Abstract
The utility model relates to a hovercraft with a water curtain wall. The hovercraft with the water curtain wall comprises a hovercraft body, and is characterized in that a pipe is arranged downwards behind a fan and penetrates the hovercraft body and an air chamber under the hovercraft body into water. When the hovercraft works, the air chamber is filled up with high-pressure air to jack up the hovercraft body, the water passes upwards through the pipe and is sprayed at the opening of the fan to form the water curtain wall, and air from the fan is blown onto the water curtain wall to form a counter force to make hovercraft move forward.
Description
Technical field
The utility model belongs to a kind of new application engineering with vertically upward spraying Water curtain wall and increase on the air cushion vehicle of air screw blower fan antagonistic force method, relates in particular to a kind of air cushion vehicle with Water curtain wall.
Background technology
Air cushion vehicle is to utilize high pressure air alow, form air cushion between the water surface or ground, makes all or part of the hovering of hull and realizes the ship of navigation at a high speed; Air cushion is with high-power blowing engine, air to be pressed under hull bottom, limits its effusion form by the hull bottom air seal set such as flexible skirt or rigid sidewalls around; Due to positice ground effect away from the water surface, ground and floating, the friction force on hull and the water surface or ground is almost nil, therefore has unique amphibious property and rapidity preferably; Adopt air screw, utilize the side-force reaction of gas, make hull be able to front, rear, left and right motion, air cushion vehicle is a kind of novel traffic carrier that uses air cushion technology to reduce resistance, raising speed; And the air that the air that air screw blower fan blows out promotes below just forms the reason that antagonistic force advances hull, but because the resistance of air is little, therefore cause waste and the slow-footed defect of air screw blower fan outputting power.
Utility model content
In order to improve above-mentioned defect, the utility model has designed and has a kind ofly allowed air screw blower fan blow to Water curtain wall to increase the mode of pressure, thereby reaches the technology that increases the antagonistic force of air screw blower fan and improve route speed.The technical solution of the utility model is:
A kind of air cushion vehicle with Water curtain wall, comprise hull, it is characterized in that air screw blower fan rear portion is to having pipeline, pipeline enters in water through the air chamber of hull and bottom, in work, in air chamber, be full of anticyclonic pressure jack-up hull, by pipeline, upwards at air screw blower fan rear portion, ejection forms water curtain to water, and air screw blower fan blows and on water curtain, forms antagonistic force, this antagonistic force is greater than situation about not having on Water curtain wall, has produced the extra power that allows air cushion vehicle advance.
Described pipeline is rectangular tube or comb, and the water outlet on top is arranged on below the air outlet rear portion of blower fan, and the water inlet of pipeline bottom protrudes air chamber apron 10-20cm around; Pipeline is sleeve pipe, and being arranged at section of tubing in air chamber can up-down adjustment, and described regulating mechanism is automatically to regulate, and switch is arranged at operator's compartment; This pipeline, in the time that air cushion vehicle arrives hard surface as ground, sandy beach or meadow, automatic retraction, breakage while preventing from contacting hard surface.
Further, in described pipeline, be provided with valve, valve is electromagnetic valve, and operator's compartment is provided with the master cock of this valve, closes pipeline leaving after the water surface, prevents the reduction of bottom air pressure.
The manufacture method of the described air cushion vehicle with Water curtain wall, its feature comprises the steps: to provide hull, and the comb of rectangular tube or row's circular pipe composition is set downwards at blower fan rear portion, and pipeline is provided with valve, valve is electromagnetic valve, and the master cock of this valve is set at operator's compartment; Pipeline is sleeve pipe, is arranged on the section of tubing in air chamber automatic adjusting mechanism is set, and this regulating mechanism switch is arranged on operator's compartment; The water outlet of conduit upper is arranged on the air outlet downside of blower fan, and the water inlet of pipeline bottom protrudes air chamber apron 10-20cm around; In work, in air chamber, be full of anticyclonic pressure jack-up hull, water upwards forms Water curtain wall in the ejection of blower fan mouth by pipeline, and blower fan blows and on water curtain, forms antagonistic force, and the power that air cushion vehicle advances is increased.
The utility model has the advantages that:
Because to blow water curtain large than the resistance/pressure that blows air for blower fan under equal rotating speed, so antagonistic force strengthens, make the speed quickening of air cushion vehicle, both can saving fuel, raising speed can also save time; Because pipeline of the present utility model is sleeve pipe, the pipeline of bottom protrudes the degree of depth and can regulate, and does not therefore change the feature of air cushion vehicle as amphibious use again.

Wherein: 1. blower fan, 2. pipeline, 3. hull, 4. apron, 5. water inlet, 6. water curtain, the 7. water surface.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
The specific embodiment
Embodiment: as shown in Figure 1,2,3, 4, this air cushion vehicle with Water curtain wall, it is characterized in that air screw blower fan 1 rear portion is to having pipeline 2, if multi fan 1 air cushion vehicle, can arrange pipeline 2 at each blower fan 1 rear portion, pipeline 2 enters in water through the air chamber of hull 3 and bottom, in work, in air chamber, be full of anticyclonic pressure jack-up hull 3, water upwards forms water curtain 6 in the ejection of blower fan mouth by pipeline 2, and blower fan 1 blows on water curtain 6 and forms antagonistic force, increases the power that air cushion vehicle advances.
In order to increase blowing area, pipeline 2 is designed to rectangular tube, can be also the comb of several round tube compositions, and the water outlet on top is arranged on the air outlet downside of blower fan 1, and the water inlet 5 of bottom protrudes air chamber apron 4 certain distances around, general 10-20cm.
Further, the function that can travel on land in order to reach air cushion vehicle, is designed to sleeve pipe described pipeline 2, being arranged at section of tubing 2 in air chamber can up-down adjustment, described regulating mechanism is automatically to regulate, and to prevent pipeline touching ground, switch is arranged at operator's compartment.
The manufacture method of the described air cushion vehicle with Water curtain wall, its feature comprises the steps: to provide hull 3, and the comb of rectangular duct 2 or several round tube composition is set downwards at blower fan 1 rear portion, in pipeline 2, is provided with valve, valve is electromagnetic valve, and the master cock of this valve is set at operator's compartment; Pipeline 2 is sleeve pipe, is arranged on the section of tubing 2 in air chamber automatic adjusting mechanism is set, and this regulating mechanism switch is arranged on operator's compartment; The water outlet on pipeline 2 tops is arranged on the air outlet downside of blower fan 1, and the water inlet 5 of pipeline 2 bottoms protrudes air chamber apron certain distance around, lower than the following 10-20cm of the water surface 7; In work, in air chamber, be full of anticyclonic pressure jack-up hull 3, water upwards forms water curtain 6 in 1 mouthful of ejection of blower fan by pipeline 2, and blower fan 1 blows on water curtain 6 and forms antagonistic force, and air cushion vehicle advances.
Air cushion vehicle with Water curtain wall of the present utility model, travels at the water surface, thereby increases resistance or pressure because blower fan blows to water curtain, and antagonistic force is increased, and has the advantage of saving fuel, raising speed, can also save time; And in the time of land locomotion, as long as regulate duct height to use.
