Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a technical solution: a floating transportation device for offshore wind power steel pipe piles, comprising a floating body 1 connected to a tugboat through a connecting rope, a fixing assembly for fixing the outer wall of the steel pipe pile is provided on the floating body 1, and a plurality of fixing assemblies are provided to fix the multi-point positions in the length direction of the steel pipe pile. The floating body 1 in this solution can be used to place a plurality of steel pipe piles, and a plurality of rows of fixing assemblies are provided correspondingly according to the number of steel pipe piles, and each row of fixing assemblies is respectively used to fix the multi-point positions of the steel pipe piles, and the number of steel pipe piles in each row is set according to the fixing effect, and three groups are used for each row in this solution;

[0025] The fixing assembly includes an L-shaped plate 2 and a support plate 3. The L-shaped plates 2 are symmetrically arranged on both sides of the support plate 3 and are both rotatably arranged on the floating body 1. The support plate 3 is slidably arranged on the floating body 1 up and down and drives the L-shaped plate 2 to rotate by pressing down one end of the L-shaped plate 2.

[0026] Specifically, the L-shaped plate 2 includes a vertical plate 22 and a horizontal plate 21. A hinge seat 4 is provided on the floating body 1. The bottom end of the vertical plate 22 is inserted into the hinge seat 4 and is rotated on the hinge seat 4 through a short axis. The horizontal plate 21 is located below the support plate 3. In the initial state, the support plate 3 is at the highest point. The gravity on one side of the vertical plate 22 is greater than that on the other side of the horizontal plate 21. Under the limiting action of the support plate 3, the L-shaped plate 2 tilts outward, which is convenient for the placement of the steel pipe piles, and will not cause the horizontal plate 21 to separate from the support plate 3. It should be noted that in order to make the L-shaped plate 2 better maintain the state of tilting outward when the steel pipe piles are not placed on the support plate 3, a counterweight block 5 can be set on the outside of the L-shaped plate 2.

[0027] Specifically, a pressing plate 6 is provided on one side of the vertical plate 22 for pressing the steel pipe pile. The pressing plate 6 is slidably set on the vertical plate 22. An adjusting bolt 7 is threadedly connected to the vertical plate 22. One end of the adjusting bolt 7 is inserted into the pressing plate 6 and forms a rotational connection with the pressing plate 6. After the steel pipe pile is placed on the supporting plate 3, the pressing effect of the pressing plate 6 on the steel pipe pile can be adjusted by rotating the adjusting bolt 7.

[0028] Specifically, sliding rods 8 are provided on the upper and lower sides of the pressure plate 6, and sliding holes 9 for the sliding rods 8 to slide are provided on the vertical plate 22. A plastic layer is provided on one side of the pressure plate 6 for fixing the steel pipe piles, and an arc surface is provided on the plastic layer. When the pressure plate 6 is moved, the pressure plate 6 will not rotate through the cooperation of the sliding rods 8 and the sliding holes 9, so that the pressure plate 6 with the arc surface is better located in the clamping position. Among them, the plastic layer can be made of rubber material, which has plastic deformation ability and can also produce a greater friction fixing effect on the steel pipe piles.

[0029] Specifically, a roller 10 is rotatably provided at one end of the horizontal plate 21 away from the vertical plate 22 , and when the support plate 3 moves up and down and abuts against the horizontal bar, the friction force with the horizontal plate 21 can be greatly reduced, so that the horizontal plate 21 can move smoothly.

[0030] Specifically, a socket 12 is provided on the top of the floating body 1, a limiting groove is provided at the bottom of the socket 12, a spring 14 is provided at the bottom of the limiting groove, a rod 11 is provided at the bottom of the support plate 3 for inserting into the socket 12, a limiting plate 13 is provided at the bottom of the rod 11 for forming a sliding connection with the limiting groove, and the bottom end of the limiting plate 13 is against the spring 14. The spring 14 can make the support plate 3 be located at the highest point when it is not subjected to the pressure of the steel pipe pile. At this time, the L-shaped plate 2 can also be in a state of tilting outward, which is convenient for the placement of the steel pipe pile.

[0031] Specifically, a support seat 15 is provided at the top of the floating body 1 below each group of support plates 3. After the steel pipe piles are placed on the support plates 3 and the support plates 3 are attached to the support seats 15, the pressure plates 6 are in a state of pressing the outer walls of the steel pipe piles, and the support seats 15 can support the support plates 3. It should be supplemented that an arc-shaped groove can be provided on the top of the support plate 3, and the arc-shaped groove is provided in the middle of the support plate 3, so that the steel pipe piles can be fixed more stably after being placed therein.

[0032] A specific application example of this embodiment is:

[0033] When the device is in use, the steel pipe pile is hoisted on the floating body 1 by the hoisting device, and the steel pipe pile is slowly dropped and placed between the L-shaped plates 2 on both sides of the multiple sets of fixing components; the descent of the steel pipe pile will drive the support plate 3 to move downward, and the support plate 3 will contact the roller 10 and press the cross plate 21 downward, thereby driving the L-shaped plates 2 on both sides of the steel pipe pile to rotate toward the side close to each other, driving the pressing plate 6 to press the upper part of the steel pipe pile until the support plate 3 moves down to abut against the support seat 15. This method can compress and fix the steel pipe pile itself by the gravity, has a good fixing effect, and is convenient to fix. After fixing, the floating body 1 can be transported to the offshore wind power installation location by a tugboat; after the steel pipe pile is lifted by the hoisting device, the support plate 3 will automatically rise under the action of the spring 14, and the L-shaped plate 2 will be in an outwardly inclined state again under the action of the counterweight block 5, which is convenient for the next placement of the steel pipe pile.
