Longitudinal sinking compression type axial flow multi-blade propeller power generation device

Abstract

The invention provides a longitudinal sinking compression type axial flow multi-blade propeller power generation device, and relates to the technical field of power generation devices. The longitudinal sinking compression type axial flow multi-blade propeller power generation device comprises a flexible flow guide channel which is arranged in a river channel and is arranged in a gradual shrinking mode in the flowing direction of river water, and a power generator set is arranged at the compression outlet end of the flexible flow guide channel. According to the longitudinal sinking compression type axial flow multi-blade propeller power generation device, the problems that in the prior art, a dam is complex in construction, high in cost, large in influence on the river channel and the surrounding ecological environment and prone to damaging the ecology, and when the flow speed of the river water is low, rotating blades cannot be driven to rotate, power generation output is prone to being interrupted, and the power generation amount is low are solved.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a longitudinally sinking compression type axial flow multi-blade paddle power generation device. Background technique [0002] Hydropower generation uses rivers, lakes, etc. to flow water with potential energy from high places to low places, convert the potential energy contained in it into kinetic energy of water turbines, and then use water turbines as the driving force to drive generators to generate electricity. Use hydraulic power (with water head) to drive hydraulic machinery (water turbine) to rotate, and convert water energy into mechanical energy. If another type of machinery (generator) is connected to the water turbine to generate electricity with the rotation of the water turbine, then the mechanical energy is transformed. for electrical energy. In a sense, hydropower is a process in which the potential energy of water is converted into mechanical en...

Problems solved by technology

[0009] Aiming at the deficiencies in the prior art, the present invention provides a longitudinal sinking compression type axial-flow multi-bladed paddle power generation device, which is used to solve the cumbersome construction of the dam in the traditional technology, the high cost, and the impact on the river course and the surrounding ecological environment. Large, easy to damage the ecology; when the river flow rate is low, it is impossible to drive the rotating blades to rotate, and the output of power generation is prone to intermittent and low power generation
