A water sampling device

Abstract

The present invention relates to the field of water quality sampling equipment, particularly to a water quality sampling apparatus, which comprises a housing, a control unit, an indication unit, a vacuum pump, a sampling unit, a heating unit and a rainwater collection unit, wherein the control unit and the indication unit are arranged on the housing, the vacuum pump is electrically connected to the control unit, the sampling unit is arranged below the housing, the sampling unit comprises a vacuum sampling bottle, the sampling unit is used for performing automatic timing sampling on water to be sampled, the heating unit is connected to the sampling unit and is used for heating the sampling unit, and the rainwater collection unit is positioned on the upper portion of the housing, is controlled by the control unit, and is used for automatically collecting rainwater. With the water quality sampling apparatus of the present invention, the polluted water can be subjected to timing sampling, and the local rainwater can be collected so as to increase the polluted water area environment detection date; and the sampled water is subjected to thermal insulation storage with the sampling bottle, such that the water quality situation of the water to be sampled during the sampling can be truly reflected.

Description

technical field [0001] The invention relates to the field of water quality sampling equipment, in particular to a water quality sampling device. Background technique [0002] With the rapid development of social economy, the problem of environmental pollution is becoming more and more prominent, especially the problem of water environment pollution is showing the trend of regional expansion, pollution diversification and serious degree. In the face of global environmental problems and the increasingly severe water crisis, water resource protection has become an urgent problem facing human beings. In order to strengthen the monitoring of water environment quality, grasp the current situation of water quality in a timely manner, determine the temporal and spatial distribution of pollutants in water bodies, and then trace the source of pollutants, pollution channels and their impact on human health, a large number of on-site water quality sampling work is required. , in order ...

Problems solved by technology

[0004] 1. Although some automatic water quality sampling devices have the function of heat preservation and heat insulation for the water quality after sampling, the heat preservation structure is relatively complicated and the production cost is high, which is not conducive to popularization

[0005] 2. Some automatic water quality sampling devices cannot clean the water inlet pipe, especially the part of the water inlet pipe located in the water is easy to adhere to a large number of microorganisms, and a large number of microorganisms are sucked into the sampling bottle, resulting in inaccurate sampling

[0006] 3. In a low temperature environment, the water surface of the water to be sampled is easy to freeze, and the water inlet pipe extending into the water to be sampled will be blocked by the ice inside it, resulting in the failure of normal water quality sampling

[0007] For heavily polluted waters, in addition to sampling the surface water quality, the staff will also collect and sample the rainwater in the waters to improve the water quality data of the polluted waters and provide data reference for further pollution control. However, manual collection of rainwater is often There will be difficulties in collecting rainwater or unrepresentative rainwater collection points, which will distort the water quality testing data
