Field fixed-depth rapid water taking method

Abstract

The invention discloses a field fixed-depth rapid water taking method which comprises the steps of: S1, preparing a portable water taking device; S2, before taking water, inflating an airbag rubber plug through an inflation inlet so as to enable the airbag rubber plug to be pressed against a rubber water check, and keeping an inner cavity of a water taker body in an empty cavity state; S3, holdingon to a measurement rope, paying off the portable water taking device, and when the portable water taking device reaches a specified depth, pulling a pulling rope to deflate the airbag rubber plug, so that water at the specified depth rapidly inflows from a top water inlet and slowly inflows from a bottom water inlet, and enabling the water taker body to be continuously sunken; and S4, when the inner cavity of the water taker body is full filled with the water, blocking the bottom water inlet of the water taker body by a second cone of a lower blocking part, and blocking the top water inlet of the water taker body by an upper blocking part. An operator actively controls water intake of the device and adopts underground water at the specified depth; after water taking is completed, the water inlets and outlets are automatically blocked so as to ensure water taking quality and water taking efficiency at the specified depth; and the field fixed-depth rapid water taking method adopts manual control, does not adopt power and is particularly suitable for field water taking carrying.

Description

technical field [0001] The invention relates to the technical field of water body collection, in particular to a method for rapidly taking water at a fixed depth in the field. Background technique [0002] The existing water intake method has many limitations: 1) The closed control setting of the water intake device is poor, and water bodies at non-target depths are easy to mix in during the lowering of the device and the pulling up of the device. 2) The control of water in and out of the water intake device is complicated. When the device reaches the specified depth, it is often difficult to flexibly control the water in and out of the device, which reduces the efficiency of field water intake. 3) The cost of some electric water intake devices is high, the hazard of electric leakage is great, and the water intake in the field is inconvenient to carry. Contents of the invention [0003] In order to overcome the above-mentioned problems of the existing water intake methods...

Problems solved by technology

[0002] The existing water intake method has many limitations: 1) The closed control setting of the water intake device is poor, and water bodies at non-target depths are easy to mix in during the process of lowering the device and pulling the device up

2) The control of water in and out of the water intake device is complicated. When the device reaches the specified depth, it is often difficult to flexibly control the water in and out of the device, which reduces the efficiency of field water intake

3) The cost of some electric water intake devices is relatively high, the hazard of electric leakage is great, and it is inconvenient to carry water in the wild, etc.
