Description
Technical Field
The invention relates to the field of hydraulic and hydroelectric engineering and ecological environmental protection engineering, in particular to an induced driving integrated dam fish passing device and a use method thereof.
Background
Due to various engineering requirements such as power generation, irrigation, landscape, water conservancy and the like, people often build water retaining structures such as dams and the like in water systems such as riverways, and the water retaining structures often obstruct or block the migration of aquatic organisms such as migratory fishes and the like in the riverways and directly or indirectly damage or even destroy the aquatic organisms in the water systems such as the original riverways and the like. With the continuous improvement of development degree of water energy and water resources in China, more and more various water retaining buildings such as barrages and the like are built on main streams and branch streams of riverways. Although people still research and pay attention to the problems of migration, inhabitation, propagation and the like of aquatic organisms such as migratory fishes before the barrage is built, a fishway and an ecological flow discharge device are built in hydropower stations with few conditions, and fish proliferation stations are specially built in some hydropower stations. However, for various reasons, engineering efficacy of ensuring migration, inhabitation and propagation of fishes is not satisfactory. For example, in a certain hydropower station built in east China in the 70's of the last century, although a fishway is built between a dam spillway and a power generation plant, migratory fishes attempt to swim to an upstream reservoir of a dam from a downstream river of the dam to a downstream river of the dam in an upstream manner by going through an artificial fishway in a reverse flow, the actual effect is not ideal, and the hydropower station is nearly abandoned due to no fish.
With the enhancement of national environmental awareness, hydropower stations with built fish systems are increased continuously, but the fish systems with fish passing efficacy are almost not available, so that methods and means such as building fish elevators, fish breeding stations, adopting artificial fishing and then vehicle transportation have to be developed, and the obstruction and damage to aquatic organisms such as migratory fish are reduced. Unfortunately, the above methods and means are often undesirable, either with limited effectiveness or at high operating costs. The migratory fish's countercurrent migration habit is formed during the lengthy evolution process. At present, the artificial fishway fish passing mode generally adopted in engineering caters to partial migratory fishes through partial parameters such as water flow velocity, flow and the like, but the engineering scale is large, the construction cost and the operation and maintenance cost are high, and the fish passing effect cannot reach an ideal state. A traditional dam fish passing system generally adopts a self-flowing type artificial fishway, and the fishway is complex in structure, large in occupied area, high in construction cost and large in limitation. Particularly, for dams with the difference between upstream water level and downstream water level exceeding 50 meters, the traditional self-flowing fishway is difficult to realize, even if the dam is reluctant to realize, the construction scale and the engineering investment are considerable, and the more fatal defect is that the fish passing effect is often poor. Other fish-crossing damming and injury similar to manual arrest of a fish in a reverse transport are also conceivable.
