Problems solved by technology

In recent years, life science research on deep-sea hydrothermal vents and cold spring vents has become a hot spot. At present, only platforms such as cable-controlled underwater robots and manned submersibles can reach the sampling points, and these platforms cannot carry out large-scale trawling operations. Therefore, current research on deep-sea Research on plankton and larvae has been slow

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] Such as figure 1 As shown, the suction plankton sampler includes a main body bracket, a power control unit, a water suction device and a filter collector. The main body bracket is a protective wall composed of bending rods and PP boards with light density and high strength. The core of the sampler is powered by a power-driven motor to drive the centrifugal blades to rotate and prevent biological escape backstop device 16-7 and flowmeter 13 water-absorbing devices, filter collectors composed of filter net clothes 15 and collection bottles 19; Combination block, embedded revolving door 5; said water absorbing device and filter collector are set on the protective plate of the main body bracket through the sampler suspension clamp 4.

[0029] The power control unit 2 is arranged on the isolation plate 8 on the fixed plate at the bottom of the support bracket to prevent...

Abstract

The invention discloses a deep-sea suction-type plankton sampler. The sampler is used for sampling planktons at different depths nearby a hydrothermal vent. The sampler comprises a body bracket, a water suction device and a filtering collector, wherein the body bracket supports a sampler body, the water suction device is composed of a power driven motor which drives centrifugal blades to rotate, aplankton escape prevention non-return device and a flowmeter, and the filtering collector is composed of a filter netting and a collection bottle. The deep-sea suction-type plankton sampler is smallin size, low in weight and applicable to various carrying instruments; fixed-point, fixed-time and quantitative plankton sampling through sit-on-bottom placement is realized, and the success rate of sampling is high; through the structural design of the water suction device, the situation that plankton bodies are damaged and contaminated during large-flow sampling can be effectively avoided; and aswitch is triggered to be started through underwater automatic control or a manipulator and other triggering mechanisms.

Description

technical field [0001] The invention relates to the field of marine biological sampling, in particular to a deep-sea suction type plankton sampler. Background technique [0002] Deep-sea biological research requires samples of plankton or benthic larvae. Obtaining plankton samples requires filtering a large number of water samples. At present, trawl sampling is mainly used, but trawling sampling can only complete plankton sampling in large areas of water, and is not suitable for fixed-point sampling. In recent years, life science research on deep-sea hydrothermal vents and cold spring vents has become a hot spot. At present, only platforms such as cable-controlled underwater robots and manned submersibles can reach the sampling points, and these platforms cannot carry out large-scale trawling operations. Therefore, current research on deep-sea Studies on plankton and larvae have been relatively slow. Deep-sea life science research urgently needs a plankton sampler that is ...
