Abstract
The invention discloses an underwater lift adjusting device for enabling a net cage to resist wind waves. The underwater lift adjusting device for enabling a net cage to resist wind waves consists of an upward-floating body, a bolt mechanism, a lift propeller mechanism, a net cage sinking/floating guide pile, an underwater screw anchoring mechanism, a seafloor base and a balancing weight. The main connection way of the device is as follows: the upper end of the net cage sinking/floating guide pile is connected with the upward-floating body through the bolt mechanism, the lower end is fixed with the seafloor base in a welding way, and the underwater screw anchoring mechanism is sleeved at the lower end of the net cage sinking/floating guide pile in a slip connection mode. ccording to the invention, the net cage can be anchored on the seafloor through the screw anchor, the underwater depth of the net cage can be adjusted through the propeller, and the stable and balanced towing displacement can be realized through the upward-floating body and seafloor base, thereby achieving the aim that the net cage can be fixed on the seafloor or moved away and the underwater lift can be adjusted and controlled; and the device has the advantages of simple operation process and low construction cost, is safe and reliable, and can be easily accepted by common farmers.
Description
Technical field
What patent of the present invention related to is the device of resisting the lift adjustment under water of stormy waves for net cage, belongs to mechanical field.
Background technology
That cage culture has is intensive, high density and high benefit characteristics, and development prospect is very wide.Entered since the nineties in 20th century, China's seawater cage culture development has produced significant economic results in society rapidly.But at present cage culture also faces many problems, and one of them is because the effect of stormy waves, typhoon often causes net cage displacement, the scratch of cultivation fish, escapes, even net cage and breeding facility suffer thorough damage.Wherein two be that environmental pollution, virus are wreaked havoc, insect pest is rampant, caused great economic loss for numerous fishermen, " the three large killers " of culture fishery, aquatic science and technology worker's a tackling key problem difficult problem and numerous fishermen's maximum worry have been become, seriously restricted the development of fish production power, the enthusiasm for production of greatly having dampened numerous fishermen.For avoiding the loss of these natural calamities, the mode that usually adopts piling or net cage to sink.Yet this dual mode also exists some major defects: 1. net cage towage displacement is inconvenient, the cultivation waters suffer external or the situation such as net cage self-pollution under, cause that easily fish diseases occurs.2. piling is fixing, not only needs marine specialty piling facility, and the construction cost expense is high, and the pile body of squeezing into the seabed reclaims also inconvenient.3. the sunk type net cage is located by anchor, the marine installation and fixing the requirement very strictly carefully, and the quality that net cage installs and fixes with directly having influence on the from now on normal use of net cage, is finished by diver's cooperating ship fully jointly.4. the deep water mesh cage lifting technology is not yet ripe, and the net cage submergence depth is difficult to control.Deep water mesh cage is away from the bay in the neritic province domain cultivation, the breeding production cost increases, disperse the breeding production operation, general human and material resources, financial resources all are restricted, the raiser be in power difficult and the condition, cultured product is sold by single household and also is difficult to open up markets, and raiser's enthusiasm for production is baffled.A kind of underwater lift adjusting device of resisting stormy waves for net cage has been proposed for this reason.
Patent of the present invention designs for addressing the above problem just, and it is complicated that purpose is effectively to solve present net cage offshore construction program, and the difficult problem that operating cost is high realizes that convenient the adjusting with the seabed of net cage operating depth fix.When especially big typhoon, allow in the net cage cascading water, avoid billow to the direct impact of net cage.Under cultivation water environment unfavorable condition, can in time shift the cultivation marine site, avoid cultivating the object illness outbreak, spread, or unexpected Large Scale Death, improve the quality that cultivates water environment, promote the sustainable development of aquaculture.
Summary of the invention
The technical problem that patent of the present invention will solve provides a kind of underwater lift adjusting device of resisting stormy waves for net cage, this device can realize that the net cage operating depth is conveniently regulated and the seabed is fixed, reduce the offshore construction operating cost, the destroying infection of avoiding stormy waves and polluted water region environment that cage culture is become.The purpose of patent of the present invention is to provide a kind of safe and reliable lift adjustment under water and fixing protector for cage culture.
For addressing the above problem, patent of the present invention is achieved in that patent of the present invention mainly comprises upper float, bolt mechanism, elevating screws pulp grinder structure, sinking floating net cage direction peg, under water helical anchor mechanism, seabed pedestal and balancing weight, the upper end that it is characterized in that the sinking floating net cage direction peg is connected with upper float by bolt mechanism, and the lower end of sinking floating net cage direction peg and seabed pedestal fix by welding manner; Elevating screws pulp grinder structure is evenly arranged on the upper float; Helical anchor mechanism is sleeved on the lower end of sinking floating net cage direction peg in the mode that is slidingly connected under water; The seabed pedestal is provided with balancing weight.
This net cage underwater lift adjusting device specific works program is as follows:
1. submarine anchoring, water filling in the pedestal of seabed sinks down into the seabed so that the seabed pedestal drives the sinking floating net cage direction peg.Then start helical anchor mechanism under water, whole seabed pedestal is anchored in the seabed.
2. lift adjustment when meeting high sea weather, is filled with Ballast Water with upper float, then starts the elevating screws paddle mechanism, drives upper float and drops to desired depth, by bolt mechanism upper float and sinking floating net cage direction peg is locked at last.
3. seabed floating, the first step is with upper float and the locking of sinking floating net cage direction peg; Second step starts helical anchor mechanism under water, and anchor is screwed out from the seabed; The 3rd step was discharged the Ballast Water in the pedestal of seabed, regulated simultaneously the Ballast Water in the upper float, floated from the seabed so that the seabed pedestal drives the sinking floating net cage direction peg.
4. net cage towage displacement by adjusting Ballast Water in the upper float, reaches the net cage overall structure and is in best condition of stability, then carries out net cage towage displacement.
Patent of the present invention relies on Screw Anchor to realize the net cage submarine anchoring, relies on screw to realize the net cage underwater depth adjustment, relies on upper float and seabed pedestal to realize that the towage displacement is steadily balanced, can reach net cage seabed seat must live, move to such an extent that walk, lifting under water can be regulated, controllable purpose, it is simple to have operation, construction cost is low, safe and reliable advantage.The screw-propeller lifting technology of patent of the present invention and Screw Anchor be technology fixedly, is based on China's national situation, is accepted by general raiser easily, has very high Industry Promotion using value.
