Problems solved by technology

[0004] Existing hydroelectric power stations mostly build high dams, create large water level differences, require large investment, slow results, damage the environment, destroy trees, hinder fish migration and reproduction, and lead to unfavorable factors such as species extinction
There are still several major disadvantages of dam-building power stations: 1. Unstable power generation, more power generation in wet years and wet seasons, less power generation in dry years and dry seasons, more power generation at high water levels, less power generation at low water levels, and sometimes no power generation; 2. The utilization rate of water is low. The water in a reservoir can only be used once, and it flows downstream after power generation; 3. The precious river is flooded, and the loss is huge
Especially for river sections that are not suitable for building dams, it is difficult to use their energy

Embodiment Construction

[0013] The present invention increases the benefits of water flow power generation and accelerates the improvement of energy structure from two aspects.

[0014] One: if figure 1 As shown, the key factor for the operation of the channel with variable slope and the power generation capacity of the water flow power station is the flow velocity of the water flow, and the determinant factors of the flow velocity are the longitudinal slope of the channel and the smoothness of the channel surface. The greater the slope and the smoother the surface, the greater the velocity of the flow and the more power is generated. For example, for a channel with a vertical slope of 1300, usually the flow rate of its power generation can only be designed according to the vertical slope of 1300. The operation of the channel with variable slope of the present invention is just different, and its generating current velocity can be designed according to the vertical slope of 1%, and the flow velocity...

Abstract

The invention discloses a channel slope-changing power generation method. According to the method, a plurality of power generation stations are built on a channel; the channel between every two power generation stations is divided into two segments, namely a water delivery segment (1a) and a power generation segment (1b); the slope of the channel longitudinal slope of the water delivery segment (1a) is gentle and is called a gentle slope segment, the slope of the longitudinal slope is one thousandth or less than one thousandth; the surface of the channel is a rough surface or a smooth surface; the longitudinal slope of the channel of the power generation segment (1b) is steep; the surface of the channel is a smooth surface; an inverted siphon-type energy machine (1c)is arranged at the tail part of the power generation segment (1b) of the channel. According to the channel slope-changing power generation method, water flow is accelerated so that the surface water of the channel is changed into deep water flow by adopting channel slope-changing operation and the inverted siphon-type energy machine, so that the unit weight of the water flow is increased, and the power generation benefits are increased; therefore, the power generating capacity of a power generation station on a one three-hundredths channel singly is increased by 1.5 times.

Description

Technical field: [0001] The invention relates to a power generation method, in particular to a channel-slope-changing power generation method. Background technique: [0002] From winter to spring, rampant smog has harassed vast areas of my country's northeast, north, east, and central China, and some areas have been hit many times for a long time. High-speed road closures and flight suspensions have directly affected the health of the people. People hate it. Premier Li Keqiang declared war on smog in his government work report. It shows the central leadership's concern for the people and determination to control the smog. But this war will be a protracted one. It is impossible to achieve complete victory by 2050. Our country is a big country among developing countries. Over the past 100 years of imperialist aggression, we are backward and poor in all aspects. Only in the past 30 years has the reform and opening up been implemented, and the economy has developed by leap...
