Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic equipment, and in particular to a connection structure and a photovoltaic bracket. Background Art
[0002] Photovoltaic equipment is generally built in mountainous areas, deserts, wetlands, rooftops and other environments. The structure of the photovoltaic bracket is the key to the successful construction of photovoltaic equipment in harsh environments. Photovoltaic brackets generally include multiple support columns, multiple top beams are set on the support columns, and steel cables are stretched between the multiple top beams. The steel cables serve as the main supporting components of photovoltaic panels. Taking the construction of photovoltaic equipment in the mountains as an example, the mountains have large ups and downs, and there will be a large angle bend between the steel cables and the top beams, which greatly affects the pulling and setting of the steel cables.
[0003] In the prior art, ear plates are welded on the top beams, and through holes are opened on the ear plates. When the steel cables are pulled, the steel cables are passed through the through holes of the ear plates for installation, thereby facilitating the pulling operation of the steel cables.
[0004] However, the defects of the prior art are: because the steel cable is generally bent at the ear plate when it is constructed and set, when the steel cable is bent at a large angle at the ear plate, and when the steel cable is pulled to construct the steel cable, the steel cable passes through the ear plate and slides relative to the ear plate, which eventually causes a large friction between the steel cable and the ear plate. In addition, since the photovoltaic bracket is set outdoors, the constructed steel cable will also be affected by the outdoor environment (such as wind), and the steel cable will also slide relative to the ear plate. Due to the large friction between the steel cable and the ear plate, the anti-corrosion coating on the surface of the steel cable is extremely easy to be worn, and even after long-term use, the body of the steel cable is also easily damaged by wear.

[0042] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0043] Combine the following Figures 1 to 7 , describing the embodiments of the connection structure and photovoltaic bracket of the utility model.
[0044] According to an embodiment of the present invention, on the one hand, a connection structure is provided, which is applied to a photovoltaic bracket, such as Figure 1 and Figure 2 As shown, the photovoltaic bracket includes a top beam 1 and a rope 2, and the connection structure includes a limiting connector 3, the limiting connector 3 is connected to the top beam 1, the limiting connector 3 and the top beam 1 together form a limiting channel 30, the rope 2 is inserted into the limiting channel 30, and the rope 2 and the limiting connector 3 are in rolling contact.
[0045] The connection structure of this embodiment is achieved by arranging a limiting connector 3 on the top beam 1, and the limiting connector 3 and the top beam 1 are combined to form a limiting channel 30, and the rope 2 is passed through the limiting channel 30, thereby realizing the limitation of the rope 2 by the limiting connector 3. On this basis, the rope 2 and the limiting connector 3 are in rolling contact, that is, there is rolling friction between the rope 2 and the limiting connector 3, which effectively reduces the friction between the rope 2 and the limiting connector 3, thereby effectively preventing the anti-corrosion coating on the surface of the rope 2 from being worn, and preventing the body of the rope 2 from being worn and damaged, thereby ensuring its service life.
[0046] The limiting connector 3 is used to limit the rope 2 in a direction perpendicular to the length direction of the rope 2, but does not affect the movement of the rope 2 along the length direction, so that the rope 2 can be built and installed on the photovoltaic bracket, so that the rope 2 can carry photovoltaic equipment such as photovoltaic panels. The limiting connector 3 of this embodiment can be directly or indirectly connected to the top beam 1, and the limiting connector 3 and the top beam 1 together form a limiting channel 30. The size of the limiting channel 30 is suitable for the rope 2 to pass through, and the inner wall of the limiting channel 30 should have a certain gap with the rope 2, so that the rope 2 can move more smoothly along its length direction under the action of the pulling force.
[0047] Furthermore, the connection structure further includes a rolling member 4, which is sleeved on the outer wall of the position-limiting connecting member 3, and the rope 2 is suitable for abutting against the rolling member 4 and driving the rolling member 4 to rotate, thereby achieving rolling cooperation between the rope 2 and the position-limiting connecting member 3.
[0048] The rolling member 4 is rotatably mounted on the outer wall of the limiting connector 3. When the rope 2 moves along its length direction under the action of the pulling force, the rope 2 will abut against the rolling member 4 and drive the rolling member 4 to rotate, thereby reducing the wear of the anti-corrosion coating on the surface of the rope 2 during the above process and reducing the resistance of the rope 2 to movement along its length direction.
