Description

Technical Field

[0001] The invention relates to the technical field of aerostats, and in particular to a heavy-load high-altitude balloon launching device. Background Art

[0002] A heavy-load high-altitude balloon refers to a high-altitude balloon with a take-off weight of more than 100 kg. A heavy-load high-altitude balloon has a large load, a large amount of air inflated on the ground, and a large sphere size formed when inflated. When it is released, large-scale dynamic release equipment is required to reduce impact and improve safety.

[0003] During the release process of a heavy-loaded high-altitude balloon, there is a risk of being blown away by the wind because the lower part of the sphere is in a folded state. Once the lower part of the sphere is blown away by the wind, a structure similar to a sail will be formed, rapidly increasing the windward area. Even if the wind speed is low, it will generate huge resistance, which may cause damage to the sphere or make it impossible to release it. In serious cases, the flexible restraint may fail and fall off. After the flexible restraint falls off, the entire sphere will form a huge sail, greatly increasing the windward area and the force on the bottom of the sphere, which may cause damage to the sphere or premature detachment of the restraint structure of the release equipment or damage to the release equipment, posing a serious threat to release safety.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Combine the following Figure 1-Figure 11 The heavy-load high-altitude balloon launching device of the present invention is described.

[0031] like Figure 1 As shown in the figure, during the release process of the high-altitude balloon, its lower part is in a folded state. When the lower part is blown open by the wind, it forms a Figure 1 The sail-like structure shown in FIG. 1 causes the windward area to increase rapidly. When the flexible restraint falls off, the upper and lower parts of the sphere are connected to form a Figure 2 The huge sail shown greatly increases the windward area, which can easily cause damage to the balloon or the launching device. Based on this, an embodiment of the present invention provides a heavy-load high-altitude balloon launching device to solve this problem.

[0032] like Figure 3 As shown, in an embodiment of the present invention, a heavy-load high-altitude balloon dispensing device includes: a sphere 1, a flexible cylinder 5, an inflation mechanism, and a dispensing mechanism. The sphere 1 includes a sphere unfolding portion 11 and a sphere folding portion 12. The flexible cylinder 5 is sleeved on the outside of the sphere folding portion 12, and one end of the sphere folding portion 12 extends outside the flexible cylinder 5. The flexible cylinder 5 is used to constrain the sphere folding portion 12. Part of the inner wall of the flexible cylinder 5 is fixedly connected to the sphere folding portion 12. The flexible cylinder 5 is provided with an easy-tear structure. The easy-tear structure can be automatically disconnected during the expansion of the sphere 1 to release the constraint on the sphere folding portion 12 and expand the sphere folding portion 12. The inflation mechanism is connected to the sphere 1, and the dispensing mechanism is connected to the sphere folding portion 12.

[0033] Specifically, before the heavy-load high-altitude balloon is released, the upper part of the sphere 1 is in a flat state as the sphere unfolding part 11, and the lower part of the sphere 1 is in a folded state as the sphere folding part 12. The inflation mechanism is connected to the sphere unfolding part 11 and is used to inflate the sphere unfolding part 11. The release mechanism is connected to the sphere folding part 12 and is used to release the sphere 1.

[0034] The flexible cylinder 5 is sleeved outside the folded part 12 of the ball, and plays a restraining role on the folded part 12 of the ball, which can prevent the folded part 12 of the ball from being blown away by the wind during the lifting of the ball 1, forming a structure similar to a sail. When the ball 1 is lifted off the ground and rises to the level flight altitude, the inside of the ball 1 continues to expand as the atmospheric pressure decreases during the ascent, and the top of the flexible cylinder 5 begins to be stressed. When the force borne by the tearable structure exceeds the strength limit of the tearable structure, the tearable structure breaks, and the flexible cylinder 5 releases the constraint on the folded part 12 of the ball, and the ball 1 continues to expand until it is full.

[0035] In this embodiment, when the flexible cylinder 5 is sleeved on the spherical folding part 12, part of the flexible cylinder 5 is welded to the spherical folding part 12. When the tearable structure is disconnected, the flexible cylinder 5 is always fixed on the spherical 1 and will not fall off. This arrangement can ensure that the spherical 1 continues to expand without being affected, and on the other hand, it will not cause other risks due to the falling off of the flexible cylinder 5. It should be noted that once the flexible cylinder 5 falls off, it may hang on the pod 43, antenna and other positions after floating down, or be entangled on the parachute, which will affect the normal operation of the system. Therefore, the fixing point of the flexible cylinder 5 and the spherical folding part 12 needs to have high welding strength and good firmness.

