Description

Technical Field

[0001] The invention belongs to the technical field of underwater gliders, and in particular relates to an installation component and an installation method adapted to a hydrofoil of an underwater glider. Background Art

[0002] The hydrofoils of underwater gliders are similar to the wings of airplanes, which can provide lift during the movement of the glider and help the glider maintain a stable gliding state in the water. The horizontal main wing is the main component that affects the resistance and gliding performance of the underwater glider. Different main wing types will have different effects on the resistance and gliding performance of the underwater glider. Under the same wing shape, the underwater glider will be subject to different resistance and lift due to different sweep angles and elevation angles. The angle of the hydrofoil is adjusted to adapt to different water flow conditions and optimize the performance of the underwater glider.

[0003] However, the conventional device still has the following problems when used:

[0004] The patent application publication number is CN111152884B, which discloses a hydrofoil device and a hydrofoil boat. The hydrofoil device and the hydrofoil boat of this invention can reduce the resistance of the hydrofoil boat during navigation, increase the wing speed of the hydrofoil boat, and reduce the adverse interference between the wings when the hydrofoil boat is equipped with multiple wings.

[0005] When installing the hydrofoil on an existing underwater glider, the hydrofoil is usually fixed by screws or bolts. At this time, the hydrofoil is fixed on the underwater glider, so that the hydrofoil can only maintain a certain angle on the underwater glider and cannot change the angle of attack between the hydrofoil and the water flow, thereby affecting the lift and drag generated by the hydrofoil.

[0006] Therefore, we need installation components and installation methods that are compatible with the hydrofoils of underwater gliders to solve the problem that the angle of attack between the hydrofoils and the water flow cannot be changed after the existing hydrofoils are installed. The angle of the hydrofoil can be adjusted according to the size of the water flow after the hydrofoil is installed. Summary of the invention

[0036] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For example, see Figures 1 to 10The present invention provides a technical solution: comprising an underwater glider body 1, wherein the outer walls on both sides of the underwater glider body 1 are provided with cavities 4, the outer walls on both sides of the underwater glider body 1 are located on one side of the cavity 4 and are fixedly connected with waterproof grooves 3, the interior of the cavity 4 is movably plugged with a hydrofoil body 2, the interior of the cavity 4 is fixedly connected with a rotating shell 5, the interior of the rotating shell 5 is rotatably connected with a swing mechanism, the outer wall on one side of the swing mechanism is fixedly connected with a fixed shell 6, the outer wall on one side of the fixed shell 6 is fixedly connected with the outer wall on the other side of the rotating rod 54, the outer wall of the fixed shell 6 is slidably connected with the interior of the cavity 4, the interior of the fixed shell 6 is fixedly connected with baffles 66, the interior of the fixed shell 6 is fixedly connected with a triangular block 65, the interior of the fixed shell 6 is movable An insert block 63 is inserted, and the outer wall on one side of the insert block 63 is fixedly connected to the outer wall on one side of the hydrofoil body 2, and the outer wall on the other side of the insert block 63 is rotatably connected to an L-shaped rod 64, and the outer walls on the opposite sides of the two L-shaped rods 64 are in active contact with the outer wall of the triangular block 65, and the outer walls on the opposite sides of the two L-shaped rods 64 are in active contact with the outer wall of the baffle 66, and the outer walls on the opposite sides of the two baffles 66 are fixedly connected to elastic pads, and the outer wall on one side of the elastic pad is in active contact with the outer wall on one side of the L-shaped rod 64, and the outer wall on the other side of the fixed shell 6 is fixedly connected to a magnetic block 2 62, and the outer walls on one side of the hydrofoil body 2 are located on both sides of the insert block 63 and are fixedly connected to magnetic blocks 1 61, and the outer wall on one side of the magnetic block 1 61 is connected with the outer wall on one side of the magnetic block 2 62 with opposite poles attracting each other.

