In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] Flexible photovoltaic brackets have high site applicability due to their large span and high clearance, and have an increasingly wide range of application scenarios. The steel cable will produce a certain degree of deflection when carrying and fixing photovoltaic modules. Specifically, the steel cable will deform and bend in the vertical direction under the action of the load, and this deformation and bending is the deflection. The deflection will affect the safety of the flexible photovoltaic bracket, and affect the installation angle of the photovoltaic module on the steel cable, and then affect the relative angle between the photovoltaic module and the sunlight, and affect the power generation efficiency of the photovoltaic module. Therefore, it is necessary to detect the deflection of the steel cable.

[0051] In order to detect the deflection of the steel cable 200, Figure 1 to Figure 4As shown, this embodiment provides a flexible photovoltaic support deflection detection device 100. The flexible photovoltaic support deflection detection device 100 includes a first distance detection component 110, a second distance detection component 120 and a mounting frame 130, wherein the first distance detection component 110 includes a first distance detection body 111 and a first connecting member 112 connected, the first connecting member 112 can extend outward, and the first distance detection body 111 is configured to detect the extension distance of the first connecting member 112, the second distance detection component 120 includes a second distance detection body 121 and a second connecting member 122 connected, the second connecting member 122 can extend outward, and the second distance detection body 121 is configured to detect the extension distance of the second connecting member 122, the first distance detection body 111 and the second distance detection body 121 are spaced apart on the mounting frame 130, the connection line between the first distance detection body 111 and the second distance detection body 121 is parallel to the horizontal plane, and the output ends of the first connecting member 112 and the second connecting member 122 are both connected and fixed at the same position of the steel cable 200.

[0052] The flexible photovoltaic support deflection detection device 100 is provided with a mounting frame 130, and a first distance detection body 111 in a first distance detection component 110 and a second distance detection body 121 in a second distance detection component 120 are spaced apart on the first mounting frame 130, so that the connection line between the first distance detection body 111 and the second distance detection body 121 is parallel to the horizontal plane, and the output end of the first connecting member 112 in the first distance detection body 111 connected to the first distance detection body 111 is connected to the steel cable 200, and the output end of the second connecting member 122 in the second distance detection component 120 connected to the second distance detection body 121 is connected to the steel cable 200, so that the output end of the first connecting member 112 The output end of the first connecting member 111 and the output end of the second connecting member 122 are simultaneously connected and fixed at the same position of the steel cable 200, and the first distance detecting body 111 is used to detect the extension distance of the first connecting member 112, and the second distance detecting body 121 is used to detect the extension distance of the second connecting member 122. Combined with the interval distance between the first distance detecting body 111 and the second distance detecting body 121, the vertical distance between the steel cable 200 and the first distance detecting body 111 or the vertical distance between the steel cable 200 and the second distance detecting body 121 can be obtained, so as to obtain the vertical distance of the line connecting the steel cable 200 and the first distance detecting body 111 and the second distance detecting body 121 before the photovoltaic module 400 is laid on the steel cable 200, that is, the deflection judgment benchmark of the steel cable 200. When the steel cable 200 produces vertical deformation and lateral displacement, the extension distance of the first connecting member 112 and the extension distance of the second connecting member 122 will change, but the interval distance between the first distance detection body 111 and the second distance detection body 121 will not change. By using the cosine theorem and trigonometric functions, it can be obtained that when the position where the steel cable 200 is connected and fixed to the first connecting member 112 and the second connecting member 122 produces vertical deformation and lateral displacement, the vertical distance between it and the connecting line of the first distance detection body 111 and the second distance detection body 121 can be obtained. According to the difference between the deflection judgment benchmark of the steel cable 200 and the vertical distance after the steel cable 200 produces vertical deformation and lateral displacement, the specific deflection value of the steel cable 200 is obtained, with high detection accuracy, which effectively improves the safety of use of the flexible photovoltaic bracket and the power generation efficiency of the photovoltaic component 400 fixed on the steel cable 200.

[0053] In order to further facilitate the understanding of the detection principle of the flexible photovoltaic support deflection detection device 100 provided in this embodiment, as shown in FIG. Figure 2 to Figure 4 As shown, the distance between the output end of the first connecting member 112 and the first distance detecting body 111 is L1, the extension distance between the output end of the second connecting member 122 and the second distance detecting body 121 is L2, and the extension distance between the first distance detecting body 111 and the second distance detecting body 121 is L3. According to the cosine theorem The angle θ1 between the first connecting member 112 and the line connecting the first distance detecting body 111 and the second distance detecting body 121 can be obtained, and then the vertical distance (L1*sinθ1) of the first connecting member 112 relative to the line connecting the first distance detecting body 111 and the second distance detecting body 121 can be obtained, or according to the cosine theorem The angle β1 between the second connecting member 122 and the line connecting the first distance detecting body 111 and the second distance detecting body 121 can be obtained, and then the vertical distance (L2*sinβ1) of the second connecting member 122 relative to the flexible bracket can be obtained.

