Abstract
Description
Technical Field
[0001] The utility model relates to water environment monitoring, in particular to an unmanned monitoring ship for river channels. Background Art
[0002] In recent years, in the work of investigating river pollution outlets, unmanned ships not only act as supervisors more and more often, but also shoulder the role of sampling. In real-time sampling and monitoring during some emergency monitoring of sudden environmental pollution incidents and a large number of point detections, however, during the process of river sampling by unmanned ships, the sampler lacks a preliminary filtering device, which will not only cause deviation in the results of subsequent real-time sampling and monitoring, but also increase the frequent occurrence of failures of monitoring equipment. In daily monitoring, due to the lack of preliminary filtering treatment, the time of the whole process of water sample monitoring will also be increased, consuming more manpower and material resources.
[0003] On the other hand, in order to ensure the cleanliness of the collected samples, it is usually necessary to clean not only the sampling pipes to avoid other impurities being mixed in the collected samples and affecting the final detection results of the samples. The existing unmanned sampling ships usually travel along a predetermined route, drive to a designated water area for sampling work, and it is impossible to avoid surrounding waterweeds, gravel, and other solid substances from entering the pump during the sampling process, resulting in insufficient cleanliness of the collected samples. Summary of the Invention
[0004] The utility model aims to solve the above problems of the prior art and provides a sampling preliminary filtering device for an unmanned monitoring ship for river channels. The utility model can remove impurities and particulate matters therein for subsequent analysis and treatment.
[0005] The utility model is realized as follows: A sampling preliminary filtering device for an unmanned monitoring ship for river channels includes a sampling pipe fixed in the middle on a fixing frame of the hull. The lower end of the sampling pipe located in the water is provided with a preliminary filter and is fixed on a fixing bayonet of a locator; a motor reel is arranged at the bottom of the unmanned ship, and the locator is suspended by winding a wire on the reel; a movable support plate is arranged inside the ship body, a sample bottle is arranged under the movable support plate, a water pump and a sample bottle locator are arranged above the movable support plate, and the other end of the sampling pipe passes through the hull and is connected to the water pump inlet.
[0006] In the sampling preliminary filtering device for an unmanned monitoring ship for river channels, the water pump is a self-priming pump.
[0007] In the sampling preliminary filtering device for an unmanned monitoring ship for river channels, the preliminary filtering device is a porous cage-shaped structure, the material is stainless steel, and it also has a screw thread connected to the sampling pipe, and the water intake joint is a one-way filtering water intake joint.
[0008] A simple and efficient sampling and preliminary filtering device for an unmanned river sampling boat provided by the utility model can improve the quality of water samples collected by the unmanned boat during the sampling process by adding a simple and easily obtainable preliminary filtering device and driving the swing arm to swing by driving the rotating shaft so that the water intake joint is located at different depths below the water surface for unmanned boat sampling of the river. At the same time, the items used are simple and easily obtainable, and the waste will not cause secondary pollution. BRIEF DESCRIPTION OF THE DRAWINGS
