Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panels, and in particular to an integrated photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation systems are mainly composed of three parts: solar panels (modules), controllers and inverters. Integrated photovoltaic power generation devices often integrate the three parts to convert solar energy into electrical energy for storage.

[0003] For example, the patent with announcement number CN205545080U discloses an integrated photovoltaic power generation device, including: a photovoltaic power generation panel, a metal frame of the photovoltaic power generation panel, a connecting plate and a keel for fixing to the building structure, an installation groove extends from the inner side of the side wall of the metal frame, a reinforcing wall is provided below the installation groove, the photovoltaic power generation panel is fixed in the installation groove, the outer side of the side wall of the metal frame is fixed to the keel through a connecting device, a connecting plate is provided above the metal frames of two adjacent photovoltaic power generation panels, and sealant is filled between the connecting plate and the metal frame. The lower side of the integrated photovoltaic power generation device is fixed to the steel keel through connecting structures such as angle brackets, and the upper side connects adjacent photovoltaic power generation panels together through a connecting plate. The structural design is reasonable and easy to install and maintain.

[0004] However, the above photovoltaic power generation integrated device cannot make the photovoltaic panel rotate along with the sun's revolution during use, and cannot automatically sweep away the dust on the surface of the photovoltaic panel after long-term use. Since photovoltaic panels cannot rotate with the sun's revolution, they cannot always maintain the best angle with the sun's rays. During the day, the sun's position changes constantly. When the photovoltaic panels are fixed, the angle between the sun's rays and the photovoltaic panels may be small during certain periods. According to the principle of the photovoltaic effect, the power generation efficiency is highest when the light is incident vertically on the photovoltaic panels. However, when the fixed photovoltaic panels are not incident vertically, the effective light intensity received will be reduced, making it impossible for the photovoltaic panels to fully utilize the low-angle sunlight. At the same time, dust on the surface of photovoltaic panels will block the intensity of sunlight reaching the photovoltaic panels, reducing the number of photons that can be absorbed by photovoltaic materials, thereby reducing the photoelectric conversion efficiency of photovoltaic panels and ultimately reducing power generation. Summary of the invention

[0026] 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.

[0027] See also Figure 1-Figure 9 , this embodiment provides the following technical solutions: like Figure 1-Figure 2 As shown, a photovoltaic power generation integrated device comprises: a support seat 1, a connecting column 109 is rotatably mounted on the upper surface of the support seat 1, a triangular box 102 is fixedly mounted on the upper end of the connecting column 109, a following mechanism 2 is rotatably mounted in the triangular box 102, a first connecting frame 103 is rotatably mounted on one end of the triangular box 102, and second connecting frames 104 are rotatably mounted on the four corners of the first connecting frame 103, so that four groups of second connecting frames 104 can be turned over and folded to form a square frame; The first connecting frame 103 and the second connecting frame 104 are both paved with photovoltaic panels, and the other end of the following mechanism 2 is rotatably installed on one end of the first connecting frame 103, so that the following mechanism 2 can push the first connecting frame 103 and the second connecting frame 104 to rotate along the trajectory of the sun. As the sun rises and sets, the photovoltaic panels can smoothly follow the trajectory of the sun, thereby improving power generation efficiency. The first connecting frame 103 has four corners fixedly mounted with first connecting plates 106, and each group of second connecting frames 104 rotatably connected to the first connecting frame 103 has a second connecting plate 105 fixedly mounted on its end. The upper surface of the first connecting plate 106 has a locking mechanism 4 fixedly mounted, and the locked sleeve end of the locking mechanism 4 is fixedly mounted on the upper surface of the second connecting plate 105, so that the second connecting frame 104 can be locked by the locking mechanism 4 fixedly mounted on the upper surface of the first connecting frame 103 through the locked sleeve end of the locking mechanism 4, so that the second connecting frame 104 can be locked and pulled to be flush with the first connecting frame 103; Among them, a fastening plate 111 is fixedly installed at the central part of the first connecting frame 103, and a brushing mechanism 3 is fixedly installed at one end of the fastening plate 111. The brushing ends of the brushing mechanism 3 are rotatably installed at one end of the first connecting frame 103 and the second connecting frame 104 respectively, and the brushing ends of the brushing mechanism 3 penetrate to the surface of the photovoltaic panel and contact with the surface of the photovoltaic panel to perform a brushing operation.

