Description
Technical Field
The utility model relates to the technical field of construction of inland ship locks and avionic locks, in particular to an ecological fishway structure of an inland ship lock.
Background
In recent years, large-scale dam construction is performed on rivers to raise the water storage level, and the dam is used for flood control, water supply, irrigation, hydroelectric power generation, shipping improvement and the like. However, after the gate dam cuts off the river channel, the natural river channel of the fish is blocked, and the influence on the life cycle, the inhabitation space, the life habit and the like of the fish is caused, so that the fish passing channel is required to be arranged, and the migration of the fish is satisfied. Fishways can be divided into two types of pool-type fishways and groove-type fishways according to structural forms. The pool type fishway is composed of a pool connected with the upstream and the downstream in series and is very close to a natural river, but the pool type fishway is small in applicable water head and large in occupied area, so that the applicability is limited. The channel fishway is divided into a simple channel type fishway and a diaphragm type fishway, the diaphragm type fishway divides the total water level difference of the upstream and downstream of the water channel into a plurality of cascade pond chambers, namely cascade fishway or fish ladder, the fishway dissipates energy by utilizing water cushion, along-path friction and water flow opposite flushing and diffusion, improves the flow state, reduces the flow velocity of fish passing holes, and can adapt to the requirements of fishes with different habits by adjusting the form, the position and the size of the fish passing holes.
In the field of construction of inland ship locks and navigation armature buttons, structures and facilities are arranged beside a dam body or a dam independently for fish to pass through barriers such as the dam and the water lock, so that the construction method is large in occupied area and high in construction difficulty, and meanwhile project construction cost is increased. In recent years, there is no case of using ship locks as fishways, such as the chinese patents CN 202010417336.3 and CN202010024741.9. However, the ship lock is designed for controlling water flow initially so that ships can pass through, and the fishway needs to provide a proper water flow environment so that fish can migrate smoothly, and the water flow speed and water level control of the ship lock can cause trouble to the migration of fish so as to influence the survival and reproduction of the fish; ship locks are often of large size and complex construction, where there may be factors unsafe for fish, such as turbulence in the water flow, operation of mechanical equipment, etc., which may cause injury to the fish or prevent their passage; the ship lock is generally used for manually regulating the water area flow, and the migration of fishes is generally dependent on natural water flow conditions, and the ship lock is used as a fishway, so that the fishes can encounter difficulty in adapting to and by means of the artificial environment, and the migration is failed or stopped; the ship lock and the fishway have different requirements in terms of design, construction, maintenance, management and the like, and combining the two may increase management difficulty and cost, and requirements on related technologies and resources.
