KR-102963787-B1 - self destructing type underwater drone with wireless communication buoy

Abstract

The present invention relates to a self-destructing underwater drone having a wireless communication buoy, comprising: a main body equipped with an explosive consisting of an explosive and an igniter, which moves underwater by selective driving of a plurality of thrusters in which propellers rotate by motor driving; and a controller disposed on the main body that controls the operation of the thrusters and igniters; and further comprising a buoy located on the sea surface and equipped with a wireless communication module connected to the controller by a cable, wherein the operation of the thrusters and igniters is remotely controlled as a wireless signal transmitted from a remote control module at a remote location is input into the wireless communication module of the buoy and transmitted to the controller.

Description

Self-destructing underwater drone with wireless communication buoy The present invention relates to an underwater drone, and more specifically, to a self-destructing underwater drone having a wireless communication buoy, wherein a buoy equipped with a wireless communication module is connected to a main body located underwater, so that the underwater condition can be checked and the operation of the main body can be remotely controlled from a remote location, such as a mother ship located at sea, via wireless communication by the wireless communication module, thereby enabling the accurate selection of an attack target located underwater, and thus allowing the destruction of an attack target located underwater by self-destruction of the main body to be carried out smoothly. Recently, attacks using underwater weapons are increasing in situations of localized or full-scale warfare. In other words, there is an increasing number of cases where enemy ships and submarines are attacked using torpedoes and mines. Therefore, there is a growing need to prepare for attacks using underwater weapons in combat situations. Meanwhile, in preparation for attacks using underwater weapons, "underwater robots" that neutralize such attacks by colliding with and self-destructing underwater weapons have been proposed, as disclosed in Korean Public Patent No. 10-2014-0146282, etc. However, conventional underwater robots designed to self-destruct upon colliding with underwater weapons had a problem in that the remote control range via wireless communication fell short of expectations because the wireless communication module was installed within the main body located underwater, making it difficult to accurately select an underwater target and thus hindering the destruction of the underwater target through self-destruction. In addition, conventional underwater robots designed to self-destruct upon colliding with underwater weapons had the problem of being unable to precisely change direction during movement, making it difficult to destroy attack targets located underwater. To resolve this problem, attempts are being made to destroy underwater targets, such as underwater weapons, using the self-destruction of underwater drones. Underwater drones are not only small but also simple in structure, making manufacturing and maintenance easy. In particular, they can move freely up and down, forward and backward, and left and right underwater through the selective driving of thrusters deployed at multiple points, which allows for smoother destruction of attack targets located underwater. However, since the wireless communication module was installed within the main body of the underwater drone designed to self-destruct upon colliding with an underwater target, the remote control range via wireless communication fell short of expectations, resulting in a problem where the underwater target could not be accurately selected. For the reasons mentioned above, attempts are being made in this field to develop self-destructing underwater drones that allow for the smooth destruction of attack targets by self-destructing the main body, as the wireless communication range is expanded to enable smooth remote control and accurate selection of attack targets located underwater; however, satisfactory results have not been obtained to date.