[0049] Furthermore, if Figure 3As shown, the limiting connector 3 includes a limiting section 31 and two connecting sections 32, one end of the two connecting sections 32 is respectively connected to the opposite ends of the limiting section 31, and the other ends of the two connecting sections 32 are detachably connected to the top beam 1. After the limiting connector 3 is connected to the top beam 1, the limiting connector 3 and the top beam 1 are surrounded to form a limiting channel 30.
[0050] Furthermore, the limiting section 31 and the two connecting sections 32 of the limiting connecting member 3 are both provided with rolling members 4. When the rope 2 is passed through the limiting channel 30, both sides of the rope 2 and the side away from the top beam 1 are both provided with rolling members 4, thereby Figure 3 Taking the viewing angle as an example (X is the left and right direction, Y is the up and down direction), the rope 2 can be bent to the left, right and upward, and then abut the rolling member 4. The rolling cooperation between the rope 2 and the limiting connector 3 can be achieved in the above three directions, ensuring that the anti-corrosion coating on the surface of the rope 2 will not be worn, and the body of the rope 2 will not be damaged by wear.
[0051] Specifically, the limiting connector 3 in this embodiment is located above the top beam 1, so that the rope 2 can be bent to the left, to the right or upward.
[0052] Of course, in other embodiments, such as Figure 4 As shown, the limit connector 3 can also be arranged below the top beam 1, so that when the rope 2 is bent downward (i.e., the angle of the rope 2 is downward), the rope 2 contacts the roller 4 below and drives the roller 4 to rotate, thereby ensuring that when the rope 2 is bent downward, the anti-corrosion coating on the surface of the rope 2 will not be worn, and the body of the rope 2 will not be worn and damaged. It can be seen that according to actual needs, by arranging the limit connector 3 at the top, bottom or side of the top beam 1, the rope 2 can be bent in multiple directions without being worn.
[0053] Furthermore, the rolling member 4 is cylindrical, so that after the rolling member 4 is respectively sleeved on the limiting segment 31 and the two connecting segments 32 , the rolling member 4 rotates more smoothly and the friction between the rolling member 4 and the limiting connecting member 3 is smaller.
[0054] Furthermore, the number of the rolling elements 4 in this embodiment is three, one rolling element 4 is sleeved on each connecting section 32, and one rolling element 4 is sleeved on the limiting section 31, so as to ensure the smoothness of the pulling operation of the rope 2 and prevent the rope 2 from being worn.
[0055] Of course, the number of rolling elements 4 can also be six, seven, etc. Two or more rolling elements 4 are sleeved on each connecting section 32, and two or more rolling elements 4 are sleeved on the limiting section 31. The number of rolling elements 4 sleeved on the connecting section 32 and the limiting section 31 can be the same or different, and the size of each rolling element 4 can be the same or different, as long as the rope 2 and the limiting connecting element 3 can be rolled and contacted.
[0056] In other embodiments, a PE sleeve is provided in the limiting channel 30, and the rope 2 is inserted into the PE sleeve. When the rope 2 is pulled, the PE sleeve contacts the rolling element 4, further preventing the anti-corrosion coating on the surface of the rope 2 from being worn, and preventing the body of the rope 2 from being worn and damaged, thereby ensuring its service life. The PE sleeve contacts the rolling element 4 and drives the rolling element 4 to rotate, so that no large friction is generated between the PE sleeve and the rolling element 4, and the PE sleeve will not be worn or even broken, that is, through the connection structure of this embodiment, the PE sleeve can also be protected.
[0057] Furthermore, the position-limiting connector 3 is an integrated structure, and the position-limiting connector 3 is bent to form a position-limiting section 31 and two connecting sections 32. Since the rope 2 carries photovoltaic components such as photovoltaic panels, the position-limiting connector 3 will also be subjected to a large force, and the position-limiting connector 3 is an integrated structure, which ensures that the structural strength of the position-limiting connector 3 is higher, thereby preventing the position-limiting connector 3 from being damaged, and ensuring the safety of photovoltaic components such as photovoltaic panels.
[0058] Furthermore, the extension direction of the two connecting segments 32 is perpendicular to the extension direction of the limiting segment 31, and the two connecting segments 32 extend in the same direction. The connecting segment 32 and the limiting segment 31 of this solution are both straight rod structures, and the limiting connector 3 is a U-shaped structure, so that the rolling element 4 can rotate more smoothly on the connecting segment 32 or the limiting segment 31, and the friction between the rope 2 and the limiting connector 3 is further reduced.
