Description

A Portable Pressure Water Sample Collector

technical field

The utility model relates to the technical field of water sample collection devices, in particular to a portable pressure water sample collection device.

Background technique

The collection, testing and analysis of water samples is an important means to study water bodies and observe water quality and changes. According to the layout principles of surface water monitoring points in "Water and Wastewater Monitoring and Analysis Methods (Fourth Edition)", water sample collection should be determined according to the depth of the water body. When the water depth reaches a certain level, in addition to collecting surface water samples, it is also necessary to collect water samples at a certain depth underwater. At present, our country basically relies on manual approach and boating to collect surface water, or use simple gravity-into-water sampling equipment. However, in most cases, only surface water can be collected, the sampling depth is not clear, and the water volume is small, which greatly limits the scope of water sample collection, reduces the representativeness of water samples, and leads to the fact that the experimental results cannot fully reflect the real water quality. Secondly, the lack of equipment such as field power supplies limits the use of power-consuming samplers such as water pumps. Therefore, it is necessary to develop a new type of collector for collecting water samples in the field to ensure representativeness of water quantity and quality. Our country already has SC-01 deep water sampler, BC-2300 portable automatic water quality sampler, etc.; the German HYDRO-BIOS company has produced Ruttner type, Universal type manual water sample collector and ulti-Limnos model automatic water sample collection in addition, there are synthetic bucket samplers made by other companies.

There are technical problems such as limited power supply for field sampling, small sampling range, unclear depth, insufficient sampling volume, damage to the surrounding ecological environment, and waste of human and financial resources. Existing water samplers, such as the Universal manual water sampler and the Multi-Limnos automatic water sampler, are inconvenient to take deep water samples and cannot observe the sampling depth in real time. The electric sampler series is limited by the external power supply conditions. The mechanical sampler has a large operating range and seriously damages the ecological environment. Some sampling points are not convenient for large machines to reach, and the representativeness of water samples cannot be guaranteed under the premise of consuming a lot of manpower and financial resources, which affects the experiment. accuracy.
