Bottom sinking type automatic surface water sampling system

Abstract

The invention discloses a bottom sinking type automatic surface water collecting system. The system comprises a water tank, a water collection pump, a pipeline, a floating rod, a filter, a buoy, a heavy block, fixing steel ropes, fixing piles and a control unit, the two water collection pumps are arranged in the closed water tank; the water collecting pump is connected with a water inlet pipelineand a water outlet pipeline; the floating rod is flexibly connected with the water tank water inlet; a sand outlet is formed in the bottom of the water tank; the water tank is prevented from being washed away; heavy blocks are connected to two ends of the water tank; meanwhile, the front end of the water tank is connected to the fixed pile; after the control unit sends a water sampling command, the water sampling pump is started, surface water to be detected enters the water tank from the floating rod water inlet hole and is conveyed to the automatic water quality monitoring station pretreatment unit through a pipeline, the water sampling system is provided with a cleaning pipeline and a backwashing pipeline at the same time, backwashing can be conducted on the water sampling system, and the whole water sampling system is subjected to instruction sending through the control unit. The water sampling system is low in construction cost, low in construction difficulty, high in operability,low in operation and maintenance cost and suitable for rivers, lakes and reservoirs with relatively shallow water levels and slow water flow.

Description

technical field [0001] The application of the present invention relates to a bottom-sinking automatic water collection system for surface water, which belongs to the field of automatic monitoring of water quality. Background technique [0002] The automatic water quality monitoring system is composed of a water sampling system, a water distribution and pretreatment system, an analysis system and a control system. The automatic water sampling system is the basis of the automatic monitoring system. If the water sampling system is not designed properly or the water sample is in the pipeline Physical and chemical reactions will produce errors in test results, which in turn will affect water pollution prevention and government decision-making. At present, the common water collection methods of the surface water automatic monitoring water collection system include trestle water collection, buoy / boat / buoy water collection, cantilever water collection, pontoon water collection and c...

Problems solved by technology

[0005] In order to overcome the current situation in the prior art when the water level of rivers or lakes is relatively shallow, the water flow is relatively slow, and at the same time, the water level changes significantly during the wet season or dry season, and the water sampling system cannot collect representative water samples. The present invention provides a A water collection system that moves with the water level to ensure that representative water samples can be collected even during low water levels or wet seasons
