Description

Technical Field

[0001] The invention relates to the technical field of life rafts, in particular to a raft light structure of a life raft for marine rescue. Background Art

[0002] Life rafts are life-saving facilities and equipment equipped on ships for escaping from dangerous areas or evacuating from distressed ships in emergency situations. They can also be used as special equipment for marine rescue. Life rafts are essential for ship life-saving equipment because of their simple structure, convenient maintenance and reliable use. Life rafts are one of the important life-saving equipment necessary for maritime navigation. They have the advantages of small size, light weight, simple structure, easy use, good performance and high cost performance, and play a good role in ensuring safe navigation and operation at sea.

[0003] Life raft lights are lighting devices installed on life rafts, which are generally divided into position lights and illumination lights. Position lights are used as signal indications, for example, through specific flashing patterns to identify the identity, status or intention of the ship, and to communicate effectively with other ships or shore personnel. Illumination lights can provide the lighting required for operations. Existing life rafts usually need to be equipped with lamps, one is to indicate the position of the hull, and the other is to provide lighting for rescue; but the existing life raft lights are basically installed on the hull. When the lights are installed on the hull, their main functions include providing lighting to help the crew carry out various activities at night or in poor visibility. The existing life raft lights have the following disadvantages: First, since the lights are installed on the hull, once the life raft capsizes or disintegrates, the lights may lose their function due to damage to the hull. In an emergency, this may affect the safety of the occupants and the efficiency of search and rescue work. Secondly, if the lights are installed in an improper position, they may be blocked by other parts of the hull, resulting in the light not being able to fully illuminate the surrounding area, or the signal cannot be accurately recognized by distant personnel or search and rescue equipment. This may reduce the actual effectiveness of the light and even lead to misleading in some cases. In addition, the lights on the hull may be affected by natural environmental factors such as waves and wind, and may appear to be shaking or unstable. This may not only affect the effectiveness of the light, but also increase the sense of insecurity of the occupants in an emergency. Therefore, how to design a raft light structure for a life raft floating on the sea for marine rescue is particularly important; in view of this, we propose a raft light structure for a life raft for marine rescue.

[0014] A method for using a raft light structure of a life raft for marine rescue, comprising the following steps:

[0015] S1, release operation;

[0016] First, when the rescue raft light needs to be released, a cylinder is arranged on the bearing plate, a driving shaft is arranged at the output end of the cylinder, a slider is connected to the driving shaft, a movable groove is symmetrically provided on the slider, a rotating rod and a first spring are arranged inside the movable groove, when the cylinder drives the driving shaft and the slider to move, the rotating rod is adapted to the shape of the straight hole and the inclined hole, and the raft light is released under the action of the first spring;

[0017] S2, rescue operation;

[0018] When the raft lamp falls on the sea, since a lampshade is arranged on the top of the lamp body and a trigger assembly is arranged on the bottom of the lamp body, when the trigger assembly falls on the sea, seawater enters the top shell so that the pressure plate floats up due to buoyancy, and the pressure spring and the limit rod are lifted up, so that the limit rod is released from the limit hole of the sliding plate, and the sliding plate generates elastic force through the second spring on the fixed rod so that the blade pops open, and the connecting rope is cut off, so that the torsion spring shaft pops open the bottom shell so that the compressed air bag is released, so as to ensure that the raft lamp is quickly and automatically deployed and lights up, and rescue personnel are rescued and a distress signal is sent out;

[0019] S3, recovery operation;

[0020] Since a mounting plate is arranged on the top of the bearing plate, a servo motor is arranged on the mounting plate, an output shaft is connected to the output end of the servo motor, a transmission belt is arranged around the output shaft, the servo motor drives the output shaft to rotate, drives the transmission belt to rotate, and the transmission belt drives the winding assembly to operate, and the winding assembly pulls back the raft light put into the sea, and the rotating rod is adapted to the shape of the straight hole and the inclined hole, and the raft light is clamped under the action of the first spring;

[0021] S4, line collection operation;

[0022] A support plate is arranged on the bearing plate, an extension plate is arranged on the support plate, an opposing screw rod is rotatably arranged on the support plate, a moving block adapted to the opposing screw rod is sleeved on the opposing screw rod, a winding shaft is rotatably arranged on the extension plate, a steel wire is wound around the winding shaft, the middle part of the steel wire is laid on the moving block, the other end of the steel wire is passed through the passing hole and connected to the raft lamp. The design of the winding assembly enables the steel wire of the raft lamp to be neatly rolled up and released, avoiding the problem of line confusion or entanglement.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention improves the structure of the existing life raft light for marine rescue by arranging a support assembly at the rear end of the life raft, arranging a quick-release slide on the support assembly, arranging a wire-reeling mechanism on the quick-release slide, arranging a retracting mechanism inside the quick-release slide, and arranging a raft light inside the quick-release slide so as to be movable relative to the bottom of the retracting mechanism. The quick-release slide and the retracting mechanism ensure that the raft light structure of the life raft can be rapidly and reliably deployed and provide lasting lighting and distress signals in an emergency. The internal deployment structure of the raft light also enables the rescue of marine personnel without the need for additional operations by the occupants, thereby improving the rapid deployment and reliable operation of the raft light and improving the practicality of the life raft and the safety of the occupants.

