Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship carrying equipment, in particular to a ground effect wing ship multi-navigation state adjusting device and method. BACKGROUND

[0002] The ground effect wing ship is a kind of tri-service special high-speed ship that can navigate on water, land and air. It can cruise in the form of super-low altitude water-skiing flight, and can also realize high-altitude flight like an airplane and water navigation like a ship. The ground effect wing ship relies on the wing lift to lift the ship out of the water surface during takeoff. The lift increases with the increase of the navigation speed. When the load is large, the ship body is difficult to separate from the water surface, and the water resistance cannot be improved, so the lift cannot be increased, which makes it difficult for the ground effect wing ship to take off. At the same time, the increase of the water surface speed increases the wave load on the ship body, which may damage the ship body structure. If other external force supports the ship body at this time, the ground effect wing ship can complete the takeoff at low speed. The conventional ground effect wing ship only relies on the air propeller to provide power, and the water surface turning relies on the differential speed of the two air propellers to realize, and the turning radius is large, which is easy to collide with other ships or the river channel in the narrow river channel, and it is difficult to realize water surface turning. When only a single engine is used in the ground effect wing ship, water surface turning cannot be realized. The ground effect wing ship is usually equipped with an aero-engine and a one-way air propeller, which cannot provide reverse thrust to realize rapid water surface braking of the ground effect wing ship. Only by closing the engine can the ground effect wing ship rely on water resistance to slow down slowly. However, in order to facilitate takeoff, the bottom of the ground effect wing ship is designed to be a streamlined shape with very small resistance, and the braking effect is very poor only by relying on water resistance. Collision is easy to occur in a narrow river channel. The ground effect wing ship often needs to be overhauled and loaded with goods on the shore, and needs to rely on the landing wheel system to land on the shore and drive on the road. The traditional hydraulic brake and steering system is too heavy and is not suitable for the landing wheel system of the ground effect wing ship. In summary, the water surface takeoff, water surface turning, water surface braking and land braking of the ground effect wing ship are all limited and cannot be quickly realized. If the water navigation, takeoff and land driving and other multi-navigation state can be adjusted in time, the navigation performance of the ground effect wing ship will be greatly improved.

[0003] Therefore, the ground effect wing ship multi-navigation state adjusting device and method are proposed. SUMMARY

[0031] The application also discloses a ground effect wing boat multi-navigation state adjusting method, when the ground effect wing boat takes off on water, the engine is in a high-power state, and the engine speed measuring switch KSnb connected with the water take-off electromagnetic valve YV5 is closed; in order to make the ground effect wing boat take off from water at a small speed, when the navigation speed reaches half of the take-off speed, the take-off plate extending switch SA9 is stepped on, the DC motor is energized to work, the hydraulic oil is injected into the take-off cylinder through the one-way valve and the water take-off electromagnetic valve YV5, the pull rod of the take-off cylinder is retracted, the take-off plate is driven to extend around the rotary shaft thereof, until the take-off plate is at an angle of 25° with the water surface, the pull rod of the take-off cylinder is retracted to zero position; at this time, when the ground effect wing boat drives forward, the water generates an oblique upward thrust on the plane of the take-off plate, and the ground effect wing boat is lifted from water; after the ground effect wing boat finishes taking off, the take-off plate extending from the body of the ground effect wing boat increases the flight resistance, therefore, the take-off plate retracting switch SA10 is stepped on, the water take-off electromagnetic valve YV5 and the unloading pressure electromagnetic valve YV6 are opened, the hydraulic oil flows back to the oil tank, and the pull rod of the take-off cylinder extends under the action of the internal spring, so that the take-off plate is retracted to a position parallel to the bottom of the body of the ground effect wing boat;

[0032] When the wing-in-ground craft turns on water surface, the engine is in low speed state, and the engine speed switch KSna connected with the left water brake electromagnetic valve YV3 and the right water brake electromagnetic valve YV4 in series is closed; when the wing-in-ground craft turns left on water surface, the left brake plate front extension switch SA5 is stepped down, the DC motor works, the left water brake electromagnetic valve YV3 is opened, the hydraulic oil is injected into the left brake cylinder through the one-way valve and the left water brake electromagnetic valve YV, the pull rod of the left brake cylinder is contracted, the left brake plate is rotated to be perpendicular to the bottom of the ship body, the left resistance is increased, so that the water surface turns left; after the left turning is completed, the left brake plate retraction switch SA6 is stepped down, the left water brake electromagnetic valve YV3 and the pressure relief electromagnetic valve YV6 are opened, the hydraulic oil flows back to the oil tank, the pull rod of the left brake cylinder is extended under the action of the internal spring, and the left brake plate returns to the parallel state with the bottom of the ship body; the principle of turning right on water surface is the same as that of turning left on water surface;

