[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1, as Figures 1 to 6 As shown, an underwater lost device includes a stainless steel cylinder 1, an articulated seat 2, an articulated block 3 and a lost device top cover 4. The articulated seat 2 is fixedly connected to the surface of the stainless steel cylinder 1, the installation height of the articulated seat 2 is higher than the top opening height of the stainless steel cylinder 1, and the installation position of the articulated seat 2 is located on the outer surface of the stainless steel cylinder 1. The articulated block 3 is fixedly connected to the surface of the lost device top cover 4, and the installation position of the articulated block 3 is located on the outer surface of the lost device top cover 4. The articulated block 3 is rotatably connected to the articulated seat 2 via a first rotating shaft, and the lost device top cover 4 is rotatably connected to the stainless steel cylinder 1 through the cooperation of the articulated block 3 and the articulated seat 2.
[0028] The interior of the stainless steel cylinder 1 is fixedly connected to a support disc 7, and the installation position of the support disc 7 is located in the middle and lower part of the interior of the stainless steel cylinder 1. The surface of the support disc 7 is fixedly connected to a spring 8, and the top of the spring 8 is fixedly connected to a float bottle 9. The inner bottom surface of the lost device top cover 4 is connected to a wire releaser 10 through a second rotating shaft. A fluorocarbon line 11 is wound around the surface of the wire releaser 10. One end of the fluorocarbon line 11 is fixedly connected to the wire releaser 10, and the other end of the fluorocarbon line 11 is fixedly connected to the surface of the float bottle 9. A 3V lithium battery 20 is fixedly connected to the surface of the float bottle 9. A handle 19 is also fixedly connected to the surface of the float bottle 9. The installation position of the handle 19 is located on the outside of the 3V lithium battery 20. A mercury switch 21 and a light-emitting tube 22 are fixedly connected to both sides of the surface of the handle 19, and the 3V lithium battery 20, the mercury switch 21 and the light-emitting tube 22 are electrically connected by a wire. During use, when the instrument leaves the working platform and is impacted by water, and the center of gravity of the instrument changes, resulting in imbalance and other phenomena, the instrument will roll over, flip, tilt, etc. At this time, the top cover 4 of the lost device is opened, and the spring 8 stretches to eject the float bottle 9. After the float bottle 9 is out of the warehouse, it is restricted by the traction of the fluorocarbon line 11 and rotates 180 degrees. At this time, the mercury switch 21 is turned on, and the light-emitting tube 22 is powered by the 3V lithium battery 20, so that the light-emitting tube 22 flashes, making it easier for search and rescue personnel to find it.
[0029] Example 2. In addition to all the technical features of Example 1, this embodiment also includes: an electromagnetic lock 12 is fixedly connected to the installation groove opened inside the lost device top cover 4, and a locking block 5 is fixedly connected to the surface of the stainless steel cylinder 1. The installation position of the locking block 5 is symmetrical with the hinge seat 2. A socket 6 is opened on the side surface of the locking block 5 facing the hinge seat 2. When in use, the lost device top cover 4 is rotated to close the lost device top cover 4 and the stainless steel cylinder 1. At this time, the electromagnetic lock 12 is controlled so that the lock tongue of the electromagnetic lock 12 can be extended into the socket 6 opened on the surface of the locking block 5. At this time, the floating bottle 9 can compress the spring 8 through the limiting action of the line releaser 10, so that the spring 8 is in a compressed state, providing power for the subsequent pop-up of the floating bottle 9.
[0030] The line releaser 10 is located at a depth within the stainless steel cylinder 1 that enables the float bottle 9 to squeeze the spring 8, ensuring that there is sufficient power for the subsequent float bottle 9 to pop out.
[0031] A 12V lithium battery 14 is fixedly connected to the interior of the stainless steel cylinder 1 below the support disc 7. The 12V lithium battery 14 is electrically connected to the electromagnetic lock 12 through a connecting cable 13, and can provide power to the electromagnetic lock 12 so that the electromagnetic lock 12 can function stably.
