Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly to a retractable corrugated photovoltaic module support. Background Art

[0002] Photovoltaic power generation technology can bring green energy to human life and provide the convenience of portable and mobile energy supply, especially in areas where the power grid cannot reach, such as islands, aerial, wild mountains and other places. A container is a very common steel structure product, generally used for sea freight containers, land freight containers, cold chain transportation containers and dangerous product transportation containers, etc.

[0003] With the development of society and the rapid increase of population, containers have many innovative applications, such as: container houses, container shops, container hotels, container mobile power supplies, container water treatment tanks and container clinics, etc. The above-mentioned innovative applications are mainly based on three characteristics of the container: mobility, modularity and prefabrication.

[0004] With the progress of new energy technology and applications, the society has added a new element of photovoltaic power generation to the application of containers, thus giving birth to a container equipped with a photovoltaic power generation system, referred to as a photovoltaic container for short. The photovoltaic container generally adopts a design scheme of externally hanging a support and photovoltaic modules on the top surface of the container. However, due to the limited area of the top surface of the container, the installed photovoltaic capacity that can be implemented on the top surface generally cannot meet the energy requirements of actual applications. Therefore, engineering and technical personnel in this field have begun to consider how to use the space on the vertical wall of the container to install a photovoltaic power generation system to increase the overall installed capacity.

[0005] The design direction of installing a photovoltaic power generation system on the vertical wall of a container needs to face two problems: (1) For the photovoltaic modules facing the vertical direction, their power generation is generally only 30% - 70% of that of the photovoltaic modules facing the top surface; (2) Installing photovoltaic modules and supports on the vertical wall of the container will significantly increase the width of the container. If the original width of the container is not reduced, various problems will be brought about in logistics transportation, especially in terms of safety and violation of regulations; if the original width of the container is reduced, the available space inside the container will be sacrificed, seriously reducing the experience of using the container. For the first problem above, the solution in the prior art is to adopt a diagonal bracing support mechanism, using the vertical surface of the container as the foundation surface for the diagonal bracing support mechanism to support the photovoltaic modules and keep them in a horizontal state so as to achieve a more favorable orientation for higher power generation. However, due to the adoption of the diagonal bracing support mechanism, the width of the container will be further increased, that is, the second problem above will be magnified. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a retractable corrugated photovoltaic module bracket, which is convenient for retracting the retractable corrugated photovoltaic module bracket into the groove of the corrugated facade structure, thereby achieving a large compression of the photovoltaic module bracket in the thickness direction, and can be stretched out for use, thereby increasing the power generation of the photovoltaic module.

[0007] The technical solution of the present invention is:

[0008] A retractable corrugated photovoltaic component support, comprising a corrugated photovoltaic component bracket, a plurality of bracket flip connection mechanisms and a plurality of groups of retractable diagonal brace components, wherein the plurality of bracket flip connection mechanisms are connected to one side of the corrugated photovoltaic component bracket, each bracket flip connection mechanism comprises a fixed hinge seat, a rotating connection plate and a horizontal rotation axis, the rotating connection plates of the plurality of bracket flip connection mechanisms are parallel to each other and are fixed to one side of the corrugated photovoltaic component bracket, the fixed hinge seat is located to the side of one side of the corrugated photovoltaic component bracket, one end of the rotating connection plate is hinged to the corresponding fixed hinge seat through the horizontal rotation axis, and the axial extension lines of the horizontal rotation axes of the plurality of bracket flip connection mechanisms overlap each other and are parallel to one side of the corrugated photovoltaic component bracket connected to the rotating connection plate;

[0009] Each group of retractable diagonal brace assemblies is installed corresponding to a bracket flip connection mechanism, and each group of retractable diagonal brace assemblies includes a vertically arranged supporting beam, and a first diagonal brace, a second diagonal brace and a third diagonal brace. Each supporting beam is located directly below a corresponding fixed hinged seat of the bracket flip connection mechanism. A vertical guide rail is arranged on each supporting beam, and a slider is slidably connected in the vertical guide rail. The top end of the first diagonal brace is hinged to the corrugated photovoltaic component bracket and is adjacent to the corresponding bracket flip connection mechanism. The bottom end of the first diagonal brace is hinged to the second diagonal brace, and the bottom end of the second diagonal brace is hinged to the slider. The top end of the second diagonal brace is hinged to the bottom end of the third diagonal brace, and the top end of the third diagonal brace is hinged to the corrugated photovoltaic component bracket. When the corrugated photovoltaic component bracket is in a horizontally opened state, the angle between the second diagonal brace and the third diagonal brace is 180 degrees.

[0010] The corrugated photovoltaic component bracket includes a plurality of mutually parallel corrugated cross beams and a plurality of mutually parallel concave longitudinal beams. The plurality of corrugated cross beams and the plurality of concave longitudinal beams are perpendicular to each other to form a cross grid structure. Each concave longitudinal beam is tightly connected to the concave top surface of the plurality of corrugated cross beams overlapping in the longitudinal direction. The inner ends of the plurality of concave longitudinal beams are connected to corresponding bracket flip connection mechanisms. The top end of the first diagonal brace of each group of retractable diagonal brace assemblies is hinged to the inner end of a corresponding concave longitudinal beam, and the top end of the third diagonal brace of each group of retractable diagonal brace assemblies is hinged to the middle part of a corresponding concave longitudinal beam.

