一种用于拖网渔具释放水母的装置制造方法及图纸

一种用于拖网渔具释放水母的装置，涉及拖网附属装置，需要提供一种使水母从网具中释放出去的装置，防止网目堵塞、网具爆破，降低目标渔获物释放率。本实用新型专利技术包括在上网片开有释放口的一节网身，其特征是该节网身的前段内侧有一片斜置的引导网，引导网的前边与该节网身的上网片前边缝合，引导网两边分别与该节网身的左右网片缝合，引导网的下边与该节网身的下网片之间是渔获物的导入口；该节网身的后段内侧有一片斜置的分离栅，分离栅外框成矩形，分离栅中有横档，分离栅中部至上部均布纵向栅，分离栅下部是目标渔获物通过口，分离栅上框配扎浮子并扎在该节网身的上网片释放口的后沿，分离栅下框扎在渔获物导入口后方该节网身的下网片中部。（*该技术在2016年保护过期，可自由使用*）

Device for releasing jellyfish in trawl fishing gear

A device for releasing trawlnets jellyfish, relates to trawl attachment, need to provide a device that makes jellyfish released from nets, mesh nets to prevent clogging, blasting, reduce catches release rate. The utility model comprises a piece in the Internet has a net release of the export section, which is characterized in that the inner side of the net body has a inclined guide guide network, network and the network of the front section of front guide net net slice suture, both sides around mesh were connected with the net section the next screen guide network with the net section below is the import of the catch; there is a diagonal split gate after the inner side of the net body, separated into rectangular gate frame, a gate rung separation, the separation of the central gate to the upper longitudinal uniform grid, separation the lower gate is target catches by the mouth, isolated gate frame with tie and tied at the festival float net online release port along the bar in the middle, under the net catches the rear entrance guide section net frame isolation gate.
