Description

Technical Field

[0001] This invention relates to the field of underwater rescue technology, and more specifically, to an underwater rescue device for fire emergency use. Background Technology

[0002] In fire emergency rescue scenarios, underwater rescue accidents are subject to extremely high requirements for the safety, efficiency and adaptability of rescue equipment due to the complex environment and short rescue window. Existing underwater rescue devices mostly adopt the floating rescue on the water surface or the rescue mode by divers by hand.

[0003] Traditional floating rescue devices can only wait for the person who has fallen into the water to approach on the surface, and cannot actively dive underwater to carry out rescue. For people who have sunk underwater or are trapped in narrow underwater spaces, the success rate of rescue is extremely low. Some devices with diving capabilities often use heavy counterweights to achieve diving, which makes the diving posture difficult to control, and the weight must be discarded when surfacing, making the operation cumbersome and posing secondary safety hazards. The clamping mechanisms of existing underwater rescue devices are mostly exposed designs, which are easily entangled by weeds, fishing nets and other debris during movement on the surface or underwater, causing the clamping action to jam and making it impossible to complete the rescue operation normally. Summary of the Invention

[0004] To overcome the above deficiencies, the present invention provides a fire emergency underwater rescue device that overcomes or at least partially solves the above technical problems.

[0005] This invention is implemented as follows: This invention provides a fire emergency underwater rescue device, including a rescue chamber, with an underwater rescue actuator disposed at the bottom of the rescue chamber. The underwater rescue actuator includes... The protective shell is fixed to the bottom of the life-saving capsule by bolts. A support plate is fixed to the inner wall of the protective shell. Two vertically connected sliding grooves are opened on the support plate. A slider is slidably arranged inside the sliding groove. An arc-shaped clamping claw is arranged below the slider. The main gas tank is located on both sides of the life-saving capsule and is equipped with an electromagnetic water valve. An auxiliary gas tank is located inside the protective shell.

[0006] In a preferred embodiment, a slide rail is fixedly provided on the top of the support plate, and two slide plates are slidably disposed on the surface of the slide rail, with each of the two slide plates being fixedly connected to two sliders.

[0007] In a preferred embodiment, the inner top wall of the protective shell is rotatably provided with a drive rod, both ends of which are hinged to connecting rods, and the other end of the connecting rod is hinged to the top of the slide plate.

[0008] In a preferred embodiment, the protective shell is provided with a waterproof grass wrapping mechanism, which includes a connecting platform fixed to the bottom of the slider. A lifting sleeve is slidably provided on the inner wall of the connecting platform. The lifting sleeve is fixedly connected to an arc-shaped clamping claw. A first lead screw is rotatably provided inside the connecting platform, and the first lead screw is threaded inside the lifting sleeve.

[0009] In a preferred embodiment, the connecting platform is internally equipped with a worm gear and a worm, which mesh with each other, and the bottom of the worm gear is fixedly connected to the first lead screw.

[0010] In a preferred embodiment, a splined shaft is rotatably mounted on the inner wall of the protective shell, and a splined sleeve is coaxially fixed on the worm gear, the splined sleeve being slidably fitted onto the surface of the splined shaft.

[0011] In a preferred embodiment, a mounting plate is integrally formed on the support plate, a first drive gear is rotatably mounted on the bottom of the mounting plate, a first bevel gear is coaxially fixed on the bottom of the first drive gear, and a second bevel gear is coaxially fixed on the surface of the spline shaft, with the first bevel gear and the second bevel gear meshing with each other.

[0012] In a preferred embodiment, a second drive gear is rotatably mounted on the bottom of the mounting plate, the first drive gear and the second drive gear mesh with each other, and a ratchet is coaxially fixed inside the second drive gear.

[0013] In a preferred embodiment, a frustum is rotatably mounted on the bottom of the mounting plate, a pawl is hinged to the frustum, and a second lead screw is coaxially fixed inside the frustum.

[0014] In a preferred embodiment, a piston bolt is slidably disposed inside the auxiliary gas storage tank, a piston rod is fixedly disposed at the bottom of the piston bolt, a drive plate is fixedly disposed at the bottom of the piston rod, a drive sleeve is fixedly disposed at the top of the drive plate, and the second lead screw is threadedly sleeved inside the drive sleeve.

