[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1 As shown, the offshore photovoltaic power station construction hoisting equipment of this utility model embodiment includes a base 1, a floating box 2, a frame 3, a first cross brace 4, a second cross brace 5, and an electric hoist 6.

[0023] The pontoon 2 is located at the bottom of the base 1 along the height direction z. In this way, the pontoon 2 can provide buoyancy to the base 1, which is beneficial to offshore photovoltaic construction.

[0024] Two frames 3 are arranged along the length direction x. Frame 3 includes a first column 31, a second column 32, a first crossbeam 33, and a second crossbeam 34. The first column 31 and the second column 32 are arranged along the width direction y, and along the height direction z. The bottoms of the first column 31 and the second column 32 are fixed to the top of the base 1. The two ends of the first crossbeam 33 are fixed to the tops of the first column 31 and the second column 32. The two ends of the second crossbeam 34 are fixed to the middle of the first column 31 and the second column 32. The two ends of the first cross brace 4 are fixed to the middle of the first column 31 of the two frames 3. The two ends of the second cross brace 5 are fixed to the middle of the second column 32 of the two frames 3.

[0025] The electric hoist 6 is slidably connected to the first crossbeam 33 of the frame 3. Specifically, the first crossbeam 33 has an automatic slide rail, on which the electric hoist 6 slides, which is beneficial for hoisting operations.

[0026] During operation, the offshore photovoltaic power station construction hoisting equipment of this embodiment is moved between multiple steel pipe piles pre-fixed on the seabed. A transport vessel is used to transport the photovoltaic support structure to be hoisted to the outside of the offshore photovoltaic power station construction hoisting equipment of this embodiment. After the photovoltaic support structure is transported to its position, the position of the electric hoist 6 is adjusted to lift the photovoltaic support structure from the transport vessel. The photovoltaic support structure is then hoisted sequentially onto the upper part of the steel pipe piles, ensuring that the installation requirements are met, and welded and fixed according to the design requirements. After welding and fixing are completed, the transport vessel and the offshore photovoltaic power station construction hoisting equipment of this embodiment are moved to the next installation area, and the above operation is repeated to carry out the photovoltaic support structure hoisting operation.

[0027] Based on the above structural setup, the overall structure is stable and reliable by combining and installing the frame 3, the first cross brace 4, and the second cross brace 5, and the electric hoist 6 facilitates the construction and hoisting of the offshore photovoltaic power station.

[0028] like Figure 2 As shown, in some embodiments, the pontoons 2 are provided in two sets and arranged along the width direction y. This makes the buoyancy force on the base 1 more even.

[0029] like Figure 2 As shown, in some embodiments, a drive unit 7 is also included, which is mounted at one end of the base 1 along the length direction x and located between the two sets of floats 2. Specifically, the drive unit 7 employs an adjustable pitch propeller, enabling the base 1 to move autonomously.

[0030] like Figure 2As shown, in some embodiments, the frame 3 further includes a first scissor brace 35. The first column 31, the second column 32, the first crossbeam 33, and the second crossbeam 34 enclose a first installation space 3a, and the first scissor brace 35 is disposed in the first installation space 3a. Thus, the strength of the upper structure of the frame 3 can be improved by the first scissor brace 35.

[0031] like Figure 2 As shown, in some embodiments, the frame 3 further includes a second scissor brace 36. The first column 31, the second column 32, the second beam 34, and the base 1 enclose a second installation space 3b, and the second scissor brace 36 is disposed in the second installation space 3b. Thus, the second scissor brace 36 can improve the strength of the lower structure of the frame 3.

[0032] like Figure 1 and Figure 3 As shown, in some embodiments, a first diagonal brace 8 and a second diagonal brace 9 are also included. The top end of the first diagonal brace is fixed to the middle of the first horizontal brace 4, and the bottom end of the first diagonal brace 8 is fixed to the bottom of the first column 31. The top end of the second diagonal brace 9 is fixed to the middle of the second horizontal brace 5, and the bottom end of the second diagonal brace 9 is fixed to the bottom of the second column 32. In this way, the lower connection strength of the two frames 3 can be improved by the first diagonal brace 8 and the second diagonal brace 9.

[0033] like Figure 1 and Figure 3 As shown, in some embodiments, a third cross brace 10 and a fourth cross brace 11 are also included. The two ends of the third cross brace 10 are fixed to the top of the first column 31 of the two frames 3, and the two ends of the fourth cross brace 11 are fixed to the top of the second column 32 of the two frames 3. In this way, the third cross brace 10 and the fourth cross brace 11 can improve the upper connection strength of the two frames 3.

[0034] like Figure 1 As shown, in some embodiments, a fifth cross brace 12 is also included, with both ends of the fifth cross brace 12 fixed to the third cross brace 10 and the fourth cross brace 11. In this way, the upper connection strength of the two frames 3 can be further improved by the fifth cross brace 12.

[0035] like Figure 1 As shown, in some embodiments, the frame 3 further includes a herringbone beam 37, which is fixed to the top of the first crossbeam 33. Thus, the herringbone beam 37 can enhance the strength of the upper structure of the frame 3.

[0036] like Figure 1 As shown, in some embodiments, the frame 3 further includes a vertical brace 38, the upper end of which is fixed to the chevron beam 37, and the lower end of which is fixed to the first crossbeam 33. Thus, the vertical brace 38 can enhance the structural strength of the chevron beam 37.

[0037] It should be noted that the frame 3, first horizontal brace 4, second horizontal brace 5, first diagonal brace 8, second diagonal brace 9, third horizontal brace 10, fourth horizontal brace 11 and fifth horizontal brace 12 in the above embodiment can be made of steel pipe, angle steel and I-beam structure, and the connection is fixed by welding or by bolts.
