Description

Technical Field

[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 to generate current; inverters convert direct current into alternating current for home or commercial use; photovoltaic power generation systems can be used on roofs, ground, photovoltaic power stations and other places, and are a clean and renewable energy generation method; photovoltaic power generation systems are usually installed in a simple grid-connected manner, 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 panel charges the battery, the photovoltaic panel is still absorbing light energy and converting it into electrical energy when the battery is fully charged.

The battery 42 is electrically connected to the two charging connectors 43 on the charging seat 41.

[0038] The present invention provides a method for using a photovoltaic device based on distributed energy storage, comprising the following steps: 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 height of the sun in different seasons. Rotate the threaded barrel 17, and the first screw 16 and the second screw 18 move away from or closer to each other, so that the distance between the positioning ring 15 and the hinge seat becomes larger or smaller, and then the support plate 14 rotates relative to the column 13, and the horizontal angle of the support plate 14 and the photovoltaic panel 19 is adjusted. When the first screw 16 and the second screw 18 move closer to 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.

[0039] 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, it is continued to be pushed 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 the battery 42 is installed, the light sensor 20 is started. Since the light sensor 20 and the photovoltaic panel 19 are both installed on the upper end surface of the support plate 14, the amount of light received by the light sensor 20 is consistent with the amount of light received by the photovoltaic panel 19. When the amount of light received by the light sensor 20 is less than the threshold, the drive motor 12 will be controlled to start. 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. The driven gear 8 drives the column 13 to rotate, and the column 13 drives the light sensor 20 and the photovoltaic panel 19 to rotate horizontally. When the light sensor 20 rotates until the light amount reaches a certain threshold, the drive motor 12 will be controlled to stop rotating, so that the photovoltaic mechanism stops rotating.

[0040] Step 3: When wind blows, the wind will blow to the two fans 27 on the back of the support plate 14 through the air guide 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.

[0041] Step 4: When the multiple batteries 42 in the storage box 36 are fully charged, the electric push rod 35 will be activated to control the two electric push rods 35 to shrink. When the piston rods of the two electric push rods 35 are gradually retracted, the two limit rods 34 are gradually drawn out from the two limit grooves of the limit plate 33, and the upper contact slope on the limit rod 34 is engaged with the lower contact slope of the limit groove. 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 are gradually raised, and the connecting gear 9 is out of mesh with the driving gear 10 and the driven gear 8. The driving motor 12 can no longer drive the photovoltaic panel 19 and the supporting plate 14 to rotate horizontally. When the supporting column 32 rises, it will drive the moving frame 37 to rise synchronously, and the moving frame 37 drives the charging seat 41 and the battery 42 inside it to rise synchronously. Since the lower acting slope on the charging seat 41 is in contact 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 of 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, 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 then the new battery 42 with insufficient power can be placed in the charging seat 41, and the charging seat 41 is pushed backward 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.
