Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic power generation. More specifically, this invention relates to a flexible photovoltaic support structure suitable for sloping roofs. Background Technology

[0002] When installing photovoltaic panels on a sloping roof using flexible supports, it is inconvenient for workers to move around and carry out the work. Therefore, the work platform is often built at the top beam of the highest point of the roof. The two ends of the steel cable are fixed to the top beam and the eaves respectively, keeping the steel cable perpendicular to the top beam. All connecting blocks are pre-fitted onto the outside of the steel cable and are concentrated above the work platform.

[0003] During construction, workers stand on a workbench and place the photovoltaic panel above two steel cables. Four connecting blocks closest to the eaves are fixed to the four corners of the photovoltaic panel, allowing it to straddle the cables. The panel is then manually pushed along the cables towards the eaves, creating space above the workbench for the next panel. The second panel is installed in the same way, and then manually pushed along the cables towards the eaves, pushing the first panel and creating space above the workbench for the next panel. This process is repeated until each panel is installed and positioned. However, this process creates pressure between adjacent panels, and this pressure increases significantly with the number of panels pushed, potentially impacting the panel's structure. Summary of the Invention

[0004] To overcome the drawback that when moving photovoltaic panels, pressure is generated between adjacent photovoltaic panels, and this pressure increases significantly with the number of photovoltaic panels being moved, thereby affecting the structure of the photovoltaic panels, the present invention provides a flexible photovoltaic support suitable for sloping roofs.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1: A flexible photovoltaic support system suitable for sloping roofs, such as... Figures 1-8 As shown, it includes an even number of steel cables 1, each of which is provided with several fixing blocks 2; it also includes: Fixing block 2 3, one fixing block 2 3 is fixedly connected to each of the fixing blocks 1, and the fixing block 2 3 is in contact with the corresponding steel cable 1; Several fixing blocks 3 4 are provided on each of the steel cables 1, and each fixing block 3 4 is in contact with the corresponding fixing block 1 2; Fixed block 4 5, one fixed block 4 5 is fixedly connected to each of the fixed blocks 3 4, and the fixed block 4 5 is in contact with the corresponding steel cable 1; The long rod 6 is rotatably connected to each of the three fixed blocks 4; A fixing component is connected to the steel cable 1 to fix the end of the steel cable 1.

[0024] The fixing assembly includes a connecting block 201, a screw 202, and a nut 203; each end of each steel cable 1 is connected to a connecting block 201, and the connecting block 201 is made of alloy material; each connecting block 201 is provided with two screws 202; each screw 202 is threaded with a nut 203, and the nut 203 contacts the corresponding connecting block 201.

[0025] First, the workbench is manually erected on the roof beam. The four right-hand screws 202 are welded to the roof beam, and the four left-hand screws 202 are welded to the roof eaves. The nuts 203 are tightened to fix the steel cable 1 to the roof. At this point, the steel cable 1 is perpendicular to the roof beam and parallel to the roof slope. Then, fixing blocks 1 (2), 2 (3), 3 (4), and 4 (5) are placed outside the steel cable 1, and fixing blocks 1 (2) and 2 (3) are secured together with bolts. Fixed blocks 3 (4) and 4 (5) are secured together with bolts, ensuring that all fixed blocks 1 (2), 2 (3), 3 (4), and 4 (5) are positioned above the workbench. Each pair of adjacent fixed blocks 1 (2) is grouped together, and each pair of adjacent fixed blocks 3 (4) is grouped together. Counting is performed on each group of fixed blocks 1 (2) and each group of fixed blocks 3 (4) from left to right (from the eaves to the roof). Then, the first group of fixed blocks 1 (2) is moved to the left (towards the eaves), and then the next group... Rotate the long rod 6 ninety degrees so that its end contacts the first set of fixing blocks 1-2. Then, fix the end of the long rod 6 to the first set of fixing blocks 1-2 with bolts. Adjust the angles of fixing blocks 1-2 and 3-4 so that their upper surfaces are parallel to the roof slope. Place the first photovoltaic panel 7 on top of the first set of fixing blocks 1-2 and 3-4, and fix its four corners to the first set of fixing blocks 1-2 and 3-4 respectively. This completes the installation of the first photovoltaic panel 7. Then, manually push the first photovoltaic panel 7 to the left (towards the eaves) to create installation space above the workbench. Repeat the above steps to install the second photovoltaic panel 7. Push the second photovoltaic panel 7 to the left (towards the eaves). The second photovoltaic panel 7 moves the second set of fixing blocks 1-2 and 3-4 so that the second set of fixing blocks 1-2 contacts the first set of fixing blocks 3-4. At this point, the positions of fixing blocks 1-2, fixing blocks 3-4, and the long rod 6 are as follows: Figure 7 As shown, the second photovoltaic panel 7 is manually pushed, causing the second set of fixing blocks 1-2 to push the first set of fixing blocks 3-4. The first set of fixing blocks 3-4 applies a pushing force to the first set of fixing blocks 1-2 through the long rod 6 on it. Then, the first set of fixing blocks 1-2 and the first set of fixing blocks 3-4 drive the first photovoltaic panel 7 to move to the left. During this process, the pushing force acts on the long rod 6, and the photovoltaic panel 7 will not be subjected to compressive force. That is, the long rod 6 protects the photovoltaic panel 7, avoiding structural damage caused by excessive compressive force on the photovoltaic panel 7. Furthermore, by making the long rod 6 rotatable, all fixing blocks 1-2 and fixing blocks 3-4 can be gathered above the workbench to achieve convenient installation operation.

