Embodiment 1

[0059] Specifically, the embodiment of the present invention provides a separation device, and the separation device includes: a locking bar 104, an elastic member 105, a fixing seat 106, a locking handle 103 and a rocker arm 101; the locking bar 104 passes through the first separating body and the second Separator; between the locking bar 104 and the first separating body, an elastic member 105 in a compressed state is provided, or between the locking bar 104 and the second separating body, an elastic member 105 in a stretched state is provided; the fixing seat 106 Fixed with the second separating body; the rocker arm 101 is hinged with the fixed seat 106; the middle part of the lock handle 103 is hinged with the fixed seat 106, and the first end of the lock handle 103 and the lock bar 104 form a first position-limiting structure, and the lock handle 103 The second end and one end of the swing arm 101 form a second limit structure; the first limit structure can prevent the loc...

Embodiment 2

[0081] The first separating body and the second separating body usually have a joint like a flange, and the locking rod 104 can pass over the first separating body and the second separating body from the outside of the joint. According to the structure of Example 1, the embodiment of the present invention is further improved, making it more suitable for setting the first separation body and the second separation body with a flange structure at the joint. It should be noted that, in the embodiment of the present invention , the shape and structure of some parts of Embodiment 1 are improved, so that the improved parts have other functions and advantages in addition to the functions and advantages in Embodiment 1, as follows:

[0082] like Figure 5 to Figure 7 As shown, the embodiment of the present invention provides a separation device based on a rocker link. The separation device includes: a fixed seat 106, a lock handle 103, a mounting plate 109, an elastic member 105, a roc...

Embodiment 3

[0095] like Figure 11 , Figure 12 As shown, the embodiment of the present invention also provides a mechanical separation system, the mechanical separation system includes a mechanical separation unit and an unlocker; the mechanical separation unit is the separation device of embodiment 2; there are multiple mechanical separation units, and all mechanical separation The connecting rod 102 of the unit can be connected coaxially in turn, or the connecting rod 102 of the mechanical separation unit is a coaxial integral structure; the unlocker is a telescopic structure, and the telescopic end of the unlocker is connected with the connecting rod 102 of the mechanical separation unit, and It can drive the connecting rod 102 to move in translation. In the embodiment of the present invention, a plurality of separation devices are connected in series and controlled by the same connecting rod 102, realizing the start control of all separation devices by a single start source, with si...

Abstract

The invention relates to a separation device based on a rocker arm link and a mechanical separation system, and belongs to the technical field of aerospace. The problems that an existing separation mechanism uses an initiating explosive device to complete separation and therefore is high in cost, poor in safety and incapable of being reused are solved. The separation device comprises a fixing base, a lock handle, a mounting plate, an elastic piece, a rocker arm, a connecting rod and an elastic block, wherein the fixing base is fixedly connected with a first separating body, and the mounting plate is fixedly connected with a second separating body; the lock handle is hinged to the fixing base, the rocker arm is hinged to the fixing base, the elastic block is hinged to the rocker arm, and the connecting rod is hinged to the rocker arm; the elastic piece is used for connecting the lock handle and the fixing base, the elastic block and the lock handle form a limiting structure, and the elastic piece is made to be in a stretched state; and a hinge shaft between the lock handle and the fixing base and a hinge shaft between the elastic block and the rocker arm are both parallel to a firstdirection, and a hinge shaft between the rocker arm and the fixing base and a hinge shaft between the connecting rod and the rocker arm are both parallel to a second direction. The separation devicedoes not need the initiating explosive device, can realize bidirectional unlocking and separation, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a separation device and a mechanical separation system based on a rocker link. Background technique [0002] The function of the separation device is to reliably connect the two parts that need to be separated before the separation action is performed. When the separation command is received, it can be quickly unlocked. Some devices can also provide separation power when unlocked. Typical applications are rectification Cover separation, separation between stages of launch vehicle, separation of satellite and rocket, etc. [0003] According to whether the separation point is continuous, it can be divided into point separation and linear separation. [0004] The separation points of point separation are distributed in multiple points on the separation surface of the two bodies, mainly including explosive bolts, etc. Generally, the load capacity of a single point is low, so it i...
