Description

[0002] A corner reflector is an electromagnetic wave reflecting device made of metal sheet, and its specifications can be customized according to specific application requirements. This device can reflect electromagnetic waves of different incident angles and frequencies along their original path, generating significant reflected signals, thus having wide application value in many fields. In radar detection systems, corner reflectors can form strong reflective targets, serving a warning function, and are particularly suitable for safety fields such as maritime distress rescue and ship navigation. They are also of significant application value in low visibility conditions such as foggy weather. Currently, radar corner reflectors are mainly deployed on the sea surface or land by gravity sliding or external force launching, serving as artificially deployed radar decoys for radar jamming.
[0003] To ensure the corner reflector device can descend slowly, a dedicated descent control system is usually required. However, due to the presence of the descent control system, it needs to be separated from the corner reflector device and the cartridge case that encloses them in stages.

[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 , Figure 2 As shown, the projectile device provided in this embodiment includes: a cartridge case body 100, a first connecting rope 200 and a second connecting rope 300; the cartridge case body 100 is connected to the launching device 10 via a separating rope 11, and the launching device 10 is configured to generate a driving force for launching the cartridge case body 100, thereby using the driving force generated by the launching device 10 to launch the cartridge case body 100.
[0044] The cartridge case body 100 has a first cavity and a second cavity inside. The first cavity is used to install the slow descent device 20, and the second cavity is used to install the corner reflector device 30. That is, in the non-firing state, the slow descent device 20 and the corner reflector device 30 are two different chambers.
[0045] The first connecting rope 200 is disposed in the first cavity. One end of the first connecting rope 200 is connected to the inner wall of the cartridge case body 100, and the other end of the first connecting rope 200 is connected to the descent control device 20. One end of the second connecting rope 300 is connected to the descent control device 20, and the other end of the second connecting rope 300 is connected to the corner reflector device 30.
[0046] After the cartridge case body 100 is launched by the launching device 10, the cartridge case body 100 hovers in the air. When it reaches the designated airspace, the separation rope 11 tightens, causing the cartridge case body 100 to stop. The deceleration device 20 and the corner reflector device 30 continue to fly forward due to inertia. At this time, both the first connecting rope 200 and the second connecting rope 300 are in a slack state. Subsequently, the first connecting rope 200 tightens, causing the deceleration device 20 to stop, thereby enabling the guide parachute in the deceleration device 20 to be pulled out. At this time, the second connecting rope 300 is still in a slack state. Due to inertia, the corner reflector device 30 continues to hover in the air. Subsequently, the second connecting rope 300 is fully tightened, realizing the staged separation of the corner reflector device 30, the deceleration device 20 and the cartridge case body 100.
[0047] The projectile device provided in this embodiment, by installing the deceleration device 20 and the corner reflector device 30 respectively in the first cavity and the second cavity formed inside the projectile body 100, after the launching device 10 launches the projectile body 100, when it reaches the designated airspace, the separation rope 11 is tightened, causing the projectile body 100 to stop. Due to the setting of the first connecting rope 200, the deceleration device 20 will continue to move forward due to inertia, realizing the separation of the deceleration device 20 from the projectile body 100. After the first connecting rope 200 is tightened, the deceleration device 20 stops. Due to the setting of the second connecting rope 300, the corner reflector device 30 will continue to move forward due to inertia until the second connecting rope 300 is tightened, thereby realizing the separation of the corner reflector device 30 from the deceleration device 20. The gradual separation of the deceleration device 20 and the corner reflector device 30 can be achieved without the need for mechanical and electrical structures, alleviating the technical problems of the traditional corner reflector launching device 10 in the prior art, which relies on mechanical and electrical structures to achieve multi-stage separation, resulting in complex structure and high cost.
[0048] Regarding the structure and shape of the cartridge case body 100, specifically:
[0049] The cartridge case body 100 includes a first cartridge case 110, which is a cylindrical structure with one end sealed. The sealed end is located near the launching device 10. A first cavity is formed inside the first cartridge case 110, so that the deceleration device 20 is placed inside the first cartridge case 110. A first connecting rope 200 is located inside the first cartridge case 110. One end of the first connecting rope 200 is connected to the deceleration device 20, and the other end of the first connecting rope 200 is connected to the inner wall of the first cartridge case 110, thereby connecting the first cartridge case 110 and the deceleration device 20 through the first connecting rope 200.
[0050] Furthermore, a cartridge case 110 is provided with a cartridge case hanging ring 111 on its outer surface. The cartridge case hanging ring 111 is used to connect the separation rope 11. Specifically, one end of the separation rope 11 is connected to the cartridge case hanging ring 111, and the other end of the separation rope 11 is connected to the launching device 10. After the launching device 10 launches the first cartridge case 110, when the first cartridge case 110 reaches the designated airspace, the separation rope 11 is tightened, causing the first cartridge case 110 to stop, thereby realizing the separation of the deceleration device 20 from the first cartridge case 110.
