Intelligent water turbine system with tail water flow flow-increasing device in chain line shape

Abstract

The invention relates to an intelligent water turbine system with a tail water flow flow-increasing device in a chain line shape. A through flow type water turbine generator set is included. The system is characterized in that the tail water flow flow-increasing device in the chain line shape and a tail water flow state controller are further included; the tail water flow flow-increasing device inthe chain line shape is formed in the manner that a force bearing induction unit, a flow-increasing transmission unit, a flow-increasing release unit and a rotating wheel unit, with rotating wheel blades in a chain line shape, in a chain line shape are sequentially arranged in parallel in the axial direction; the rotating wheel blades in the chain line shape gradually stretch in the axial direction of a rotating wheel hub in a chain line shape according to a chain line, and are uniformly arranged on the peripheral inner wall of the rotating wheel hub in the chain line shape in a space intersecting distorted shape; and the tail water flow state controller controls a blade angle beta1 of rotating wheel blades of the through flow type water turbine generator set, a blade angle beta2 of the rotating wheel blades in the chain line shape, and a moving distance x of an induction driving rod. The intelligent water turbine system with the tail water flow flow-increasing device in the chain line shape can sufficiently utilize lots of remaining kinetic energy in tail water flow of the through flow type water turbine generator set for power generation

Description

technical field [0001] The invention belongs to the technical field of hydroelectric power generation, in particular to an intelligent water turbine system with an interlocking linear tail water flow increasing device. Background technique [0002] my country is rich in low-head hydraulic resources, which are generally located in economically developed areas in the middle and lower reaches of rivers. In recent years, the economies of these regions have developed rapidly, and the demand for electricity has grown rapidly. However, these areas are generally energy-stressed areas, and the developable medium and high head hydropower resources have been developed as early as the 1990s. In order to meet the needs of rapid economic development in the region, people turned to develop low-head resources. Tubular hydropower stations are the best way to develop low-head hydraulic resources, and are generally used for water heads below 25m. Compared with medium and high water head pow...

Problems solved by technology

The device overcomes the existing problems of single power generation method and low power generation efficiency, and realizes high-power power generation

However, this device only relies on the curved deflector with a half-crescent shape in cross-section to divert and gather energy, and its energy gathering effect is minimal, so water energy cannot be fully utilized, resulting in a waste of resources

[0007] To sum up, the existing combined hydroelectric power generation devices are only the series connection of different numbers of power generation devices, without considering the problem of the reduction of device efficiency caused by the change of working conditions, so the maximum performance of the device cannot be fully utilized

At the same time, the energy-gathering device only relies on the reduction of the cross-sectional area to increase the flow, and cannot dynamically adjust the amount of flow increase according to the size of the incoming flow, resulting in variable frequency of output power and poor performance
