Problems solved by technology

Among these conversion systems, the oscillating water column type OWC is the most representative one. It uses air as the working medium to drive the runner, has relatively high peak efficiency, good starting performance, and is suitable for working under variable working conditions, etc. characteristics, but the average efficiency of this conversion system is relatively low, and the flow noise is relatively large

Embodiment 1

[0022] The present invention comprises an L-shaped body composed of a guide tube 1, a guide wheel tube 2 and a reservoir 3; the guide tube 1 is trumpet-shaped for capturing wave energy; The runner 4 that can be converted into electric energy and the guide body 5 for placing the engine unit. The outer wall of the runner hub 10 is evenly provided with a number of runner blades 11 along the circumference, and the outer wall of the guide body 5 is provided with a wave guide for guiding the wave to the runner. Several fixed guide vanes 6 on the blade 11 thereby drive the runner 4 to rotate; the reservoir 3 is cylindrical.

[0023] The guide body 5 includes a first hollow barrel 7 and a second hollow barrel 8, all of which are fixed in the guide wheel tube 2, and the runner 4 is arranged between the first hollow barrel 7 and the second hollow barrel 8; One end of the hollow barrel 7 and the second hollow barrel 8 is respectively fixed with a hemispherical top cover 9 . The runner b...

Embodiment 2

[0030] In this embodiment, the fixed guide vanes 6 adopt a pure flat plate shape without arc segments, and two sets of fixed guide vanes 6 are symmetrically divided in a figure-eight shape on both sides of the runner 4 . Others are the same as in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to a wave force direct-driving hydraulic turbine which comprises an L-shaped body composed of a flow-guiding pipe, a flow-guiding wheel pipe and a water storage tank. Fixed type flow-guiding blades, a rotating wheel for enabling wave energy to be converted into electric energy and a flow-guiding body for placing an engine block are arranged in the flow-guiding wheel pipe. A plurality of rotating wheel blades are evenly arranged on the outer side of the rotating wheel in a circumferential direction, and an outer wall of the flow-guiding body is provided with two groups of fixed type flow-guiding blades used for guiding waves to the rotating wheel blades so as to drive the rotating wheel to rotate. The flow-guiding pipe enables the waves to be collected into the hydraulic turbine, and the water storage tank has the effect of storing flow flowing through a hydraulic turbine passageway. Within a wave period, water flow flows in and out in the hydraulic turbine to form reciprocated water flow and always drives the rotating wheel to rotate towards the same direction. The wave force direct-driving hydraulic turbine integrates wave energy capture and conversion, is simple in structure and convenient to install and maintain, has a wide high-efficiency area, and is high in adaptability to wave height changes.

Description

technical field [0001] The invention relates to a water turbine, in particular to a wave force direct drive water turbine. Background technique [0002] In order to meet the needs of human beings for energy, it is a very important task for governments to develop low-carbon economy and actively develop renewable energy. How to obtain renewable energy from the ocean, which covers more than 70% of the earth's area, has become the focus of the energy industry. Among them, wave energy is the highest-grade ocean energy because the development process has little impact on the environment and exists in the form of mechanical energy. It has huge reserves and wide distribution. It is the main direction of future ocean energy utilization and development. It will play a role in ocean development and coastal defense. Key role. The use of wave energy to generate electricity can provide clean energy for remote islands and offshore facilities. It can also use the power provided by wave en...
