Description

Technical Field

[0001] The invention relates to the field of water rescue, and in particular to a personal water rescue signal marker lamp. Background Art

[0002] As we all know, a personal drowning search and rescue beacon is a specially designed device, usually worn by rescuers or life jackets, used in drowning search and rescue operations. The device has excellent waterproof performance and can work normally in underwater environments. It usually uses light-emitting diodes (LEDs), flashes or other conspicuous lighting methods to emit easily detectable signals so that it can be quickly found in dark or low-visibility conditions. Its power supply is generally provided by lithium batteries or dry batteries to ensure that it can continue to emit light for a period of time after falling into the water. Some position lights also have an automatic activation function, which will automatically turn on once it falls into the water.

[0003] Some advanced position lights even integrate the global positioning system (GPS) or other positioning technologies, which can accurately determine the location of the drowning person, providing great convenience for rescuers' search and rescue work. In general, personal drowning search and rescue beacon position lights play a vital role in water rescue, marine operations and other water activities.

[0004] However, the existing personal drowning search and rescue signal beacon position lamp is prone to the following problems in use: the structural position of the existing search and rescue signal beacon position lamp is relatively set in one position, which makes it not flexible enough during the search and rescue process, resulting in a relatively limited search and rescue range; it is also prone to angle restrictions or inflexibility, and thus cannot achieve all-round beacon indication, resulting in limited warning effect, so that the warning range of the existing technology cannot meet the search and rescue needs at a longer distance or in a more complex environment. Therefore, the present invention proposes a personal drowning search and rescue signal beacon position lamp. Summary of the invention

[0035] like Figure 1-7The personal drowning search and rescue signal position light shown in the figure, when used for searching and rescuing people who have fallen into the water, first put the arc-shaped head ring 2 on the people's head and fix it on the head through the head fixing belt 1, so that the movable bracket 5, the threaded tube 6, the U-shaped seat 7, the movable mounting seat 8, and the position light body 9 can be relatively worn and fixed on the head; then the position light body 9 is used to transmit light and then send out an easily detectable signal, so that it can be quickly found in the dark or low visibility conditions, thereby playing an important role in the search and rescue of people who have fallen into the water. In search and rescue use, by setting a telescopic mechanism and using the stepping motor 502 in the telescopic mechanism to drive the screw 503 to rotate, the threaded tube 6 can be threaded upward on the screw 503, and then the threaded tube 6 can be moved upward from the telescopic chamber 501, so that the overall length between the threaded tube 6 and the movable bracket 5 can be extended, which can expand the luminous warning range of the position indicator light body 9 during search and rescue work, ensuring that the search and rescue warning range is farther; at the same time, by setting a left and right swinging mechanism and using the extension and contraction of the output end of the electric telescopic rod 302, the spur rack 303 is driven to move left and right and mesh with the gear 304 for transmission, and then the gear 304 and the first rotating shaft 4 can be driven to rotate forward and reversely.

When the worm 706 rotates, it is meshed with the worm wheel 707 for transmission, and drives the second rotating shaft 708 to rotate forward and reversely. The second rotating shaft 708 drives the movable mounting seat 8 and the position light body 9 to swing back and forth to perform search and rescue activities, which can further expand the warning range; and the left and right swinging of the position light body 9, the front and back swinging of the position light body 9, and the telescopic activity of the position light body 9, the three can be coordinated at the same time, not only can the warning distance and warning surface of the position light body 9 be wider, so as to meet the search and rescue needs at a longer distance or in a more complex environment, and by coordinating the front and back swinging of the position light body 9 with the left and right swinging, a full range of beacon indications can be achieved, ensuring that the position light body 9 is more flexible in search and rescue use, greatly reducing the limitations of the relatively limited search and rescue range in the past, and making the overall search and rescue effect better.

[0036] In summary, the personal water rescue beacon position light can be worn and fixed on the head, which plays an important role in the search and rescue of people who fall into the water; its telescopic mechanism can increase the range of the light warning, ensuring a longer search and rescue warning distance; the left and right swing mechanism allows the main body of the position light to swing left and right for warning and search and rescue, widening the warning range; the front and back swing mechanism allows the main body of the position light to swing back and forth for warning and search and rescue, further expanding the range; and these three can also cooperate at the same time, making the warning distance and warning surface wider, meeting the search and rescue needs at longer distances and in more complex environments. At the same time, the main body of the position light can swing back and forth and left and right at the same time, which can realize all-round beacon indication, making it more flexible in search and rescue use, greatly reducing the limitations of the relatively limited search and rescue range in the past, and making the overall search and rescue effect better.
