Description

Technical Field

[0001] The present invention relates to the technical field of marine launching and retrieving devices, and in particular to a basket-type lifeboat launching and retrieving device suitable for an unmanned ship and a use method thereof. Background Art

[0002] With the rapid development of marine engineering and technology, lifeboats play an indispensable role in marine rescue and become key equipment to ensure the safety of people at sea. Due to the unpredictable marine environment, lifeboats need to be able to be quickly released and recovered while ensuring safety.

[0003] The prior art provides certain solutions. The "a lifeboat retrieval device for ships" disclosed in the Chinese patent document has a publication number of CN116834901A. The lifeboat retrieval device for ships includes a main rod body, a traction assembly and an auxiliary assembly. The four traction wheels provided on the traction assembly are all provided with rope bodies, which can ensure that the lifeboat can still be pulled after any rope body breaks, ensuring the safety of the lifeboat up and down, and the position of the lifeboat can be relatively changed by pulling the second rope body; the auxiliary assembly includes an auxiliary plate, which is an elastic plate. When in contact with the lifeboat, it is a flexible contact. The impact force generated at the moment of contact is small, which protects the operator. Because the auxiliary plate is an elastic plate, it deforms when in contact and can better fit the side of the lifeboat to adapt to different structural shapes. Although the patent method can safely retract and release the lifeboat, it takes a long time to recover when in use, and it is still insufficient in terms of rapidity. The inventor believes that there is still a lot of room for improvement. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to propose a basket-type lifeboat retrieval device and a method of use suitable for an unmanned ship, which can achieve rapid and safe release and recovery of the lifeboat under the drive of the basket device and the rope.

[0005] In order to achieve the above object, the technical solution specifically adopted by the present invention is as follows:

[0006] A basket-type lifeboat retrieval device suitable for an unmanned ship, the basket-type lifeboat retrieval device is symmetrically distributed on both sides of the unmanned ship, and includes a basket device, a retrieval device and a parking device, wherein:

[0007] The hanging basket device comprises two hanging rods, a bottom plate movably connected to the two hanging rods, a flap hinged to the bottom plate, a second electric push rod for realizing the up and down flipping of the bottom plate by telescoping, and a third electric push rod for realizing the left and right flipping of the flap by telescoping;

[0008] The retractable device includes a No. 1 electric push rod, a No. 1 base, a No. 2 base and a support rod, one end of the support rod is connected to the boom through a pin shaft, and the other end is fixedly connected to the deck of the unmanned boat through the No. 2 base, one end of the No. 1 electric push rod is fixedly connected to the deck of the unmanned boat through the No. 1 base, and the other end is hinged to the support rod, and the support rod is rotated by the extension and retraction of the No. 1 electric push rod;

[0009] The parking device includes a No. 1 conveyor and a No. 2 conveyor arranged on the deck of the unmanned ship, and mooring piles located on both sides of the No. 1 conveyor and the No. 2 conveyor. The No. 1 conveyor and the No. 2 conveyor can be used to moor a lifeboat, wherein the No. 1 conveyor includes a set of conveyor belts and pulleys, and the No. 2 conveyor includes two sets of conveyor belts and pulleys, so that the bottom plate can fall smoothly when the lifeboat is recovered. Furthermore, the operation of the No. 1 conveyor and the No. 2 conveyor can transport the lifeboat between the two conveyor devices.

[0010] In a hanging basket type lifeboat retrieval device suitable for an unmanned ship of the present invention, two suspension rods are connected by an upper bracket and a lower bracket, a camera is installed on the upper bracket, which can be used to assist in the release and recovery of the lifeboat and provide relevant images for the staff to judge whether the lifeboat has reached a suitable position, and the lower bracket is connected to the arc groove of the bottom plate.

[0011] In a hanging basket type lifeboat retrieval and launching device suitable for an unmanned ship of the present invention, the hanging basket device further comprises two openable and closable baffles, and the two openable and closable baffles are connected to the suspension rod through hinges.

