Detailed Description

Reference will now be made in detail to various exemplary embodiments of the invention, the detailed description should not be construed as limiting the invention but as a more detailed description of certain aspects, features and embodiments of the invention.

It will be apparent to those skilled in the art that various modifications and variations can be made in the specific embodiments of the present disclosure without departing from the scope or spirit of the disclosure. Other embodiments will be apparent to those skilled in the art from consideration of the specification. The specification and examples are exemplary only.

Fig. 1 is a structural view of an arrow body connector capture device according to the present invention. In the embodiment shown in the drawings, the capturing means comprises: the frame 2, the front net assembly 3, the door swing structure 4 and the rear net assembly 5. Wherein the frame 2 is used for being fixedly connected with the rocket launching vertical arm and providing a mounting platform for each part of the capturing device. Preferably, the material of the frame 2 is steel Q460, and a thermal protection coating is sprayed on the surface of the frame 2 to protect the frame 2 from being damaged by high temperature. Because the tail flame temperature of the rocket during takeoff is high, a high-temperature resistant material is required to be selected as a main body material of the frame 2, and a heat-proof coating is coated on the surface of the frame 2, so that the frame 2 is further protected from being damaged by the tail flame temperature of the rocket.

As shown in fig. 5, the front net assembly 3 has a first intercepting net 32 and an energy storage device 36, the front net assembly 3 is disposed on the frame 2, and the energy storage device 36 is used for bouncing the first intercepting net 32 to intercept the connector 1 having the pulling structure, and limiting the position of the connector 1. The door swing structure 4 is provided on the frame 2 for guiding the connector 1 into an intercepting space composed of the front net assembly 3 and the rear net assembly 5 by a drawing structure of the connector. In this embodiment, the door swing structure 4 can be pushed open only in one direction, i.e. the direction of the rear net assembly 5, and also the direction in which the connector 1 swings into the capturing device. After the connector 1 and the pulling structure push the door swing structure 4 by means of the own swinging force, once the pushing force disappears, the door swing structure is quickly closed, and the connector 1 and the pulling structure are blocked between the door swing structure 4 and the rear net assembly 5.

The rear net assembly 5 has a second intercepting net 51, and the rear net assembly 5 is disposed on the frame 2 to form an intercepting space with the front net assembly 3 to intercept the connector 1. In this embodiment, the front net assembly 3, the door swing structure 4, and the rear net assembly 5 form a space for limiting the position of the connector 1, and it is ensured that the connector 1 does not touch the arrow body after falling off from the arrow body. When the connector 1 and the pulling structure push the door swing structure 4 by means of their own swinging force, once the pushing force disappears, the door swing structure 4 will be quickly closed, and the connector 1 and the pulling structure will be limited between the front net assembly 3 and the rear net assembly 5.

In a specific implementation manner of this embodiment, the front net assembly 3 further includes: a fixed rod 31, a trigger device 33, a magnetic pin 34 and a limit pin 35. Wherein a fixing bar 31 is fixed to the frame 2, and the fixing bar 31 is used to connect and unfold the first intercepting net 32. The triggering device 33 is disposed on the door swing structure 4, and the triggering device 33 is configured to detect the motion of the door swing structure 4 and trigger the magnetic pin 34 or the limit pin 35 to move after the door swing structure 4 moves to a preset position. As shown in fig. 4, a magnetic pin 34 is provided on the fixing rod 31 at a lower portion of the fixing rod 31, that is, a compressed position or an initial position of the first intercepting net 32. The magnetic pin 34 is electrically connected to the triggering device 33 for restricting the initial position of the first intercepting net 32. The limiting pin 35 is disposed on the fixing rod 31, and is located at the upper portion of the fixing rod 31 (or may be electrically connected to the triggering device 33, and extends out of or retracts into the upper portion of the fixing rod 31 only when the triggering device is actuated) for realizing high-level locking of the first intercepting net 32. In this embodiment, the triggering device 33 is preferably a travel switch. As shown in fig. 3, the travel switch is disposed on the door swing structure 4, and is configured to detect the motion of the door swing structure 4, transmit an electrical signal to the magnetic pin 34 and the limit pin 35, and control the extension and retraction of the magnetic pin 34 and the limit pin 35. The magnetic pin 34 and the stopper pin 35 can simultaneously perform telescopic operation according to an electric signal of the travel switch. For example, when the travel switch on the door swing structure 4 is triggered, the magnetic pin 34 and the stopper pin 35 are simultaneously retracted. When the door swing structure 4 is closed and the travel switch is reset, the magnetic pin 34 and the limit pin 35 simultaneously extend out to limit the first intercepting net 32.

As shown in fig. 6, the magnetic pin 34 is electrically connected to the triggering devices 33, the triggering devices 33 are connected in parallel, and the extension and contraction of the magnetic pin 34 can be controlled after any one of the triggering devices 33 is triggered. The fixed bar 31 on both sides of the first intercepting net 32 has a magnetic pin 34, and both magnetic pins 34 can be controlled by any one of the triggering devices 33. Similarly, the limit pin 35 and the triggering device 33 are also in circuit connection, and since the triggering devices 33 are connected in parallel, the limit pin 35 can be controlled after any one triggering device 33 is triggered. For example, the fixing rods 31 on both sides of the first intercepting net 32 may be provided with a stopper pin 35, and the stopper pins 35 may be controlled by any one of the triggering devices 33.

