Water circulation tidal current generation simulation device

Abstract

The invention relates to a water circulation tidal current generation simulation device, which comprises a box body and a water circulation pipeline connected with the box body. The water circulationpipeline is provided with a flow observation instrument and a water pressure gauge, and a water pump is installed on a drainage pipe. A lower bearing seat is fixedly installed in the box body; an upper bearing seat is fixedly installed on the top cover of the box body; a tidal current energy blade group is installed between the upper bearing seat and the lower bearing seat, and a flow meter and awater depth measuring ruler are installed in the box body. The top end of a main shaft is connected with a lower coupling, the top of the lower coupling is provided with a speed increaser; the top ofthe speed increaser is connected with an upper coupling, and the upper coupling is coaxially connected with a generator. The simulation device provided by the invention can simulate the power generation of the tidal current truly, and replace the sea trial to be carried out by collecting various experimental data; the experiment cost is greatly saved; the simulation device provided by the invention has small volume and can be placed in a laboratory to study the tidal current power generation of vertical blades; and various test data acquisition and blade improvement are convenient.

Description

technical field [0001] The invention relates to a water circulation tidal current power generation simulation device, which belongs to the technical field of ocean energy power generation simulation equipment. Background technique [0002] Ocean energy refers to the renewable energy attached to seawater. The ocean receives, stores, and emits energy through various physical processes. These energies exist in the ocean in the form of tides, waves, temperature differences, salinity gradients, and ocean currents. Ocean energy is clean and renewable, has large reserves, is widely distributed, and has little impact on the environment. Therefore, it is a new energy source with strategic significance that needs to be developed urgently. The prospects for the development of global ocean energy resources are very promising. [0003] With the consumption of non-renewable energy such as oil and coal, people gradually consider how to make full use of the energy on the ocean, and the tid...

Problems solved by technology

However, the energy conversion rate of the tidal current power generation device is low, and a more comprehensive research plan is needed. During the research process, it is necessary to test the influence of factors such as water flow velocity, water depth, pressure, flow rate, and blade structure on the power generation conversion rate.

However, the real sea trial needs to go to the sea to build a site, install and transport equipment, which is time-consuming and expensive, and it is extremely difficult to implement. At this time, a simpler and more practical test device is needed, which can conduct preliminary verification of the designed device in the laboratory and experimental calculations
