Pre-detection device for environmental restoration

Abstract

The invention discloses a pre-detection device for environmental restoration, comprising a pre-measurement tube, wherein a thread groove is formed in an inner wall at an opening below the pre-measurement tube, a first thread sleeve is meshed on an outer surface wall of the thread groove through threads, the first thread sleeve is fixedly sleeved on an outer wall of an opening at a top end of a sampling branch tube, a storage chamber is formed in the pre-measurement tube, a sample chamber is formed in the sampling branch tube, the storage chamber communicates with the sample chamber, in the pre-detection device for environmental restoration disclosed by the invention, the pre-measurement tube and the sampling branch tube are in threaded split connection with each other, the sampling branchtube is separated from the pre-measurement tube by using a moving push rod, so that the sampling branch tube directly samples, stores and detects a water sample, thereby avoiding sample pollution caused by repeated transfer of the water sample during sampling and detection and ensuring the detection quality, and the device not only can play the role of a test tube, but also can perform sampling and storage, is simple and convenient to operate and meets the needs of use.

Description

technical field [0001] The invention relates to the field of environmental restoration detection products, in particular to a pre-detection device for environmental restoration. Background technique [0002] With economic development and urban construction speeding up, people's living environment is changing, among which many enterprises or production and business units will be relocated in the adjustment of urban industrial structure and layout, and the nature of original land use will change, such as real estate Development and other construction, soil pollution causes water pollution, the risk of harm to the surrounding environment and human health, in order to protect the lives of the people and maintain normal production and construction activities, prevent environmental pollution accidents, and assess the health risk of water resources in polluted sites And restoration has become more and more important and urgent, so it is necessary to carry out pre-inspection for env...

Problems solved by technology

[0002] With economic development and urban construction speeding up, people's living environment is changing, among which many enterprises or production and business units will be relocated in the adjustment of urban industrial structure and layout, and the nature of original land use will change, such as real estate Development and other construction, soil pollution causes water pollution, the risk of harm to the surrounding environment and human health, in order to protect the lives of the people and maintain normal production and construction activities, prevent environmental pollution accidents, and assess the health risk of water resources in polluted sites and restoration has become more and more important and urgent, so it is necessary to carry out pre-inspection for environmental restoration, and the detection equipment is an important equipment for pre-inspection, but the current pre-inspection equipment has some shortcomings in the process of use

[0003] At present, test tubes for testing play a key role as the main equipment for pre-testing, but the current test tubes for testing cannot directly sample water samples. It can be tested, but contamination may occur during the sample transfer process, which will affect the test results and cannot meet the needs of use
