DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a submerged sediment separating structure for an outer cylinder, and more particularly, to a submerged sediment, which is settled quickly while integrally holding an upper outer cylinder and a lower outer cylinder, and stored in a lower outer cylinder. The present invention relates to a submerged sediment outer cylinder separation structure capable of shortening the waiting time until a used acoustic sensor or the like is used.

[0002]

2. Description of the Related Art Conventionally, a measuring device such as an acoustic sensor is suspended at a predetermined depth from a buoy floating on the sea surface via a cable, and measurement information is transmitted to a station on a ship or on the ground via the buoy or the like. That is being done.

For this purpose, for example, Japanese Patent Application Laid-Open No. 9-52
In Japanese Patent No. 595, the sea anchor 51 is housed as shown in FIG. 8 in order to reliably pull out the sea anchor together with the case from the sedimentation container in the sea and to exhibit the book. When the case 52 is pulled out of the sedimentation container through the draw-out cable 60 and the branch portions 61 and 62 in the sea, the case bodies 53 and 54 are cracked open by the spring force of the respective plate members 56, and the upper end of the plate member 56 is also closed. The case body 53, 54 falls out of the groove of the body 55 and
And the lid 55 are disassembled, whereby the sea anchor 51
Is disclosed in which a book is released from a case 52 and booked by an ocean current.

In Japanese Patent Publication No. 4-43034, a parachute is used to drop an aircraft, detect underwater sound and convert it into an electric signal, and then transmit the detected signal to an airborne or maritime aircraft or ship. A sonobuoy installation device with an automatic wireless transmitter is disclosed. This device is highly reliable and inexpensive, for example, by operating a one-short spring motor fixed to the canister by an underwater operation battery.

Further, Japanese Patent Application Laid-Open No. 60-157059 discloses a sonobuoy deployment device. In this device, an underwater operation battery is used, and an acoustic sensor is suspended at a preselected depth in the sea. It is configured as follows.

[0006]

However, the above-mentioned prior art has the following problems.

[0007] For example, in the outer cylinder separating structure of a submerged sediment described in Japanese Patent Application Laid-Open No. 9-52595, the pull-out cable 6
Since 0 exists outside the case 52, a desired operation may not be able to be performed due to being caught on an unexpected portion during the operation.

On the other hand, the devices described in Japanese Patent Publication No. 4-43034 and Japanese Patent Application Laid-Open No. 60-157059 require power for rotating a column or the like. There is a problem that the size is increased.

The present invention has been made in view of the above-mentioned problems in the conventional apparatus, and has high reliability for the apparatus, low power consumption, small size, and waiting time until an acoustic sensor or the like is used. It is an object of the present invention to provide a submerged sediment separating structure of a submerged sediment body which can shorten the time and has good operability.

[0010]

In order to achieve the above object, an invention according to claim 1 is an outer cylinder of a submerged sediment body connected to a buoy via a suspension cable and comprising an upper outer cylinder and a lower outer cylinder.

The member urges the two exterior cylindrical retention plates in directions approaching each other, the trigger member is interposed between the two exterior cylinder retention plates, and tension is applied to the suspension cable. Sometimes, the engagement between the trigger member and the outer cylinder retaining plate is released, and the outer cylinder retaining plate moves in a direction in which the protrusion of the outer cylinder retaining plate moves away from the engagement hole of the lower outer cylinder. Features.

Further, according to a third aspect of the present invention, the trigger member is rotatably held by the upper outer cylinder, and has two substantially rectangular parallelepiped stoppers; and the two stoppers. And a raising plate provided at an intermediate portion of the shaft, one end of which is fixed to the shaft, and the other end of which is connected to the suspension cable, wherein tension is applied to the suspension cable. Before being added, the raising plate is in a state of lying horizontally, and the stopper is interposed between the two outer cylinder retaining plates and is in contact with each of the two outer cylinder retaining plates. When tension is applied to the suspension cable, the raising plate shifts to a state in which the lifting plate is raised in the vertical direction.゜ By rotating and switching the contact surface of the stopper with the two outer cylinder retaining plates, the projections of the two outer cylinder retaining plates are moved in a direction away from the engagement holes of the lower outer cylinder. It is characterized in that the two outer cylindrical retaining plates move.

According to a fourth aspect of the present invention, the trigger member is a stopper formed in a substantially cylindrical shape.

Characterized in that the two outer cylindrical retaining plates move in a direction away from the outer cylinder.

According to the present invention, the submerged sediment sinks in the water while the upper outer cylinder and the lower outer cylinder remain integral with each other until the extension of the suspension cable is completed, and the extension of the suspension cable is completed. Then, the submerged sediment stops, tension is generated in the suspension cable, and the projection of the outer cylinder retaining plate separates from the engagement hole of the lower outer cylinder, so that the lower outer cylinder falls off from the upper outer cylinder. Therefore, the sedimentation speed of the submerged sediment can be increased, and the waiting time until the acoustic sensor or the like stored in the lower outer cylinder can be used can be shortened.

Further, since the suspension cable can be accommodated in the upper outer cylinder, there is no possibility that the suspension cable may be caught by an unexpected part existing outside the upper outer cylinder during operation.
The reliability of the device can be improved.

Further, in the outer cylinder separating structure of the submerged sedimentary body, in the operation from the unwinding of the suspension cable to the dropping of the lower outer cylinder from the upper outer cylinder, no power from a submarine-operated battery or the like is required. The power consumption is small and the device can be made small.
