Description

Technical Field

[0001] This invention relates to the field of energy storage inverter cabinet technology, and in particular to a protective cabinet for micro energy storage inverters. Background Technology

[0002] In remote rural areas such as mountainous and forested regions, intermittent low voltage problems are prominent in the end-point power grid due to factors such as long power supply radius and large line voltage drop. As the core equipment for solving the low voltage problem at the end of the rural power grid, micro-energy storage inverters usually need to be deployed in outdoor open-air environments, facing multiple harsh conditions such as high temperature exposure, rain and snow, and even short-term water accumulation, which places extremely high demands on their protective cabinets.

[0003] The existing protection design of energy storage inverter cabinets has the following shortcomings: First, the contradiction between protection and heat dissipation is difficult to balance. In order to ensure the protection level of internal electrical components, the cabinets mostly adopt a closed structure. However, the inverter power modules generate a lot of heat when working, and the closed cabinets cannot effectively dissipate the heat, which can easily cause local overheating. Although some solutions use ventilation holes on the cabinets and fans for air cooling, rainwater can easily enter the cabinet through the ventilation holes in rainy or snowy weather, causing internal components to become damp or short-circuited, which greatly reduces the protection performance. Other solutions use louvers with dustproof nets or add rainproof covers, but they cannot actively switch the heat dissipation mode according to the weather conditions, and there is still a risk of rainwater seepage when there is heavy rainfall.

[0004] Secondly, there is a lack of adaptive protection against rain and snow. The heat dissipation channels of existing energy storage cabinets often cannot be sealed in time during rainy weather, and rainwater may enter the cabinet through the heat dissipation holes, causing equipment failure. Some solutions have designed adjustable heat dissipation hole sealing structures, but they require manual operation or rely on active drive mechanisms such as electric push rods, resulting in a response delay. Moreover, in extreme cases such as flooding, there is a lack of effective sealing means at the bottom interface of the cabinet, making it impossible to achieve emergency sealing protection for the entire cabinet. To address this, we propose a protective cabinet for micro energy storage inverters. Summary of the Invention

[0011] Furthermore, the drainage component also includes a transition plate fixedly installed inside the cabinet, and a second spring is fixedly connected to the inside of the transition plate. Heat dissipation pipes are fixedly installed at equal intervals on the side of the transition plate, and the other end of the heat dissipation pipes extends through the protective component and out of its interior position. The heat dissipation pipes are located inside the cabinet near the inner side. A trigger rod is fixedly installed at the lower center of the mating plate and the trigger rod is attached to the upper side of the movable plate.

[0012] Furthermore, the auxiliary plate is located on the lower side of the base plate, and the second support component includes floats symmetrically fixedly installed on the lower side of the auxiliary plate.

[0013] Furthermore, an electric actuator is fixedly installed at the center of the upper side of the cabinet, and a connecting rope is fixedly connected to the output end of the electric actuator, with the other end of the connecting rope fixedly connected to the lower side of the water storage box.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention sets up a water storage box and a matching cylinder, and uses the gravity of rainwater to drive the water storage box to move downward, thereby driving the baffle assembly to rotate to block or partially block the heat dissipation groove. At the same time, it drives the blocking plate to block the first opening, realizing mechanical linkage that automatically switches the heat dissipation mode according to the amount of rainfall. The response is timely and reliable, and no additional electrical drive components are required, reducing the failure rate and manufacturing cost.

[0015] 2. This invention, by setting up a water pump, a matching plate, a fixed pipe, and a heat dissipation pipe, allows rainwater collected in a water storage box to be introduced into the heat dissipation pipe inside the cabinet for circulating liquid cooling after the heat dissipation groove is closed by a baffle in rainy weather. This realizes the transformation of rainwater from waste to treasure, which not only makes up for the problem of insufficient heat dissipation capacity after the air duct is closed by water cooling, but also avoids rainwater from directly contacting electrical components, ensuring heat dissipation efficiency and electrical safety under rainy weather conditions.

