Abstract

The invention provides a handheld surface water sampling device which comprises an operating rod and a caisson, the operating rod mainly plays a role in controlling the sampling water depth, and the handheld surface water sampling device comprises a stainless steel telescopic rod, a grip, a deflector rod, a fixed pulley, a first reel, a second reel, a wire guide ring, a first nylon wire and a second nylon wire; the caisson is used for collecting a water sample and consists of a bracket, a filter screen, a sampling bottle, a rubber plug and an elastic sheet; the telescopic rod is detachably provided with a fishing line length meter used for measuring the length of the first nylon line. The sampling device provided by the invention can be used for collecting water samples with different water depths, is simple in sampling operation, and can be used for collecting water samples with high representativeness on the premise of guaranteeing the personal safety of operators; in addition, the device can effectively improve the sealing performance, can reduce the evaporation capacity of the water sample and can improve the experiment precision.

Description

technical field [0001] The invention relates to a sampling device in the field of hydrological experiments, in particular to a hand-held surface water sampling device. Background technique [0002] Water is an essential and precious resource for human production and life. Due to spatial differences in climate, altitude, latitude and longitude, and distance from the ocean, the distribution of water resources varies greatly between regions. In addition, the level of regional economic development is unbalanced, leading to differences in water pollution. It is precisely because of the existence of these problems that great challenges have been brought to the utilization of water resources and the improvement of the water environment. In-depth understanding of these hydrological laws and the mechanism of flow generation and confluence in river basins will inevitably involve sampling and research on water bodies such as rivers and lakes to analyze their internal laws. Most of th...
