Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] Example:

[0033] See also Figure 1-Figure 7 The present invention provides a technical solution: an outdoor photovoltaic energy storage cabinet, comprising:

[0034] The power storage cabinet 1 comprises a cabinet body 11, a control module 12 and a battery module 13 are respectively arranged inside the cabinet body 11, and the cabinet body 11 is connected to a cabinet door 14 by hinge rotation;

[0035] The heat dissipation cabinet 2 adopts a single-sided opening design, the opening end of the heat dissipation cabinet 2 is fixedly connected to the outer surface of the cabinet door 14, the outer surface of the heat dissipation cabinet 2 is fixedly connected with a ventilation plate 21, and the heat dissipation cabinet 2 is provided with a dust cleaning part 22 for cleaning dust on the surface of the ventilation plate 21;

[0036] Among them, the cleaning part 22 includes a brush plate 221 adapted to the ventilation plate 21, the side of the brush plate 221 away from the ventilation plate 21 is fixedly connected with a swing frame 222, and telescopic parts 23 are symmetrically arranged on both sides of the swing frame 222, and the side of the brush plate 221 away from the ventilation plate 21 is fixedly connected with a fixed column 223, the circumferential outer surface of the fixed column 223 is sleeved with a compression spring group 224 connected to the outer surface of the brush plate 221, and the end of the compression spring group 224 away from the brush plate 221 is provided with an extrusion plate 225 sliding with the circumferential outer surface of the fixed column 223, and the end of the fixed column 223 away from the extrusion plate 225 is fixedly connected with a connecting rod 226.

[0037] The telescopic member 23 includes an inner tube 231, which is rotatably connected to the side of the swing frame 222 through a rotating shaft, and the outer surface of the inner tube 231 is slidably connected to the outer tube 233, and the end of the inner tube 231 away from the swing frame 222 is fixedly connected to a limit ring 232 that slides with the inner wall of the outer tube 233, and the outer surface of the circumference of the inner tube 231 is sleeved with a spring 234 connected to the outer end of the limit ring 232. The telescopic member 23 can ensure that the dust cleaning part 22 always maintains a horizontal state with the ventilation plate 21 during the displacement process.

[0038] One end of the outer tube 233 away from the swing frame 222 is slidably connected to the slide rod 24 through a sliding hole. The top of the slide rod 24 is fixedly connected to the top of the inner wall of the heat dissipation cabinet 2. The other end of the slide rod 24 is provided with a buffer 241. The end of the buffer 241 away from the slide rod 24 is provided with a limit column 242 fixedly connected to the bottom of the inner wall of the heat dissipation cabinet 2. The buffer 241 can effectively buffer the impact caused by the descent of the cleaning part 22 and cause it to slightly move up and down.

[0039] A flapping mechanism 25 is also provided inside the heat dissipation cabinet 2, and the flapping mechanism 25 includes a fixed rod 251, the outer end of the fixed rod 251 is fixedly connected to the inside of the connecting rod 226, two connecting rods 226 are provided and symmetrically distributed with the fixed rod 251 as the center, and the circumferential outer surface of the fixed rod 251 is rotatably connected to an eccentric wheel 252, and a rack rod 253 is provided on the side of the eccentric wheel 252 away from the brush plate 221, and both sides of the rack of the rack rod 253 are provided with a limiting sleeve 254. The eccentric wheel 252 cooperates with the rack rod 253 to complete the intermittent flapping of the ventilation plate 21.

[0040] The outer circumferential surface of the fixing rod 251 is sleeved with a torsion spring 255 connected to the end surface of the eccentric wheel 252, and the end of the torsion spring 255 away from the eccentric wheel 252 is provided with a connecting ring 256 connected to the outer circumferential surface of the fixing rod 251. The torsion spring 255 is locked during the descent of the dust cleaning part 22, and quickly releases energy and rotates quickly when it is separated from the rack.

[0041] A plurality of groups of teeth 2521 are evenly distributed on the outer circumferential surface of the eccentric wheel 252 , and the teeth 2521 mesh with the racks of the rack rod 253 .

[0042] The swing frame 222 is installed with a hanging member 26 via a hanging ring 261 arranged on the upper surface thereof, and the hanging member 26 is connected to an external traction device. A detachable dust box 27 is arranged below the heat dissipation cabinet 2 .

[0043] refer to Figure 1-7 In the prior art, the battery pack in the photovoltaic energy storage cabinet needs to release heat through the vents to work, and the photovoltaic energy storage cabinet is usually installed outdoors, which is often accompanied by natural factors such as wind, sand, and dust. After being exposed to such an environment for a long time, the vents will inevitably accumulate a lot of dust and impurities. This will hinder the normal discharge of heat, causing the internal temperature of the equipment to rise, which in turn affects the normal operation and efficiency of the photovoltaic energy storage cabinet.

[0044] In order to overcome the above-mentioned defects, the present invention designs an outdoor photovoltaic energy storage cabinet, which can realize automatic dust cleaning of the ventilation holes of the outdoor photovoltaic energy storage cabinet without manual auxiliary cleaning, thereby avoiding the reduction in efficiency caused by high temperature inside the energy storage cabinet due to blockage of the ventilation holes.