[0036] In this embodiment, the thickness of the flexible tube 5 can be reduced at a certain place along the length direction during the manufacturing process to form a weak point, where an easy-to-tear structure is formed; or a tearing structure is provided on the wall surface of the flexible tube 5 along the length direction to form an easy-to-tear structure. The tearing structure described here can be similar to the discontinuous line structure on toilet paper.

[0037] The heavy-loaded high-altitude balloon launching device provided in the embodiment of the present invention can provide a flexible cylinder at the folded part of the sphere to constrain the folded part of the sphere during the launch of the sphere, thereby preventing the folded part of the sphere from being blown away by the wind, thereby ensuring the safe and effective launch of the heavy-loaded high-altitude balloon.

[0038] In the embodiment of the present invention, the flexible cylinder 5 is a cylindrical member formed by a flexible film. The material of the flexible film is a material that can be welded to the sphere 1. Further, the material of the flexible film can also be the same as or similar to the material of the sphere 1. Optionally, the material of the flexible film can be a low-temperature resistant polyethylene film. The thickness of the flexible film can be selected according to the strength and weight requirements of the flexible cylinder 5. The flexible cylinder 5 can be installed on the sphere 1 during the processing of the sphere 1.

[0039] like Fig. 9 and Fig.10 As shown, in one embodiment of the present invention, two ends of the flexible film are butt-jointed to form a flexible cylinder 5, and the two ends of the flexible film are welded to form a first weld 51, and the first weld 51 forms an easy-to-tear structure.

[0040] Specifically, in this embodiment, during the manufacturing process of the sphere 1, the middle position of the flexible film is welded to the sphere 1, and the welding strength must meet the strength requirement that the weld will not fall off during the expansion process of the sphere 1. The lower part of the sphere 1 is folded to form a sphere folded portion 12, and then the two ends of the flexible film are butt welded to form a first weld 51. In this embodiment, the strength of the first weld 51 is relatively low. During the expansion process of the sphere 1, the first weld 51 will be torn, causing the flexible cylinder 5 to break, thereby ensuring that the sphere 1 can continue to expand.

[0041] Optionally, in another embodiment of the present invention, the flexible cylinder 5 is provided with a tear line along the extension direction of its length, and the tear line forms an easy-to-tear structure.

[0042] Specifically, in this embodiment, the flexible cylinder 5 is a cylindrical member made of a flexible film. After the flexible cylinder 5 is sleeved on the outside of the spherical folding portion 12, part of the inner wall of the flexible cylinder 5 is welded to the spherical folding portion 12, and the welding strength must meet the strength requirement that the welding part will not fall off during the expansion of the spherical body 1. A tear line is provided on the flexible cylinder 5, and the structure of the tear line can be in the form of an intermittent fracture. During the expansion of the spherical body 1, the tear line is relatively low in strength, so that the flexible cylinder 5 is broken, thereby ensuring that the spherical body 1 can continue to expand.

[0043] like Fig.11 As shown, in another embodiment of the present invention, the flexible cylinder 5 is provided with an opening along the extension direction of its length, and the parts of the flexible cylinder 5 located on both sides of the opening are welded to the spherical folding part 12 to form a second weld 52, and the second weld 52 forms an easy-to-tear structure.

[0044] Specifically, in this embodiment, during the manufacturing process of the sphere 1, the middle position of the flexible film is welded to the sphere 1, and the welding strength must meet the strength requirement that the weld will not fall off during the expansion of the sphere 1. The lower part of the sphere 1 is folded to form a sphere folding portion 12. The difference between this embodiment and the first embodiment is that the two ends of the flexible film are no longer butted, but are respectively welded to the sphere folding portion 12, with a certain gap between the two ends to form an opening. In this arrangement, since the flexible film does not form a closed structure, during the expansion of the sphere 1, the second weld 52 is easier to separate from the sphere folding portion 12, thereby ensuring that the sphere 1 continues to expand.

[0045] like Figure 3 and Figure 4 As shown, in an embodiment of the present invention, the heavy-loaded high-altitude balloon launching device also includes a flexible constraint member 2, part of which is sleeved on the outside of the sphere 1, and the remaining part of the flexible constraint member 2 is sleeved on the outside of the flexible cylinder 5, and the flexible constraint member 2 separates the sphere 1 into a sphere unfolding portion 11 and a sphere folding portion 12.

