Self-triggering type stocking device based on gravity changes

Abstract

The invention discloses a self-triggering type stocking device based on gravity changes, and aims at providing the self-triggering type stocking device. With the device, the problem that the shellfishfry is easily brought away by an ocean current before attachment and is distributed to a seabed area which is not suitable for attachment growth of the shellfish fries, so that the survival rate of the shellfish fries is reduced can be effectively avoided, and the problem that a net-shaped box cover cannot be opened or is opened in advance caused by poor sealing performance can be effectively avoided. The device comprises a counterweight base, wherein a vertical guide column is arranged in the middle of the upper surface of the counterweight base; the device comprises a shellfish temporary rearing box, wherein the shellfish temporary rearing box is composed of a bottom plate, a top plate, a front side plate, a rear side plate, a left side plate and a right side plate, the lower edges of the front, rear, left and right side plates are respectively hinged to the bottom plate through hinge shafts, a lower guide sleeve matched with the vertical guide column is arranged in the middle of the bottom plate, and an upper guide sleeve matched with the vertical guide column is arranged in the middle of the top plate; and the device comprises a plurality of settlement separating type connecting mechanisms, wherein the settlement separating type connecting mechanisms are in one-to-one correspondence with the front, rear, left and right side plates.

Description

technical field [0001] The invention relates to a shellfish releasing device, in particular to a self-triggering stocking device based on gravity change. Background technique [0002] Artificial shellfish ecological restoration means that shellfish are released into natural marine waters where shellfish resources have declined after artificial breeding and breeding, so that the natural population of shellfish can be restored. At present, the general method of artificial shellfish ecological restoration is to pack the seedlings, transport them to the release sea area by a transport ship, and then manually sow the seedlings in a certain sea area. Since it takes about a week for shellfish seedlings to attach to the seabed, it is easy to be taken away by ocean currents during the period from shellfish seedlings to the seabed to attachment, and they are randomly distributed to various parts of the seabed. The bottom of the sea is not suitable for the attachment and growth of she...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method that can not only effectively prevent shellfish seedlings from being easily taken away by ocean currents before attachment, and be distributed to seabed areas that are not suitable for shellfish seedling growth, but also reduce the survival rate of shellfish seedlings. The problem; and the structure is simple, which can effectively avoid the problem that the mesh box cover cannot be opened or opened in advance due to poor sealing.