[0045] In actual applications, the photovoltaic energy storage cabinet is located in an outdoor working environment. A seal is provided between the power storage cabinet 1 and the cabinet door 14, which can well protect the sealing performance inside the cabinet 11 and ensure that the control module 12 and the battery module 13 are not affected by natural factors such as rain and dust. However, since the battery module 13 will continuously emit heat energy during operation, it is necessary to rely on the ventilation plate 21 for internal and external gas exchange and heat dissipation, which is easy to accumulate dust. The dust cleaning part 22 is placed inside the heat dissipation cabinet 2. When the energy storage cabinet is in working state, the hoisting part 26 pulls the dust cleaning part 22 to the top of the inner wall of the heat dissipation cabinet 2. The slide bar 24 is vertically arranged inside the heat dissipation cabinet 2, and the edge of the outer tube 233 is slidably connected to the slide bar 24. The outer tube 233 cooperates with the inner tube 231 and the spring 234. The two sets of telescopic parts 23 are on the left and right sides of the swing frame 222, so that the brush plate 221 always maintains a horizontal state with the ventilation plate 21. The ventilation plate 21 is adjacent to the battery module 13 , which is beneficial for directly exchanging the heat dissipated by the battery module 13 with the internal and external gases at the ventilation plate 21 , thereby facilitating the control of the internal temperature.

[0046] The process of the dust cleaning section 22 descending:

[0047] After the energy storage cabinet is powered off, the traction device installed on the top of the inner wall of the heat dissipation cabinet 2 loses its power source (the control module 12 will automatically power off according to the changes in power demand and the charging status of the energy storage system), and the hanging part 26 is connected to the hanging ring 261 on the upper surface of the swing frame 222 through a rope. Under the action of gravity, one end of the outer tube 233 drives the cleaning part 22 as a whole to slide downward on the surface of the slide rod 24.

[0048] The thickness of the eccentric wheel 252 is equal to the distance between the two limiting sleeves 254. In the initial state, the eccentric wheel 252 is located in the middle of the fixing rod 251. As the whole descends, the eccentric wheel 252 first moves between the two limiting sleeves 254, and the teeth 2521 on the outer surface of the circumference of the eccentric wheel 252 mesh with the rack at the rack rod 253. Under the gravity potential energy of the descent, the teeth 2521 and the rack in the middle of the rack rod 253 continue to mesh and rotate, and the teeth 2521 on the side of the eccentric wheel 252 closer to the axis rotate to mesh with the rack.

[0049] At this time, the side of the eccentric wheel 252 with a larger eccentricity rotates to the surface of the extrusion plate 225, and the extrusion plate 225 is squeezed into the swing frame 222. At the same time, because the rack is connected to the tooth surface of the tooth 2521, the axis of the eccentric wheel 252 moves to the side away from the rack rod 253, and the fixed rod 251 correspondingly drives the connecting rod 226 to push the side of the ventilation plate 21, and the swing frame 222 and the brush plate 221 are also synchronously pushed to the side of the ventilation plate 21. At this time, the inner tube 231 is rotatably connected to the swing frame 222, and the spring 234 on the outer surface of the inner tube 231 is compressed as the inner tube 231 and the outer tube 233 move away from each other.

[0050] When the eccentric wheel 252 continues to rotate, the teeth 2521 on the side with a larger eccentric distance from the axis rotate to mesh with the rack, and the axis of the eccentric wheel 252 deviates to one side of the rack rod 253. At this time, the spring 234 between the brush plate 221 and the squeeze plate 225 returns to the expanded state, and the squeeze plate 225 is lifted to fit the surface of the eccentric wheel 252. The spring 234 in the telescopic member 23 returns to the expanded state, and the swing frame 222, the fixed column 223 and the brush plate 221 rebound to the side of the rack rod 253.

[0051] Torsion springs 255 are provided at the left and right ends of the eccentric wheel 252. The other end of the torsion spring 255 is connected to the limit sleeve 254. The limit sleeve 254 is fixedly connected to the fixed rod 251. The torsion spring 255 is gradually tightened after the eccentric wheel 252 is engaged with the rack rod 253 and rotates several circles. At this time, the eccentric wheel 252 stores rotational potential energy, and the cleaning part 22 is close to the ventilation plate 21.