[0033] When the wing-in-ground craft brakes on water surface, the two engines are in closed state, and the engine speed switch KSna connected with the left water brake electromagnetic valve YV3 and the right water brake electromagnetic valve YV4 in series is closed; at the same time, the left brake plate front extension switch SA5 and the right brake plate front extension switch SA7 are stepped down, the hydraulic oil is injected into the left brake cylinder and the right brake cylinder at the same time, the left brake plate and the right brake plate are perpendicular to the bottom of the ship body at the same time, the resistance generated by the two brake plates can make the wing-in-ground craft decelerate quickly, so that the water surface braking purpose is achieved;

[0034] When the wing-in-ground craft drives on land, the engine is in idle speed or off state, and the engine speed switch KSna connected with the left land brake electromagnetic valve YV1 and the right land brake electromagnetic valve YV2 in series is closed; the wing-in-ground craft turns on land by relying on unilateral brake, the left brake is needed when turning left, the left land brake switch SA1 is stepped down, the DC motor works, the left brake electromagnetic valve YV1 is closed, the hydraulic oil enters the left brake disc through the one-way valve, the throttle valve and the left brake electromagnetic valve YV1, when the left land pressure relief switch SA2 is stepped down, the left brake electromagnetic valve YV1 and the pressure relief electromagnetic valve YV6 are closed, the hydraulic oil in the left brake disc flows back to the oil tank through the left brake electromagnetic valve YV1 and the pressure relief electromagnetic valve YV6, and the left brake is released; the principle of right unilateral brake is the same as that of left unilateral brake; when the two sides brake together, the left land brake switch SA1 and the right land brake switch SA3 are stepped down at the same time, the DC motor works, the left brake electromagnetic valve YV1 and the right brake electromagnetic valve YV2 are closed, and the hydraulic oil flows to the left brake disc and the right brake disc at the same time; after the left land brake switch SA1 and the right land brake switch SA3 are released, the left brake disc and the right brake disc still maintain the set oil pressure; if unilateral pressure relief is needed, unilateral foot switch is stepped down, if two sides pressure relief is needed, the left land pressure relief switch SA2 and the right land pressure relief switch SA4 are stepped down at the same time;

[0035] When the ground effect wing boat brakes, if the oil pressure in the brake disc is always maintained, there will be a clear jerk feeling at the moment when it is about to stop, which not only brings a poor experience to the driver and passengers, but also generates a great impact force at the connecting part of the landing wheel and the body structure, which is easy to cause structural damage. The left wheel speed switch KS1 and the right wheel speed switch KS2 can measure the speed of the left landing wheel and the right landing wheel at any time. When the speed is less than the set speed, the left wheel speed switch KS1 and the right wheel speed switch KS2 are connected, the left brake electromagnetic valve YV1, the right brake electromagnetic valve YV2 and the pressure relief electromagnetic valve YV6 are closed, the hydraulic oil in the left brake disc and the right brake disc flows back to the oil tank, and the pressure relief purpose is completed. At this time, the ground effect wing boat stops slowly relying on the ground friction, so as to eliminate the brake jerk.

[0036] The beneficial effects of the present application are as follows:

[0037] The present application has the advantages that the structure is compact and reasonable, and the operation is convenient. A single hydraulic oil pump supplies oil to the take-off oil cylinder, the left brake oil cylinder, the right brake oil cylinder, the left brake disc and the right brake disc, and the take-off plate, the left brake plate, the right brake plate, the left brake disc and the right brake disc are controlled separately. During the take-off stage of the ground effect wing boat, the take-off plate can provide upward lifting force for the ground effect wing boat. When the ground effect wing boat turns on the water surface, a single brake plate can be controlled to stand up to increase the unilateral water resistance and cooperate with the differential of the engine to complete the turning. When the ground effect wing boat brakes on the water surface, the two brake plates can be controlled to stand up at the same time to increase the water resistance and complete the braking. When the ground effect wing boat brakes on land, the single or double brake disc can be controlled to complete the single or double braking on land, and the speed switches of the two groups respectively measure the speed of the left and right landing wheels. At the moment when the ground effect wing boat is about to stop, the single electromagnetic valve and the pressure relief electromagnetic valve YV6 are connected, the oil pressure of the brake disc is discharged back to the oil tank, the braking is more stable, and the impact of the landing wheel system on the structure of the ground effect wing boat is avoided.

