Description

Technical Field

[0001] This application relates to the technical field of salvage vessels, and more particularly, to an amphibious vessel for salvaging large floating objects. Background Art

[0002] Large floating objects may appear in the open ocean surface, intertidal shallows, reefs, etc. To successfully salvage large floating objects in the above areas, an amphibious vessel for salvaging large floating objects is usually used to salvage large floating objects.

[0003] Chinese Patent Publication No.: CN207374616U discloses a large floating object marine recovery equipment, including a rescue and salvage vessel, the rescue and salvage vessel uses a telescopic crane, a large floating object seat frame, and front and rear tensioning devices; the telescopic crane extends to the side and can rotate, and the large floating object seat frame is within the radius range of the telescopic crane; a salvage interception arm, an oil cylinder, and an inclination sensor are provided on the telescopic crane, and the control center controls the telescopic of the oil cylinder according to the inclination parameter of the inclination sensor, so as to compensate the levelness of the salvage interception arm according to the roll of the hull; an anti-rolling device is suspended below the salvage interception arm; a net is suspended below the salvage interception arm. This application uses a passive compensation device composed of a compensation oil cylinder, an accumulator, and a gas cylinder group to effectively reduce the influence of the hull sinking on the trawl, improve the net shape, and the energy consumption of this compensation device is small; use externally controlled hydraulic oil to open the rotary brake device, so that the interception arm is in a relatively floating state in the horizontal direction, greatly improving the stress state of the interception arm under bad sea conditions.

[0004] Traditional salvage vessels usually adopt a single propeller propulsion method, which is inconvenient to adapt to shallow waters and complex terrains, restricting the salvage range;

[0005] The salvage structure of traditional salvage vessels is single. For example, in the above case, a trawl is used to salvage large floating objects. Since the trawl material is relatively soft, after the large floating object is lifted up, it is easy to cause the large floating object to tilt, thus posing a safety problem for the staff inside the large floating object. And because the large floating object has a certain weight, it is easy to fall during the upward lifting process;

[0006] Secondly, the traditional salvage method blocks the side doors and top doors of large floating objects, affecting the cabin exit of the internal staff. Summary of the Invention

[0007] The present application aims to at least solve the problem of the single salvage structure of traditional salvage ships in the prior art. For example, in the above case, a trawl is used to salvage large floating objects. Since the trawl is made of a relatively soft material, it is easy to cause the large floating objects to tilt after lifting them upwards, thereby causing safety problems for the personnel inside the large floating objects. Moreover, since large floating objects have a certain weight, they are easy to fall during the process of being lifted upwards. Secondly, the traditional salvage method blocks the side doors and top doors of large floating objects, affecting the internal personnel from leaving the cabin. For this reason, the present application proposes an amphibious ship for salvaging large floating objects.

[0008] To achieve the above-mentioned purpose, the present invention provides an amphibious ship for salvaging large floating objects, comprising a hull, an intercepting mechanism, a righting mechanism, a lifting mechanism and a seat frame mechanism, wherein two panels are connected together to form a catamaran hull with only a middle and rear deck, a set of crawler walking devices are respectively arranged at the front and rear parts of the outer side of each panel, and a fully rotating rudder propeller is arranged at the tail end of each panel;

[0009] The interception mechanism comprises two interception arms movably mounted at the front end of the sheet body, and a detection and feedback mechanism is mounted on the interception arms;

[0011] The lifting mechanism comprises a lifting frame spanning between the two sheet bodies, a winch is installed on the top of the lifting frame, a sling is connected to the rope body wound up by the winch, and a hook is installed at the lower end of the sling;

[0012] The seat frame mechanism comprises a seat frame body, the seat frame body is located on the upper side of the support arm, the support arm slides on the bottom of the seat frame body, and the support arm is automatically moved by the seat moving mechanism.

[0013] Furthermore, a radiation claw is hung on the hook.

[0014] Furthermore, the middle and rear parts of the two sheets are connected as a whole through a connecting bridge, and an exit frame is provided in front of the front edge of the connecting bridge, and the two side legs of the exit frame are respectively arranged on the decks of the two sheets.

[0015] Furthermore, the exit frame is located at the rear side of the lifting frame, and an exit port is opened at the top of the exit frame.

[0016] Furthermore, the two intercepting arms are opened and closed respectively by two hydraulic push rods.

[0017] Furthermore, the support arm is extended and retracted by two sets of hydraulic push rods three provided in the seat moving mechanism, and the two sets of hydraulic push rods three are symmetrically arranged at the lower part of the inner side of the two plates.

[0018] Furthermore, two hydraulic push rods are symmetrically installed on the decks of the two sheet bodies, and a locking rod is arranged at the piston end of the two hydraulic push rods.

[0019] Furthermore, the seat frame is driven by four hydraulic push rods, and the four hydraulic push rods are respectively arranged on the inner sides of the two plates.

