A float encapsulation structure for short-wing helicopters

Abstract

This utility model discloses a pontoon sealing structure for helicopters with short wings, including a fixing plate. A pontoon body is mounted at the bottom of the fixing plate, and nylon sleeves are movably connected to both sides of the pontoon body. The centerline of the fixing plate and the centerline of the pontoon body are on the same vertical plane. This pontoon sealing structure for helicopters with short wings utilizes mounting plates. During installation, the fixing rings at the top of the mounting plates on both sides of the pontoon body are inserted into through slots, and the mounting plates are fitted against the bottom of the fixing plate. Then, the ejector spring inside the fixing pontoon can push out the connecting rods via connecting pieces, allowing the connecting rods to insert into the fixing rings. The fixing rings then secure the bottom mounting plate and the pontoon body. For disassembly, pressing the connecting rods at both ends disengages them from the fixing rings, allowing the pontoon body to be removed. This solves the problem of slow assembly and disassembly.

[0002] A short-wing helicopter is a type of helicopter with short wings on both sides of the fuselage. The short wings can effectively improve the helicopter's lift and load-bearing capacity. When performing some special missions, short-wing helicopters will be equipped with floats to enable forced landings and floating on the water. The floats need to be fixed with a special encapsulation structure during installation.

[0003] However, the encapsulation structure currently used for pontoon installation on short-wing helicopters still has some defects in use. When installation is required, the installation operation is difficult, resulting in a long time required for pontoon assembly and disassembly.

[0004] A novel float encapsulation structure for short-wing helicopters is proposed to address the aforementioned problems. Utility Model Content

[0014] (1) By setting up an installation plate, a fixing collar, a connecting rod, a through groove, an ejector spring, a fixing cylinder and a connecting piece, when installing this structure, the fixing collars on the top of the installation plates on both sides of the top of the float body are inserted into the through groove, and the installation plate is attached to the bottom of the fixing plate. Then the ejector spring inside the fixing cylinder can eject the connecting rod through the connecting piece, so that the connecting rod is inserted into the inside of the fixing collar and can be fixed to the bottom installation plate and the float body through the fixing collar. When disassembling, press the connecting rods at both ends to make them disengage from the inside of the fixing collar, and the float body can be disassembled. This achieves quick assembly and disassembly of the structure.

[0015] (2) By setting up an installation plate, nylon sleeve, connecting strap, connecting plate, fixing tube, connecting spring, fixing pin, connecting slot and positioning slot, the structure attaches the float body together with the outer nylon sleeve to the bottom of the installation plate after installation.

Connecting cables are wound inside the metal rings outside the nylon bags. The connecting cables can connect and fix the two sets of nylon bags to ensure the stability of the float body and achieve effective protection of the float body. Attached Figure Description
