Problems solved by technology

For the steering device of this type of structure, when reversing, the required connecting parts (seat lugs) are stressed, and the stress distribution is uneven. When steering, the turning water flow is guided to generate a reflection flow that reduces thrust, resulting in thrust loss.
In addition, the steering device with the above structure has a complex structure, and the rudder shell with a square mouth structure is inflexible in manipulation and unstable in force. Moreover, the product consumes a lot of money, and installation and maintenance are troublesome, which is not conducive to the popularization and application of the product.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] According to shown in Fig. 1, the turning device of waterjet propulsion ship of the present invention comprises propulsion pump spout 1 and rudder shell 2, and the leading edge of propulsion pump spout 1 is connected with propulsion pump, and the leading edge of rudder shell 2 is connected with propulsion pump spout 1. The rear edge is connected, and the two are matched and installed. The front edge of the rudder shell 2 is in contact with the rear edge of the nozzle 1 of the propulsion pump through the connector 3. In the present invention, the front edge of the rudder casing 2 and the rear edge of the nozzle 1 of the propulsion pump are matched in an arc surface , the inner surface of the nozzle 1 of the propulsion pump is a smooth arc surface structure, specifically: the inner surface of the front edge of the rudder shell 2 fits on the outer surface of the rea...

Abstract

The present invention discloses one kind of retch equipment for water-jetting propelled ship. The retch equipment includes one boost pump jet with front edge connected to the boost pump and one rudder shell fitting to the boost pump jet through one connecting piece. The front edge of the rudder shell is fitted to the back edge of the boost pump jet. The present invention can guide the jetted water flow from the boost pump jet, and the water flow is turned inside the rudder shell to reach the ship retching aim. The present invention has the advantages of homogeneous distribution of stress, great thrust efficiency, minimized loss, etc.

Description

technical field [0001] The invention relates to the field of ship turning devices, in particular to a water jet propelling ship turning device. Background technique [0002] In the water jet propulsion technology of the ship, the turning device is the key equipment for supporting the water jet propulsion of the ship. Maneuvering purpose for diversion. In the existing steering device of this type, the rudder body is mostly a square-shaped structure along the rudder shell at the back of the propulsion pump nozzle, and the rudder shell with a square mouth structure behind the nozzle is in the steering (especially at the maximum rudder angle of about 30° on the left and right). °) In order to accommodate the water flow injected from the propulsion pump, the front edge of the rudder shell is trumpet-shaped, and the entire rudder shell is plate-shaped. For the steering device of this type of structure, when reversing, the required connecting parts (seat lugs) are stressed, and t...
