Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separating device with a cable cutting machine for an underwater observing equipment fixture for separating an underwater observing equipment and an underwater fixture in water such as the ocean, lakes, rivers, and dams.

[0002]

2. Description of the Related Art Underwater observation equipment 20 (see FIG. 3) is used for investigating heat flow rate and water temperature in a bottom sediment under water.

The underwater observing device 20 is fixed to the bottom of the water by an underwater fixture 21 for underwater observation. The underwater fixture 21 includes a separating device 40 (see FIG. 5) and a cable cutting machine 4
5 (see FIG. 6) is fixed. The underwater observation device 20 and the underwater fixture 21 are connected by using a fastening bolt having a hole fixed to the underwater observation device 20. Further, the underwater observation device 20 is equipped with an ultrasonic transponder 22 having a built-in driving power source, and when the ultrasonic transponder 22 receives an ultrasonic signal, the ultrasonic transponder 22 instructs the driving power source to pass a current through the cables 15 and 46.

As shown in FIG. 5, the separating device 40 has a piston 37 with an internal injection pipe having an injection port 39 inside the container.
Is stored. For the piston 37 with internal injection pipe,
The gas generator 41 is fitted. The piston 37 is slidably in close contact with the inner wall of the container, and the piston rear end portion 42
Is inserted into and engaged with the hole of the square rod 5 connected to the fastening bolt. The cable 15 is connected to the gas generator 41.

When electric current flows through the gas generator 41 through the cable 15, gas is generated and injected from the injection port 39,
The piston 37 with the internal injection pipe is pushed out of the container together with the gas generator 11, and at the same time, the piston rear end portion 42 causes the square rod 5 to move.
It is pulled out from the hole and the engagement is released.

As shown in FIG. 6, the cable cutting machine 45 accommodates a gas generator 48 and a piston 49 side by side inside a container, and a cable 15.4 is inserted in a through hole formed in the container.
6 penetrates and the cable 46 is connected to the gas generator 48. The piston 49 is slidably in contact with the inner wall of the container, and a cable cutting blade 50 is fixedly attached to the tip thereof.

When an electric current flows through the gas generator 48 through the cable 46, gas is generated and the pressure thereof pushes the piston 49, whereby the cables 15 and 46 are cut by the cable cutting blade 50.

When the ultrasonic signal is transmitted from the ship, the ultrasonic transponder 22 receives the ultrasonic signal, and the driving power source supplies the cable 15.4 to the separating device 40 and the cable cutting machine 45.
An electric current is passed through 6, the square bar 5 is detached from the separation device 40, the cables 15 and 46 are cut, and the underwater observation device 20
The buoyancy of the float 25 floats up to the surface of the water and is collected.

When the gas generator 41 of the separating device 40 and the gas generator 48 of the cable cutting device 45 are operated at the same time, the cable cutting device 45 operates first due to variations in gas generation, and the current stops flowing to the separation device 40. Since there is a case where the underwater observation device 20 cannot be collected without doing so, a timer or a relay for delaying the current supply to the cable cutting machine 45 for 10 to 100 milliseconds may be used, or the power supply may have two series.

[0010]

As described above, since the separating device 40 and the cable cutting machine 45 are conventionally separated from each other,
Since many parts are required, the manufacturing cost is high, and in addition to a large amount of cables and power supply capacity, a timer and a relay are required, and a large installation space is required, it is troublesome to install.

The present invention has been made to solve the above-mentioned problems, and can reliably collect underwater observation equipment, does not require many parts, is low in manufacturing cost, requires less cables and power supply capacity, and can be used as a timer. It is an object of the present invention to provide a separating device with a cable cutting machine for an underwater observation equipment fixture, which does not require a relay or a relay and does not require a large installation space.

[0012]

As shown in FIG. 3, a separation device 10 with a cable cutting machine for an underwater observing equipment fixture of the present invention, which has been made to achieve the above-mentioned object, has a structure as shown in FIG. In the fixed engagement member 5 on the underwater fixture 21 side,
The movable engaging member 6 of the underwater observing equipment fixture to which the movable engaging member 6 (see FIG. 1) on the underwater fixture 21 side or the underwater observing equipment 20 side is engaged and connected is disengaged. An apparatus for separating the underwater observing device 20 and the underwater fixture 21, which is provided with the movable engaging member 6
The closed chamber 4 shown in FIG. 1, the gas generator 11 having the gas injection space therein and the piston moving in the closed chamber 4 by using the gas injection pressure as a driving source are provided on the 0 side or the underwater fixture 21 side. Then, the movable engaging member 6 is connected to one end of the piston, and the cable cutting blade 9 is fixedly provided at the other end, and the cable 15 that connects the underwater fixture 21 and the underwater observing device 20 on the movement trajectory of the cable cutting blade 9. Is located.

It is preferable that the drive power source of the gas generator 11 disposed on the underwater fixture 21 side is disposed on the underwater observation device 20 side, and the cable 15 connects the gas generator 11 and the drive power source. Further, a transponder 22 is mounted on the underwater observation device 20 side, and the driving power supply supplies power to the gas generator 11 by a trigger signal from the transponder 22.

[0014]

With this structure, when gas is generated from the gas generator 11, the piston is pushed by the pressure and the engagement between the movable engaging member 6 and the fixed engaging member 5 is released, and the cable is released. After the separating device 10 with a cutting machine and the fixed engagement member 5 are separated, the cable 15 is cut. That is, the separating device with a cable cutting device 10 surely operates both the cable cutting device and the separating device.
