Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic installation, and in particular to a wall photovoltaic structure. Background Art

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It consists of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).

[0003] Besides rooftops and open spaces, walls are also viable locations for photovoltaic installation. The advantage of wall-mounted photovoltaic systems is that they can be installed on the building's wall, further expanding the installation space. Furthermore, wall-mounted installations can enhance the building's appearance.

[0004] The optimal angle between a photovoltaic panel and sunlight refers to the angle at which the panel receives the highest sunlight intensity. The panel's output power is proportional to the intensity of the sunlight it receives. Therefore, optimizing the angle between the panel and sunlight can improve its power generation efficiency. However, when a building wall generates photovoltaic power, if there is an angle between direct sunlight and the photovoltaic panel aligned with the wall, the panel's ability to convert electricity is limited. Furthermore, photovoltaic panels installed on building walls that are not facing direct sunlight are less likely to be utilized. Summary of the Invention

[0005] The first aspect of the present invention aims to solve the technical problem that photovoltaic panels on building walls are affected by the angle of sunlight, which limits the amount of light received by the photovoltaic panels and leads to poor conversion of electrical energy. A wall photovoltaic structure is provided that can improve the power conversion effect of the photovoltaic panels by adjusting the angle of the photovoltaic panels. The main concept is:

[0006] A wall photovoltaic structure includes a photovoltaic panel and a mounting frame. The photovoltaic panel is used to receive light to generate electricity. The mounting frame is arranged on the outside of the wall and is connected to the photovoltaic panel. The mounting frame includes an upper mounting portion and a lower mounting portion. The upper mounting portion is connected to the photovoltaic panel via a hinge. The lower mounting portion is provided with a first adjustment mechanism that is transmission-connected to the photovoltaic panel. The first adjustment mechanism is used to drive the photovoltaic panel to rotate about the hinge.

[0007] The upper mounting portion is connected to the wall through a second adjusting mechanism. The second adjusting mechanism includes a gear set and a driving member for driving the gear set. The upper mounting portion is arranged opposite to the gear set, and the axis of the upper mounting portion is perpendicular to the wall.

[0008] This solution is achieved by hingedly setting the photovoltaic panel on the upper mounting part and setting a first adjustment mechanism on the lower mounting part to provide a rotational force to the photovoltaic panel, so that the photovoltaic panel is based on the vertical wall. The first adjustment mechanism causes the photovoltaic panel to rotate away from and closer to the wall around the hinge. The hinge is set on the upper mounting part. A second adjustment mechanism is set to adjust the rotation of the upper mounting part. The gear set is set relative to the upper mounting part, so that the upper mounting part can use the line of action in the direction of the vertical wall as the axis. The upper mounting part rotates to drive the photovoltaic panel with the horizontal ground as the reference. The second adjustment mechanism causes the two sides of the photovoltaic panel to rotate away from and closer to the ground. The wall photovoltaic structure of this solution can be adjusted more accurately according to the direction of sunlight, so that the daily working efficiency of the photovoltaic panel is maximized.

[0009] Preferably, the first adjustment mechanism includes a linear motion assembly and an adjustment rod, wherein the linear motion assembly is vertically mounted on the lower mounting base. The linear motion assembly includes a lifting portion, wherein the output end of the lifting portion is provided with a hinged portion, one end of the adjustment rod is hingedly connected to the hinged portion of the lifting portion, and the other end of the adjustment rod is hingedly connected to the photovoltaic panel. Through adjustment of the lifting portion of the linear motion assembly, the adjustment rod, which is connected to the lifting portion for transmission, controls the angle between the photovoltaic panel and the wall.

[0010] Preferably, a positioning groove is provided on the side of the lower mounting portion away from the wall, and the positioning groove is used to limit the distance between the photovoltaic panel and the wall. The positioning groove can control the photovoltaic panel to be parallel to the wall, making the photovoltaic panel more beautiful when not deployed.

[0011] Preferably, the first adjustment mechanism adjusts the angle of the photovoltaic panel to a range of 0°-90°. When the adjustment angle of the photovoltaic panel is 90°, the lifting part of the linear motion assembly is located at the maximum critical point of the output. When the lifting part is at the highest point, the second adjustment mechanism starts to drive the upper mounting part to rotate.

