Description
Claims (6)
- 海底又は海底近傍で引っ張られる物体(5)、例えば漁具の、物理的な着底又はそれに近い状態を検出する方法であって、
前記物体(5)に取り付けられている張力センサー(4)に連結されている鎖(6)又は類似物に質量体(7)を吊り下げ、
当初、前記鎖(6)又は類似物が垂直に近い状態であるように、前記鎖(6)又は類似物とは異なる方向から前記質量体(7)に連結するように、張力解放手段(8)を前記物体(5)に取付けることからなり、
前記質量体(7)が海底と物理的に接触し、前記鎖(6)又は類似物が弛むと、前記張力センサー(4)が、弛んだことを検出し、かつ前記物体(5)及び/又は直接上方の船の装置に信号を送信し、
海底に沿って前記質量体(7)が引っ張られることによって生じる摩擦力(F2)のほとんどが、前記張力解放手段(8)によって吸収されることを特徴とする方法。 - 海底又は海底近傍で引っ張られる物体(5)、例えば漁具の、物理的な着底又はそれに近い状態を検出する装置であって、
質量体(7)であって、張力センサー(4)が、当該質量体(7)の着底による鎖(6)又は類似物の弛みによって起動し、前記物体(5)及び/又は直接上方の船の装置に信号を送信するように、当該張力センサー(4)から、当該鎖(6)又は類似物に吊り下げられている質量体(7)と、
前記鎖(6)又は類似物とは異なる方向から前記質量体(7)に連結されているとともに前記物体(5)に取付けられている張力解放手段(8)であって、海底に沿って前記質量体(7)が引っ張られることによって生じる摩擦力(F2)を吸収するように適合されている張力解放手段(8)とによって特徴付けられている装置。 - また前記鎖(6)又は類似物が、前記張力解放手段(8)を構成している請求項2に記載の装置。
- 前記質量体(7)の吊り下げ箇所が、前記鎖(6)又は類似物に沿って変化するように適合されている請求項2又は3に記載の装置。
- 前記鎖(6)又は類似物が、弱い継ぎ目要素を介して、前記張力センサー(4)に連結されている請求項2〜4のいずれか1項に記載の装置。
- 前記張力センサー(4)が、信号を音響によって伝達する手段に連結されている請求項2〜5のいずれか1項に記載の装置。
