A first connecting rope is movably connected between two connecting frames on the same horizontal line. Through the operation of the first motor, the first motor can drive the first threaded column to rotate through the driving gear and the driven gear. When the first threaded column rotates, the telescopic column in the support column is lifted and lowered through the first moving block and the first threaded groove. When the telescopic column on one side is lowered, the telescopic column on the other side does not move and the height does not change. In this way, the first connecting rope will be inclined, and the inclination angle of the photovoltaic panel will also be changed. Thus, the inclination angle of the photovoltaic panel can be changed.

The base (411) has an assembly groove (741) inside one end. The mounting bracket (417) is slidably disposed in the assembly groove (741). The side of the mounting bracket (417) away from the adjusting wheel (412) is assembled and connected to the inner wall of the base (411) by a fifth spring (743). An insert (742) is slidably passed through the base (411) on the side of the mounting bracket (417) away from the adjusting wheel (412). The insert (742) has a structure that is wider at the top and narrower at the bottom and is located between the mounting bracket (417) and the assembly groove (741). The disassembly structure of the first ratchet disc (611) and the first pawl (612) is the same as that of the second ratchet disc (712) and the second pawl (713). A bracket (751) is provided below the second pawl (713). The bracket (751) is slidably connected to the inner wall of the base (411). A third gear (752) is rotatably provided inside the base (411) on one side of the bracket (751) and meshes with the side of the bracket (751). A disassembly strip (753) is provided on the upper outside of the base (411). The lower end of the disassembly strip (753) is slidably provided inside the base (411) and one side meshes with the third gear (752).

2. The cable tension adjustment device for a flexible photovoltaic support according to claim 1, characterized in that, The main cable (2) is wound around the one-way wheel (312) for no less than ten turns. The top seat (311) is provided with positioning components (5) at the feed end and the discharge end. The positioning component (5) includes a fixed tube (511), a push block (512) and a first spring (513). The push block (512) is provided in multiple ways and is rotatably disposed in the fixed tube (511) at one end away from the base (411). The main cable (2) slides through the multiple push blocks (512). The other end of the push block (512) is assembled and connected to the inner wall of the fixed tube (511) through the first spring (513).

3. The cable tension adjustment device for a flexible photovoltaic support according to claim 2, characterized in that, The fixed tube (511) is composed of two half tubes (521). The two half tubes (521) are rotatably connected on one side and assembled and connected on the other side by a first bolt (522). A fixing frame (523) is provided on the top seat (311). The fixed tube (511) is set in the fixing frame (523) and fixed by a second bolt (524).

4. The cable tension adjustment device for a flexible photovoltaic support according to claim 1, characterized in that, The outer wall of the base (411) is provided with a protective film (761), and the disassembly strip (753) is located inside the protective film (761). The disassembly strip (753) is set on the outer end of the base (411) and is assembled and connected to the base (411) by a fourth spring (762).
