Abstract
Description
Technical Field
[0001] The invention relates to a wind-resistant flexible photovoltaic support structure, belonging to the technical field of photovoltaic supports. Background Art
[0002] Under the action of wind, the flexible bracket will be tilted due to the photovoltaic panel. If the wind direction is toward the back of the photovoltaic panel, the wind load at the bottom of the photovoltaic panel will be greater than the wind load at the top, which will lead to the following problems: 1) Photovoltaic panels can be easily overturned from the bottom; 2) In this case, the photovoltaic panel will tilt more and more due to the lower wind load being greater than the upper wind load, which will cause the wind load to become greater and greater, making the photovoltaic panel more likely to be twisted or overturned. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide a wind-resistant flexible photovoltaic support group structure to overcome the deficiencies of the prior art.
[0004] The technical solution of the present invention is: A wind-resistant flexible photovoltaic bracket group structure, comprising a plurality of groups of mutually parallel photovoltaic brackets and a third cable; The photovoltaic support comprises a photovoltaic assembly support frame, a support shaft, a seesaw structure, a first cable and a second cable; The middle part of the photovoltaic module support frame is fixedly connected to the support shaft, the support shaft is parallel to the edge of the lower part or the upper part of the inclined surface of the photovoltaic module support frame, and the photovoltaic module support frame rotates around the support shaft so that the inclination angle of the photovoltaic module support frame changes; The rotation axis of the seesaw structure is parallel to the support rotation axis; The lower side of the photovoltaic module support frame after the tilted installation is set as the first horizontal side, and the higher side of the photovoltaic module support frame after the tilted installation is set as the second horizontal side; The two ends of the first cable are respectively connected to the second horizontal edge of the photovoltaic module support frame and the end of the seesaw structure on the same side; One end of the second cable is connected to the rotating shaft of the seesaw structure, and the other end of the second cable is connected to the first horizontal edge of the photovoltaic module support frame; One end of the third cable is connected to the end of the seesaw structure on the same side as the first horizontal edge of the seesaw structure of the photovoltaic support in this group, and the other end of the third cable is connected to the second horizontal edge of the photovoltaic component support frame of the adjacent photovoltaic support.
[0005] Furthermore, it also includes a cross, which includes two intersecting and fixed cylinders, the inner diameters of the two cylinders match the wire diameters of the third cable and the second cable respectively, and the first cable of this group of photovoltaic brackets and the second cable of the adjacent group of photovoltaic brackets pass through the two corresponding cylinders of the cross respectively.
[0006] Optionally, a spring is further included, and the spring is arranged between two ends of the seesaw structure and the ground.
[0007] Optionally, a damper is further included, and the damper is arranged between two ends of the seesaw structure and the ground.
[0008] The beneficial effects of the present invention are: compared with the prior art, 1) The present invention links the adjacent groups of photovoltaic brackets through a seesaw structure. When the wind load on the lower part of the photovoltaic assembly is greater than the wind load on the upper part, the photovoltaic assembly support frame rotates around the support shaft to increase the inclination angle of the photovoltaic assembly support frame, thereby pulling the third cable, and the third cable will pull the seesaw structure of the adjacent group of photovoltaic brackets. The rotation of the seesaw structure of the adjacent group of photovoltaic brackets will pull the corresponding second cable, and the pulling of the second cable will reduce the inclination angle of the photovoltaic assembly support frame of the adjacent group of photovoltaic brackets. The corresponding first cable will limit the inclination angle of the photovoltaic assembly support frame to a certain range, thereby limiting the rotation angle of the corresponding seesaw structure to a certain range, so that the inclination angle of the photovoltaic assembly support frame of the current group of photovoltaic brackets will not continue to increase, and all groups of photovoltaic assembly support frames under this structure will not be overturned; 2) The present invention has a negative feedback mechanism. When the inclination angle of any group of photovoltaic module support frames increases, it will be restricted by other groups of photovoltaic brackets, so that the inclination angle of the photovoltaic module support frames of other groups of photovoltaic brackets decreases. The situation where the greater the inclination of the photovoltaic panel, the greater the wind load will be will not occur, and the photovoltaic panel is less likely to be twisted or overturned; 3) The present invention connects the first cable of the photovoltaic bracket group and the third cable between the adjacent photovoltaic bracket group (the adjacent photovoltaic bracket group is the photovoltaic bracket close to the first horizontal edge of the photovoltaic bracket group) through a cross, so that the distance between the first cable and the third cable is limited to a certain range, so as to avoid the distance between the two being too large, thereby preventing the photovoltaic module support frame from generating too large a torque perpendicular to the paper surface, thereby protecting the photovoltaic module and preventing the photovoltaic module from being twisted; 4) The present invention uses springs or dampers to dissipate the energy of the entire system during the rotation of the seesaw structure.

[0010] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings of this specification.
[0011] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.
