Among them, life-saving equipment bags are used to carry survival supplies, safety protection and communication equipment, etc., which are extremely important life-saving equipment.

[0003] There are two main ways to drop life-saving supplies: First, the life-saving supplies are directly loaded into the aircraft and dropped directly when the aircraft reaches the destination. This method has a low drop height and cannot meet the needs of some scenarios; second, the life-saving supplies are connected to a parachute and dropped from high altitude. This method is far away from the destination when landing, has poor drop accuracy, and the supplies are severely damaged when they fall to the ground. Therefore, there is an urgent need for a life-saving supplies package that can be dropped from high altitude with high drop accuracy and low landing damage. Summary of the invention

[0004] In order to overcome the technical defects of existing life-saving equipment packages that cannot simultaneously meet the requirements of high-altitude delivery, high delivery accuracy and low landing damage, the present invention provides a high-altitude parachute life-saving equipment package and a delivery method thereof.

[0007] Optionally, the zipper is L-shaped and covers two end surfaces and a side wall of the inner tube.

[0008] Optionally, both the outer side of the upper end plate and the outer side of the lower end plate are provided with a slot adapted to the zipper.

[0009] Optionally, a first buffer base is provided at the bottom of the coating.

[0010] Optionally, a handle is provided at the upper end of the coating.

[0011] Optionally, a second buffer base is provided at the bottom end of the barrel-shaped structure.

[0012] Optionally, the supporting mesh cover includes a plurality of coaxial connecting rings that are spaced apart along the axial direction, and the plurality of connecting rings are connected and fixed by vertical bars, the top ends of the vertical bars extend outwardly above the uppermost connecting ring and are connected to the connecting hanger, and the bottom ends of the vertical bars extend outwardly below the lowermost connecting ring and are connected to the second buffer base.

[0013] The method for delivering a parachute life-saving item package delivered from high altitude provided by the present invention comprises the following steps: S1. Connect the parachute rescue bag to the deceleration parachute and load it into the life-saving capsule from the tail end of the capsule; S2. The life-saving capsule is mounted horizontally on the drone and delivered to the sky above the target area; S3. The life-saving capsule is separated from the drone; S4. The life-saving capsule falls freely to a specified height; S5. The tail end of the life-saving capsule separates, and the deceleration parachute pulls the parachute-dropped life-saving equipment bag out of the capsule and descends to the target area as a whole.

[0014] Optionally, the parachute rescue equipment bag is provided with two, namely a main bag and a land bag.

[0016] The method for delivering a parachute life-saving item package delivered from high altitude provided by the present invention places the item package in a life-saving capsule and delivers it as a whole. After the life-saving capsule has fallen freely for a certain distance, the deceleration parachute will pull the item package out for low-speed landing. The delivery accuracy is related to the height of the item package falling at low speed. Therefore, the method can increase the delivery height while ensuring the delivery accuracy, thereby achieving high-altitude and high-precision delivery. At the same time, since the height of the item package falling at low speed is relatively reduced, the landing loss of the item package can be reduced. Combined with the unique internal and external multi-layer structure of the item package, the landing loss of the item package can be further reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] In the description, it should be noted that the terms "first" and "second" are only used for descriptive purposes and should not be understood as indicating or implying relative importance. It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The specific embodiments of the present invention are described in detail below with reference to the drawings. Example 1

[0025] The present embodiment provides a parachute rescue package for high-altitude delivery, comprising an inner tube 1, a coating 2, a dimensional tube 3 and a supporting mesh cover 4.

[0026] Inner tube 1 The inner tube 1 comprises an upper end plate 11 and a lower end plate 12 which are parallel to each other and a connecting wall connected between the upper end plate 11 and the lower end plate 12. The upper end plate 11, the lower end plate 12 and the connecting wall form a containing area for containing lifesaving items.

