[0010] In some embodiments, the top diameter of the iron disc is smaller than the bottom diameter of the electromagnetic chuck; the stabilizing track assembly includes a drive assembly and a slide rail assembly.

At this point, the electromagnet hook assembly is de-energized and detaches, completing the deployment. After being released to the water surface, there is no need for manual detachment, reducing the difficulty of detaching the equipment in rough sea conditions and speeding up the detachment process.

[0017] This invention uses arc-shaped plates to prevent the cantilever cable from swaying due to strong winds, thus mitigating the risk of collisions caused by strong winds. Furthermore, the two sets of arc-shaped plates combine to form a funnel shape, wider at the top and narrower at the bottom, providing stable support for the curved bottom of the lifeboat or for cylindrical inflatable life rafts, facilitating deployment and retrieval. The cam mechanism prevents the slider from falling downwards due to gravity in the event of an accidental breakage of the track cable, improving safety and preventing injuries or fatalities during the transport of manned rescue equipment.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Marine life-saving equipment deployment devices, such as Figure 1 As shown, it includes base plate 1; The top of the base plate 1 is equipped with a lifting assembly 2 for lifting lifeboats or life rafts; The front sidewall of the base plate 1 is connected to the upper end of the stable track assembly 3 used to support the life-saving equipment; The slide rail end of the stabilizing track assembly 3 is connected to the braking assembly 4 used to prevent the life-saving equipment from falling accidentally. The bottom of the base plate 1 and the rear end of the stabilizing track assembly 3 are connected to the external platform.

[0022] like Figure 2 As shown, the lifting assembly 2 includes a cantilever assembly 21 and an electromagnet hook assembly 22; the top of the base plate 1 is connected to the bottom of the cantilever assembly 21; and the output end of the cantilever assembly 21 is connected to the top of the electromagnet hook assembly 22.

[0023] like Figure 3As shown, the cantilever assembly 21 includes a support frame 211, an upper limit rod 212, a lower limit rod 213, a cantilever 214, a first fixed pulley 215, a second fixed pulley 216, a cantilever cable 217, a cantilever motor 218, a first connecting shaft 219, a cantilever cable wheel 2110, and a support platform 2111; the support frame 211 and the support platform 2111 are symmetrically installed on the top of the base plate 1, with the support platform 2111 located behind the support frame 211. The top of the base plate 1 is fixedly connected to the bottom of the support frame 211 and the bottom of the support platform 2111; the support frame 211 consists of two sets of vertical support rods and two sets of inclined support rods. The upper end of the side wall of the vertical support rod of the support frame 211 is rotatably connected to the first fixed pulley 215 through a rotating shaft, and the lower end of the side wall of the vertical support rod of the support frame 211 is rotatably connected to the lower end of the cantilever 214; the upper and lower ends of the side wall of the inclined support rod of the support frame 211 are respectively connected to the upper limit rod. The upper limit rod 212 and the lower limit rod 213 are fixedly connected at both ends; the cantilever 214 is located between the upper limit rod 212 and the lower limit rod 213, and a groove is provided at the end of the cantilever 214. The inner wall of the groove at the end of the cantilever 214 is rotatably connected to the second fixed pulley 216 through a rotating shaft; the top of the support platform 2111 is rotatably connected to the cantilever steel cable sheave 2110 through a hinge seat, and the inner wall of the shaft hole of the two sets of cantilever steel cable sheaves 2110 is connected to the side wall of the first connecting shaft 219. Fixed connection; the top of the support platform 2111 on the left side is fixedly connected to the bottom of the cantilever motor 218, and the output end of the cantilever motor 218 is fixedly connected to the left end of the first connecting shaft 219; one end of the cantilever cable 217 is wound around the cantilever cable wheel 2110, and the other end is connected to the top of the electromagnet hook assembly 22; the side wall of the cantilever cable 217 is rolledly connected to the side wall of the first fixed pulley 215 and the second fixed pulley 216 from back to front.

[0024] The electromagnet hook assembly 22 includes an electromagnetic chuck 221, an iron plate 222, a hook 223, and a steel cable limiting rod 224; the front end of the cantilever steel cable 217 is fixedly connected to the top of the steel cable limiting rod 224; the bottom of the steel cable limiting rod 224 is fixedly connected to the top of the electromagnetic chuck 221 via a short rope; the bottom of the electromagnetic chuck 221 is magnetically connected to the top of the iron plate 222; and the bottom of the iron plate 222 is rotatably connected to the hook 223 via a hinge seat.

[0025] Preferably, the top diameter of the iron plate 222 is smaller than the bottom diameter of the electromagnetic chuck 221.

