Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a submersible position indicating floater for fishing theft prevention and recovery,

The present invention relates to a fishing port used for indicating the installation position of a fishing net. In order to prevent theft, the fishing port is located at the bottom of the fishing boat for displaying the position. .

Generally, to capture fish in nearby coasts or rivers, the fishing net is installed under the water, and the rope connected to the fishing net is hung on the position indicator to display the position of the fishing net on the water surface It is well known that there is adopted a method of allowing the fishing nets to be easily retrieved by raising the fishing nets later.

In particular, in order to find a fishing net installed in a sea remote from the coast, it is needless to say that the fishing boat should be displayed using the above-mentioned fishing boat.

However, when the competition between nations and fishing vessels is intense, when fishing nets are displayed using the fishing nets, the position of the fishing nets is exposed and the fishing nets are stolen or the fishing nets around the marked fishing nets are intentionally damaged and collected. It is becoming a social issue, such as directly threatening the production activities of fishermen.

In addition, in the case where it is difficult to observe the naked eye due to the nighttime or the sea, there are frequent cases in which the marine vessel is caught in the screw of the vessel and the boat is lost. In this case, a simple hook-shaped object is dragged from the position of the fishing net recorded by GPS or the like, and the fishing net is hooked on the hook to find a fishing net in the water.

However, it takes a long time to find a fishing nets by the above-mentioned operation, and when the flow of the water fast is fast, the fishing nets are moved to another position beyond the expectation, have.

The fish nets that are not found in this way are present in the sea and cause a considerable economic loss to the fishermen. In addition, the sea environment is seriously polluted due to the lost seaworthy fishing nets and serves as the main culprit for destroying the ecosystem of the sea. Problems are pointed out.

Therefore, the Korean Utility Model Registration No. 20-379254 (name of the invention: a cigarette for preventing theft of the fishing nets and a convenience for recovering the fishing nets; hereinafter referred to as "cited invention 1") has been proposed, ),

1 and 2, the unit 100 includes a separation plate 2 for separating the case 1 and the inside of the case 1, and an upper receiving unit 110 defined by the separation plate 2, And a lower accommodating portion 120.

The case 1 has an elliptical shape in order to reduce an external impact or resistance in the water. The upper portion and the lower portion are divided into upper and lower receiving portions 110 and 120 with respect to the separating plate 2 and a lamp 3 and a power source portion 4 And a radio wave receiving unit 5 are provided.

It is preferable that the upper receiving portion 110 be sealed so that water does not permeate to the outside. Also, the space of the upper receiving portion 110 is filled with air, and the empty port 100 itself has buoyancy.

A lower receiving portion 120 defined by the separating plate 2 is formed below the upper portion 100. The lower receiving portion 120 includes a rope winding frame 6, a motor 8, Means 9 and a connecting rod 10 are formed and the guide portion 11 is formed at the lower end side inside the lower accommodating portion 120. [

The rope winding frame 6 is a means for winding the rope 7 connected to the proper position of the fishing net 12 and the locking control means 9 releases the rope 7 in a state of being wound, Is loosened when lifted above the sea level by buoyancy, or the rope 7 is kept in a wound condition so that it is not loosened.

In this cited invention 1, when the cigarette 100 receives a radio wave having a unique identification number through the radio wave receiving unit 5, the locking control means 9 connected to the motor 8 is operated to rotate the rope winding cradle Since the buoy 100 has its own buoyancy, the rope 7 wound on the rope winding frame 6 is loosened naturally by the buoyancy of the buoy 100.

As shown in FIG. 4, the float 100 floated above the water surface 13 makes it easy to find the floating float 100 even when it is dark, by the light emission of the lamp 3 at the top of the float 100.

The lamp 3 may be a light emitting unit that emits light by the power source unit 4, or may emit light by itself.

Therefore, since the lifted fishing rod 100 is lifted above the sea level by releasing the rope 7 wound by the transmission and reception of the radio waves, the ship operator can easily confirm the position of the fishing net 12, The fishing net 12 installed in the water can be easily raised.

On the other hand, such a cited invention 1 is required to receive a radio wave having a unique identification number through the radio wave receiving unit 5, but actually the radio wave receiving unit is not capable of performing its function in water,

In this reference 1, a large-sized rope having a length of up to 10 m has a large volume so as to be wound on the winding roll, and a motor and a speed reducer serving as a power source for winding the long rope and a clutch- And a large-capacity battery for driving the motor must be mounted. Thus, there is a problem that the structure is complicated and the manufacturing cost is excessively increased.

