Description

Technical Field

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

[0002] The flexible photovoltaic support system is a large-span, high-clearance, multi-span structure. The structure uses prestressed steel wire ropes to be tensioned between the two fixed points. The two fixed points use rigid structures and external inclined steel strands to provide support reaction forces. It can adapt to conditions such as mountain undulations and increased vegetation. It only needs to set up the foundation at a suitable location and tension the prestressed steel strands or wire ropes. Under the condition that the water level remains unchanged, the construction of rigid columns, foundations and flexible supports can be realized in lakes and fish ponds.

[0003] The photovoltaic panel is fixed on the steel wire rope through a fixed bracket on the flexible photovoltaic bracket. The currently common fixed bracket is in an inverted H-shape. The frame of the photovoltaic panel is located in the fixed bracket and is fastened by bolts. The arc-shaped buckle is fastened to the steel wire rope through bolts and nuts at the bottom of the fixed bracket. In this way, the fixed bracket can be fixed to achieve the installation of the photovoltaic panel.

[0004] The installation method of the photovoltaic panel and the fixed bracket in the above-mentioned method is cumbersome. First, the fixed bracket is connected to the photovoltaic panel by bolts, and then the fixed bracket is fixed to the steel wire rope by bolts. Some photovoltaic panels are installed at a high height, which is very inconvenient for tightening the bolts, increasing the installation difficulty for the installer; for this reason, the present application proposes a photovoltaic flexible bracket. Summary of the invention

[0008] A fixing bracket capable of fixing the installation frame and the photovoltaic panel on the steel strand is used in conjunction with the installation frame; the fixing bracket comprises a first fixing block and a second fixing block distributed up and down, the first fixing block and the second fixing block are fixed with a rectangular frame, the installation frame slides against the first fixing block and the second fixing block, two guide bars used in conjunction with the bayonet are fixed to the bottom of the first fixing block, a first rectangular rod with a movable arrangement is provided through the rectangular frame, a vertical rod with a rotatable arrangement and capable of being connected to the first rectangular rod is provided through the rectangular frame and the second fixing block, a U-shaped block is fixedly connected to the bottom of the second fixing block, two second rectangular rods with a sliding arrangement are provided through the bottom of the U-shaped block, a clamping mechanism capable of being fixed on the steel strand is provided between the second rectangular rod and the U-shaped block, a wedge-shaped groove is provided through the second rectangular rod, two wedge-shaped blocks connected to the vertical rod are slidably connected to the U-shaped block, the wedge block is slidably connected in the wedge-shaped groove, a movably arranged locking rod is installed on the second rectangular rod, the installation frame abuts against the first rectangular rod and squeezes it until the installation frame abuts against the rectangular frame, and the locking rod can lock the installation frame in the fixing bracket.

[0009] Preferably, a collar is fixedly connected to the first rectangular rod, a first spring is fixedly connected to the collar, the other end of the first spring is fixedly connected to the inner wall of the rectangular frame, and the first spring is sleeved on the outside of the first rectangular rod.

[0010] Preferably, the upper end of the vertical rod is fixedly connected to a first circular plate, the upper end of the first circular plate is eccentrically hingedly connected to a first connecting rod, and the first connecting rod is hingedly connected to the bottom of the first rectangular rod.

[0011] Preferably, the clamping mechanism comprises a first arc-shaped clamping block, to which two connecting blocks are fixedly connected, the connecting block is fixedly connected to the bottom of the second rectangular rod, and the bottom of the U-shaped block is fixedly connected to the second arc-shaped clamping block.

[0012] Preferably, a positioning block is fixedly connected to the inner bottom of the U-shaped block, a guide rod is provided on the positioning block, a guide groove is fixedly connected to the wedge-shaped block, and the guide rod is slidably connected in the guide groove.

[0013] Preferably, a second circular plate is fixedly connected to the bottom of the vertical rod, a second connecting rod is eccentrically hingedly connected to the bottom of the second circular plate, and the second connecting rod is hingedly connected to the upper end of the wedge block.

[0014] Preferably, a rectangular groove is provided at the upper end of the second rectangular rod, the locking rod is slidably connected in the rectangular groove, a second spring is fixedly connected to the bottom of the locking rod, and the lower end of the second spring is fixedly connected to the inner bottom of the rectangular groove.