[0012] Preferably, the gear set includes a driving wheel and an inner ring gear, the driving wheel is in transmission connection with the inner ring gear, the inner ring gear is installed on the outer wall through a mounting base, the inner ring gear includes a baffle and a connecting piece outside the baffle, and the inner ring gear is in transmission connection with the upper mounting part through the connecting piece.

[0013] The second aspect of this aspect is to solve the problem that when the second adjustment component controls the movement of the upper mounting part, the photovoltaic panel installed on the upper mounting part has a certain weight, which will cause the downward force of the second adjustment component to be too large. Because of the stress concentration, the second adjustment mechanism will fail to connect to the wall. Furthermore, the mounting base includes a gear ring seat and a support shaft. A positioning hole is provided at the center of the baffle, and a connecting hole is provided on the upper mounting part. The support shaft passes through the positioning hole and is connected to the connecting hole of the upper mounting part. In order to make the installation of the second adjustment mechanism on the outer wall more stable, this solution provides a gear ring seat to position and install the inner gear ring, and also provides a support shaft to pass through the inner gear ring to act on the upper mounting part; on the one hand, the support shaft performs secondary positioning on the inner gear ring and the upper mounting part, and on the other hand, the support shaft fixed to the wall can directly provide support to the upper mounting part, disperse the force of the upper mounting part acting on the inner gear ring, and improve the connection strength between the second adjustment mechanism and the wall, thereby improving the service life of the second adjustment mechanism.

[0014] The third aspect of the present invention aims to solve the technical problem that when the upper mounting portion rotates, the adjusting rod will constrain the photovoltaic panel from deflecting with respect to the horizontal ground. Furthermore, a connecting portion is provided on the inner side of the photovoltaic panel, and the connecting portion of the photovoltaic panel and the connecting position of the adjusting rod form a ball-shaped hinge pair, the connecting portion of the photovoltaic panel is provided with a spherical groove, and the end of the adjusting rod is provided with a spherical head that cooperates with the spherical groove. This solution sets the mounting position of the photovoltaic panel and the first adjusting mechanism to a spherical hinge structure, so that the photovoltaic panel can perform multi-degree-of-freedom movement on the adjusting rod, and the cooperation between the adjusting rod and the connecting portion will not interfere with the upward and downward deflection movement of the photovoltaic panel on both sides of the hinge axis.

[0015] Preferably, the connecting portion is installed in the middle of the photovoltaic panel, the projection of the connecting portion's rotation center on the ground reference coincides with the projection of the inner gear ring's axis on the ground reference, and the deflection angle of the upper mounting portion is less than 45°. By arranging the projection of the connecting portion's rotation center and the inner gear ring's axis on the ground reference to coincide, when the angle between the photovoltaic panel and the wall reaches 90°, the line connecting the connecting portion 12 to the hinge coincides with the rotation axis of the inner gear ring. When the inner gear ring drives the photovoltaic panel to deflect, the connecting portion located at the rotation axis position will not deviate, thereby ensuring a stable connection between the connecting portion and the adjustment rod. The deflection angle of the upper mounting portion is set to less than 45°, so that the spherical head of the adjustment rod does not exceed the critical deflection point with the spherical groove of the connecting portion.

[0016] Preferably, the photovoltaic panel includes decorative glass and photovoltaic cells, and the photovoltaic cells are arranged between the decorative glass. The decorative glass can be customized according to the characteristics of the building, so that the photovoltaic panel can decorate the wall surface, and the photovoltaic cells arranged between the decorative glass convert light energy into electrical energy.

[0017] The beneficial effects of the present invention are: the photovoltaic panel is hingedly arranged on the upper mounting part, and a first adjustment mechanism for providing a rotational force to the photovoltaic panel is arranged on the lower mounting part, so that the photovoltaic panel is based on the vertical wall. The first adjustment mechanism allows the photovoltaic panel to rotate away from and closer to the wall around the hinge. The hinge is arranged on the upper mounting part, and a second adjustment mechanism is provided to adjust the rotation of the upper mounting part. The gear set is arranged relative to the upper mounting part, so that the upper mounting part can use the line of action in the direction perpendicular to the wall as the axis. The upper mounting part rotates to drive the photovoltaic panel with the horizontal ground as the reference. The second adjustment mechanism allows the two sides of the photovoltaic panel to rotate away from and closer to the ground. The wall photovoltaic structure of this scheme can be adjusted more accurately according to the direction of sunlight, so that the daily working efficiency of the photovoltaic panel is maximized.

