Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic energy storage, in particular to a photovoltaic energy storage device. Background Art

[0002] Photovoltaic energy storage device is a system that combines photovoltaic power generation and energy storage. When there is sufficient sunlight, part of the electricity generated by the photovoltaic module is directly supplied to the electrical equipment, and the other part is stored in the energy storage battery. When there is no sunlight or the power consumption is high, the energy in the energy storage battery is released to meet the power demand.

[0003] Most of the existing photovoltaic energy storage devices are distributed in the northwest and other regions with sufficient sunlight and sparse population. The large temperature difference between day and night in the northwest and other regions causes the air near the ground to cool and contract at night, forming a strong downward airflow, thereby enhancing the wind force. In addition, there is a large amount of sand in the northwest and other regions, which easily forms sandstorms. If the solar panels of the photovoltaic energy storage devices are exposed to the sandstorm environment at night, the sandstorms will easily cause the surface of the solar panels to be covered with sand and dust, reducing their lighting efficiency. In addition, the particles in the sandstorms will cause wear and corrosion on the surface of the solar panels, affecting the service life of the solar panels.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0039] Example 1: Photovoltaic energy storage device, refer to Figure 1 As shown, it includes an energy storage operation box 11, a photovoltaic panel 12, a circuit board 13, and a connecting line 14. A battery is arranged inside the energy storage operation box 11, the photovoltaic panel 12 is arranged on the energy storage operation box 11, the circuit board 13 is fixedly connected in the cavity of the energy storage operation box 11, and the connecting line 14 is inserted into the circuit board 13. The photovoltaic panel 12 converts light energy into electrical energy, and the battery stores the electrical energy in the form of chemical energy.

