Description

A kind of controllable aqueous layer raft type cultivation system

Technical field

The utility model relates to a kind of controllable aqueous layer raft type cultivation system, belongs to the aquatic product culture apparatus field.

Background technology

Raft culture is made significant contribution for China's mariculture, is one of main mode of China's mariculture.Though the raft culture scale of China occupies first place in the world, culture kind and relate to algae (sea-tangle, laver, asparagus, Eucheuma, agar, Sargassum fusiforme (Harv.) Setch), shellfish (scallop, oyster, mussel), Bao, ginseng, sea urchin, tens kinds of crab classes etc., cultured output accounts for the over half of domestic mariculture gross yield, per unit area yield has also reached higher level, but the mariculture activity major part of China concentrates on offshore-15 meter isobath with shallow waters at present, waters between-15～-40 meters isobaths still remains to be developed energetically, stream is anxious but because the wave is high in these marine sites, be difficult for setting up the raft culture equipment, therefore be badly in need of carrying out the wind wave resistance technical research of high sea situation waters raft culture facility, expand new breed space, satisfy great demand the sea fishery healthy and sustainable development.The Eleventh Five-Year Plan period; country has given abundant attention to raft culture job facilities and ecologic breeding technology; project verification major project problem; how tame colleges and universities and scientific research institutions' cooperation powerful in the United Nations are tackled key problems; at the marine site ecological characteristic; with the shellfish algae is the main object of culturing, and research raft culture job facilities structure and layout optimization technique, wind wave resistance technology, large-scale ecological control technique make up the efficient raft culture job facilities system of suitable high sea situation operation.

Summary of the invention

Originally put forward utility model for a kind of controllable aqueous layer raft type cultivation system, by the power of drifting along and the buoyant rope length in the control raft formula system, realize the descending operation of raft culture system, solved the wind wave resistance poor performance and the problem that can not regulate and control water layer arbitrarily of existing deep water raft culture facility.

A kind of controllable aqueous layer raft type cultivation system, by well rope rope (1), balance ball float string (2), anchor line (4), fixing ball float (5), water layer regulation and control ball float (6), degree of depth regulation and control ropes (7), pouring weight (8), piled anchor (9) is formed, well rope rope (1) is main rope, length can reach 40m～100m, culturing object (3) hangs on the well rope rope (1), balance ball float string (2) is a string little float, rope series connection by the about 8mm of diameter, evenly tie on well rope rope (1), be used for balance and culture most of weight of object (3), water layer control ball float (6) is tied respectively in the two ends and the middle part of well rope rope (1) by degree of depth regulation and control ropes (7), if well rope rope (1) more in short-term, only need to be provided with at two ends, pouring weight (8) is tied in well rope rope (1) position of each water layer control ball float correspondence, is used for effectively realizing the sinking of well rope rope (1), and fixedly ball float (5) and even restrict (10) are arranged in the appropriate location that anchor line (4) is held on the upper side, this node one end links to each other with well rope rope (1), and the other end is connected with piled anchor (9).

The utility model adopts the submerged depth of degree of depth regulation and control rope control well rope rope, not only helps improving the raft formula system wind wave resistance performance under the typhoon weather, and can adapt to the different breeding object to culturing the requirement of water layer.The utility model processing technology is simple, and operation is convenient, and long service life is convenient to large-scale popularization, has well adapted to the demand that facility cultivation advances to the off-lying sea.

Embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.

As shown in Figures 1 and 2, a kind of controllable aqueous layer raft type cultivation system, well rope rope (1) is a polyethylene rope, long 40m～100m, two ends link to each other with piled anchor (9) by anchor line (4), are fixed in to specify to culture the sea area.The upper end of anchor line (4) is apart from water surface certain position place, link to each other with fixing ball float (5) by connecting rope (10), the length that connects rope (10) needs the depth capacity of dive to decide on well rope rope (1), according to actual sea situation wave condition, can select in 2.0m ~ 4.0m scope, the maximum diving depth of well rope rope (1) can reach 4.0m ~ 8.0m like this.Fixedly the setting of ball float (5) is in order to guarantee that anchor line (4) is in tensioning state all the time, controls the maximum diving depth of well rope rope (1) simultaneously.Culture object (3) and directly tie on well rope rope (1),, go up even hanging balancing ball float string (2) at well rope rope (1) for the weight of balance breed object (3).Culture object (3) weightening finish gradually, so in breeding process, the buoyancy that needs continuous adjustment ball float string (2) to provide.Have two kinds of methods to realize: the one, whole balance ball float string (2) to be changed, balance ball float string (2) is connected suitably big or small float by rope, carries out integral replacing then; The 2nd, according to the growing state of culturing object (3), constantly increase the quantity of little float.In order to realize any control of well rope rope (1) submerged depth, be connected water layer regulation and control ball float (6) by degree of depth regulation and control ropes (7) respectively with the middle part at the two ends of well rope rope (1).Because most of weight of breed object (3) is balanced ball float string (2) and offsets, therefore for realizing stable sinking, tie weight (8) respectively in degree of depth regulation and control rope (7) bottom, the submerged depth of well rope rope (1) can be controlled by the length of adjusting degree of depth regulation and control ropes (7).

In the such scheme, each rope can adopt the polyethylene material, and its diameter is decided on the breed scale, and the diameter of general well rope rope (1) and anchor line (4) should be suitably big.Various ball floats or float can adopt materials such as plastics ball float, glass ball float or foam ball float.Though illustrate and describe by the reference preferred examples, those skilled in the art should understand, and in the scope of claims, can do the various variations on form and the details.
