Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the present invention mainly comprises a hull 300, a front landing wheel module 100 is fixedly connected to a bottom end face of a front portion of the hull 300, rear landing wheel modules 200 are symmetrically arranged on left and right side end faces of a rear portion of the hull 300, and a connection line between the front landing wheel module 100 and the two rear landing wheel modules 200 forms an isosceles triangle.
As shown in fig. 2, the front landing wheel module 100 includes a cylinder 101, an upper flange 102 is fixedly connected to an upper portion of the cylinder 101, and a lower flange 103 is fixedly connected to a lower portion of the cylinder 101, wherein in use, the upper flange 102 is detachably connected to an inside of the hull 300 through a connector, and the lower flange 103 is detachably connected to a bottom of the hull 300 through a connector.
As shown in fig. 3, a telescopic tube 109 capable of sliding up and down is provided in the inner cavity of the cylinder 101, and a gap is provided between the telescopic tube 109 and the cylinder 101. The lower end of the extension tube 109 extends out of the cylinder 101 and is connected with a front wheel frame 110, and the front wheel frame 110 is rotatably connected with a front wheel 111 through a rotating shaft.
As shown in FIG. 3, the lower part of the inner surface of the cylinder 101 is fixedly connected with the lower limit sleeve 108, the outer surface of the extension tube 109 is fixedly connected with the upper limit sleeve 107, the upper end surface of the lower limit sleeve 108 can be connected with the lower end surface of the upper limit sleeve 107 in an inosculating way, and the extension tube 109 can be prevented from freely rotating in the cylinder 101 after the upper end surface of the lower limit sleeve 108 is connected with the lower end surface of the upper limit sleeve 107 in an inosculat.
As shown in fig. 3, the upper and lower portions of the inner surface of the cylinder 101 are fitted with sealing rings 106, respectively, and the sealing rings 106 are fitted to the outer surface of the extension tube 109 in an interference fit.
As shown in fig. 3, a plug 104 is disposed on the upper end surface of the extension tube 109, an air nozzle hole communicated with the inner cavity of the extension tube 109 is disposed on the plug 104, and an air nozzle 105 is connected to the air nozzle hole. An upper vent hole 112 which is internally and externally communicated is arranged at the upper part of the side wall of the extension tube 109, a lower vent hole 113 is arranged at the lower part of the side wall of the extension tube 109, external air enters the inner cavity of the extension tube 109 through the air nozzle 105 and then enters a gap between the extension tube 109 and the cylinder body 101 through the upper vent hole 112 and the lower vent hole 113, and the air pressure balance of the inner cavity of the cylinder body 101 is ensured.
As shown in fig. 3, a convex positioning table is arranged at the upper part of the extension tube 109, and a limiting plate is arranged at the side of the cylinder 101 and is located on the moving path of the positioning table. When the telescopic tube 109 drives the positioning table to move upwards, the positioning table is blocked by the limiting plate, and the top of the telescopic tube 109 is limited to extend out of the cylinder body 101.
When the air faucet 105 works, 0.2MPa of air pressure is introduced into the extension tube 109 and the cylinder body 101 through the air faucet 105, and the air pressure in the closed space is kept at 0.2MPa all the time by utilizing the one-way conduction principle of the air faucet 105. When the WIG craft lands, the front wheels 111, the front wheel frame 110, the telescopic pipe 109 and the upper limiting sleeve 107 move upwards together relative to the cylinder body 101 until the positioning table at the upper end of the telescopic pipe 109 leans against the limiting plate of the cylinder body 101, and the WIG craft stops moving upwards to provide support for the WIG craft. At this time, the lower limit sleeve 108 and the upper limit sleeve 107 are separated, the extension tube 109 can rotate on its own axis, and the front wheel 111 can rotate freely. The space between the lower limit sleeve 108 and the upper limit sleeve 107 is communicated with the inside of the extension tube 109 through the lower vent hole 113, so the air pressure is also 0.2MPa, when the WIG craft jolts in the land movement, the gas exchange is generated between the closed space between the lower limit sleeve 108 and the upper limit sleeve 107 and the closed space inside the extension tube 109, the gas exchange is realized only through the lower vent hole 113 below the extension tube 109, the gas circulation speed is slow, the up-and-down movement of the extension tube 109 lags behind the jolt of the WIG craft, and the buffer effect is achieved. When the WIG craft takes off, the front wheel 111, the front wheel frame 110, the telescopic pipe 109 and the upper limiting sleeve 107 move downwards together under the action of gravity, the telescopic pipe 109 rotates under the mutual action of the side walls of the upper limiting sleeve 107 and the lower limiting sleeve 108 in the moving-downwards process until the upper limiting sleeve 107 and the lower limiting sleeve 108 are completely meshed, at the moment, the rotation axis of the front wheel 111 is perpendicular to the flight direction of the WIG craft, and the front wheel 111 flies in the smallest windward area, so that the flight resistance is reduced. When the upper limit sleeve 107 and the lower limit sleeve 108 are completely engaged, the lower vent hole 113 at the lower end of the extension tube 109 is sealed by the lower limit sleeve 108, the upper limit sleeve 107 bears the pressure of the closed space of the cylindrical ring between the extension tube 109 and the cylinder body 101, the pressure is downward along the direction of the extension tube 109, the upper limit sleeve 107 and the lower limit sleeve 108 are tightly engaged under the combined action of air pressure and gravity, and the front wheel 111 is prevented from shaking up and down during the flight of the WIG craft to influence the flight stability.
