A plurality of circular holes with the same size are uniformly distributed at the position, close to an inner frame ring, of each square frame type net cage supporting plate, and the square cylinder type netting and the circular holes are sewed to form a net cage opening at the two ends. Four uniformly-distributed circular holes are formed in the four corners of each square net cage supporting plate, a plurality of gaps with the same length are uniformly distributed at the peripheries of the circular holes, so that radiating cavities with the circular holes as main bodies are formed, four bamboo poles with the diameters slightly larger than the diameters of the circular holes or the sealing plastic pipes similar to the rod-shaped bodies penetrate through the circular holes in the square frame type net cage supporting plates in sequence respectively, the net cage is straightened to be in the longest state, and the circular holes in each square frame type net cage supporting plate can automatically hoop the bamboo poles or the sealing plastic pipes similar to the rod-shaped bodies by using the elasticity of the plastic bodies to form the square frame type net cage.

Description

A kind of square framework type holothruian cultures cylinder mould

Technical field

The present invention relates to fishery holothruian cultures, is utilize the raft of buoyant raft in a kind of square framework type cylinder mould of bottom culture sea cucumber.

Technical background

The new technology of the marine sea cucumber ecology nursery of current a kind of net cage is surging forward in Changhai County, Liaoning Province, and the new technology of seabed cylinder mould culturing sea cucumbers is also arisen at the historic moment, and its know-why is the natural law utilizing trend to change the direction of motion and size twice daily.Trend impacts cylinder mould makes it realize the reciprocating motion of two horizontal directions every day in seabed, and the large-area acquisition of sea cucumber can be made to be deposited on the various nutriments in seabed.The reciprocating motion of cylinder mould can prevent it from being sticked by silt.

But in silt seabed or husky mud seabed not through transformation, connects with cylinder mould in the industrialized development process of raft body foster sea cucumber temporarily that there are the following problems.

1, wire mesh cage structures is unreasonable.Be all the cylinder mould adopting cultivated shellfish at present at the cylinder mould of bottom culture sea cucumber, this cylinder mould is by hanging culture design, and net cage separator is not only disc is etting supporter but also be cultivated shellfish weight body.In order to cultivate more shellfish in unit of water body, distance between dividing plate is very little, general all in 120 millimeter, and cylinder mould is horizontal positioned in the process of bottom culture sea cucumber, net cage separator not load-bearing only works to support etting does not need so much intensive dividing plate.Sea cucumber needs the adherance of software in cylinder mould, is all generally to utilize the mesh bag that uses in net cage seedling nursery process and mesh sheet to make adherance, directly the mesh bag and mesh sheet that are attached with sea cucumber seedlings is taken out from net cage and is put in cylinder mould.Adherance is always deposited in the bottom of cylinder mould circular arc, has the space of more than 2/3rds not to be utilized effectively above adherance.Adherance cannot be worn bunchiness as net cage seedling nursery because net cage separator is disc dividing plate and hang in the seawater with not communicating between dividing plate.

2, in seabed, the long-time and barrier such as silt, shell friction is easy to breakage to cylinder mould, causes sea cucumber to escape

Ease.

3, the connected mode of cylinder mould and raft body is unreasonable.One end of cylinder mould is connected with raft body, and cause cylinder mould axially along direction of tide, effective lifting surface area that cylinder mould itself accepts trend impulsive force is less, and especially in the time period that dead flood season, trend diminished, cylinder mould is difficult to the reciprocating motion realizing making horizontal direction in seabed.The scope causing sea cucumber to obtain nutriment on the one hand reduces, and cylinder mould is easy to be sticked by silt on the other hand.

In order to overcome above-mentioned three subject matters, the invention provides a kind of square framework type cylinder mould and can make full use of the penetrating solid space of cylinder mould, and the etting breakage that cylinder mould can be avoided directly to cause with silt contact friction, adopt a kind of new mode that this square frame style cage is connected the impulsive force that can make full use of trend with raft body and prevent it from being sticked by seabed silt.

The present invention's adopted technical scheme of dealing with problems is: form netpen framework by square frame-shaped cylinder mould gripper shoe and the similar rhabodoid such as bamboo pole or plastic tube.Square frame-shaped cylinder mould gripper shoe inside casing seam square tube shape etting, composition square framework type cylinder mould.Cylinder mould inner chamber is equipped with and floats base curtain, is connected at cylinder mould two ends with raft body, and raft is equipped with the device that sandbag forms a kind of square framework type cylinder mould bottom culture sea cucumber with it.

The invention has the beneficial effects as follows: the production cost reducing cylinder mould, makes full use of cylinder mould space.

Embodiment

Square framework type cylinder mould gripper shoe is injection molded into injection molding machine of plastic is disposable, this square frame style cage gripper shoe has near inside casing place and is multiplely uniformly distributed the equal-sized circular hole for sewing up square tube formula etting, multiple square framework type cylinder mould gripper shoe is equidistantly formed together with square tube formula joining the square framework type cylinder mould of a both ends open formula.

There are 4 circular holes at square framework type cylinder mould gripper shoe 4 jiaos of places, circular has the equal equally distributed gap of multiple length, the actinomorphic cavity of composition based on circular hole, during use, the similar rhabodoid such as bamboo pole or plastic tube of 4 diameters slightly larger than circular hole is passed successively from the circular hole multiple square framework type cylinder mould gripper shoe respectively, and by stretching for cylinder mould to most long status, the rhabodoid composition square framework type cylinder mould that the elasticity automatic banding bamboo pole that the circular hole in each square framework type cylinder mould gripper shoe can utilize plastics itself to have or plastic tube etc. are similar.

Mesh bag and mesh sheet cotton rope are tied up composition on bamboo pole and float base curtain, to float in base curtain loading square framework type cylinder mould, bamboo pole can produce buoyancy in the seawater makes it automatically be close to the top of square framework type cylinder mould, in the seawater that adherance curtain can be made to be suspended in square framework type cylinder mould.

Tightened up by the etting line rope that the frame-type cylinder mould two ends of floating base curtain and sea cucumber are housed, and be connected with raft body, the length of its connection cord is advisable slightly larger than 1/2 square framework type cylinder mould gripper shoe.Raft between each square framework type cylinder mould fixes sandbag with it, its weight 2-3 kilogram.Lay down the buoyant spheres on buoyant raft, stay if desired a buoyant spheres as its buoyancy rope of mark length slightly larger than full towards time sea to the distance in seabed, raft body is together sunk to seabed together with square framework type cylinder mould, raft can press close to seabed under sandbag Action of Gravity Field, and square tube shape etting on square framework type cylinder mould maintains a certain distance with seabed all the time owing to there being square framework type cylinder mould gripper shoe to support, can effectively prevent the etting that causes with the barrier friction such as seabed silt or shell damaged.Frame-type cylinder mould realizes two horizontal directions every day together with raft body under the impact of trend reciprocating motion in seabed can effectively prevent square framework type cylinder mould from being sticked by silt.With dead man, the lifting of raft body can be carried out to ship limit when results or intermediate detection.
