DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 3 As shown, an embodiment of the present application discloses a hydrofoil cavitation boat, comprising a hull 1 and a power assembly for driving the hull 1 to move, wherein wing structures 2 are symmetrically arranged on both sides of the hull 1, the wing structures 2 comprising a front wing structure and a rear wing structure having the same structure, and further comprising a cavitation system 3 arranged on both sides of the hull 1;

[0031] The front wing structure and the rear wing structure both include side wing panels 201. A side wing panel driving mechanism 202 for driving the side wing panels 201 to open or retract is provided in the hull 1. The side wing panels 201 are contoured structures. When the side wing panels 201 are in a retracted state, the side wing panels 201 conform to the hull.

[0032] Specifically, the hull 1 has a variety of navigation postures, such as completely floating on the sea surface, half submerged on the sea surface and completely submerged in the sea. When floating on the sponge and sailing, the side wing structures 2 on both sides of the hull 1 can be in an open state or a retracted state. When the side wing structures 2 are in an open state, the stability of the hull 1 during navigation can be ensured. When it is necessary to sail at the maximum speed on the water surface, the side wing plate driving mechanism 202 drives the side wing plates 201 to be in a retracted state, so that the side wing plates 201 are conformally fitted with the bottom of the hull. At this time, the side wing plates 201 do not leak out, that is, all structures of the hull 1 float on the sea surface. Under the drive of the power component, the hull 1 can run at the maximum speed. When the hull 1 is in a sneaking state, the side wing plate driving mechanism 202 drives the side wing plates 201 to maintain the stability of the hull 1, and the cavitation system 3 discharges cavitation gas to the outside of the hull 1 to reduce the side resistance of the hull 1. Under the drive of the power component, the hull 1 can run at the maximum speed.

[0033] In this structure, the hydrofoil structure is designed to be conformal with the bottom surface of the hull 1, so that the hull 1 can sail at the maximum speed when on the water surface. At the same time, the cavitation system 3 is designed in this structure, so that the hull 1 can sail at the maximum speed when it is in a submerged state.

[0034] In this embodiment, the side wing plate driving mechanism 202 includes an automatic telescopic rod 203, a driving end of the automatic telescopic rod 203 is connected to the side wing plate 201, and also includes a control mechanism for driving the automatic telescopic rod 203 to extend and retract.

[0035] Specifically, a roller 204 is provided at the front end of the driving end of the automatic telescopic rod 203, and a vertical groove 205 consistent with the movement direction of the driving end of the automatic telescopic rod 203 is provided on the surface of the side wing plate 201. Guard edges are provided on both sides of the opening of the vertical groove 205, so that the roller 204 can only slide in the vertical groove 205.

[0036] That is, when the side wing plate 201 needs to be driven to open, the driving end of the automatic telescopic rod 203 contracts inward, and at this time, the roller 204 at the front end of the automatic telescopic rod 203 moves along the vertical groove 205 toward the direction close to the hull 1. Since the ribs are provided on both sides of the groove opening, the roller 204 at the front end of the automatic telescopic rod 203 can only move in the groove and cannot escape from the groove. The roller 204 at the front end of the automatic telescopic rod 203 will pull the side wing plate 201 to move upward, that is, the side wing plate 201 is in an open state, and the opening angle of the side wing plate 201 can be controlled by controlling the telescopic distance of the telescopic rod.

[0037] When it is necessary to drive the side wing plate 201 to retract, the driving end of the automatic telescopic rod 203 extends forward, and the roller 204 at the front end of the automatic telescopic rod 203 moves along the vertical groove 205 away from the hull 1. Since there are ribs on both sides of the groove opening, the roller 204 at the front end of the automatic telescopic rod 203 can only move in the groove and cannot escape from the groove. The roller 204 at the front end of the automatic telescopic rod 203 will push the side wing plate 201 to move toward the bottom of the hull 1, so that the side wing plate 201 is in a retracted state and conforms to the bottom of the hull 1.

[0038] In this structure, the opening angle of the side wing plate 201 can be precisely controlled simply by controlling the extension distance of the driving end of the telescopic rod, and the control mechanism has a compact structure, a simple control method, and high control accuracy.

[0039] In this embodiment, the thickness of the side wing plate 201 close to the hull 1 is greater than the thickness of the other side.

[0040] Specifically, this arrangement can achieve a drag reduction effect. It is designed based on aerodynamic principles. The design principles are guided by the instruction manual and will not be repeated here.

[0041] In this embodiment, the cavitation system 3 includes a pressure stabilizing and flow equalizing chamber 301, and the power component is a fuel engine 302 arranged in the hull 1 for providing power to the hull 1. The air outlet of the fuel engine 302 is connected to the inlet of the pressure stabilizing and flow equalizing chamber 301 through an air supply pipe 303. Jet pipes 304 are respectively arranged on both sides of the hull 1, and a cavity is arranged inside the jet pipe 304. The jet pipe 304 is provided with a plurality of jet holes 305 on the side facing the outside of the hull 1, and the plurality of jet holes 305 are connected to the cavity. The jet pipe 304 is provided with an air inlet on the side facing the outside of the hull 1, and the air inlet is connected to the air outlet of the pressure stabilizing and flow equalizing chamber 301.

