Description

Technical Field

[0001] The present invention relates to the technical field related to power cabinets, and in particular to an outdoor power energy storage cabinet. Background Art

[0002] The outdoor power energy storage cabinet is an integrated energy storage device, mainly used for storing and managing electric energy. It is widely used in power systems, communication base stations, industrial power and other fields. Since electricity consumption has peak and valley periods, there are large differences in electricity consumption in different periods. However, the electricity generated by power generation equipment will be wasted if it is not used after it is generated. Therefore, in order to avoid energy waste, excess electricity will be stored in the energy storage cabinet. The energy storage cabinet stores electric energy during low electricity consumption and releases electric energy during peak electricity consumption. It can also be used to balance the load of the power grid and provide emergency power when the main power supply fails to ensure the operation of key equipment.

[0003] A large number of battery packs and inverters are usually installed at the bottom of the outdoor power cabinet. The battery packs and inverters will release a lot of heat when storing and releasing electricity, which needs to be dissipated in time by cooling fans. However, the air inlet of the cooling fan will carry a lot of dust into the power cabinet, affecting the internal circuit of the power cabinet. In addition, dust will also cause the filter to be blocked, affecting heat dissipation and reducing the heat exchange rate inside the power cabinet. In addition, rainwater will enter the cabinet through the air inlet of the cooling fan during the rainy season, causing malfunctions inside the power cabinet. Therefore, although a larger air inlet increases the internal heat exchange rate, it also increases the risk of rainwater entering the cabinet during the rainy season. In addition, the dust on the filter is located at the bottom of the cabinet, which is time-consuming and labor-intensive to maintain and clean manually, and is likely to affect the scattered internal circuits, causing circuit malfunctions, and also poses certain safety hazards to the operators.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, adaptive angle adjustment is achieved by cooperating with the rainwater component through the strip baffle of the waterproof component. The gravity of different rainwater drives the rainwater gutter to drop to different positions, and the corresponding strip baffle will rotate to different angles, which does not affect daily heat dissipation and can also improve the waterproof effect of the power cabinet in the rainy season. The maintenance component realizes regular inspection and maintenance of the battery pack in the battery rack. The maintenance component is linked to enable the cleaning scraper and auxiliary scraper in the dust scraper component to clean the dust filter, which can not only maintain the battery pack, but also clean the dust and improve the heat dissipation effect inside the power cabinet.

[0017] 2. In the present invention, the dust on the dust filter is scraped and cleaned by the relative movement of the cleaning scraper on the limiting base, and the dust filter on the inner side of the chain is cleaned by the auxiliary scraper on the L-shaped side rod. The dust cleaned by the cleaning scraper and the auxiliary scraper is discharged into the inner bottom of the power cabinet through the storage groove. The cleaning of the dust filter increases the air intake of the cooling fan and improves the heat dissipation effect of the battery pack.

[0018] 3. In the present invention, the inclination angle of the strip baffle is adjusted according to the gravity of the rain gutter, and the closing degree of the strip baffle is adjusted accordingly, thereby effectively improving the waterproof ability of the power cabinet. When the rainwater is completely discharged from the rain gutter, the connecting rod and the connecting rod undergo a reset movement. At the same time, the strip baffle uses the counterweight block at the inner end to complete the reset movement under the action of gravity, so that the strip baffle undergoes a stable and smooth horizontal reset movement.

[0019] 4. In the present invention, the chain movement of the dust scraper assembly drives the cleaning scraper to move, the first connecting rod and the second connecting rod will be pulled to move relative to each other, and the limiting slide plates connected to the bottom of the first connecting rod and the second connecting rod will also move relative to each other on the limiting base. The cleaning scraper on the limiting base moves relative to each other to scrape and clean the dust on the dust filter. The stroke of the cleaning scraper is the length of the chain, and the dust filter corresponding to the chain position is cleaned by the auxiliary scraper on the L-shaped side rod, thereby achieving comprehensive cleaning of the dust filter.

[0020] 5. In the present invention, the battery pack is pulled out of the power cabinet by the rollers under the battery rack and the rolling grooves, which makes it convenient for workers to perform maintenance and inspection around and inside the battery pack, improves the safety performance of the power cabinet, effectively extends the service life of the battery pack, does not affect the battery pack, and also improves the safety performance of workers.