[0016] 3. This invention sets up an auxiliary component, arranging a float-driven auxiliary plate at the bottom of the cabinet. When the water level rises, the float generates buoyancy to push the auxiliary plate up to seal the bottom plate. At the same time, a pressure sensor detects the feedback signal and controls the electric push rod to actively pull the water storage box down to achieve the sealing of the entire cabinet. This realizes automatic emergency protection under extreme water flooding conditions and ensures that the internal components of the cabinet can still operate normally in a short-term water accumulation environment.

[0017] 4. This invention achieves dual dehumidification of the airflow entering the cabinet by setting a drying plate at the heat dissipation groove and setting a desiccant at the auxiliary plate, which effectively reduces the risk of humid air corroding internal electrical components in the air-cooled mode. It is suitable for rural power grid environments in mountainous and forested areas with high humidity and frequent rain and fog. Attached Figure Description

[0020] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figures 1 to 4 As shown in the figure, a protective cabinet for a micro-energy storage inverter includes a cabinet body 1. Sealing strips are provided on the movable door and sides of the cabinet body 1, ensuring the cabinet body 1 is completely sealed when the movable door is closed. A top plate 11 is fixedly installed on the upper side of the cabinet body 1. The four sides of the top plate 11 are bent downwards and fitted to the sides of the cabinet body 1, covering the upper part of the cabinet body 1. First openings 111 are equidistantly provided on the sides of the cabinet body 1. Rectangular heat dissipation slots 13 are symmetrically and equidistantly provided on both sides of the cabinet body 1. A drying plate 15 is fixedly installed on the inner side of the cabinet body corresponding to the heat dissipation slots 13. A cooling fan 14 is fixedly installed through the top plate 11 and covers the cooling fan 14. A drying plate 15 is provided on the sides of the cabinet body corresponding to the heat dissipation slots 13 and the top plate 11. The cabinet is equipped with a protective component 2. During normal use, the cooling fan 14 operates, allowing airflow to enter the cabinet 1 through the cooling duct 13. An energy storage inverter is installed inside the cabinet 1. The airflow then exits through the top plate 11 to the first opening 111 for heat dissipation. When it rains, the rainwater can trigger the closure of the cooling duct 13, allowing water cooling. A base plate 12 is fixedly installed on the lower side of the cabinet 1. The base plate 12 is a U-shaped frame. A second opening 121 is symmetrically and equidistantly opened on the base plate 12 of the cabinet 1. An auxiliary component 3 is installed on the lower side of the cabinet 1 corresponding to the position of the base plate 12. During normal use, airflow can flow into the cabinet 1 through the second opening 121 for heat dissipation. The auxiliary component 3 assists in drying the airflow. When the water level is high, the auxiliary component 3 can be triggered to seal the lower side of the cabinet 1.

