Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to a vibration damping device for a flexible photovoltaic support. Background Technology

[0002] Photovoltaic power generation is one of the most important forms of solar energy utilization today. Photovoltaic power generation devices typically use photovoltaic (PV) brackets to support and fix the PV modules. These brackets can be flexible. Current flexible PV brackets involve fixing tensioned steel cables to a steel frame, and then mounting the PV modules onto the tensioned steel cables. Due to the large size of PV modules, two steel cables are usually used to support them.

[0003] However, because the stiffness of the flexible support structure is much smaller than that of the conventional fixed support structure, the steel cable will swing irregularly with a large amplitude under the wind. This causes the photovoltaic module to be subjected to the torsion and shearing action of the steel cable, resulting in microcracks in the photovoltaic module cells and ultimately causing the photovoltaic module to fail to generate electricity normally.

[0004] Therefore, a vibration damping device needs to be invented to solve the problem of photovoltaic module damage caused by the large swing of the steel cable mentioned above. Summary of the Invention

[0005] The main objective of this invention is to provide a vibration damping device for a flexible photovoltaic support to solve the problem of damage to photovoltaic modules caused by large-scale swaying of steel cables.

[0006] To achieve the above objectives, the present invention provides a vibration damping device for a flexible photovoltaic support, comprising a first belt cloth; the first belt cloth is draped over two sets of steel cables of the flexible photovoltaic support; the first belt cloth includes a lower wide surface and an upper wide surface facing away from each other; the lower wide surface is attached to the steel cables, and a buffer air bag is fixed in the middle of the lower wide surface; the length direction of the buffer air bag is the same as the length direction of the first belt cloth; one end of the buffer air bag cooperates with one side of the lower wide surface to clamp one set of steel cables, and the other end of the buffer air bag cooperates with the other side of the lower wide surface to clamp another set of steel cables; one end of the first belt cloth is fixed with a hook and loop fastener, and the other end of the first belt cloth is fixed with a hook and loop fastener; the hook and loop fastener are paired; the hook and loop fastener is located on the lower wide surface, and the hook and loop fastener is located on the upper wide surface.

[0007] Optionally, both ends of the buffer air bag are fixed with edge strips; the edge strips correspond to the steel cables; both ends of the buffer air bag clamp the steel cables through the edge strips and the lower wide surface.

[0008] Optionally, the upper wide surface is provided with two sets of brushes; the arrangement direction of the two sets of brushes is the same as the length direction of the first belt cloth; the two sets of brushes are respectively located on both sides of the buffer air bag.

[0009] Optionally, each set of brushes includes two rows of bristles; the arrangement direction of each row of bristles is the same as the width direction of the first belt cloth; the vibration damping device of the flexible photovoltaic bracket also includes two sets of linkage plates corresponding one-to-one with the two sets of brushes; the length direction of the linkage plate is the same as the arrangement direction of a single row of bristles; both rows of bristles are fixed to the linkage plates.

[0010] Optionally, the linkage plate is provided with multiple sets of weight-reducing through grooves along its length.

[0011] Optionally, the vibration damping device of the flexible photovoltaic bracket further includes a second belt and a third belt that hang below the two sets of steel cables; both the second belt and the third belt are for users to pull; one end of the first belt is fixed to the second belt, and the other end of the first belt is fixed to the third belt; the first belt symmetry plane corresponding to the first belt and perpendicular to its width direction, the second belt symmetry plane corresponding to the second belt and perpendicular to its width direction, and the third belt symmetry plane corresponding to the third belt and perpendicular to its width direction coincide;

[0012] The density of the gas inside the cushioning air bag is less than the density of air; the total weight of the first belt fabric, the second belt fabric, the third belt fabric, the hook and loop fastener, and the hook and loop fastener is less than the buoyancy of the cushioning air bag.

[0013] Optionally, the vibration damping device of the flexible photovoltaic bracket further includes a first connecting piece and a second connecting piece; one end of the first belt fabric is provided with a first mounting groove adapted to the first connecting piece, and the other end is provided with a second mounting groove adapted to the second connecting piece; both the first connecting piece and the second connecting piece are fixed to the first belt fabric; the second belt fabric and the hook and loop fastener are both fixed to one side surface of the first connecting piece; both sides of the second connecting piece are respectively fixed to the third belt fabric and the hook and loop fastener.

