DETAILED DESCRIPTION

[0015] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0016] Photovoltaic power generation is a technology that converts light energy into electricity by using the photovoltaic effect of the semiconductor interface. Since solar energy is inexhaustible and renewable, and it is clean and safe, it has attracted more and more attention.

[0017] The photovoltaic device in the related art includes a support and a photovoltaic panel. The photovoltaic panel is installed on the support. Light is incident on the light-receiving surface of the photovoltaic panel and is converted into electrical energy by the photovoltaic panel. However, the photovoltaic device in the related art has a structure of the support, which limits the light-receiving surface of the photovoltaic panel from facing the sun for a long time, so that the photovoltaic panel receives light for a short time, resulting in low power generation efficiency of the photovoltaic device. Therefore, how to improve the support of the photovoltaic device to improve the power generation efficiency of the photovoltaic device has become a problem to be solved.

[0018] To solve the above problems, please refer to Figures 1-2 The present application proposes a photovoltaic device 1 that can effectively improve the power generation efficiency.

[0019] The photovoltaic device 1 comprises a plurality of photovoltaic modules 10 arranged along a first direction MM'; each photovoltaic module 10 comprises a vertical beam group 11, a cross beam assembly 12 and a photovoltaic panel 13. The number of vertical beam groups 11 is two, and the two vertical beam groups 11 are oppositely arranged along a second direction NN'; each vertical beam group 11 comprises two vertical beam assemblies 111; the vertical beam assemblies 111 can move up and down along a vertical direction; the second direction NN' intersects the first direction MM'. One side of the cross beam assembly 12 is connected to the top ends of the two vertical beam assemblies 111 in one vertical beam group 11, and the other side of the cross beam assembly 12 is connected to the top ends of the two vertical beam assemblies 111 in the other vertical beam group 11. The photovoltaic panel 13 is arranged on the cross beam assembly 12. The two vertical beam assemblies 111 in one vertical beam group 11 and the two vertical beam assemblies 111 in the other vertical beam group 11 are arranged in one-to-one correspondence to form two adjustment groups; the adjustment groups are configured to change the angle of the photovoltaic panel 13 by adjusting the height of the vertical beam assembly 111.

[0020] The specific structure of the photovoltaic device 1 will be introduced in detail below. Figures 1-6 The specific structure of the photovoltaic device 1 will be introduced in detail below.

[0021] As shown in Figures 1-2 , the photovoltaic device 1 comprises a plurality of photovoltaic modules 10 arranged along a first direction MM'; at this time, the plurality of photovoltaic modules 10 are spliced with each other to form a sunshade area, and users can perform outdoor activities such as camping and playing football in the sunshade area.

[0022] Each photovoltaic module 10 comprises a vertical beam group 11, a cross beam assembly 12 and a photovoltaic panel 13.

[0023] The vertical beam group 11 serves as a longitudinal support of the photovoltaic module 10 and is used to support the cross beam assembly 12.

[0024] The number of vertical beam groups 11 is two, and the two vertical beam groups 11 are oppositely arranged along a second direction NN'; wherein, the second direction NN' intersects the first direction MM' (that is, the second direction NN' at least comprises a component perpendicular to the first direction MM').

[0025] Each vertical beam group 11 comprises two vertical beam assemblies 111; the vertical beam assemblies 111 can move up and down along a vertical direction. The specific structure of the vertical beam assembly 111 will be introduced in detail below.

[0026] The cross beam assembly 12 serves as a transverse support of the photovoltaic module 10 and is used to carry the photovoltaic panel 13; the specific structure of the cross beam assembly 12 will be introduced in detail below.

[0027] One side of the cross beam assembly 12 is connected to the top ends of the two vertical beam assemblies 111 in one vertical beam group 11, and the other side of the cross beam assembly 12 is connected to the top ends of the two vertical beam assemblies 111 in the other vertical beam group 11.

[0028] The photovoltaic panel 13 is used as an energy conversion structure of the photovoltaic module 10 to convert solar energy into electric energy. The specific structure of the photovoltaic panel 13 is not limited here, and the designer can reasonably design according to actual needs; for example, the photovoltaic panel 13 includes a panel, a cell layer, and a back plate arranged in sequence.

