Self-filtering sealing device of deep self-filtering sealing water collector

Abstract

The invention discloses a self-filtering sealing device of a deep self-filtering sealing water collector, and relates to the technical field of environmental protection and water resource monitoring. The self-filtering sealing device comprises a round hollow self-filtering gasket, a round self-filtering filter screen, a self-filtering seal cover base, a self-filtering sealing ring, a self-filtering seal cover positioning support, a self-filtering seal cover and a self-filtering seal cover limit frame, wherein the hollow self-filtering gasket is fixed on a bottom counterweight water inlet module through an annular thread, and the hollow self-filtering gasket, the round self-filtering filter screen, the self-filtering seal cover base and the self-filtering sealing ring are sequentially connected from bottom to top; the self-filtering seal cover positioning support and the self-filtering seal cover limit frame are fixed at the left end and the right end of the self-filtering seal cover base respectively; a left end point of the self-filtering seal cover is connected with the self-filtering seal cover positioning support. The round self-filtering filter screen is used for preliminarily and automatically filtering impurities, and automatic opening and closing of the self-filtering seal cover are realized according to buoyancy and resistance of water; the self-filtering sealing device is simple in structure, convenient to carry, durable in use and easy to popularize and has remarkable economic benefits.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and water resource monitoring, in particular to a self-filtering and sealing device of a deep self-filtering and sealing 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 d...
