[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] The terms "top," "bottom," "back," "side," and "axial" are used with reference to the normal operating state of the building-mounted photovoltaic module device and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] like Figures 1-3 As shown, the building photovoltaic module installation structure of this utility model includes a supporting substrate 2, a fixing component 3, and an angle limiting component 4. The supporting substrate 2 has a top edge 200 and a supporting surface 20 for supporting the photovoltaic module. The fixing component 3 is used to fix the relative position between the photovoltaic module and the supporting substrate 2. The angle limiting component 4 is used to limit the tilt position and vertical position of the supporting substrate 2. The top edge 200 is rotatably connected to the base 1 through a first rotating shaft 201 that extends in the same direction as the top edge 200. An extended baffle 23 is provided on the top of the supporting substrate 2. The extension direction of the extended baffle 23 is consistent with the orientation of the supporting surface 20 and is perpendicular to it or at an acute angle.

[0024] The supporting substrate 2 can switch between tilted and vertical positions through the angle limiting component 4, flexibly adjusting its tilt angle according to different angles of sunlight. It can also shrink the photovoltaic module to reduce the spread area to avoid damage from hail and increase the area of ​​the roof heating directly exposed to sunlight in winter, in response to severe weather such as hail and different seasons. Combined with the extended edge 23, it protects the photovoltaic modules installed on the supporting surface 20.

[0025] Preferably, the extension direction of the extended baffle 23 is perpendicular to the supporting surface 20. When the supporting substrate 2 is in an inclined position, the extended baffle 23 configured in this way blocks less incident sunlight and has better adaptability.

[0026] In one embodiment, the included angle limiting component 4 includes an arc-shaped guide 40, a slider 42, a screw 43, and a guide rod 41. The arc-shaped guide 40 is coaxially arranged with the first rotating shaft 201. The supporting substrate 2 has a bottom edge 202 that is opposite to the top edge 201 along its width direction. The two ends of the bottom edge 202 are sandwiched between the paired arc-shaped guides 40 and are slidably connected to them. The screw 43 and the guide rod 41 both extend in the direction toward the supporting substrate 2. The slider 42 is provided with a baffle 420 facing the back of the supporting substrate 2. The slider 42 reciprocates along the axial direction of the screw 43 and the guide rod 41, adjusting the baffle 420 to abut or separate from the back of the supporting substrate 2. One end of the screw 43 is connected to a motor 430. The slider 42 reciprocates along its axis through the screw 43 and the guide rod 41, thereby synchronously adjusting the support substrate 2 formed by multiple unit substrates coaxially to be in an inclined position or a vertical position. Combined with the arc-shaped guide 40, the tilt angle of the inclined position is determined and the support for the bottom edge 202 is improved.

[0027] To achieve the positioning of the tilted workstation, in one embodiment, the included angle limiting component 4 includes a gravity adjustment component 44, which is disposed at the bottom edge 202. By controlling the weight of the gravity adjustment component 44, the stability of the support substrate 2 in the tilted workstation is achieved, preventing the support substrate 2 from rotating and separating from the baffle 420 under the influence of harsh environments such as strong winds. The gravity adjustment component 44 is connected to the bottom edge 202 of the support substrate 2 through a second rotating shaft that is consistent with the axial direction of the first rotating shaft 201, ensuring that the gravity adjustment component 44 is in the plumb direction, that is, adjusting the gravity balance according to the tilt change of the support substrate 2.

[0028] In another embodiment, the included angle limiting component 4 includes an elastic element, one end of which is fixedly connected to the base 1 and the other end of which is fixedly connected to the supporting substrate 2. The elastic element has a natural contraction state when the supporting substrate 2 is in a vertical position and a tensile deformation state when it is in an inclined position; further, the elastic element is a spring. Figures 1-3 The elastic element is not shown, but it is positioned to avoid block 42, screw 43 and guide rod 41.

[0029] In a preferred embodiment, the included angle limiting component 4 includes a gravity adjustment component 44 and an elastic component, which improves the angle retention and stability of the supporting substrate in the tilted position under the gravity compensation and elastic reset mechanism.