[0038] Meanwhile, the present application also has the following advantages:

[0039] (1) By setting the throttle valve, the throttle valve adjusts the flow rate of the hydraulic oil in the hydraulic main pipeline, so as to control the time required to set the brake oil pressure. When the flow of the throttle valve is small, the time required to set the brake oil pressure is longer, the brake speed is slower, and the brake is softer. The driver can release the foot switch in time according to the situation, so that the actual brake oil pressure is less than the set brake oil pressure. When adjusting the flow of the throttle valve, the left land brake switch SA1 or the right land brake switch SA3 should be long pressed, and the left brake oil pressure table or the right brake oil pressure table should be observed to see how long it takes to reach the set oil pressure value. The larger the flow, the shorter the time required, and the smaller the flow, the longer the time required. The flow of the throttle valve should be set according to the brake distance requirement.

[0040] (2) By setting the overflow valve, the oil pressure in the hydraulic circuit reaches a certain value and no longer rises, to protect the pipeline and DC motor, the specific oil pressure regulating valve is overflow valve, when the pipeline is continuously pressurized to reach the set value of the overflow valve, the overflow valve is automatically opened, the hydraulic oil is directly returned to the tank through the overflow valve after the hydraulic oil pump, the pipeline is always kept at the set oil pressure of the overflow valve and no longer rises; The size of the set oil pressure can be determined according to the specifications of each oil cylinder and brake disc, when setting the maximum brake oil pressure, the left land brake switch SA1 or the right land brake switch SA3 should be long pressed, at this time the value of the left brake oil pressure gauge or the right brake oil pressure gauge is the set oil pressure value of the overflow valve.

[0041] (3) The ground effect wing ship multi-state adjustment device realizes the integration of ground effect wing ship water surface take-off assistance, water surface turning, water surface braking and land stable braking control, and does not damage the take-off sliding surface, so that the ground effect wing ship multi-state adjustment is completed with small weight.

[0042] (4) When the ground effect wing ship is braking, if the oil pressure in the brake disc is always maintained, there will be a clear jerk feeling at the moment of stopping, which not only brings a poor experience to the driver and passengers, but also generates a great impact force at the connection part of the landing wheel and the ship structure, which is easy to cause structural damage. The left wheel speed switch KS1 and the right wheel speed switch KS2 can measure the speed of the left landing wheel and the right landing wheel at any time, when the speed is less than the set speed, the left wheel speed switch KS1 and the right wheel speed switch KS2 are connected, the left brake electromagnetic valve YV1, the right brake electromagnetic valve YV2 and the pressure relief electromagnetic valve YV6 are closed, the hydraulic oil in the left brake disc and the right brake disc flows back to the tank, and the pressure relief purpose is achieved, at this time the ground effect wing ship stops slowly relying on the ground friction, so as to eliminate the brake jerk.

[0065] The throttle valve 7 adjusts the flow rate of hydraulic oil in the main hydraulic line, so as to control the time required to reach the set brake oil pressure. When the flow of the throttle valve 7 is small, it takes longer to reach the set brake oil pressure, the brake is slower, and the brake is softer. The driver can release the foot switch in time according to the situation, so that the actual brake oil pressure is less than the set brake oil pressure. When adjusting the flow of the throttle valve 7, the left land brake switch SA1 or the right land brake switch SA3 should be pressed for a long time. The time required to reach the set oil pressure value of the left brake oil pressure gauge 11 or the right brake oil pressure gauge 14 is short when the flow is large, and the time required is long when the flow is small. The flow of the throttle valve 7 should be set according to the brake distance requirement.

