Problems solved by technology

In fact, there is a large energy loss during these energy conversions
For example, the energy conversion loss caused by the hydroelectric generator itself
In addition, due to the characteristics of the fluid, the rapidly discharged water will drive the fluid velocity. This driving effect is based on the tension of the water flow, or the stress of the gravity of the discharged water can be traced back to the upper part of the water body, such as forming a vortex at the outlet of the reservoir, or A confluence is formed on the upper surface of the water, which carries a large amount of kinetic energy. Generally, the water turbine is installed at the bottom of the dam, and only uses the kinetic energy carried by the discharged water at the impeller section of the water turbine. However, the above-mentioned kinetic energy of the upper part of the water body caused by the tension of the discharged fluid cannot be utilized. , resulting in a large waste of
Chinese Patent 89102035.7 Recoil and Impulse Combined Turbine Utilizes "Recoil Action Loss" Existing in Impulse Turbines
The structure is more complicated, it is not easy to realize, and the reverse action is only a component of the discharge water flow, which does not necessarily increase the energy conversion efficiency

Embodiment 1

[0009] Embodiment 1: The downward-sloping drain pipe 3 is fixed on the dam 6, the water turbine unit 1 is fixed at the upper end of the drain pipe 3, the water inlet 2 is fixed at the front, and the water turbine unit 5 is fixed at the lower water outlet 4 at the lower end of the drain pipe 3.

[0010] Working principle: The dam 6 lifts the upper surface of the water body to a certain height to generate a certain potential energy. After the upper water inlet 2 is initially opened, the static water flow enters the drain pipe 3 from the upper water inlet 2, and flows downward along the drain pipe 3 under the action of gravity, reaching the lower water inlet 2. When the water outlet is 4, the water flow has a relatively high speed, and the potential energy of the water body is gradually converted into kinetic energy, and enters the lower water turbine unit 5, and the impact pushes the impeller of the lower water turbine unit 5 to rotate to do work, and converts the kinetic energy o...

Embodiment 2

[0013] Embodiment 2: The downward-sloping discharge pipe 3 is fixed on the dam 6, the upper end of the discharge pipe 3 is fixed at a distance from the front of the water inlet 2, and two sets of upper water turbine units 1 are fixed, and the water diversion is fixed in the dam 6 next to the upper water inlet 2 Mouth 7, water diversion nozzle 7 front ends are sharper, and two groups of upper water turbines 1 are distributed in water diversion nozzle 7 both sides, and the lower water outlet 4 rear portion of water discharge pipe 3 lower ends is fixed lower water turbine unit 5.

[0014] The upper water turbine unit 1 fixed in the fan-shaped angle area formed by the water diversion nozzle 7 and the upper water inlet 2 generates electricity under the action of the confluence of the upper water inlet 2; Part of the confluence at the water inlet 2 is diverted through the water diversion nozzle 7 to form a circular flow. Under the continuous movement of the confluence, the circular f...

Abstract

Disclosed is a power generation technology by using the flow stress of drained water, relating to a power generating technology that utilizes the effect of quickened flow speed generated due to the fluid tension at the top of falling water which is caused by falling water flow. A downward sloping drain pipe 3 is fixed on a dam 6 and an upper water turbine set 1 is fixed in front of an upper water inlet 2 at the upper end of the drain pipe 3 while a lower water turbine set 5 is fixed at the back of a lower water outlet at the lower end of the drain pipe 3. By using the tension and stress effects of the water flow, a water turbine set is additionally arranged at the upper inlet of the dam drain pipe based on the existing hydroelectric power generation technology without affecting the operation of the water turbine set, thus further fully improving the hydroelectric generating efficiency and reducing the impact damage to the dam structure due to the conflux at the upper water inlet. The power generation technology of the invention has a simple structure and is easy to be implemented.
