Description

Technical Field

[0001] This invention relates to the field of underwater rescue technology, specifically to a visual underwater lighting rescue device based on fire rescue. Background Technology

[0002] With the rapid development of infrastructure and public works projects in my country, some waterways have undergone necessary modifications to meet specific needs. These modified waterways are generally quite steep, increasing the difficulty for firefighters in situations requiring drowning rescue. Using auxiliary rescue equipment can effectively reduce the risks associated with rescue operations.

[0003] A search revealed that the existing technology, specifically the visual underwater lighting and rescue device with publication number CN218617130U, includes a carbon fiber telescopic pole, a stainless steel hook, a plastic float, a waterproof flashlight, an underwater WIFI action camera, and a video display terminal. The carbon fiber telescopic pole is shaped like a telescopic fishing rod, composed of multiple sections of hollow carbon fiber tubes connected end-to-end. The stainless steel hook or plastic float is positioned at the front end of the carbon fiber telescopic pole. A mounting bracket is fitted behind the front end of the carbon fiber telescopic pole, and the waterproof flashlight and underwater WIFI action camera are fixed on the bracket. The waterproof flashlight is fixed close to the underwater WIFI action camera on the rear section of the front end of the carbon fiber telescopic pole, with the flashlight's beam pointing forward and the WIFI action camera's camera also pointing forward. The video display terminal is located outside the carbon fiber telescopic pole and is wirelessly connected to the WIFI action camera. This device can accurately assess the situation in the rescue area, confirm the location of the drowning person, eliminate the need for underwater rescue, and protect the safety of rescue personnel.

[0004] In the above technical solutions, although the water conditions can be observed during the rescue process, it is not possible to assist in putting life-saving equipment on the body parts of the person to be rescued. Rescue personnel still need to go into the water to rescue people, which still poses a great rescue risk. Therefore, we propose a visual underwater lighting rescue device based on fire rescue.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example:

[0043] like Figures 1-16As shown, this embodiment of the invention provides a visual underwater lighting rescue device based on fire rescue, including a device housing 1. A propulsion component 2 is installed at the bottom of the device housing 1. An arc-shaped bracket 3 is connected to the lower side of the propulsion component 2. Arc-shaped guide grooves 31 are provided at both ends of the arc-shaped bracket 3. An arc-shaped movable frame 32 is slidably installed inside the arc-shaped guide groove 31. Mounting grooves 33 are provided on both the inner and outer sides of the arc-shaped movable frame 32 and the arc-shaped bracket 3. Airbags 34 are installed inside the mounting grooves 33. The airbags 34 have cavities inside. Several airbags 34 are connected to an inflation component 4 installed inside the device housing 1. The inflation component 4 can inflate the airbags 34 into the cavities, causing them to expand.

[0044] An internal push spring 311 connected to the end of the arc-shaped movable frame 32 is installed inside the arc-shaped guide groove 31. The push spring 311 can push the arc-shaped movable frame 32 to move along the arc-shaped guide groove 31, so that the arc-shaped support 3 and the two arc-shaped movable frames 32 can be unfolded to form a ring, as shown in the unfolded figure. This allows the equipment to be worn around the outside of the person to be rescued, fixing the equipment to the body part of the rescuer and preventing it from detaching.

[0045] After being wrapped around the body of the person to be rescued, the airbags 34 inside the mounting slot 33 can be inflated by the inflation component 4. The airbags 34 inside the arc-shaped movable frame 32 and the arc-shaped support 3 are inflated and expanded, thereby fixing the arc-shaped movable frame 32 and the arc-shaped support 3 to the body. At the same time, the airbags 34 on the inner and outer sides of the arc-shaped movable frame 32 and the arc-shaped support 3 are inflated and expanded, thereby generating buoyancy. The buoyancy pushes the person to be rescued to the water surface, which can assist in the rescue work and reduce the risk of rescue.

[0046] Each arc-shaped bracket 3 is equipped with a touch-sensitive latching component 36 that connects to the arc-shaped movable frame 32. When the touch-sensitive latching component 36 comes into contact with the body part of the person to be rescued, the touch-sensitive latching component 36 can engage and limit the arc-shaped movable frame 32, thereby pushing the arc-shaped movable frame 32 to the unfolded state through the elasticity of the push spring 311 inside the arc-shaped guide groove 31. Both ends of the arc-shaped bracket 3 are respectively equipped with end latching components 35 for limiting the movement of the arc-shaped movable frame 32. The end latching components 35 can limit the arc-shaped movable frame 32 when it moves to the unfolded state.

