Abstract

The invention relates to the technical field of aquaculture, in particular to a deposition capturing device and an organism in situ culture device. The deposition capturing device comprises a main fixator, cross rods, supports, mounting racks and a capturing device; universal rotation rings are arranged at the two ends of the main fixator respectively, and the main fixator can rotate around its own axis; one ends of the cross rods are fixedly connected with the main fixator, the axes of the cross rods are perpendicular to the length direction of the main fixator, and the other ends of the cross rods are rotationally connected with the supports; the mounting racks are rotationally connected with the supports, the capturing device is fixedly connected with the mounting racks, and articulated shafts between the mounting racks and the supports are perpendicular to the axis of the capturing device; the distance from the top end of the capturing device to the plane where the mounting racks are located is smaller than that from the bottom end of the capturing device to the plane where the mounting racks are located. The organism in situ culture device comprises an air exchange mesh cover and the deposition capturing device. According to the deposition capturing device and the organism in situ culture device, long-time inclination of the capturing device can be effectively avoided, and accordingly, the sampling error is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a sediment capture device and a biological in-situ culture device. Background technique [0002] Water sediments record physical, chemical and biological information in the water environment. The sediment trap is a sampling device for collecting sediment in water bodies, and it is an indispensable sampling tool for modern water environment research. [0003] In the process of using the sediment capture device to collect water body sediment, hydrodynamic effects such as water flow and waves will cause the sedimentation tube to tilt. Due to the poor ability of the existing sediment capture device to resist the impact of water flow, the sedimentation tube cannot be tilted in time after the sedimentation capture device is tilted. The vertical state is restored, so that the total amount of sediment falling into the settling tube per unit time will decrease, resulting in a larger ...
