Description

Technical Field

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

[0002] Photovoltaic panel components are power generation devices that generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).

[0003] In addition to roofs and open spaces, walls are also feasible locations for installing photovoltaic equipment. The advantage of installing photovoltaic equipment on a wall is that it can be installed on the wall of a building, further expanding the installation space. At the same time, wall installation can also beautify the appearance of the building.

[0004] The optimal angle between the photovoltaic panel and the sunlight refers to the angle at which the photovoltaic panel receives the highest intensity of sunlight. The output power of the photovoltaic panel is proportional to the intensity of sunlight it receives. Therefore, the optimal angle between the photovoltaic panel and the sunlight can improve the power generation efficiency of the photovoltaic panel. When the building wall is performing photovoltaic function, if there is an angle between the direct sunlight and the photovoltaic panel attached to the building wall, the effect of the photovoltaic panel in converting electricity will be limited, and the photovoltaic panels installed on the building wall that are not opposite to the direct sunlight will be difficult to be used. Summary of the invention

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

[0006] A wall photovoltaic structure, comprising a photovoltaic panel and a mounting frame, wherein the photovoltaic panel is used to receive light to generate electricity, the mounting frame is arranged outside the wall, the mounting frame is connected to the photovoltaic panel, the mounting frame comprises an upper mounting portion and a lower mounting portion, the upper mounting portion is connected to the photovoltaic panel through a hinge, the lower mounting portion is provided with a first adjustment mechanism which is transmission-connected to the photovoltaic panel, and the first adjustment mechanism is used to drive the photovoltaic panel to rotate around the hinge;

[0007] The upper mounting part 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 to operate. The upper mounting part is arranged opposite to the gear set, and the axis of the upper mounting part is perpendicular to the wall.

[0008] In this solution, the photovoltaic panel is hingedly arranged on the upper mounting part, and a first adjusting 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 adjusting 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 adjusting mechanism is arranged 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 of the vertical wall as the axis. The upper mounting part rotates to drive the photovoltaic panel to use the horizontal ground as the reference, and the second adjusting mechanism allows 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 component and an adjustment rod, the linear motion component is vertically mounted on the lower mounting seat, the linear motion component includes a lifting part, a hinged part is arranged at the output end of the lifting part, one end of the adjustment rod is hingedly connected to the hinged part of the lifting part, and the other end of the adjustment rod is hingedly connected to the photovoltaic panel. By adjusting the lifting part of the linear motion component, the adjustment rod connected to the lifting part 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 photovoltaic panel can be controlled to be parallel to the wall through the positioning groove, 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 gear ring, the driving wheel is transmission connected to the inner gear ring, the inner gear ring is installed on the outer wall through a mounting base, the inner gear ring includes a baffle and a connecting piece outside the baffle, and the inner gear ring is transmission connected to 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. Further, 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 scheme sets a gear ring seat to position and install the inner gear ring, and also sets 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 movement relative 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 head 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 as 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 up and down deflection movement of the photovoltaic panel on both sides of the axis of the hinge.

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

[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 as follows: the photovoltaic panel is hingedly arranged on the upper mounting part, and a first adjusting 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, and the first adjusting mechanism allows the photovoltaic panel to rotate around the hinge away from and close to the wall. The hinge is arranged on the upper mounting part, and a second adjusting mechanism is arranged 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 of the vertical wall as the axis. The upper mounting part rotates to drive the photovoltaic panel to use the horizontal ground as the reference, and the second adjusting mechanism allows the two sides of the photovoltaic panel to rotate away from and close 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.

[0028] Example 1

[0029] like Figure 1-Figure 6 As shown, a wall photovoltaic structure provided in this embodiment includes 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 arranged outside the wall, the mounting frame 2 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 and is transmission-connected to the photovoltaic panel 1, and 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 adjusting 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 adjusting mechanism 4 allows the photovoltaic panel 1 to rotate away from and close to the wall around the hinge 3. The hinge 3 is arranged on the upper mounting part 21. A second adjusting mechanism 5 is arranged 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 to use the horizontal ground as the reference. The second adjusting mechanism 5 allows the two sides of the photovoltaic panel 1 to rotate away from and close 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 component 41 and an adjustment rod 42. The linear motion component 41 is vertically mounted on the lower mounting seat 22. The linear motion component 41 includes a lifting part. The output end of the lifting part is provided with a hinge part 44. One end of the adjustment rod 42 is hingedly connected to the hinge part 44 of the lifting part, and the other end of the adjustment rod 42 is hingedly connected to the photovoltaic panel 1. Through the adjustment of the lifting part of the linear motion component 41, the adjustment rod 42 connected to the lifting part 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, which consists of a cylinder and a piston rod, and the piston rod acts as a lifting part to perform lifting motion under the action of the cylinder. In addition, the linear motion assembly can also adopt a hydraulic cylinder structure and a transmission screw structure that 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 photovoltaic panel can be controlled to be parallel to the wall through the positioning groove 211, making the photovoltaic panel 1 more beautiful when not unfolded.