[0029] The photovoltaic panel 13 is arranged on the cross beam assembly 12. The specific connection mode between the photovoltaic panel 13 and the cross beam assembly 12 is not limited here, and the designer can reasonably design according to actual needs; for example, the photovoltaic panel 13 can be, but is not limited to, detachably connected with the cross beam assembly 12 by at least one of screwing, clamping, or inserting.

[0030] The number of photovoltaic panels 13 can be one or more (two or more). For example, when the number of photovoltaic panels 13 is one, the one photovoltaic panel 13 is a long strip-shaped photovoltaic panel 13 extending along the second direction NN'; the long strip-shaped photovoltaic panel 13 projects on the ground to form a continuous long strip-shaped sun-shading area, and the projections of the photovoltaic panels 13 in the plurality of photovoltaic modules 10 on the ground can be spliced to form a larger sun-shading area. For another example, when the number of photovoltaic panels 13 is more, each photovoltaic panel 13 can be a square photovoltaic panel 13; the plurality of square photovoltaic panels 13 are arranged along the second direction NN' and project on the ground to form an intermittent long strip-shaped sun-shading area, and the projections of the photovoltaic panels 13 in the plurality of photovoltaic modules 10 on the ground can be spliced to form a larger sun-shading area. It should be noted that the number of photovoltaic panels 13 included in the photovoltaic module 10 can be the same or different for different photovoltaic modules 10, and the designer can reasonably design according to actual needs.

[0031] Two cross beam assemblies 111 in one cross beam group 11 are arranged in one-to-one correspondence with two cross beam assemblies 111 in another cross beam group 11 to form two adjustment groups; the adjustment groups are configured to change the angle of the photovoltaic panel 13 by adjusting the height of the cross beam assembly 111. For example, the height of the two cross beam assemblies 111 in one adjustment group can be changed by making the two cross beam assemblies 111 do lifting movement, thereby changing the angle of the photovoltaic panel 13, so that the light-receiving surface of the photovoltaic panel 13 can face the sun, to improve the power generation efficiency of the photovoltaic device 1; the height of the four cross beam assemblies 111 in the two adjustment groups can also be changed by making the four cross beam assemblies 111 do lifting movement, thereby changing the angle of the photovoltaic panel 13, so that the light-receiving surface of the photovoltaic panel 13 can face the sun, to improve the power generation efficiency of the photovoltaic device 1.

[0032] Based on the photovoltaic device 1 in the embodiment of the present application, by designing the vertical beam group 11 and the cross beam assembly 12, the vertical beam group 11 and the cross beam assembly 12 constitute the support of the photovoltaic module 10 for providing support for the photovoltaic panel 13. By designing the photovoltaic panel 13, the photovoltaic panel 13 can convert solar energy into electrical energy to achieve effective utilization of solar energy. By designing the vertical beam assembly 111 which can move up and down in the vertical direction, the height of the two vertical beam assemblies 111 in one adjusting group can be changed by making the two vertical beam assemblies 111 in the adjusting group move up and down, so as to change the angle of the photovoltaic panel 13, so that the light receiving surface of the photovoltaic panel 13 can face the sun, so as to improve the power generation efficiency of the photovoltaic device 1; the height of the four vertical beam assemblies 111 in two adjusting groups can also be changed by making the four vertical beam assemblies 111 in the two adjusting groups move up and down, so as to change the angle of the photovoltaic panel 13, so that the light receiving surface of the photovoltaic panel 13 can face the sun, so as to improve the power generation efficiency of the photovoltaic device 1. The plurality of photovoltaic modules 10 are arranged along the first direction MM', and the projections of the photovoltaic panels 13 in the plurality of photovoltaic modules 10 on the ground can be spliced to form a larger sun-shading area, and the user can perform outdoor activities such as camping and playing football in the sun-shading area.

