Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and specifically relates to a ground photovoltaic power generation array module. Background Art

[0002] Ground-mounted photovoltaic array modules are a crucial component of photovoltaic power generation systems, utilizing the photoelectric conversion effect to convert solar energy into direct current (DC) electricity. PV modules, the basic unit of a PV array module, consist of multiple solar cells that convert solar energy into DC electricity. Because the amount of energy a single PV panel can convert is extremely limited, and a single panel cannot fully utilize sunlight, PV array modules are often used to meet power generation needs in ground-mounted photovoltaic power generation systems.

[0003] Conventional photovoltaic array modules are mainly composed of photovoltaic panels and brackets. An array module is formed by connecting multiple photovoltaic panels and brackets. In actual use, due to the large area and the photovoltaic panels are directly exposed to the outside, the surface of the array module is easily contaminated with dust, and excessive dust will have a significant impact on the power generation efficiency. In the existing technology, the surface of the photovoltaic panels is generally cleaned regularly by manual water pipes, but due to the large overall area, the cleaning efficiency is low, and a lot of manpower and material resources are required to complete the maintenance, which is in urgent need of improvement.

[0004] At the same time, although conventional photovoltaic array modules are installed in unobstructed areas as much as possible, in actual use, the angles of some photovoltaic panels will still be blocked to a certain extent. The photovoltaic array modules in the existing technology can generally only adjust the overall support angle, and cannot fine-tune the angle of a single photovoltaic panel to avoid obstruction of radiation. The practicality needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide a ground photovoltaic power generation array module to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a ground photovoltaic power generation array module, comprising a base, the top of the base is provided with guide grooves at equal distances, the top of the base is provided with photovoltaic power generation components at equal distances, and every two adjacent photovoltaic power generation components are staggered diagonally, and mounting seats are fixedly installed on the left and right sides of the top of the base at equal distances, a rotating shaft is fixedly sleeved inside the mounting seat, the photovoltaic power generation components and the rotating shaft are movably sleeved, the photovoltaic power generation components rotate relative to the rotating shaft, the rear ends of every two photovoltaic power generation components are connected by a connecting plate, and a cleaning component is fixedly installed at equal distances between the left and right connecting plates, the bottom end of the base is provided with through grooves at equal distances, the bottom end of the cleaning component passes through the through grooves and is connected to an external water pipe, a clean water tank is provided above the base, the bottom end of the clean water tank is fixedly connected to a pressure pipe at equal distances, the bottom end of the pressure pipe is connected to the cleaning component, and the bottom end of the clean water tank is provided with a matrix-shaped nozzle located above the photovoltaic power generation component;

[0007] The photovoltaic power generation component includes a photovoltaic power generation panel, the bottom end of the photovoltaic power generation panel is movably connected between the machine base and the rotating shaft, the mounting seat is located at the front and rear sides of the machine base at the bottom end of the photovoltaic power generation panel, and the photovoltaic power generation panel can rotate relative to the middle of the machine base.

[0008] During actual use, the base can be fixed to the flat ground. The specific number of arrays can be selected according to actual needs. The bottom end of the cleaning component can be connected to the external clean water pipe. At the same time, the device can be connected to the power supply after passing through the inverter to ensure normal power supply of the device.

[0009] As a further technical solution of the present invention, extension seats are installed diagonally symmetrically on the left and right sides of the base, and cylinders are fixedly installed on the inner side of the extension seats. The two cylinders are respectively located in the middle position of the array composed of left and right photovoltaic power generation components, and the output ends of the cylinders are connected to the corresponding photovoltaic power generation components.

[0010] The cylinder can output power to the photovoltaic power generation component. The cylinder on the left can provide power to the array module installed on the right, and the output power is located in the middle of the array module. The cylinder on the right can provide power to the array module installed on the left, and the output power is also located in the middle of the array module.

[0011] As a further technical solution of the present invention, a locking block is fixedly installed in the middle of the back of the photovoltaic panel, and the photovoltaic power generation assembly also includes a fixing plate located on the back of the locking block. The fixing plate is fixedly connected to a locking seat at one end close to the locking block. The locking block is movably connected to the locking seat through a connecting shaft, and the locking block rotates relative to the locking seat.

[0012] As a further technical solution of the present invention, a first fixed seat is fixedly installed in the middle of the fixed plate away from the locking seat, the first fixed seat is movably connected to a support rod at one end away from the fixed plate through a rotating shaft, the support rod is movably connected to a second fixed seat at one end away from the first fixed seat through a rotating shaft, and the bottom end of the second fixed seat is fixedly connected to a guide block.

