A navigation light adjustment method and system are disclosed, relating to the field of navigation light technology. The method involves acquiring vessel information and visibility for all vessels within a predetermined water area; determining the vessel density within the predetermined water area based on the vessel information; dividing the predetermined water area into multiple adjustment zones based on the vessel density; calculating the comprehensive navigation condition value for each vessel within each adjustment zone based on the visibility and vessel density; obtaining the navigation routes for each vessel within each adjustment zone; and adjusting the parameters of the navigation lights for each vessel within each adjustment zone based on the navigation routes and the comprehensive navigation condition value. Implementing the technical solution of this application allows for analysis of the surrounding navigation environment and timely adjustment of navigation lights, thereby reducing the probability of vessel collisions.

This application relates to a motor heat dissipation mechanism for a vacuum cleaner, belonging to the field of mechanical heat dissipation. It includes a stator, a rotor, an air inlet housing, a rotating shaft, an end cover, a moving impeller, and a first stationary impeller. The stator is fixed inside the first stationary impeller, and the moving impeller is located inside the air inlet housing. There is a gap between the outer circumferential wall of the moving impeller and the inner wall of the air inlet housing. The first stationary impeller is fixedly connected to the end cover, and the rotating shaft is rotatably connected to the first stationary impeller. A cooling air duct is provided between the inner wall of the first stationary impeller and the outer wall of the stator. A baffle shell is fixedly provided on the outer circumferential wall of the first stationary impeller and is fixedly connected to the air inlet housing. A second stationary impeller is coaxially fixed at the end of the first stationary impeller near the moving impeller, and the outer circumferential wall of the second stationary impeller is in contact with the inner wall of the air inlet housing. A cover plate for mounting a circuit board is fixedly provided at the end of the end cover away from the first stationary impeller, and the end cover has several ventilation holes. This application has the effect of reducing dust accumulation in the vacuum cleaner motor and achieving simultaneous and efficient heat dissipation.
