Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation technology, and more specifically, to an assembled photovoltaic structure and an assembled building roof. Background Art

[0002] With the development of science and technology, more and more energy is used. As the old oil and coal resources are exhausted, people are more and more inclined to develop new energy sources, such as solar energy. Photovoltaic modules, also called solar panels or photovoltaic panels, are the core components for realizing photoelectric conversion in photovoltaic power generation systems. Their function is to convert the radiation energy of sunlight into direct current electricity.

[0003] With the increase in electricity demand in every household, photovoltaic modules can also be installed on the roofs of buildings in plain areas and other areas with sufficient light resources, and photovoltaic panels can be used to generate electricity for indoor use to achieve the goal of energy conservation and emission reduction; for example, Chinese patent invention patent CN108729598A discloses a photovoltaic roof system, including photovoltaic module panels, a load-bearing support is provided under the photovoltaic module panels, a guide rail is fixed on the load-bearing support, and a front support and a rear support are respectively clamped at the front and rear ends of the guide rail, and the photovoltaic module panels are erected on the front support and the rear support with an inclined surface with a low front and a high rear; the photovoltaic module panels are surrounded by panels extending from the bottom of the load-bearing support to the roof, and the panels, photovoltaic module panels and the roof form a closed structure roof system; the photovoltaic roof system also includes an electrical system. The bottom support of the above invention is made of concrete, which increases the height of the photovoltaic system from the roof, avoids water corrosion in the system, and provides wind load resistance; the surrounding panels extend from the bottom of the concrete support to the roof, completely covering the photovoltaic system, giving the photovoltaic system a diversion and exhaust effect; the overall structure of the photovoltaic module panels is modularized and easy to install. However, the above photovoltaic roof system still has the following disadvantages: photovoltaic modules are all arranged on the inclined roof. After the photovoltaic modules are installed, the roof cannot assist in lighting and ventilation. When it rains, rainwater can only flow over the photovoltaic panels. After a long time, dirt will form and affect the efficiency of photovoltaic power generation. There is also a lack of waterproof and water-conducting capabilities, and the service life of photovoltaic modules is short.

[0004] In summary, the roof photovoltaic structure in the prior art has technical problems such as obstruction of roof lighting and ventilation, lack of waterproof and water-conducting capabilities, and short service life. Utility Model Content

[0032] In view of the shortcomings of the existing methods, this application proposes an assembled photovoltaic structure and an assembled building roof to solve the technical problems existing in the prior art, such as obstruction of roof lighting and ventilation, lack of waterproof and water-conducting capabilities, and short service life.

[0033] In a first aspect, the present application provides an assembled photovoltaic structure, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an assembled photovoltaic structure in an embodiment of the present application.

[0034] The assembled photovoltaic structure comprises a plurality of photovoltaic units, wherein the plurality of photovoltaic units are distributed in a stepped manner, and each of the photovoltaic units comprises:

[0035] The photovoltaic part 1 comprises a substrate 11 and a photovoltaic panel 12. The photovoltaic panel 12 is covered on the substrate 11. A drainage groove 111 is provided on the surface of the substrate 11.

[0036] A bottom plate 2, supporting the substrate 11;

[0037] A lifting column 21, connecting the photovoltaic part 1 and the bottom plate 2;

[0038] The connecting plate 3 is connected to one end of the bottom plate 2 , and the connecting plate 3 has a functional window 31 .

[0039] In the embodiment of the present application, multiple photovoltaic units are distributed in a stepped manner and assembled in conjunction with the roof panel, which is convenient to install and has good stability. The lifting column 21 is used to change the angle between the photovoltaic part 1 and the base plate 2. In fine weather, the photovoltaic panel 12 can be set parallel to the base plate 2, and the functional window 31 is used for lighting and ventilation. In rainy and snowy weather, the photovoltaic panel 12 is tilted relative to the base plate 2 to guide rainwater to flow down, and the rainwater flows down from the drainage groove 111 under the photovoltaic panel 12. The drainage capacity is strong, will not affect the power generation efficiency of the photovoltaic panel 12, and the photovoltaic component has a long service life.

