DETAILED DESCRIPTION

[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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1-Figure 7 The present embodiment provides a technical solution: a water rescue equipment carried on a ship body, comprising a rescue boat 100, the rescue boat 100 is connected to a support 200, a joystick 210 is hinged on the support 200, a lifebuoy 220 is clamped at the end of the joystick 210, a mounting ring 230 is also hinged at the end of the joystick 210, a salvage net 231 is connected to the mounting ring 230, when the mounting ring 230 swings and moves away from the lifebuoy 220, the lifebuoy 220 is in a launching state, and when the mounting ring 230 swings and contacts the lifebuoy 220, the lifebuoy 220 is in a salvaging state.

[0028] When rescuing a drowning person, the rescue boat 100 is moved close to the person to be rescued. If the drowning person is unconscious, the lifebuoy 220 is adjusted to a salvaging state so that the distance between the rescue boat 100 and the drowning person is within the swing range of the joystick 210. The joystick 210 is used to control the movement of the lifebuoy 220, and the salvaging net 231 is used to salvage the unconscious drowning person. If the drowning person is not unconscious, the lifebuoy 220 is adjusted to an ejection state. When the distance between the rescue boat 100 and the drowning person is within the ejection distance of the lifebuoy 220, the joystick 210 is adjusted so that the lifebuoy 220 is aimed at the drowning person, the lifebuoy 220 is ejected, and the drowning person is rescued. After the drowning person puts on the lifebuoy 220 by himself, the lifebuoy 220 is retracted.

[0029] A handle 211 is provided on the end of the joystick 210 away from the lifebuoy 220, and the joystick 210 is operated by the handle 211. The joystick 210 and the support 200 are hinged by a connecting seat to ensure the swing flexibility of the joystick 210, and the joystick 210 and the connecting seat are rotatably connected, so that the joystick 210 can be rotated to adjust the direction of the hole of the lifebuoy 220 when the lifebuoy 220 is in a salvage state. An electric power assist is provided between the joystick 210 and the connecting seat, and between the connecting seat and the support 200. This electric power assist mechanism can adopt the power assist structure of the vehicle steering wheel, so as to achieve the effect of saving effort when operating the joystick 210.

[0030] A pressure chamber 241 is provided in the joystick 210, and a pressurizing tube 240 communicating with the pressure chamber 241 is connected to the side wall. A one-way valve is provided on the pressurizing tube 240. A plug rod 221 is fixedly connected to the lifebuoy 220, and the plug rod 221 is inserted into the pressure chamber 241. An electric clamping block 250 is slidably connected to the joystick 210, and a slot is provided on the side wall of the plug rod 221. The electric clamping block 250 penetrates the outer wall of the joystick 210 and is inserted into the slot. After high-pressure gas is added to the pressure chamber 241 through the pressurizing tube 240, the electric clamping block 250 is released, so that the lifebuoy 220 pops out.

[0031] Air is injected into the pressure chamber 241 through the pressurizing tube 240, so that the pressure chamber 241 is in a high-pressure state, and then the electric card block 250 is controlled to slide and pull out the slot on the plug rod 221. At this time, the high pressure is released, and the plug rod 221 is ejected, so that the lifebuoy 220 connected to the plug rod 221 is simultaneously ejected to the person who falls into the water. After the lifebuoy 220 is pulled back, the plug rod 221 is inserted into the pressure chamber 241 and the electric card block 250 is controlled to slide and be inserted into the slot on the plug rod 221. At this time, the lifebuoy 220 is reset.

[0032] A guide seat 223 is connected to the rescue boat 100, and a traction rope 222 is inserted into the guide seat 223. The two ends of the traction rope 222 are respectively connected to the rescue boat 100 and the insertion rod 221. An elastic ball 224 is sleeved on the traction rope 222, and a sleeve 225 is connected to the elastic ball 224. A bracket 227 is fixedly connected to the sleeve 225. A positioning block 226 is elastically connected to the bracket 227, and the positioning block 226 abuts against the traction rope 222.

