The invention belongs to an instant high-efficiency active reversing device for a high-performance ship, which takes a water-jet propeller as a propelling device, and is characterized in that under the condition that an original reversing device of the water-jet propeller is not changed, a movable folded plate mounted on the high-performance ship is arranged in front of a water suction pipe of the water-jet propeller, and the bending of water flow upstream of the water-jet propeller is realized; when parking or reversing is needed, a hydraulic oil cylinder is driven to enable a flow guide reversing plate to move to the position below the ship body and the upstream of a water inlet flow channel of the water-jet propeller along a supporting and positioning sliding rail, and the device is an active reversing device. Water flow bending is achieved on the upstream of the water-jet propeller, once an impeller rotates, thrust formed in the water inlet pipe at the earliest is backward, the reversing effect is instantly formed, due to the fact that the original forward thrust in the water inlet pipe is turned to be backward through water flow bending, efficiency is obviously improved, instant reversing of the high-performance ship in the static state can be achieved, and the forward rushing fault during reversing in the static state is avoided.
本发明属于一种以喷水推进器为推进装置的高性能船舶的瞬时高效率主动倒车装置,在不改变喷水推进器原有倒车装置的情况下,通过在喷水推进器的吸水管前方设置有安装在高性能船舶上可移动折板,实现在喷水推进器上游的水流折弯作用,在需要停车或者倒车的时候,驱动液压油缸,使导流换向板沿支撑定位滑轨运动到船体下、喷水推进器进水流道上游,这是一种主动倒车装置。通过在喷水推进器上游实现水流折弯,这样一旦叶轮转动,在进水管内最早形成的推力就是后向的,这样就瞬时形成倒车作用,由于水流的折弯使进水管内原来的前向推力转向为后向,效率明显提高,可以实现高性能船舶在静止状态下的瞬时倒车,避免静止状态下倒车时出现前冲故障。
