Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] see figure 1 , the present invention is provided with ship's ballast water classification filtering device A, flowmeter B and suction filtration pump C, according to the direction of ship's ballast water flow, flow meter B is arranged on ship's ballast water classification filtration device A and suction filtration pump C Between, ship ballast water sampling device A and flow meter B and between flow meter B and suction filter pump C are connected to each other through water pipes.

[0020] see figure 2 , The ship's ballast water classification filter device is mainly composed of five parts such as the top cover 1, the second-stage filter collar (the upper collar 2 and the lower collar 3), the base 4 and the outer collar 5. There is an interface on the top cover 1, which can be connected with a water pipe so as to extend into the ballast water of the ship; T...

Abstract

This invention disclosed a classification sampling device for water plankton. It consists of filtration device, flowmeter and a pump. The flowmeter was in between the filtration device and the pump and they were connected by water pipe. There are coping, base and outer collar fixed on the filtration device. Sampling could be done efficiently and precisely by this invention.

Description

technical field [0001] The invention relates to a sampling device for ship's ballast water, in particular to a device which can realize rapid and accurate graded sampling of plankton in ship's ballast water by combining with a flow meter and a suction filter pump. Background technique [0002] The invasion of marine organisms caused by ballast water has become one of the biggest environmental challenges faced by the global shipping industry in this century. Ship transportation brings about tens of billions of tons of ballast water to all parts of the world every year, and there are at least 7,000 to 10,000 kinds of marine microorganisms and Animals and plants flow around the world with ballast water (Hu Chengbing. Preventing "riding" alien biological invaders in ballast water. Transportation and Environmental Protection, 1999, 20(4): 35-39.). So far, it has been confirmed that about 500 species of alien biological invasions are transmitted by ship ballast water, causing a se...
