Problems solved by technology
[0004] However, the structural form of this kind of water jet propeller adopts the way of closing the water gate, which will cause the water flow to turn sharply, and the length of the reversing pipe is usually long, which will cause a large energy loss and have a great impact on the speed of the amphibious vehicle. And the steering and reversing of the amphibious vehicle are not flexible enough, and it is not easy to use

The invention provides a nozzle device of a water-jet propeller, and the nozzle device comprises a connecting spray pipe which is provided with a connecting end; a steering spray pipe which comprises a first steering pipe section and a second steering pipe section connected with the first steering pipe section, wherein an included angle not smaller than 90 degrees is formed between the central axis of the first steering pipe section and the central axis of the second steering pipe section, the first steering pipe section is connected to the connecting end in a rotating mode, and the first steering pipe section is communicated with the connecting end in a sealed mode; and a driving assembly which is located on the connecting spray pipe, and is configured to drive the first steering pipe section to rotate. According to the invention, an amphibious vehicle can be rapidly controlled to steer and reverse, a large amount of energy cannot be lost in the steering and reverse navigation process, and the navigational speed of the amphibious vehicle is guaranteed.
Description
technical field [0001] The present disclosure relates to the technical field of water jet propulsion devices, in particular to a nozzle device of a water jet propulsion device. Background technique [0002] An amphibious vehicle is a vehicle that can navigate on water by itself without auxiliary equipment such as pontoons and ferries. Amphibious vehicles usually use water jet propulsion as the power device for water navigation. Since amphibious vehicles need to have certain cross-country obstacle-crossing capabilities, the water jet propulsion and other components are arranged inside the cabin of the amphibious vehicle. Amphibious vehicles equipped with water jet propulsion usually adopt water gates, reversing pipes and side rudders to realize steering and reversing. [0003] In the related art, the water jet propeller of the amphibious vehicle includes: the tail nozzle of the water jet propeller, the reversing pipe and the water gate, the tail nozzle runs through the shell...