[0021] 6. In the present invention, multiple groups of rainwater baffles in the rain gutter can be directly lifted and disassembled through the mounting seat. Workers can clean up the garbage in the rain gutter in time, effectively improving the water storage and drainage capacity of the rain gutter. The rain gutter will not retain rainwater in the non-rainy season. At the same time, it can also ensure the residence time of rainwater in the rain gutter during the rainy season, and cleverly use rainwater to change the angle of the strip baffle.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific examples, but the following examples are only preferred embodiments of the present invention, not all. Based on the examples in the embodiments, other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention. The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels.

[0039] Example: Figure 1 、 Figure 2 、 Figure 5 、 Figure 10 and Figure 12 As shown, an outdoor power energy storage cabinet includes a power cabinet body 10, a battery pack 12 is installed on the inner bottom of the power cabinet body 10 through a battery rack 11, a back cover 13 with a cooling fan 14 is installed on the back of the power cabinet body 10, and a waterproof component for adjusting the air intake of the cooling fan 14 is provided inside the back cover 13. The strip baffle 20 in the waterproof component rotates at an angle during the rainy season to waterproof the power cabinet body 10. When the rainy season comes, the gravity of the rainwater drives the rainwater gutter 30 to descend to different positions, and the corresponding strip baffle 20 will rotate to different angles, thereby stably and effectively preventing rainwater from entering the power cabinet body 10.

[0040] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The waterproof component also includes an L-shaped rotating plate 21 that drives the strip baffle 20 to rotate. The rear cover 13 is fixedly installed with a rotating frame 22 on the side away from the power cabinet 10. The rotating frame 22 is an internal hollow structure. Several strip baffles 20 are arranged inside the rear cover 13 through a rotating shaft. The L-shaped rotating plate 21 is installed inside the rotating frame 22 through a fixed rotating shaft 29. The L-shaped rotating plate 21 is provided with an arc-shaped rotating groove 23 at one end close to the power cabinet 10. The strip baffle 20 is fixedly installed with an arc-shaped rotating rod 24 that matches the size of the arc-shaped rotating groove 23 at one end of the rotating frame 22, and the arc-shaped rotating rod 24 moves in the arc-shaped rotating groove 23. The L-shaped rotating plate 21 is movably connected to a connecting block 25 through a rotating shaft at one end away from the power cabinet 10. A connecting rod 26 is connected between several connecting blocks 25, and the bottom of the connecting rod 26 extends to the outside of the bottom of the rotating frame 22. The bottom end of the connecting rod 26 is fixedly mounted on the rain gutter 30. The rotating frame 22 is provided with an arc-shaped movable groove 27 that matches the size of the arc-shaped rotating rod 24 on the side close to the strip baffle 20, and the arc-shaped rotating rod 24 movably passes through the arc-shaped movable groove 27. A counterweight block 28 is embedded in the strip baffle 20 at one end close to the power cabinet 10, and the counterweight block 28 is used to reset the strip baffle 20.

[0041] See Figure 4 、 Figure 5 and Figure 6 When rainwater accumulates in the rain gutter 30, the gravity of the rainwater drives the rain gutter 30 to move downward. During the descending process, the rain gutter 30 drives the L-shaped rotating plate 21 in the rotating frame 22 to rotate under the action of the fixed rotating shaft 29 through the connecting rod 26 and the connecting block 25. The L-shaped rotating plate 21 drives the arc rotating rod 24 on the strip baffle 20 to move in the arc rotating groove 23 through the arc rotating groove 23, so that the inner end of the strip baffle 20 rotates and tilts up, while the outer end of the strip baffle 20 faces closed. In this way, rainwater in the rainy season will not enter the interior of the power cabinet 10, and the greater the rain, the more the rain gutter 30 drops. At this time, the greater the inclination angle of the strip baffle 20, that is, the degree of closure is relatively large, which effectively prevents rainwater from entering the power cabinet 10 during heavy rain. When the rainwater is completely discharged from the rain gutter 30, the connecting rod 26 and the connecting rod 26 perform a reset movement. At the same time, the strip baffle 20 uses the counterweight block 28 at the inner end to complete the reset movement under the action of gravity, so that the strip baffle 20 performs a stable and smooth horizontal reset movement.

