A fishing device includes a fishing cage, a lifting mechanism for raising and lowering the fishing cage in water, a fish inlet arranged on the fishing cage, a gate at the fish inlet and a floating body connected with the gate, which drives the gate to close the fish inlet when the floating body sinks, and can drive the gate to open the fish inlet when the floating body floats. The invention also provides a fishing method, in which the fishing cage is placed in the water, and the fishing cage is floated in the water by a lifting mechanism or a floating body. When the floating body floats, the gate is driven to open the entrance on the fishing cage for fishing operation; when the lifting cage leaves the water surface, the floating body on the fishing cage loses its buoyancy and sinks, the gate closes the entrance to realize the fishing entry with this structure. The automatic opening and closing of fish mouth can save manpower significantly in the whole fishing operation, and has simple structure and environmental protection in the operation process. Fixed-point centralized fishing can be realized by setting large-scale fishing devices and vertical limit rods matching fishing devices in the fixed-point sea area.
【技术实现步骤摘要】
一种捕鱼装置及方法
本专利技术涉及捕鱼领域,尤其是一种捕鱼装置及方法。
技术介绍
目前在捕鱼领域,特别是海洋捕鱼,常用拉网的方式进行,该方式所需人力成本高,工作环境较差,拉网捕鱼对海底生态产生严重的破坏,且在拖拽渔网过程中对鱼的伤害大,容易发生死鱼现象,另外,无法实现定点、大规模的集中捕鱼作业。
技术实现思路
本专利技术目的是提供一种能有效解决上述问题的捕鱼装置及方法,为达到上述目的,本专利技术采用如下技术方案:一种捕鱼装置,包括捕鱼笼、用于使捕鱼笼在水中升降的提升机构、设在捕鱼笼上的进鱼口、设在进鱼口处的闸门和与闸门连接的浮体,浮体下沉时能带动闸门关闭进鱼口,浮体上浮时能带动闸门打开进鱼口。进一步的,所述提升机构为气囊或提升机械手。进一步的,所述捕鱼笼的顶部开口,所述捕鱼笼包括底网和侧网,所述底网倾斜设置,所述底网的下端与侧网相交处形成卸鱼口。进一步的,所述气囊设置在所述捕鱼笼底部,所述进鱼口设在所述捕鱼笼的侧面,所述闸门铰接在捕鱼笼的进鱼口处的上方。进一步的,所述气囊设置在所述捕鱼笼底部,所述捕鱼笼的侧面设有多个呈竖直分布的进鱼口,每个进鱼口处设有闸门,所述闸门铰 ...
