Description

Technical Field

[0001] This utility model relates to the field of buoy deployment technology, specifically a buoy protection and displacement detection structure. Background Technology

[0002] The buoy deployment pod is powered by high-pressure gas to launch the buoy to a designated sea area. The high-pressure gas rushes into the buoy tube and causes the buoy to break the shear pin on the buoy cover. The buoy then continues to be launched out of the tube under the action of high-pressure gas. Because when a buoy is launched from the buoy tube using high-pressure gas, there may be cases where the buoy fails to launch successfully (the shear pin below the buoy has broken, but the buoy has not been successfully launched from the buoy tube). Currently, when a buoy is launched, if it fails to launch successfully, it is impossible to determine the buoy's displacement, resulting in some areas lacking buoys, which in turn leads to poor accuracy in buoy deployment. Meanwhile, if the buoy fails to launch successfully, it may accidentally slip off during the landing of the aircraft, resulting in poor safety of the buoy deployment. Furthermore, if the buoy fails to leave its position after launch, it may also slip off its intended deployment location during subsequent operations, affecting the accuracy of data collection. Utility Model Content

[0003] To address the above problems, this utility model provides a buoy protection and displacement detection structure, which solves the aforementioned issues.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a buoy protection and displacement detection structure, including a buoy mechanism, the buoy mechanism including a plurality of guide tubes and a buoy tube connected to one side of the guide tubes, a lower support frame connected to the outside of the guide tubes, a bottom cover baffle connected to the outside of the guide tubes, and the bottom cover baffle being disposed on one side of the lower support frame; Two infrared sensing mechanisms are connected to one side of the lower support frame, a through hole is opened on one side of the bottom cover baffle, a support base is connected to one side of the lower support frame, a servo motor is connected to one side of the support base, and a servo motor disk is connected to the output end of the servo motor. The servo disk is connected to a connecting frame, and two connecting rods are connected to the connecting frame. One end of each of the two connecting rods is connected to a protective stop bar. Guide openings are respectively opened on both sides of the support base, and the protective stop bars are set in the guide openings.

[0005] Preferably, the bottom cover baffle has an opening, and the protective baffle passes through the opening.

[0006] Preferably, a positioning ring is connected to one side of the buoy tube, and a buoy cover is provided in the positioning ring. Both the positioning ring and the buoy cover are provided with mounting grooves.

[0007] Preferably, a shear pin is installed on one side of the positioning ring and the buoy cover, and one end of the shear pin is installed in the mounting groove.

[0008] Preferably, the guide tube is externally connected to an upper support frame, and one end of the guide tube is connected to an air passage connector.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application uses a through hole on the bottom cover baffle to cooperate with an infrared sensing mechanism, which enables the infrared sensing mechanism to detect the launch displacement of the buoy. This solves the problem that if the buoy fails to launch successfully when it is launched, it is impossible to determine the displacement of the buoy, which helps to improve the accuracy of buoy deployment. 2. This application uses a servo motor to rotate and extend a protective stop bar through a slot on the bottom cover baffle. When the infrared sensor detects that the buoy launch has not left its position, it controls the protective stop bar to extend below the buoy launch trajectory to protect the buoy. This solves the problem that the buoy may accidentally slip off during subsequent operations when it fails to leave its position after launch, thus improving the safety of buoy deployment.

[0012] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0013] Please see Figures 1 to 5A buoy protection and displacement detection structure includes a buoy mechanism 1, which is installed on an aircraft. After the aircraft drives the buoy mechanism 1 to a designated position, it deploys the buoy. The buoy mechanism 1 includes several sets of guide tubes 2. This utility model only shows and describes a part of it, which does not affect the integrity of the technical solution. It should be noted that, because there are several sets of guide tubes 2, the normal guide tube 2 is equipped with a lower support frame 6 to install and fix the relevant components. The last set of guide tubes 2 is equipped with a bracket on one side. The infrared sensing mechanism 7, servo motor 10 and other components are installed on the bracket to detect and protect the launch of the last set of buoys. Except for the difference in appearance between the bracket and the other lower support frames 6, they are functionally the same, and the functions of the other components are also the same. Therefore, they will not be described or shown in detail. The buoy mechanism 1 includes several guide tubes 2 and a buoy tube 3 connected to one side of the guide tube 2. The guide tube 2 is connected to the lower support frame 6 on the outside, and the guide tube 2 is connected to the bottom cover baffle 5 on the outside. The bottom cover baffle 5 is located on one side of the lower support frame 6. Two infrared sensing mechanisms 7 are connected to one side of the lower support frame 6. A through hole 8 is opened on one side of the bottom cover baffle 5. The infrared sensing mechanism 7 corresponds to the through hole 8, so that the infrared sensing mechanism 7 can detect the buoy's displacement normally. Specifically, the infrared sensing mechanism 7 is a reflective infrared sensor. It will continuously emit infrared light to the empty area on the buoy deployment line. Since there is no object in the area, the emitted infrared light will directly penetrate or scatter, and the receiving end will hardly receive the reflected light. At this time, it is the default state of no object. When the buoy is deployed, as it passes through the detection area of ​​the infrared sensor mechanism 7, the buoy's outer shell reflects infrared light back to the sensor's receiver, causing the intensity of the reflected signal captured by the receiver to suddenly increase, far exceeding the previous intensity without a target. This drastic change in signal will be recognized by the circuit inside the sensor and determined to be a normal departure of the buoy. If the infrared detection mechanism 7 does not detect any buoy passing through the detection area after the buoy is launched, it is determined that the buoy launch has not left the position. A support base 9 is connected to one side of the lower support frame 6, a servo motor 10 is connected to one side of the support base 9, and a servo motor disk 11 is connected to the output end of the servo motor 10. A connecting frame 12 is connected to the servo disk 11, and two connecting rods 13 are connected to the connecting frame 12. One end of each connecting rod 13 is connected to a protective stop bar 14. Guide ports 15 are opened on both sides of the support base 9. The protective stop bar 14 is set in the guide port 15. When the buoy is launched, if the infrared detection mechanism 7 does not detect that the buoy has passed through the detection area, it is determined that the buoy launch has not left the position. At this time, the servo 10 will drive the servo disk 11 to rotate, so that the servo disk 11 drives the two connecting rods 13 to rotate to an angle that is level with the protective stop bar 14 through the connecting frame 12, thereby causing one end of the connecting rod 13 to push the protective stop bar 14 to move and extend in the guide port 15. It is important to note that the protective stop bar 14 is limited and guided by the guide port 15 so that the connecting rod 13 can push the protective stop bar 14 to extend normally. In addition, when the protective stop bar 14 extends, it will pass through the insertion port 16 on the bottom cover baffle 5 and reach one side of the buoy cover 4. At this time, the protective barrier 14 will limit and fix the buoy cover 4, which solves the problem that the buoy launch may not leave the position properly and may accidentally slip down later. This means that the buoy may not only deviate from the preset deployment position, affecting the accuracy of data collection, but may also accidentally slip down when the aircraft lands, resulting in poor safety of buoy deployment.