[0015] Preferably, a rectangular through slot is penetrated through the second fixing block, and the locking rod is a rectangular rod, and the locking rod penetrates the rectangular through slot and is slidably disposed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Rotate the vertical rod, and the rotation of the vertical rod drives the second circular plate to rotate, so as to realize the movement of the wedge block.

[0018] 2. The first arc-shaped clamping block can be installed on the U-shaped block but not against the steel strand, so that the subsequent fixed bracket can be moved, and the fixed bracket can be initially installed on the steel strand.

[0019] 3. The second rectangular rod moves, but the lock hole is not opposite to the lock rod. At this time, the lock rod and the rectangular groove move relative to each other, and the second spring is compressed. As the fixed bracket moves, when the lock rod is opposite to the lock hole, the lock rod is moved up and reset and snapped into the lock hole under the action of the second spring, so that the fixed bracket can be fixedly connected to the installation frames on both sides.

[0020] 4. The second rectangular rod moves upward to drive the connecting block and the first arc-shaped clamping block to move upward. Finally, the first arc-shaped clamping block abuts against the steel strand. The fixing bracket can be fixed on the steel strand through the first arc-shaped clamping block and the second arc-shaped clamping block.

[0021] 5. Since the installation frame is locked by the locking rod and cannot move, the first rectangular rod cannot move, which in turn feeds back to the wedge block and the first arc-shaped clamping block, so that the fixed bracket, the steel strand and the installation frame are in a locked state to ensure the stability of the installation frame after installation. Even if the installation frame and the photovoltaic panel vibrate due to wind and rain, the bolts will not loosen.

[0022] To sum up, during the installation process of the present invention, it is only necessary to manually rotate the vertical rod and install the second arc-shaped clamping block, and then install the installation frame on the fixed bracket and push the installation frame until it cannot be moved, so that the photovoltaic panel can be fixed on the steel wire rope. The disadvantages of the existing installation through bolts and nuts that are cumbersome and require the use of tools are avoided, the installation difficulty of the installer is reduced, and at the same time the stability of the entire device after installation can be ensured.

[0038] A wedge-shaped groove 15 penetrates the second rectangular rod 12, two wedge-shaped blocks 19 connected to the vertical rod 16 are slidably connected to the U-shaped block 11, a positioning block 20 is fixedly connected to the inner bottom of the U-shaped block 11, and a guide rod 27 is provided on the positioning block 20, a guide groove 26 is fixedly connected to the wedge block 19, and the guide rod 27 is slidably connected in the guide groove 26 to ensure stable sliding of the wedge block 19; a second circular plate 17 is fixedly connected to the bottom of the vertical rod 16, and a second connecting rod 18 is eccentrically hingedly connected to the bottom of the second circular plate 17, and the second connecting rod 18 is hingedly connected to the upper end of the wedge block 19.

[0039] The wedge block 19 is slidably connected in the wedge groove 15, and a movably arranged locking rod 13 is installed on the second rectangular rod 12. A rectangular groove 28 is provided at the upper end of the second rectangular rod 12, and the locking rod 13 is slidably connected in the rectangular groove 28. A second spring 29 is fixedly connected to the bottom of the locking rod 13, and the lower end of the second spring 29 is fixedly connected to the inner bottom of the rectangular groove 28. A rectangular through groove is penetrated on the second fixed block 10, and the locking rod 13 is a rectangular rod, and the locking rod 13 is slidably arranged through the rectangular through groove.

[0040] The installation frame 1 abuts against the first rectangular rod 23 and squeezes it until the installation frame 1 abuts against the rectangular frame 8, and the locking rod 13 can lock the installation frame 1 in the fixing bracket.

[0041] When the present invention is used, firstly, the fixing bracket is installed on the steel strand, and the specific operation is as follows:

[0042] The installer manually rotates the vertical rod 16, and the rotation of the vertical rod 16 drives the second circular plate 17 to rotate. Under the action of the second connecting rod 18, the wedge block 19 moves. Under the cooperation of the guide rod 27 and the guide groove 26, the wedge block 19 can be stably moved, so that the wedge block 19 is not directly opposite to the second rectangular rod 12. Then the installer holds the first arc-shaped clamping block 6 to make the second rectangular rod 12 pass through the groove body, and then loosens the vertical rod 16.