[0033] As shown in Figures 3-4 The cross beam assembly 12 includes a telescopic cross beam 121 and an elastic support body 122. The number of the telescopic cross beams 121 is two, one end of one telescopic cross beam 121 is rotatably connected with the top end of the two vertical beam assemblies 111 in one vertical beam group 11, and the other end of the telescopic cross beam 121 is rotatably connected with the top end of the two vertical beam assemblies 111 in the other vertical beam group 11. The elastic support body 122 is connected between the two telescopic cross beams 121, and the photovoltaic panel 13 is arranged on the elastic support body 122. By designing the two telescopic cross beams 121, one telescopic cross beam 121 and the two vertical beam assemblies 111 in one vertical beam group 11 connected with the telescopic cross beam 121 constitute one single-side support of the photovoltaic module 10, and the other telescopic cross beam 121 and the two vertical beam assemblies 111 in the other vertical beam group 11 connected with the telescopic cross beam 121 constitute the other single-side support of the photovoltaic module 10, and in the process of the vertical beam assembly 111 of the adjusting group moving up and down, the telescopic cross beam 121 can move up and down to adapt to the height adjustment of the vertical beam assembly 111; by designing the elastic support body 122, the elastic support body 122 can provide good support for the photovoltaic panel 13. It should be noted that the elastic support body 122 can deform under external force and has good support effect; the height adjustment realized by the vertical beam assembly 111 of the adjusting group moving up and down is small amplitude adjustment, and the elastic deformation of the elastic support body 122 in the process of the vertical beam assembly 111 of the adjusting group moving up and down can adapt to the small amplitude adjustment, that is, the elastic support body 122 will not fail such as breaking.

[0034] As shown in Figure 2As shown, the number of photovoltaic panels 13 is multiple, and the multiple photovoltaic panels 13 are arranged on the elastic support body 122 in sequence along the second direction NN'. The projection of the multiple photovoltaic panels 13 on the ground forms an interrupted long strip-shaped sun-shading area, and the projection of the photovoltaic panels 13 in the multiple photovoltaic modules 10 on the ground can be spliced to form a larger sun-shading area.

[0035] As shown, Figures 3-4 The telescopic cross beam 121 includes a first cross beam 1211 and a second cross beam 1212. The connecting end of the first cross beam 1211 is rotatably connected to the top end of one of the vertical beam assemblies 111 of the corresponding vertical beam group 11; the second cross beam 1212 is sleeved on the first cross beam 1211 and can make relative telescopic movement with the first cross beam 1211, and the connecting end of the second cross beam 1212 is rotatably connected to the top end of another vertical beam assembly 111 of the corresponding vertical beam group 11. The elastic support body 122 is connected to the second cross beam 1212.

[0036] The connecting end of the first cross beam 1211 can be but is not limited to connected to the top end of one of the vertical beam assemblies 111 of the corresponding vertical beam group 11 through a rotating shaft; the connecting end of the second cross beam 1212 can be but is not limited to connected to the top end of another vertical beam assembly 111 of the corresponding vertical beam group 11 through a rotating shaft. The second cross beam 1212 and the first cross beam 1211 are sleeved to form a telescopic rod structure.

[0037] By designing the first cross beam 1211 and the second cross beam 1212, during the lifting movement of the vertical beam assembly 111 of the adjusting group, the first cross beam 1211 and the second cross beam 1212 can make relative telescopic movement to adapt to the height adjustment of the vertical beam assembly 111.

[0038] As shown, Figure 2 and Figure 4 The elastic support body 122 includes a spring steel wire 1221; the end of the spring steel wire 1221 is wound around the second cross beam 1212; and the photovoltaic panel 13 is fixed to the spring steel wire 1221. The spring steel wire 1221 can be but is not limited to a carbon spring steel wire 1221 or an alloy spring steel wire 1221, etc. The specific connection mode between the photovoltaic panel 13 and the spring steel wire 1221 is not limited here, and the designer can reasonably design according to actual needs; for example, the photovoltaic panel 13 can be connected to the spring steel wire 1221 through a hoop type lock or a strap, etc. to fix the photovoltaic panel 13 to the spring steel wire 1221. By designing the elastic support body 122 as a spring steel wire 1221, it has high tensile strength, elastic limit, toughness, fatigue strength, and is resistant to impact and vibration, so as to provide good support for the photovoltaic panel 13. It should be noted that the number of spring steel wires 1221 is multiple, and the multiple spring steel wires 1221 are arranged at intervals to provide stable support for the photovoltaic panel 13.

