Vertical-axis runner propeller and hydrogen-producing ship using the same

Abstract

The invention discloses a vertical axis runner propulsor and a power generation hydrogen production ship using the same, comprising a vertical axis runner propulsor, a deflector, a buoy cabin liftingand lowering support device, a power generation system, a hydrogen production system and the like; The Hydrogen generator ship is the same in shape and small in volume as ordinary ship. The buoy cabinlifting and lowering supporting device can adjust the draught depth of the hull, adapt to various river conditions, and select different river sections for power generation according to the seasonalwater regime change. Vertical axis wheel propeller, concentrated and densely installed on the bottom of the ship, increase the installed capacity per unit area; The utility model is a lift-drag compound propeller, which is both a high-efficiency propeller and a high-efficiency hydraulic turbine, can run without additional power and driving device, and does not affect the power generation during running; The design of the air deflector not only increases the power generation capacity, but also does not occupy the space and affect the driving. The electricity generated is used to electrolyze water to produce hydrogen without grid connection and provides a stable source of hydrogen fuel for hydrogen fuel cell vehicles.

Description

technical field [0001] The invention relates to a vertical axis runner propeller and a power generation hydrogen production ship using the propeller, belonging to the technical field of new energy. Background technique [0002] As a clean energy source, hydropower has always been highly valued by the governments of various countries. However, hydropower stations need to dam the river, which requires a large investment and a long construction period, and is subject to many restrictions such as natural conditions of water sources and immigration. Can we use water resources to generate electricity without building dams? In April 2016, Sichuan Daily, Luzhou Daily and other domestic media and Sichuan News Network and other websites successively reported such a piece of news: the scientific research project of "Water Wheel Type Two-wheel Power Generation Ship" led by Luzhou Maritime Safety Administration, is in the After the Science and Technology Department of the Provincial Dep...

AI Technical Summary

Problems solved by technology

Although the ship has successfully used the natural water flow to generate electricity and successfully connected to the grid, the report also pointed out that it has the following defects and deficiencies: 1. The impeller is installed on the side of the ship, and the huge impeller is almost completely exposed to the water surface. Beautiful, but not safe, and it takes up a lot of space and has low operating efficiency

2. The speed of the impeller will change with the change of the water flow speed, which will cause the instability of the power generation voltage and frequency, and it will be difficult to meet the requirements of grid connection. To solve the problem of generator speed regulation, a lot of money needs to be invested, and the effect is difficult to achieve ideal

3. Multiple impellers are installed on both sides of the hull, and the front impeller will hinder the water flow velocity of the rear impeller, reducing the power generation efficiency and power of the rear impeller

4. At present, due to the horizontal rotation of the paddle wheel runner, the water flow blocked by it flows away from the lower part of the blade, and cannot do work on the blade of the hydraulic turbine behind. In the closed channel, the blade will completely block the channel; the same is true for the propeller , the blockage of the water flow by the rotating plane of its blades will cause the incoming water in the front to be blocked and diverted.

5. The power generated by the power generation ship needs to be transmitted to the substation on the shore through cables, and then input to the power grid after being transformed by the substation. In this way, additional investment in substations and transmission cables is required, and the power generation ship can only be anchored near the power station. Fixed water power station, not a real ship

In a fixed location, the water flow energy will inevitably decrease in the dry season, and it is impossible to ensure the maximum water flow energy throughout the year