[0015] The present invention provides a fire emergency underwater rescue device, the beneficial effects of which include: 1. By setting up an underwater rescue actuator, when the rescue capsule moves near the person who has fallen into the water, the gas inside the main gas tank is transferred to the auxiliary gas tank, and water is drawn into the main gas tank through an electromagnetic water valve, thereby increasing the overall weight of the rescue capsule and facilitating its descent. After clamping, the water inside the main gas tank is discharged out through the electromagnetic water valve, and the gas inside the auxiliary gas tank is transferred back to the main gas tank, thereby increasing the overall buoyancy of the rescue capsule.

[0016] 2. By setting up a waterproof groove wrapping mechanism, when the rescue capsule moves towards the person in the water, the arc-shaped clamping claw is located inside the protective shell. At this time, the protective shell prevents water plants from getting tangled on the arc-shaped clamping claw during the movement of the rescue capsule, thus avoiding the problem of the arc-shaped clamping claw being unable to move when it needs to clamp the person in the water. When the main air tank is filled with water, the rescue capsule enters the diving mode. At this time, the arc-shaped clamping claw extends outward from inside the protective shell and can work normally to clamp the person in the water. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0021] Reference Figures 1-8This invention provides a technical solution: a fire emergency underwater rescue device, including a rescue chamber 1, an underwater rescue actuator at the bottom of the rescue chamber 1, the underwater rescue actuator including a protective shell 201 and a main gas tank 206, the protective shell 201 being fixed to the bottom of the rescue chamber 1 by bolts, a support plate 202 being fixed to the inner wall of the protective shell 201, two vertically penetrating grooves 203 being provided on the support plate 202, a slider 204 being slidably disposed inside the grooves 203, and the slider 204 being located below the slider 204. An arc-shaped clamping claw 205 is provided, with a clamping pad on the claw 205. Main air tanks 206 are located on both sides of the rescue capsule 1, and electromagnetic water valves 207 are installed on the main air tanks 206. An auxiliary air tank 208 is located inside the protective shell 201. The main air tanks 206 and the auxiliary air tanks 208 are connected by an air pipe. An underwater rescue actuator is installed to drive multiple vector thrusters on the rescue capsule 1 to rotate, thereby enabling the rescue capsule 1, carrying the protective shell 201, to move in the water. In its initial state, the main air tank 206 is filled with dry compressed air, which facilitates the movement of the rescue capsule 1 on the water surface through buoyancy. When the rescue capsule 1 moves near the person in the water, the gas inside the main air tank 206 is transferred to the auxiliary air tank 208, and water is drawn into the main air tank 206 through the electromagnetic water valve 207, thereby increasing the overall weight of the rescue capsule 1 and facilitating its descent. The rescue capsule 1 moves above the person in the water, positioning the person in two arc-shaped embraces. Between the clamping claws 205, the two sliders 204 are moved in opposite directions, thereby causing the two arc-shaped clamping claws 205 to move in opposite directions, clamping the person in the water. After clamping, the movement of the rescue capsule 1 moves the person towards the surface, discharging the water inside the main gas tank 206 through the electromagnetic water valve 207, and transferring the gas from the auxiliary gas tank 208 back into the main gas tank 206, increasing the overall buoyancy of the rescue capsule 1. This completes the underwater rescue, which is more suitable for scenarios requiring underwater rescue compared to existing technologies. Reference Figures 1-8The top of the support plate 202 is fixedly provided with a slide rail 209. Two slide plates 210 are slidably arranged on the surface of the slide rail 209. The two slide plates 210 are fixedly connected to two sliders 204 respectively. The inner top wall of the protective shell 201 is rotatably provided with a drive rod 211 through a deep groove ball bearing. Both ends of the drive rod 211 are hinged to connecting rods 212 through fisheye joints. The other end of the connecting rod 212 is hinged to the top of the slide plate 210. A waterproof servo motor is provided inside the protective shell 201. The output end of the waterproof servo motor and the drive rod 211 are fixedly connected through a coupling. By setting the drive rod 211, the user starts the waterproof servo motor, which drives the drive rod 211 to rotate. When the drive rod 211 rotates, it drives the connecting rods 212 on both sides to swing. Under the limiting cooperation of the slide rail 209, the slide plate 210 drives the slider 204 to move radially towards the center of the support plate 202, thereby driving the two arc-shaped clamping claws 205 to move in opposite directions. Reference Figures 1-8 The protective shell 201 is internally equipped with a waterproof grass-wrapping mechanism, which includes a connecting platform 301 fixed to the