Embodiment Construction
[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:
[0038] The invention provides an automatic fixed-depth water intake device and a control method thereof, which can realize remote-controlled water intake by means of transportation such as drones. The invention has the advantages of simple operation, high automation level, high reliability of mechanical operation and stable control function, and is especially suitable for the collection of water samples in lakes, reservoirs and other water areas.
[0039] As an embodiment of the present invention, the present invention provides figure 1 As shown, an automatic fixed-depth water intake device is provided, including a mounted hoist 1 , a fixed-depth water extraction device 2 , a remote control 3 , a connecting rope group 4 , and an unmanned aerial vehicle 5 . like figure 2 , image 3 As shown, for the internal structure of the hoisti...

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...
