Description
Technical field
The present invention relates to high dam earial drainage dissolved gas supersaturation experimental provision, specifically a kind of water body saturation dissolved oxygen fish damage threshold value experimental provision.
Background technology
In the dam sluicing process, strong turbulent fluctuation takes place in following sluicing stream, forms the countless globules, and oxygen is significantly improved by the quantity that the aqueous vapor interface enters water body, thereby the content of dam downstream river course dissolved oxygen is obviously improved, will come adverse effect to aquatic biozone, downstream.
The supersaturation of water body dissolved oxygen causes that easily fish suffer from bubble illness, causes the enteron aisle of fish bubble to occur, or adheres to many minute bubbles on the body surface, the gill, makes fish body come-up or the disequilibrium of moving about, and can cause mortality when serious.This sick main harm fry, acute case can cause the lethality of fry 100%.But relevant water body saturation dissolved oxygen fish damage threshold value is also indeterminate now, only fish for by the field and obtain some immethodical data, and the consumption manpower and materials is huge, and whole utilization ratio is low.This threshold values plays crucial effects to relevant fish protection simultaneously.Research water body saturation dissolved oxygen fish damage threshold value is significant to understanding organic evolution and species conservation.
The patent No. is that 201120020517.9 Chinese utility model patent discloses a kind of " the multi-functional behaviouristics device of fish ", but it belongs to the Basic of Biology research field, can only be under the condition that satisfies fish swimming ability, researching fish can not be used for the experiment of water body saturation dissolved oxygen fish damage threshold value to intensity of illumination, illumination color, current preference etc.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of prior art, a kind of water body saturation dissolved oxygen fish damage threshold value experimental provision is provided, easy to use, can satisfy fish swimming ability, adapt to the fish of different size, and can realize the current self-loopa, save manpower and financial resources, improve whole utilization ratio.
The technical scheme that the present invention solves above technology technical problem is:
Water body saturation dissolved oxygen fish damage threshold value experimental provision comprises circulation variable frequency pump and circular airtight water tank, and the circulation variable frequency pump is communicated with circular airtight water tank by outlet pipe; Be separated at least two swimming lanes by detachable toroidal membrane along circular airtight water tank circumferencial direction in the circular airtight water tank, circular airtight water tank is provided with apopore in the middle of the bottom, be connected to the vertical outlet pipe of vertical direction on the apopore, apopore is communicated with supply tank by the water inlet pipe of the outer vertical water service pipe of the case of outlet pipe, vertical direction at the bottom of the case of vertical outlet pipe, horizontal direction and horizontal direction successively, and the outer vertical water service pipe of outlet pipe and case is connected to form the U-shaped tubular construction at the bottom of vertical outlet pipe, the case; Circular airtight water tank inwall is provided with annular conduit, and the water inlet of annular conduit is communicated with the outlet pipe of circulation variable frequency pump, and the delivery port of annular conduit is communicated with the outer vertical water service pipe of case by the outlet conduit that is provided with the outlet conduit valve; Annular conduit is along the equidistant delivery port that offers on the circular airtight water tank circumferencial direction, each delivery port is connected to one towards the water pipe that branches out at circular airtight water tank center, branch out water pipe towards the sealing of the end at circular airtight water tank center, branch out and spaced apartly on the tube wall of water pipe be provided with the transversely arranged aperture that is positioned at each swimming lane; The top edge of each detachable toroidal membrane is along the circumferential direction gone up and is equidistantly offered and branch out the sluicing estuary that matches the water pipe position, is covered with the water hole on the vertical outlet pipe; Also comprise air feeder and supply tank, air feeder is connected with supply tank by air supply pipe, and in order to charge into gas in supply tank, air supply pipe is provided with air-supplying valve, be provided with the electrochemical probe of measuring in order to saturation dissolved oxygen in the supply tank, supply tank is communicated with the circulation variable frequency pump by feed pipe.
Like this, power by the circulation variable frequency pump forms annular water flow in annular conduit, the big I of current is controlled by the valve that adjusting is connected the outlet conduit of annular conduit according to the fish size, the outer vertical water service pipe of outlet pipe and case is connected to form the U-shaped tubular construction at the bottom of vertical outlet pipe, the case, can control the depth of water of circular airtight water tank by the outer vertical water service pipe of case; The aperture effect that branches out water pipe is to make current in each swimming lane by the water in the release annular conduit.
The present invention and the patent No. are that 201120020517.9 " the multi-functional behaviouristics device of fish " difference is: increase aerating device: air feeder, supply tank, air-supplying valve, air supply pipe, electrochemical probe and feed pipe, (namely knowing under fish swimming required flow rate, the depth of water situation) under the condition that satisfies fish swimming ability, can carry out the water body saturation dissolved oxygen to the observation experiment of fish damage; The invention belongs to ecological hydro science field of environment protection, mainly cause that by the high dam earial drainage downstream river course dissolved gas supersaturation problem proposes; Relevant high dam earial drainage causes that the downstream river course dissolved gas supersaturation Study on Problems time is not long, so which kind of gas is caused not very unified final conclusion of gas diseases, begin most most scholar and think nitrogen, but now a lot of scholars think oxygen, so this experimental provision also can be changed the gas in the air feeder, it is replaced with one or more gas mixture bodies experimentizes, be which kind of dissolved gas causes gas diseases on earth to draw, thereby some environmental problems that cause for river construction provide the solution foundation; Relevant water body saturation dissolved oxygen fish damage threshold value is also indeterminate now, only fish for by the field and obtain some immethodical data, and the consumption manpower and materials are huge, and the present invention's chamber experiment by experiment determines variety classes and age of a fish water body saturation dissolved oxygen fish damage threshold value; Water tank of the present invention does not have light tight curtain, experiment not only can also can be observed by circular airtight water tank by computer observation, because this experiment has damage to the experiment fish, and want to observe more difficult in all directions by camera and the computer screen on top for the circular airtight water tank of an internal diameter 2m, so the laboratory technician can observe by computer on the one hand, directly observe by circular airtight water tank on the one hand, in case the sick pathological reaction of gassing can stop experiment, and will test fish and shift, the experiment fish can re-use after recovering like this, saves cost greatly; When realizing the water body circulation, guarantee that the dissolved oxygen in the circular airtight water tank maintains a certain stable dissolved oxygen concentration scope, because in the oversaturated phenomenon of actual dam earial drainage dissolved gas, its degree of saturation of place of more than 100 kilometer is still very high on the distance dam, four or five hundred kilometers place almost just can return to more normal state, and also needs to keep the stable state of saturation dissolved oxygen from the experiment principle.
