Description

Technical Field

[0001] The present invention relates to the field of aerospace equipment technology, and in particular to an extendable release mechanism for separating a communication antenna of a lunar soil penetrator. Background Art

[0002] During penetrating exploration missions targeting extraterrestrial bodies, the penetrating probe must expose its communication antenna to maintain communication with the communication satellite. To prevent the antenna from breaking or being damaged by the significant overload during high-speed penetration, the antenna must be coiled and secured to the penetrating probe's base before and during landing. Once penetration is complete and the probe's state stabilizes, the antenna can be smoothly deployed and exposed to the surface for on-orbit communication.

[0003] Therefore, antennas suitable for penetrating reconnaissance missions must be able to stably fold during in-orbit flight and penetration, and successfully deploy after landing and penetration. Currently, in the field of penetrating reconnaissance instruments, both domestically and internationally, a separation of stages is often employed, with the penetrating and communication stages separating during landing. However, this separation process carries the risk of structural failure. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the risk of structural failure during the separation process of the antenna in the penetrating exploration mission mode in the prior art, and thus provide an extendable release mechanism for separating the communication antenna of the lunar soil penetrating missile.

[0005] In order to solve the above technical problems, the present invention provides an extendable release mechanism for separating the communication antenna of a lunar soil penetrator, comprising: a main body, the main body comprising a first mounting surface and a second mounting surface, the first mounting surface and the second mounting surface being arranged at an angle; an antenna vibrator, arranged on the first mounting surface, and a locking ring is provided on the antenna vibrator, the locking ring being used to lock the antenna vibrator; a superelastic conductive part, sleeved on the second mounting surface; a burning wire release mechanism, the burning wire release mechanism being arranged on the superelastic conductive part, and one end of the burning wire release mechanism is connected to the locking ring, and the other end is connected to the second mounting surface away from an end of the first mounting surface.

[0006] Furthermore, the burning wire release mechanism includes: a plurality of positioning rings, which are arranged at intervals on the locking ring and the outer wall of the main body; and a connecting wire that passes through the positioning rings and is used to connect the positioning rings.

[0007] Furthermore, the positioning rings on the main body and the positioning rings on the locking ring are arranged alternately.

[0008] Furthermore, the connecting line is made of Kevlar fiber material.

[0009] Furthermore, the superelastic conductive member is coaxially arranged with the main body.

[0010] Furthermore, the superelastic conductive member is made of a superelastic cable.

[0011] Furthermore, the main body includes: a first fixing ring and a second fixing ring, the diameter of the second fixing ring is larger than the diameter of the first fixing ring, and the outer wall surface of the first fixing ring is the first mounting surface; a connecting ring, arranged between the first fixing ring and the second fixing ring, the connecting ring is inclined to the first fixing ring and the second fixing ring, and the outer wall surface of the connecting ring is the second mounting surface.

[0012] Furthermore, the main body is an integrally formed structure.

[0013] Furthermore, it also includes: a support ring embedded in the first fixing ring; a support seat provided in the connecting ring and the second fixing ring, and the support seat is connected to the support ring.

[0014] The technical solution of the present invention has the following advantages:

[0015] 1. The extendable release mechanism for separating the communication antenna of a lunar soil penetrator provided by the present invention includes: a main body, the main body including a first mounting surface and a second mounting surface, the first mounting surface and the second mounting surface being arranged at an angle; an antenna vibrator, arranged on the first mounting surface, and provided with a locking ring on the antenna vibrator, the locking ring being used to lock the antenna vibrator; a superelastic conductive member, sleeved on the second mounting surface; a burning wire release mechanism, the burning wire release mechanism being arranged on the superelastic conductive member, and one end of the burning wire release mechanism is connected to the locking ring, and the other end is connected to the second mounting surface away from an end of the first mounting surface.

[0016] By providing first and second mounting surfaces on the main body, mounting surfaces for the antenna element and the superelastic conductive element are provided, facilitating their installation. A locking ring is also provided on the antenna element, effectively securing it to the first mounting surface of the main body. A firing wire release mechanism is connected to the locking ring at one end and to the second mounting surface of the main body at the other. During the penetrating probe's ground penetration, a high overload triggers the onboard acceleration acquisition system. Real-time monitoring of the acceleration data signal indicates that the probe has completed the landing penetration phase. The firing wire release mechanism then activates and deactivates. The superelastic guide pushes the locking ring open, pushing the antenna element 0.5 to 1 meter out of the orbit, enabling communication between the penetrating probe and the main body. This firing wire release mechanism eliminates the risk of failure of the extendable release mechanism that separates the communication antenna of the lunar regolith penetrating probe.

[0018] 3. The extendable release mechanism for separating the communication antenna of a lunar regolith penetrator provided by the present invention features staggered positioning rings on the main body and the locking ring. Specifically, a connecting line connects the main body positioning ring and the locking ring positioning ring in a zigzag pattern, maximizing the number of connection lines, fully securing the connection between the main body and the locking ring, and ensuring connection stability.

[0019] 4.

The connecting ring 12 is arranged between the first fixing ring 11 and the second fixing ring 13, and the connecting ring 12 is arranged obliquely with the first fixing ring 11 and the second fixing ring 13.

[0045] In some optional embodiments, the stretchable release mechanism for separating the lunar soil penetration projectile communication antenna further includes a support ring 6 and a support seat 7. The support ring 6 is embedded in the first fixing ring 11. The support seat 7 is arranged in the connecting ring 12 and the second fixing ring 13, and the support seat 7 is connected with the support ring 6.
