The invention discloses an intelligent multipurpose culture device, including a 
fodder throwing structure, an energy structure, a positioning structure, an 
oxygenation filter structure, and a detection structure. The 
fodder throwing structure comprises a top cover, a coaming, and a bottom plate. The energy structure comprises a 
lithium battery, a photovoltaic 
cell, a core motor, an 
intelligent management system, and a connecting plate. The positioning structure comprises a water wing, an 
impeller, a motor, a bearing plate, a strength support, an 
underwater range finder, and an ultrasonic rangefinder. The 
oxygenation filter structure comprises a structure main body, stirring blades, and a transmission shaft. The detection structure comprises a camera, a DO tester, a TDS detection pen, an electronic 
pH meter, and an electronic 
thermometer. The culture device satisfies monitoring of aquatic products from cultivation and transport sections to a sales section, and provides powerful supportfor 
food safety supervision and management. The device changes disadvantages that an existing culture device is single in function, low in blowdown rate, and high in improvement energy dissipation, and improves 
economic benefits. The structure of the device is improved and optimized, providing convenience for maintenance.
