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 ca

Example Embodiment

[0041] Example 1

[0042] like Figures 1 to 7 As shown in the figure, a floating platform that can use wave energy to generate electricity includes a plurality of floating body modules 2 connected end to end in sequence. The decks 22 of the two floating body modules 2 are connected by a wave energy conversion device. The operating platform 1 is correspondingly provided directly above each deck 22 . The operating platform 2 is a hollow box-shaped structure and is used as a storage space.

[0043] The adjacent operating platforms 1 are rigidly hinged, and a rubber spring 4 is provided between the operating platform 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 provided longitudinally and laterally between the deck 22 and the operating platform 1 . The viscous damper 7 includes a double-rod piston cylinder 72 and a support seat 71 which is respectively...

Example Embodiment

[0058] Example 2

[0059] like Figure 8 As shown, Example 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 cavities between the hydraulic cylinders 5 arranged in parallel correspond to each other in sequence. The rodless chambers are connected in sequence, and a plurality of hydraulic cylinders 5 share a power generation device.

Example Embodiment

[0060] Example 3

[0061] like Figure 9 As shown, Example 1 is repeated, the difference is: the wave energy conversion devices are provided with multiple sets in parallel, the number of hydraulic cylinders 5 is the same as the number of power generation devices 6, one hydraulic cylinder 5 corresponds to a set of power generation devices 6, and the hydraulic cylinders arranged in parallel The cavities with rods between 5 are communicated in sequence, and the cavities without rods are communicated in sequence.

[0062] Corresponding communication between the rod cavity and the rodless cavity can ensure that the pressures of all rod cavities of different hydraulic cylinders 5 are the same, and that of all rodless cavities are the same. The uneven force on different hydraulic cylinders 5 leads to the damage of 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...
