Conceptual Design Of A Device For Cleanup Floating Plants In Riverway

When the temperature rises between spring and summer,floating plants such as water hyacinth and duckweed are easy to breed in the river.These floating plants float in the upper of the water,which not only affects the visual landscape of the river but also destroys the ecological environment of the water.Compared with large rivers,small rivers are usually cleaned manually by sanitation workers with net bags and other tools,which is time-consuming and laborious.Therefore,the research on the floating plants cleanup device for small rivers has been put on the agenda.First of all,a field survey was carried out on the cleanup tools,working areas,and working processes used in the work of Santang River and its surrounding rivers in Shanghai,and it was found that the flooding of water hyacinth was the core problem.According to the research status of floating plant cleanup devices,a small floating plant cleanup device with miniaturization,modularization,and flexible use scenario is proposed.The function of the “Dragon-Bone” water lift to lift water from low place to high place is similar in action to the work of lifting floating plants from the water to the shore.Its advantages such as easy disassembly,easy maintenance,and easy movement meet the needs of small river floating plants cleanup devices.Therefore,this study aims to clean up water hyacinths in rivers,based on the shape and structure advantages of the“Dragon-Bone” water lift,carried out the design innovation of the new floating-water plant cleanup device.To obtain truthful information on the shape and structure of the “Dragon-Bone”water lift,field investigations were carried out on the “Dragon-Bone” water lift preserved in the Museum of Wuxi Wu Culture Park.According to the field observation and mapping,the shape,structure,and working principle of the“Dragon-Bone” water lift were recorded,and the digital restoration of the“Dragon-Bone” water lift was carried out with the method of 3D modeling.Secondly,based on the concept generation design methods of general design theory,the design process of the device is divided into four stages: confirming the product function of the cleanup device,selecting the temporary solution of the cleanup device,calculation of the transmission structure example model,and calculation of the refloat structure example model,and finally generated by inserting-refloating-shake-transport for action process for small river floating plants cleanup device concept.Based on this,through the methods of 3D modeling and entity model making,the transmission structure and the cleanup structure of the device were designed in detail,completed the input-output system of the device and the design scheme of the floating plant cleanup device.The design scheme of the device for cleanup floating plants in the river is composed of two parts: the "transportation system" and the "support system".The modular chain group is used as the basic unit to realize the transmission and cleanup functions,and the square wheels drive the rotation of the transportation chain.The detachable modular chain group and the square wheel drive are the innovation points of the design solution.Thirdly,use the Motion tool in Solidworks to start the motion simulation of the transmission structure of the device in an ideal state.By observing the simulation data of chain velocity and acceleration,the law of movement of the square shaft transmission is analyzed.Experimental data shows that the scheme has a "shake" feature in the horizontal transmission stage,which allows the device to shake off the water hanging on the floating plants during transportation so that it has a better water filtering effect in the actual cleanup process.Finally,based on the design scheme of the device,the design and application direction of the unmanned boat for cleanup floating plants with small rivers as the application scene is proposed,and the shape design of the unmanned boat is completed.Centered on the concept of the unmanned boat,further proposed a service system for the unmanned boat.Based on the shape and structure of the “Dragon-Bone” water lift,this study carried out the research of the small river floating plant cleanup device and completed the design proposal of an unmanned boat and service system,which has broad application prospects.
