The invention discloses a buoyancy raft assisting in ship launching. The buoyancy raft comprises a ramp, a box body is arranged in water on the right side of the ramp; a sealing cavity is formed in the box body; an adjusting mechanism is arranged in the sealing cavity; the adjusting mechanism comprises a positioning block; the positioning block is fixedly connected with the inner wall of the rearside of the sealing cavity; a through hole is formed in the inner wall of the left side of the box body; a pressure film is fixedly arranged on the inner walls of the upper and lower sides of the through hole; a stressed plate is arranged on the right end surface of the pressure film in a contact manner; a first connecting rod is fixedly arranged on the right end surface of the stressed plate. According to the buoyancy raft, water pressure is utilized, water in a raft body is controlled to flow in and out; buoyancy borne by a raft can be adjusted according to the ship launching state; stress of a ship body of a launching ship is dynamically balanced, the gliding speed of the ship is controllable, the risks of rollover and ship collision are reduced, the possibility that the ship body is damaged is reduced, the ship body is attracted through electromagnets, the buoyancy raft is not prone to being separated from the ship, the multiple buoyancy rafts can be connected through iron chains to work, and meanwhile the buoyancy raft is suitable for transverse launching and longitudinal launching.
本发明公开了一种帮助船舶下水的浮力筏,包括斜坡,所述斜坡右侧水中设有箱体,所述箱体内设有密封腔,所述密封腔内设有调节机构,所述调节机构包括定位块,所述定位块与所述密封腔后侧内壁固定连接,所述箱体左侧内壁设有通孔,所述通孔上下两侧内壁固定设有压力膜,所述压力膜右端面接触设有受力板,所述受力板右端面固定设有第一连杆,本发明可利用水压,控制筏体内水的进出,可根据船舶下水状态调整筏所受浮力,动态平衡下水船舶的船身受力,使船舶下滑速度可控,降低侧翻和撞船风险,减少船身受损的可能,采用电磁铁吸附船身,使浮力筏与船舶不易脱离,且可采用铁链连接多个浮力筏进行工作,同时适用于横向下水与纵向下水。
