| 摘要: |
| 潜标测量系统中的仪器设备, 因受单拖网、双拖网、流网等各种海洋工程探测装备干扰而大多被损坏或严重丢失; 国内外因此相继出现的防拖潜标测量装置, 因系留绳占了防拖架内的大部分空间,导致防拖架过高, 起不到防拖的理想效果。针对以上问题, 于2012 年, 完成最初样本的设计, 后经不断改进和完善, 设计了掩体式防拖潜标探测装置, 该设计将连体潜标与掩体合成为掩体式防拖平台,掩体高度仅为40 cm、弧形坡度不超过40°, 构成了体积最小的掩体式防拖单元, 具有很强的防拖功能。该装置适用于浅海海区水深230 m 且底质条件不是软泥并且较平坦的海域, 可有效预防和解决测量仪器受渔网、各类船只航行作业干扰、破坏等难题。该装置已在渤海进行了3 个多月、在南海进行了近6 个月的试验性测量, 其结果良好。 |

| Design and investigation of anti-dragging blockhouse submerged buoy |
|
|
| Abstract: |
| The instruments of the submerged buoys measurement system are often damaged seriously or lost because of disturbances coming from the otter trawler, pair trawler or drift fishing. So the anti-dragging submerged buoy measurement sets have been invented one after another both in home and abroad. But the captive rope has taken up most of the inside space of the anti-dragging framework. This directly results in that the framework is too high and the anti-dragging effects are not ideal. Based on the above questions, the new blockhouse type anti-dragging submerged buoy has been invented. The new invention combines the double submerged buoy with the blockhouse and forms an anti-dragging blockhouse platform. The height of the blockhouse is only 40 cm and the slope of arc is less than 40°. The anti-dragging blockhouse unit has the minimum volume and a strong anti-dragging capability. The device is suitable for the shallow sea with a water depth of 230 m, whose bottom sediment is not ooze. The device has been used in the Bohai Sea for more than 3 months and in the South China Sea for almost 6 months. The results show that the new innovation can effectively solve arduous problems such as the measurement instruments are disturbed by various sorts vessels and hydrographic environment measurements are destroyed, etc.. |