[0026] When the device is in operation and in the retracted state, the top of the cantilever 214 of the cantilever assembly 21 of the lifting assembly 2 contacts the side wall of the upper limit rod 212, and the bottom front end of the cantilever 214 contacts the side wall of the cable limit rod 224 of the electromagnet hook assembly 22. After securing lifeboats and other rescue equipment to the hook 223, the cantilever motor 218 is started, driving the first connecting shaft 219 to rotate. The first connecting shaft 219 drives the two sets of cantilever cable pulleys 2110 to rotate and release the cantilever cable 217. The cantilever 214 rotates downwards, and the top of the cantilever 214 separates from the upper limit rod 212. The cantilever 214 stops rotating when the bottom of the cantilever 214 contacts the side wall of the lower limit rod 213. At this point, the electromagnetic chuck 221 is located above the stabilizing track assembly 3. The cantilever cable 217 continues to be released, and the cantilever 214... The front bottom separates from the side wall of the steel cable limiting rod 224, and the electromagnetic chuck 221 falls vertically, placing the lifeboat and other rescue equipment on the movable end of the stabilizing rail assembly 3. At this time, the cantilever steel cable 217 continues to be released, and the rescue equipment moves down under the support of the stabilizing rail assembly 3, eventually reaching the water surface. At this time, the electromagnetic chuck 221 is de-energized, and the iron plate 222 separates from the electromagnetic chuck 221, completing the deployment. The device is limited by the lower limiting rod 213 and the steel cable limiting rod 224, so that the cantilever 214 is rotated first to suspend the rescue equipment outside the platform, and then it falls vertically, which facilitates the installation and fixation of the rescue equipment on the platform. The rescue equipment is lifted by magnetic attraction using the electromagnetic chuck 221 and the iron plate 222. After being released to the water surface, there is no need for manual unhooking, which reduces the difficulty of unhooking the equipment in poor sea conditions and speeds up the unhooking process.

[0027] For the specific application of the stable orbit component in this invention, any of the following options are possible: The stable track assembly 3 includes a drive assembly 31 and a slide rail assembly 32; the top of the base plate 1 is connected to the drive end of the drive assembly 31, and the top of the cantilever assembly 21 is connected to the pulley end of the drive assembly 31; the cable end of the drive assembly 31 is connected to the movable end of the slide rail assembly 32, and the cable end of the drive assembly 31 is connected to the brake assembly 4; the front sidewall of the base plate 1 is connected to the upper end of the slide rail assembly 32, and the rear end of the slide rail assembly 32 is connected to the external platform; the brake assembly 4 is installed on the slide rail assembly 32.

[0028] like Figure 4As shown, the drive assembly 31 includes a track motor 311, a track cable 312, a track cable pulley 313, a third fixed pulley 314, and a second connecting shaft 315. Track cable pulleys 313 are symmetrically mounted on the top of the base plate 1, and the top of the base plate 1 is rotatably connected to the track cable pulleys 313 via hinge seats. The inner walls of the shaft holes of both sets of track cable pulleys 313 are fixedly connected to the side walls of the second connecting shaft 315. The top of the base plate 1 is fixedly connected to the bottom of the track motor 311. The output end of the track motor 311 is fixedly connected to the left end of the second connecting shaft 315. The top of the support end of the slide rail assembly 32 is connected to the third fixed pulley 314. One end of the track cable 312 is wound around the track cable pulley 313, and the other end is connected to the movable end of the slide rail assembly 32. The side walls of the track cable 312 are tumblingly connected to the side walls of the third fixed pulley 314, and the side walls of the track cable 312 are connected to the brake assembly 4.

[0029] like Figures 7-8 As shown, the slide rail assembly 32 includes a track bracket 321, a slider 322, pulleys 323, a connecting plate 324, an arc plate 325, and a slide rail 326. The track bracket 321 is symmetrically mounted on the front sidewall of the base plate 1. The front sidewall of the base plate 1 is fixedly connected to the upper end of the rear sidewall of the track bracket 321, and the rear sidewall of the track bracket 321 is fixedly connected to the external platform. The inner sidewall of the track bracket 321 is fixedly connected to the outer sidewall of the slide rail 326. The slider 322 consists of a U-shaped side plate and a base plate, and multiple sets of pulleys 323 are symmetrically connected to the sidewall at the outer opening of the side plate. All pulleys 323 are hinged. The seat is rotatably connected to the slider 322, and the sidewalls of the slider 322 are vertically and rollingly connected to the inner wall of the groove of the slide rail 326; the inner bottom of the slider 322 is fixedly connected to the bottom of the track cable 312; the lower end of the inner sidewall of the slider 322 is fixedly connected to the upper end of the outer sidewall of the connecting plate 324; the inner sidewall of the connecting plate 324 is symmetrically equipped with arc plates 325, and the left and right ends of the two sets of arc plates 325 are fixedly connected to the inner sidewalls of the left and right sets of connecting plates 324 respectively; the inner sidewall of the slide rail 326 is connected to the fixed end of the brake assembly 4, and the inner wall of the slider 322 of the slide rail 326 is connected to the movable end of the brake assembly 4.

