Description

[0001] The present invention relates to a fishing net having a fishing force for capturing webfoot octupus,

The present invention relates to a weight body used for fixing a shellfish shellfish, a body weight body having a cross shape on one side and a narrow width on the other side in one direction, and a cross- And the weight of the shell of the shellfish which can reduce the loss of the fishing gear installed in the water by improving the fixing force of the fishing gear connected to the weight.

The shellfish shellfish (aka jukinmi soho) belonging to the coastal compound fishery is one of the words with many loss due to the storm along with the netting, The shellfish shellfish is installed at a relatively shallow water depth of about 15 m, which is relatively shallow compared to other coastal fisheries, and is easily exposed to the influence of waves. In addition, a sand bag ), So that the fishery environment and fishery composition are vulnerable to loss.

Shellfish shellfish refers to the fishery that uses shellfish or high shellfish to lay on the seabed without bait and to catch the creatures contained in the shellfish. The main species of shellfish shellfish are jukumi and octopuses are also seized.

The general structure of the Shellfish Shellfish is composed of a buoy line indicating the position of the fishery, a buoy line connecting the buoy and the fish, a coral line connecting the buoy line and the buoy line horizontally and a shellfish shell attached to the coral line, And the bruises and bruises connected to both ends of the corrugated lines are fixed to the sea floor.

The fishing method of shellfish shellfish fishing is when the fishing boat arrives at the fishing ground, the fishing boat sails at low speed and drops the buoy from the ship and gives out the buoy line. When the row of buoys is over, he bruises and gives off his bruises from the bow of the heavens. Depending on the salivating force of the dropped bruise and the speed of the ship, the bark of the shell begins to fall as the marginal line rises.

At this time, the crews in turn drop shells on the corrugated lines so that the corrugated lines do not get tangled. When the bark of shells with all the corrugated lines are all dropped, the bruises, buoys and buoys are dropped and the tour ends. Shellfish shells are immersed for about 7 days, the time for the target creature, juku, to enter shellfish shells fully.

Anchor is often used to fix a fish to a certain location, but anchor is often expensive and inconvenient to collect after the period of use, so put a stone, gravel, It is called a sand bag.

Bruises are less common in the seabed compared to anchors of the same weight but are used extensively in shellfish shellfish because of the advantage that the anchors do not have a problem of stringing or entangling the anchors. Unlike fishing, which uses anchors such as nettles and pots, the reason for using bruises only in shellfish shells is due to the way they operate. In the case of harvesting and fishing, both the anchors and the anchors are caught in the harvesting of the catches, but the shellfish shells are raised on the deck only by shellfish shells, and the bruises except for the last bruise on the end of the catch are not destroyed.

In order to identify the catch without bruising, the bark must be long enough to prevent the bruise from being pulled up when the shell of the shell is pulled up to the deck. A fishery with a depth of 10 m usually has a length of 30 m. If the anchor is used in a state where the length of the line fixing the fishing gear is long, there is a possibility that the line may be wound around the anchorpost or the anchorpipe.

Bruises, on the other hand, are less likely to be wrapped around their yoke by their simplicity. Therefore, the longer the length of the bruise, the greater the ability to increase the fixation force of the bruise. Therefore, in order to reduce the loss of shellfish shellfish, it is necessary to reduce the force applied to the fish when a strong storm occurs, but it is necessary to improve the fixability of the fundamentally vulnerable bruise.

Studies related to the anchoring force have been reported, but studies related to improving the fixation ability of bruises are rarely performed, and in the case of the patent literature, Korean Patent No. 10-1731229 and Korean Patent No. 10-1633822 The configuration of the weights for the shellfish shell fishing goggles of the present invention, which has been disclosed only for the capturing of the cephalopods, and for which the fixing force of the shellfish shellfish of the present invention can be reduced, is not disclosed.

1 shows a conventional shellfish shell fishing apparatus. Conventional webfoot octopus pot has a buoyant buoyancy which floats on the sea surface and floats on the surface of sea water indicating the position of the fishery. The buoy line connects the buoy to the fishing line, the buoy line and the buoy line horizontally It is made up of a corrugated string to be connected, a shell of shellfish that is installed on the corrugated lines and provides a fishing space, and a bruise and a bruise to the both ends of the corrugated string are fixed to the sea floor.

