A kind of plug-in fish culture net cage
Technical field
The invention belongs to cultivation field, relate to a kind of plug-in fish culture net cage.
Background technology
Aquaculture is the activity in production of breeding, cultivating and gather in the crops aquatic animals and plants under manual control.Generally comprise the overall process forming aquatic products under artificial feeding management from seed.Broadly also Enhancement of fishery resources can be comprised.Aquaculture has the modes such as extensive cultivation, intensive culture and high density culture.Extensive cultivation throws in seed in medium and small natural water area, forms aquatic products completely by natural bait, as lake and reservoir breed fish and shallow sea support shellfish etc.Intensive culture forms aquatic products with bait throwing in, fertilizing method, as aqiuculrue, fish culture in net pen and enclosure culture, net enclosure culture etc. in comparatively small size pond.High density culture adopts flowing water, temperature control, oxygenation and the methods such as high-quality bait of throwing something and feeding, and carries out high-density breeding in small size pond, thus obtains high yield, as Running Water Intensive Fish Farming, shrimp etc.
Have in current aquaculture and undertaken cultivating by net cage mode, the net cage that current cage culture mode adopts is that lower end is positioned under water substantially, upper end is positioned on horizontal plane, the fixing of net cage is realized by anchor, upper end by net cage realizes feeding intake fishing with a net, there are some problems in existing net cage, when meeting wind and waves weather, because the upper end of net cage is being positioned at above horizontal plane, when blowing, net cage has the larger power that is critical, water-bed anchor is easily made to be started, net cage is turned on one's side, the fish in net cage are caused to run away, cause economic loss, there is fault of construction in net cage current as can be seen here.
Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, provide a kind of plug-in fish culture net cage, this plug-in fish culture net cage can prevent net cage from turning on one's side, smart structural design, easy to operate, solve existing aquaculture net box structure existing defects, easily by problems such as weather effects.
Object of the present invention realizes by following technical proposal: a kind of plug-in fish culture net cage, it is characterized in that: described net cage comprises clamping apparatus and the upper net cage all in annular and lower net cage, described upper net cage is positioned on the water surface, described lower net cage is positioned at underwater, described clamping apparatus is positioned at described lower net cage, described clamping apparatus is one in the air bag of annular, on the inwall being connected in described lower net cage upper end of the outer wall of described air bag, the external diameter of described upper net cage is less than the internal diameter of described lower net cage, the lower end of described upper net cage can be placed on described air bag, described air bag has gas tube, the inner of described gas tube is communicated with described air bag, the outer end of described gas tube passes described lower net cage sidewall and protrudes upward the water surface, the outer end of described gas tube has ball valve, the length of described upper net cage is less than the length of described lower net cage, the two bottom sides of described lower net cage is provided with several linear electric motors, the motor housing of described linear electric motors is fixed on bottom described lower net cage, the two bottom sides place of described lower net cage has installing hole respectively, the linear axis of described linear electric motors puts in described installing hole and corresponding with the position of described upper net cage.
The roughly use procedure of this plug-in net cage and principle as follows: when normally cultivating, air bag is in inflated condition, now go up net cage can be stuck on the air bag of inflation, can not drop in lower net cage, convenient normal cultivation, when meeting bad weather, when net cage has rollover dangerous, open ball valve and make bladder deflates, now go up net cage lower end not against thing, drop in lower net cage, now whole net cage is all in underwater, the impact of wind-force can not be subject to, well maintain the stability of net cage, now need to carry out capping to the upper end port of lower net cage, prevent fish from runing away, when weather improvement needs to take out upper net cage, start linear electric motors, linear axis rises and upper net cage is ejected the water surface, again air bag is inflated, can upper net cage be stuck on air bag again, restore to the original state, design very ingenious.This net cage, by the inflation/deflation of air bag and the effect of linear electric motors, achieves the function that net cage state changes, easy to operate, shifts without the need to the artificial net cage by heaviness, very convenient, has stronger practicality.
In above-mentioned a kind of plug-in fish culture net cage, have the protection portion in annular in described lower net cage, the lower end of described protection portion is fixed on bottom described lower net cage, and the upper end of described protection portion is positioned at the below of described air bag.
When caisson sinking of surfing the Net enters in lower net cage, fish may be had and be on the movement locus of online caisson sinking, directly sink can kill fish, avoid this situation by the setting of protection portion, the safety of fish can be protected.
In above-mentioned a kind of plug-in fish culture net cage, the quantity of described linear electric motors is 2.
Two linear electric motors act on the both sides bottom net cage respectively, thus are ejected by upper net cage.
In above-mentioned a kind of plug-in fish culture net cage, there is between described linear electric motors the connector in " T " font, one end of described connector is fixed on the bottom of described lower net cage, and the other two ends of described connector are fixed on the motor housing of described linear electric motors respectively.Can to make under being connected to that linear electric motors are firm on net cage by connector.Compared with prior art, this plug-in fish culture net cage has the following advantages: 1, this plug-in fish culture net cage shifts without the need to the artificial net cage by heaviness, very convenient, has stronger practicality.
2, this plug-in fish culture net cage is when weather improvement needs to take out upper net cage, starts linear electric motors, and upper net cage is ejected the water surface by linear axis rising, then inflates air bag, can be stuck on air bag by upper net cage again, restores to the original state, designs very ingenious.3, this plug-in fish culture net cage is by the inflation/deflation of air bag and the effect of linear electric motors, achieves the function that net cage state changes, easy to operate.
4, this plug-in fish culture net cage avoids fish by the setting of protection portion and to be crushed to death this situation, can protect the safety of fish.
5, this plug-in fish culture net cage achieves operation automation, greatly reduces manual labor.
