[0049] This invention proposes a photovoltaic bracket 100.

[0050] In embodiments of the present invention, such as Figures 1 to 11 As shown, the photovoltaic support 100 includes multiple support frames, a rope assembly 110, multiple photovoltaic modules 130, and a flexible component 140. The rope assembly 110 is disposed between two adjacent support frames and includes a photovoltaic rope 111 and an auxiliary rope 112. The photovoltaic rope 111 and the auxiliary rope 112 are connected by a pulley block 120, so that the auxiliary rope 112 pulls the photovoltaic rope 111 taut. Multiple photovoltaic modules 130 are arranged at intervals on the photovoltaic rope 111. The flexible component 140 is disposed on the auxiliary rope 112 and extends along the extension direction of the auxiliary rope 112, and the flexible component 140 is set at an angle to the photovoltaic module 130.

[0051] The flexible component 140 has at least one auxiliary surface 150. Under the action of wind, a pressure difference is formed between the top and bottom of the auxiliary surface 150, causing the flexible component 140 to deform or deflect, so as to provide tension for the auxiliary rope 112.

[0052] Specifically, a plurality of support frames are arranged on the ground in a spaced manner, a rope assembly 110 is arranged between two adjacent support frames, and is used to bear the installation of the photovoltaic assembly 130. The rope assembly 110 includes a photovoltaic rope 111 and an auxiliary rope 112. The photovoltaic assembly 130 is arranged on the photovoltaic rope 111 to form a row, and the photovoltaic ropes 111 are arranged in a spaced manner along the extension direction of the support frame, so that each row of photovoltaic assemblies 130 is arranged in a spaced manner along the extension direction of the support frame. In order to improve the working efficiency of the photovoltaic assembly 130, the photovoltaic assembly 130 is generally arranged to be inclined compared to the ground. In other embodiments, the photovoltaic assembly 130 can also be arranged horizontally. In order to reduce the possibility of mutual shielding of the photovoltaic assemblies 130 in two adjacent rows, the gap between the photovoltaic assemblies 130 in the two adjacent rows is greater than or equal to the length of the photovoltaic assembly 130, and the flexible assembly 140 is arranged in the gap. The length direction of the photovoltaic assembly 130 is the same as the arrangement direction of the plurality of rows of photovoltaic assemblies 130, and is arranged to be substantially perpendicular to the extension direction of the photovoltaic rope 111 and the auxiliary rope 112. Since the photovoltaic support 100 is a flexible photovoltaic support 100, the photovoltaic assemblies 130 can only rely on the photovoltaic rope 111 to be tensioned, and sufficient pre-tightening force can be provided for the photovoltaic support 100 during installation. However, with the extension of the use time, the influence of temperature changes and wind factors, and the like, the photovoltaic support 100 will inevitably have a decrease in pre-tightening force, so that the rope assembly 110 is loose, the movement amplitude of the photovoltaic support 100 increases under the action of wind, and the photovoltaic support 100 is prone to overall instability, and the risk of fatigue failure increases.

[0053] To solve this problem, reduce the risk of overall instability and fatigue failure of the photovoltaic support 100, and improve the service life of the photovoltaic support 100. The present scheme refers to the structure of a dragonfly wing and the principle of pressure difference. The dragonfly can hover and glide in the air without flapping its wings in a slight wind. The thickness of the dragonfly's wing is only 0.03 mm. The wing structure is not smooth, has an angle and a groove, and under the action of the incoming flow wind, the groove on the upper surface of the wing generates a turbulent vortex, and the lower surface does not have a vortex. The rotation of the cyclone will make the surrounding airflow accelerate continuously. According to Bernoulli's principle, the place with high flow rate has low pressure, and the place with low flow rate has high pressure. There are cyclones on the upper surface of the dragonfly's wing, the flow rate is high, the pressure is low, there are no cyclones on the lower surface, the flow rate is low, and the pressure is high. An upward pressure difference is generated between the upper and lower surfaces. The pressure difference is the lifting force, and the cyclones are the power source for the dragonfly to hover and glide.

