Description

Technical Field

[0001] This invention relates to the field of high-altitude balloons, and more particularly to a high-altitude balloon restraint release mechanism. Background Technology

[0002] Due to their large size, high-altitude balloons are difficult to control during inflation and ascent. To minimize changes in balloon attitude during inflation, both domestic and international methods employ flexible materials to wrap and restrain the balloon at specific locations. Once inflation reaches a certain level and the attitude stabilizes, the restraint mechanism is released. Therefore, before inflation, the release mechanism is gradually released along with the balloon body within a roller. The release mechanism, while fulfilling its restraint and release function without damaging the balloon body, should also be as lightweight and thin as possible to facilitate its integration with the balloon during ascent.

[0003] For example, patent application number 202010543833.8 discloses a high-altitude balloon restraint device, including a flexible binding strap and a locking mechanism. The locking component includes an eyelet buckle and a conical plug, which are respectively located at both ends of the flexible binding strap. The conical plug can be inserted into the eyelet buckle. The unlocking component includes a pin, one end of which is inserted into the conical plug, and the other end is used to connect to one end of a pull rope. Unlocking is achieved by manually pulling the rope. However, this device has poor structural reliability; the pin is prone to accidental detachment and jamming, and the pull rope is prone to accidental breakage, introducing many uncertainties during balloon launch. Therefore, how to develop a novel high-altitude balloon restraint release mechanism has become a problem urgently needing to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a high-altitude balloon restraint release mechanism.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention discloses a high-altitude balloon restraint release mechanism, comprising a flexible collar, a fixed plate, an electric telescopic cylinder, and a locking block. The flexible collar is made of elastic material, and a positioning plate is provided at the left end of the flexible collar, on which the electric telescopic cylinder is located. A locking block is provided at the right end of the flexible collar, and the locking block has a through hole that engages with the movable rod on the electric telescopic cylinder. During operation, the flexible collar is horizontally arranged around the outer surface of the high-altitude balloon body. After the left end of the flexible collar wraps around the high-altitude balloon body and overlaps with the right end of the flexible collar, the movable rod of the electric telescopic cylinder at the left end of the flexible collar is inserted into the through hole on the locking block at the right end of the flexible collar.

[0007] Furthermore, there are two electric telescopic cylinders, respectively located at the upper and lower ends of the positioning plate; the movable rod of the electric telescopic cylinder at the upper end of the positioning plate is located along the upper edge of the positioning plate; the movable rod of the electric telescopic cylinder at the lower end of the positioning plate is located along the lower edge of the positioning plate.

[0008] Furthermore, there are two locking blocks, which correspond to the electric telescopic cylinders at the upper and lower ends of the positioning plate, respectively.

[0009] Furthermore, a control box assembly is provided on the positioning plate, and the control box assembly is electrically connected to the electric telescopic cylinder.

[0010] Furthermore, the control box assembly contains a battery pack and a control system.

[0011] Furthermore, the positioning plate is riveted to the soft collar, and the electric telescopic cylinder is detachably mounted on the positioning plate by bolts.

[0012] Furthermore, the locking block is riveted to the soft collar.

[0013] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0014] This invention's high-altitude balloon restraint and release mechanism employs a combination of two sets of electrically operated telescopic cylinders with locking block holes for restraint. During release, the moving rods retract from the holes, and the pre-tension force during restraint quickly separates the wrapping mechanism, simplifying the restraint and release mechanism and making the response more rapid. Furthermore, this invention uses a soft collar of elastic material to wrap the high-altitude balloon; the elasticity of the wrapping material accelerates the separation speed during release, improving separation efficiency. In summary, this invention's high-altitude balloon restraint and release mechanism has a simple structure and high reliability. It effectively solves the problems of existing high-altitude balloon restraint devices that rely on manual rope pulling for unlocking, which suffers from poor structural reliability, accidental pin detachment and jamming, and accidental rope breakage, introducing numerous uncertainties during balloon launch.

[0019] like Figure 1 As shown, a high-altitude balloon restraint release mechanism includes a soft collar 1, a fixed plate 2, an electric telescopic cylinder 3, a locking block 5, and a control box assembly 4.

[0020] The soft collar 1 is made of elastic material. As the main body of the restraint mechanism, the soft collar 1 is made of a material with a certain degree of elasticity and is used to fix the connecting parts. At the same time, it is in direct contact with the high-altitude balloon and plays a role in protecting the high-altitude balloon capsule.

[0021] A positioning plate 2 is provided at the left end of the soft collar 1, and the positioning plate 2 is riveted to the soft collar 1.

[0022] The positioning plate 2 is the mounting surface for the electric telescopic cylinder 3. The electric telescopic cylinder 3 is mounted on the positioning plate 2. Specifically, the electric telescopic cylinder 3 is detachably mounted on the positioning plate 2 by bolts, facilitating future maintenance and repair of the electric cylinder 3.

[0023] There are two electric telescopic cylinders 3, which are respectively set at the upper end and the lower end of the positioning plate 2; the movable rod 6 of the electric telescopic cylinder 3 at the upper end of the positioning plate 2 is set at the upper edge of the positioning plate 2; the movable rod 6 of the electric telescopic cylinder 3 at the lower end of the positioning plate 2 is set at the lower edge of the positioning plate 2.

[0024] A locking block 5 is provided at the right end of the soft collar 1, and the locking block 5 is riveted to the soft collar 1. The locking block 5 has a through hole that cooperates with the movable rod 6 on the electric telescopic cylinder 3.

[0025] There are two locking blocks 5, which correspond to the electric telescopic cylinders 3 at the upper and lower ends of the positioning plate 2, respectively.

[0026] During operation, the soft collar 1 is horizontally arranged around the outer surface of the high-altitude balloon body. After the left end of the soft collar 1 wraps around the high-altitude balloon body and overlaps with the right end of the soft collar 1, the movable rod 6 of the electric telescopic cylinder 3 at the left end of the soft collar 1 is inserted into the through hole on the locking block 5 at the right end of the soft collar 1.

[0027] The positioning plate 2 is provided with a control box assembly 4, which is electrically connected to the electric telescopic cylinder 3.

[0028] The control box assembly 4 houses a battery pack and a control system. The control system includes a wireless remote control receiver, allowing personnel to operate and control the system from the ground, enabling remote control of the extension and retraction of the movable rod 6 of the electric telescopic cylinder 3.

[0029] The technical solution of this invention has a simple structure, making it easy to wrap and constrain high-altitude balloons. All components of the technical solution of this invention are miniaturized, saving space during wrapping and securing.

[0030] The operating principle of this invention is as follows:

[0031] When restraining a high-altitude balloon, the soft collar 1 surrounds the balloon body, and the movable rod 6 of the electric telescopic cylinder 3 is extended, passing through the through hole on the locking block 5 under a certain elastic pre-tightening force to achieve restraint.

[0032] When releasing the high-altitude balloon, the control box assembly 4 controls the movable rod 6 of the electric telescopic cylinder 3 to retract. The movable rod 6 disengages from the through hole of the locking block 5 and quickly separates and releases the high-altitude balloon by relying on the elastic force during release.

[0033] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