[0030] For positioning of the vertically inclined workstation, the included angle limiting component 4 also includes a magnetic suction component 45, which is used to magnetically connect the support substrate 2 in the vertical workstation to the base 1.

[0031] In order to simplify the structure of the device and optimize the orderliness of the spatial arrangement, the axes of the screw 43 and the guide rod 41 are perpendicular to the support base plate 2 in the vertical position.

[0032] The supporting base plate 2 is provided with a front row of unit base plates 21 and at least one set of rear row of unit base plates 22 located on the back of the front row of unit base plates 21 at intervals along the axial direction of the screw 43. Each of the front row of unit base plates 21 and the rear row of unit base plates 22 is provided with an arc-shaped unit guide and a unit slider, and each unit slider is provided with a unit baffle. The unit sliders connected in series axially by the screw 43 act one-to-one on the front row of unit base plates 21 and the rear row of unit base plates 22, forming a multi-layer stacked structure. This enables synchronous and precise adjustment of the displacement of the unit baffles, thereby ensuring the consistency of the tilt position and the anti-displacement capability of the front row of unit base plates 21 and the rear row of unit base plates 22.

[0033] The screw 43 is divided into a first threaded section and a second threaded section, with the front unit substrate 21 as the dividing member. The second threaded section is located on the back side of the front unit substrate 21. The rear unit substrate 22, which is in a vertical position, divides the second threaded section axially into at least two equidistant reciprocating segments. The axial spacing of the reciprocating segments is greater than the extension length of the arc-shaped unit guide 40. With this arrangement, the unit baffle located on the side of the supporting surface of the rear unit substrate 22 can both adjust the tilt angle of the supporting substrate 2 in the tilted position and act as a baffle for the light-absorbing surface of the photovoltaic module, thus protecting the photovoltaic module. To achieve the above functions and effects, the extension height of the unit baffle is further located between the first rotating shaft 201 and the midline of the supporting substrate 2 in the vertical position, and the height from the top of the unit baffle to the base 1 is greater than the height from the extension end of the arc-shaped unit guide 40 to the base 1. Furthermore, the extension direction of the unit baffle is consistent with the extension direction of the supporting substrate 2 in the vertical position. After the unit baffle separates from the back of the supporting substrate 2, it reaches the light-incident surface of the rear unit substrate 22 in the vertical position.

[0034] To install photovoltaic modules of different widths and lengths, the fixing assembly 3 includes a bottom supporting edge 30, a top fixing edge 32, side fixing edges 31, and a fixing member 33. The bottom supporting edge 30 is fixedly connected to the bottom edge 202. The top fixing edge 32 is arranged opposite to the bottom supporting edge 30 along the width direction. Both the bottom supporting edge 30 and the top fixing edge 32 are provided with receiving grooves 300 between them and the supporting substrate 2. The end of the top fixing edge 32 is provided with a bent edge (not marked). The bent edge is bent along the side edge 203 of the supporting substrate 2 to the back of the supporting substrate 2 and is movable along the side edge 203. The side fixing edges 31 are arranged in pairs and are located on the side edge 203. The spacing between the pairs of side fixing edges 31 is adjustable. They are detachably fixedly connected to the bottom supporting edge 30, the top fixing edge 32, and the photovoltaic module by the fixing member 33. The fastener 33 includes, but is not limited to, a tightening screw, and the bottom supporting edge 30, the top fixing edge 32 and the side fixing edge 31 are all provided with threaded holes corresponding to the tightening screw.

[0035] To optimize the base structure and obtain a hollow and stable base 1, the base 1 is formed by connecting frame edges 11 and reinforcing rods 12. The length extension direction of the base 1 is consistent with the axial direction of the screw 43. The connecting frame edges 11 and reinforcing rods 12 are detachably fixed for easy transportation. The number of installation bases 1, the number of installation unit substrates, and the matching photovoltaic modules are determined according to the space of the building floor. The assembled building-mounted photovoltaic module device is fixedly connected to the building floor.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
