Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage technology, specifically to a photovoltaic energy storage device. Background Technology

[0002] Photovoltaic energy storage is a core technology system that combines photovoltaic power generation systems with energy storage systems. Through the coordinated process of "photovoltaic power generation → energy storage → on-demand release", it solves the pain points of "intermittency, volatility and day-night imbalance" of photovoltaic power generation. It is widely used in distributed homes, industrial and commercial parks, large-scale photovoltaic power plants and microgrids.

[0003] Existing photovoltaic energy storage equipment often uses fixed brackets to support photovoltaic panels, which are then used in conjunction with energy storage boxes. During use, it has been found that traditional photovoltaic energy storage equipment has poor wind resistance, and photovoltaic panels are easily affected by wind and fall off the brackets. After long-term use, impurities are easily adhered to the surface of the photovoltaic panels, which reduces their energy conversion efficiency. Moreover, when photovoltaic equipment is used outdoors, the equipment temperature needs to be controlled in order to cope with different environments. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-10 A photovoltaic energy storage device includes an energy storage box 1, and further includes:

[0037] A cleaning assembly includes a cover 2, a driver, a screw 3, an output component, and a liquid supply component. The cover 2 is mounted on the energy storage tank 1. A drive groove is located below the cover 2. The driver is located at the center below the cover 2. The driver includes a motor 4, a first cover 5, a first worm gear 6, and a first worm 7. The first cover 5 is located at the center below the cover 2. The first worm 7 and two sets of first worm gears 6 are disposed inside the first cover 5. The first worm 7 meshes with the two sets of first worm gears 6. The first worm 7 passes through the first cover 5 and the cover 2 and is connected to the motor 4. Screws 3 are rotatably connected to the sidewalls of the drive groove on both the left and right sides of the center of the first worm gear 6. Two sets of symmetrically arranged output components are also provided below the cover 2. The front and rear sides of the corresponding output components are connected to the corresponding screws 3. Cleaning holes adapted to the output components are also provided on the left and right sides of the cover 2. A liquid supply component connected to the input end of the output components is provided on the energy storage tank 1.

[0038] A photovoltaic module, comprising a photovoltaic panel 8, a second cover 9, a second worm gear 10, a second worm 11, and a rotating shaft 12. The second cover 9 is symmetrically arranged at the front and rear ends on both sides of the housing cover 2. The second worm gear 10 and the second worm 11 are disposed inside the second cover 9, meshing with each other. The corresponding second worm 11 passes through the second cover 9 and the housing cover 2 and is connected to a corresponding screw 3. The rotating shaft 12 is symmetrically arranged on both sides of the housing cover 2. The front and rear ends of the rotating shaft 12 pass through the corresponding second cover 9 and are centrally connected to the second worm gear 10. The photovoltaic panel 8 is disposed on the rotating shaft 12, which is located below the output component.

[0039] A heat dissipation component is also provided on the energy storage box 1.

[0040] In the initial state, the equipment is not in operation for photovoltaic power generation. The core objective is to "reduce the impact of the external environment (such as wind and low temperature) and protect the components to standby". The photovoltaic panel 8 is in a vertical state (parallel to the side of the energy storage box 1) through the rotating shaft 12. At this time, the wind resistance area of ​​the photovoltaic panel 8 is the smallest. In this state, the worm gear transmission of the second worm wheel 10 is in "self-locking": because there is no driving force of the screw 3, the second worm 11 is stationary, the meshing second worm wheel 10 cannot rotate in the opposite direction, the angle of the rotating shaft 12 and the photovoltaic panel 8 is fixed, so as to avoid the photovoltaic panel 8 swaying in the wind. The protective pads 26 on the left and right sides of the energy storage box 1 are in close contact with the inner side of the photovoltaic panel 8, which not only buffers the rigid collision between the photovoltaic panel 8 and the energy storage box 1, but also fills the gap to reduce the entry of wind and sand.

[0041] The cleaning components are in the initial "ready to be cleaned" position;

[0042] The driver (motor 4) is not started, the first worm gear 6 is stationary, the screw 3 is kept in the initial position, and the two sets of output components extend outward from the cleaning holes on the left and right sides of the box cover 2. The liquid supply component is connected to an external water supply device, which can send liquid into the output component. Then the output end of the output component sprays cleaning liquid to clean the photovoltaic panel 8.