[0014] The bottom cover baffle 5 has an opening 16, and the protective baffle 14 passes through the opening 16.

[0015] A positioning ring 17 is connected to one side of the buoy tube 3. A buoy cover 4 is provided in the positioning ring 17. Both the positioning ring 17 and the buoy cover 4 are provided with mounting grooves 18.

[0016] A shear pin 19 is installed on one side of the positioning ring 17 and the buoy cover 4. One end of the shear pin 19 is installed in the mounting groove 18. The shear pin 19 is installed in the mounting groove 18 of the positioning ring 17 and passes through the mounting groove 18 of the buoy cover 4. When the buoy is not deployed, the shear pin 19 limits and fixes the buoy cover 4, thereby fixing the buoy. When the buoy is deployed, the high-pressure gas rushes into the guide tube 2 and the buoy tube 3, which will drive the buoy to break the shear pin 19 on the buoy cover 4. The buoy continues to be launched out of the buoy tube 3 under the action of high-pressure gas.

[0017] The guide tube 2 is externally connected to an upper support frame 20. One end of the guide tube 2 is connected to a gas connection connector 21, which is connected to a high-pressure gas cylinder. The high-pressure gas cylinder supplies gas through a gas pipe to the gas connection connector 21 and then into the guide tube 2 and the buoy tube 3 to deploy the buoy.

[0018] When using this utility model: First, the buoy mechanism 1 is installed on the aircraft. After the aircraft drives the buoy mechanism 1 to the designated position, it deploys the buoy. The air connection 21 is connected to the high-pressure gas cylinder. The high-pressure gas cylinder supplies gas through the air pipe to the air connection 21 and then enters the guide tube 2 and the buoy tube 3 to deploy the buoy. Secondly, the shear pin 19 is installed in the mounting groove 18 of the positioning ring 17 and passes through the mounting groove 18 of the buoy cover 4. When the buoy is not deployed, the shear pin 19 limits and fixes the buoy cover 4, thereby fixing the buoy. When the buoy is deployed, the high-pressure gas rushes into the guide tube 2 and the buoy tube 3, which will drive the buoy to break the shear pin 19 on the buoy cover 4. Then the buoy continues to be launched out of the buoy tube 3 under the action of high-pressure gas. Then, when the buoy is deployed, as the buoy passes through the detection area of ​​the infrared sensing mechanism 7, the buoy's outer shell reflects infrared light back to the sensor's receiver, causing the intensity of the reflected signal captured by the receiver to suddenly increase, far exceeding the previous intensity without a target. This drastic change in signal will be recognized by the circuit inside the sensor and determined to be a normal departure of the buoy after launch; if the infrared detection mechanism 7 does not detect any buoy passing through the detection area after the buoy is launched, it is determined to be a failure to leave the launch position. Finally, after the buoy is launched, if the infrared detection mechanism 7 does not detect any buoy passing through the detection area, it is determined that the buoy launch has not left its position. At this time, the servo motor 10 will drive the servo motor disk 11 to rotate, so that the servo motor disk 11 drives the two connecting rods 13 to rotate to an angle level with the protective barrier 14 through the connecting frame 12. This causes one end of the connecting rod 13 to push the protective barrier 14 to move and extend in the guide port 15. At this time, the protective barrier 14 will limit and fix the buoy cover 4, which solves the problem that the buoy launch has not left its position properly and may subsequently slip off unexpectedly. This means that the buoy that does not leave its position properly may not only deviate from the preset deployment position, affecting the accuracy of data collection, but may also slip off unexpectedly when the aircraft lands, resulting in poor safety of buoy deployment.
