Technical Field
The invention belongs to the technical field of shipboard aircraft warship surface guarantee, and particularly relates to a personnel safety protection device suitable for a hidden ship.
Background
Ships such as a destroyer and a guard ship are generally provided with a helicopter taking-off and landing platform at the stern part of the ship for taking off, landing, parking and guaranteeing the carrier-borne helicopters. The influence of external factors such as longitudinal and transverse shaking motion of ships and warships and sea wind is considered, and if no effective measures are taken, a naval crew carries out helicopter guarantee operation on a take-off and landing platform, and the risk of falling into the sea exists.
At present, a safety net is usually arranged around a take-off and landing platform to prevent operators on the take-off and landing platform from falling into the sea. When the personnel are ensured to the helicopter, the safety net is erected to ensure the safety of the personnel; when the helicopter takes off or lands, the safety net falls down, so that the safety net is prevented from interfering with the helicopter, and the taking-off and landing safety of the helicopter is ensured. However, the existing safety net protection mode has the following defects:
(1) is not beneficial to the stealth design of the ship. The safety net usually adopts outside steel pipe frame, and the mode that inside wire rope was woven easily reflects radar wave, under the present condition of more and more paying attention to the stealthy design of naval vessel, does not conform to the trend of technical development.
(2) The safety net is vertically placed by manual operation, and the labor intensity is high. In order to ensure the reliable retraction of the safety net, a worm and gear driving mode is mostly adopted at present, and the safety net is driven to erect or fall down by manually rotating a handle. As the single safety net reaches more than one hundred kilograms, a great deal of manpower and time are consumed for collecting and releasing the twenty-three safety nets of the whole lifting platform.
(3) The safety net is easy to rust, and the later maintenance workload is large. Influenced by marine environment, the safety net piece and the worm and gear mechanism are easy to rust, but because the safety net is arranged close to the side, personnel need to carry out open-air maintenance on the stern of the ship, the operation and maintenance are carried out, and the workload is large.

The inclination angles of the outer walls of the hidden enclosure in 4 directions are 11-15 degrees, vertical intersecting planes are avoided, and wave absorbing materials are coated to reduce radar wave reflection.
The hidden enclosure is a rectangular area enclosed by four wall plates at the front, the back, the left and the right. The surface of the outer wall of the enclosure is flat, a certain inclination angle is formed between the surface of the outer wall of the enclosure and the vertical direction, and the outer surface of the enclosure is coated with a radar wave absorbing material, so that the reflection area of radar waves can be greatly reduced, and the stealth performance of equipment is improved.
The length and the width of the protective panel are matched with the hidden surrounding threshold, the thickness of the protective panel is 5mm, the protective panel is made of composite materials, and the back of the protective panel is reinforced. The protective panel can rotate around the rotating shaft to realize two states of putting down and rising. Be equipped with the handrail on the panel, high distance pivot center is about 1000mm, and wooden or combined material can be selected to the handrail material, and when the panel rose, the platform operation personnel of taking off and land can support the handrail, improved the operation security of personnel on the platform of taking off and land helicopter.
The driving mechanism consists of a miniaturized hydraulic power unit, a hydraulic cylinder and a corresponding pipeline, wherein the hydraulic power unit drives high-pressure hydraulic oil into the hydraulic cylinder to extend the hydraulic cylinder and drive the protective panel to rise; when the hydraulic power unit stops outputting hydraulic oil and opens the oil return valve, the protective panel compresses the hydraulic cylinder by utilizing the self gravity to enable the hydraulic oil to flow back to the hydraulic oil tank, and the protective panel is closed accordingly. The hydraulic power unit is required to meet the requirements of the open-air use environment of the ship, and a safety protection cover is arranged outside the hydraulic power unit to avoid injury to personnel.
The use process comprises the following steps: when a ship sails, the safety protection device is put down, and the radar reflection area of the ship is reduced by means of the stealth design. Before the helicopter takes off and lands, the safety protection device is still in a putting down state, improves the airflow field of a take-off and landing platform of the helicopter, avoids spatial interference in the take-off and landing operation of the helicopter, can limit the take-off and landing of the helicopter in an anti-skidding way when the helicopter takes off and lands, and improves the take-off and landing safety of the helicopter. When the helicopter falls, the protection device rises, and the personnel on the lifting platform take place, so that the protection device can safely protect the personnel operating on the lifting platform of the helicopter, avoid the personnel falling and reduce the wind load born by deck operating personnel; in addition, this protector rises the back, and the light of protector back installation can be opened, provides the illumination for deck take off and land guarantee operation night. And an operator can pull out terminal hoses and cables of the oil filling, power supply, gas supply, hydraulic pressure, inertial navigation alignment and other guarantee equipment from a deck opening in the hidden enclosure as required to carry out aviation guarantee operation.
The device comprises a hidden enclosure, a protective panel and a driving mechanism, wherein the protective panel is laid down when the helicopter takes off and lands and is integrated with the hidden enclosure, so that the reflection area of radar waves is reduced; when the personnel on the platform of taking off and landing begin the operation, protective panel rises to certain inclination, can provide a safety barrier for the personnel of the platform of taking off and landing on, can reduce radar wave reflection simultaneously as far as possible. The personnel protection measure with better radar stealth performance, higher automation degree and more convenient installation can be provided for the aircraft carrier.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
