Embodiment 1

[0023] Example 1: The basic structure of the present invention is as figure 1 As shown, it consists of a holding straw 1, a storage module, a hydraulic motor 4 and a centrifugal pump 5.

[0024] The storage module is a container with a cavity, and the container has a filter element or a filter membrane to store the collected seabed microorganisms; the outer wall of the container has a hose inlet and a hose outlet, wherein the hose inlet is connected by the hose to hold the straw 1 , The outlet of the hose is connected to the inlet of the centrifugal pump 5 through the hose.

[0025] The hydraulic motor 4 is used to drive the centrifugal pump 5 to generate adsorption force at the holding straw 1 so as to suck the seabed microbial mat into the holding straw 1 and store the seabed microbial mat to the filter element or membrane of the storage module through a hose.

[0026] The storage module is installed on the side of the submersible sampling basket 7 through the fixing mechanism 6, a...

Embodiment 2

[0027] Example 2: Such as figure 2 Shown is a container-type storage module. The container-type storage module 2 consists of a rectangular parallelepiped container shell 2-4, multiple storage containers 2-7, sliding baffle 2-1, hose inlet 2-2 and hose outlet 2-3 ; The cuboid container shell 2-4 is a cuboid cavity with one end open, and the cuboid container shell 2-4 is placed vertically with the open end facing upwards. Two opposite sides are selected as the access surface, and the bottom end of one access surface is opened and a soft The tube interface is used as the hose inlet 2-2, which is opened at the top of the other access surface and fixedly connected with a hose interface as the hose outlet 2-3; the sliding baffle 2-1 is a rectangular plate hollowed out in the center, and the sliding block The plate 2-1 is uniformly opened with the same number of through holes as the above-mentioned storage container 2-7, the size of the sliding baffle 2-1 covers one end of the opening...

Embodiment 3

[0030] Example 3: Such as image 3 Shown is a submarine microbial mat sampler using a roll membrane storage module. The roll membrane storage module 3 consists of a cavity shell 3-1, a driving wheel 3-7, a driven wheel 3-2, a guide wheel 3-4, and a filter The membrane 3-3, the ratchet mechanism 3-9, the hose inlet 3-10 and the hose outlet 3-11 are composed; the cavity shell 3-1 is a hollow cylinder with two parallel faces perpendicular to the cylinder Placed on a horizontal plane, one of the parallel planes is open at the top and a hose interface is fixedly connected as hose inlet 3-10, and the other parallel plane is opened at the bottom and fixedly connected to a hose interface as hose outlet 3-11; Inside the cavity housing 3-1, below the position of the hose inlet 3-10, the driving wheel 3-7 is axially connected to two parallel surfaces, the driven wheel 3-2 is axially connected to the two parallel surfaces, the driving wheel 3-7 and The driven wheel 3-2 is separated by a ce...

Abstract

The invention discloses a seabed microbial mat sampler loaded on an ROV or a manned diving machine. A hydraulic motor is used for driving a centrifugal pump to adsorb a seabed microbial mat; seabed microbial mat samples can be collected and stored by storage modules in different forms; underwater multi-point sampling can be realized by switching or rolling a filter membrane by adopting a plurality of storage containers. The sampler consists of a sucking pipe, the storage modules, the hydraulic motor and the centrifugal pump, wherein each storage module is a container with a cavity; a filter core or a filter membrane is arranged inside the cavity of the container; the outer wall of the container is provided with a hose inlet and a hose outlet; the hose inlet is connected with a held sucking pipe by a hose; the hose outlet is connected with the inlet of the centrifugal pump by the hose; the hydraulic motor is connected with the centrifugal pump and is used for driving the centrifugal pump so as to generate an adsorbing force at the hose.

Description

Technical field [0001] The invention relates to a subsea microbial mat sampler, belonging to the field of deep-sea biological sampling tools. Background technique [0002] The deep sea is the largest genetic resource bank on earth. It is internationally recognized that the deep sea contains the richest species diversity and the largest biomass on earth. In recent years, the international community has generally attached importance to genetic resources in international seas. Both developed and developing countries have realized the significant potential application value of marine genetic resources outside their jurisdiction. [0003] Submarine microbial mats are clusters formed by a variety of colonies in the deep-sea environment, which appear as flocculent substances floating near the seabed, which are of great significance for marine biology research. However, the existing sampling tools such as water samplers and sediment samplers do not have the function of collecting submar...
