Description

Technical Field

[0001] The invention belongs to the technical field of radar marine rescue, and in particular relates to an integrated device of an inflatable corner reflector and an inflatable life raft. Background Art

[0002] Traditional corner reflectors are mostly dihedral or trihedral structures made of metal plates. These corner reflectors are often rigid structures and difficult to combine with flying devices. Another type of inflatable flexible corner reflector is often used to simulate large ship targets and is dropped from the ship. It has a built-in automatic inflation device, but too much equipment makes it difficult to use it directly on pilots.

[0003] On the one hand, these traditional corner reflectors require manual fixing and inflation operations, which increases the molding time of the corner reflectors. For example, see Figure 1 The traditional inflatable corner reflector has a fan-shaped reflection angle. The reflective material is attached to the rubber ball, which contains three inscribed discs. The three discs are stretched into a mutually perpendicular fan-shaped corner reflector by inflating the ball. It is usually deflated and folded, and then packed into an inflatable life raft. It is inflated and formed in an emergency to be used as a life-saving signal. When using this corner reflector, the pilot needs to inflate it and then install it on the life raft, which is a cumbersome process. On the other hand, the space under the pilot's seat is limited. After placing the life raft, it is difficult to accommodate the support rods and inflatable devices of the corner reflector.

[0004] Therefore, current corner reflectors are less practical in marine rescue scenarios for pilots. Summary of the invention

[0005] The embodiment of the present invention provides an integrated device of an inflatable corner reflector and an inflatable life raft, which can solve the problem that the current corner reflector has poor practicality in the marine rescue scenario for pilots.

[0008] An inflatable corner reflector comprises a plurality of second inflatable columns and a reflecting surface. The second inflatable columns are interconnected to form an inflatable skeleton. The inflatable skeleton is arranged on the inflatable ceiling and is connected to the first inflatable columns. Part of the inflatable skeleton is exposed from the inflatable ceiling, and part of the inflatable skeleton is located between the inflatable ceiling and the bottom of the inflatable boat. The reflecting surface is fixed on the outer surface of the inflatable skeleton.

[0009] In a possible implementation of the first aspect, the first inflatable column includes a first sub-inflatable column, a second sub-inflatable column, and a third sub-inflatable column;

[0010] The first sub-inflatable column is obliquely connected to one side of the inflatable boat bottom and one end of the second sub-inflatable column, the third sub-inflatable column is obliquely connected to the other side of the inflatable boat bottom and the other end of the second sub-inflatable column, and the second sub-inflatable column is parallel to the inflatable boat bottom to form a trapezoidal space between the inflatable boat bottom and the inflatable roof.

[0011] In a possible implementation manner of the first aspect, the shape of the bottom of the inflatable boat includes a circle, a quadrilateral, or a shape formed by a combination of a circle and / or a quadrilateral.

[0012] In a possible implementation manner of the first aspect, the inflation device is a compressed carbon dioxide cylinder.

[0013] In a possible implementation manner of the first aspect, the inflatable skeleton is a spherical skeleton.

[0014] In a possible implementation manner of the first aspect, the inflatable frame is a cubic frame.

[0015] In a possible implementation manner of the first aspect, the integrated device is folded to form an outward-expanding pattern centered on the inflatable device.

[0016] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: according to the integrated device provided by the present invention, the corner reflector and the life raft are integrated into one design, so that the corner reflector can be stored together with the life raft and inflated and deployed together, without occupying additional space and without requiring the pilot who falls into the water to perform additional operations, which can reduce the volume and molding time of the corner reflector, simplify the use process of the corner reflector, and thus enhance the practicality of the integrated device; the inflatable corner reflector is arranged on an inflatable ceiling at a certain height from the sea level so that the inflatable corner reflector has a certain mounting height, which can reduce the influence of sea clutter.

[0027] In addition, in the description of the present specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0028] References to "one embodiment" or "some embodiments" etc. described in the present specification mean that one or more embodiments of the present invention include specific features, structures or characteristics described in conjunction with the embodiment.

