They are generally connected to power grids with voltage levels below 35 kV or lower. Distributed photovoltaic power stations specifically refer to distributed photovoltaic power station systems that use photovoltaic modules to directly convert solar energy into electrical energy. Among them, household photovoltaics are a type of distributed photovoltaics. They have a small installation capacity and multiple installation points, and are usually installed on residents' own roofs.

[0003] The application document with announcement number CN116979878A records a distributed photovoltaic power station, including a direct illumination mechanism, which is used to adjust the positions of a plurality of solar photovoltaic panels fixedly mounted on the upper surface of a mounting plate and arranged on a gable roof, so that the plurality of solar photovoltaic panels can be aligned with the sun to ensure direct illumination, and the mounting plate is arranged on a bracket, the bottom end of the bracket is a gable structure. The distributed photovoltaic power station utilizes the natural phenomenon of the sun rising in the east and setting in the west, so that the installation and laying of solar photovoltaic panels can be fully applicable to the structure of a house with a gable roof, and there is no need to install solar photovoltaic panels on both sides of the gable roof, thereby avoiding the situation in which there is a backlit solar photovoltaic panel on the gable roof in the morning and afternoon every day and the solar photovoltaic panel cannot fully absorb solar energy, resulting in a low light energy conversion rate.

[0004] The above-mentioned distributed photovoltaic power station has certain shortcomings when in use. The above-mentioned distributed photovoltaic power station does not have a synchronous control structure. The distributed photovoltaic power station is usually installed on the roof. Affected by the size of the roof area, roofs of different specifications can be installed with different numbers of photovoltaic power stations. When the number of photovoltaic power stations is large, the control and installation difficulty of the photovoltaic power station is increased; secondly, the above-mentioned distributed photovoltaic power station does not have an auxiliary cleaning structure. When the number of distributed photovoltaic power stations is large, it is impossible to complete the cleaning operations of multiple groups of distributed photovoltaic power stations at one time, resulting in dust accumulation on the surface of the photovoltaic power station, reducing its power generation effect; at the same time, distributed photovoltaic power stations are mostly installed on roofs, and the conventional photovoltaic power station structure increases its installation difficulty. When the number of photovoltaic power stations is large, the use of traditional installation structures will increase the time required for the installation of the photovoltaic power station, and it does not have a quick installation structure.

[0025] During operation, firstly, a motor is used to drive a docking rotating rod to rotate. When one docking rotating rod rotates, the driving teeth and the first chain are used to drive the other docking rotating rod to rotate, so that the two docking rotating rods rotate synchronously. At this time, the steering leg is adjusted to a vertical state. At the same time, the docking sleeve is used to synchronously drive the support rod to rotate when the docking rotating rod rotates. Secondly, through the setting of the second chain, two groups of driving teeth are made to rotate synchronously. One group of driving teeth is used to control the rotation of the steering leg, and the other group of driving teeth is used to control the rotation of the side-rotating bottom plate. When the other group of driving teeth rotates, the driving teeth drive the steering teeth, so that the steering teeth drive the rotating rod, and the rotating rod drives the side-rotating bottom plate to rotate, thereby completing the synchronous angle adjustment of the solar panel, so that the steering leg can perform the angle adjustment operation. The tilt adjustment of the solar panel is completed synchronously at the same time. Secondly, after the solar panel is unfolded, because the first driver is composed of a motor and a gear structure, and the surface of the telescopic card rod is provided with a tooth groove structure used in conjunction with the first driver, when the first driver is running, the telescopic card rod can be extended by means of gears, so as to facilitate the support and fixation between the telescopic card rod and the limit card seat. The second driver is composed of a motor, a gear and a rotating rod structure. When the motor drives the rotating rod to rotate by means of the gear, the rotating rod drives the side-rotating support arm to rotate, thereby completing the side-rotation adjustment of the side-rotating support arm, so that after the side-rotating support arm of the supporting leg rotates a certain angle, the telescopic card rod is used to support and fix the docking rotating rod, thereby improving the structural stability of the solar panel, thereby completing the control and adjustment of several groups of solar panels at the same time.

