Hydrological detection instrument device

Abstract

According to a hydrological detection instrument device, the interior of a first sampling pipe is divided into a sampling cavity and a transmission cavity, a first piston is arranged in the sampling cavity, and a fixing plate is arranged in the transmission cavity; a first sampling opening is formed in the bottom end of the side wall of the first sampling pipe and is positioned below the first piston; a second piston is arranged in the second sampling tube, and the top of the second sampling tube is fixedly connected with the bottom of the first sampling tube through a supporting rod; a second sampling opening is formed in the bottom end of the side wall of the second sampling pipe; the top of the connecting rod is arranged in the transmission cavity, penetrates through the fixing plate and is rotationally connected with the fixing plate. The bottom of the connecting rod sequentially penetrates through the first sampling tube and the second sampling tube and is fixedly connected with the first piston and the second piston; the transmission assembly is arranged in the transmission cavity, connected with the connecting rod and drives the connecting rod to move up and down. The detection instrument device is convenient to detect and accurate in detection result.

Description

technical field [0001] The invention relates to the technical field of hydrological detection, and more specifically relates to a hydrological detection instrument device. Background technique [0002] Hydrological detection usually monitors hydrological parameters such as rivers, lakes, reservoirs, channels, and groundwater. The monitoring content includes: water level, flow, flow velocity, rainfall, evaporation, sediment, ice, moisture, water quality, etc. [0003] In order to understand the substances contained in the water, it is usually necessary to detect the water quality of the water. At present, when the water quality is tested, the water sample is usually collected by a hydrological detector, and then tested, but the existing detection devices are usually It is only sampling and testing the water body at a specific depth, and the results of water quality testing are not accurate enough. [0004] Therefore, it is an urgent problem for those skilled in the art to de...
