[0001] The present invention relates to the field of photovoltaic technology, and in particular to a household photovoltaic energy storage device and an energy storage method thereof. Background Art

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

[0003] Photovoltaic power generation, as one of the many ways to utilize solar energy resources, has been widely used in people's lives today. In order to improve power generation efficiency, solar panels are generally fully exposed to outdoor sunlight to convert more solar energy into electricity for use. However, outdoor air flow drives the movement of dust particles. When wind blows across the surface of the solar panel, dust is easily carried by the airflow and deposited on its surface, blocking the sunlight, resulting in a reduction in the intensity of light reaching the solar cell, seriously affecting power generation efficiency.

A dust removal water tank 11 for absorbing dust is fixedly installed on the outer wall of one side of the installation box 1, and an L-shaped exhaust pipe is provided on the side wall of the dust removal water tank 11, and one end of the L-shaped exhaust pipe is facing downward to prevent the cleaned dust and garbage from falling into the L-shaped exhaust pipe. An L-shaped hard pipe 10 is fixedly installed in the dust removal water tank 11, and a corrugated connecting pipe 9 is fixedly installed on the end of the L-shaped hard pipe 10 away from the dust removal water tank 11, and the other end of the corrugated connecting pipe 9 An L-shaped connecting tube 15 is fixedly installed at one end, and the other end of the L-shaped connecting tube 15 extends into the negative pressure cavity 14. The reciprocating screw 6 rotates to drive the long rod 12, the movable plate 7, and the moving gear 18 to rotate. The rotation of the moving gear 18 drives the slave gear 20, the cross bar 19, the first bevel gear 22, and the second bevel gear 23 to rotate, and finally drives the fan blades 21 to rotate to generate an upward wind force, so that a negative pressure is formed in the negative pressure cavity 14, and then the cleaned dust is adsorbed into the adsorption cavity 25, and finally transported to the dust removal water tank 11 through the connecting port 16, the annular cavity 24, the negative pressure cavity 14, the L-shaped connecting tube 15, the corrugated connecting tube 9, the L-shaped hard tube 10 and the fan blades 21 to contact with water to adsorb the dust.

[0040] In order to clean out the solid impurities stuck in the adsorption port 26 and prevent the adsorption port 26 from being blocked, the dredging mechanism includes two wire rods 27 and two fixed rods 31 fixedly installed in the adsorption cavity 25, and an adsorption plate 28 is slidably installed on the two wire rods 27. A plurality of connecting transverse plates 30 corresponding to the adsorption port 26 are fixedly installed at the bottom of the adsorption plate 28. A dredging rod 29 for dredging the adsorption port 26 is fixedly installed at the bottom of the plurality of connecting transverse plates 30. A limited baffle 32 is fixedly installed at the bottom of the two fixed rods 31. A slidable adsorption plate 28 is slidably installed on the two fixed rods 31. There are vertical plates 33, winding rods 34 are rotatably installed on the two vertical plates 33, and the two winding rods 34 are respectively provided with torsion springs 39 for storing force. In order to improve the service life of the torsion springs 39, the surfaces of the two torsion springs 39 are tinned. One end of the two torsion springs 39 is fixedly connected to the two vertical plates 33, and the other ends of the two torsion springs 39 are respectively fixedly connected to the circular plates 36 fixedly sleeved on the winding rods 34. The winding rods 34 are fixedly sleeved with a cam 35 for continuously impacting the adsorption plate 28. The winding rod 34 is wrapped with two pull ropes 37, and the bottom ends of the two pull ropes 37 are respectively fixedly installed with driving The adsorption ball 38 rotates the winding rod 34. When the rotating motor 8 works and negative pressure is formed in the negative pressure cavity 14, the adsorption ball 38 and the adsorption plate 28 move upward. Under the action of continuous negative pressure, the adsorption ball 38 is always subjected to upward suction, and finally the pull rope 37 also moves upward and drives the winding rod 34 to rotate through friction. The rotation of the winding rod 34 changes the torsion spring 39 from a free state to a stressed state. When the rotating motor 8 is turned off, the fan blades 21 no longer rotate to generate wind force, and there is no negative pressure in the negative pressure cavity 14. Under the action of gravity, the dredging rod 29 will directly fall to the adsorption port 26 and the solid state. The adsorption ball 38 is no longer affected by the negative pressure and no longer maintains the upward movement trend, so that the winding rod 34 and the torsion spring 39 are no longer subjected to the upward pulling force of the adsorption ball 38. The torsion spring 39 is restored from the stressed state to the original free state to drive the winding rod 34 to rotate. The rotation of the winding rod 34 drives the cam 35 to rotate and continuously impact the adsorption plate 28, and then the dredging rod 29 continuously impacts the solid impurities stuck in the adsorption port 26, and finally cleans out the solid impurities stuck in the adsorption port 26 to prevent the adsorption port 26 from being blocked and affecting the next use.

