The invention aims to provide a double-air cushion type air cushion ship with convenient sampling and high safety so as to avoid the occurrence of ship body overturning caused by adoption.
The utility model provides a two air cushion type air cushion ship, including the ship body, the left and right sides of ship body bottom is provided with the plenum chamber that the periphery had flexible apron to surround respectively, then install the screw at the rear side of ship body, and the guide duct in the screw outside, the end of giving vent to anger of screw then is provided with the guide duct inner tube that cup joints in the guide duct hollow, form the wind-guiding cavity between guide duct and the guide duct inner tube, the tail end of wind-guiding cavity passes through the baffle with guide duct and be connected the shutoff of wind-guiding inner tube, the plenum chamber of both sides is connected respectively through two wind channels of ship body in the bottom of wind-guiding cavity, still be provided with the sampling channel that runs through the hull between two plenum chambers in the middle part of ship body.
The invention relates to a double-air cushion type air cushion ship, which is characterized in that the left side and the right side of the bottom of a ship body are respectively provided with a plenum chamber surrounded by flexible aprons, and air flow is discharged outwards by driving a propeller to rotate towards the direction of an air guide inner pipe at an air outlet end, part of the discharged air flow is blown into an air guide cavity between an air guide pipe and the air guide inner pipe, and the air guide cavity is blown to the plenums at the two sides of the bottom of the ship body through an air duct so as to provide upward cushion lifting force for a ship body; the other part of air flow blows to the wind guide inner pipe, so that forward thrust can be provided for the hovercraft, and the hovercraft can move forward more quickly; the wind power discharged by the propeller is directly communicated with the pressurizing chamber through the two air passages of the ship body, so that the lifting force of the pressurizing chamber air is more balanced, and the running process of the ship body is more stable; because the lift force of the ship body is provided by the pressurizing chambers at two sides of the bottom of the ship body, when special sections such as swamps, beaches and the like are required to carry out geological sampling and detection work, sampling equipment can be directly put down through a sampling channel penetrating through the ship body between the two pressurizing chambers, so that the geological sampling and detection can be realized, and the risk that the ship body gravity center is unstable and capsizes is caused because the sampling equipment needs to be carried to one side of the ship body by the traditional air cushion ship is avoided. Meanwhile, the air guide cavity is connected with the air duct to form a pressurizing cavity, so that air tightness is enhanced, frictional resistance between the air cushion ship and the water surface is reduced, energy consumption is reduced, and speed is improved. Because the flexible apron at the bottom of the air cushion ship can reduce the contact between water and the ship body, vibration and noise can be effectively reduced, the ship can run more stably and quietly, and the comfort level of passengers is improved.

Description of the embodiments
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that, in the embodiment of the present invention, directional indications (such as up, down, left, right, front, rear, top, bottom, inner, outer, vertical, lateral, longitudinal, counterclockwise, clockwise, circumferential, radial, axial … …) are referred to, and the directional indications are merely used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.
In addition, if there is a description of "first" or "second" etc. in the embodiments of the present invention, the description of "first" or "second" etc. is only for descriptive purposes, and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
As shown in fig. 1-5, the double-air cushion all-lift air cushion ship comprises a ship body 1, wherein the left side and the right side of the bottom of the ship body 1 are respectively provided with a pressurizing chamber 3 surrounded by a flexible apron 2, the rear side of the ship body 1 is provided with a screw propeller 12 and an air guide pipe 6 sleeved outside the screw propeller 12, the air outlet end of the screw propeller 12 is provided with an air guide inner pipe 7 sleeved in the air guide pipe 6, an air guide chamber 8 is formed between the air guide pipe 6 and the air guide inner pipe 7, the tail end of the air guide chamber 8 is used for blocking and connecting the air guide pipe 6 with the air guide inner pipe 7 through a baffle 9, the bottom of the air guide chamber 8 is respectively connected with the pressurizing chambers 3 at two sides through two air channels 4 of the ship body 1, and a sampling channel 5 penetrating through a ship body is further arranged between the two pressurizing chambers 3 in the middle of the ship body 1.
As shown in fig. 3 and 4, the air duct 4 at the top of the pressurizing chamber 3 has an inverted trapezoid structure; the two sides of the inverted trapezoid air duct 4 are provided with air outlets 10 towards the flexible apron 2; the air outlet holes facing the flexible apron can enable air flow to be uniformly sprayed to two sides of the flexible apron from the side faces, so that uniform air discharge of the air cushion is facilitated, downward lifting of the flexible apron is balanced, and stability of the ship body on the water surface is improved.
As shown in fig. 5, the air outlet holes 10 far from the air guiding chamber 8 are sequentially reduced. When the air outlet holes are smaller, the corresponding air flow pressure is higher, and additional lifting force can be provided, so that the front end of the ship body is lifted, and the advancing stability is improved. When the air outlet holes are larger, the corresponding air flow pressure is lower, so that the lifting force can be reduced, and the ship body can maintain a relatively stable horizontal posture. The air outlet holes far away from the air guide cavity are gradually reduced, so that different pressure distributions can be formed on the bottom of the air cushion by the air flow. Thus, the attitude and balance of the air cushion ship can be adjusted.
As shown in fig. 1 and 2, the air outlet end of the propeller 12 is provided with a control blade 11 for controlling the air flow direction. The control blade can control the direction of the air outlet of the propeller, so that the hovercraft can run on the water surface more flexibly, the stability of the hovercraft is improved, and the maneuvering performance is improved.
The flexible apron 2 is a full-finger apron. When the hovercraft surveys and samples in the marsh and muddy areas, the whole finger apron can be evenly distributed and bear the load on the ship, and the structural stability of the ship is enhanced. Through the shape and the pressure distribution of effective control air cushion, indicate the apron entirely can provide more even buoyancy support, makes the ship more stable on the surface of water.