[0026] It should be noted that all actions of obtaining signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0027] In this disclosure, unless otherwise specified, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" are used in this disclosure to distinguish one element from another and do not convey order or importance.

[0028] Example 1

[0029] like Figures 1-6 As shown, this embodiment provides a wall photovoltaic structure, including a photovoltaic panel 1 and a mounting frame 2. The photovoltaic panel is used to receive light to generate electricity. The mounting frame 2 is set on the outside of the wall and is connected to the photovoltaic panel 1. The mounting frame 2 includes an upper mounting portion 21 and a lower mounting portion 22. The upper mounting portion 21 is connected to the photovoltaic panel 1 through a hinge 3. The lower mounting portion 22 is provided with a first adjustment mechanism 4 that is transmission-connected to the photovoltaic panel 1. The first adjustment mechanism 4 is used to drive the photovoltaic panel 1 to rotate around the hinge 3.

[0030] The upper mounting portion 21 is connected to the wall through the second adjusting mechanism 5. The second adjusting mechanism 5 includes a gear set and a driving member for driving the gear set. The upper mounting portion 21 is arranged opposite to the gear set, and the axis of the upper mounting portion 21 is perpendicular to the wall.

[0031] In this embodiment, the photovoltaic panel 1 is hingedly arranged on the upper mounting part 21, and a first adjustment mechanism 4 for providing a rotational force to the photovoltaic panel 1 is arranged on the lower mounting part 22, so that the photovoltaic panel 1 is based on the vertical wall. The first adjustment mechanism 4 allows the photovoltaic panel 1 to rotate away from and closer to the wall around the hinge 3. The hinge 3 is arranged on the upper mounting part 21. A second adjustment mechanism 5 is provided to adjust the rotation of the upper mounting part 21. The gear set is arranged relative to the upper mounting part 21, so that the upper mounting part 21 can use the line of action in the direction perpendicular to the wall as the axis. The upper mounting part 21 rotates to drive the photovoltaic panel 1 with the horizontal ground as the reference. The second adjustment mechanism 5 allows the two sides of the photovoltaic panel 1 to rotate away from and closer to the ground. The wall photovoltaic structure of this scheme can be adjusted more accurately according to the direction of sunlight, so that the daily working efficiency of the photovoltaic panel 1 is maximized.

[0032] The first adjustment mechanism 4 of this embodiment includes a linear motion assembly 41 and an adjustment rod 42. The linear motion assembly 41 is vertically mounted on the lower mounting base 22. The linear motion assembly 41 includes a lifting portion, and a hinge portion 44 is provided at the output end of the lifting portion. One end of the adjustment rod 42 is hingedly connected to the hinge portion 44 of the lifting portion, and the other end of the adjustment rod 42 is hingedly connected to the photovoltaic panel 1. Through the adjustment of the lifting portion of the linear motion assembly 41, the adjustment rod 42, which is connected to the lifting portion for transmission, controls the angle between the photovoltaic panel 1 and the wall.

[0033] In this embodiment, the linear motion assembly 41 adopts a cylinder structure, comprising a cylinder and a piston rod, with the piston rod acting as a lifting part and performing lifting motion under the action of the cylinder. Alternatively, the linear motion assembly may adopt a hydraulic cylinder structure and a transmission screw, etc., which can enable the lifting part to perform linear motion.

[0034] Preferably, a positioning groove 221 is provided on the side of the lower mounting portion 22 away from the wall, and the positioning groove 211 is used to limit the distance between the photovoltaic panel 1 and the wall. The positioning groove 211 can control the photovoltaic panel to be parallel to the wall, making the photovoltaic panel 1 more beautiful when it is not deployed.