[0041] In order to enable the dust removal water tank 11 to automatically discharge sewage, people can add clean water to the dust removal water tank 11 as soon as possible to prevent the dust from being incompletely adsorbed and drifting into the external environment again, causing air pollution. The automatic sewage discharge mechanism includes two longitudinal rods 43 fixedly installed in the dust removal water tank 11, and floating plates 44 are slidably installed on the two longitudinal rods 43. In order to limit the floating plates 44, the floating plates 44 are always slidably installed on the longitudinal rods 43 and do not contact the stirring plates 42 to prevent the rotation of the stirring plates 42 from being affected. The top ends of the two longitudinal rods 43 are respectively fixed with limit blocks for limiting the floating plates 44, and the bottom ends of the floating plates 44 are fixed with connecting rods 45. The bottom ends of the connecting rods 45 are fixed with conical rubber blocking blocks 46 for blocking the sewage pipe of the dust removal water tank 11. Two positive magnet blocks 48 are fixedly installed on the bottom of the floating plates 44, and the two longitudinal rods 43 are respectively fixed with limit blocks for limiting the floating plates 44. Two negative magnet rings 47 are provided, and the two negative magnet rings 47 do not contact the two positive magnet blocks 48. The negative magnet rings 47 attract the positive magnet blocks 48, so that the conical rubber block 46 is always attracted by the downward force and in close contact with the sewage pipe, thereby improving the sealing performance of the conical rubber block 46 and the sewage pipe. When the water in the dust removal water tank 11 absorbs dust, the density of the water in the dust removal water tank 11 also increases (according to the buoyancy formula, when the density of the liquid increases, the buoyancy of the object in the liquid also increases). Therefore, the buoyancy of the floating plate 44 gradually increases. When the water in the dust removal water tank 11 absorbs a large amount of dust and is about to reach saturation, the buoyancy of the floating plate 44 is greater than the magnetic force of the negative magnet rings 47 on the positive magnet blocks 48. Under the action of the buoyancy, the connecting rod 45 and the conical rubber block 46 are pulled upward to open the sewage pipe, thereby completing the automatic sewage discharge operation of the dust removal water tank 11.

[0042] In order to keep the water in the dust removal water tank 11 in a flowing state at all times, to have more comprehensive contact with the dust and to improve the dust adsorption rate, a mounting plate is fixedly installed in the L-shaped hard tube 10, on which a vertical rod 40 is rotatably installed, and a propeller 41 rotated by wind force is fixedly installed at the top of the vertical rod 40, and a number of stirring plates 42 that can stir the flow of adsorbed water in the dust removal water tank 11 are fixedly installed on the part of the vertical rod 40 located outside the L-shaped hard tube 10.

