Embodiment 1

[0023] Embodiment 1: the basic structure of the present invention is as figure 1 As shown, it consists of a holding suction pipe 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 for storing the collected seabed microorganisms; the outer wall of the container has a hose inlet and a hose outlet, wherein the hose inlet is connected to the holding straw 1 through a hose , the outlet of the hose is connected to the inlet of the centrifugal pump 5 through a hose.

[0025] The hydraulic motor 4 is used to drive the centrifugal pump 5 to generate adsorption force at the suction pipe 1, thereby sucking the seabed microbial mat into the holding pipe 1, and storing the seabed microbial mat to the filter element or filter membrane of the storage module through the hose.

[0026] The storage module is installed on the side of the submersible sampling bask...

Embodiment 2

[0027] Embodiment 2: as figure 2 Shown is a container storage module, a container storage module 2 consisting of a cuboid container housing 2-4, a plurality of storage containers 2-7, a sliding baffle 2-1, a hose inlet 2-2 and a hose outlet 2-3 ; The cuboid container shell 2-4 is a cuboid cavity with an open end, and the cuboid container shell 2-4 is placed vertically upwards with its open end, and its two opposite sides are selected as the access surface, and the bottom end of an access surface is open and connected with a soft The pipe interface is used as the hose inlet 2-2, and is opened on the top of the other access surface and is 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 baffle The plate 2-1 is evenly opened with the same number of through holes as the above-mentioned storage container 2-7, and the size of the sliding baffle 2-1 covers one end of the opening ...

Embodiment 3

[0030] Embodiment 3: as image 3Shown is a seabed microbial mat sampler that adopts a roll film storage module, the roll film storage module 3 is composed of a cavity housing 3-1, a driving wheel 3-7, a driven wheel 3-2, a guide wheel 3-4, a filter Membrane 3-3, ratchet mechanism 3-9, hose inlet 3-10 and hose outlet 3-11; cavity housing 3-1 is a cylinder with a hollow inside, and the two parallel planes of the cylinder are vertical Placed on a horizontal plane, one of the parallel planes has an opening at the top and is fixedly connected with a hose interface as the hose inlet 3-10, and an opening at the bottom of the other parallel plane and is fixedly connected with a hose interface as the 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 two parallel surfaces, and the driving wheel 3-7 and There is a certain distance be...

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 seabed microbial mat sampler, which belongs to the field of deep sea biological sampling tools. Background technique [0002] The deep ocean 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 sea areas. Both developed and developing countries have recognized the significant potential applications of marine genetic resources beyond their jurisdiction. [0003] Submarine microbial mats are clusters formed by various bacterial colonies in the deep sea environment, which appear as flocculent substances floating near the seabed, and are of great significance to marine biology research. However, currently existing sampling tools such as water body samplers and sediment samplers do not have the fu...