[0035] In order to make the photovoltaic panel receive light better, the first adjustment mechanism 4 adjusts the photovoltaic panel 1 to an angle ranging from 0° to 90°. 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 through the first adjustment mechanism 4 on the wall of the building that is directly exposed to sunlight.

[0036] When the adjustment angle of the photovoltaic panel 1 is 90°, the lifting part of the linear motion assembly 41 is located at the maximum critical point of the output. When the lifting part is at the highest point, the second adjustment mechanism 5 starts to drive the upper mounting part 21 to rotate. The state when the photovoltaic panel 1 forms an angle of 90° with the wall is set as the highest point of the lifting part running in the linear motion assembly 41, so that when the lifting part moves to the highest point, the angle between the photovoltaic panel 1 and the wall will not continue to change. The upward rotation of the photovoltaic panel 1 is positioned by the linear motion assembly 41, and the downward rotation of the photovoltaic panel 1 is positioned by the positioning groove 221 of the lower mounting part 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] Embodiment 2:

[0039] When installing photovoltaic equipment on the 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 panel 1 on the side that is exposed to sunlight is adjusted by the first adjustment mechanism 4 to adjust the angle between the photovoltaic panel 1 and the wall. For the photovoltaic panels on the walls on both sides that are not directly exposed to sunlight, the photovoltaic panel 1 is opened 90° by the first adjustment mechanism 4, and then the photovoltaic panel 1 is deflected by the rotation of the upper mounting part 21 by the second adjustment mechanism 5 of this embodiment. The deflected photovoltaic panel 1 can form an angle with the wall on the side where the sunlight is directly exposed. The photovoltaic panel 1 faces the sunlight. The photovoltaic structure of the present invention can make the maximum use 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 gear ring 52, the driving wheel 52 is in transmission connection with the inner gear ring 52, the inner gear ring 52 is installed on the outer wall through a mounting base, the inner gear ring 52 includes a baffle 521 and a connecting member 522 outside the baffle 521, and the inner gear ring 52 is in transmission connection with the upper mounting portion 21 through the connecting member 522. The transmission of the gear set enables the photovoltaic panel installed 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 outer wall more stable, the gear ring seat 55 is provided to position and install the inner gear ring 52, and a support shaft 54 ​​is also provided to pass through the inner gear ring 52 to act on the upper mounting portion 21; on the one hand, the support shaft 54 ​​performs secondary positioning on the inner gear ring 52 and the upper mounting portion 21, and on the other hand, the support shaft 54 ​​fixed to the wall can directly provide support to the upper mounting portion 21, disperse the force of the upper mounting portion 21 acting on the inner gear ring 52, and improve the connection strength between the second adjustment mechanism 5 and the wall, thereby improving the service life of the second adjustment mechanism 5.

[0042] Bearings are arranged 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 with the support shaft 54 ​​through the bearings.

[0043] Specifically, this solution adopts the meshing mode of the driving wheel 51 and the inner gear ring 52 to achieve high-precision operation, and the gear set of this embodiment is arranged 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, and 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 is the rotation center when the upper mounting portion 21 and the inner gear ring 52 rotate synchronously.

[0045] The mounting base of the present 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, thereby 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] Embodiment 3:

[0047] like Figure 1-Figure 6 As shown, in this embodiment, a connection part 12 is provided on the inner side of the photovoltaic panel 1, and the connection position of the connection part 12 of the photovoltaic panel 1 and the adjustment rod 42 forms a ball head hinge pair, the connection part 12 of the photovoltaic panel 1 is provided with a spherical groove, and the end of the adjustment rod 42 is provided with a spherical head 43 that cooperates with the spherical groove. In this solution, by setting the installation position of the photovoltaic panel 1 and the first adjustment mechanism 4 as a spherical hinge structure, the photovoltaic panel 1 can perform multi-degree-of-freedom movement on the adjustment rod 42, and the cooperation between the adjustment rod 42 and the connection part 12 will not interfere with the up and down deflection movement of the photovoltaic panel 1 on both sides 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, and 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 connection part 12 located at the rotation axis position will not be offset, so that the connection part 12 is stably connected to the adjustment rod 42. In addition, since the lifting part 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 constraint of the hinge 3, and provide stable support for the photovoltaic panel 1, so that the spherical groove of the connection part 12 of the photovoltaic panel 1 rotates in coordination with the spherical head 43.

[0049] And 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 part 12 .

[0050] like Figure 2 and Figure 6 As shown, when the photovoltaic panel 1 is adjusted to 90° 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 line of the axis of the inner gear ring.

[0051] The photovoltaic panel 1 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.

[0052] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope 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.
