The application discloses a bridge mechanism of an amphibious bridge and belongs to the technical field of transportation. The bridge mechanism is suitable for the amphibious bridge and comprises a bridge span. The bridge mechanism comprises two middle bridge joints connected with each other, has a V-shaped bottom shape, and has a top plane structure used for passing of driving equipment; two end bridge joints connected to two ends of the two middle bridge joints through a bridge joint turnover mechanism, the turnover mechanism is used for lifting up the end bridge joints as the fulcrum relative to the connecting position with the middle bridge joints; and a plurality of air bag assemblies symmetrically connected to the side of the middle bridge joint. The amphibious bridge combines the land dry ditch bridge and the water ferry, can overcome the dry ditch obstacle on land and the river obstacle on water, and meets the double needs of smoothly passing the water and land obstacles.

The invention relates to an image analysis and AI video technology-based ship lockage and ferry safety intelligent supervision system. The system comprises a front-end multi-mode sensing system, a rear-end intelligent processing system, an early warning reporting system and a data middle station interaction module. The front end acquires high-quality data through a plurality of groups of multi-angle high-definition industrial cameras and a self-adaptive pan-tilt camera; the rear end is supported by an algorithm library to realize ship identity recognition, draft detection, ferry trajectory tracking and abnormal behavior recognition; the early warning system reports abnormal information in a grading manner according to severity; the data intermediate station module realizes bidirectional data interaction; ship draft detection is obtained through image preprocessing, identity recognition and freeboard height conversion calculation, ferry trajectory deviation is achieved through target detection, trajectory generation and direction included angle judgment, and the method aims at solving the problems that in the prior art, the function is single, the environment adaptability is poor, and safety parameter detection and data interaction capacity is lacked.

The utility model discloses a cableway ferry steering oar device which comprises a manpower steering engine, an output shaft of the manpower steering engine is connected with a spur rack meshed with the output shaft through a gear, and the spur rack is driven to move by rotating the manpower steering engine. The rudder steel cable is connected with two ends of the spur rack; the other ends of the rudder steel cables on the two sides are connected with the two ends of the connecting rod respectively; the rudder device comprises a rudder stock, a rudder pipe sleeve assembly and a rudder blade, the rudder handle is connected with the rudder stock, the rudder stock is rotationally and tightly matched with the rudder pipe sleeve assembly, and the rudder blade is fixed at the bottom end of the rudder stock; the pulley guides the rudder steel rope to move along a specified path; through cooperation of the manual steering engine, the rudder steel rope, the adjusting pull rod and the connecting rod, the two rudder blades can be operated at the same time, the efficiency of changing the sailing direction of the cableway ferry is remarkably improved, the workload of sailors is reduced, the operation convenience and comfort are improved, and therefore the overall shipping experience is improved.

According to the air film lifesaving device for the ship passenger cabin and the ship applying the air film lifesaving device, the supporting frame body and the air film cabin main body which is separately hung in or above the supporting frame body are arranged on the ship body deck of a small ship which cannot be provided with a lifeboat, and the supporting frame body sinks along with the ship under the condition that the ship sinks; however, the floating top surface, the cabin enclosure bulkhead and the floating bottom surface of the air film cabin main body adopt a composite structure of a floating material and an air film structure, and the air film structure is automatically or manually inflated after the air film cabin main body enters water, so that the air film cabin main body is separated from the support frame body under the action of water buoyancy and floats to the water surface to form a'lifeboat '; the safety and lifesaving capacity of the small passenger ferry is improved with the thought of solving the problem at low cost, the aim that rescue must be achieved when the small passenger ferry enters water and turns and sinks is achieved, and the prevention capacity for mass death and mass injury accidents of the current small passenger ferry is enhanced.

A system for powering an electric vessel includes a removable modular battery comprising multiple removable, rechargeable battery stacks. The battery stacks are arranged within one or more battery frames to facilitate the removal of depleted and / or damaged battery stacks and their replacement with charged battery stacks. A method for powering an electric vessel using the modular variable-capacity power system disclosed herein is also provided. The system and method are particularly suitable for vessels undertaking journeys involving one or more intermediate stops, such as ferries.
