The present invention relates to a mechanism for easily adjusting the depth of a fishing net during a fishing operation or in a meshed state, and a fishing net to which the apparatus is attached. In particular, the depth of the fishing net is controlled by injecting air or discharging air into the depth-controlled moxibustion. The present invention relates to a fishing net with a mechanism and a sphere mechanism.

There are several types of conventional fishing nets, including steamship nets, citron nets, wild nets, prehistoric nets, and low nets. The fishing nets are pre-nucleated according to fish species and fishing methods to be caught. Since the swimming layer is formed in a specific depth range according to the fish species, it is necessary to match the typical swimming layer of the fish species to capture the depth of the fishing net so that efficient fishing is possible. Conventional techniques for controlling the depth of fishing nets are well known and used (referring to Samjong Plate, Sam Byung-ki, Lee Byung-ki, Park Seung-won, Kim Jin-gun, Taehwa Publishing Co., Ltd.). This method is to adjust the depth of the fishing net by attaching foot stones.

1 is a schematic view of a conventional moxibustion. Connect the net (6) to the netting net (6) and fix the moxa wire (3) to the rim wire (4) of the protection net (5) and connect the moxibustion (1) with the moxa wire (2) to the moxa wire (3) The buoyancy of the moxibustion (1) is transmitted to the fishing net, while the sedimentary force acts on the fishing net by footsteps (not shown) which are sewn on a foot rope (not shown) attached to the bottom of the netting net (6). . Conventional moxibustion has been changed in the order of paulownia moxibustion, glass moxibustion, plastic moxibustion, and today Styropol moxibustion is mainly used.

Since the conventional moxibustion does not have a structure capable of injecting air into or injecting air out of the moxibustion, it is impossible to adjust the buoyancy of the moxibustion by injecting or discharging the air, and the material of the moxibustion. Depending on the size of the moxibustion and the buoyancy of the moxibustion is fixed constantly. Therefore, in the conventional fishing nets, a constant buoyancy and sedimentation force are acted upon according to the type and number of moxibustion and footings attached to the fishing net. Accordingly, the depth of the fishing net is fixed at a certain position, so the depth of the fishing net is arbitrarily adjusted. Can not.

Certain species swim in a typical stream, but the depths of the stream change depending on the season, weather, and time of day. There are many examples of changing the depth of swimming, but one example is as follows. The data on the stream of anchovies described on page 149 of the Introduction of the Offshore Fisheries (Samjeong Edition, Lee Byung-ki, Park Seung-won, co-authored by Kim Jin-gun, Taehwa Publishing Co.) shows that on sunny days from September to October, At sunset, the top of the anchovy stream is 4 to 5 m from the sea level and the bottom is 9 to 10 m, but at midday the top is 9 to 10 m from the sea level of the anchovy stream and the bottom is 17 to 18 m. Even during the day, the depth of the anchovy swimming layer changes by about 5 to 8 m.

Therefore, in the case of anchovy fish using citron network (see Introduction of Offshore Fisheries Samjungpan, Lee Byung-ki, Park Seung-won, co-authored by Kim Jin-gun, Taehwa Publishing Co., pp. 152 to 153), the depth of the net is adjusted by the length of the moxibustion line. In general, the fish finder checks the material of the fish, and then adjusts the depth of the fish in 10 m units by cutting a few moxa wires made in 10 m units.

However, in fishing works using steamship nets, field nets, chat boats, preliminary nets and low nets, fishing is carried out without the operation of determining the depth of the net by the length of the moxibustion line.

As in the above, the conventional technique of operating the fish without adjusting the depth of the fishing net, or adjusting the depth of the fishing net by adding or subtracting the moss connecting wire before the netting, as in the case of anchovy fishing using a citron net, Since the depth of the fishing net cannot be adjusted quickly due to the fluctuations in the depths of the fisherman's stream, the effective catch is impossible and the catches are greatly reduced.

Therefore, an object of the present invention is to provide a depth control mechanism for fishing nets and a fishing net with the apparatus that can adjust the depth of the fishing net quickly and easily in the catching operation or in the netted state according to the fluctuation of the depth of the swimming layer of the fish group. .