[0029] The present invention is further described in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0030] Figure 2 The figure shows a scene schematic diagram of a scene in which an integrated device of an inflatable corner reflector and an inflatable life raft provided by an embodiment of the present invention is folded.

[0031] As an example, see Figure 2 In (a), the inflatable device is fixed inside the bottom of the inflatable boat. When the integrated device is folded, it can be folded toward the middle along the fold in the length direction (i.e., the direction indicated by arrow 201), and the part beyond the inflatable device is then folded back in the opposite direction. Figure 2 (b) in the figure, the inflatable device may then be wrapped around the inflatable device along the width direction (see the direction indicated by arrow 202) to wrap the entire inflatable device along the width direction. Figure 2 In (c), the folded integrated device can be folded into an expanded shape of the inflatable device, such as a cylindrical object with a volume close to that of the inflatable device. This can greatly reduce the storage space required for the integrated device.

[0032] For example, the folded integrated device can be stored under the pilot's seat like a life raft on a conventional aircraft. When the pilot and the seat are separated by a certain distance in an accident, the inflatable device inflates the integrated device and expands it into a life raft. Figure 3 The device shown has an inflatable corner reflector that reflects the electromagnetic signal of the radar, making it easier for search and rescue personnel to determine the pilot's location.

[0033] Figure 4 The structure diagram of an integrated device of an inflatable corner reflector and an inflatable life raft provided in an embodiment of the present invention is shown. As an example but not a limitation, the integrated device 400 may include an inflatable life raft 410 and an inflatable corner reflector 420 .

[0034] In some embodiments, see Figure 4The inflatable life raft 410 may include an inflatable bottom 411, a plurality of first inflatable columns 412, and an inflatable device 413. The two ends of the first inflatable columns 412 are respectively connected to the two sides of the inflatable bottom to form an inflatable roof above the inflatable bottom, and the inflatable device 413 is fixed inside the inflatable bottom. The inflatable corner reflector 420 may include a plurality of second inflatable columns 421 and a reflecting surface 422, and the second inflatable columns are connected to each other to form an inflatable frame (see Figure 4 401), the inflatable frame can be arranged on the inflatable roof of the inflatable life raft 410, with a portion exposed from the inflatable roof and the rest located between the inflatable roof and the inflatable bottom 411. The reflective surface 422 can be fixed on the inflatable frame.

[0035] Exemplarily, the inflatable frame and the inflatable ceiling are interconnected and internally connected, so that the inflatable ceiling can support the inflatable corner reflector 420 and serve as a medium to inflate it.

[0036] In a possible implementation, the inflatable boat bottom 411 may be circular (see Figure 5 (a) in), quadrilateral (see Figure 5 (b) in the figure), circular and / or quadrilateral combined images (see Figure 4 ).

[0037] In one possible implementation, see Figure 5 In (b), the first inflatable column 412 may include a first sub-inflatable column 4121 , a second sub-inflatable column 4122 and a third sub-inflatable column 4123 .

[0038] For example, see Figure 5 In (b), the first sub-inflatable column 4121 is obliquely connected to one side of the inflatable boat bottom 411 and one end of the second sub-inflatable column 4122, and the third sub-inflatable column 4123 is obliquely connected to the other side of the inflatable boat bottom 411 and the other end of the second sub-inflatable column 4122; and the second sub-inflatable column 4122 is parallel to the inflatable boat bottom 411 to form a trapezoidal space above the inflatable boat bottom 411.

[0039] Optionally, the first inflatable column 412 may also be of an integrated design, with two ends of an inflatable column respectively connected to two sides of the inflatable boat bottom 411 to form a semicircular space above the inflatable boat bottom.

[0040] In a possible implementation, the inflation device 413 may be a compressed carbon dioxide cylinder.

[0041] In one example, the inflatable device 413 can be fixed in an inflatable buoy inside the inflatable boat bottom 411, and the valve of the gas cylinder can be controlled by a latch.

