Description

Technical Field

[0001] The utility model relates to the technical field of buoy mooring, in particular to a mooring device for offshore floating bodies. Background Art

[0002] In recent years, with the increasing demand for energy, the development of marine resources has gradually increased, such as the exploitation of oil and natural gas and the use of offshore wind energy. Offshore floating bodies have been widely used in the fields of marine resource development, offshore aquaculture, floating platforms, etc. In order to ensure the stability and safety of floating bodies in the offshore environment, the design of mooring devices is crucial.

[0003] The anchoring method of traditional mooring devices mainly relies on anchor chains and anchor piles, and the floating body is fixed on the sea by anchor chains. However, under the influence of wind, waves or tides, the floating body will shake violently, thereby pulling the anchor piles through the anchor chains. In addition, under long-term severe sea conditions, the anchoring strength is often insufficient, which can easily cause the anchor piles to loosen or fall off from the ground. Professional equipment and technicians are required for regular inspection and maintenance, which is costly and has a long cycle. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the above problems and / or the problems existing in the prior art, the present utility model is proposed.

[0006] Therefore, the technical problem to be solved by the utility model is that the existing mooring device has a high risk of anchor failure under severe sea conditions.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a mooring device for an offshore floating body, comprising an anchor pile, the top of the anchor pile is fixedly connected to a mooring cable, the right end of the mooring cable is fixedly connected to a counterweight block, an elastic component is arranged inside the counterweight block, the right end of the elastic component is fixedly connected to an anchor chain, and the right end of the anchor chain is fixedly connected to a floating body.

[0008] As a preferred solution of the mooring device for offshore floating bodies described in the utility model, the bottom end of the anchor pile is buried deep underground, and the floating body floats on the sea surface.

[0009] As a preferred solution of the mooring device for offshore floating body described in the utility model, the elastic component includes a first iron sheet, the right end of which is fixedly connected to a telescopic spring, and the right end of the telescopic spring is fixedly connected to a second iron sheet.

[0010] As a preferred solution of the mooring device for offshore floating bodies described in the utility model, a telescopic slot is opened inside the counterweight block, a limiting slot is opened on the left side of the telescopic slot, and openings are opened at the top of the telescopic slot and the limiting slot.

[0011] As a preferred solution of the mooring device for offshore floating bodies described in the utility model, the first iron sheet is slidably connected in the limiting groove, the telescopic spring is arranged in the telescopic groove, and the second iron sheet is arranged outside the counterweight block.

[0012] As a preferred solution of the mooring device for offshore floating bodies described in the utility model, a sealing plate is slidably connected in the opening, a hand grip groove is provided on the upper surface of the sealing plate, and the sealing plate is arranged above the elastic component.

[0013] As a preferred solution of the mooring device for offshore floating bodies described in the utility model, the counterweight block is a solid iron block except for the telescopic slot, the limit slot and the opening on the top.

[0014] The beneficial effects of the utility model are as follows: in the device, a counterweight is added between the anchor pile and the anchor chain. When the sea waves are strong and the floating body shakes violently, generating a large pulling force on the anchor chain, the counterweight can be firstly subjected to the pulling force of the anchor chain, and the pulling force will not directly affect the stability of the anchor pile. Only when the pulling force is greater than the gravity of the counterweight and the dragging counterweight also shakes, will the pulling force affect the anchor pile. The design of this section plays a buffering role, which can effectively reduce the impact load of the floating anchor chain system and significantly improve the tensile strength of the entire mooring system.

[0023] Example

[0024] Reference Figures 1 to 3 The present embodiment provides a mooring device for an offshore floating body, comprising an anchor pile 1, a mooring cable 2 is fixedly connected to the top of the anchor pile 1, a counterweight 3 is fixedly connected to the right end of the mooring cable 2, an elastic component 4 is arranged inside the counterweight 3, an anchor chain 5 is fixedly connected to the right end of the elastic component 4, and a floating body 6 is fixedly connected to the right end of the anchor chain 5, wherein the anchor pile 1 is deeply buried underground and is a fixed point in the entire mooring system, and the counterweight 3 is placed above the ground and fixedly connected to the anchor pile 1 through the mooring cable 2, which can effectively enhance the impact load of the system and significantly improve the tensile strength of the entire mooring system, an elastic component 4 is also arranged inside the counterweight 3, the right end of the elastic component 4 is fixedly connected to the floating body 6 through the anchor chain 5, and the floating body 6 is fixed on the sea surface by the anchor chain 5, when the floating body 6 drives the anchor chain 5 to generate tension on the counterweight 3, the elastic component 4 can first play a buffering role.

[0025] Specifically, the elastic component 4 includes a first iron sheet 401, the right end of the first iron sheet 401 is fixedly connected to a telescopic spring 402, the right end of the telescopic spring 402 is fixedly connected to a second iron sheet 403, and a telescopic slot 301 is opened inside the counterweight 3, a limiting slot 302 is opened on the left side of the telescopic slot 301, and openings 303 are opened at the tops of the telescopic slot 301 and the limiting slot 302, and the first iron sheet 401 is slidably connected in the limiting slot 302, the telescopic spring 402 is arranged in the telescopic slot 301, and the second iron sheet 403 is arranged outside the counterweight 3.

[0026] It should be noted that, in the elastic component 4, the first iron sheet 401 is fixed in the limiting groove 302, and the second iron sheet 403 is arranged outside the counterweight block 3, and the right end of the second iron sheet 403 is fixedly connected to the anchor chain 5, so that when the anchor chain 5 generates a rightward pulling force, it can pull the second iron sheet 403 to move rightward, and the second iron sheet 403 can drive the telescopic spring 402 to stretch to the right, and the first iron sheet 401 is equivalent to being integrated with the counterweight block 3. Only when the telescopic spring 402 is stretched to the limit, the pulling force is It will drag the counterweight block 3 to cause shaking or movement. Therefore, through the elastic component 4, under the action of wind, waves or tides, the tension of the entire mooring system will be increased. When the tension is too large, the telescopic spring 402 will be pulled out from the counterweight block 3 to play a buffering role, which can effectively reduce the impact load of the mooring system and significantly improve the tensile capacity of the entire mooring system; when the tension is reduced, the second iron sheet 403 and the anchor chain 5 will be pulled back under the action of the rebound force of the telescopic spring 402, reducing the occupied area of ​​the sea and facilitating the navigation of passing ships.

[0027] Furthermore, a sealing plate 304 is slidably connected in the opening 303, a hand-grip groove is provided on the upper surface of the sealing plate 304, and the sealing plate 304 is arranged above the elastic component 4.
