回声测深仪振荡器有二种型式:①固定式:发射和接收振荡器直接在测船船壳底部开洞焊接安装;②携带式:发射和接收振荡器悬撑在船舷外侧没入水中。 在山区河流测量中,这两种型式都存在着无法克服的缺点:①在山区河流险滩测量时,礁丛水汊,比比皆是,振荡器随时均有擦礁撞碰之虞,振荡器表面常因擦磨损坏而无法使用,②在紊乱流态(如瀑水、漩水、急流)中测量,振荡器边缘会产生气泡而接
There are two types of echo sounder oscillators: ① fixed: the transmitter and receiver oscillators are directly welded to the bottom of the hull of the survey vessel for welding; ② the portable type: the transmitter and receiver oscillators are suspended from the water outside the ship’s side. In the mountain river measurement, both types of the existence of the insurmountable shortcomings: ① in the mountain river rapids, reefs Cong, abound, the oscillator at any time reef collision risk, the oscillator surface Often due to wiping damage can not be used, ② in turbulent flow (such as waterfalls, swirling water, rapids) measurement, the oscillator will have a bubble edge and then
