Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation, and in particular to a photovoltaic solar greenhouse with an adjustable roof angle. Background Technology

[0002] my country has precious land resources, and there are many benefits to building photovoltaic solar greenhouses on residential rooftops. It can not only reduce land occupation, but also increase the usable space of residents' houses.

[0003] Most existing photovoltaic greenhouses use welded beam-column systems. Welding is a specialized trade that requires professional welders, resulting in slow construction speed, high labor costs, high environmental requirements, and difficulty in guaranteeing weld quality. A small number of prefabricated greenhouses use frame systems, which have problems such as poor ability to cross obstacles, complex beam-column and purlin connection nodes, a large number of columns, and low prefabrication rate of components in factories.

[0004] Traditional photovoltaic greenhouses have fixed roof tilt angles, which cannot be adjusted according to local conditions during installation. The angle of the photovoltaic panels cannot approach the optimal tilt angle for the local area, making it difficult to guarantee power generation efficiency and meet usage requirements. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a practical and flexible photovoltaic solar greenhouse with an adjustable roof angle, which can adjust the roof angle to ensure optimal power generation efficiency.

[0006] This invention is achieved using the following scheme: a photovoltaic solar greenhouse with an adjustable roof angle, comprising support columns, a roof frame, and an inclined roof. The roof frame includes multiple sets of adjustable support frames spaced apart below the inclined roof. Each adjustable support frame includes multiple tripods arranged along the inclined direction of the roof. Each tripod is formed by a base rod, a vertical rod, and a diagonal rod, creating a right-angled triangle structure. The diagonal rods of all the tripods on the adjustable support frame form a supporting inclined beam that supports the inclined roof. Both the diagonal rods and the vertical rods of the tripods are telescopic structures, and the two ends of the diagonal rods are hinged to the base rod and the vertical rod, respectively, to achieve adjustment of the angle of the diagonal rods by extending and retracting the vertical rods.

[0007] Furthermore, the adjustable support frame also includes a telescopic frame located below the tripod for adjusting the height of the tripod. The height of the telescopic frames on the adjustable support frame increases progressively to form a stepped structure. The telescopic frame includes a horizontally arranged lower fixed rod and an upper movable rod. A pair of telescopic lifting arms are connected between the two ends of the lower fixed rod and the upper movable rod. The base of the tripod is bolted to the upper movable rod.

[0008] Furthermore, the lower fixed rod and the upper movable rod of the telescopic frame are connected by a first scissor bar and a second scissor bar that are cross-hinged. The upper end of the first scissor bar is hinged to the upper movable rod and the lower end is movably connected to the lower fixed rod. The lower end of the second scissor bar is hinged to the upper fixed rod and the upper end is movably connected to the upper movable rod.

[0009] Furthermore, the lifting arm is composed of multiple connecting rods that are sequentially connected. Adjacent connecting rods can slide relative to each other and are locked together by bolts. Each connecting rod has several bolt holes arranged along its length.

[0010] Furthermore, the diagonal bar of the tripod is composed of two segments that are sleeved together and can slide relative to each other; the vertical bar of the tripod is composed of at least two segments that are sleeved together in sequence, and the adjacent segments of the vertical bar can slide relative to each other and be locked and fixed by bolts, and each segment of the vertical bar has a number of bolt holes arranged along its length.

[0011] Furthermore, the inclined canopy is composed of an array of photovoltaic panels, and several purlins are erected on the upper side of the diagonal braces of the tripod and perpendicular to the diagonal braces. The photovoltaic panels are connected to the purlins.

[0012] Furthermore, the support column is composed of multiple lattice columns connected by bolts.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The photovoltaic sunshade with adjustable roof angle of the present invention is reasonably designed and highly practical. During installation, the roof angle and height can be adjusted according to the actual situation, making the layout flexible and adjusting the roof angle to the optimal tilt position as much as possible to ensure the best power generation efficiency of the photovoltaic panels.

Detailed Implementation

[0024] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] like Figures 1-8 As shown, a photovoltaic solar greenhouse with an adjustable roof angle includes support columns 100, a roof frame 200, and an inclined roof (not shown in the figure). The photovoltaic solar greenhouse can have an inclined roof with only a single inclination direction, or it can have two inclined roofs tilting towards different sides, so that the entire roof has a sloping structure that is higher in the middle and lower on both sides (e.g., Figure 2(As shown). The canopy frame 200 includes multiple sets of adjustable support frames 300 spaced apart below the inclined canopy surface. Each adjustable support frame 300 includes multiple tripods 310 arranged along the inclined direction of the inclined canopy surface. Each tripod is formed by a base rod 311, a vertical rod 312, and a diagonal rod 313 forming a right-angled triangle structure. The diagonal rods of all the tripods on the adjustable support frame form a supporting inclined beam 320 that supports the inclined canopy surface. The diagonal rods and vertical rods of the tripods are both telescopic structures, and the two ends of the diagonal rods are hinged to the base rod and the vertical rod, respectively, to achieve the connection of the vertical rods. The angle of the telescopic poles can be adjusted. Before installing the photovoltaic sunshade, the slope of the canopy is designed, and the length of the vertical pole of each tripod is adjusted to adjust the angle of the diagonal poles. The angle of the diagonal poles of each tripod in the adjustable support frame is the same, so that the slope of the support beam 320 is consistent with the designed slope of the canopy. The slope of the support beam 320 determines the slope of the canopy. This photovoltaic sunshade with adjustable canopy angle can be adjusted to the optimal tilt angle position according to local conditions to ensure the best power generation efficiency of the photovoltaic panels.