[0032] An omnidirectional angle offset switch 16 is fixedly connected to the interior of the stainless steel cylinder 1 below the 12V lithium battery 14. During use, when the instrument leaves the work platform and is impacted by water, and the center of gravity of the instrument changes, causing imbalance, etc., the instrument may tip over, flip, tilt, etc. When the tilt angle is greater than a certain angle of 30 degrees, the omnidirectional angle offset switch 16 is turned on, and the lock tongue of the electromagnetic lock 12 can be controlled to retract, thereby opening the top cover 4 of the lost device and allowing the float bottle 9 to pop out.
[0033] Example 3. In addition to all the technical features of Example 1, this embodiment also includes: the interior of the stainless steel cylinder 1 is fixedly connected with bolt seats 23 in a circular array near its bottom end, and a bottom sealing cover 18 is provided at the bottom of the stainless steel cylinder 1. The surface of the bottom sealing cover 18 is provided with mounting holes 25 in a circular array. The number of the mounting holes 25 is consistent with the number of the bolt seats 23. A fastening bolt 24 is provided inside each mounting hole 25. The fastening bolt 24 is threadedly connected to the bolt seat 23. The bottom sealing cover 18 is fixedly connected to the stainless steel cylinder 1 through the fastening bolt 24.
[0034] The connections between the bottom sealing cover 18, 12V lithium battery 14, omnidirectional angle offset switch 16 and the stainless steel cylinder 1 are filled with sealant 17, which is used to seal the gaps between each connection part and the stainless steel cylinder 1 to prevent water from entering the interior and ensure the normal operation of the lost device underwater.
[0035] Working Principle: When in use, first, the stainless steel cylinder 1 is fixed to the instrument with the fixing bolts, and the whole device is in a relatively stable state. In the initial state, the omnidirectional angle offset switch 16 is not triggered, the electromagnetic lock 12 locks the top cover 4 of the device, the spring 8 is in a compressed state, the float bottle 9 is confined inside the stainless steel cylinder 1, the light-emitting tube 22 is not emitting light, and the entire device is waiting for a possible trigger event;
[0036] During use, if the instrument leaves the work platform, such as after falling into water, the instrument tilts due to the impact of water, the change of the center of gravity of the instrument itself, and other factors. When the tilt angle is greater than a certain angle (such as 30 degrees), the omnidirectional angle offset switch 16 is triggered and turned on. Since the omnidirectional angle offset switch 16 is turned on, the 12V lithium battery 14 starts to power the electromagnetic lock 12 through the power supply cable 13. At this time, the tongue of the electromagnetic lock 12 moves out of the socket 6, unlocking the top cover 4 of the lost device;
[0037] During this process, after the electromagnetic lock 12 is unlocked, the top cover 4 of the lost device opens under the elastic force of the spring 8. The spring 8 stretches and pops the float bottle 9 out of the stainless steel tube 1. After the float bottle 9 pops out, it is connected to the instrument through the fluorocarbon line 11. At the same time, the fluorocarbon line 11 is also connected to the line releaser 10, which limits the range of movement of the float bottle 9.
[0038] During this process, after the float bottle 9 pops out, it rotates 180 degrees under the restraint of the fluorocarbon line 11 and the line releaser 10, turning on the mercury switch 21. At this time, the 3V lithium battery 20 supplies power to the light-emitting tube 22 through the circuit, and the light-emitting tube 22 starts to flash. The flashing of the light-emitting tube 22 can provide an obvious visual signal on the water surface, making it easier to find;
[0039] During this process, the float bottle 9 rises in the water by its own buoyancy, because it is connected to the stainless steel cylinder 1 through the fluorocarbon line 11 and the line releaser 10, and the stainless steel cylinder 1 is connected to the instrument, so the underwater instrument can be found along the fluorocarbon line 11 on the water surface, thereby locating and salvaging the lost instrument. During the whole process, the sealing material glue 17 ensures the waterproof performance of the equipment, and the waterproof charging connector 15 can charge the battery so that the lost device can work normally. The lost device has high safety. When salvaging underwater, it can effectively avoid the risks of drowning, being washed away by undercurrents, and being attacked by aquatic creatures during manual salvage; at the same time, the salvage accuracy is high and the efficiency is high, and it can find and salvage instruments in complex environments (such as deep sea, deep underground, etc.), saving time and effort.
[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
