Embodiment Construction

[0018] The specific implementation process of the present invention will be further described below in conjunction with the accompanying drawings:

[0019] Such as figure 1 As shown, the present invention consists of detonating element 8, main charge 9, tail cap 10, piston 11, piston rod 12, sleeve 13, lock nut 14, first shear pin 15, steel ball 16, lock block 17, shell Body 18, lock bar 19, second shear pin 20 and so on. The lock nut 14 is connected with the first connection object, and the lock bar 19 is connected with the second connection object. The piston 11, the piston rod 12, the steel ball 16 and the second shear pin 20 constitute the inner actuator, and the sleeve 13, the first shear pin 15, the steel ball 16 and the lock block 17 constitute the outer actuator.

[0020] The tail cover 10 separates the inner actuator from the outer actuator. The inner actuator is located in the cavity inside the tail cover 10 , and the outer actuator is located in the cavity formed ...

Abstract

A connection and separation device for spacecraft, which is composed of an initiating element, an inner actuator, an outer actuator, etc., and is screwed together with the first connection object through a lock nut arranged on the casing, and is screwed with the second connection object through a lock rod. connected together, so as to realize the reliable connection of the first and second connection objects. When separating, the high-pressure gas generated after the detonating element is detonated drives the movement of the inner and outer actuators respectively, and then completes the unlocking and separation, and realizes the ejection of the second connection object. The device of the present invention is simple in structure and easy to use. As long as one of the inner and outer actuators acts, the unlocking and separation can be completed. Even if one of the actuators fails, the separation will not fail, so it has the advantage of high reliability. .

Description

technical field [0001] The invention relates to a connection and separation device for space vehicle compartments or parts. Background technique [0002] During the launch and in-orbit flight of the spacecraft, reliable connections are required between the spacecraft and the launch vehicle, between the spacecraft body and components, and between the cabin sections. The assembly that requires separation is unlocked and separated according to a predetermined procedure to ensure that the flight The successful completion of the task. Usually, the connection and separation between the spacecraft and the launch vehicle, between the spacecraft body and its components, and between the cabin sections are realized by means of connection and separation devices. [0003] The connection and separation device is generally composed of connection and unlocking parts, separation parts, etc., and has the functions of connection, unlocking and separation. The connection function refers to co...
