Problems solved by technology

The traditional method is to use rigid or semi-rigid connectors such as welding and hinges to connect modules, but this often leads to stress concentration and the structure is difficult to withstand
However, the use of flexible connectors will cause smoothness cannot be guaranteed due to the release of relative movement between floating bodies
At the same time, there is no storage space on the existing ultra-large floating platform, which cannot meet the basic loading function requirements

Embodiment 1

[0042] Such as Figure 1-7 As shown, a floating platform that can utilize wave energy to generate electricity includes a plurality of buoyant modules 2 that are sequentially connected end to end. The decks 22 of the two floating body modules 2 are connected through a wave energy conversion device. Each deck 22 is correspondingly provided with an operating platform 1 directly above. The operating platform 2 is a hollow box-shaped structure used as a storage space.

[0043] Adjacent operating platforms 1 are rigidly hinged, and a rubber spring 4 is provided between the operating platforms 1 and the floating body module 2 . The rubber spring 4 is formed by alternately stacking multiple layers of rubber and steel plates. A plurality of viscous dampers 7 are arranged longitudinally and transversely between the deck 22 and the operating platform 1 . The viscous damper 7 includes a double-rod piston cylinder 72 and support seats 71 respectively connected to the two ends of the do...

Embodiment 2

[0059] Such as Figure 8 As shown, embodiment 1 is repeated, the difference is that a set of wave energy conversion device only includes one power generation device 6, and a plurality of hydraulic cylinders 5 arranged in parallel, and the rod chambers between the hydraulic cylinders 5 arranged in parallel correspond to each other in sequence Connected, the rodless cavity is connected in sequence correspondingly, and multiple hydraulic cylinders 5 share a power generating device.

Embodiment 3

[0061] Such as Figure 9 As shown, repeating Example 1, the difference is: multiple sets of wave energy conversion devices are arranged side by side, the number of hydraulic cylinders 5 is the same as the number of power generation devices 6, and one hydraulic cylinder 5 corresponds to a set of power generation devices 6, and the hydraulic cylinders arranged in parallel The rod cavities between 5 are correspondingly connected in sequence, and the rodless cavities are correspondingly connected in sequence.

[0062] The rod chamber and the rodless chamber are connected in sequence to ensure that the pressure of all the rod chambers of different hydraulic cylinders 5 is the same, and the pressure of all the rodless chambers is the same, so as to ensure that the forces on each hydraulic cylinder 5 are equal, and avoid the damage caused by the multi-degree-of-freedom movement of the floating body. Different hydraulic cylinders 5 are unevenly stressed and cause individual cylinders ...

Abstract

The invention discloses a floating platform capable of generating power through wave energy. The floating platform comprises a plurality of floating body modules connected sequentially end to end. The floating body modules comprise buoyancy supporting pieces and decks arranged on the tops of the buoyancy supporting pieces; the decks of every two adjacent floating body modules are connected through a flexible connector, and a wave energy conversion device is arranged between the decks of every two adjacent floating body modules; the wave energy conversion devices are composed of hydraulic oil cylinders and power generating devices; an operation platform is arranged over each deck, and every two adjacent operation platforms are hinged rigidly; and a plurality of viscous dampers and rubber springs are arranged between the decks and the operation platforms. The floating platform is good in smoothness and large in storage space and can be used as the multifunctional platform such as an airplane take-off and landing platform, a deep sea relaying wharf and a resource development and utilization foundation. After a wave energy absorption device is additionally arranged, on one hand, pitching and heaving responses of floating bodies can be effectively restrained, and the overall stability of the operation platforms is improved, and on the other hand, the wave energy can be used for power generating.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a floating platform capable of generating electricity by using wave energy. Background technique [0002] With the expansion of the earth's population and the overexploitation of land resources, countries around the world have shifted their economic development focus to the ocean. Very Large Floating Structure (VLFS for short) is a new type of high-end marine engineering equipment based on the strategic needs of national marine rights protection and deep-sea resource development. It can be used as an open-sea rapid transportation hub, a large-scale deep-sea development and operation platform, an ocean-going material storage relay station, and a comprehensive military platform for rapid response to maneuvering at sea. [0003] Due to the huge size of the ultra-large floating structure, it is destined to adopt a modular assembly structure in terms of construction, tra...
