[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1-6 As shown, the adjustable photovoltaic support device according to the embodiment of the present invention includes: a first column 11 , a second column 12 , a rotating assembly 4 , a first rope 21 , a second rope 22 and a photovoltaic panel 6 .

[0034] The first column 11 and the second column 11 are arranged in a first direction (eg Figure 1 The rotating assembly 4 includes a first rotating member 41 and a second rotating member 42. The first rotating member 41 is rotatably mounted on the first column 11 around a first axis, and the second rotating member 42 is rotatably mounted on the second column 12 around a first axis. Figure 1 As shown, the extension direction of the first axis is parallel to the front-rear direction.

[0035] A portion of the first rope 21 is connected between the first column 11 and the second column 12 , and the portion of the first rope 21 is movable in a first direction.

[0036] It should be noted that the length of the first rope 21 is greater than the spacing distance between the first column 11 and the second column 12 in the first direction. When the first rope 21 moves along the first direction, the first rope 21 connected between the first column 11 and the second column 12 is a different part of the first rope 21, that is, this part of the first rope 21 is dynamic and changes during the movement, but the total length of the first rope 21 and the length of the part of the first rope 21 connected between the first column 11 and the second column 12 remain unchanged.

[0037] At least a portion of the second rope 22 is connected between the first rotating member 41 and the second rotating member 42 , and at least one of the portion of the first rope 21 and at least a portion of the second rope 22 is rotatable about the first axis.

[0038] That is, part of the first rope 21 is rotatable around the first axis, or part of the second rope 22 is rotatable around the first axis, or both parts of the first rope 21 and the second rope 22 are rotatable around the first axis.

[0039] The adjustable photovoltaic support device of the embodiment of the present invention can use the rotating component to rotate around the first axis to drive the second rope to rotate, so as to adjust the light receiving angle of the photovoltaic panel, so that the photovoltaic panel can be fully exposed to sunlight and improve the power generation efficiency of the photovoltaic panel.

[0040] Therefore, the adjustable photovoltaic support device according to the embodiment of the present invention can adjust the light receiving angle of the photovoltaic panel so that the photovoltaic panel receives sufficient light.

[0041] In some embodiments, the adjustable photovoltaic support device of an embodiment of the present invention also includes a first support assembly 31 and a second support assembly 32. The first support assembly 31 is arranged on the first rope 21, and the first support assembly 31 is rotatable around the second axis. The second support assembly 32 is fixed on the second rope 22. The extension direction of the first axis is perpendicular to the extension direction of the second axis. The photovoltaic panel 6 is fixed on the first support assembly 31, and the photovoltaic panel 6 is rotatably arranged on the second support assembly 22 around the first axis.

[0042] It can be understood that when the first rope 21 is driven to move in the left and right directions, the first rope 21 drives the first support assembly 31 to rotate around the first axis, so that the photovoltaic panel 6 fixed on the first support assembly 31 rotates synchronously with the first support assembly 31, thereby adjusting the tilt angle of the photovoltaic panel 6 to the left or right.

[0043] Drive at least a portion of the second rope 22 and at least one of the portions of the first rope 21 to move in the up and down directions, so that the first support assembly 31 and the second support assembly 32 are separated by a certain distance in the up and down directions, thereby making the photovoltaic panel 6 tilt forward or backward, and by adjusting the distance between the first support assembly 31 and the second support assembly 32 in the up and down directions, the angle at which the photovoltaic panel 6 tilts forward or backward can be controlled.

[0044] For example, the first support assembly 31 is located behind the second support assembly 32 , and the first support assembly 31 is higher than the second support assembly 32 , thereby causing the photovoltaic panel 6 to tilt forward at a certain angle.

[0045] In some embodiments, as Figure 3 and Figure 4As shown, the first supporting assembly 31 includes a first connecting frame 311 , a first engaging member 312 , a pressing wheel 313 and a second engaging member 314 .

[0046] The first connecting frame 311 is used to be fixed on the back side of the photovoltaic panel 6 (such as Figure 1 The lower surface of the photovoltaic panel 6).

[0047] The first engaging member 312 is fixed on the first connecting frame 311, and the pressing wheel 313 is rotatably provided on the first connecting frame 311 around the first axis. The first engaging member 312 and the pressing wheel 313 are arranged in the height direction of the first connecting frame 311 (such as Figure 1 The first engaging member 312 is arranged at intervals (in the upper and lower directions), and the first engaging member 312 has a cylindrical surface adjacent to the pressure wheel 313 in the height direction of the first connecting frame 311. The cylindrical surface of the first engaging member 312 is provided with engaging teeth arranged along its circumference, and the extension direction of the first axis is perpendicular to the height direction of the first connecting frame 311.