[0040] Reference Figures 1 to 6As shown, in order to ensure that the photovoltaic panel 12 will not be covered and worn by wind and sand at night, a large particle cleaning component is provided on the energy storage operation box 11. The large particle cleaning component is used to store the photovoltaic panel 12 in the cavity of the energy storage operation box 11 when there is no light at night, and remove the large particles of wind and sand on the photovoltaic panel 12 during the storage process. The large particle cleaning component includes two electric telescopic rods 21, and the two electric telescopic rods 21 are symmetrically fixedly connected in the cavity of the energy storage operation box 11. The side wall of the energy storage operation box 11 facing the photovoltaic panel 12 is provided with an opening. The telescopic ends of the two electric telescopic rods 21 extending outside the energy storage operation box 11 extend from the horizontal middle position of the opening, and each is fixedly connected with a connecting block 22, and the sides of the two connecting blocks 22 close to each other are each fixedly connected with a rotating motor 23, and the sides of the two connecting blocks 22 away from the electric telescopic rods 21 are each fixedly connected with a light sensor 24. The electric telescopic rods 21, the rotating motor 23, and the light sensor 24 are all existing known technologies and are not described in detail here. The combined linkage relationship of the electric telescopic rod 21, the rotating motor 23, and the light sensor 24 is as follows: the light sensor 24 is electrically connected to the controller, and the controller is electrically connected to the electric telescopic rod 21 and the rotating motor 23. Figure 2 For position reference, when it is daytime outside, when the light sensor 24 senses light, the controller receives the signal from the light sensor 24, and the controller drives the electric telescopic rod 21 and the rotating motor 23 to be energized according to the signal. When the electric telescopic rod 21 and the rotating motor 23 are energized, the telescopic end of the electric telescopic rod 21 first extends out of the opening of the energy storage operation box 11, and after the telescopic end of the electric telescopic rod 21 is fully extended, the rotating motor 23 rotates; when night comes, the light sensor 24 cannot sense light, and the controller drives the electric telescopic rod 21 and the rotating motor 23 to be de-energized according to the signal. When the electric telescopic rod 21 and the rotating motor 23 are de-energized, the rotating motor 23 first rotates clockwise, and then the energized telescopic end of the electric telescopic rod 21 contracts into the opening of the energy storage operation box 11. The telescopic ends of the two rotating motors 23 are fixedly connected to the photovoltaic panel 12 to Figure 1For position reference, a rainwater collection box 25 is fixedly connected to the right side of the top surface of the energy storage operation box 11, and a solenoid valve 26 is installed on the outer wall of the rainwater collection box 25. A horizontal water pipe 27 is fixedly connected to the solenoid valve 26. A filter plate is provided on the top surface of the rainwater collection box 25 to prevent external sand from falling into the rainwater collection box 25. The bottom of the rainwater collection box 25 is set as an inclined surface, and the lowest point of the inclined surface of the rainwater collection box 25 is close to the solenoid valve 26. Its function is to guide the rainwater in the cavity of the rainwater collection box 25 to flow to the solenoid valve 26. The rainwater collection box 25 is connected to the horizontal water pipe 27 through the electromagnetic valve 26. There is an electrical connection between the electromagnetic valve 26 and the controller of the above-mentioned light sensor 24. When the light sensor 24 cannot sense light at night, the controller receives the signal of the light sensor 24, and the controller drives the electromagnetic valve 26 to open, so that the rainwater collection box 25 and the horizontal water pipe 27 are internally connected. The horizontal water pipe 27 is fixedly connected to the top surface of the energy storage operation box 11. Leakage holes are evenly opened on the horizontal water pipe 27 toward the bottom direction of the energy storage operation box 11. The horizontal water pipe 27 is located at the top of the moving path of the electric telescopic rod 21 and the photovoltaic panel 12. Specifically: Figure 3 , Figure 4 As shown, at night, when the light sensor 24 cannot sense light, the solenoid valve 26 connects the rainwater collection box 25 and the horizontal water pipe 27, so that the rainwater inside the rainwater collection box 25 flows into the cavity of the horizontal water pipe 27 and drips to the bottom through the leakage holes evenly opened on the horizontal water pipe 27. The solenoid valve 26 is set to be able to automatically shut down at a fixed time. When the photovoltaic panel 12 completely enters the cavity of the energy storage operation box 11, the solenoid valve 26 automatically cuts off the power, so that the rainwater collection box 25 and the horizontal water pipe 27 are no longer connected. The setting of the rainwater collection box 25 can clean the photovoltaic panel 12 through rainwater without an external water source. The top surface of the energy storage operation box 11 is fixedly connected to the side close to the horizontal water pipe 27, and the side of the air outlet box 28 away from the horizontal water pipe 27 is fixedly connected to the air pump 29. The side of the air outlet box 28 away from the air pump 29 is set as an inclined air outlet. The air outlet box 28 and the solenoid valve 26 are turned on and off together to Figure 3 , Figure 4For position reference, the outlet slope of the air outlet box 28 faces the photovoltaic panel 12, and its function is to enable the airflow blown out by the air pump 29 through the air outlet box 28 to blow the sand and soil on the photovoltaic panel 12 that are easy to fall off away from the surface of the photovoltaic panel 12 before being soaked by the water flow in the horizontal water pipe 27. Moreover, since the airflow blown out by the air outlet box 28 is inclined, and the water flow out of the horizontal water pipe 27 drips vertically downward under the action of gravity, the airflow blown out by the air outlet box 28 will not affect the normal outflow of water at the bottom of the horizontal water pipe 27. The opening position of the energy storage operation box 11 is based on the telescopic end of the electric telescopic rod 21, and two scrapers 210 are fixedly connected symmetrically up and down. The material of the scraper 210 is set to hard rubber. The contact position between the two scrapers 210 is located on the moving path of the telescopic end of the electric telescopic rod 21 driving the photovoltaic panel 12 to extend and retract. There is a through hole reserved for the telescopic end of the electric telescopic rod 21 in the middle of the two scrapers 210. The function is: when the photovoltaic panel 12 and the telescopic end of the electric telescopic rod 21 are retracted into the inner cavity of the energy storage operation box 11, the photovoltaic panel 12 enters from the contact position between the two scrapers 210, lifts up and separates the two scrapers 210, and causes the two scrapers 210 to produce elastic deformation. The side where the two scrapers 210 are close to each other scrapes off the large particles of sand on the photovoltaic panel 12 and the telescopic end of the electric telescopic rod 21. When the telescopic end of the electric telescopic rod 21 is fully retracted, the photovoltaic panel 12 retracts into the cavity of the energy storage operation box 11. At this time, the side wall of the connecting block 22 connected to the light sensor extends outward and contacts the scrapers 210 at the through-holes reserved for the telescopic end of the electric telescopic rod 21 by the two scrapers 210, and seals the through-holes, so that the light sensor 24 is exposed outside the cavity of the energy storage operation box 11. The photovoltaic panel 12 and the rotating motor 23 are located in the cavity of the energy storage operation box 11, and the two scrapers 210 close to each other resume the conflict, so that the cavity of the energy storage operation box 11 is sealed, which has the following functions: The interior of the operating box 11, the photovoltaic panel 12 and the rotating motor 23 are not affected by external wind and sand, so that the light sensor 24 can always be located outside and can detect external light conditions. A cleaning plate 211 is fixedly connected to the connecting block 22 close to the rainwater collection box 25. The cleaning plate 211 is set in an L shape, and the filter plate on the top surface of the rainwater collection box 25 is located on the moving path of the cleaning plate 211. When the cleaning plate 211 moves to the position of the filter plate on the top surface of the rainwater collection box 25, the cleaning plate 211 is in contact with the filter plate on the top surface of the rainwater collection box 25, and the accumulated sand on the filter plate on the top surface of the rainwater collection box 25 is scraped off.