[0028] After the locking mechanism 4 locks the unfolded second connecting frame 104 , the first connecting frame 103 and the second connecting frame 104 can form a cross shape.

[0029] A protective cover 101 is fixedly installed on the upper surface of the support base 1, and multiple groups of batteries 108 are arranged in the protective cover 101. The multiple groups of batteries 108 can act as a counterweight for the support base 1, so that the unfolded first connecting frame 103 and the second connecting frame 104 can remain stable and not fall over when being pushed and rotated by the following mechanism 2.

[0030] Through the design of the support base 1, the triangular box 102, the first connecting frame 103, the second connecting frame 104, the following mechanism 2, the sweeping mechanism 3 and the locking mechanism 4, when in use, the staff can flip and unfold the four groups of second connecting frames 104 in sequence, and in the process of flipping and unfolding, the locking sleeve end of the locking mechanism 4 can be used to lock the outer surface of the locked sleeve end of the locking mechanism 4 set on the upper surface of the second connecting frame 104, so that the second connecting frame 104 can be locked and pulled to be flush with the first connecting frame 103 and form a cross shape, so that the second connecting frame 104 can drive the photovoltaic panels on the surface to flip and unfold together, and then the flipped photovoltaic panels can be pushed or pulled by the following mechanism 2 to perform tilt and horizontal rotation operations, so that the photovoltaic panels can be adjusted in real time according to the angle of the sun. The photovoltaic panel is adjusted to ensure that it always faces the sun. According to the photovoltaic effect, when the photovoltaic panel is perpendicular to the sunlight, it can absorb sunlight to the maximum extent, thereby improving the photoelectric conversion efficiency. Compared with the photovoltaic panel system with a fixed angle, this adjustable design can greatly reduce the energy loss caused by the undesirable incident angle of light, and effectively improve the power generation capacity per square meter of land. The horizontal rotation allows the position of the photovoltaic panel to be adjusted after installation, and after long-term use, the brushing mechanism 3 can be started to brush off the floating dust on the surface of the photovoltaic panel, thereby preventing dust from blocking sunlight from shining on the surface of the photovoltaic panel, and dust will reduce the light intensity reaching the active layer of the photovoltaic panel. After removing the floating dust through the brushing mechanism 3, the photoelectric conversion efficiency of the photovoltaic panel can be maintained at a high level, ensuring a stable power generation.

[0031] like Figure 3-Figure 4 As shown, the locking mechanism 4 includes four groups of lock buckles 401, which are fixedly mounted on the upper surface of the first connecting plate 106 at the four corners of the first connecting frame 103. A Y-shaped locking sleeve 402 is rotatably mounted inside the lock buckle 401. The Y-shaped locking sleeve 402 can be locked on the outer surface of the locking tongue 403. The locking tongue 403 is fixedly mounted on the upper surface of the second connecting plate 105, so that the second connecting frame 104 can be locked by the Y-shaped locking sleeve 402 through the locking tongue 403, so that the four groups of second connecting frames 104 can be locked and pulled to be flush with the first connecting frame 103 to form a cross shape.

[0032] Through the design of the lock buckle 401, Y-shaped lock sleeve 402 and lock tongue 403, during transportation, the four groups of second connecting frames 104 can be flipped and folded to form a square frame, thereby reducing the floor space and space occupied. When in use, the four groups of second connecting frames 104 can be flipped and unfolded in turn, and during the flipping and unfolding process, the Y-shaped lock sleeve 402 of the four corner lock buckles 401 of the first connecting frame 103 can be used to cover the outer surface of the lock tongue 403 at one end of the flipped and unfolded second connecting frame 104, so that the four groups of second connecting frames 104 can be locked and pulled to be flush with the first connecting frame 103 to form a cross-shaped unfolding, wherein the second connecting frame 104 can be flush with the first connecting frame 103 to form a cross-shaped unfolding through a simple flipping and unfolding operation. This operation is relatively simple and does not require complicated assembly tools or a large amount of manpower. At the construction site, the simple and convenient unfolding operation can save time, increase the deployment speed of the equipment, and enable the device to be put into use faster.

