Sampling device for underground water in deep well

Abstract

The invention discloses a sampling device for underground water in a deep well. The sampling device for the underground water in the deep well mainly comprises a sampling bottle, a sampling cover, a water inlet buckle, a sampling rope, a sample storing cover, a supporting rod and a water inlet, wherein the sampling rope is fixedly connected with the sampling cover together at the center of the outer surface of the top end of the sampling cover; the water inlet buckle is attached to the inner surface of the bottom end of the sampling bottle; one vertex point of the water inlet buckle is fixedly connected with the sampling bottle at the center of the inner surface of the sampling bottle by a hinge; a water inlet is attached to the bottom of the sampling bottle; one vertex point of the water inlet is located at the center of the inner surface of the bottom of the sampling bottle and can be completely covered with the water inlet buckle at the lower part of the water inlet buckle; the supporting rod is fixedly connected with the water storing cover together at the center of the inner surface of the top end of the sample storing cover; during sampling, the sampling cover is fixedly connected with the sampling bottle together; after the sampling is ended, the sample storing cover is fixedly connected with the sample storing bottle together. The device is simple in structure and convenient to operate; the sampling efficiency of underground water can be improved, and convenience can be provided for sampling underground water.

Description

Technical field [0001] The invention relates to the technical field of samplers, more specifically a device for sampling deep well groundwater. Background technique [0002] With the exposure of various groundwater pollution problems, there are more and more researches on groundwater quality. To study groundwater, we must first obtain groundwater. One way to obtain water samples is to take water samples through boreholes. The boreholes are usually small in diameter and there are many inconveniences when sampling. The usual sampling method is to use fixed-depth samplers or in the borehole Pump directly with a pump. However, sometimes due to various external conditions, the pumping conditions are not available, and other sampling devices need to be used instead. At the same time, the common sampling equipment is large in size and poor in flexibility. Therefore, a device for deep-well groundwater sampling is designed with simple structure and convenient operation, which improves t...
