Description

Submerged and floated type deep sea network

The utility model is a kind of Submerged and floated type deep sea network, is used for the mariculture industry, belongs to the operation technique field.

It is to develop very fast a kind of novel mariculture technology over nearly 10 years that Deep sea net cage is cultured.Net cage of the prior art mostly is floating structure, and this floating cage can only float on the surface, and typhoon, billow are not had the ability of evading, and in actual applications for guaranteeing the net cage capacity of anti-storm, requires it can slip under the sea before wind and waves arrives.

The purpose of this utility model is at the deficiencies in the prior art and actual needs, design provides a kind of novel deep-sea net of diving, make it by pre-provisioning request reliably float, dive, solve the influence of bad weather to the cage culture industry, guarantee the safety that culture at the typhoon season deep-sea.

For realizing such purpose, the utility model provides a kind of submersible floating deep-sea net of diving, the net of diving is made up of the annular buoyancy circle that two hollow PE pipes constitute, the outer ring is adjustable buoyancy circle, inner ring is the fixed buoyancy circle, and Internal and external cycle is fixed by the connector as rail support, and blow vent upwards and downward maritime mouth are housed on the outer ring, to the float-ball type control valve of particular design all is housed in the maritime mouth of top blow vent and bottom, to guarantee that the buoyancy circle still can normally float at the high inclination-angle state, dive.The suitable counterweight of net circle configuration.When sky is blown in the outer ring, promptly to discharge seawater buoyancy is provided with compressed air, the net circle floats on the sea, and after the exhaust water filling of outer ring, the net circle promptly slips into appropriate depth.

Below in conjunction with accompanying drawing the technical solution of the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

As shown in the figure, the net of diving is made up of the buoyancy circle of two hollow PE materials, outer ring 3 is adjustable buoyancy circle, inner ring 4 is the fixed buoyancy circle, outer ring 3 and inner ring 4 are by fixing as the connector 2 of rail support and be connected with railing 1, blow vent 5 upwards and downward maritime mouth 6 are housed on the outer ring 3, the float-ball type control valve of particular design all is housed in the maritime mouth 6 in top blow vent 5 and bottom, the suitable pouring weight 8 of lower end configuration of net circle 7.

Fig. 2 is the structural representation of float-ball type control valve in the maritime mouth of the utility model ventilation.

The annular adjustable buoyancy circle that outer ring 3 shown in the figure constitutes for hollow PE pipe, ventilation on the buoyancy circle (upwards is blow vent 5 for maritime mouthful, be maritime mouthfuls 6 downwards) locate to be equipped with control valve, one " O " type circle 10 is arranged on the valve body 9, a ball float 11 is arranged in the valve body 9, be filled with seawater or compressed air in the buoyancy circle.

When buoyancy circle 3 maritime interior waters are full of, ball float 11 come-ups, in compressed air entered circle, the circle internal pressure raise, and ball float 11 closes dead blow vent 5 automatically, stops compressed air to overflow from suitable for reading.As this valve oppositely is installed on the hollow tube bottom, maritime mouthful of control, when seawater is discharged, water level depression is promptly closed maritime mouthful during to maritime mouthful of ball float contact automatically, prevents that equally compressed air from overflowing.When buoyancy circle 3 internal pressures were reduced to certain value, the blow vent ball float fell down and opens blow vent under self-gravity action, and maritime mouthful of seawater pours in and back down automatically and float ball float, so this floater controlled valve does not influence the heavy action off the net of diving.

Fig. 3 has stayed under water in undersea view for latent net of the present utility model.

As shown in the figure, latent net stays under water in (about about 5 meters) below the sea, the buoyancy circle 3 of hollow PE pipe is equipped with up-draught mouth 5 and downward maritime mouth 6, latent net has a gas tube 12 to connect blow vent 5, has been full of seawater, loss of buoyance in the buoyancy circle 3, the net of diving is lowered into marine at the gravity of pouring weight 8, lose the downward pulling force of pouring weight when pouring weight 8 lands, the net net circle 7 of diving is at fixing surplus buoyancy effect low suspension about 5 meters under the sea, the still moulding of latent net.

Fig. 4 is the view of the net beginning floating-upward process of diving.

In the buoyancy circle, charge into compressed air through gas tube 12, under pressure, blow vent a, b, c, d close automatically owing to special floater controlled valve, and compressed air extrudes buoyancy circle maritime interior waters through maritime mouthful of A, B, C, D, net circle buoyancy increases and begins come-up, and high inclination-angle occurs.The interior top of buoyancy circle this moment is a gas, is seawater in the bottom, and when water level face in the circle dropped to maritime mouthful of A, D successively, because the effect of floater controlled valve, these two maritime mouths will be closed successively automatically, destroy blowing to prevent compressed air from overflowing and normally carry out.

Fig. 5 continues the view of come-up to the sea for the net of diving.

Under the compressed air effect, buoyancy circle maritime interior waters continues to discharge through maritime mouthful of B, C, and the net buoyancy of diving constantly increases and the emersion sea, and its inclination angle reduces under the freeboard effect, and as shown in the figure, buoyancy circle maritime interior waters is most of discharges.

Fig. 6 has finished floating-upward process for the net of diving, and floats on the view on sea.

Under the compressed air effect, buoyancy circle maritime interior waters continues to discharge through maritime mouthful of B, C, when water level face in the circle drops to maritime mouthful of B, C, same because the effect of floater controlled valve is closed automatically, and this hour circle maritime interior waters is about 95% above emptying, because maritime mouth and blow vent are all closed, the stable water surface that swims in of the net of diving, can stop inflation this moment, and the stop valve on water surface manual-lock blow vent, and the net long-term stability of can guaranteeing to dive is in floating state.

It is off the net heavy to dive as need, then a need water surface is opened the stop valve on the blow vent, blow vent and maritime mouthful of floater controlled valve all can be opened automatically, and this moment, seawater entered through maritime mouth, and air is discharged through the top blow vent, latent net buoyancy circle loss of buoyance, under the pouring weight effect, will be slowly submerged, land and be returned to Fig. 3 state until pouring weight, (5 meters below the sea, stormy waves is very little to the influence of the net of diving to resist the stormy waves impact.

The utility model adopts hollow PE pipe to make the variable buoyancy circle, discharges seawater with compressed air buoyancy is provided, and adopt the float-ball type control valve of particular design, guarantees that buoyancy circle high inclination-angle state still can normally float, dive.Design concept is ingenious, technology and simple in structure, and material therefor can guarantee that efficiently and effectively has improved the capacity of anti-storm of latent net in the medium-term and long-term work of seawater, guarantees the security reliability that culture at the multiple regional deep-sea of typhoon, has development prospect widely.