Another object of the present invention is to quickly and easily remove a line such as a claw line, for example, when a raft line is lifted by a fire to block the retreat of a fish during a catching process such as anchovy using a net. SUMMARY OF THE INVENTION An object of the present invention is to provide a depth control mechanism for a fishing net that can be used as an auxiliary mechanism for lifting and a fishing net to which the apparatus is attached.

Another object of the present invention is to provide a depth control mechanism for a fishing net that can be used as an auxiliary mechanism that enables both nets to be quickly and easily and a fishing net to which the apparatus is attached.

In order to achieve the above object, in the present invention, at least one or more control moxibustion that can inflate or discharge air and expand or contract as air is injected or discharged, at regular intervals in the middle of the moxibustion line Wrap the moxibustion moxibustion protector to protect the moxibustion, and connect the air hose to the moxibustion to supply air to the moxibustion or discharge the air from the moxibustion with the air compressor or vacuum pump installed on the ship. It is effective to control the depth of the fishing net by constructing the depth control mechanism for the fishing net, and attaching such a mechanism to the fishing net with a fixed strap so as to supply air to the regulating moxibustion or to discharge the air from the regulating moxibustion according to the change in the depth of the fisher's stratum. Fishing was possible.

Referring to the present invention in detail based on the accompanying drawings as follows.

2 is a schematic view of the depth control mechanism for fishing nets according to an embodiment of the present invention, (A) is a schematic diagram showing a state in which air is discharged from the inside of all the moxibustion (10, 10 '). The air hose 12 'is attached to the moxibustion line 3 with a fixing cord 13', and the air hose 12 branched to communicate with the air hose 12 'is fixed to the moxibustion cord 2 (13). ) And at least one adjustment moxibustion (10,10 ') is connected to the air hose 12 at regular intervals, and the adjustment moxibustion protection (11,11') is wrapped around the adjustment moxibustion (10,10 ') for adjustment. It is composed of a structure to protect the moxibustion (10, 10 '), the remaining components are the same as the conventional moxibustion.

2B is an air supply and air discharge system by connecting one side of the air hose 12 to the air supply and air discharge system (refer to FIG. 3, described later) installed on the ship. By discharging air from the inside of all the control moxibustion (10,10 ') by shrinking all the control moxibustion (10,10') (see also FIG. 3, described later) by all the control moxibustion (10,10 ') The buoyancy does not work, but only the buoyancy by the conventional moxibustion (1) is in a state that the depth of the fishing net is adjusted to the maximum depth.

Adjusting moxibustion (10, 10 ') is an empty structure except for the portion communicating with the air hose (12, 12'), and is preferably spherical, cylindrical, conical, etc., but the shape is not limited. Flexible moxibustion (10,10 ') material is flexible, and it is easy to expand and contract the moxibustion (10,10') according to the supply and discharge of air, and the pressure of several to several tens of atmospheres is repeated. It can be used if it has durability that does not break even. For example, rubber, synthetic resin, resin-coated impervious fabric can be selected and used.

Moxibustion protection device (11, 11 ') wraps the control moxibustion (10, 10') to protect the control moxibustion (10, 10 ') from breakage, and can be manufactured by selecting from fabric, net, synthetic resin film, plastic, etc. , When the expansion and contraction of the control moxibustion (10,10 ') with the expansion and contraction, or during the expansion and contraction of the control moxibustion (10,10') and the moxibustion protection (11,11 ') and the control moxibustion (10,10) The moxibustion protection devices 11 and 11 are provided with a gap or a hole to facilitate the entry and exit of seawater in the space between the ')'.

Adjusting moxibustion (10,10 ') and moxibustion protection devices (11,11') of the upper and lower parts are made of different colors, respectively, and control moxibustion (10,10 ') and moxibustion protection devices (11,11) floated on the sea surface. The color of ') makes it easy to judge the depth of fishing nets.

As the air hoses 12 and 12 ', a conventional air hose made of a flexible material used in connection with a vacuum pump is used.

As the fixing straps 13 and 13 ', conventional strings or strings used in the manufacture of fishing nets are used.

