Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] Such as figure 1 As shown, a subsidence type artificial discharge device includes: a counterweight 1, a shellfish holding tank 2, a floating ball 3 and several trigger mechanisms 4.

[0022] The shellfish holding tank is surrounded by a base plate 2.1, a top plate, and four side plates 2.2, front, rear, left, and right sides, wherein the lower edges of the front, rear, left, and right side plates are hingedly connected with the base plate through hinge shafts 2.0 respectively, and the front, rear, left, right, and left sides are all able to Rotate about the corresponding hinge axis. The hinge axis is set horizontally. The top plate includes a connection frame 2.4 located between the front, rear, left, and right side plates and a cover plate 2.5 located above the connection frame and connected to the connection frame. The connection box...

Abstract

The invention discloses a settling artificial releasing device. Through the provided settling artificial releasing device, on the one hand, the problem that since shellfish seeds can be carried away by ocean currents easily before attachment of the shellfish seeds is achieved, the shellfish seeds are distributed to a seabed area unsuitable for the attachment and growth of the shellfish seeds, andthe survival rate of the shellfish seeds is reduced can be effectively solved; on the other hand, the problem that a net-shaped tank cover can not be opened or be opened prematurely due to poor sealing can be effectively solved. The settling artificial releasing device includes a floating ball, a balancing weight, a shellfish temporary-keeping tank and a plurality of trigger mechanisms, wherein the shellfish temporary-keeping tank is defined by a bottom plate, a top plate and four surrounding side plates, and the lower edges of the four surrounding side plates are connected with the bottom plate through articulated shafts in a hinged mode respectively; the top plate comprises connecting frames, which are arranged between every two of the four surrounding side plates, and a cover plate which is arranged above the connecting frames and connected with the connecting frames, the balancing weight is connected with the bottom plate through a lower connecting rope, and the floating ball is connected with the cover plate through an upper connecting rope; a one-to-one correspondence exists between the trigger mechanisms and the four surrounding side plates.

Description

technical field [0001] The invention relates to a discharge device, in particular to a subsidence type artificial discharge device. 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 one to two weeks for shellfish seedlings to attach to the seabed, this makes it easy for shellfish seedlings to be taken away by ocean currents and randomly distributed to various places on the seabed. However, many seabeds are not suitable for the attachment and growth of shellfish seedlings (such as bottom mud sea areas), which make...