[0042] When the pilot and the seat are separated by a certain distance, the cutter pin is pulled out, and the integrated device 400 is automatically inflated and deployed to reflect the electromagnetic waves irradiated to the integrated device 400, thereby increasing the probability of the pilot falling into the water being detected by radar.

[0043] In a possible implementation, the inflatable skeleton may be a spherical skeleton or a cubic skeleton.

[0044] Exemplarily, the inflatable frames may be symmetrically distributed on both sides of the inflatable roof.

[0045] Exemplarily, the inflatable frame can be arranged at a position about 1 / 4 of the inflatable roof away from the center. After climbing onto the life raft, the pilot who falls into the water can sit on the side away from the inflatable corner reflector 420 .

[0046] In one example, if the inflatable frame is a spherical frame, the second inflatable column 421 can be a circular column, a semicircular column or a cylindrical column.

[0047] Specifically, see Figure 5 In (a), the inflatable skeleton may include two symmetrical upper and lower parts, either part of which is a hemisphere, consisting of two semicircular ring columns, one ring column and five cylindrical columns. One end of the five cylindrical columns are connected together, and the other ends point to five directions of the three-dimensional space respectively, and every two adjacent cylindrical columns are perpendicular to each other. The end points of the ring column connected to the five cylindrical columns are in the same plane, and are connected to the other ends of the four cylindrical columns on the plane. The two semicircular ring columns pass through the other end of the remaining cylindrical column, and the planes of the two semicircular ring columns are perpendicular to each other and to the plane of the ring column. The interiors of all the columns are interconnected.

[0048] In another example, if the inflatable frame is a cubic frame, the second inflatable columns 421 may be cylindrical columns.

[0049] For example, see Figure 6 In (a) and (b), the cylindrical inflatable columns can be first connected to form a triangle or a quadrilateral, and then a plurality of triangle / quadrilateral frames can be used to form a cubic structure.

[0050] In a possible implementation, the reflective surface 422 may be a metal mesh reflective surface.

[0051] Exemplarily, the reflective surface 422 may be made of common metal material and fixed to the inflatable frame via aramid ropes.

[0052] In one example, the mesh spacing of the wire mesh can be determined according to the operating frequency of the radar. The mesh spacing is usually less than one tenth of the wavelength of the radar.

[0053] Exemplarily, the reflective surface 422 may include 8 pieces, and every three adjacent reflective surfaces are in a right-angled state to form a corner reflector structure. After inflation, it can produce a radar reflection effect in all directions, and can ensure that there is always a reflective surface facing the radar irradiation direction, so as to reflect the electromagnetic waves back.

[0054] In some embodiments, the integrated device 400 may be disturbed by waves and sea breezes when floating on the sea, causing deviations in the surface contour of the reflecting surface, thereby affecting the reflection performance of the inflatable corner reflector 420; therefore, the inflatable corner reflector 420 may also include a waterproof mesh 423, which may cover the outer layer of the inflatable corner reflector 420 to prevent interference from the marine environment.

[0055] In a possible implementation, the waterproof mesh may be made of polyvinyl chloride material.

[0056] According to the integrated device provided by the present invention, the corner reflector and the life raft are integrated so that the corner reflector can be stored and inflated and deployed together with the life raft, without taking up additional space and without requiring the pilot who falls into the water to perform additional operations, which can reduce the volume and molding time of the corner reflector and simplify the use process of the corner reflector, thereby enhancing the practicality of the integrated device; the inflatable corner reflector is arranged on an inflatable ceiling at a certain height from the sea level so that the inflatable corner reflector has a certain mounting height, which can reduce the influence of sea clutter. Furthermore, the outward expansion pattern of the inflatable device formed by the folded integrated device can reduce the volume of the integrated device and overcome the problem of insufficient storage space on the aircraft.

[0057] In the above embodiments, the description of each embodiment has its own emphasis. For the part that is not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.
