Description

Technical Field

[0001] The invention relates to the technical field of photovoltaics, and in particular to a rotating flexible photovoltaic bracket. Background Art

[0002] Flexible photovoltaic support is to replace the purlins in traditional rigid support technology with steel strands, that is, photovoltaic modules are installed on rows of steel strands. The steel strands use the first line method to provide pre-tensioning force. The two ends of the steel strands are connected by rigid supports, which can achieve a maximum spacing of 10-30m. Sliders are set at both ends of the steel strands, and the angle of the photovoltaic module is changed by sliding the sliders up and down to achieve solar tracking of the photovoltaic module. As the two sliders at the end of the steel strand rise or fall, the position between the two sliders changes, resulting in a change in the length of the steel strand required between the two sliders. Since it is difficult to adjust the length of the steel strand between the two sliders, it is inconvenient to adjust the angle of the photovoltaic panel. Summary of the invention

[0038] 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.

[0039] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0040] like Figures 1 to 7 As shown, the rotating flexible photovoltaic support 100 of the embodiment of the present invention includes a column 1, a first connector 2 and a lifting assembly 4. The column 1 includes a threaded section 105, and the threaded section 105 is provided with an internal thread. There are multiple columns 1, and the multiple columns 1 include a first group of columns and a second group of columns. The first group of columns includes a first column 101 and a second column 102 arranged at intervals along a first direction, and the second group of columns includes a third column 103 and a fourth column 104 arranged at intervals along the first direction. The first group of columns and the second group of columns are arranged along the second direction, the first direction is orthogonal to the up-down direction, the second direction is orthogonal to the up-down direction, and the first direction and the second direction form an angle.

[0041] At least one first connection member 2 is connected between the first column 101 and the fourth column 104, at least one first connection member 2 is connected between the second column 102 and the third column 103, and the first connection member 2 between the first column 101 and the fourth column 104 is cross-arranged with the first connection member 2 between the second column 102 and the third column 103. There are multiple lifting assemblies 4, and the multiple lifting assemblies 4 correspond to the multiple columns 1 one by one. The lifting assemblies 4 are connected to the corresponding columns 1 and are adjustable in the up and down directions relative to the columns 1.

[0042] The lifting assembly 4 includes a lifting rod 402, the lower end of which extends into the column 1. The lifting rod 402 has an external thread that matches the internal thread, so that the lifting rod 402 can move in the up and down directions along the column 1 under the action of the thread transmission. The lifting rod 402 has a spiral groove 4021, which is circumferentially arranged around the lifting rod 402. The spiral groove 4021 is opposite to the rotation direction of the external thread. The first connecting member 2 is connected to the column 1 through the lifting rod 402 and at least a portion of the first connecting member 2 is wound in the spiral groove 4021.

[0043] When the lifting rod 402 moves in the up and down direction, the spiral groove 4021 is used to drive the first connecting member 2 to extend and retract, so as to adjust the length of the first connecting member 2 between the two spiral grooves 4021 .

[0044] In order to make the technical solution of the present application easier to understand, the technical solution of the present application is further described below by taking the first direction being consistent with the east-west direction and the second direction being consistent with the north-south direction as an example, wherein the east-west direction and the north-south direction are as follows: Figure 1 shown.

[0045] For example, Figure 1 As shown, the first column 101 is located on the west side of the second column 102, the third column 103 is located on the west side of the fourth column 104, the first group of columns is located on the north side of the second group of columns, the first group of columns is located on the north side of the second group of columns, the first column 101 and the third column 103 correspond to each other in the north-south direction, and the second column 102 and the fourth column 104 correspond to each other in the north-south direction. The highest position and the lowest position of the lifting assembly 4 on each column 1 are the same. It can be understood that the photovoltaic panel 7 of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention in the initial state (for example, 7:00 in the morning) presents a posture of high in the west and low in the east, that is, at this time, the second column 102 and the fourth column 104 are at the lowest point, and the first column 101 and the third column 103 are at the highest point. Of course, the photovoltaic panel 7 of the rotating flexible photovoltaic bracket 100 in the final state (for example, 19:00 in the afternoon) of the embodiment of the present invention is in an east-high and west-high posture, that is, at this time, the second column 102 and the fourth column 104 are at the highest point, and the first column 101 and the third column 103 are at the lowest point.

[0046] The initial length of the first connecting member 2 is the straight-line distance between the lifting assembly 4 on the first column 101 when it is at the highest point and the lifting assembly 4 on the fourth column 104 when it is at the lowest point, plus the straight-line distance between the highest point and the lowest point of the lifting assembly 4 on the first column 101, plus the length of the two ends of the first connecting member 4 connected to the first column 101 and the fourth column 104 through the corresponding spiral grooves 4021.

