Automatic fixed-depth water taking device and control method thereof

Abstract

The invention relates to an automatic fixed-depth water taking device and a control method thereof. The device comprises a mounted winch and a fixed-depth water sampler, wherein a storage battery, a winding drum shaft assembly, a steel wire rope, a coupler, a worm shaft assembly, a motor assembly, a mounted winch control module, a reciprocating lead screw rope arranging assembly, a pulley assemblyand a winch mounting bottom plate are arranged in the mounted winch. The lifting of the water sampler can be realized, and rope arranging and guiding structures are added, so that in a running process, the steel wire rope is stable in winding, small in jumping, difficult in bad phenomena of rope pressing, rope jumping, rope disordering, rope separation and the like, and reliable in structure. Thewater sampler comprises a water sampling bottle, an upper cover plate, a lower cover plate, an underwater control box, a waterproof connector, a pressure transmitter and an electromagnetic chuck. Thedevice can communicate with the winch and a remote controller to realize automatic and accurate fixed-depth water taking, and is convenient to operate. According to the device, existing two depth control methods are combined, and wireless signals are utilized, so that the control automation level is high, the structure is relatively economical, and the control function is stable.

Description

technical field [0001] The invention relates to the technical field of automatic water intake, in particular to an automatic depth-fixed water intake device and a control method thereof. Background technique [0002] According to statistics, my country's per capita water resources are only 2,200 cubic meters, which is only a quarter of the world level. It is one of the thirteen countries with the poorest per capita water resources in the world. In addition, as the discharge of industrial wastewater and domestic wastewater increases year by year, coupled with the lag in the construction of sewage treatment facilities, water quality problems are particularly prominent, so it is particularly important to strengthen water quality monitoring and control. [0003] At present, my country's water quality monitoring field mainly relies on manual monitoring, unmanned ship monitoring, and satellite remote sensing photography. Manual monitoring requires on-site sampling, which has a lon...

Problems solved by technology

Compared with the use of steel wire rope for lifting, this method has a smaller maximum water intake depth under the same structure, and is prone to bad situations caused by cable power failure and leakage, and the reliability of water intake is not enough.