However, since the conventional bruise shape is a cube or a spherical shape, and the material used does not have a large difference in material properties such as stone or cement, the fixing force of the bruise depends on the weight of the bruise. Also, since the weight of the concrete weight is relatively weaker than that of the anchor in fixing the fishing gear, the frequency of the fish loss can be increased. Therefore, the present invention provides a fishing weight for fishing the shellfish shell having improved fixing force.

Hereinafter, a detailed description will be made with reference to drawings related to a weight for shellfish shell fishing gear of the present invention having improved fixing force.

Fig. 2 shows a weight weight for a shellfish shell fishing tackle improved in fixation force according to the present invention. The weighing main body 10 of the present invention has a polyhedron structure with a predetermined length and a converging part having a cross-shaped upper part formed on one side and a narrower width toward the other side. And a fixing device 11 is formed at the central portion of the criss-crossing upper side of the weight body in such a manner that the fixing device 11 is connected to and fixed to the wrist by a loop structure.

The weight body 10 of the present invention comprises a converging portion having a cruciform portion of a cross structure on the one side and a narrow width toward the other side, and the circumference of the weight portion 10 is concavo-convex. The converging portion is fixed to the seabed and formed to be heavier in weight than the cruciform portion. This is to improve the fixation force more than twice as compared with the conventional bruise, as confirmed in the experimental example to be described later.

In the weight weight according to an embodiment of the present invention, it is preferable that the weight of the convergent portion is formed such that 20% of the weight of the entire weight weight is concentrated. This is because the projections and depressions of the weight weight according to the present invention are deeply fixed to the bottom of the sea floor, It is for this reason.

Fig. 3 shows Embodiment 1 of the weight piece for shellfish shell fishing of the present invention with improved fixing force. The weights according to the first embodiment are structured such that the cruciform side surface and the fixing device are connected via the rod frame 12 of the stick structure. When the weight of the weight according to the first embodiment is larger than the moment of the weight, the convergence part can be heard and the fixing force can be reduced. Thus, the rod frame of the first embodiment can prevent this.

Fig. 4 and Fig. 5 show Embodiment 2 of the weight piece for shellfish shell fishing tackle of the present invention with improved fixing force. Although the material of the weight according to the first embodiment can be formed of concrete in the same manner as a conventional bruise, when the concrete is installed in seawater for a long period of time, the corrosion is great, and in particular, It is larger than a brick-shaped yoke.

The crisscross cover 13 is installed so that the crisscross portion can be inserted and fixed with a metal material having excellent durability according to the second embodiment, so that the crisscross portion of the weight portion main body is covered to reduce the breakage rate.

A fixing hole is formed in a side portion of the cross cover so that the rod frame can be inserted and fixed. A fixing device may be formed on one side of the rod frame so as to be connected to the barb. The other side of the bar frame may be inserted into the fixing hole and then caught by the fixing hole so that the rod frame is not separated from the cross cover. According to an embodiment of the latching device according to the present invention, the latching device is formed in a cross-shaped latching device so that the rod frame can move along the fixing hole, but is prevented from being detached from the fixing hole by the latching device.

Hereinafter, a description will be made of an experimental example for confirming the fixing force of the weight weight for the shellfish shell with improved fixing force according to the present invention. In general, the frictional force is determined by the coefficient of friction and the perpendicular drag (or weight) of the object against the surface. Therefore, if the physical properties of the friction surface and the weight of the object are the same, the frictional force is the same even if the shape of the object is different. The fixation force of the bruise is also determined by the fixed coefficient and the underwater weight of the object, and the fixed coefficient can be determined by the material and the quality of the bruise.

However, in the case of bruises, the bottom of contact with bruises mainly consists of sand or mud, so that the shape of the bruise is deformed during the movement of the object. Even if the weight of the object and the characteristics of the friction surface are the same, if the shape of the object is changed, there is a possibility that the brittle fixing force is changed due to the different degree of deformation of the brittle.

Therefore, the following experimental example according to the present invention is based on the fact that, in various form conditions of the weight, the area of the bottom surface of the bruise, the area of the cross-section (plane perpendicular to the moving direction), the shape of the cross- Respectively.

