Problems solved by technology

[0003] The detection devices used at this stage usually sample groundwater at different depths and raise them to the surface for detection, which requires repeated operations many times. It is impossible to realize real-time sampling and detection of groundwater at a fixed depth, which is inefficient and very inconvenient

Abstract

The invention provides a sampling device for detecting the safety category of drinking water of underground water. The sampling device comprises a main controller, a fixing plate, a synchronous sampling device, a detection device and two sets of lifting devices symmetrically arranged on two sides of the top of the fixing plate; each set of lifting device drives one lifting plate to move up and down above a corresponding through groove; a synchronizing device comprises a top plate, a synchronizing plate and a bottom plate which is connected through a supporting plate; samplers are uniformly arranged along the height direction of the supporting plate, and each sampler comprises a piston rod and a sampling pipe; the detection device comprises a plurality of pH detection rods and a calcium ion sensor; a calcium ion sensor is arranged at the inlet of each sample introduction pipe; the plurality of pH detection rods are uniformly arranged along the height direction of the supporting plate; and the detection end of each pH detection rod is communicated with one sampling pipe; and detection values of the pH detection rods and the calcium ion sensors are transmitted to the main controller through wires. The sampling device can realize sampling detection of underground water samples with different depths, and is accurate in sampling and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a sampling device for detecting the safety category of groundwater drinking water. Background technique [0002] With the rapid development of the economy, the situation of groundwater pollution in my country is becoming more and more serious, and the water quality is deteriorating day by day. It has become a problem that cannot be ignored in the construction of regional ecological environment, watershed environment and water environment. In this situation, the protection and improvement of drinking water sources of groundwater has become an urgent task without delay. At this stage in our country, groundwater is the main component of drinking water sources. However, groundwater is also a water source that is easily polluted. It needs to be tested and evaluated to obtain water quality information and then carry out targeted purification treatment to meet drinking water sta...
