[0002] Surface water is formed by the accumulation of natural precipitation and snow over the years and naturally drains to the ocean or disappears through evaporation and seeps into the ground. Although the natural source of water in any surface water system is only the precipitation in the catchment area, there are many other factors that affect the total amount of water in the system. These factors include the storage capacity of lakes, wetlands, reservoirs, the permeability of the soil, and the characteristics of surface runoff in the catchment area.

One end outside the U-shaped plate is fixedly connected; an L-shaped plate, the L-shaped plate is fixedly mounted on the top of the bottom plate; a fixed pulley, the fixed pulley is fixedly mounted on the outer wall of the L-shaped plate away from the U-shaped plate; a wire rope, the wire rope is wound on the winding wheel, and the bottom end of the wire rope extends to the bottom of the fixed pulley and is slidably connected to the fixed pulley; a sampling bucket, the sampling bucket is fixedly mounted on the bottom end of the wire rope; an electric push rod, the electric push rod is fixedly mounted on the top inner wall of the sampling bucket. The above patent has the following shortcomings: although the patent can collect river water, it can only sample one sample of water at a time, and in order to ensure the number of experimental samples, multiple reciprocating sampling is required, so the sampling efficiency needs to be improved. In view of this, we propose a surface water sampling device. Utility Model Content
