Description

Technical Field

[0001] This invention relates to a vortex generating device, and more particularly to a vortex generating device for promoting exhaust on an underwater moving platform. Background Technology

[0002] Submarine-launched vehicles typically have an internal gas storage chamber and exhaust ports on their shoulders. The gas pressure inside the gas storage chamber is comparable to the ambient pressure at the time of launch. During vertical motion, as the water depth decreases, the gas is passively expelled under the pressure difference between the inside and outside of the gas chamber, forming an air layer that surrounds the surface of the vehicle, thereby achieving the purpose of reducing load and drag. Although this exhaust method has a simple internal structure, because it relies solely on pressure difference to drive the gas out, the momentum of the gas at the exhaust port is relatively small. This makes it susceptible to erosion by the incoming flow, which can cause blockage of the exhaust port and interrupt the exhaust process, thus negating the purpose of reducing load and drag. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to propose a vortex generator for promoting exhaust in underwater motion platforms, thereby achieving exhaust control during the vertical movement of underwater vehicles and improving load reduction and drag reduction effects.

[0004] Technical Solution: This invention includes a support component, a movable component, and a protective component. The protective component includes a balloon protective cover and a balloon puncture needle. One end of the balloon protective cover is connected to the support component, and the other end is connected to the movable component. The movable component includes an inner connecting rod, an inflated balloon, an outer connecting rod, and an elastic connecting rod. The inflated balloon is placed inside the balloon protective cover. One end of the balloon protective cover is fixed with the inner connecting rod, and the other end is fixed with the outer connecting rod. The outer connecting rod is connected to the outer wall of the hull. Both ends of the elastic connecting rod are fixedly connected to the inside of the balloon protective cover. The expansion of the inflated balloon drives the elastic connecting rod to move, thereby pushing the outer connecting rod to extend outward. When the inflated balloon expands to contact the balloon puncture needle, the inflated balloon is punctured, the stretched elastic connecting rod retracts, and the outer connecting rod is pulled back inward to its initial state.

[0005] The outer end connecting rod is equipped with a limiting piece at the end that connects to the outer wall of the naval vessel. The limiting piece prevents the outer end connecting rod from extending too far outward, and at the same time, the limiting piece can effectively prevent gas from leaking from the outer end connecting rod.

[0006] At the initial moment of the movement of the navigator, the outermost end of the connecting rod is flush with the outer wall of the navigator. During the vertical movement of the navigator, the pressure decreases, causing the balloon to expand, thereby stretching the elastic connecting rod and pushing the outer connecting rod to extend outward. This causes the outer connecting rod to extend towards the outer wall of the navigator, forming a vortex generating device protruding from the outer wall of the navigator.

[0007] The gas pressure inside the inflating balloon is the same as the water pressure environment where the vehicle is located. As the vehicle moves vertically, the air chamber exhausts gas outward through the exhaust port, the pressure inside the air chamber decreases, and the inflating balloon expands.

[0008] The support assembly includes a support screw, with a connector sleeved on the outside of the support screw. The connector has multiple quick-connect fittings arranged in a circumferential array to facilitate connection of the inner end connecting rod.

[0009] The support screw is fixedly connected to the upper and lower ends of the air chamber of the aircraft.

[0010] The other end of the inner connecting rod is connected to a quick-connect fitting, and is connected to the connector through the quick-connect fitting.

[0011] The inflatable balloon is made of elastic rubber and filled with air or inert gas. The gas pressure inside the inflatable balloon is equivalent to the pressure of the water environment where the voyage is located.

[0012] The limiting piece is a rubber limiting piece, the position of which can be adjusted back and forth along the outer end connecting rod. The limiting piece prevents the outer end connecting rod from extending too far outward, and at the same time, the limiting piece can effectively prevent gas from leaking from the outer end connecting rod.

[0013] The vortex generator is installed above the exhaust port of the aircraft carrier, and the number of rods can be easily adjusted according to the number of exhaust ports of the aircraft carrier to meet the requirements of economy and timeliness.

[0014] Beneficial effects: This invention has the following advantages:

[0015] (1) The vortex generator of the present invention can induce gas discharge during the vertical motion of the submarine body, increase the gas discharge momentum, and even if it is subjected to the scouring effect of the incoming flow, the gas can be discharged normally at the normal angle of attack, thereby effectively achieving the purpose of reducing load and drag of the submarine-launched submarine body.

[0016] (2) The internal pressure of the inflating balloon of the device is consistent with the initial water depth pressure of the vehicle. As the vehicle moves vertically, the balloon expands as the pressure decreases, thereby driving the elastic connecting rod to extend outward without the need for additional power. After the inflating balloon is punctured, the elastic connecting rod rebounds to the normal position, thereby driving the outer connecting rod to retract and restore the surface of the vehicle to a smooth state without the need for additional power.

