Description

Technical Field

[0001] This utility model relates to the field of aviation protection equipment technology, specifically to an engine exhaust nozzle heat flow deflector. Background Technology

[0002] The engine exhaust nozzle heat flow deflector is a key protective device installed on the flight deck of an aircraft carrier. It is specifically designed to block the high-temperature exhaust plumes of carrier-based aircraft during takeoff. Through a flow guiding structure and heat dissipation system, the heat flow is directed to the sides and top to prevent damage to deck facilities and personnel.

[0003] When carrier-based aircraft take off, protective plates are installed to protect the ship's deck and personnel. However, the size of conventional protective plates is usually fixed. The size of carrier-based aircraft parked on the ship varies, and the power required for takeoff varies, resulting in different exhaust plume heights, which reduces the effectiveness of protecting the ship's deck.

[0004] Therefore, we propose an engine exhaust nozzle heat flow deflector to address the problems mentioned above. Utility Model Content

A cooling component 8 is provided in the inner cavity of the groove 2 near the other side. Grooves 3 are provided on both sides of the inner cavity of the groove 2 near the top. A fixing groove is provided on the rear side of the inner cavity of the groove 2, and a servo motor A4 is fixedly installed on the rear side of the inner cavity of the fixing groove. A protective plate 6 is provided in the inner cavity of the groove 2. Movable shafts 5 are fixedly installed at the top of the front and rear sides of the protective plate 6. The front end of the front movable shaft 5 is rotatably connected to the front side of the inner cavity of the groove 2, and the rear end of the rear movable shaft 5 is fixedly connected to the power output shaft end of the servo motor A4. An adjustment component 7 is provided in the inner cavity of the protective plate 6. The adjustment assembly 7 includes a cavity 71 opened on the protective plate 6 and a servo motor B72 fixedly installed on one side of the cavity 71. A T-shaped threaded rod 73 is fixedly installed on the power output shaft end of the servo motor B72, and a threaded sleeve 74 is threadedly connected to the outer circumference of the T-shaped threaded rod 73. A connecting bracket 75 is fixedly installed on the other side of the threaded sleeve 74 near the top and bottom, and an extension plate 76 is fixedly installed on the other side of the connecting bracket 75.

[0019] Specifically, when protecting against exhaust plumes, after the protective plate 6 is rotated 90 degrees, with the cooperation of the adjustment component 7, the threaded sleeve 74, which is threaded to the outer periphery of the T-shaped threaded rod 73, can move upward under the rotation of the T-shaped threaded rod 73. The position of the extension plate 76 can be adjusted by the connecting bracket 75 fixed on the threaded sleeve 74, so that it can be used for carrier-based aircraft of different sizes and improve the application range of the device.

[0020] Limiting telescopic rods 761 are fixedly installed on one side of the extension plate 76 near the top and bottom, and one end of each limiting telescopic rod 761 is fixedly connected to the inner cavity of the cavity 71.

[0021] Specifically, by setting the limiting telescopic rod 761, the movement of the extension plate 76 can be limited, thereby improving its movement stability.

[0022] On the opposite side of the inner cavity of the groove 3, near the front and rear sides, a multi-stage hydraulic telescopic rod 31 is fixedly installed, and the ends of two adjacent multi-stage hydraulic telescopic rods 31 are fixedly installed with a horizontal plate 32, which are fitted together with each other.

[0023] Specifically, by setting up multi-stage hydraulic rods 31 to move the horizontal plate 32, the tank 2 can be blocked.

[0024] Both the extension plate 76 and the protective plate 6 are made of high-temperature resistant steel plates. Example

[0025] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 5 The cooling assembly 8 includes a drive motor 81 fixedly installed on the rear side of the inner cavity of the tank 2 and a reciprocating lead screw 82 fixedly installed on the power output shaft end of the drive motor 81. The front end of the reciprocating lead screw 82 is rotatably connected to the front side of the inner cavity of the tank 2. A lead screw nut 83 is movably sleeved on the outer periphery of the reciprocating lead screw 82 near the rear end. A cooling nozzle 84 is fixedly installed on the top of the lead screw nut 83. A connecting pipe 85 is fixedly installed on the other side of the cooling nozzle 84. The surfaces of the drive motor 81, the reciprocating lead screw 82, the lead screw nut 83, the cooling nozzle 84, and the connecting pipe 85 are all coated with a ceramic coating (Al2O3 / ZrO2).

[0026] Specifically, when it is necessary to cool the protective plate 6, with the cooperation of the cooling component 8, when the reciprocating screw 82 rotates, the screw nut 83, which moves around the outer periphery of the reciprocating screw 82, can reciprocate under the limitation of the limiting block 831 and the limiting rod 832. With the connection of the connecting pipe 85, water can be supplied to the cooling nozzle 84 (the water pump is not shown in the figure. The water inlet of the water pump is connected to the external water tank, and the connecting pipe 86 can be connected to the water pump). This can cool the protective plate 6 evenly, prevent other personnel from being burned, and improve the safety of the device.

[0027] A limiting block 831 is fixedly installed at the bottom of the lead screw nut 83, and the front side of the limiting block 831 moves through the limiting rod 832, and both the front and rear ends of the limiting rod 832 are fixedly connected to the inner cavity sidewall of the groove 2.

[0028] Specifically, by setting the limit block 831 and the limit rod 832, the movement of the lead screw nut 83 can be limited, thereby improving the stability of its movement.

[0029] It should be noted that all electrical devices in this application are electrically connected to an external controller and are connected to an external power source. All parts in this application have undergone high-temperature resistant processing.

[0030] Working Principle: In use, before the carrier-based aircraft starts, the multi-stage hydraulic telescopic rod 31 can be activated via an external controller, causing the two horizontal plates 32 to move to opposite sides, opening the slot 2. Then, the servo motor A4 is activated via the external controller, rotating the power output shaft of servo motor A4 and causing the adjacent movable shaft 5 fixed to the end of the servo motor A4 to rotate, thus rotating the protective plate 6 to 90 degrees. The height of the protective plate 6 can be adjusted according to the model of the carrier-based aircraft. Afterwards, the servo motor B72 is activated via the external controller, rotating the power output shaft of servo motor B72 and causing the T-shaped threaded rod 73 fixed to the end of the servo motor B72 to rotate. Through the threaded sleeve 74 threaded to the outer circumference of the T-shaped threaded rod 73 and the connection of the connecting frame 75, the extension plate 76 can be moved between the two adjacent limiting telescopic rods 761. The upward movement of the limit switch increases the protective height of the protective plate 6, improving the protective effect of the device. After protection is completed, the extension plate 76 can be retracted into the inner cavity of the cavity 71. Then, the protective plate 6 is restored to its initial state. Afterward, the external water pump (not shown in the diagram, the water pump inlet is connected to an external water tank, and the connecting pipe 86 can be connected to the water pump) can be started by the external controller. The drive motor 81 is started by the external controller. The rotation of the power output shaft of the drive motor 81 causes the reciprocating screw 82 fixed at the end of the power output shaft of the drive motor 81 to rotate. This causes the screw nut 83, which moves around the reciprocating screw 82, to reciprocate under the limit of the limit block 831 and the limit rod 832. With the connection of the connecting pipe 85, water can be supplied to the cooling nozzle 84, thereby uniformly cooling the protective plate 6, preventing other personnel from being burned, and improving the safety of the device.
