[0016] Another object of the present invention is to provide a method for installing an underwater circular foundation, comprising the following steps:

[0017] S1. Place the underwater circular foundation in the guide hole.

[0018] S2. The guide hole adjustment device drives the straightening plate to approach the axis of the guide hole, and the straightening plate contacts the wall surface of the underwater circular foundation.

[0023] S7, the guide hole adjustment device drives the straightening plate away from the axis of the guide hole, and the straightening plate is separated from the surface of the underwater circular foundation;

[0024] S8. Recover and install the righting equipment.

[0025] Compared with the prior art, the beneficial effects of the underwater circular foundation installation and straightening device described in the present invention are mainly reflected in: guiding the circular foundation through the guide hole to achieve the straightening of the circular foundation; thereby preventing the circular foundation from tilting relative to the installation and straightening device during the installation process. A locking device is provided to lock the underwater circular foundation, and the underwater circular foundation is locked through the locking device; in this way, when installing the underwater circular foundation, the underwater circular foundation can be first fixed on the straightening device, and then the straightening device and the underwater circular foundation can be moved to the seabed together, avoiding the uneven force caused by the assembly of the underwater circular foundation and the installation and straightening device in seawater, and at the same time, it can reduce the difficulty of matching between the underwater circular foundation and the installation and straightening device, which is convenient to use.

[0026] The locking mechanism moves along the radial direction of the guide hole, so that when the locking mechanism is close to the guide hole, the locking mechanism abuts against the wall of the underwater circular foundation, and the symmetrically arranged locking mechanism locks the underwater circular foundation; when the locking mechanism is away from the guide hole, the locking mechanism separates from the wall of the underwater circular foundation, thereby unlocking the underwater circular foundation.

[0027] In the locking device, the locking fixing nut is fixedly connected to the support frame, and the rotating locking adjustment bolt moves relative to the locking fixing nut; the locking adjustment bolt is rotated to adjust the distance between the locking adjustment bolt and the wedge block; when the locking adjustment bolt abuts against the wedge block, the locking adjustment bolt is pushed to move toward the guide hole by continuing to rotate the bolt to adjust the locking adjustment bolt, so that the wedge block is close to the underwater circular foundation; this structure is simple; the wedge block is supported by the second fixed groove while guiding the movement of the wedge block. At the same time, the locking adjustment bolt and the wedge block are separately arranged, and then under the push of the locking adjustment bolt, the wedge block realizes horizontal linear movement, which can prevent the wedge block from rotating on the horizontal circular foundation and causing wear on the wall surface of the horizontal circular foundation.

[0028] The wedge block can be reset by setting an unlocking device in cooperation with the wedge block; when the locking and adjusting bolt moves close to the guide hole and the driving wedge block, the reset spring is stretched, and then when the locking and adjusting bolt moves away from the guide hole and separates from the wedge block, the stretching force of the driving reset spring disappears, and the reset spring retracts under the action of its own elastic force, thereby driving the wedge block to reset and realize the separation of the wedge block from the underwater circular foundation; by setting an unlocking device, the locking and adjusting bolt and the wedge block do not need to be connected, and the reset of the wedge block can be achieved, and the structure is simple.

[0029] In the contact end surface, the bite force between the contact end surface and the underwater circular foundation is increased by arranging the contact convex surface and the contact concave surface, thereby improving the locking effect of the locking device on the underwater circular foundation.

[0030] In the righting device, the righting fixing nut is fixedly connected to the support frame, the rotating righting adjustment bolt moves relative to the righting fixing nut, and the righting adjustment bolt is used to drive the righting plate to approach or move away from the guide hole; the position of the righting plate is adjusted by rotating the righting adjustment bolt, when multiple righting plates approach each other, the guide hole shrinks; when multiple righting plates move away from each other, the guide hole expands; thus, the size of the guide hole is adjusted according to the diameter of the underwater circular foundation. The righting plate is supported by the first fixing groove while guiding the movement of the righting plate.

[0031] A guide inclined plate is arranged on the straightening plate, and the guide inclined plate is arranged to be inclined upward and outward relative to the guide belly, so that the space at the entrance of the guide hole is increased, and the assembly of the underwater circular foundation and the guide hole is convenient.

[0032] By arranging lifting ears on the support frame, it is convenient to hoist the installation and straightening equipment; by arranging a level meter to detect the levelness of the straightening equipment, it can be ensured that the levelness of the underwater circular foundation is within a preset range when it is installed in place.

[0033] By setting the bottom plate, the contact area between the support frame and the seabed is increased, the supporting effect of the support frame is improved, and then the stability of the installation of the righting device on the seabed is improved; at the same time, the underwater circular foundation is avoided by setting the openings to avoid interference when the installation righting device is separated from the underwater circular foundation; in this way, after the underwater installation foundation is installed in place, the righting device is lifted along the height direction of the underwater installation foundation to facilitate the installation and separation of the righting device from the underwater installation foundation.

[0034] The present invention locks the underwater circular foundation assembled in the installation and righting device by cooperating with the locking device and the righting device, so that the installation and righting device and the underwater circular foundation can be moved to the seabed together, avoiding uneven force caused by assembling the underwater circular foundation and the installation and righting device in seawater, and at the same time reducing the difficulty of coordination between the underwater circular foundation and the installation and righting device, making it convenient to use.

[0035] Compared with the prior art, the beneficial effects of the underwater circular foundation installation method described in the present invention are mainly reflected in: a locking device is set to lock the underwater circular foundation, and the locking device limits the movement of the underwater circular foundation relative to the underwater circular foundation, so that the underwater circular foundation can be first assembled on the installation and righting equipment; and then the underwater circular foundation and the installation and righting equipment are hoisted to the seabed; the underwater circular foundation can be prevented from being affected by the marine environmental load during assembly, thereby reducing the difficulty of assembly between the underwater circular foundation and the installation and righting equipment.
