Abstract

The elevating culture net cage consists of a net cage skeleton, netting, connecting pieces and a buoyancy elevating and balancing control system. The net cage skeleton consists of antirust pipes connected into a frame structures, stainless steel pipes connected to the ends of the antirust pipes, high strength plastic pipes outside the antirust pipes and with ends sealed inside the stainless steel pipes. The buoyancy elevating and balancing pipes or barrels are mounted onto the vertical pipes of the skeleton, and may be deflated for the net cage to descend to proper depth or inflated for the net cage to ascend to the water surface.

Description

Net cage elevating and balancing control system and elevating culture net cage

Technical field:

The present invention relates to a kind of elevating culture net cage and elevating balance sysmte.

Technical background:

Fish culture net cage is placed in the seawater throughout the year, be in adverse circumstances among morning and evening tides distinguished and admirable, seawater corrosion is constantly all in the safety that is threatening aquaculture and breeding facility.Nearly 1,000,000 of the coastal fish culture net cage quantity of China, mostly be floating mat formula net cage greatly, this cage structure is simple, and firm inadequately capacity of anti-storm is poor, only be adapted at culturing in the surface seawater, because wind resistance stream ability makes fish culture net cage concentrate in waters, bay, coastal waters or the enclosed bay, the water exchange rate is low, cause cultivation density to surpass carrying capacity of environment, cause breeding environment to worsen, cause disease frequently to take place, cause enormous economic loss.

Summary of the invention:

The invention solves the following up and down balance system depth localization control technology of the lifting net cage water surface.

The technical solution used in the present invention is that the cage fish culture net cage adds elevating and balancing control system.

This lifting net cage is by Net-cage frame, and cage netting, net cage elevating and balancing control system are formed, Net-cage frame is to do arm with the antirust steel pipe of high-quality to connect into frame structure.There is the stainless steel tube of suitable length at arm two; the silk mouth docked with the framework connector about be processed at two of whole arm; whole arm puts High strength plastic pipe, and two of plastic tube is sealed on the stainless-steel pipe, and this measure protection steel pipe prevents by the buoyancy of seawater corrosion and increase arm.Elevating balance pipe or tube (abbreviation fall way) are arranged in the periphery of net cage respectively in order.Fall way more than 2 is one group, 4 groups of fall ways are a cover, each net cage uses a cover fall way, the buoyancy big more or fall way that net cage is done is more little, it is many more to make the used pipe number of one group of fall way, 1., 2., 3., 4. one group of fall way is respectively according to the length or the height numbering of air inlet-outlet pipe or porting ... as shown in Figure 1,1. 2. 3. 4. arranging all around of net cage be respectively so ... 1. 2. 3. 4. ... 1. 2. 3. 4. ... 1. 2. 3. 4.

Fall way 1. 2. 3. 4. ... the length of air inlet-outlet pipe is according to net cage gross weight and net cage gross buoyancy in each pipe, net cage in the water surface, water, the equilibrant force that calculates of position separately under water, try to achieve the difference in height of fall way porting.The Net-cage frame cross section can be made into circle or polygon; the Net-cage frame arm interconnects, and forms the integral sealing structure, can prevent that seawater from entering the tube inner corrosion tube wall; fall way is enclosed within on the standpipe that is with the protection of High strength plastic pipe do, and cage netting adopts the slidingtype fixation to be fixed on the fall way.

The elevation (over-and-under) type fish culture net cage possesses following advantage:

1, can just regulate and control net cage according to stormy waves size or summer, winter surface temperature bubbles through the water column or rests on any degree of depth in the water.

2, durable, corrosion-resistant, intensity is high, anti-12 grades of typhoons, long service life, cost is low without timber.

3, the draping of fishing with a net is easy to operate, but 1 people's normal running, and practicality is wide, can culture upper, middle and lower layer fingerling.

Accompanying drawing 4: positive ten hexagon lifting net cage cross-sectional views.

1. 2. 3. 4.---the distribution map of elevating balance pipe or tube.

Embodiment:

To make installation one cover positive ten hexagonal elevating culture net cages is example: select for use the antirust steel pipe of high-quality to do arm, arm two connects the stainless steel tube of suitable length, two of the outside suit high strength of whole Zhi Gangguan HDPE pipe (high density polyethylene pipe) HDPE pipe is in the stainless steel tube sealing at arm two, and the stainless steel tube at two leaves joint.Press 1. 2. 3. 4. in the elevating balance pipe that net cage is used (abbreviation fall way) accompanying drawing 4 ... 1. 2. 3. 4. ... 1. 2. 3. 4. ... 1. 2. 3. 4. ... equidistant row is contained on the standpipe of net cage.Be connected to each other fall way or the outer porting of tube, the porting joint is connected on the gas main at last, house steward's length outline is longer than the degree of depth of sea area seawater, the deep sea diving dedicated pipe that tube connector wears out with high strength anti, gentle the chewing of other end dress two pass anticorrosion one control air valve of gas main, and buoy on the bolt.

When descending, opens by net cage the venting of two pass air valve, fall way begins water inlet from the bottom, the fall way that 1. lifting around the net cage extensively indicates number is at first sealed on the seawater plane, because 1. the air inlet-outlet pipe in number fall way is the longest, because the effect of net cage gravity and seawater pressure, the water surface in the fall way is higher than exhaust outlet, at this moment the seawater above part of air inlet-outlet pipe of having sealed fall way makes fall way 1. become buoyancy tube, because 1. pipe is distributed in four orientation (as accompanying drawing 4) over against title of net cage, 1. fall way at first plays the effect of balance net cage, the intake and exhaust house steward continues venting, net cage continues to descend, at this moment seawater has been sealed the 2. interior above part of air inlet-outlet pipe of fall way again, 2. fall way has become buoyancy tube again, because 2. fall way also is distributed in positive four orientation (as accompanying drawing 4) of net cage, so net cage is many again one counterweighting arrangement, and the like ... you need net cage to stop at any position in the water, as long as the intake and exhaust amount of control gas main just can easily be implemented.
