[0040] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0041] The lifting equipment support 100 for offshore photovoltaic construction according to the embodiment of the present invention includes a pipe column body 1, a first rib plate 21, a second rib plate 22 and a jacking assembly 3. The pipe column body 1 has a first section and a second section. The bottom of the pipe column body 1 abuts against the lower deck 41 of the hull, and the pipe column body 1 penetrates through the upper deck 42 of the hull. The first section is used to connect with the lower deck 41 of the hull, and the second section is used to connect with the upper deck 42 of the hull.

[0042] The number of the first rib plates 21 is multiple. The multiple first rib plates 21 are arranged circumferentially on the outer wall of the first section of the pipe column body 1. The first rib plates 21 are used to connect and fix the pipe column body 1 and the lower deck 41; the number of the second rib plates 22 is multiple. The multiple second rib plates 22 are arranged circumferentially on the outer wall of the second section of the pipe column body 1. The second rib plates 22 are used to connect and fix the pipe column body 1 and the lower deck 41; the jacking assembly 3 is arranged circumferentially on the first section and the second section of the pipe column body 1 and is used to jack and support the circumferences of the first section and the second section of the pipe column body 1.

[0043] The bottom of the pipe column body 1 abuts against and is fixed to the lower deck 41. In order to ensure the effective connection between the pipe column body 1 and the lower deck 41, a plurality of first rib plates 21 are welded between the lower deck 41 and the first section of the pipe column body 1. At the same time, a jacking assembly 3 is arranged circumferentially on the pipe column body 1 to realize the circumferential compression of the pipe column body 1. When a lateral force acts on the pipe column body 1, not only part of the first rib plates 21 bear the force, but also most of the force can be transmitted to the hull through the jacking assembly 3, thereby reducing the force borne by the first rib plates 21.

[0044] The first rib plate 21 has the function of fixing and limiting the bottom of the pipe column body 1. The pressing component 3 corresponding to the first section can disperse and transfer the lateral force borne by the bottom of the pipe column body 1 to the hull through a larger acting surface.

[0045] The effects achieved by the second rib plate 22 and the pressing component 3 located in the second section are roughly the same as those achieved by the first rib plate 21 and the pressing component 3 located in the first section, so they will not be elaborated here.

[0046] In the embodiment of the present invention, by fixing the pipe column body 1 through the upper deck 42 and the lower deck 41, the structural stability of the support is greatly improved, the lifting equipment can bear greater forces and operate more stably.

[0047] The support 100 for the lifting equipment used in the offshore photovoltaic construction in the embodiment of the present invention can strengthen the connection between the pipe column body 1 and the hull through the first rib plate 21 and the second rib plate 22, and can brace the circumferential direction of the pipe column body 1 through the pressing component 3 to increase the force-bearing area, thereby avoiding the problem of stress concentration in local areas of the pipe column body 1 or the hull and improving the structural stability of the support.

[0048] Optionally, both the first rib plate 21 and the second rib plate 22 can be steel plates in an approximate triangular shape.

[0049] In some embodiments, the pressing component 3 includes a fixed block 31, a movable block 32 and a fastening component. The number of fixed blocks 31 is multiple, and the fixed blocks 31 are arranged between two adjacent first rib plates 21 or two adjacent second rib plates 22. The fixed block 31 has a first abutting surface 311 and a second abutting surface 312, and the first abutting surface 311 abuts against the outer wall of the pipe column body 1; the number of movable blocks 32 is multiple, and the movable blocks 32 are arranged in one-to-one correspondence with the fixed blocks 31. The movable block 32 has a third abutting surface 321, and the third abutting surface 321 abuts against the second abutting surface 312; the fastening component is arranged between the hull and the movable block 32, and the fastening component is used to drive the movable block 32 to move towards the fixed block 31 so that the fixed block 31 braces the circumferential side wall of the pipe column body 1.

[0050] The dimension of the first abutting surface 311 of the fixed block 31 in the circumferential direction of the pipe column body 1 matches the distance between two adjacent first rib plates 21 or between two adjacent second rib plates 22, so that most areas in the circumferential direction of the pipe column body 1 can be pressed by the fixed block 31, greatly reducing the problem of local stress concentration.

[0051] The fastening component can be a screw rod or a power push rod such as a hydraulic cylinder.

[0052] In some embodiments, both the first abutting surface 311 and the third abutting surface 321 are inclined surfaces at a preset angle to the vertical direction.

[0053] After the fixed block 31 and the movable block 32 come into contact with each other, the second abutting surface 312 and the third abutting surface 321 come into contact. Since the second abutting surface 312 and the third abutting surface 321 are arranged as inclined surfaces, while the side surface of the pipe column body 1 is subjected to a horizontal jacking force, the fixed block 31 can also be subjected to a vertical downward component force, ensuring the stable position of the fixed block 31 and preventing the fixed block 31 from shifting.

[0054] Furthermore, the fastening member includes a support ring 33, a top plate 34, and a jacking member 35. The support ring 33 is fixedly connected to the hull. The support ring 33 is coaxially arranged with the pipe column body 1 and is located outside the pipe column body 1. The top plate 34 is fixed to the top of the support ring 33. The top plate 34 is provided with a threaded hole, and the jacking member 35 has a threaded section. The jacking member 35 is connected in the threaded hole.