bottom of the slider 204. A lifting sleeve 302 is slidably mounted on the inner wall of the connecting platform 301, and the lifting sleeve 302 is fixedly connected to an arc-shaped clamping claw 205. A first lead screw 303 is rotatably mounted inside the connecting platform 301, and the first lead screw 303 is threaded into the inside of the lifting sleeve 302. By providing the waterproof grass-wrapping mechanism, when the rescue capsule 1 moves towards the person falling into the water, the arc-shaped clamping claw 205... The curved gripper 205 is located inside the protective shell 201. The protective shell 201 protects the rescue capsule 1 from getting tangled in the curved gripper 205 during its movement, preventing it from being unable to move when rescue is needed. When the main air tank 206 is filled with water, the rescue capsule 1 enters the diving mode. At this time, the curved gripper 205 extends outward from inside the protective shell 201 and can work normally to hold the person who has fallen into the water. Reference Figures 1-8The connecting platform 301 is internally equipped with a worm gear 304 and a worm 305, which mesh with each other. The bottom of the worm gear 304 is fixedly connected to the first lead screw 303. The inner wall of the protective shell 201 is rotatably equipped with a spline shaft 306. A spline sleeve 307 is coaxially fixed on the worm 305 and slides on the surface of the spline shaft 306. By setting the worm gear 304 and the worm 305, when the spline shaft 306 rotates, it drives the spline sleeve 307 to rotate. The spline sleeve 307 drives the worm 305 to rotate, which causes the worm gear 304 to drive the first lead screw 303 to rotate. Through the threaded connection between the first lead screw 303 and the lifting sleeve 302, the lifting sleeve 302 drives the arc-shaped clamping claw 205 to move downward, thereby causing the arc-shaped clamping claw 205 to disengage from the inside of the protective shell 201. Reference Figures 1-8 A mounting plate 308 is integrally formed on the support plate 202. A first drive gear 309 is rotatably mounted on the bottom of the mounting plate 308. A first bevel gear 310 is coaxially fixed to the bottom of the first drive gear 309. A second bevel gear 311 is coaxially fixed to the surface of the spline shaft 306. The first bevel gear 310 and the second bevel gear 311 mesh with each other. A second drive gear 312 is rotatably mounted on the bottom of the mounting plate 308. The first drive gear 309 and the second drive gear 312 mesh with each other. A ratchet 313 is coaxially fixed inside the second drive gear 312. A frustum 314 is rotatably mounted on the bottom of the mounting plate 308. A pawl 315 is hinged to the frustum 314. A second lead screw 316 is coaxially fixed inside the frustum 314. A torsion spring is provided between the pawl 315 and the frustum 314. By setting the ratchet 313 and the pawl 315, when the second lead screw 316 is mounted on the frustum 314, a second lead screw 316 is coaxially fixed to the frustum 314. A torsion spring is provided between the pawl 315 and the frustum 314. When the second lead screw 316 rotates, it drives the frustum 314 to rotate, and the frustum 314 drives the pawl 315 to rotate. At this time, the pawl 315 and the ratchet teeth on the ratchet wheel 313 abut against each other, so that the ratchet wheel 313 rotates synchronously. Through the meshing connection of the first drive gear 309 and the second drive gear 312, the second drive gear 312 drives the first drive gear 309 to rotate. Through the meshing connection of the first bevel gear 310 and the second bevel gear 311, the second bevel gear 311 drives the spline shaft 306 to rotate. When the second lead screw 316 rotates in the opposite direction, the reverse rotation of the pawl 315 causes it to rotate after abutting against the ratchet teeth on the ratchet wheel 313. At this time, the ratchet wheel 313 does not move, and the pawl 315 rotates on its own axis, which avoids the problem that after the gas inside the auxiliary gas tank 208 returns to the main gas tank 206, the arc-shaped clamping claw 205 returns to the protective shell 201. Reference Figures 1-8A piston bolt 317 is slidably installed inside the auxiliary gas tank 208. A piston rod 318 is fixed to the bottom of the piston bolt 317, a drive plate 319 is fixed to the bottom of the piston rod 318, and a drive sleeve 320 is fixed to the top of the drive plate 319. A second lead screw 316 is threaded inside the drive sleeve 320. By setting the piston bolt 317, after the rescue capsule 1 moves to the vicinity of the person who has fallen into the water, the piston bolt 317 inside the auxiliary gas tank 208 is driven to move downward. Due to the principle of air pressure difference, the piston bolt 317 moves downward through the air pipe. Under normal conditions, the piston bolt 317 inside the main gas tank 206 moves synchronously, causing the gas inside the main gas tank 206 to be drawn into the auxiliary gas tank 208, and external water is drawn into the main gas tank 206 through the electromagnetic water valve 207. When the piston bolt 317 moves, it drives the piston rod 318 to move, thereby driving the drive plate 319 and the drive sleeve 320 to move. Through the threaded connection between the drive sleeve 320 and the second lead screw 316, the second lead screw 316 is rotated.

