Problems solved by technology

[0003] However, the existing sampling device 9 must pre-evacuate its sampling bottle 91, and before starting the sampling operation and after the sampling operation is completed, if the sampling bottle 91 cannot be sealed, the gas from the non-sampling site will flow in. Often cause inaccurate follow-up laboratory results
Furthermore, the existing sampling device 9 can only perform a single gas sampling action at a time and must return to the voyage, and cannot perform multiple sampling at the same place in a short period of time, or move to different places for multi-point sampling and then return to the voyage. Returning to the voyage not only has poor sampling efficiency, but also limits the sampling method and affects the accuracy of sampling result analysis

Abstract

An automatic sampling device and a sampling method are used for settling a problem of easy sampling data distortion of an existing device. The automatic sampling device according to the invention comprises the components of a body which is provided with a first end and a second end, wherein the body is provided with a plurality of channels which penetrate the first end and the second end of the body; a rotator which is connected with the body; and a front cover which is provided with at least one fluid inlet, wherein the front cover covers the first end of the body and is connected with the rotator.

Description

technical field [0001] The invention relates to an automatic sampling device and a sampling method, in particular to an automatic sampling device and a sampling method which can be assembled on an unmanned vehicle and transported by the unmanned vehicle to a predetermined location for sampling fluid samples. Background technique [0002] Please refer to figure 1 , it is a kind of existing sampling device 9 that can be assembled on unmanned vehicle, and this existing sampling device 9 has a sampling bottle 91, and its opening is provided with a control valve 911; Before sampling, this sampling bottle 91 The inside is in a vacuum negative pressure state. When the unmanned vehicle carried the existing sampling device 9 to a predetermined place, a power source 92 could be activated to drive a swing arm 93 to open the control valve 911, so that the gas on the spot could be fed by the sampling bottle 91 Inhaled by the vacuum negative pressure. After the gas sampling is complete...
