Description

Flowing water hydraulic generator

Technical field

The utility model relates to a kind of hydroelectric generator, particularly a kind of directed basin hydroelectric generator.

Background technique

At present, existing in the world known hydroelectric power all needs reservoir filling, requires to have the water drop of certain altitude, produces the powered water turbine with this, reaches to drive the effect that generator produces electric energy.For solving the problem of the retaining and the drop of flooding, before building such hydroelectric power plant, all to do a large amount of assessments, exploration, design and demonstration in advance usually.Dam to build in the dam construction and expend lot of manpower and material resources again, after being constructed and put into operation, ecotope often is subjected to heavy damage, and the profit and loss is difficult to divide so be still, the pros and cons coexistence.

The model utility content

The purpose of this utility model just is: providing a kind of can use in the water in directed basins such as rivers, is not subjected to the influence of running water level fluctuation, and the kinetic energy of flowing water is become electric energy by mechanical transmission, influence ecological environment neither, also wasting space not, invest lower, the hydroelectric generator faster of being benefited.

For solving the problems of the technologies described above, technological scheme provided by the utility model is:

A kind of flowing water hydraulic generator includes water wheels, generator, and it also comprises two columns that are built in the bottom, gearbox, lifting board; Described column is built in the flowing water and is higher than the height of the high water surface of flowing water flood season, is fixed on the flowing water bottom; Described water wheels are vertical water turbine, and water wheels wheel axle horizontal also is fixed with drive wheel on the wheel shaft, and the wheel shaft two ends are installed on the bearing support, and the two end axles bearing is fixedly mounted on respectively on two lifting boards, and the bottom of water wheels is positioned at below the water surface; Drive wheel in the gear of described gearbox and the water wheels rotating shaft and the engagement of the main shaft of generator; Gearbox and generator also are fixed on the lifting flat board, and two lifting boards are installed in respectively on the platform of two columns.

Described two column top opposed inside form platform to lower recess, and boss is then formed on the top of column, and the Placement of lifting board and column is for can produce the mode that is slidingly connected of Vertical direction relative displacement.

The mode of being slidingly connected of described lifting board and boss is the gear rack form, the draft of regulating water wheels by the height of regulating lifting board, to adapt to the different water level requirement of dry season and flood season, lifting board raises dry season, avoid the resistance of water-bed silt to water wheels, flood season then reduces lifting board, utilizes water resource fully.

Also include windshield, described being fixed on is positioned at before the water wheels and in the position of current upstream.

In rotating shaft place of water wheels, by gearbox the rotational velocity of water wheels rotating shaft is become suitable rotational velocity, drive generator for electricity generation.The electricity that a plurality of generators send, carry the use that networks of debarking by cable through series parallel connection and transformer transformation processing back.

According to the technological scheme that the utility model provides, it has following advantage with respect to prior art:

This power generating equipment is built in the rivers of nature flowing water, as long as the main channel of avoiding navigating, can not influence and navigate, more can land occupation, also without any pollution, and cost is low, technology content is not high, general private enterprise, medium-sized and small enterprises can both be invested, and this equipment can be built a plurality of before and after same waters, recycling water energy.Also can many scales that reach certain hydroelectric power plant in parallel according to waters flow and flow velocity degree situation, all can reach the effect of the kinetic energy generating that rationally makes full use of the waters of flowing.With regard to by the Changjiang river of nearly thousand kilometers from Yichang to Nanjing, under the situation that does not influence ship navigation and flood passage, also can build up hundreds of individual such small plants.The generating peak of this equipment is the abundance of water season in summer, autumn, and this is excessive for alleviating electricity consumption in summer breach, and certain benefit is also arranged.
