Description

TECHNICAL FIELD

[0001] The present application relates to the field of lighting devices, in particular, to a life-saving position indicating lamp with strong environmental adaptability and a life-saving system. BACKGROUND

[0002] The life-saving position indicating lamp is a life-saving device used for sea rescue, which is designed to automatically light up for position indication after entering the water, so that the survivor can identify the position of the life-saving device and the rescuer can identify the position of the survivor.

[0003] Some existing life-saving position indicating lamps use seawater batteries for power supply. After the life-saving position indicating lamp is put into seawater, seawater enters the seawater battery inside the life-saving position indicating lamp to form an electrolyte, so that the seawater battery starts to automatically light up the life-saving position indicating lamp for position indication. However, such life-saving position indicating lamp is easily affected by the storage environment. When the life-saving position indicating lamp is stored for a long time in a humid and hot environment or an environment with sharp temperature changes, the seawater battery will absorb moisture in the environment to start, causing the position indicating lamp to abnormally excite, thereby affecting the subsequent normal use.

[0004] Therefore, there is a need for a life-saving position indicating lamp that can adapt to different storage environments for a long time to meet the use requirements. CONTENT OF THE INVENTION

[0034] The features and performances of the environment-adaptable life-saving position light and life-saving system of the present application are further described in detail below in combination with embodiments.

[0035] Embodiment 1

[0036] As shown in Figure 1 and Figure 2 , the present embodiment provides an environment-adaptable life-saving position light, which comprises a position light body 100, a seawater battery assembly 200, a wire 110 connecting the position light body 100 and the seawater battery assembly 200, and a float 120 that can float on the sea surface, and the position light body 100 is connected to the float 120; the seawater battery assembly 200 comprises a battery shell 210 provided with a positive electrode 220 and a negative electrode 230 at two ends respectively, the battery shell 210 is provided with a positive electrode protection cap 240 and a negative electrode protection cap 250 sleeved on the positive electrode 220 and the negative electrode 230 at two ends respectively, the battery shell 210 is provided with an exciting mechanism therein, the two ends of the battery shell 210 are provided with openings 340, and the positive electrode protection cap 240 and the negative electrode protection cap 250 are provided with clamping portions 350 clamped in the openings 340; the exciting mechanism is used to generate gas to make the positive electrode protection cap 240 and the negative electrode protection cap 250 separate from the battery shell 210 when being impacted in seawater, and make seawater enter the battery shell 210 to activate the seawater battery assembly 200 to light the position light body 100. Wherein, the exciting mechanism comprises a containing groove 260 provided on the inner wall of the battery shell 210, a gas generating element 270 provided in the containing groove 260, and a cover 370 used to clamp and close the containing groove 260, and the gas generating element 270 is sodium azide, which is used to generate gas when being impacted.

[0037] The environment-adaptable lifesaving position indicating lamp provided by the embodiment of the present application is used to be dropped into the sea surface, and when the seawater battery assembly 200 falls and hits the sea surface, the impact on the exciting mechanism in the battery shell 210 causes the gas generating element 270 to generate nitrogen gas, which pushes the cover 370 away and enters the battery shell 210 to rapidly increase the air pressure and push the positive electrode protection cap 240 and the negative electrode protection cap 250 to overcome the clamping force between the opening 340 and the clamping portion 350 and fly away from the battery shell 210, so that the external seawater enters the battery shell 210 to form an electrolyte to activate the seawater battery assembly 200, and then the seawater battery assembly 200 lights up the position indicating lamp body 100 through the wire 110, and the position indicating lamp body 100 is floated on the sea surface by the buoy 120 as a rescue indicating light.

[0038] When the environment-adaptable lifesaving position indicating lamp provided by the embodiment of the present application is not used for storage, the positive electrode protection cap 240 and the negative electrode protection cap 250 are clamped and sealed at both ends of the battery shell 210 through the clamping portion 350 and the opening 340, respectively, which can effectively improve the environmental adaptability of the environment-adaptable lifesaving position indicating lamp, avoid the entry of external water vapor into the battery shell 210 to cause the seawater battery assembly 200 to be activated by mistake in a long-term storage and high-temperature and high-humidity storage environment, effectively prolong the service life of the environment-adaptable lifesaving position indicating lamp, prolong the inspection cycle, reduce the maintenance cost, and improve the storage and use economy.

[0039] In addition, the environment-adaptable lifesaving position indicating lamp provided by the embodiment of the present application can also be used with a life jacket, a lifeboat or a life slide, and the position indicating lamp body 100 of the environment-adaptable lifesaving position indicating lamp is connected to the life jacket, the lifeboat or the life slide for rescue indication when used.

