在我国大部分地区,冬季捕捞是湖泊水库及其它大水面渔业生产的重要环节。仅以镜泊湖水产养殖场为例,冰下捕鱼拉网作业已实现了机械化,进入八十年代初,冰下引网作业由于引进使用电动穿索器,从而在很大程度上降低了工时和劳动强度,缩短了网次时间,提高了工作效率。 目前,镜泊湖冬渔生产使用的这种穿索器,由于受到机械发电机和电力传输线的制约,每前行一次,都必须把电线从冰眼中全部拉出,既费时费力,电线又受冻脆裂容易折断,甚至短路,烧
In most parts of China, winter fishing is an important link in the production of lakes and reservoirs and other large-scale surface fisheries. Taking Jingpohu Aquaculture Farm as an example, fishing under the ice has been mechanized. In the early 1980s, the introduction of ice under the ice led to the use of electric rope traps, which greatly reduced the Working hours and labor intensity, shorten the network time, improve work efficiency. At present, this kind of rope-tracing device used for the production of winter and fisheries in Jingpo Lake has to be pulled out from the ice eyes every time because of the restriction of the mechanical generator and the power transmission line, which takes a lot of time and energy. Frozen brittle crack easily broken, or even short circuit, burn
