De-mechanized tubular fishway device

Abstract

The invention discloses a de-mechanized tubular fishway device. The de-mechanized tubular fishway device comprises a water storage mechanism for providing a stable water flow for transporting fishes,a fish collecting mechanism for gathering the fishes in a downstream reservoir, and a transportation mechanism for lifting and transporting the fishes in the fish collecting mechanism to an upstream reservoir; the water storage mechanism comprises a water storage tank with the stable water level and a first water feeding tube communicating with the water storage tank; the fish collecting mechanismcomprises a fish collecting tank used for gathering the fishes in the downstream reservoir, a second transportation tube communicating with the fish collecting tank, a fish collecting tube communicating with the first water feeding tube through a double-way valve, and a fish luring facility; and the transportation mechanism comprises a first transportation tube communicating with the second transportation tube and the fish collecting tube through a three-way valve, a water outlet of the first transportation tube corresponds to the upstream reservoir, and the elevation of the water outlet is larger than the water level in the water storage tank. A system operates through the inertia of water, then the fishes are transported into the upstream reservoir, a school of fishes is taken away at atime, thus the water consumption is greatly saved, and the water consumption efficiency of fish passing is improved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy projects, and relates to the design of fish passing facilities in water conservancy projects, in particular to a de-mechanized tubular fishway device. Background technique [0002] During the construction of water conservancy and hydropower projects, the complete river ecosystem is often divided, which blocks the return passage of fish, so the genes of fish under the dam and above the dam cannot be exchanged normally, and the vitality of species may decrease. The species distribution and habitat will also change, and these changes will lead to the deterioration of the ecological environment of the watershed and the fragmentation effect of the river ecosystem. Fish-passing facilities have been used internationally for more than 300 years as a fish protection measure to alleviate the barrier effect of dams, and can restore fish return channels and communicate upstream and downstream fish e...