[0013] As a further technical solution of the present invention, the guide block is movably connected to the guide groove, every two adjacent guide blocks are connected to the connecting plate, and the end face of the guide block in the middle is connected to the output end of the cylinder.

[0014] When the irradiation angle of the photovoltaic panel needs to be changed, the two cylinders can be opened. When the two cylinders are shortened, the two pulling connecting plates are displaced toward the middle of the base, and the distance between the two connecting plates is reduced. At the same time, the guide block is displaced toward the middle of the base. At this time, the support rod is deflected downward, and the photovoltaic panel is subjected to a downward pulling force. At this time, the photovoltaic panel can rotate relative to the rotating shaft, that is, the angle between the photovoltaic panel and the base is reduced. At this time, the photovoltaic panel can adapt to the sunlight at a high altitude and complete the adaptive adjustment process. At this time, the left and right groups of photovoltaic power generation component arrays can complete the adjustment synchronously and adapt to the midday sunlight at the same time.

[0015] By staggering and equidistantly distributing multiple photovoltaic power generation components, when adjusting the light angle, two symmetrically arranged array modules can be adjusted at the same time without interfering with each other, so that both can have smaller support angles at noon, so that both can fully absorb light and improve power generation efficiency. At the same time, the staggered and symmetrically distributed photovoltaic power generation components can also reduce their footprint, so that more photovoltaic power generation components can be installed as much as possible in a limited space, thereby improving the overall power generation efficiency of the array module.

[0016] As a further technical solution of the present invention, the cleaning component includes a water storage pipe, and a water inlet valve is fixedly connected to the middle of the bottom end of the outer side surface of the water storage pipe. The bottom end of the water inlet valve passes through the bottom end of the base and is connected to the external water pipe. The middle part of the top end of the outer side surface of the water storage pipe is fixedly connected to the drain valve, and the top end of the drain valve is connected to the bottom end of the pressure pipe.

[0017] As a further technical solution of the present invention, piston plates are movably connected on both sides of the front and rear sides of the inner cavity of the water storage pipe, and the relatively far ends of the two piston plates are fixedly connected to piston rods, and the end of the piston rod away from the piston plate passes through one side of the water storage pipe and is connected to the connecting plate.

[0018] As a further technical solution of the present invention, a one-way valve is installed inside the water inlet valve and the drain valve, and the directions of the valves are respectively to conduct to the inside of the water storage pipe and to block outside the water storage pipe, and to conduct to the outside of the water storage pipe and to block inside the water storage pipe.

[0019] When adjusting the illumination angle of multiple photovoltaic power generation modules, that is, reducing the support angle to adapt to the midday sun, the two connecting plates are relatively close to each other, which can apply pressure to the two piston rods. At this time, the two piston plates are relatively close to each other and apply pressure to the clean water inside the water storage pipe. At this time, the clean water is discharged through the drain valve under pressure, rises through the pressure pipe into the inside of the clean water tank, and is discharged through multiple nozzles. At this time, the clean water can act on the surface of the photovoltaic power generation module, realizing automatic cleaning of the surface of the photovoltaic panel;

[0020] When the support angle of the photovoltaic power generation component increases, the two connecting plates can be relatively separated, which can drive the two piston plates to be relatively separated. At this time, negative pressure can be generated inside the water storage pipe, and water can be sucked from the external water pipe into the water storage pipe through the water inlet valve for temporary storage for use in the next cleaning.

[0021] By utilizing the support angle adjustment process of the photovoltaic power generation component, the two connecting plates are brought closer to each other, and the automatic spraying of clean water is achieved through the function of the cleaning component to complete the automatic cleaning process. At the same time, when the support angle of the photovoltaic power generation component is increased, the clean water inside the cleaning component can also be replenished. The entire process is completed automatically without manual control, effectively improving the cleaning efficiency and providing the best conversion efficiency when the light intensity is maximum.

[0022] As a further technical solution of the present invention, a half gear is fixedly sleeved on the outer side surface of the locking block near one end of the locking seat, a slot is opened on the end of the fixing plate near the locking block, a block is movably connected to the inside of the slot, and micro electric push rods are installed on the left and right sides of the inner cavity of the slot, and the output end of the micro electric push rod is connected to one side of the block.