[0033] like Figure 5-Figure 7 As shown, the following mechanism 2 includes a rotating rod 201, which is rotatably mounted in a U-shaped frame 107, and the U-shaped frame 107 is fixedly mounted at one end of the first connecting frame 103. A rack 202 is fixedly mounted on one end of the outer surface of the rotating rod 201, and the other end of the rack 202 slides in a guide cylinder 203, and the guide cylinder 203 is rotatably mounted in the triangular box 102. A first motor 204 is fixedly mounted on one end of the guide cylinder 203, and the output shaft of the first motor 204 passes through the guide cylinder 203 and a first gear 205 is fixedly mounted on the end, and the first gear 205 is meshed with the rack 202.

[0034] The first motor 204 can drive the first gear 205 to engage the transmission rack 202, so that the rack 202 can be pulled to slide in the guide cylinder 203, thereby enabling the rack 202 to push or pull the first connecting frame 103 to rotate at one end of the triangular box 102.

[0035] A mounting plate 110 is fixed at one end of the upper surface of the support seat 1, and a second motor 206 is fixedly installed on the lower surface of the mounting plate 110. The output shaft of the second motor 206 passes through the upper surface of the mounting plate 110 and a second gear 207 is fixedly installed at the end. The second gear 207 is meshed with a gear ring 208, and the gear ring 208 is fixedly installed on the lower surface of the triangular box 102.

[0036] The second motor 206 can drive the second gear 207 to engage the transmission ring gear 208, so that the ring gear 208 can drive the triangular box 102 to rotate on the upper surface of the support seat 1 through the connecting column 109 on the lower surface, and then the triangular box 102 can drive the photovoltaic panels on the first connecting frame 103 and the second connecting frame 104 to rotate horizontally.

[0037] Through the design of the rack 202, the first motor 204, the first gear 205, the second motor 206, the second gear 207 and the gear ring 208, when the inclination of the photovoltaic panels on the first connecting frame 103 and the second connecting frame 104 is adjusted, the first motor 204 can be started to drive the first gear 205 to mesh with the rack 202. According to the transmission principle of the gear rack 202, the rotating first gear 205 will apply a linear thrust or pull to the rack 202, and one end of the rack 202 is fixedly mounted on the outer surface of the rotating rod 201, and the rotating rod 201 is rotatably mounted in the C-shaped frame 107, and the C-shaped frame 107 is fixedly mounted on one end of the first connecting frame 103. Therefore, when the rack 202 slides in the guide cylinder 203, A thrust or pull will be applied to the first connecting frame 103 through the rotating rod 201, and through the action of this force, the first connecting frame 103 will rotate at one end of the triangular box 102 to adjust the inclination, and the first connecting frame 103 is connected to the second connecting frame 104, and the photovoltaic panels are installed on these connecting frames, so as to adjust the inclination of the photovoltaic panels, and then the photovoltaic panels can change their inclination according to factors such as the altitude angle of the sun, so as to better receive sunlight and improve power generation efficiency. In addition, according to the preset algorithm and schedule, the position of the sun can be calculated, and the first motor 204 can be positioned to start and stop to control the inclination and rotation of the photovoltaic panels, so as to ensure that the photovoltaic panels are perpendicular to the sunlight, thereby maximizing the power generation efficiency; When the photovoltaic panel needs to be rotated horizontally, the second motor 206 can be started to drive the second gear 207 to mesh with the gear ring 208. According to the transmission principle of the gear gear ring 208, the second gear 207 driven by the fixed second motor 206 will drive the gear ring 208 to rotate, and the gear ring 208 is fixedly installed on the lower surface of the triangular box 102, and the triangular box 102 is rotatably installed on the upper surface of the support seat 1 through the connecting column 109 on the lower surface, which will drive the triangular box 102 to rotate on the upper surface of the support seat 1. Since the triangular box 102 is connected to the first connecting frame 103 and the second connecting frame 104, it can drive the photovoltaic panels on the first connecting frame 103 and the second connecting frame 104 to rotate horizontally. This horizontal rotation can also allow the photovoltaic panels to be adjusted according to the azimuth of the sun, ensuring that the photovoltaic panels are always facing the sun, further improving the power generation efficiency.

