Problems solved by technology

[0006] For the ships involved in the above prior art, due to the many parts involved, the whole ship is large in size, heavy in weight, complex in structure, inconvenient for daily maintenance, and relatively high in cost. It is too fast, and if turning in situ is to be realized, the water jets need to be symmetrically distributed in structure. At the same time, the size of the retrograde rudder installed will be limited by the turning angle of the turning rudder

Embodiment 1

[0049] like figure 1 As shown, this embodiment discloses a reverse steering device for underwater propulsion and direction control, which includes a rudder 1 , a water jet 2 and a displacement device 3 .

[0050] Wherein, the number of the water jet propeller 2 is one. The rudders are arranged as a pair, and are relatively distributed on both sides of the vertical central axis of the water spout 6 . At the same time, each rudder 1 is connected to a shifting device 4, which is represented by a telescopic mechanism in this embodiment, and adopts hydraulic pressure, push-pull shaft or electric mode for telescopic operation, and is intended to drive the rudder 1 to deviate or Returns to the outside of the spout, but other mechanisms that serve the same purpose could be substituted.

[0051] Among them, the rudder is relatively distributed on the vertical central axis of the water nozzle, the purpose is to make the displacement device connected with it and give the push-pull forc...

Embodiment 2

[0060] The difference between this embodiment and Embodiment 1 is that the rudder 1 is arranged laterally on both sides of the vertical central axis of the water jet 6 of the water jet propeller 2 through the connecting strut 5 . Since the rudder 1 is arranged laterally, the hinge point 4 is located at the middle and lower part of the outer wall of the water jet propeller 2 .

[0061] The reason why the hinge point 4 is arranged on the middle and lower part of the outer wall of the water jet propeller 2 is that the rudder 1 is arranged on the longitudinal plane of the water jet 6 in a horizontal manner, because the rudder 1 is positioned on the side of the displacement device 3. During the push-pull process, since its own length is relatively small in the horizontal dimension relative to the longitudinal dimension, when it is necessary to change the force exerted by the sprayed water from the water nozzle 6 on the reverse rudder 1, the reverse rudder 1 is vertical to the water ...

Embodiment 3

[0067] The only difference between this embodiment and Embodiment 1 is that the rudder 1 on the left side is arranged laterally, so the corresponding hinge point 4 is arranged in the middle and lower part of the water jet propeller 2, as Figure 9 As shown, the reverse rudders 1 connected to the two water jets 2 are connected in different ways, and the principle of setting the hinge point 4 there is the same as that of Embodiment 2, and will not be repeated here. Of course, it is also possible that the rudder positioned on the left side is arranged longitudinally, and the rudder 1 positioned on the right side is arranged horizontally.

[0068] Depend on Figure 9It can be seen that it shows the state of turning counterclockwise in situ, the left rudder 1 does not deviate from the water nozzle 6, and the right rudder 1 completely deviates from the water nozzle 6, so the water flow on the left is moved forward by the rudder 1 The water flow on the right side is sprayed directly...

Abstract

The invention discloses a reverse steering device for propulsion and direction control in water, which includes a water jet propeller. There are at least two rudders for the water flow direction ejected by the water propeller; the shifting device is connected with the rudders and is used to drive the rudders to deviate from or return to the outside of the water nozzle of the water propeller. The water jet propeller is set as one; the rudder is set as a pair, and are relatively distributed on both sides of the vertical central axis of the water jet. Adopting the reverse steering device for underwater propulsion and direction control described in the present invention can still realize the functions of turning left, turning right, turning left in situ, turning in situ right and retreating while reducing the number of steering rudders, thereby The components are greatly reduced, while the volume is reduced, the weight is reduced, the speed is increased, the daily maintenance is convenient, and the related costs are relatively lower.

Description

technical field [0001] The invention belongs to the technical field of ship equipment, and in particular relates to a reverse steering device for underwater propulsion and direction control. Background technique [0002] At present, when a ship propelled by an existing water jet propeller needs to turn, the turning rudder deflects to the left or right, thereby realizing the left or right turn of the ship. In practice, the waterjet is generally installed below the waterline of the ship, and the water flow usually passes below two-thirds of the height of the waterjet when traveling, and the concave-convex gap formed between the waterjet and the turning rudder, Just around the height of the entire water jet propeller, a certain impact force is formed when the water flow passes through the turning rudder, resulting in a decrease in travel speed and an increase in energy consumption. Therefore, in order to reduce the impact force caused by the water flow to the turning rudder wh...
