[0002] Photovoltaic (PV) brackets are structural systems used to fix and support photovoltaic (PV) modules. They must possess characteristics such as wind pressure resistance, snow load resistance, corrosion resistance, and long lifespan to ensure the stability and power generation efficiency of PV power plants. PV brackets are classified by material into steel brackets, aluminum alloy brackets, and flexible brackets. In the processing and production of steel brackets, steel strips are required. Currently, after steel strip processing, it is usually rolled into steel reels for subsequent PV bracket production. This process requires a steel strip storage device. However, existing steel strip storage devices only have a feeding function. After one reel is fed, a crane is needed to lift another reel and place it on the device for feeding. This operation requires a crane to be on standby near the device at all times, resulting in high crane occupancy. Furthermore, the method of repeatedly lifting and moving the steel reel to the device with a crane is complex and cumbersome, potentially impacting the production efficiency of PV brackets.

[0022] Example 1

[0023] A steel strip storage system for photovoltaic bracket production includes a base plate 1, the length of which can be set according to actual conditions. A pair of raised tracks 2 are arranged along the length of the base plate 1. A transfer trolley 3 is arranged between the two raised tracks 2, and track wheels 4 are mounted on the transfer trolley 3. The track wheels 4 are positioned on and matched with the raised tracks 2. A drive motor 5 is located at the lower base plate 31 of the transfer trolley 3. One end of the output shaft of the drive motor 5 is connected to a worm gear reducer 6. One end of the worm 60 extending outward from the worm gear reducer 6 is connected to the corresponding track wheel 4. In use, starting the drive motor drives the worm gear in the worm gear reducer 6 to rotate, which in turn drives the corresponding track wheel 4 to rotate, thus enabling the transfer trolley 3 to move along the raised tracks 2. The connection method between the drive motor 5 and the worm gear reducer 6, as well as the structure and working principle of the worm gear reducer 6, can be found in the prior art. A hydraulic cylinder 7 is installed inside the transfer trolley 3. A lifting platform 8 is fixed to the upper end of the hydraulic cylinder 7, and a placement groove 80 is provided on the upper side of the lifting platform 8. By controlling the extension of the hydraulic cylinder 7, the lifting platform 8 can be moved upward, thereby lifting the steel plate 13 above for transfer. The placement groove 80 improves the stability of the transfer of the steel plate 13. At the same time, the moving speed of the transfer trolley 3 is very slow, and the width of the steel plate 13 also has a certain stability. Therefore, during the transfer of the steel plate 13 by the transfer trolley 3, the steel plate 13 will not fall or shake.

[0024] A hydraulic tensioning uncoiler 9 is installed at one end of the base plate 1. The expansion and contraction drum 90 on the hydraulic tensioning uncoiler 9 corresponds to the transfer trolley 3. The structure and working principle of the hydraulic tensioning uncoiler 9 and the expansion and contraction drum 90 are the same as those of the hydraulic tensioning uncoilers currently sold on the market. When the transfer trolley 3 moves the steel disc 13 to the expansion and contraction drum 90, the expansion and contraction drum 90 is in a tightened state. When the steel disc 13 is placed on the expansion and contraction drum 90, the expansion and contraction drum 90 expands to limit and fix the steel disc 13 on it. When the material is unloaded, the steel disc 13 rotates with the expansion and contraction drum 90, thereby realizing the unloading. In actual operation, the transfer trolley 3 can move to the front of the hydraulic tensioning uncoiler 9 and place the steel disc 13 at the rear end of the expansion and contraction drum 90. A support frame 10 is fixed to the other end of the base plate 1. A storage shaft 11 corresponding to the transfer trolley 3 is fixed to the upper part of the support frame 10. Placement racks 12 are installed on both sides of the base plate 1. After installation, the lifting platform 8 is located between the two placement racks 12. In use, a crane is needed to lift the steel plate 13 onto the placement rack 12, and the storage shaft 11 passes through the central hole of the steel plate 13 to improve the storage stability of the steel plate 13. The control lines and oil pipes of the drive motor 5, worm gear reducer 6, and hydraulic cylinder 7 can be placed between the raised rails 2 according to the actual situation. The control lines and oil pipes are not shown in the figure. In actual operation, the movement of the transfer trolley can be controlled by a remote control.

A partition 32 is fixed between the side plates 30. The rear side plate is not shown in the figure. The hydraulic cylinder 7 and the lifting platform 8 are located in the space formed by the partition 32, the side plates 30, the rear side plate, and the lower base plate 31. Track wheels 4 are mounted on the side plates 30. The partition 32 is provided with through holes 70 for the hydraulic cylinder 7's oil pipe.

[0027] Based on Embodiment 1, a steel strip storage system for photovoltaic bracket production, in order to avoid the steel strip becoming loose and protruding during the feeding process of the steel tray 13, preferably, also has an mounting plate 14 and a cylinder 15 fixed on one side of the hydraulic tensioning uncoiler 9. The mounting plate 14 has a rotating mounting shaft 16, and a connecting plate 17 is fixed on the mounting shaft 16. One end of the connecting plate 17 is rotatably connected to the cylinder 15. An arc-shaped clamping rod 18 is fixed at the end of the mounting shaft 16 near the tensioning drum 90. A clamping roller 19 is rotatably mounted on the upper end of the arc-shaped clamping rod through the connecting shaft. The clamping roller 19 abuts against the circumferential surface of the steel tray 13 on the tensioning drum 90. In use, the extension of the cylinder 15 can be controlled to drive the installation shaft 16 to rotate through the connecting plate 17, which in turn drives the arc-shaped clamping rod 18 to move, so that the clamping roller 19 abuts against the circumferential surface of the steel disc 13 on the expansion and contraction drum 90, thereby realizing the clamping operation of the steel strip. In actual operation, the extension speed of the cylinder 15 can be adjusted to ensure that the clamping roller 19 always abuts against the circumferential surface of the steel disc 13 on the expansion and contraction drum 90.

In use, multiple steel discs 13 can be lifted onto the placement racks 12 at one time with the help of a crane. Then, the storage shaft 11 passes through the central hole of the steel disc 13 to improve the placement stability of the steel disc 13. Then, the drive motor 5 is started and the worm gear reducer 6 drives the transfer trolley 3 to move along the raised track 2 to the bottom of the steel disc 13. When the hydraulic cylinder 7 is extended, the lifting platform 8 is lifted up to lift the steel disc 13 so that the bottom of the steel disc 13 leaves the placement rack 12.
