the inside of the cabinet is dry, the inside of the leakage groove 16 is installed with a heat dissipation component 18, and the bottom of the water collecting groove 20 is fixedly installed with a water guide sheet 19; The heat dissipation component 18 includes a fixing groove 181, which is opened on the inner wall of the inner cabinet 4. A heat conductive sheet 182 is fixedly installed inside the fixing groove 181. The fixing groove 181 is used to fix the heat conductive sheet 182 to make it stable on the inner wall of the inner cabinet 4. One side of the heat conductive sheet 182 is fixedly connected with a heat sink 183. The heat sink 183 penetrates the inner cabinet 4 and the water leakage groove 16 and extends to the outside thereof. The heat conductive sheet 182 conducts the heat generated by the electrical equipment inside the inner cabinet 4 to the heat sink 183. The heat sink 183 can dissipate the heat to the external environment to play a heat dissipation role and ensure that the internal equipment runs at an appropriate temperature. The heat sink 183 can also cooperate with the dehumidification component 8. When the humid air entering the dehumidification component 8 contacts the heat sink 183, the water vapor condenses on the surface of the heat sink 183 when it is cold and flows into the water leakage groove 16 through the guide sheet 85.
[0023] When in use, the staff turns on the blower 15, which can promote the exchange of air inside and outside the inner cabinet 4 and accelerate the air flow. The operation of the blower 15 causes the air inside the inner cabinet 4 to be discharged, and the outside air enters from the ventilation hole 12. A negative pressure is formed in the space between the outer cabinet 1 and the inner cabinet 4, and the outside air is pressed into the strip air inlet 9. The strip air inlet 9 is connected with the baffle 82, the bent ring plate 81, and the closed space formed between the outer cabinet 1 and the inner cabinet 4. After the humid air enters the closed space formed by the bent ring plate 81 and the outer cabinet 1, the air is filtered layer by layer in this multi-layer space through the air permeable hole 83 and the water-absorbing sponge 84, and the moisture in the air is efficiently removed. At this time, the air contacts the heat sink 183, and the water vapor condenses on the surface of the heat sink 183 when it is cold. The condensed water flows into the water leakage groove 16 through the guide plate 85. The water leakage groove 16 can collect the accumulated water formed after the water-absorbing sponge 84 absorbs saturation and the condensed water on the surface of the heat sink 183, and guide the water to flow downward. Since the arc-shaped water guide groove 17 is an arc-shaped groove with a low middle and high ends, the arc-shaped water guide groove 17 can guide the water collected by the water leakage groove 16 to the water collection groove 20 in the middle. The water guide plate 19 can guide the water in the water collection groove 20 into the outlet pipe 86 and discharge it from the cabinet to ensure that the inside of the cabinet is dry. During normal drainage, the accumulated water can push the valve flap 873 to rotate around the rotating shaft 872 to drain the water. After the drainage is completed, the valve flap 873 is reset and sealed with the rubber ring 874 under the elastic force of the spring 875 to prevent external water or moisture from flowing back into the cabinet.