[0012] For the convenience of description, the present invention uses the directional words such as this group, adjacent, higher and lower. The definitions of these directional words in this patent are as follows: this group is not limited to a specific photovoltaic bracket, but any photovoltaic bracket can be called this group. In order to facilitate the description of the positional relationship with the adjacent group of photovoltaic brackets, the present invention uses the directional word this group. Similarly, adjacent is a word relative to this group, which indicates that the photovoltaic brackets adjacent to this group are all adjacent. Higher corresponds to Figure 1 The middle is closer to the upper part, and the lower is the opposite.
[0013] Embodiment 1: refer to Figure 1 , a wind-resistant flexible photovoltaic bracket group structure, comprising a plurality of groups of mutually parallel photovoltaic brackets and a third cable 6; The photovoltaic support comprises a photovoltaic assembly support frame 1, a support shaft 3, a seesaw structure 2, a first cable 5 and a second cable 4; The middle part of the photovoltaic module support frame 1 is fixedly connected to the support shaft 3, and the support shaft 3 is parallel to the edge of the lower or upper part of the inclined surface of the photovoltaic module support frame 1. The photovoltaic module support frame 1 rotates around the support shaft 3 so that the inclination angle of the photovoltaic module support frame 1 changes; The rotation axis of the seesaw structure 2 is parallel to the support rotation axis 3; The lower side of the photovoltaic module support frame 1 after the tilted installation is set as the first horizontal side, and the higher side of the photovoltaic module support frame 1 after the tilted installation is set as the second horizontal side; The two ends of the first cable 5 are respectively connected to the second horizontal edge of the photovoltaic module support frame 1 and the end of the seesaw structure 2 on the same side; One end of the second cable 4 is connected to the rotating shaft of the seesaw structure 2, and the other end of the second cable 4 is connected to the first horizontal edge of the photovoltaic module support frame 1; One end of the third cable 6 is connected to the end of the seesaw structure 2 on the same side as the first horizontal edge of the seesaw structure 2 of the photovoltaic support in this group, and the other end of the third cable 6 is connected to the second horizontal edge of the photovoltaic component support frame 1 of the adjacent photovoltaic support.
[0014] The photovoltaic brackets of adjacent groups are linked by the seesaw structure 2. When the wind load on the lower part of the photovoltaic module is greater than the wind load on the upper part, the photovoltaic module support frame 1 rotates around the support shaft 3 so that the inclination angle of the photovoltaic module support frame 1 increases. The direction in which the inclination angle of the photovoltaic module support frame 1 increases is as follows: Figure 1 or Figure 2As shown in a, the third cable 6 is pulled, and the pulling direction of the third cable 6 is as shown in Figure 1 or Figure 2 As shown in b, the third cable 6 will pull the seesaw structure 2 of the adjacent photovoltaic bracket group, and the seesaw structure 2 rotates in the direction shown in FIG. Figure 1 or Figure 2 As shown in c and d, the rotation of the seesaw structure 2 of the adjacent photovoltaic bracket group will pull the corresponding second cable 4. The pulling direction of the second cable 4 is as follows: Figure 1 or Figure 2 As shown in Figure e, the second cable 4 is pulled to reduce the inclination angle of the photovoltaic component support frame 1 of the adjacent photovoltaic bracket group. The direction of the reduction of the inclination angle of the photovoltaic component support frame 1 of the adjacent photovoltaic bracket group is as follows: Figure 1 or Figure 2 As shown in f, the corresponding first cable 5 will limit the inclination angle of the photovoltaic module support frame 1 to a certain range, thereby limiting the rotation angle of the corresponding seesaw structure 2 to a certain range, so that the inclination angle of the photovoltaic module support frame 1 of this group of photovoltaic brackets will not continue to increase, so that all groups of photovoltaic module support frames 1 under this structure will not be overturned. The present invention has a negative feedback mechanism, and the increase in the inclination angle of any group of photovoltaic module support frames 1 will be restricted by other groups of photovoltaic brackets, so that the inclination angle of the photovoltaic module support frames 1 of other groups of photovoltaic brackets is reduced, and the situation that the greater the inclination of the photovoltaic panel, the greater the wind load will not occur, and the photovoltaic panel is less likely to be twisted or overturned.
[0015] In order to avoid the distance between the first cable 5 and the third cable 6 being too large, which would cause an excessive torque perpendicular to the paper surface to the photovoltaic module support frame 1, the present embodiment further includes a cross, which includes two intersecting and fixed cylinders, the inner diameters of which are respectively matched with the diameters of the third cable 6 and the second cable 4, and the first cable 5 of the photovoltaic bracket of this group and the second cable 4 of the photovoltaic bracket of the adjacent group pass through the two corresponding cylinders of the cross respectively. The first cable 5 of the photovoltaic bracket of this group and the third cable 6 between the photovoltaic brackets of the adjacent group (the photovoltaic brackets of the adjacent group are the photovoltaic brackets close to the first horizontal edge of the photovoltaic brackets of this group) are connected by the cross, so that the distance between the first cable 5 and the third cable 6 is limited within a certain range, so as to avoid the distance between the two being too large, which would cause an excessive torque perpendicular to the paper surface to the photovoltaic module support frame 1, thereby protecting the photovoltaic module and preventing the photovoltaic module from being twisted.
