Special acquisition box for sampling gas and liquid

Abstract

The invention relates to an acquisition box, in particular to a special acquisition box for sampling gas and liquid. The special acquisition box comprises an acquisition box body and an air pump, wherein a plurality of valves capable of being controlled to open and close are installed on a vertical wall of the acquisition box body with good air tightness, and each valve can be connected with a sampling opening of a sampling bag through a conduit; one air pump is fixedly installed inside the acquisition box body, the connection between the air pump and an air pump power supply is controlled by a remote control assembly, and an exhaust opening of the air pump is connected with an open environment outside the acquisition box body through the conduit and the valves. When the special acquisition box is used, the air pump is remotely controlled to be powered on, the air inside the acquisition box body is discharged to form a negative pressure environment, and gas and liquid samples outside the acquisition box body are sucked into the sampling bag so as to complete the sampling. According to the special acquisition box for sampling the gas and liquid, the accuracy in sampling and working efficiency can be improved, the leakage of toxic and harmful matters can be effectively prevented when the special acquisition box is used in high-altitude sampling operation and in the toxic and harmful environment, and the secondary pollution and harm on the life and health of the working personnel can be avoided.

Description

technical field [0001] The invention relates to a collection box, in particular to a collection box specially used for gas and liquid sampling. Background technique [0002] At present, with the deterioration of the living environment of human beings, the monitoring and detection of the environment has become an important measure to protect the environment. However, due to the limitations of objective conditions, how to quickly, timely and accurately obtain test samples has become a practical problem for effective environmental monitoring and testing, and it is also a difficult problem for effectively combating environmental crimes. With the rapid development of remote-controlled unmanned aerial vehicles, using remote-controlled unmanned aerial vehicles as a carrier and carrying a collection box specially used for gas and liquid sampling can completely change the working mode of on-site sampling in the past. The main advantages are as follows: One is to improve the accuracy...
