Embodiment 1

[0038] Such as Figure 1~13 As shown, a new shallow sea plankton layered collection device includes a rectangular grid 1 with upper and lower openings, the four corners of the grid 1 are connected with suspension rings 2, the outer surface of the grid 1 is fixed with a water collector 3, and the grid 1 is connected with a The collection net 4 is connected with the bottom pipe 10 of the biological net at the end of the collection net 4, and the bottom pipe 10 of the biological net is arranged inside the bottom basket 5, and the bottom basket 5 is fixedly connected with the suspension ring 2 by a rope. The inner wall of the grid 1 is provided with a horizontal slideway 9, and the slideway 9 is embedded with a closing rod 6 and an opening rod 8, and the number of the slideway 9 is four. The side of the closing rod 6 facing the opening rod 8 is provided with a groove, the bottom of the groove is connected with a zipper 7, the height of the opening rod 8 is 0.8 of the height of the...

Embodiment 2

[0041] Such as Figure 1~13 As shown, a new shallow sea plankton layered collection device includes a rectangular grid 1 with upper and lower openings, four corners of the grid 1 are connected with suspension rings 2, a water collector 3 is fixed on the outer side of the grid 1, and the inner surface of the grid 1 is connected There is a collection net 4, and the bottom end of the collection net 4 is connected with a bottom pipe 10 of a biological net. Ring 2 is used for rope fixing this device, is convenient to control this device to enter water, and the four corners of grid 1 are all provided with ring 2, can improve the stability of this device when lowering and hoisting; While collecting plankton samples, water samples can also be collected. Two collections are completed in one operation, which not only improves the efficiency of collection operations, but also reduces resource consumption and reduces the impact on the ecological environment; the collection net 4 collects ...

Embodiment 3

[0056] Such as Figure 1~13 Shown, a kind of novel shallow sea plankton layered collection device, its collection method is: adopt rope to fix suspension ring 2, suspension ring 2 is fixed on the lifting device of offshore operation, and the zipper belt 42 of collection net 4 net mouth places One side is connected to the closed rod 6, the other side is connected to the open rod 8, the end of the collection net 4 is connected to the fixed net ring 101, and the collection net 4 equal to the number of water layers to be collected is connected in the grid 1, and the bottom basket 5. An equal number of biological net bottom tubes 10 are also fixed inside. When the initial state is set, the closing rod 6 and the opening rod 8 are all on one side of the grid 1. All the network ports of the collection net 4 are closed. Valve 103 and lower valve 106 are closed, and the loam cake 19 and lower cover 15 of water collector are also closed. When the launch command is issued, the collection...

Abstract

The invention discloses a novel neritic plankton hierarchic collection device and application thereof and belongs to the technical field of plankton collection. The device comprises a rectangular gridwith upper and lower openings, a hanging ring is connected at each of four corners of the grid, a water collector is fixed on the outer side face of the grid, a collection net is connected in the grid, the tail end of the collection net is connected with a biological net bottom pipe which is arranged inside a bottom basket, and the bottom basket is fixedly connected with the hanging rings throughropes. The application refers to using the device for neritic plankton hierarchic collection. The device is portable in size and simple to operate, hierarchic collection at different water depths canbe realized, simultaneous analysis on vertical movement of plankton can be helped greatly, and collection of the plankton and collection of water bodies for water quality parameter analysis can be realized at the same time, so that the number of collection times is reduced effectively, resource consumption is lowered, and water body analysis effectiveness and device using efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of plankton collection, in particular to a novel shallow sea plankton layered collection device and its application. Background technique [0002] Plankton generally refers to drifting organisms that live in water and lack the ability to move effectively, including phytoplankton and zooplankton. Some plankton have the ability to swim, but their swimming speed is often slower than the ocean current in which they are located, so they cannot swim flexibly in the water effectively. Plankton (plankton), among the organisms in oceans, lakes and rivers, has no ability to move at all, or is very weak, so it cannot move against the current, but lives on the surface of the water. These organisms are collectively called plankton biology. [0003] Plankton sampling is one of the important contents of marine surveys. Since different plankton have great differences in their vertical movement characteristics, layered sam...
