DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, a large-span bracket for a photovoltaic power station includes a bracket body 1, a first mounting ring 2 is detachably sleeved on the outer side of the top of the bracket body 1, an adjusting screw rod 4 is detachably installed on the center point inside the bracket body 1, and a movable rod 5 is threadedly connected to one end of the adjusting screw rod 4, and a plurality of mounting grooves 6 are evenly arranged on the outer side of the movable rod 5. When the bracket body 1 is installed, the bracket body 1 is vertically installed at the specified position by the staff. At this time, the fastening bolts 9 are loosened, and the mounting block 7 is pulled to drive the arc bar 8 to disengage from the mounting groove 6, and then the movable rod 5 is rotated to move upward through the thread of the adjusting screw rod 4, and the movable rod 5 drives the limit ring 10 to drive the fixed head 11 to move upward, and the height of the movable rod 5 extending out of the bracket body 1 is adjusted according to the height of the crystalline silicon panel 19 to be installed on site. The bracket body 1 cooperates with the movable rod 5 to adapt to the crystalline silicon panel 19 with different installation height requirements, has a wider range of adaptability, is more practical, does not need to be customized separately, and saves procurement costs.

[0023] After the installation of the bracket body 1 is completed, another identical bracket body 1 and movable rod 5 are adjusted and installed according to the steps of adjusting the movable rod 5 above. Two identical bracket bodies 1 and movable rod 5 form a group, and then another group is installed symmetrically. The connecting cables 18 are pulled symmetrically on the fixed heads 11 at the tops of the movable rods 5 of the two groups, and the crystalline silicon plate 19 is installed on the connecting cables 18. Then, the anchor rod 17 is pulled to fix it on the ground on one side of the bracket body 1. The anchor rod 17 pulls the fixed cable 15 to drive the first installation ring 2, and the first installation ring 2 drives the bracket body 1, thereby installing the bracket body 1.

[0024] like Figure 1 and Figure 4 As shown, a limit assembly 3 is arranged on the outer side of the bottom end of the bracket body 1, and the limit assembly 3 includes a second mounting ring 12. The inner wall of the second mounting ring 12 is detachably mounted on the outer side of the bracket body 1. A notch is arranged on one side of the second mounting ring 12. The inner wall of the notch arranged on the second mounting ring 12 is symmetrically provided with a first receiving groove and a second receiving groove. Before transportation, the staff pulls the fixing sleeve 16 to drive the fixing cable 15. At the same time, the handle 20 is pulled to drive the arc plate 13 to compress the elastic rubber plate 14 in the first receiving groove of the second mounting ring 12, so that the fixing sleeve 16 drives the fixing cable 15 to be released. The arc plate 13 is placed in the notch of the second mounting ring 12, and the arc plate 13 is released. The arc plate 13 returns to its original position under the elastic force of the elastic rubber plate 14. The arc plate 13 limits the fixing sleeve 16. The cable 15 is designed as an integral part of the first mounting ring 2. Compared with assembling and installing the cable 15 with the bracket body 1 on site, it is more labor-saving, saves on-site installation time, and improves installation efficiency. During transportation, the fixed sleeve 16 drives the fixed cable 15 to be limited and stored in the notch of the second mounting ring 12. The fixed cable 15 is transported as an integrated part with the bracket body 1, which is convenient for the staff to place and is not easy to lose fragments.

[0025] How it works

[0026] It should be noted that the utility model is a large-span bracket for a photovoltaic power station. When in use, first pull the fixed sleeve 16 to drive the fixed cable 15, and the fixed cable 15 drives the anchor rod 17. At the same time, pull the handle 20 to drive the arc plate 13 to compress the elastic rubber plate 14 in the first receiving groove of the second mounting ring 12. The arc plate 13 no longer blocks the gap set in the second mounting ring 12. Then, the fixed sleeve 16 drives the fixed cable 15 to be placed in the gap of the second mounting ring 12, and the arc plate 13 is released. The arc plate 13 returns to its original position under the elastic force of the elastic rubber plate 14, and the arc plate 13 limits the fixed sleeve 16, thereby achieving the purpose of storing and limiting the fixed sleeve 16 and the fixed cable 15.

[0027] When the bracket body 1 is transported to the site and needs to be installed, the handle 20 is pulled again to drive the curved plate 13, and the fixed sleeve 16 is pulled to drive the fixed cable 15, and the fixed sleeve 16 and the fixed cable 15 are pulled out from the notch of the second mounting ring 12, and then the bracket body 1 is vertically installed at the specified position. At this time, the fastening bolt 9 is loosened, and the fastening bolt 9 is separated from the mounting block 7, and then the mounting block 7 is pulled to drive the curved bar 8 to separate from the inside of the mounting groove 6, and the curved bar 8 no longer limits the movable rod 5, and the movable rod 5 is rotated. The movable rod 5 moves upward under the action of the thread on the adjusting screw 4. The movable rod 5 drives the limit ring 10 to drive the fixed head 11 to move upward. The height of the movable rod 5 in the bracket body 1 is adjusted according to the height of the crystalline silicon board 19 to be installed on site. After determining the height, pull the mounting block 7 to drive the arc strip 8 to be installed to the movable rod 5 located at the top of the bracket body 1 at this time. The arc strip 8 is inserted into the mounting groove 6 opened on the movable rod 5 again, tighten the fastening bolts 9, and lock the symmetrically installed mounting blocks 7 on the outside of the movable rod 5 to adjust the extended height of the movable rod 5 in the bracket body 1 to adapt to the crystalline silicon boards 19 with different installation height requirements.

[0028] After the bracket main body 1 is installed, another identical bracket main body 1 is installed according to the above steps. The two bracket main bodies 1 form a group. After installing one group of bracket main bodies 1, symmetrically install another group of bracket main bodies 1. Symmetrically pull the connecting cables 18 on the fixed heads 11 on the two groups of bracket main bodies 1, install the crystalline silicon plate 19 on the connecting cables 18, and then pull the anchor rod 17. The anchor rod 17 drives the fixed cable 15 to fix the anchor rod 17 on the ground on one side of the bracket main body 1. The anchor rod 17 pulls the fixed cable 15 to drive the first mounting ring 2, and the first mounting ring 2 drives the bracket main body 1, so as to achieve the purpose of sharing the force of the bracket main body 1 and fixing the bracket main body 1.
