The invention relates to the related technical field of seabed exploration equipment, in particular to a seabed grab bucket capable of preventing volatilization and loss of samples. The seabed grab bucket capable of preventing volatilization and loss of samples comprises a grab bucket base arranged above the seabed, a power transmission mechanism used for transmitting power to the grab bucket base is arranged on the grab bucket base, and the grab bucket base can be remotely controlled by a worker on a ship to conduct grabbing operation through the power transmission mechanism. A rotating core is fixed to the end wall of the side, close to the seabed, of the grab bucket base, and an opening and closing mechanism used for grabbing seabed samples is arranged on the rotating core. According to the seabed grab bucket, a large amount of loss of a sample after grabbing of the grab bucket can be prevented, and a large amount of volatilization of hydrates in the sample due to water pressure and water temperature can be prevented.
本发明涉及海底勘探设备相关技术领域,具体为一种能够预防样品挥发与散失的海底抓斗。一种能够预防样品挥发与散失的海底抓斗,包括设于海底上方的抓斗基座,所述抓斗基座上设有用于向所述抓斗基座输送电力的输电机构,所述输电机构可供工人在船只上远程遥控所述抓斗基座进行抓取作业,所述抓斗基座靠近海底一侧端壁上固定有转芯,所述转芯上设有用于抓取海底样品的张合机构。本发明不仅能够防止在抓斗抓取完成后样品的大量散失,也能够防止样品中的水合物由于水压和水温而大量挥发。