[0054] When the steel cable 200 is vertically deformed and laterally offset, the extension distance between the output end of the first connecting member 112 and the first distance detection body 111 is L1', the extension distance between the output end of the second connecting member 122 and the second distance detection body 121 is L2', and the distance between the first distance detection body 111 and the second distance detection body 121 is still L3. According to the trigonometric function The angle θ2 between the line connecting the first connecting member 112 and the second distance detecting body 121 can be obtained, and then the vertical distance (L1'*sinθ2) of the first connecting member 112 relative to the line connecting the first distance detecting body 111 and the second distance detecting body 121 can be obtained, or according to the trigonometric function The angle β2 between the second connecting member 122 and the line connecting the first distance detecting body 111 and the second distance detecting body 121 can be obtained, and then the vertical distance (L2'*sinβ2) of the second connecting member 122 relative to the line connecting the first distance detecting body 111 and the second distance detecting body 121 can be obtained;

[0055] The actual vertical deflection value can be obtained according to L1*sinθ1-L1'*sinθ2, or the actual vertical deflection value can be obtained according to L2*sinβ1-L2'*sinβ2, thereby improving the detection accuracy of the deflection of the steel cable 200, effectively improving the safety of the use of the flexible photovoltaic bracket and the power generation efficiency of the photovoltaic component 400 fixed on the steel cable 200.

[0056] It should be noted that, in this embodiment, the first distance detection component 110 and the second distance detection component 120 are both draw-wire displacement sensors. The specific structure and working principle of the draw-wire displacement distance sensor belong to the prior art and will not be described in detail here.

[0057] It can be understood that the mounting frame 130 can be any placement platform with a supporting function, and it only needs to ensure the stable support of the first distance detection body 111 and the second distance detection body 121. In this embodiment, the mounting frame 130 includes a mounting column 131 and a mounting beam 132, wherein the mounting beam 132 extends in the horizontal direction, and the first distance detection body 111 and the second distance detection body 121 are spaced apart on the mounting beam 132. By splitting the mounting frame 130 into the mutually connected mounting columns 131 and the mounting beam 132, the mounting beam 132 is extended in the horizontal direction, and the first distance detection body 111 and the second distance detection body 121 are spaced apart on the mounting beam 132, it is convenient to measure the spacing distance between the first distance detection body 111 and the second distance detection body 121, and then it is convenient to measure the subsequent deflection of the steel cable 200. It should be noted that in this embodiment, the spacing distance between the first distance detection body 111 and the second distance detection body 121 is between 800mm and 1200mm. In other embodiments, the spacing distance between the first distance detection body 111 and the second distance detection body 121 may also be adjusted according to actual needs, which is not specifically limited in this embodiment.

[0058] To further improve the detection efficiency, the angle between any one of the first connection member 112 and the second connection member 122 and the line connecting the first distance detection body 111 and the second distance detection body 121 is a right angle. By making the angle between any one of the first connection member 112 and the second connection member 122 and the line connecting the first distance detection body 111 and the second distance detection body 121 a right angle, the extension distance of the first connection member 112 detected by the first distance detection body 111 can be the vertical distance of the line connecting the steel cable 200 and the first distance detection body 111 and the second distance detection body 121, or the extension distance of the second connection member 122 detected by the second distance detection body 121 can be the vertical distance of the line connecting the steel cable 200 and the first distance detection body 111 and the second distance detection body 121, thereby simplifying the calculation steps.

[0059] It should be noted that, in this embodiment, Figure 2 As shown, the angle between the first connecting member 112 and the line connecting the first distance detecting body 111 and the second distance detecting body 121 is a right angle. In other embodiments, the angle between the second connecting member 122 and the line connecting the first distance detecting body 111 and the second distance detecting body 121 can also be a right angle, which is not specifically limited in this embodiment.

By providing the connection structure 140 that is simultaneously connected to the steel cable 200 and the output end of the first connector 112 and the output end of the second connector 122, it is possible to ensure that the output ends of the first connector 112 and the second connector 122 are stably connected and fixed to the steel cable 200, thereby ensuring the normal operation of the flexible photovoltaic support deflection detection device 100.

[0061] Specifically, the connecting structure 140 includes a first fastening member 141, a second fastening member 142 and a locking member 143, wherein the first fastening member 141 and the second fastening member 142 are fastened to each other and are jointly sleeved and fixed on the outer periphery of the steel cable 200, and the locking member 143 is configured to lock and fasten the first fastening member 141 and the second fastening member 142 together, and the output ends of the first connecting member 112 or the second connecting member 122 are both connected and fixed to the locking member 143. By providing the first fastening member 141 and the second fastening member 142 that are fastened to each other, they can be sleeved on the outer periphery of the steel cable 200. By using the locking member 143 to lock the first fastening member 141 and the second fastening member 142 that are fastened together, the first fastening member 141 and the second fastening member 142 can be stably fixed to the steel cable 200. By connecting and fixing the output end of the first connecting member 112 or the output end of the second connecting member 122 to the locking member 143, the connection and fixation of the first connecting member 112 and the second connecting member 122 to the steel cable 200 are achieved.

It should be noted that in this embodiment, two locking members 143 are provided in the connection structure 140, and the two locking members 143 are arranged opposite to each other along the peripheral edges of the first fastening member 141 and the second fastening member 142 that are buckled together. The output end of the first connector 112 is connected to one locking member 143, and the output end of the second connector 122 is connected to the other locking member 143.
