Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

The zooplankton sampling device shown in fig. 1 comprises a box body 1, a support 2, a movable door 4, a light source component, a filtering device, a sample cleaning device 3 and a sample collecting device. 1 both sides of box have the entry that supplies the zooplankton to get into sampling device, and the entry is fixed with filter equipment and is used for filtering aquatic impurity, and the light source subassembly is fixed in the entrance through the support for attract the zooplankton gathering, the inside belt cleaning device 3 that is fixed with of box, be used for wasing the zooplankton sample, and 3 both sides of belt cleaning device are fixed with floating gate 4, and floating gate 4 separates with the entrance when the sampling, after the collection is accomplished, be used for closed entrance. The bottom half is equipped with sample collection device and is used for collecting the zooplankton sample, and box outside bottom is fixed with support 2, can insert in the bed mud, is fixed in the water with whole sampling device.

The light source component consists of a 15w LED lamp 5 and a waterproof sealing cover 6, a battery is arranged at the bottom of the inner side of the waterproof sealing cover 6 to supply power for the lamp source, and zooplankton is gathered by utilizing the phototaxis characteristic of the zooplankton. The filtering device consists of a 100-mesh collection screen 7, and when planktons are collected, other impurities in water are prevented from entering the sampling device when the planktons smoothly enter the sampling device.