[0047] like Figure 3As shown, when the lifting rod 402 rotates forward, the lifting rod 402 moves upward under the action of the spiral transmission, and the first connecting member 2 extends from the upper end of the spiral groove 4021 and extends from the lower end of the spiral groove 4021 under the action of the spiral groove 4021. When the lifting rod 402 rotates reversely, the lifting rod 402 moves downward under the action of the spiral transmission, and the first connecting member 2 extends from the lower end of the spiral groove 4021 and extends from the upper end of the spiral groove 4021 under the action of the spiral groove 4021.

[0048] When the rotating flexible photovoltaic bracket 100 of the embodiment of the invention is in use, for example, at 12:00 noon when the sun is in the south, it is necessary to change the photovoltaic panel 7 from the tilted posture of high in the west and low in the east to high in the north and low in the south (such as Figure 1 The lifting assembly 4 on the second column 102 is controlled to rise and the lifting assembly 4 on the third column 103 is controlled to descend at the same speed as the lifting assembly 4 on the second column 102, so that the lifting assembly 4 on the second column 102 rises to the same height as the lifting assembly 4 on the first column 101, and the lifting assembly 4 on the third column 103 descends to the same height as the lifting assembly 4 on the fourth column 104, thereby making the photovoltaic panel 7 present a posture of high in the north and low in the south. When the lifting assembly 4 on the second column 102 is ascending, the spiral groove 4021 on the second column 102 drives the length of the first connecting member 2 between the top of the second column 102 and the spiral groove 4021 on the second column 102 to extend, and when the lifting assembly 4 on the third column 103 is descending, the spiral groove 4021 on the third column 103 drives the length of the first connecting member 2 between the top of the third column 103 and the spiral groove 4021 on the third column 103 to shorten, so as to compensate for the distance change caused by the relative position change between the spiral groove 4021 on the second column 102 and the spiral groove 4021 on the third column 103. Figure 5 As shown, the first connecting member 2 connected between the second column 102 and the third column 103 changes from the inclined state shown by the dotted line to the inclined state shown by the solid line. As a result, the length difference of the first connecting member 2 generated by the movement of the lifting assembly 4 in the up and down directions forms an equal triangle. The upper and lower lengths of the first connecting member 2 on the second column 102 and the third column 103 complement each other, so that the photovoltaic panel 7 presents a posture of high in the north and low in the south.

[0049] For example, at 16:00 in the afternoon when the sun is in the west, the photovoltaic panel 7 needs to be tilted from high in the north to low in the south (such as Figure 1At the same time, the lifting assembly 4 on the fourth column 104 is controlled to rise and the lifting assembly 4 on the first column 101 is controlled to descend at the same speed as the lifting assembly 4 on the fourth column 104, so that the lifting assembly 4 on the fourth column 104 rises to the same height as the lifting assembly 4 on the second column 102, and the lifting assembly 4 on the first column 101 descends to the same height as the lifting assembly 4 on the third column 103, thereby making the photovoltaic panel 7 present a posture of high in the north and low in the south. Among them, when the lifting assembly 4 on the fourth column 104 is in the process of ascending, the spiral groove 4021 on the fourth column 104 drives the length of the first connecting member 2 between the top end of the fourth column 104 and the spiral groove 4021 on the fourth column 104 to shorten, and when the lifting assembly 4 on the first column 101 is in the process of descending, the spiral groove 4021 on the first column 101 drives the length of the first connecting member 2 between the top end of the first column 101 and the spiral groove 4021 on the first column 101 to extend, so as to compensate for the distance change caused by the relative position change between the spiral groove 4021 on the fourth column 104 and the spiral groove 4021 on the first column 101.

[0050] Therefore, the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention sets a spiral groove 4021 on the lifting rod 402. When the position of the spiral groove 4021 connecting the two ends of the first connecting member 2 changes relatively, the spiral groove 4021 drives the first connecting member 2 to extend and retract to adjust the distance change caused by the relative position change of the spiral groove 4021 at both ends of the first connecting member 2, thereby facilitating the adjustment of the photovoltaic panel 7 of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention.

[0051] Therefore, the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention has the advantages of convenient angle adjustment of the photovoltaic panel 7 and the like.

[0052] Optionally, the connecting member is a steel strand.

[0053] In some embodiments, the lifting assembly 4 further includes a first rotating shaft 4011 , which is used to support the first connecting member 2 extending from the upper end of the spiral groove 4021 , so that the first connecting member 2 can spirally rotate in the spiral groove 4021 .