[0066] When the oil pressure in the hydraulic line reaches a certain value and no longer rises, the line and the DC motor 3 are protected. The specific oil pressure regulating valve is the overflow valve 6. When the pressure in the line continuously increases to the set value of the overflow valve 6, the overflow valve 6 automatically opens, and the hydraulic oil flows back to the oil tank 1 through the overflow valve 6 after passing through the hydraulic oil pump 4. The line always maintains the set oil pressure of the overflow valve 6 and no longer rises. The size of the set oil pressure can be determined according to the specifications of each oil cylinder and brake disc. When the maximum brake oil pressure is set, the left land brake switch SA1 or the right land brake switch SA3 should be pressed for a long time. At this time, the value of the left brake oil pressure gauge 11 or the right brake oil pressure gauge 14 is the set oil pressure value of the overflow valve 6.

[0067] The ground effect wing ship has multiple flight state adjustment methods. When the ground effect wing ship takes off on the water surface, the engine is in a high-power state, and the engine speed measuring switch KS connected in series with the water take-off electromagnetic valve YV5 is closed. In order to make the ground effect wing ship take off from the water at a small speed, when the sailing speed reaches half of the take-off speed, the take-off plate forward extension switch SA9 is pressed with the foot, the DC motor 3 is energized to work, the hydraulic oil is injected into the take-off cylinder 8 through the one-way valve 5 and the water take-off electromagnetic valve YV5, the pull rod of the take-off cylinder 8 is retracted, the take-off plate 17 is driven to rotate around its rotary shaft to extend forward, and when the take-off plate 17 is at an angle of 25° with the water surface, the pull rod of the take-off cylinder 8 is retracted to zero position. At this time, when the ground effect wing ship moves forward, the water on the plane of the take-off plate 17 generates an upward thrust, which lifts the ground effect wing ship from the water. After the ground effect wing ship completes take-off, the take-off plate 17 extending from the ship body will increase the flight resistance, so the take-off plate retraction switch SA10 should be pressed with the foot, the water take-off electromagnetic valve YV5 and the pressure relief electromagnetic valve YV6 are opened, the hydraulic oil flows back to the oil tank 1, and the take-off cylinder 8 extends the pull rod under the action of the internal spring to retract the take-off plate 17 to a position parallel to the bottom of the ship body.

[0068] When the wing-in-ground craft turns on water surface, the engine is in low speed state, and the engine speed measuring switch KS connected with the left water brake electromagnetic valve YV3 and the right water brake electromagnetic valve YV4 in series is closed. When the wing-in-ground craft turns left on water surface, the left brake plate front extension switch SA5 is stepped down, the direct current motor 3 works, the left water brake electromagnetic valve YV3 is opened, the hydraulic oil is injected into the left brake oil cylinder 9 through the one-way valve 5 and the left water brake electromagnetic valve YV, the pull rod of the left brake oil cylinder 9 is contracted, the left brake plate 18 is rotated to be perpendicular to the bottom of the ship body, the left resistance is increased, so that the turning left on water surface is realized; at this time, the wing-in-ground craft with double engines can increase the speed of the right engine, so that the right thrust of the wing-in-ground craft is increased, and the turning left is accelerated. After the turning left is completed, the left brake plate retraction switch SA6 is stepped down, the left water brake electromagnetic valve YV3 and the pressure relief electromagnetic valve YV6 are opened, the hydraulic oil flows back to the oil tank 1, the pull rod of the left brake oil cylinder 9 is extended under the action of the internal spring, and the left brake plate 18 returns to the parallel state with the bottom of the ship body. The principle is the same when the wing-in-ground craft turns right on water surface.

[0069] When the wing-in-ground craft brakes on water surface, the two engines are in closed state, and the engine speed measuring switch KS connected with the left water brake electromagnetic valve YV3 and the right water brake electromagnetic valve YV4 in series is closed. At the same time, the left brake plate front extension switch SA5 and the right brake plate front extension switch SA7 are stepped down, the hydraulic oil is injected into the left brake oil cylinder 9 and the right brake oil cylinder 10 at the same time, the left brake plate 18 and the right brake plate 19 are perpendicular to the bottom of the ship body at the same time, the resistance generated by the two brake plates can make the wing-in-ground craft decelerate quickly, so that the purpose of braking on water surface is realized.