Experimental Example  One. Weights  Depending on floor area and cross-sectional area difference Fixing force  Difference

FIG. 6 shows five bruises having a rectangular cross-sectional shape in order to confirm the difference in fixing force between the weights according to the area difference of the bottom surface. The sectional area (3,025,000 mm3) and the length (200 mm) of each bruch were 0.011, 0.016, 0.019, 0.022, and 0.025 mm2 respectively (B1, B2, B3, B4 and B5) All the same.

FIG. 7 shows five bruises having a square cross-section in order to confirm the difference in fixation force between the weight cross-sectional area differences. A space was formed inside the bruch to increase the area of the cross section and to have the same weight. The cross-sectional area of each bruch was 3,025, 6,050, 9,075, 12,100, 15,125 mm2 (A1, A2, A3, A4, A5) and the volume of each bruch was the same (605,000 mm3). The open part of the front was blocked with a plastic panel (1 mm in thickness, ABS) to prevent the sand from entering the bore during towing. The clamping force was obtained by measuring the tensile force generated when the weight was pulled at a constant speed (0.35 m / s) by Loadcell. These experiments were performed 5 times for each model and the results were averaged.

Fig. 8 shows the change in tension acting on the bruise when the bruise B1, B2, B3, B4 and B5 are connected to the bruin and pulled at a constant speed. Fig. 9 shows the maximum value of the bruise tension. Experimental results showed that the tensile force applied to each of the bruises B1, B2, B3, B4, and B5 was almost constant over time, and there was no significant difference in the amount of tension depending on the bruise type. The maximum tensile strength of each bruch was similar.

FIG. 10 is a time series of the tension of the barb caused when each of the bruises A1, A2, A3, A4 and A5 is pulled, and FIG. 11 shows the maximum tension value of each barb. Experimental results show that the tensile forces acting on the bruises A1, A2, A3, A4, and A5, respectively, increase slightly and decrease with time, but remain almost constant throughout. There was no significant difference in the tensile strength between the types of bruises, and the maximum tension values were not significantly different.

The experimental results show that the fixation force of the bruise is not affected by the change of the bottom surface and the cross-sectional area of the bruch, and the characteristic is similar to that of general friction force.

Experimental Example 2. Difference in fixing force according to shape

이고 단면의 면적은 0.003025

로 모두 동일하도록 하였다. 고정력 측정은 상기 실험예 1과 동일하게 실시하였다.Fig. 12 shows a weight profile formed to confirm the fixing force according to the weight difference. (SQ), triangle (TR), circular (CI), coarse and small crisscross (CR-S), and elongated crisscross (CR-S) L). The weight of this shape is 0.000605

And the area of the cross section is 0.003025

Respectively. The fixing force was measured in the same manner as in Experimental Example 1 above.

FIG. 13 shows the tension of the bruises occurring when the bruises SQ, TR, CI, CR-S and CR-L are respectively pulled, and FIG. 14 shows the maximum tension. As a result of the test, it was found that the fixation force was higher in the order of the thin cross-shape (CR-L)> the coarse cross shape (CR-S)> the circular shape (CI)> the triangle (TR)> the square (SQ) The difference between the maximum bruising (CR-L) and the smallest bruch (SQ) was about the same for the maximal tensile strength, 2 times.

From the above results, it was confirmed that the fixation force between the bruises is remarkably different when the shape of the cross section is different. Particularly, the cross-shaped bruises have the greatest fixing power because the thin protruding parts of these bruises penetrate the sand bottom deeply and form a high resistance.

It is known that when the foundation is submerged or buried in the same weight as the concrete block, it receives not only its own weight but also the surface friction of the ground side, and the horizontal component force receives the frictional force of the bottom surface and the right and left earth pressure.

In the rectangular model, which is a control according to the experimental example of the present invention, since the degree of sinking in the submergence is small, the tension of the suture line is low due to relatively low surface friction or earth pressure on the ground side. In the case of the cruciform model, And the earth pressure were greatly influenced, and the bark tension was larger than that of the rectangular model. Therefore, it was confirmed that the fixation force of two objects having the same weight is different depending on the degree of sinking in the bottom.

