The invention relates to a folding and unfolding system which comprises a ship body. The retracting and releasing device is mounted on the ship body and is used for mounting an oil return machine; the retracting and releasing device can drive the oil return machine to move outwards so as to stretch out of the side face of the ship body or move inwards so as to retract into the ship body from the side face. The retracting and releasing device comprises at least two stages of retracting and releasing mechanisms which are connected in sequence, the uppermost stage of retracting and releasing mechanism is connected with the ship body, and the oil return machine is installed on the lowermost stage of retracting and releasing mechanism; in every two adjacent stages of retracting and releasing mechanisms, the upper stage of retracting and releasing mechanism drives the oil return machine to move inwards or outwards relative to the ship body through the lower stage of retracting and releasing mechanism, and the lower stage of retracting and releasing mechanism drives the oil return machine to move inwards or outwards relative to the upper stage of retracting and releasing mechanism; the second position where every two adjacent stages of retracting and releasing mechanisms jointly drive the oil return machine to move inwards is closer to the inner side than the first position where the previous stage of retracting and releasing mechanism independently drives the oil return machine to move inwards.

    本申请涉及一种收放系统,包括:船体;收放装置,收放装置安装于船体上,并用于安装回油机;收放装置能够带动回油机向外运动以从船体的侧面伸出,或向内运动以从侧面缩回至船体内;收放装置包括至少两级依次相连的收放机构,最上一级收放机构与船体连接,回油机安装于最下一级收放机构上;每相邻两级收放机构中,上一级收放机构通过下一级收放机构带动回油机相对于船体向内或向外运动,下一级收放机构带动回油机相对于上一级收放机构向内或向外运动;每相邻两级收放机构共同带动回油机向内运动的第二位置,较其所包含的上一级收放机构单独带动回油机向内运动的第一位置靠内。
