Kinetic and potential energy combined wave power generating device

Abstract

The invention discloses a kinetic and potential energy combined wave power generating device. The kinetic and potential energy combined wave power generating device comprises a body, a rolling bearing rotatably arranged in the body, a spindle axially and movably inserted in the rolling bearing, an impeller connected to the outer end of the spindle and used for driving the spindle to rotate under the impact of waves, a magnetic drive mechanism used for driving the rolling bearing to rotate synchronously under rotation of the spindle, a potential energy generating mechanism used for generating by the aid of the relative axial position between the spindle driven by variation of water level and the rolling bearing and a kinetic energy generating mechanism used for generating by the aid of rotating movement of the rolling bearing. By the arrangement, the kinetic energy of the waves can be converted into electric energy through the kinetic energy generating mechanism, the potential energy generated from variation of water level of the sea surface can be converted in to the electric energy through the potential energy generating mechanism, utilization styles of the energy contained in the waves are expanded, utilization rate of the wave energy is increased, negative brought by the variation of the water level of the waves is eliminated, and meanwhile, generating efficiency and economical efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of hydroelectric power generation, in particular to a kinetic potential energy combined ocean wave power generation device. Background technique [0002] With the rapid growth of my country's economy, people's dependence on energy is gradually increasing. [0003] Fossil energy occupies a large proportion of the energy used by people. However, the massive use of fossil energy has had a serious impact on our living environment and poses a threat to people's life and health. Therefore, some people began to increase the development and utilization of new renewable energy. Among the new renewable energies developed by people, hydropower resources are a new type of energy with abundant reserves and great application prospects. In addition, my country is rich in hydropower resources, both in terms of reserves and exploitable hydropower resources, ranking first among all countries in the world. In my country's h...

Problems solved by technology

In the prior art, marine power generation equipment generally generates power through the kinetic energy of sea waves at high tide or low tide, and can only use the kinetic energy of sea waves. The problems are mainly manifested in the following aspects: 1. The utilization mode of marine development hydraulic resources equipment is single; 2. The water surface fluctuates greatly near the coast in the ocean, and power generation equipment is easily affected by changes in water level

In this way, it is easy to lead to low power generation efficiency and poor economy
