Sampling device for detecting water quality of construction base

Abstract

The invention discloses a sampling device for water quality detection of a construction base, and belongs to the technical field of water quality detection. Through combined arrangement of a heating agent, a water absorption rod, an autolysis sleeve shell, a driving heat conduction rod and the like, when a sampling barrel sinks, a sample injection pipe is in a blocked state, and after the sampling barrel sinks to a target depth, the sample injection pipe is automatically conducted, so that the sampling efficiency is improved; according to the water sampling device, water at a target depth can be accurately sampled, and the sealing cover can automatically block the sampling pipe after a certain water sample is obtained through the arrangement of the self-closing pipe assembly, so that the sampling pipe is in a blocked state in the sinking and pulling-back processes of the sampling barrel, the shallow water can be effectively prevented from entering the sampling barrel, and the sampling efficiency is improved. And through the arrangement of the completion reminding assembly, the completion reminding assembly can give out reminding to a worker when sampling is completed, so that the worker pulls back the sampling barrel in time, and the practicability is greatly improved.

Description

technical field [0001] The invention relates to the technical field of water quality detection, and more specifically relates to a sampling device for water quality detection of a construction base. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] During building construction, due to the generally long construction period, a construction base is usually built at the construction site for the construction personnel to live an...

Problems solved by technology

[0004] After the well is drilled, in order to ensure the health of the construction workers, it is usually necessary to test the water quality of the well water. During the test, a sampling device is required to sample the well water. In order to ensure the accuracy of the test, it is necessary to separate the well water at different depths. Sampling, but the sampling device of the prior art, when sampling the deep well water, the water in the upper shallow layer easily enters the sampling container, resulting in inaccurate sampling, which affects the accuracy of detection, and has poor practicability
