This invention discloses an intelligent control optimization method for ship hybrid propulsion based on deep neural networks. By setting a generalized force control target, constructing a supervised training dataset, and establishing a deep neural network model with an encoder and decoder structure, the encoder maps the target generalized force to the thrust and angle commands of the propeller. The decoder outputs the generalized force inversely based on the control commands. During training, a multi-objective loss function with six sub-items is introduced to construct the physical constraints related to the propeller into the form of a loss function. The optimal propeller command that satisfies various constraints is found. The model receives real-time control command input and can quickly output propeller control commands that meet the constraints, realizing optimized thrust allocation. While ensuring that the physical constraints of the propeller are met, the method balances thrust allocation accuracy and energy consumption, accurately tracks while reducing energy consumption and excessive use of actuators, solves the ship thrust allocation problem under complex constraints, and efficiently completes the ship trajectory tracking task.

The utility model discloses a frame type hand washing basin handrail, including mounting panel, one side wall lower part symmetry of mounting panel is installed with two rotating frame, two rotating frame between common installation has a handrail frame, the handrail frame middle part with common installation has a spacing component between mounting panel upper portion, spacing component includes spacing hole, spacing column, shift block, spring, jack, insert column and fixed block. Advantageous effect lies in: the utility model discloses the cooperation design of mounting frame, rotating frame and spacing component, so that the frame type hand washing basin handrail can be folded according to actual use needs after using, effectively reduces the frame type hand washing basin handrail under the idle condition to the excessive occupation of bathroom space, is convenient for the full use of bathroom space, makes the frame type hand washing basin handrail use flexibility better simultaneously.