[0022] like Figures 3 to 11As shown, the protective component 2 includes baffles 21, which are equidistantly arranged on both sides of the cabinet 1. The baffles 21 are positioned corresponding to the heat dissipation slots 13. The baffles 21 are rectangular plates. Fixing brackets 211 are symmetrically arranged on both sides of the baffles 21 and are fixedly installed on the side of the cabinet 1. The fixing brackets 211 are also rectangular plates. A rotating shaft 212 is fixedly installed through the side of the baffles 21 and is rotatably mounted through the fixing brackets 211 at both ends. The rotating shaft 212 is a cylindrical rod. A second gear 2 is fixedly sleeved on the side of the rotating shaft 212 at the uppermost position. 21. A first gear 22 is fixedly sleeved on the side of the rotating shaft 212 at other positions. The width ratio of the second gear 221 to the first gear 22 is 2:1. A toothed belt 222 is meshed and sleeved on the side of the first gear 22 and the second gear 221. A rack 23 is meshed on the side of the second gear 221 and is horizontally arranged with the side of the cabinet 1. A fixing plate 231 is fixedly installed on the side of the cabinet 1 corresponding to the position of the rack 23. The fixing plate 231 is a rectangular plate. A constraint rod 233 is fixedly installed on the upper side of the rack 23 and passes through the fixing plate. A fixed plate 231 extends outwards, and a constraint rod 233 is a cylindrical rod. A movable plate 232, which is rectangular, is fixedly installed on the upper side of the constraint rod 233. A first spring 234 is fixedly connected between the movable plate 232 and the side of the fixed plate 231, and the first spring 234 is movably sleeved on the side of the constraint rod 233. Specifically, when the movable plate 232 is pressed downwards, the movable plate 232 compresses and drives the rack rod 23 downwards through the constraint rod 233. The rack rod 23 meshes with the second gear 221, and synchronously drives the second gear through the toothed belt 222. When gear 221 rotates in conjunction with the first gear 22, the second gear 221 and the first gear 22 can drive the corresponding rotating shaft 212 to rotate, so that the baffle 21 can be rotated by the rotating shaft 212. The baffle 21 can seal the heat dissipation groove 13. Conversely, when the movable plate 232 is not pressed, the first spring 234 elastically supports the movable plate 232 to pull the rack 23 upward. The rack 23 meshes with the second gear 221, so that the baffle 21 tilts and swings at the heat dissipation groove 13. When the baffle 21 rotates, its side is always in contact with the side of the cabinet 1. A water storage box 24 is provided on the upper side of the top plate 11. The water storage box 24 is a rectangular box with an open top. A matching cylinder 241 is fixedly connected between the lower side of the water storage box 24 and the upper side of the top plate 11. The matching cylinder 241 is a U-shaped cylinder with a continuously corrugated cross section. A filter plate 242 is fixedly provided on the upper side of the water storage box 24. The filter plate 242 is a perforated plate. A movable pipe 243 is fixedly provided on the lower side of the water storage box 24, and the movable pipe 243 penetrates the top plate 11 and extends into it. The movable pipe 243 is a Z-shaped round pipe, and the other end of the movable pipe 243 extends out through the top plate 11. A water pump 244 is fixedly provided inside the water storage box 24 at the position corresponding to the movable pipe 243. The water pump 244 and the movable pipe 243 are connected to the water storage box 24. Pipe 243 is connected, and water pump 244 can draw water from inside water storage box 24. A blocking plate 245 is fixedly sleeved on the side of movable pipe 243 and the blocking plate 245 is set corresponding to the first opening 111. The blocking plate 245 is a U-shaped plate. Specifically, when it rains, rainwater flows into the water storage box 24 after being filtered by filter plate 242. The weight of the rainwater causes the water storage box 24 to press and deform the matching cylinder 241. The water storage box 24 moves downward and simultaneously drives the movable pipe 243 to move downward. The blocking plate 245 on the side of movable pipe 243 can then fit against the inside of top plate 11 to seal the first opening 111. Then, water pump 244 draws rainwater from inside water storage box 24 and discharges the rainwater through movable pipe 243. A mating plate 25 is provided on the side of the cabinet 1 below the movable pipe 243. The mating plate 25 is a hollow rectangular plate. A mating pipe 251 is fixedly installed through the upper side of the mating plate 25 and is snapped into the movable pipe 243. The mating pipe 251 is a circular pipe. A fixing pipe 26 is symmetrically arranged on the lower side of the mating plate 25 and is fixedly installed through the side of the cabinet 1. One end of the fixing pipe 26 extends to the inside of the cabinet 1, and the other end is movably installed inside the mating plate 25. A notch is opened at the port of the fixing pipe 26 inside the mating plate 25 to prevent the port from being blocked by the bottom of the mating plate and affecting the water flow. A second spring is movably sleeved on the side of the fixing pipe 26. Spring 261 and second spring 261 are located between the side of fixed tube 26 and the lower side of mating plate 25. A transition plate 27 is fixedly installed inside the cabinet 1, and the second spring 261 is fixedly connected to the interior of the transition plate 27. The transition plate 27 is a hollow rectangular plate. Heat dissipation pipes 28 are fixedly installed at equal intervals on the side of the transition plate 27, and the other end of the heat dissipation pipes 28 extends through the protective component 2 and out of its interior. The heat dissipation pipes 28 are located inside the cabinet 1 near the inner side. The heat dissipation pipes 28 are circular pipes made of heat-conducting material. A trigger rod 29 is fixedly installed at the center of the lower side of mating plate 25, and the trigger rod 29 is attached to the upper side of movable plate 232. Specifically, when rainwater accumulates in the water storage box 24, the movable tube 243 moves downward. When the corresponding mating pipe 251 pushes the mating plate 25 downward, the mating plate 25 slides on the side of the fixed pipe 26. Simultaneously, the trigger rod 29 presses down on the upper side of the movable plate 232 along with the mating plate 25. The movable plate 232 then presses down on the rack rod 23 and engages with the second gear 221 via the constraint rod 233, causing the baffle 21 to rotate and seal the heat dissipation groove 13. At this time, the rainwater pumped by the water pump 244 flows through the movable pipe 243 into the mating pipe 251 and then into the mating plate 25. Subsequently, the rainwater flows through the fixed pipe 26 into the heat dissipation pipe 28, where it conducts heat away from the interior of the cabinet 1. Thus, during light rain, the water storage box 24 does not completely fall onto the top plate 11, and the baffle 21 and the blocking plate 245 do not... The heat dissipation slot 13 and the first opening 111 are sealed. The trigger rod 29 slightly presses down the movable plate 232, causing the baffle 21 to rotate at a certain angle but not completely fit the cabinet, forming a canopy effect. At this time, the cooling fan 14 performs air cooling for the inside of the cabinet 1, and the water pump 244 performs water cooling for the inside of the cabinet 1, assisting in the heat dissipation operation inside the cabinet 1. During heavy rain, the water storage box 24 falls completely to the top plate 11. The baffle 21 and the blocking plate 245 completely seal the heat dissipation slot 13 and the first opening 111. At this time, only the water pump 244 performs water cooling, thus ensuring that no water vapor enters the inside of the cabinet 1 during rainy days. Its internal energy storage inverter can be effectively protected, and energy storage compensation is provided for the low voltage environment of the outdoor rural power grid.

