DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an observation equipment disposal apparatus.

[0002]

2. Description of the Related Art Conventionally, after using observation equipment in the deep sea, ascent and recovery have been performed by using a timed device, a command or cutting of a rope by an underwater vehicle, but when the recovery time is undecided or for a long time. After use, timed devices or commands often fail to operate due to contamination by marine organisms, corrosion, and the like. Also, in the case of recovery by cutting a rope with an underwater vehicle, it is easy to cut wire, but it is often difficult to cut Cremona rope, and when floating observation equipment during recovery, There was a risk that the vessel would collide with the capsule during or after ascent. Even in the case of disposal, it has conventionally been collected and then disposed of.

[0003]

In the prior art, collection and disposal must be performed even if collection is not necessary. Since recovery and disposal are performed after floating, it takes time and effort,
If the observation equipment in the deep sea cannot float and cannot be recovered, it will be left undiscovered until a means of recovery can be found, and it will easily flow out due to an accident or the like, causing marine pollution. In addition, it is necessary to collect, but it is difficult to break the rope,
Recovery may be difficult. The present invention solves the above-mentioned disadvantages of the prior art, and not only simplifies the collection of used observation equipment, but also floats and blasts in water without collecting.
It seeks to provide a means that can be destroyed.

[0005]

[Action] The underwater vehicle holding the observation equipment disposal tool is brought close to the observation cable (or rope) of the observation equipment, and the observation equipment disposal equipment is attached to the cable. At this time, the mooring cable (or rope) is fitted into the penetrating portion of the disposal tool via the discontinuous portion. The cable does not come off because there is a fall-off prevention bracket. After installation, the underwater vehicle departs from the danger area and sends a signal from it. The receiver receives it and sends air from the storage tank to the air bladder. The buoyancy causes the disposer to rise and collide with observation equipment maintained underwater. At this time, the explosive explodes due to the triggered firing mechanism,
If the observation equipment is safely blasted underwater, or
The rope can be cut at any position by the timed firing mechanism.

Numeral 11 denotes a stopper metal fitting provided in the interruption part 5, and when the mooring cable (or rope) 12 is pushed into the penetration part 4, the stopper metal fitting 11 is pushed open. Once the mooring cable (or rope) 12 enters the penetrating portion 4, the pull-out prevention metal fitting 11 has a structure that does not open in the reverse direction, so that the mooring cable (or rope) is prevented from coming off.

FIG. 3 is a perspective view showing a situation in which the observation equipment disposal tool 100 is attached to a cable (or a rope). In the figure, 13 is an underwater vehicle, 14 is a disposal tool holding device attached to the front of the marine vehicle, and 15 is a guide attached to the front end of the holding device. The holding device comprises a pair of left and right parts, holds the connecting portion 3 of the observation equipment disposal tool 100, and opens the left and right after the disposal tool is attached to the cable (or rope) 12 to release the holding. It is. Guides 15 integrally attached to the tips of the left and right portions of the holding device move together with the holding device.
