Underground water sampler with multiple sample storage functions

Abstract

The invention relates to the technical field of sample sampling, in particular to an underground water sampler with multiple sample storage functions. The underground water sampler comprises a circular plate, placing devices, a suction device, an extraction device and a cover sealing device; the upper end of the circular plate is connected with the plurality of placing devices which are uniformly distributed in the circumferential direction, a plurality of circular through holes are formed in the middle of the circular plate, and the suction device is installed at the upper end of the circular plate through a supporting rod. According to the underground water sampler, the problems that a plurality of samplers need to be prepared to avoid the mutual influence among the sampled samples when an existing sampler is used for sampling the underground water, so that the carrying difficulty of the sampler is increased, the use flexibility of the sampler is reduced and the like can be solved. According to the underground water sampler with the multiple sample storage functions, the suction device can be used for independently sampling the underground water at different sampling positions in a same device, so that the use flexibility of the device is improved, and the device is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of water resources, in particular to a groundwater sampler with multiple sample storage functions. Background technique [0002] Groundwater is an important part of water resources. Due to the stable water quantity and good water quality, it is one of the important water sources for agricultural irrigation, industrial mining and cities. Groundwater is rich in various minerals. When testing groundwater, it is necessary to first sample the groundwater , Groundwater sampling usually requires a sampler to take a sample. The sampler is a sampling device. The groundwater sampled by the sampler is then tested for its rich minerals by a testing agency. [0003] At present, existing sampler usually has the following deficiencies when sampling groundwater: 1. Existing samplers need to prepare multiple samplers in order to avoid mutual influence between samples when sampling groundwater. Multiple sampling processes ar...

Problems solved by technology

[0003] At present, existing sampler usually has the following deficiencies when sampling groundwater: 1. Existing samplers need to prepare multiple samplers in order to avoid mutual influence between samples when sampling groundwater. Multiple sampling processes are carried out on one sampling device, thereby increasing the difficulty of carrying the sampler and reducing the flexibility of the use of the sampler; 2. Some existing samplers cannot carry the sampled bottle when carrying it. The mouth of the bottle is pressed tightly, and the mouth of the sampling bottle is prone to drop and the sample is missing, which reduces the storage effect of the sampler
