Problems solved by technology

[0006] The box type is generally used in static sampling. In dynamic sampling, the position of the box body cannot be artificially fixed due to the resistance of the water, and it is easy to rub against the hull and cause damage due to impact. The method of trawling is easy to entangle with underwater objects, such as breeding area or some floating objects, it is also impossible to take stable samples for a long time
At present, the continuous sampling method of the scientific research ship during the voyage is generally to install one or more sampling tubes on the side of the ship, extend the sampling tubes into the seawater 20-30cm below the water surface, and use the pumping equipment to pass the sampling tubes to the position. The surface seawater is collected on the ship, but there are some problems with this sampling method. First, the scientific research ship has a certain speed when sailing, and the sampling tube will be subjected to continuous resistance of the seawater when collecting the surface seawater, which will cause the sampling tube to generate upward buoyancy. Not only will it affect the position of the sampling tube underwater, but it is also difficult to fix the sampling tube on the ship's side; second, even if the traditional sampling tube is firmly fixed on the ship's side, the long-term continuous navigation of the scientific research ship will cause continuous resistance in the seawater. The sampling tube will bend the sampling tube and cause damage; thirdly, how to stably fix the sampling tube on the side of the ship is still a problem that needs to be solved

Abstract

The invention discloses a scientific expedition vessel with continuous sampling device for surface water during sailing process, which comprises a vessel body. The vessel body is characterized in thatthe ship rail of the ship body is provided with a device for continuously sampling the surface water below the water surface. The device includes a cross beam capable of lifting along the ship rail.The cross beam is fixedly provided with a sampling pipe for sucking and sampling the surface water and a hydraulic cylinder for driving the cross beam to ascend and descend to extend the sampling pipeto the surface water position; a buffer mechanism is arranged on the cross beam to prevent damage to the sampling tube caused by the continuous resistance of the sea water during the sailing of the ship. The vessel not only effectively ensures that the surface water can be accurately taken out, but also continuous acquisition can be realized during the sailing process of the vessel. The buffer mechanism not only effectively avoids the damage of the sampling pipe on the axial direction and the radial direction due to continuous flow resistance effect, but also can realize the mitigation of theresistance, and the service life of the sampling device is prolonged.

Description

technical field [0001] The invention relates to the technical field of scientific research ships, in particular to a scientific research ship with a device for continuously sampling surface water during sailing. Background technique [0002] Microplastics, which are plastic particles with a diameter of less than 5 mm, are a major carrier of pollution. Microplastics include polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyurethane, polyamide, polyethylene terephthalate, etc. Microplastics are small in size, which means higher specific surface area (specific surface area refers to the surface area per unit mass of porous solid matter), and the larger the specific surface area, the stronger the ability to adsorb pollutants. First of all, there are already a lot of persistent organic pollutants such as PCBs and bisphenol A in the environment (these organic pollutants are often hydrophobic, that is to say, they are not easy to dissolve in water, so they often ca...
