我国广大的水网地区,内河航运有着重要的作用。但是由于内河河道复杂、季节水位变化大,船舶航行时,长期沿用竹竿测深的原始方法。每遇生疏及浅水航道,不管白天黑夜还是严冬酷暑,总有两名测水船员,分立两侧船弦,用测水竹竿测出河道情况,决定航行的转向及快慢进退。这种落后的测水方法既影响船员的安全健康,也在一定程度上影响了内河航运事业的发展。在全国农业学大寨会议精神鼓舞推动下,我们设计试 China’s vast network of water networks, inland navigation has an important role. However, due to the complexity of river channels, seasonal changes in water levels, the ship sailing, the long-term use of the original bamboo pole sounding method. In case of unfamiliar and shallow waterway, no matter day or night or severe winter, there are always two water surveyors, separate the two sides of the chord, measure the watercourse with a bamboo rod, and determine the direction of navigation and the speed of advance and retreat. This backward method of measuring water not only affects the crew’s safety and health, but also to some extent affects the development of the inland shipping industry. Under the encouragement of the spirit of the National Agricultural Science Dazhai meeting, we designed the trial
