A tail self-yawing semi-rotary impeller turbine

Abstract

The invention discloses a tail wing self-yawing type half-rotating impeller water turbine, and belongs to the technical field of new energy. According to the water turbine, through gear transmission,the motion rule of the water turbine is kept as follows an output shaft rotates by a circle, water turbine blades rotate by half circle, the phase difference between two blades is 90 degrees, the topof an outer frame of the water turbine is connected with a bearing, the rear end of the outer frame is connected with a water drop type tail wing, along with changes of the water flow direction, force, acting on the tail wing, of the water flow generates yawing moment for the outer frame, the water turbine is driven to perform deflection, and can right face the water flow direction, and the influence of the water flow deflection on the efficiency of the water turbine is reduced. According to the tail wing self-yawing type half-rotating impeller water turbine, a tail wing self-yawing mechanismis adopted, the consumption of the electric amount of the small water turbine can be reduced, and the adaptation water area is wide.

Description

Technical field: [0001] The invention belongs to the technical field of new energy, and in particular relates to a self-yawing empennage semi-rotating water turbine. Background technique: [0002] Energy is an urgent problem that must be solved for the survival and development of human beings today. Strengthening the development of new green and non-polluting energy is an urgent need for human beings around the world. As one of the new green and non-polluting energy sources, ocean energy is a renewable and clean energy with abundant reserves. . A water turbine is a power machine that can convert the energy of water flow into rotating mechanical energy, so it can convert ocean energy into the electrical energy we need. However, for many current water turbines, in order to ensure efficient power generation when the water flow changes, usually The motor or hydraulically driven water turbine is used to align the incoming flow direction, which consumes a lot of power for the min...

A water turbine is a power machine that can convert the energy of water flow into rotating mechanical energy, so it can convert ocean energy into the electrical energy we need. However, for many current water turbines, in order to ensure efficient power generation when the water flow changes, usually The motor or hydraulically driven water turbine is used to align the incoming flow direction, which consumes a lot of power for the miniaturized water turbine. At the same time, sensors and other measurement systems are needed to detect changes in the water flow direction, and its operation reliability in water will be very difficult. ensure
