【摘要】：自返式微型地熱探針水下運動特性以及其貫入深度關系到其能否正常入泥工作,針對自返式微型地熱探針的結構,對其進行簡化,建立物理模型。并針對海洋流場及海洋底質,抽取關鍵參數(shù),建立探針投放過程中的流場模型和底質模型。將所建立模型導入數(shù)據(jù)分析軟件,先分析探針在投放過程中豎直方向和水平方向的相關運動特性,然后擬合為探針下行過程中下行深度和橫向漂移的軌跡圖,可見其水平方向最大位移約為106 m。在理論上論證了探針在下行過程中的姿態(tài)穩(wěn)定性。通過計算論證了自返式微型探針在依靠自身重力的情況下,自動貫入海底沉積物進行熱流測量工作方式的可行性。并在最后通過海上試驗,對分析結果進行了實踐驗證。
[Abstract]:The underwater motion characteristics and penetration depth of self-return micro-geothermal probe are related to its normal mud entry. Aiming at the structure of self-return micro-geothermal probe, the physical model is established, and the ocean current field and ocean bottom are analyzed. The key parameters are extracted, and the flow field model and the bottom mass model are established. The model is imported into the data analysis software to analyze the vertical and horizontal movement characteristics of the probe. Then fitting the trajectory diagram of the depth and lateral drift of the probe in the downlink process. It can be seen that the maximum displacement in horizontal direction is about 106 m.The stability of the probe's attitude in the downlink process is theoretically demonstrated. The self-return microprobe is proved to depend on its own gravity by calculation. It is feasible to measure the heat flux of the sediment through the sea bed automatically. Finally, the results of the analysis are verified by practice through the sea test.
