Development Of Pond Cultivated Sea Cucumber Fishing Boat

With the change of people’s concept of health preservation,the demand for pond raised sea cucumbers has been increasing year by year.However,the existing manual fishing methods have high labor intensity,high fishing costs,and low capture efficiency.Designing an automated machinery specifically designed for pond raised sea cucumbers fishing has important practical significance and application value.This thesis uses TRIZ theory to analyze artificial islands for sea cucumber farming and sea cucumber fishing robots,and proposes improvement measures to address the shortcomings of both.Finally,a new sea cucumber fishing plan is proposed.Use TRIZ’s functional analysis to analyze the shortcomings of the existing artificial islands and reefs for sea cucumber breeding,and then use the characteristic transmission principle to propose an improved design,which embeds the hose into the artificial islands and reefs to increase the functions of the artificial islands and reefs;Use TRIZ’s functional analysis and causal chain analysis to find out the key shortcomings of the sea cucumber fishing robot,and then extract the core parts of the robot to organically combine it with the ordinary hull,and then design a new sea cucumber fishing boat.By combining new artificial islands and reefs with sea cucumber fishing vessels,a new fishing plan has been developed.The specific mechanical structure of the fishing boat was designed,and the specific functions of the fishing boat were divided into three independent modules: fishing module,expansion module,and support module.The connection mode,movement mode,and material selection between each module were described in detail.Afterwards,mechanical analysis was conducted on the main load-bearing components of each module,proving the reliability and rationality of the design.The fluid mechanics of the designed sea cucumber fishing boat was analyzed.An in-depth exploration was conducted from three aspects: ship stability,ship resistance,and ship power plant.For the stability of ships,calculations and discussions were mainly conducted on the center of gravity,buoyancy and stability positions of ships and fishing institutions,the anti overturning ability of ships,and the load capacity of ships;For ship resistance,friction resistance,viscous pressure resistance,wave making resistance,and attachment resistance were mainly calculated and simulated;For the power plant of ships,the main analysis is the thrust magnitude of the propeller and the interaction between the propeller and the hull.The overall electrical control system of the fishing vessel has been designed and divided into three modules,which respectively achieve fishing,telescoping,and cruising functions.Two STM32F103VET6 chips are used as the control core,with a single chip used for the fishing function.Through this design,the coupling between each module program is reduced and the stability of program operation is improved.For the fishing function,a master-slave control method is adopted,with STM32 as the host and K210 as the slave,respectively achieving water pump control and sea cucumber identification functions;For the telescopic function,use a handle to control its telescopic length;For the cruise control function,a combination of a handle,GPS,and gyroscope is used to achieve automatic traversal of the hull in the breeding pool.
