Description

Method of connecting fishing net

The present invention relates to fish with floating the support guiding principle of gill net and set net and the coupling method of mesh.

As everyone knows, old-fashioned fishing net, set net as shown in Figure 10 is such, sagging from the sea, and, rub moment or lower pulling force so net is subjected to huge wave across the sea by wishing expansion, fishing net is split away off from the fishing guiding principle, in addition, when net unfolding, must be connected to net on the thick support guiding principle every a determining deviation.

Because there are the problems referred to above in old-fashioned fishing net, require a kind of rational labour-saving method of connecting fishing net that meets following requirement of invention in worldwide: (1) exempts the trouble that net is loaded onto, pulled down, (2) use a kind of coupling method that does not have ligation, and can not cause coming off of fishing net, (3) make action required place and operating time minimum.

When adopting uneconomic coupling method in the past, just the main guiding principle R that has float is connected with middle guiding principle R ' at a certain distance, knit one by one oval or half elliptic tubercle R with other cord then ", gradually the horizontal side-hung of fishing net on main guiding principle R; And the woollen yarn knitting expense of fishing net superior thyroid tubercle is very high.For do not need with main guiding principle R float gill net (not expressing among the figure) situation too, also very uneconomical.

The object of the present invention is to provide above-mentioned all shortcomings of a kind of energy elimination to be convenient to the connecting method of implementing again.

Introduce the inventive method and use-case below in detail.Fig. 1, Fig. 2 and Fig. 3 represent the structure of fishing guiding principle R of the present invention respectively, wherein each strand and a circular fine rule S(high-tensile strength litzendraht wire) to knit together, circular fine rule also from supporting guiding principle R sagging, forms many ears.

When this special-purpose fishing net R of automatic braiding is arranged, make the sagging length 1 of an ear S, equate substantially with spacing L between this ear S and next the ear S or long slightly, so below fishing net, form a series of same ears.

Float gill net in actual use and can use the special-purpose fishing guiding principle R(diameter of various thicknesses from 3 millimeters to 50 millimeters), select arbitrarily below diameter be 7 millimeters support guiding principle R as an example.In 8 strands of softness braiding, enrolled fine rule S(Fig. 2 of 3 millimeters of one diameters), the sagging length 1 of ear ₁And the distance L between two ears equates substantially, is of a size of 25 centimetres or 30 centimetres.

Following in order to play a part, the termination 1 of any ear S is inserted and passed along expansion direction in the tissue of guiding principle R, pass (referring to Fig. 3) after the heat downwards, form sagging length and be 1 the little ear E of hollow; By mode shown in Figure 4 the long ear S of the next one is packed into above-mentioned little ear E then; In order to enable to become a kind of easy coupling method (its effect will be introduced in the back), must make stipulations to above-mentioned size in advance.In order to improve the expansion power and the connection power of net greatly, can take apart easily again simultaneously, among Fig. 31 ₂And L ₂Relation also with above-mentioned identical, even the sagging length 1 of the little ear E that forms ₂Equal L substantially _fIn this example, get 1 ₂=L ₂=2.6 centimetres is suitable.

As above said, under employing situation of the present invention, only make and form sagging ear S, S, the S that many length 1 equate on the special-purpose fishing guiding principle R simply ... though shown in fishing net material how, its manufacturing cost with do not have much difference in the past, can produce in enormous quantities.

Introduce the coupling method (referring to Fig. 5) in the fishing net evolutionary operation below.The termination 1(figure that is used for clamping the ear S of starting point does not express) penetrate the suitable (not shown) of threading a needle, with threading a needle above-mentioned termination 1 is penetrated fishing guiding principle R then, expansion direction at interval the starting point 2 of L ' near (downside of fishing guiding principle) pass the fishing guiding principle.

Can be modified to little ear E(to ledge referring to Fig. 5 at an easy rate).This moment can be with directly perceived or measure and make l ₂And L ₂Equate substantially.

Then in a manner described next ear S is inserted in the circle of above-mentioned little ear E (referring to Fig. 4); Before this ear S is firmly strained along X direction, the commissural flange of fishing net N (Fig. 6) is worn on the horizontal expansion direction that is suspended to this ear very simply.

Every like this tension one section just advances 25 centimetres (L) substantially, forms a little ear E(at a 3 ' place, referring to Fig. 5 by above-mentioned the same manner then), and pack into next ear S ' again.

Under the situation that adopts method of connecting fishing net of the present invention, the main ear S of ring-type, S, S ... each fixedly hang down a little 2,3,4,5 ... the little ear E of (see figure 6) and relevant position, E, E variable hang down a little 2 ', 3 ' ... (see figure 5) coincides together when each ear S laterally strains, thereby can improve the service life of expansion power and fishing guiding principle R greatly.

Reality is used proof: (composition is polypropylene when the support guiding principle that floats gill net, 8 strands) diameter be 7 millimeters, mean depth of water is 10 meters, when the length of run of net is 50 meters, net is 11.3 kilograms in marine gross weight, as not using float, then the intensity of guiding principle and expansion power are 1.240 kilograms (using the measuring method of stipulating in the Japanese Industrial Standards).

By the present invention each ear S is being passed the fishing net hole and mentioning tensioning and when fishing net is launched, below fishing net, just formed a series of tools

inarticulate protuberance

6,6,6 at regular intervals ... (Fig. 7), thus can further improve the intensity of above-mentioned fishing net.

Because like this, the diameter of fishing guiding principle at least can be thinner by 1/5th than in the past, makes the connection operation of fishing net greatly laborsaving.

In the time will repairing or change fishing net, the little ear E(of least significant end is seen Fig. 8) extract out, take apart by opposite sequence then, net N can be pulled down soon.

The connection of fishing net bottom surface and take apart also can be to adopt said method.

Said method was all tested in the sea of Japan and pacific rim; In test, the size of floating the online used float (not shown) of thorn is according to custom and fixed by depth of water size (2 meters～1,000 meter).

Test to set net is to carry out in the marine site of 12 meters of the depth of waters, and the length of run of net is 20 meters.Main in the case guiding principle R(sees Figure 10) diameter is 15 millimeters, and needs with 20 millimeters in the past, promptly only is equivalent to originally 3/4ths, this has just confirmed above-mentioned effect.

Confirm in above-mentioned every test: the mounting or dismounting required time of the fishing net of same length is different and different with the operation place, but average about 1/20th of the required time in the past that only needs.

Under above-mentioned use situation of the present invention, often form

inarticulate protuberance

6,6,6 ... and with the tensioning form (see figure 8) of parallel each the ear S of fishing net, support guiding principle just to present special outward appearance like this.

Below each figure is done simple declaration.