[0023] like Figure 3 , Figure 4 and Figures 10 to 12 As shown, auxiliary component 3 includes auxiliary plate 31, which is located on the lower side of base plate 12. Auxiliary plate 31 is rectangular. Desiccant is placed on the upper side of auxiliary plate 31. Float 32 is symmetrically fixed on the lower side of auxiliary plate 31. Connecting rods 33 are symmetrically fixed on the upper side of auxiliary plate 31, penetrating the base plate 12 into its interior. Connecting rods 33 are cylindrical rods with a "T"-shaped cross-section. Pressure sensor 34 is movably sleeved on the side of connecting rod 33 and fixedly installed on the inner side of base plate 12. Support cylinder 35 is fixedly connected between pressure sensor 34 and the side of connecting rod 33, and movably sleeved on the side of connecting rod 33. Support cylinder 35 is a corrugated cylinder made of elastic material. Electric actuator 36 is fixedly installed at the upper center of cabinet 1. Connecting rope 37 is fixedly connected to the output end of electric actuator 36, and the other end of connecting rope 37 is fixedly connected to the lower side of water storage box 24. The connecting rope 37 is a round steel wire rope. Specifically, during normal use, the airflow can pass through the side of the auxiliary plate 31 and be dehumidified by the desiccant, and then enter the cabinet 1 through the second opening 121 for auxiliary heat dissipation. When the water level is too high, the float 32 can support the auxiliary plate 31 to be attached to the lower side of the bottom plate 12 by its own buoyancy. The auxiliary plate 31 seals the bottom plate 12. The electrical wires inside the cabinet 1 extend out through the lower side of the cabinet 1. The auxiliary plate 31 is movably connected to the side of the wires by the sealing ring. At this time, the connecting rod 33 pulls the support cylinder 35 to deform. The pressure sensor 34 detects its own pressure change and feeds it back to the controller. The controller controls the electric push rod 36 to pull the connecting rope 37 downward. The connecting rope 37 can then actively pull the water storage box 24 downward to be attached to the upper side of the top plate 11. The downward movement of the water storage box 24 triggers the baffle 21 to rotate and seal the heat dissipation groove 13. At this time, the entire cabinet 1 is in a sealed protection state, ensuring that the electrical appliances inside the cabinet 1 can operate normally when flooded.

