Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, specifically to a monopile rotating photovoltaic structure. Background Technology

[0002] Existing single-column solar-tracking rotating photovoltaic structures generally use a column and a mounting frame that supports and installs the photovoltaic panels, which are hinged together to form a photovoltaic support structure. By controlling the rotation or flipping of the mounting frame relative to the column, the orientation of the photovoltaic panels can be adjusted, thereby achieving solar tracking. The photovoltaic panels and the mounting frame are generally rectangular in shape with the same area. The photovoltaic panels are connected to the top surface of the mounting frame by fasteners. The bottom of the mounting frame is hinged to a clamp structure set on the side wall of the column by a diagonally set support rod. The column is generally set vertically, and the mounting frame is generally set at a certain angle relative to the column.

[0003] When a single-column rotating photovoltaic (PV) support structure is installed on a slope, stability is generally ensured by increasing the column diameter and burial depth. However, this has a significant impact on the slope excavation area, and the stability needs further improvement. There is also no suitable standing position for installation and maintenance, which affects construction efficiency. In addition, the mounting frame is generally prefabricated according to the preset PV panel area, and the light-receiving area of ​​the PV panel cannot be flexibly adjusted. When the combiner box or power consumption changes on site, the entire PV support structure and PV panels must be replaced, which is costly and has low construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing single-column solar tracking rotating photovoltaic structure, such as the need for further improvement in the stability of the photovoltaic support structure, the lack of suitable construction location for slope installation which affects construction efficiency, the inability to flexibly adjust the light-receiving area of ​​the photovoltaic panel, and the high cost of modification.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0025] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0027] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0028] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0029] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0030] Example 1 like Figures 1-7 As shown, a monopile rotating photovoltaic structure includes a base 1, a column 4, a mounting frame 5, and a photovoltaic panel 6. A limiting cylinder 2 is embedded in the base 1, and the column 4 is disposed in the limiting cylinder 2. The column 4 and the limiting cylinder 2 are coaxially rotatable. The photovoltaic panel 6 is detachably connected to the top surface of the mounting frame 5. The center of the bottom surface of the mounting frame 5 is obliquely connected to the column 4. A rotating component 3 is provided on the limiting cylinder 2. The mounting frame 5 and the rotating component 3 are connected by several diagonal braces 7. The mounting frame 5 is provided with an extension connection part 51.

[0031] In one or more embodiments, the base 1 can be a reinforced concrete component that is cast in place or prefabricated in a factory. The base 1 is used to provide stable support for the upper column 4 and the mounting frame 5, thereby ensuring the overall stability of the photovoltaic structure.

[0032] In optional implementations, such as Figure 1 As shown, the base 1 is provided with steps 11. The base 1 can be formed by casting in place or prefabricating in the factory, so that the base 1 has the feature of gradually increasing external size from top to bottom along the height direction. This can reduce the overall volume of the base 1 and lower the center of gravity of the base 1, thereby improving the stability of the base 1 in use. At the same time, when the base 1 is set on a slope, a working platform can be formed by laying wooden boards on the slope and steps 11, which makes it convenient for workers to stand on the working platform to install, maintain and repair the photovoltaic structure, thereby improving the efficiency of installation and maintenance.

[0033] In an optional embodiment, the base 1 may be provided with 1-3 steps 11.

[0034] In an optional embodiment, the limiting cylinder 2 can be partially embedded in the base 1 to improve the connection stability between the limiting cylinder 2 and the base 1.

[0035] In an optional embodiment, the limiting cylinder 2 can be composed of a pre-embedded section 21 and a connecting section 22. The pre-embedded section 21 is pre-embedded in the base 1 and a pre-embedded connector is provided through it. The pre-embedded section 21 and the connecting section 22 are detachably connected through the connector. The rotating component 3 can be set in the connecting section 22 and installed on the outside of the limiting cylinder 2. It can rotate around the axis of the column 4 by external force. The rotating component 3 can adopt the rotatable clamp structure in the existing single column 4 solar tracking rotating photovoltaic structure. The rotating component 3 is installed or welded with a connecting ear plate. By connecting the diagonal brace 7 to the connecting ear plate, the other end of the diagonal brace 7 is connected to the bottom surface of the mounting frame 5 to realize the supporting connection between the rotating component 3 and the mounting frame 5. By limiting the length of the diagonal brace 7, the tilt direction of the mounting frame 5 relative to the column is stabilized.

[0036] In an optional embodiment, one end of the diagonal brace 7 can be hinged to the rotating component 3 through a connecting lug and bolts, and the other end can be hinged to the outer edge of the mounting frame 5 through a connecting lug, so as to achieve stable support for the mounting frame 5 through multiple diagonal braces 7, thereby achieving stable support for the photovoltaic panel 6 above the mounting frame 5.

[0037] In one or more embodiments, the column 4 can be a hollow or cylindrical component with built-in reinforcing ribs. The column 4 extends into the limiting cylinder 2. The relative height between the column 4 and the limiting cylinder 2 can be set according to specific circumstances. The column 4 can rotate coaxially with the limiting cylinder 2.

