Description

  The present invention relates to a drifting material collection guide method and a drifting material collection guide device.

Many drifting objects are floating and moving on the sea, but large trees, damaged wooden ships, or containers that have flowed out of capsized ships become obstacles to the navigation of ships.
Patent Document 1 discloses a drift container search method.

JP 2017-35951 A

The drift container search method described in Patent Document 1 has the following problems.
<1> A buoy that transmits position information is attached to a container with a magnet, and a crane boat for recovery uses the signal to search. However, even if the container sinks during drifting, It is a technical idea that the possibility of recovery can be increased because the sinking position can be specified by analyzing the signal accumulated in the signal and grasping the drifting path.
<2> An invention suitable not only to avoid the occurrence of secondary disasters when containers are scattered over the sea in the event of a marine accident, but also to achieve the purpose of collecting containers that store expensive items It seems to be. If so, it may be profitable even if complicated and expensive equipment is used.
<3> However, marine accidents in which containers are actually scattered rarely occur. It is more important to deal with drifting objects such as driftwood, fishing nets, and shipwrecks that frequently occur in the Sea of Japan.
<4> Since the frequency of such drifting objects is high, it is difficult to use a complicated and expensive device for each case as a countermeasure.

The present invention has been made in order to solve the above-described problems, and the drifting material collection and guidance method of the present invention includes a GPS transmission device that transmits surface information with buoyancy, and a buoyancy. A collection guide device is configured by a light emitting device that transmits information, the GPS transmission device, and a connecting member that attaches the light emitting device to the drifting object, and the transmitting device and the light emitting device are connected to the drifting object by the connection member. It attaches and guides the arrival of the ship which collects drifting material by a collection guide device.
The drifting material collection and guidance method of the present invention is characterized in that a rope with a hook is employed as the connecting member.
The drifting material collection and guidance method of the present invention is characterized in that a plurality of branch ropes are branched from the middle of the main rope, and a hook is attached to the tip of each branch rope as the connecting member. Is.
Furthermore, the drifting material collection and guidance method of the present invention is characterized in that a shaft and a sling that are driven by a water gun are employed as the connecting member.
In addition, the drifting material collection and guidance method of the present invention is characterized in that, as the above-mentioned connecting member, a hand hook is used in which the hook jumps out from the tip of the push rod toward the side surface.
The drifting material collection guide device of the present invention includes a GPS transmitter that transmits surface information with buoyancy, a light-emitting device that transmits point information with buoyancy, the GPS transmitter, and the light-emitting device. And a connecting member that can be attached to the drifting object.

Since the drifting material collection and guidance method and the drifting material collection and guidance apparatus according to the present invention are as described above, at least one of the following effects can be obtained.
<1> Due to the development of technology, it is only necessary to attach an inexpensive GPS transmitter and a cheap light-emitting device to the drifting object.
<2> A crane ship or the like for collecting drifting objects first grasps an approximate range by a GPS device that transmits information as a surface that is easy to grasp from a distance. Next, the drifting object itself can be approached by the light emitting device that transmits the point information. As described above, since the collection guide device of the present invention includes the surface information and the point information, even if the information is weak individually using an inexpensive device, the weakness of both can be compensated for economically. Guidance can be provided.
<3> The present invention is for preventing the occurrence of a disaster in which a ship collides with a drifting object, and is not a method for recovering a drifting object that has sunk under the surface of the water. Therefore, if the drifting object sinks by the arrival of the dedicated ship to be recovered, the navigation obstacle has been removed and no recovery is required. Therefore, the advanced technique of chasing a subsidence point in order to collect a container with economic value as described in Patent Document 1 is not necessary, and the object can be achieved by utilizing a commercially available simple device.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a drifting material collection and guidance method and a drifting material collection and guidance device according to the present invention will be described in detail with reference to the drawings.

<1> Overall configuration.
The method of collecting and guiding the drifting object 2 according to the present invention is a method that uses the collection guide device 1 that guides the position of the drifting object 2 when the dedicated ship for recovery arrives.
The collection guide device 1 includes a GPS transmission device 12, a light emitting device 11, and a connecting member 13.

<2> A GPS transmitter.
The GPS transmitter 12 that transmits surface information with buoyancy is configured by attaching the GPS transmitter 12 to a floating body made of plastic or foamed polystyrene.
The GPS transmission device 12 that transmits a position signal is commercially available at a low price as a vehicle tracking transmission device or a position transmission device for child safety.
Further, in the case of the present invention, since the recovery ship is guided in combination with the light emitting device 11, the GPS transmission device 12 only needs to be able to transmit with a rough range as a plane, and since it does not require a powerful power source, it is more inexpensive and stable in function. Equipment can be utilized.

<3> Light emitting device.
The light emitting device 11 having buoyancy and transmitting point information is configured by attaching a battery type light emitting body to a floating body made of plastic or the like.
For example, as the light emitting device 11 that lights up once every 4 seconds, a device that continues to emit light for 3 months with a single battery is commercially available at low cost.
The GPS transmission device 12 and the light emitting device 11 are mounted on the same floating body.