[0030] Preferably, the shape of the left-view cross-section formed by the two sets of arc-shaped plates 325 is a funnel shape that is wider at the top and narrower at the bottom.

[0031] When the device is in operation, when the life-saving equipment is placed on the arc-shaped plate 325 of the slide rail assembly 32 of the stabilizing track assembly 3, the track motor 311 of the drive assembly 31 starts, driving the second connecting shaft 315 to rotate, and simultaneously driving the two sets of track steel cable pulleys 313 to rotate, releasing the track steel cable 312; the slider 322 descends under gravity, the pulley 323 rolls down along the slide rail 326, and the arc-shaped plate 325 descends vertically until the life-saving equipment contacts the water surface and disengages, completing the deployment; for lifeboats and other manned life-saving equipment that need to be recovered, when the lifeboat docks in the middle of the track support 321, the electromagnetic chuck 221 of the electromagnet hook assembly 22 of the lifting assembly 2 is energized, and the operator attaches the iron plate 222 fixed on the lifeboat to the electromagnetic chuck 221, and the cantilever assembly... When the cantilever motor 218 of component 21 starts, it winds up the cantilever cable 217, making the cantilever cable 217 taut. At this time, the track motor 311 starts, and the arc plate 325 located below the water surface moves upward, supporting the lifeboat to move upward. When the cable limit rod 224 contacts the bottom end of the cantilever 214, the cantilever 214 rotates inward until it touches the upper limit rod 212 and stops, thereby pulling the lifeboat back to the platform. The support of the arc plate 325 can prevent the cantilever cable 217 from swaying due to strong winds and can prevent the risk of collision due to strong winds. Moreover, the shape formed by the two sets of arc plates 325 is a funnel shape that is wider at the top and narrower at the bottom, which can provide fixed support for the arc bottom surface of the lifeboat or the cylindrical inflatable life raft, making it convenient for deployment and recovery.

[0032] Regarding the specific application of the brake assembly 4 in this invention, it can be selected from any of the following: like Figure 8 As shown, the brake assembly 4 includes a cam 41, a limiting rod 42, a tension spring 43, and a rack 44; the inner sidewall of the slide rail 326 is fixedly connected to the outer sidewall of the rack 44, and the toothed end of the rack 44 faces rearward; the cam 41 is rotatably connected to the inner rear wall of the slider 322 via a rotating shaft; the upper and lower ends of the tension spring 43 are fixedly connected to the upper end of the inner outer wall of the slider 322 and the upper end of the rear sidewall of the cam 41, respectively; the middle end of the front sidewall of the tension spring 43 is fixedly connected to the rear end of the limiting rod 42; the sidewall of the limiting rod 42 is in contact with the sidewall of the track cable 312.

[0033] When the device is working, the track cable 312 of the drive assembly 31 of the stabilizing track assembly 3 is in a taut state, the limit rod 42 of the brake assembly 4 is in close contact with the side wall of the track cable 312, and the cam 41 is not in contact with the rack 44 at this time, allowing the device to move freely. When the track cable 312 breaks unexpectedly, the track cable 312 is no longer taut and blocks the limit rod 42. The tension spring 43 pulls the cam 41 outward, and the outer end of the cam 41 engages between the teeth of the rack 44, while the inner end of the cam 41 engages with the sliding end. The inner wall of the slider 322 of the rail assembly 32 is in contact; the cam 41 cannot rotate, causing the slider 322 to be stuck and preventing the slider 322 from falling further; after replacing or repairing the rail cable 312, pull the rail cable 312 upward to drive the cam 41 to rotate inward to unlock; the cam 41 can prevent the slider 322 from falling downward due to gravity when the rail cable 312 breaks accidentally, which can improve safety and prevent personnel casualties in the event of an accident.

At this time, the track motor 311 is started, and the arc plate 325 located below the water surface moves upward, supporting the lifeboat to move upward. When the cable limit rod 224 contacts the bottom end of the cantilever 214, the cantilever 214 rotates inward until it touches the upper limit rod 212 and stops, pulling the lifeboat back to the platform.

All pulleys 323 are rotatably connected to the slider 322 through hinge seats, and the side of the slider 322...
