Description

A kind of cylinder mould of the ecological foster sea cucumber seedlings temporarily in seabed
Technical field
The present invention relates to fishery holothruian cultures, is the cylinder mould utilizing the raft of buoyant raft to support sea cucumber seedlings temporarily in seabed.
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, cylinder mould ecological new technology of supporting sea cucumber seedlings temporarily in seabed is also operated and gives birth to, 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, the large-area acquisition of sea cucumber seedlings can be made to be deposited on stained things such as the various halobiontic corpse in seabed is brokenly cut, the excreta of shell fragment and cultivated shellfish, these stained things are all the nutriments required for sea cucumber.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 seedlings temporarily that there are the following problems.
1, wire mesh cage structures is unreasonable.The cylinder mould of supporting sea cucumber at present in seabed is temporarily all the cylinder mould adopting cultivated shellfish.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, the distance between dividing plate is very little, generally all in 120 millimeter.And cylinder mould lies in a horizontal plane in seabed in the process of bottom culture sea cucumber, net cage separator not load-bearing only plays a part to support etting, does not need so 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 escape.
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 the frame-type cylinder mould that the little annular cylinder mould gripper shoe of a kind of use replaces the new shape structure of a lot of net cage separators, the solid space that cylinder mould is penetrating can be made full use of, and the etting breakage that cylinder mould can be avoided directly to cause with silt contact friction, adopt a kind of new mode this cylinder mould to be 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 annular cylinder mould gripper shoe and the rhabodoid such as bamboo pole or plastic tube.The outer circumferential weld cylindrical shape etting of annular cylinder mould gripper shoe, composition frame-type cylinder mould, cylinder mould inner chamber is equipped with and floats base curtain.Be connected with raft body at cylinder mould two ends, raft is equipped with the device that sandbag forms a kind of 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 the solid space of cylinder mould.

Fig. 3 is annular cylinder mould gripper shoe.
Fig. 4 is the structure drawing of device of cylinder mould bottom culture sea cucumber seedlings.
Fig. 5. be float base curtain.
In figure, 1. is drum type brake ettings, and are 2. the similar tubular bodies such as bamboo pole or plastic tube, being 3. annular cylinder mould gripper shoes, is 4. frame-type cylinder moulds, is 5. connection cords, is 6. seabeds, is 7. sandbags, is 8. raft bodies, is 9. mesh bag and mesh sheet.
Embodiment
Annular cylinder mould gripper shoe is injection molded into injection molding machine of plastic is disposable, this annular cylinder mould gripper shoe has near outer shroud place and is multiplely uniformly distributed equal-sized circular hole for sewing up drum type brake etting, multiple annular cylinder mould gripper shoe is equidistantly formed together with drum type brake joining the cylinder mould of a both ends open formula.
Have 3 equally distributed circular holes between annular cylinder mould gripper shoe inner and outer ring, circular has the equal equally distributed gap of multiple length, forms the actinomorphic cavity based on circular hole.During use, the similar rhabodoid such as bamboo pole or plastic tube of 3 diameters slightly larger than circular hole is passed successively from the circular hole multiple annular cylinder mould gripper shoe respectively, and by stretching for cylinder mould to most long status, the rhabodoid composition frame-type cylinder mould that the elasticity automatic banding bamboo pole that the circular hole in each annular 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, will float in base curtain loading frame-type cylinder mould, bamboo pole can produce buoyancy in the seawater makes it automatically be close to the top of cylinder mould, in the seawater that adherance curtain can be made to be suspended in cylinder mould.
Mesh bag and mesh sheet are preferably taken out from net cage, naturally sea cucumber seedlings is floated in mesh bag or in mesh sheet, the quantity of its sea cucumber seedlings is determined according to the Individual Size of sea cucumber seedlings, support 7 months individualities temporarily for the sea cucumber seedlings of per kilogram about 1500 and reach per kilogram 150, on average every cubic decimeter of water body 6-7 sea cucumber seedlings, presses on average every square decimeter of attachment sea cucumber seedlings and calculates the surface area of adherance.
Tightened up by the etting line rope that the frame-type cylinder mould two ends of floating base curtain and sea cucumber seedlings are housed, and be connected with raft body, the length of its connection cord is advisable slightly larger than annular cylinder mould gripper shoe radius.Raft between each frame-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 frame-type cylinder mould.With dead man, the lifting of raft body can be carried out to ship limit when results or intermediate detection.
Raft can press close to seabed under sandbag Action of Gravity Field, and frame-type cylinder mould is owing to there being 1 bamboo pole on the similar rhabodoids such as 3 bamboo poles or sealed plastic pipe and adherance curtain, 4 bamboo poles can produce the buoyancy of about about 2 kilograms, the sea cucumber seedlings temporarily weight of supporting when coming out of steamer for 7 months has just just reached 1.5 kilograms, substantially the gross buoyancy that the similar rhabodoid such as 4 bamboo poles or sealed plastic pipe produces is reached, therefore substantially can maintain a certain distance with seabed at temporary process center posture cylinder mould of supporting, even if press close to seabed also can not produce much pressure to seabed, therefore can effectively prevent the etting that causes with the barrier friction such as seabed silt or shell damaged.
To be equipped with inside frame-type cylinder mould and to float base curtain and take full advantage of cylinder mould space, and frame-type cylinder mould is axially perpendicular to direction of tide, increase effective lifting surface area of frame-type cylinder mould entirety, can more efficientlyly utilize the impulsive force of trend to frame-type cylinder mould to realize its every day makes two horizontal directions reciprocating motion in seabed.More seabed organic matter can be made at the volley to be attached on the adherance in cylinder mould.Create condition for sea cucumber seedlings large-area acquisition seabed nutriment on the one hand, can effectively avoid cylinder mould to be sticked by silt on the other hand.
Sea-bottom deposit below shellfish culture buoyant raft for many years the stained things such as various halobiontic corpse is brokenly cut, the excreta of shell fragment, cultivated shellfish, these stained thing long-term pollution aquaculture sea area very easily cause the generation of various cultivation disaster, but these stained things are the nutriments required for sea cucumber.Therefore the bottom culture sea cucumber below shellfish culture buoyant raft is for many years selected as much as possible, sea cucumber can be impelled to grow fast on the one hand, the effect that benthon is prevented and kill off can also be played on the other hand, sea cucumber licks the food of own wt 1.4 times every day to have result of study to prove, calculates only sea cucumber seedlings support every platform raft (mu) temporarily and can filter or consume the stained thing in seabed 10 tons every year by this.