[0024] Working principle: Under normal conditions, the energy storage inverter is installed inside the cabinet 1, and its circuit wires pass through the bottom of the cabinet 1. The auxiliary plate 31 is movably connected to the side of the wires through a sealing element. At this time, the cooling fan 14 is running normally, and the airflow enters the top plate 11 through the heat dissipation slot 13. After being dried by the drying plate 15, the gas is discharged through the first opening 111 inside the top plate 11, thus providing air cooling for the inside of the cabinet 1. In addition, the airflow can flow into the inside of the cabinet 1 through the second opening 121 under the bottom plate 12. After being dehumidified by the desiccant on the upper side of the auxiliary plate 31, it assists in providing air cooling for the inside of the cabinet 1. In this way, the air inlet and outlet are not affected by rainwater, effectively ensuring the normal operation of the internal micro energy storage inverter. When it rains, especially when there is little rainwater, the rainwater is filtered through the filter plate 242 and accumulates inside the water storage box 24. The water storage box 24 causes the compression sleeve 241 to deform and not fit properly against the upper side of the top plate 11. At this time, the movable tube 243 moves downward inside the top plate 11, compressing the corresponding fitting tube 251 and causing the fitting plate 25 to move downward. The synchronous trigger rod 29 compresses the movable plate 232, causing it to move downward. The movable plate 232, through the constraint rod 233, drives the rack rod 23 downward to mesh with the second gear 221. Through the toothed belt 222, the second gear 221 rotates synchronously with the first gear 22, and the corresponding baffle 21... The angle can be tilted downwards to protect the heat dissipation groove 13 from rainwater entering the cabinet 1, forming a canopy effect. At this time, the water pump 244 draws rainwater through the movable pipe 243, the matching pipe 251, the matching plate 25, and the fixed pipe 26 to the inside of the transition plate 27, and then flows through the transition plate 27 to the heat dissipation pipe 28 for discharge. The heat dissipation pipe 28 conducts heat to the inside of the cabinet 1 to dissipate heat. At this time, the baffle 21 and the blocking plate 245 do not block the heat dissipation groove 13 and the first opening 111. The synchronous heat dissipation fan 14 runs and enters the airflow through the heat dissipation groove 13 and the second opening 121, and discharges heat from the first opening 111. When there is a lot of rain, the water storage box 24 is squeezed downward by the gravity of the rainwater and deforms the cylinder 241. The water storage box 24 is attached to the upper side of the top plate 11. Similarly, the movable tube 243 moves downward. At this time, the baffle 21 rotates and attaches to the side of the cabinet 1 to seal the heat dissipation groove 13. The blocking plate 245 is attached to the inside of the top plate 11 to seal the first opening 111. At this time, only the water pump 244 draws out the rainwater and uses the rainwater to perform liquid cooling heat dissipation inside the cabinet 1. In this way, the heat dissipation groove 13 on the side of the cabinet 1 is directly sealed, eliminating the possibility of rainwater entering the inside of the cabinet 1. When flooded, due to the installation position of cabinet 1, water may accumulate or the water level may rise. The float 32 generates buoyancy on the upper side of the water, pushing the auxiliary plate 31 upward to adhere to the lower side of the base plate 12. The auxiliary plate 31 slides on the side of the wire and is protected by the sealing element. At this time, the connecting rod 33 pulls the support cylinder 35 to deform. The pressure sensor 34 detects the pressure change of the support cylinder 35 and feeds it back to the controller. The controller controls the electric push rod 36 to pull the connecting rope 37 downward. The connecting rope 37 actively pulls the water storage box 24 downward to adhere to the upper side of the top plate 11. At this time, the first opening 111, the heat dissipation groove 13 and the lower side of the base plate 12 are all sealed. The entire cabinet 1 is in a sealed and protected state, ensuring that the cabinet 1 can operate normally when flooded. The water pump 244 can generate water circulation to perform liquid cooling heat dissipation inside the cabinet 1.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