<4> A connecting member.
In order to attach the collection guide device 1, that is, the GPS transmission device 12 and the light emitting device 11 to the drifting object 2, a connecting member 13 is necessary.
Therefore, for example, a several-meter rope 13a with a hook 13b attached to the tip can be adopted as the connecting member 13.
The rope 13a is used so that it is thrown from the small-sized monitoring ship 3 which does not have a collecting device such as a crane and has a high traveling speed to the drifting object 2 and hooks the hook 13b, and then reaches the monitoring ship 3.
Alternatively, as the connecting member 13, a member in which a plurality of branch ropes 13 d are branched from the middle of the main rope 13 c and hooks 13 b are attached to the ends of the branch ropes 13 d, which is used for “rust fishing”, can be used. . A weight 13e is attached to the tip of the main rope so that the main rope 13c can be thrown far away. (Figure 3)
Also, a projection net can be used as the connecting member 13.
Alternatively, as the connecting member 13, it is possible to employ a water gun that drives a spear into the drifting object 2 with the elasticity of rubber. The rope has a rope at its tail end, and the recovery guide device 1 is connected to the other end of the rope for use.
Alternatively, a manual throwing technique can be employed. The hook jumps out from the tip of the handle toward the side, ensuring the drifting material 2 is secured.

<5> Recovery method.
As described above, the recovery guide device 1 of the present invention is equipped not only with a large crane ship but also with a small and fast monitoring ship 3 that can quickly find a drifting object 2 by traveling in a wide area. To do.
If you find the drifting material 2 from the surveillance ship 3 with binoculars, you will approach it.

<6> Installation on drifting objects.
When approaching the drifting object 2, the collection guide device 1, that is, the GPS transmission device 12 and the light emitting device 11 are attached by the connecting member 13.
As the method, the rope 13a with the hook 13b at the tip can be thrown to the vicinity of the monitoring ship 3, the drifting object 2 is rotated in the sea, the rope 13a is entangled, and the collection guide device 1 can be attached.
As shown in FIG. 3, when a plurality of branch ropes 13d are branched from the middle of the main rope 13c and hooks 13b are attached to the ends of the respective branch ropes 13d, they are entangled in a complicated manner by being caught by waves. , Capture is sure.
Instead of the rope 13a with the hook 13b, a commercially available fishing net for fishing can be used.
Alternatively, as the connecting member 13, it is possible to employ a water gun that drives a spear into the drifting object 2 with the elasticity of rubber. The rope has a rope at its tail end, and the recovery guide device 1 is connected to the other end of the rope for use.
Alternatively, a manual throwing technique can be employed. The hook jumps out from the tip of the handle toward the side, ensuring the drifting material 2 is secured.
Therefore, the same work can be performed not only from the monitoring ship 3, but also from the quay.
Thereafter, the GPS transmitter 12 and the light emitting device 11 attached to the other end of the rope 13a are lowered to the sea surface, and the role as the monitoring ship 3 is finished.
Since the light emitting device 11 attached to the drifting object 2 is turned on once every 4 seconds, for example, it has a collision warning function.
After that, the monitoring ship 3 reports to the Coast Guard Department and returns to the next monitoring and discovery work of the drifting object 2.
In response to the notification, the Coast Guard etc. dispatches a ship such as a crane ship to collect the drifting material 2.
The recovery ship can reach the approximate position of the drifting object 2 according to the GPS transmission signal of the guide device 1.

<7> Functions of the transmitting device and the light emitting device.
Since the GPS transmitter 12 transmits position information as a “plane” within a certain range, the recovery ship can approach to the vicinity of the drifting object 2.
After that, since the light emitting device 11 transmits the position information of the drifting object 2 itself as a “point”, the recovery ship approaches the drifting object 2 by visual observation and collects the drifting object 2 with a crane or the like to secure the safety of the channel. Plan.
Theoretically, the recovery ship should be able to approach the drifting object 2 with only the GPS transmitter 12.
However, the GPS transmitter 12 used in the present invention is planned to be in the tens of thousands of yen range. In the GPS transmission device 12 of that level, there is a possibility that an error of about 50 m occurs at the maximum. Therefore, the economical collection guide device 1 can be configured by using the light emitting device 11 that displays the drifting object 2 as “points”.
Apart from its economic efficiency, when the drifting object is directly under the surface of the water, it is difficult to find it with the GPS transmitter 12 alone, although it is dangerous. Even in that case, the existence of the light emitting device 11 showing the drifting object as a “point” is valuable.
In addition, since the GPS transmitter is rechargeable, radio waves can be transmitted only once per minute. When the wave is strong, it flows for a considerable distance in one minute, so that there is also an existence value of an economical light emitting device that continues to emit light once every 4 seconds for 3 months, for example, with a single dry battery.