[0014] The vibration damping device provided by this invention can buffer the swaying of steel cables, thereby reducing the negative impact on photovoltaic modules and enabling them to operate normally and have a longer service life. The specific usage process of the vibration damping device is as follows: First, a first belt cloth is draped over the two steel cables, so that the buffer air bag is located between the two sets of steel cables. Then, the hook and loop sides of the Velcro are attached together. One end of the buffer air bag mates with one side of the lower wide surface to clamp one set of steel cables, and the other end of the buffer air bag mates with the other side of the lower wide surface to clamp the other set of steel cables. This completes the installation of the vibration damping device onto the two steel cables. As can be seen from the aforementioned usage process, the vibration damping device has a simple and lightweight structure and is easy to install. The specific vibration reduction process is as follows: when the steel cable swings outward, it pushes the first belt cloth outward. Affected by the first belt cloth, the buffer air bag flattens and then returns to its original shape, thereby achieving vibration reduction; when the steel cable swings inward, it pushes the buffer air bag inward, the buffer air bag bulges and then returns to its original shape, thereby achieving vibration reduction; in addition, the first belt cloth has good wear resistance and can maintain good working performance by being in close contact with the steel cable for a long time.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] This invention provides a vibration damping device for a flexible photovoltaic support, such as... Figures 1-6 As shown, it includes a first belt fabric 10; the first belt fabric 10 is draped over two sets of steel cables 2 of the photovoltaic flexible support; the first belt fabric 10 includes a lower wide surface 180 and an upper wide surface 181 facing away from each other; the lower wide surface 180 is attached to the steel cables 2, and a buffer air bag 11 is fixed in the middle of the lower wide surface 180; the length direction of the buffer air bag 11 is the same as the length direction of the first belt fabric 10; one end of the buffer air bag 11 cooperates with one side of the lower wide surface 180 to clamp one set of steel cables 2, and the other end of the buffer air bag 11 cooperates with the other side of the lower wide surface 180 to clamp another set of steel cables 2; one end of the first belt fabric 10 is fixed with a hook and loop fastener 12, and the other end of the first belt fabric 10 is fixed with a hook and loop fastener 13; the hook and loop fastener 12 and the hook and loop fastener 13 are paired; the hook and loop fastener 12 is located on the lower wide surface 180, and the hook and loop fastener 13 is located on the upper wide surface 181.

[0024] The vibration damping device described above can buffer the swaying of the steel cables 2, thereby reducing the negative impact on the photovoltaic modules and enabling them to operate normally and have a longer service life. The specific usage process of the vibration damping device is as follows: First, the first belt cloth 10 is draped over the two steel cables 2, so that the buffer air bag 11 is located between the two sets of steel cables 2. Then, the hook and loop fasteners 12 and 13 are attached together. One end of the buffer air bag 11 engages with one side of the lower wide surface 180 to clamp one set of steel cables 2, and the other end of the buffer air bag 11 engages with the other side of the lower wide surface 180 to clamp the other set of steel cables 2. This completes the installation of the vibration damping device onto the two steel cables 2. As can be seen from the aforementioned usage process, the vibration damping device has a simple and lightweight structure and is easy to install. The specific vibration reduction process is as follows: when the steel cable 2 swings outward, it pushes the first belt cloth 10 outward. Affected by the first belt cloth 10, the buffer air bag 11 flattens and then returns to its original shape, thereby achieving vibration reduction; when the steel cable 2 swings inward, it pushes the buffer air bag 11 inward, the buffer air bag 11 bulges and then returns to its original shape, thereby achieving vibration reduction; in addition, the first belt cloth 10 has good wear resistance and can maintain good working performance by being in long-term contact with the steel cable 2.

[0025] Optionally, the cushioning air bag 11 is fixed to the first belt cloth 10 with glue.

[0026] Optionally, both ends of the cushioning air bag 11 are fixed with edge strips 14; the edge strips 14 correspond to the steel cable 2; both ends of the cushioning air bag 11 are clamped to the steel cable 2 by the edge strips 14 and the lower wide surface 180. The edge strips 14 can increase the friction with the rope 2, making the position of the vibration damping device on the rope 2 more stable and less prone to shifting, and can also protect the cushioning air bag 11. That is, the edge strips 14 replace the cushioning air bag 11 to bear the scraping of the rope 2.

