DETAILED DESCRIPTION

[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0036] Embodiment 1: A remote-controlled life buoy for ship, such as Figure 1-Figure 7As shown, it includes a support plate frame 1, a wave splitter 11, a floating block 12, a turbine 13, a dual-axis motor 14, a rope reel 15 and a pull rope 16. The front part of the support plate frame 1 is connected to the wave splitter 11, and the middle part of the wave splitter 11 is arched. The arched wave splitter 11 can reduce the water resistance, so that the support plate frame 1 moves faster on the water surface. The remote-controlled life buoy for the ship is provided with sixteen floating blocks 12. Two adjacent floating blocks 12 can be spliced ​​with each other, and the sixteen floating blocks 12 and the support plate frame 1 The support plate frame 1 is spliced ​​into a life buoy. The left and right sides of the bottom of the support plate frame 1 are connected to turbines 13. The turbine 13 and the external control device are electrically connected through the control module. The turbine 13 can drive the support plate frame 1 to travel on the water surface. The external control device can be a remote control, a mobile phone, etc. A dual-axis motor 14 is arranged in the middle of the support plate frame 1. The dual-axis motor 14 and the external control device are electrically connected through the control module. The upper and lower output shafts of the dual-axis motor 14 are connected to the rope wheel 1 through a coupling. 5. A pull rope 16 is wound around the rope wheel 15. The head end of the pull rope 16 is wound around the rope wheel 15. The end of the pull rope 16 passes through the left part of the support plate frame 1 and passes through each floating block 12 along the circular direction. Finally, the end of the pull rope 16 passes through the right part of the support plate frame 1. The end of the pull rope 16 is also wound around the rope wheel 15. In this way, when the rope wheel 15 rotates forward, the rope wheel 15 will relax the head end and the end of the pull rope 16 at the same time, so that the pull rope 16 can also relax the floating block 12. The sixteen floating blocks 1 2 can be relaxed. When the support plate frame 1 drives the floating block 12 to move forward on the water surface, since the floating block 12 is relaxed, the floating block 12 can change from a "round shape" to an "elliptical shape". The elliptical shape can reduce the resistance of the water to the floating block 12, and can speed up the forward movement of the floating block 12. When the rope wheel 15 is reversed, the rope wheel 15 will simultaneously tighten the head end and the end of the pull rope 16, so that the floating block 12 can be tightened by the pull rope 16, and the floating block 12 is restored from an "elliptical shape" to a "round shape" to form a life buoy.

[0037] The remote-controlled life buoy for ship is installed on the hull. When using the remote-controlled life buoy for ship to rescue a person who falls into the water, the personnel on board can drive the boat to the vicinity of the person who falls into the water, and then place the remote-controlled life buoy for ship on the water surface, and then control the turbine 13 and the dual-axis motor 14 to work together through the external control device, the turbine 13 will drive the support plate frame 1 and the floating block 12 to approach the person who falls into the water, and at the same time, the output shaft of the dual-axis motor 14 will automatically stop working after 2 seconds of forward rotation, and the output shaft of the dual-axis motor 14 will rotate forward to drive the rope wheel 15 to rotate forward, and the forward rotation of the rope wheel 15 will relax the head end and the end of the pull rope 16 at the same time, so that the pull rope 16 can also relax the floating block 12, and the sixteen floating blocks 12 can be relaxed, and in the process of the support plate frame 1 driving the floating block 12 to move forward on the water surface, since the floating block 12 is relaxed, the floating block 12 can change from a "circular" to an "elliptical" The elliptical shape can reduce the resistance of water to the floating block 12, and can speed up the forward movement of the floating block 12, thereby shortening the rescue time and carrying out timely rescue. When the remote-controlled life buoy of the ship approaches the person who falls into the water, the turbine 13 can be controlled to stop working through the external control device, and the output shaft of the dual-axis motor 14 can be controlled to reverse and automatically stop working after 2 seconds. The reverse rotation of the output shaft of the dual-axis motor 14 drives the rope wheel 15 to reverse, and the rope wheel 15 will simultaneously tighten the head and end of the pull rope 16, so that the floating block 12 can be tightened by the pull rope 16, and the floating block 12 is restored from an "elliptical shape" to a "circular shape" to form a life buoy, and the person who falls into the water can put the remote-controlled life buoy of the ship on himself, and then the turbine 13 is controlled to move through the external control device to make the supporting plate frame 1 and the floating block 12 close to the hull, and then the person who falls into the water can be rescued onto the hull.

