Method for efficiently detecting benthonic animals

Abstract

The invention relates to the technical field of benthonic animal detection, in particular to an efficient benthonic animal detection method, which comprises the following steps that a rope is elongated through a winding mechanism, and two buckets pull the rope downwards under the action of gravity and sink into a bottom mud bed; the two buckets get close to each other through an adjusting mechanism, and after the side faces of the two buckets make contact, the bottom mud and the benthonic animals are excavated into the buckets together; an output shaft of a second servo motor rotates to drive a gear to work synchronously, the gear drives a rack to move synchronously, the rack drives a sieve plate to move in two sliding rails, the sieve plate moves to the bottom of a cylinder and is used for receiving soil poured out of two buckets, bottom mud and benthonic animals on the sieve plate are washed through a spraying mechanism, and the bottom mud and benthonic animals on the sieve plate are cleaned through a cleaning mechanism, a water solution mixed with the soil is discharged from the sieve holes, and the benthonic animals are separated; and the benthonic animals are taken out and detected. According to the invention, digging and conveying of soil are facilitated, and then the convenience and stability of the soil in the digging and conveying process are improved.

Description

technical field [0001] The invention relates to the field of detection of benthic animals, in particular to a method for detecting benthic animals with high efficiency. Background technique [0002] When sampling benthic animals, it is necessary to dig out the bottom soil of the water body through a dredging device, then transport the excavated soil to the shore for cleaning, and then count the number of benthic animals in the soil after cleaning. In the process of dredging, the excavation and screening operations are usually carried out manually. Due to the heavy gravity of the excavated soil, it is more laborious in the process of taking out, and in the process of screening benthic animals, it is also more laborious, resulting in work. Personnel consume a large amount of labor, thereby reducing work efficiency. Contents of the invention [0003] The object of the present invention is to propose a method for detecting benthos with high efficiency in order to solve the sh...