[0043] The working principle of the household photovoltaic energy storage device provided by the present invention is as follows; in the initial state, the torsion spring 39 is in a free state, the dust removal water tank 11 is filled with water for adsorbing dust, the bottom end of the L-shaped hard tube 10 is located below the water level, the negative magnet ring 47 is not in contact with the positive magnet block 48, and the positive magnet block 48 is subjected to a downward suction force through the magnetic force, so that the conical rubber block 46 is always subjected to a downward force and is in close contact with the sewage pipe in the dust removal water tank 11, thereby blocking the sewage pipe more tightly to prevent water leakage, and converting solar energy into direct current through the solar photovoltaic panel 5 to charge the battery 4 to complete the energy storage work. When dust adheres to the surface of the solar photovoltaic panel 5, the rotating motor 8 rotates to drive the reciprocating screw 6 to rotate, and the reciprocating screw The rotation of the rod 6 drives the movable plate 7 and the soft brush 13 to move to clean the dust adhering to the solar photovoltaic panel 5, thereby improving the light intensity of the solar photovoltaic panel 5 and thus improving the power generation efficiency. At the same time, the reciprocating screw 6 rotates to drive the long rod 12, the movable plate 7, and the movable gear 18 to rotate. The rotation of the movable gear 18 drives the slave gear 20, the cross bar 19, the first bevel gear 22, and the second bevel gear 23 to rotate, and finally drives the fan blades 21 to rotate to generate an upward wind force, so that a negative pressure is formed in the negative pressure cavity 14, (the adsorption ball 38 and the adsorption plate 28 move upward. Under the action of continuous negative pressure, the adsorption ball 38 is always subjected to an upward suction force, and finally the pull rope 37 also moves upward, and the friction force drives the winding rod 34 to rotate. The rotation of the winding rod 34 causes the torsion spring 39 to be rotated by the torsion spring 39. The free state becomes the stressed state), and at the same time, the adsorption plate 28 moves upward to drive the dredging rod 29 to move upward out of the adsorption port 26 to fully open the adsorption port 26, thereby allowing the cleaned dust to be adsorbed into the adsorption cavity 25, and finally transported to the dust removal water tank 11 through the connecting port 16, the annular cavity 24, the negative pressure cavity 14, the L-shaped connecting pipe 15, the corrugated connecting pipe 9, the L-shaped hard pipe 10 and the wind force generated by the rotation of the fan blades 21 to contact the water. At the same time, when the dust flows rapidly in the L-shaped hard pipe 10 with the wind force generated by the rotation of the fan blades 21, it drives the propeller 41 to rotate, and the rotation of the propeller 41 drives the stirring plate 42 to rotate, so that the water in the dust removal water tank 11 is always in a flowing state, which makes the contact with the dust more comprehensive, improves the adsorption rate of the dust, and completes the dust removal. During the dust collection operation, when the water in the dust removal water tank 11 absorbs the dust, the density of the water in the dust removal water tank 11 also increases. (From the buoyancy formula, it can be seen that when the density of the liquid increases, the buoyancy of the object in the liquid also increases accordingly). Therefore, the buoyancy of the floating plate 44 gradually increases. When the water in the dust removal water tank 11 absorbs a large amount of dust and is about to reach a saturated state, the buoyancy of the floating plate 44 is greater than the magnetic force of the negative magnet ring 47 on the positive magnet block 48. Under the action of the buoyancy, the connecting rod 45 and the conical rubber block 46 are pulled upward to open the drain pipe, thereby completing the automatic drainage operation of the dust removal water tank 11, so that people can add clean water to the dust removal water tank 11 as soon as possible to prevent the dust from being incompletely adsorbed and floating into the external environment again.The phenomenon of air pollution is caused. When some solid impurities are adsorbed into the adsorption port 26 and stuck after cleaning the solar photovoltaic panel 5, the rotating motor 8 is turned off. At this moment, the fan blades 21 no longer rotate to generate wind force, and there is no negative pressure in the negative pressure cavity 14. Under the action of gravity, the adsorption plate 28, the dredging rod 29, and the cam 35 fall directly downward, and the dredging rod 29 will fall directly into the adsorption port 26 and contact the solid impurities. At this moment, the adsorption ball 38 no longer maintains the upward movement trend due to being unaffected by the negative pressure, so that the winding rod 34 and the torsion spring 39 are no longer subjected to the upward pulling force of the adsorption ball 38. The torsion spring 39 returns to its original free state from the stressed state to drive the winding rod 34 to rotate. The rotation of the winding rod 34 drives the cam 35 to rotate and continuously hit the adsorption plate 28, and then the dredging rod 29 continuously hits the solid impurities stuck in the adsorption port 26, and finally cleans out the solid impurities stuck in the adsorption port 26, preventing the adsorption port 26 from being blocked and affecting the next use.