[0025] 2. The present invention arranges a straight slide cylinder at a position relative to the through hole at the bottom of the bearing plate, arranges six connecting rods at the bottom of the straight slide cylinder, and arranges a horn cylinder at the bottom of the connecting rod. The straight slide cylinder is conducive to the rapid lowering of the raft lamp, and the horn cylinder is conducive to the precise positioning of the raft lamp during recovery, preventing the wire-reeling mechanism from getting stuck or becoming unsmooth during the process of recovering the raft lamp, which is conducive to improving the efficiency of the wire-reeling mechanism in recovering the raft lamp, reducing the probability of failure when recovering the raft lamp, improving the reliability of the device and reducing the maintenance frequency.

[0026] 3. The present invention arranges a mounting plate on the top of the supporting plate, arranges a servo motor on the mounting plate, connects an output shaft to the output end of the servo motor, and surrounds the output shaft with a transmission belt. The servo motor drives the output shaft to rotate, thereby driving the transmission belt to rotate. The transmission belt drives the winding assembly to operate. The winding assembly pulls back and winds the raft lamp placed in the sea. The recyclable design of the raft lamp significantly reduces the amount of marine garbage. Traditional non-recyclable raft lamps often become waste in the ocean after losing their use value, causing long-term pollution to the marine ecological environment. Recyclable raft lamps can be properly handled and reused after use, effectively preventing marine pollution.

[0027] 4. The present invention arranges a support plate on the bearing plate, arranges an extension plate on the support plate, rotatably arranges opposing screw rods on the support plate, sleeves a moving block adapted to the opposing screw rods, rotatably arranges a winding shaft on the extension plate, winds a steel wire around the winding shaft, the middle part of the steel wire is laid on the moving block, and the other end of the steel wire passes through a through hole and is connected to the raft light. The design of the winding assembly enables the steel wire of the raft light to be neatly rolled up and released, avoiding the problem of line confusion or entanglement. In an emergency, the crew can quickly and accurately operate the winding assembly to achieve rapid deployment and recovery of the raft light, thereby improving operating efficiency.

[0028] 5. The present invention arranges a cylinder on a bearing plate, arranges a driving shaft at an output end of the cylinder, connects a slider to the driving shaft, symmetrically opens movable grooves on the slider, and arranges a rotating rod and a first spring inside the movable groove. When the cylinder drives the driving shaft and the slider to move, the rotating rod is adapted to the shape of the straight hole and the inclined hole. Under the action of the first spring, the raft light is clamped and released. The retracting and releasing mechanism is designed to be very simple and intuitive, so that the crew can operate it quickly and accurately in an emergency. When facing a shipwreck or other emergency situations, every second is crucial. Quickly releasing the raft light can provide precious time for rescue.

[0029] 6. The present invention arranges a lampshade at the top of the lamp body and a trigger assembly at the bottom of the lamp body. The trigger assembly cuts off the connecting rope, and the torsion spring shaft pops open the bottom shell to release the compressed airbag, so that the raft lamp has the function of rescuing personnel. In an emergency, especially when the crew falls into the water, the compressed airbag can quickly provide buoyancy for the crew to help them quickly escape from the danger zone. This rapid response feature significantly improves the rescue efficiency and reduces the risks that may be caused by waiting for rescue.

[0030] 7. The present invention arranges a top shell at the bottom end of the lamp body and symmetrically arranges side shells on the top shell. When the trigger assembly falls onto the sea surface, seawater enters the top shell so that the pressure plate floats up due to buoyancy, and lifts up the pressure spring and the limit rod, so that the limit rod is released from the limit hole of the sliding plate. The sliding plate generates elastic force through the second spring on the fixed rod to make the blade pop open, cut off the connecting rope, and make the torsion spring shaft pop open the bottom shell to release the compressed airbag. This function can ensure that the raft lamp is quickly and automatically deployed and lights up without the need for additional operations by the occupants. This is crucial for quickly sending out distress signals in emergency situations at sea. Timely signals can greatly increase the chances of being found by search and rescue personnel.
