Ship lock combined with vertical crack type fishway and using method thereof

Abstract

The invention discloses a ship lock combined with a vertical crack type fishway and a using method thereof. The ship lock comprises an upstream navigation wall, a head bay, a lock chamber, a lock chamber wall body, a tail bay and a downstream navigation wall which are sequentially arranged, wherein an upstream 1 # gate and an upstream 2 # gate are arranged at the head bay, and a downstream gate isarranged at the tail bay; and a plurality of flow guide plates and a plurality of partition plates are arranged in the lock chamber wall body, the partition plates and the flow guide plates are connected with the lock chamber wall body through rotating shafts correspondingly, and the partition plates and the flow guide plates are in one-to-one correspondence to form a plurality of pool chambers.According to the ship lock, the partition plates, the flow guide plates and an additional device are arranged in the ship lock to realize fish passing, the vertical crack type fishway is built in thelock chamber of the ship lock, so that the fishway and the ship lock are combined into one, and the investment cost is saved; and the structure of the ship lock is simple in arrangement, and convenient to manage.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a ship lock combined with a vertical slot fishway and an application method thereof. Background technique [0002] In order to meet the needs of flood control, irrigation, power generation, etc., it is necessary to build river barrages on natural rivers. The completed river barrages will not only exert engineering benefits, but also cause damage to the ecosystem in the river basin. The operation of the barrage structures destroyed the original ecological continuous water system of the river, turning the river into a series of continuous distributed but separated static water ecosystems; The water temperature, flow velocity and oxygen content show obvious vertical stratification phenomenon, which affects the species structure and habitat environment of the original river ecosystem; at the same time, the barrage structures block the migration chann...

AI Technical Summary

Problems solved by technology

The operation of the barrage structures destroyed the original ecological continuous water system of the river, turning the river into a series of continuous distributed but separated static water ecosystems; The water temperature, flow velocity and oxygen content show obvious vertical stratification phenomenon, which affects the species structure and habitat environment of the original river ecosystem; at the same time, the barrage structures block the migration channel of migratory fish. As a result, the migration rate and reproduction rate of migratory fish in the river basin will decrease, which will lead to a continuous decline in the number of fish in the river basin, affecting the ecological diversity of water and destroying the river ecosystem.