[0023] As a further technical solution of the present invention, one end of the card block close to the locking block is fixedly connected to a rack located below the half gear, and the half gear and the rack are meshed together. When the locking block and the locking seat are parallel to each other, the rack is located in the middle position of the half gear.

[0024] When the surface of a single photovoltaic panel encounters an obstruction and needs to be adjusted, the corresponding micro-electric push rod can be turned on to push the card block to move relative to the card slot. At this time, the rack at the top will also move relative to the half gear. Since the two are engaged with each other, when the rack moves left and right, the half gear will rotate accordingly, and drive the locking block to rotate relative to the locking seat. At this time, the photovoltaic panel can be adjusted synchronously, that is, the photovoltaic panel swings relative to the base at the bottom to complete the angle fine-tuning to avoid obstruction.

[0025] By hingedly connecting the locking block and the locking seat, the photovoltaic panel can not only adjust the support angle, but also swing relative to the bottom base, so that the photovoltaic panel can be actively adjusted to avoid obstruction in local areas, effectively avoiding the problem of traditional devices caused by obstruction in local areas, resulting in a decrease in power generation efficiency, and significantly improving the overall power generation efficiency.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The present invention utilizes the support angle adjustment process of the photovoltaic power generation component to achieve the mutual proximity of the two connecting plates, and realizes the automatic spraying of clean water through the action of the cleaning component to complete the automatic cleaning process. At the same time, when the support angle of the photovoltaic power generation component is increased, the clean water inside the cleaning component can also be replenished. The whole process is completed automatically without manual control, effectively improving the cleaning efficiency and providing the best conversion efficiency when the light intensity is maximum.

[0028] 2. The present invention hinges the locking block and the locking seat so that the photovoltaic panel can not only adjust the support angle, but also swing relative to the bottom base, so that the photovoltaic panel can be actively adjusted to avoid obstruction in local areas, effectively avoiding the problem of traditional devices caused by obstruction in local areas, resulting in a decrease in power generation efficiency, and significantly improving the overall power generation efficiency.

[0029] 3. The present invention distributes multiple photovoltaic power generation components in an equidistant and staggered manner, so that when adjusting the illumination angle, two symmetrically arranged array modules can be adjusted at the same time without interfering with each other, so that both can have smaller support angles at noon, so that both can fully absorb sunlight and improve power generation efficiency. At the same time, the staggered and symmetrically distributed photovoltaic power generation components can also reduce their footprint, so that more photovoltaic power generation components can be installed as much as possible in a limited space, thereby improving the overall power generation efficiency of the array module.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0041] The photovoltaic power generation component 12 includes a photovoltaic power generation panel 121. The bottom end of the photovoltaic power generation panel 121 is movably connected between the machine base and the rotating shaft 11. The mounting seat 10 is located on the front and rear sides of the machine base at the bottom end of the photovoltaic power generation panel 121, and the photovoltaic power generation panel 121 can rotate relative to the middle of the machine base.

[0042] In actual use, the base 1 can be fixed to the flat ground, and the specific number of arrays can be selected according to actual needs. The bottom end of the cleaning component 6 can be connected to the external clean water pipe, and the device can be connected to the power supply after passing through the inverter to ensure normal power supply of the device.

[0043] like Figure 1 and Figure 2 as well as Figure 5 As shown, the left and right sides of the base 1 are diagonally symmetrically installed with extension seats 3, and the inner side of the extension seat 3 is fixedly installed with a cylinder 4. The two cylinders 4 are respectively located in the middle position of the array composed of the left and right photovoltaic power generation components 12, and the output end of the cylinder 4 is connected to the corresponding photovoltaic power generation component 12.

[0044] The cylinder 4 can output power to the photovoltaic power generation component 12. The cylinder 4 on the left can provide power to the array module installed on the right, and the output power is located in the middle of the array module. The cylinder 4 on the right can provide power to the array module installed on the left, and the output power is also located in the middle of the array module.

[0045] like Figure 4 and Figure 7 as well as Figure 8As shown, a locking block 122 is fixedly installed in the middle of the back of the photovoltaic power generation panel 121, and the photovoltaic power generation assembly 12 also includes a fixing plate 124 located on the back of the locking block 122. The fixing plate 124 is fixedly connected to a locking seat 123 at one end close to the locking block 122. The locking block 122 is movably connected to the locking seat 123 through a connecting shaft. The locking block 122 rotates relative to the locking seat 123. The middle of the fixing plate 124 away from the locking seat 123 is fixedly installed with a first fixing seat 1210. The first fixing seat One end of 1210 away from the fixed plate 124 is movably connected to the support rod 1212 through a rotating shaft, and one end of the support rod 1212 away from the first fixed seat 1210 is movably connected to the second fixed seat 1211 through a rotating shaft. The bottom end of the second fixed seat 1211 is fixedly connected to a guide block 1213, and the guide block 1213 is movably engaged with the guide groove 2. Every two adjacent guide blocks 1213 are connected to the connecting plate 5, and the end face of the middle guide block 1213 is connected to the output end of the cylinder 4.

