Problems solved by technology
The steering and reversing mechanism of the water jet propulsion device does not have this function, so the course stability of the water jet propulsion ship is generally poor
[0007] The second is that the suction effect of the water jet propulsion device at the inlet accelerates the water flow, and the pressure near the bottom and stern of the ship drops, causing the ship to tilt and increase the resistance

Embodiment Construction
[0033] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.
[0034] The invention provides a gear-driven water jet propulsion device manipulation mechanism, such as Figure 8-Figure 10 Shown, it is made up of inner rudder stock 3-2, outer rudder stock 3-1, shell 3-3, upper jaw 3-5, lower jaw 3-7, bevel gear set 3-4 and cylindrical gear set 3-6. The inner rudder stock 3-2 and the outer rudder stock 3-1 are sleeve shaft structures, which can be rotated independently or together. The outer rudder stock 3-1 is rigidly connected with the outer rudder stock 3-3, and the outer rudder stock 3-3 rotates together with the outer rudder stock 3-1; the inner rudder stock 3-2 passes through a cone between the outer rudder stock 3-3 and the bevel gear set 3-4 The gears are connected, and the bevel gear rotates together with the inner rudder stock 3-2. The casing 3-3 is a door-shaped casing, and the inle...

The invention discloses a gear-driven water jet propulsion device control mechanism which is characterized by comprising an inner rudderstock, an outer rudderstock, a shell, an upper jaw and a lower jaw, the outer rudderstock is sleeved on the outer side of the inner rudderstock, the outer rudderstock is rigidly connected with the shell, the inner rudderstock penetrates through the shell and is connected with a transmission gear set, the upper jaw is connected with the transmission gear set through a first transmission shaft, and the lower jaw is connected with the transmission gear set through a second transmission shaft. The lower jaw is connected with the transmission gear set through a second transmission shaft; when the inner rudderstock rotates, the transmission gear set drives the upper jaw and the lower jaw to rotate together. The reversing mechanism is simple and reliable in reversing action, and the precision requirement for installation and positioning is lowered; the device is suitable for a single device; during reversing, a reversing water flow deflection channel formed by the mechanism is stretched, so that the loss during water flow deflection is reduced; the water jet propulsion device has certain capabilities of improving the ship course stability and adjusting the ship attitude, and overcomes the defects of the water jet propulsion device.
Description
technical field [0001] The invention relates to a water-jet propulsion device control mechanism, in particular to a gear-driven water-jet propulsion device control mechanism, which belongs to the field of ship special propulsion devices. Background technique [0002] Waterjet propulsion devices usually rely on the steering and reversing mechanism to realize the steering and reversing functions of the ship. The principle is to change the jetting direction of the water flow through the action of the mechanism, thereby changing the direction of the force generated by the propeller to change the motion of the ship. At present, the main steering and reversing mechanisms include box-type steering and reversing mechanisms suitable for built-in water jet propulsion devices (such as figure 1 shown) and combined rudders suitable for externally suspended water-jet propulsion devices (such as figure 2 , image 3 shown). [0003] Such as figure 1 As shown, the box-type steering and ...