[0070] When the wing-in-ground effect vehicle is running on land, the engine is in idle or off state, and the engine speed sensor switch KS connected in series with the left land brake solenoid YV1 and the right land brake solenoid YV2 is closed. The wing-in-ground effect vehicle without steering system relies on unilateral brake to turn on land. When turning left, the left unilateral brake is needed, the left land brake switch SA1 is stepped on, the direct current motor 3 works, the left brake solenoid YV1 is closed, and the hydraulic oil enters the left brake disc 12 through the one-way valve 5, the throttle valve 7 and the left brake solenoid YV1. When the left land pressure relief switch SA2 is stepped on, the left brake solenoid YV1 and the pressure relief solenoid YV6 are closed, the hydraulic oil in the left brake disc 12 flows back to the oil tank 1 through the left brake solenoid YV1 and the pressure relief solenoid YV6, and the left brake is released. The right unilateral brake has the same principle as the left unilateral brake. When braking on both sides, the left land brake switch SA1 and the right land brake switch SA3 are stepped on at the same time, the direct current motor 3 works, the left brake solenoid YV1 and the right brake solenoid YV2 are closed, and the hydraulic oil flows to the left brake disc 12 and the right brake disc 15 at the same time. After the left land brake switch SA1 and the right land brake switch SA3 are released, the left brake disc 12 and the right brake disc 15 still maintain the set oil pressure. If unilateral pressure relief is needed, the unilateral foot pedal switch is stepped on, and if both sides are needed to be relieved at the same time, the left land pressure relief switch SA2 and the right land pressure relief switch SA4 are stepped on at the same time.

[0071] When the wing-in-ground effect vehicle is braking, if the oil pressure in the brake disc is always maintained, there will be a clear jerk at the moment when it is about to stop, which not only brings a poor experience to the driver and passengers, but also generates a great impact force at the connection part between the landing wheel and the ship structure, which is easy to cause structural damage. The left wheel speed sensor switch KS1 and the right wheel speed sensor switch KS2 can measure the speed of the left landing wheel 13 and the right landing wheel 16 at any time, when the speed is less than the set speed, the left wheel speed sensor switch KS1 and the right wheel speed sensor switch KS2 are connected, the left brake solenoid YV1, the right brake solenoid YV2 and the pressure relief solenoid YV6 are closed, the hydraulic oil in the left brake disc 12 and the right brake disc 15 flows back to the oil tank 1, and the pressure relief purpose is achieved. At this time, the wing-in-ground effect vehicle relies on the friction force of the ground to slow down, so as to eliminate the brake jerk.

[0072] The above description is an explanation of the application, not a limitation of the application, the scope of the application is defined in the claims, within the protection scope of the application, any form of modification can be made.