[0047] In this embodiment, the touch-sensitive latching assembly 36 includes a guide seat 361, which is fixedly mounted on the lower surface of the arc-shaped bracket 3. A guide rod 362 is slidably mounted inside the guide seat 361. One end of the guide rod 362 extends slidably to the inner side of the arc-shaped bracket 3 and is fixedly mounted with a contact plate 364. A first spring 363 is fixedly mounted on one side surface of the contact plate 364. The end of the first spring 363 is mounted on the end of the guide seat 361. The other end of the guide rod 362 extends movably to the outside of the arc-shaped bracket 3 and is fixedly connected with a latching block 3. 65. The snap-fit ​​end of the snap-fit ​​block 365 moves through the outside of the arc-shaped bracket 3 and extends into the snap-fit ​​groove 366 opened on the outer surface of the arc-shaped movable frame 32. In use, the push assembly 2 can push the arc-shaped bracket 3 to move, so that the contact plate 364 can contact the human body part, thereby causing the contact plate 364 to push the guide rod 362 to move along the guide seat 361, and drive the snap-fit ​​block 365 to move synchronously, so that the snap-fit ​​end of the snap-fit ​​block 365 moves to the outside of the snap-fit ​​groove 366, thereby canceling the limiting work on the arc-shaped movable frame 32.

[0048] In this embodiment, the end-clamping assembly 35 includes a guide sleeve 351, which is fixedly installed at the end of the arc-shaped bracket 3. A limiting block 353 is movably installed inside the guide sleeve 351. A second spring 352 is fixedly installed at the lower end of the limiting block 353. The lower end of the second spring 352 is fixedly installed inside the guide sleeve 351. The upper end of the limiting block 353 movably passes into the arc-shaped guide groove 31. In the unfolded state, the upper end of the limiting block 353 is movably connected to the inside of the limiting groove 354. The limiting groove 354 is located on the lower surface of the arc-shaped movable frame 32. After the push spring 311 pushes the arc-shaped movable frame 32 to move to the designated position along the arc-shaped guide groove 31, the second spring 352 can push the limiting block 353 to move along the inside of the guide sleeve 351, pushing the upper end of the limiting block 353 into the limiting groove 354, thus completing the limiting work of the arc-shaped movable frame 32.

[0049] In this embodiment, the inflation assembly 4 includes a mounting cavity 41, which is disposed inside the equipment housing 1. A sealing plate is installed on the top of the mounting cavity 41. Several compressed air tanks 42 are installed inside the mounting cavity 41, and compressed gas is contained inside the compressed air tanks 42. An inflation pipe 43 is connected to one end of the compressed air tank 42. An air inlet valve 44 is installed at one end of the inflation pipe 43 near the compressed air tank 42, and the other end of the inflation pipe 43 is connected to an air inlet connector 46. The air inlet connector 46 is fixedly installed on the outer wall of the arc-shaped bracket 3, and several air pipes connected to the airbag 34 are connected inside the air inlet connector 46. A one-way valve 45 is installed at one end of the inflation tube 43 near the air inlet connector 46. The one-way valve 45 is electrically connected to a controller 47. The one-way valve 45 can seal the inflation tube 43 after inflation to prevent gas backflow. The controller 47 is electrically connected to the air inlet valve 44. During use, the controller 47 can control the air inlet valve 44 to open, thereby delivering the compressed gas inside the compressed gas tank 42 to the inflation tube 43. The compressed gas then enters the air inlet connector 46 and several air pipes connected to the airbag 34 through the inflation tube 43, causing the airbag 34 to inflate and expand, thereby carrying out rescue work.

[0050] In this embodiment, the propulsion component 2 includes an electric slide rail 21, which is fixedly installed on the lower surface of the equipment housing 1. A connecting seat 22 is fixedly installed on the moving end of the electric slide rail 21. One end of the connecting seat 22 is provided with a slot for installing an arc-shaped bracket 3, and the arc-shaped bracket 3 is movably installed in the slot.

