Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic appliances, and in particular relates to a photovoltaic device based on distributed energy storage. Background Art

[0002] Photovoltaic power generation is the process of converting sunlight into electrical energy using the photovoltaic effect. A photovoltaic power generation system consists of photovoltaic modules, inverters, brackets, and other auxiliary equipment. Photovoltaic modules are usually composed of solar panels. When sunlight shines on the panels, photons excite electrons, generating current. Inverters convert direct current into alternating current for home or commercial use. Photovoltaic power generation systems can be used on roofs, on the ground, in photovoltaic power stations, and are a clean, renewable energy generation method. Photovoltaic power generation systems are usually installed using a simple grid-connected method, that is, directly connecting the photovoltaic power generation system to the power grid. Although this method is easy to operate, there are also some problems, such as possible impact on the power grid, photovoltaic power fluctuations, etc., and when the photovoltaic panels charge the batteries, even when the batteries are fully charged, the photovoltaic panels are still absorbing light energy and converting it into electrical energy. At this time, the electrical energy converted by the photovoltaic panels cannot be stored, which will cause excessive use of the photovoltaic panels, thereby reducing the service life of the photovoltaic panels. Therefore, improvements need to be made based on the above problems. Summary of the Invention

[0033] like Figure 1 —As shown in FIG12 , the present invention provides a photovoltaic device based on distributed energy storage, comprising a base 1, a drive box 2 being provided at the upper end of the base 1, a drive mechanism being provided inside the drive box 2, the drive mechanism comprising a drive gear 10, a connecting gear 9, and a driven gear 8 that are meshed in sequence; a charging mechanism and a photovoltaic mechanism are provided on the drive box 2, the connecting gear 9 is connected to the charging mechanism, and the driven gear 8 is connected to the photovoltaic mechanism; the photovoltaic mechanism comprises a vertical rotatable column 13, a support plate 14 is rotatably provided at the upper end of the column 13, a photovoltaic panel 19 and a cleaning component are provided on the support plate 14, the cleaning component comprises a cleaning rod 23, and the cleaning rod 23 is swingably provided at the upper end of the photovoltaic panel 19.

[0034] The base 1 is a horizontally mounted square plate-like structure. The drive box 2 is a square box structure with an open lower end. A box 3 is fixedly mounted on the upper end surface of the drive box 2, and an openable door 4 is provided on the front side wall of the box 3. The charging mechanism is located inside the box 3, and the photovoltaic mechanism is located on one side of the box 3.

[0035] The drive mechanism also includes a drive motor 12 and a reducer 11. The drive motor 12 and the reducer 11 are both fixedly disposed within the housing 3. The output shaft of the drive motor 12 is fixedly connected to the input shaft of the reducer 11. The output shaft of the reducer 11 extends vertically downward into the drive housing 2, and the output shaft of the reducer 11 is fixedly connected to the drive gear 10. The lower end of the column 13 extends into the drive housing 2, and the lower end of the column 13 is rotationally connected to the upper end surface of the base 1. The driven gear 8 is fixedly sleeved on the outer side of the column 13, and the column 13 rotates synchronously with the driven gear 8. The drive motor 12 drives the drive gear 10 to rotate horizontally through the reducer 11. The drive gear 10 drives the driven gear 8 to rotate through the connecting gear 9, and the driven gear 8 drives the column 13 to rotate.

[0036] The photovoltaic mechanism further includes a positioning ring 15 , a first screw 16 , a second screw 18 , a threaded barrel 17 , and a light sensor 20 .

[0037] The support plate 14 is a flat, inclined structure. The center of the lower end of the support plate 14 is hinged to the upper end of the column 13. The photovoltaic panel 19 is fixedly mounted on the upper end of the support plate 14. A baffle is fixedly mounted at one edge of the downwardly slanted end of the support plate 14. The baffle is perpendicular to the support plate 14 and serves to limit the position of the photovoltaic panel 19, ensuring that the panel 19 can be installed or replaced more conveniently and quickly.

[0038] A positioning ring 15 is fixedly sleeved on the outer middle portion of the column 13, and a hinge seat is fixedly installed in the middle of the tilted upward end of the lower end surface of the support plate 14. A first screw 16 is rotatably mounted on the positioning ring 15, and a second screw 18 is rotatably mounted on the hinge seat. The external threads of the first screw 16 and the second screw 18 are rotated in opposite directions. The threaded barrel 17 is a cylindrical structure with two open ends. The two openings of the threaded barrel 17 are internally provided with external threads with opposite rotations. The end of the first screw 16 away from the positioning ring 15 and the end of the second screw 18 away from the hinge seat are respectively screwed into the two openings of the threaded barrel 17. When the threaded barrel 17 is rotated, the first screw 16 and the second screw 18 move away from or toward each other, thereby increasing or decreasing the distance between the positioning ring 15 and the hinge seat, thereby causing the support plate 14 to rotate relative to the column 13, and adjusting the angles of the support plate 14 and the photovoltaic panel 19.