[0026] After fixing the end of the long rod 6 to the fixing block 2, the operator first aligns the two left corners of the photovoltaic panel 7 with the fixing holes of the two fixing blocks 2. Then, the bolts are screwed into the fixing holes to fix the two left corners of the photovoltaic panel 7 to the two fixing blocks 2. At this time, the long rod 6 positions the fixing block 4, so that the fixing holes on the two fixing blocks 4 automatically align with the fixing holes on the two right corners of the photovoltaic panel 7. At this time, the operator does not need to align the fixing blocks 4 and the photovoltaic panel 7. Then, the bolts fix the two right corners of the photovoltaic panel 7 to the two fixing blocks 4, completing the installation of the photovoltaic panel 7. In use, the long rod 6, which is used to protect the photovoltaic panel 7, is also used to position the fixing blocks 4. The operator does not need to align the fixing blocks 4 and the photovoltaic panel 7 manually, which helps to improve installation efficiency.

[0027] It also includes cylinders 204; two cylinders 204 are welded on each fixing block 3 4, and the cylinders 204 are plugged into and connected to the corresponding fixing block 1 2, and the corresponding fixing block 1 2 and fixing block 3 4 are fixed by the cylinders 204.

[0028] Before installing the photovoltaic panel 7, the operator simultaneously moves the first set of fixing blocks 1-2 and 3-4 to the left to create installation space. At this time, the gravity of the naturally suspended long rod 6 acts on fixing block 3-4, causing its upper side to automatically parallel to the roof slope. Fixing block 3-4, through the cylinder 204, moves fixing block 1-2, thus causing its upper side to automatically parallel to the roof slope. Therefore, at this point, the upper sides of both fixing blocks 1-2 and 3-4 are parallel to the roof slope, allowing the operator to directly attach the lower side of the photovoltaic panel 7 to the upper sides of fixing blocks 1-2 and 3-4 without manually adjusting their angles. This fixes the two left corners of the photovoltaic panel 7 to the first set of fixing blocks 1-2. Then, the first set of fixing blocks 3 and 4 are moved to the right. Fixing blocks 3 and 4 move the cylinder 204 away from fixing blocks 1 and 2, so that fixing blocks 3 and 4 are moved to the right side of the photovoltaic panel 7. Then, the long rod 6 is rotated 90 degrees and the end of the long rod 6 is fixed to the first set of fixing blocks 1 and 2 with bolts. After fixing blocks 3 and 4 are positioned by the long rod 6, the two right corners of the photovoltaic panel 7 are fixed to the first set of fixing blocks 3 and 4, and the installation of the photovoltaic panel 7 is completed. When in use, the long rod 6 is used to protect the photovoltaic panel 7 and also to make the upper sides of fixing blocks 1 and 2 and fixing blocks 3 and 4 automatically parallel to the roof slope. When installing the photovoltaic panel 7, there is no need to manually adjust the angle of fixing blocks 1 and 2 and fixing blocks 3 and 4, which helps to improve the installation efficiency.

[0029] It also includes auxiliary components, including connecting block 205, roller 206 and spring 207; each fixed block 3 4 is slidably connected to a connecting block 205; each connecting block 205 is rotatably connected to a roller 206; each fixed block 3 4 is fixedly connected to a corresponding connecting block 205 and a spring 207.

