Water sample collection device and method with cross-medium sailing function

Abstract

The invention provides a water sample collection device and method with a cross-medium sailing function. The device comprises a shell, the shell is provided with a control module and a depth sensor, and the shell comprises an upper cavity and a lower cavity; wherein the lower cavity is provided with a second valve, the control module is used for controlling the second valve to be opened and closed to collect a water sample, and the depth sensor is used for closing the second valve through the control module when the detected water depth position reaches a preset water depth position; the upper cavity is provided with a first valve and an elastic unit, the upper cavity further comprises a substance which can react with water and generate gas, the control module controls the first valve of the upper cavity to be opened, and after water flows into the upper cavity, the substance in the upper cavity generates gas after meeting the water; the gas can enable the volume of the elastic unit arranged on the upper cavity to be expanded so as to provide buoyancy for enabling the water sample collecting device to float and lift off. The water sample collection device is higher in water sampling speed.

Description

technical field [0001] The invention relates to the technical field of water sample collection robots, in particular to a water sample collection device and method with a cross-medium navigation function. Background technique [0002] With the rapid development of modern technology, we use smart devices more and more frequently in the fields of scientific research and daily life. In the marine field, the same is true for the collection of water samples. With the continuous development and maturity of the Internet of Things technology, the requirements for the intelligence and automation of water sample collection devices are also getting higher and higher. Because the automatic water collection device has the characteristics of relatively low cost, no risk of casualties, good maneuverability, and convenient use, the automatic water collection device is widely used in civilian applications. The main application markets include freshwater aquaculture, water quality testing, a...

Problems solved by technology

[0003] The current water sample collection devices and methods are time-consuming and laborious. The existing water sample collection devices and methods generally only collect underwater in a single medium field. Because the physical properties of air and water are very different, the density of water is It is more than 800 times that of air, and its viscosity coefficient is 59 times that of air. Therefore, it is necessary to provide a water sample collection device and method capable of navigating across media in the air and water, which is faster than the underwater collection system in a single field.
