[0026] Switching mechanism includes the center of collection net 6 fixedly installed with docking ring 7, and the opening end of sampling tube 5 is provided with spherical valve groove 8, and the inner side of spherical valve groove 8 is rotatably connected with spherical valve core 9, and the top end of spherical valve core 9 is fixedly installed with rotating shaft 10, and rotating shaft 10 is rotatably connected with the top end of sampling tube 5 through torsion spring, and the top end of sampling tube 5 is provided with opening and closing mechanism, which is used to drive rotating shaft 10 to rotate a certain angle when docking ring 7 is docked with the opening of sampling tube 5;

[0027] When working, unmanned plane body 1 moves to the designated sampling area, and connecting barrel 3 is slowly lowered to a certain depth, and the unmanned plane is started and moves towards the opening direction of connecting barrel 3, so that the water flow can pass through the inner side of connecting barrel 3, for example, as shown in Figure 1 When the water flow enters from the right end of connecting barrel 3, the water flow pushes collection net 6 and docking ring 7 to move left, so that the collection net 6 in the state of wrinkles is slowly stretched out until the left end of connecting ring is docked with the opening of left sampling tube 5, at this time, the opening end of left sampling tube 5 is in the inner side of connecting ring and closely fits, and collection net 6 is completely stretched out, at the same time, opening mechanism drives rotating shaft 10 in the inner side of left sampling tube 5 to rotate, and rotating shaft 10 drives spherical valve core 9 to rotate in spherical valve groove 8, so that the inner side of left sampling tube 5 is opened, at this time, the phytoplankton filtered by collection net 6 enters the inner side of left sampling tube 5 under the scouring of water flow, by setting opening mechanism, when docking ring 7 is docked with sampling tube 5, the inner side of sampling tube 5 is automatically opened, and when sampling tube 5 is idle, the opening of sampling tube 5 is closed, to prevent the sample collected inside from flowing out;

[0028] When the unmanned aerial vehicle drives the connecting cylinder 3 to collect in the water for a certain period of time, the unmanned aerial vehicle lifts the connecting cylinder 3 from the water, at this time, the collecting net 6 and the docking ring 7 are no longer subjected to the thrust of the water flow, and are separated from the opening of the left sampling pipe 5, and at the same time, the rotating shaft 10 is reset under the pushing of the torsion spring, the rotating shaft 10 drives the spherical valve core 9 to reset, so as to close the opening of the left sampling pipe 5 again, and prepare for the collection of another sampling pipe 5;

[0029] When one sampling pipe 5 completes the collection, the unmanned aerial vehicle only needs to move to another designated area, and then put the connecting cylinder 3 into the water again, and then the unmanned aerial vehicle moves towards the direction of the collected sampling pipe 5, and the above is the same, so as to realize the collection of the plankton in this area into another sampling pipe 5, the two sampling pipes 5 do not interfere with each other, realize the single flight of the unmanned aerial vehicle for twice sampling operation, greatly reduce the number of reciprocating sampling of the unmanned aerial vehicle, improve the efficiency of sampling of the plankton, save the labor, at the same time, reduce the burden of the unmanned aerial vehicle, avoid the situation that the unmanned aerial vehicle crashes due to insufficient power caused by reciprocating multiple times, and reduce the collection cost;

[0030] When the unmanned aerial vehicle moves towards the direction of the collected sampling pipe 5, the used collecting net 6 is turned inside out under the pushing of the water flow, so that the side filtered with plankton last time is on the outside, avoiding the mixing of the plankton collected last time into the sample collected this time, so that the sample result collected is more rigorous; when the water flow enters from the inside of the collecting net 6 this time, the plankton or sundries blocked on the surface of the collecting net 6 last time are washed away by the water flow, so as to realize the self-cleaning of the collecting net 6, further reduce the workload of the staff; solve the problem that the existing unmanned aerial vehicle for plankton sampling does not have the single-time multiple sampling function and the self-cleaning function of the collecting net 6.

[0032] As a further scheme of the present application, the bottom end of the docking ring 7 is fixedly installed with elastic belts 13 on the left and right sides, and the other ends of the two elastic belts 13 are fixedly connected with the lower sides of the two supporting frames 4 respectively; during operation, when the collection net 6 and the docking ring 7 are not in water, the two elastic belts 13 pull the docking ring 7 from the left and right sides, so that the docking ring 7 is kept at the center of the connecting cylinder 3; when the collection net 6 and the docking ring 7 are pushed by water flow, the elastic belt 13 in the direction of the water flow is stretched, and the elastic belt 13 in the moving direction of the docking ring 7 is contracted and naturally droops, thereby avoiding hindering the docking operation of the docking ring 7.

[0033] As a further scheme of the present application, the opening mechanism includes L-shaped rods 14 fixedly installed at the top ends of the rotating shafts 10, and the vertical ends of the L-shaped rods 14 are perpendicular to the sampling tubes 5; the top end of the docking ring 7 is fixedly installed with push plates 15 on the left and right sides, and the push plates 15 are horizontally arranged and correspond to the vertical ends of the L-shaped rods 14; during operation, when the docking ring 7 just contacts and docks with the sampling tube 5, the end of the push plate 15 contacts the vertical end of the L-shaped rod 14, and with the impact of water flow, the docking ring 7 is stably sleeved at the opening of the sampling tube 5, so that the push plate 15 pushes the rotating shaft 10 to rotate through the L-shaped rod 14, thereby providing power for the rotation of the spherical valve core 9.
