Spherical pendulum direct drive type wave power generation device

Abstract

The invention discloses a spherical pendulum direct drive type wave power generation device which comprises a spherical case, a supporting frame, a plurality of sets of floating plates, a mooring rope, a seabed weight, an internal case device and a generating mechanism. The spherical case is connected with the seabed weight through the mooring rope. The floating plates are fixedly welded to the periphery of the exterior of the spherical case. The two ends of the internal cabin device are fixedly connected with the spherical case through the supporting frame. The whole device can collect wave power in different directions under the inertia effect of a heavy punch, and the vertical reciprocating motion of waves can be converted into the single-direction rotating motion of a rotating shaft, so that a permanent magnet generator is driven to generate electricity. The wave power generation device can collect the wave power in the different directions and is high in wave power conversion efficiency, all energy conversion and transmission devices are arranged in the sealed spherical case and do not make contact with seawater, and therefore seawater corrosion is prevented, the corrosion resistance is high, and transporting, installing and debugging are convenient.

Description

technical field [0001] The patent of the present invention belongs to the technical field of marine clean energy utilization, and in particular relates to a spherical pendulum direct-drive wave energy generating device. Background technique [0002] The wave energy in the ocean is widely distributed and has a high energy flow density, which is a clean and renewable energy source. Large-scale and effective collection of wave energy will be the development direction of wave energy utilization devices in the future. According to whether the main body of the wave energy utilization device at home and abroad moves or not, it can be divided into two types: fixed type and floating type. At present, floating wave energy generation devices generally use external movable structures to collect wave energy. The movable parts are exposed to the marine environment, which makes the device vulnerable to seawater corrosion, short power generation life, and difficult transportation, assembly...

AI Technical Summary

Problems solved by technology

At present, floating wave energy power generation devices generally use external movable structures to collect wave energy. The movable parts are exposed to the marine environment, which makes the device vulnerable to seawater corrosion, short power generation life, and difficult transportation, assembly and maintenance.

In addition, the existing floating wave energy generation devices are generally greatly affected by the direction of wave transmission. If the wave energy collection device is not aligned with the direction of wave transmission during actual operation, the efficiency of wave energy collection and conversion will be seriously affected.
