[0002] With the large-scale popularization of clean energy, the installed capacity of photovoltaic power generation has been increasing year by year. Currently, photovoltaic power generation is generally installed in areas such as flat ground, mountains, and water. In some areas, it is difficult for vehicles to directly reach. Therefore, hoisting devices such as cranes are needed to hoist and install components such as photovoltaic panels. When the existing photovoltaic panels are hoisted, they are usually hoisted one by one, and after all the photovoltaic panels are hoisted in place, they are assembled together. This leads to a slow speed and low efficiency in the entire installation and construction process, a relatively long installation process, and high construction cycle and cost. Content of the Utility Model

A plurality of hoisting holes are arranged at the edge of the hoisting bracket. A plurality of sliding columns are slidably connected to the hoisting bracket in the vertical direction. A compression spring is arranged between the sliding column and the hoisting bracket. A locking hook is rotatably connected to the sliding column. A plurality of through holes are arranged on the purlins. Slots are arranged at positions on the hoisting bracket corresponding to the through holes. One end of the locking hook passes through the through hole and is movably inserted into the slot.
[0006] Further, a plurality of through sliding holes are arranged on the hoisting bracket. The sliding columns are slidably connected in the sliding holes.

[0010] Further, a plurality of reinforcing rings are arranged at the end of the hoisting bracket.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. The structure of the present utility model fixes multiple purlins through a lifting bracket, and the purlins are used to fix multiple photovoltaic panels and floating barrels. Such a structure enables the lifting bracket to effectively carry and fix multiple assembled photovoltaic panels through fixation with multiple purlins. During lifting, a crane and ropes are connected to multiple lifting holes at the edge of the lifting bracket, and the rapid lifting operation of multiple assembled photovoltaic panels can be achieved simultaneously.