[0041] Reference Figures 1 to 6As shown, when night falls, the light sensor 24 detects that the brightness of the external light decreases. At this time, the photovoltaic panel 12 can no longer collect electricity through the external sunlight. At this time, the light sensor 24 drives the rotating motor 23 to rotate through the controller, so that the photovoltaic panel 12 rotates horizontally, and then the telescopic end of the electric telescopic rod 21 is opened to retract, and the solenoid valve 26 is driven to open the connection between the rainwater collection box 25 and the horizontal water pipe 27, and the air pump 29 is driven to energize and start blowing. Then, the photovoltaic panel 12 gradually enters the energy storage operation box 11 cavity in a horizontal shape. At this time, the air pump 29 obliquely discharges air to the photovoltaic panel 12 through the air outlet of the air outlet box 28, blows the sand on the surface of the photovoltaic panel 12 off the surface, and the horizontal water pipe 27 discharges water to the surface of the photovoltaic panel 12, soaking the surface of the photovoltaic panel 12, and the photovoltaic panel 12 hits the two scrapers 210, so that the two scrapers 210 separate and produce elastic deformation, so that in the process of the photovoltaic panel 12 and the electric telescopic rod 21 entering the cavity of the energy storage operation box 11, The residual sand and water stains on the surface of the photovoltaic panel 12 are scraped off until the photovoltaic panel 12 completely enters the cavity of the energy storage operation box 11. At this time, the solenoid valve 26 and the air pump 29 are powered off. At this time, the side wall of the connecting block 22 seals the through hole of the two scrapers 210 reserved for the telescopic end of the electric telescopic rod 21, and the light sensor 24 is located outside the energy storage operation box 11. The light sensor 24 continues to detect the external light conditions, and most of the sand on the surface of the photovoltaic panel 12 after the movement is cleaned. In addition, in the case of wind and sand at night, the photovoltaic panel 12 is located in the cavity of the energy storage operation box 11 and is not affected by the external wind and sand, so as to avoid the surface of the photovoltaic panel 12 being eroded and covered by wind and sand, thereby ensuring the photovoltaic collection effect of the photovoltaic panel 12. At the same time, because the side wall of the connecting block 22 seals the through hole of the two scrapers 210 reserved for the telescopic end of the electric telescopic rod 21, it plays the role of sealing the energy storage operation box 11, thereby achieving isolation from the external wind and sand environment and avoiding the entry of wind and sand into the energy storage operation box 11.