[0012] In a hanging basket type lifeboat retrieval and launching device suitable for an unmanned ship of the present invention, the bottom plate includes a bottom plate body, a No. 1 boss arranged on one side of the bottom plate body, a limit frame, a cable hole, a reinforcing plate and a No. 2 boss arranged on the front side of the bottom plate body; the flap includes a flap body and a flap boss and a flap cross bar arranged on the front side of the flap body; one end of the No. 2 electric push rod is connected to the hanging rod through a connector, and the other end is connected to the No. 1 boss; one end of the No. 3 electric push rod is connected to the No. 2 boss, and the other end is connected to the flap boss of the flap; driven by the No. 2 electric push rod, the bottom plate can be flipped up and down, and driven by the No. 3 electric push rod, the flap can be flipped left and right, so that the hanging basket device as a whole has a high degree of freedom, and can realize the rapid release and recovery of the lifeboat.

[0013] In a basket-type lifeboat retrieval and launching device suitable for an unmanned ship of the present invention, a No. 3 roller is installed on the limit frame and is fixedly connected to the base plate body, which is used to limit the moving distance of the lifeboat and prevent it from slipping. The reinforcing plate is fixedly installed at the four corners of the base plate body, which can improve the strength of the base plate as a whole and also improve the safety of the retrieval and launching process.

[0014] In a basket-type lifeboat retrieval and launching device suitable for an unmanned ship of the present invention, a first roller and a second roller are installed on the first base and the second base.

[0015] The present invention is a hanging basket type lifeboat retrieval device suitable for unmanned ships, which also includes a cable and a cable retrieval device. The cable is connected to the cable retrieval device and the lifeboat respectively. When the lifeboat is moored on it, the lifeboat can be connected to the mooring pile by the rope to prevent the lifeboat from sliding. Specifically, one end of the cable is connected to the cable retrieval device, and the other end is connected to the lifeboat after passing through the first roller, the second roller, the third roller and the rope hole of the limit frame. Due to the unpredictable marine environment, this connection can ensure the safety of the lifeboat during operation on the one hand, and can also help speed up the recovery of the lifeboat on the other hand.

[0016] In a basket-type lifeboat retrieval and launching device suitable for an unmanned ship of the present invention, the bottom plate and the flap are both hollow structures, which can reduce the overall weight of the retrieval and launching device on the one hand, and can also quickly drain water on the other hand.

[0017] In a basket-type lifeboat retrieval and launching device suitable for an unmanned ship of the present invention, the basket device also includes two openable and closable baffles, which are connected to the suspension rod by hinges. Since the unmanned ship requires a tail propeller to provide power, and the water flow caused by the propeller will affect the retrieval and launching process of the lifeboat, the baffle is used to improve the safety of the retrieval and launching process.

[0018] The present invention also provides a method for using the above-mentioned basket-type lifeboat retrieval device suitable for an unmanned ship, comprising the following steps:

[0019] S1: Install the basket device, the retracting and launching device and the parking device at appropriate positions on the unmanned boat, and moor the two lifeboats on the No. 1 transmission device and the No. 2 transmission device respectively;

[0020] S2: When releasing the lifeboat, start and shorten the No. 1 electric push rod to rotate the support rod, driving the basket device to move toward the stern. Due to gravity and the action of the No. 2 electric push rod, the bottom plate can be kept horizontal. When the bottom plate is completely immersed in water, the lifeboat is separated from the bottom plate. At this time, the lifeboat is released by controlling the lifeboat and releasing the cable;

[0021] S3: After the operation is completed, the lifeboat moves autonomously to the top of the bottom plate. At this time, the No. 2 and No. 3 electric push rods are controlled to lift the lifeboat through the bottom plate and the flap. Then, the No. 1 electric push rod and the cable retracting device are controlled to lift the lifeboat to the deck of the unmanned ship to complete the recovery work.

[0022] The present invention has the following characteristics and beneficial effects:

[0023] 1) The retrieval and launching device of the present invention has a high degree of freedom. On the one hand, the basket device can move as a whole under the drive of the No. 1 electric push rod, and the bottom plate and the flap can be rotated separately under the drive of the No. 2 electric push rod and the No. 3 electric push rod, thereby making the retrieval and launching of the lifeboat more convenient and quick, and with the assistance of the cable, the safety and speed of the retrieval and launching are further guaranteed.

