A floating pontoon support structure for assisting in the construction of a double-head fan cable

Abstract

This application discloses a pontoon support structure for assisting in the construction of cables for floating dual-head wind turbines, comprising: a pontoon support structure that provides temporary constraint to the lower end of the cable at the connection point on the pontoon. The pontoon support structure of this application enables the lower end of the cable to be temporarily constrained at the connection point on the pontoon, solving the problem that the pontoon itself does not provide temporary constraint to the lower end of the cable during pre-laying and adjustment.

Description

Technical Field

[0001] This utility model relates to a floating support structure for assisting in the construction of floating double-headed wind turbine cables, belonging to the field of wind turbine cable construction technology. Background Technology

[0002] During the construction of floating wind turbines, stability or tension adjustment is achieved through the tensile force of the cable installation. The relevant technology can be found in Chinese Patent Publication No. CN220764655U.

[0003] When the lower end of the cable is connected to the buoy, in order to ensure that the position does not change after the connection, the cable needs to be laid and adjusted in advance. However, the buoy itself does not have the function of temporarily restraining the lower end of the cable. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a floating support structure for assisting in the construction of floating double-headed wind turbine cables.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a floating support structure for assisting in the construction of floating double-headed wind turbine cables, comprising:

[0007] This allows the lower end of the cable to be temporarily constrained at the point where the pontoon is to be connected, forming a pontoon support structure.

[0008] The float support structure includes an upper frame, a lower structure, a lifting beam, a flange for fixed connection with the float, lifting points, and a winch wire rope.

[0009] A lower structure is fixed to the flange, and a lifting beam is fixedly connected to the top of the lower structure. Both ends of the lifting beam extend to the outside of the top of the lower structure.

[0010] The lifting beam has lifting points at both ends, and a winch wire rope is connected to the lifting points to temporarily restrain the lower end of the cable.

[0011] An upper structural frame is fixed to the middle of the lifting beam, and the upper structural frame has reinforcing arms that strengthen the connection between the two ends of the extended lifting beam.

[0012] Working principle: When in use, the entire structure of the pontoon support is lifted to the top of the pontoon using a crane. The flange and the pontoon are fixedly connected with bolts and nuts. During installation, the lifting beam and lifting points are aligned with the direction of the cables on both sides.

[0013] The beneficial effects of this utility model are as follows: the float support structure of this application enables the lower end of the cable to be temporarily constrained at the point where the float is to be connected, thus solving the problem that the float itself does not have the function of temporarily constraining the lower end of the cable when the cable is pre-laid and adjusted.

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] like Figures 1 to 3 As shown.

[0020] This application discloses a floating support structure for assisting in the construction of cables for a floating dual-head wind turbine, comprising:

[0021] A flange 4 is used for fixed connection with the pontoon 6. A lower structure 2 is fixed on the flange 4. A lifting beam 3 is fixedly connected to the top of the lower structure 2. Both ends of the lifting beam 3 extend to the outside of the top of the lower structure 2. There are lifting points 5 at both ends of the lifting beam 3. A winch wire rope 7 for temporarily restraining the lower end of the cable 8 is connected to the lifting points 5.

[0022] The upper structural frame 1 is fixed to the middle of the hanging beam 3, and the upper structural frame 1 has reinforcing arms 11 that reinforce the two ends of the hanging beam 3.

[0023] Working principle: When in use, the entire structure of the float support is lifted to the top of the float 6 by a crane. The flange 4 and the float 6 are fixedly connected with bolts and nuts. During installation, the lifting beam 3 and the lifting point 5 are aligned with the direction of the two side cables 8.

[0024] The pontoon support structure disclosed in this application enables the lower end of the cable 8 to be temporarily constrained at the point where the pontoon 6 is to be connected, thus solving the problem that the pontoon itself does not have the function of temporarily constraining the lower end of the cable when the cable is pre-laid and adjusted.
