DETAILED DESCRIPTION

[0026] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] As shown in Figures 1 to 7 The utility model provides a steel cable photovoltaic support, including the bottom plate 1, the bottom plate 1 has three groups, the top of three groups bottom plate 1 all are fixedly installed with stand 2, and the top of left and right two side stands 2 is provided with fixed frame 3, and is provided with connecting frame 4 between two groups fixed frame 3;

[0028] Two groups of steel cable 5 are provided between fixed frame 3 and connecting frame 4, the left side fixed mounting of fixed frame 3 has first guide pulley 6, and the below fixed mounting of first guide pulley 6 has second guide pulley 7, and the middle part fixed mounting of fixed frame 3 has fixed cylinder 8, and the inside rotation mounting of fixed cylinder 8 has winding rod 9, and one end of steel cable 5 and connecting frame 4 fixed connection, and the other end of steel cable 5 penetrates fixed frame 3, and steel cable 5 passes through the above of first guide pulley 6 and the below of second guide pulley 7 and and winding rod 9 fixed connection, and the outer wall fixed mounting of fixed cylinder 8 has fixed shell 10, and the inside rotation mounting of fixed shell 10 has ratchet wheel 11, and one end of ratchet wheel 11 and winding rod 9 fixed connection, and the outer wall rotation mounting of fixed shell 10 has control rod 15, and one end of control rod 15 and ratchet wheel 11 fixed connection.

[0029] When the photovoltaic panel needs to be laid, the staff first installs the device. After installation is complete, if the height of the fixing frame 3 and the connecting frame 4 needs to be adjusted according to the terrain of the photovoltaic panel laying, the staff can rotate the rotating disc 21. The rotation of the rotating disc 21 drives the rotation of the worm 20. Further, the transmission connection between the worm 20 and the worm gear 18 makes the worm gear 18 rotate. The rotation of the worm gear 18 drives the rotation of the lead screw 17. The rotation of the lead screw 17 drives the displacement of the extension column 16 along the stand 2. Further, the extension column 16 drives the lifting of the fixing frame 3 and the connecting frame 4. The staff can adjust the inclination of the steel cable 5 according to the ups and downs of the terrain. After adjustment is complete, the staff installs the photovoltaic panel on the top of the steel cable 5, and the work is completed. After the photovoltaic panel is used for a long time, the steel cable 5 will loosen, further causing the photovoltaic panel to shake. At this time, the maintenance personnel can rotate the control rod 15. At this time, due to the one-way transmission characteristics of the ratchet 11, and the elastic potential of the leaf spring 13 and the ratchet 11 are in mutual abutment through the brake block 12, the control rod 15 can only drive the ratchet 11 to rotate in one direction. The rotation of the ratchet 11 drives the rotation of the winding rod 9. Further, the winding rod 9 pulls the steel cable 5 on both sides to be wound on the outer wall of the winding rod 9. At this time, the steel cable 5 will displace along the first guide wheel 6 and the second guide wheel 7. When the staff stops rotating the control rod 15, the brake block 12 will prevent the reverse rotation of the ratchet 11, and the locking is completed. If the tension of the steel cable 5 needs to be temporarily loosened, the staff can rotate the knob 14 to release the brake relationship between the knob 14 and the ratchet 11. At this time, the winding rod 9 will reverse to make the steel cable 5 rebound, and the winding rod 9 will stop rotating when the steel cable 5 rebounds to the maximum value. Further, the tension adjustment of the steel cable 5 is realized. It is worth noting that the steel cable 5 is relatively hard, so the rotation amplitude of the winding rod 9 is small when the winding rod 9 is tensioned, and it will not output a large amplitude of tension adjustment.

[0030] By rotating the control rod 15, the winding rod 9 will pull the steel cable 5 on both sides to be wound on the outer wall of the winding rod 9. Further, the winding rod 9 will wind the steel cable 5 to make the steel cable 5 tight. By rotating the knob 14, the winding rod 9 will reverse, and further the steel cable 5 will rebound to make the steel cable 5 loose. Compared with the traditional device, the device can adjust the tension of the steel cable 5 by rotating the control rod 15 when the photovoltaic panel is normally used. After adjustment is complete, the ratchet 11 will be locked by the brake block 12 to complete the fixation, effectively improving the efficiency of the tension adjustment and reducing the work burden.

[0031] Among them, the extension column 16 is movably installed in the inside of the stand 2. The lead screw 17 is rotatably installed in the inside of the stand 2. The extension column 16 and the lead screw 17 are threadedly sleeved. The worm gear 18 is rotatably installed in the inside of the stand 2. The worm gear 18 and the lead screw 17 are fixedly connected.

[0032] The rotation of the worm gear 18 drives the screw rod 17 to rotate, and the rotation of the screw rod 17 drives the extension column 16 threaded with the screw rod 17 to displace upward along the stand 2, and further drives the fixed frame 3 and the connecting frame 4 to be lifted, so that the worker can adjust the inclination of the steel cable 5 according to the ups and downs of the terrain.

[0033] The rotation of the rotating disc 21 drives the worm 20 to rotate, and further drives the worm gear 18 to rotate, and further drives the screw rod 17 to drive the extension column 16 threaded with the screw rod 17 to displace upward along the stand 2, so as to adjust the height of the fixed frame 3 and the connecting frame 4. Compared with the traditional device, the device can adjust the height of the fixed frame 3 and the connecting frame 4 by rotating the rotating disc 21 when laying the photovoltaic support, so that the worker can adjust the inclination of the steel cable 5 according to the ups and downs of the terrain, thereby improving the work efficiency and reducing the work burden.

[0034] The inside of the fixed shell 10 is rotatably provided with a brake block 12, one end of the brake block 12 is elastically connected with the fixed shell 10 through a leaf spring 13, and the other end of the brake block 12 abuts against the ratchet wheel 11.

[0035] Due to the one-way transmission characteristic of the ratchet wheel 11, and the brake block 12 abuts against the ratchet wheel 11 through the elastic potential of the leaf spring 13, the control rod 15 can only drive the ratchet wheel 11 to rotate in one direction.

[0036] One end of the steel cable 5 penetrates into the inside of the fixed cylinder 8, and the steel cable 5 is cross-installed on the outer wall of the winding rod 9.

[0037] The cross arrangement of the steel cable 5 enables the winding rod 9 to wind the two groups of steel cables 5.

[0038] The outer wall of the fixed frame 3 and the connecting frame 4 is fixedly provided with a steel cable connecting piece 22, and the steel cable 5 is arranged in the steel cable connecting piece 22.

[0039] The arrangement of the steel cable connecting piece 22 protects the connection between the steel cable 5 and the fixed frame 3 and the connecting frame 4, and limits the position of the steel cable 5.

[0040] The outer wall of the stand 2 is fixedly provided with an outer shell 19, the inside of the outer shell 19 is rotatably provided with a worm 20, and the worm 20 is in transmission connection with the worm gear 18.

[0041] The outer wall of the stand 2 is rotatably provided with a rotating disc 21, and one end of the rotating disc 21 is fixedly connected with the worm 20.

[0042] The worker can rotate the rotating disc 21, the rotation of the rotating disc 21 drives the worm 20 to rotate, and further the worm 20 is in transmission connection with the worm gear 18, so as to drive the worm gear 18 to rotate.

[0043] The top of the left and right extension columns 16 is fixedly installed with a fixed frame 3, and the top of the middle extension column 16 is fixedly installed with a connecting frame 4.