[0035] In order to make the photovoltaic panel receive light better, the first adjustment mechanism 4 adjusts the photovoltaic panel 1 to an angle within a range of 0°-90°, such as Figure 5 As shown, the angle between the photovoltaic panel 1 and the wall is about 45°, and the photovoltaic panel 1 can be adjusted to this state by the first adjustment mechanism 4 on the wall of the building that is directly exposed to sunlight.

[0036] When the photovoltaic panel 1 is adjusted to a 90° angle, the lifting portion of the linear motion assembly 41 is at the critical point of maximum output. When the lifting portion is at its highest point, the second adjustment mechanism 5 begins to drive the upper mounting portion 21 to rotate. The state where the photovoltaic panel 1 forms a 90° angle with the wall is set as the highest point of the lifting portion's movement within the linear motion assembly 41. This ensures that when the lifting portion reaches its highest point, the angle between the photovoltaic panel 1 and the wall does not continue to change. The upward rotation of the photovoltaic panel 1 is positioned by the linear motion assembly 41, while the downward rotation of the photovoltaic panel 1 is positioned by the positioning slot 221 of the lower mounting portion 22.

[0037] like Figure 5 As shown, the angle between the photovoltaic panel 1 and the wall is between 0° and 90°, which is the adjustment state of the photovoltaic panel 1 installed on the wall on the side directly exposed to sunlight.

[0038] Example 2:

[0039] When installing photovoltaic equipment on a wall, the load-bearing capacity and structural safety of the wall need to be considered. In addition, the orientation of the wall and the sunlight exposure will also affect the power generation efficiency of the photovoltaic equipment. For a building, there is a surface opposite to the direction of the sun's trajectory, and there are also walls on both sides that are not directly exposed to sunlight. The photovoltaic panels 1 on the side exposed to sunlight are adjusted by the first adjustment mechanism 4 to adjust the angle between the photovoltaic panels 1 and the wall. For the photovoltaic panels on the walls on both sides that are not directly exposed to sunlight, the photovoltaic panels 1 are opened 90° by the first adjustment mechanism 4, and then the second adjustment mechanism 5 of this embodiment is used to deflect the photovoltaic panels 1 by rotating the upper mounting portion 21. The deflected photovoltaic panels 1 can form an angle with the wall on the side directly exposed to sunlight, and the photovoltaic panels 1 face the sunlight. The photovoltaic structure of the present invention can maximize the utilization of the photovoltaic panels on the wall of the building.

[0040] like Figure 3-Figure 4 As shown, the gear set of this embodiment includes a driving wheel 51 and an inner ring gear 52, which are in driving connection with the inner ring gear 52. The inner ring gear 52 is mounted on the outer wall via a mounting base. The inner ring gear 52 includes a baffle 521 and a connector 522 outside the baffle 521. The inner ring gear 52 is in driving connection with the upper mounting portion 21 via the connector 522. The transmission of the gear set enables the photovoltaic panel mounted on the upper mounting portion 21 to deflect on both sides of the hinge 3.

[0041] The mounting base of this embodiment includes a gear ring seat 55 and a support shaft 54. A positioning hole is provided at the center of the baffle 521, and a connecting hole is provided on the upper mounting portion 21. The support shaft 54 ​​passes through the positioning hole and is connected to the connecting hole of the upper mounting portion 21. In order to make the installation of the second adjustment mechanism 5 on the exterior wall more stable, this solution provides a gear ring seat 55 to position and install the inner gear ring 52, and also provides a support shaft 54 ​​to pass through the inner gear ring 52 and act on the upper mounting portion 21. On the one hand, the support shaft 54 ​​performs secondary positioning of the inner gear ring 52 and the upper mounting portion 21. On the other hand, the support shaft 54 ​​fixed to the wall can directly provide support for the upper mounting portion 21, dispersing the force of the upper mounting portion 21 acting on the inner gear ring 52, improving the connection strength between the second adjustment mechanism 5 and the wall, and thus improving the service life of the second adjustment mechanism 5.

[0042] Bearings are provided in the positioning hole of the baffle 521 and the connecting hole of the upper mounting portion 21 , so that the positioning hole and the connecting hole are transmission-connected to the support shaft 54 ​​through the bearings.

