Description

Technical Field

[0001] The present invention relates to the field of photovoltaic fences, and in particular to a photovoltaic fence supporting device and an adjusting method. Background Art

[0002] With the development of photovoltaic technology, photovoltaic power generation technology has been applied in different fields, such as photovoltaic fences that combine solar photovoltaic power generation technology with the functions of traditional fences. Similar to ordinary fences, photovoltaic fences play the role of dividing areas and providing safety protection, but the difference is that they have the ability to generate photovoltaic power. By installing photovoltaic modules (hereinafter referred to as photovoltaic panels) on the fence, solar energy can be converted into electrical energy, achieving energy self-sufficiency or connecting to the power grid to obtain benefits, which has both practical value and environmental benefits.

[0003] When building a photovoltaic fence, in order to ensure the overall stability, a concrete building foundation is usually used, and then the supporting structure is installed on the foundation. The supporting structure is generally made of metal materials, such as steel, which has high strength and corrosion resistance. Finally, the core components for photovoltaic power generation (monocrystalline silicon, polycrystalline silicon and thin-film solar cell modules) are installed on the supporting structure and connected together in series and parallel to form a power generation array. At the same time, the inverter, controller, cable and other parts are installed on the supporting structure or in an appropriate position.

[0004] Although photovoltaic walls can make full use of idle wall space for photovoltaic power generation, convert solar energy into electrical energy, and achieve additional energy output, they also have some defects.

[0005] For example, because there are many photovoltaic panels densely laid on the photovoltaic fence, and the photovoltaic panels are in a stable installation state relative to the supporting structure, their position is inconvenient to adjust according to needs, and even their inclination angle and orientation are difficult to change. In addition, because photovoltaic fences are usually in an open outdoor environment, they are easily affected by winds of different directions and intensities. When designing traditional supporting structures, the characteristics and changes of wind in different regions are often not fully considered. When encountering strong winds, due to the large area of ​​photovoltaic panels, the wind load on the windward side increases. If the structural strength and stability of the supporting structure are insufficient, the photovoltaic panels may shake, shift or even fall off, causing equipment damage and safety hazards. Especially in coastal areas or windy areas, frequent strong winds pose a severe challenge to the wind resistance and stability of photovoltaic fences. Summary of the invention

DETAILED DESCRIPTION

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The following is a further description with reference to the accompanying drawings and specific embodiments: Embodiment 1

[0039] In order to be able to adjust the position of photovoltaic panels in strong wind weather, reduce the contact area between strong wind and photovoltaic fence, thereby reducing the chance of photovoltaic panels shaking, shifting or even falling off, and improve the ability of photovoltaic fence to withstand strong wind, this embodiment provides a new support device for photovoltaic fence.

[0040] like Figure 1 , Figure 2 , Figure 5As shown, specifically, the supporting device includes a vertical frame 2, an annular belt 4, a brake mechanism 5, an electrical control box, etc., and a plurality of photovoltaic panels 1 are connected and adjustable on the side of the vertical frame 2 through a bottom frame 16, and the plurality of photovoltaic panels 1 are arranged in an upper and lower distribution, and the bottom frame 16 of the photovoltaic panel 1 on the lower side is stably connected to the vertical frame 2 through bolts. In addition, the annular belt 4 is arranged on the inner side of the vertical frame 2 along the height direction of the vertical frame 2, and is connected to multiple sets of bottom frames 16. In addition, the annular belt 4 can be moved downward relative to the bottom frame 16. Therefore, under the action of the annular belt 4, the plurality of photovoltaic panels 1 can be distributed and stably arranged on the side of the vertical frame 2 under the action of the bottom frame 16. At the same time, the bottom frame 16 adjustable relative to the vertical frame 2 can be controlled in strong wind weather to drive the photovoltaic panel 1 to descend, thereby making the plurality of photovoltaic panels 1 stacked and arranged, reducing the area of ​​the photovoltaic fence and reducing the impact of strong wind on the photovoltaic fence. When the plurality of photovoltaic panels 1 are arranged in an upper and lower distribution, the annular belt 4 can be controlled to be stationary through the action of the brake mechanism 5, so as to achieve stable installation of the photovoltaic panel 1. When the supporting device is used to support photovoltaic panels 1 (commonly single crystal silicon, polycrystalline silicon and thin film solar cells) to form a photovoltaic fence, multiple sets of vertical frames 2 are arranged side by side. Other photovoltaic power generation devices (such as inverters, controllers, cables) can also be installed on the supporting device.

