The invention discloses an aufwuch anti-escape sampling device which comprises a cube frame, a hanging plate disposed in the cubic frame, a buoy connected to the hanging plate, a first storage box, asecond storage box, a first wrapping object and a second wrapping object, wherein the first storage box and the second storage box are disposed on the buoy, the first wrapping object is disposed in the first wrapping object and used for sleeving the outer side of the cube frame, and the second wrapping object is disposed in the second storage box and used for wrapping the first wrapping object. Electromagnets are disposed in the first storage box and the second storage box. The first wrapping object and the second wrapping object each include a spring and a wrapping cloth disposed on the outerside of the spring. The lower open end of each wrapping cloth is provided with a rubber ring enlarged by a water-soluble substance. The buoy, the hanging plate and the cubic frame are connected through a rope. The aufwuch anti-escape sampling device has the advantages that the aufwuch anti-escape sampling device is simple and convenient to operate; the cube frame is arranged outside the hanging plate, and the cubic frame is wrapped with the first wrapping object and the second wrapping object, so that the aufwuch can be prevented from escaping.
Description
technical field [0001] The invention relates to the technical field of marine organism collection equipment, in particular to an escape-preventing sampling device and a sampling method that are simple in operation and can prevent attached organisms from escaping. Background technique [0002] The investigation of attached organisms is an important survey item of marine pastures and artificial reefs. After artificial fish reefs are placed, the type and quantity of attached organisms on them are important indicators for evaluating their effects. The traditional method is to hang the board with ropes and hang it at sea. After sampling by diving or pulling the rope up, wrap the board with gauze and immerse in the fixative. However, there will be a problem of some attached organisms escaping when taking the hanging board. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides an anti-escape sampling device and ...
