Water quality sampling unmanned catamaran and sampling method thereof

Abstract

The invention discloses a water quality sampling unmanned catamaran and a sampling method thereof, and belongs to the technical field of environment monitoring. The water quality sampling unmanned catamaran comprises two catamaran bodies arranged in parallel, wherein the two catamaran bodies are in rigid connection through a fixed trapezoidal frame above the catamaran bodies; an upper platform anda lower platform are arranged on the trapezoidal frame; a cylindrical tube penetrating through the upper platform and the lower platform is arranged in the middle of the trapezoidal frame in a penetrating way; a windlass corresponding to the cylindrical tube is arranged on the upper platform; a bearing support frame matched with the windlass is also arranged on the upper platform; a water collecting pipe is wound on the windlass; one end, passing through the cylindrical tube, of the water collecting pipe is connected with a water sample collector; the other end of the water collecting pipe isconnected with a peristaltic pump fixed on the upper platform; and a water sample distributor is arranged on the lower platform, and is connected with the peristaltic pump. Through the arrangement ofa water sample collection device on the unmanned catamaran in parallel arrangement, the stability of the water sample collection device in the unmanned catamaran moving process is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to an unmanned catamaran for water quality sampling and a sampling method thereof. 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. However, manual operation has the following disadvantages: (1) It is close to the water surface and is affected by climate, w...

Problems solved by technology

However, manual operation has the following disadvantages: (1) It is close to the water surface and is affected by climate, water flow and other conditions, so the risk factor is large; (2) It needs to consume man-hours, and there are costs such as ship use and fuel power, which consume a lot of manpower and material resources; ( 3) The operation is complicated, the single sampling time is long, and the time between different sampling points is long, which affects the timeliness of water sample analysis; (4) The difference in the quality of sample collection due to the difference in the habits of personnel during operation is not conducive to water quality analysis and comparison; (5) When the sampling point is in a special terrain such as narrow or insufficient water depth, it is difficult for ordinary ships and personnel to reach and complete the sampling

However, when the existing unmanned boats collect water samples, they will not be stable enough when encountering wind and waves, and the depth of water sample collection cannot be controlled. It is difficult to collect water samples at different depths in different water areas, and cannot accurately record water Relevant indicators when the sample was collected
