The invention discloses a multifunctional acquisition device for survey of fishery resources in the technical field of fishery equipment. The multifunctional acquisition device comprises a controller and a shell, a camera is installed on the shell and electrically connected with the controller. A plurality of first cavities are formed in the top wall of the shell, pressure measuring rods are detachably connected to the bottoms of the first cavities, and the pressure measuring rods in different first cavities are different in compressive strength; the end, away from the bottom of the first cavity, of the pressure measuring rod is fixedly connected with a pressing plate which is in vertical sliding fit with the inner side wall of the first cavity. A sampler is arranged above the first cavity, a plurality of connecting rods are detachably connected to the bottom of the sampler, and the ends, away from the sampler, of the connecting rods are detachably connected with the outer top wall of the shell; based on different water pressures at different water depths, the pressure measuring rods are broken by using different water pressures to generate a negative pressure effect, and the different pressure measuring rods are broken so as to sample water at different water depths by using negative pressure; according to the benthic organism sampling device, benthic organism samples can be screened in the benthic organism sampling process, and the operation time is saved.
本发明公开了渔业设备技术领域的一种渔业资源调查用多功能采集装置,包括控制器和壳体;壳体上安装有摄像头,摄像头与控制器电连接;壳体顶壁内开有若干第一腔,第一腔底部均可拆卸连接有测压杆,不同第一腔内的测压杆抗压强度不同;测压杆远离第一腔底部的一端固定连接有压板,压板与第一腔内侧壁竖向滑动配合;第一腔上方设有取样器,取样器底部可拆卸连接有若干连杆,连杆远离取样器的一端与壳体外顶壁可拆卸连接;本发明基于不同水深的水压不同,利用不同的水压将测压杆断裂产生负压效果,不同的测压杆断裂进而利用负压对不同水深的水进行取样;本发明在对底栖生物取样的过程中即可对底栖生物样品进行筛选,节约操作时间。
