[0029] The utility model discloses an ejection recovery device. When ejection recovery is required, the ejection assembly in the ejection chamber 1 is started, and the recovery chamber 2 is ejected and separated from the ejection chamber 1, so as to realize automatic ejection separation; when started, the pop-up slider 3 slides, driving the recovery chamber 2 to pop out toward the end away from the ejection chamber 1, and after popping out, the pop-up slider 3 is separated from the recovery chamber 2, so as to realize recovery; when recovery is not started, the start rod 4 is clamped and fixed, and the start spring 5 is compressed, so that the pop-up slider 3 is located at the bottom end of the ejection chamber 1, and after starting, the start rod 4 is no longer stuck, and the start spring 5 rebounds, driving the pop-up slider 3 and the ejection chamber 1 to pop out, so as to realize automatic separation. The utility model has a simple structure, is easy to use, and has a rapid pop-up response. At the same time, the entire device is a mechanical structure, which is simple to maintain and has high reliability. The entire pop-up structure will not be damaged during pop-up separation, which is convenient for subsequent reuse and reduces the use cost of the entire device.

[0030] Furthermore, a sliding bearing 24 adapted to the starting rod is installed at the bottom end of the ejection chamber 1 to support the starting rod 4 and reduce sliding resistance.

[0031] Further optimization scheme, the ejection solenoid valve 6 is fixedly installed at the bottom end of the ejection chamber 1, and the release rod 7 is movably arranged on the ejection solenoid valve 6, and the release rod 7 is arranged and connected with the release hole 8 arranged on the starting rod 4. The bottom end of the ejection chamber 1 of this embodiment is provided with a mounting block 25, and the ejection solenoid valve 6 is fixedly installed on the mounting block 25. When the device is not started, the release rod 7 on the ejection solenoid valve 6 extends into the release hole 8 of the starting rod 4 and is stuck, so as to prevent the starting rod 4 from moving and causing an accidental ejection; when the recovery device is started, the ejection solenoid valve 6 is started, driving the release rod 7 to be recovered, so that the release rod 7 is separated from the release hole 8, the starting rod 4 loses the external force, loses the locking of the ejection slider 3, and the starting spring 5 resets after losing the external force, pushing the ejection slider 3 to drive the recovery chamber 2 to be ejected from the ejection chamber 1 to achieve separation.

[0032] Further optimization scheme, the recovery chamber 2 includes a conical fairing 9, the bottom end of the fairing 9 is movably connected with a parachute chamber 10, the bottom end of the parachute chamber 10 extends into the ejection chamber 1 and is movably sleeved on the pop-up slider 3. The fairing 9 is conical, which is convenient for penetrating the air and reducing air resistance; the parachute chamber 10 is mounted on the bottom end of the fairing 9, and a deceleration parachute is installed inside the parachute chamber for deceleration; at the same time, the end of the parachute chamber 10 away from the fairing 9 is sleeved and connected to the pop-up slider 3, and when the pop-up slider 3 is ejected from the chamber by the activation spring 5, the parachute chamber 10 is separated from the pop-up slider 3, so that the recovery chamber 2 is separated from the ejection chamber 1.

[0033] Further optimization scheme, the parachute chamber 10 includes a plurality of protective sheets 11, and the two contact surfaces of two adjacent protective sheets 11 are respectively provided with a plurality of first positioning blocks 12 and a plurality of first positioning grooves 13, and the first positioning grooves 13 and the first positioning blocks 12 are correspondingly arranged and fixed by clamping. The parachute chamber 10 of this embodiment is composed of two symmetrically arranged protective sheets 11, each protective sheet 11 is arranged in a semicircular shape; the two protective sheets 11 are positioned and fixed by the first positioning blocks 12 and the first positioning grooves 13; at the same time, the end of the parachute chamber 10 facing the ejection chamber 1 is conical, and when the parachute chamber 10 is combined with the ejection chamber 1, the end of the ejection chamber 1 presses and fixes the two protective sheets 11 together; and when the parachute chamber 10 is ejected from the ejection chamber, the two protective sheets 11 are separated by the deceleration parachute, which facilitates the ejection of the deceleration parachute.

[0034] In a further optimized solution, a plurality of second positioning grooves 14 are arranged in an annular manner on the outer wall of the pop-up slider 3, and a plurality of second positioning blocks 15 adapted to the second positioning grooves 14 are arranged on the inner wall of the protective sheet 11, and the second positioning blocks 15 are clamped and fixed in the second positioning grooves 14. When the two protective sheets 11 are assembled, the second positioning blocks 15 on the protective sheets 11 are clamped into the second positioning grooves 14, and at the same time, the two protective sheets 11 are pressed together in combination with the structure of the ejection chamber 1, and then the hoop is fixed on the outside of the pop-up slider 3. When ejecting, the pop-up slider 3 drives the ejection chamber 1 to eject, and after the two protective sheets 11 are separated by the deceleration parachute, the second positioning blocks 15 are separated from the second positioning grooves 14, so that the parachute chamber 10 and the ejection chamber 1 are separated.

[0035] Furthermore, the ejection chamber 1 of the present embodiment is also composed of two half pieces, which are fixedly assembled by a structure similar to the first positioning groove 13 and the first positioning block 12 .

[0036] In a further optimized solution, a plurality of guide blocks 16 are fixedly connected to the side wall of the pop-up slider 3, and a guide groove 17 matching the guide block 16 is provided on the inner wall of the ejection chamber 1, and the guide block 16 is slidably connected in the guide groove 17. After the two halves of the ejection chamber 1 are assembled, a plurality of guide grooves 17 are formed, and the guide block 16 fixed to the outside of the pop-up slider 3 is slidably connected in the guide groove 17, so as to realize the stable position limiting of the pop-up slider 3, and at the same time, the maximum moving position of the pop-up slider 3 can be limited to prevent it from slipping out, so as to facilitate the subsequent continued use.

[0037] In a further optimized solution, the end of the guide groove 17 away from the start spring 5 is fixedly connected to the limit detection block 18, and a contact block 19 is arranged on the limit detection block 18.

The limit detection block 18 is installed at the end of the guide groove 17. When the pop-up slider 3 pops out, the guide block 16 moves to the end of the guide groove 17, so that the guide block 16 pushes the elastic sheet 20 to move toward the contact block 19, so that the elastic sheet 20 and the contact block 19 move, resulting in electricity between them, triggering the limit switch and returning the signal.

[0038] In a further optimized solution, a connecting ring 21 is fixedly connected to the bottom end of the fairing 9, and a connecting groove 22 is formed in an annular manner on the connecting ring 21. A connecting strip 23 matching the connecting groove 22 is fixedly connected to the inside of the protective sheet 11, and the connecting strip 23 is clamped in the connecting groove 22. When the protective sheet 11 is assembled, the connecting strip 23 on the inner wall of the protective sheet 11 is embedded and clamped in the connecting groove 22, so that the two protective sheets 11 are clamped on the connecting ring 21 at the bottom end of the fairing 9, so that the fairing 9 and the parachute compartment 10 form a recovery compartment 2.
