Abstract
The utility model relates to a water inlet device for a fry-rearing pond. The water inlet device comprises slings (1) and a net cylinder, wherein the net cylinder is formed by welding a plurality of rebar rings (2) and a plurality of steel bars (3); the rebar rings (2) are arranged from top to bottom at equal intervals in a parallel way, and the steel bars (3) are vertical to the rebar rings (2) and are arranged on the peripheries of the rebar rings (2) at equal intervals; sieve nets (4) are sleeved on the peripheral surface and the bottom surface of the net cylinder from outside; and the slings (1) are fixed by the uppermost rebar ring of the rebar rings (2) along the diameter direction. The water inlet device can prevent fries from swimming into a position with a strong impact below a water inlet and offset the strong impact of the water flow discharged by a water inlet pipe, so as to be beneficial to reducing the damage of the strong impact to pomfret fries in process of water feeding.
Description
Technical field
The utility model belongs to the water inlet technology field of aquaculture nursery pond, particularly relates to a kind of juvenile fish and cultivates the pond water feed apparatus.
Background technology
Silvery pomfret is very wide in the coastal distribution of China, and it has higher economic value.In recent years, because overfishing and ecological degeneration, its wild resource reduces gradually.Therefore, carrying out the artificial increasing cultivation becomes inevitable.At present, the researcher is doing a lot of work aspect the silvery pomfret breed both at home and abroad, and has obtained certain progress.But still there are many problems in the cultivation of its young, causes its larvae juvenile fish lethality very high.Usually, when juvenile fish was cultivated, the water inlet position in pond was too high, even increase water inlet pipe, it was down extended, and also caused pond water fast rotational easily, and these all can make the juvenile fish of breed suffer bigger impulsive force, thereby influence the health of juvenile fish and survive.Therefore, need a kind of water feed apparatus that can as far as possible reduce to the juvenile fish impulsive force.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pomfret parr and cultivates the pond water feed apparatus, the injury that the enormous impact power in the time of can reducing fast quick change water by this water feed apparatus causes juvenile fish.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of juvenile fish to cultivate the pond water feed apparatus, comprise lanyard and net tube, described net tube is welded by equidistant several reinforcing bar annulus that are arranged in parallel from top to bottom and and some steel bars that equidistantly distribute on its circumference vertical with the reinforcing bar annulus, described net tube periphery and bottom surface be by being with screen cloth outward, and described reinforcing bar annulus is positioned at uppermost reinforcing bar annulus along the fixing lanyard of diametric(al).
Described net tube is positioned at the water inlet below.
Described lanyard is a nylon rope.
Described reinforcing bar annulus is 3.
Described steel bar is 6.
The diameter of described net tube is 20cm; Tube length is 80cm, and the diameter of steel bar and the used reinforcing bar of annulus is 1cm.
Beneficial effect
The utility model can stop juvenile fish to be swum into the water inlet of strong impact force below, and the strong impulse force that water inlet pipe is discharged current is balanced out, and helps reducing the injury that the strong impact force in the water inlet process causes pomfret parr.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, the utility model comprises lanyard 1 and net tube, described net tube is welded by equidistant several reinforcing bar annulus 2 that are arranged in parallel from top to bottom and and some steel bars 3 that equidistantly distribute on its circumference vertical with reinforcing bar annulus 2, described net tube periphery and bottom surface be by being with screen cloth 4 outward, and described reinforcing bar annulus 2 is positioned at uppermost reinforcing bar annulus along the fixing lanyard 1 of diametric(al).
The utility model is cultivated the pond juvenile fish water inlet pipe mouth place hangs a net tube with nylon rope, and the net tube is made up of 2,6 steel bars of 3 reinforcing bar annulus 3 and screen cloth 4.The equidistant parallel placement of reinforcing bar annulus, being weldingly connected by vertical steel bar forms tubular, its outer screen cloth that is with, the net barrel structure of opening above forming.The diameter of the net tube of the utility model below water inlet is 20cm; Tube length is 80 cm.The diameter of steel bar and the used reinforcing bar of annulus is 1cm.Place juvenile fish to cultivate under the water pipe of water inlet in pond the utility model, and be fixed under the water pipe with nylon rope.Like this, when water inlet pipe was opened quick water inlet, the net tube stoped juvenile fish to enter below the current with strong impact force; Simultaneously, water inlet vertically enters the net tube, to disperseing, has also weakened impact force of water flow all around behind the water surface below impacting, and juvenile fish is had the certain protection effect.
Claims (6)
1. a juvenile fish is cultivated the pond water feed apparatus, comprise lanyard (1) and net tube, it is characterized in that: described net tube is welded by equidistant several reinforcing bar annulus (2) that are arranged in parallel from top to bottom and and some steel bars (3) that equidistantly distribute on its circumference vertical with reinforcing bar annulus (2), described net tube periphery and bottom surface be by being with screen cloth (4) outward, and described reinforcing bar annulus (2) is positioned at uppermost reinforcing bar annulus along the fixing lanyard (1) of diametric(al).
