AI Technical Summary

Technical Problem

When performing liquid sampling operations, some liquid sampling conditions are harsh, and staff cannot directly contact the liquid, and existing liquid sampling devices are difficult to avoid the damage caused by liquid to personnel.

Method used

A liquid sampling device is designed, including a columnar frame extending vertically, a float and sampling assembly located within the frame, and a chain connected between the float and sampling assembly. The sampling assembly includes a sampling cavity fixed in the frame, a piston cavity located above the sampling cavity and a pull rod extending vertically. Through the cooperation of the float and the chain, the sampling assembly can be self-sampled in the liquid.

Benefits of technology

The self-sampling of the sampling assembly in the liquid is realized, reducing unnecessary personnel operations and avoiding the damage of the liquid to personnel.

Abstract

The invention discloses a liquid sampling device. The liquid sampling device comprises a columnar frame, a buoy, a sampling assembly and a chain, wherein the columnar frame extends along the vertical direction; the buoy and the sampling assembly are positioned in the frame; the sampling assembly comprises a sampling cavity fixedly held in the frame, a piston cavity located above the sampling cavity and a pull rod extending in the vertical direction, the sampling cavity is provided with a liquid inlet located in the top, the liquid inlet is communicated with the sampling cavity and the piston cavity, the lower portion of the pull rod is located in the piston cavity and abuts against the liquid inlet, and the lower portion of the pull rod is located in the piston cavity and abuts against the liquid inlet. The upper portion of the pull rod is exposed out of the top of the piston cavity and connected to the chain. After the liquid sampling device is immersed into liquid, the buoy floats on the surface of the liquid, and the buoy stretches the pull rod through the chain, so that the lower part of the pull rod is separated from the liquid inlet; therefore, automatic sampling of the sampling assembly in the liquid is realized, unnecessary personnel operation is reduced, and injury of the liquid to personnel is avoided.