[0020] Furthermore, a contraction groove is provided at the tail end of the sheet body, and a cylinder is installed in the contraction groove, and the cylinder realizes the extension and retraction of the full-rotation rudder propeller.

[0021] The beneficial effects of the present application are as follows: by installing a crawler walking device and a fully rotating rudder propeller on the hull, the hull can be switched according to the depth of the traveling waters, thereby expanding the use range of the hull; an intercepting mechanism is used to intercept the object to be salvaged to prevent the object to be salvaged from drifting with the water flow, thereby improving the efficiency and safety of salvage; the righting mechanism first drags the bottom of the object to be salvaged, and rights the upper end of the object to be salvaged so that the object to be salvaged is directly under the lifting mechanism, which is convenient for the lifting mechanism to lift it; the frame mechanism supports the bottom of the lifted object and then withdraws the lifting mechanism. This design not only keeps the object to be salvaged stable during the salvage process and prevents the object from falling, but also facilitates the staff in the object to come out from the top, thereby improving the rescue efficiency; through the coordinated work of the intercepting mechanism, the righting mechanism, the lifting mechanism and the frame mechanism, efficient and safe salvage is achieved. This design not only improves the efficiency and safety of salvage, but also enhances the stability and controllability of the hull, reduces maintenance costs, and improves user experience.

[0057] The following describes an amphibious ship for salvaging large floating objects according to an embodiment of the present application with reference to the drawings.

[0058] Embodiment 1

[0059] like Figures 1 - 23 As shown, according to an embodiment of the present application, an amphibious vessel for salvaging large floating objects includes a hull, an intercepting mechanism, a righting mechanism, a lifting mechanism and a seat frame mechanism. Two panels 1 are combined and connected to form a catamaran hull with only a middle and rear deck. The middle and rear parts of the two panels 1 are connected as a whole through a connecting bridge. An exit frame 4 is provided in front of the front edge of the connecting bridge. The two side legs of the exit frame 4 are respectively arranged on the decks of the two panels 1. The exit frame 4 is used for the staff inside the large floating objects to exit the cabin.

[0060] like Figure 1 As shown, a set of crawler walking devices 2 are respectively arranged at the front and rear parts of the outer side of each sheet body 1, and a full-rotation rudder propeller 3 is arranged at the tail end of each sheet body 1; a contraction groove 14 is opened at the tail end of the sheet body 1, and a cylinder 15 is installed in the contraction groove 14, and the cylinder 15 realizes the extension and contraction of the full-rotation rudder propeller 3. When salvaging on the sea surface, the hull is moved out of the land warehouse through the crawler walking device 2. When the hull travels to the shallow water area of the intertidal zone and the average draft has not reached the designed waterline, the hull is subjected to considerable buoyancy, but when the bottom of the crawler walking device 2 has not yet left the ground, due to Due to the effect of buoyancy, the grip of the crawler walking device 2 is weakened, which is not conducive to walking. At this time, seawater can be injected into the ballast tank in the ship to appropriately offset part of the buoyancy, thereby ensuring the grip of the crawler walking device 2, which is conducive to walking. When the hull continues to move forward to the deep water area, under the effect of buoyancy, the crawler walking device 2 is completely separated from the ground. At this time, the ballast seawater is discharged, and the hull propulsion system is switched from the crawler walking device 2 to the rudder propulsion device, that is, the cylinder 15 pushes the full-revolving rudder propeller 3 out of the contraction groove 14, and the full-revolving rudder propeller 3 pushes the hull forward.

[0061] like Figure 3 As shown, the interception mechanism includes two interception arms 10 movably installed at the front end of the sheet body 1, and a detection and feedback mechanism is installed on the interception arm 10. The detection and feedback mechanism can use ultrasonic sensors, infrared sensors and laser radars to detect obstacles in front to prevent the interception arm 10 from hitting floating objects. The two interception arms 10 are opened and closed by two hydraulic push rods 11 respectively. During the forward movement of the above-mentioned hull, the interception arm 10 is in a closed state. When the hull sails to the operating area and finds large floating objects floating on the sea surface, the interception arm 10 is opened. The two interception arms 10 are opened to the outside of the sheet body 1. At this time, the hull continues to move toward the large floating objects. After the large floating objects completely enter the line connecting the front ends of the two fully opened interception arms 10, the two interception arms 10 are gradually closed, and the hull slows down.

[0062] Specifically, Figures 9 - 13 As shown, an amphibious vessel for salvaging large floating objects is docked at the target object and is waiting to be salvaged.