[0048] The second engaging member 314 is fixed to a portion of the first rope 21. The second engaging member 314 is located between the pressure wheel 313 and the first engaging member 312 in the height direction of the first connecting frame 311. The second engaging member 314 includes a front face and a back face. The front face of the second engaging member 314 is provided with a longitudinal direction of the second engaging member 314 (such as Figure 1 The first engaging member 312 has meshing teeth arranged in the left and right directions (in the left and right directions). The cylindrical surface of the first engaging member 312 meshes with the front surface of the second engaging member 314. The pressure wheel 313 contacts the back surface of the second engaging member 314. The length direction of the second engaging member 314 is perpendicular to the extension direction of the first axis. The pressure wheel 313 is used to press the first and second engaging members 312, 314 together to ensure that the first and second engaging members 312, 314 are in a meshing state.

[0049] It can be understood that the photovoltaic panel 6 is connected to the first support assembly 31 and the second support assembly 32. When the first rope 21 moves in the left and right directions, the first support assembly 31 is restricted by the second support assembly 32 and will not move synchronously with the first rope 21. Relative movement occurs between the first engagement member 312 and the second engagement member 314, that is, the second engagement member 314 moves horizontally and the first engagement member 312 rotates, so that the first engagement member 312 drives the first connecting frame 311 to rotate around the first axis. Therefore, by driving the first rope 21 to move in the left and right directions, the tilt angle of the photovoltaic panel 6 to the left or right can be adjusted.

[0050] It should be noted that when relative movement occurs between the first engaging member 312 and the second engaging member 314, the pressure wheel 313 limits the relative movement of the first engaging member 312 and the second engaging member 314 in the height direction of the first connecting frame 311, and the second engaging member 314 will rotate a certain angle following the first engaging member 312. The second engaging member 314 is connected to the first rope 21, and the part where the first rope 21 is connected to the second engaging member 314 is deformed, thereby not limiting the rotation of the second engaging member 314.

[0051] In addition, the pressure wheel 313 is used to press the first engaging member 312 and the second engaging member 314 together to ensure that the first engaging member 312 and the second engaging member 314 are in an engaged state, and the pressure wheel 313 is rotatably arranged on the first connecting frame 311 to ensure that the pressure wheel 313 does not affect the relative movement between the first engaging member 312 and the second engaging member 314.

[0052] In some optional embodiments, such as Figure 3 As shown, the pressure wheel 313 is located above the second engaging member 314 , and the first engaging member 312 is located below the second engaging member 314 .

[0053] Specifically, the first connecting frame 311 includes a first connecting rod 3111 and a second connecting rod 3112. The first connecting rod 3111 is fixedly connected to the second connecting rod 3112. The first engaging member 312 is fixedly connected to the first connecting rod 3111. The pressure wheel 313 is rotatably disposed on the second connecting rod 3112 around its rotation axis. The rotation axis of the pressure wheel 313 is consistent with the second direction.

[0054] In other optional embodiments, such as Figure 4 As shown, the pressure wheel 313 is located below the second engaging member 314 , and the first engaging member 312 is located above the second engaging member 314 .

[0055] Specifically, the first connecting frame 311 includes a first connecting rod 3111 and a second connecting rod 3112. The first engaging member 312 is fixedly connected to the first connecting rod 3111. The second connecting rod 3112 is fixed to the first engaging member 312. The pressure wheel 313 is rotatably mounted on the second connecting rod 3112 around its rotation axis. The rotation axis of the pressure wheel 313 is aligned with the second direction.

[0056] In some embodiments, a protrusion extending along the length direction of the second engaging member 314 is provided on the back surface of the second engaging member 314 , and an annular groove cooperating with the protrusion is provided on the circumference of the pressing wheel 313 .

[0057] It can be understood that the annular groove of the pressure wheel 313 cooperates with the protrusion of the second engaging member 314, which not only enables the second engaging member 314 to guide the first engaging member 312, but also makes it difficult for the pressure wheel 313 to separate from the second engaging member 314, affecting the pressing effect of the pressure wheel 313 on the first engaging member 312 and the second engaging member 314, ensuring that the first engaging member 312 and the second engaging member 314 are in an engaged state.

[0058] In some embodiments, a groove extending along the length direction of the second engaging member 314 is provided on the back surface of the second engaging member 314 , and an annular protrusion matching the groove is provided on the circumference of the pressure wheel 313 .

[0059] It can be understood that the annular protrusion of the pressure wheel 313 cooperates with the groove of the second engaging member 314, which not only enables the second engaging member 314 to guide the first engaging member 312, but also makes it difficult for the pressure wheel 313 to separate from the second engaging member 314, affecting the pressing effect of the pressure wheel 313 on the first engaging member 312 and the second engaging member 314, ensuring that the first engaging member 312 and the second engaging member 314 are in an engaged state.