[0039] AsFigure 4 As shown, the outer surface of the second cross beam 1212 is provided with a groove, and the end of the spring wire 1221 is wound around the second cross beam 1212 and embedded in the groove. By designing the groove on the outer surface of the second cross beam 1212 and embedding the spring wire 1221 in the groove, the groove wall limits the spring wire 1221, thereby enhancing the connection stability between the spring wire 1221 and the second cross beam 1212 and the installation stability of the photovoltaic panel 13.

[0040] As shown in FIG. 1, Figure 2 As shown in FIG. 1, the photovoltaic module 10 further comprises two inclined beam groups 14 corresponding to the two vertical beam groups 11; the two inclined beam groups 14 are oppositely arranged along the second direction NN', and each inclined beam group 14 comprises two telescopic inclined beam assemblies 141, and the two inclined beam assemblies 141 in the inclined beam group 14 are connected to the top ends of the two vertical beam assemblies 111 in the corresponding vertical beam group 11. By designing the two inclined beam groups 14, the two inclined beam assemblies 141 in each inclined beam group 14 are connected to the top ends of the two vertical beam assemblies 111 in the corresponding vertical beam group 11, and the inclined beam assembly 141 provides support for the vertical beam assembly 111 to assist the vertical beam assembly 111 in providing support for the cross beam assembly 12, thereby enhancing the structural stability of the photovoltaic module 10 as a whole.

[0041] As shown in FIG. 1, Figure 2 As shown in FIG. 1, each inclined beam assembly 141 comprises a telescopic inclined beam 1411; one end of the telescopic inclined beam 1411 is connected to the top end of the corresponding vertical beam assembly 111, and the other end of the telescopic inclined beam 1411 is used to be connected to the ground. By designing the telescopic inclined beam 1411, during the lifting movement of the vertical beam assembly 111 of the adjusting group, the telescopic inclined beam 1411 can follow the height change of the vertical beam assembly 111 to make telescopic movement, so as to adapt to the height adjustment of the vertical beam assembly 111.

[0042] As shown in FIG. 1, Figure 2 As shown in FIG. 1, the telescopic inclined beam 1411 comprises a first inclined beam 14111 and a second inclined beam 14112. The first inclined beam 14111 is rotatably connected to the top end of one of the vertical beam assemblies 111 in the corresponding vertical beam group 11; the second inclined beam 14112 is sleeved on the first inclined beam 14111 and can make relative telescopic movement with the first inclined beam 14111, and the connecting end of the second cross beam 1212 is used to be connected to the ground. By designing the first inclined beam 14111 and the second inclined beam 14112, during the lifting movement of the vertical beam assembly 111 of the adjusting group, the first inclined beam 14111 and the second inclined beam 14112 can make relative telescopic movement, so as to adapt to the height adjustment of the vertical beam assembly 111.

[0043] As shown in FIG. 1, Figure 3 , Figure 5 and Figure 6As shown, the vertical beam assembly 111 includes a first vertical beam 1111, a motor 1112, a screw rod 1113 and a second vertical beam 1114. The motor 1112 is arranged in the cavity of the first vertical beam 1111; the screw rod 1113 is located in the cavity of the first vertical beam 1111 and connected with the driving shaft of the motor 1112; the second vertical beam 1114 is sleeved with the first vertical beam 1111 and threadedly connected with the screw rod 1113, and the top end of the second vertical beam 1114 is connected with the cross beam assembly 12 (specifically, the first cross beam 1211 and the second cross beam 1212 described above). The motor 1112 is configured to drive the screw rod 1113 to rotate, so as to drive the second vertical beam 1114 to move up and down along the vertical direction relative to the first vertical beam 1111. The motor 1112 can be fixedly connected with the inner wall of the first vertical beam 1111 by means of locking screws, but is not limited thereto. When it is necessary to adjust the angle of the photovoltaic panel 13, the motor 1112 is started, the motor 1112 drives the screw rod 1113 to rotate, the screw rod 1113 drives the second vertical beam 1114 threadedly connected therewith to move up and down along the vertical direction relative to the first vertical beam 1111, so as to adjust the height of the second vertical beam 1114, thereby changing the angle of the photovoltaic panel 13, so that the light-receiving surface of the photovoltaic panel 13 can face the sun, so as to improve the power generation efficiency of the photovoltaic device 1.

