[0002] Ships are important water transportation tools. With the advancement of shipbuilding technology, large ships have gradually emerged. However, ships often encounter bad weather when sailing on the sea. Strong winds and rough waves can cause the ship to shake severely, or even cause the ship to capsize, endangering the lives of the crew. The crew should escape from the ship in time before danger occurs. Most of the existing seafaring ships are equipped with life-saving equipment to save the crew in an emergency. However, such life-saving equipment takes up a large space and is inconvenient to use. In addition, small life-saving equipment cannot withstand strong waves in severe sea conditions and cannot perfectly provide marine rescue in emergency situations. Moreover, when the life-saving equipment is dropped onto the sea surface, it is easy to cause a large shaking under the impact of the waves. At the same time, it is easy to cause deformation and damage under the impact of the waves, thus threatening the personal safety of the crew.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The emergency escape device for ships, through the connection rails and the connection sliders and the positioning shaft rotatably connected to the lifeboat, when the outer shell sinks into the sea, the device floats on the sea under the buoyancy of the floating airbag. At this time, when the waves are large, the sea surface hits the outer shell. When the outer shell is impacted, the connection slider will slide on the connection rail, and the lifeboat can shake back and forth under the support of the positioning shaft. Under the action of the elastic traction rope, the lifeboat can swing slightly inside the outer shell when the outer shell is impacted, thereby consuming energy and buffering the impact, greatly reducing the damage to the device caused by the impact, thereby avoiding damage to the outer shell and the lifeboat, thereby ensuring the personal safety of the escaping crew members, and at the same time, under the dead weight of the fresh water tank and the traction of the elastic traction rope, the swing amplitude of the lifeboat can be small, reducing the discomfort of the escaping crew members, and quickly resetting and stabilizing when the impact disappears.

[0014] 2. The ship uses an emergency escape device. When using the device for escape, the crew can sit inside the seat groove and lock themselves inside the seat groove through the safety buckle, thereby improving their own impact resistance. When the device shakes greatly, they will not directly collide with the device inside the lifeboat, thus ensuring the safety of riding.

[0015] 3. The ship emergency escape device has a floating airbag in an hourglass shape. When the device is in use, the outer shell below the floating airbag enters the sea surface with the floating airbag as the boundary, and the outer shell above the floating airbag is on the sea surface. When waves are generated on the sea surface, the waves will hit the waist position where the floating airbag is recessed, thereby reducing the impact of the waves on the outer shell, thereby protecting the lifeboat and reducing the shaking of the device.

