Problems solved by technology

[0002] At present, water turbines for hydroelectric power generation mostly use water bucket type, jet flow type or worm gear type. These water turbines use the momentum of water to do work, so they require a large amount of water to operate. Usually, a dam needs to be built on site, which requires a high investment and resources. The use efficiency is low, so that the development of my country's electric power cannot meet and adapt to the pace of modern development

Embodiment 1

[0019] Combined with the attached drawings:

[0020] There is a hemispherical or cylindrical fixed wheel 3 and a moving wheel 4, the fixed wheel is fixed on the fixed seat 1, the inner wheel surface of the fixed wheel is coaxially sleeved with the outer wheel surface of the moving wheel, and there are holes on the inner wall of the fixed wheel and the outer wall of the moving wheel The V-shaped spiral water flow groove 5 in the opposite direction, the spiral water flow groove 5-1 on the fixed wheel 3 spirals upwards along the inner surface of the ball from the center ring at the bottom of the wheel, and the spiral water flow groove 5-2 on the moving wheel is formed by the shaft center of the bottom of the wheel. Spiral up along the outer surface of the ball. The rotating shaft 7 of the moving wheel is connected with the rotating shaft 10 of the generator, the bottom center of the fixed wheel is provided with a water inlet 9 communicating with the pressure water pipe 2, the upp...

Embodiment 2

[0023] The shape of the fixed wheel and the moving wheel of the water turbine in this embodiment is cylindrical, and there are V-shaped spiral water flow grooves in opposite directions on the inner cylindrical surface of the fixed wheel and the surface of the round bottom, and the outer cylindrical surface of the moving wheel and the surface of the round bottom. V-shaped spiral water flow grooves in opposite directions. The inner cylindrical wall of the fixed wheel and the outer cylindrical wall of the moving wheel are provided with V-shaped spiral water flow lines connecting the bottom of the circle from bottom to top.

Abstract

There is disclosed a pressure water-cushion type twin-screw water turbine, in which are disposed semicircular or cylindrical fixed and driving wheels is fixed on the fixed seat and the internal wheelface of the fixed wheel is in a coaxial interlink with the external wheel face of the driving wheel. The rotation shaft of the driving wheel is connected with the rotation shaft of generator. In the centre of the fixed wheel bottom is disposed a water inlet in communication with a pressure water pipeline. In the upper part of the fixed wheel is disposed an overflow groove and in the lower part ofthe overflow groove is disposed a return pipeline discharging the overflow water into a water-storage pool. By the action of the pressure waterflow of the inventive water turbine, the driving wheel can realize a counterrotation to drive the rotary generating of the generator.

Description

technical field [0001] The invention relates to a pressure water cushion type double-screw water turbine used for hydropower generation. Background technique [0002] At present, water turbines for hydroelectric power generation mostly use water bucket type, jet flow type or worm gear type. These water turbines use the momentum of water to do work, so they require a large amount of water to operate. Usually, a dam needs to be built on site, which requires a high investment and resources. Utilization efficiency is low, so that the development of my country's electric power cannot meet and adapt to the pace of modern development. " Contents of the invention [0003] The object of the present invention is to provide a pressure water cushion type double-shaft spiral water turbine with low investment and high resource utilization efficiency. [0004] The technical scheme of the present invention is: a hemispherical or cylindrical fixed wheel and a moving wheel are provided, th...
