Description

Technical Field

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

[0002] Photovoltaic bracket connectors are an indispensable part of the photovoltaic system. Their main function is to tightly connect photovoltaic components, commonly known as photovoltaic panels, to photovoltaic brackets. Photovoltaic bracket connectors are located between photovoltaic panels and brackets. They are responsible for fixing photovoltaic panels on the brackets to ensure that photovoltaic panels will not move or tilt under the action of wind or other external forces. These connectors must not only ensure the stability of the connection, but also take into account the convenience of installation and disassembly, so that they can be easily operated when maintenance or replacement of photovoltaic panels is required.

[0003] The angle of the photovoltaic bracket needs to be changed according to different terrains. This is mainly to ensure that the photovoltaic modules can receive solar radiation to the greatest extent, thereby improving the efficiency of photovoltaic power generation. However, when adjusting the angle of the photovoltaic bracket, the mounting plate on which the photovoltaic panel is installed needs to be removed, which makes installation and debugging troublesome, and it cannot be guaranteed that each universal angle maintains a consistent angle, requiring multiple debugging.

The two ends of a connecting rod 23 are connected to the connecting seat 5 for limited rotation. A first gear 24 is provided in the middle part of the first connecting rod 23; a transmission belt 27 is meshed and connected to the first gear 24 and the second gear 26; a screw rod 35 is provided in the second universal angle 21, and a fixing screw block 36 is threadedly connected to the upper end of the screw rod 35, and a thin rod 37 is provided below the screw rod 35. A fixing block 39 is provided in the second universal angle 21, and the bottom end of the thin rod 37 passes through the fixing block 39. A third spring 38 is provided between the fixing block 39 and the fixing screw block 36, and the third spring 38 is sleeved on the thin rod 37; a pull rope 40 is provided at the bottom of the thin rod 37, and an open tube 41 is provided in the second universal angle 21, and a slider 42 is slidably connected to the open tube 41, and the other end of the pull rope 40 is fixedly connected to the slider 42.

[0033] In the present invention, the first base 1 and the second base 3 are first installed on the ground surface, and then the heights of the first extension rod 2 and the second extension rod 4 are adjusted;

[0034] The isolation plate 22 is plugged or threadedly connected to the first universal angle 16 and the second universal angle 21 after the first universal angle 16 and the second universal angle 21 have been adjusted in angle;

[0035] When adjusting the angle of the first universal angle 16 and the second universal angle 21, first insert a wrench matching the pipe mouth of the open tube 41 into the open tube 41. During insertion, the wrench pushes the slider 42 to move into the open tube 41, and the slider 42 pulls the pull rope 40. The pull rope 40 compresses the third spring 38 downward. The third spring 38 pulls the screw rod 35 downward, and the screw rod 35 moves to the bottom of the first support rod 14. Then the wrench is rotated to drive the first connecting rod 23 to rotate, and the first gear 24 rotates accordingly. The first gear 24 drives the transmission belt 27 to rotate. The transmission belt 27 can be a chain, etc. The transmission belt 27 drives the second gear 26 to rotate. The second gear 26 drives the first universal angle 16 to rotate through the second connecting rod 25, so that the first universal angle 16 and the second universal angle 21 rotate synchronously and at the same speed, ensuring that each adjustment maintains a consistent angle, and the photovoltaic panel angle adjustment can be completed without multiple debugging.

[0036] In one embodiment, the screw rod 35 moves to the bottom of the first support rod 14. At this time, only one end of the first support rod 14 is fixed. The first universal angle 16 and the second universal angle 21 can drive the first support rod 14 to rotate. The wrench is disengaged from the open tube 41, and the compressed third spring 38 is reset. The screw rod 35 moves to the top of the first support rod 14 (and passes through the first support rod 14). At this time, both ends of the first support rod 14 are fixed, and the first gear 24 completes self-locking.

[0037] Reference Figure 1-Figure 9 A first opening 6 is provided on the first base 1 and the second base 3, a second opening 12 is provided on the first extension rod 2 and the second extension rod 4, fixing bolts 7 are provided in the first opening 6 and the second opening 12, and a gasket 8 and a fixing nut 9 are provided at the other end of the fixing bolt 7 respectively; an auxiliary frame 10 is provided on the second base 3, the auxiliary frame 10 is liftable, and an auxiliary opening 11 is provided on the auxiliary frame 10, and the auxiliary opening 11 is aligned with the opening tube 41.