In addition, other types of submersible buoys, which are usually submerged below sea level and are elevated above sea level to check the nets used in the catch or culture, are disclosed in Korean Patent Publication No. 10-2013-0046038 A submergible buoy; hereinafter referred to as 'cited invention 2') has been proposed. As shown in FIG. 3, the motor 100;

A rotating body (200) coupled to a rotating shaft (110) of the motor (100) and rotated by a rotating force of the motor (100);

And is moved in the direction of the rotation axis 110 of the motor 100 in accordance with the rotation of the rotation body 200. The rotation of the rotation body 200 And a position indicating means 300 which is moved to one end or the other end side of the rotating body 200 and moves up from the rotating body 200 to the water surface when the rotating body 200 rotates in a specific direction,

A communication control unit 500 is formed on one side of the motor 100. The communication control unit 500 transmits a position signal of the position indicating means 300 and receives a float signal transmitted from the outside to drive the rotating shaft 110 in the motor 100. [ The submersible buoy according to Reference 2 can be operated by a worker to float and submerged buoys as needed, and the buoy is submerged below sea level, so that the effect of not being damaged by typhoons, high waves, and movement of a ship occurs.

In addition, the components that make the submersible buoy are simple, so the manufacturing cost is reduced and the operator can operate only when necessary to retrieve the net, trap, fishing nets, etc. installed on the buoy, and the buoy submerged below sea level The problem of theft of the fish was solved.

On the other hand, in Reference 2, it is inevitable that the submersible buoy is moved to the sea level and it is moved by the current. Therefore, at least when the submersible buoy ascends to the sea level, it immediately finds it, It is troublesome to search the fishing nets.

1. Registered Utility Model No. 20-379254 (Designed as: Designed to Prevent theft of Fishing Nets and Recovery Convenience) 2. Korean Patent Laid-Open No. 10-2013-0046038 (title of invention: submersible buoy)

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A specific embodiment of a position indicator 300 for preventing and recovering a fishing net 100 according to the present invention is shown in FIG.

As can be seen from the above description, the present invention is characterized in that a position indicating unit 300 is connected to one end of a fishing net 100 installed in the water by a rope 200, 100 as a separating means that is broken by being electrolytically broken by a current as well as a bundle so that the winding portion 201 is not loosened, A control unit 500 for receiving an ultrasonic signal transmitted from a work line and supplying a current flowing to the binding line 202 and the cathode plate 204 when a designated code and floating command code are decoded, And a casing 601 accommodated therein.

The negative electrode plate 204, which electrolyzes the binding wire 202 when power is supplied, is disposed on the bottom surface of the casing 601, and is shown only in FIG. 8 for convenience.

4, the fishing rod 300 is connected to one end of the fishing net 100 installed below the water surface by the rope 200,

Since the winding rope 200 is wound to form the winding portion 201 and the winding portion 201 is bundled with a binding wire 202 made of stainless steel which is not rusted in water, As shown in FIG. In this state, since any fishing line passing over the water surface can not find the fishing port 300, the position of the fishing net 100 is not exposed, so that it can be safe from cutting.

In this state, when a work line that manages the fishing net 100 approaches to collect or check the fishing net 100 and sends a float command signal from the onboard controller, the signal is transmitted through a transmission transducer (not shown) Which is received by a transducer 501 for ultrasound reception of the control unit 500 shown in Fig. 8, amplified by an amplifier 502, filtered by a filter 503, and then decoded by a decoder 504, Decoded into a code and applied to the controller 506.

As a result, the controller 506 controls the driver 505 only when the ID input by the controller 506 matches the corresponding ID and the command code is a float command, and the driver 505 controls the operation of the stainless steel material A current flows between the binding line 202 and the cathode plate 204 by flowing a current through the binding line 202 of the rope 200. Since the binding line 202 is electrolyzed and broken, At this time, as the buoy 300 rises by buoyancy, the buoy 300 rises up to the length of the rope 200 and floats above the water surface. Such a state is shown in Fig. Accordingly, according to the present invention, the fishing net 100 can be collected or the fishing net 100 can be inspected as the rope 200 is lifted by holding the fishing port 300.