[0042] See Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8The bottom of the back cover 13 is provided with a rainwater assembly. The rainwater gutter 30 in the rainwater assembly and the waterproof assembly perform adaptive rotation on the strip baffle 20. The rainwater assembly also includes a rainwater baffle 31. The rainwater gutter 30 is evenly installed with a plurality of mounting seats 32 on the side close to the power cabinet 10. The mounting seats 32 are movably connected with the rainwater baffle 31. The rainwater baffle 31 in the rainwater gutter 30 is alternately provided with drainage holes 33. The rainwater baffle 31 cooperates with the drainage holes 33 to achieve both slowing down and draining the rainwater. The rain gutter 30 is provided with a water outlet hole 34 at the bottom of both ends, and the power cabinet 10 is provided with a support groove 35 at the bottom of the rear cover 13. A support column 36 is fixedly installed in the support groove 35, and a support block 37 is connected to the outside of the support column 36. The support block 37 is fixedly installed at both ends of the rain gutter 30, and a telescopic spring 38 is fixedly installed between the bottom of the support block 37 and the power cabinet 10, and the telescopic spring 38 is movable outside the support column 36.

[0043] See Figure 4 、 Figure 5 、 Figure 7 and Figure 8 When the rainy season comes, as rainwater is continuously collected in the rain gutter 30, the rainwater in the rain gutter 30 will stay for a period of time under the blocking effect of the rainwater baffle 31 and the drainage hole 33, and the rainwater accumulated in the rain gutter 30 will be discharged from the water outlet hole 34 relatively slowly. When rainwater stays in the rain gutter 30, the gravity of the rainwater drives the rain gutter 30 to move downward, and at the same time, the support block 37 connected to the rain gutter 30 stores force and compresses the telescopic spring 38 at the bottom. After the rainwater is discharged, the compressed telescopic spring 38 drives the rain gutter 30 to reset. The multiple groups of rainwater baffles 31 in the rain gutter 30 can be directly lifted and disassembled through the mounting seat 32, and then the workers can clean up the garbage in the rain gutter 30 in time, effectively improving the water storage and drainage capacity of the rain gutter 30.

[0044] See Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 14, a dust filter 15 is installed inside the back cover 13, which effectively blocks the dust in the air intake, and a dust scraping assembly for cleaning the dust filter 15 is provided inside the back cover 13. The dust scraping assembly includes a cleaning scraper 40 that is movable on the outside of the dust filter 15 and a limiting base 50 installed at the bottom of the back cover 13. The back cover 13 is movably connected to the first gear 51 and the second gear 52 through a rotating shaft, and a chain 53 is connected between the first gear 51 and the second gear 52. The limiting base 50 is provided with a limiting slide 54, and the limiting slide 54 is connected to the limiting slide 55 through a limiting slider 56. The top of the limiting slide 55 is fixedly installed with a movable frame 46, and the top of the movable frame 46 near the first gear 51 is connected to the first connecting rod 41 through a rotating shaft, and the first connecting rod 41 is connected to the chain 53 located at the second gear 52. The top of the movable frame 46 near the second gear 52 is connected to the second connecting rod 42 through a rotating shaft, and the second connecting rod 42 is connected to the chain 53 located at the first gear 51. The first connecting rod 41 is located on the top side of the chain 53, and the second connecting rod 42 is located on the bottom side of the chain 53. The top of the limiting slide 55 is fixedly installed with a cleaning scraper 40, and the cleaning scraper 40 near the second gear 52 is connected to an L-shaped side rod 43, and the L-shaped side rod 43 is fixedly installed with an auxiliary scraper 44. The cleaning scraper 40 and the auxiliary scraper 44 move between the strip baffle 20 and the dust filter 15. The cleaning scraper 40 moves in the cleaning groove 45 provided at the bottom of the rear cover 13. The rear cover 13 is provided with a storage groove 47 for collecting dust at the bottom of the dust filter 15. The scraped dust will enter the storage groove 47 and be discharged to the inner bottom of the power cabinet 10.