[0040] In this embodiment, the roof is set to a stepped structure. In multiple photovoltaic units, multiple horizontally arranged bottom plates 2 are alternately connected with multiple vertically arranged connecting plates 3. A connecting plate 3 is arranged between any two adjacent bottom plates 2, and a bottom plate 2 is arranged between any two adjacent connecting plates 3. The bottom plates 2 are connected end to end with adjacent connecting plates 3, and the connecting plates 3 are connected end to end with adjacent bottom plates 2. One or more photovoltaic parts 1 can be set on each bottom plate 2; the number of bottom plates 2 and photovoltaic panels 12 can be assembled and installed according to the size of the roof, and the installation is convenient and stable.

[0041] It is worth mentioning that in the above embodiment, the bottom plate 2 is horizontal and the connecting plate 3 is vertical. In fact, the bottom plate 2 can form an angle of no more than 15 degrees with the horizontal plane, and the connecting plate 3 can form an angle of no more than 15 degrees with the vertical plane.

[0042] like Figure 2 As shown, Figure 2 This is a side view of a photovoltaic part in an embodiment of the present application.

[0043] In some embodiments of the present application, the photovoltaic panel 12 includes a first sub-panel 121 and a second sub-panel 122 . A through hole 123 exists between the first sub-panel 121 and the second sub-panel 122 . The through hole 123 is connected to the drainage groove 111 .

[0044] In some embodiments of the present application, a stop valve 124 is further included. The stop valve 124 is located in the through hole 123 and the opening and closing member of the stop valve 124 is oriented parallel to the axial direction of the through hole 123 .

[0045] like Figure 3 As shown, Figure 3 This is a top view of an assembled photovoltaic structure in an embodiment of the present application.

[0046] In some embodiments of the present application, the through hole 123 includes a continuous strip hole or a plurality of spaced cylindrical holes, the drainage grooves 111 correspond one-to-one to the through hole 123, and the number of the drainage grooves 111 is one or more.

[0047] In this embodiment, the photovoltaic part 1 includes a substrate 11 and a photovoltaic panel 12 arranged on the substrate 11. The area of ​​the substrate 11 is not less than the area of ​​the photovoltaic panel 12. The lifting column 21 and the hinge block 23 can be installed under the substrate 11 without affecting the performance of the photovoltaic panel 12; and a drainage groove 111 is arranged on the substrate 11. In fact, the drainage groove 111 is between the substrate 11 and the photovoltaic panel 12, so that rainwater is guided to flow down from the bottom of the photovoltaic panel 12. The drainage capacity is strong, the power generation efficiency of the photovoltaic panel will not be affected, and the service life of the photovoltaic module is long.

[0048] The photovoltaic panel 12 includes a first sub-panel 121 and a second sub-panel 122 disposed on a side of the first sub-panel 121 close to the hinge block 23, and a through hole 123 for communicating with the drainage groove 111 is disposed between the first sub-panel 121 and the second sub-panel 122. Then, rainwater on the higher photovoltaic part 1 will still reach the upper part of the lower photovoltaic part 1 after flowing down, and after reaching the first sub-panel 121, the rainwater can flow from the through hole 123 between the first sub-panel 121 and the second sub-panel 122 to the drainage groove 111 on the lower side of the second sub-panel 122, thereby reducing the rainwater coverage area of ​​the photovoltaic panel.

[0049] The number of the through hole 123 is at least one, and the number of the drainage groove 111 is at least one. A stop valve 124 is provided at the through hole 123; under normal circumstances, the stop valve 124 is open, and rainwater can flow down from the through hole 123; but when the photovoltaic panel 12 needs to be cleaned at intervals, the stop valve 124 is closed, and the cleaning water flows on the photovoltaic panel 12 to clean the photovoltaic panel 12.

