Problems solved by technology

However, when the existing unmanned ships adopt the pump pipe suction method, the number of sampling bottles in the existing design cannot be flexibly expanded, and the depth of each water sample collection cannot be controlled, which is difficult to meet the requirements of different applications
Moreover, in the application of water quality sample collection in large areas of water, if the number of sampling points is large and the distance is long, it will take a long time for sampling

Embodiment 1

[0047] The invention provides an unmanned ship device for automatic sampling of water quality, such as figure 1 , figure 2 , image 3 As shown, a preferred embodiment of the present invention is shown therein. Specifically, such as figure 1As shown, the unmanned ship device includes an unmanned ship main body 16, an energy source and control unit 17 disposed in the unmanned ship main body 16 cabin and an automatic water quality sampling unit, and the automatic water quality sampling unit includes a sampling bottle 6, The support body mechanism of the sampling bottle 6 is installed, the sampling pump 8 arranged on the outside of the unmanned ship main body 16, the sampling hose 7 connected to the sampling pump 8 and the swing arm water intake mechanism that controls the rotation of the sampling hose 7. The swing arm water intake mechanism includes a hollow tube 18 nested outside the end section of the sampling hose 7 and a first stepper motor 19 connected to the end of the ...

Embodiment 2

[0072] The present invention also provides a water quality automatic sampling method of an unmanned ship device, such as Figure 4 ~ Figure 10 As shown, a preferred embodiment of the present invention is shown therein. Specifically, the automatic sampling method of water quality comprises the following steps:

[0073] A. If Figure 4 As shown, the unmanned ship device is controlled by the program or remote command to sail to the sampling point, and the swing arm water intake mechanism is in a horizontal state under the sailing state.

[0074] B. If Figure 5 As shown, after the unmanned ship device reaches the sampling point, the first stepper motor drives the hollow tube to rotate, so that the lower end of the sampling hose and the filter head are immersed in the water, and the angle of the hollow tube is adjusted according to the requirements of the sample collection depth.

[0075] C. If Figure 6 As shown, the second stepper motor is controlled to drive the groove guid...

Abstract

The invention relates to an unmanned ship device and sampling method for automatic sampling of the water quality. The unmanned ship device comprises an unmanned ship body, an energy and control unit arranged in a bin of the unmanned ship body, and an automatic water quality sampling unit. The automatic water quality sampling unit comprises a sampling bottle, a supporting body mechanism for installation of the sampling bottle, a sampling pump arranged on the outer side of the unmanned ship body, a sample hose connected with the sampling pump, and an oscillating arm water-fetching mechanism forcontrolling the sampling hose to rotate. The oscillating arm water-fetching mechanism comprises a hollow pipe nested on the outer side of the tail section of the sampling hose, and a first stepping motor connected with the end, close to the sampling pump, of the hollow pipe. By means of the unmanned ship device and sampling method for automatic sampling of the water quality, water quality samplesof multiple sampling sites can be collected sequentially in a working cycle, the samples can be analyzed synchronously after being sent back, the sampling efficiency is further improved, and water quality samples of different areas or watersheds can be conveniently, quickly and automatically collected.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to an unmanned ship device and a sampling method for automatic sampling of water quality. Background technique [0002] In the field of water environment monitoring, to obtain true, accurate and complete water quality monitoring data, it is first necessary to obtain representative water quality samples. When collecting water samples for surface water bodies such as rivers, lakes, reservoirs, and coastal waters, it is necessary to collect not only water quality samples from the sampling points on the shore, but also water quality samples away from the sampling points on the shore. Usually, in the process of manual collection of water quality samples, sampling personnel need to take a boat to the sampling point to complete the collection. Manual operation is close to the water surface and is affected by climate, water flow and other conditions, so the risk factor is high; it n...