[0040] Embodiment 2

[0041] As shown in Figure 3 and Figure 4 The environment-adaptable lifesaving position indicating lamp provided by the embodiment of the present application is roughly the same as the environment-adaptable lifesaving position indicating lamp provided by the embodiment 1, and the difference lies in that the outer wall of the battery shell 210 is further connected with a pressable thimble 280 in the embodiment, the bottom of the thimble 280 penetrates into the accommodating groove 260, and the thimble 280 hits the gas generating element 270 to generate gas when pressed; a reset spring 290 is arranged between the thimble 280 and the battery shell 210, and the reset spring 290 is used to drive the thimble 280 to move reversely and reset after being pressed; a protective cover 330 detachably connected to the outer wall of the battery shell 210 is sleeved on the thimble 280, and the protective cover 330 is connected to the outer wall of the battery shell 210 through threads.

[0042] The environment-adaptive lifesaving position indicating lamp provided by the embodiment of the present application is convenient for the user to manually activate the seawater battery assembly 200 to supply power to the position indicating lamp body 100. When the user needs to manually activate the seawater battery assembly 200, the user only needs to quickly press the thimble 280 connected to the outer wall of the battery shell 210, so that the thimble 280 moves axially to impact the gas generating element 270 arranged in the containing groove 260. When the gas generating element 270 is impacted, nitrogen is generated to rapidly increase the air pressure in the battery shell 210 and push the positive electrode protection cap 240 and the negative electrode protection cap 250 away from the battery shell 210. At this time, the user can throw the seawater battery assembly 200 into seawater, so that the external seawater enters the battery shell 210 to form an electrolyte to activate the seawater battery assembly 200, and then the seawater battery assembly 200 lights up the position indicating lamp body 100 through the wire 110, and makes the position indicating lamp body 100 float on the sea surface through the buoy 120 as a rescue indicating light.

[0043] In addition, the reset spring 290 is arranged between the thimble 280 and the battery shell 210, and is used to drive the pressed thimble 280 to move reversely to reset. After the user presses the thimble 280 to move axially to compress the reset spring 290 and impact the gas generating element 270 arranged in the containing groove 260 to fail to generate gas, the user releases the thimble 280, so that the compressed reset spring 290 pushes the thimble 280 to move reversely to reset, thereby facilitating the user to repeatedly press the thimble 280 to move axially to impact the gas generating element 270 arranged in the containing groove 260.

[0044] The protection cover 330 is arranged on the thimble 280 and is threadedly connected to the outer wall of the battery shell 210. By arranging the protection cover 330 which is threadedly connected to the outer wall of the battery shell 210 and is sleeved on the thimble 280, the protection cover 330 can be used to sleeve and protect the thimble 280, so that the thimble 280 is prevented from being pressed to impact the gas generating element 270 arranged in the containing groove 260 to generate gas due to being accidentally touched during transportation and storage.

[0045] Embodiment 3

[0046] As shown in Figure 5 and Figure 6 The environment-adaptive lifesaving position indicating lamp provided by the embodiment of the present application is convenient for the user to manually activate the seawater battery assembly 200 to supply power to the position indicating lamp body 100. When the user needs to manually activate the seawater battery assembly 200, the user only needs to quickly press the thimble 280 connected to the outer wall of the battery shell 210, so that the thimble 280 moves axially to impact the gas generating element 270 arranged in the containing groove 260. When the gas generating element 270 is impacted, nitrogen is generated to rapidly increase the air pressure in the battery shell 210 and push the positive electrode protection cap 240 and the negative electrode protection cap 250 away from the battery shell 210. At this time, the user can throw the seawater battery assembly 200 into seawater, so that the external seawater enters the battery shell 210 to form an electrolyte to activate the seawater battery assembly 200, and then the seawater battery assembly 200 lights up the position indicating lamp body 100 through the wire 110, and makes the position indicating lamp body 100 float on the sea surface through the buoy 120 as a rescue indicating light.

[0047] The environment-adaptive lifesaving position indicating lamp provided by the embodiment of the present application is capable of making the impact hammer 310 move along the guide cylinder 300 to stretch the connecting spring 320 to impact the gas generating element 270 to generate nitrogen when the seawater battery assembly 200 falls from high altitude to impact the sea surface, and making the connecting spring 320 drive the impact hammer 310 to reciprocatingly move along the guide cylinder 300 to repeatedly impact the gas generating element 270, thereby ensuring that the gas generating element 270 is fully triggered to generate gas under a certain impact force to activate the seawater battery assembly 200 and then light the position indicating lamp body 100 through the wire 110.