[0052] As the dust cleaning part 22 continues to descend, the outer tube 233 slides and descends on the outer surface of the slide rod 24, and the eccentric wheel 252 is separated from the rack and the limiting sleeve 254 in the middle of the rack rod 253. At this time, the teeth 2521 lose the meshing limit with the rack, and the lower end of the slide rod 24 extends into the limiting column 242. The buffer 241 sleeved on the outer surface of the limiting column 242 is conducive to providing elastic protection for the descent of the dust cleaning part 22, and under the action of elasticity, the dust cleaning part 22 touches the bottom and then moves up and down until it returns to a stable state, and the brush plate 221 slides back and forth on the surface of the ventilation plate 21 (the brush on the surface of the brush plate 221 can clean the dust accumulated in the fine gaps inside the ventilation plate 21). At the same time, under the action of the torsion spring 255, the axis of the eccentric wheel 252 rotates rapidly around the fixed rod 251. Under the action of the centrifugal rotation and inertia of the eccentric wheel 252, the cleaning part 22 beats back and forth, and the brush on the surface of the brush plate 221 passes back and forth through the ventilation holes on the surface of the ventilation plate 21, so as to knock off most of the dust. At the same time, the torsion spring 255 releases the potential energy of rotation, and squeezes the extrusion plate 225 back and forth to one side of the swing frame 222. The extrusion plate 225 is fitted and slid with the inner wall of the swing frame 222 on all sides. Since the extrusion plate 225 and the swing frame 222 are both solid designs, during the swinging and extruding process, the generated airflow will flow out into the gap on the surface of the brush plate 221, and the dust knocked off by the brush plate 221 and the swing frame 222 will be sprayed out. After swinging back and forth, the cleaning part 22 will be in a stationary state.

[0053] The rising process of the dust cleaning part 22:

[0054] When the energy storage cabinet restores the power system, the traction unit will lift the hoisting part 26, and the rope will pull the lifting ring 261 to pull the cleaning unit 22 upward. The eccentric wheel 252 is in the middle of the fixed rod 251. As it rises, the eccentric wheel 252 is placed in the middle of the limit sleeves 254 on both sides. During the rise, the teeth 2521 mesh with the rack and move upward. As the axis of the eccentric wheel 252 moves, the swing frame 222 swings back and forth, and the extrusion plate 225 moves close to the brush plate 221, spraying excess dust to the outside of the ventilation plate 21, and the remaining dust that has not been sprayed falls into the dust box 27. After accumulating to a certain extent, it can be disassembled and poured out. The cleaning unit 22 rises steadily to the top and waits for the next power failure to automatically descend for cleaning.

[0055] In summary, the cleaning section 22 has the following advantages during the lifting process:

[0056] Advantage 1: The dust cleaning part 22 is provided with a brush plate 221 adapted to the ventilation plate 21, and a compression spring group 224 and a squeeze plate 225 are provided on one side of the brush plate 221. By moving the fixed column 223, the brush on the surface of the brush plate 221 can contact the vent of the ventilation plate 21, and the back and forth displacement can effectively scrape and remove dust and impurities on the ventilation plate 21. It can ensure that the heat inside the device can be dissipated in time, avoiding performance degradation or failure caused by overheating of the battery module 13.

[0057] Advantage two, the teeth 2521 on the eccentric wheel 252 mesh with the rack rod 253, so that the axis of the eccentric wheel 252 is offset, and the connecting rod 226 and the fixed column 223 are displaced accordingly, thereby driving the brush on the brush plate 221 to beat the dust inside the ventilation plate 21. The design of the eccentric wheel 252 makes the beating effect intermittent. The intermittent beating method can loosen and shake off the dust or lumps, thereby preventing dust from adhering to the surface of objects for a long time to form stubborn dirt that is difficult to remove.

[0058] Advantage three: during the rotation of the eccentric wheel 252, the extrusion plate 225 is squeezed into the internal space surrounded by the swing frame 222, wherein the extrusion plate 225 moves in close contact with the fixed column 223, and the outer periphery of the extrusion plate 225 slides in close contact with the inner wall of the swing frame 222. The distance between the extrusion plate 225 and the brush plate 221 in the swing frame 222 becomes smaller, and during the swing extrusion process, the generated airflow flows out through the gap on the surface of the brush plate 221, and the dust remaining on the brush plate 221 and the swing frame 222 due to the beating can be sprayed out.

[0059] Advantage 4: Torsion springs 255 are arranged at both ends of the eccentric wheel 252. When the teeth 2521 and the rack rod 253 engage with each other and rotate, the torsion spring 255 will gradually tighten, thereby accumulating energy. When the teeth 2521 are separated from the rack rod 253, the eccentric wheel 252 will release the accumulated rotational potential energy and rotate at a high speed, thereby driving the dust caused by the brush plate 221 in the dust cleaning part 22 beating the heat dissipation cabinet 2 to scatter.

[0060] Advantage 5: Through the intelligent power-off command of the control module 12, the hanging part 26 can automatically respond and drive the dust cleaning part 22 to move down to automatically clean the ventilation plate 21. Once the cleaning is completed and the power-on signal is received, the hanging part 26 will start immediately and smoothly lift the dust cleaning part 22 back to its initial position. After the dust cleaning part 22 is folded, it will not affect the heat dissipation of the battery module 13. No manual on-site operation is required throughout the process, which significantly improves the automation level of the overall system.

[0061] Advantage 6: The slide bar 24 penetrates into the inside of the limit column 242, and a buffer 241 is provided on the upper surface of the limit column 242. When the dust cleaning part 22 falls, the buffer 241 effectively slows down the movement, and the dust cleaning part 22 will slightly move up and down under the effect of buffering until it is stable. At this time, the brush plate 221 is closely attached to the ventilation plate 21, and through delicate friction, the dust accumulated inside the ventilation port and in the tiny gaps is deeply cleaned to ensure the cleaning effect.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
