An outboard motor locking device with integrated battery storage secures a portable outboard motor to a boat transom while providing protected battery mounting for electric start systems. A hinged lock bar having upper and lower members with cutouts surrounds the transom clamp screws of an outboard motor, preventing motor removal. A weather-resistant battery enclosure suspended from the lower member contains a marine battery with pre-installed wiring and external circuit breaker. When locked in position, the battery enclosure's access panel faces the transom, making the battery inaccessible without first removing the entire device. The integrated design provides theft deterrence for both motor and battery as a single unit. Electrical terminals extend from the enclosure for direct connection to the outboard motor. The device transforms complex marine electrical installation into simple attachment while meeting marine safety standards and keeping the battery elevated.

The application discloses a kind of marine safety evaluation methods, devices and equipment based on image recognition and medium, the method comprises: from the multi-view sea state image data detected to be identified object, and the object to be identified is matched with preset object, then the first satellite positioning information of current ship equipment is obtained, and the preset authority information of the object to be identified, according to relative position and first satellite positioning information, determine the second satellite positioning information of the object to be identified, if the second satellite positioning information matches the first preset sea area, based on multi-view sea area image data, determine the motion state information of the object to be identified, evaluate motion state information, obtain the safe navigation value of the object to be identified, if safety level is less than set level threshold, then based on ship equipment sends early warning alarm. So as to reduce the labor cost increased by manual detection, and improve the safety detection efficiency.

This invention relates to the interdisciplinary field of marine safety monitoring and computer vision, specifically to a precise early warning method and system for individual-level strong currents at the coast based on monocular time-averaged flow field reconstruction and spatiotemporal collision with tourists. The method includes the following steps: S1: Acquire coastal video images captured by a monocular camera, convert the coastal video images into orthorectified images using a homography matrix, and extract tracer particles from the orthorectified images; S2: Perform frequency domain cross-correlation calculations on two consecutive frames of the orthorectified images to obtain the instantaneous flow velocity field. This invention uses a lightweight time-domain sliding window integral combined with a fast Fourier transform, effectively filtering out wave interference and extracting a pure strong current flow field with very low computational power consumption, enabling the entire system to be processed in real-time directly on a common edge computing host at the front end.

A marine animal trap entry is assembled from a plurality of identically molded, semi-circular mating sections each including a semi-circular base and a plurality of flexible tapered fingers extending from the base. The plurality of mating sections are detachably assembled together to form an annular base portion and a tapered conical entry portion formed by the plurality of flexible tapered fingers. The plurality of fingers taper inwardly towards an apex of the conical entry portion wherein the annular base portion and conical entry portion are co-axial along a longitudinal axis of the trap entry. The semicircular mating sections are separated parallel to the axis of the trap entry. The plurality of flexible fingers are curved with an inwardly facing convex surface. Each of the semi-circular mating sections is molded from a biodegradable polymer.
