Abstract
The invention belongs to an instantaneous high-efficiency active backing device of a high-performance ship by taking a water jet propeller as a propelling device, which realizes the water flow bending effect at the upstream of the water jet propeller by arranging a movable folded plate arranged on the high-performance ship in front of a water suction pipe of the water jet propeller under the condition of not changing the original backing device of the water jet propeller, and drives a hydraulic cylinder to enable a flow guide reversing plate to move to the lower part of a ship body and the upstream of a water inlet flow channel of the water jet propeller along a support positioning slide rail when the ship needs to be stopped or backed, thereby being the active backing device. Through realizing that rivers bend in water jet propulsion ware upper reaches, in case the impeller rotates like this, the thrust that forms earliest in the inlet tube is just backward, just so the effect of backing a car of instantaneous formation, because bending of rivers makes the original forward thrust turn to for backward in the inlet tube, efficiency obviously improves, can realize that high performance boats and ships are instantaneously backed a car under quiescent condition, appears the forward fault when avoiding backing a car under the quiescent condition.

It is known that when operating on water, ships encounter a wide variety of special situations, in particular high performance ships, where maneuverability at high speeds and braking/reversing characteristics are particularly important.
However, the traditional reversing method of the water jet propeller is to install a reversing water bucket for bending jet flow at the downstream of a nozzle of a stern, and the reversing water bucket is a passive reversing device. The realization of the reversing performance of the water jet propeller is required to depend on the flow rate of the water jet propeller, and the flow rate of the water jet propeller is realized by the incoming flow in the suction pipe from the front lower part, and the incoming flow direction forms forward acting force on a high-performance ship. Therefore, the efficiency of the classic reverse bucket reverse mode is very low, the effect is poor, and the brake distance of the high-performance ship is very long. Especially when the high-performance ship needs to be backed in a static state, the forward acting force formed in the water suction pipe under the rotation action of the impeller is earlier than the backing backward thrust generated by the backing water bucket, so that the high-performance ship can be instantaneously rushed forward, and accidents such as ship/shore collision, ship/ship collision and the like are easy to happen.