[0043] The rotation of the vertical rod 16 drives the first circular plate 9 to rotate, and the rotation of the first circular plate 9 drives the first connecting rod 22 to rotate, thereby driving the first rectangular rod 23 to move. At this time, the first spring 25 is compressed. Therefore, when the installer loosens the vertical rod 16, under the action of the first spring 25, the first connecting rod 22, the first rectangular rod 23, the first circular plate 9 and the vertical rod 16 are reset, and then the second circular plate 17, the second connecting rod 18 and the wedge block 19 are reset. Finally, the wedge block 19 is slidably inserted into the wedge groove 15, so that the second rectangular rod 12 can be reset, so that the first arc clamping block 6 can be installed on the U-shaped block 11 but not against the steel strand, so that the subsequent fixed bracket can be moved, and the fixed bracket can be initially installed on the steel strand so that it will not fall off the steel strand;

[0044] As described above, the fixing bracket can be installed on the steel strand. It should be noted that the first rectangular rod 23 faces the direction of the photovoltaic panel 2 that has been fixed;

[0045] The installation frame 1 and the photovoltaic panel 2 are installed. The installer buckles the bayonet 3 on the installation frame 1 on the guide bar 7, pushes the installation frame 1 to move, and the movement of the installation frame 1 drives the fixing bracket to move. Finally, the first fixing block 4 and the second fixing block 10 on the fixing bracket are buckled on the fixed installation frame 1. At this time, the first rectangular rod 23 is against the installation frame 1. The installer continues to push the installation frame 1 to move. At this time, the installation frame 1 on the other side of the first rectangular rod 23 is squeezed and moved. Under the resistance of the first spring 25, the installation frame 1 to be fixed is against the rectangular frame 8. At this time, the locking rod 13 is opposite to the locking hole 5.

[0046] The movement of the first rectangular rod 23 drives the movement of the first connecting rod 22, the movement of the first connecting rod 22 drives the first circular plate 9 to rotate, the rotation of the first circular plate 9 drives the vertical rod 16 to rotate, the rotation of the vertical rod 16 drives the second circular plate 17 to rotate, thereby driving the two second connecting rods 18 to rotate, the rotation of the second connecting rod 18 drives the wedge block 19 to move, the movement of the wedge block 19 cooperates with the wedge groove 15 to realize the upward movement of the two second rectangular rods 12, the upward movement of the second rectangular rod 12 drives the connecting block 14 and the first arc-shaped clamping block 6 to move upward, and finally the installation frame 1 on the other side abuts against the rectangular frame 8;

[0047] The movement of the second rectangular rod 12 drives the second spring 29 and the locking rod 13 to move upward. The locking rod 13 first moves upward and abuts against the bottom of the installation frame 1. However, as the second rectangular rod 12 moves, the locking hole 5 is not opposite to the locking rod 13. At this time, the locking rod 13 and the rectangular groove 28 move relative to each other, and the second spring 29 is compressed. As the fixed bracket moves, when the locking rod 13 is opposite to the locking hole 5, the locking rod 13 is moved upward and reset and stuck into the locking hole 5 under the action of the second spring 29, so that the fixed bracket can be fixedly connected to the installation frames 1 on both sides.

[0048] The second rectangular rod 12 moves upward to drive the connecting block 14 and the first arc-shaped clamping block 6 to move upward. Finally, the first arc-shaped clamping block 6 abuts against the steel strand. The fixing bracket can be fixed on the steel strand through the first arc-shaped clamping block 6 and the second arc-shaped clamping block 21.

[0049] Since the installation frame 1 is locked by the locking rod 13 and cannot move, the first rectangular rod 23 cannot move, and then feedback is given to the wedge block 19 and the first arc-shaped clamping block 6, so that the fixing bracket is locked with the steel strand and the installation frame 1, so as to ensure the stability of the installation frame 1 after installation, and the bolts will not loosen even if the installation frame 1 and the photovoltaic panel 2 vibrate due to wind and rain;

[0050] Repeat the above operation to install the installation frame 1 and the photovoltaic panel 2 one by one on the steel strand;

[0051] During the installation process, it is only necessary to manually rotate the vertical rod 16 and install the second arc-shaped clamping block 6, and then install the installation frame 1 on the fixed bracket and push the installation frame 1 until it cannot be moved to fix the photovoltaic panel 2 on the steel strand. This avoids the disadvantages of the existing installation method using bolts and nuts, which is cumbersome and requires the use of tools, reduces the installation difficulty for installers, and can ensure the stability of the entire device after installation.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