[0039] A light sensor 20 is fixedly provided at the middle of the upper end of the supporting plate 14 which is inclined upward. The model of the light sensor 20 is NHZD10AU2.

[0040] The cleaning assembly further includes a turntable 21 , a connecting rod 22 , a fixing rod 24 , a fixing seat 25 , a connecting plate 26 , a fan 27 , and a transmission shaft 28 .

[0041] Two turntables 21 are rotatably mounted on the upper, upwardly tilted end of the support plate 14. The two turntables 21 are symmetrically positioned on either side of the light sensor 20, maintaining parallelism with the support plate 14. The turntable 21 is a circular plate-like structure, with a drive shaft 28 fixedly mounted at the center of the lower end of the turntable 21. The drive shaft 28 is perpendicular to the turntable 21. The end of the drive shaft 28 away from the turntable 21 passes through the support plate 14 and is fixedly mounted with a fan 27. The fan 27 drives the turntable 21 to rotate synchronously via the drive shaft 28. Two fixed bases 25 are fixedly mounted on the upper, downwardly tilted end of the support plate 14, each of which has an L-shaped connecting plate 26 fixed thereto. The two drive shafts 28 are rotatably plugged into the ends of the two connecting plates 26 away from the fixed bases 25.

[0042] Two fixed rods 24 are also fixedly mounted on the upper end surface of the support plate 14. The two fixed rods 24 are located on the downward-sloping sides of the two turntables 21; the fixed rods 24 remain perpendicular to the support plate 14. Two cleaning rods 23 are rotatably sleeved onto the outer sides of the two fixed rods 24. The downward-sloping ends of the cleaning rods 23 are equipped with cleaning bristles, which maintain contact with the upper end surfaces of the photovoltaic panels 19. The upward-sloping ends of the cleaning rods 23 are provided with waist-shaped grooves, the length of which is consistent with the length of the cleaning rods 23. A connecting rod 22 is fixedly mounted on the outer edge of the upper end surfaces of the two turntables 21. The connecting rods 22 remain perpendicular to the turntables 21 and are inserted into the waist-shaped grooves of the two cleaning rods 23.

[0043] A U-shaped mounting plate 5 is fixedly mounted on the upper edge of the housing 3, near the photovoltaic mechanism. The U-shaped opening of the mounting plate 5 points vertically upward. An air duct 6 is fixedly mounted within the mounting plate 5. A protective net 7 is fixed to the opening of the duct 6 facing away from the photovoltaic mechanism. The opening of the duct 6 facing the photovoltaic mechanism covers the outside of the two fans 27. The end of the duct 6 facing away from the photovoltaic mechanism is a rigid tube, and its angle cannot be adjusted. The end of the duct 6 facing the photovoltaic mechanism is a flexible tube, which can be adjusted according to the position of the fans 27.

[0044] Airflow enters through one end of the rigid tube of the air duct 6 and blows toward the two fans 27 from the flexible tube end of the air duct 6, thereby driving the two fans 27 to rotate. The two fans 27 drive the two turntables 21 to rotate via the transmission shaft 28. The two turntables 21 drive the two connecting rods 22 to rotate. The connecting rods 22 slide back and forth within the waist-shaped grooves of the cleaning rods 23, thereby driving the two cleaning rods 23 to swing back and forth around the fixed rods 24. During the reciprocating swing, the cleaning rods 23 clean the surface of the photovoltaic panel 19.

[0045] The charging mechanism includes a rotating block 29, a positioning plate 30, a spring 31, a supporting column 32, a limiting plate 33, a limiting rod 34, an electric push rod 35, a storage box 36, a moving frame 37, a partition 38, a wedge block 39, a charging block 40, a charging seat 41, and a battery 42.

[0046] A mounting slot is provided in the middle of the upper end surface of the base 1, communicating with the interior of the drive box 2. A horizontal positioning plate 30 is positioned at the upper opening of the mounting slot. A cylindrical rotating block 29 is fixedly mounted at the center of the upper end surface of the positioning plate 30.

