When the water body organism capturing device is in a state ready for capturing, the capturing folding structure 301 and the negative pressure structure 302 are both in an overall contraction state, when the capturing operation is started, the capturing folding structure 301 and the negative pressure structure 302 are driven by the driving device 1, and the negative pressure generated by the negative pressure structure 302 is utilized to suck the prey into the capturing folding structure 301.
When the number of the driving devices 1 is 2, opposite sides of the negative pressure structure 302 are connected to the movable frame 203 and the fixed frame 202, respectively. The opposite sides of the capture fold 301 are connected to the web 107. Correspondingly, the number of the closing doors 114 is two, and when the moving member 102 moves in a retracting manner, 2 closing doors 114 are driven by the third link 113 to rotate along the middle portion of each closing door 114 to close the closing doors 114. At this time, the 2 closed doors 114 and the capturing folding structure 301 form a closed accommodating space to prevent the captured aquatic organisms from being lost.
The working process and the principle of the water body biological capture device are as follows:
as shown in fig. 1-2, assuming that the water body organism capturing device starts to work from the ready-to-capture state, the capturing folding structure 301 and the negative pressure structure 302 are in the contracted state, when the soft organism in the water approaches the inlet of the capturing folding structure 301, the fixed member 101 drives the moving member 102 to move, and cooperates with the spring 1014 in the compressed state to push the first slider 105 to contract upwards, and the first slider 105 further drives the connecting plate 107 connected with the capturing folding structure 301 to move upwards, so that the capturing folding structure 301 expands to generate the negative pressure, and the biological sample is sucked in. Meanwhile, the first slider 105 drives the third link 113 to move, and the negative pressure structure 302 moves along with the movable frame under the driving of the third link 113 to generate negative pressure, thereby enhancing the negative pressure suction effect of the capturing folding structure 301. Meanwhile, the moving member retracts to sequentially drive the first slider 105, the third slider 111, the third link 113 and the second link 112, the second link 112 drives the closing door 114 to rotate along the middle of the closing door 114 to close the closing door 114, and the closing door 114 gradually changes from the open state to the closed state to prevent the biological sample from escaping (shown in fig. 2).
Similarly, when the moving element moves in a relaxation mode and drives the moving element to drive the capturing device to reset, the fixed element 101 drives the moving element to move in a downward relaxation mode, the compression spring 1014 stores energy, meanwhile, the capturing folding structure 301 and the negative pressure structure 302 contract under the driving of the moving element, and the closing door 114 rotates under the driving of the moving element and gradually changes from a closed state to an open state, so that preparation is made for the next capturing (shown in fig. 1).
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes in the features and embodiments, or equivalent substitutions may be made therein by those skilled in the art without departing from the spirit and scope of the invention.
