Air-drop fire extinguishing bomb empennage device

Abstract

The invention discloses an air-drop fire extinguishing bomb empennage device, and belongs to the field of fire extinguishing bombs. The large-wing-surface and large-wingspan folding type empennage structure is adopted, and the device comprises an empennage body, a fixing block, an upper wing surface, a positioning cushion block, a spring hinge, a lower wing surface and a plug screw. The wing surfaces are formed by stamping with a simple process, and the upper wing surface and the lower wing surface are connected through the spring hinge in a riveting mode, so that the folding function is achieved. The wing surfaces are fixedly connected to the empennage body through the fixing block and the plug screw, and the positioning of the upper wing surface during unfolding is realized through the positioning cushion block. In order to enable a bomb body to fall vertically, the wing surfaces adopt a 0-degree mounting angle. Compared with an integrated empennage, the stacked empennage structure and the riveting process are adopted, so that the structure is simple and reliable, and the machining process cost is low.

Description

technical field [0001] The invention relates to an air-dropped fire extinguishing bomb tail device, which belongs to the field of fire extinguishing bombs. Background technique [0002] At present, due to the frequent occurrence of forest fires and the rapid development of the fire, many uncertain dangers have been brought to the fire fighting and rescue work. Unmanned aerial vehicles drop fire extinguishing bombs, which can remotely control fire extinguishing points and avoid casualties. It is a new product in the field of fire prevention. Existing fire extinguishing bomb adopts fixed empennage or folding empennage. Due to the limitation of assembly space, the fixed tail cannot increase the wingspan. Folding the empennage can increase the wingspan, but the folding empennage must have a folding mechanism. The airfoil connection of the existing folding empennage is designed with an opening and locking mechanism, and the airfoil is connected through a rotating shaft, a tors...