[0022] See also Figure 1-7The present invention provides a technical solution: an emergency escape device for a ship, comprising an outer shell 1, a lifeboat 12 is arranged inside the outer shell 1, two lifting ears 5 are fixedly connected to the outer shell 1, and the two lifting ears 5 are respectively provided with lifting holes 6 for lifting the device; A first sealing door 4 is installed on the outer shell 1 through a hydraulic assembly, a camera 8 is fixedly installed on the outer shell 1, and a second sealing door 13 is also installed on the lifeboat 12 through a hydraulic assembly; The first sealing door 4 and the second sealing door 13 are opened and closed by a hydraulic assembly, and the first sealing door 4 is opened outwards, and the second sealing door 13 is opened inwards. When the first sealing door 4 and the second sealing door 13 are closed, the outer shell 1 and the lifeboat 12 are both in a sealed state, so water penetration can be effectively prevented; The lower part of the outer shell 1 is rotatably connected to a drive shaft 9, on which a drive assembly is arranged, and the drive assembly is used to make the drive shaft 9 rotate, and the drive assembly can be driven by a common servo motor; An installation cabin 10 is fixedly connected to one end of the drive shaft 9 away from the outer shell 1, and a propeller drive mechanism 11 is arranged on the installation cabin 10. The blades of the propeller drive mechanism 11 are located outside the installation cabin 10, and the drive device of the propeller drive mechanism 11 is located inside the installation cabin 10. The drive shaft 9 is rotated by the drive assembly, so when the drive shaft 9 is rotated, the propeller drive mechanism 11 can be rotated at an angle, so when the propeller drive mechanism 11 is started, the position of the propeller drive mechanism 11 can be adjusted according to the required direction of travel, so that the lifesaving device can be moved in all directions through the propeller drive mechanism 11; The outer shell 1 is provided with a protective mechanism for buffering and balancing the lifeboat 12; The outer shell 1 is provided with a mounting groove 2, and a floating airbag 3 is arranged inside the mounting groove 2; When the floating airbag 3 is in the contracted state, it is folded inside the mounting groove 2, and the floating airbag 3 is located in the middle of the outer shell 1, and the floating airbag 3 is in the shape of an hourglass; The floating airbag 3 is connected to the air supply device, which is a common inflation device and is installed inside the outer shell 1; When the device is needed, the floating airbag 3 can be inflated by the air supply device, and the floating airbag 3 gradually expands. At this time, the crew can enter the interior of the lifeboat 12 and lift the device to the sea surface through the lifting equipment on the hull. At this time, the device floats on the sponge under the buoyancy of the floating airbag 3, and the driving direction of the propeller driving mechanism 11 is adjusted by the driving component, so that the device is driven by the propeller driving mechanism 11 to move on the sea surface; By setting the floating airbag 3 in an hourglass shape, when the device is used, the outer shell 1 below the floating airbag 3 enters the sea surface with the floating airbag 3 as the boundary, and the outer shell 1 above the floating airbag 3 is on the sea surface. When waves are generated on the sea surface, the waves will hit the waist position of the floating airbag 3 which is a concave part, thereby reducing the impact of the waves on the outer shell 1, thereby playing the effect of protecting the lifeboat 12 and reducing the shaking of the device; Furthermore, a connecting oxygen supply hole 7 is provided inside the hanging hole 6, and a connecting pipe 14 communicating with the interior is fixedly connected to the lifeboat 12; The connecting pipe 14 is a retractable corrugated pipe, and a valve is provided on one end of the connecting pipe 14 located inside the lifeboat 12; The connecting pipe 14 is fixedly connected to the hanging ear 5, and the connecting pipe 14 is communicated with the connecting oxygen supply hole 7; When the device is needed, the valve on the connecting pipe 14 can be opened according to the sea conditions, so that the connecting pipe 14 is connected to the external space through the oxygen supply hole 7, so that the external air can enter the interior of the lifeboat 12, thereby ensuring the oxygen supply inside the lifeboat 12.

[0023] Furthermore, the protection mechanism includes two connecting slide rails 15 fixedly installed inside the outer shell 1, and the two connecting slide rails 15 are both arc-shaped; The protection mechanism further includes two positioning shafts 29, which are rotatably connected to the surface of the lifeboat 12, and the two positioning shafts 29 are fixedly connected to the connecting sliders 16; The connecting slide rails 15 are provided with connecting slide grooves 28 that are adapted to the connecting sliders 16, and the connecting sliders 16 are slidably connected inside the connecting slide grooves 28; The lower part of the lifeboat 12 is fixedly connected with an arc-shaped fresh water tank 17, and four elastic traction ropes 18 are fixedly connected to the fresh water tank 17, and the other ends of the elastic traction ropes 18 are fixedly connected to the inner wall of the outer shell 1; The fresh water tank 17 is filled with potable fresh water. The fresh water in the fresh water tank 17 serves to counterweight the lifeboat 12, so that the lifeboat 12 is always in a vertical state under the influence of gravity and the action of the elastic traction rope 18, thereby greatly preventing the lifeboat 12 from flipping over. By means of the connecting rail 15 and the connecting slider 16 and the positioning shaft 29 rotatably connected to the lifeboat 12, when the outer shell 1 sinks into the sea, the device floats on the sea under the buoyancy of the floating airbag 3. At this time, when the waves are large, the sea surface hits the outer shell 1, and when the outer shell 1 is impacted, the connecting slider 16 will slide on the connecting rail 15, and the lifeboat 12 can shake back and forth under the support of the positioning shaft 29, and the elastic traction rope 18 can make the lifeboat 1 When the outer shell 1 is impacted, a slight swing occurs inside it, which plays the role of absorbing impact energy and buffering, and can greatly reduce the damage caused by the impact to the device, thereby avoiding damage and deformation of the outer shell 1 and the lifeboat 12, thereby ensuring the personal safety of the escaping crew members. At the same time, under the deadweight of the fresh water tank 17 and the traction of the elastic traction rope 18, the swing amplitude of the lifeboat 12 can be reduced, reducing the discomfort of the escaping crew members, and quickly resetting and stabilizing when the impact disappears.

