Description

Technical Field

[0001] This utility model relates to the field of corner reflector technology, and in particular to a corner reflector slow-descent system and a corner reflector system. Background Technology

[0002] A corner reflector is an electromagnetic wave reflector made of metal sheets, manufactured in various specifications for different applications. Its core principle lies in its ability to reflect electromagnetic waves of various incident angles and frequencies in their original direction, thereby generating a very strong reflected signal. This characteristic makes corner reflectors widely used in many fields, such as creating strong targets in radar detection for warning purposes, and in safety areas such as maritime distress rescue and ship navigation, playing a particularly important role in foggy weather with poor visibility. Currently, radar corner reflectors are usually dropped into the sea or onto the land by gravity or external force to create artificial radar decoys, serving as radar jamming equipment.

[0003] However, in actual use, when an inflatable radar corner reflector falls into the sea, its radar reflection capability is affected by waves, causing it to fail to achieve the expected results. Similarly, during ground use, the radar transmission capability of an inflatable radar reflector can be blocked by hills or trees, thus affecting its performance. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0043] like Figure 1 As shown, the corner reflector descent system provided in this embodiment includes: a first connecting rope 11, a guide parachute pack 100, a guide parachute body 200, and a main parachute assembly 300; the guide parachute pack 100 is used to accommodate the guide parachute body 200; one end of the first connecting rope 11 is connected to the launch system 20, and the other end of the first connecting rope 11 is connected to the guide parachute pack 100. After the launch system 20 launches the descent system, when the descent system reaches the designated airspace, the first connecting rope 11 tauts, causing the guide parachute pack 100 to stop in the air. Due to inertia, the main parachute assembly 300 will still fly, pulling the guide parachute body 200 out of the guide parachute pack 100. The guide parachute body 200 unfolds, thereby enabling the main parachute assembly 300 to unfold under the drive of the guide parachute body 200, and thus causing the corner reflector system connected to the main parachute assembly 300 to slowly descend in the designated airspace.

[0044] In an optional embodiment, the corner reflector descent system further includes a break cord 400; one end of the break cord 400 is connected to the guide parachute pack 100, and the other end of the break cord 400 is connected to the guide parachute body 200, and the break cord 400 is configured to disconnect after the guide parachute body 200 is pulled out of the guide parachute pack 100, thereby separating the guide parachute pack 100 from the guide parachute body 200.

[0045] In an optional embodiment, the main umbrella assembly 300 includes a main umbrella pack 310 and a main umbrella body 320; the internal space of the main umbrella pack 310 is used to accommodate the main umbrella body 320, and the main umbrella pack 310 is connected to the guide umbrella body 200 by a second connecting rope 12, so that the guide umbrella body 200 can be pulled out from the main umbrella pack 310.

[0046] The main umbrella body 320 is used to connect with the corner reflector system. Specifically, the main umbrella body 320 is connected to the corner reflector system via the fourth connecting rope 14.

[0047] The main parachute body 320 is configured to be pulled out of the main parachute pack 310 under the resistance of the pilot parachute body 200 during wind-assisted deployment, so that the main parachute body 320 can be deployed under wind-assisted conditions. Specifically, after the pilot parachute body 200 is deployed, it is subject to wind resistance. Since the pilot parachute body 200 is connected to the main parachute pack 310, the main parachute pack 310 is subject to resistance. Due to inertia, the main parachute body 320 inside the main parachute pack 310 is dislodged from the main parachute pack 310, and then the main parachute body 320 is deployed under wind-assisted conditions.

[0048] In an optional embodiment, the corner reflector descent system further includes a third connecting rope 13; one end of the third connecting rope 13 is connected to the pilot parachute body 200, and the other end of the third connecting rope 13 is connected to the main parachute pack 310, thereby connecting the pilot parachute body 200 and the main parachute pack 310.

[0049] The specific working principle is as follows: The first connecting rope 11 is tightened, pulling out the guide parachute pack 100, so that the guide parachute body 200 is in an unrestrained state. At the same time, the rope 400 is pulled off, and the guide parachute pack 100 is completely separated from the guide parachute body 200 due to the deployment of the guide parachute body 200. After being resisted by the deployment of the guide parachute body 200, the third connecting rope 13 is tightened. Due to inertia, the main parachute pack 310, the main parachute body 320 and the corner reflector assembly 500 continue to move. The tightening of the third connecting rope 13 pulls out the main parachute pack 310, so that the main parachute body 320 is in an unrestrained state. The main parachute body 320 is fully deployed, and at this point, the descent system is fully deployed and has the ability to stay airborne.