[0041] like Figure 4 , Figure 7 As shown, in order to make the base frame 16 adjustable relative to the vertical frame 2, a sleeve frame 18 is fixedly provided on the side of the base frame 16, and the sleeve frame 18 is sleeved on the vertical pipe 21 of the vertical frame 2. Therefore, with the cooperation of the vertical pipe 21 and the sleeve frame 18, the base frame 16 is stably and movably installed relative to the vertical frame 2.

[0042] like Fig. 9 , Fig.10 As shown, in order to connect the base frame 16 with the annular belt 4, a notch 17 is provided on the side wall of the base frame 16 away from the photovoltaic panel 1, and a first clamping plate 441 and a second clamping plate 442 are provided on both sides of the base frame 16 by bolts, and the second clamping plate 442 is provided at the opening of the notch 17, so the second clamping plate 442 and the notch 17 form a through space, and one side of the annular belt 4 passes through the through space. In addition, a plurality of support plates 43 are provided on the annular belt 4, and the plurality of support plates 43 and the plurality of notches 17 are adapted one by one, so that a support plate 43 is provided under each base frame 16, and under the cooperation of the first clamping plate 441 and the second clamping plate 442, the support plate 43 is in stable contact with the bottom surface of the base frame 16, so that the base frame 16 and the photovoltaic panel 1 are stably installed. The first clamping plate 441 and the second clamping plate 442 form a limiting device 44.

[0043] like Fig. 9 , Fig.10As shown, in order to enable the multiple photovoltaic panels 1 on the upper side to descend when the annular belt 4 rotates, the widths of the multiple support plates 43 and the notch 17 distributed from top to bottom are reduced successively, and at the same time, the sum of the widths of the upper support plate 43 and one side of the annular belt 4 is less than or equal to the width of the space formed by the lower notch 17 and the second clamping plate 442. Therefore, when the annular belt 4 rotates to control the photovoltaic panel 1 and the base frame 16 to descend, the support plate 43 located above the notch 17 can pass through the notch 17, thereby facilitating the stacking of the photovoltaic panels 1 distributed above and below, and avoiding the problem that the annular belt 4 cannot rotate continuously due to the presence of the support plate 43, thereby affecting the stacking of the photovoltaic panels 1.

[0044] like Figure 7 , Figure 8 As shown, in order to stably install the annular belt 4 in the vertical frame 2, connecting devices 42 are provided at the upper and lower ends of the vertical frame 2, and a wheel body 422 is provided on the connecting device 42 through an axle and a bearing, and the two ends of the annular belt 4 are respectively sleeved on the two wheel bodies 422, and the annular belt 4 is in a stretched state. Therefore, under the action of the wheel body 422, the annular belt 4 is stably installed.

[0045] like Figure 7 , Figure 8 As shown, in order to enable the connector 42 to adjust its position according to demand, the connector 42 is sleeved on the top pipe 22 and the bottom pipe at the end of the vertical frame 2, and the side wall of the connector 42 is threaded with a limit bolt 421, and the end of the limit bolt 421 presses against the vertical frame 2. Therefore, the limit of the connector 42 can be released by rotating the limit bolt 421 to achieve the adjustment of the position of the connector 42. The vertical pipe 21, the top pipe 22, and the bottom pipe of the vertical frame 2 can be connected by a plug 23 and a bolt, that is, the plug 23 is welded on the top pipe 22 and the bottom pipe, and the plug 23 is inserted into the vertical pipe 21, and the thread penetrates the vertical pipe 21 and the plug 23. Or the vertical pipe 21, the top pipe 22, and the bottom pipe can also be connected by welding. Regardless of the connection method, when the connector 42 needs to be disassembled, it needs to be cut.

[0046] like Fig.11 As shown, the central axis of the wheel body 422 at the bottom is connected to the power output shaft of the second motor 41. Therefore, the wheel body 422 can be controlled to rotate when the second motor 41 is working, thereby driving the annular belt 4 to rotate forward and reverse, providing support for controlling the base frame 16 to drive the photovoltaic panel 1 to rise and fall. The wheel body 422 can be set as a synchronous wheel, the annular belt 4 can be set as a synchronous belt, and the motor can be set as a servo motor, a stepping motor, etc.