FIG. 2B is a schematic view showing a state in which air is injected into the upper one moxibustion 10 and air is discharged from the inside of the remaining control moxibustion 10 '. In the state where the depth of the fishing net is at maximum depth as shown in Fig. 2A, as shown in Fig. 2B, the length between the conventional moxibustion 1 and the upper moxibustion for adjustment 10 (e.g., 5) The method of shallowing the net depth of the fishing net by m is as follows.

Assuming that the interval between the conventional moxibustion 1 and the upper control moxibustion 10 and the interval between the upper control moxibustion 10 and the lower control moxibustion 10 'are 5 m, respectively, as shown in FIG. In the case of a), the upper moxibustion (10) is pressured by seawater at about 0.5 atmosphere (unless otherwise stated, the gauge pressure), and the lower moxibustion (10 ') is controlled by seawater. Under pressure Moxibustion for controlling air of 0.6 to 0.7 atm through the air hoses 12 and 12 'by the air supply and air discharge system (see FIG. 3, described later) installed on the ship in this state. ') Is supplied with most of the air to the upper control moxibustion (10') under the pressure of about 1 atm and almost no air is supplied to the upper control moxibustion (10) under the pressure of about 0.5 atm. . As air is supplied to the upper regulating moxibustion 10, the upper regulating moxibustion 10 expands, and as a result, buoyancy is applied to the fishing net by the upper regulating moxibustion 10, as can be seen from the Archimedes principle. Will work.

As the moxibustion 10 on the upper side expands and buoyancy acts on the fishing net, the fishing net rises, and when the moxibustion 10 on the upper side approaches sea level, the moxibustion 10 'on the lower side becomes shallower. Since the pressure acting by the sea water is reduced, air is also supplied to the lower moxibustion 10 '. Therefore, when the upper control moxibustion 10 begins to approach the sea level, the pressure of the supplied air is lowered to 0.3 to 0.4 atm by the air supply and air discharge system (see FIG. 3, described below). ') Is hardly supplied with air, and only air is supplied to the upper moxibustion 10 on the upper side. In this way, by supplying air while adjusting the pressure, when the upper moxibustion control 10 reaches the sea level, the supply of air is stopped and the upper portion present on the sea surface when the air pressure inside the control moxa 10 is maintained at about 0.2 to 0.4 atm. The buoyancy is transmitted to the fishing net by the moxibustion of the control 10, the depth of the fishing net is maintained as shallow as the length between the conventional moxibustion 1 and the moxibustion 10 of the upper portion.

(C) of FIG. 2 is a schematic diagram showing a state in which air is injected into all the moxibustion 10, 10 '. In the state of (b) of FIG. 2, since the lower moxibustion 10 'is under a pressure of about 0.5 atm by seawater, when air is supplied to the lower moxibustion 10' at a pressure of 0.6 to 0.7 atmospheres. Since the lowering moxibustion 10 'expands and floats to the sea level, it is in the state of FIG. 2, and as a result, the depth of the fishing net is adjusted to the shallowest state.

If the air is supplied to the regulating moxibustion 10,10 'at the pressure of 1.1 to 1.5 atm in the state of (a) of FIG. 2, all the regulating moxibustion 10,10' expands and floats to the sea level. C), and as a result, the depth of the fishing net is adjusted to the shallowest.

In (C) of FIG. 2, when the air is discharged from all the inside of the control moxibustion (10, 10 '), the control moxibustion (10, 10') is contracted to lose buoyancy and settle from the lower control moxibustion (10 '). . The lower moxibustion 10 'is settled and the upper moxibustion 10 is stopped when the upper air is not settled or the air is supplied again to maintain the pressure of the supplied air at a level of 0.2 to 0.4 atm. The moxibustion for control of 10 is present in the expanded state on the sea surface and the moxibustion for adjustment (10 ') of the lower is contracted to lose buoyancy and exist below the sea level to be adjusted to the state of (b) of FIG. In the state of (B) or (C) of FIG. 2, the air is discharged from the inside of all the moxa (10, 10 ') to maintain the air pressure below the atmospheric pressure. Since moxibustion (10.10 ') loses buoyancy due to contraction, all the regulating moxibustion (10,10') is settled and adjusted to the state of (a) of FIG.
