Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and in particular relates to a foldable quick-installation bracket for a solar photovoltaic panel. Background Art

[0002] Photovoltaic power generation (solar power generation) is a technology that uses the photovoltaic effect of semiconductor materials to directly convert solar energy into electrical energy. Its core background technologies cover multiple fields such as materials science, semiconductor physics, power electronics and system integration. In addition to power generation equipment, the mounting frame for installing power generation equipment also plays a vital role. The solar photovoltaic panel mounting bracket is an important part of the photovoltaic system. Its design, selection and installation directly affect the power generation efficiency, system stability and service life. There are many types of solar photovoltaic panels, which are mainly divided into RV roof brackets, ground brackets and special scenario brackets according to the application scenarios. Among them, special scenario brackets are the least used due to the special structure of their structure, and ground brackets mostly require large unmanned flat land, so their application is also relatively rare. RV roof photovoltaic panel mounting brackets are widely used on RVs, but the RV roof solar brackets seen on RV roofs everywhere still need improvement.

[0003] The existing bracket structure takes safety requirements into consideration and often customizes adaptive structural solutions according to common RV roof environments and puts them into production to ensure the safe and stable operation of the bracket, which will reduce the market competitiveness of the product. Similarly, for the sake of safety, wind resistance and waterproofness, companies often choose to use higher-strength materials and more secure connection structures, which will also increase production costs and reduce certain installation conveniences, thereby reducing the market competitiveness of the product. Moreover, after the existing bracket is installed, the orientation and angle of the photovoltaic panel are fixed, which will undoubtedly waste part of the daytime illumination time. In some places, there are many obstructions, and such a fixed structure greatly limits the installation range of the photovoltaic panel, increases the difficulty of using the bracket and reduces the power generation efficiency, which also reduces the market competitiveness of the product. Most existing brackets are transported in pieces and then installed in place. The installation of pieces not only increases the risk of installation errors but also greatly increases the installation time. In some special locations, there is no ability for personnel to stay for a long time, which undoubtedly greatly increases the safety risk and installation cost, so it will also reduce the market competitiveness of the product. Therefore, the present invention optimizes and improves the existing bracket structure to address the above problems. Summary of the Invention

A fifth folding rod 47 is rotatably provided on the fourth connecting seat 49, and a sixth folding rod 48 is rotatably provided on the fifth connecting seat. The ends of the fifth folding rod 47 and the sixth folding rod 48 that are away from each other are hinged to the fourth connecting seat 49 and the fifth connecting seat respectively, and the ends of the fifth folding rod 47 and the sixth folding rod 48 that are close to each other are hinged through the sixth connecting seat 50.

[0031] When the linkage mechanism is in operation, the first folding rod 43 and the second folding rod 44 are in a straight line, the third folding rod 45 and the fourth folding rod 46 on the same side are in a straight line, and the fifth folding rod 47 and the sixth folding rod 48 are in a straight line.

[0032] When the linkage mechanism is folded, the angle between the two diagonal braces 41 on the same side is minimized, as is the angle between the third and fourth folding rods 45, 46. The third and fourth folding rods 45, 46 are retracted upwards between the two diagonal braces 41 on the same side, making contact with the two diagonal braces 41 on the same side. The angle between the first and second folding rods 43, 44 is minimized, as is the angle between the fifth and sixth folding rods 47, 48. The spacing between the left and right diagonal braces 41 is minimized.

[0033] The present invention also provides a method for using a foldable solar photovoltaic panel quick installation bracket, comprising the following steps: Step 1: Before using this bracket, disengage the flip box 21 from the socket 20, and the photovoltaic panel 40 from the mounting mechanism. Position the flip lever 23 within the flip box 21, with the locking plate 30 securing it. The folding assembly between the two flip boxes 21 is folded, the linkage is folded, and the distance between the two flip boxes 21 is minimized. Gather all components and bring them to the designated location, ready for installation.

[0034] Step 2, when starting the installation, the leveling mechanism and the turntable frame 1 are in the same horizontal plane, hold the support column 4 and turn the leveling mechanism downward to keep the leveling mechanism vertical. Then lock the locking mechanism between the first articulated frame 2 and the first articulated seat 3, and then rotate each sliding sleeve 8 so that the lower end surface of each mounting plate 11 can be adjusted to fit the mounting surface. Then drive the expansion bolt 34 into the fixing hole of the mounting plate 11 to fix the mounting plate 11 on the roof of the RV. Then rotate the threaded sleeve 10 to adjust the height of the second articulated seat 9 to prevent the first electric push rod 5 from supporting the bottom of the turntable frame 1 when it is at the minimum length. Then start all the first electric push rods 5, and adjust the extension range of the piston rod of each first electric push rod 5 according to the data of the first level sensor 13 and the second level sensor 14, so that the turntable remains horizontal.

[0035] In step three, the staff member holds the two flip boxes 21 with both hands and pulls them outward with force, moving them away from each other. During this pulling process, the spacing between the pad rods 36 gradually increases, and the angle between the slide rod 39 and the pad rod 36 gradually increases. Simultaneously, the linkage mechanism gradually unfolds, gradually adjusting the first folding rod 43 and the second folding rod 44 to be aligned, the fifth folding rod 47 and the sixth folding rod 48 to be aligned, and the third folding rod 45 and the fourth folding rod 46 on the same side to be aligned. When the linkage mechanism is fully unfolded, the four flip boxes 21 are adjusted to their working angles, and the unfolded linkage mechanism supports the four flip boxes 21.

[0036] Step 4: Insert the elastic pins 32 on the four flip boxes 21 into the four sockets 20, securing the two mounting mechanisms to the turntable. Next, place the photovoltaic panel 40 on the flip rods 23 and pads 36 of the two mounting mechanisms, so that the lower end of the panel 40 is supported by a row of support blocks 38. Then, rotate the four pressure plates 35 over the edges of the panel 40 and tighten the bolts 34, securing the panel 40 firmly.

[0037] Step 5: When the weather is clear, the piston rod of the second electric push rod 27 extends, causing the sliding shaft 26 to slide upward inside the flip box 21, thereby driving the support rod 25 to lift the flip rod 23. The flip rod 23 rotates upward around the flip axis 22, and finally the two photovoltaic panels 40 are horizontally deployed to ensure maximum light-receiving area. At the same time, the first motor 15 drives the worm 16 to rotate, which drives the worm gear 17, which drives the driving gear 18, which drives the driven ring gear 19, which drives the turntable, which drives the mounting mechanism and the two photovoltaic panels 40 to rotate horizontally, thereby ensuring maximum light exposure time and greatly improving power generation capacity. When the weather is windy and rainy, the piston rod of the second electric push rod 27 retracts, causing the sliding shaft 26 to slide downward inside the flip box 21, thereby driving the support rod 25 to pull the flip rod 23 downward, and the flip rod 23 rotates downward around the flip axis 22 until it abuts the flip box 21. The second motor 31 then rotates the locking plate 30 via the rotating shaft 29, locking the tilting lever 23 and lowering the photovoltaic panel 40. The deployed linkage supports the mounting mechanism and the photovoltaic panel 40, ensuring maximum wind resistance. The tilted photovoltaic panel 40 also facilitates rainwater drainage, improving waterproofing.
