[0020] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0021] The embodiment of the present utility model discloses a hoisting device for the upper structure of an offshore photovoltaic.

[0022] The present utility model provides as Figure 1-2A hoisting sling device for the upper structure of an offshore photovoltaic power station, comprising a hoisting hook 1, a hoisting rope 2, a support truss beam 3, a universal rotating head 4, a sling 5 and a shackle 6. The hoisting rope 2 is arranged between the top corners of the support truss beam 3 and the hoisting hook 1. The universal rotating head 4 is rotatably arranged at the corner of the support truss beam 3. The universal rotating head 4 is rotatably connected to the support truss beam 3 by a universal joint. The sling 5 is arranged at the corner of the support truss beam 3 through the universal rotating head 4. The shackle 6 is arranged at the lower end of the sling 5. The support truss beam 3 is a square truss beam. The universal rotating head 4, the sling 5 and the shackle 6 are all arranged at the four corners of the support truss beam 3. The four corners of the upper structure of the photovoltaic power station are connected through the four shackles 6, and then the sling 5 can be hoisted and connected to the support truss beam 3. During this process, due to the different sizes of the photovoltaic modules, the sling 5 and the shackle 6 can be rotated at multiple angles through the universal rotating head 4, so as to ensure the stable hoisting of the upper structure of the photovoltaic power station. Finally, the hoisting operation is completed through the hoisting hook 1 and the hoisting rope 2. During the whole hoisting operation, only vertical loads are borne, and the support truss beam 1 only bears axial loads. The height of the whole set of slings is controlled at about 45 meters.

[0023] In order to increase the service strength of the hoisting rope 2 and the sling 5, as Figure 1-2 shown, both the hoisting rope 2 and the sling 5 are made of high-molecular ropes. The high-molecular material has high structural strength, strong corrosion resistance, and extended service life.

[0024] And in order to enable the hoisting rope 2 to hoist the support truss beam 3 stably, as Figure 1-2 shown, the included angle between the hoisting rope 2 and the support truss beam 3 is 49°. This angle can ensure that the hoisting rope 2 hoists the support truss beam 3 stably.

[0025] Finally, in order to connect the upper structure of the photovoltaic power station, as Figure 1-2 shown, the shackle 6 is a U-shaped part, and bolts and nuts that cooperate with each other are arranged at the opening of the U-shaped part. The upper structure of the photovoltaic power station can be fixed inside the shackle 6 by loosening the bolts and nuts.

[0026] Only some exemplary embodiments of the present invention are described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