[0054] The photovoltaic array formed by the photovoltaic components 130 is like a row of photovoltaic planes 131, and on this basis, the flexible components 140 are fixed on the auxiliary rope 112, and the flexible components 140 form an auxiliary plane 150, which is arranged at an angle with the photovoltaic plane 131, so that the photovoltaic plane 131 and the auxiliary plane 150 jointly constitute an irregular surface like a dragonfly wing. The flow speed is different at the groove, a cyclone is generated, and the upper and lower surface pressure differences of the auxiliary plane 150 are formed. Under the action of wind force, the auxiliary plane 150 is deformed, or the flexible components 140 are deflected relative to the photovoltaic components 130 as a whole, so that the auxiliary rope 112 is deformed and tensioned, and the deformation amount is conducted through the pulley set 120, so that the auxiliary rope 112 tightens the photovoltaic rope 111, thereby improving the tension of the photovoltaic rope 111. The greater the wind speed, the greater the deformation amount of the flexible components 140, and the greater the tension of the auxiliary rope 112 on the photovoltaic components 130, so that the flexible photovoltaic support 100 automatically adjusts the tension under the action of wind force, and the higher the wind speed, the greater the tension, thereby effectively resisting the wind load.

[0055] In combination with reference Figures 1 to 5 When the angle between the photovoltaic components 130 and the ground is greater than 15°, the angle between the flexible components 140 and the photovoltaic components 130 is smaller, and under the action of wind force, a cyclone is formed above and / or below the auxiliary plane 150, thereby changing the pressure difference above and below the auxiliary plane 150; when the angle between the photovoltaic components 130 and the ground is greater than or equal to 0° and less than or equal to 15°, the angle between the flexible components 140 and the photovoltaic components 130 is larger, and the inclination angle of the photovoltaic components 130 is too small to form a cyclone, but the auxiliary plane 150 forms an angle with the photovoltaic plane 131, and after the incoming wind passes through the angle, the flow speed above and below the auxiliary plane 150 changes, so that the pressure difference above and below the auxiliary plane 150 is formed, thereby causing the flexible components 140 to be deflected relative to the photovoltaic components 130 as a whole, so that the auxiliary rope 112 is deformed, thereby tightening the photovoltaic rope 111 and improving the tension of the photovoltaic support 100.

[0056] The technical scheme of the present application sets multiple support frames, the rope assembly 110 is arranged between two adjacent support frames, the rope assembly 110 comprises a photovoltaic rope 111 and an auxiliary rope 112, the photovoltaic rope 111 and the auxiliary rope 112 are connected through a pulley set 120, so as to conduct the deformation amount, so that the auxiliary rope 112 tightens the photovoltaic rope 111. Multiple photovoltaic assemblies 130 are arranged on the photovoltaic rope 111 at intervals. A flexible assembly 140 is arranged on the auxiliary rope 112 and extends along the extension direction of the auxiliary rope 112, and the flexible assembly 140 is arranged at an angle with the photovoltaic assembly 130. The flexible assembly 140 is formed with at least one auxiliary surface 150. Referring to the structure of a dragonfly wing and the principle of pressure difference, the photovoltaic array formed by the photovoltaic assembly 130 is like a column of photovoltaic planes 131, so on this basis, the flexible assembly 140 is fixed on the auxiliary rope 112, the flexible assembly 140 forms the auxiliary surface 150, the auxiliary surface 150 is arranged at an angle with the photovoltaic plane 131, so that the photovoltaic plane 131 and the auxiliary surface 150 jointly construct an irregular surface like a dragonfly wing, the flow velocity of the incoming wind is different at the groove, a cyclone is generated, the upper and lower surface pressure differences of the auxiliary surface 150 are formed, the flexible assembly 140 is deformed or deflected, and then the auxiliary rope 112 is deformed and tensioned, and the deformation amount is conducted through the pulley set 120, so that the auxiliary rope 112 tightens the photovoltaic rope 111, and then the tensioning force of the photovoltaic rope 111 is improved. The greater the wind speed is, the greater the deformation amount of the flexible assembly 140 is, and the greater the tensioning force of the auxiliary rope 112 on the photovoltaic assembly 130 is, so that the flexible photovoltaic support 100 realizes the effect that the tensioning force is automatically adjusted under the action of wind force, and the higher the wind speed is, the greater the tensioning force is, thereby effectively resisting the wind load.

[0057] In an embodiment, the flexibility of the flexible assembly 140 is greater than that of the photovoltaic assembly 130. That is, the rigidity of the flexible assembly 140 is less than that of the photovoltaic assembly 130, so that under the action of wind force, the flexible assembly 140 deforms first compared with the photovoltaic assembly 130 and / or the deformation amount of the flexible assembly 140 is greater than that of the photovoltaic assembly 130.

[0058] Referring to Figure 1 In an embodiment, the auxiliary surface 150 is arranged at the top edge of the photovoltaic assembly 130, and the auxiliary surface 150 is an arc surface protruding away from the ground. Specifically, the auxiliary surface 150 is arranged at the top edge of the photovoltaic assembly 130, that is, the auxiliary surface 150 and the photovoltaic plane 131 form an angle at the top edge of the photovoltaic assembly 130. The auxiliary surface 150 is an arc surface protruding away from the ground, that is, the auxiliary surface 150 as a whole is an inclined arch, and according to experiments, the cyclone is mainly formed below the auxiliary surface 150.