[0046] When it is necessary to change the illumination angle of the photovoltaic panel 121, the two cylinders 4 can be opened. When the two cylinders 4 are shortened, the two pulling connecting plates 5 are displaced toward the middle of the base 1, and the distance between the two connecting plates 5 is reduced. At the same time, the guide block 1213 is displaced toward the middle of the base 1. At this time, the support rod 1212 is deflected downward. At this time, the photovoltaic panel 121 is subjected to a downward pulling force. At this time, the photovoltaic panel 121 can rotate relative to the rotating shaft 11, that is, the angle between the photovoltaic panel 121 and the base 1 is reduced. At this time, the photovoltaic panel 121 can adapt to the sunlight at a high altitude and complete the adaptive adjustment process. At this time, the left and right groups of photovoltaic power generation components 12 arrays can complete the adjustment synchronously and adapt to the midday sunlight at the same time.

[0047] By staggering and equidistantly distributing multiple photovoltaic power generation components 12, when adjusting the light angle, two symmetrically arranged array modules can be adjusted at the same time without interfering with each other, so that the support angle of both can be reduced at noon, so that both can fully absorb light and improve power generation efficiency. At the same time, the staggered and symmetrically distributed photovoltaic power generation components 12 can also reduce their footprint, so that more photovoltaic power generation components 12 can be installed as much as possible in a limited space, thereby improving the overall power generation efficiency of the array module.

[0048] like Figure 3 and Figure 4 and Figure 5 as well as Figure 6As shown, the cleaning component 6 includes a water storage pipe 601, and a water inlet valve 602 is fixedly connected to the middle of the bottom end of the outer side surface of the water storage pipe 601. The bottom end of the water inlet valve 602 passes through the bottom end of the base 1 and is connected to the external water pipe. The middle part of the top end of the outer side surface of the water storage pipe 601 is fixedly connected to the drain valve 603, and the top end of the drain valve 603 is connected to the bottom end of the pressure pipe 9. The front and rear sides of the inner cavity of the water storage pipe 601 are movably sleeved with piston plates 604, and the relatively far ends of the two piston plates 604 are fixedly connected to piston rods 605. The end of the piston rod 605 away from the piston plate 604 passes through one side of the water storage pipe 601 and is connected to the connecting plate 5. A one-way valve is installed inside the water inlet valve 602 and the drain valve 603, and the directions of the valves are respectively to conduct to the inside of the water storage pipe 601 and cut off to the outside of the water storage pipe 601, and to conduct to the outside of the water storage pipe 601 and cut off to the inside of the water storage pipe 601.

[0049] Example: When adjusting the illumination angle of multiple photovoltaic power generation components 12, that is, reducing the support angle to adapt to the midday sun, the two connecting plates 5 are relatively close to each other, so that they can apply pressure to the two piston rods 605. At this time, the two piston plates 604 are relatively close to each other and apply pressure to the clean water inside the water storage pipe 601. At this time, the clean water is discharged through the drain valve 603 under pressure, and rises through the pressure pipe 9 into the interior of the clean water tank 7, and is discharged through the multiple nozzles 8. At this time, the clean water can act on the surface of the photovoltaic power generation component 12, realizing automatic cleaning of the surface of the photovoltaic power generation panel 121;

[0050] When the support angle of the photovoltaic power generation component 12 increases, the two connecting plates 5 can be relatively separated, which can drive the two piston plates 604 to be relatively separated. At this time, negative pressure can be generated inside the water storage pipe 601, and water can be sucked from the external water pipe into the interior of the water storage pipe 601 through the water inlet valve 602 for temporary storage for use in the next cleaning.

[0051] By utilizing the support angle adjustment process of the photovoltaic power generation component 12, the two connecting plates 5 are brought closer to each other, and the automatic spraying of clean water is achieved through the action of the cleaning component 6, completing the automatic cleaning process. At the same time, when the support angle of the photovoltaic power generation component 12 is increased, the clean water inside the cleaning component 6 can also be replenished. The entire process is completed automatically without manual control, effectively improving the cleaning efficiency and providing the best conversion efficiency when the light intensity is maximum.