[0022] Specifically, the working process or principle of this underwater rescue device for fire emergencies is as follows: During use, multiple vector thrusters on the rescue capsule 1 are driven to rotate, causing the rescue capsule 1, carrying the protective shell 201, to move in the water. Since the main air tank 206 initially contains dry compressed air, buoyancy facilitates the movement of the rescue capsule 1 on the water surface. When the rescue capsule 1 moves near the person in the water, the piston 317 inside the auxiliary air tank 208 is driven to move downwards. Due to the pressure difference principle and with the air pipe connected, the piston 317 inside the main air tank 206 moves synchronously, causing the gas inside the main air tank 206 to be drawn into the auxiliary air tank 208. Inside, water from the outside is drawn into the main gas storage tank 206 via the electromagnetic water valve 207. When the piston bolt 317 moves, it drives the piston rod 318 to move, thereby driving the drive plate 319 and drive sleeve 320 to move. Through the threaded connection between the drive sleeve 320 and the second lead screw 316, the second lead screw 316 rotates. When the second lead screw 316 rotates, it drives the frustum 314 to rotate. The frustum 314 drives the pawl 315 to rotate. At this time, the pawl 315 and the ratchet teeth on the ratchet wheel 313 abut against each other, causing the ratchet wheel 313 to rotate synchronously. Through the meshing connection between the first drive gear 309 and the second drive gear 312, the second drive gear 312 drives... The first drive gear 309 rotates, and through the meshing connection of the first bevel gear 310 and the second bevel gear 311, the second bevel gear 311 drives the spline shaft 306 to rotate. When the spline shaft 306 rotates, it drives the spline sleeve 307 to rotate. The spline sleeve 307 drives the worm gear 305 to rotate, which in turn drives the first lead screw 303 to rotate. Through the threaded connection between the first lead screw 303 and the lifting sleeve 302, the lifting sleeve 302 drives the arc-shaped clamping jaw 205 to move downward, thereby causing the arc-shaped clamping jaw 205 to disengage from the inside of the protective shell 201. The user then starts the waterproof servo motor, which drives the drive rod 211 to rotate. When the drive rod 211 rotates, it carries... The connecting rods 212 on both sides swing, and under the limiting action of the slide rail 209, the slide plate 210 drives the slider 204 to move radially towards the center of the support plate 202, thereby driving the two arc-shaped clamping claws 205 to move in opposite directions, so that the two arc-shaped clamping claws 205 can clamp the person who has fallen into the water. After clamping, the movement of the rescue capsule 1 will move the person who has fallen into the water towards the water surface, and the water in the main gas tank 206 will be discharged out through the electromagnetic water valve 207. The gas in the auxiliary gas tank 208 will be transferred back into the main gas tank 206, thereby improving the overall buoyancy of the rescue capsule 1.
