Embodiment Construction

[0024] Attached below Figure 1-4 A suction type water sample collector and unit suction type bottom water sample collection system of the present invention will be described in detail below.

[0025] as attached figure 1 , 2 As shown, a suction-type water sample collector 1 includes a water sample cup 8, a sealing gasket 9, a collector seat 10, a bolt 11, a collector cover 12, a valve stem 13, a spring 14, a round nut 15, and a pressing pad 16. Diaphragm 17, sealing ring 18, valve seat 19, said diaphragm 17 is compressed between collector seat 10 and collector cover 12 to form upper and lower cavities, and the upper chamber is connected to water through the through hole of collector cover 12. The sample collection area communicates, and the lower cavity communicates with the water sample cup 8 screwed on the collector seat 10 through the water inlet hole on the collector seat 10, and a sealing gasket 9 is arranged between the water sample cup 8 and the collector seat 10, an...

Abstract

The invention provides a suction type water sampler and a unit suction type underlying water sampling system, belonging to the technical field of marine monitoring. A main mechanism of the water sampling system is the suction type water sampler; the suction type water sampler comprises a water sample cup, a sampler seat, a sampler cover, a valve rod, a spring, a diaphragm and a valve seat, wherein the diaphragm is pressed between the sampler seat and the sampler cover, so that an upper cavity and a lower cavity are formed; the upper cavity is communicated with a water sampling area by means of a through hole formed in the sampler cover; the lower cavity is communicated with, by means of a water inlet hole formed in the sampler seat, the water sample cup screwed down on the sampler seat, and is communicated with the water sampling area by means of a controllable gap between the valve rod and the valve seat; the valve rod sequentially passes through the sampler cover, the diaphragm, the sampler seat and the valve seat from top to bottom; a spring is installed between the upper end of the valve rod and the sampler cover, and the valve seat is sealed by using the spring to press the valve rod; the valve rod and the diaphragm are pulled to move upwards, the air in the water sample cup is sucked into the lower cavity, and the water in the water sampling area is sucked into the water sample cup, so that water sampling is completed. The suction type water sampler and the unit suction type underlying water sampling system avoid the problem that water samples are easily confused, expand the sampling range of the water samples, and improve the sampling quality of the underlying water samples.

Description

technical field [0001] The invention relates to a marine monitoring technology, in particular to a suction type water sample collector and a unit suction type bottom water sample collection system. Background technique [0002] Existing sea bottom water sampling equipment mainly contains pull-type simple water sampling device, knock-off type water sampling device, card cover type water sampling device and pump type water sampling device. [0003] The pull-type simple water collector is a simple water collector. The sampling bottle is settled to the required depth, and the stopper is opened by lifting the rope. After the water is filled with the sampling bottle, the sampling is completed. It has a simple structure and is easy to carry, but It cannot automatically and regularly sample, the efficiency is low, and it is not suitable for deep water sampling. [0004] Both the knock-off type water collector and the cap-type water collector settle the sampling bottle to the requir...
