Description
Technical Field
[0001] The utility model belongs to the technical field of ocean detection equipment, and in particular relates to a hidden folding and spreading wing mechanism for airdropping an underwater glider. Background Art
[0002] Underwater gliders are underwater unmanned submersibles used for ocean observation and research. Traditional underwater gliders need to rely on mother ships to transport them to the designated operating area, and then they are deployed manually or by other shipborne equipment. However, there are some problems with this method. First, it takes a certain amount of time to rely on mother ships to transport them to the operating area, especially for sea areas far away from land, the time cost is high. Secondly, the mother ship is greatly affected by the sea conditions, and it may not even be deployed when the sea conditions are poor, resulting in mission delays or even failures. In order to solve these problems, people began to explore the use of fixed-wing aircraft or drones to deploy underwater gliders. Compared with the traditional mother ship deployment method, the use of aircraft or drones to deploy underwater gliders has the following advantages: fast response, strong independence, high flexibility and cost-effectiveness. First, fixed-wing aircraft or drones can quickly fly to the designated operating area, greatly shortening the deployment time and improving the response speed. Secondly, aircraft or drones can independently complete the deployment task, without being restricted by the mother ship, and can complete the deployment task in poor sea conditions. In addition, the use of aircraft or drones to deploy underwater gliders allows for flexible selection of operating areas, no longer restricted by the mother ship's route, and allows for more accurate selection of the best observation points. Finally, although the use of aircraft or drones to deploy underwater gliders may increase costs to a certain extent, considering the time saved and the improved operating efficiency, it is a more economical and efficient option overall. Therefore, the use of fixed-wing aircraft or drones to deploy underwater gliders is a more efficient, flexible and economical way of ocean observation and research, which will provide more convenient technical support for marine scientific research and marine resource development.
[0003] Existing underwater gliders face the problem of large folded wings during airdrop, which can lead to a series of negative effects and problems. First, the large folded wings mean that the glider's folded wings need to withstand a large impact force during the process of entering the water from the air. Due to the large resistance of water, the folded wings are easily subjected to huge impact forces, thereby increasing the risk of damage to the folded wings when entering the water. Damage to the folded wings will not only affect the normal operation of the underwater glider, but may also cause the glider to fail to complete the mission, resulting in a waste of investment and resources.
[0004] Secondly, a larger wing span will also increase the instability during the airdrop process. In the air, the glider is greatly affected by the airflow, and a larger wing span will increase the possibility of the glider being disturbed by the airflow, reducing the accuracy and stability of the airdrop. Especially in severe weather conditions, such as strong winds or turbulent airflow areas, gliders with large wing spans are more easily affected, thereby increasing the risk during the airdrop process.
[0005] In addition, a large folded wing will also increase the impact on the structure of the glider itself during the airdrop process. A large folded wing requires a stronger support structure to ensure its stability, which will increase the weight and complexity of the glider and reduce its airdrop performance and adaptability. In addition, a large folded wing area will also increase the aerodynamic resistance of the glider during the airdrop process, affecting its airdrop distance and accuracy, and thus affecting the accuracy and efficiency of deployment.
[0006] Therefore, the problem of large folded wings of existing gliders not only increases the risk and instability of the glider during the airdrop process, but also affects the airdrop accuracy and efficiency of the glider, limiting its application in ocean observation and research.

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0034] In order to solve the risks and instability in the airdrop process caused by the large folding wings of the existing gliders, as well as the impact on the airdrop accuracy and efficiency of the gliders, the utility model provides a hidden folding wing mechanism for airdropping underwater gliders. The hidden folding wing mechanism design of the underwater glider simplifies the airdrop process, improves maneuverability and stability, and maintains good hydrodynamic performance and beautiful appearance. In order to further illustrate the structure of the utility model, the detailed description combined with the attached drawings is as follows:
[0035] See also Figure 1-Figure 10 A hidden folding wing mechanism for airdropping underwater gliders includes an axial linear movable module, a rear seat body, a folding wing 1, a hydrostatic pressure releaser 2, an energy storage spring 3 and an elastic pin locking component.
[0036] The axial linear movable module comprises an axially arranged sliding rod and a connecting rod slider 5 which is mounted on the sliding rod 4 to form a moving pair.
[0037] The rear seat body is provided with a sliding hole 6. Further, two sliding holes are symmetrically arranged on the rear seat body, and the two sliding holes are in an eight-shaped shape with a front width and a rear narrowness. The two sliding holes are respectively equipped with two folding wings symmetrically arranged by sliding columns.