[0016] In order to increase the speed of energy dissipation of the system to avoid damage caused by vibration of the photovoltaic components, in this embodiment, optionally, a spring 7a is further included, and the spring 7a is arranged between the two ends of the seesaw structure 2 and the ground.
[0017] Embodiment 2: refer to Figure 2, a wind-resistant flexible photovoltaic bracket group structure, comprising a plurality of groups of mutually parallel photovoltaic brackets and a third cable 6; The photovoltaic support comprises a photovoltaic assembly support frame 1, a support shaft 3, a seesaw structure 2, a first cable 5 and a second cable 4; The middle part of the photovoltaic module support frame 1 is fixedly connected to the support shaft 3, and the support shaft 3 is parallel to the edge of the lower or upper part of the inclined surface of the photovoltaic module support frame 1. The photovoltaic module support frame 1 rotates around the support shaft 3 so that the inclination angle of the photovoltaic module support frame 1 changes; The rotation axis of the seesaw structure 2 is parallel to the support rotation axis 3; The lower side of the photovoltaic module support frame 1 after the tilted installation is set as the first horizontal side, and the higher side of the photovoltaic module support frame 1 after the tilted installation is set as the second horizontal side; The two ends of the first cable 5 are respectively connected to the second horizontal edge of the photovoltaic module support frame 1 and the end of the seesaw structure 2 on the same side; One end of the second cable 4 is connected to the rotating shaft of the seesaw structure 2, and the other end of the second cable 4 is connected to the first horizontal edge of the photovoltaic module support frame 1; One end of the third cable 6 is connected to the end of the seesaw structure 2 on the same side as the first horizontal edge of the seesaw structure 2 of the photovoltaic support in this group, and the other end of the third cable 6 is connected to the second horizontal edge of the photovoltaic component support frame 1 of the adjacent photovoltaic support.
[0018] The photovoltaic brackets of adjacent groups are linked by the seesaw structure 2. When the wind load on the lower part of the photovoltaic module is greater than the wind load on the upper part, the photovoltaic module support frame 1 rotates around the support shaft 3 so that the inclination angle of the photovoltaic module support frame 1 increases. The direction in which the inclination angle of the photovoltaic module support frame 1 increases is as follows: Figure 1 or Figure 2 As shown in a, the third cable 6 is pulled, and the pulling direction of the third cable 6 is as shown in Figure 1 or Figure 2 As shown in b, the third cable 6 will pull the seesaw structure 2 of the adjacent photovoltaic bracket group, and the seesaw structure 2 rotates in the direction shown in FIG. Figure 1 or Figure 2 As shown in c and d, the rotation of the seesaw structure 2 of the adjacent photovoltaic bracket group will pull the corresponding second cable 4. The pulling direction of the second cable 4 is as follows: Figure 1 or Figure 2 As shown in Figure e, the second cable 4 is pulled to reduce the inclination angle of the photovoltaic component support frame 1 of the adjacent photovoltaic bracket group. The direction of the reduction of the inclination angle of the photovoltaic component support frame 1 of the adjacent photovoltaic bracket group is as follows: Figure 1 or Figure 2As shown in f, the corresponding first cable 5 will limit the inclination angle of the photovoltaic module support frame 1 to a certain range, thereby limiting the rotation angle of the corresponding seesaw structure 2 to a certain range, so that the inclination angle of the photovoltaic module support frame 1 of this group of photovoltaic brackets will not continue to increase, so that all groups of photovoltaic module support frames 1 under this structure will not be overturned. The present invention has a negative feedback mechanism, and the increase in the inclination angle of any group of photovoltaic module support frames 1 will be restricted by other groups of photovoltaic brackets, so that the inclination angle of the photovoltaic module support frames 1 of other groups of photovoltaic brackets is reduced, and the situation that the greater the inclination of the photovoltaic panel, the greater the wind load will not occur, and the photovoltaic panel is less likely to be twisted or overturned.
[0019] In order to avoid the distance between the first cable 5 and the third cable 6 being too large, which would cause an excessive torque perpendicular to the paper surface to the photovoltaic module support frame 1, the present embodiment further includes a cross, which includes two intersecting and fixed cylinders, the inner diameters of which are respectively matched with the diameters of the third cable 6 and the second cable 4, and the first cable 5 of the photovoltaic bracket of this group and the second cable 4 of the photovoltaic bracket of the adjacent group pass through the two corresponding cylinders of the cross respectively. The first cable 5 of the photovoltaic bracket of this group and the third cable 6 between the photovoltaic brackets of the adjacent group (the photovoltaic brackets of the adjacent group are the photovoltaic brackets close to the first horizontal edge of the photovoltaic brackets of this group) are connected by the cross, so that the distance between the first cable 5 and the third cable 6 is limited within a certain range, so as to avoid the distance between the two being too large, which would cause an excessive torque perpendicular to the paper surface to the photovoltaic module support frame 1, thereby protecting the photovoltaic module and preventing the photovoltaic module from being twisted.
[0020] In order to increase the speed of energy dissipation of the system to avoid damage caused by vibration of the photovoltaic components, in this embodiment, optionally, a damper 7b is also included, and the damper 7b is arranged between the two ends of the seesaw structure 2 and the ground.
