Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 to 3, a component type water jet propulsion device with a changeable array comprises a device housing 1, an independent propulsion unit 7, a first water jet propulsion unit 6, two combined propulsion units 8, two lifting mechanisms and four waterproof steering engines 2, wherein the device housing 1 is rectangular, the two lifting mechanisms are symmetrically arranged on a pair of side walls of the device housing 1, the independent propulsion unit 7 and the first water jet propulsion unit 6 are arranged on the bottom surface of the device housing 1 side by side, the two combined propulsion units 8 are symmetrically arranged on two sides of the independent propulsion unit 7 and the first water jet propulsion unit 6, the upper parts of the combined propulsion units 8 extend into the device housing 1, the four waterproof steering engines 2 are all arranged in the device housing 1, and the independent propulsion unit 7, the first water jet propulsion unit 6 and the two combined propulsion units 8 are respectively connected with one waterproof steering engine 2.
The combined propeller set 8 comprises a propeller set fixing frame and two second water-spraying propellers, wherein the two second water-spraying propellers are arranged in parallel up and down and fixed on the propeller set fixing frame, one second water-spraying propeller is positioned in the device shell 1, the other second water-spraying propeller is positioned below the device shell 1, and the propeller set fixing frame is connected with the lifting mechanism through the waterproof steering engine 2.
The independent propeller group 7 comprises an independent propeller group fixing frame and a third water-jet propeller, and the third water-jet propeller is fixed on the bottom surface of the device shell 1 through the independent propeller group fixing frame.
The lifting mechanism comprises a sliding rail 3, a sliding block 4, an electromagnet 9 and a limiting device 5, wherein the sliding rail 3 is fixed on the inner side wall of a device shell, the electromagnet 9 is fixed on the top surface of an upper cover 10 of the device shell 1, the vertical position of the electromagnet is opposite to the sliding rail 3, a combined propeller group 8 is connected with the sliding block 4 through a waterproof steering engine 2, the sliding block 4 moves along the sliding rail 3 in the vertical direction, and the limiting device 5 is arranged at the lower end of the sliding rail 3 and is fixedly connected with the device shell 1.
The device shell 1 can be installed on amphibious vehicle bodies which can be matched with each other according to specific requirements, is symmetrically distributed along the longitudinal axis of the vehicle body and bears the water propulsion task of an amphibious combat platform. The independent propeller group 7 and the first water spraying propeller 6 are arranged at the position close to the axis, are positioned below the whole space, the combined propeller group 8 is respectively arranged at the left side and the right side close to the device shell 1, and is connected with the sliding block 4 through the water discharging steering engine 2, moves on the sliding rail 3, and mechanically limits the movement of the sliding block 4 by using nuts. The four waterproof steering engines 2 control the independent propeller groups 7, the first water spraying propellers 6 and the combined propeller groups 8 to rotate in a vertical plane, and the position of the sliding block 4 is moved by combining the action of the electromagnet 9 above the sliding rail 3 to finish the conversion of the array form.
With reference to fig. 3, when the amphibious warfare platform is in the land running state, the propulsion device of the invention is wholly in the device housing 1, and no influence is caused on the land running performance.
After Liu Shuizhuang state conversion task is issued, the propulsion device can convert the array form, firstly, in combination with fig. 4, the two water-discharging steering engines 2 at the lower part in rotation rotate the independent propulsion device 7 from the horizontal position to the vertical working position, and simultaneously, space is provided for the rotation of the combined propulsion device 8 at the left side and the right side.
When Liu Shuizhuang is switched, the electromagnet 9 is electrified in combination with fig. 5, and the sliding block 4 is sucked to the upper limit by the lower limit of the sliding rail 3, so that the water-discharging steering engine 2 rotates the combined propeller group 8 to the working position.
When Liu Shuizhuang is converted, the left and right waterproof steering engines 2 rotate in combination with fig. 6, and the combined propeller group 8 is placed in a vertical working position.
When Liu Shuizhuang is converted, the magnetism of the electromagnet 9 is reduced by combining with fig. 7, the sliding block 4 is slowly lowered to the lower mechanical limit, and the working state of water propulsion is converted.
The invention can improve the movement performance of the vehicle body on water, and in the structural design, the combined propeller groups 8 positioned at the left side and the right side increase the freedom degrees in two directions: firstly, the degree of freedom of movement in the vertical direction can change the working position of the combined propeller group 8 on the left side and the right side in the vertical direction according to different amphibious platform combat tasks and the wading environments by changing the lower mechanical limit of the sliding rail 3; secondly, the steering engine 2 rotates, the working positions of the combined thruster groups 8 at the two sides are not necessarily vertically downward at any time, and if wind waves are encountered during the movement on water, the angle of the steering engine 2 can be adjusted at any time, so that the working positions of the combined thruster groups 8 at the two sides are changed. The rotating steering engine 2 changes the degree of freedom of the combined propeller group 8, so that not only can the thrust line of the whole propulsion device be changed, but also the action moment of each propeller group on the vehicle body can be changed, thereby improving the accuracy of the vehicle body direction control, and having stronger adaptability to complex motion environments. More importantly, the change of the degree of freedom can be performed in real time, and the steering engine angle can be adjusted at any time by means of instructions of an operator during navigation.
The propulsion device designed by the invention needs to work under the water surface, and besides the waterproof work of the propulsion device, the waterproof effect of the mechanical structure self utilized by array change and the reliability and stability of the work on the water are considered. In consideration of the factors, the driving structure adopted by the invention consists of a waterproof steering engine and a slide rail and a slide block coated with protective paint. Although the electromagnet driving mode is greatly influenced by the circuit current factor, the advantage of the electromagnet driving sliding block is more remarkable compared with the mode of driving by using a lead screw or a linear motor because the sliding block is simple to move and the magnetic attraction state does not need to be maintained for a long time.