[0054] For example, Figure 3 As shown, the axis of the first rotating shaft 4011 is arranged along the north-south direction, and the first rotating shaft 4011 is arranged at the upper end position adjacent to the spiral groove 4021. The first connecting member 2 is wound around the first rotating shaft 4011 so that the first connecting member 2 can extend into or out from the upper end of the spiral groove 4021.

[0055] Therefore, by providing the first rotating shaft 4011, it is beneficial for the first connecting member 2 to extend into or out from the upper end of the spiral groove 4021, which is beneficial to improving the operating reliability of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention.

[0056] In some embodiments, the lifting assembly 4 also includes a second rotating shaft 4012, which is spaced apart from the first rotating shaft 4011 in the up and down directions, and the second rotating shaft 4012 is used to support the first connecting member 2 extending from the lower end of the spiral groove 4021 so that the first connecting member 2 can rotate spirally in the spiral groove 4021.

[0057] For example, Figure 3 As shown, the axis of the second rotating shaft 4012 is arranged along the north-south direction, and the second rotating shaft 4012 is arranged at the lower end position adjacent to the spiral groove 4021. The first connecting member 2 is wound around the second rotating shaft 4012 so that the first connecting member 2 can extend into or out from the lower end of the spiral groove 4021.

[0058] Therefore, by providing the second rotating shaft 4012, it is helpful for the first connecting member 2 to extend into or out from the lower end of the spiral groove 4021, which is helpful to improve the operating reliability of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention.

[0059] In some embodiments, the lifting assembly 4 further includes a support frame 4013 , which is rotatably connected to the lifting rod 402 around the axis of the lifting rod 402 , and each of the first rotating shaft 4011 and the second rotating shaft 4012 is connected to the support frame 4013 .

[0060] For example, Figure 3 As shown, the support frame 4013 has a first part and a second part connected to each other, the first part is cylindrical and sleeved on the lifting rod 402, and can rotate around the axis of the lifting rod 402. The first rotating shaft 4011 and the second rotating shaft 4012 are rotatably arranged on the second part, so that the first rotating shaft 4011 and the second rotating shaft 4012 support the first connecting member 2.

[0061] Therefore, the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention is rotatably connected to the lifting rod 402 by setting a support member to facilitate the installation of the first rotating shaft 4011 and the second rotating shaft 4012, thereby making the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention simple in structure.

[0062] In some embodiments, the rotating flexible photovoltaic bracket 100 also includes at least two mutually parallel second connecting members 3, one end of the second connecting member 3 is connected to at least one first connecting member 2, and the other end of the second connecting member 3 is connected to at least one first connecting member 2, and the second connecting member 3 is used to install the photovoltaic panel 7.

[0063] For example, Figure 1 and Figure 2 As shown, the second connector 3 includes two, and the two second connectors 3 are evenly spaced in the north-south direction, and the length direction of the two second connectors 3 is parallel to the east-west direction. One end of the second connector 3 on the north side is connected to one end of a first connector 2, and the other end of the second connector 3 on the north side is connected to one end of another first connector 2, one end of the second connector 3 on the south side is connected to the other end of a first connector 2, and the other end of the second connector 3 on the south side is connected to the other end of another first connector 2. The photovoltaic panel 7 is installed on the two second connectors 3 parallel to each other.

[0064] Therefore, the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention can prevent the photovoltaic panel 7 from affecting the extension and retraction of the first connecting member 2 due to being installed on the first connecting member 2 by setting two at least two mutually parallel second connecting members 3 for installing the photovoltaic panel 7, thereby improving the operating reliability of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention.

[0065] Alternatively, if Figure 5 As shown, the second connecting member 3 is a connecting rod, and both ends of the second connecting member 3 are respectively provided with slide rails 301 extending along the length thereof, and the slide rails 301 are provided with sliders 302 cooperating with the slide rails 301, and the sliders 302 can slide along the extension direction of the slide rails 301, and the sliders 302 are provided with through holes 303, and the second connecting member 3 is connected to the first connecting member through the through holes 303.

[0066] A first slide rail is provided at the west end of the second connecting member 3, and the first slide rail extends in the east-west direction. A first slider is provided on the first slide rail, and the first slider can slide movably with the first slide rail in the east-west direction. The first slider is provided with a first through hole arranged in the north-south direction, and the first connecting member 2 passes through the first through hole.

[0067] A second slide rail is provided at the east end of the second connecting member 3. The second slide rail extends in the east-west direction. A second slider is provided on the second slide rail. The second slider can slide movably with the second slide rail in the east-west direction. The second slider is provided with a second through hole arranged in the north-south direction.

