Description

Water sample monitoring and collecting device

Technical Field

The utility model relates to a collecting device, in particular to a water sample monitoring and collecting device.

Background

The water sample monitoring refers to the monitoring of physical properties, metal compounds, non-metal inorganic substances, organic compounds, biological monitoring, hydrological and meteorological parameters and substrate monitoring of environmental water and water pollution sources.

Before water sample collection, a water container and a sampler which are made of suitable materials are selected according to the properties of monitoring items and the requirements of a sampling method, and the water container and the sampler are cleaned. In addition, the vehicle must be ready. Vehicles often use watercraft. The sampling device is made of materials with stable chemical properties, proper size and shape, does not adsorb components to be detected, is easy to clean and can be used repeatedly.

Sampling in rivers, lakes, reservoirs and oceans, frequently taking vehicles such as monitoring boats or sampling boats, hand-rowing boats and the like to collect samples, and collecting samples in a wading way on a bridge. When collecting surface water sample, it can be directly collected by using proper container, such as plastic tube. When the deep water sample is collected, a simple water sampler, a deep water sampler, a water sampling pump, an automatic water sampler and the like can be used.

Water pump equipment is often utilized to collect water samples from monitoring wells. After the water sampling device is started, water is discharged for a plurality of minutes, the old water accumulated in the pipeline is discharged, and then a sampling container (which is cleaned in advance) is used for receiving a water sample. For wells without pumping equipment, a suitable water sampler can be selected for collecting water samples, such as a deep water sampler, an automatic water sampler and the like. For self-fountain water, sampling is directly carried out at a water gushing port. Sampling the non-self-fountain water by a method for collecting a well water sample. For tap water, a tap is completely opened, and old water accumulated in a pipeline is discharged and then sampled.

Current water sample collection system structure is complicated, is not convenient for sample fast, is used for gathering surface layer water and deep water simultaneously and needs to adopt different devices, when gathering surface layer water, if directly take with the plastic cylinder, the easy risk of turning over that takes place is not convenient for use for a long time.