[0047] like Fig.11As shown, in order to keep the endless belt 4 in a stationary state, the brake mechanism 5 is arranged at the lower wheel body 422, and the brake mechanism 5 includes a moving block 52, a brake plate 55, a stud 54 and a third motor 53. The brake plate 55 is arranged on the inner side of the connecting device 42, and the brake plate 55 is arranged near the wheel body 422 and the endless belt 4, and the brake plate 55 can be raised and lowered relative to the connecting device 42. Therefore, under the action of external force, the brake plate 55 can rise to fit the endless belt 4, and press the endless belt 4 and the wheel body 422, so as to apply a large braking force to the endless belt 4 and make the endless belt 4 stationary. In order to control the lifting and lowering of the brake plate 55, an axis body is fixedly arranged below the brake plate 55, and connecting plates 51 are provided at both ends of the axis body through bearing connecting sleeves. The other end of the connecting plate 51 is connected to the side of the moving block 52 through bearings and shafts. The moving block 52 is movably installed at the bottom of the vertical frame 2, and the moving block 52 is threadedly sleeved on the stud 54. At the same time, the end of the stud 54 is connected to the output shaft of the third motor 53. Therefore, when the third motor 53 is working, the moving block 52 can be forced to move through the stud 54 to adjust the inclination angle of the connecting plate 51, thereby controlling the brake plate 55 to rise or fall. When it rises, the annular belt 4 can be braked to keep it still.

[0048] like Fig.12 As shown, in order to stably set the brake plate 55 relative to the connecting device 42, a sliding hole 423 is set on the side wall of the connecting device 42, and the sliding hole 423 is set along the height direction of the connecting device 42. A sliding block 57 is fixedly set at the end of the brake plate 55, and the sliding block 57 is installed in the sliding hole 423, so that the brake plate 55 can be stably connected to the connecting device 42.

[0049] like Fig.13 As shown, in order to enable the moving block 52 to move along the bottom tube of the vertical frame 2, a bar hole 24 and an inlet and outlet groove 25 are provided on the bottom tube, the bar hole 24 is provided along the width direction of the vertical frame 2, and the inlet and outlet groove 25 are provided at the end of the bar hole 24. A connecting plate 56 is fixedly provided below the moving block 52, and the connecting plate 56 passes through the inlet and outlet groove 25 and is installed in the bar hole 24, and can move along the bar hole 24, so that the moving block 52 can be stably and movably installed under the cooperation of the connecting plate 56 and the bar hole 24.

[0050] like Figure 2 , Fig.14As shown, in order to further improve the ability of the device to resist strong winds, a base 3 is also provided at the bottom of the vertical frame 2, and the base 3 includes a fixed ring plate 31 and an adjustable arc plate 32. A plurality of embedded rods 35 are provided below the fixed ring plate 31, and the embedded rods 35 are embedded in the concrete base, so that the base 3 is stably installed and arranged, and the adjustable arc plate 32 is installed at the bottom of the vertical frame 2 to achieve stable installation of the vertical frame 2. In addition, a reinforcing plate is provided on the side of the vertical frame 2 and the adjustable arc plate 32 away from the photovoltaic panel 1, and the reinforcing plate can enhance the ability of the vertical frame 2 to carry the photovoltaic panel 1. The reinforcing plate can be replaced with a drawstring, and the top of the drawstring is connected to the vertical frame 2 by bolts, and the bottom of the drawstring is sleeved on the shaft body, and the shaft body is provided with a ratchet 324 and a brake plate adapted to the ratchet 324, and the drawstring can be contracted by rotating the shaft body, and then the vertical frame 2 is pulled to a better working state under the action of the drawstring.