The method of adjusting multiple flight modes of a ground effect wing craft, using the device for adjusting multiple flight modes of a ground effect wing craft as claimed in claim 1, wherein: When the wing-in-ground craft takes off from water, the engine is in high-power state, and the engine speed measuring switch KSnb in series with the water take-off electromagnetic valve YV5 is closed; in order to make the wing-in-ground craft take off from water at a small speed, when the sailing speed reaches half of the take-off speed, the take-off board forward stretching switch SA9 is stepped on, the DC motor (3) is energized to work, the hydraulic oil is injected into the take-off oil cylinder (8) through the one-way valve (5) and the water take-off electromagnetic valve YV5, the pull rod of the take-off oil cylinder (8) is retracted, the take-off board (17) is driven to rotate around the rotary shaft thereof and forwardly stretched until the take-off board (17) is at an angle of 25° with the water surface, and the pull rod of the take-off oil cylinder (8) is retracted to zero position; at this time, when the wing-in-ground craft moves forward, the water produces an oblique upward thrust on the plane of the take-off board (17), and the wing-in-ground craft is lifted from the water; after the wing-in-ground craft completes take-off, the take-off board (17) stretched out of the body increases the flight resistance, therefore, the take-off board retraction switch SA10 is stepped on, the water take-off electromagnetic valve YV5 and the pressure relief electromagnetic valve YV6 are opened, the hydraulic oil flows back to the oil tank (1), and the take-off oil cylinder (8) is forwardly stretched under the action of the internal spring, and the take-off board (17) is retracted to a position parallel to the bottom of the body; When the wing-in-ground craft turns on water, the engine is in low-power state, and the engine speed measuring switch KSna in series with the left water brake electromagnetic valve YV3 and the right water brake electromagnetic valve YV4 is closed; when the wing-in-ground craft turns left on water, the left brake board forward stretching switch SA5 is stepped on, the DC motor (3) works, the left water brake electromagnetic valve YV3 is opened, the hydraulic oil is injected into the left brake oil cylinder (9) through the one-way valve (5) and the left water brake electromagnetic valve YV, the pull rod of the left brake oil cylinder (9) is retracted, the left brake board (18) is rotated to be perpendicular to the bottom of the body, the left resistance is increased, and the water turns left is realized; after the left turn is completed, the left brake board retraction switch SA6 is stepped on, the left water brake electromagnetic valve YV3 and the pressure relief electromagnetic valve YV6 are opened, the hydraulic oil flows back to the oil tank (1), the pull rod of the left brake oil cylinder (9) is forwardly stretched under the action of the internal spring, and the left brake board (18) returns to a state parallel to the bottom of the body; the principle is the same when the wing-in-ground craft turns right on water; When the wing-in-ground craft brakes on water, the two engines are in closed state, the engine speed measuring switch KSna in series with the left water brake electromagnetic valve YV3 and the right water brake electromagnetic valve YV4 is closed; meanwhile, the left brake board forward stretching switch SA5 and the right brake board forward stretching switch SA7 are stepped on, the hydraulic oil is injected into the left brake oil cylinder (9) and the right brake oil cylinder (10) at the same time, the left brake board (18) and the right brake board (19) are perpendicular to the bottom of the body at the same time, the resistance generated by the two brake boards can make the wing-in-ground craft decelerate rapidly, and the water braking purpose is realized; When the wing-in-ground effect vehicle is running on land, the engine is in idle or off state, and the engine speed switch KSna connected in series with the left land brake solenoid YV1 and the right land brake solenoid YV2 is closed. The wing-in-ground effect vehicle without steering system relies on unilateral brake to turn on land. When turning left, the left unilateral brake is needed. The left land brake switch SA1 is pressed down, the DC motor (3) works, the left brake solenoid YV1 is closed, and the hydraulic oil enters the left brake disc (12) through the one-way valve (5), the throttle valve (7) and the left brake solenoid YV1. When the left land pressure relief switch SA2 is pressed down, the left brake solenoid YV1 and the pressure relief solenoid YV6 are closed, the hydraulic oil in the left brake disc (12) flows back to the oil tank (1) through the left brake solenoid YV1 and the pressure relief solenoid YV6, and the left brake is released. The right unilateral brake has the same principle as the left unilateral brake. When both sides are braked at the same time, the left land brake switch SA1 and the right land brake switch SA3 are pressed down at the same time, the DC motor (3) works, the left brake solenoid YV1 and the right brake solenoid YV2 are closed, and the hydraulic oil flows to the left brake disc (12) and the right brake disc (15) at the same time. After the left land brake switch SA1 and the right land brake switch SA3 are released, the left brake disc (12) and the right brake disc (15) still maintain the set oil pressure. If unilateral pressure relief is needed, unilateral foot pedal switch is pressed down. If both sides are relieved at the same time, the left land pressure relief switch SA2 and the right land pressure relief switch SA4 are pressed down at the same time. When the wing-in-ground effect vehicle is braked, if the oil pressure in the brake disc is always maintained, there will be a clear jerk at the moment when it is about to stop, which not only brings a poor experience to the driver and passengers, but also generates a great impact force at the connection part between the landing wheel and the hull structure, which is easy to cause structural damage. The left wheel speed switch KS1 and the right wheel speed switch KS2 can measure the speed of the left landing wheel (13) and the right landing wheel (16) at any time. When the speed is less than the set speed, the left wheel speed switch KS1 and the right wheel speed switch KS2 are connected, the left brake solenoid YV1, the right brake solenoid YV2 and the pressure relief solenoid YV6 are closed, the hydraulic oil in the left brake disc (12) and the right brake disc (15) flows back to the oil tank (1), and the pressure relief purpose is achieved. At this time, the wing-in-ground effect vehicle relies on the friction force of the ground to slow down, so as to eliminate the brake jerk.