[0051] Furthermore, the cartridge case body 100 also includes a second cartridge case 120; a second cavity is formed inside the second cartridge case 120, one end of the second connecting rope 300 extends into the second cavity and is connected to the corner reflector device 30, and the other end of the second connecting rope 300 extends into the first cavity and is connected to the descent device 20.
[0052] Specifically, the second cartridge case 120 includes two oppositely arranged cartridge case halves 121; the two cartridge case halves 121 merge to form a second cavity. It should be noted that the two cartridge case halves 121 merge but are not fixedly connected, ensuring that during the airborne process, the two cartridge case halves 121 can be split open in the air by wind force, thereby throwing out the corner reflector device 30.
[0053] In an optional embodiment, the second cartridge case 120 further includes a rear end cover 122; the rear end cover 122 is disposed in the opening at one end of the two cartridge case halves 121 near the first cartridge case 110; the rear end cover 122 is provided with a through hole for the second connecting rope 300 to pass through, thereby connecting the second connecting rope 300 to the descent device 20 and the corner reflector device 30; the outer circumferential surface of the rear end cover 122 is provided with a rear protrusion 123, and the end of the cartridge case half 121 near the descent device 20 is recessed to form a rear locking groove, and the rear protrusion 123 extends into the rear locking groove, thereby effectively preventing the cartridge case half 121 from rotating in the circumferential direction and restricting the cartridge case half 121 to only unfold outward in half due to wind force.
[0054] In an optional embodiment, the second cartridge case 120 further includes a front end cover 124; two front end covers 124 are provided, and the two front end covers 124 are respectively provided in the openings of the two cartridge case halves 121 away from the first cartridge case 110; the end face of the cartridge case half 121 away from the descent device 20 has a semi-conical concave surface, and the two cartridge case halves 121 are combined to form a conical concave surface. The setting of the conical concave surface allows the wind force acting on the conical concave surface during flight to cause the two cartridge case halves 121 to unfold outward in half.
[0055] The outer circumferential surface of the front cover 124 is provided with a front protrusion 125. The end of the cartridge half shell 121 away from the slow-descent device 20 is recessed to form a front locking groove. The front protrusion 125 extends into the front locking groove, thereby effectively preventing the cartridge half shell 121 from rotating in the circumferential direction and restricting the cartridge half shell 121 to only unfold outward in half due to wind force.
[0056] In summary, the projectile device provided in this embodiment achieves the gradual separation of the descent control device 20 and the corner reflector device 30 through ingenious structural design, and has the following technical effects:
[0057] 1. Simplify structural design
[0058] In the prior art, traditional corner reflector emitting devices 10 typically rely on complex mechanical structures (such as springs, latches, etc.) and electrical structures (such as trigger circuits, sensors, etc.) to achieve multi-stage separation. These structures not only increase the complexity of the device, but may also lead to separation failure due to component failure or electrical signal malfunction.
[0059] This embodiment achieves separation without additional mechanical or electrical components by utilizing the principle of inertia and the tensile force of the connecting rope. Specifically: the first connecting rope 200 separates the descent device 20 from the cartridge case body 100; the second connecting rope 300 further separates the corner reflector device 30 from the descent device 20.
[0060] It significantly reduces the complexity of the device and reduces the risk of failure due to mechanical or electrical components.
[0061] 2. Reduce costs
[0062] By eliminating complex mechanical and electrical structures, this embodiment significantly reduces production costs.
[0063] 3. Improve reliability
[0064] By utilizing the principles of inertia and the tension of the connecting rope, malfunctions that may occur with traditional mechanical and electrical structures (such as jamming, short circuits, and poor contact) are avoided. This non-powered design exhibits higher stability in extreme environments (such as high temperature, low temperature, and high humidity), thereby improving the overall system reliability.
[0065] Based on the above, such as Figure 3 As shown, the corner reflector launching system provided in this embodiment includes a launching device 10 and a projectile device; the launching device 10 is connected to the projectile body 100 via a separation rope 11, and the launching device 10 is configured to generate a driving force for launching the projectile body 100.
[0066] Specifically, the launching device 10 has an inflatable drive component that launches the cartridge case body 100 using high-pressure gas.
[0067] In an optional embodiment, the launching device 10 includes a barrel 12; a launching cavity is formed inside the barrel 12, the launching cavity is used to accommodate the cartridge case body 100, high-pressure gas is delivered into the launching cavity, thereby launching the cartridge case body 100 from the launching cavity, and a separation rope 11 is disposed in the launching cavity.
[0068] In an optional embodiment, the cartridge case body 100 further includes a sealing ring 400; a sealing groove is provided on the outer surface of the first cartridge case 110 along the circumferential direction, and the sealing ring 400 is installed in the sealing groove. The sealing ring 400 is used to seal the cartridge case body 100 and the gun barrel 12. It should be noted that the installation position of the sealing ring 400 is located on the outer circumferential surface of the first cartridge case 110 to ensure that high-pressure gas will not leak in the firing chamber.
[0069] Since the technical effects of the corner reflector launching system provided in this embodiment are the same as those of the projectile device provided in the above embodiments, they will not be described again here.
[0070] 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.
