[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Figure 1 , Figure 2 and Figure 3 The fast ejection device for marine lifesaving equipment shown in the figure comprises an external frame installed on the outer wall of the hull and a life buoy arranged inside the external frame, the external frame comprises a lateral support frame 1 bolted to the outer wall of the hull, a flip stretching frame 2 movably assembled on the lateral support frame 1, an inclined material guiding frame 3 welded and fixed to the outer wall of the hull, and a side feeding frame 4 fixed inside the outer wall of the hull, an electric-controlled ejection mechanism 5 is assembled on the inner top surface of the end of the flip stretching frame 2 away from the side feeding frame 4, and a bottom-mounted material guiding mechanism 6 is movably assembled on the inner bottom surface of the inclined material guiding frame 3.

[0027] In order to cooperate with the electric-controlled projectile, the electric-controlled projectile mechanism 5 includes a driving motor 51 fixed to one side of the top surface of the flip and stretching frame 2, a flip adjustment arm 52 axially fixed on the lateral driving shaft of the driving motor 51, an electric-controlled limit arm 53 movably installed at the bottom end of the flip adjustment arm 52, an inner flip driving arm 54 movable inside the flip and stretching frame 2, an outer squeezing arm 55 fixed on the outer side wall of the inner flip driving arm 54, a lateral limit seat 56 fixed on the side wall of the flip and stretching frame 2, an arc-shaped guide rod 57 installed on the lateral limit seat 56, and an squeezing spring 58 sleeved on the arc-shaped guide rod 57.

[0028] The driving motor 51 is the prior art, which drives the flip adjusting arm 52 to flip, thereby squeezing the inner flip driving arm 54 through the electric control limit arm 53, and then the outer squeezing arm 55 on the inner flip driving arm 54 squeezes the squeezing spring 58. When the electric control limit arm 53 squeezes the inner flip driving arm 54 to flip to the set position, the electric control limit arm 53 flips outward, thereby losing the limit on the inner flip driving arm 54, and then the squeezing spring 58 will squeeze the outer squeezing arm 55 along the arc guide rod 57, driving the inner flip driving arm 54 to flip in the opposite direction, thereby throwing the lifebuoy out.

[0029] In order to cooperate with the bottom conveying, the bottom-mounted material guiding mechanism 6 includes a driven support wheel 61 movably mounted on the inner bottom surface of the inclined material guiding frame 3, a flexible conveyor belt 62 sleeved on the driven support wheel 61 and an arc-shaped material discharging seat 63 fixed on the flexible conveyor belt 62.

[0030] In order to cooperate with the flipping adjustment, the flipping and stretching frame 2 includes an arc-shaped flipping frame 21 movably assembled on the lateral support frame 1 and an electric control support rod 22 movably installed between the lateral support frame 1 and the arc-shaped flipping frame 21 .

[0031] The electric control support rod 22 is a prior art, and controls the arc-shaped flip frame 21 to flip by extending and retracting.

[0032] In order to reduce the excessive impact force on the arc-shaped turning frame 21 caused by the life buoy rolling down, an arc-shaped shock absorbing plate 23 is elastically mounted on the inner arc surface of the arc-shaped turning frame 21 corresponding to the position of the feeding port of the side feeding frame 4.

[0033] In order to improve the driving performance, two transverse control arms 59 bent to one side are provided on the side wall of the inner flip driving arm 54 .

[0034] In order to cooperate with external movable assembly and rotation adjustment, the bottom end of the flip adjustment arm 52 has a bottom movable frame protruding downward, and the electric control limit arm 53 includes a flip limit arm 531 movably installed inside the bottom movable frame through a lateral rotating shaft and an external separation support rod 532 movably connected between the flip adjustment arm 52 and the flip limit arm 531.

[0035] The external separation support rod 532 is a prior art, which drives the flip limit arm 531 to flip so that the inner flip driving arm 54 loses its limit.

[0036] In order to cover and close the entire shooting device when not in use, a flip-up external cover shell 7 is movably mounted on the outer wall of the hull and outside the external frame.

[0037] The flip-type external cover 7 is composed of a flip cover 71 movably mounted on the outside of the hull and an external expansion and contraction strut 72 installed between the flip cover 71 and the outer side of the hull, wherein the external expansion and contraction strut 72 is a prior art and controls the flipping of the flip cover 71 by telescoping.

[0038] In order to cooperate with internal loading, the side feed frame 4 includes an internal loading frame 41 installed inside the hull, a transverse material guide frame 42 installed at the inner end of the internal loading frame 41, and a built-in material guide mechanism 43 installed on the inner bottom surface of the transverse material guide frame 42.

[0039] A chamber is set up inside the hull, and then the side feeding frame 4 is installed inside the chamber, a lifebuoy is set inside the chamber, and then the lifebuoy inside the chamber is translated to the inside of the internal loading frame 41 by the built-in material guiding mechanism 43 on the inner bottom surface of the horizontal material guiding frame 42, and then rolled into the unfolded flip stretching frame 2, and then the lifebuoy is moved to the position of the electric-controlled ejection mechanism 5 by the bottom-mounted material guiding mechanism 6 on the inner bottom surface of the inclined material guiding frame 3, and the lifebuoy is ejected by the electric-controlled ejection mechanism 5.

[0040] In order to cooperate with the synchronous drive, the bottom-mounted material guiding mechanism 6 and the built-in material guiding mechanism 43 are synchronously driven through the linkage shaft 8 on the inner bottom surface of the internal loading frame 41.

[0041] The structures of the bottom-mounted material guiding mechanism 6 and the built-in material guiding mechanism 43 are basically the same. The only difference is that the innermost wheel group of the built-in material guiding mechanism 43 is changed to the main driving wheel of the prior art, and then the driven wheel on the other side and the driven supporting wheel 61 on one side of the bottom-mounted material guiding mechanism 6 are synchronously transmitted through the linkage shaft 8. The synchronous transmission method is to use the synchronous gears on both sides of the linkage shaft 8 to mesh with the driven wheel on one side of the built-in material guiding mechanism 43 and the connecting gears on the driven supporting wheel 61 on one side of the bottom-mounted material guiding mechanism 6, so as to achieve the purpose of synchronous transmission.

[0042] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
