Filtering device for hydrological water quality detection

Abstract

The invention discloses a filtering device for hydrological water quality detection. The filtering device comprises a filtering mechanism and a water sampling mechanism; the filtering mechanism comprises a lower top disc, a butt joint ring provided with an external thread, and a coarse filtering barrel, a first-stage fine filtering barrel and a second-stage fine filtering barrel which are sequentially arranged in a sleeving manner from outside to inside, the upper ends of the coarse filtering barrel, the first-stage fine filtering barrel and the second-stage fine filtering barrel are all connected to the lower end of the lower top disc, and the butt joint ring is arranged on the upper surface of the lower top disc; the water sampling mechanism comprises an upper top disc and a water collecting bottle fixed at the lower end of the upper top disc, a water inlet is detachably formed in the lower end of the water collecting bottle, and a one-way valve is arranged at the water inlet; and the lower top disc is connected to the lower end of the upper top disc through a butt joint ring, and the water collecting bottle is located in the second-stage fine filtering barrel. The filtering process can be completed during water sampling, so that filtered water can be directly adopted during hydrological water quality detection, operation and maintenance are facilitated, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hydrology and water quality detection, and in particular relates to a filter device for hydrology and water quality detection. Background technique [0002] Hydrology and water quality detection is one of the most basic tasks of hydrology staff. Hydrology and water quality detection directly determines the impact of natural weather on the environment. Excellent hydrology and water quality detection data can avoid many natural disasters caused by water, and can play a preventive effect . Water for hydrological and water quality testing is usually drawn from rivers or underground. This type of water is usually accompanied by debris, and the debris in the water will not only affect the equipment, or even damage the equipment, but also have a great impact on the water quality to be tested. The influence makes the detected data have a great difference. At the same time, the water quality of water sources at ...

Water for hydrological and water quality testing is usually drawn from rivers or underground. This type of water is usually accompanied by debris, and the debris in the water will not only affect the equipment, or even damage the equipment, but also have a great impact on the water quality to be tested. impact, making the detected data have a large difference

At the same time, the water quality of water sources at different depths is also different, and the current hydrological water quality detection still needs to collect water first and then filter, so there are many operating steps, low work efficiency, and many equipment used, so it is very troublesome to maintain at the same time. Inconvenience caused by hydrology and water quality testing