[0027] Optionally, the upper wide surface 181 is provided with two sets of brushes 15; the arrangement direction of the two sets of brushes 15 is the same as the length direction of the first belt cloth 10; the two sets of brushes 15 are located on both sides of the buffer air bag 11; the brushes 15 have two functions: first, to clean the photovoltaic module, by tearing the hook side 12 off the hook side 13, the first belt cloth 10 is in a free state, and the buffer air bag 11 can be used as a brush handle to clean the photovoltaic module with the two sets of brushes 15 to prevent dust from adhering to the photovoltaic module; second, to further optimize the vibration reduction effect, when the vibration reduction device is performing vibration reduction, both sets of brushes 15 can be used as the windward surface to increase the pushing force required to push the steel cable 2.

[0028] Optionally, each set of brushes 15 includes two rows of bristles 16; the arrangement direction of each row of bristles 16 is the same as the width direction of the first belt fabric 10; the vibration damping device of the flexible photovoltaic bracket also includes two sets of linkage plates 17 corresponding one-to-one with the two sets of brushes 15; the length direction of the linkage plate 17 is the same as the arrangement direction of a single row of bristles 16; both rows of bristles 16 are fixed to the linkage plate 17, further optimizing the vibration damping effect. Optionally, the bristles 16 are fixed to the first belt fabric 10 with glue, and the linkage plate 17 is fixed to the bristles 16 with glue.

[0029] Optionally, the linkage plate 17 is provided with multiple sets of weight-reducing through grooves 182 along its length.

[0030] Optionally, the vibration damping device of the flexible photovoltaic support also includes a second belt 18 and a third belt 19 that hang below the two sets of steel cables 2; both the second belt 18 and the third belt 19 are for users to pull; one end of the first belt 10 is fixed to the second belt 18, and the other end of the first belt 10 is fixed to the third belt 19; the first belt symmetry plane corresponding to the first belt 10 and perpendicular to its width direction, the second belt symmetry plane corresponding to the second belt 18 and perpendicular to its width direction, and the third belt symmetry plane corresponding to the third belt 19 and perpendicular to its width direction coincide;

[0031] The density of the gas inside the cushioning air bag 11 is less than the density of air; the total weight of the first belt fabric 10, the second belt fabric 18, the third belt fabric 19, the hook and loop fastener 12, and the hook and loop fastener 13 is less than the buoyancy of the cushioning air bag 11.

[0032] The structure described above facilitates the removal of the hook and loop fastener 12 from the hook and loop hook fastener 13, and also facilitates the cleaning of the photovoltaic modules. Specifically, the user does not need to climb to a high place; simply standing on the ground, the user pulls the second belt fabric 18 with one hand and the third belt fabric 19 with the other, that is, pulls the second belt fabric 18 and the third belt fabric 19 in different directions to separate the hook and loop fastener 12 from the hook and loop hook fastener 13. Furthermore, since the total weight of the first belt fabric 10, the second belt fabric 18, the third belt fabric 19, the hook and loop fastener 12, and the hook and loop hook fastener 13 is less than the buoyancy of the cushioning air bag 11, the hook and loop fastener 12 and the hook and loop hook fastener 13 can be easily separated. After the Velcro hook 13 is separated, without external pulling, the cushioning air bag 11 will rise, pulling the second belt cloth 18 and the third belt cloth 19, so that the cushioning air bag 11 moves above the photovoltaic module. Then, by flipping the second belt cloth 18 and the third belt cloth 19, the user can also flip the first belt cloth 10 so that its attached brush 15 faces downward. Then, by pulling up or down the second belt cloth 18 and the third belt cloth 19, the user can use the brush 15 to clean the photovoltaic module. As can be seen from the above usage process, the entire cleaning process is conducive to protecting the user's personal safety and is easy to operate.

[0033] Optionally, the vibration damping device of the flexible photovoltaic bracket also includes a first connecting piece 20 and a second connecting piece 21; one end of the first belt fabric 10 is provided with a first mounting groove 183 adapted to the first connecting piece 20, and the other end is provided with a second mounting groove 184 adapted to the second connecting piece 21; both the first connecting piece 20 and the second connecting piece 21 are fixed to the first belt fabric 10; the second belt fabric 18 and the hook and loop fastener 13 are both fixed to one side surface of the first connecting piece 20; both sides of the second connecting piece 21 are respectively fixed to the third belt fabric 19 and the hook and loop fastener 12; by adding the first connecting piece 20 and the second connecting piece 21, the installation of the second belt fabric 18, the hook and loop fastener 13, the third belt fabric 19, and the hook and loop fastener 12 is facilitated, and it is also easier to peel the hook and loop fastener 12 off the hook and loop fastener 13. Optionally, both the first connecting piece 20 and the second connecting piece 21 are fixed to the first belt fabric 10 with glue.