[0024] 2) When the present invention is in the process of folding and releasing, since the lifeboat is always in contact with the bottom plate and the bottom plate is always kept horizontal, the time for dynamically adjusting the posture of the lifeboat can be greatly reduced compared with the lifting type folding and releasing device.

DETAILED DESCRIPTION

[0031] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] like Figure 1-Figure 5As shown, a basket-type lifeboat storage and launching device suitable for unmanned ships that can quickly store and launch lifeboats is provided on an unmanned ship 1, and includes a basket device, a storage and launching device for storing and launching the basket device, and a parking device for parking the basket device. The basket device includes two suspension rods 14, a bottom plate 15, a flap 23, two No. 2 electric push rods 5, and two No. 3 electric push rods 7. The suspension rods 14 are in a "T"-shaped structure. The two suspension rods 14 are symmetrically arranged at both ends of the bottom plate 15. The upper ends are respectively connected to the two support rods 22 through two pin shafts and can rotate relative to each other. Therefore, when the basket device moves under the rotation of the support rods 22, the force balance can be generated by the gravity of the basket device itself and the No. 2 electric push rods 5, so that the bottom plate always remains horizontal when the lifeboat 9 is stored and launched; the lower ends of the two suspension rods 14 cooperate with the arc-shaped grooves of the bottom plate 15 to form a "T"-shaped structure. The two No. 2 electric push rods 5 are symmetrically arranged at both ends of the bottom plate 15, one end of the No. 2 electric push rod 5 is connected to the suspension rod 14 through the connector 13, and the other end is connected to the No. 1 boss 26 of the bottom plate 15, and the two No. 3 electric push rods 7 are symmetrically arranged at both ends of the bottom plate 15, one end is connected to the No. 2 boss 27, and the other end is connected to the flap boss 31 of the flap 23. Driven by the No. 2 electric push rod 5, the bottom plate 15 can be turned upside down, and driven by the No. 3 electric push rod 7, the flap 23 can be turned left and right. Therefore, the retracting and releasing device has a high degree of freedom and can quickly release and recover the lifeboat 9.

[0033] The retracting and releasing device includes an electric push rod 8, a base 3, a base 4 and a support rod 22. One end of the support rod 22 is connected to the suspension rod 14 through a pin shaft, and the other end is fixedly connected to the deck of the unmanned boat 1 through the base 4. One end of the electric push rod 8 is fixedly connected to the deck of the unmanned boat 1 through the base 3, and the other end is hinged to the support rod 22. The support rod 22 is rotated by extending and retracting the electric push rod 8. The base 3 and the electric push rod 8, the electric push rod 8 and the support rod 22, and the support rod 22 and the base 4 are all connected by pin shafts to achieve relative rotation. The support rod 22 is rotated by extending and retracting the electric push rod 8, thereby driving the hanging basket device to move.

[0034] The parking device includes a No. 1 conveying device 10, a No. 2 conveying device 11 and a mooring pile 12 arranged on the deck of the unmanned ship 1. The No. 1 conveying device 10 adopts a combination of a conveyor belt and a pulley, while the No. 2 conveying device 11 adopts a combination of two groups of conveyor belts and pulleys. The purpose of designing two groups is to allow the bottom plate 15 to fall smoothly on the deck. The mooring piles 12 are symmetrically distributed on both sides of the No. 1 conveying device 10 and the No. 2 conveying device 11. The lifeboat 9 can be connected to the mooring piles 12 through a connecting device to fix the lifeboat 9.

[0035] Furthermore, the two booms 14 are connected by an upper bracket 24 and a lower bracket 25 installed in parallel. Both the upper bracket 24 and the lower bracket 25 are in the shape of an arc plus a plane and are fixedly connected to the boom 14. The upper bracket 24 is equipped with a camera 21, which can assist in the release and recovery of the lifeboat 9 and provide relevant images for the staff to judge whether the lifeboat 9 has reached the appropriate position. The lower bracket 25 is connected to the arc groove of the bottom plate 15 by means of the arc shape. The upper plane can improve the connection stability, and the plane shape can increase the connection stability. With the extension and retraction of the No. 2 electric push rod 5, the bottom plate 15 can be turned up and down through this active cooperation. It can be understood that since the basket device needs to move between the deck and the stern of the unmanned ship 1, the "T"-shaped length of the boom 14 needs to be controlled to prevent collision with the unmanned ship 1.