[0038] Embodiment 2: Based on embodiment 1, Figure 8-Figure 9 As shown, it also includes an expansion piece 2, an air cylinder 21, a pressure block 22, a compression spring 23 and an air guide tube 24. The floating block 12 is connected with an expansion piece 2, and the expansion piece 2 can be an expansion air block or an expansion air bag. The expansion piece 2 forms a circle, and the circular expansion piece 2 surrounds the outer ring of the floating block 12. The buoyancy of the floating block 12 can be enhanced by the expansion piece 2. The inside of the floating block 12 is connected with an air cylinder 21, and the air guide tube 24 is connected between the air cylinder 21 and the adjacent expansion piece 2. The gas in the air cylinder 21 can enter the expansion piece 2 through the air guide tube 24, and the expansion piece 2 expands and bulges. The air cylinder 21 is fixedly connected with a pressure block 22 through a piston rod, and the pressure block 22 and the adjacent floating block 12 are squeezed and matched. The pressure spring 23 is connected between the pressure block 22 and the adjacent air cylinder 21, and the compression spring 23 is wound around the piston rod.

[0039] Initially, the floating block 12 is in a spliced ​​state, the floating block 12 is in a state of squeezing the pressing block 22, the expansion member 2 is in an expanded state, and the compression spring 23 is in a compressed state; in the process of the remote-controlled life buoy of the ship approaching the drowning person, the rope wheel 15 rotates forward to relax the pull rope 16, the pull rope 16 loosens the floating block 12, the floating block 12 is relaxed, the floating block 12 no longer squeezes the adjacent pressing block 22, the compression spring 23 drives the pressing block 22 and the piston rod to move, the piston rod will draw the gas inside the expansion member 2 back into the air cylinder 21, so that the expansion member 2 becomes flat after being deflated. The state of the expansion piece 2 will not reduce the speed of the floating block 12 due to the increase in area of ​​the expansion piece 2. After that, when the remote-controlled life buoy of the ship approaches the person who falls into the water, the rope wheel 15 is reversed to tighten the pull rope 16. The pull rope 16 tightens the floating block 12. The floating blocks 12 are spliced ​​together. The floating blocks 12 will squeeze the adjacent pressing blocks 22. The movement of the pressing blocks 22 drives the piston rod to move. The gas in the air cylinder 21 enters the expansion piece 2 through the air guide pipe 24, and the expansion piece 2 expands and bulges. In this way, the buoyancy of the floating block 12 can be enhanced by the expansion piece 2, so as to rescue the person who falls into the water.

[0040] like Figure 10-12 As shown, it also includes a guide wheel 3, a rotating shaft 31, a full gear 32, a clamping assembly 36 and a driving assembly. Two rotating shafts 31 are connected to the left and right sides of the wave splitter 11, and the upper and lower sides of the rotating shaft 31 are connected to the guide wheels 3. The outside of the guide wheel 3 is evenly provided with a plurality of friction grooves along the circumferential direction, and the friction between the guide wheel 3 and the pull rope 16 can be increased through the friction grooves. The pull rope 16 passes through two adjacent guide wheels 3 respectively, and the pull rope 16 can be guided by the guide wheel 3. The top of the guide wheel 3 is provided with a full gear 32, and the two adjacent full gears 32 are meshed with each other. A clamping assembly 36 is provided between the bottom of the rotating shaft 31 and the support plate frame 1. The clamping assembly 36 is composed of a guide cylinder, a clamping spring, a clamping ball and a clamping disk. The clamping disk is provided with a plurality of clamping holes, and the clamping disks are all connected to the bottom of the rotating shaft 31. The left and right sides of the part are fixedly connected with guide cylinders, and a card ball is slidably connected in the guide cylinders. The card ball and the card hole of the card disk are squeezed and matched, and a card spring is connected between the card ball and the guide cylinder. When the rotating shaft 31 rotates, the card disk will be driven to rotate. The rotation of the card disk will cause the card hole and the card ball to disengage, and the card ball will move forward, and the card spring will be compressed. When the card ball contacts the card hole of the card disk, under the action of the card spring, the card ball is driven to move and reset to clamp the card disk. The card assembly 36 is used to clamp the rotating shaft 31. Under the action of the card assembly 36, the rotating shaft 31 will only rotate when the rotating shaft 31 is rotated by external force, and when the rotating shaft 31 is rotated without external force, the card assembly 36 keeps the rotating shaft 31 in a state of being clamped. A driving assembly is provided between the dual-axis motor 14 and the rotating shaft 31, and the driving assembly is used to drive the rotating shaft 31 to rotate.

[0041] like Figure 10-11As shown, the driving assembly includes a one-way gear 33, a gear set 34 and a large gear 35. The one-way gear 33 is welded to the lower part of the rotating shaft 31, and the one-way gear 33 is connected to the upper and lower sides of the rotating shaft 31. The left and right sides of the top and the left and right sides of the bottom of the support plate frame 1 are rotatably connected to the gear set 34, and the gear set 34 and the one-way gear 33 are meshed. The two output shaft ends of the dual-axis motor 14 are connected to the large gear 35, and the large gear 35 and the gear set 34 are meshed.

