Problems solved by technology

In the prior art, the patent CN106402547 A discloses a low-temperature self-sealing connector with low reliability of zero-second shedding
The locking mechanism of the connector mostly adopts the claw type. Before the rocket takes off, the cylinder needs to drive the claw to unlock and fall off in advance. If the launch is delayed or canceled, the connector needs to be re-docked manually. It is not suitable for unattended and zero-second drop-off occasions

Abstract

The invention provides an eccentric locking mechanism applied to a zero-second falling-off connector and the connector. The eccentric locking mechanism comprises an eccentric wheel shaft; eccentric wheels symmetrically arranged at two ends of the eccentric wheel shaft; and two length-adjustable connecting rods symmetrically arranged on the eccentric wheel shaft; wherein after the connector body is in butt joint with a rocket valve, the length of the connecting rod is adjusted, so that the eccentric wheel is tightly pressed on the rocket valve. According to the eccentric locking mechanism, the connection is reliable, zero-second falling is reliable, the failure rate is reduced, secondary butt joint is avoided, and guarantee is provided for personal and equipment safety.

Description

technical field [0001] The invention relates to the related technical field of launch vehicle filling equipment, and in particular to an eccentric locking mechanism and a zero-second drop-off connector applied to the filling or release of liquid nitrogen, liquid oxygen, and liquid methane. Background technique [0002] The cryogenic liquid connector is used in the liquid rocket cryogenic filling system. The connector must not only ensure that it is connected to the filling port without leakage during the filling or leaking stage, but also ensure that the rocket can be unlocked and released after it takes off to a certain height. The final self-sealing ensures reliable connection, reliable sealing, and reliable zero-second shedding. In the prior art, patent CN106402547 A discloses a low-temperature self-sealing connector with low reliability of zero-second shedding. The locking mechanism of the connector mostly adopts the claw type. Before the rocket takes off, the cylinder ...
