Description

Technical Field

[0001] The invention relates to the technical field of underwater emergency response, and in particular to a diving emergency light. Background Art

[0002] In marine scientific exploration activities, it is necessary to dive into the water to observe and explore. In the underwater environment, electromagnetic wave signals will experience multiple reflections, refractions and scattering, resulting in multipath propagation effects. This multipath propagation will cause the Doppler frequency shift of the signal, resulting in signal distortion and interference. In addition, there are a large number of fish and algae in the ocean, as well as water ripples. The salinity, temperature and suspended matter in the water will affect the propagation and attenuation of the signal. The blocking effect of these obstacles when the electromagnetic wave is transmitted greatly weakens the propagation of the signal, which results in the current inability of radio signals to propagate over long distances in the ocean. Therefore, when people are in danger in the water, it is difficult to send a distress signal to people on the shore or on the ship. Even if a signal is sent, it is difficult for rescuers to determine the location of the people in distress in the water. Summary of the invention

[0027] As another embodiment of the present invention, the base 3 is connected to the lower cover 2 via a fixing screw 18 , and a second waterproof ring 19 is provided at the nut of the fixing screw 18 .

[0028] As another embodiment of the present invention, the base 3 and the lower cover 2 are both in the shape of an inwardly concave arc, and spring pieces 17 are provided on both sides of the base 3 , with a gap between the spring pieces 17 and the lower cover 2 .

[0029] As another embodiment of the present invention, the control board 4 is provided with a vibration sensing inductor, and the vibration sensing inductor is connected to a vibration sensor arranged on the housing. When the vibration sensor does not sense vibration, the control board 4 sends a distress signal.

[0030] The present invention provides a diving emergency light, which can be worn on the arm, does not take up space and can effectively transmit the emergency situation of underwater workers to surface personnel through ultrasonic and laser emission. The device is also equipped with a laser beam to guide the rescue direction, and the device also has an underwater lighting function.

[0031] The installation process of this equipment is as follows: install the magnet 15 on the mounting plate 14, connect the mounting back plate to the lower cover 2, put the first waterproof ring 11 on the lens of the spotlight 9, install it in the first mounting hole 10, fix the control board 4 to the mounting plate 14, fix the battery 16 to the mounting plate 14, fix the ultrasonic generator 5 to the mounting plate 14 and set it close to the tail of the shell, install the transparent plate 7 in the upper cover 1, apply sealant, install the five laser transmitters 6 in the slots of the upper cover 1, insert the male terminals of all components into the female terminals of the control board 4, put the upper cover 1 and the lower cover 2 together and fix and lock them with screws, fix the base 3 to the sleeve, and adsorb the whole machine and the base 3 together to complete the assembly.

[0032] The streamlined shape of this device greatly reduces the resistance of water to the device during movement, which reduces the load on the operator when working underwater. According to actual effective experiments: the transmission speed of sound underwater is about three times that in the air, about 1500m / s, so the sound wave transmission signal becomes the second preferred option underwater besides optical fiber transmission, so the ultrasonic generator 5 is designed at the tail of this device, and the illuminating spotlight 9 is set at the front end of the shell. The upper cover 1 and the lower cover 2 are made of die-cast aluminum alloy body, and the spotlight 9 uses PC lens with 3030 SMD lamp beads, and uses aluminum substrate as the plate. While ensuring the brightness, the lamp beads of the spotlight 9 have a good heat dissipation effect. The attenuation of blue / green light with a visible light wavelength of 0.47 to 0.58 microns in seawater is much smaller than that of other wavelengths. This characteristic makes the blue / green laser have better directionality underwater, can reduce scattering and interference, and has stronger penetration ability. Therefore, the top of the device is designed with five laser transmitters 6 that can emit blue / green laser beams and a switch button 8. Long pressing the switch button 8 turns the machine on / off, and short pressing the switch button 8 triggers an emergency signal.

