Embodiment Construction

[0021] The wave energy generating device utilizing the free pendulum energy harvesting of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The wave energy generating device utilizing the free pendulum to capture energy of the present invention is mainly composed of three subsystems: a wave energy capture system, an energy transmission system and an energy output conversion system.

[0023] like figure 1 and Figure 4 As shown, the wave energy capture system mainly consists of a swing rod 26, a spherical pendulum 27, a universal ball 25, an upper ball seat 29 and a lower ball seat 28. The lower end of fork 26 is fixedly connected with spherical pendulum 27. The pendulum 27 can be designed as a hollow floating ball or a solid ball structure, and the wave energy can be captured by the movement of the spherical pendulum 27 relative to the ocean platform. The universal ball 25 is fixedly connec...

Abstract

The invention belongs to the technical field of ocean resource development and utilization, and relates to a wave power generation device, in particular to a wave power generation device capable of harvesting energy by utilizing a free pendulum. The wave power generation device is mounted on a moving or fixed ocean platform, and comprises the following three parts which are connected in sequence:a wave energy harvesting system, an energy transmission system and an energy output conversion system, wherein the wave energy harvesting system is used for harvesting wave energy and converting the harvested wave energy into mechanical energy; the energy transmission system is used for flexibly and unidirectionally transmitting reciprocating mechanical motion to the energy output conversion system; and the energy output conversion system is used for converting the transmitted mechanical energy into electric energy. The wave power generation device capable of harvesting energy by utilizing thefree pendulum has the beneficial effects that not only can wave energy of different wave directions be efficiently harvested, but also the constant value of wave energy can be converted into electricenergy output; the whole system is high in energy utilization ratio, easy to maintain, and steady in electric energy output; and the wave power generation device can be applied to various ocean platforms for power generation.

Description

technical field [0001] The invention belongs to the technical field of marine resource development and utilization, and relates to a wave energy generating device. Background technique [0002] As a green renewable energy with large reserves and wide distribution, wave energy has become one of the research hotspots in the field of new energy. Due to the characteristics of poor stability, low frequency, and strong destructiveness of waves, the wave energy generation device has low power generation efficiency and poor reliability, which restricts the wide application of wave energy. The conversion of wave energy to electrical energy usually includes two stages. The first stage is to convert wave energy into mechanical energy with the help of wave energy conversion devices, and the second stage is to use various forms of generators to convert mechanical energy into electrical energy. The efficiency of wave energy conversion devices largely determines the efficiency of wave ene...
