Self-insertion type marine environment sampling device capable of vertically sampling

Abstract

The invention discloses a self-inserting type marine environment sampling device capable of vertically sampling, which comprises a supporting bottom plate, a sampling pipe is fixedly connected to the center of the top end of the supporting bottom plate, a sampling piston is connected to the bottom end in the sampling pipe in a penetrating manner, and the bottom end of the sampling pipe penetrates through the supporting bottom plate and is in flange connection with a sampling lantern ring; a pull rod is fixedly connected to the center of the top end of the sampling piston, penetrates through the supporting bottom plate and is fixedly connected with a supporting cross beam, and fixed vertical plates are fixedly connected to the two sides of the center of the top end of the supporting bottom plate. According to the invention, a first transverse plate is bounced to move upwards through deformation recovery of a supporting spring, so that two fixed supporting plates are pushed to move upwards, the supporting cross beam moves upwards, the sampling piston is pulled to move upwards, seawater enters the sampling pipe from the sampling lantern ring, and the supporting spring rebounds to support the device to complete extraction of an ocean sample; and as manual extraction is not needed in the operation process of the device, the requirement on the working intensity of operators is greatly reduced.

Description

technical field [0001] The invention relates to the field of environmental sampling, in particular to a self-inserting marine environment sampling device capable of vertical sampling. Background technique [0002] Sampling refers to the process of taking individuals or samples from the population. Sampling is divided into two types: random sampling and non-random sampling. Marine environment sampling is to take part of the water body in the ocean and carry it to the laboratory to be tested for testing. , in order to detect the water quality of the ocean water body, so as to obtain the basic data of the physical, chemical and biological parameters in the ocean. [0003] Environmental sampling devices on the market today: [0004] (1) In the process of environmental sampling, it is often necessary to manually pull the sampling tube to extract seawater in the ocean. When multiple seawater samples need to be taken in the same area, the operator needs to manually operate many ti...