[0038] Among them, this embodiment also includes a controller and a solar tracker. The controller is installed inside the protective cover 101 and is electrically connected to the battery 108. The solar tracker is installed on the second connecting frame 104 and can illuminate the position of the sun, and is used to monitor the position of the sun in real time. The controller is also electrically connected to the solar tracker, the first gear 205 and the second motor 206. The controller cooperates with the solar tracker to control the second motor 206 to automatically adjust the direction and angle of the photovoltaic panel in real time to improve the power generation efficiency of the photovoltaic panel. At the same time, the photovoltaic panel is electrically connected to the battery 108 through the solar controller. The battery 108 is used for energy storage. The controller can use the S7-200 ultra-miniaturized PLC controller, and the controller has a built-in 5G communication module for remote communication to facilitate remote control. The solar tracker can use the SOLYS2 solar tracker model.

[0039] like Figure 8-Figure 9 As shown, the brushing mechanism 3 includes a third motor 301, which is fixedly mounted on one end of a fastening plate 111, which is fixedly mounted on one end of a first connecting frame 103, and an output shaft of the third motor 301 passes through the fastening plate 111 and the photovoltaic panel at one end of the first connecting frame 103, and a transmission column 303 is fixedly mounted on the end of the output shaft of the third motor 301, and a cleaning rod 304 is fixedly mounted on the outer surface of the transmission column 303, and the bristles on the cleaning rod 304 touch the surface of the photovoltaic panel.

[0040] The outer surface of the output shaft of the third motor 301 is covered with a transmission belt 302, and the other end of the transmission belt 302 is covered on the outer surface of the transmission column 303 rotating in the second connecting frame 104, so that the third motor 301 can drive the transmission columns 303 in the first connecting frame 103 and the second connecting frame 104 to rotate together through the transmission belt 302, so that the transmission column 303 drives the cleaning rod 304 to rotate and brush away dust on the surface of the photovoltaic panels of the first connecting frame 103 and the second connecting frame 104.

[0041] Through the design of the third motor 301, the transmission belt 302, the transmission column 303 and the cleaning rod 304, when it is necessary to brush the floating dust on the surface of the photovoltaic panel, the third motor 301 can be started to drive the cleaning rod 304 at one end of the transmission column 303 to rotate on the surface of the photovoltaic panel, so that the bristles on the cleaning rod 304 can touch the surface of the photovoltaic panel to perform a rotational brushing operation. In the process of the third motor 301 driving the transmission column 303 to rotate, the transmission belt 302 mounted on the outer surface of the transmission column 303 is also driven to rotate together, and the other end of the transmission belt 302 is mounted on the outer surface of the transmission column 303 rotatably installed in the four sets of second connecting frames 104, so that the third motor 301 can drive one end of the second connecting frame 104 to rotate together. The cleaning rod 304 rotates and sweeps together, and the rotating brushing method can remove floating dust more effectively than simple wiping, because the rotating action can make the bristles contact with dust particles from different angles, and has a better stripping effect on the dust attached to the surface of the photovoltaic panel, ensuring that the dust can be completely removed, and a third motor 301 drives multiple cleaning rods 304 to work, reducing the number of required third motors 301. Compared with the design of equipping each cleaning rod 304 with a separate motor, this centralized driving method not only simplifies the equipment structure, but also is more efficient when starting the cleaning operation. There is no need to control multiple motors separately, reducing the complexity of control, but also reducing the starting and running time of the motor, thereby improving the overall cleaning efficiency.