[0038] In an optional embodiment, the outer wall of the limiting cylinder 2 can be provided with a drive control box, which is part of the existing single-column 4 solar-tracking rotating photovoltaic structure. The drive control box has a built-in drive mechanism that can receive signals from the associated solar position sensor and control the motor to run. A transmission mechanism such as gears or worm gears, which is part of the existing single-column 4 solar-tracking rotating photovoltaic structure, can be provided between the limiting cylinder 2 and the column 4. The drive mechanism drives the transmission mechanism to rotate and transmits power to the column 4, thereby achieving coaxial rotation control between the column 4 and the limiting cylinder 2.

[0039] In an optional embodiment, both the column 4 and the limiting cylinder 2 are cylindrical structural components.

[0040] In optional implementations, such as Figure 3 As shown, the top of the column 4 is provided with a first connecting plate 41, and the bottom of the mounting frame 5 is provided with a second connecting plate 55. The second connecting plate 55 and the first connecting plate 41 can be detachably connected by multiple bolts. The first connecting plate 41 and the second connecting plate 55 are aligned and connected to achieve quick assembly connection between the column 4 and the mounting frame 5. This allows both the column 4 and the mounting frame 5 to be prefabricated in the factory and then assembled on site, improving installation efficiency.

[0041] In one or more implementations, such as Figures 2-5As shown, the mounting frame 5 can be a frame structure composed of aluminum alloy or galvanized rods. The mounting frame 5 can match the rectangular features of the photovoltaic panel 6 to provide a stable support surface for multiple photovoltaic panels 6.

[0042] In optional implementations, such as Figure 2 As shown, the mounting frame 5 may include a support frame 52, which may be a square frame structure composed of aluminum alloy or galvanized rods. Multiple rods may be added to the inner side of the support frame 52 according to actual conditions to increase the support strength of the support frame 52 and realize the stable installation of the photovoltaic panel 6 on the support frame 52. A connection hole or an extension connection part 51 of the welding surface may be provided at the sloping top of the support frame 52.

[0043] In an optional embodiment, the extension connection 51 can be connected to the extension support frame 8 by bolts or welding. The extension support frame 8 and the support frame 52 are combined to support the photovoltaic panel 6 installed above, thereby expanding the support area of ​​the mounting frame 5.

[0044] In an optional embodiment, the extended support frame 8 can be a frame-shaped component made of aluminum alloy or galvanized rods. The extended support frame 8 can be connected to the extended connection part 51 on the support frame 52. The extended support frame 8 is provided with support purlins 81, so that the extended support frame 8 and the support frame 52 can support the photovoltaic panel 6 as a whole.

[0045] In optional implementations, such as Figure 2 , Figure 3 As shown, the mounting frame 5 includes several hollow rods 53, which penetrate the inclined top of the support frame 52. Support purlins 81 can be inserted into the hollow rods 53. Preferably, the hollow rods 53 are welded to the center of the area where the extension connection part 51 is located. When the extension support frame 8 is installed, the support purlins 81 distributed in the extension support frame 8 can be inserted into the hollow rods 53 to make the extension connection part 51 and the support frame 52 stably connected. Through the bolting or welding connection of the extension connection part 51, combined with the cooperation of the support purlins 81 and the hollow rods 53, the stable installation of the extension support frame 8 can be ensured.

[0046] In an optional embodiment, the circumferential sidewall of the support frame 52 is provided with a plurality of support arms 9, which can abut against the bottom surface of the photovoltaic panel 6. The support arms 9 can be rod segments cut from purlins. By abutting against the bottom surface of the photovoltaic panel 6, the support area of ​​the mounting frame 5 on the photovoltaic panel 6 can be increased, further ensuring the stable installation of the photovoltaic panel 6.

[0047] In an optional embodiment, the extended support frame 8 has several support arms 9 on its circumferential sidewalls to ensure the stable installation of the extended photovoltaic panels 6.

[0048] In an optional embodiment, a plurality of mounting purlins 10 are provided between the mounting frame 5 and the photovoltaic panel 6, and a plurality of limiting grooves 54 are provided on the top surface of the support frame 52. The mounting purlins 10 and the limiting grooves 54 are nested together. The mounting purlins 10 are typically located between adjacent photovoltaic panels 6 and are used to achieve stable positioning of the photovoltaic panel 6 and the mounting frame 5 through fasteners. By providing limiting grooves 54 on the top of the support frame 52, the mounting purlins 10 are installed stably and are not prone to positional movement relative to the support frame 52. This limiting effect further ensures the positional stability of the photovoltaic panel 6.

[0049] In optional implementations, such as Figure 2 As shown, a plurality of mounting holes 101 can be arranged on the mounting purlin 10. The mounting holes 101 can reduce the weight of the mounting purlin 10 and allow the fasteners to be adjusted in position according to the actual situation, which facilitates the fixing of the photovoltaic panel 6.

[0050] In optional implementations, such as Figure 2 , Figure 3 , Figure 5 As shown, the support arm 9 can be formed by extending the mounting purlin 10 in the length direction. The support arm 9 with short segment rods is only welded separately at local positions of the support frame 52 and the extension connecting frame 8, so as to reduce the process of setting the support arm 9 separately and achieve overall stable support for the photovoltaic panel 6.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