[0026] 2. By setting up a cleaner, when the distributed photovoltaic power station is used, it can cooperate with its synchronous adjustment of several groups of solar panels to complete the cleaning operation of the surface of several groups of solar panels, thereby improving its use effect;

[0027] When in use, the solar panels are reset by rotating the side-rotating bottom plate and the supporting legs, so that several groups of solar panels are laid flat on the inner side of the splicing base; when several groups of side-rotating bottom plates are synchronously stored on the inner side of the splicing base, the sliding base can be used to drive the roller brush to move, and the slide groove structure at the upper end of the first substrate can be used to make the roller brush contact with several groups of solar panels when moving. The roller brush is driven to rotate by a motor, and dust accumulation on several groups of solar panels can be cleaned when the roller brush moves. The upper spray frame can be used to rinse the surface of the solar panels, and when the roller brush moves to the inside of the cleaner, the lower spray frame can be used in conjunction with the liquid collecting tank to perform a flushing operation when the roller brush rotates, and the sewage generated by the roller brush can be collected through the liquid collecting tank and discharged outward.

[0028] 3. By setting a side-rotating clamp, the distributed photovoltaic power station has a foldable storage structure when in use, making the roof installation operation of the distributed photovoltaic power station more labor-saving;

[0029] During operation, the first substrate and the second substrate are first assembled using the card strip structure, so that the first substrate and the second substrate constitute a combined board, and then the strip card blocks of the side-rotating card are used to connect the card slot structures of the two groups of first substrates, so that the side-rotating card is assembled between the two combined boards, and the connection and fixation of several combined boards are completed by the side-rotating card. The two groups of combined boards are folded against each other by the hinge of the side-rotating card, so that several groups of combined boards are stacked in a Z shape, so that the photovoltaic power station is stacked and stored, making its installation operation more labor-saving, and the transfer operation of multiple photovoltaic power stations can be completed at one time.

DETAILED DESCRIPTION

[0038] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0039] like Figure 1 As shown, a distributed photovoltaic power station and a method of using the same include a splicing base 1 and several groups of side-rotating bottom plates 5, wherein the several groups of side-rotating bottom plates 5 are movably mounted on the upper part of the splicing base 1, and the upper outer surfaces of the several groups of side-rotating bottom plates 5 are fixedly mounted with solar panels 6. The splicing base 1 includes several groups of combined panels 2, which are movably connected to each other through side-rotating clamps 29. The combined panels 2 are composed of a first substrate 22 and a second substrate 23, and the first substrate 22 is spliced ​​and mounted on the outer surfaces of both ends of the second substrate 23. The side-rotating bottom plate 5 and the first substrate 22 are movably connected through steering legs 4, and the side-rotating bottom plate 5 and the second substrate 23 are movably connected through supporting legs 3. A docking rotating rod 31 is installed between the supporting legs 3 and the steering legs 4. The two groups of steering legs 4 are connected by a first chain 9 and a driving tooth 8, and the steering leg 4 and the side-rotating bottom plate 5 are connected by a driving tooth 8 and a steering tooth 10. A second chain 12 is arranged between the steering leg 4 and the docking rotating rod 31.

[0040] To solve the synchronous control problem of distributed photovoltaic power stations, such as Figure 2 As shown, the side rotating bottom plate 5 and the upper end of the steering leg 4 are movably connected by a rotating rod, the steering gear 10 is fixedly installed on the outer surface of one end of the rotating rod, the first base plate 22 and the second base plate 23 are spliced ​​and fixed by a clamping strip, the first base plate 22 is an L-shaped structure as a whole, and the first chain 9 and the second chain 12 are used to cooperate with the gear structure to form a synchronous adjustment structure between several groups of solar panels 6. During operation, a motor is first used to drive a docking rotating rod 31 to rotate, and when one docking rotating rod 31 rotates, the driving gear 8 and the first chain 9 are used to drive the other docking rotating rod 31 to rotate, so that The two docking rotating rods 31 rotate synchronously. At this time, the steering leg 4 is adjusted to a vertical state. At the same time, when the docking rotating rod 31 rotates, the docking sleeve 13 is used to synchronously drive the support rod 19 to rotate. Secondly, through the setting of the second chain 12, the two groups of driving teeth 8 rotate synchronously, one group of driving teeth 8 is used to control the rotation of the steering leg 4, and the other group of driving teeth 8 is used to control the rotation of the side rotating bottom plate 5. When the other group of driving teeth 8 rotates, the driving teeth 8 drive the steering teeth 10, so that the steering teeth 10 drive the rotating rod, and the rotating rod drives the side rotating bottom plate 5 to rotate, thereby completing the synchronous angle adjustment of the solar panel 6.

[0041] like Figure 3As shown, the support leg 3 includes a fixed base 14 and a support rod 19, the support rod 19 is movably mounted on the upper end of the fixed base 14, and the fixed base 14 and the support rod 19 are movably connected via a rotating shaft 15, and a side-rotating support arm 18 is movably mounted on one side of the support rod 19. When several groups of side-rotating bottom plates 5 and solar panels 6 complete the unfolding operation, the support leg 3 can be used to provide auxiliary support through the side-rotating support arm 18 to improve the stability of the solar panel 6 after unfolding.