[0042] After the inflation piece 2 is deflated, it becomes flat and floats on the water. The inflation piece 2 is easily spread out due to water force and wind force, which will interfere with the ship's remote-controlled life buoy approaching the person who falls into the water. Therefore, a pressure plate 4 is provided. After the inflation piece 2 is deflated and becomes flat, the return spring 42 in a compressed state drives the slider 43 to move away from the pressure plate 4. The slider 43 pulls the elastic line 41, and the elastic line 41 drives the pressure plate 4 to move toward the floating block 12, thereby making the pressure plate 4 close to the floating block 12. The pressure plate 4 will press the deflated inflation piece 2 against the floating block 12, so that the inflation piece 2 will not interfere with the ship's remote-controlled life buoy approaching the person who falls into the water. When the inflation piece 2 expands and bulges, it will push the pressure plate 4 to move away from the floating block 12. The pressure plate 4 pulls the slider 43 to move through the elastic line 41, and the return spring 42 is compressed.

[0043] like Figure 13-14 As shown, it also includes a pressure plate 4, an elastic cord 41, a return spring 42 and a slider 43. The expansion member 2 is connected to a pressure plate 4 on the side away from the float 12. The pressure plate 4 is used to press the expansion member 2 so that the expansion member 2 is close to the float 12. Two sliders 43 are slidably connected to the float 12. Elastic cords 41 are connected between the sliders 43 and the adjacent pressure plates 4. The elastic cords 41 pass through the float 12 and the expansion member 2 respectively. Reset springs 42 are connected between the sliders 43 and the float 12. The reset springs 42 are wound around the elastic cords 41.

[0044] When the output shaft of the dual-axis motor 14 rotates forward to drive the rope winding wheel 15 to loosen the pull rope 16, the output shaft of the dual-axis motor 14 also drives the large gear 35 to rotate forward at the same time. The forward rotation of the large gear 35 drives the outer gear ring of the one-way gear 33 to rotate idly through the gear set 34, while the inner gear ring of the one-way gear 33 cannot rotate, and the rotating shaft 31 also remains stopped. Under the action of the positioning assembly 36, the rotating shaft 31 can be kept stationary, so that the guide wheel 3 cannot rotate. At this time, when the pull rope 16 is being relaxed, the guide wheel 3 cannot guide the pull rope 16, and the friction groove on the guide wheel 3 will have a deceleration effect on the relaxation of the pull rope 16, allowing the pull rope 16 to slowly loosen the floating block 12. Later, when the output shaft of the dual-axis motor 14 is reversed to drive the rope winding wheel 15 to rewind the pull rope 16, the output shaft of the dual-axis motor 14 The output shaft also drives the large gear 35 to reverse at the same time. The reverse rotation of the large gear 35 drives the one-way gear 33 to rotate through the gear set 34. At this time, the rotation of the one-way gear 33 will drive the two rotating shafts 31 in front to rotate, and the two rotating shafts 31 in the rear are also driven to rotate through the full gear 32, so that the guide wheel 3 rotates to guide the pull rope 16, so that the pull rope 16 can be tightened quickly. After the pull rope 16 is tightened, the dual-axis motor 14 stops working. At this time, under the action of the locking component 36, the rotating shaft 31 can be stuck, so that the guide wheel 3 remains stationary. In this way, if the rope wheel 15 accidentally loosens the pull rope 16, the friction groove on the guide wheel 3 can also limit the friction of the pull rope 16, so as to prevent the floating block 12 from suddenly loosening when the person who falls into the water uses the remote-controlled life buoy for the ship, thereby affecting the rescue.

[0045] like Figure 15-16 As shown, it also includes a lifting frame 5, an oxygen tank 51, a bite block 52 and a socket 53. The lifting frame 5 is slidably connected to the support plate frame 1, and the oxygen tank 51 is clamped on both sides of the lifting frame 5. The socket 53 is fixedly connected to the upper front part of the lifting frame 5, and the bite block 52 is clamped on the front part of the socket 53. The left and right sides of the bite block 52 and the oxygen tank 51 are connected through a connecting pipe.

[0046] The drowning person will struggle after falling into the water, and is prone to hypoxia during the struggle. After getting the remote-controlled life buoy for the ship, the lifting frame 5 can be moved upward by himself, and the bite block 52 can be removed and put on his nose to breathe oxygen. By setting up the oxygen tank 51, oxygen can be provided for the drowning person. When not in use, the bite block 52 is re-inserted into the seat 53, and the lifting frame 5 is moved downward to reset.

[0047] like Fig.17As shown, it also includes a light emitting device 6, which is arranged on the top of the support plate frame 1. The light emitting device 6 and the external control device are electrically connected through a control module. When rescuing at night, the light emitting device 6 can be turned on by the external control device, so that the position of the remote-controlled life buoy of the ship can be observed for rescue. When not in use, the light emitting device 6 is turned off by the external control device.

[0048] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