[0050] In some embodiments of the present application, a hinge block 23 is further included. The hinge block 23 is located at one end of the bottom plate 2 away from the connecting plate 3 and connects the bottom plate 2 and the base plate 11 .

[0051] In some embodiments of the present application, a hinge rod 22 is further included, a mounting groove is opened on the surface of the base plate 2, the mounting groove is located between the connecting plate 3 and the hinge block 23, one end of the lifting column 21 is embedded in the mounting groove, and the hinge rod 22 is located at one end of the lifting column 21 away from the base plate 2 and connects the lifting column 21 and the base plate 11.

[0052] In this embodiment, the photovoltaic part 1 is a generally planar plate-like structure, and a lifting column 21 for supporting the photovoltaic part 1 is provided on the base plate 2. The lifting column 21 can drive the photovoltaic part 1 to flip and change the angle formed between the photovoltaic part 1 and the base plate 2; that is, when the lifting column 21 is raised, the angle between the photovoltaic part 1 and the base plate 2 becomes larger; conversely, when the lifting column 21 is lowered, the angle between the photovoltaic part 1 and the base plate 2 becomes smaller (tends to be parallel).

[0053] The lifting column 21 is located between the two ends of the bottom plate 2, and the lifting column 21 is more inclined to one end of the connecting plate 3. The end of the bottom plate 2 away from the lifting column 21 is provided with a hinge block 23 for connecting with the base plate 11. When the lifting column 21 is raised or lowered, the photovoltaic part 1 rotates around the connection with the hinge block 23; moreover, a functional window 31 is provided on the connecting plate 3; when the lifting column 21 is lowered, the functional window 31 will not be blocked by the photovoltaic part 1, and the functional window 31 is a transparent part, so lighting can be provided at this time, and even ventilation can be provided if the functional window 31 is opened; when the lifting column 21 is raised, the photovoltaic part 1 blocks the functional window 31, and the inclination angle of the photovoltaic part 1 becomes larger, which can facilitate solar energy collection and guide rainwater to flow down when it rains.

[0054] In fine weather, the lifting column 21 can be raised to tilt the photovoltaic part 1 for lighting and power generation, and the lifting column 21 can also be lowered when necessary for lighting and ventilation through the functional window 31; in rainy and snowy weather, the lifting column 21 needs to be raised to tilt the photovoltaic part 1 to guide rainwater to flow down, so as to avoid dirt accumulation on the surface of the photovoltaic part 1.

[0055] The upper end of the lifting column 21 is connected to the base plate 11 through the hinge rod 22, so that the rotation of the photovoltaic part 1 is more stable and smooth. In fact, a limit spring of the hinge rod 22 is arranged on the upper end of the lifting column 21, so that the hinge rod 22 is generally extended upward.

[0056] The base plate 2 is provided with an installation groove for facilitating the installation of the lifting column 21, so that when the lifting column 21 is lowered, the photovoltaic part 1 can be as parallel to the base plate 2 as possible; a driving machine for driving the lifting column 21 to extend and retract is also arranged in the installation.

[0057] like Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of another assembled photovoltaic structure in an embodiment of the present application.

[0058] In some embodiments of the present application, there is a height difference between any two adjacent photovoltaic units, and the height difference is equal to the height of the connecting plate 3 .

[0060] In this embodiment, the heights of two adjacent base plates 2 are different; generally speaking, the heights of the multiple base plates 2 decrease from the center of the roof to the edge, and the connecting plate 3 is vertically arranged; so that the first connecting plate at one end of the first base plate is located at the end of the first base plate facing upward, and correspondingly, the first connecting plate is located at the end of the second base plate facing downward; that is, of the two adjacent base plates, the end of the second base plate with a higher position facing downward is connected to the end of the first base plate with a lower position facing upward through the first connecting plate.

[0061] In some embodiments of the present application, the angle between the bottom plate 2 and the horizontal plane is not less than 0 degrees and not more than 15 degrees.