[0024] Furthermore, a ring-shaped seat ring 19 is fixedly connected to the inner wall of the lifeboat 12, and a seat groove 20 is provided on the seat ring 19; The inner wall of the seat groove 20 is provided with a safety buckle 27; The safety buckle 27 is a safety belt; When using the device for escape, the crew can sit inside the seat groove 20 and lock themselves inside the seat groove 20 through the safety buckle 27, thereby improving their own impact resistance. When the device shakes greatly, they will not directly collide with the device inside the lifeboat 12, thus ensuring riding safety.

[0025] Furthermore, a function column 21 is fixedly connected to the interior of the lifeboat 12, and a display screen 22 and a control button 23 are rotatably connected to the upper end of the function column 21; The display screen 22 is wirelessly connected to the camera 8, and the control button 23 is electrically connected to the power equipment of the device; The display screen 22 can be used to observe the external sea surface conditions in real time through the camera 8, and the start and shut down of the electrical equipment installed in the device can be controlled by the control button 23. By arranging the function column 21 inside the lifeboat 12, it is convenient for the crew to operate the device when escaping.

[0026] Furthermore, a heater 26 is provided on the function column 21, and a storage drawer 24 is slidably connected to the function column 21; A suction pipe 25 is slidably connected to the functional column 21, and the suction pipe 25 is connected to the fresh water tank 17. A one-way valve is arranged on the suction pipe 25. When the suction pipe 25 generates a large suction force, the one-way valve opens, so that the water inside the fresh water tank 17 is sprayed out through the suction pipe 25. The storage drawer 24 can be used to store life-saving materials. The number of faces of the functional column 21 is equal to the number of the seat slots 20 and they are arranged opposite to each other, and each face of the functional column 21 is provided with a storage drawer 24 and a straw 25; The heater 26 can be used to heat the lifeboat 12, and the lifesaving supplies in the storage drawer 24 and the connection of the straw 25 with the fresh water tank 17 can provide the crew with daily food and fresh water, thereby increasing the survival time on the sea, thereby extending the time waiting for rescue and increasing the chance of survival.

[0027] Working principle: When the device is needed, the floating airbag 3 can be inflated through the air supply device, and the floating airbag 3 gradually expands. At this time, the crew can enter the interior of the lifeboat 12 and lift the device to the sea surface through the lifting equipment on the hull. At this time, the device floats on the sponge under the buoyancy of the floating airbag 3, and the driving direction of the propeller driving mechanism 11 is adjusted through the driving component, so that the device is driven by the propeller driving mechanism 11 to move on the sea surface; By means of the connecting rail 15 and the connecting slider 16 and the positioning shaft 29 rotatably connected to the lifeboat 12, when the outer shell 1 sinks into the sea, the device floats on the sea under the buoyancy of the floating airbag 3. At this time, when the waves are large, the sea surface hits the outer shell 1, and when the outer shell 1 is impacted, the connecting slider 16 will slide on the connecting rail 15, and the lifeboat 12 can shake back and forth under the support of the positioning shaft 29, and the elastic traction rope 18 can make the lifeboat 1 When the outer shell 1 is impacted, a slight swing occurs inside it, which plays the role of absorbing impact energy and buffering, and can greatly reduce the damage caused by the impact to the device, thereby avoiding damage and deformation of the outer shell 1 and the lifeboat 12, thereby ensuring the personal safety of the escaping crew members. At the same time, under the deadweight of the fresh water tank 17 and the traction of the elastic traction rope 18, the swing amplitude of the lifeboat 12 can be reduced, reducing the discomfort of the escaping crew members, and quickly resetting and stabilizing when the impact disappears.