[0045] See Figure 8 、 Figure 9 、 Figure 10 and Figure 14 , the first gear 51 and the second gear 52 rotate, the first connecting rod 41 and the second connecting rod 42 on the chain 53 will be pulled to move relative to each other, and the limiting slide plate 55 connected at the bottom of the first connecting rod 41 and the second connecting rod 42 will also move relative to each other on the limiting base 50, and the cleaning scraper 40 on the limiting base 50 moves relative to each other to scrape and clean the dust on the dust filter 15. The stroke of the cleaning scraper 40 is the length of the chain 53, and the dust filter 15 corresponding to the position of the chain 53 is cleaned by the auxiliary scraper 44 on the L-shaped side rod 43. The dust cleaned by the cleaning scraper 40 and the auxiliary scraper 44 is discharged into the inner bottom of the power cabinet 10 through the storage groove 47. The cleaning of the dust filter 15 increases the air intake to the cooling fan 14 and improves the heat dissipation effect of the battery pack 12.

[0046] See Figure 1 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 , a maintenance component that drives the battery rack 11 to move is provided at the inner bottom of the power cabinet 10. The rack plate 61 in the maintenance component synchronously drives the cleaning scraper 40 to clean the outside of the dust filter 15 during the movement. A rolling groove 16 is provided at the inner bottom of the power cabinet 10. Heat dissipation windows 17 are provided on both sides of the bottom of the power cabinet 10. The heat generated by the battery pack 12 is discharged from the interior of the power cabinet 10 through the heat dissipation windows 17. Rollers 80 that are movable in the rolling grooves 16 are installed around the bottom of the battery rack 11. The maintenance component also includes a rack plate 61 installed at the bottom of the battery rack 11 through a motion block 62. The second gear 52 is fixedly installed with a connecting shaft 63 on the side close to the power cabinet 10. The connecting shaft 63 is fixedly installed with a first bevel gear 64 located at the bottom of the power cabinet 10. The power cabinet A supporting shaft 65 is movably provided at the inner bottom of 10, and a second bevel gear 66 movably meshed with the first bevel gear 64 is fixedly installed on the top of the supporting shaft 65, and a first pulley 67 is fixedly installed on the bottom end of the supporting shaft 65. The inner bottom of the power cabinet 10 is connected to a second pulley 68 matching the first pulley 67 through a rotating shaft, and a driving gear 69 movably meshed with the rack plate 61 is provided on the top of the second pulley 68. A transmission belt 70 is connected between the first pulley 67 and the second pulley 68. A fixed base 60 is installed at the bottom of the power cabinet 10, and the rack plate 61 is slidably connected to the fixed base 60. The moving block 62 moves in the limit groove 18 opened at the bottom of the power cabinet 10, and L-shaped scrapers 19 for cleaning the heat dissipation window 17 are installed on both sides of the battery rack 11.

[0047] See Figure 12 、 Figure 13 、 Figure 14 and Figure 15 When the battery rack 11 is pulled out of the power cabinet 10 by the worker, the connecting block under the battery rack 11 drives the rack plate 61 on the fixed base 60 to move through the limit slot 18, and the rack plate 61 engages and drives the driving gear 69 and the second pulley 68 to rotate during the movement. The second pulley 68 drives the first pulley 67 on the supporting shaft 65 to rotate synchronously through the transmission belt 70. The second bevel gear 66 on the supporting shaft 65 will engage the first bevel gear 64 to drive the connecting shaft 63 to rotate. The connecting shaft 63 drives the second gear 52 to move, and the second gear 52 drives the first gear 51 to move through the cooperation of the chain 53. The L-shaped scrapers 19 on both sides of the battery rack 11 are used to clean the dust on the inside of the heat dissipation window 17, thereby improving the outlet efficiency of the air outlet and effectively preventing dust from blocking the heat dissipation window 17. After the maintenance and inspection are completed, the battery rack 11 is reset.

[0048] Working principle: During daily use of the power cabinet 10, the battery pack 12 at the bottom is cooled and blown by the cooling fan 14 in the back cover 13. The cooling fan 14 drives the external air to the periphery of the battery pack 12 through the dust filter 15 in the back cover 13, and blows the hot air generated around the battery pack 12 out through the heat dissipation windows 17 on both sides, thereby realizing the exchange of hot air inside the power cabinet 10 and improving the heat dissipation effect inside the power cabinet 10.

