The invention discloses a buoyancy dynamic balance laying and recycling method for a submarine pipeline surveying and mapping tool. The buoyancy dynamic balance laying and recycling method comprises a laying method and a recycling method. The laying method comprises the steps that the surveying and mapping tool is integrally and slowly hoisted into the sea, and buoyancy in the laying process is adjusted through the water inflow of the buoyancy chamber and the balancing weight; the scanning cabin is closed behind the seat post; seawater in the scanning cabin is discharged to the buoyancy chamber, after the buoyancy chamber is filled with the seawater, the remaining seawater is discharged to the outside, the balancing weight is completely put down, and the pneumatic diaphragm pump is normally opened; the recovery method comprises the following steps: pumping air into the buoyancy chamber, so that seawater in the buoyancy chamber is downwards poured into the scanning cavity; inflating and pressurizing the scanning cabin, opening the scanning cabin, and filling the scanning cabin with seawater; the balancing weight steel wire rope is loosened, and the hoisting steel wire rope is tensioned; the crane slowly lifts, the buoyancy chamber is inflated and drained to increase buoyancy, meanwhile, the hydraulic winch continues to loosen the steel wire rope of the balancing weight, the surveying and mapping tool and the balancing weight are integrally lifted out of water, and tool recycling is completed. Buoyancy dynamic balance laying and recovery of the surveying and mapping tool can be achieved.

    本发明公开了一种用于海底管道测绘工装的浮力动态平衡布放与回收方法,包括布放方法和回收方法;布放方法:将测绘工装整体缓慢吊放入海,通过浮舱进水量和配重块调节布放过程中的浮力;坐管后将扫描舱关闭;将扫描舱内的海水排至浮舱,待浮舱充满后,将剩余海水排到外界,将配重块完全下放,常开气动隔膜泵;回收方法:向浮舱内打气,使浮舱内的海水下灌到扫描腔;向扫描舱内充气加压,开启扫描舱,海水充满扫描舱;使配重块钢丝绳松弛,吊装钢缆张紧;吊机缓慢起吊,向浮舱中打气排水增大浮力,同时液压绞车继续放松配重块钢丝绳,将测绘工装及配重块整体起吊出水,完成工装回收。本发明能够实现测绘工装的浮力动态平衡布放和回收。