[0027] Specifically, the connecting wall includes two connecting strips 13, which are vertically arranged and fixed between the edge of the upper end plate 11 and the edge of the lower end plate 12. The two connecting strips 13 are connected by a skin 14, and the axial ends of the skin 14 extend to the upper end plate 11 and the lower end plate 12 respectively. The circumferential angle corresponding to the skin 14 is less than or equal to 180°. A pressure bar 15 is provided at the portion between the upper end plate 11 and the lower end plate 12 where the skin 14 is not provided. The pressure bar 15 is vertically arranged and detachably fixed between the edge of the upper end plate 11 and the edge of the lower end plate 12. The inner side wall of the connecting strip 13 is provided with a plurality of groups of receiving grooves distributed along the vertical intervals. The receiving grooves of the two connecting strips 13 are correspondingly arranged and at least one group of receiving grooves is clamped with a partition 16. When in use, first, at least one end of the pressure bar 15 is separated from the corresponding end plate, so that the area between the upper end plate 11 and the lower end plate 12 where the skin 14 is not provided forms an installation and removal opening. Since the circumferential angle of the skin 14 is less than or equal to 180°, the circumferential angle corresponding to the installation and removal opening is greater than or equal to 180°, and the partition 16 can be inserted into the accommodating area through the installation and removal opening and clamped on one of the receiving grooves, and then the pressure bar is locked. The arrangement of the partition 16 can divide the accommodating area into two or more chambers, so that the classified loading of items can be realized, and the design is more humane.

[0028] More specifically, the number and positions of the partitions 16 can be designed according to actual needs.

[0029] More specifically, one end of the pressure bar 15 is hinged and the other end is connected by a latch, that is, the upper end of the pressure bar 15 is hinged to the upper end plate 11 and the lower end is connected to the lower end plate 12 by a latch, or the lower end of the pressure bar 15 is hinged to the lower end plate 12 and the upper end is connected to the upper end plate 11 by a latch. When in use, the latch is removed and the pressure bar 15 is rotated to form the aforementioned opening. Of course, the detachable fixation of the pressure bar 15 can also be achieved by using structures such as bolts or magnetic attraction.

[0030] It should be noted that the above is only the preferred structure of the connecting wall designed in this embodiment, and a partition 16 is additionally provided based on this preferred structure; in other embodiments, the connecting wall may also eliminate the setting of the connecting strip 13 and the pressure bar 15, and no partition 16 is provided, and the corresponding angle of the skin 14 is 360°, that is, the skin 14 forms a cylindrical structure around a circle, and the two ends of the skin 14 are respectively connected to the upper end plate 11 and the lower end plate 12 and at least one end is detachably connected to enable the storage and access of life-saving items.

[0031] Coating 2 The coating 2 is wrapped around the outer side of the inner tube 1 and is provided with an opening for installing and removing the inner tube 1 , and the opening is opened and closed by a zipper 21 .

[0032] Specifically, the zipper 21 is L-shaped and covers the two end surfaces and the side wall of the inner tube 1. The L-shaped zipper 21 is more convenient for loading or removing the inner tube 1.

[0033] More specifically, the outer sides of the upper end plate 11 and the lower end plate 12 are both provided with a slot adapted to the zipper 21. The slot enables the zipper 21 to be placed in the slot after the inner tube 1 and the coating 2 are assembled, which can limit the coating 2 on the one hand, and prevent the zipper 21 from bulging and causing the coating 2 and the inner tube 1 to not fit tightly.

[0034] It should be noted that the above is only the preferred structure of the zipper 21 designed in this embodiment; in other embodiments, the zipper 21 can also be set to a straight shape or other shapes, as long as the inner tube 1 can be loaded into the coating 2 or taken out from the bag through the opening corresponding to the zipper 21.

[0035] Furthermore, a first buffer base 22 is provided at the bottom of the bag 2. The first buffer base 22 can be made of a flexible material with a buffering effect such as rubber. The buffer structure belongs to conventional means in the art and will not be described here. The design of the first buffer base 22 can improve the overall impact resistance of the article bag.

[0036] Furthermore, a handle 23 is provided at the upper end of the coating 2, which is more convenient for taking and placing.

[0037] Furthermore, double-sided coated waterproof fabric can be used as the main material of the coating 2, and through the sewing and heat-sealing process design, the item bag can meet the waterproof requirements, thereby taking into account the rescue needs in high-altitude areas, cold areas and marine environments.

[0038] Dimensional tube 3 The dimensional tube 3 is sleeved on the outside of the coating 2.

[0039] It should be noted that the dimensional tube 3 has two functions: first, to maintain the shape of the article package and protect the internal coating 2 and the inner tube 1; second, to increase the overall weight of the article package to meet the weight design requirements.

