The utility model discloses make the water form annular directional flow, simulate river course flowing water habitat, improved the mobility of water greatly, simultaneously higher oxygen transfer rate can be obtained, the dissolved oxygen in the water is improved, the production of dead water region has been avoided in the be convenient for exchange of water, be convenient for the cell body unloading and clean.
Description
Technical field
The utility model relates to parent population spawning inducing pool, particularly a kind of pulling flow type annular spawning inducing pool, is mainly applicable to hastening parturition of pipelining parent population in fish multiplication station.
Background technology
The parent population cultivated in fish multiplication station, power station is generally the rare protection fish in river course, is adapted to live in pipelining section.Current spawning inducing pool generally adopts circle or oval pond body, and pond body water surface area is less, is generally 5 ~ 10m
2, the general 1 ~ 1.5m of the depth of water, water inlet is positioned at Chi Ding, and delivery port is positioned at Chi Di center, and water body flow is poor, reoxygenation ability, is unfavorable for that pipelining parent population is hastened parturition.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pulling flow type annular spawning inducing pool, can simulating riverway flowing water habitat, improves water body flow, improves the dissolved oxygen in water body, be conducive to pipelining parent population and hasten parturition, be convenient to aquaculture management.
The technical scheme that the utility model technical solution problem adopts is: a kind of pulling flow type annular spawning inducing pool, comprise annular pool body, described annular pool body comprises the interior gallery of arranged concentric and outer gallery, the bottom of described annular pool body is provided with multiple flat water inlet, described multiple flat water inlet is arranged in the centre bottom described annular pool body end to end, make forming unidirectional liquid stream into during water, the top of described outer gallery is provided with multiple overfall, described spawning inducing pool also comprises water inlet pipe and outlet pipe, described water inlet pipe is communicated with described multiple flat water inlet, described multiple overfall is connected to described outlet pipe.
While employing technique scheme, the present invention can also adopt or combine and adopt following further technical scheme:
Described interior gallery and described outer gallery are track type annular gallery, described interior gallery comprises straight gallery and the arc gallery being connected straight gallery two ends in two in two that are parallel to each other, described outer gallery comprises be parallel to each other two outer straight gallerys and is connected the outer arcuate gallery at two directly gallery two ends outward, described arc gallery and described outer arcuate gallery concentric.
Described multiple flat water inlet is distributed on the bottom of described annular pool body, and the water inlet direction of described multiple flat water inlet is consistent, is all clockwise or counterclockwise, can forms unidirectional liquid stream when intaking in annular pool body.
The bottom of described annular pool body is provided with multiple uniform blow-down pipe, and described blow-down pipe and described flat water inlet interval are arranged.
The beneficial effects of the utility model are: the utility model adopts annular pool body, and arrange one group of water inlet at pond body bottom even, strong unidirectional liquid stream can be produced, plug-flow successful, each water inlet complements each other to form and is all clockwise direction or is all anticlockwise plug-flow, make water body form annular orientation flowing, simulating riverway flowing water habitat, substantially improves the mobility of water body; Higher OTR can be obtained simultaneously, thus improve the dissolved oxygen in water body; Outlet pipe and the relatively uniform layout of water inlet pipe, be convenient to the exchange of water body, thus avoid the generation of slough; The setting of blow-down pipe, is convenient to emptying and the cleaning of pond body.
Accompanying drawing explanation
