Embodiment Construction

[0021] The present invention will be specifically described below in conjunction with the accompanying drawings, such as Figure 1-4 shown, in this embodiment:

[0022] In this device, the device is powered by connecting with an external power supply, and the external power supply is connected to the power supply of the controller 2 , the air extraction electric telescopic rod 32 , the exhaust solenoid valve 40 , the sampling solenoid valve 42 and the exhaust electric telescopic rod 47 . The terminal is electrically connected to supply power. The model of controller 2 is a PLC controller of type FX1N-10MR / MT. The control signal output terminal of controller 2 is electrically connected to the signal access terminal of exhaust solenoid valve 40 and sampling solenoid valve 42. Connection, the control signal output end of the controller 2 is electrically connected to the air extraction electric telescopic rod 32 and the exhaust electric telescopic rod 47 through the relay, the bat...

Abstract

The invention discloses an air detection sampler. The air detection sampler comprises a base; a sliding support device is arranged on the base; a controller is arranged on the base; an automatic sampling box device is arranged on the base; an automatic adjustment sampling cylinder device is arranged on the automatic sampling box device; two sampling sleeves are in abutting joint, so that a sampling storage cylinder is formed; damage of a sampling bag due to an external reason is prevented; due to matching of an electric telescopic rod, an annular piston and the two sampling sleeves, the inner walls of the sampling sleeves can be cleaned through the annular piston rapidly and effectively, so that the cleanliness in the sampling sleeves is kept; an exhaust electric telescopic rod and an exhaust piston are matched; therefore, after sampling for one time is completed, residual gas in a sampling air pipe is discharged into an external environment through the exhaust piston; therefore, the air sampling precision is ensured; the error generated by sampling is reduced; and thus, air sampling is relatively precise. The air detection sampler in the invention has the benefits of being simple to operate and high in practicability.

Description

technical field [0001] The invention relates to the field of air detection and sampling related equipment, in particular to an air detection sampler. Background technique [0002] The air sampler is widely used in atmospheric environment monitoring, sanitation and epidemic prevention, labor protection, scientific research and other units, and can also be used in conjunction with related instruments. By analyzing the sampled gas, we can understand the degree of pollution of the environment by harmful gases, and provide the relevant authorities with the actual situation of pollution, so as to take countermeasures, so as to ensure that people have a healthy living environment. [0003] In the patent CN201811051171.1-an air detection sampler, the driving motor works to drive the piston to slide up and down, so as to sample the air in the required detection environment; a buffer device is provided, so that the piston and the inner side of the hollow cylinder are provided with a b...
