Description

Technical Field

[0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to a portable variable-sweep wing device for a hybrid power underwater vehicle. Background Art

[0002] For underwater vehicles that have both underwater glider functions and traditional propeller propulsion, in the underwater glider mode, the horizontal wings provide lift for the underwater vehicle to ensure that the vehicle can sail underwater with low power consumption. They are usually fixed on both sides of the vehicle and cannot be retracted. This will result in the horizontal wings increasing the navigation resistance of the vehicle and reducing the efficiency ratio of the vehicle in the traditional propeller propulsion mode; at the same time, the unfolded horizontal wings will generate large hydrodynamic disturbances when the vehicle is sailing, causing the vehicle to tilt significantly and even causing the vehicle to lose stability. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a portable variable-sweep wing device for a hybrid underwater vehicle, comprising a body guide, a connecting assembly for connecting to the underwater vehicle is provided at the bottom of the body guide, and horizontal wings are symmetrically provided on both sides of the body guide; a driving assembly is also provided on the body guide, and the driving assembly is used to drive the two horizontal wings to synchronously and symmetrically unfold or retract.

[0004] Further, the guide body includes a first guide body, a second guide body and a third guide body, one end of the first guide body is formed into a streamlined curved surface, and the other end of the first guide body is formed into a connecting surface; both ends of the second guide body are provided with structures matching the connecting surface, and the end of the second guide body is provided with a connection to the connecting surface; the length of the third guide body is equal to the length of the second guide body, the width of the third guide body is greater than the width of the second guide body, the outer wall of the third guide body is connected to the inner wall of the second guide body, and the two ends of the third guide body are formed into planes matching the second guide body; the bottom surfaces of the first guide body and the third guide body are formed into curved surfaces matching the underwater vehicle.

[0005] Furthermore, the inner walls of the first body guide, the second body guide and the third body guide are provided with a plurality of connection grooves perpendicular to the central axis of the body guide, and the connection assembly includes a plurality of fixing clamps matched with the connection grooves, and the fixing clamps are connected to the connection grooves by screws.

[0006] Furthermore, the top surface of the third body-conducting body is formed into a plane, the cross-sectional height of the third body-conducting body is smaller than the cross-sectional height of the second body-conducting body, and an accommodating cavity is formed between the outer wall of the third body-conducting body and the inner wall of the second body-conducting body;

[0007] A rotating bearing is fixedly provided between the second flow-guiding body and the third flow-guiding body, and the horizontal wing is inserted into the rotating bearing; the driving assembly comprises a lead screw motor axially arranged on the top surface of the third flow-guiding body, a traveling ring is sleeved on the screw of the lead screw motor, connecting rods are symmetrically hinged on both sides of the traveling ring, and the ends of the connecting rods are also hinged to the horizontal wings; the hinge shafts at both ends of the connecting rod and the rotating shaft bearings are arranged perpendicular to the top surface of the third flow-guiding body.

[0008] Furthermore, the length and height of the accommodating cavity are both greater than or equal to the length and height of the horizontal wing.

[0009] Furthermore, a limit baffle is provided on the top surface of the third flow guide body at a position corresponding to the end of the screw of the screw motor.

[0011] Furthermore, a vehicle penetration port cover is provided on the guide body at a position corresponding to the underwater vehicle body penetration watertight plug.

[0012] The beneficial effects of the present invention are:

[0013] The linearity of the hybrid underwater vehicle is optimized, taking into account the requirements for power and resistance in the two modes, and alleviating the contradiction between the two power modes on hydrodynamics and vehicle structure: in the glider power mode, the horizontal wings provide the vehicle with the lift required for gliding; in the propeller propulsion power mode, the horizontal wings are retracted into the guide body, eliminating the resistance brought by the horizontal wings and protecting the horizontal wings.

[0014] A limit-stop function is added to the transmission mechanism: In the power mode of the glider, the present application adopts a combination of a screw motor and a limit baffle to provide a torque for the horizontal wing to resist the navigation resistance, eliminating the situation where the screw motor continuously applies force, increasing the service life of the screw motor and reducing the energy consumption of the motor.

[0015] Increased system stability: In the propeller-driven power mode, the horizontal wings are not needed to provide lift. On the contrary, the deployed horizontal wings bring about a larger rolling disturbance at a relatively fast speed. The variable-sweep wing device retracts the horizontal wings to eliminate the rolling moment caused by the underwater environment.

[0016] The interface is highly versatile: it only needs to use the traditional hatch to realize the energy and control of the screw motor. It is universal with the watertight interface of traditional underwater equipment and can be plug-and-play. It only needs to provide the control command signal and energy supply to the screw motor.

[0017] Strong adaptability: The present application is fixed to the aircraft body by means of a fastening clamp. The fastening clamp is made of aluminum alloy material and is relatively thin, with a certain deformation function. The size of the fastening clamp can be adjusted according to the shape of different aircraft hulls, and can be connected to different hulls, greatly increasing the control performance of the device.

DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to explain the content of the present invention and are not used to limit the protection scope of the present invention.