[0044] It should be noted that the vertical beam assembly 111 further includes a control box (not shown in the figure), which is provided with a control button. The control button can realize multi-gear adjustment, so that the second vertical beam 1114 is at different heights and the photovoltaic panel 13 is at different angles. The user can adjust the control buttons of different vertical beam assemblies 111 to be at the same gear according to actual needs, so that the photovoltaic panel 13 is at a suitable angle. For example, the gears of the control button include a first gear, a second gear and a third gear; when the control button is at the first gear, the second vertical beam 1114 is at a first preset height, and the photovoltaic panel 13 is at a first preset angle; when the control button is at the second gear, the second vertical beam 1114 is at a second preset height, and the photovoltaic panel 13 is at a second preset angle; when the control button is at the third gear, the second vertical beam 1114 is at a third preset height, and the photovoltaic panel 13 is at a third preset angle. The user can adjust the control buttons of different vertical beam assemblies 111 to be at the same gear according to actual needs, so that the second vertical beams 1114 of two vertical beam assemblies 111 in the adjustment group move up and down to the same height, thereby changing the angle of the photovoltaic panel 13, so that the light-receiving surface of the photovoltaic panel 13 can face the sun, so as to improve the power generation efficiency of the photovoltaic device 1.

[0045] As Figure 3 , Figure 5 and Figure 6As shown, the vertical beam assembly 111 further comprises a gear 1115, a screw rod 1116, a driving handle 1117 and a pulley 1118. The gear 1115 is located in the cavity of the first vertical beam 1111 and rotationally connected with the first vertical beam 1111; the screw rod 1116 is located in the cavity of the first vertical beam 1111 and threadedly connected with the inner side of the gear 1115; the driving handle 1117 penetrates the first vertical beam 1111 and the end thereof is meshingly connected with the outer side of the gear 1115; the pulley 1118 is fixedly connected with the end of the screw rod 1116. The driving handle 1117 is configured to drive the gear 1115 to rotate under the action of external force, so as to drive the screw rod 1116 to move up and down along the vertical direction, thereby enabling the pulley 1118 to have a first state of being accommodated in the cavity of the first vertical beam 1111 and a second state of extending out of the cavity of the first vertical beam 1111. Wherein, the gear 1115 can be but not limited to rotationally connected with the inner wall of the first vertical beam 1111 through a bearing. When the photovoltaic module 10 is not needed to be moved, the user can rotate the driving handle 1117, the driving handle 1117 rotationally drives the gear 1115 meshingly connected therewith to rotate, the gear 1115 rotationally drives the screw rod 1116 threadedly connected therewith to move up along the vertical direction, thereby enabling the pulley 1118 to be in the first state of being accommodated in the cavity of the first vertical beam 1111; when the photovoltaic module needs to be moved, the user can rotate the driving handle 1117, the driving handle 1117 rotationally drives the gear 1115 meshingly connected therewith to rotate, the gear 1115 rotationally drives the screw rod 1116 threadedly connected therewith to move down along the vertical direction, thereby enabling the pulley 1118 to be in the second state of extending out of the cavity of the first vertical beam 1111, at this time the user can move the photovoltaic module 10 by means of the pulley 1118, which is simple, convenient and fast.

[0046] As shown in Figure 3 , Figure 5 and Figure 6 , the vertical beam assembly 111 further comprises a base 1119; the base 1119 is arranged at the bottom end of the first vertical beam 1111 and is fixedly connected with the ground by means of locking screws. By designing the base 1119, the base 1119 is fixedly connected with the ground by means of locking screws, thereby realizing the fixed connection between the vertical beam assembly 111 and the ground, which is convenient to operate. It should be noted that when the photovoltaic module 10 is not needed to be moved, the base 1119 is fixedly connected with the ground by means of locking screws, at this time the pulley 1118 is in the first state of being accommodated in the cavity of the first vertical beam 1111; when the photovoltaic module 10 needs to be moved, the user first removes the screws on the base 1119, and then rotates the driving handle 1117 to make the pulley 1118 be in the second state of extending out of the cavity of the first vertical beam 1111.