[0059] In another embodiment, referring to Figures 1 to 5The auxiliary surface 150 is arranged on the top edge of the photovoltaic assembly 130, and the auxiliary surface 150 is a plane, and the horizontal projection width of the flexible assembly 140 is greater than or equal to the horizontal projection width of the photovoltaic assembly 130. Specifically, the auxiliary surface 150 is an inclined plane, and the flexible assembly 140 is arranged as a whole in an inclined manner, and the angle between the top edge of the auxiliary surface 150 and the photovoltaic plane 131 is a1. The horizontal projection width of the flexible assembly 140 is greater than or equal to the horizontal projection width of the photovoltaic assembly 130, so as to ensure that the flexible assembly 140 has sufficient width to form a cyclone contact, so as to form sufficient force, and because the gap between the adjacent two rows of photovoltaic assemblies 130 is greater than the length of the photovoltaic assembly 130, there is sufficient gap to accommodate the installation of the flexible assembly 140.

[0060] Further, the vertical projection width of the flexible assembly 140 is greater than or equal to the vertical projection width of the photovoltaic assembly 130. Thus, the flexible assembly 140 has sufficient length to form a cyclone contact, so as to form sufficient force.

[0061] If the vertical projection width of the flexible assembly 140 is equal to the vertical projection width of the photovoltaic assembly 130, the angle between the auxiliary surface 150 and the photovoltaic assembly 130 is greater than 90°. In order to ensure the installation stability of the photovoltaic assembly 130, the inclination angle of the photovoltaic assembly 130 with respect to the horizontal direction is generally less than or equal to 45°, and the horizontal projection width of the flexible assembly 140 is greater than or equal to the horizontal projection width of the photovoltaic assembly 130, and the vertical projection width of the flexible assembly 140 is equal to the vertical projection width of the photovoltaic assembly 130, so the angle between the auxiliary surface 150 and the photovoltaic assembly 130 is necessarily greater than 90°, which can ensure that the upper portion and / or the lower portion of the auxiliary surface 150 generates a cyclone, so as to ensure that the photovoltaic assembly 130 can withstand the pre-tightening force, and improve the installation stability of the photovoltaic assembly 130. Of course, in other embodiments, the angle between the auxiliary surface 150 and the photovoltaic assembly 130 can also be greater than 90°.

[0062] If the vertical projection width of the flexible assembly 140 is greater than the vertical projection width of the photovoltaic assembly 130, in an embodiment, the angle between the line connecting the bottom edge of the auxiliary surface 150 and the bottom edge of the photovoltaic assembly 130 and the horizontal direction is less than or equal to 20°. As shown in FIG. 2B, the angle between the line connecting the bottom edge of the auxiliary surface 150 and the bottom edge of the photovoltaic assembly 130 and the horizontal direction is a2. Figure 4As shown, the angle between the line connecting the bottom edge of the auxiliary surface 150 and the bottom edge of the photovoltaic assembly 130 and the horizontal direction is a2. If a2 is greater than 20°, a2 is too large, the pulsation of the tension force provided by the auxiliary surface 150 is greater, which is unstable and is not conducive to adjusting the tension force of the photovoltaic rope 111. At this time, the cyclone is mainly formed on the upper part of the auxiliary surface 150 and away from the photovoltaic assembly 130, so that a greater pressure is generated on the end of the auxiliary surface 150 away from the photovoltaic assembly 130 and vertically upward, and the pressure on the end of the auxiliary surface 150 close to the photovoltaic assembly 130 is close to zero, thereby causing the flexible assembly 140 to rotate as a whole relative to the photovoltaic assembly 130 with the end close to the photovoltaic assembly 130 as the axis. Of course, in other embodiments, the angle between the line connecting the bottom edge of the auxiliary surface 150 and the bottom edge of the photovoltaic assembly 130 and the horizontal direction can also be greater than 20°.

