Water passing capping device for deep self filtering sealing water collector

Abstract

The invention discloses a water passing capping device for a deep self-filtering sealed water fetcher, and relates to the technical fields of environmental protection and water resources monitoring. The water sealing device is an indispensable and important functional part of the deep self-filtering sealed water dispenser, including the water sealing base, the water sealing ring, the water sealing cover positioning bracket, the water sealing cover, the water sealing Cover limit frame and water-through-wall water-passing sleeve; in the water-through-wall water-passing sleeve, from bottom to top, the water-passing cover base, water-passing sealing ring and upper hollow connection module are connected in sequence; The left and right ends on the cover base are respectively fixed with a water sealing cover positioning bracket and a water sealing cover limit frame; the left end point of the water sealing cover is connected with the water sealing cover positioning bracket. The invention can obtain a high-quality water sample whose impurity has been preliminarily filtered, accurately positioned, sealed and not mixed; the whole device has a simple structure, is convenient to carry, is durable, has remarkable economic benefits, and is easy to popularize.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and water resources monitoring, in particular to a water-passing capping device for a deep self-filtering sealed water fetcher. Background technique [0002] In order to ensure the needs of water body testing and monitoring in industries such as environmental protection, water conservancy, water resources, and urban domestic water, it is very important to quickly and accurately obtain water samples at specified locations and depths for accurate evaluation of water quality and pollution. In today's increasingly serious environment and water pollution, fast and accurate water sample filtration and selection technology is very necessary. However, at present, deep water sample collectors are scarce and immature, and the sampling location is not accurate. Due to the lack of sealing of the samples, the mixing of samples affects the quality of water samples, resulting in large deviation...