[0038] The inner front part of the folding wing is hinged to the connecting rod slider through a pin shaft 7. The inner front part of the folding wing is equipped with a slide post 8, which is fitted in the slide hole. The slide post moves to the front and rear of the slide hole to respectively make the folding wing form an unfolded state and a folded state. The folding wing forms an unfolded state and a folded state based on the folding connecting rod structure principle of the mechanical principle.
[0039] The hydrostatic pressure releaser is installed on the rear seat body. The hydrostatic pressure releaser in the unpressurized state locks the folded wing position through the pin 9. The hydrostatic pressure releaser is controlled by the calibrated water pressure to release the locking relationship between the pin and the folded wing. The hydrostatic pressure releaser can use an existing finished component that senses water pressure and cuts off the pin after sensing the calibrated water pressure. When this finished component is used, the pin can use a flexible pin rope. In another way, the hydrostatic pressure releaser can be a combined unit composed of a water pressure sensor and an electromagnetic lock controlled by the water pressure sensor, and the pin is a retractable lock tongue of the electromagnetic lock.
[0040] The energy storage spring is installed on the axial linear movable module. When the folding wings are folded, the energy storage spring is squeezed by the connecting rod slider and exerts a forward elastic force on the connecting rod slider. Furthermore, the axial linear movable module includes two sliding rods arranged up and down, the connecting rod slider is arranged between the two sliding rods and combined with the two sliding rods through sliding holes, and the front mounting frame of the two sliding rods is fixed; it includes two axial linear movable modules arranged symmetrically on the left and right, and the two axial linear movable modules are respectively connected to the two folding wings arranged symmetrically on the left and right. The energy storage spring is sleeved on the sliding rod, and the two ends of the energy storage spring respectively press the connecting rod slider and the rear seat body. The "front" and "rear" mentioned above refer to the direction of the axial front end and the axial rear end of the underwater glider.
[0041] The elastic pin lock component is installed on the rear seat body. When the folding wings are folded, the elastic pin lock component forms a locking component that stops the folding wings through elasticity. Further, the elastic pin lock component is a folding wing pressing piece 10. The folding wing pressing piece is fixedly installed on the rear seat body. The outer end of the folding wing pressing piece forms an elastic force to press the upper wing surface of the folding wing. When the folding wings are opened, the folding wing pressing piece is pinned to the rear wing edge of the folding wing.
[0042] Furthermore, the rear seat body includes a rear seat upper plate 11, a rear seat lower plate 12 and a connecting rod. The rear seat upper plate and the rear seat lower plate are fixed to the rear end of the slide rod. A slot cavity for storing the folding wings in the folded state is formed between the rear seat upper plate and the rear seat lower plate. The connecting rod is installed on the rear seat upper plate and the rear seat lower plate. The connecting rod is provided with a keyway for combining with the folding wings in the folded state. The hydrostatic pressure releaser is installed on the connecting rod, and the pin of the hydrostatic pressure releaser passes through the keyway to lock the folding wings in the folded state. The rear seat upper plate and the rear seat lower plate are two plate components arranged up and down. The sliding holes are arranged on the rear seat upper plate and the rear seat lower plate to form a longitudinally penetrating double-layer sliding hole. The sliding column fixed on the folding wings is formed on the wing surfaces on both sides and is respectively combined with the upper and lower double-layer sliding holes.
[0043] The hidden folding wing mechanism for airdropping underwater gliders described in this embodiment cooperates with each other to automatically unfold the folding wings in water without wasting energy.
[0044] Specifically, two slide bars are passed through the reinforcement seat and fixed on the rear end cover of the underwater glider to make it stable and secure and keep the two slide bars parallel. Fig. 9 As shown in the arrow E direction, it opens smoothly from point B to point A without any lag. Assemble the other two slide bars in the same way as above.
