Boat pole, for holding onto a metallic object, comprising: - a support rod (110, 210), - at least one magnet (120, 220), wherein the at least one magnet (120, 220) is attached to a first end (E1) of the support rod (110, 210), characterized in that the at least one magnet (120, 220) is designed as an electric magnet and at least one electric accumulator (160, 260) is arranged in the support rod (110, 210), which can be charged via a contactless charging device (300) and comprising a clamping device (310) in which an electric charging coil is arranged as a contactless charging device (300).

A method for coupling a retrieval cable to an object in a body of water, comprising the steps of: - providing an unmanned surface vessel (USV) comprising a pickup device, wherein the USV is coupled to a retrieval cable; - providing a pickup float coupled to said object, wherein said pickup float comprises an elongate pickup line and a floating member, wherein the pickup float is arranged to maintain the pickup line in a substantially horizontal and substantially elongate position without external support to the pickup float, on or near the water surface; - moving the USV towards the pickup float; - connecting the pickup device to the pickup float by piloting the USV over and across the pickup line.

This invention relates to the field of marine engineering technology, specifically to a device and control method for automatic locking and releasing of a ship. The device includes a ship end and a shore end. The ship end includes a hook, a push rod, a charging module, a communication module, and a control module. The shore end includes a crossbar and a discharge module. A positioning connection is established between the shore end and the ship end via a positioning module. The charging module has a voltage boosting function, converting the low-voltage electricity transmitted through the hook into high-voltage electricity to charge the ship end's power battery. The positioning module includes a satellite positioning device and an acoustic positioning device, enabling absolute positioning of the ship end and relative positioning with respect to the shore end. The communication module enables communication between the ship end and the shore end to obtain the shore end's position. In operation, this automatic locking and releasing device can achieve automatic locking and charging functions at the ship end, combining these two functions into one, ensuring reliable contact between the ship and shore metal contacts.

The present application relates to the technical field of small aircraft launching and recovering, and particularly relates to a small aircraft fast launching and recovering device based on the stern lines of a ship and a control method thereof. The small aircraft fast launching and recovering device is matched with the upper support of the small aircraft through a hook claw device, a camera recognition device, a pulley block, a steel wire rope, can realize the fast launching and recovering of the ship carrying the aircraft, and can reduce the weight of the ship during navigation, expand the working range of the aircraft, improve the navigation performance of the aircraft, and save the manufacturing cost of the connecting cable. The camera recognition device is used for image recognition, and the automatic control system of the pulley block and the electromagnet is combined, so that only one person is needed to control the aircraft during launching and recovering, the labor cost can be greatly saved, and the launching and recovering efficiency of the aircraft can realize the multiple launching and recovering of the aircraft in a short time.