[0052] like Figure 7 and Figure 8As shown, the outer side surface of the locking block 122 near one end of the locking seat 123 is fixedly sleeved with a half gear 129, and a fixing plate 124 is provided with a slot 125 at one end near the locking block 122. The internal movability of the slot 125 is connected with a block 126, and micro-electric push rods 127 are installed on the left and right sides of the inner cavity of the slot 125. The output end of the micro-electric push rod 127 is connected to one side of the block 126, and the end of the block 126 near the locking block 122 is fixedly connected with a rack 128 located below the half gear 129. The half gear 129 and the rack 128 are meshed and connected. When the locking block 122 and the locking seat 123 are parallel to each other, the rack 128 is located in the middle position of the half gear 129.

[0053] Embodiment: When the surface of a single photovoltaic panel 121 encounters an obstruction and needs to be adjusted, the corresponding micro-electric push rod 127 can be turned on to push the block 126 to displace relative to the slot 125. At this time, the rack 128 at the top is displaced relative to the half gear 129. Since the two are engaged with each other, when the rack 128 is displaced left and right, the half gear 129 rotates accordingly and drives the locking block 122 to rotate relative to the locking seat 123. At this time, the photovoltaic panel 121 can be adjusted synchronously, that is, the photovoltaic panel 121 swings relative to the base at the bottom to complete the angle fine-tuning and avoid obstruction.

[0054] By hingedly connecting the locking block 122 and the locking seat 123, the photovoltaic panel 121 can not only adjust the support angle, but also swing relative to the bottom base, so that the photovoltaic panel 121 can be actively adjusted to avoid obstruction in local areas, effectively avoiding the problem of traditional devices being blocked in local areas, resulting in a decrease in power generation efficiency, and significantly improving the overall power generation efficiency.

[0055] Working principle and usage process:

[0056] When the irradiation angle of the photovoltaic panel 121 needs to be changed, the two cylinders 4 can be opened. When the two cylinders 4 are shortened, the two pulling connecting plates 5 are displaced toward the middle of the base 1, and the distance between the two connecting plates 5 is reduced. At the same time, the guide block 1213 is displaced toward the middle of the base 1. At this time, the support rod 1212 is deflected downward. At this time, the photovoltaic panel 121 is subjected to a downward pulling force. At this time, the photovoltaic panel 121 can rotate relative to the rotating shaft 11, that is, the angle between the photovoltaic panel 121 and the base 1 is reduced. At this time, the photovoltaic panel 121 can adapt to the sunlight at a high altitude, completing the adaptive adjustment process. At this time, the left and right groups of photovoltaic power generation components 12 arrays can complete the adjustment synchronously and adapt to the midday sunlight at the same time.

[0057] When adjusting the illumination angle of the multiple photovoltaic power generation components 12, that is, reducing the support angle to adapt to the midday sun, the two connecting plates 5 are relatively close to each other, so that they can apply pressure to the two piston rods 605. At this time, the two piston plates 604 are relatively close to each other, and apply pressure to the clean water inside the water storage pipe 601. At this time, the clean water is discharged through the drain valve 603 under pressure, and rises through the pressure pipe 9 into the interior of the clean water tank 7, and is discharged through the multiple nozzles 8. At this time, the clean water can act on the surface of the photovoltaic power generation components 12, realizing automatic cleaning of the surface of the photovoltaic power generation panels 121;

[0058] When the support angle of the photovoltaic power generation assembly 12 increases, the two connecting plates 5 can move relatively apart, which can drive the two piston plates 604 to move relatively apart. At this time, negative pressure can be generated inside the water storage pipe 601, and water can be sucked from the external water pipe into the water storage pipe 601 through the water inlet valve 602 for temporary storage for the next cleaning.

[0059] When the surface of a single photovoltaic panel 121 encounters an obstruction and needs to be adjusted, the corresponding micro-electric push rod 127 can be turned on to push the block 126 to move relative to the slot 125. At this time, the rack 128 at the top is displaced relative to the half gear 129. Since the two are engaged with each other, when the rack 128 moves left and right, the half gear 129 rotates accordingly, and drives the locking block 122 to rotate relative to the locking seat 123. At this time, the photovoltaic panel 121 can be adjusted synchronously, that is, the photovoltaic panel 121 swings relative to the base at the bottom to complete the angle fine-tuning and avoid obstruction.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
