AUTOMATIC ANCHOR DEVICE FOR UNMANNED BOAT Russian patent published in 2022 - IPC B63B21/14 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and concerns the development of anchor devices for unmanned boats (hereinafter – UB). An automatic anchor device for UB equipped with a remote control system includes an antenna and a control unit, as well as it contains an anchor, an anchor winch placed on a deck of the boat and equipped with an electric drive, a coil of which is equipped with an anchor rope, an anchor hawse installed in a diametrical plane of the boat and made in the form of a sealed vertical pipe. The upper part of the pipe is made in the form of a deck anchor hawse, and the lower part of the pipe is made in the form of a niche for camping accommodation of the anchor. The anchor rope is fixed on the coil of the anchor winch with one end, and the second end of the anchor rope is passed through the anchor hawse and fixed on the anchor. In the anchor device of the boat, an anchor of a conical circular shape is used, and the anchor itself is structurally made of rigidly interconnected three parts: lower, middle, and upper. The anchor hawse niche is made of a conical circular shape with the possibility of camping accommodation of the anchor, so that the upper part of the anchor is placed in the lower part of the hawse cylindrical pipe, and the bottom of the lower part of the anchor is placed flush with the bottom of a boat hull. A locking device for camping retention of the anchor in the anchor hawse niche is made in the form of an electromagnet coil connected to the control unit, which is fixed on the outer wall of the anchor hawse niche at a level of location of the middle part of the anchor, when it is in the niche. The remote control system of the boat is additionally equipped with an echo sounder, a sensor of which is placed on the bottom of the boat, and a reed switch, which is installed on the outer wall of the lower part of the hawse cylindrical pipe, wherein the echo sounder and the reed switch are connected to the control unit.

EFFECT: unhindered anchor fallout under its own weight, unhindered anchor entry to a conical hawse, and increase in the reliability of an anchor device of a boat, when pitching on roughness, are achieved.