[0011] When the corrugated photovoltaic module bracket is in a horizontally opened state, an overlapping part is formed between the second diagonal brace and the third diagonal brace. Positioning holes are provided on the overlapping parts of the second diagonal brace and the third diagonal brace, and the positioning holes of the second diagonal brace and the third diagonal brace overlap with each other. A positioning pin passes through the overlapping positioning holes to lock and fix the second diagonal brace and the third diagonal brace.

[0012] The first diagonal brace, the second diagonal brace, and the third diagonal brace are all U-shaped groove steel structures. The bottom end of the first diagonal brace is hinged to the middle part of the second diagonal brace. When the corrugated photovoltaic module bracket rotates to a vertical state, the upper half of the second diagonal brace rotates into the U-shaped groove of the first diagonal brace, and a part of the third diagonal brace rotates into the U-shaped groove of the second diagonal brace.

[0013] Long strip-shaped through holes are provided at the bottom of the grooves between the inner end and the middle part, and between the middle part and the outer end of each concave longitudinal beam. The total length of the first diagonal brace, the second diagonal brace, and the third diagonal brace after folding is less than the length of the long strip-shaped through hole between the inner end and the middle part of the concave longitudinal beam. An end hinged seat is fixed on the top surface of the groove bottom at the inner end of the concave longitudinal beam, and a middle hinged seat is fixed on the top surface of the groove bottom in the middle of the concave longitudinal beam. The top end of the first diagonal brace passes through the long strip-shaped through hole between the inner end and the middle part of the concave longitudinal beam and is hinged to the end hinged seat, and the top end of the third diagonal brace passes through the long strip-shaped through hole between the inner end and the middle part of the concave longitudinal beam and is hinged to the middle hinged seat.

[0014] Long strip-shaped photovoltaic module support substrates are provided at both top ends of the concave longitudinal beam, and the photovoltaic modules are supported and fixed on the photovoltaic module support substrates of multiple concave longitudinal beams.

[0015] Collision prevention bars are fixedly connected to the outer ends of the multiple concave longitudinal beams, and a part of the collision prevention bars extends to the outside of the concave longitudinal beam.

[0016] Advantages of the present invention:

[0017] (1) The bracket for supporting and fixing the photovoltaic module in the present invention is a corrugated structure. When the photovoltaic module shrinks to the vertical surface, the corrugated photovoltaic module bracket can shrink into the corrugated groove of the container, obtaining a photovoltaic container whose width meets the width standard of the sea freight container or the land freight container, without sacrificing the original available space in the container.

[0018] (2) Long strip-shaped through holes are provided on the corrugated photovoltaic module bracket of the present invention. When the photovoltaic module shrinks to the vertical surface, the three diagonal braces of each set of retractable diagonal brace assemblies can be folded and passed through the long strip-shaped through hole between the inner end and the middle part of the concave longitudinal beam and placed in the groove of the concave longitudinal beam, further reducing the thickness of the photovoltaic module after shrinking and folding. At the same time, the two long strip-shaped through holes provided on each concave longitudinal beam further reduce the weight of the photovoltaic module bracket, facilitating logistics transportation.

[0019] (3) A photovoltaic module support substrate is provided on the concave longitudinal beam of the present invention for supporting and fixing the photovoltaic module, which increases the contact area between the photovoltaic module support and the photovoltaic module and improves the stability of the support connection of the photovoltaic module.

[0020] (4) A bumper bar is provided at the outer end of the concave longitudinal beam of the present invention. When the corrugated photovoltaic module bracket rotates to the vertical surface, it prevents the corrugated photovoltaic module bracket and the photovoltaic module on the bracket from colliding with the ground and being damaged.

[0021] (5) The first diagonal brace, the second diagonal brace, and the third diagonal brace of the present invention are all U-shaped groove steel structures, which realize the nested folding of the three diagonal braces, further reducing the thickness of the photovoltaic module support after folding. Moreover, the total length of the first diagonal brace, the second diagonal brace, and the third diagonal brace after folding is less than the length of the long strip through hole between the inner end and the middle of the concave longitudinal beam, avoiding the problem of deformation caused by the three diagonal braces rotating and folding to the vertical state and extending outside the long strip through hole between the inner end and the middle of the concave longitudinal beam.

The upper half of the second diagonal support 33 rotates into the U-shaped groove of the first diagonal support 32, and a part of the third diagonal support 34 rotates into the U-shaped groove of the second diagonal support 33. The three diagonal supports are nested and folded, and the folded three diagonal supports pass through the long strip through hole 13 between the inner end and the middle of the concave longitudinal beam 12 and are supported in the groove plate surface on the facade corrugated board 6. At the same time, the corrugated photovoltaic module bracket is also placed on the facade corrugated board 6, and the two are nested and overlapped, and the photovoltaic module 5 is closely attached to the facade corrugated board 6.