[0042] Example 2: Reference Figures 7 to 11As shown, a dry sewage discharge component is arranged inside the energy storage operation box 11, and the dry sewage discharge component is used to clean small particles of sand and soil remaining on the photovoltaic panel 12, as well as residual moisture on the photovoltaic panel 12. The dry sewage discharge component includes a latch 31, and the latch 31 is fixedly connected to the side of the photovoltaic panel 12. Two load-bearing plates 32 are symmetrically fixedly connected to the top of the inner wall of the energy storage operation box 11, and the bottom ends of the two load-bearing plates 32 are rotatably connected to a rotating shaft column 33, and a transverse bevel gear 34 is fixedly connected to the rotating shaft column 33. A cleaning cotton roller 35 is fixedly connected to the surface of the rotating shaft column 33, and the cleaning cotton roller 35 is located on the moving path of the photovoltaic panel 12. Specifically, when the photovoltaic panel 12 enters the cavity of the energy storage operation box 11, the cleaning cotton roller 35 contacts the surface of the photovoltaic panel 12 and is deformed by the contact of the photovoltaic panel 12. The material of the cleaning cotton roller 35 is set to be a sponge, and its function is: through the water absorption of the sponge and the adhesion of the sand after being soaked with water, When the photovoltaic panel 12 contacts the cleaning cotton roller 35, the cleaning cotton roller 35 absorbs the wet sand and residual moisture on the surface of the photovoltaic panel 12. A vertical rotating column 36 is rotatably connected to the top of the inner cavity of the energy storage operation box 11. A linkage gear 37 is fixedly connected to the bottom end of the vertical rotating column 36. The linkage gear 37 is meshed with the latch tooth 31. The linkage gear 37 is located on the moving path of the latch tooth 31. A vertical bevel gear 38 is fixedly connected to the middle part of the vertical rotating column 36. The vertical bevel gear 38 is meshed with the horizontal bevel gear 34. The function is: when the photovoltaic panel 12 enters the cavity of the energy storage operation box 11, the cleaning cotton roller 35 is driven to rotate and clean the surface of the photovoltaic panel 12. A dirt collecting frame 39 is fixedly connected between the two load-bearing plates 32. The dirt collecting frame 39 is located on the rotating path of the cleaning cotton roller 35. The cleaning cotton roller 35 is squeezed and matched with the dirt collecting frame 39. The bottom surface of the dirt collecting frame 39 on one side away from the vertical rotating column 36 is fixedly connected with a sewage pipe 310. Figure 1 As shown, one end of the sewage pipe 310 away from the sewage collecting frame 39 passes through the outer wall of the energy storage operation box 11, and the bottom surface of the sewage collecting frame 39 is set as an inclined surface which is higher on the side close to the transverse bevel gear 34 and lower on the side close to the sewage pipe 310. The function is to allow the wet sand and moisture cleaned by the cleaning cotton roller 35 to flow inside the sewage collecting frame 39 toward the sewage pipe 310, and be discharged to the outside of the energy storage operation box 11 through the sewage pipe 310.

[0043] Reference Figures 7 to 11As shown, when the photovoltaic panel 12 enters the cavity of the energy storage operation box 11, the latch 31 drives the linkage gear 37 to rotate, and the linkage gear 37 drives the vertical rotating column 36 to rotate. The vertical rotating column 36 rotates and drives the vertical bevel gear 38 to rotate, so that the vertical bevel gear 38 engages the horizontal bevel gear 34 to drive the rotating shaft column 33 to rotate, and then the cleaning cotton roller 35 rotates. During the rotation, the cleaning cotton roller 35 absorbs the small particles of sand and water stains remaining on the surface of the photovoltaic panel 12. Through the adsorption of the cleaning cotton roller 35 and the wetting and cleaning of water, the small particles of sand and soil remaining after the scraper 210 is scraped can be cleaned. Through the two cleaning methods of the scraper 210 and the cleaning cotton roller 35, the cleanliness of the surface of the photovoltaic panel 12 can be ensured, and the sand and soil can be prevented from interfering with the performance of the photovoltaic panel 12 and the lighting effect.

[0044] Reference Figures 7 to 11 As shown, during the rotation of the cleaning cotton roller 35, the sand adhered to the surface of the cleaning cotton roller 35 and the moisture absorbed inside the cleaning cotton roller 35 are squeezed and collected into the inside of the cleaning cotton roller 39 by the dirt collecting frame 39, and discharged to the outside of the energy storage operation box 11 through the inclined surface of the dirt collecting frame 39, so that during the process of the cleaning cotton roller 35 cleaning the photovoltaic panel 12, the outer surface of the cleaning cotton roller 35 in contact with the photovoltaic panel 12 is always clean and dry, thereby ensuring the cleaning effect of the cleaning cotton roller 35.

[0045] Embodiment 3: When the existing photovoltaic energy storage device is set up in the northwest and other areas with sufficient sunlight, the sunlight is sufficient during the day, the photovoltaic energy storage device is in a high-temperature working state for a long time, and the internal line expands due to the heat. At night, the temperature drops sharply and the line shrinks sharply. This repeated expansion and contraction will gradually reduce the tightness of the line connection parts, thereby causing the line to loosen. In addition, strong winds at night in the northwest and other areas will cause the photovoltaic energy storage device to vibrate. Long-term vibration will also cause the line connection parts to gradually loosen, and then a line pressure stabilization component is set.

