the fish method of crossing of a kind of water conservancy and hydropower dam of the present invention is, the method is that the bottom of river channel in the tailrace outlet downstream of power plant building lays underwater rail, replace existing fish gathering ship by the fish gathering platform be located on underwater rail, never having the section of navigation condition and fish gathering ship with solution cannot near the problem of tail water district, power plant building fish gathering difficulty.
in preceding method, the starting point of described underwater rail is as far as possible close to power plant building tailrace outlet; Underwater rail adopts double track structure to arrange along river course water (flow) direction, and double track spacing so that fish gathering platform corresponding with the wheelspan of fish gathering mesa base can under water track run arbitrarily.
in preceding method, described fish gathering platform is provided with fish detector, the situation that fish gathering platform is assembled according to the fish detector observation shoal of fish, the position of adjustment fish gathering platform under water on track, thus completes fish gathering process.
in preceding method, after described fish gathering dock door, be provided with anti-escape device, fish-baiting instrument successively, cross fish gallery and storage fish box; Fish enters fish gathering platform from entrance through anti-escape device under the luring of fish-baiting instrument, then passed through fish gallery enter storage fish box complete fish gathering process.
in preceding method, described fish-baiting instrument utilizes power station generating tail water to form attraction current and the shoal of fish is drawn into fish gathering platform.
according to the fish device excessively of of the present invention a kind of water conservancy and hydropower dam that said method is formed, this device comprises the underwater rail being located at bottom of river channel, and track is provided with fish gathering platform under water.
in aforementioned means, the starting point of described underwater rail is positioned at tailrace outlet district, power plant building and arranges along river course water (flow) direction.
in aforementioned means, described fish gathering platform is provided with fish detector.
in aforementioned means, after described fish gathering dock door, be provided with anti-escape device, fish-baiting instrument successively, cross fish gallery and storage fish box.
owing to have employed technique scheme; the present invention compared with prior art; the present invention by being equipped with pulley and track under fish gathering platform; make fish gathering platform can carry out fish gathering in tail water downstream certain limit; overcome the problem that fish gathering ship is difficult to carry out fish gathering near tail water; improve the validity of the fish gathering of fish collection system, for the contradiction coordinated between Hydraulic and Hydro-Power Engineering and ecological environmental protection serves positive effect.