[0045] Pass the two cylindrical holes on the horizontal end of the T-shaped connecting rod slider through the two sliding rods, such as Figure 6 The connecting rod slider forms an outward protrusion, and the horizontal end is close to the end cover of the underwater glider. Fig. 9 As shown in the figure, the connecting rod slider will slide along the two parallel sliding rods on the reinforcement seat from point B to point A in the direction of arrow E. Assemble the horizontal end of the other connecting rod slider in the same way. Install the energy storage spring on the sliding rod. When the hydrostatic pressure releaser is opened, Fig. 9 As shown in the figure, the folding wings will automatically and quickly unfold from direction B to direction A under the elastic force of the energy storage spring, and then assemble the remaining three springs. Fix the two slide bars in the upper part to the rear seat upper plate with screws, and ensure that the two slide bars are parallel after installation. Figure 4 As shown, the stepped hole at the end of the folding wing near the vertical end of the connecting rod slider is aligned with the stepped hole of the pressing plate 7 of the connecting rod slider, forming a hollow middle between the upper and lower clamping positions, and the pin is clamped in the stepped hole to achieve connection. Figure 8 As shown, the other end of the folding wing is installed in the sliding hole by a rotating shaft.
[0046] This is an embodiment, such as Figure 6 As shown in the figure, the rear seat upper plate and the rear seat lower plate are independent parts and the middle of the two parts is hollowed out to facilitate the assembly of the folding wings. Fig. 9 The folding wing slides from point C to point D in the hollow outer eight-shaped sliding hole formed by the outer eight-shaped curved grooves of the rear seat upper plate and the rear seat lower plate along the direction of arrow E and stops.
[0047] Install two spring sheets on the upper side of the rear seat upper plate to form a folding wing pressing sheet, such as Figure 7 When the folding wing slides from point C to point D along the direction of arrow E and stops, the spring sheet is used to clamp the folding wing so that the folding wing does not fold back to the initial closed state, allowing it to operate normally.
[0048] The connecting transition piece 13 is fixed on the rear seat upper plate and the rear seat lower plate. Because the two parts of the rear seat upper plate and the rear seat lower plate are completely separated and not connected, and the middle is completely connected, the transition piece also plays a role in stabilizing the entire folding wing connecting rod mechanism. The connecting rod includes a connecting rod upper cover 14 and a connecting rod lower cover 15, and the connecting rod upper cover and the connecting rod lower cover are installed on the connecting transition piece. A key groove is formed between the connecting rod upper cover 14 and the connecting rod lower cover 15 for the folding wing in the folded state to be embedded. The connecting rod upper cover 14 and the connecting rod lower cover 15 are provided with a through hole for the pin of the hydrostatic pressure releaser to pass through. The folding wing is provided with a locking hole. When the folding wing is in the folded state, the pin passes through the locking hole to achieve the position locking of the folding wing in the folded state. The upper end of the pin rope as the pin is connected to the hydrostatic pressure releaser, passes through the through hole, and the lower end is connected to the connecting rod lower cover.
[0049] Hydrostatic pressure release device Figure 8 Installed on the connecting rod cover.
[0050] like Fig.10 , further, a hidden folding wing mechanism for airdrop underwater gliders has an operation process in which when the state of the airdrop underwater glider before entering the water is as shown by the arrow E, the shaft slides to the point D in the hollow outer eight-shaped track formed by the outer eight-shaped bending sliding holes of the rear seat upper plate and the rear seat lower plate, and stops, driving the folding wing to fold, and the folding wing passes through the shaft connecting rod slider, and then the connecting rod slider extends the slide rod to slide horizontally from point A to point B. The connecting rod slider directly contacts the energy storage spring, and the spring is also compressed from point A to point B to store force. The folding wing compression sheet is above the folding wing. The hydrostatic pressure releaser locks the folding wing.
[0051] When the airdropped underwater glider reaches a certain depth after entering the water, the pressure increases accordingly. When the hydrostatic pressure releaser reaches the set pressure value, it starts to work, and the pin rope as the pin is cut off and the connection is released. Fig. 9 As shown in the figure, the folding wing stuck between the connecting rod upper cover and the connecting rod lower cover has no restraining force. Because the folding wing is connected to the connecting rod slider, the connecting rod slider is in direct contact with the energy storage spring and the energy storage spring is in a compressed state. The folding wing has no restraining force and finally releases the restriction of the compressed energy storage spring. The compressed energy storage spring unfolds and drives the connecting rod slider to slide horizontally from point B to point A along the slide rod, and stops when the rotating shaft on the folding wing slides to point D in the sliding hole, as shown in the figure. Fig. 9 As shown by the arrow E in the unfolding direction of the folding wing, after the folding wing is unfolded, the outer end of the folding wing pressing piece on the rear seat upper plate is pressed down and clamped on the inner side of the folding wing. The folding wing enters the water and automatically opens.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
