Description

Larger Collection Net {

The present invention relates to a bell-net structure, and more particularly to a bell-net structure in which a polygonal mesh hole is formed by a warp of a polyethylene mono yarn and a weft of a polypropylene yarn, and the weft yarn is made of polypropylene, And each of the polypropylene raw yarns is composed of a plurality of injections to increase the cohesion rate of larvae.

Scaparca subcrenata is a scapharca subcrenata . It lives in the Honshu-Tokyo sub-area of Japan, the Bohai Sea of China, the East China Sea, and the continental coast of China.

New cichlids in Korea are often called eelgrass, and they live mainly in the pearl between 10m depth from the intertidal flat of the continental coast. Spawning occurs mainly around July to October, while spawning period is from late July to late August. The number of individuals scattered at one time is about 250 to 3 million, and the diameter of the eggs is 60 to 70 ㎛.

On the other hand, in Korea, it is mainly cultivated in the tidal flats of Chonnam coast. In July, when the birds begin to lay their eggs, they have a landing on the tidal flats. It will capture the clinging larvae.

Generally, the bell-net uses a polyethylene monosaccharide to form a warp and a warp, thereby forming a mesh having a quadrilateral net hole having a rhombus or square shape. However, in the case of the general netting structure, there is a problem in that the adhesion of the new larval larvae is not efficient and the yield thereof is lowered.

In order to solve this problem, a 'net for capturing a new catch of larvae' (Registered on Apr. 13, 2011, hereinafter referred to as 'prior art document 1') of Korean Utility Model Registration No. 20-0453311 has been proposed.

In the above prior art document 1, it was attempted to increase the adhesion rate of the larval larvae by using wide-width black film yarn as a weft. However, when the larvae were grown and separated from the net, the birds were not easily separated from the net There is a problem that the new cockles are damaged due to a time-consuming inconvenience to work, and there is an additional problem that the returned part of the weft is not easily restrained due to the return part of the weft,

In order to solve the problem of the prior art document 1, Korean Patent Laid-Open Publication No. 10-2015-0020651 discloses a bird's nest catching net (published on Feb. 26, 2015, hereinafter referred to as "prior art document 2" Has been proposed.

In the prior art document 2, a colorless and odorless polyethylene film yarn was selected as the weft yarn, and the width of the yarn was limited to a range of 1 to 4 mm to increase the cohesion rate of the larvae, However, the adhesion of larvae was not high due to the presence of a single strand of the polyethylene filament yarn. Due to the nature of the polyethylene, it was difficult to separate the new strand through the hair, and the polyethylene was vulnerable to tensile force, There was an additional problem that the rate was high.

Disclosure of the Invention The present invention has been made in order to solve the above problems, and it is an object of the present invention to improve the adhesion rate of new larval larvae, to facilitate the separation of new birds through the hair when the larva grows and separate from the net, The structure is stabilized, and the structure is strong enough to withstand the tensile force by the tidal force and the wave force.

In order to accomplish the above object, the present invention provides a bell-type frame structure in which a plurality of polyethylene monosaccharides are spaced apart from one another to form a plurality of slopes 10, each slope 10 having a plurality of circular rings 11 A plurality of weft yarns 20 are formed so as to cross at least a pair of adjacent warp yarns 10 so that the warp yarns 21 are wound around the pair of warp yarns 10, And an end portion of the upper thread portion 21 passes through the circular rings 11 and is disposed along the inclination 10 to form an inclined direction returning portion 22, In which a weft yarn 21 is formed again in a zigzag shape in the oblique direction and a quadrilateral mesh hole is formed by the warp yarns 10 and the weft yarns 20 , The weft yarns (20) are wound on a first weft yarn (20a) composed of polypropylene yarns Wherein the first weft yarn 21a of the first weft yarn 20a is formed so as to traverse an adjacent pair of warp yarns 10 and the second weft yarn 20b The second weft yarn 21b of the weft yarn 20 is formed so as to traverse at least three adjacent warp yarns 10 so that the weft yarn 21 of the weft yarn 20 is composed of at least three strands of polypropylene yarn, The first oblique direction returning portion 22a of the first weft yarn 20a and the second oblique direction returning portion 22b of the second weft yarn 20b form loops 23a and 23b, And the polypropylene yarns are composed of 40 to 50 yarns which do not mutually twist and behave independently, and each polypropylene yarn is 180 to 240 denier.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 1A and 1B show the construction of a conventional 'bird catching netting net', which is intended to enhance the adhesion rate of bird catching larvae using a film yarn as a weft. However, when the larvae were grown and separated from the net, the new claws did not easily fall off the net, resulting in a time-consuming disconnection of the claws. In some cases, the new claws were damaged.