[0068] Specifically, when the second connecting member 3 is connected to the first connecting member 2, for example, Figure 1As shown, the first connecting member 2 connected between the first column 101 and the fourth column 104 is penetrated through the first through hole on the first slider at the west end of the second connecting member 3 on the north side, and the first connecting member 2 connected between the second column 102 and the third column 103 is penetrated through the second through hole on the second slider at the east end of the second connecting member 3 on the north side, thereby completing the installation of the second connecting member 3 on the north side. The first connecting member 2 connected between the second column 102 and the third column 103 is penetrated through the first through hole on the first slider at the west end of the second connecting member 3 on the south side, and the first connecting member 2 connected between the first column 101 and the fourth column 104 is penetrated through the second through hole on the second slider at the east end of the second connecting member 3 on the south side, thereby completing the installation of the second connecting member 3 on the south side.

[0069] When using, Figure 6 and Figure 7 As shown, when the intersection angle between the two first connecting members 2 changes, the first slider and the second slider at the east and west ends of the second connecting member 3 slide in the east-west direction to compensate for the displacement change of the two first connecting members 2 caused by the change in the intersection angle, thereby facilitating the adjustment of the first connecting member 2, and further facilitating the adjustment of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention.

[0070] In some embodiments, the rotating flexible photovoltaic support 100 further includes a driving member 501 , which is connected to the column 1 , and is used to drive the lifting rod 402 to rotate.

[0071] For example, the driving member 501 is a driving motor, which is mounted on the column 1 and connected to the lifting rod 402 to drive the lifting rod 402 to rotate.

[0072] Therefore, by providing the driving member 501 to drive the lifting rod 402 to rotate, the lifting rod 402 can be easily rotated, thereby further facilitating the adjustment of the rotating flexible photovoltaic support 100 according to the embodiment of the present invention.

[0073] Optionally, the rotating flexible photovoltaic support 100 of the embodiment of the present invention further includes a PLC control system, which is electrically connected to the driving member 501 , and the PLC control system controls the rotation of the lifting member 402 by controlling the driving member 501 .

[0074] By setting up a PLC control system, it is convenient to control the lifting speed of the lifting assembly 4, so as to facilitate the lifting speed of the lifting assembly 4 connected at both ends of the first connecting member 2, thereby facilitating the adjustment of the angle of the photovoltaic panel 7, thereby improving the operating reliability of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention.

[0075] In some embodiments, the rotating flexible photovoltaic bracket 100 also includes an active member 502 and a driven member 503, the active member 502 is arranged on the column 1, the driving member 501 is connected to the active member 502, and the driven member 503 is connected to the lifting rod 402, and the active member 502 cooperates with the driven member 503 so that the driving member 501 drives the lifting rod 402 to rotate.

[0076] By providing the active member 502 and the driven member 503 , it is advantageous for the driving member 501 to drive the lifting rod 402 to rotate, thereby further facilitating the adjustment of the rotating flexible photovoltaic support 100 according to the embodiment of the present invention.

[0077] Optionally, the active member 502 is a first gear 601 , the driven member 503 is a second gear 602 , the first gear 601 is meshed with the second gear 602 , and the length of the second gear 602 in its extending direction is greater than the length of the first gear 601 in its extending direction.

[0078] For example, Figure 3 As shown, the first gear 601 is mounted on the output shaft of the driving motor. When the driving motor rotates forward, it drives the first gear 601 to rotate forward, the first gear 601 drives the second gear 602 to rotate forward, and the second gear 602 drives the lifting rod 402 to rotate forward. When the lifting rod 402 rotates forward, it moves upward under the action of the screw transmission. That is to say, the second gear 602 moves upward while rotating under the drive of the lifting rod 402. Since the length of the second gear 602 in the vertical direction is greater than the length of the first gear 601 in the vertical direction, the first gear 601 and the second gear 602 are always in a meshing state.

[0079] Therefore, the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention is beneficial to improving the transmission smoothness between the active component 502 and the driven component 503 by setting the active component 502 and the driven component 503 in the form of a gear pair transmission, which is beneficial to improving the working reliability of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention.

[0080] Optionally, the rotating flexible photovoltaic support 100 further includes a reducer 504 , and the driving member 501 and the first gear 601 are connected via the reducer 504 .

[0081] By setting a reducer 504 between the drive motor and the first gear 601, the rotation speed of the lifting rod 402 can be better controlled, which is beneficial to controlling the rotation speed of the lifting rod 402 and is beneficial to further facilitate the adjustment of the rotating flexible photovoltaic bracket 100 of the embodiment of the present invention.