[0042] It needs to be explained that the pressure stabilizing and flow equalizing chamber 301 is an existing structure, and its function is to achieve the compression stability of the gas so that the released gas is high-pressure gas.

[0043] Specifically, when performing diving operations and needing to increase the navigation speed, the cavitation system 3 is turned on. During navigation, the fuel engine 302 provides the hull 1 with power for navigation. During the starting process of the fuel engine 302, the fuel engine 302 will generate gas, which is sent into the pressure stabilizing and flow equalizing chamber 301 through the air supply pipe 303. The pressure stabilizing and flow equalizing chamber 301 compresses and stabilizes the gas to form high-pressure gas, which is sent into the jet pipe 304 and ejected from the nozzle in the jet pipe 304, thereby forming an airflow layer on both sides of the hull 1, thereby reducing the resistance on both sides of the hull 1, so that the hull 1 can travel at the maximum navigation speed.

[0044] In this embodiment, the gas provided by the power structure, in combination with the setting of the pressure-stabilizing and equalizing flow chamber 301, the jet pipe 304 and the jet port, can realize the production of bubbles, thereby reducing the resistance of the hull 1 and the sailing speed of the water chestnut cake hull 1. At the same time, in this scheme, there is no need to set up a gas generating mechanism separately, and only the gas generated by its own gas power mechanism can be used. Therefore, the cavitation system 3 of this structure can be simple and practical.

[0045] It should be explained that when the hull 1 is in a floating state and the cavitation system 3 is not needed, when the fuel engine 302 is in a working state, the fuel engine 302 still produces gas, so the gas can be discharged through the ventilation system on the top of the hull 1.

[0046] In this embodiment, a blocking plate is provided on one side of the plurality of air jet holes 305, and a blocking plate driving structure is further included for driving the blocking plate to cover the air jet holes 305;

[0047] When the size of the air jet hole 305 needs to be adjusted, the blocking plate driving structure drives the blocking plate to move to completely or partially block the air jet hole 305 .

[0048] Specifically, when diving, the maximum sailing speed of the ship can be adjusted by adjusting the size of the jet hole 305. Specifically, when adjusting, the blocking plate driving mechanism drives the blocking plate to move, and the jet hole 305 is completely or partially blocked, so as to adjust the amount of bubbles generated, and then adjust the resistance of the hull, so as to achieve the adjustment of the speed. At the same time, when it is not necessary to generate bubbles, the jet hole 305 can be completely blocked.

[0049] In this structure, the size of the jet hole 305 can be adjusted through the design of the blocking plate, thereby adjusting the hull resistance.

[0050] In this embodiment, the hull 1 is provided with a wave detection mechanism for detecting the size of the waves, and also includes a control mechanism, which is respectively connected to the wave detection mechanism and the side wing plate driving mechanism 202 by signals;

[0051] The control mechanism is used to obtain the required opening angle of the wing structure 2 according to the size of the waves detected by the wave detection mechanism, and drive the wing structure 2 to open to the required angle through the wing plate driving mechanism 202.

[0052] Specifically, the wave detection mechanism described above is an existing device, which includes a visual sensor and a laser sensor. The size of the waves can be judged through the fusion detection of the visual sensor and the laser sensor, and then the angle at which the wing needs to be opened is obtained, and the side wing plate driving mechanism 202 drives the side wing plate 201 to adjust the angle.

[0053] The above structure can adjust the angle of the side wing plate 201 in real time, so as to resist the size of the wave through the different opening angles of the side wing plate 201, thereby ensuring the stability of the hull 1.

[0054] In this embodiment, a gyroscope installed in the hull 1 for detecting the tilt angle of the hull is also included. The gyroscope is connected to a control mechanism. The control mechanism is used to enable the side wing plate driving mechanism 202 to drive the side wing structure 2 to open to a desired angle according to the tilt angle of the hull 1 detected by the gyroscope.

[0055] Specifically, in this structure, the tilt angle of the hull 1 can be detected by setting a gyroscope, and then the opening angle of the side wing plate 201 can be adjusted in real time through the side wing plate driving mechanism 202, thereby increasing the self-restoring force of the hull, thereby maintaining the relative stability of the hull.

[0056] The present invention also discloses a navigation method of a hydrofoil cavitation ship, including the hydrofoil cavitation ship described above, specifically comprising:

[0057] When it is necessary to sail at the maximum speed on the water surface, the side wing plate 201 is controlled to be in a retracted state, and the side wing plate 201 is conformed to the hull;

[0058] When it is necessary to sail at the maximum speed under the water surface, the opening angle of the side wing plate 201 is controlled according to the waves and the tilt angle of the hull 1 to adjust the stability of the hull 1, and the cavitation system 3 discharges cavitation at the same time.

[0059] In this structure, the hydrofoil structure is designed to be conformal with the bottom surface of the hull 1, so that the hull 1 can sail at the maximum speed when on the water surface. At the same time, the cavitation system 3 is designed in this structure, so that the hull 1 can sail at the maximum speed when it is in a submerged state.

[0060] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
