Description

Running gear of in-pipe environment detection device

Technical Field

The invention belongs to the technical field of in-pipe environment detection, and particularly relates to a traveling mechanism of an in-pipe environment detection device.

Background

The environment detection is to design an environment detection network by utilizing a GIS technology, the information collected by the environment detection can be timely stored and displayed through the GIS, and the selected evaluation area is subjected to detailed site monitoring and analysis, the environmental protection is increasingly emphasized, the environment monitoring market is continuously expanded, the traditional environment monitoring station can not completely meet the social environment monitoring requirement, the country gradually opens a channel in the environment monitoring field, and a socialized environment detection mechanism with CMA environment detection qualification is taken as the vital force of third-party detection and becomes the first choice of the environment monitoring of the social entrusted property for professional environment monitoring,

the in-pipe environment detection device is a device for detecting water quality, gas and the like in a pipeline, for example, Chinese patent discloses a water quality treatment device for environment monitoring (patent number: CN201921163216.4), and the technical problem solved by the invention is that solid particles contained in a water body sink in the storage process of a water body sample, so that the water body generates a layering phenomenon, and the result of water quality detection is not practical easily. The existing method is to stir the water body by holding a stirring rod or achieve the effect of water body uniformity by shaking. Wherein carry out the in-process of stirring to the water through handheld puddler, the water body can be with air direct contact, including the stirring, makes the chemical reaction such as the material in the water body produces oxidation easily, and then influences the testing result. And carry out water homogeneous treatment through the mode of rocking, its operation process itself just is difficult to the accuse, rocks dynamics, rocks time etc. all more difficult control, and carries out water homogeneous mixing through the mode of rocking, and efficiency is extremely low, has very easily to mix the condition appearance that does not put in place. However, this patent has a disadvantage that it can only store the substance to be detected, that is, only take out the substance of the water body to be detected and detect it, and cannot detect the moisture at the point of use in time on site, because we know that the bacteria contained in the moisture will increase or decrease properly with the increase of time and the change of environment, and thus, the accuracy of the detected substance cannot be improved.

When it takes a sample to preserve simultaneously, do not install suitable running gear and be used for the mechanism that supports even intraductal, like this only can be through the sample back, put into this water of water quality processing apparatus for environmental monitoring again and deposit the pipe, the sample that will cause the sample like this carries out the secondary contact, thereby influence the detection structure, and its self does not set up good running gear simultaneously, be difficult for keeping its self stability like this in bent shape pipeline, then through the unable accurate control water of the even rabbling mechanism of water body deposit pipe about two parts surface of water highly uniform, then influence its sampling process and testing result.