[0042] like Figure 3 As shown, a second driver 20 is arranged between the support rod 19 and the side-rotating support arm 18, and a telescopic clamping rod 16 is movably installed on the inner side of one end of the side-rotating support arm 18. A first driver 17 is arranged between the side-rotating support arm 18 and the telescopic clamping rod 16. The first driver 17 is assembled by a motor and a gear structure, and the surface of the telescopic clamping rod 16 is provided with a tooth groove structure used in conjunction with the first driver 17. When the first driver 17 is running, the telescopic clamping rod 16 can be extended by means of gears, so as to facilitate the support and fixation between the telescopic clamping rod 16 and the limit clamping seat 30. The second driver 20 is composed of a motor, a gear and a rotating rod structure. When the motor drives the rotating rod to rotate by means of gears, the rotating rod drives the side-rotating support arm 18 to rotate, thereby completing the side-rotation adjustment of the side-rotating support arm 18.

[0043] A docking sleeve 13 is provided at one end of the rotating shaft 15, and the rotating shaft 15 and the docking rotating rod 31 are connected through the docking sleeve 13. The bottoms of the first substrate 22 and the second substrate 23 are both provided with insulation pads 21, and the bottoms of the insulation pads 21 are provided with a plurality of groups of strip grooves. The insulation pads 21 are used in conjunction with the strip grooves to improve the thermal insulation performance of the splicing base 1 and avoid overheating on the roof of the house.

[0044] To solve the cleaning problem of distributed photovoltaic power stations, such as Figure 4 As shown, a cleaner 7 is fixedly mounted on the outer surface of one end of the splicing base 1, and a roller brush cylinder 25 is movably mounted inside the cleaner 7, both ends of the roller brush cylinder 25 are provided with sliding bases 24, and the upper part of the first substrate 22 is provided with a slide groove used in conjunction with the sliding base 24. When several groups of side-rotating bottom plates 5 are synchronously stored on the inner side of the splicing base 1, the sliding base 24 can be used to drive the roller brush cylinder 25 to be used, and the roller brush cylinder 25 is driven to rotate by a motor, and when the roller brush cylinder 25 moves, the dust accumulation of several groups of solar panels 6 can be cleaned.

[0045] A liquid collecting tank 26 is provided at the lower inner part of the cleaner 7, a lower spray frame 28 is provided at the inner side of the cleaner 7 above the liquid collecting tank 26, an upper spray frame 27 is provided at the upper end of the cleaner 7, and both the upper spray frame 27 and the lower spray frame 28 are equipped with a plurality of groups of nozzles. The upper spray frame 27 can be used to flush the surface of the solar panel 6, and the lower spray frame 28 can be used in conjunction with the liquid collecting tank 26 to perform flushing operations when the roller brush drum 25 rotates.

[0046] like Figure 5 As shown, the upper surfaces of the first substrate 22 and the second substrate 23 are both provided with a limit clamping seat 30 , and the ends of the first substrate 22 and the second substrate 23 are both provided with a clamping groove used to cooperate with the side-rotating clamp 29 .

[0047] like Figure 6 As shown, the side-rotating clamp 29 includes a hinge 32 and a strip clamp block 11. The strip clamp block 11 is fixedly installed on one side outer surface of the hinge 32. The other side outer surface of the hinge 32 is provided with an arc-shaped clamp head 33 and a clamping groove. The side-rotating clamp 29 can be used to stack several groups of combined panels 2 in a Z shape, making the storage operation of the splicing base 1 more labor-saving.

[0048] A method for using a distributed photovoltaic power station comprises the following steps:

[0049] Step 1: Use the side-rotating clamp 29 to unfold the combined panel 2 so that the combined panel 2 is laid flat on the roof. After the combined panel 2 is unfolded, a splicing base 1 is formed. The motor drives the docking rod 31, and the first chain 9 and the second chain 12 are used to complete the unfolding operation of the solar panel 6.

[0050] Step 2, when the solar panels 6 are stored inside the splicing base 1, several groups of solar panels 6 are in a flat state, and the sliding base 24 is used to drive the roller brush 25 to rotate through the motor, and the roller brush 25 moves to complete the dust cleaning of several groups of solar panels 6.