[0038] After the L-shaped rod 64 is fully inserted into the interior of the fixed shell 6 by the insertion block 63, the L-shaped rod 64 can be limited by the baffle 66, so that the L-shaped rod 64 is fixed inside the fixed shell 6, and the installation of the hydrofoil body 2 can be completed. The fixation of the hydrofoil body 2 by this operation reduces the operator's use of tools, and accordingly enables the hydrofoil body 2 to be quickly fixed to the underwater glider body 1, thereby reducing the time for installing the hydrofoil body 2, thereby improving the installation efficiency of the hydrofoil body 2 and making it simple and quick for the operator to operate.

[0039] Embodiment 2: On the basis of embodiment 1, a swing mechanism is used to drive the hydrofoil body 2 to automatically adjust the angle according to the water flow conditions, so that the underwater glider body 1 can maintain the best gliding posture and stability in different environments. The swing mechanism includes an operating shell 51, a rotating rod 54 and a moving rod 53. A track groove 52 is opened at the lower part of the rotating shell 5. One side of the rotating shell 5 is fixedly connected to the outer wall of one side of the operating shell 51. A reset spring 57 is fixedly connected to the outer wall of the front side of the fixed shell 6. The outer wall of one end of the reset spring 57 is fixedly connected to the inner wall of the cavity 4. The inside of the operating shell 51 is fixedly connected to the support rod. A circular hole connected to the outer walls on both sides is opened at one end of the top of the rotating rod 54. The inside of the circular hole is rotatably connected to the outer wall of the support rod. One side of the rotating rod 54 is an arc angle. The outer wall of the bottom of the rotating rod 54 is fixedly connected to the moving rod 53. The outer wall of the moving rod 53 is slidably connected to the outer wall of the track groove 52, and the outer wall of the rotating rod 54 is rotatably connected to the inside of the operating shell 51.

[0040] By rotating the rotating rod 54 inside the cavity 4, the angle of attack between the hydrofoil body 2 and the water flow can be changed, so that the hydrofoil body 2 can automatically adjust the angle according to the water flow conditions, so that the underwater glider body 1 can maintain the best gliding posture and stability in different environments. At the same time, by adjusting the angle of the hydrofoil body 2, the lift-to-drag ratio of the underwater glider body 1 can be optimized, and its energy utilization efficiency and endurance can be improved. In addition, the reset spring 57 has a certain buffering effect, which can improve the stability of the movement of the underwater glider body 1.

[0041] Embodiment 3, on the basis of embodiment 2, telescopic waterproof plates 32 are fixedly connected to both sides of the inside of the two waterproof grooves 3, the outer walls at one end of the two telescopic waterproof plates 32 are fixedly connected to the mounting plates 31, and the inside of the waterproof groove 3 is located in the middle of the telescopic waterproof plates 32 and is fixedly connected to a push spring 33, the outer wall at one end of the push spring 33 is fixedly connected to the outer wall on one side of the mounting plate 31, and the outer walls on the opposite side of the two mounting plates 31 are in active contact with the outer walls on both sides of the hydrofoil body 2.

[0042] Through the pushing force of the pushing spring 33, the mounting plate 31 is pushed to move along with the movement of the hydrofoil body 2, and then through the movement of the mounting plate 31, the pushing spring 33 can be driven to move, so that the pushing spring 33 moves inside the waterproof groove 3, and then through the cooperation of the mounting plate 31 and the pushing spring 33, water is prevented from entering the interior of the cavity 4, so that the internal structure of the cavity 4 is immersed in water, which correspondingly prevents water from entering the interior of the cavity 4 and increases the service life of the internal structure of the cavity 4.

[0043] Embodiment 4, based on embodiment 2, the outer walls on both sides of the rotating rod 54 are fixedly connected with multiple elastic semicircles 55, the inner walls on both sides of the upper and lower sides inside the operating shell 51 are fixedly connected with multiple limit rods 56, and the outer walls of the multiple elastic semicircles 55 are in active contact with the outer walls of the limit rods 56.