[0060] Preferably, if Figure 3 and Figure 4 As shown, the first engagement member 312 is an arc-shaped rack or gear, and the second engagement member 314 is a straight rack.

[0061] In some embodiments, as Figure 3 and Figure 4 As shown, the first connecting frame 311 is an axisymmetric structure, and the extension direction of the symmetry axis of the first connecting frame 311 is the same as the height direction of the first connecting frame 311 (such as Figure 1 The up and down directions in the diagram are consistent.

[0062] Specifically, there are two first connecting rods 3111 , one first connecting rod 3111 is connected to the left end of the first engaging member 312 , and the other first connecting rod 3111 is connected to the right end of the first engaging member 312 .

[0063] It is understandable that the first connecting frame 311 is an axisymmetric structure, so that the first connecting frame 311 can be evenly stressed when supporting the photovoltaic panel 6 , thereby improving the stability of the first connecting frame 311 .

[0064] In some embodiments, as Figure 5 As shown, the second support assembly 32 includes a second connecting frame 321 and a rotating member 322. The second connecting frame 321 is fixed to at least a portion of the second rope 22. The rotating member 322 is rotatably provided on the second connecting frame 321 around a first axis. The rotating member 322 is connected to the photovoltaic panel 6.

[0065] It can be understood that the rotating member 322 is rotatably provided on the second connecting frame 321 around the first axis, so that the photovoltaic panel 6 can be rotatably provided on the second support assembly 32 around the first axis. When the first support assembly 31 rotates around the first axis, the second support assembly 32 can rotate synchronously with the first support assembly 31, ensuring that the photovoltaic panel 6 can rotate synchronously with the first support assembly 31.

[0066] In some embodiments, as Figure 1 As shown, there are multiple first support assemblies 31 , multiple second support assemblies 32 , and multiple photovoltaic panels 6 . The multiple first support assemblies 31 correspond one-to-one to the multiple photovoltaic panels 6 , and the multiple second support assemblies 32 correspond one-to-one to the multiple photovoltaic panels 6 .

[0067] Specifically, the adjustable photovoltaic support device according to an embodiment of the present invention includes multiple mounting groups, which are spaced apart in the left-right direction. Each mounting group includes a first support assembly 31 and a second support assembly 32, wherein the first support assembly 31 is mounted on a portion of the first rope 21, and the second support assembly 32 is mounted on at least a portion of the second rope 22. The first support assembly 31 and the second support assembly 32 in a mounting group are connected to a photovoltaic panel 6.

[0068] It is understandable that the adjustable photovoltaic support device according to the embodiment of the present invention has multiple first support assemblies 31 and multiple second support assemblies 32 , so that the adjustable photovoltaic support device according to the embodiment of the present invention can be installed with multiple photovoltaic panels 6 .

[0069] In some embodiments, the adjustable photovoltaic support device according to embodiments of the present invention further includes a first hoisting wheel and a second hoisting wheel. The first hoisting wheel is rotatably mounted on the first column 11 about a second axis, with one end of the first rope 21 wound around the first hoisting wheel. The second hoisting wheel is rotatably mounted on the second column 12 about a third axis, with the other end of the first rope 21 wound around the second hoisting wheel. The second axis extends perpendicular to the length of the portion of the first rope 21, and the second axis extends in the same direction as the third axis.

[0070] It can be understood that the first winch wheel and the second winch wheel are used to reel in and release the first rope 21 , so that the portion of the first rope 21 connected between the first column 11 and the second column 12 can move in the first direction.

[0071] For example, the first column 11 is located on the left and the second column 12 is located on the right. The first winch wheel reels the first rope 21, and the second winch wheel releases the first rope 21, so that the part of the first rope 21 connected between the first column 11 and the second column 12 moves to the left.

[0072] Similarly, the first winch wheel releases the first rope 21, and the second winch wheel reels the first rope 21, so that the portion of the first rope 21 connected between the first column 11 and the second column 12 moves to the right.

[0073] In some embodiments, the adjustable photovoltaic support device of an embodiment of the present invention also includes a first pulley and a second pulley, the first pulley is arranged on the first column 11, and the second pulley is arranged on the second column 12, the first rope 21 is wound around the first pulley and the second pulley, and one end of the first rope 21 is wound around the first winch wheel, and the other end of the first rope 21 is wound around the second winch wheel.

[0074] In some embodiments, the first rotating member 41 includes a first connecting portion 411 and a second connecting portion 412, the first connecting portion 411 is used to connect to one end of the second rope 22, and the second rotating portion is rotatably provided on the first column 11 around the first axis, and the second rotating member 42 includes a third connecting portion 421 and a fourth connecting portion 422, the third connecting portion 421 is used to connect to the other end of the second rope 22, and the second connecting portion 412 is rotatably provided on the second column 12 around the first axis, so that the first rotating member 41 and the second rotating member 42 rotate around the first axis, driving the second rope 22 to rotate around the first axis.