[0042] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when in use, the staff can turn over and unfold the four groups of second connecting frames 104 in sequence, and in the process of turning over and unfolding, the Y-shaped lock sleeves 402 of the four corner lock buckles 401 of the first connecting frame 103 can be used to cover the outer surface of the lock tongue 403 at one end of the turned and unfolded second connecting frame 104, so that the four groups of second connecting frames 104 can be locked and pulled to be flush with the first connecting frame 103 to form a cross-shaped unfolding. Subsequently, when it is necessary to adjust the inclination of the photovoltaic panels on the first connecting frame 103 and the second connecting frame 104, the first motor 204 can be started to drive the first gear 205 to mesh with the rack 202. According to the transmission principle of the gear rack 202, the first gear 205 rotates 05 will apply a linear thrust or pull to the rack 202, and one end of the rack 202 is fixedly mounted on the outer surface of the rotating rod 201, and the rotating rod 201 is rotatably mounted in the U-shaped frame 107, and the U-shaped frame 107 is fixedly mounted on one end of the first connecting frame 103. Therefore, when the rack 202 slides in the guide cylinder 203, a thrust or pull will be applied to the first connecting frame 103 through the rotating rod 201, and through the action of this force, the first connecting frame 103 will perform a rotational inclination adjustment operation at one end of the triangular box 102, and the first connecting frame 103 is connected to the second connecting frame 104, and the photovoltaic panels are mounted on these connecting frames, thereby realizing the adjustment of the inclination of the photovoltaic panels, and the solar panel can also be calculated according to the preset algorithm and schedule. The first motor 204 is positioned to start and stop the tilting and rotating of the photovoltaic panel, thereby ensuring that the photovoltaic panel is perpendicular to the sunlight, thereby maximizing the power generation efficiency. When the photovoltaic panel needs to be rotated horizontally, the second motor 206 can be started to drive the second gear 207 to mesh with the gear ring 208. According to the transmission principle of the gear gear ring 208, the second gear 207 driven by the fixedly installed second motor 206 will drive the gear ring 208 to rotate, and the gear ring 208 is fixedly installed on the lower surface of the triangular box 102. The triangular box 102 is rotatably installed on the upper surface of the support seat 1 through the connecting column 109 on the lower surface, which will drive the triangular box 102 to rotate on the upper surface of the support seat 1. Since the triangular box 102 is connected to the first connecting frame 103 and the second The connecting frame 104 is connected to each other, and can drive the photovoltaic panels on the first connecting frame 103 and the second connecting frame 104 to perform horizontal rotation operations. This horizontal rotation can also allow the photovoltaic panels to be adjusted according to the azimuth of the sun, ensuring that the photovoltaic panels are always facing the sun, further improving the power generation efficiency. When it is necessary to brush the floating dust on the surface of the photovoltaic panel, the third motor 301 can be started to drive the cleaning rod 304 at one end of the transmission column 303 to rotate on the surface of the photovoltaic panel, so that the bristles on the cleaning rod 304 can touch the surface of the photovoltaic panel for a rotational brushing operation. In the process of the third motor 301 driving the transmission column 303 to rotate, it will also drive the transmission belt 302 on the outer surface of the transmission column 303 to rotate together.The other end of the transmission belt 302 is sleeved on the outer surface of the transmission column 303 rotatably installed in the four sets of second connecting frames 104, so that the third motor 301 can drive the cleaning rod 304 at one end of the second connecting frame 104 to rotate and sweep together. Compared with simple wiping, the rotating brushing method can more effectively remove floating dust, because the rotating action can make the bristles contact with dust particles from different angles, which has a better stripping effect on the dust attached to the surface of the photovoltaic panel, ensuring that the dust can be completely removed, thereby improving the overall cleaning efficiency.

[0043] In summary: the device enables the photovoltaic panels to be adjusted in real time according to the angle of the sun, ensuring that the photovoltaic panels are always facing the sun. According to the photovoltaic effect, when the photovoltaic panels are perpendicular to the sunlight, they can absorb sunlight to the maximum extent, thereby improving the photoelectric conversion efficiency. Compared with the photovoltaic panel system with a fixed angle, this adjustable design can greatly reduce the energy loss caused by the undesirable incident angle of light, effectively improving the power generation capacity per square meter of land, and after long-term use, the cleaning rod 304 can also be used to brush off the floating dust on the surface of the photovoltaic panel, thereby preventing dust from blocking sunlight from shining on the surface of the photovoltaic panel, and dust will reduce the light intensity reaching the active layer of the photovoltaic panel. After removing the floating dust through the brushing mechanism 3, the photoelectric conversion efficiency of the photovoltaic panel can be maintained at a high level, ensuring stable power generation.