[0027] In this embodiment, to ensure that the diagonal bars of all tripods on the adjustable support frame remain aligned after the vertical bar length of the tripod is adjusted, the adjustable support frame 300 also includes a telescopic frame 330 located below the tripod for adjusting its height. The tripod height is adjusted via the telescopic frame below to ensure that the diagonal bars of each tripod remain aligned. However, the tripod at the lowest point does not require a telescopic frame for height adjustment. The telescopic frames on the adjustable support frame have progressively increasing heights, forming a stepped structure. The telescopic frame 330 includes a horizontally positioned lower fixed rod 331 and an upper movable rod 332. A pair of telescopic lifting arms 333 connect the two ends of the lower fixed rod and the upper movable rod. The base of the tripod is bolted to the upper movable rod. The height of the telescopic frame is adjusted by adjusting the length of the lifting arms, thereby adjusting the height of the tripod above it.

[0028] The entire canopy frame is assembled from two modules: a tripod and a telescopic frame. During manufacturing, only two sets of components, the tripod and the telescopic frame, need to be manufactured. These two sets of components can be processed and produced as similar standard parts. During installation, several tripods and telescopic frames can be used to assemble the canopy frame, which improves production and installation efficiency, reduces manufacturing costs, and accelerates production due to the high standardization of components.

[0029] In this embodiment, the lower fixed rods of two adjacent telescopic frames are connected together by a first connecting plate 340 on the side. The first connecting plate is connected to the lower fixed rod by bolts. The upper end of the vertical rod of the tripod is connected to the end of the upper movable rod of the next higher telescopic frame by a second connecting plate 350 on the side. The second connecting plate is connected to the vertical rod and the upper movable rod by bolts. The tripod and telescopic frame are connected by the first and second connecting plates to form an adjustable support frame with an integral structure, improving the overall stability of the adjustable support frame. When the photovoltaic sunshade is installed with the entire canopy being higher in the middle and lower on both sides, the adjustable support frames on both sides are installed symmetrically. The two tallest telescopic frames and tripods located in the middle of the horizontal direction are connected together by the first and second connecting plates, respectively. That is, the upper ends of the vertical rods of the two middle tripods are connected together by the second connecting plate, and the upper movable rods and lower fixed rods of the two middle tripods are connected together by the first connecting plate.

[0030] In this embodiment, the lower fixed rod and the upper movable rod of the telescopic frame 330 are also connected by a first scissor bar 334 and a second scissor bar 335 that are cross-hinged. The upper end of the first scissor bar is hinged to the upper movable rod and the lower end is movably connected to the lower fixed rod. The lower end of the second scissor bar is hinged to the upper fixed rod and the upper end is movably connected to the upper movable rod. The lower fixed rod is provided with a groove for movably connecting the lower end of the first scissor bar, and the upper movable rod is provided with a groove for movably connecting the upper end of the second scissor bar. The lower end of the first scissor bar and the upper end of the second scissor bar are both connected to rollers that cooperate with the corresponding grooves.

[0031] In this embodiment, the lifting arm is composed of multiple connecting rods that are sequentially connected. Adjacent connecting rods can slide relative to each other and are locked and fixed by bolts. Each connecting rod has several bolt holes arranged along its length. The length of the entire lifting arm can be adjusted by sliding the connecting rods. After adjustment, it is locked and fixed by bolts.

[0032] In this embodiment, the diagonal bar of the tripod is composed of two segments that are sleeved together and can slide relative to each other; the vertical bar of the tripod is composed of at least two segments that are sleeved together in sequence. The adjacent segments of the vertical bar can slide relative to each other and are locked and fixed by bolts. Each segment of the vertical bar has several bolt holes arranged along its length direction. The length of the entire vertical bar can be adjusted by sliding the segments. After adjustment, it is locked and fixed by bolts.

[0033] In this embodiment, the inclined canopy is composed of an array of photovoltaic panels. Several purlins 400 are installed on the upper side of the diagonal rods of the tripod and perpendicular to the diagonal rods. The photovoltaic panels are connected to the purlins, and the purlins and the diagonal rods of the tripod are also connected by bolts.

[0034] In this embodiment, the support column 100 is composed of multiple lattice columns connected by bolts. A support beam overlaps between the upper ends of two longitudinally adjacent support columns. The purlins are parallel to the support beams. The canopy frame is bolted to the top of the support beams. The columns are spliced ​​together from lattice columns as basic units, with uniform specifications and height, making production convenient. The addition of support beams reduces the number of columns and increases the span, improving the support columns' ability to cross obstacles and forming a large-span space.

[0035] In this embodiment, the photovoltaic panel assembly includes a frame and a photovoltaic panel embedded in the frame. The frame of the photovoltaic panel assembly is fixed to the purlin by a fixing buckle.

[0036] The canopy frame of this invention is assembled from two sets of components: a triangular frame and a telescopic frame. The components are highly standardized, which speeds up production efficiency and facilitates transportation. During installation, the angle and height of the canopy can be adjusted according to the actual situation, allowing for flexible layout and ensuring optimal power generation efficiency. No on-site welding is required, enabling rapid assembly and simplifying construction. The support columns are spliced ​​from basic units, ensuring uniform specifications and heights, facilitating production, improving the ability to overcome obstacles, and forming large-span spaces.

[0037] Unless otherwise stated, if any of the technical solutions disclosed in this invention specify a numerical range, then the disclosed numerical range is a preferred numerical range. Anyone skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this invention discloses only some numerical values ​​to illustrate the technical solutions of this invention. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this invention.

[0038] If this invention discloses or relates to mutually fixedly connected components or structural parts, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured in one piece using a casting process) (except where it is obviously impossible to use an integral molding process).

[0039] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this invention to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