[0036] Furthermore, the basket device also includes two openable and closable baffles 20, which are connected to the boom 14 via hinges. When the basket device is at the stern, the baffles 20 need to be closed, which can partially block the water flow generated by the propeller 19, thereby increasing the safety of the lifeboat 9 when it is folded or released.

[0037] Furthermore, the bottom plate 15 includes a bottom plate body in a frame shape, a No. 1 boss 26 arranged on one side of the bottom plate body, a limit frame 28, a cable hole 29, a reinforcing plate 30 and a No. 2 boss 27 arranged on the front side of the bottom plate body. The limit frame 28 is fixedly connected to the bottom plate body to limit the moving distance of the lifeboat 9 and prevent it from slipping. The reinforcing plate 30 is fixedly installed at the four corners of the bottom plate body to improve the strength of the bottom plate 15 as a whole, thereby further increasing the safety of the present invention.

[0038] Furthermore, the flap 23 includes a flap body, a flap boss 31 and a flap cross bar 32 arranged on the front side of the flap body. The flap cross bar 32 is connected to one side of the bottom plate 15 through a hinge, and relative rotation can be achieved using the hinge.

[0039] Furthermore, the bottom plate 15 and the flap 23 are both hollow designs, which can reduce the overall weight of the hanging basket device and relieve the pressure of each electric push rod on the one hand, and can also quickly discharge the seawater entering the hanging basket device on the other hand.

[0040] Furthermore, a cable retracting device 2 and a cable 17 are also provided on the deck of the unmanned boat 1, and the No. 1 base 3, the No. 2 base 4 and the limit frame 28 are respectively installed with the No. 1 roller 16, the No. 2 roller 18 and the No. 3 roller 6, one end of the cable 17 is connected to the cable retracting device 2, and the other end is connected to the lifeboat 9 after passing through the No. 1 roller 16, the No. 2 roller 18, the No. 3 roller 6 and the cable hole 29. By controlling the release length of the cable 17, the safety of the lifeboat 9 during operation can be improved, and in the recovery stage, the auxiliary effect of the cable 17 can help the lifeboat 9 move to a suitable position above the bottom plate 15 faster.

[0041] It can be understood that the unmanned lifesaving devices of the present invention are symmetrically distributed on both sides of the unmanned boat 1.

[0042] Furthermore, the present invention also provides a method for using a basket-type lifeboat retrieval device suitable for an unmanned ship, and the specific steps are as follows:

[0043] S1: Install the hanging basket device, the retracting device and the parking device at appropriate positions on the unmanned ship 1, and moor the two lifeboats 9 on the No. 1 conveying device 10 and the No. 2 conveying device 11 respectively;

[0044] S2: When releasing the lifeboat 9, the No. 1 electric push rod 8 is started and shortened to rotate the support rod 22. The rotation of the support rod 22 drives the boom 14 to move toward the stern, and then drives the basket device to move toward the stern. Due to gravity and the force balance of the No. 2 electric push rod 5, the bottom plate 15 can always remain horizontal during the operation. When the bottom plate 15 is completely immersed in water, the lifeboat 9 will be separated from the bottom plate 15 due to the buoyancy. At this time, the lifeboat 9 can be released by controlling the lifeboat 9 and releasing the cable 17;

[0045] S3: After the operation is completed, the lifeboat 9 is first moved autonomously to the top of the bottom plate 15 of the hanging basket device. At this time, the No. 2 electric push rod 5 and the No. 3 electric push rod 7 are controlled to make the bottom plate 15 and the flap 23 "scoop" the lifeboat 9 to pick it up, and with the help of the rope, the recovery time can be further shortened. Then, the No. 1 electric push rod 8 is controlled to lift the hanging basket device to the deck of the unmanned ship 1, thus completing the recovery of the lifeboat 9.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