[0030] When the fixing block 34 is manually slid against the lower side of the photovoltaic panel 7, relative sliding between the fixing block 34 and the lower side of the photovoltaic panel 7 poses a risk of scratching. Therefore, an auxiliary component is installed on the fixing block 34. After fixing the two left corners of the photovoltaic panel 7 to the first fixing block 12, the lower side of the photovoltaic panel 7 contacts the roller 206. Then, the fixing block 34 is manually moved to the right. The fixing block 34 drives the connecting block 205 and the roller 206 to move to the right, causing the roller 206 to roll to the right on the lower side of the photovoltaic panel 7, thus preventing the fixing block 34 from scratching the lower side of the photovoltaic panel 7. Regarding the side issue, when fixing block 3 4 is fixed to photovoltaic panel 7 with bolts, the tightening force of the bolts makes fixing block 3 4 fit tightly against photovoltaic panel 7, thereby causing photovoltaic panel 7 to push roller 206 downward. Roller 206 drives connecting block 2 205 downward and compresses spring 207, thereby causing roller 206 to retract into the inside of fixing block 3 4, so that photovoltaic panel 7 can be properly installed and fixed. In use, the cooperation of connecting block 2 205, roller 206 and spring 207 avoids the problem of fixing block 3 4 scratching the lower side of photovoltaic panel 7.

[0031] It also includes a lead screw 208; each connecting block 205 is rotatably connected to a lead screw 208, and the lead screw 208 is screwed to the corresponding fixed block 3 4, so that the connecting block 205 can be moved by the lead screw 208.

[0032] After the photovoltaic panel 7 is installed, the compressed spring 207 will exert an upward thrust on the roller 206, causing the roller 206 to exert a squeezing force on the lower side of the photovoltaic panel 7. Over time, this can easily damage the lower side of the photovoltaic panel 7. Therefore, a lead screw 208 is installed on the connecting block 205. After the photovoltaic panel 7 is fixed on the fixing block 3 4, the lead screw 208 is manually rotated by a four-corner wrench. The lead screw 208 drives the connecting block 205 downward, and the connecting block 205 drives the roller 206 downward away from the photovoltaic panel 7, thus avoiding the problem of damage. During use, the lead screw 208 drives the roller 206 away from the photovoltaic panel 7, preventing the roller 206 from damaging the lower side of the photovoltaic panel 7.

[0033] Example 2, based on Example 1, such as Figure 8 As shown, it also includes an adjustment assembly, which includes a connecting block 3 209, a lead screw 2010, and a connecting block 4 2011; each end of each steel cable 1 is fixedly connected to a connecting block 3 209, which is made of alloy material; each connecting block 3 209 is rotatably connected to a lead screw 2010, which drives the connecting block 3 209 to move; each lead screw 2010 is screwed to a connecting block 4 2011, which is connected to the corresponding connecting block 1 201, and is made of alloy material.

[0034] It also includes a dial wheel 2012; each lead screw 2010 is fixedly connected to a dial wheel 2012, which drives the lead screw 2010 to rotate, making it more convenient to apply force.

[0035] It also includes a lead screw 3 2013; a connecting block 1 201 and a connecting block 4 2011 are slidably connected; each connecting block 1 201 is rotatably connected to a lead screw 3 2013, and the lead screw 3 2013 is screwed to the corresponding connecting block 4 2011, so that the connecting block 4 2011 can be moved by the lead screw 3 2013.

[0036] It also includes a dial wheel 2014; each lead screw 3 2013 is fixedly connected to a dial wheel 2014, which drives the lead screw 3 2013 to rotate, making it more convenient to apply force.

[0037] Steel cable 1 is made of rust-resistant material to prevent corrosion and extend its service life.

[0038] After the steel cable 1 is fixed to the roof, the operator manually drives the lead screw 2010 to rotate through the dial 1 2012, thereby causing the lead screw 2010 to move linearly relative to the connecting block 4 2011. The lead screw 2010 drives the connecting block 3 209 to move, and the connecting block 3 209 drives the end of the steel cable 1 to move, thereby adjusting the tension of the steel cable 1.

[0039] After the steel cable 1 is fixed to the roof, the operator manually drives the lead screw 2013 to rotate through the dial 2014. The lead screw 2013 drives the connecting block 4 2011 to move up and down on the connecting block 1 201. The connecting block 4 2011 drives the parts on it to move up and down, thereby adjusting the height position of the two ends of the steel cable 1 so that the steel cable 1 is parallel to the roof slope.