[0022] Refer to Figure 2 and Figure 3, the utility model relates to a hoisting device for photovoltaic modules. The main structure includes a hoisting bracket 2 connected to a plurality of purlins 1. The cross-section of the hoisting bracket 2 is rectangular, and its opposite sides are both connected to the purlins 1. The purlins 1 are made of metal. A plurality of floating barrels 3 and photovoltaic panels 4 are arranged on the purlins 1. The purlins 1 are used to connect and fix the plurality of photovoltaic panels 4 and floating barrels 3, so that the plurality of photovoltaic panels 4 form a linear array structure. The hoisting bracket 2 is fixed to the plurality of purlins 1, so that the plurality of photovoltaic panels 4 are assembled into a rectangular array structure, which is convenient for hoisting the assembled photovoltaic panels 4. A plurality of through hoisting holes 5 are provided at the edge of the hoisting bracket 2. When hoisting it, the ropes of the crane pass through the hoisting holes 5 and are fixed to the hoisting bracket 2. Preferably, the hoisting holes 5 are symmetrically arranged on both sides of the hoisting bracket 2. A plurality of sliding columns 6 are slidably connected to the hoisting bracket 2 in the vertical direction. The sliding columns 6 can slide upward under the action of an external force. A compression spring 7 is provided between the sliding columns 6 and the hoisting bracket 2. The compression spring 7 is in a compressed state. When the sliding columns 6 slide upward, the compression spring 7 is further compressed. A locking hook 8 is rotatably connected to the sliding columns 6 through bearings. The longitudinal section of the locking hook 8 is in the shape of a hook. Such a structure makes the locking hook 8 tend to move downward under the elastic force of the compression spring 7. A plurality of through holes 9 are provided on the purlins 1. Slots 10 are provided at positions on the hoisting bracket 2 opposite to the through holes 9. One end of the locking hook 8 passes through the through hole 9 and is movably inserted into the slot 10. When it is necessary to fix the hoisting bracket 2 and the purlins 1, align the through hole 9 on the purlins 1 with the slot 10 on the hoisting bracket 2, pull the locking hook 8 upward to drive the sliding columns 6 to slide upward and compress the compression spring 7, then rotate the locking hook 8 so that one end of it is aligned with the through hole 9. After that, release the locking hook 8, and under the action of the compression spring 7, the sliding columns 6 and the locking hook 8 will slide downward and reset, so that one end of the locking hook 8 passes through the through hole 9 downward and is inserted into the slot 10. Under the action of the compression spring 7, the locking hook 8 is kept inserted and fixed in the slot 10, so that the purlins 1 are restricted on the hoisting bracket 2 by the cooperation of the locking hook 8 and the slot 10. The hoisting bracket 2 is located below the purlins 1. During the subsequent hoisting of the hoisting bracket 2, it can carry a plurality of purlins 1 and photovoltaic panels 4, making the relative structure of the purlins 1 and the hoisting bracket 2 more stable, not prone to misalignment and slipping during hoisting, ensuring the stability of the hoisting of the photovoltaic panels 4, and making the connection and disassembly of the hoisting bracket 2 and the purlins 1 more convenient, further simplifying the hoisting steps, improving the hoisting construction efficiency, and greatly reducing the installation construction period and cost of the photovoltaic panels 4.
[0023] Preferably, referring to Figure 5, a plurality of through sliding holes 11 are provided on the hoisting bracket 2, the sliding column 6 is slidably connected in the sliding holes 11, and the arrangement of the sliding holes 11 provides guidance for the sliding of the sliding column 6, so that the sliding column 6 and the locking hook 8 can be hidden in the sliding holes 11 when sliding downward, and can slide upward and extend out of the outside of the sliding holes 11 during use. A convex block 12 is fixedly welded or integrally formed at the bottom of the sliding column 6, and the cross-sectional area of the convex block 12 is larger than the cross-sectional area of the sliding hole 11. Such a structure enables the convex block 12 to limit the maximum sliding distance of the sliding column 6 when pulling the sliding column 6 upward, so that the sliding column 6 and the locking hook 8 will not be separated from the hoisting bracket 2, ensuring the firmness of the locking hook 8 assembly.
[0024] Preferably, the compression spring 7 is sleeved outside the sliding column 6, and the compression spring 7 is arranged between the hoisting bracket 2 and the convex block 12. Such a structure makes the structure of the compression spring 7 more firm, and can accurately compress the compression spring 7 when the sliding column 6 slides, so that the reverse elastic force generated acts accurately on the sliding column 6 and the locking hook 8, thereby ensuring the stability of the fixing structure of the locking hook 8 to the purlin 1.
[0025] Preferably, a magnetic block 13 is welded or bolt-fixed in the slot 10, and the magnetic block 13 is magnetically attracted to the end of the locking hook 8. The arrangement of the magnetic block 13 can magnetically attract the end of the locking hook 8, making the plug-in structure of the locking hook 8 and the slot 10 more firm. Further, the magnetic block 13 is made of an electromagnet material, and a power supply for supplying power to multiple electromagnets simultaneously and a switch for controlling the on-off of the current of the electromagnet are arranged on the hoisting bracket 2. When hoisting, the switch is closed to make the magnetic block 13 generate magnetism and attract and fix the locking hook 8. After hoisting is completed, the switch is disconnected, so that the locking hook 8 can be more easily pulled upward to be separated from the magnetic block 13, releasing the fixation of the purlin 1, and further making the connection and fixation structure of the purlin 1 more stable, and further simplifying the connection and disassembly steps of the hoisting bracket 2.
[0026] Preferably, referring to Figure 4 , a plurality of legs 14 are welded or bolt-fixed to the bottom of the hoisting bracket 2. The arrangement of the legs 14 makes the bottom of the hoisting bracket 2 suspended, thereby leaving space for the arrangement of the bottom sliding column 6 and the compression spring 7, ensuring the smoothness of the up and down sliding of the sliding column 6, and improving the stability of the cooperation between the locking hook 8 on the hoisting bracket 2 and the purlin 1.
[0027] Preferably, referring to Figure 1 , a plurality of reinforcing rings 15 are provided at the end of the hoisting bracket 2. Since the rope passes through the hoisting hole 5 at the edge of the hoisting bracket 2 during hoisting, the reinforcing rings 15 made of metal material are sleeved at the end position of the hoisting bracket 2, so that the structural strength of the hoisting position of the hoisting bracket 2 is further improved, ensuring the stability of the hoisting structure, and improving the overall service life of the hoisting bracket 2.
[0028] Working principle: The structure of the utility model fixes multiple purlins 1 through the lifting bracket 2, and the purlins 1 are used to fix multiple photovoltaic panels 4 and floating barrels 3. Such a structure enables the lifting bracket 2 to effectively carry and fix multiple assembled photovoltaic panels 4 through fixation with multiple purlins 1. During lifting, the crane and ropes are connected to multiple lifting holes 5 on the edge of the lifting bracket 2, and the rapid lifting operation of multiple assembled photovoltaic panels 4 can be achieved simultaneously. After lifting in place, the multiple assembled photovoltaic panels 4 are simply spliced again, making the entire installation and construction process faster and more efficient, reducing the number of liftings, improving the lifting efficiency, and greatly shortening the lifting construction period and cost; A plurality of sliding columns 6 are slidably connected to the lifting bracket 2 along the vertical direction. A compression spring 7 is provided between the sliding columns 6 and the lifting bracket 2. A locking hook 8 is rotatably connected to the sliding columns 6. A plurality of through holes 9 are provided on the purlin 1, and a slot 10 corresponding to the position of the through holes 9 is provided on the lifting bracket 2. After the locking hook 8 rotates, one end of it passes through the through hole 9 and is movably inserted into the slot 10. Such a structure makes it possible to fix the lifting bracket 2 and the purlin 1. Only need to pull up the locking hook 8, drive the sliding column 6 to slide upward to compress the compression spring 7, then rotate the locking hook 8 so that one end of it rotates above the through hole 9 on the purlin 1, and then release the locking hook 8. Under the elastic force of the compression spring 7, the locking hook 8 and the sliding column 6 slide downward to reset, so that one end of the locking hook 8 passes through the through hole 9 and is inserted into the slot 10 to achieve the rapid fixation of the purlin 1 and the lifting bracket 2. Reverse operation can be carried out during disassembly. When the lifting bracket 2 is lifted, it can effectively carry the assembled purlin 1 and multiple photovoltaic panels 4 from the bottom, avoid the misalignment and shaking of the photovoltaic panels 4 relative to the lifting bracket 2, ensure the firmness of the photovoltaic panels 4 during the lifting process, and the disassembly and connection of the lifting bracket 2 and the purlin 1 are faster and more convenient, further simplifying the lifting process and improving the lifting construction efficiency.
