Description
Technical Field
The invention relates to the technical field of aquaculture, in particular to an aquaculture net cage.
Background
In the last 70 th century, cage culture has begun in China, and because of the characteristics of low investment, high yield, mobility, quick response and the like, the cage culture is developed vigorously in lakes and reservoirs all over the country in short decades.
The net cage is generally positioned in a depth area with the water depth of about 3-7 m, when water rises, workers need to shift the net cage to other shallow water areas, and in the moving process of the net cage, fishes in the net cage are easy to collide with a net, particularly young fishes which are just put in the net cage are tender in skin and easy to scratch;
the fish are in long-term growth in-process, and the excrement of discharging has all directly fallen into the bottom, becomes submarine nourishment, impels a large amount of marine alga biology mad growth, not only influences quality of water and still wastes natural fertilizer for the manual work can't be collected it and make other fertilizers and supply the agricultural use.
Disclosure of Invention
Aiming at the defects of the background technology, the invention provides the technical scheme of the aquaculture net cage, which has the advantages of automatically adjusting the depth state of the net cage according to the lifting condition of the water level and collecting natural nutrients generated by fishes, and solves the problems in the background technology.
The invention provides the following technical scheme: the utility model provides an aquaculture net case, includes the case frame and can dismantle the netting of connection on the case frame, the case frame both sides all overlap and have the flotation pontoon that is located the surface of water, the bottom rigid coupling of flotation pontoon has the telescopic connecting rod, the bottom rigid coupling of connecting rod has the protective frame who overlaps on case frame surface, protective frame has been seted up on protective frame's surface, protective frame is located the bottom of netting, the bottom of netting is through connecting the bottom of rope rigid coupling at protective frame, the surperficial rigid coupling of case frame has supporting role's mount.
Preferably, the diameter length of the protective frame body at the bottom of the protective frame is smaller than the diameter length of the protective frame body arranged around the protective frame.
Preferably, the protection frame has a certain height.
Preferably, the width of the net is smaller than that of the protection frame, and two sides of the net are not in contact with two sides of the protection frame.
Compared with the prior art, the invention has the following beneficial effects:
1. the aquaculture net cage is characterized in that the bottom of the buoy is in contact with the water surface through the buoy, the connecting rod, the protection frame and the protection frame body, when the water level rises, the buoy rises along with the rise of the water level, and when the buoy rises upwards, the protection frame and the net are pulled to rise through the connecting rod; when the water level descends, the buoy descends along with the water level, then the protective frame and the netting simultaneously descend to the water level suitable for fish survival through the connecting rod, the box body can be automatically lifted and adjusted to the water level area suitable for fish survival according to the rising and descending of the water level, and manual removals are not needed.
2. The aquaculture net cage is convenient for collecting fish excrement through the arranged protective frame body, prevents the fish excrement from directly entering the water bottom and changing into water bottom nutrient, promotes the algae and duckweed to grow vigorously, and is easy to influence water quality to cause water pollution;
the protective frame has a certain height, so that the fish in the protective frame can be prevented from escaping due to the attack of other organisms at the water bottom on the fish and the bite of the bottom of the netting, and meanwhile, some algae in the deep sea can be prevented from attaching to the surface of the netting, so that the weight of the box body is increased, and manual net collection is influenced;
and when the aquatic organisms impact the surface of the protective frame, the algae attached to the surface of the protective frame can be automatically separated from the surface of the protective frame under the impact force, so that the influence on water body exchange is avoided, and the oxygen supply required by fishes is facilitated.