[0063] In yet another embodiment, referring to Figure 5 , the auxiliary surface 150 is arranged at the bottom edge of the photovoltaic assembly 130. Specifically, the auxiliary surface 150 is arranged at the bottom edge of the photovoltaic assembly 130, that is, the auxiliary surface 150 and the photovoltaic plane 131 form an angle a3 at the bottom edge of the photovoltaic assembly 130. In this embodiment, the angle between the auxiliary surface 150 and the photovoltaic support 100 is less than or equal to 135°. If the angle between the auxiliary surface 150 and the photovoltaic support 100 is less than or equal to 135°, in the extreme state, the auxiliary surface 150 can be a vertical plane, and the photovoltaic plane 131 is an inclined plane with an inclination angle of 45°; or the auxiliary surface 150 and the photovoltaic plane 131 are both horizontal planes. At this time, the cyclone alternately occurs at the position between the auxiliary surface 150 and the photovoltaic plane 131, so that the tension force generated by the auxiliary surface 150 is greater than that of the photovoltaic plane 131, thereby causing the flexible assembly 140 to deform and deflect as a whole relative to the photovoltaic assembly 130, thereby improving the tension force of the photovoltaic support 100. Of course, in other embodiments, the angle between the auxiliary surface 150 and the photovoltaic support 100 can also be greater than 135°.

[0064] Compared with the flexible assembly 140 formed with one auxiliary surface 150, in another embodiment, referring to Figures 6 to 9 , the flexible assembly 140 is formed with a plurality of auxiliary surfaces 150, and the plurality of auxiliary surfaces 150 are arranged at an angle. Under the action of wind, cyclones are formed above and / or below at least one auxiliary surface 150, thereby changing the pressure difference above and below the auxiliary surface 150, so that the flexible assembly 140 deflects as a whole relative to the photovoltaic assembly 130, thereby deforming the auxiliary rope 112, and further tightening the photovoltaic rope 111, thereby improving the tension force of the photovoltaic support 100. As shown in Figure 6As shown, the plurality of auxiliary surfaces 150 are combined to form a large auxiliary surface 150, so that the overall flexible assembly 140 is wavy, and the cyclone of the auxiliary surface 150 is generated at the angle between the auxiliary surface 150 and the photovoltaic assembly 130, so that the flexible assembly 140 is deformed and deflected, thereby increasing the tension of the photovoltaic support 100.

[0065] Referring to Figure 7 In an embodiment, the plurality of auxiliary surfaces 150 are arranged on the top edge of the photovoltaic assembly 130, so that cyclones are formed between the plurality of auxiliary surfaces 150, thereby increasing the force on the auxiliary surfaces 150, so that the force on the auxiliary surfaces 150 is greater than the force on the photovoltaic surface 131, and the overall flexible assembly 140 is deformed and deflected relative to the photovoltaic assembly 130, thereby increasing the tension of the photovoltaic support 100.

Specifically, the plurality of auxiliary surfaces 150 are arranged on the top edge of the photovoltaic assembly 130, i.e., on the leeward side of the photovoltaic assembly 130, the photovoltaic surface 131, the first auxiliary surface 151, the second auxiliary surface 152, and the third auxiliary surface 153 are connected in sequence and arranged at an angle, the widths of the plurality of auxiliary surfaces 150 are substantially equal, and the widths of the plurality of auxiliary surfaces 150 are substantially equal to the width of the photovoltaic surface 131, and the angle of the plurality of auxiliary surfaces 150 and the angle of the photovoltaic surface 131 and the auxiliary surfaces are also substantially equal, so that the sum of the horizontal projection widths of the plurality of auxiliary surfaces 150 is three times the horizontal projection width of the photovoltaic assembly 130. Cyclones are formed at the angles of the photovoltaic surface 131, the first auxiliary surface 151, the second auxiliary surface 152, and the third auxiliary surface 153, thereby increasing the force on the auxiliary surfaces 150, so that the force on the auxiliary surfaces 150 is greater than the force on the photovoltaic surface 131, and the overall flexible assembly 140 is deformed and deflected relative to the photovoltaic assembly 130, thereby increasing the tension of the photovoltaic support 100.

[0070] The auxiliary cord 112 comprises a first auxiliary cord 115 and a second auxiliary cord 116, the first auxiliary cord 115 and the second auxiliary cord 116 are arranged along the width direction of the flexible assembly 140.

[0071] Specifically, the first photovoltaic cord 113 and the second photovoltaic cord 114 are arranged along the length direction of the photovoltaic assembly 130, and the first photovoltaic cord 113 and the second photovoltaic cord 114 are arranged close to the opposite sides of the photovoltaic assembly 130, thereby improving the installation stability of the photovoltaic assembly 130.

