Problems solved by technology

[0002] The steering of the existing water-jet ships is generally realized by the rudder, and the reverse is realized by decelerating the power, then reversing, and then accelerating. Since this process takes a long time, it is impossible to make the ship in case of an emergency. Stop the ship immediately in case of a situation, which is prone to shipping accidents

Embodiment Construction

[0010] As can be seen from FIGS. 1 to 3 , the present invention includes a propeller conduit 1 , a cylinder 2 for reverse flow guidance, two cooperating guide covers 3 , a hydraulic drive rod 4 , and a connecting rod 5 . The front end of the propeller duct 1 is connected to the ship, and the rear section radially penetrates the cylinder 2 to the cylinder surface of the cylinder. The upper and lower surfaces of the two wind deflectors 3 are fixed on the upper and lower surfaces of the cylinder 2 by the pivot pin 6 . Located on the same vertical line drawn by the central line of the propeller guide tube, the two shrouds are rotated around the two shaft pins 6 of the same axis. The space between the two shrouds 3 and the cylindrical surface of the cylinder 2 is a reverse flow guide channel 8, which is used for spraying the water in reverse direction when the two shrouds are closed. The two wind deflectors 3 are respectively equipped with a connecting rod 5, and the connecting ro...

Abstract

A mechanism of the water-jet ship for the running backward and steering during the running backward is composed of a cylindrical body for reversely guiding water flow, two guide tubes of propulsion and with a front end communicated to ship and a back segment passing through said cylindrical body, and two opposite flow guiding bossings outside the cylindrical body and controlled by hydraulic drive rods for changing the direction of jet nozzle.

Description

technical field [0001] The invention relates to a reverse-steering device of a water jet ship. Background technique [0002] The steering of the existing water-jet ships is generally realized by the rudder, and the reverse is realized by decelerating the power, then reversing, and then accelerating. Since this process takes a long time, it is impossible to make the ship in case of an emergency. In case of emergency, stop the ship immediately, which is prone to shipping accidents. Contents of the invention [0003] The invention aims to provide a reverse-steering device for a water-jet ship, which can quickly stop the water-jet ship, retreat, and turn during the retreat, to ensure the safety of the ship and to facilitate the operation of the ship. [0004] The water jet ship reverse-steering device provided by the present invention includes a propeller guide, a cylinder for reverse flow guide, and two cooperating guide covers; the front end of the propeller guide is connec...