[0038] In the present invention, when the first opening 6 and the second opening 12 are aligned, the first extension rod 2 and the second extension rod 4 on the first base 1 and the second base 3 can be fixed by the fixing bolt 7, the gasket 8 and the fixing nut 9;

[0039] The auxiliary frame 10 is liftable and follows the height change of the second extension rod 4. When inserting the wrench, it is inserted through the auxiliary opening 11 on the auxiliary frame 10, which makes it convenient for the staff to insert the wrench.

[0040] Reference Figure 1-Figure 9A protrusion 17 is provided on the upper surface of the first universal angle 16, a groove 18 matching the protrusion 17 is provided on the first support rod 14, an upper cover plate 19 is provided above the groove 18, and a fixing screw 20 is provided on the upper cover plate 19, and the fixing screw 20 extends into the first universal angle 16; a first vertical pole 28 is provided below a fixing bolt 7 located in the second base 3, a first spring 29 is sleeved below the first vertical pole 28, the top end of the first spring 29 is fixedly connected to the first vertical pole 28, and a connecting rope 30 is provided at the bottom of the first vertical pole 28.

[0041] In the present invention, the groove 18 on the first support rod 14 that matches the protrusion 17 can facilitate the installation of the first support rod 14 and prevent the first support rod 14 from sliding downward. Then, the first support rod 14 can be further fixed by the upper cover plate 19 and the fixing screws 20.

[0042] When there is a severe situation (rain, snow, or strong wind), there is a heavy object on the photovoltaic panel pressing down on the photovoltaic panel on the second base 3. In order to maintain the overall balance of the photovoltaic panel, prevent damage to the photovoltaic panel, and prevent the photovoltaic bracket from collapsing, the photovoltaic panel on the second base 3 transfers the downward pressure to the fixing bolt 7, and transfers the downward pressure to the first vertical pole 28 through the fixing bolt 7. The first vertical pole 28 compresses the first spring 29 downward, and the first vertical pole 28 moves downward and pulls the connecting rope 30.

[0043] Reference Figure 1-Figure 9 A second vertical pole 33 is provided below a fixing bolt 7 in the first base 1 , a second spring 34 is sleeved below the second vertical pole 33 , the top end of the second spring 34 is fixedly connected to the second vertical pole 33 , and the other end of the connecting rope 30 is connected to the bottom of the second vertical pole 33 .

[0044] In the present invention, the connecting rope 30 pulls the second vertical pole 33, exerting a pulling force on the fixing bolt 7 located in the first base 1, and the force is transmitted to the photovoltaic panel located on the first base 1, so that the entire photovoltaic panel is subjected to uniform force, thereby maintaining the overall balance of the photovoltaic panel and preventing damage to the photovoltaic panel.

[0045] Reference Figure 1-Figure 9 A connecting tube 13 is provided between the first base 1 and the second base 3 , a first transmission wheel 31 and a second transmission wheel 32 are provided in the connecting tube 13 , and a connecting rope 30 is placed above the first transmission wheel 31 and the second transmission wheel 32 .

[0046] Furthermore, the connecting tube 13 can strengthen the connection strength between the first base 1 and the second base 3 to maintain the overall stability of the bracket. The connecting rope 30 is placed above the first transmission wheel 31 and the second transmission wheel 32, and the first transmission wheel 31 and the second transmission wheel 32 prevent the connecting rope 30 from escaping.

[0047] Reference Figure 1-Figure 9The first base 1 and the second base 3 are provided with multiple groups for installing multiple photovoltaic panels; an opening is opened in the middle of the fixing block 39 to facilitate the thin rod 37 to pass through; the slider 42 slides in the tube of the open tube 41, and the slider 42 will not separate from the open tube 41.

[0048] In the present invention, the first base 1 and the second base 3 can be combined to complete the large-scale installation of photovoltaic panels. An opening is opened in the middle of the fixing block 39 to facilitate the thin rod 37 to pass through. The slider 42 always slides in the tube of the open tube 41 and will not fall off.
