Intermittent type shellfish releasing boat

Abstract

The invention discloses an intermittent type shellfish releasing boat, and aims to provide the intermittent type shellfish releasing boat with the advantages of low labor intensity, good releasing uniformity and capability of improving the survival rate of shellfish. The boat comprises a counterweight, a stand column arranged on a boat body, a lifting platform frame capable of ascending and descending along the stand column, an intermittent type self-releasing device arranged on the lifting platform frame and located under the lifting platform frame, and vertical partition sleeves arranged on the boat body and penetrating a deck and a bottom plate, wherein the vertical partition sleeves are located below the under the lifting platform frame, and the intermittent type self-releasing device which can pass through the vertical partition sleeves is located below the boat body; the intermittent type self-releasing device comprises a fixed partition drum with an horizontally-arranged axis, a movable releasing drum rotatably arranged inside the fixed partition drum through a rotating-shaft rod, and a first drive impeller arranged on the rotating-shaft rod; the rotating-shaft rod and the axis of the fixed partition drum coincide; the lower part of the outside surface of the fixed partition drum is provided with a fixed releasing outlet; and the outside surface of the movable releasing drum is provided with a movable releasing outlet.

Description

technical field [0001] The invention relates to a releasing device, in particular to an intermittent shellfish releasing ship. Background technique [0002] Marine proliferation and release of shellfish refers to the fishery method in which shellfish are released into natural ocean waters where shellfish resources have declined after artificial breeding and seedlings, so that the natural population of shellfish can be restored, and then fishery methods are carried out reasonably. [0003] At present, the general method of releasing shellfish is to pack the seedlings, transport them to the sea area for release by a transport ship, and then manually release the seedlings in a certain sea area. The current artificial shellfish release method often produces the problem of too concentrated release, so that the seedlings cannot be evenly spread to the seabed, which affects the survival rate and growth of the seedlings, and affects the release effect. On the other hand, the artifi...

Problems solved by technology

The current artificial shellfish release method often produces the problem of too concentrated release, so that the seedlings cannot be evenly spread to the seabed, which affects the survival rate and growth of the seedlings, and affects the release effect.

On the other hand, the artificial shellfish release method is not only labor-intensive and cannot be released in large quantities; moreover, personnel may fall into the water due to the influence of wind and waves during the release operation, which has certain potential safety hazards