[0055] The fixed block 31 further has a fourth abutting surface 322 and an upper end surface 323. The fourth abutting surface 322 abuts against the inner wall surface of the support ring 33, and the jacking member 35 abuts against the upper end surface 323.

[0056] The support ring 33 is welded to the hull. The support ring 33 is coaxially arranged with the pipe column body 1 and is located outside the pipe column body 1. After the movable block 32 and the fixed block 31 are arranged in position between the support ring 33 and the pipe column body 1, the top plate 34 is welded and fixed to the top of the support ring 33. Then the jacking member 35 is connected to the top plate 34. At this time, the lower end of the jacking member 35 can abut against the upper end surface 323 of the movable block 32. As the jacking member 35 moves downward, the third abutting surface 321 of the movable block 32 will fit with the second abutting surface 312 of the fixed block 31, and the fourth abutting surface 322 of the movable block 32 will abut against the inner wall surface of the support ring 33. By controlling the downward displacement of the jacking member 35, the magnitude of the jacking force on the pipe column body 1 can be adjusted.

[0057] In some embodiments, the fastening member further includes a third rib plate 36. The third rib plate 36 is arranged on the circumferential outer side of the support ring 33. The third rib plate 36 is used to connect the support ring 33 and the hull.

[0058] The third rib plate 36 is used to brace the structure of the support ring 33 so that the support ring 33 does not deform, and the force acting on the support ring 33 is dispersed to the hull through the third rib plate 36, improving the structural stability of the support.

[0059] In some embodiments, there are three sets of jacking assemblies 3. One set of the jacking assemblies 3 is arranged between the pipe column body 1 and the lower deck 41, and the other two sets of jacking assemblies 3 are respectively arranged on the upper and lower sides of the upper deck 42.

[0060] It should be understood that since the lower end of the pipe column body 1 abuts against the lower deck 41, only the housing of the top pressing assembly 3 needs to be arranged on the upper side of the lower deck 41, while the pipe column body 1 penetrates through the upper deck 42. To improve the structural stability, the top pressing assembly 3 is arranged on both the upper and lower sides of the upper deck 42, which can further optimize the force between the upper deck 42 and the pipe column body 1.

[0061] In some embodiments, the pipe column body 1 further includes a plurality of reinforcing plates 11. The plurality of reinforcing plates 11 are arranged on the inner wall of the pipe column body 1 along the circumferential direction of the pipe column body 1. The reinforcing plates 11 extend in the vertical direction, and the lower ends of the reinforcing plates 11 extend to the bottom of the pipe column body 1, and the upper ends of the reinforcing plates 11 extend above the upper deck 42.

[0062] To prevent the pipe column body 1 from deforming, a reinforcing plate 11 is provided inside the pipe column body 1 to increase the lateral force received by the pipe column body 1 and prevent the pipe column body 1 from bending and deforming axially.

[0063] Due to the effect of the force arm, the lower part of the support receives a greater lateral force. Therefore, the lower part of the reinforcing plate 11 extends to the lower deck 41, and the upper part of the reinforcing plate 11 extends at least to the upper part of the upper layer.

[0064] In some embodiments, the pipe column body 1 further includes a connecting rod 12. At least some of the reinforcing plates 11 are grouped in pairs to form a reinforcing plate group. The connecting rod 12 is connected between two reinforcing plates 11 in the same reinforcing plate group, and a plurality of connecting rods 12 are arranged between the two reinforcing plates 11 in each reinforcing plate group.

[0065] It should be understood that two reinforcing plates 11 arranged opposite to each other along the radial direction of the pipe column body 1 are used as a reinforcing plate group. The two reinforcing plates 11 are braced by the connecting rod 12, so that the pipe column body 1 not only bears the top pressing force from the outside to the inside, but also has a certain bracing force inside the pipe column body 1, improving the structural stiffness of the pipe column body 1 and making its stability better.

[0066] Optionally, the connecting rod 12 is a telescopic rod. During installation, the length of the telescopic rod can be adjusted to control the bracing force acting between the two relatively arranged reinforcing plates 11.

[0067] The sea crane equipment of the embodiment of the present invention includes a lifting device 5 and a lifting equipment support 100 for offshore photovoltaic construction as described in any one of the above. The lifting device 5 is arranged on the top of the lifting equipment support 100 for offshore photovoltaic construction.

[0068] In some embodiments, the lifting device 5 also includes a frame 51 and a hoist 52. The number of the frame 51 and the lifting equipment support 100 for offshore photovoltaic construction are both two. The frame 51 is arranged on the lifting equipment support 100 for offshore photovoltaic construction, and the hoist 52 is supported on the top of the two frames 51, which can ensure the structural stability of the offshore lifting equipment, so that the hoist 52 is more stable when lifting materials, and the offshore lifting equipment is stably stressed, thereby reducing the risk of construction operations and increasing the service life of the offshore lifting equipment.