[0017] (3) The device is installed inside the air chamber of the underwater vehicle, without occupying extra space inside the vehicle. It is simple to manufacture, has a reliable structure, and low manufacturing cost. At the same time, the number of rods can be easily adjusted according to the number of exhaust holes of the vehicle, meeting the requirements of economy and timeliness. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the overall structure of the present invention. Figure 2 . Detailed Implementation

[0020] The invention will now be further described with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the underwater motion platform vortex generator for promoting exhaust is installed above the exhaust port of the vehicle body and includes a support assembly 1, a movable assembly 2, and a protective assembly 3. The support assembly 1 includes a support screw 4, a connector 5, and quick-connect fittings 6. The support screw 4 is fixedly connected to the upper and lower ends of the air chamber of the vehicle body. The connector 5 is connected to the support screw 4 by a thread and can be adjusted vertically. The connector 5 has a plurality of quick-connect fittings 6 arranged in a circumferential array and is installed inside the connector 5.

[0022] The protective component 3 includes a balloon protective cover 12 and a balloon puncture needle 13. One end of the balloon protective cover 12 is connected to the support component 1, and the other end is connected to the movable component 2. The movable component 2 includes an inner connecting rod 7, an inflated balloon 8, an outer connecting rod 9, a limiting piece 10, and an elastic connecting rod 11. The inflated balloon 8 is made of elastic rubber and can be filled with air or inert gas. The inflated balloon 8 is placed inside the balloon protective cover 12. After reaching the limiting point, the balloon is punctured as it continues to inflate, preventing the balloon from remaining in an inflated state. At the same time, the elastic connecting rod inside the movable component springs back, thus returning to its initial position. The balloon protective cover 12 consists of two shell structures, front and rear. An inner connecting rod 7 is fixed to one end, and an outer connecting rod 9 is fixed to the other end. The other end of the inner connecting rod 7 is connected to a quick-connect fitting 6, which in turn connects to a connector 5. The outer connecting rod 9 is connected to the outer wall of the navigator, and a limiting piece 10 is installed at the end connected to the outer wall to prevent the outer connecting rod 9 from extending too far outward. The limiting piece 10 also effectively prevents gas leakage from the outer connecting rod 9. The outermost end of the outer connecting rod 9 is flush with the outer wall surface at the initial moment of the navigator's movement. The limiting piece 10 is a rubber limiting piece, and its position can be adjusted back and forth along the outer connecting rod 9. An elastic connecting rod 11 is fixedly connected at both ends to the opposite sides of the two shell structures of the balloon protective cover 12. The expansion of the balloon 8 drives the elastic connecting rod 11 to move, thereby pushing the outer connecting rod 9 outward.

[0023] This arrangement allows the balloon to inflate due to reduced pressure during the vertical movement of the spacecraft. This inflates the elastic connecting rod, pushing the outer connecting rod outward. Consequently, the outer connecting rod extends towards the outer wall of the spacecraft, forming a vortex-generating device protruding from the outer wall. In the initial, uninflated state, the elastic connecting rod 11 is in its normal position, with the outer connecting rod flush with the outer wall of the spacecraft, which is smooth.

[0024] The balloon puncture needle 13 is fixedly installed inside the balloon protective cover 12. When the inflated balloon 8 expands to a certain extent, it contacts the balloon puncture needle 13 to puncture the inflated balloon 8, preventing the balloon from expanding indefinitely and squeezing the limiting plate 10. At this time, the stretched elastic connecting rod 11 retracts, driving the outer connecting rod 9 to retract inward and return to its initial state, ensuring the smoothness of the outer wall of the navigator.

[0025] During testing, the inner connecting rod 7 and the balloon protective cover 12 connected to the inner connecting rod 7 remained fixed. The internal gas pressure of the inflated balloon 8 was comparable to the pressure of the water environment at the same depth as the vehicle. As the vehicle moved vertically, the air chamber expelled gas through the exhaust port, reducing the internal pressure of the air chamber and causing the inflated balloon 8 to expand. This caused the elastic connecting rod 11 to move, pushing the connection between the balloon protective cover 12 and the outer connecting rod 9 outward to form a vortex generator protruding from the outer wall of the vehicle, thereby promoting the exhaust of gas from the air chamber.

[0026] The working principle of this invention is as follows:

[0027] During the vertical movement of the hull, as the external environmental pressure decreases, the volume of the inflating balloon within the protective assembly increases, pushing the movable component to extend towards the outer wall of the hull, forming a vortex-generating device protruding from the outer wall. This vortex-generating device creates a low-pressure zone on the back surface during the vertical movement of the hull, inducing accelerated gas discharge from the air chamber, increasing the gas discharge momentum, and preventing exhaust interruption, thereby improving load reduction and drag reduction. After the hull emerges from the water, as the pressure continues to decrease, the balloon, after inflating to a certain extent, is punctured by the balloon puncture needle, causing the elastic connecting rod to retract the outer connecting rod, ensuring a smooth outer wall of the hull and reducing air resistance. This invention achieves automatic extension and retraction functions through balloon inflation and elastic expansion, is simple to manufacture, and is safe and reliable. Compared to traditional exhaust devices, this invention improves exhaust capacity and effectively enhances load reduction and drag reduction.