[0049] During normal heat dissipation, the strip baffles 20 in the back cover 13 are in a horizontally parallel state. At this time, the air intake of the cooling fan 14 is the largest. When the rainy season comes, as rainwater is continuously collected in the rain gutter 30, the rainwater in the rain gutter 30 will stay for a period of time under the blocking effect of the rainwater baffles 31 and the drainage holes 33. The rainwater accumulated in the rain gutter 30 is discharged from the water outlet holes 34 relatively slowly. When the rainwater stays in the rain gutter 30, the gravity of the rainwater drives the rain gutter 30 to move downward. At the same time, the support block 37 connected to the rain gutter 30 stores force and compresses the telescopic spring 38 at the bottom. The rain gutter 30 passes through the bottom during the descent process. The connecting rod 26 and the connecting block 25 drive the L-shaped rotating plate 21 in the rotating frame 22 to realize rotational movement under the action of the fixed rotating shaft 29. The L-shaped rotating plate 21 drives the arc-shaped rotating rod 24 on the strip baffle 20 to move in the arc-shaped rotating groove 23 through the arc-shaped rotating groove 23, so that the inner end of the strip baffle 20 rotates and tilts up, while the outer end of the strip baffle 20 is closed. In this way, rainwater in the rainy season will not enter the interior of the power cabinet 10. Moreover, the heavier the rain, the more the rain gutter 30 drops. At this time, the greater the inclination angle of the strip baffle 20, that is, the greater the degree of closure, effectively preventing rainwater from entering the power cabinet 10 during heavy rain.

[0050] During maintenance, the multiple groups of rainwater baffles 31 in the rain gutter 30 can be directly lifted and disassembled through the mounting seat 32, and then the workers can clean up the garbage in the rain gutter 30 in time, effectively improving the water storage and drainage capacity of the rain gutter 30.

[0051] The battery pack 12 in the power cabinet 10 is an important module and requires regular maintenance and inspection by workers. During the inspection process, the worker only needs to use the rollers 80 under the battery rack 11 and the rolling grooves 16 to pull the battery pack 12 out of the power cabinet 10. This facilitates the worker to perform maintenance and inspection around and inside the battery pack 12, improves the safety performance of the power cabinet 10, and effectively extends the service life of the battery pack 12.

[0052] When the battery rack 11 is pulled out of the power cabinet 10 by the worker, the connecting block under the battery rack 11 drives the rack plate 61 on the fixed base 60 to move through the limiting groove 18, and the rack plate 61 engages and drives the driving gear 69 and the second pulley 68 to rotate during the movement. The second pulley 68 drives the first pulley 67 on the supporting shaft 65 to rotate synchronously through the transmission belt 70. The second bevel gear 66 on the supporting shaft 65 engages with the first bevel gear 64 to drive the connecting shaft 63 to rotate. The connecting shaft 63 drives the second gear 52 to move. The second gear 52 drives the first gear 51 to move through the cooperation of the chain 53.

[0053] As the first gear 51 and the second gear 52 rotate, the first connecting rod 41 and the second connecting rod 42 on the chain 53 will be pulled to move relative to each other, and the limiting slide plate 55 connected to the bottom of the first connecting rod 41 and the second connecting rod 42 will also move relative to each other on the limiting base 50. The cleaning scraper 40 on the limiting base 50 moves relative to each other to scrape and clean the dust on the dust filter 15. The stroke of the cleaning scraper 40 is the length of the chain 53, and the dust filter 15 corresponding to the position of the chain 53 is cleaned by the auxiliary scraper 44 on the L-shaped side rod 43. The dust cleaned by the cleaning scraper 40 and the auxiliary scraper 44 is discharged into the inner bottom of the power cabinet 10 through the storage groove 47. The cleaning of the dust filter 15 increases the air intake to the cooling fan 14 and improves the heat dissipation effect of the battery pack 12;

[0054] At the same time, the L-shaped scrapers 19 on both sides of the battery rack 11 are used to clean the dust on the inner side of the heat dissipation window 17, thereby improving the outlet efficiency of the air outlet and effectively preventing dust from blocking the heat dissipation window 17. After the maintenance and inspection is completed, the battery rack 11 is reset. Similarly, the first connecting rod 41 and the second connecting rod 42 on the chain 53 will also drive the cleaning scraper 40 and the auxiliary scraper 44 to reset, and the power cabinet 10 can achieve normal operation.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but 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.
