Description

[Detailed Description of the Invention] The present invention relates to an underwater vehicle for disposing of explosives used in undersea construction and mines as underwater explosives.

Generally, when dealing with sunken mines, the method used is to remotely control an underwater vehicle to approach the mine, confirm the location of the mine, and then detonate the mine as a depth charge. However, in the past, the underwater vehicle was recovered and reused after mine disposal, which required an expensive guidance system and was designed to prevent the mine from reacting to the underwater vehicle and causing an early explosion. When designing and manufacturing an underwater vehicle, great care must be taken regarding its structure and materials in order to reduce noise generation and make it non-magnetic.Also, depth charges and their dropping equipment are required, causing significant damage. There is a problem in that it leads to higher costs.

The present invention aims to solve the above-mentioned problems associated with underwater disposal of explosives, and provides an underwater vehicle for explosive disposal that has a simple structure and can be manufactured at low cost by adopting a disposable method. The purpose is to

For this reason, the present invention provides an underwater vehicle for disposing of underwater explosives, which includes a signal processing electrical unit connected to a central processing unit of a waterborne workboat via an induction wire, and an acoustic signal processing unit of the workboat. It is equipped with a hydro-on that receives an ultrasonic beacon from a device and a thruster that drives the underwater vehicle, and the acoustic device transmits an ultrasonic beacon delivery signal sent in conjunction with the central processing unit from the hydro-on. A hydro-on reception signal circuit is provided to send a signal to the central processing unit via the signal processing electrical unit, and a control signal is sent from the central processing unit to the thruster via the signal processing electrical unit. The present invention is characterized in that a control circuit for transmitting the signal is provided, and an induction wire cutting mechanism that is operated by a signal from the signal processing electric unit and can cut off the induction wire.

Below, an underwater vehicle for explosive ordnance disposal as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a side view thereof, Fig. 2 is a system diagram showing its signal transmission system, and Figs. 3 and 4. The figure is an explanatory diagram showing the manner of its use.

As shown in FIG. 1, this underwater vehicle 1 includes propulsion,
Each thruster for winding and lifting (including motor) 2,
3.4 is installed on the tower, as well as an explosive charge 5 with a timer for mine clearance, a signal processing electrical unit 7 for sending and receiving various signals such as commands necessary for work, and a A hydrophon 8 for receiving a sonic beacon is mounted on the tower, and a battery 6 for supplying power to each thruster 2, 3.4 and electric units 1-7 is also mounted on the tower.

As shown in FIGS. 1 to 3, the underwater vehicle 1 and the work boat 13 are connected by an induction wire 10 for transmitting signals. A separation mechanism 9 is provided.

The timer-equipped explosive charge 5, the electric unit 7, and the battery 6 are each housed within the pressure shell of the underwater vehicle 1.

The signal transmission system for this underwater vehicle 1 is as shown in FIG. 2, and operates as follows.

The ultrasonic beacon emitted from the audio device 11 that is linked to the central processing unit 14 of the operating vessel 13 is received by the hydro-on 8 of the underwater vehicle 1, and then the delivery signal of this ultrasonic beacon is received by the hydro-on 8. The signal is sent to the signal processing electrical unit 7 via the hydrofon receiving signal circuit as an internal circuit, and is further transmitted to the signal processing electrical unit 1-7.
The received signal from each hydropon 8 is sent to the central processing unit 14 of the work boat 13 through the hydroponder 8 .

The central processing unit 14 has a control circuit that sends control signals to the thrusters 2, 3.4 via the signal processing electric unit 7, and the control circuit within the central processing unit 14 controls the acoustics of the work boat 13. The position, direction, attitude angle, etc. of the underwater vehicle 1 are calculated based on the signal output from the device 11 and the delivery signal of each hydropon 8, and the underwater vehicle 1 is directed to the preset target. Send control signals.

The signal processing electric unit 7 of the underwater vehicle 1 operates each thruster 2, 3.4 based on this control signal.

When the underwater vehicle 1 reaches the target position, the electrical unit 7 sends an induction wire disconnection signal to the induction wire disconnection mechanism 9 to activate it, thereby disconnecting the underwater vehicle 1 from the induction wire. After being separated from the underwater vehicle 10, the underwater vehicle 1 is used as it is as a depth charge for mine disposal, and the mine is detonated.

The operation status of this underwater vehicle 1 shown in FIGS. 3 and 4 will be explained as follows.

The underwater vehicle 1 that has been lowered into the sea by the work boat 13 starts in response to a command from the work boat 13, receives an ultrasonic beacon from the audio equipment 11 of the work boat 13, and transmits the delivery signal through the induction wire 10. By sending the control signal to the work ship 13, the control signal is received from the work ship 13, and the mine 15 as a target is
It will automatically sail towards.

The work boat 13 is equipped with a sonar to confirm the mine location, and the movement of the underwater vehicle 1 near the mine 15 can also be confirmed using this sonar.

When the underwater vehicle 1 reaches the target position, the induction wire 10 is cut off, and the explosive charge 5 is detonated by a timer to dispose of the mine 15.

The induction wire 10 is recovered after being cut off.

In addition, in the event that the mine 15 reacts with the underwater vehicle 1 and explodes while the underwater vehicle 1 is connected to the induction wire 10, the waterproofing of the induction wire 10 will be broken and seawater will enter the core wire. In order to prevent the entire induction wire from becoming unusable, an underwater connector 12 is provided at an appropriate position on the induction wire.

The features of the underwater vehicle of the present invention are as follows:
By installing a hydrophon 8 that receives an ultrasonic beacon from the underwater vehicle 1, it obtains information necessary for course control such as the position, azimuth, and attitude angle of the underwater vehicle 1, making it possible to automatically reach the target. This is because the underwater vehicle 1 itself is disposable.

In this way, since the operation of the underwater vehicle 1 is automated, various navigation patterns can be realized by the program of the central processing unit 14 loaded on the work boat 13 without requiring complicated manual operations. In addition, the underwater vehicle 1 requires only relatively inexpensive equipment, and by making it disposable, a depth charge dropping device or the like becomes unnecessary.

Furthermore, the main body of the underwater vehicle 1, which is difficult to manufacture due to its complicated shape because the explosive charge 5 with timer, battery 6, signal processing electric unit 7, etc. are housed in a pressure-resistant shell, is also for one-time use. It can be made of synthetic resin, which is inexpensive and easy to process.

In addition, since there is no need to reuse the motors for thrusters 2 to 4, it is easy to control the rotation speed, and a C motor can be used, which has the advantage of not using a conventional expensive AC motor with an inverter circuit. be.

In other words, since the underwater vehicle of the present invention is disposable, it can operate quickly and control the rotational speed easily, making it possible to fully utilize the advantages of the C motor.

Furthermore, when disposing of the mine 15, even if the mine 15 reacts with the underwater vehicle 1 and explodes, it can be considered that the mine 15 was disposed of normally, and therefore,
There is an advantage that there is no need to pay much attention to ensuring that the underwater vehicle 1 is not sensitive to the mines 15, and its design and manufacture are significantly easier.

As described in detail above, according to the underwater vehicle for explosive ordnance disposal of the present invention, by making it disposable, its structure is greatly simplified, and each equipment and material etc. There is no need to examine the matter from various viewpoints.