Multiple vertical springs 31 are fixedly mounted on the bottom surface of the mounting slot, with the upper ends of the springs 31 fixedly connected to the lower end surface of the positioning plate 30.

[0047] A vertical support column 32 is fixedly mounted on the upper end of the rotating block 29. The upper end of the support column 32 extends through the top plate of the drive box 2 and into the interior of the box 3. A U-shaped stopper plate 33 is fixedly mounted in the middle of the outer side of the support column 32. This stopper plate 33 is located inside the drive box 2, with the U-shaped opening of the stopper plate 33 pointing vertically downward. The stopper plate 33 comprises a horizontal section and two vertical sections. The upper ends of the two vertical sections are fixedly connected to the ends of the horizontal section, and the middle portions of the horizontal sections are fixedly connected to the support column 32.

Two electric push rods 35 are also provided inside the drive box 2. A horizontal limit rod 34 is fixedly provided at one end of the piston rod of the two electric push rods 35. The two limit rods 34 are respectively inserted into the two limit grooves; an upper contact inclined surface is provided at the end of the lower end surface of the limit rod 34 away from the electric push rod 35.

[0048] When the piston rods of the two electric push rods 35 extend outward, the two limit rods 34 are fully inserted into the two limit slots of the limit plate 33, and the upper contact bevel on the limit rod 34 completely passes the lower contact bevel of the limit slot. At this time, the limit rod 34, the supporting column 32, the rotating block 29, the positioning plate 30, and the connecting gear 9 are all at the lowest height, the spring 31 is compressed, and the connecting gear 9 remains engaged with the driving gear 10 and the driven gear 8. When the piston rods of the two electric push rods 35 are gradually retracted, the two limit rods 34 are gradually withdrawn from the two limit slots of the limit plate 33, and the upper contact bevel on the limit rod 34 engages with the lower contact bevel of the limit slot. Under the action of the rebound force of the spring 31, the positioning plate 30, the rotating block 29, the connecting gear 9, the limit plate 33, and the supporting column 32 gradually rise, and the connecting gear 9 is disengaged from the driving gear 10 and the driven gear 8.

[0049] A storage box 36 is fixedly mounted within the housing 3. This box is a square structure with an open front end. Inside this box is a movable frame 37, a square structure with open front and back ends. Two horizontal partitions 38 are fixedly mounted within this movable frame 37, dividing the interior of the movable frame 37 into three independent storage spaces: upper, middle, and lower. The upper ends of the support columns 32 extend through the bottom of the storage box 36 and are fixedly connected to the lower end of the movable frame 37. The movable frame 37 rises and falls synchronously with the support columns 32.

[0050] Three cubic wedges 39 are fixedly mounted on the rear inner wall of the storage box 36: upper, middle, and lower. These wedges 39 are located on the upper rear sides of the three storage spaces of the movable frame 37, respectively. Upper active slopes are provided on the front edges of the lower faces of the wedges 39. Below each wedge 39 is a charging block 40, fixed to the rear inner wall of the storage box 36 and electrically connected to the photovoltaic panels 19.

[0051] A charging seat 41 is provided inside each storage space of the movable frame 37 so as to slide along the front-to-back direction. The charging seat 41 is an L-shaped block structure. The charging seat 41 includes a horizontal block and a vertical block. The lower end of the vertical block is fixedly connected to the rear end of the horizontal block. A charging slot is provided at the rear end of the vertical block. The three charging blocks 40 are respectively located inside the charging slots of the three charging seats 41. The charging blocks 40 are electrically connected to the charging seats 41. A lower side action slope is provided at the upper edge of the rear end face of the vertical block of each charging seat 41; the lower side action slopes of the three charging seats 41 are respectively fitted with the upper side action slopes of the three wedge blocks 39. Two charging connectors 43 are provided on the front end face of the vertical block of each charging seat 41. A detachable battery 42 is provided inside each charging seat 41. The battery 42 is electrically connected to the two charging connectors 43 on the charging seat 41.

[0052] The present invention provides a method for using a photovoltaic device based on distributed energy storage, comprising the following steps:

[0053] Step 1: First, connect the drive motor 12 and the electric push rod 35 with wires and power them on. Then, adjust the horizontal angle of the support plate 14 according to the solar altitude in different seasons. Rotate the threaded barrel 17, and the first screw 16 and the second screw 18 move away from or toward each other, thereby increasing or decreasing the distance between the positioning ring 15 and the hinge seat, thereby rotating the support plate 14 relative to the column 13, and adjusting the horizontal angle of the support plate 14 and the photovoltaic panel 19. When the first screw 16 and the second screw 18 move toward each other, the support plate 14 and the photovoltaic panel 19 gradually become parallel to the ground; when the first screw 16 and the second screw 18 move away from each other, the angle between the support plate 14 and the photovoltaic panel 19 and the ground gradually increases.

