Technical Field
The invention relates to the technical field of water vehicles, in particular to an improvement of a water airship.
Background
The inventor previously invented a water airship with a speed of 100 knots and a maximum of hundreds of knots, and the airship adopts front air injection and rear water injection steering. The defects are as follows: 1. the aft water jet steering device absorbs water from the stern, which causes the stern water pressure to drop and increases the resistance. 2. The backing effect is not good.
Disclosure of Invention
In order to overcome the above technical problems of the prior art, the present invention provides an improvement of a water airship. The specific technical scheme is as follows: the tail part of the jet water driving device with a steering and backing device is changed into a stern jet steering driving device.
In the technical scheme, the stern jet steering driving device comprises a stern control internal combustion engine power stern jet steering driving device, a bow control electric stern jet steering driving device and a bow control jet engine stern steering driving device.
Furthermore, the stern control internal combustion engine power stern jet steering driving device consists of an internal combustion engine, a wind wheel, a cylinder, a supporting rod, a base, an upper bearing, a lower bearing and a steering wheel. The internal combustion engine, the wind wheel, the cylinder, the supporting rod and the steering wheel are fixed together, and are connected with the upper bearing and the lower bearing which are fixed on the base and can freely rotate for 360 degrees, so that the steering and backing of the ship are realized. The cylinder and the wind wheel divide the space in the cylinder into a front (air suction) low-pressure area and a rear (air injection) high-pressure area; the power of the driving device is not only the counterforce of the wind wheel pushing air, but also the power assisting force generated by the front and back air pressure difference.
Furthermore, the jet steering driving device at the stern of the power ship with the bow-operated internal combustion engine consists of the internal combustion engine, a wind wheel, a cylinder, a supporting rod, a base, an upper bearing, a lower bearing, a switch control wire, a steering transmission wire and a control rod. The stern jet steering driving device is different from a stern steering internal combustion engine power stern jet steering driving device in that a steering wheel is not arranged, and the supporting rod and the steering rod are linked through a steering transmission line to realize 360-degree free rotation, so that steering and backing of the ship are realized. And the control of the bow is realized through a switch control line and a steering control line.
Furthermore, the bow-operated electric stern jet steering driving device consists of a wind wheel, a cylinder, a supporting rod, a base, an upper bearing, a lower bearing, a control rod, an electric motor, an electric switch controller, an electric rotating speed controller, a steering transmission line and a control rod. Unlike a bow-steered internal combustion engine powered stern jet steering drive, power is derived from an electric motor.
Furthermore, the bow is controlled jet engine stern and is turned to drive arrangement base, upper bearing, lower bearing, runing rest, jet engine on-off controller, jet engine speed controller, steering transmission line, control lever and constitute. The difference between the power of a bow-operated internal combustion engine and an electric stern jet steering driving device is that the power comes from a jet engine.
Compared with the prior art, the invention has the beneficial effects that:
(1) the jet steering driving device rotates freely for 360 degrees, thereby realizing steering and backing of the ship, and improving the steering angle range and backing effect.
(2) The adverse effect that the stern water pressure is reduced and the resistance is increased due to the fact that the stern water pressure is reduced when the rear water jet steering device sucks water from the stern is eliminated.
(3) The hydrodynamic device is completely abandoned, waves influencing the stable sailing of the ship are not actively generated, and the stability of the ship is higher.