[0040] Support grille 4 The supporting mesh cover 4 is wrapped around the outer side of the dimensional tube 3 and the outer side of the lower end plate 12 to form a barrel-shaped structure, and a connecting hanger 41 is provided at the edge of the open end of the barrel-shaped structure.

[0041] Specifically, the connecting hanging member 41 is a hanging ring, and the spring mouth can be matched to realize the hanging connection during connection. Of course, the connecting hanging member 41 can also be a hook or other commonly used hanging connection structures.

[0042] Furthermore, a second buffer base 42 is provided at the bottom of the barrel. The second buffer base 42 can be made of a flexible material with a buffering effect such as rubber. The buffer structure belongs to conventional means in the art and will not be described here. The design of the second buffer base 42 can improve the overall impact resistance of the item bag.

[0043] Based on the design of the second buffer base 42, the support mesh cover 4 of this embodiment includes a plurality of coaxial connecting rings 43 spaced apart along the axial direction, and the plurality of connecting rings 43 are connected and fixed by vertical bars 44, the top ends of the vertical bars 44 extend outwards above the uppermost connecting ring 43 and are connected to the connecting hanger 41, and the bottom ends of the vertical bars 44 extend outwards below the lowermost connecting ring 43 and are connected to the second buffer base 42. This structure has a reliable connection and strong structural stability.

[0044] The assembly process of the parachute rescue bag delivered from high altitude in this embodiment is as follows: First, the pressure bar 15 of the inner tube 1 is rotated open by pulling out the pin installed thereon, a preset number of partitions 16 are inserted into the receiving groove according to the preset position, and the life-saving items are reasonably placed in the preset combination, and then the pressure bar 15 is closed and the pin is locked; the zipper 21 of the coating 2 is opened and laid flat on the ground, and the inner tube 1 is placed horizontally so that the zipper 21 is just inserted into the slot of the inner tube 1, and the coating 2 is covered and the zipper 21 is closed; the coating 2 is turned up to make it stand vertically, and two people work together to lift the handle 23 of the coating 2 and put it into the dimensional tube 3. It should be noted that the supporting mesh cover 4 needs to be assembled with the dimensional tube 3 in advance. At this point, the life-saving item package is assembled.

[0045] It should be noted that, by analyzing rescue missions in scenes such as sea, jungle, desert and alpine areas, the dimensional tube 3 of the life-saving equipment package can be sprayed with orange paint and the main material of the coating 2 can be made of fluorescent fabric to cope with sudden rescue missions in the wild and meet the high resolution of the life-saving equipment package in various harsh environments. Example 2

[0046] This embodiment provides a method for delivering a parachute life-saving item package delivered from a high altitude, comprising the following steps: S1. The parachute rescue package is connected to the deceleration parachute 5 and is sequentially loaded into the life-saving capsule from the tail end of the capsule; S2. The life-saving capsule is mounted horizontally on the drone and delivered to the sky above the target area; S3. The life-saving capsule is separated from the drone; S4. The life-saving capsule falls freely to a specified height; S5. The tail end of the life-saving capsule is separated, and the deceleration parachute 5 pulls the parachute-dropped life-saving item bag out of the capsule and descends to the target area as a whole.

[0047] Specifically, the parachute rescue equipment package is provided with two, namely a main bag 6 and a land bag 7. The bottom edge of the barrel of the barrel-shaped structure of the land bag 7 and the lower end of the deceleration parachute 5 are also provided with connecting hangers 41. The upper connecting hanger 41 of the land bag 7 is connected to the connecting hanger 41 of the deceleration parachute 5 by a spring buckle, and the lower connecting hanger 41 of the land bag 7 is connected to the connecting hanger 41 of the main bag 6 by a spring buckle.

[0048] It is easy to understand that both the main bag 6 and the land bag 7 include the article bag structure described in Example 1, with two differences: first, the sizes of the two are different; second, the land bag 7 is provided with connecting hangers 41 at both ends, while the main bag 6 is only provided with connecting hangers 41 at the upper end. The main bag 6 is used to carry general life-saving articles, such as food, medicine, communication equipment, etc.; the land bag 7 is used to carry tents, plateau oxygen generators, etc.

[0049] The above is only a specific implementation of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