[0033] When the life buoy 220 is ejected, the traction rope 222 pulls the life buoy 220. When the life buoy 220 is ejected, the traction rope 222 quickly slides on the guide seat 223, and the positioning block 226 is pulled away from the traction rope 222 to adjust the position of the elastic ball 224 on the traction rope 222. When the positioning block 226 is released, the elastic component (such as a rubber block, elastic cotton, etc.) connected between the positioning block 226 and the bracket 227 pushes the positioning block 226 so that the positioning block 226 abuts against the traction rope 222. 22, so that the release length of the traction rope 222 is controlled, and then the ejection distance of the lifebuoy 220 is controlled. When the lifebuoy 220 is ejected to the required distance, the elastic ball 224 can abut against the guide seat 223. At this time, the elastic ball 224 hits the guide seat 223 and deforms, and the deformation recovery speed of the elastic ball 224 is slow, so that the traction rope 222 will not be tightened instantly to cause the lifebuoy 220 to rebound, and then the lifebuoy 220 can be ejected to a predetermined position.

[0034] The piston cylinder 300 is fixedly connected to the operating rod 210, and the piston rod 310 is slidably connected inside the piston cylinder 300. A tension spring 340 is connected between the piston rod 310 and the piston cylinder 300. The piston cylinder 300 is connected to an air injection pipe 350, which is inserted into the insertion rod 221 and connected to the lifebuoy 220. When the mounting ring 230 swings and moves away from the lifebuoy 220, the piston rod 310 can be released, so that the piston cylinder 300 injects air into the lifebuoy 220.

[0035] A low-density support ring is provided inside the lifebuoy 220, and this support ring is fixedly connected to the insertion rod 221. When the lifebuoy 220 is in the salvage state, the interior is not inflated, ensuring that the buoyancy generated by the lifebuoy 220 during salvage will not increase the operating force of the operating rod 210. When in the ejection state, the mounting ring 230 swings down and away from the lifebuoy 220. At this time, the piston rod 310 is released, so that the tension spring 340 pulls the piston rod 310 to slide into the piston cylinder 300, so that the air in the piston cylinder 300 is transferred to the lifebuoy 220 through the air injection pipe 350. At this time, the lifebuoy 220 expands, ensuring that the lifebuoy 220 has sufficient buoyancy after being ejected to rescue the person who falls into the water.

[0036] The operating rod 210 is fixedly connected with an articulated seat 330 , the mounting ring 230 is fixedly connected with a rotating shaft 331 , a pull rope 320 is wound around the rotating shaft 331 , and the pull rope 320 is connected to the piston rod 310 . When the mounting ring 230 swings and moves away from the lifebuoy 220 , the pull rope 320 is released from the rotating shaft 331 .

[0037] When the mounting ring 230 swings downward, the rotating shaft 331 rotates clockwise. At this time, the pull rope 320 wrapped around the rotating shaft 331 is released, so that the pull rope 320 no longer pulls the piston rod 310, and the tension spring 340 can pull the piston rod 310 into the piston cylinder 300. Conversely, when the mounting ring 230 swings upward, the rotating shaft 331 rotates counterclockwise. At this time, the rotating shaft 331 stores the pull rope 320, so that the pull rope 320 pulls the piston rod 310 to slide outward, so that the piston cylinder 300 draws out the air in the lifebuoy 220 to ensure that the buoyancy of the lifebuoy 220 will not affect the salvage during the salvage state.

[0038] An air passage connected to the lifebuoy 220 is provided in the insertion rod 221, and a mounting frame 360 ​​is fixedly connected in the air passage, and a pin rod 370 is slidably connected to the mounting frame 360, and a conical block 371 is connected to the end of the pin rod 370, and a spring 372 is connected between the conical block 371 and the mounting frame 360. A conical surface matching the conical block 371 is provided in the air passage, and the inner diameter of the air passage is larger than the diameter of the conical block 371; an air nozzle 351 is fixedly connected to the end of the air injection pipe 350, and an air hole 352 is provided on the side wall of the air nozzle 351. When the air injection pipe 350 is inserted into the air passage of the insertion rod 221, it can push the conical block 371 to slide, so that the air injection pipe 350 is connected to the air passage through the air hole 352.

[0039] After the insertion rod 221 is inserted into the pressure chamber 241, the air injection pipe 350 can also be inserted into the airway of the insertion rod 221. At this time, the air nozzle 351 pushes the conical block 371 to slide, so that the air injection pipe 350 is connected with the airway through the air hole 352, and the airway extends to the low-density support ring in the lifebuoy 220. At this time, the swing of the mounting ring 230 can control the expansion and contraction of the lifebuoy 220;

[0040] The air injection pipe 350 is fixedly connected to the pressure chamber 241 through a frame to ensure that the air injection pipe 350 can face the airway of the insertion rod 221 when the insertion rod 221 is inserted, and the outer wall of the insertion rod 221 fits with the inner wall of the airway end to ensure that when the pressure chamber 241 is pressurized, a large amount of high-pressure gas will not enter the lifebuoy 220 to cause excessive expansion and damage of the lifebuoy 220. When the lifebuoy 220 is ejected, the air nozzle 351 is away from the conical block 371. At this time, the spring 372 rebounds the conical block 371 to close the airway, thereby ensuring that the lifebuoy 220 will not leak.