[0051] like Fig.15 , Fig.16 As shown, the orientation of the photovoltaic panel 1 can also be adjusted by adjusting the position of the photovoltaic panel 1 to further reduce the contact surface between the strong wind and the photovoltaic fence. Specifically, an arc groove 321 is provided on the side wall of the adjustable arc plate 32, and a rack 322 is provided on the inner side of the arc groove 321. The fixed ring plate 31 is sleeved on the outer side of the adjustable arc plate 32, and the fixed ring plate 31 includes a first arc plate 311 and a second arc plate 312 connected by bolts, that is, the bolts penetrate the ear plates 313 of the first arc plate 311 and the second arc plate 312. Gears 315 and multiple rollers 314 are provided on the first arc plate 311 and the second arc plate 312, and the edges of the gears 315 and the rollers 314 are both extended into the arc groove 321, and the gears 315 are meshed and connected with the racks 322, and the central axis of the gears 315 is connected to the power output shaft of the fourth motor 33. With the cooperation of the roller 314 and the gear 315, the adjustable arc plate 32 can be limited to be stably installed in the fixed ring plate 31, and the adjustable arc plate 32 can be controlled to rotate when the gear 315 rotates, thereby adjusting the orientation of the vertical frame 2 and the photovoltaic panel 1, providing support for further reducing the contact surface between strong winds and the photovoltaic fence.

[0052] like Figure 14-16 As shown, in order to make the adjustable arc plate 32 and the fixed ring plate 31 relatively static after relative rotation, a second splicing groove 323 is provided on the outer edge of the adjustable arc plate 32, and an electric cylinder 34 is provided above the second splicing groove 323, and a rod body is provided at the telescopic end of the bottom of the electric cylinder 34, and a plurality of first splicing grooves 316 are provided on the inner edge of the fixed ring plate 31, and the rod body at the bottom of the electric cylinder 34 is inserted into the space formed by the first splicing groove 316 and the second splicing groove 323, so that the rotation of the adjustable arc plate 32 and the fixed ring plate 31 is limited under the action of the rod body. When it is necessary to adjust the direction of the photovoltaic panel 1, the electric cylinder 34 is operated, the rod body is pulled out, and the restrictions on the adjustable arc plate 32 and the fixed ring plate 31 are released.

[0053] In order to be able to adjust the position of the photovoltaic panel 1 in strong wind weather, at least one set of electrical control boxes includes contactors, relays, controllers (such as PLC), human-machine interfaces (such as HMI), power modules, wiring terminals, etc. According to the disclosed technology, the power lines of the motor and electric cylinder are connected to the wiring terminals of the control box, and then connected to the contactor and other devices; the output port of the controller is connected to the negative pole of the contactor coil, the positive pole of the contactor coil is connected to the positive pole of the control power supply, and the controller controls the on and off of the output port through the program, thereby realizing the control of the contactor and the motor; and then the motor is controlled to work together through the control box. In order to obtain instructions to adjust the position of the photovoltaic panel 1, the control box can be connected to the host computer through Ethernet, serial port communication, etc., and then the control center can adjust the position of the photovoltaic panel 1 according to the weather conditions.

[0054] To adjust the position of the photovoltaic panel 1 using the support device, the following steps can be followed: Step 1: The control box installed on the supporting device obtains the command information sent by the host computer.

[0055] Step 2: The control box controls the third motor 53 to rotate, adjusts the position of the moving block 52, and then controls the brake plate 55 to descend, thereby releasing the brake restriction of the endless belt 4.

[0056] Step 3: Then, the control box controls the second motor 41 to rotate, and controls the annular belt 4 to rotate through the wheel body 422. Since the bottom frame 16 and the vertical frame 2 are relatively stationary, the upper frame 16 drives the corresponding photovoltaic panel 1 to descend relative to the vertical frame 2, so that multiple photovoltaic panels 1 and the frame 16 are stacked at the bottom of the vertical frame 2, reducing the impact of strong wind on the supporting device.

[0057] Step 4: The control box can also control the fourth motor 33 to work, control the adjustable arc plate 32 to drive the vertical frame 2 to rotate, and then adjust the direction of the photovoltaic panel 1 to further reduce the impact of strong wind on the supporting device. Embodiment 2

The slide holes 11 are arranged along the tilt direction of the photovoltaic panel 1. Threaded rods 12 are provided on the sides of the slide holes 11. The ends of the threaded rods 12 are connected to the frame of the photovoltaic panel 1 through bearing seats. One threaded rod 12 is connected to the power output shaft of the first motor 13. The first motor 13 is installed on the frame of the photovoltaic panel 1. The two threaded rods 12 are connected by a sprocket and a chain. Therefore, under the action of the first motor 13, the two threaded rods 12 can be controlled to rotate synchronously. A driving column 14 is penetrated through the slide holes 11. The threaded rods 12 are threaded through the driving column 14.