[0054] Step 2. After the horizontal angle of the support plate 14 is determined, one end of the hose of the air duct 6 is put on the back of the support plate 14 to cover the two fans 27 on the back; then the box door 4 is opened, and multiple batteries 42 are pushed into the charging seat 41 in turn. After the battery 42 is connected to the charging seat 41 through the charging connector 43, continue to push it to the rear end so that the charging slot at the rear end of the charging seat 41 is connected to the charging block 40, so that it can charge the electrical energy converted from light energy into the battery 42. After battery 42 is installed, light sensor 20 is activated. Since both light sensor 20 and photovoltaic panel 19 are mounted on the upper surface of support plate 14, the amount of light received by light sensor 20 is consistent with the amount of light received by photovoltaic panel 19. When the amount of light received by light sensor 20 falls below a threshold, drive motor 12 is activated. Drive motor 12 drives drive gear 10 horizontally through reducer 11. Drive gear 10 drives driven gear 8 horizontally through connecting gear 9. Drive gear 8 drives column 13 to rotate, which in turn drives light sensor 20 and photovoltaic panel 19 horizontally. When light sensor 20 detects that the amount of light has reached a certain threshold, it controls drive motor 12 to stop, thereby stopping the photovoltaic mechanism.

[0055] Step 3: When wind blows, the wind will be blown to the two fans 27 on the back of the support plate 14 through the air duct 6, thereby driving the two fans 27 to rotate. The two fans 27 drive the two turntables 21 to rotate through the transmission shaft 28, and the two turntables 21 drive the two connecting rods 22 to rotate. The connecting rods 22 slide back and forth inside the waist-shaped grooves of the cleaning rods 23, thereby driving the two cleaning rods 23 to swing back and forth around the fixed rods 24. During the reciprocating swing, the cleaning rods 23 clean the surface of the photovoltaic panel 19.

[0056] Step 4: When the multiple batteries 42 in the storage box 36 are fully charged, the electric push rods 35 are activated, controlling the two electric push rods 35 to retract. As the piston rods of the two electric push rods 35 gradually retract, the two limit rods 34 are gradually withdrawn from the two limit slots of the limit plate 33. The upper contact slopes on the limit rods 34 engage with the lower contact slopes of the limit slots. Under the rebound force of the spring 31, the positioning plate 30, the rotating block 29, the connecting gear 9, the limit plate 33, and the supporting column 32 all gradually rise. The connecting gear 9 disengages from the drive gear 10 and the driven gear 8. The drive motor 12 can no longer drive the photovoltaic panel 19 and the supporting plate 14 to rotate horizontally. As the supporting column 32 rises, it drives the movable frame 37 to rise synchronously, and the movable frame 37 drives the charging base 41 and the batteries 42 inside it to rise synchronously. Since the lower acting slope on the charging seat 41 fits with the upper acting slope on the wedge block 39, as the charging seat 41 gradually rises, under the interaction of the lower acting slope and the upper acting slope, the charging seat 41 drives the battery 42 to slide toward the outside of the front end opening of the movable frame 37, thereby causing the charging seat 41 to disengage from the charging block 40, thereby stopping charging the battery 42, and both the battery 42 and the charging seat 41 slide to the outside of the movable frame 37. Then, the piston rods of the two electric push rods 35 are controlled to extend, and the two limit rods 34 are gradually inserted into the two limit grooves of the limit plate 33. Under the action of the upper contact slope and the lower contact slope, the positioning plate 30, the rotating block 29, the connecting gear 9, the limit plate 33, and the supporting column 32 gradually descend again, the spring 31 is compressed again, and the connecting gear 9 is meshed with the driving gear 10 and the driven gear 8 again. The driving motor 12 can drive the photovoltaic panel 19 and the supporting plate 14 to rotate horizontally, and the supporting column 32 drives the moving frame 37 to descend to the initial height again. At this time, the fully charged battery 42 can be taken out, and the new battery 42 with insufficient power can be placed in the charging seat 41. The charging seat 41 is pushed back to the inner rear side of the moving frame 37 so that the charging seat 41 is connected to the charging block 40, so that the new battery 42 can be charged.