[0046] Reference Figure 12 to Figure 13As shown, a line pressure stabilization component is provided inside the energy storage operation box 11. The line pressure stabilization component is used to press the connection line 14 when the photovoltaic panel 12 is received into the inner cavity of the energy storage operation box 11. The line pressure stabilization component includes two support side plates 41. The two support side plates 41 are symmetrically fixedly connected to the circuit board 13. A movable groove 42 is provided on each of the two support side plates 41. A slide plate 43 is slidably connected inside each of the two movable grooves 42. The shape of the movable groove 42 is set to be L-shaped. The bottom end of the movable groove 42 is located in the same horizontal plane as the connection line 14. A connecting rib 44 is fixedly connected between the sides of the two slide plates 43. A pressure plate 45 is fixedly connected to the surface of the connecting rib 44. The material of the pressure plate 45 is set to be rubber. The function is: the rubber material of the pressure plate 45 can provide flexible resistance for the connection line 14. Two side support plates 46 are symmetrically fixedly connected to the side wall of the inner cavity of the energy storage operation box 11. A top slide bar 47 is slidably connected to each of the two side support plates 46. The top ends of the two top slide bars 47 are commonly fixedly connected to a trigger plate 48. Fig.13 For position reference, the side of the trigger plate 48 close to the photovoltaic panel 12 is set to be inclined, and the inclined surface of the trigger plate 48 is located on the moving path of the photovoltaic panel 12. When the photovoltaic panel 12 enters the inner cavity of the energy storage operation box 11, the photovoltaic panel 12 will resist the inclined surface of the trigger plate 48 and apply a downward pressure force to the trigger plate 48. A second spring 49 is sleeved on the surface of each of the two top sliding rods 47, and the bottom ends of the two second springs 49 are fixedly connected to the adjacent side support plates 46, and the top ends of the two second springs 49 are fixedly connected to the trigger plate 48. The bottom ends of the two top sliding rods 47 are each fixedly connected to a linkage rod 410, and the two linkage rods 410 are fixedly connected to the adjacent slide plates 43. The material of the linkage rod 410 is set to elastic plastic, and its function is: when the slide plate 43 slides in the L-shaped interior of the moving groove 42, the elastic deformation of the elastic plastic of the linkage rod 410 can facilitate the slide plate 43 to slide to the bottom end of the moving groove 42, and at the same time, when the photovoltaic panel 12 no longer conflicts with the trigger plate 48, the elastic force of the linkage rod 410 can help the slide plate 43 to reset.

[0047] Reference Figure 12 to Figure 13As shown, when the photovoltaic panel 12 enters the cavity of the energy storage operation box 11, the photovoltaic panel 12 contacts and squeezes the trigger plate 48, so that the top slide bar 47 slides downward inside the side support plate 46 and compresses the second spring 49, so that the linkage rod 410 drives the slide plate 43 to slide downward inside the moving groove 42. When the slide plate 43 slides, it can drive the connecting rib 44 and the pressure plate 45 to move synchronously. When the slide plate 43 slides to the bottom of the moving groove 42, the linkage rod 410 is elastically deformed, and the pressure plate 45 contacts the connecting line 14 at this time, and continues to slide with the slide plate 43 in the horizontal section inside the moving groove 42. The pressure plate 45 pushes the connecting wire 14 toward the circuit board 13. At this time, due to the elasticity of the pressure plate 45, it can provide thrust when the connecting wire 14 is loose, and when the connecting wire 14 and the circuit board 13 are firmly plugged in, it will not cause excessive extrusion pressure, resulting in damage to the connecting wire 14. Since the photovoltaic panel 12 is stored in the cavity of the energy storage operation box 11 every night, the pressure plate 45 can press the connecting wire 14 once a day to strengthen the connection effect between the connecting wire 14 and the circuit board 13, thereby avoiding damage to the operation of the photovoltaic energy storage device due to loose connection between the circuit board 13 and the connecting wire 14.

[0048] When the photovoltaic panel 12 is separated from the energy storage operation box 11 , the photovoltaic panel 12 no longer contacts the trigger plate 48 , and the line pressure stabilizing assembly is reset under the elastic extension of the second spring 49 and the linkage rod 410 .