[0043] Specifically, this solution uses the meshing method of the driving wheel 51 and the inner gear ring 52 to achieve high-precision operation, and the gear set of this embodiment is set on a vertical wall. The outer teeth of the driving wheel 51 are meshed with the inner teeth at the upper end of the inner gear ring 52. The driving wheel 51 is driven by the driving member 53. The driving wheel 1 is located between the inner tooth edge of the inner gear ring 51 and the support shaft, so that the support shaft 54 ​​will not interfere with the rotation of the driving wheel when it is installed.

[0044] Since the support shaft 54 ​​and the inner gear ring 52 are coaxially arranged, the connection hole of the upper mounting portion 21 on which the end of the support shaft 54 ​​acts becomes the rotation center when the upper mounting portion 21 and the inner gear ring 52 rotate synchronously.

[0045] The mounting base of this embodiment can be installed on the wall through a mounting beam, and the working panel is connected to the mounting beam by welding. Holes are drilled on the working panel so that the gear ring seat 55 and the support shaft 54 ​​can be installed on the vertical working panel by bolt connection, avoiding the mounting base from directly acting on the wall, which not only avoids damage to the wall, but also facilitates the disassembly and assembly of the photovoltaic structure.

[0046] Example 3:

[0047] like Figures 1-6 As shown, in this embodiment, a connection portion 12 is provided on the inner side of the photovoltaic panel 1. The connection between the connection portion 12 of the photovoltaic panel 1 and the adjustment rod 42 forms a ball-jointed joint. The connection portion 12 of the photovoltaic panel 1 defines a spherical groove, and the end of the adjustment rod 42 defines a spherical head 43 that mates with the spherical groove. By configuring the mounting position of the photovoltaic panel 1 and the first adjustment mechanism 4 as a spherical hinge structure, this solution allows the photovoltaic panel 1 to perform multi-degree-of-freedom movement on the adjustment rod 42. The coordination between the adjustment rod 42 and the connection portion 12 does not interfere with the upward and downward deflection of the photovoltaic panel 1 on either side of the axis of the hinge 3.

[0048] like Figure 6 As shown, the connection part 12 is installed in the middle of the photovoltaic panel 1. The projection of the rotation center of the connection part 12 on the ground reference coincides with the projection of the axis of the inner gear ring 52 on the ground reference. The deflection angle of the photovoltaic panel 1 is less than 45°. By arranging the projection of the rotation center of the connection part 12 and the axis of the inner gear ring on the ground reference to coincide, when the angle between the photovoltaic panel 1 and the wall reaches 90°, the rotation center of the connection part 12 coincides with the rotation axis of the inner gear ring 52; Figure 6As shown, when the inner gear ring 52 drives the photovoltaic panel 1 to deflect, the connecting portion 12 located at the rotation axis position will not deviate, so that the connecting portion 12 is stably connected to the adjustment rod 42. In addition, because the lifting portion and the adjustment rod 42 provided by the linear motion component 41 of the first adjustment mechanism 4 are realized by a hinge seat, the adjustment rod 42 can only move along the rotation axis direction of the hinge 3. When the photovoltaic panel 1 rotates to form a 90° angle with the wall, when the photovoltaic panel 1 deflects under the action of the second adjustment mechanism 5, the adjustment rod 42 will not deflect synchronously under the restraint of the hinge 3, and does not provide stable support for the photovoltaic panel 1, so that the spherical groove of the connecting portion 12 of the photovoltaic panel 1 rotates in coordination with the spherical head 43.

[0049] The deflection angle of the photovoltaic panel 1 is set to be less than 45°, so that the spherical head 43 of the adjustment rod 42 does not exceed the deflection critical point with the spherical groove of the connecting portion 12 .

[0050] like Figure 2 and Figure 6 As shown, when the photovoltaic panel 1 is adjusted to 90 degrees by the first adjustment mechanism 4 , the center of the spherical groove of the connecting portion 12 installed on the photovoltaic panel 1 is located on the extended axis of the inner gear ring.

[0051] The photovoltaic panel 1 includes decorative glass and photovoltaic cells, which are arranged between the decorative glass. The decorative glass can be customized according to the characteristics of the building, so that the photovoltaic panel can be used to decorate the wall. The photovoltaic cells arranged between the decorative glass convert light energy into electrical energy.

[0052] The above is only an embodiment of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
