Water diversion flow guide body of hydro-generator

Abstract

A water diversion flow guide body of a hydro-generator comprises a water diversion flow guide groove and a water diversion flow guide box arranged above the rear portion of the water diversion flow guide groove. The water diversion flow guide groove comprises two groove body side baffles (1a), a bottom plate (1b) and a rear arc flow guide baffle (1f) which form a groove body, and the rear arc flow guide baffle (1f) is used for guiding water flow to a water bucket below a water cart and gradually lowered. The water diversion flow guide box comprises two upper side baffles (1c) located at the top ends of the groove body side baffles and a flow baffle (1d) connected between the front ends of the two upper side baffles. An upper L-shaped back pressure prevention waterstop flow baffle (1e) with the two sides connected with the upper side baffles is arranged in the water diversion flow guide box, and the inner corner of the upper L-shaped back pressure prevention waterstop flow baffle (1e) faces the water cart. According to the water diversion flow guide body, water energy can be efficiently utilized, the power generation capacity of the water cart type hydro-generator can be greatly improved, and the manufacturing cost and maintenance cost of the water cart can be reduced.

Description

technical field [0001] The invention belongs to the technical field of waterwheel type hydroelectric generators. Background technique [0002] The existing various types of waterwheel-type hydroelectric generators are mainly divided into three categories. The first type is to place the waterwheel directly in the canal and use the impact force of the water flow to generate electricity. This waterwheel power generation method belongs to the most primitive waterwheel. The way of using the car mainly relies on the speed of the water flow to impact the rotation of the water wheel to drive the generator to generate electricity. Because only the impact kinetic energy of the water flow is used, the utilization rate of the potential energy of the water flow is very low, and the power generation efficiency is very low. The second type is to make the waterwheel into a bucket-type waterwheel. The water flow is poured into the bucket from the upper side of the waterwheel, and the gravit...

Problems solved by technology

However, this type of waterwheel-shaped direct wash-down turbine can only use the water head equal to or lower than the central shaft of the waterwheel. Once the water head is higher than the central shaft of the waterwheel, the pressure generated by the water flow higher than the central shaft of the waterwheel will form. The water entry resistance of the blades of the waterwheel produces reverse torque, so the water head that can be effectively used is at most the lower half of the height of the waterwheel. In order to increase the power generation capacity by using the water head, the waterwheel must be made larger, which will increase Difficulty and cost of manufacturing, transporting, installing and maintaining waterwheels
