Self-adaptive stable convection horizontal shaft tidal current energy water turbine

Abstract

The invention discloses a horizontal shaft tidal current energy water turbine with self-adaptive stable convection. The horizontal shaft tidal current energy water turbine comprises a power generation part, a self-adaptive stable convection structure part and a supporting structure part, the power generation part is connected with the supporting structure through the self-adaptive stable convection structure; the self-adaptive stable convection structure part comprises a generator support, a steering shaft, a convection limiting device, a tail rod and a tail vane. The generator support is fixedly connected with a generator. The other end of the steering shaft penetrates through an embedded bearing of the convection limiting device along the axis and is fixedly connected with the upper end of the tail rod; the lower end of the tail rod is fixedly connected with the tail vane; the supporting structure part comprises a U-shaped support, a vertical supporting column and a base. The U-shaped bracket is fixedly connected with the lower end of the convection limiting device; one end of the vertical pillar is connected with the U-shaped bracket, and the other end is connected with the base; the integral reversing problem of the water turbine can be effectively solved, the characteristics of simple structure principle, stable convection, high reliability and the like are achieved, and bidirectional tidal current energy can be efficiently captured.

Description

technical field [0001] The invention belongs to the technical field of tidal current power generation, and in particular relates to an adaptive and stable convection horizontal axis tidal current energy water turbine. Background technique [0002] With the continuous depletion of traditional fossil fuels, the relationship between energy supply and demand is becoming increasingly tense. About 71% of the earth is covered by oceans. The vast oceans contain rich mineral resources and huge ocean energy. Tidal current energy is a kind of marine renewable energy, which is stable, regular, unaffected by weather, easy to obtain and has huge reserves. As the core component of tidal current energy generation device to capture energy, hydro turbine is a research hotspot in the field of tidal current energy generation for its energy harvesting efficiency and reliability. The horizontal axis turbine has become one of the main forms of tidal current power generation devices in the world b...

Problems solved by technology

However, the turbine in this device cannot stabilize the convection, and its yaw will directly affect the energy-gaining efficiency of the turbine, and the up and down swing of the turbine and the tail rudder will increase the vibration of the entire device

In addition, the water turbine in this device can rotate 360° around the rotation axis, so there is a hidden danger of cable entanglement