[0032] Combination Figure 1 and Figure 2 The present invention proposes a hybrid underwater vehicle variable swept wing device, the components of which include: a first guide body 1, a second guide body 2, a third guide body 3, a horizontal wing 4, a fixing clamp 5, and a transmission mechanism responsible for the deployment and retraction of the horizontal wing. At the same time, other auxiliary components also include a first guide body fastening screw 6, a second guide body fastening screw 7, a clamp fastening screw 8, a vehicle penetration port cover 9, and a device fastening limit plate 16.

[0033] like Figure 2 As shown, the transmission mechanism mainly realizes the forward and backward movement of the traveling ring 12 by the rotation of the lead screw motor 10. The connecting rod 11 is connected to the traveling ring 12 through a transmission bearing 15, so that the connecting rod 11 can be driven to move during the movement of the traveling ring 12; the other end of the connecting rod 11 is connected to the horizontal wing 4 through a transmission bearing 15, and the other end of the horizontal wing is connected to the second guide body and the third guide body by a rotating bearing 14. The rotating bearing 14 serves as a rotating axis for the expansion and contraction of the horizontal wing 4, and the two ends of the bearing are respectively connected and fixed to the second guide body 2 and the third guide body 3. At the end of the screw of the lead screw motor 10, the limit baffle 13 is fixed to the third guide body 3. When the horizontal wing 4 is fully opened, the traveling ring 12 can be blocked by the limit baffle 13, thereby generating a supporting force for the horizontal wing 4 to offset the force generated by the lead screw motor 10 to resist the water flow resistance of the horizontal wing 4.

[0034] Conventional floating body materials are selected as the flow guide material, and the first flow guide 1, the second flow guide 2 and the third flow guide 3 together constitute the external main shape of the variable swept wing device: when the horizontal wing 4 is unfolded, that is, in the glider power mode, the horizontal wing can provide the aircraft with the lift required for gliding; when the horizontal wing 4 is retracted, that is, in the traditional propeller propulsion mode, the external main shape provides a good hydrodynamic shape for the horizontal wing 4 and related transmission mechanisms contained therein, reduces navigation resistance and improves stability.

[0035] like Figure 3 As shown, the first guide body 1 mainly optimizes the appearance design of the water-facing surface, and is fastened to the second guide body 2 by two fastening screws, and is fastened to the aircraft body by a fastening clamp 5. The first guide body 1 is fastened to the fastening clamp 5 by three screws.

[0036] Reference Figure 4 The second flow guide 2 is located behind the first flow guide 1, and has five screw holes in the middle of the back, which are used to fix the third flow guide 3 and the device fastening limit plate 16. The device fastening limit plate 16 can fix and position the second flow guide and the third flow guide. The front end of the back of the second flow guide 2 reserves a through hole for the charging interface and the screw motor control line. The second flow guide 2 is connected to two fastening clamps 5 one in front and one in back, and the two are also fastened by three screws.

[0037] like Figure 5 As shown, the third flow guide 3 is located below the second flow guide 2 and is surrounded by the second flow guide 2 from front to back, which can play a role in fastening and positioning. A receiving cavity is formed on both sides of the middle position of the two flow guides for placing the retracted horizontal wings 4. There is a matrix through hole with the same size as the device fastening limit plate 16 in the middle position of the back of the third flow guide 3, which is used for the device fastening limit plate 16 to pass through and fasten each other with the middle flow guide. The third flow guide 3 is connected to two fastening clamps 5, which are fastened by two screws with a diameter of 8 mm. The middle screw on the fastening clamp 5 is directly fastened to the device fastening limit plate 16 by one screw. This ensures that the second flow guide 2, the third flow guide 3 and the device fastening limit plate 16 are fastened and locked with each other.

[0038] Combination Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the fastening method between the variable sweep wing device and the underwater vehicle carried by it is realized by five fixing clamps 5 and twenty clamp fastening screws 8 distributed under the three guide bodies. Among them, from front to back, the upper parts of the first, second and fifth fixing clamps 5 are respectively fixed to the first guide body 1 and the second guide body 2, and are fixed to each other by three screws arranged at an opening angle of 30°. The third and fourth fixing clamps 5 are fastened and fixed to the third guide body 3 and the device fastening limit plate 16 at the same time by three holes arranged at an opening angle of 30°, and the other three holes of the device fastening limit plate 16 are fixed to the second guide body by screws.

[0039] like Fig.10As shown, the aircraft penetration port cover 9 is mainly responsible for the sealing function of the aircraft body penetration watertight plug. The diameter of the aircraft penetration port cover 9 is the same as the through hole of the second guide body 2, and the inside is hollowed out. The hollowed-out part is consistent with the shape of the underwater aircraft penetration watertight plug. The aircraft penetration port cover 9 is in direct contact with the aircraft hull. The end of the port cover that contacts the aircraft hull is arc-shaped, which is conducive to its fit with the aircraft. The O-ring on the aircraft penetration port cover 9 is used to directly seal with the metal surface of the aircraft. The aircraft penetration port cover 9 is fixed to the metal surface of the aircraft with four screws.

[0040] The deployment and retraction states of the horizontal wings are as follows: Fig.11 and Fig.12 It should be noted that the main body of the underwater vehicle is not the main content of the present invention and is represented by a simple rotating body instead.

[0041] In summary, the above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto. All equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification are within the scope covered by the patent of the present invention.
