Culture unit in marine culture system

Technical Field

The invention belongs to the technical field of mariculture, and relates to a culture unit in a mariculture system.

Background

Raft culture makes important contribution to marine culture in China and is one of the main modes of marine culture in China. Although the raft culture scale of China is the first in the world, most of the mariculture activities of China are mainly concentrated in shallow water areas with deep lines of-15 meters and the like near the bank and water areas between deep lines of-15 meters and 40 meters and the like, but as the sea areas have large wave and are not easy to erect raft culture equipment, the research on the wind wave resistant technology of raft culture equipment in water areas of high sea conditions is urgently needed to be carried out, a new culture space is expanded, and the major requirements on the healthy and continuous development of marine fishery are met.

In order to solve the problems, Chinese patent CN 101438685A discloses a movable bottom raft type culture system, which is formed by connecting a main rope, a floating ball string, an anchor rope, a culture cage, a weight, an iron anchor, a fixed floating ball and a marking floating ball, wherein one end of the anchor rope is connected with the main rope, the other end of the anchor rope is connected with the iron anchor, the floating ball string is uniformly tied on the main rope, the two ends of the main rope are respectively provided with the weight, the fixed floating ball and the fixed floating ball connecting rope are arranged at proper positions of the anchor rope, and the culture cage and the marking floating ball are also tied on the main rope. This farming systems adopts the bottom cultivation mode, is favorable to improving raft farming systems's anti-storm performance under the typhoon weather, fully develops bottom cultivation sea area.

However, the above-mentioned culture system still has the following problems:

the cultivation cages are always arranged in a straight line, and if the direction of water flow is just vertical to the arrangement direction of the cultivation cages, each cultivation cage can be subjected to large impact force, overturning easily occurs, and the stability is poor.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and provides a culture unit in a marine culture system, which aims to solve the technical problems that: how to improve the stability of the cultivation cage in the cultivation system.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a breed unit among mariculture system, its characterized in that, mariculture system is including floating the circular kickboard on the sea, the centre of a circle department vertical fixation of circular kickboard has the bracing piece, breed the unit including rotating cantilever one and the cantilever two that sets up on the bracing piece, be provided with on the circular kickboard and drive respectively cantilever one and cantilever two are around bracing piece wobbling drive arrangement one, the outer end of cantilever one and cantilever two all extends to the circular kickboard is outer and be connected with outer hawser, the centre of a circle department of face is provided with interior hawser under the circular kickboard, the lower extreme of outer hawser and interior hawser is provided with outer hawser and interior hawser respectively, be connected through the main rope between outer hawser and the interior hawser, be connected with the breed cage on the main rope.

The working principle is as follows: when the marine culture system is used, the culture cages are arranged on the main ropes, if the water flow direction is just vertical to the linearly arranged culture cages, the cantilever I and the cantilever II can be driven by the driving device to swing around the supporting rod, and the angles formed by the cantilever I and the cantilever II and the water flow direction are adjusted; the retraction of the outer anchor rope and the inner anchor rope can be driven by a winch.

In the culture unit in the marine culture system, a first annular protrusion and a second annular protrusion are fixed on the support rod along the height direction of the support rod, a first lantern ring sleeved on the support rod is arranged at the inner end of the first cantilever, the lower end surface of the first lantern ring is movably matched with the first annular protrusion, and a first gear is coaxially fixed on the outer peripheral surface of the first lantern ring; the inner end of the cantilever II is provided with a second lantern ring sleeved on the supporting rod, the lower end face of the second lantern ring is movably matched with the second annular bulge, and the outer peripheral surface of the second lantern ring is coaxially fixed with a second gear; the first driving device comprises a first motor, and a third gear which can be meshed with the first gear and the second gear respectively is arranged at the output end of the first motor. When the gear III of the motor I is meshed with the gear I, the cantilever I can be driven to swing; when the gear III of the motor I is meshed with the gear II, the cantilever II can be driven to swing, so that the positions of the cantilever I and the cantilever II can be adjusted, and finally, the distribution adjustment of the underwater culture cage can be realized.

In the culture unit in the marine culture system, a concave cavity is formed in the upper plate surface of the circular floating plate, a lifting platform is fixed in the concave cavity, and the first motor is fixed on the lifting platform. After the lifting platform is designed, the first gear can be meshed with the first gear or the second gear by driving the first motor to lift.