In a specific embodiment of this embodiment, as shown in fig. 5, the fixing rod 31 is a hollow tube, the energy storage device 36 is disposed inside the fixing rod 31, and a tube wall of the fixing rod 31 has an opening with a certain length along an axial direction, for connecting the first intercepting net 32 with the energy storage device 36. The first intercepting net 32 is connected to the top end of the energy storage device 36, and when the magnetic pin 34 is retracted, the energy storage device is stopped, so that the energy storage device 36 can jack up the first intercepting net 32 under the action of its elastic restoring force. Preferably, the energy storage device 36 may be a spring. In the initial position, the spring is in a compressed state.

In a specific implementation manner of this embodiment, as shown in fig. 2, the door swing structure 4 further includes: the fixed seat 41, the door swing rod 42, the connecting pin 43 and the elastic piece 44. Wherein, fixing base 41 is fixed on frame 2, and fixing base 41 is inside hollow form, and the side has the trompil, and this trompil is used for carrying on the installation of other parts. In addition, the upper and lower ends of the fixing base 41 are provided with pin holes, and the connecting pin 43 is inserted into the pin holes to fixedly connect the components. The door swing link 42 is fixed on the fixing seat 41 through a connecting pin 43, and the rotation angle is within the arc range of the opening on the side of the fixing seat 41. The connecting end of the door swing rod 42 is inserted into the fixing seat 41 from the opening, then the connecting pin shaft 43 is inserted into the pin hole, the door swing rod 42 is limited in radial movement, and the door swing rod 42 can only rotate around the connecting pin shaft 43. The elastic member 44 is fixed in the fixing seat 41 by a connecting pin 43, and is used for providing a swinging force to the door swinging rod 42. The elastic member 44 is disposed at the opening, the elastic member 44 is limited in the opening by the connecting pin 43, one side of the elastic member 44 contacts the fixing seat 41, and the other side contacts the door swing rod 42. The elastic piece 44 applies thrust or does not apply thrust to the door swing rod 42 in the initial state of the door swing rod 42 (the door swing rods 42 on the two sides are in a butt joint state or a closing state), and when the door swing rod 42 is opened in an intercepting space under the thrust action of the traction structure and the connector 1, the elastic piece 44 applies thrust to the door swing rod 42 to enable the door swing rod 42 to be rapidly restored to the initial position, so that the traction structure and the connector 1 can be limited in the intercepting space formed by the front net assembly 3 and the rear net assembly 5. In one embodiment, the elastic member 44 is a V-shaped elastic member fixed on the connecting pin 43, and the V-shaped opening of the elastic member 44 faces outward. One end of the door swing rod 42 is sleeved on the connecting pin shaft 43 and rotates around the connecting pin shaft 43 when being subjected to circumferential force, and the elastic piece 44 is arranged between the door swing rod 42 and the inner wall of the opening of the fixed seat 41 and can apply thrust to the door swing rod 42.

In a specific implementation manner of this embodiment, the rear net assembly 5 further includes: the fixing frame 52 and the second intercepting net 51 are fixed on the fixing frame 52, and the fixing frame 52 is fixedly connected with the frame 2 and the front net assembly 3, so that an intercepting space is formed among the front net assembly 3, the door swing assembly 4 and the rear net assembly 5.

In the specific embodiment of this embodiment, the first blocking net 32 is made of asbestos cloth. The rear net assembly 5 is provided with a second interception net 51, and the material of the second interception net 51 is also asbestos cloth. The asbestos cloth material is high temperature resistant, is not easily influenced by rocket tail flame, and can ensure the normal capture of the connector.

The process of capturing the connector with the pulling structure by the capturing device of the embodiment of the invention is as follows:

after the rocket takes off, the connector 1 is disconnected, the connector 1 swings downwards and pushes the door swing rod 42 to move under the action of the traction structure, after the trigger device 33 is triggered, the magnetic pin 34 and the limiting pin 35 retract, the limiting of the spring is released, and the spring exerts force and drives the first intercepting net 32 to move upwards. When the door swing link 42 loses the pushing force of the connector 1, the door swing link 42 is reset by the elastic member 44. In the resetting process, the triggering device 33 is triggered again, the magnetic pin 34 and the limiting pin 35 extend out, the limiting pin 35 limits and locks the first intercepting net 32 at a high position, the first intercepting net 32 is prevented from falling downwards, and the connector 1 cannot swing back and forth. The first interception net 32 on the front net assembly 3 and the second interception net 51 on the rear net assembly 5 can buffer and damp the connector 1, and intercept the connector 1 between the first interception net 32 and the second interception net 51, thereby achieving the purpose of capturing the connector 1.
