Transfer device between fishway and fish transport vehicle and its implementation method

Abstract

The invention relates to and aims to provide a transferring device between a fishway and a fish van and an implementation method thereof. The invention has the technical scheme that the transferring device consists of a fish collection device and a transshipment device, wherein the fish collection device comprises a fish collection channel; two sides of the fish collection channel, which are near an outlet end, are respectively provided with a first water supply pipe; the exit of the fish collection channel is provided with a waterstop valve and a fish screen; two side walls of the fish collection channel are both provided with sliding rails arranged along the length direction of the fish collection channel; the two sliding rails are used for jointly supporting a fish herding screen by a driving mechanism; one side wall of the fish collection channel is inwards concave; the inwards-concave position is provided with observation equipment; the observation equipment is connected with a computer; the transshipment device comprises a fishlock, wherein a transshipment funnel is erected on the fishlock; the top end of the transshipment funnel on one side of the fishlock is connected with the exit of the fish collection channel; the top end of the transshipment funnel on the other side of the fishlock is connected with a second water supply pipe with a water supply valve; the hole of the transshipment funnel is provided with a fish discharging valve; the bottom of the funnel just faces to a vehicle access road through which the fish van passes.

Description

technical field

[0001] The invention relates to a transfer device between a fishway and a fish transport vehicle and an implementation method thereof, which is a device for realizing automatic transfer of fish after being lifted from the fishway. The utility model is suitable for the field of water conservancy and hydropower aquatic ecological protection, and particularly relates to the structure of a fish passing facility. Background technique

[0002] The construction of the dam has artificially blocked the aquatic habitats that are freely connected between the upstream and downstream of the river, affecting normal life processes such as fish migration and population exchange. The fish passing facility is an important facility to communicate and block the river section and restore the exchange of aquatic organisms. It is especially important for the upward tracing of fish and the exchange of populations.

[0003] At present, fish passing facilities mainly include several ...