[0044] Compared with related technologies, the household photovoltaic energy storage device provided by the present invention has the following beneficial effects:

[0045] The present invention provides a household photovoltaic energy storage device, which converts sunlight energy into direct current through a solar photovoltaic panel 5 to charge a storage battery 4, thereby completing the energy storage work. The rotating motor 8 drives the movable plate 7 and the soft brush 13 to move to clean the dust adhering to the solar photovoltaic panel 5, thereby improving the light intensity received by the solar photovoltaic panel 5 and thus improving the power generation efficiency. At the same time, the reciprocating screw 6 rotates to drive the fan blades 21 to rotate to generate an upward wind force, so that a negative pressure is formed in the negative pressure cavity 14 (so that the torsion spring 39 changes from a free state to a stressed state), and at the same time, the dredging rod 29 moves upward out of the adsorption port 26 to complete the adsorption port 26. When the fan 21 is fully opened, the cleaned dust is adsorbed into the adsorption cavity 25, and finally transported to the dust removal water tank 11 through the connecting port 16, the annular cavity 24, the negative pressure cavity 14, the L-shaped connecting pipe 15, the corrugated connecting pipe 9, the L-shaped hard pipe 10 and the wind force generated by the rotation of the fan blades 21 to contact with water. At the same time, when the dust flows rapidly in the L-shaped hard pipe 10 with the wind force generated by the rotation of the fan blades 21, the propeller 41 and the stirring plate 42 are driven to rotate, so that the water in the dust removal water tank 11 is always in a flowing state, the dust contact is more comprehensive, the dust adsorption rate is improved, and the dust collection operation is completed. When the water in the dust removal water tank 11 absorbs a large amount of water, the dust is collected. When the dust is about to reach the saturation state, the buoyancy of the floating plate 44 is greater than the magnetic force of the negative magnet ring 47 on the positive magnet block 48, pulling the connecting rod 45 and the conical rubber block 46 upward to open the sewage pipe, thereby completing the automatic sewage discharge operation of the dust removal water tank 11, so that people can add clean water to the dust removal water tank 11 as soon as possible to prevent the dust from being incompletely adsorbed and drifting into the external environment again, causing air pollution. When the solar photovoltaic panel 5 is cleaned, some solid impurities are adsorbed into the adsorption port 26 and stuck, the rotating motor 8 is turned off, and there is no negative pressure in the negative pressure cavity 14. Under the action of gravity, the dredging rod 29 will fall directly to the adsorption port 26 and come into contact with the solid impurities. At this moment, the adsorption ball 38 no longer maintains the upward movement trend because it is not affected by the negative pressure, so that the winding rod 34 and the torsion spring 39 are no longer subjected to the upward pulling force of the adsorption ball 38. The torsion spring 39 will be restored from the stressed state to the original free state, driving the cam 35 to rotate and continuously impact the adsorption plate 28, and then the dredging rod 29 will continuously impact the solid impurities stuck in the adsorption port 26, and finally the solid impurities stuck in the adsorption port 26 will be cleared out to prevent the adsorption port 26 from being blocked and affecting the next use.

[0046] The present invention also provides a method for manufacturing a household photovoltaic energy storage device, comprising the following steps:

[0047] S1: The reciprocating screw 6 is driven to rotate by the rotating motor 8, and the reciprocating screw 6 drives the moving plate 7 and the soft brush 13 to move to clean the dust adhering to the solar photovoltaic panel 5;

[0048] S2: The reciprocating screw 6 rotates the fan blades 21 to form a negative pressure in the negative pressure cavity 14, so that the cleaned dust is adsorbed into the adsorption cavity 25 and finally transported to the dust removal water tank 11 through the connecting port 16, the annular cavity 24, the negative pressure cavity 14, the L-shaped connecting pipe 15, the corrugated connecting pipe 9, and the L-shaped hard pipe 10 to contact the water;

[0049] S3: The wind generated by the rotation of the fan blades 21 rapidly flows in the L-shaped hard tube 10, driving the propeller 41 and the stirring plate 42 to rotate, so that the water in the dust removal water tank 11 is always in a flowing state, and the dust is more fully contacted;

[0050] S4: When the water in the dust removal water tank 11 absorbs a large amount of dust and is about to reach saturation, the buoyancy of the floating plate 44 is greater than the magnetic force of the negative magnet ring 47 on the positive magnet block 48, pulling the connecting rod 45 and the conical rubber block 46 upward to open the sewage pipe and automatically discharge the sewage;

[0051] S5: By turning off the rotating motor 8, the torsion spring 39 is restored from the stressed state to the original free state, driving the cam 35 to rotate through the adsorption plate 28 and the dredging rod 29 to continuously impact the solid impurities stuck in the adsorption port 26, and finally clear out the solid impurities stuck in the adsorption port 26.