[0051] When in use, traditional distributed photovoltaic power stations do not have a synchronous control structure. Distributed photovoltaic power stations are usually installed on roofs. Affected by the size of the roof area, different numbers of photovoltaic power stations can be installed on roofs of different specifications. When the number of photovoltaic power stations is large, the control difficulty of the photovoltaic power station is increased, and the regulation and control operations of multiple groups of photovoltaic power stations cannot be completed synchronously;

[0052] By providing the support legs 3 and the steering legs 4, when the distributed photovoltaic power station is used, in conjunction with the use of the toothed chain structure, it can simultaneously complete the control and adjustment of several groups of solar panels 6, thereby improving its flexibility in use;

[0053] During operation, firstly, a motor is used to drive a docking rotating rod 31 to rotate. When one docking rotating rod 31 rotates, the driving teeth 8 and the first chain 9 are used to drive the other docking rotating rod 31 to rotate, so that the two docking rotating rods 31 rotate synchronously. At this time, the steering leg 4 is adjusted to a vertical state. At the same time, the docking sleeve 13 is used to synchronously drive the support rod 19 to rotate when the docking rotating rod 31 rotates. Secondly, through the setting of the second chain 12, two groups of driving teeth 8 are made to rotate synchronously. One group of driving teeth 8 is used to control the rotation of the steering leg 4, and the other group of driving teeth 8 is used to control the rotation of the side rotating bottom plate 5. When the other group of driving teeth 8 rotates, the driving teeth 8 drive the steering teeth 10, so that the steering teeth 10 drive the rotating rod, and the rotating rod drives the side rotating bottom plate 5 to rotate, thereby completing the synchronous angle adjustment of the solar panel 6, so that the steering leg 4 can adjust the angle. During operation, the tilt adjustment of the solar panel 6 is completed synchronously. Secondly, after the solar panel 6 is unfolded, because the first driver 17 is composed of a motor and a gear structure, and the surface of the telescopic card rod 16 is provided with a toothed structure used in conjunction with the first driver 17, when the first driver 17 is running, the telescopic card rod 16 can be extended by means of gears, so as to facilitate the support and fixation between the telescopic card rod 16 and the limit card seat 30. The second driver 20 is composed of a motor, a gear and a rotating rod structure. When the motor drives the rotating rod to rotate by means of the gear, the rotating rod drives the side rotation support arm 18 to rotate, thereby completing the side rotation adjustment of the side rotation support arm 18, so that after the side rotation support arm 18 of the supporting leg 3 rotates a certain angle, the telescopic card rod 16 is used to support and fix the docking rotating rod 31, thereby improving the structural stability of the solar panel 6, thereby completing the control adjustment of several groups of solar panels 6 at the same time;

[0054] Secondly, the distributed photovoltaic power station does not have an auxiliary cleaning structure. When a large number of distributed photovoltaic power stations are installed, it is impossible to complete the cleaning operations of multiple distributed photovoltaic power stations at one time, resulting in dust accumulation on the surface of the photovoltaic power station, reducing its power generation effect;

[0055] To this end, by setting up a cleaner 7, when the distributed photovoltaic power station is used, it can cooperate with the synchronous adjustment of the plurality of groups of solar panels 6 to complete the cleaning operation of the surface of the plurality of groups of solar panels 6, thereby improving the use effect thereof;

[0056] When in use, the solar panel 6 is reset by rotating the side rotating bottom plate 5 and the supporting leg 3, so that several groups of solar panels 6 are laid flat on the inner side of the splicing base 1. When several groups of side rotating bottom plates 5 are synchronously stored on the inner side of the splicing base 1, the sliding base 24 can be used to drive the roller brush drum 25 to move, and the sliding groove structure at the upper end of the first substrate 22 can be used to make the roller brush drum 25 contact with several groups of solar panels 6 when moving. The roller brush drum 25 is driven by the motor to rotate, and the dust accumulation of several groups of solar panels 6 can be cleaned when the roller brush drum 25 moves. The upper spray frame 27 can be used to rinse the surface of the solar panel 6. When the roller brush drum 25 moves to the inside of the cleaner 7, the lower spray frame 28 can be used to cooperate with the liquid collecting tank 26 to perform the rinsing operation when the roller brush drum 25 rotates. The sewage generated by the roller brush drum 25 can be collected by the liquid collecting tank 26 and discharged outward.

[0057] At the same time, distributed photovoltaic power stations are mostly installed on roofs. The conventional photovoltaic power station structure increases the difficulty of installation. When there are a large number of photovoltaic power stations, the traditional installation structure will increase the time required for the installation of the photovoltaic power station, and it does not have a quick installation structure.

[0058] To this end, by providing the side-rotating clamp 29, when the distributed photovoltaic power station is used, it has a foldable storage structure, making the roof installation operation of the distributed photovoltaic power station more labor-saving;