[0041] The rescue boat 100 is connected to a control console 400 , and the support 200 is fixedly connected to the control console 400 .

[0042] The rescuer stands on the operating platform 400 and operates the operating lever 210 .

[0043] A plurality of mounting tubes 420 are fixedly connected to the rescue boat 100, and slide bars 421 are slidably connected inside the plurality of mounting tubes 420. The tops of the plurality of slide bars 421 are hinged to the operating table 400, and a return spring 422 is connected between the slide bars 421 and the mounting tubes 420. A flywheel 410 is rotatably connected inside the operating table 400.

[0044] When salvaging an unconscious person who has fallen into the water and the water waves are large, causing the rescue boat 100 to shake, the flywheel 410 is started and driven to rotate by the motor. When the flywheel 410 rotates at a high speed, a gyro effect is generated, which makes the control panel 400 tend to maintain its original position, so that the rescue boat 100 moves relative to the control panel 400 when shaking. At this time, the slide bar 421 can slide in the corresponding installation tube 420 to ensure the position stability of the control panel 400, so that the swing amplitude of the life buoy 220 in the salvage state with the rescue boat 100 is reduced or eliminated.

[0045] The multiple installation tubes 420 are all connected with exhaust pipes 423 , and the multiple exhaust pipes 423 are all provided with solenoid valves. The gas injection pipe 350 is connected with an air guide pipe 430 , and the multiple exhaust pipes 423 are all connected with the air guide pipe 430 .

[0046] If the rescue boat 100 shakes too much, the distance that the corresponding slide bar 421 slides in the corresponding installation tube 420 increases. At this time, the air pressure in the installation tube 420 increases greatly. A pressure sensor is arranged in the installation tube 420. When the control system detects that the air pressure sensor detects an increase in air pressure, the solenoid valve on the exhaust pipe 423 connected to the installation tube 420 is controlled to open, so that the gas in the installation tube 420 is transmitted to the air injection pipe 350 through the corresponding exhaust pipe 423 and the air guide pipe 430, and then can enter the life buoy 220. At this time, the life buoy 220 expands. If the life buoy 220 is in the water at this time, it can float up and make the joystick 210 away from the unconscious person, so as to avoid collision and secondary injury to the unconscious person. In addition, the inflated life buoy 220 is relatively soft, so even if it collides with the unconscious person, the injury can be reduced.

[0047] The control system simultaneously obtains the swing angle and amplitude of the rescue boat 100. When the swing angle and amplitude of the rescue boat 100 are large and continuous, when the rescue boat 100 swings to near horizontal, it controls multiple solenoid valves to open, and when the pressure values ​​detected by the pressure sensors in the multiple installation tubes 420 are close to being equal, it controls multiple solenoid valves to close. Then, when the rescue boat 100 continues to swing so that the pressure value detected by one or more pressure sensors increases, the corresponding solenoid valve is opened, so that the lifebuoy 220 can still expand;

[0048] In the initial state, the slide bar 421 is pressed down by the operating table 400 and the components installed on the operating table 400 and slides down into the corresponding mounting tube 420, so that there is a positive pressure in the mounting tube 420. Therefore, when the operating table 400 swings, the slide bar 421 can also slide in the direction away from the mounting tube 420. A hinge ball is arranged on the top of the slide bar 421, and a hinge hole is opened on the operating table 400 to match the clearance of the hinge ball, so as to ensure that the swing of the operating table 400 is not interfered.

[0049] A hydraulic rod 440 is fixedly connected to the rescue boat 100 , and a pad 450 is fixedly connected to the top of the hydraulic rod 440 . When the hydraulic rod 440 is extended, the pad 450 abuts against the lower surface of the control table 400 so that the table surface of the control table 400 is parallel to the rescue boat 100 .

[0050] When the rescue boat 100 is not swinging and the life buoy 220 is in the ejection state, the hydraulic rod 440 can be controlled to extend so that the pad 450 moves up and abuts against the lower surface of reference figure 400, so that the control panel 400 can be parallel to the deck of the rescue boat 100, so that the rescue personnel can stand stably on the control panel 400.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
