Birotor efficient forward loading water bucket type hydraulic generator

Abstract

The invention discloses a birotor efficient forward loading water bucket type hydraulic generator. The birotor efficient forward loading water bucket type hydraulic generator comprises a first rotor mechanism, a second rotor mechanism, a runner mechanism, a fixed spindle and a spray pipe. The runner mechanism comprises a water bucket and a turbine disc which is hollow. The water bucket is distributed on the outer circumference of the turbine disc. The outer circumference of the first rotor mechanism is fixedly installed on the inner circumference of the turbine disc. The second rotor mechanism and the first rotor mechanism are arranged coaxially in an inner-outer spaced mode. The center of the second rotor mechanism is fixedly installed on the fixed spindle. The spray pipe is installed on the outer side of the radial direction of the water bucket. According to the birotor efficient forward loading water bucket type hydraulic generator, a ventilating system or a cooling water system is not needed, few consumables are needed, the universality is good, the size is small, the material requirement is low, and the service life is long.

Description

technical field [0001] The invention relates to the field of hydropower equipment, in particular to a dual-rotor high-efficiency front-mounted water bucket type hydraulic generator. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotating mechanical energy, which is used to drive a generator to generate electricity. According to the working principle, water turbines can be divided into two categories: impact turbines and impact turbines. [0003] The runner of the impact turbine rotates under the impact of the water flow, and the pressure of the water flow remains unchanged during the working process, mainly due to the conversion of kinetic energy; [0004] The runner of the impact turbine is rotated by the reaction force of the water flow in the water, and the pressure energy and kinetic energy of the water flow are changed during the working process, but mainly the conversion of the pressure energy.

Problems solved by technology

[0008] However, the existing hydroelectric generators are all composed of separate hydro turbines and generators. The hydro turbines need to be connected to the generators through main shafts, rotating shafts and other components. The structure of the hydro turbines and generators requires at least three bearings. complex structure and expensive servomotor; and because the generator will generate a lot of waste heat during operation, it is necessary to design a ventilation or cooling system to dissipate heat from the generator; in addition, due to the existing generator stator, rotor, salient The required heat resistance is relatively high, and the material strength of the stator, rotor, and salient poles is high; in addition, the existing hydroelectric generator adopts a series connection structure of the water wheel, generator, and exciter, resulting in a huge volume and requiring materials Many, high cost and high cost
