Long-shot riverway water quality sampling device

Abstract

The invention provides a long-shot riverway water quality sampling device, and relates to the field of water quality sampling. The long-shot riverway water quality sampling device comprises a buoy, clamping noses are fixedly installed on the left side and the right side of the buoy, the two clamping noses are hinged through a connecting frame, the connecting frame is located above the buoy, a balancing weight is fixedly installed at the bottom end of the buoy, the balancing weight comprises a fixed balancing weight and an adjusting balancing weight, and the fixed balancing weight is fixedly installed at the bottom end of the buoy. The long-shot riverway water quality sampling device is connected with an existing throwing type fishing rod for throwing, the buoy and a central shaft are arranged, the buoy can sink into water under the action of the balancing weight after long-shot, and the device moves downwards under the action of gravity, so that a hinge four-rod mechanism can be extruded and deformed through a square shaft to jack up a sealing gasket, finally, the effect of collecting water in a riverway can be achieved, and the problem that in the prior art, sampling is inconvenient is solved.

Description

technical field [0001] The invention relates to the technical field of water quality sampling, in particular to a remote-casting type river channel water quality sampling device. Background technique [0002] With the rapid development of society and economy, the problem of environmental pollution has become increasingly prominent, especially the problem of water environment pollution is showing the trend of regional expansion, pollution diversification, and seriousness. Facing the global environmental problems and the increasingly severe water crisis, the protection of water resources has become an urgent problem that human beings face. In order to strengthen the monitoring of water environment quality, grasp the current situation of water quality in a timely manner, determine the temporal and spatial distribution of pollutants in the water body, and then trace the source of pollutants, the way of pollution and the impact on human health, it is necessary to conduct a large ...

AI Technical Summary

Problems solved by technology

[0003] When the existing river channel is sampled, because the water surface of the river channel is relatively wide, in order to sample the water in the center of the river channel, the existing technology is to row a boat to the center of the water surface and then lower the sampling device from the boat, so that it needs to be sampled every time. Requires boat assistance, so you need to carry the boat every time you take a sample, which leads to the inconvenience of sampling
