DETAILED DESCRIPTION
[0025] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings:
[0026] Figure 1 As shown, the emergency float 10 is a spherical structure, and the emergency float hull 3 wraps it therein, and the float is connected to the mounting seat 9 through a float connecting belt 11 provided on the emergency float 10 .
[0027] Figure 2 As shown, Figure 1 The partially enlarged view shows that the connecting piece 12 is a U-shaped structure, the root of which is installed on the connecting seat 9, and the opening is riveted to the emergency buoy cabin 3. The connecting piece 12 plays a bridge transition role to achieve the fixed connection between the mounting seat 9 and the emergency buoy cabin 3.
[0028] Figure 3 As shown, the four groups of buoy connection belts 11 are installed with the four groups of interfaces of the mounting seat 9 to fix the emergency buoy 10 on the mounting seat 9. The emergency buoy 10 is provided with an air inlet valve 17, and the air inlet pipe 1 is connected to the air inlet valve 17. During emergency inflation, gas enters the emergency buoy 10 through the air inlet pipe 1 and the air inlet valve 17.
[0029] Figure 4As shown, the mounting seat 9 is a "well"-shaped structure, and the protruding 8 claws form 4 groups of mounting holes, in which fixing screws 13 are installed, and the fixing screws are locked by fixing screws 14 after passing through the mounting holes; two groups of connecting rod mounting holes are arranged on the mounting seat 9, and the connecting rod 15 is assembled in the corresponding hole position of the mounting seat 9 by interference fit; the root of the connecting piece 12 is installed on the connecting rod 15, and the opening is riveted to the emergency buoy cabin 3 by fixing rivets 16.
[0030] The mounting seat 9 is a stable structure in a “△” shape or other shapes.
[0031] Figure 5 and Figure 6 As shown, the upper skin 2 and the lower skin 8 are respectively fixed on the emergency buoy hull 3 by encapsulated rivets 6, and the upper skin 2 and the lower skin 8 are connected, constrained and fixed by a fixed rope 4 and a Velcro tape 5. The installation holes of the mounting seat 9 can be seen by opening the cover sheet 7, so that installation and removal can be realized.
[0032] Working principle:
[0033] The connecting rod 15 is assembled on the mounting seat 9. After the connecting piece 12 is assembled with the connecting rod 15, the connecting piece 12 is mounted and fixed on the emergency buoy compartment 3 by the fixing rivet 16, so as to realize the fixed connection between the mounting seat 9 and the emergency buoy compartment 3. The emergency buoy connecting belt 11 is an annular structure, the screw rod 13 passes through the corresponding hole position on the mounting seat 9 and the ring of the connecting belt 11, and the end of the fixing screw rod 13 passes through the hole of the mounting seat 9 and is locked with the fixing screw 14.
[0034] After the emergency buoy 10 and the mounting seat 9 are assembled, the emergency buoy 10 is vacuumed and folded in the emergency buoy cabin, and the lower skin 8 and the upper skin 2 are assembled on the hatch cover by sealing rivets, and then the fixed rope 4 and the Velcro strap 5 are applied between the upper and lower skins to achieve the sealing of the emergency buoy 10. The interface cover 7 is glued to the notch of the lower skin. When installing the emergency buoy assembly, the cover 7 is opened and the installation bolts are passed through the coaxial holes of the mounting seat and the U-shaped groove on the machine to achieve rapid installation.
[0035] When the emergency float 10 is working in an emergency, high-pressure gas enters the float through the air inlet pipe 1 and the air inlet valve 17 on the float. The float is quickly formed and then floats. The load during floating is transmitted to the mounting seat 9 through the connecting belt 11 and the screw 13, thereby transmitting the buoyancy to the helicopter to achieve floating.
[0036] The above scheme is only a preferred embodiment of the present invention and cannot be used to limit the scope of rights of the present invention. Equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