[0075] In another embodiment, referring to Figure 11The pulley block 120 includes a third fixed pulley 123 and a fourth fixed pulley 124, both of which are arranged at opposite ends of the photovoltaic assembly 130 and the flexible assembly 140. The third fixed pulley 123 is arranged at a side where the photovoltaic assembly 130 and the flexible assembly 140 are close to each other, and the fourth fixed pulley 124 is arranged at a side where the photovoltaic assembly 130 and the flexible assembly 140 are far away from each other. The photovoltaic rope 111 and the auxiliary rope 112 are wound around the third fixed pulley 123 and the fourth fixed pulley 124 respectively and connected to each other. Specifically, the two ends of the photovoltaic rope 111 are wound around the third fixed pulley 123 and the fourth fixed pulley 124 at opposite ends of the photovoltaic assembly 130 respectively, and then wound around the fourth fixed pulley 124 at the other end alternately, so as to complete the winding and fixing of the photovoltaic rope 111. The two ends of the auxiliary rope 112 are wound around the third fixed pulley 123 and the fourth fixed pulley 124 at opposite ends of the flexible assembly 140 respectively, and then wound around the fourth fixed pulley 124 at the other end alternately, so as to complete the winding and fixing of the auxiliary rope 112. The fourth fixed pulley 124 is a double-wheel fixed pulley, and the fourth fixed pulley 124 on the side where the photovoltaic rope 111 is located is a one-way fixed pulley, i.e., the fourth fixed pulley 123 on the side where the photovoltaic rope 111 is located can only rotate in the direction of tensioning the photovoltaic rope 111. The photovoltaic rope 111 and the auxiliary rope 112 are connected to each other. Under the action of wind, the flexible assembly 140 deforms or deflects, so that the auxiliary rope 112 is tensioned, the fourth fixed pulley 124 is rotated, and the auxiliary rope 112 is tensioned. Then, the auxiliary rope 112 provides tensioning force for the photovoltaic rope 111, the third fixed pulley 123 rotates in the direction of tensioning the photovoltaic rope 111, and the photovoltaic rope 111 is tightened.

[0076] Further, the pulley set 120 further comprises a fifth fixed pulley 125, a sixth fixed pulley 126 and a movable pulley 127, the fifth fixed pulley 125 is arranged at the end of the auxiliary rope 112, the sixth fixed pulley 126 is arranged at the end of the photovoltaic rope 111, the movable pulley 127 is arranged between the fifth fixed pulley 125 and the sixth fixed pulley 126, the fifth fixed pulley 125 is provided with a first hook 128, the movable pulley 127 is provided with a second hook 129, the end of the photovoltaic rope 111 is sequentially wound around the fourth fixed pulley 124, the fifth fixed pulley 125 and the movable pulley 127, and is fixed to the first hook 128, the end of the auxiliary rope 113 is sequentially wound around the fourth fixed pulley 124 and the sixth fixed pulley 126, and is fixed to the second hook 129. Specifically, under the action of wind, the flexible assembly 140 deforms or deflects, so that the auxiliary rope 112 is tensioned, the fourth fixed pulley 124 on the auxiliary rope 112 rotates, and the movable pulley 127 moves towards the fifth fixed pulley 125, so that the second hook 129 drives the photovoltaic rope 112 to be tensioned, so that the fourth fixed pulley 124 on the photovoltaic rope 111 deflects towards the direction of tensioning the photovoltaic rope 111, thereby tightening the photovoltaic rope 111. And because of the existence of the movable pulley 127, the flexible assembly 140 can pull the photovoltaic assembly 130 with relatively small force. For example, when the flexible assembly 140 is subjected to a force of 1 / 2F, the photovoltaic assembly 130 can be pulled to bear a force of F. Thus, the tensioning force of the photovoltaic assembly 130 is further increased.

[0077] In an embodiment, referring to Figures 10 to 12 The flexible assembly 140 comprises a flexible film 141 and a fixed frame 142 fixed to the periphery of the flexible film 141, the fixed frame 142 is mounted on the rope assembly 110, and the fixed frame 142 has a plurality of reinforcing ribs 143 arranged at intervals along the extension direction of the flexible film 141.

Thus, the flexible film 141 is fixed, and the possibility of curling is reduced. The installation and removal of the flexible film 141 are facilitated, and the flexible film 141 can be replaced in time when it is damaged. In addition, the fixed frame 142 has a plurality of reinforcing ribs 143 arranged at intervals along the extension direction of the flexible film 141. The plurality of reinforcing ribs 143 serve as the mounting framework of the flexible film 141, and further enhance the fixing stability of the flexible film 141.

[0080] Further, the adapter 145 comprises at least one adapter piece 148, and each adapter piece 148 connects an auxiliary surface 150, and adjacent two adapters 145 are connected through a rotating shaft. The plurality of adapter pieces 148 are sequentially connected, and the included angle between the plurality of adapter pieces 148 is adjustable, thereby making the adapter 145 further adapt to the shape of the flexible assembly 140, and when the shape of the flexible assembly 140 changes, the shape of the adapter 145 can be adjusted to reduce the replacement process of the adapter 145.
