Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figures 1 to 6, a kind of seawater automatic sampling device based on unmanned plane, including multi-rotor unmanned aerial vehicle, automatic liter
Falling unit and sampler, the sampler are arranged on the lower section of multi-rotor unmanned aerial vehicle by apparatus for automatically lifting；
The apparatus for automatically lifting includes threephase asynchronous machine 1, motor driver 2 and electric machine controller 3, and described three is different
Step motor 1 is connected with motor driver 2, electric machine controller 3, and motor is rotated under the control of driver, controller controlled motor
Start to rotate, stop operating and rotate forward reversion etc.；
The electric machine controller 3 is arranged on fixed disk 15, and threephase asynchronous machine 1, motor driver 2 are fixed on flat board 10
On, there is aperture on flat board 10, flat board 10 is installed to below fixed disk 15 by band or screw, the fixed disk 15 is arranged on
Below multi-rotor unmanned aerial vehicle；
The sampler includes multiple reels 5, suspension rod 7, setline 12 and sample bucket 6, the wheel face of the reel 5
11 be annular shape, and central area 13 is hollow state, and reel 5 is enclosed on the motor shaft 4 of threephase asynchronous machine 1 by central area
On, the benefit so designed is can to need practical particular number of reel according to actual conditions, reduces load-carrying, more just
Just；There are multiple reels 5 on motor shaft 4, it is necessary to which explanation, the internal diameter of reel 5 is bigger than motor shaft 4.
The setline 12 is wound on reel 5, and unwrapping wire and function of receiving line, setline are realized under the rotation driving of motor
Specific length is according to oneself needing to formulate, and setline can bear 1KG or so weight；
The setline 12 is hitched by fixed pulley end inside the handle 16 above the sample bucket, the sample bucket 6
Side is provided with cavity 9, and the outer wall of cavity 9 is big density material wall 8, when being sampled below sample bucket 6, and bucket is because big density material
Heavier mass at wall and centre-of gravity shift, such bucket are inclined when overboard, and water can be hence into bucket.When in sample bucket
When water reach a certain height, because there is cavity 9 at big density material wall 8, center of gravity starts to be displaced to a barrel center, so works as completion
When sampling rises, would not come down in torrents sample because of centre-of gravity shift.
There is the controllable projection 14 of two rows on the motor shaft 4, controllable projection 14 is connected with electric machine controller 3, passes through electricity
Machine controller 3 controls projection, can realize and allow any sample bucket to be sampled, and is also achieved that many sub-samplings.It is described controllable
The effect of projection 14 is, the evagination or embedded under the manipulation of electric machine controller.There is spring inside described controllable raised 14.When
When reel 5 needs to be enclosed on or remove on motor shaft 4, it can control projection 14 and embed., every time can be with when needing seawater to sample
One or more sample bucket is put down, the mode of realization is exactly that can control raised 14 evagination to be tightly fastened coiling by both sides
Wheel 5, the sample bucket for the reel of so ining succession will be laid down in the presence of motor rotation, and controllable projection 14 is without outer
Convex but embedded corresponding reel 5 can not follow rotation because not being connected closely with motor shaft 4.
It should be pointed out that for those skilled in the art, before the utility model principle is not departed from
Put, some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection domain of the present utility model.This reality
Applying each part being not known in example can use prior art to be realized.