[0044] By means of the elastic semicircle 55 provided on the rotating rod 54 and the limiting rod 56 provided on the operating shell 51, and by means of the cooperation between the elastic semicircle 55 and the limiting rod 56, when the rotating rod 54 rotates inside the operating shell 51, the resistance to the rotating rod 54 is increased, thereby preventing the rotating rod 54 from driving the hydrofoil body 2 to move due to a slight change in the water flow. Accordingly, the existence of the resistance prevents sudden changes in the angle of the hydrofoil body 2, thereby improving the stability of the hydrofoil body 2 during the adjustment process to adapt to different water flow conditions.

[0045] Example 5. Constant-depth navigation resistance experiment. After the above settings, the drag performance calculation of underwater gliders with different airfoils and different sweep angles at an incoming flow velocity of 1 m / s was solved with a time step of 0.05 s and a maximum physical stop time of 10 s. A total of 9 simulation experiments were performed to obtain the magnitude and direction of the force and torque on the underwater glider. The total resistance data of each airfoil is summarized as follows: Fig.11 , Fig.12 , Fig.13 .The manta ray's wing has only one sweep angle.

[0046] Fig.11 is the drag data diagram of each sweep angle of the flat airfoil, Fig.12 This is the drag data diagram of the NACA airfoil at various sweep angles. Fig.13 This is a comparison chart of drag data for all configurations of flat airfoils, NACA airfoils, and manta ray airfoils. From the data, we can know that:

[0047] The underwater glider body 1 is composed of Fig.11 It can be seen that the drag of the flat airfoil decreases as the sweep angle decreases. From 12, it can be seen that the drag of the NACA airfoil decreases as the sweep angle decreases. The change patterns of the drag of the two models with the sweep angle are similar.

[0048] For the flat airfoil of the hydrofoil body 2, the slope of the curve is small in the range of 90° to 75°, the slope of the curve becomes larger in the range of 75° to 60°, and the slope of the curve is the largest in the range of 60° to 45°.

[0049] For the NACA airfoil, the slope of the drag curve is relatively uniform in the range of 90° to 45°. The drag of the NACA airfoil is smaller than that of the flat airfoil, and the drag of the NACA airfoil decreases with the sweep angle, and the trend of drag reduction is relatively stable. The drag of the manta ray airfoil is between the two.

[0050] The working principle and use process of the present invention are as follows: when in use, first, the operator manually moves the mounting plate 31 toward the two ends of the waterproof groove 3, and then the movement of the mounting plate 31 can make the cavity 4 on the underwater glider body 1 leak out, and then the hydrofoil body 2 drives the plug 63 to be inserted into the interior of the fixed shell 6, and then the movement of the plug 63 can make the L-shaped rod 64 move accordingly, and then through the triangular block 65 provided inside the fixed shell 6, when the L-shaped rod 64 enters the interior of the fixed shell 6, the triangular block 65 can be used to make the L-shaped rod 64 move along the edge of the triangular block 65, Thereby, the L-shaped rod 64 is rotated on the plug block 63. When the plug block 63 drives the L-shaped rod 64 to be completely inserted into the interior of the fixed shell 6, the L-shaped rod 64 can be limited by the action of the baffle plate 66, so that the L-shaped rod 64 is fixed inside the fixed shell 6, and the installation of the hydrofoil body 2 can be completed. The fixation of the hydrofoil body 2 by this operation reduces the operator's use of tools, and accordingly enables the hydrofoil body 2 to be quickly fixed to the underwater glider body 1, thereby reducing the time for installing the hydrofoil body 2, thereby improving the installation efficiency of the hydrofoil body 2 and making it simple and quick for the operator to operate.

[0051] After the insert block 63 is completely inserted into the interior of the fixed shell 6, the magnetic block 1 61 and the magnetic block 2 62 can be fitted together, and then the attraction between the opposite poles of the magnetic block 1 61 and the magnetic block 2 62 further increases the fixation of the hydrofoil body 2 and the fixed shell 6, thereby improving the stability of the fixation of the hydrofoil body 2.

