Problems solved by technology

[0005] The rotation of the steering handle is realized by the cooperation of two hydraulic cylinders. If the telescopic lengths of the piston rods of the two hydraulic cylinders do not match, it will cause problems in the rotation of the steering handle, and the water jet propeller cannot turn normally.
For ships sailing at high speed, water jets cannot turn normally, which may cause the risk of the ship hitting bridges and other ships
Therefore, the steering device in the related art is unreliable

Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0027] An embodiment of the present disclosure provides a steering device for a water jet propeller. figure 1 It is a schematic structural diagram of a steering device of a water jet propulsion provided by an embodiment of the present disclosure. see figure 1 , the steering device includes a steering nozzle 10 , a rack 20 , a rack 30 and a hydraulic cylinder 40 .

[0028] The diverting nozzle 10 has a nozzle water inlet 101 (such as figure 2 shown) and the nozzle outlet 102 communicated with the nozzle inlet 101. The toothed disc 20 is fixedly connected with the steering nozzle 10 , and the axis of the toothed disc 20 is perpendicular to and intersects the axis of the nozzle water outlet 102 . The rack gear 30 meshes with the ...

Abstract

The disclosure provides a steering device for a water jet propulsion device, which belongs to the field of ship propulsion devices. The steering device includes a steering nozzle, a gear plate, a rack and a hydraulic cylinder; the steering nozzle has a nozzle water inlet for being installed on the water outlet of the water jet propeller and a nozzle communicated with the nozzle water inlet Water outlet; the toothed disc is fixedly connected with the steering nozzle, the axis of the toothed disc is perpendicular to and intersects the axis of the nozzle outlet; the rack is meshed with the toothed disc; the hydraulic cylinder includes a piston A rod and a cylinder for fixing on the water jet propeller, the first end of the piston rod is slidably arranged in the cylinder, the second end of the piston rod is connected with the rack The first end is coaxially connected. The entire process of the present disclosure is driven by one hydraulic oil cylinder without involving the cooperation of two hydraulic oil cylinders, has high reliability and low implementation cost, and is especially suitable for ships sailing at high speed.

Description

technical field [0001] The present disclosure relates to the field of ship propulsion devices, in particular to a steering device of a water jet propulsion device. Background technique [0002] The water jet propulsion is a kind of propulsion tool of the ship, which propels the ship together with the ship's power plant. The jet part of the propulsion mechanism of the water jet propeller is immersed in water, and the reaction force generated by the jet water is used to drive the ship forward, and the steering device changes the jet direction of the water flow to realize the steering of the ship. [0003] In the related art, the steering device includes a steering nozzle, a steering cover, a steering handle and two hydraulic cylinders. The steering cover is fixed outside the water outlet of the water jet propeller, and the steering nozzle is rotatably installed on the water outlet of the water jet propeller and protrudes from the steering cover. The middle part of the steeri...
