Integrated device and method for sampling and separation and preparation of expansion link type pumping hose

Abstract

The invention provides an integrated device and method for sampling and separation and preparation of an expansion link type pumping hose. The device comprises a box body, a storage battery disposed in the box body, a micro vacuum pump, a micro peristaltic pump, a flow meter, a solenoid valve, a control panel, a hose runner, a expansion link detachably inserted into the box body, telescopic legs disposed at the bottom of the box body, a hose wound around the hose runner, a sampling head connected to a water intake end of the hose, and a water sample separation apparatus concerted with a wateroutlet end of the hose, the hose is supported by a lifting ring below the expansion link, the micro peristaltic pump, the flow meter and the solenoid valve are disposed on the hose, the storage battery and the control panel are connected with the micro vacuum pump, the micro peristaltic pump, the control panel, the flow meter and the solenoid valve, the micro peristaltic pump can pump the water atthe water intake end of the hose to the water sample separation apparatus, and the micro vacuum pump communicates with the water sample separation apparatus to provide a negative pressure environmentfor the water sample separation apparatus; and the device provided by the invention can realize a water sample collection and water sample separation integrated function and is suitable for water collection in both conventional and special environments.

Description

technical field [0001] The invention relates to the field of water body environment monitoring, in particular to a telescoping-rod type integrated equipment for sampling, separating and preparing a pumping hose. Background technique [0002] Water sample collection is an important part of water environment monitoring, and water sample collection equipment is an indispensable tool for water sample collection. Water sample collection equipment at home and abroad mainly includes fully automatic unmanned sampling equipment and manual sampling equipment. Unmanned sampling equipment is difficult to promote because of its high cost and maintenance costs; manual sampling equipment is currently mainly aimed at how to collect water at different depths. Water samples, and how to ensure the representativeness and diversity of water samples collected, but little attention has been paid to how to collect water samples from sampling points such as heavily polluted waters, remote waters, sh...

Problems solved by technology

[0008] In view of the above problems, the present invention proposes a telescopic rod-type pumping hose sampling and separation preparation integrated equipment. The length of rod and hose can be adjusted, the depth of buoy is fixed, the sampling head and water sample separation device have various functions, etc., which can realize the collection of water samples, sediment mixed samples and plankton water samples at different depths in different water areas, avoiding the existing The shortcomings of artificial sampling equipment in some waters, but also the on-site separation of water and sand and the quantitative pretreatment of plankton can be realized.
