Self-suction type large-flow biological pump device based on magnetic driving and method of device

Abstract

The invention discloses a self-suction type large-flow biological pump device based on magnetic drive and a method of the device, the device comprises a control power supply, a sampling pump, a protective support and a settling assembly, and the control power supply, the sampling pump and the sedimentation assembly are all fixed on the protective support; the sampling pump comprises an external pipeline, a flow guide cover shell, a multi-pole stator and a hollow rotor; external fluid can be sucked into a working driving cavity through a water inlet groove opening of an intercepting piece by the rotating spiral blade, flows out of the outlet jet flow of the working driving cavity to form negative pressure, and is driven to enter a hollow cavity of the flow guide cover shell from an externalpipeline; the settling assembly comprises a buffer pipeline, a cylindrical filter screen and a settling bottle which are connected in sequence; and a hollow motor is connected with a control power supply for providing electric power through a circuit. The device is small in size and compact in structure, can be carried on other large-scale equipment to independently filter organisms in a water body, and can also be used for locking a self-absorption sample by a manipulator or other equipment with an organism tracking function.

Description

technical field [0001] The invention belongs to the technical field of marine biological sampling, and in particular relates to a self-priming large-flow biological pump device based on magnetic drive and a method thereof. Background technique [0002] The unique chemosynthetic biological community is bred near the cold spring mouth of the seabed hydrothermal vent, which is rich in biological gene resources and is a natural gene treasure house. Because of its extremely special environment, which is very similar to the environment of the early earth, it is considered a "laboratory" for cutting-edge scientific research such as the origin of life. Most of the large organisms in these communities are invertebrates, and the larvae of invertebrates are planktonic larvae. Therefore, obtaining larvae of hydrothermal or cold seep organisms is one of the important ways for deep-sea life science research. [0003] Due to the complex micro-topographic environment of the seabed hydrothe...

Problems solved by technology

However, this technology uses a centrifugal pump to drive a large volume of water for filtration, and the high-speed rotating blades during sampling will cause greater damage to the fragile invertebrate larvae, easily breaking biological samples, resulting in inaccurate survey data; in addition, the sampling The filter adopts a straight line pipeline, which is easy to cause damage to the mesh port and extrusion of biological samples when filtering with large water flow
