A pump-suction deep-sea biological collector

Abstract

The invention relates to a pumping type deep-sea organism collector which comprises a collecting cylinder. A seal is fixedly connected to one end of the collecting cylinder. The other end of the collecting cylinder is fixedly connected with a water pump support cylinder. A water pump propeller is disposed in the water pump support cylinder. A cable is connected to the periphery of the water pump support cylinder. A partition is disposed at the connection of the collecting cylinder and the water pump support cylinder. The seal is hinged to semi-circular doors symmetrically disposed in the collecting cylinder. An elastic device is further disposed between the seal and the semi-circular doors. The pumping type deep-sea organism collector has the advantages that the collector is simple in structure and simple to operate, strong siphon water flow can be generated through the water pump propeller, long-distance deep-sea movement and fast capturing of static organisms are realized effectively, fast opening and closing of the semi-circular doors are achieved through the spring, suction of organisms is achieved effectively by the hollow partition disposed at the connection of the water pump support cylinder and the collecting cylinder, the organisms can be prevented from being drawn into the water pump propeller and damage, and repeated capturing is achieved.

Description

technical field [0001] The invention relates to deep-sea collection equipment, in particular to a pump-suction deep-sea biological collector for a manned submersible. Background technique [0002] At present, when manned submersibles conduct scientific investigations in the deep sea, they can use manipulators to obtain static deep-sea creatures such as sea cucumbers and hydra. Compared with fish, which have the ability to move, it is difficult to capture them only by manipulators. Take the human submersible as an example. Because it is under deep sea pressure, the hydraulically driven manipulator moves slowly. Before the manipulator approaches the fish, the fish have already escaped. Therefore, it is urgent to design a device that can collect deep-sea creatures with movement capabilities. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has carried out research and improvement, and provides a pump-suction deep-sea biolo...