[0050] The corner reflector descent system provided in this embodiment has the following advantages:

[0051] 1. Fully deployable and highly reliable: The system is accurately and fully deployed in the air through inertial separation and wind-assisted deployment of the main body of the parachute 200.

[0052] 2. Significantly increased loiter time: The guide parachute design enables the system to remain in the air for extended periods, thus extending its operational time.

[0053] 3. Reduce external environmental interference: Effectively avoid the impact of complex environmental factors such as ocean waves and ground obstacles, enhancing the system's adaptability and stability.

[0054] 4. Solve existing technical problems: It fundamentally alleviates the problem of poor performance of inflatable radar corner reflectors and provides a reliable solution for relevant application scenarios.

[0055] Based on the above embodiments, such as Figure 2 , Figure 3 As shown, the corner reflector system provided in this embodiment is connected to the corner reflector descent system provided in the above embodiment.

[0056] The corner reflector system includes a fourth connecting rope 14 and a corner reflector assembly 500; one end of the fourth connecting rope 14 is connected to the main umbrella assembly 300, and the other end of the fourth connecting rope 14 is connected to the corner reflector assembly 500, thereby connecting the main umbrella assembly 300 and the corner reflector assembly 500 through the fourth connecting rope 14.

[0057] In an optional embodiment, the corner reflector system includes a packaging bag 510 and an inflatable corner reflector 520; the packaging bag 510 is connected to a fourth connecting rope 14, and the interior of the packaging bag 510 is used to accommodate the inflatable corner reflector 520; the inflatable corner reflector 520 is configured to be inflated and deployed, and when the inflatable corner reflector 520 reaches a designated airspace, the inflatable corner reflector 520 is inflated and deployed.

[0058] In an optional embodiment, the corner reflector system further includes a sealing pin 530 for securing the inflatable corner reflector 520 within the packaging bag 510.

[0059] In addition, the sealing pin 530 is connected to the fourth connecting rope 14 via the first separating rope 550, so that the sealing pin 530 separates from the packaging bag 510 after the first separating rope 550 is taut. Specifically, when the fourth connecting rope 14 is tightened, the first separating rope 550 is then tightened, and the sealing pin 530 separates from the packaging bag 510, thereby releasing the restriction of the sealing pin 530 on the packaging bag 510, opening the packaging bag 510, and allowing the inflatable corner reflector 520 to inflate and unfold freely.

[0060] In an optional embodiment, the corner reflector system further includes an inflation component 540; the inflation component 540 is specifically configured as an inflation cylinder with a pull ring on it, and the inflation component 540 is disposed on the inflatable corner reflector 520. The inflation component 540 is used to inflate the inflatable corner reflector 520 to make the inflatable corner reflector 520 unfold.

[0061] In an optional embodiment, the corner reflector system further includes a second separation rope 560; one end of the second separation rope 560 is connected to the fourth connecting rope 14, and the other end of the second separation rope 560 is connected to the control part on the inflation member 540, so that when the second separation rope 560 is taut, the second separation rope 560 opens the inflation member 540. The control part is specifically a pull ring on the inflation cylinder. When the second separation rope 560 is taut, as the inflation cylinder moves with the inflated corner reflector 520 due to inertia, the second separation rope 560 separates the pull ring from the inflation cylinder, so that the inflation cylinder inflates and deploys the inflated corner reflector 520.

[0062] In an optional embodiment, the corner reflector system further includes a fifth connecting rope 15; one end of the fifth connecting rope 15 is connected to the fourth connecting rope 14, and the other end of the fifth connecting rope 15 is connected to the inflatable corner reflector 520, thereby connecting the fourth connecting rope 14 and the inflatable corner reflector 520; in addition, in order to ensure the separation priority, the rope lengths of different functional accessories need to be set to different lengths. Specifically, the rope length of the first separation rope 550 is less than the rope length of the second separation rope 560; the rope length of the second separation rope 560 is less than the rope length of the fifth connecting rope 15.

[0063] The specific working principle is as follows: When the main umbrella body 320 is fully deployed, the corner reflector assembly 500 continues to move forward due to inertia, at which point the fourth connecting rope 14 is fully taut. Depending on the length of the ropes, the sealing pin 530 fixed to the packaging bag 510 is first removed, leaving the inflatable corner reflector 520 in a free state. Simultaneously, the second separating rope 560 pulls the pull ring from the gas cylinder, causing the gas cylinder to inflate the corner reflector 520. Since these two steps occur instantaneously, when the fourth connecting rope 14 is fully taut, the connecting rope between the packaging bag 510 and the fourth connecting rope 14 is also taut, which can offset some of the overload and prevent damage to the inflatable corner reflector 520. Finally, the fifth connecting rope 15 is fully taut, causing the corner reflector system to fully deploy.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
