Description
Technical field
the utility model relates to a kind of fish device excessively of water conservancy and hydropower dam, belongs to Hydraulic and Hydro-Power Engineering technical field.
Background technology
the construction of Hydraulic and Hydro-Power Engineering dam, has blocked fish population interchange, fish pass structure be recover aquatile exchange critical facility, to fish trace back lay eggs and population exchange have important effect.
fish pass structure mainly contains several forms such as fish pass, fish lock, fish lift and transporting something containerized fish system.Wherein, transporting something containerized fish system is arranged hinge major project not to be affected substantially, be applicable to project playout condition difficulty and built dam carries out reconstructing the engineerings such as fish pass structure, wherein the quality of fish collection system operational effect is whether whole transporting something containerized fish system is effective crucial.
at present, fish collection system principal mode is fish gathering ship, and fish gathering ship has following weak point, as: Hydraulic and Hydro-Power Engineering dam generally only lets out ecological flow down, and downstream flow is less, and water is shallow, river surface is narrow, and riverbed is main mainly with stone riprap, and boat for collection and transportation of fish often can not safe operation; The place that the shoal of fish the most easily assembles in the main flow certain limit of tail water downstream, and it is more obvious the closer to power plant building tailrace outlet fish-gathering effect, but because factory building generating flow is unstable, consider safety problem, fish gathering ship can not carry out fish gathering near Daba Power Plant room tailrace outlet.
Utility model content
the purpose of this utility model is, what provide a kind of water conservancy and hydropower dam crosses fish device, and never having the section of navigation condition and factory building tail water district with solution can not the problem of fish gathering, thus overcomes the deficiencies in the prior art.
the technical solution of the utility model is achieved in that
the fish device excessively of a kind of water conservancy and hydropower dam of the present utility model is that 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 utility model compared with prior art; the utility model 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.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-river course, 2-underwater rail, 3-fish gathering platform, 4-power plant building tailrace outlet, 5-fish detector, 6-anti-escape device, 7-crosses fish gallery, 8-fish-baiting instrument, and 9-stores up fish box.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model is constructed by the mistake fish method of following a kind of water conservancy and hydropower dam, as shown in Figure 1, 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.The starting point of 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.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.Be provided with anti-escape device, fish-baiting instrument after fish gathering dock door 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.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 utility model a kind of water conservancy and hydropower dam that said method is formed, as shown in Figure 1, this device comprises the underwater rail 2 be located at bottom river course 1, and underwater rail 2 is provided with fish gathering platform 3.The starting point of underwater rail 2 is positioned at power plant building tailrace outlet 4 district and arranges along river course 1 water (flow) direction.Fish gathering platform 3 is provided with fish detector 5.Be provided with anti-escape device 6, fish-baiting instrument 7 after fish gathering dock door successively, cross fish gallery 8 and storage fish box 9.
Embodiment
this comprises the fish gathering platform 3 that fish-baiting instrument 7 and pulley are housed and the underwater rail 2 be laid on bottom river course 1 such as shown in Fig. 1.Fish gathering platform 3 assembles situation according to fish detector 5 detecting fish school, carries out fish gathering in power plant building tailrace outlet 4 district and along the underwater rail 2 of river course 1 water (flow) direction laying slides.The starting point of underwater rail 2 is arranged in tail water district, power plant building along river course, and as far as possible near power plant building tailrace outlet 4, track is arranged under water along river course.Fish gathering platform is made up of corresponding detecting devices and pulleys etc. such as fish-baiting instrument, anti-escape devices, excessively fish gallery.Fish gathering platform can slide along track, is made up of the fish gathering platform 3 and underwater rail 2 that fish detector 5 and pulley are housed.The starting point of track is arranged in factory building generating tail water side along river course 1, and as far as possible near factory building tail water, track is arranged under water along river course 1, and gauge matches with the width of fish gathering platform 3.Fish gathering platform is primarily of fish-baiting instrument 7, excessively fish gallery 8 and corresponding detecting devices composition.Fish-baiting instrument mainly utilizes power station generating tail water to form attraction current.Anti-bell-mouthed anti-escape device 6 is set after import.Cross fish gallery 8 and be positioned at import back segment.Storage fish box 9 was positioned at the rear end of fish gallery 8.Fish gathering platform 3 has pulley, pulley and track supporting.Fish gathering platform 3 can according to the result of detection of fish detector 5, mobile position in orbit.
