Description
Technical field
The present invention relates to a kind of experimental technique and device, particularly relate to and a kind ofly simulate the experimental facilities that fish crossed by ship lock.
Background technology
Fish pass structure is the engineering measure being communicated with fish migration or migration, mainly comprises fish pass, fishway, fish lift and fish gathering ship etc.But China's major part fish pass operating condition is unsatisfactory, and reason mainly comprises: lack understanding fully to various fish life habit and behaviouristics, cause fish pass entrance location to arrange improper, flow-shape in fish pass, flow velocity are improper; Generally during fish pass design only to carry out for other Fish of interest individual, by fingerling and limited amount; The descending problem of fish pass is studied still few at present, does not propose effective measures and solves; Simultaneously in key water control project design, Construction and management, generally yet there is fish pass and take up an area comparatively large, difficult arrangement, build cost higher, run the problems such as water consumption is large, complex management.
Ship lock is for dam crossed by ship and build, and is building required when building key water control project on great rivers.The water stream channel of the large above and below the dam of ship lock Ye Shi UNICOM, has larger UNICOM's water body, ought to become the habitat of some biology of river and the biological corridor of UNICOM's upstream and downstream.Research data shows: ship lock allows having free passage of large above and below the dam fish to a certain extent, has certain opposing traffic potentiality.Therefore, improved by ship lock or increase after some lure and drive fish measure, utilizing ship lock to cross fish can realize.
But, in the ship lock of actual motion, because ship lock size is comparatively large, structure is more complicated, have the reasons such as navigation requires, water level is darker, be not easy to lure and drive fish experiment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly simulates the experimental facilities that fish crossed by ship lock, the improvement fish pass of pipeline bath and light source attracting is utilized to cross methods experiment method and the device of fish effect, can overcome the existing deficiency crossing fish technology, construction is laid simple, and construction cost is low.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind ofly simulate the experimental technique that fish crossed by ship lock, reasonable Arrangement pipe-line system on the lock wall of ship lock, washed by water in downstream, by speed and the angle of injection of the bath of adjustment pipeline, change flow velocity and the fluidised form in ship lock downstream, what make it reach Fish of interest likes flow velocity, thus attract fish to enter the lock chamber of ship lock, then enter upstream.
In the lock chamber of ship lock, arrange multiple bulb, manufacture light source and carry out attracting, play the effect strengthening attracting.
Pipe-line system is the flushing pipeline of the multi-ribbon adjustable-angle nozzle that ladder is arranged on Retaining Wall of Shiplock, or the flushing pipeline of the multi-ribbon adjustable-angle nozzle be arranged in juxtaposition on Retaining Wall of Shiplock.
A kind ofly simulate the experimental facilities that fish crossed by ship lock, comprise tank, flushing pipeline and the tank of water tank, water pump, speed governing valve, distributive pipe, many band adjustable-angle nozzles are contacted by pvc pipe, form the circulating system that provides certain speed current, automatic control water level gate is installed in tank, be vertically arranged with dam body and ship lock in tank, the flushing pipeline of many band adjustable-angle nozzles is arranged in the lock chamber of the ship lock of tank.
In the lock chamber of ship lock, multiple fish-luring light is also installed.
Many flushing pipelines ladder on the lock wall of ship lock is arranged or is arranged in juxtaposition.
Provided by the inventionly a kind ofly simulate the experimental facilities that fish crossed by ship lock, the improvement fish pass of pipeline bath and light source attracting is utilized to cross fish effect, take into full account the ecological habit of fish, ensure that fish has good compliance to ship lock, the existing deficiency crossing fish technology can be overcome, construction is laid simple, and construction cost is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the structural representation of apparatus of the present invention;
Fig. 2 is the top view of apparatus of the present invention.
Detailed description of the invention