Even with the same cross-shaped bruise, the longer the protrusion becomes, the higher the fixation force becomes. As a result, it can be seen that the more the bruise having the shape capable of deeply selling the floor, the better the formation of the higher fixation force. Therefore, even if the material and weight of the bruise are the same, it is considered that modifying the cross-sectional shape of the bruk improves the fixation force.

Experimental Example  3. Weights  Weight distribution Fixing force  Difference

FIG. 15 shows square bruises produced in order to confirm the fixing force according to the weight distribution difference in Experimental Example 3 according to the present invention. Experimental Example 3 according to the present invention was conducted in order to investigate the difference in fixation force according to the weight distribution. Six specimens of 50 g weight were put on a model having a square section (SQ) of the model according to Experimental Example 2, The difference of fixation force was investigated.

Once the bruised side is set to the front, for example, 5 pieces are placed in front of the bruise and 250 to 50 g if the back is placed. Experiments were performed on 4 cases with 300 ~ 0 g, 250 ~ 50g, 200 ~ 100g and 150 ~ 150g according to the distribution of weights on the bones. The measurement of the fixation force of the bruise was performed by measuring the tension on the bruise when pulling the bruise on the bottom at a constant speed.

Fig. 16 shows a water tank for towing the bruises. The towing tank (L2.0 × m) was pulled at a constant speed by hanging the bruise on the towing tank. The water tank consists of a tug and a drive train (25 w, torque 39.4 kgf · SPG Co., Ltd) towing the bruise, a tension meter (SUMM (SP) -10K, Max 100N , Senstech.CO, Korea) and tension data input system (AM-310, Senstech.CO, Korea).

The measurement frequency of the tension data was 200 Hz. For the sedimentation test, the digestible sand having a particle size of 2 mm or less was used. The nylon-coated stainless wire (0.5 mm) was connected to the center of gravity of the front face of the bruise and the bruise was level with the floor. The rate of bruising was 0.35 m / s. All experiments were performed 5 times for each bruise, and the results were averaged. The experiment was carried out at the Fisheries Technology Laboratory of the West Sea Fisheries Research Institute on September 1-15, 2017.

FIG. 17 is a graph showing the results of measuring the tensile strengths of the slacks measured in a time-series manner after arranging the weights on the SQ (rectangular parallelepiped) of 300 to 0 g, 250 to 50 g, 200 to 100 g, and 150 to 150 g, respectively And Fig. 18 shows the maximum tension. As a result, as shown in FIG. 17, in the initial stage of pulling the staples, the tensile strengths were similar to each other. However, as the time elapsed, the increase in the staple tension tended to increase as the front portion was heavier. As shown in Fig. 18, the maximum tensile strength was about 26% greater than the 150 to 150 g weightless condition, with 20% of the weight shifting to the front side in the 300 to 0 g condition.

From the above results, it was found that the fixation force increased with the weight of the front part of the bruise in the experiment according to the difference of the weight distribution of the bruise. This suggests that if the front of the bruise is heavy, the bruises tend to lean forward as the bruise progresses, forming a high resistance by digging into the sand bottom.

Thus, even if the bruise has the same weight, it can be seen that the higher the front weight, the better the fixing force. According to Experimental Examples 2 and 3, the increase in the fixation force of the bruise is considered to be caused by the protrusion of the bruise or the inclined front portion of the bruise common to the sand bottom during the process of bruising. This phenomenon coincides with the property that the anchoring force increases in proportion to the depth of the anchor's arm in addition to the weight of the anchor.

In general, when the weight of an object and the friction surface are the same, friction force, that is, force to pull the object is the same, but when the shape of the bottom is deformed in the course of pulling the object, The impact is reported to be large. Accordingly, the weights of the weights according to the present invention are heavier than those of the other weights, and the irregularities formed by the cross-shaped structure deeply digest the bottom of the sea floor and increase the fixing force.

Since the shell weight of the shellfish shell according to the present invention solves the problem that the shellfish shellfish is lost in the sea due to the low fixation force of the conventional shellfish weight, it can reduce the purchase cost related to the fishing cost, It is industrially applicable because it not only improves the profit of the workers but also helps to stock fishery technology.