[0075] Specifically, if Figure 1 As shown, the first rotating member 41 is provided at the upper end of the first column 11 , the second connecting portion 412 is hinged to the first column 11 , the second rotating member 42 is provided at the upper end of the second column 12 , and the fourth connecting portion 422 is hinged to the second column 12 .

[0076] It can be understood that the synchronous rotation of the first rotating member 41 and the second rotating member 42 is that the first rotating member 41 and the second rotating member 42 rotate synchronously around the first axis, so as to drive the second rope 22 to rotate, so that the front end of the photovoltaic panel 6 is higher or lower than the rear end of the photovoltaic panel 6, thereby achieving the adjustment of the light receiving angle of the photovoltaic panel 6.

[0077] In some embodiments, the first rotating member 41 also includes a fifth connecting portion 413, the first rotating member 41 is triangular in shape, and the three top angles of the first rotating member 41 respectively form a first connecting portion 411, a second connecting portion 412 and a fifth connecting portion 413, the second rotating member 42 also includes a sixth connecting portion 423, the second rotating member 42 is triangular in shape, and the three top angles of the second rotating member 42 respectively form a third connecting portion 421, a fourth connecting portion 422 and a sixth connecting portion 423.

[0078] Specifically, if Figure 6 As shown, the first rotating member 41 and the second rotating member 42 are shaped as congruent triangles to ensure the rotation angle when the rotating assembly 4 drives the second connecting member to rotate.

[0079] Preferably, the first and second rotating members 41, 42 are shaped like isosceles triangles. It should be noted that the top corners of the first rotating member 41 form the second connecting portion 412, while the bottom corners of the first rotating member 41 respectively form the first connecting portion 411 and the fifth connecting portion 413. In other words, rotating the fifth connecting portion 413 about the second axis, i.e., rotating the first rotating member 41 about the second axis, can drive the second connecting member to rotate. Similarly, the top corners of the second rotating member 42 form the fourth connecting portion 422, while the bottom corners of the second rotating member 42 respectively form the third connecting portion 421 and the sixth connecting portion 423.

[0080] In some embodiments, the adjustable photovoltaic support device of an embodiment of the present invention also includes a control component 52, the control component 52 includes at least one driving member, the driving member has a driving part, and the driving part is used to connect with the fifth connecting part 413 and the sixth connecting part 423 so as to drive the fifth connecting part 413 and the sixth connecting part 423 to rotate around the second axis.

[0081] For example, when there is a driving member, the fifth connecting portion 413 and the sixth connecting portion 423 are both connected to the driving portion of the driving member through a rope, and the rotation angles of the fifth connecting portion 413 and the sixth connecting portion 423 are kept consistent when they rotate. Figure 1 As shown, when the driving member is started, the rope is tightened, and the first rotating member 41 and the second rotating member 42 rotate simultaneously in the same direction around the first axis, driving the second rope 22 to rotate, so that the front end of the photovoltaic panel 6 is higher than the rear end of the photovoltaic panel 6, thereby adjusting the light receiving angle of the photovoltaic panel 6.

[0082] It can be understood that when the second rope 22 changes its vertical position, the first rope 21 will deform and tend to return to its initial position. Therefore, when the second driving member is turned off, the rope is released, and the first rope 21 gradually returns to its initial position. This, in turn, drives the second connecting member to return to its initial position via the photovoltaic panel 6, thus facilitating the next angle adjustment.

[0083] For example, if there are two driving members, the output portions of the two driving members are connected to the fifth connecting portion 413 and the sixth connecting portion 423 respectively via ropes, and the direction and magnitude of the ropes applied to the fifth connecting portion 413 and the sixth connecting portion 423 are equal. When the driving members are activated or deactivated simultaneously, the first rotating member 41 and the second rotating member 42 can be controlled to rotate simultaneously to adjust the light receiving angle of the photovoltaic panel 6.

[0084] It should be noted that the driving member may be a motor. Of course, the driving member may also be a structure with a self-locking function, such as a ratchet and pawl structure.

[0085] For example, the driving member comprises a ratchet and pawl structure, wherein the ratchet forms the driving portion, which is connected to the fifth connecting portion 413 and the sixth connecting portion 423 via a rope. The driving portion is rotatable in one direction but not rotatable in the other direction, i.e., it is locked. After the driving portion has rotated a certain angle, it can cooperate with the pawl to lock the rotation of the driving portion. In other words, the driving portion is rotated, and the fifth connecting portion and the sixth connecting portion 423 are driven to rotate via the rope, thereby moving the second rope 22 to achieve angular adjustment of the photovoltaic panel 6 in the second direction.

[0086] In some embodiments, the adjustable photovoltaic support device of the embodiment of the present invention also includes a fixing member 71, and there are multiple fixing members 71.
