Abstract
The invention discloses a mounting method of a large shallow sea purse net cultivation device. The mounting method is characterized by comprising the following steps of firstly assembling the purse net cultivation device on the coast, and secondly binding multiple separately distributed connection ropes between a floater layer and a sinker, so that an initial interval between the floater layer and the sinker is smaller than the depth of the water level of a mounting point of the cultivation device at rising tide; when the cultivation device floats along with the tidewater after rising tide, pulling the cultivation device into a cultivation site by a boat, untying connection ends of the connection ropes and the floater layer to enable the sinker to naturally sink into the seabed at the cultivation site, fixing the connection ropes with a pile or an anchor at the seabed, finally connecting multiple anchors onto the floater layer, and sinking the anchors down to the seabed to finish the mounting. The mounting method of the large shallow sea purse net cultivation device has the advantages that the large shallow sea purse net cultivation device can be easily mounted at the cultivation site, and the mounting and fixation are easier and more convenient.
Description
Technical field
The present invention relates to large-scale shallow sea seining cultivation, relate in particular 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 the exploitation based on water culture facilities has extremely important status.Sea farming at present mainly concentrates on cage culture, raft culture and seining cultivation, wherein the extensive seining cultivation in shallow sea is that traditional offshore beach seining cultivation is to the expansion of 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 generally consists of etting, sinker, float, stake or anchor and auxiliary equipment thereof etc., whole device volume is huge, in order to guarantee that purse seine device can not get out from net bottom, purse seine device generally will be with every meter heavy 30 kilograms above iron chains as sinker, whole system weight is very large, makes purse seine device in the sea, install and fix very difficult.At present, purse seine device is generally after a nautical mile segmentation is laid, and diver sews up each section of etting under water again, and workload is large, long construction period, and be difficult to guarantee the suture quality of etting.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of installation method of installing and fixing 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 seining cultivation device of required installation 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, to this cultivator, specifically adopts following steps to install:
(1), first by the sea float layer, etting and sinker are assembled into seining cultivation device, then between float layer and sinker, bind many and be connection cord spaced apart, one end of connection cord and the binding of float layer, the other end of connection cord and sinker binding, 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 being connected the cultivator that ties up of rope and floating 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 that the stake in connection cord and seabed or anchoring is fixed;
(4), on float layer, connect a plurality of anchors, and anchor is sunk to seabed, complete the installation of whole cultivator.
In step (2) before, when tying up after cultivator with connection cord, on float layer, be fixedly connected with a plurality of ball floats, to guarantee that cultivator when the high tide, can float 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 two perpendicular guiding principles on described etting, to guarantee that etting is can be stressed too large and do not pulled open.
Compared with prior art, advantage of the present invention is large-scale shallow sea seining cultivation device can be installed to like a cork to the place that needs cultivation by this method, and installs and fix also more easy and convenient; In addition, cultivator arrives after breeding-ground, and connection cord and anchor or stake are fixing, and on float layer, connect anchor simultaneously, have guaranteed that whole cultivator can not move with wave or sea wind, makes the installation firm stable of cultivator.
Accompanying drawing explanation
Fig. 1 is for passing through the view of the mounted cultivator of this method;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
