Abstract
The utility model discloses a fish hatching ring channel which comprises a pool body, a boss arranged in the center of the pool body and a filter screen connected above the boss. The side wall of the boss tilts toward the center of the boss from bottom to top, the ring channel is formed between the pool body and the boss, the cross section of the ring channel in the vertical direction is of a U shape, spray nozzles which are evenly distributed along the ring channel are arranged inside the ring channel, and a water draining opening is arranged in the pool body. The technical scheme is used, according to the fish hatching ring channel, the side wall of the boss is arranged obliquely, the ring channel is deepened, water flow dead angles do not exist in the ring channel, under the condition that the pressure of water spraying of the spray nozzles is not changed, the water flow speed inside the ring channel can be accelerated, and the problems that roes stay in one dead space position and do not move along with the water flow are solved.
Description
Technical field
the utility model relates to a kind of fish hatching circuit.
Background technology
circular hatching channal is large-scale incubator, is applicable to the large-scale production needs, also can be built into medium and small circuit, adapts to medium and small production and application, and circuit has ellipse, square and circular.Circular hatching channal is connected with spawning inducing pool by pipeline, circular hatching channal comprises the pond body, is arranged on the boss of pool center, form circuit between pond body and boss, the circuit bottom is provided with along the equally distributed water inlet shower nozzle of circuit, by the bath of water inlet shower nozzle, makes the water drive fish-egg in circuit not arrhea moving.The sidewall of the boss in circular hatching channal of the prior art and pond body is vertically to arrange, and has the current dead angle in circuit, can cause fish-egg not move with current being stuck in place, a certain dead angle.
Summary of the invention
for overcoming above-mentioned shortcoming, the purpose of this utility model is to provide a kind of fish hatching circuit.
in order to reach above purpose, the technical solution adopted in the utility model is: a kind of fish hatching circuit, it comprises the pond body, be arranged on the boss of pool center, be connected to the filter screen of boss top, the sidewall of boss is centroclinal to boss from the bottom to top, form circuit between pond body and boss, the cross section of this circuit in the vertical direction is U-shaped, is provided with the shower nozzle of evenly arranging along circuit in circuit, on the body of pond, is provided with discharge outlet.
further, the height of boss is 40%～60% of the pond body degree of depth.With respect to prior art, the height of the boss increased in the application, prevent that shower nozzle directly was sprayed onto on filter screen and has reduced the impulse force of current in when water spray.
further, the curvature of any point on the bottom surface of circuit is greater than zero.
further, the boss top is connected with bracing frame, and filter screen is around on this bracing frame and forms a tubular.
further, the tubular that filter screen forms tilts from the bottom to top laterally, prevents that the fish-egg splash with current from sticking on filter screen.
further, the pond body is connected with spawning inducing pool by intake tunnel.
owing to having adopted technique scheme, the utility model fish hatching circuit, the boss sidewall slope arranges, and the degree of depth of having deepened circuit, there do not is the current dead angle in circuit, and in the situation that the constant water velocity that can accelerate in circuit of shower nozzle water spray pressure has solved the problem that fish-egg does not move with current being stuck in place, a certain dead angle.
The accompanying drawing explanation
the perspective view that accompanying drawing 1 is the utility model fish hatching circuit;
the cutaway view that accompanying drawing 2 is the utility model fish hatching circuit.
number in the figure is:
1, pond body; 2, boss; 3, circuit; 4, filter screen; 5, bracing frame; 6, shower nozzle; 7, intake tunnel.
Embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
from accompanying drawing 1 to accompanying drawing, the structural representation of 2 fish hatching circuits can be found out, it comprises pond body 1, be arranged on the boss 2 at pond body 1 center, be connected to the filter screen 4 of boss 2 tops, form circuit 3 between pond body 1 and boss 2, be provided with the shower nozzle 6 of evenly arranging along circuit 3 in circuit 3, on pond body 1, be provided with discharge outlet.
the shape of pond body and size are determined according to production scale, take circular circular hatching channal in the present embodiment as example, and pond body 1 is highly 1.2 meters, and diameter is 3 meters.Pond body 1 is connected with spawning inducing pool by intake tunnel 7, in spawning inducing pool, after Gunther parent fish spawning, opens intake tunnel 7 valves, and fish-egg enters pond body 1 and falls in circuit 3 with current.
the height of boss 2 is pond body 1 degree of depth 40%～60%, in the present embodiment is 0.6 meter, adopts brick and cement to be built into.With respect to prior art, the height of the boss 2 increased in this circular hatching channal, prevent that shower nozzle 7 directly was sprayed onto on filter screen and has reduced the impulse force of current in when water spray.
the magnitude relationship of boss 2 is to the width of circuit 3, and the diameter of boss 2 upper surfaces in the present embodiment is 1 meter.The sidewall of boss 2 is centroclinal to boss 2 from the bottom to top, and the cross section of these circuit 3 in the vertical directions is U-shaped, and the curvature of any point on the bottom surface of circuit 3 is greater than zero.There do not is the current dead angle in circuit, and in the situation that the constant water velocity that can accelerate in circuit of shower nozzle water spray pressure.
above-described embodiment is only explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
