Intelligent water turbine system with gold spiral tail waterflow increasing device

Abstract

The invention relates to an intelligent water turbine system with a gold spiral tail waterflow increasing device. The intelligent water turbine system comprises a cross-flow water turbine-generator set, and is characterized by further comprising the gold spiral tail waterflow increasing device and a tail waterflow state controller, wherein the gold spiral tail waterflow increasing device is composed of a stress sensing unit, a flow increasing transmission unit, a flow increasing release unit and a gold spiral rotating wheel unit with gold spiral rotating wheel blades, which are sequentially and parallelly arranged in the axial direction; the gold spiral rotating wheel blades gradually stretch in the axial direction of a gold spiral rotating wheel hub according to a gold spiral, and are uniformly arranged on the circumferential inner wall of the gold spiral rotating wheel hub in a space cross distortion shape; and the tail waterflow state controller controls a blade angle beta 1 of cross-flow water turbine-generator set rotating wheel blades, a blade angle beta 2 of the gold spiral rotating wheel blades and moving distance x of a sensing driving rod. According to the intelligent water turbine system, a lot of kinetic energy in tail waterflow can be sufficiently utilized to generate electricity.

Description

technical field [0001] The invention belongs to the technical field of hydropower generation, and in particular relates to an intelligent water turbine system with a golden spiral 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 power s...

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
