Base type tide power generator

Abstract

The invention provides a base type tide power generator which mainly comprises an impeller, a machine cabin and a pile support part, wherein the pile support part comprises a vertical pipe, a sleeve pipe, a connecting frame and a gravity sinking box, wherein the sleeve pipe is sleeved outside the vertical pipe, the connecting frame is connected to the sleeve pipe, the gravity sinking box is arranged on the connecting frame, a brake, an accelerator, a signal sensor, a signal wire and a generator are arranged in the machine cabin, a brake press button is arranged outside the machine cabin, a rotating shaft of the generator is connected with an impeller shaft through the accelerator, the brake is arranged on the impeller shaft, the signal sensor is arranged on the rotating shaft of the generator and controls the brake through the signal wire, the impeller and the machine cabin are arranged in a flow guide cover, and the flow guide cover is arranged on the vertical pipe. The base type tide power generator better starting and power generating performance, self adaptability on the tide flowing direction and simple structure, is convenient to install and use, has low manufacture, construction and operation cost, does not influence the shipping, is suitable for being used in shallow sea regions with rich tide energy, and can provide production and living electricity for residents in coastal areas and on islands.

Description

technical field [0001] The invention relates to a hydraulic machine and a hydraulic generator. Specifically, it is a high-performance bottom-mounted tidal current power generation device. Background technique [0002] Worldwide, the increasing shortage of energy and the continuous deterioration of the environment have prompted countries around the world to accelerate the development and utilization of green energy. As a green renewable energy, trend energy has the characteristics of high energy density, strong predictability, and abundant reserves. It is becoming more and more more and more attention from all over the world. [0003] At present, many R&D institutions or companies in the world have participated in the research of tidal current energy technology. Among them, the development and utilization of tidal current energy technology in the UK is at the forefront of the world, and a commercial-scale tidal current energy power station is under construction. my country...

AI Technical Summary

Problems solved by technology

However, the existing pile-based power generation devices also have problems such as difficult construction, high engineering cost, damage to the sea environment, and impact on shipping.

Compared with the vertical-axis tidal current power generation device, the technology of the horizontal-axis tidal current power generation device is relatively mature, and has the characteristics of high energy utilization rate and small mechanism vibration. However, the existing horizontal-axis tidal current power generation device also has the problems of poor start-up performance and adaptability to the flow direction.