[0051] In this embodiment, a movable plate 23 is provided on the upper side of the connecting seat 22. A limiting pin 24 is fixedly installed on the lower surface of the movable plate 23. The lower end of the limiting pin 24 extends movably into the slot and is movably connected to the limiting groove 25 opened on the upper surface of the arc-shaped bracket 3. A movable rod 26 is fixedly installed on one end of the movable plate 23. The lower end of the movable rod 26 extends movably into the piston cylinder 28 in the slot. The piston cylinder 28 is fixedly installed in the slot. A piston 27 is slidably installed inside the piston cylinder 28. The piston 27 is fixedly installed on the lower end of the movable rod 26. A limiting seat 210 is fixedly installed on the lower end of the piston 27. The limiting seat 210 is located below the piston 27. A connecting air pipe 211 is connected to the outer wall of the piston cylinder 28 below the piston 27. The end of the air inlet pipe 211 is connected to the inside of the inflation pipe 43. The outer wall of the movable rod 26 is fitted with a third spring 29. The lower end of the third spring 29 is fixedly installed on the upper end of the piston cylinder 28, and the upper end of the third spring 29 is fixedly installed on the lower surface of the movable plate 23. When the airbag 34 inflation pipe 43 is in an inflated state, the gas will enter the piston cylinder 28 through the air inlet pipe 211 and be located on the lower side of the piston 27. The airflow pushes the piston 27 to move along the piston cylinder 28, thereby driving the movable plate 23 to move the limiting pin 24, so that the limiting pin 24 moves to the outside of the limiting groove 25, thereby releasing the limitation on the arc-shaped bracket 3, so that the arc-shaped bracket 3 can be separated from the connecting seat 22 and separated from the equipment housing 1 in the rescue state, which is conducive to the rescued personnel floating to the surface.

[0052] In this embodiment, a fixed seat 221 is fixedly installed in the empty groove on the other side of the connecting seat 22. A fourth spring 222 is fixedly installed on one side of the fixed seat 221. A support frame 223 is fixedly installed at one end of the fourth spring 222. The end of the support frame 223 is slidably installed on the connecting seat 22. The end of the connecting seat 22 slides into the empty groove for installing the arc-shaped bracket 3. A connecting frame 224 is fixedly installed at the end of the connecting seat 22. The end of the connecting frame 224 is movably connected to the outside of the arc-shaped bracket 3. When the limiting pin 24 separates from the limiting groove 25, the elasticity of the fourth spring 222 can push the end of the connecting seat 22 to push the connecting frame 224 to move. The connecting frame 224 can push the arc-shaped bracket 3 and the arc-shaped bracket 3 to move outward of the empty groove, which can assist in the separation work, so that the rescue equipment can float smoothly and carry out the rescue work.

[0053] In this embodiment, lighting lamps 8 and cameras 7 are fixedly installed at both ends of the device housing 1. A drive propeller 6 is installed at the tail end of the device housing 1, and submersible propellers 5 are installed on both sides of the device housing 1. The lighting lamps 8, cameras 7, drive propellers 6, and submersible propellers 5 are all electrically connected to the controller 47. The controller 47 is electrically connected to a wireless transceiver module installed inside the device housing 1. The wireless transceiver module is used to receive signals transmitted from the outside to control the controller 47 to operate, and can also transmit the data captured by the camera 7 to the outside world for easy operation. As a working device, the device housing 1 is equipped with a mobile power supply to power the electrical appliances of the device and ensure that the device works normally. When in use, it can transmit signals with external devices through a wireless transceiver module and control the controller 47 to work, thereby starting the propeller 6 and the diving propeller 5 to complete the movement, realizing the device's diving and surfacing. The controller 47 can also activate the lighting 8 and the camera 7, which facilitates external devices to observe the rescue situation of the device and the underwater environment, improving the visualization performance. The controller 47 can also control the electric slide rail 21 to work, thereby moving the arc-shaped support 3.

[0054] Working principle:

[0055] When in use, the push spring 311 can push the arc-shaped movable frame 32 to move along the arc-shaped guide groove 31, so that the arc-shaped bracket 3 and the two arc-shaped movable frames 32 can unfold to form a ring, which can be worn around the outside of the body of the person to be rescued, and fix the equipment to the body part of the rescuer to prevent it from falling off.

[0056] The inflation component 4 inflates the airbags 34 inside the mounting slot 33. The airbags 34 inside the arc-shaped movable frame 32 and the arc-shaped support 3 are inflated and expanded, thus fixing the arc-shaped movable frame 32 and the arc-shaped support 3 to the body. At the same time, the airbags 34 on the inner and outer sides of the arc-shaped movable frame 32 and the arc-shaped support 3 are inflated and expanded, thus generating buoyancy. The buoyancy pushes the person to be rescued to the water surface, which can assist in the rescue work and reduce the risk of rescue.

[0057] The device housing 1 is equipped with a mobile power supply to power the electrical appliances of the device and ensure that the device works normally. During use, it can transmit signals with external devices through the wireless transceiver module and control the controller 47 to start the propeller 6 and the diving propeller 5 to complete the diving and movement to the location of the person to be rescued, thus realizing the diving and surfacing of the device. The controller 47 can also activate the lighting 8 and the camera 7 to facilitate external devices to observe the rescue situation and the underwater environment, improving the visibility performance. The controller 47 can also control the electric slide rail 21 to move the arc-shaped support 3.
