Description

Large-scale shallow sea seining cultivation device
Technical field
The present invention relates to the large-scale breeding facility in a kind of technical field of aquaculture, particularly a kind of large-scale shallow sea seining cultivation device.
Background technology
Mariculture is different from freshwater lake cultivation, and it can be subject to the restriction of the many factors such as ocean, weather, fluctuation tide, so have extremely important status based on the exploitation of water culture facilities.Current sea farming mainly concentrates on cage culture, raft culture and seining cultivation, wherein the extensive seining cultivation in shallow sea is the expansion of traditional offshore beach seining cultivation to off-lying sea deep water sea area, but structurally there were significant differences with traditional offshore beach purse seine engineering, it is one of important form of following marine facility cultivation.
Be existing large-scale shallow sea seining cultivation device as shown in Figure 1, in its structure, the upper edge of purse seine etting 1 is connected with a float layer, thus allowing the upper edge of purse seine etting 1 be not less than sea level, the height that this float floor height goes out sea level can prevent again the cultivation object in purse seine from escaping effectively.But, consider on sea many with wind and waves (particularly typhoon season), the overall percussion by stormy waves and trend of purse seine etting 1 affects and produces resistance, the situations such as easy generation is biased, lifting, float layer is subject to hawser 6 pulling force and immerses in seawater in the above cases, make the float layer of originally bubbling through the water column lose the effect of anti-escape, finally cause cultivation object to be escaped.In order to solve the problem, currently used unique method is the float volume in increase float layer simply, overcomes the lower pulling force that hawser produces float layer, thus avoid in float layer immersion seawater by promoting float buoyancy.But the positional stability extreme difference of float under sea wind effect in said method after volume increase, usually occurs that Culture pure seine, by situations such as high wind blow off, brings serious economic loss to raiser when the bad weathers such as typhoon appear in marine site operating mode.Meanwhile, purse seine etting entirety is subject to the effect of stormy waves and trend and produces resistance, requires that water-bed anchor or stake and anchor system must possess sufficient tension stress, so just can bear the resistance of purse seine etting.But, the anchor architecture of above-mentioned medium-and-large-sized shallow sea seining cultivation device is that each water-bed anchor or stake are all connected with the headline in float layer simply by single hawser, when purse seine etting is overall produce on the direction of stormy waves and trend impact forces biased, thus when impelling hawser to be in tight state, the one direction load that each water-bed anchor or stake are born is comparatively large, easily occurs running the damage such as anchor, de-stake situation.Therefore, be necessary to do further technological improvement to the structure of above-mentioned existing large-scale shallow sea seining cultivation device.
Summary of the invention
The object of the invention is to provide a kind of possess the reliably anti-large-scale shallow sea seining cultivation device escaping structure and wind wave resistance anchor architecture to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, one designed by the present invention large-scale shallow sea seining cultivation device, comprise stake or anchor that purse seine etting and uniform ring are located at this purse seine etting border, the upper port of described purse seine etting is connected with the first float layer along place, described stake or anchor are connected with the first float layer by hawser, also be provided with etting extension above the first described float layer, the Single port of this etting extension docks with the first float layer, and its edge, another port is connected with the second float layer.
Above-mentioned one large-scale shallow sea seining cultivation device, has set up again the second float layer in its structure above the first float layer, is docked by the first above-mentioned float layer by the etting extension necessarily designing width with the second float layer.Therefore the seining cultivation device of said structure is carried out cultivation operation at the shallow sea area preset, when marine site operating mode is in tranquility (purse seine etting is not subject to high sea and trend percussion affects), the first float layer in its structure and the second float layer all across the sea floating, and there is certain height the first float layer and the second equal above tide of float layer, can play effective anti-escape effect; When marine site operating mode is in badness (purse seine etting is subject to high sea and trend percussion to be affected and the situations such as biased, lifting occur), the first float layer now in its structure is subject to hawser pull and is dipped in seawater, but owing to having additional etting extension between the second float layer and the first float layer, and the connected node of hawser is not arranged on the second float layer yet, therefore the second float layer still can swim on sea level, thus plays the effect of anti-escape.
In above-mentioned, the bore of the second float layer is preferably less than the bore of the first float layer.When the seining cultivation device of said structure works in the operating mode of severe marine site, be subject to hawser pull when the first float layer and be dipped in seawater, second float layer will form a reducing shape relative to the first float layer, advantageously in preventing the cultivation object in purse seine etting from escaping.
As further technology is preferred, the first float layer in above-mentioned and the concrete connected mode of stake or anchor are: described each stake or anchor are all connected with two hawsers, the other end of these two hawsers to be all connected on the first float layer and to form two connected nodes, form an intervening gaps between these two connected nodes, the connected node of two adjacent hawsers on the first float layer simultaneously on adjacent two or anchor coincides.Because each stake or anchor are all connected with the first float layer by two hawsers in above-mentioned further Technological improvement plan, and have the spacing distance of setting between two connected nodes formed on the first float layer, two hawsers are on the whole in " eight " shape.Therefore, when purse seine etting is overall occur on the direction of stormy waves and trend impact forces biased, thus when impelling hawser to be in tight state, each anchor or stake can bear two relatively uniform active forces in different directions, avoid occurring that stake or the excessive situation of anchor one direction load occur; And the connected node of two adjacent hawsers on the first float layer on adjacent two or anchor coincides again, make each connected node that the first float layer is formed can bear two relatively uniform active forces equally in different directions, Culture pure seine is overall under stormy waves and trend percussion, these two active forces pin down mutually, thus the relative maintenance promoting Culture pure seine integral position is stablized; Meanwhile, above-mentioned anchor architecture can also reduce the quantity of stake or anchor, decreases the working feature in assembling, reduces the operational risk of workmen.
As further technological improvement, on each above-mentioned root hawser, the position of distance first float layer 2m all has additional ball float, and the position of distance stake or anchor 2m has additional sinker.On each the root hawser apart from float layer 2m, assemble a ball float in above-mentioned improvement opportunity scheme, make the hawser of this section of 2m float on sea with ball float; Apart from an assembling sinker on every root hawser of stake or anchor 2m, this section of hawser between sinker and stake or anchor is made to press close to seabed.So impacting when stormy waves and trend acts on Culture pure seine, when ball float does not sink to marine, the hawser floated on the water surface will reduce the float power that pulls straight down, simultaneously by the effect of sinker, the power that weighs anchor straight up acted on stake or anchor also reduces, thus alleviate the stake in seabed portion or the load burden of anchor, so ball float and sinker all play cushioning effect to Culture pure seine, alleviate the load burden of whole seining cultivation device under stormy waves and trend percussion.
Compared with prior art, thus advantage of the present invention makes Culture pure seine device more firmly stable under stormy waves and trend impact, alleviate the load burden that device is subject to, meanwhile, novel anti-structure of escaping also can play when marine site operating mode is in badness and effectively anti-ly escapes effect.By above-mentioned 2 improvement, thus ensure the fanning economics of raiser to the full extent.
