Abstract
The invention discloses the installation method of a kind of large-scale shallow sea seining cultivation device, feature first assembles seining cultivation device by the sea, then between float layer and sinker, many are bound in connection cord spaced apart, the initial separation between float layer and sinker is made to be less than cultivator mounting points water level depth at the incoming tide, when then waiting high tide cultivator to float with tidewater, with ship, cultivator is dragged to breeding-ground, untie the link of connection cord and float layer again, sinker is made naturally to sink to the seabed of breeding-ground, and by the stake in connection cord and seabed or anchoring fixed, finally on float layer, connect multiple anchor, and anchor is sunk to seabed, complete installation, advantage large-scale shallow sea seining cultivation device can be installed to like a cork by this method the place needing cultivation, and install and fix also more easy and convenient.
Description
Technical field
The present invention relates to large-scale shallow sea seining cultivation, particularly relate to the installation method of a kind of large-scale shallow sea seining cultivation device.
Background technology
Mariculture is different from freshwater lake cultivation, 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.
Large-scale shallow sea seining cultivation device is generally made up of etting, sinker, float, stake or anchor and auxiliary equipment etc. thereof, whole device volume is huge, in order to ensure that purse seine device can not get out from net bottom, purse seine device generally with the iron chains of every meter heavy more than 30 kilograms as sinker, whole system weight is very large, makes purse seine device carry out installing and fix very difficult in the sea.At present, purse seine device is generally after in the sea, segmentation is laid, and each section of etting is sewed up by diver under water again, and workload is large, long construction period, and is difficult to the suture quality ensureing etting.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of installation method installed and fix easier large-scale shallow sea seining cultivation device.
The present invention solves the problems of the technologies described above adopted technical scheme: the installation method of a kind of large-scale shallow sea seining cultivation device, the required seining cultivation device installed comprises float layer, etting and sinker, the upper end of described etting is fixedly connected with described float layer, described sinker is fixedly connected with the lower end of described etting, specifically adopts following steps to install to this cultivator:
(1), first by the sea float layer, etting and sinker are assembled into seining cultivation device, then between float layer and sinker, many are bound in connection cord spaced apart, one end and the float layer of connection cord are bound, the other end of connection cord and sinker are bound, and make the initial separation between float layer and sinker be less than cultivator mounting points water level depth at the incoming tide;
(2), at high tide, when the cultivator that being connected restricts ties up floats with tidewater, with ship, cultivator is dragged to breeding-ground;
(3), untie the link of connection cord and float layer, make sinker naturally sink to the seabed of breeding-ground, float layer floats on sea, then by the stake in connection cord and seabed or anchoring fixed;
(4), on float layer connect multiple anchor, and anchor is sunk to seabed, complete the installation of whole cultivator.
Before step (2), after tying up cultivator with connection cord, float layer is fixedly connected with multiple ball float, to ensure that cultivator is when high tide, can floats with tidewater smoothly.
In described step (1), the distribution of described connection cord is corresponding with the perpendicular guiding principle on described etting, spacing between two adjacent connection cords is identical with the spacing between the perpendicular guiding principle of two on described etting, to ensure that etting can not be stressed too large and pulled open.
Compared with prior art, advantage of the present invention large-scale shallow sea seining cultivation device can be installed to like a cork by this method the place needing cultivation, and install and fix also more easy and convenient; In addition, cultivator arrives after breeding-ground, and connection cord and anchor or stake are fixed, and float layer connects anchor simultaneously, ensure that whole cultivator can not move with wave or sea wind, make the installation firm stable of cultivator.
