[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] See also Figure 1 to Figure 4 The embodiment of the present application provides a marine anchoring device, including a box body 1, a telescopic rod 2 and an anchor pile 4, wherein the box body 1 has a preset weight and can serve as the gravity basis of the marine anchoring device, that is, most of the weight of the marine anchoring device is concentrated on the box body 1 itself. For example, when designing the marine anchoring device, the weight proportion of the box body 1 can be set to 70% to 80%. The bottom of the box body 1 is dispersedly provided with a plurality of through holes, and the telescopic rod 2 and the anchor pile 4 are arranged one by one in correspondence with the through holes. There are multiple options for the dispersion of the through holes, such as in Figure 2 In the dispersed form shown, this embodiment provides five anchor piles 4 distributed in a plum blossom lattice, that is, one anchor pile 4 is located in the center, and the remaining four anchor piles 4 are evenly distributed around the central anchor pile 4. The size of the through hole at the bottom of the box body 1 should be able to allow the anchor piles 4 to pass through.

[0029] The telescopic rod 2 is vertically arranged in the box 1 and aligned with the through hole. The telescopic rod 2 includes a fixed rod and a movable rod. The movable rod can slide relative to the fixed rod to achieve the extension and shortening of the telescopic rod 2. In the initial state, the telescopic rod 2 is in a shortened state. The upper end of the fixed rod is fixedly connected to the top of the box 1, and the lower end of the movable rod is provided with an electric control system 3. The electric control system 3 includes a body 31 fixedly connected to the movable rod and a rotating body 32 rotatably connected to the body 31. The rotating body 32 is driven by electricity to rotate around the axis of the movable rod. When the offshore anchoring device is a small or medium-sized anchor, a power supply system can be installed inside the box 1 to provide power; when the offshore anchoring device is a large anchor, power can be provided by adopting an external power supply, that is, a power supply system can be set outside the box 1 to provide more power. In addition, power can also be transmitted to the electric control system 3 by the power supply system on the sea surface through a cable. The rotating body 32 can specifically be the output shaft of the motor, or it can be a driven member connected to the output shaft of the motor. The power supply system transmits power to the motor, and the rotating body 32 rotates under the drive of the motor. The lower end of the fixed rod and the lower end of the movable rod are connected by a locking pin driven by the electronic control system 3. That is to say, in the initial shortened state, the fixed rod and the movable rod are connected by the locking pin to restrict relative sliding of the two, but this locking pin can be unlocked by the electronic control system 3. Specifically, an electromagnetic armature can be used to adsorb the locking pin to change the position of the locking pin, thereby achieving unlocking, or an electric push rod can be used as the locking pin.

[0030] The upper end of the anchor pile 4 is fixedly connected to the rotating body 32, so the anchor pile 4 rotates with the rotating body 32. The outer surface of the anchor pile 4 is provided with a thread structure, such as Figure 4 As shown, the anchor pile 4 includes an anchor core 41 and a thread 42 located on the surface of the anchor core 41. When the electric control system 3 releases the restriction of the upper locking pin between the fixed rod and the movable rod of the telescopic rod 2, the movable rod can slide downward relative to the fixed rod, and the electric control system 3 drives the anchor pile 4 to rotate, and the rotating anchor pile 4 drills into the soil, and uses the thread 42 to increase the contact area with the soil, thereby improving stability and pull-out bearing capacity.

[0031] The offshore anchoring device provided in the present application uses a box body 1 with appropriate weight as an anchoring foundation sunk to the seabed on the one hand, and drives the anchor pile 4 to rotate through the electric control system 3 to drill into the seabed to achieve enhanced anchoring, so that the offshore anchoring device can anchor offshore facilities more reliably.

[0032] like Figure 3As shown, in this embodiment, the rotating body 32 is located in the inner cavity of the main body 31, and a compression spring 5 is arranged between the top of the rotating body 32 and the top surface of the inner cavity. The compression spring 5 can increase the downward rebound force. When the rotating body 32 rotates and drives the anchor pile 4 to rotate and drill downward into the soil, the compression spring 5 can provide a downward force to facilitate drilling the anchor pile 4 into the soil. In order to improve the connection strength between the rotating body 32 and the anchor pile 4, the present application preferably makes the rotating body 32 cap-shaped, and the top end of the anchor pile 4 extends into the cap cavity of the rotating body 32 and is riveted and connected by the edge of the rotating body 32.

[0033] In order to further improve the soil drilling ability of the anchor pile 4, the present application can make the lower part of the anchor pile 4 conical, such as Figure 4 As shown, the anchor pile 4 in this embodiment includes a lower anchor cone 43. It should be noted that, Figure 4 It is only exemplarily shown that the thread 42 is arranged above the anchor cone 43 . In other embodiments, the thread 42 may extend from top to bottom to the surface of the anchor cone 43 .

[0034] like Figure 1 As shown, the shape of the box 1 can have a variety of options, for example, the cross-section of the box 1 is rectangular, circular or elliptical. The box 1 is generally welded from steel structural parts. In order to save steel, the weight requirement can be achieved by adding counterweights. For example, the present application can set a cylindrical enclosure corresponding to the through holes in the box 1, the lower end of the enclosure is connected to the bottom surface of the box 1 and surrounds the corresponding through holes, and a receiving space is formed between the outer surface of the enclosure and the inner surface of the box 1, and the receiving space is provided with a counterweight. Specifically, the counterweight can be concrete or pebbles. In order to facilitate remote control on the sea surface, the present application can set the electric control system 3 with a wireless transceiver module, that is, remote control is achieved through wireless signals. Of course, the electric control system 3 can also be connected to the controller on the sea surface through a cable.

[0035] The present application also provides an offshore anchoring method using the offshore anchoring device provided by the present application, which mainly includes the following steps: first, the equipment pre-built on the sea surface is connected to the box 1 of the offshore anchoring device through a rope, and after being transported to a designated position at sea, the box 1 is hoisted and thrown into the sea; then, after the box 1 sinks to the seabed, the electric control system 3 of the offshore anchoring device drives the locking pin to unlock, and at the same time drives the anchor pile 4 to rotate, and the anchor pile 4 is drilled into the seabed to enhance the anchoring.

[0036] The equipment constructed on the sea surface can be facilities of offshore photovoltaic projects, such as photovoltaic panels, etc., or facilities of offshore wind power projects, such as offshore windmills, etc. The rope connecting the box 1 and the equipment on the sea surface should have sufficient strength, and is generally a steel cable. When the height of the box 1 is large enough, the equipment on the sea surface can also be directly installed on the top surface of the box 1, that is, the offshore anchoring device is erected under the sea surface and is close to or above the sea surface. The top surface of the box 1 provides an installation platform, and the facilities or equipment to be installed on the sea surface are directly fixed to this installation platform.

[0037] In order to prevent the box body 1 from being greatly deflected during the anchoring process, the anchor piles 4 can be driven one by one in a cycle when implementing the offshore anchoring method, that is, only one anchor pile 4 rotates at the same time. Of course, it is also possible to control the drilling speed of the anchor piles 4 at different positions, so as to achieve a similar effect of driving one by one when multiple or even all anchor piles 4 are drilled at the same time, thereby ensuring that the anchoring foundation, i.e., the box body 1, is stable.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