[0043] The heat dissipation components were not activated at this time;

[0044] In this embodiment, the output component includes a diversion pipe 13, a first connecting pipe 14, a hose 15, and a slide plate 16. The slide plate 16 is T-shaped, with one end of the slide plate 16 adapted to the cleaning hole, and the front and rear sides of the other end of the slide plate 16 threadedly connected to corresponding screws 3. The diversion pipe 13 is embedded in the slide plate 16, and an output hole adapted to the output end of the diversion pipe 13 is provided below the slide plate 16. One end of the first connecting pipe 14 is connected to the input end of the diversion pipe 13, and the other end of the first connecting pipe 14 protrudes from the slide plate 16 and is connected to one end of the hose 15. The liquid supply component... The device includes a mounting plate 17, a liquid supply pump 18, and a second connecting pipe 19. The energy storage box 1 is provided with a mounting cavity with an upper opening. The mounting plate 17 is symmetrically arranged on the left and right ends of the rear side of the energy storage box 1. The liquid supply pump 18 is provided on the mounting plate 17. The second connecting pipe 19 is symmetrically arranged on the left and right sides of the mounting cavity. One end of the corresponding second connecting pipe 19 is connected to one end of the corresponding hose 15. The other end of the second connecting pipe 19 passes through the energy storage box 1 and is connected to the liquid supply pump 18. An auxiliary frame 20 for limiting the second connecting pipe 19 is also provided in the energy storage box 1.

[0045] Mounting plate 17 provides stable support for liquid supply pump 18. Liquid supply pump 18 is connected to an external liquid supply device to send liquid into second connecting pipe 19. Then the liquid enters first connecting pipe 14 through hose 15 and finally exits from diversion pipe 13 to clean photovoltaic panel 8. The output end of diversion pipe 13 is inclined to stably clean photovoltaic panel 8. Auxiliary components ensure the stability of second connecting pipe 19. After cleaning, the equipment switches to "operation state".

[0046] If it is inconvenient to equip an outdoor liquid supply device, a water tank can be installed inside the installation cavity. The water tank can be connected to the liquid supply pump 18 to provide cleaning fluid.

[0047] The driver motor 4 of the cleaning component is started. The motor 4 drives the first worm 7 to rotate. The first worm 7 meshes with two sets of first worm wheels 6 and rotates synchronously, driving the screws 3 on the left and right sides (rotatably connected to the side wall of the drive groove) to rotate. When the screws 3 rotate, on the one hand, they drive the output part (slide plate 16) of the cleaning component to retract into the box cover 2 (to avoid blocking the photovoltaic panel 8). On the other hand, they drive the second worm 11 of the photovoltaic component (connected to the screw 3) to rotate synchronously. The second worm 11 meshes with the second worm wheel 10 and drives the rotating shaft 12 (through the second cover 9) to rotate. The photovoltaic panel 8 rotates with the rotating shaft 12 to adjust the angle, ensuring the receiving area of ​​the photovoltaic panel 8.

[0048] After the angle adjustment is completed, the motor 4 stops, and the first and second worm gears 10 are locked due to "reverse self-locking". The angle of the photovoltaic panel 8 remains stable and will not shift due to wind or vibration.

[0049] During the rotation of screw 3, the output component is simultaneously retracted: slide plate 16 (T-shaped structure) moves along the cleaning hole into the box cover 2 as screw 3 rotates until slide plate 16 is completely retracted into the drive groove (flush with the inside of box cover 2). The cleaning hole is closed by slide plate 16. Diverter pipe 13 and first connecting pipe 14 are retracted along with slide plate 16. Flexible hose 15 can be folded and stored in the installation cavity due to its flexibility (auxiliary frame 20 limits the pipe to prevent tangling). At this time, the output component does not block the photovoltaic panel 8 at all, ensuring unobstructed light. Flexible hose 15 does not affect the battery assembly in the installation cavity.

[0050] Depending on the requirements, photovoltaic inverters and other photovoltaic equipment can be installed in the mounting cavity or hung on the energy storage box 1;

[0051] In operation, the heat dissipation component needs to be activated for heat dissipation. In this embodiment, the heat dissipation component includes a heat dissipation frame 21, a heat dissipation fan 22, and a protective frame 23. The energy storage box 1 has symmetrical heat dissipation holes at both ends on the front and rear sides. The heat dissipation frame 21 is embedded in the heat dissipation holes. The heat dissipation fan 22 is installed inside the heat dissipation frame 21. The heat dissipation frame 21 protrudes from the energy storage box 1 and is also provided with a protective frame 23. The heat dissipation fan 22 of the heat dissipation component is activated synchronously to exhaust the hot air (such as the heat generated by the photovoltaic inverter and battery charging) in the energy storage box 1 to the outside, while simultaneously drawing in external cold air to form convection.