[0033] When a diver encounters an emergency underwater and needs to be rescued by surface personnel or pull back the traction rope, he only needs to click the switch button 8 on the device, and the ultrasonic generator 5 will emit ultrasonic waves through the ultrasonic generating hole 21. The ultrasonic waves will be located by the ultrasonic capture device on the water surface. The frequency emitted by the ultrasonic generator 5 is three short and three long, corresponding to the Morse code of the international SOS signal. At the same time as the device triggers the emergency device, the blue / green laser emitted by the laser transmitter 6 lights up alternately, and the spotlight 9 at the front also begins to flash. The flashing of the laser and the light provide accurate direction guidance for the rescuers. The device has two batteries 16 built in. The battery 16 uses a nickel-metal hydride lithium battery, which can ensure that the device can work for a long time to reach the rescue personnel. Long press the switch button 8 to turn off the device.

[0034] The above is the active rescue mode, and the device also has an emergency rescue mode. The device has built-in motion sensing structural elements, and the vibration sensing inductor and components form a sensing circuit to sense whether the person is in motion. When the water pressure is too high, the huge pressure can cause people to faint, or bump into other objects and other emergencies that cause coma. When the device detects no movement within thirty seconds, that is, it is in a static state, the vibration sensing inductor is automatically triggered, and the ultrasonic generator 5, laser transmitter 6 and spotlight 9 cooperate to send out an emergency distress signal until the rescue personnel arrive, and then long press the switch button 8 to turn off the device.

[0035] The device is wearable. The base 3 is tied or embroidered on the user's sleeve using a sewing machine. The shell has two magnets 15 with strong magnetism built in. You only need to gently place the shell on the base 3 to automatically adsorb it. At the same time, slightly move the shell until the four fixing screws 18 are all inserted into the predetermined holes of the lower cover 2 to complete the wearing. The base 3 is made of stainless iron, and its corrosion resistance can meet the marine use environment. It also has the characteristic of being adsorbed by the magnet 15, tightly adsorbing the two together. Regardless of the impact of the water flow or bumping into obstacles, the front and rear forces will be absorbed by its own magnetism and the four fixing screws 18. Since the device has a streamlined shape and no corners or barbs, it also avoids the force of being hooked up and down by other objects.

[0036] In terms of waterproofing of the equipment, the first waterproof ring 11 is set at the spotlight 9, and the second mounting hole 20 adopts a pressure-resistant step design, which is tightly mounted on the upper cover 1. While having a sealing effect, the greater the water pressure encountered, the more the transparent plate 7 will be squeezed into the inside of the shell. Because of the existence of the step, it will be more solid, effectively ensuring the stability and reliability of the equipment. At the same time, the second waterproof ring 19 is set on the fixing screw 18, and waterproof glue is also applied to various holes to prevent water from entering the interior of the equipment and ensure the normal operation of the equipment in an emergency.

[0037] The device is designed with the ultrasonic generator 5, which has a long transmission distance for sound waves and provides accurate positioning; the streamlined design of the appearance effectively reduces the resistance of water flow resistance to diving operators; the magnetic installation design is convenient, simple and efficient to install and use, and has strong adsorption force, while also avoiding the risk of front / back warping when encountering strong water flow, which can easily cause the device to fall off; the front end of the device is designed with the spotlight 9 for lighting, which can illuminate and trigger the flashing auxiliary indication of the direction in an emergency; the top of the device is designed with five blue / green laser beams, which will flash alternately to provide prompts when the device is triggered in an emergency, providing a more accurate auxiliary positioning function for search and rescue personnel; the transparent plate 7 on the top of the device adopts a pressure-resistant step design, and the greater the underwater pressure, the firmer it is, which effectively guarantees the stability and reliability of the device. The shrapnel 17 is provided on both sides of the base 3, which can be expanded or reduced accordingly to cope with the thickness of the arms of people from different countries, making the base 3 highly flexible to install.

[0038] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
