Dam-free linked hydroelectric power station with multiple conduits converging flow

Abstract

The invention belongs to the technical field of hydroelectric generation, and particularly relates to a dam-free linked hydroelectric power station with multiple conduits converging flow. The dam-free linked hydroelectric power station with the multiple conduits converging the flow is high in adaptability, low in investment cost, convenient to build, short in construction time and high in feasibility. The dam-free linked hydroelectric power station comprises the multiple power-generation water conduits (1), the flood discharging water conduits (2), a drop gate (3) and power generators (4). The power-generation water conduits (1) are all arranged in a river, the power generators (4) are connected to the power-generation water conduits (1) in series, and the flood discharging water conduits (2) are mounted above the power-generation water conduits (1). The drop gate (3) is located at water inlets of the power-generation water conduits (1) and water inlets of the flood discharging water conduits (2), the area of the drop gate (3) is at least equal to the cross sectional area of the stacked power-generation water conduits (1), and the drop gate (3) is moved up and down through a power device.

Description

technical field [0001] The invention belongs to the technical field of hydroelectric power generation, in particular to a multi-pipe concentrating flow without dam chain hydroelectric power station. Background technique [0002] The areas with the richest hydropower resources in my country and even in the world are often concentrated in alpine and valley areas. Due to the high altitude, severe cold and hypoxia, high mountains and steep slopes, broken geology, and changeable climate in these areas, natural disasters such as landslides and mudslides caused by factors such as rainfall and earthquakes occur frequently. Especially in watersheds with particularly rich water resources, the characteristics of mountains and valleys are more prominent, and road construction and maintenance are very difficult, and it is even impossible to build roads or ensure smooth roads. Therefore, it is more difficult to develop and utilize hydropower to generate electricity in places with abundan...

Problems solved by technology

[0003] Although hydropower is my country's current second source of electricity, compared with petrochemical energy, the proportion is still very low, less than 10%

[0009] This kind of design requires many conditions. First of all, it needs to pass through the Kaishan Tunnel, which has high requirements for the mountain conditions, surrounding environment and soil conditions. The engineers who lay subways and railways know that laying tunnels has certain requirements for soil conditions and mountain structures. Moreover, the construction volume is large, the construction time is long, and long-term maintenance is required. Otherwise, there is a danger of landslides. Secondly, the geographical environment required by the design requires not only mountains, rivers, but also sufficient multi-level diversion power stations through the diversion power station with more than two levels. construction space, it can be seen that the feasibility of this technical solution is not high
