Problems solved by technology

Generally, the sampler has upper and lower openings. During the descending process of the sampler, some of the water entering from the lower port may accumulate at the corners of the sampler and not be discharged from the upper port in time, and the sampler has a certain length, so the collected The water sample is quite different from the water sample at the required depth
Moreover, the general samplers are all portable, and manpower cannot be liberated. The shaking of hands and other human factors will affect the water samples collected at the specified depth, resulting in low sampling accuracy.
The above deficiencies make it difficult for the current groundwater sampling to meet the needs of related research and investigation of groundwater

Embodiment 1

[0024] like Figure 1-Figure 5 It shows that the device includes triangular brackets 1. Rolling plate 2 and water recovery pipe 13. Among them, triangular bracket 1 is a active telescopic structure.It is divided into two parts of different diameter. The battery box and Weian Table 3 are installed on the rolling plate 2. The banded wire 4 and the pull rope 5 are wrapped in the small and large diameter of the rolling plate.Cover 6, the upper part of the water collection pipe 13 and the water inlet opening 6 are set with soluble oxygene probe 16, the cable 17 of the soluble oxygene probe 16 and the wire 4 of the wire 4, and the weight of the protective layer is added at the bottomIts support 8, the outlet 9 is located at the support 8 to avoid collision. The water collection pipe 13 has a wire protective cover 11, and the lower part of the water recovery pipe is equipped with a protective trunk 10.Essence

Abstract

The invention relates to a method and a device capable of measuring water level and in-situ dissolved oxygen and collecting underground water at different depths. A dissolved oxygen meter probe is combined with a water collection pipe for performing in-situ observation on dissolved oxygen in underground water at different depths, and the content of dissolved oxygen in a water sample transferred from the water collection pipe into a sampling bottle is prevented from being changed. An opening / closing state of a water inlet cover of the water collection pipe is controlled according to the difference of rope descending speeds on parts of different diameters on a reel. A three-legged support is fixed on an observation well, a valve of a water outlet of the water collection pipe is closed, and the water inlet cover of the water collection pipe is covered. The reel is rotated, so that the water collection pipe descends, and when a pointer of a microammeter deflects, a catch bolt is screwed, and then the water level of underground water is obtained; a switch of a battery box is switched off, the catch bolt is loosened, the reel is continuously rotated until the water inlet of the water collection pipe reaches specified depth, the catch bolt is screwed, and the content of dissolved oxygen is recorded; the water inlet cover is opened through a pull rope, and the reel is rotated to take out the water collection pipe after the water collection pipe is full of water. The device has the characteristics of simple operation, high efficiency, energy conservation, high accuracy, low cost and the like. The voltage of a used battery and the range of the microammeter can be adjusted according to the contaminated situation of underground water.

Description

Technical field [0001] The invention is the field of water mininger technology, which involves groundwater monitoring and collection technology. It is a method and device for measuring water levels, dissolving oxygen in situ, and collecting different deep groundwater. Background technique [0002] With the development of modern socio -economic and economic, water bodies such as lakes, rivers, and reservoirs are contaminated to varying degrees.According to the "UN World Water Resources Development Report (first edition)" (Abstract of execution), there are 2 × 10 every day 6 The tons of garbage is tilted into the water, including industrial, chemical, life and agricultural waste (fertilizers, pesticides, pesticides residues) and so on.With the intensification of the pollution of freshwater resources on the surface, the increase in industrial and domestic sewage discharge, and the influence of the large amount of pesticide fertilizers in agriculture, the problem of groundwater pollu...