In addition, due to the nature of the polyethylene used as warp and weft, there is a problem in that it is difficult to separate the birds through the weft, and the polyethylene has an additional problem that the net damage rate due to the flow rate is high due to the weak tensile force.

Hereinafter, the 'weft' in the present invention is defined to refer to a direction parallel to a pillar installed to install a bell tower, and 'slope' is defined to refer to a direction parallel to a longitudinal direction extending horizontally of the bell tower .

2, a plurality of polyethylene monosaccharides are spaced apart from one another to form a plurality of slopes 10, each slope 10 having a plurality of circularly arranged 11 are formed. At this time, the circular ring 11 is formed by continuously twisting one polyethylene monosilicate in a ring shape in the longitudinal direction.

The plurality of polypropylene yarns form a plurality of weft yarns 20 and each weft yarn 20 is provided so as to traverse at least a pair of adjacent warp yarns 10 to form a weft yarn 21, An end portion of the upper thread portion 21 passes through the circular rings 11 and is disposed along the inclination 10 to form the inclined direction return portion 22. [

That is, the turning points of the upper and lower warp yarns 21 and 22 are changed in direction so that a tensile force is concentrated and a strong binding force is required. When the weft yarn 20 passes through the circular yarn 11 of the warp yarns 10 The stability of the structure can be secured.

At this time, a warp yarn 21 is formed again on the end of the warp direction returning portion 22 to form a weft yarn 20 having a continuous zigzag shape in an oblique direction. At this time, the stomach part 21 to be formed again forms a continuous staggered shape by forming the staggered return part 22 in the direction opposite to the adjacent stomach part 21.

Thus, the warp yarns 10 and the weft yarns 20 form a continuous warp net structure in which a continuous tetragonal mesh hole is formed.

As shown in FIG. 4, the polypropylene yarn constituting each weft yarn 20 is composed of a plurality of injections, and the polypropylene yarn is formed into 180 to 240 denier, By increasing the surface area, it is possible to increase the adhesion rate of the larval larvae.

At this time, since each of the polypropylene raw yarns has a plurality of injections acting independently, it is possible to easily separate the bird cockles from each other when the larva is grown and separated from the net.

More specifically, the polypropylene yarn forming the weft yarn 20 may be composed of 40 to 50 yarns, and the yarn denier may be in the range of 180 to 240 deniers depending on the number of yarns constituting one polypropylene yarn .

In general, polyethylene monosaccharide is used for the production of a net including a bell-net, polyethylene has a light and flexible characteristic as a thermoplastic, has a tensile force of 9 g per denier, but has a disadvantage that it is easily damaged or tarnished by strong algae or waves, There is a problem that the tensile force becomes weaker when the film is made into a film.

Polypropylene, on the other hand, is composed of one methyl group bonded to the carbon of the polyethylene molecular chain. It has higher transparency and stronger tensile strength than polyethylene.

Therefore, according to the present invention, by using polypropylene yarn as the weft yarn 20, it is possible to provide a structure that is stable to strong algae or waves, more durable and strong against tensile force, There is an advantage that separation of the cockles is easier.

3, the weft 20 includes a first weft yarn 20a and a second weft yarn 20b each made of polypropylene yarn, and the first weft yarn 20a has a first weft yarn 20a and a second weft yarn 20b. The second weft yarn 21b of the second weft yarn 20b is formed so as to traverse at least three adjacent warp yarns 10 and the second weft yarn 21b of the second weft yarn 20b is formed to cross at least between the adjacent three warp yarns 10, .

That is, a pair of first and second weft yarns 20a and 20b are provided, and the lengths of the first and second weft yarns 21a and 21b are different from each other, (21) may be composed of three strands of polypropylene yarn.

As a result, the surface area of the weft 20 can be increased, the adhesion rate of the larval larvae can be increased, and a more structurally stable tissue can be secured.

3, the first inclined direction returning portion 22a of the first weft 20a and the second inclined direction returning portion 22b of the second weft 20b are connected to the loop 23a, (23b) are formed so that mutual engagement can be formed.

By interlocking the loops 23a and 23b, a stable structure can be formed in spite of a plurality of injections constituting one polypropylene yarn, and there is an additional advantage of being strong against tensions due to a tidal force and a wave force.

The inclined direction returning portion 22 may be disposed along the inclination 10 and may penetrate the plurality of the circular rings 11 of the inclination 10.

As a result, the oblique-direction returning portion 22 can be firmly fixed to the warp yarns 10, so that the returning portion of the weft yarn 20 is easily relaxed by the tidal force and the wave force, .

The present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Therefore, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. It is to be understood that the present invention belongs to the scope of protection of the patent claims to the extent that the invention can be variously modified and implemented.
