Problems solved by technology

[0005] However, the existing self-expanding emergency positioning devices mostly use similar "water contact separation devices" to separate the positioning device from the aircraft body. In the high-speed flight state and various water-rich environments (when the aircraft passes through rain clouds or in rainy and snowy weather), it will not fall off, and it must complete effective separation in the triggered state, so the reliability of the equipment is often not high, so it cannot be applied In the aviation industry, which has extremely high requirements for equipment safety and reliability; and there will also be situations where it cannot float to the sea after separation. For example, due to the change of flight attitude during the plane crash, the positioning device is located at the lower end of the plane after the crash , its floating is affected by the aircraft body and wreckage, and cannot complete the established positioning target

Embodiment Construction

[0025] Further illustrate installation and application of the present invention below in conjunction with accompanying drawing:

[0026] Such as Figure 1 ~ Figure 2 As shown, an airborne ejection floating emergency positioning device includes an installation section 10, which is installed on the aircraft through an outstretched installation arm; the water sensor 1 is fixed on the outside of the installation section 10, and the parameters are preset to ensure its Correctly trigger after entering the water surface; the transceiver 8 can transmit beacons, GPS positioning signals and / or flashing light position indication signals, and search for response signals; the working battery 7 is connected to the transceiver 8, enough to supply the transceiver 8 to work normally for many days the power demand; the bottom cover 6 is surrounded by the working battery 7, and its protection and sealing function prevent the working battery 7 from being affected by extrusion deformation and mois...

Abstract

The invention provides an onboard catapulting floating emergency positioning device. The device comprises an installation section, a water sensor, a transceiver and a working battery. The device is characterized by further comprising a catapulting component which comprises a starter, a heat battery, a compression spring and an unlocking component. Installation and separation of the emergency positioning device can be conducted separately, so that equipment reliability is ensured; moreover, the emergency positioning device can be catapulted out of an airframe first when encountering water, and it is ensured that the emergency positioning device floats up to the water surface smoothly and sends out a positioning rescue signal automatically to take the preemptive opportunity for search and rescue work.

Description

technical field [0001] The invention belongs to the field of lifesaving devices and relates to an emergency positioning device, in particular to an airborne ejection floating emergency positioning device. Background technique [0002] With the development of the air transport industry, airplanes are an important means of transportation. In order to ensure the safety of passengers and cargo, the safety requirements during the flight are more stringent. However, due to various unexpected situations that may be encountered during the flight , flight accidents are still unavoidable. Therefore, the rescue work after the plane crash is particularly important. The emergency positioning equipment is used to provide the location of the plane crash and provide accurate information for search and rescue work. In particular, compared with a land crash, an aircraft crash at sea is more difficult to search and rescue, so more stringent requirements are put forward for emergency positioni...