The present invention can also be embodied in the form as shown in FIG. That is, according to the present invention, the position indicator 300 is connected to one end of a fishing net 100 installed in the water by a rope 200, and the length of the rope 200 is changed from the fishing net 100 to the water surface And the lower part of the lower rope 604 is connected with the fixture 400 fixed to the sea floor and the lower rope 604 in order to position the part 300 in the water. A coupling ring 203 connecting one end of the lower rope 604 to the port 300 as a separating means for disconnecting the connection between the port 300 and the lower rope 604, The cathode plate 204 may be configured to electrolyze the binding ring 203 at the time of power supply,

When the designated code and the floating command code are decoded by receiving the ultrasonic signal transmitted from the working line, a current flows through the binding ring 203 and the cathode plate 204 by the driver 505 of the control unit 500, So that the binding ring 203 is broken.

In this embodiment of the present invention, one end of a fishing net 100 installed in water is connected to a fishing port 300 by a rope 200, and the fishing port 300 is connected to the fishing port 300 The casing 601 is connected to the fixture 400 on the bottom of the sea via the coupling ring 203, and the casing 601 is connected to the sub- Since the connecting rope 604 is connected to the connecting rope 604, the auxiliary port 300 can not ascend and remains in the water.

In this state, when the work line for managing the fishing net 100 approaches to collect or check the fishing net 100, the ultrasonic signal is transmitted. The ultrasound waves are received by a transducer 501 for ultrasound reception of the controller 500 and amplified and filtered by a filter 503. The ultrasound waves are decoded by the decoder 504 and applied to the controller 506.

As a result, the controller 506 controls the driver 505 only when the ID input by the controller 506 coincides with the corresponding ID and the command code is a float command, and the driver 505 controls the binding A current is flowed through the ring 203 and the cathode plate 204 to electrolytically break the upper end of the lower rope 604 connected to the bottom fixing member 400 and the fastening ring 203 fastened to the bottom surface 400, And the lower rope 604 which has suppressed the downward rope 604. Accordingly, as shown in FIG. 7, the present invention allows the port 300 to rise by the length of the rope 200 and float above the water surface.

In addition, as shown in Figs. 9 to 12, the separating means of the present invention may be implemented by driving the hook 800 rather than the binding wire 202 or the binding ring 203 by electrolysis.

10, a space is provided below the casing 601, a motor 801 and a speed reducer 802 are provided on a lower substrate 602, and a speed reducer 802 So that the lower rope 604 can be bound and separated.

9, a speed reducer 802 that is operated by the motor 801 and a hook 800 that rotates by the speed reducer 802 are installed in a space provided below the control unit 500, Thereby restricting the upper portion of the lower rope 604 from binding with the upper end of the lower rope 604 as shown in FIG. In this state, if the code corresponding to the floating command is transmitted from the work line as described above, the controller 500 controls the controller 506 only when the ID data based on the ultrasonic transmission signal coincides with the corresponding ID and the command code is an floating command. The driver 505 controls the motor 501 so that the speed reducer 802 rotates the hook 800 as the separating means by rotating the motor 801 so that the lower rope 604 The upper hook and the hook 800 of the hook 300 are separated as shown in FIG. 11, so that the hook 300 is released from the restraint and the buoy 300 is lifted by its own buoyancy.

In particular, in the present invention, the motor 801, the speed reducer 802, the hook 800 and the like, which are separation means, are provided below the casing 601 together with the control unit 500, A separate casing for the separating means is unnecessary and the hooks 800 bound by the force corresponding to the buoyancy of the port 300 can be smoothly separated from the upper end of the lower rope 604. [

In this embodiment, it is unnecessary to spend time in the process of electric current flowing through the binding wire 202 and the binding wire 203 and the cathode plate 204 as shown in FIGS. 4 to 8, There is an advantage that the binding with the downward rope 604 can be quickly released in response to the signal transmission and the buoy 300 can rise.

In this case as well, as shown in FIG. 7, the buoy 300 rises up to the water surface by the length of the rope 200, and the operator of the work line holds the buoy 300 and pulls up the rope 200 The fishing net 100 can be retrieved or the fishing net 100 can be checked.

In this embodiment of the present invention, when the ultrasonic signal modulated by the floating command code and the ID designating the control unit 500 mounted on the specific unit 300 is launched from the work line, And is incident on the transducer 501 installed outside the control unit 500.