[0052] It should be noted that: by using the elastic pad provided on the baffle 66 , when the insert block 63 is taken out from the interior of the fixed shell 6 , the two L-shaped rods 64 move together, making it easy to take the L-shaped rods 64 out of the interior of the fixed shell 6 .

[0053] When the underwater glider body 1 moves in the water, the water flow will generate forces on the hydrofoil body 2, and these forces are transmitted to the return spring 57 through the fixed shell 6, causing it to deform. Then, through the deformation and shortening of the return spring 57, the fixed shell 6 will drive the rotating rod 54 to rotate on the support rod inside the operating shell 51. The rotating rod 54 rotates inside the cavity 4, and the angle of attack between the hydrofoil body 2 and the water flow can be changed, so that the hydrofoil body 2 can automatically adjust the angle according to the water flow conditions, so that the underwater glider body 1 can maintain the best gliding posture and stability in different environments. At the same time, by adjusting the angle of the hydrofoil body 2, the lift-to-drag ratio of the underwater glider body 1 can be optimized, and its energy utilization efficiency and endurance can be improved. In addition, the return spring 57 has a certain buffering effect, which can improve the stability of the movement of the underwater glider body 1.

[0054] It should be noted that when the resistance of the water flow is reduced, the restoring force of the reset spring 57 can push the fixed shell 6 to drive the hydrofoil body 2 to return to its original position. Then the length of the cavity 4 is only enough for the hydrofoil body 2 to move from ninety degrees to forty degrees, thereby limiting the rotation angle of the hydrofoil body 2 and preventing the hydrofoil body 2 from exceeding the safety range.

[0055] By means of the elastic semicircle 55 provided on the rotating rod 54 and the limiting rod 56 provided on the operating shell 51, when the rotating rod 54 rotates inside the operating shell 51, the resistance to the rotating rod 54 is increased, thereby preventing the rotating rod 54 from driving the hydrofoil body 2 to move due to a slight change in the water flow. Accordingly, the existence of resistance prevents sudden changes in the angle of the hydrofoil body 2, thereby improving the stability of the hydrofoil body 2 during adjustment to adapt to different water flow conditions.

[0056] When the hydrofoil body 2 moves with the water flow, the pushing force of the pushing spring 33 can push the mounting plate 31 to move with the movement of the hydrofoil body 2, and then the movement of the mounting plate 31 can drive the telescopic waterproof plate 32 to move, so that the pushing spring 33 moves inside the waterproof groove 3, and then the cooperation between the mounting plate 31 and the pushing spring 33 can prevent water from entering the interior of the cavity 4, so that the internal structure of the cavity 4 is immersed in water, which correspondingly prevents water from entering the interior of the cavity 4 and increases the service life of the internal structure of the cavity 4.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The installation method adapted to the underwater glider hydrofoil is realized based on the installation assembly adapted to the underwater glider hydrofoil according to any one of claims 1 to 2, and the installation method adapted to the underwater glider hydrofoil comprises the following steps: Step 1: First, the operator manually moves the mounting plate (31) toward the two ends of the waterproof groove (3), and then the movement of the mounting plate (31) causes the cavity (4) on the underwater glider body (1) to leak out, and then the hydrofoil body (2) drives the plug (63) to be inserted into the interior of the fixed shell (6); Step 2: When the underwater glider body (1) is launched into the water and moves, the water flow will generate a force on the hydrofoil body (2), and the force is transmitted to the return spring (57) through the fixed shell (6), causing it to deform. Then, the return spring (57) is deformed and shortened, so that the fixed shell (6) drives the rotating rod (54) to rotate on the support rod inside the operating shell (51), and then the rotating rod (54) rotates inside the cavity (4), thereby changing the angle of attack between the hydrofoil body (2) and the water flow; Step three: When the hydrofoil body (2) moves under the condition of water flow, the installation plate (31) is pushed to move along with the movement of the hydrofoil body (2) under the action of the pushing force of the pushing spring (33), thereby preventing water from entering the interior of the cavity (4).
