Summary of the invention

Broadcast and be difficult to hide, resist fish, shrimp, these harmful animals of crab in order to overcome the individual little direct end of sea cucumber seedlings, survival rate less than 20%, is that ecosystem sea cucumber seedlings kind is found " family " supported temporarily.The utility model provides a kind of raft body, cylinder mould mesh bag etc. of the buoyant raft that utilizes existing cultivated shellfish to cultivate the seabed of utensil below the shellfish culture buoyant raft device of foster sea cucumber seedlings temporarily.

The ecological foster technical scheme temporarily of sea cucumber seedlings that the utility model provides is: the plastic tube of supporting temporarily cylinder mould bamboo pole or sealing of shellfish culture is propped up, the plastic tube of bamboo pole or sealing can produce buoyancy in seawater, by hang with the mesh bag of sea cucumber seedlings or net on chip enter mesh be only less than in the mesh bag of sea cucumber seedlings, again mesh bag is packed into supporting temporarily in cylinder mould and put float in cylinder mould of shellfish culture, connect sandbag at cylinder mould two ends with connection cord, one end of cylinder mould connects to form a device by lifting rope and raft body, this device is done the reciprocating motion of two horizontal directions every day in seabed according to the variation of trend with raft body, in the time there is no trend, cylinder mould can keep with seabed the distance of 0.3 meter-0.5 meter, greatly the impulsive force of cylinder mould horizontal direction is produced much larger than cylinder mould in tidal current speed total buoyancy time, the distance in cylinder mould and seabed can diminish, can make cylinder mould more be close to seabed, silt has more chance and enters cylinder mould, and on mesh bag or net sheet, adhere to and provide sufficient nutriment for sea cucumber seedlings.

The beneficial effects of the utility model are: fill up the marine ecological breeding of sea cucumber net cage and sea cucumber seabed ecology and form middle technological gap, sea cucumber seabed ecology is formed a complete industry chain (supply chain) to make the marine ecological breeding of its formation sea cucumber net cage---sea cucumber seedlings cylinder mould seabed is ecological supports temporarily---, improve the stress of cylinder mould by the combination of buoyancy and trend impulsive force, alleviate the frictional force in cylinder mould and seabed, prevent the breakage that cylinder mould causes in the silt friction process of seabed.

Accompanying drawing explanation

Fig. 1-1 and Fig. 1-2 are that sea cucumber seedlings is supported schematic diagram of device temporarily.(1) be that cylinder mould, (2) are that float, (3) are that bamboo pole (plastic tube), (4) are that raft body, (5) are that connection cord, (6) are that lifting rope, (7) are sandbags.The position in A, expression seabed.

Fig. 1-1 represents that the less or tidal current speed of tidal current speed levels off at 1 o'clock, the state of cylinder mould.

When Fig. 1-2 represents that tidal current speed is larger, the state of cylinder mould.

Fig. 2 is net cage separator figure, is on common net cage separator, to process 1 actinomorphic cavity take circular hole as main body.

Embodiment

Utilize the cylinder mould of mesh at the common temporary shellfish culture of 0.5-0.8 centimetre, at a circular hole of its net cage separator central authorities processing, circular has multiple length to equate to be uniformly distributed gap, the actinomorphic cavity of composition take circular hole as main body.Diameter is greater than to the bamboo pole of circular hole in the middle of cylinder mould or the plastic tube of sealing to be passed from the circular hole of each net cage separator central authorities successively, and by stretching cylinder mould to long status, the automatic banding bamboo pole of elasticity or plastic tube that circular hole in the middle of each net cage separator can utilize plastics itself to have, make cylinder mould keep propping up state.Entered before the winter, the mesh bag or the net sheet that hang with sea cucumber seedlings are taken out from net cage, pack in the mesh bag that mesh is only less than sea cucumber seedlings and after mesh bag mouth being tightened with cotton rope and pack in described cylinder mould, every layer of dividing plate fills 40 left and right sea cucumber seedlings and is advisable, then empty mineral water bottle or the cursory buoyancy that cylinder mould entirety can be produced more than 2 kilograms in seawater of plastics of inwardly respectively putting two sealings in several the 3rd or the 4th layer of dividing plate at cylinder mould two are advisable, and cylinder mould are sewed up with sealing line.One end of cylinder mould is connected with raft body with lifting rope, connects sandbag by connection cord at cylinder mould two ends, the gross weight of its sandbag is advisable with the buoyancy that is enough to overcome more than 2 kilograms in seawater, and the length of lifting rope and connection cord is 0.3 meter-0.5 meter.These are all the needed nutriments of sea cucumber in the silt in the seabed of original cultivated shellfish, to deposit the organic matter such as excreta of various rot halobiontic corpse chips, shell fragment, cultivated shellfishes and bacterium.In tidal current speed, less or tidal current speed levels off to 1 o'clock this device, the buoyancy and the seabed that produce by the float in cylinder mould maintain a certain distance as Fig. 1-1, larger in tidal current speed, the horizontal direction impulsive force of trend is during much larger than buoyancy, the distance in cylinder mould and seabed can diminish and even can make cylinder mould press close to seabed as Fig. 1-2, in this process, silt always has an opportunity to enter cylinder mould and adhere on mesh bag, this device is done the reciprocating motion of two horizontal directions every day in seabed according to the variation of trend with raft body, the large-area nutriment obtaining in silt provides convenience in seabed to give sea cucumber seedlings.Spring next year is when sea cucumber seedlings grows to while being greater than the mesh of cylinder mould, then mesh bag mouth is opened cylinder mould is sewed up, in statu quo put back to seabed, 6 the end of month, more than 65% sea cucumber seedlings can grow to 200 per jin, individuality meets the end and broadcasts requirement and can be directly used in seabed ecology and form, remaining sea cucumber seedlings that 35% individuality is less can continue to support temporarily and carried out the end before the winter again and broadcast ecology and form, this technical scheme has been filled up the marine ecological breeding of sea cucumber net cage and sea cucumber seabed ecology is formed middle technological gap, makes ecological culture of sea cucumber form a complete industry chain (supply chain).