[0046] Specifically, the flexible constraint 2 is a circle of constraint structure installed below the release line of the sphere 1. The two ends of the flexible constraint 2 are respectively sleeved on the outside of the sphere and the flexible cylinder 5, which tightens the flexible cylinder 5 like a bow tie to prevent the gas in the sphere expansion part 11 from entering the sphere folding part 12. In this embodiment, while the flexible constraint 2 prevents the gas in the sphere expansion part 11 from entering the sphere folding part 12, the flexible cylinder 5 can restrain the sphere folding part 12, thereby preventing the wind from blowing the sphere folding part 12 open, thereby preventing the sphere folding part 12 from being stretched open from two aspects.

[0047] Furthermore, the heavy-load high-altitude balloon launching device also includes an exhaust pipe, which is connected to the folded portion 12 of the ball. The bottom of the flexible cylinder 5 is located above the exhaust pipe and the distance between the bottom and the exhaust pipe is less than 2 meters.

[0048] like Figure 4 As shown, in an embodiment of the present invention, the inflation mechanism includes: an inflation tube 3 and an air source, and the air source is connected to the sphere expansion part 11 through the inflation tube 3 to inflate the sphere expansion part 11 to expand the sphere expansion part 11.

[0049] like Figure 4 As shown, in an embodiment of the present invention, the dispensing mechanism includes a dispensing roller 41, which is used to constrain and fix the ball unfolding part 11. The dispensing roller 41 is arranged at the dispensing line of the ball 1, and a flexible restraining member 2 is installed below the dispensing line.

[0050] Furthermore, the dispensing mechanism also includes: a cable 42 , a pod 43 and a dispensing vehicle 44 , the two ends of the cable 42 are respectively connected to the spherical folding portion 12 and the pod 43 , and the pod 43 is connected to the dispensing vehicle 44 .

[0051] The following combination Figure 5 , Figure 6 , Figure 7 and Figure 8 The launching process of the heavy-load high-altitude balloon launching device provided by an embodiment of the present invention is described in detail.

[0052] Before dispensing, the sphere 1 is spread on the ground with the flexible cylinder 5 sleeved on the sphere folded portion 12. Helium is inflated into the sphere 1 to a specified value through the inflation tube 3, and the sphere 1 is almost completely inflated to form an inverted water drop-shaped bubble, while the portion below the dispensing roller 41 is nearly straight under the straightening effect of the dispensing roller 41 and the dispensing vehicle 44.

[0053] like Figure 5 As shown, the dispensing drum 41 is opened, and the ball unfolding portion 11 stands up and gradually approaches upright. The ball folding portion 12 below the flexible constraint 2 is in an unfolded folded state due to the constraint of the flexible cylinder 5, and is close to a cylindrical shape.

[0054] The delivery vehicle 44 moves with the sphere 1 and adjusts the speed and the direction of travel according to the wind force and direction. When the sphere 1 to the pod 43 is close to vertical, the constraints between the delivery vehicle 44 and the pod 43 are released in time according to the ground wind force and direction, the pod 43 and the delivery vehicle 44 fall off, and the sphere 1 is lifted off the ground as a whole, completing the delivery.

[0055] After the sphere 1 is lifted off the ground, the flexible restraint 2 is released by ground remote control, automatic time delay control or automatic pressure detection control, and the flexible restraint 2 falls to the ground by itself. After the flexible restraint 2 is released, as the sphere 1 rises, the air pressure decreases, and the buoyant gas in the sphere 1 expands. Figure 6 and Figure 7 As shown, the top of the flexible cylinder 5 begins to bear force, and after exceeding the bearing limit of the tearable structure on the flexible cylinder 5, the tearable structure of the flexible cylinder 5 gradually tears open until it is completely torn from top to bottom, releasing the constraint on the folded portion 12 of the ball. Figure 8 As shown, after the flexible cylinder 5 is completely disconnected, the flexible cylinder 5 is still connected to the ball 1 until the ball is completely inflated.

[0056] It should be noted that the automatic release method of the flexible restraining member 2 can refer to the prior art, so it will not be described here in detail.

[0057] The heavy-loaded high-altitude balloon launching device provided in the embodiment of the present invention can wrap the folded part of the ball during the inflation and launching process to prevent it from being blown away by the wind to form a wind pocket, thereby reducing the launching risk and improving the launching capacity and safety; at the same time, after the balloon is launched and the flexible restraint is released, the flexible cylinder can automatically tear as the ball expands to release the restraint. After the restraint is released, the flexible cylinder is still suspended on the ball and will not fall off, thereby not affecting the safety of the ball and other components of the heavy-loaded high-altitude balloon launching device, thereby improving the safety of the heavy-loaded high-altitude balloon launching device.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