[0059] Furthermore, a lubricating layer is provided between the rolling element 4 and the outer wall of the position-limiting connecting element 3. The friction between the rolling element 4 and the position-limiting connecting element 3 is further reduced, so that the rolling element 4 can be driven by the rope 2 to more easily rotate around the position-limiting segment 31 and the connecting segment 32 of the position-limiting connecting element 3, thereby improving the structural reliability.
[0060] Specifically, the material of the lubricating layer is polytetrafluoroethylene, which is an excellent lubricant and can effectively reduce the friction between the rolling element 4 and the limiting connector 3 .
[0061] Furthermore, if Figure 5 As shown, the limiting connecting member 3 is connected to the top beam 1 via a connecting plate 5 arranged on the top beam 1 .
[0062] In order to facilitate the connection between the limiting connector 3 and the top beam 1 , a plurality of connecting plates 5 are provided on the top beam 1 , through which the limiting connector 3 is connected to the top beam 1 , and a limiting channel 30 is formed between the limiting connector 3 and the connecting plates 5 .
[0063] Therefore, the position-limiting connector 3 of this embodiment is connected to the top beam 1 via the connecting plate 5. According to this solution, the connecting plate 5 can be first arranged at different positions of the top beam 1, and then the position-limiting connector 3 can be arranged on the connecting plate 5, thereby making the installation of the position-limiting connector 3 more convenient.
[0064] Specifically, the connecting plate 5 is welded to the top beam 1 to ensure the overall connection strength of the connecting structure, thereby ensuring that the photovoltaic bracket is more stable.
[0065] Furthermore, if Figure 6 As shown, the connection section 32 of the position-limiting connector 3 includes a screw portion 321 and a position-limiting portion 322 connected to each other, the cross-sectional dimension of the screw portion 321 perpendicular to the extension direction is smaller than the cross-sectional dimension of the position-limiting portion 322 perpendicular to the extension direction, and through holes 51 are provided at positions corresponding to the two connection sections 32 on the connection plate 5, the screw portion 321 is passed through the through holes 51, the position-limiting portion 322 abuts against the connection plate 5, and the screw portion 321 on the side of the connection plate 5 facing away from the position-limiting portion 31 is screwed and matched with the fastener 6. The structure of the connection section 32 of this embodiment makes it more convenient to install or remove the position-limiting connector 3 on the connection plate 5, greatly saving the time cost of workers.
[0066] Specifically, the fastener 6 is a nut, and through the threaded connection between the nut and the screw portion 321, the position-limiting connector 3 can be detachably arranged on the connecting plate 5, making the disassembly and assembly operation more convenient.
[0067] In other embodiments, after the screw portion 321 of the connecting section 32 passes through the through hole 51 of the connecting plate 5, the fastener 6 is fixedly connected to the screw portion 321, and specifically, the fastener 6 and the screw portion 321 can be welded, and at this time, the screw portion 321 of the limiting connector 3 is slidably matched with the through hole 51 of the connecting plate 5 (the screw portion 321 can slide in the through hole 51), that is, the limiting connector 3 can move in the direction close to or away from the connecting plate 5, but the limiting connector 3 will not be separated from the connecting plate 5. When the rope 2 needs to pass through the limiting channel 30 between the limiting connector 3 and the connecting plate 5, the limiting connector 3 is first pulled up in the direction away from the connecting plate 5, and then the rope 2 is passed through the limiting channel 30, but it should be ensured that the gap between the rope 2 and the inner wall of the limiting channel 30 is not too large, so as not to affect the limiting of the rope 2 by the limiting channel 30 in the direction perpendicular to its length.
[0068] In other embodiments, the screw portion 321 of the position-limiting connector 3 is welded to the connecting plate 5 to increase the overall connection strength of the connecting structure.
[0069] According to an embodiment of the present utility model, a photovoltaic bracket is also provided, such as Figure 7 As shown, the photovoltaic support includes a top beam 1, a rope 2, a support column 7 and the above-mentioned connection structure, the top beam 1 is arranged on the top of the support column 7, and the connection structure is arranged on the top beam 1. When the photovoltaic support is performing the rope 2 pulling operation, the anti-corrosion coating on the surface of the rope 2 will not be worn and damaged, thereby ensuring the overall safety of the photovoltaic support.
