Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of wind wave-resisting net casing.
Background technique
With the rapid development of deep-water net cage culture industry, deep-water net cage culture produces significant economic results in society.It is existing
It is mainly made of etting, frame and fixed device for net cage, net cage is positioned by fixed device and seabed seashore, deep water mesh cage
It is generally fixed using surrounding stake, stake uses connection rope to connect net cage frame again by the fixed floating drum that first connects, to ensure to fix
The stress equalization of stake.
Current -resistance submerged cage refers to using the large size sea with stronger capacity of anti-storm for being arranged in 15 meters of the depth of water or more
Upper breeding facility.Its function has effectively expanded aquaculture sea area, improves aquatic products quality.Current -resistance submerged cage is possessing more preferably
Cultivating condition while, also bring bigger self weight, stronger wind, unrestrained environmental load condition.
Summary of the invention
The purpose of the present invention is to provide a kind of wind wave-resisting net casings, and the sinking of net cage is controlled by water flow flowing velocity, resist
Stormy waves ability is strong, while the deposition that also can avoid feed causes the generation of the eutrophication and fish disease in sea area, effectively improves
Breeding environment promotes the growth of aquatic products.
The scheme that the present invention is taken to achieve the above object are as follows: a kind of wind wave-resisting net casing, including etting, water conservancy driving group
Part, frame, dirt collection component, connection framework at the top of etting, the two sides of frame are by drawstring connection water conservancy driving assembly, inside etting
Equipped with dirt collection component, the outer ring of dirt collection component is connected with inclined plate one end, and the inclined plate other end connects etting.Wind and wave resistance net of the invention
Case generates driving force to water conservancy driver by the flow velocity of seawater, and control net cage sinks, when net cage sinks down into deep place
Preferable wind and wave resistance effect is played, the dirt collection component inside etting can guide extra bait and can be worn into small
Grain avoids the deposition of bait from causing the eutrophy in sea area, improves breeding environment, promote convenient for going out outside net cage together with water flow
Into the growth of aquatic products.
Preferably, etting bottom is connected with connecting line, connecting line end connects free suspending weight body, free suspending weight body following table
Face is connected with from mooring cable, is connected from mooring chain end from mooring ballast.The suspending weight body of etting bottom connection with from mooring ballast
The position in the water of net cage is secured, the security performance of net cage will not be improved because of the excessive displacement for leading to etting of stormy waves.
Preferably, being equipped with air cushion above frame, top net is equipped with above air cushion, the surrounding for pushing up net connects frame by stretch cord
The quadrangle of frame.Air cushion above frame is in inflated condition under normal circumstances, and what air cushion was crossed by top Netcom is supported in frame roof
Be detached from, in inclement weather, the gas in air cushion be discharged rapidly, by the tightening force of stretch cord make top net it is tight be placed on frame
Above frame, it is therefore prevented that the aquatic products that net cage cultivates after sinking are escaped from the top of etting, are avoided the unnecessary economic loss of fisherman, are mentioned
The high practicability of device.
Preferably, water conservancy driving assembly includes roller bearing, it is arranged with winding roll in the middle part of roller bearing, roller bearing both ends are plugged in shell
Side wall, the surface loop of roller bearing is furnished with driving blade, and winding roll passes through drawstring connection framework.Net cage of the invention utilizes water flow band
The energy come can push driving blade rotation when water flow reaches certain speed automatically, and driving blade rotation while is sheathed on rolling
Winding roll in the middle part of axis can also rotate, and the drawstring being wrapped on winding roll in rotary course can lengthen rapidly, make net cage generate to
Under power, so that net cage is sunk, compared with traditional decanter type net cage, this net cage is easily managed, the sedimentation of net cage and the speed of water flow
It is related,
Preferably, etting includes outer nettle and interior nettle, connected between outer nettle and interior nettle by connecting plate, connecting plate table
Face is equipped with baffle.Etting is made of outer nettle and interior nettle, the two by connecting plate connect, strengthen net cage stability and
Wind and wave resistance performance avoids net cage and deforms because being impacted by stormy waves, ensure that the capacity of net cage and the safety of aquaculture organism, connects
Plate surface is triangular in shape equipped with baffle, and the impact force by seawater is smaller, can make the exchange of seawater inside and outside net cage, formation pair
Stream is beneficial to improve breeding environment while increasing to water disturbance.
Preferably, dirt collection component is cone, and the upper opening of dirt collection component and the size of under shed ratio are 5-0.5,
Dirt collection component includes the string bag, and string bag bottom is connected with web plate, is welded with blowdown mouth below web plate.Dirt collection component be used for residual bait,
