池塘养殖沉积物收集装置的研制

Design of sediment collection device for pond culture

为解决池塘固定沉积物集中收集的问题,设计了池塘养殖沉积物收集装置,主要由吸污装置、行走机构、控制系统和输泥管系组成。吸污装置利用污水泵将池塘底部的沉积物提升到岸上;行走机构的直流推进器为装置提供动力,实现自主行走;控制系统通过控制污水泵和两个推进器的工作状态,实现装置的运行。性能测试表明:沉积物收集装置在吸污作业时,行进速度需控制在0. 1 m/s以内,清淤时间在20～40 s范围内,可将固定点的沉积物完全吸除;吸污能力在0～14 m^3/h范围内,沉积物含泥量在0～12. 7 m^3/h范围内,沉积物浓度在0～35%范围内;整机配套功率为0. 9 kW,输送距离为100 m,空载噪声为52 dB。池塘养殖沉积物收集装置利用220 V的交流电作为电源,并采用隔离变压器与电网隔离后,再输送至池塘养殖沉积物收集装置的控制平台,安全性高,在池塘水体中运行范围大,实现了池塘养殖沉积物的集中收集。

In order to solve the problem of concentrated collection of pond sediment,a sediment collection device was designed. It mainly consisted of suction device,travelling mechanism,control system and floating pipeline. The suction device can lift the sediment to the bank by the sewage pump. The DC propeller of travelling mechanism provided power. The control system controlled the working state of the sewage pump and the two propellers to achieve normal operation of the device. Results of a series of tests on the mechanical properties revealed : The speed should be controlled within 0. 1 m/s in working operation;Staying between 20-40 s,the fixed point of sediment can be completely sucked;The capacity of sewage suction was 0-14m^3/h;The mud content was 0-12. 7 m^3/h;The sediment concentration was 0-35%;The power of machine supporting was 0. 9 kW;The idle running noise was 52 dB;the transmission distance was 100 m.The sediment device for pond culture used 220 V AC power is the power source. The power is isolated from the power grid by an isolation transformer,and then sent to the control platform of the sediment device for pond culture. It is high safety. The machine has the characteristic of large working area,which is conducive to the collection of pond culture sediment.