[0052] After the photovoltaic panel 8 is unfolded, it absorbs solar energy and converts it into direct current, which is then inverted into alternating current by the inverter.

[0053] Some electrical energy is directly supplied to loads (such as household appliances and industrial and commercial equipment).

[0054] Excess electrical energy is stored in the battery pack inside the energy storage box 1 via the energy storage converter (PCS);

[0055] If there is insufficient sunlight (such as on a cloudy day), the energy storage battery releases electrical energy to supplement it, realizing a closed loop of "generation-storage-use" and solving the pain point of intermittent photovoltaic power generation;

[0056] In this embodiment, protective frames 24 are symmetrically arranged at the left and right ends of the front and rear sides of the energy storage box 1. The protective frames 24 are arranged below the first cover 5. The first cover 5 is provided with bolts 25 that are connected to the protective frames 24. The bolts 25 facilitate the connection between the box cover 2 with the first cover 5 and the energy storage box 1 with the protective frames 24. The side wall of the protective frame 24 protrudes from the photovoltaic panel 8, providing good anti-collision protection for the photovoltaic panel 8 in the vertical state.

[0057] When encountering strong winds, rain, or sunset, the equipment automatically switches to "reset state". If it is in operation, the driver motor 4 is immediately started, driving the screw 3 to rotate in the opposite direction, which drives the photovoltaic panel 8 to quickly reset from the power generation angle to the vertical state, reducing the wind resistance area. The output component protrudes from the cleaning hole and the heat dissipation component is turned off.

[0058] In actual use, when the device switches from energy storage to energy release, no additional heat dissipation is needed. At this time, the heat dissipation holes need to be sealed to provide dust protection for the device. Therefore, adjusting components for sealing the heat dissipation holes are provided on the front and rear sides of the mounting cavity. These adjusting components include guide rods 27, guide plates 28, and sealing components. Guide rods 27 are arranged vertically on the front and rear sides of the mounting cavity, and two sets of symmetrically arranged guide plates 28 are provided on the corresponding vertically arranged guide rods 27. The guide plates 28 are slidably connected to the guide rods 27. A sealing component is provided on the side of the guide plate 28 closest to the corresponding heat dissipation hole. A notch is also provided above the guide plate 28, and a plug block 29 that inserts into the corresponding notch is provided below the sliding plate 16. The sealing component includes a sealing plate 30, elastic elements, and arc-shaped blocks 33. Elastic elements connected to the guide plates 28 are provided at the four corners of the sealing plate 30. The elastic elements include springs 31 and telescopic rods 32. 2. The spring 31 is sleeved on the telescopic rod 32. Both ends of the spring 31 and the telescopic rod 32 are connected to the guide plate 28 and the sealing plate 30, respectively. The sealing plate 30 has a rounded edge near the heat dissipation hole. The part of the sealing plate 30 that inserts into the heat dissipation hole is also provided with an arc-shaped block 33. During assembly, the insert 29 under the slide plate 16 is inserted into the notch of the guide plate 28. After the insert 29 is inserted into the notch, it moves with the slide plate 16 and pushes the guide plate 28 to slide along the guide rod 27. The sealing component completes the opening and closing of the heat dissipation hole. When the equipment is in standby mode, the spring 31 and the telescopic rod 32 are in the extended state, and the rounded edge of the sealing plate 30 abuts against the heat dissipation hole. When the equipment is in operation mode, the insert 29 drives the guide plate 28 to move. The rounded edge and the arc-shaped block 33 that contact the edge of the heat dissipation hole push the sealing plate 30 to squeeze the elastic component. The arc-shaped block 33 contacts the inner wall of the mounting cavity, reducing the contact between the sealing component and the inner wall of the mounting cavity and ensuring its operational stability.

[0059] The heat dissipation holes, together with the heat dissipation components, constitute an active heat dissipation device, which aims to accelerate heat dissipation and ensure the stability of equipment operation. Depending on the needs, auxiliary holes with dustproof nets can be added to the front and rear sides of the energy storage box 1 to ensure the heat dissipation needs of the equipment when no additional heat dissipation is required.

[0060] In this embodiment, support members 34 are also provided at the four corners below the energy storage box 1. Depending on the requirements, the support members 34 can be fixed feet or a structure of universal wheels and brakes, so that the equipment can be moved to a designated position and then fixed.

[0061] In this embodiment, handles 35 are symmetrically provided on both sides above the lid 2 to facilitate lifting the lid 2.