[0063] like Figure 4 and Figure 8As shown in the figure, the righting mechanism includes a support arm 16 located between two sheets 1. The support arm 16 is used to support the bottom of the object to be salvaged. The support arm 16 is telescoped by two sets of hydraulic push rods III 17 provided by the seat moving mechanism. The two sets of hydraulic push rods III 17 are symmetrically arranged at the lower part of the inner sides of the two sheets 1 and are located below the designed waterline. When the hull travels to a suitable area, the lifting frame 5 is positioned above the large floating object. At this time, the support arm 16 extends under the action of the hydraulic push rod III 17 and supports the bottom of the large floating object. Since the hydraulic push rods II 12 are symmetrically installed on the decks of the two sheets 1, a clamping rod 13 is provided at the piston end of the hydraulic push rod II 12. At the same time, the hydraulic push rod II 12 pushes the clamping rod 13 to extend. The extending length of the clamping rod 13 is controlled by the hull operator, so as to realize the righting of the large floating object. Under the telescopic adjustment of the support arm 16 and the clamping rod 13, the righted large floating object is made to face the hook 8 of the lifting frame 5. Secondly, the seat moving mechanism further includes a hydraulic push rod IV 19.

[0064] As Figure 5 and Figure 7 shown in the figure, the lifting mechanism includes a lifting frame 5 spanning between two sheets 1. A winch 6 is installed at the top of the lifting frame 5. A sling 7 is connected to the rope body wound by the winch 6. A hook 8 is installed at the lower end of the sling 7. The hook 8 is lowered, and the radiation lifting claws 9 suspended under the hook 8 extend. Each radiation lifting claw 9 grabs a lifting ring at the top of the large floating object. Then the clamping rod 13 retracts to its original position. The winch 6 is started, and the large floating object rises as the hook 8 rises. Then the support arm 16 retracts to its original position.

[0065] Specifically, as Figures 14 - 18 shown in the figure, it is the lifting state after the amphibious ship salvaging the large floating object salvages the target object;

[0066] As Figure 4 and Figure 8 shown in the figure, the seat mechanism includes a seat body 18. The seat body 18 is located above the support arm 16. The support arm 16 slides on the bottom of the seat body 18. The seat body 18 is driven by a hydraulic push rod IV 19. The hydraulic push rod IV 19 is arranged on the inner sides of the two sheets 1. The hatch frame 4 is located at the rear side of the lifting frame 5. While the support arm 16 retracts, the seat body 18 extends forward under the action of the hydraulic push rod IV 19 to directly below the large floating object, supports and locks the large floating object. Then the radiation lifting claws 9 are unlocked and retracted from the lifting rings of the large floating object. Then the hydraulic push rod IV 19 drives the seat body 18 to retract, so that the large floating object is just carried by the seat body 18 to directly below the hatch frame 4.

[0067] And an exit hatch 20 is opened at the top of the hatch frame 4. The ship's personnel can either stand in front of the connecting bridge deck and open the side door of the large floating object, or board the hatch frame 4 and open the top door of the large floating object to allow personnel to exit the cabin. The personnel can enter the upper end of the hatch frame 4 through the exit hatch 20.

[0068] Specifically, as Figures 19 - 23 shown, it is the state of the amphibious ship for salvaging large floating objects after completing the salvage of the target object and leaving the cabin.

[0069] Embodiment 2

[0070] Considering that large floating objects may land in different sea areas, when salvaging in the shallow water area of the intertidal zone, since most of the large floating objects are exposed above the water surface and in an upright state at this time, the operation method is as follows:

[0071] The hull is moved out of the land storage by the crawler walking device 2. When the hull travels to the shallow water area of the intertidal zone and the average draft has not reached the designed water line, the hull receives a considerable buoyancy, but when the bottom of the crawler walking device 2 has not yet left the ground, due to the buoyancy effect, the gripping force of the crawler walking device 2 is weakened and it is not conducive to walking. At this time, seawater can be injected into the ballast tank of the ship to appropriately offset part of the buoyancy, so as to ensure the gripping ability of the crawler walking device 2 and thus facilitate walking.

[0072] During the above forward process, the interception arm 10 is in the closed state. When the hull sails to the operation area and a standing large floating object is found, the interception arm 10 is opened. The two interception arms 10 open outward to the outside of the sheet body 1. At this time, the hull continues to move forward towards the large floating object. After the large floating object completely enters within the front connection line of the two fully opened interception arms 10, the two interception arms 10 gradually close, and at this time the hull slows down and moves slowly.

[0073] When the hull travels to a suitable area so that the lifting frame 5 is located above the large floating object, the lifting hook 8 is lowered, and the radiation lifting claws 9 suspended under the lifting hook 8 extend. Each radiation lifting claw 9 grabs a lifting ring on the top of the large floating object, and then the positioning rod 13 retracts to its original position. The winch 6 is started, and the large floating object rises as the lifting hook 8 rises;

[0074] The seat frame body 18 extends forward directly below the large floating object under the action of the hydraulic push rod four 19, supports the large floating object, and locks the large floating object. Then the radiation lifting claws 9 are unlocked and retracted from the lifting rings of the large floating object. Then the seat frame body 18 retracts to its original position with the large floating object. At this time, the large floating object is just brought by the seat frame body 18 directly below the hatch frame 4. The personnel on the ship either stand in front of the connecting bridge deck and open the side door of the large floating object, or board the hatch frame 4 and open the top door of the large floating object for personnel to leave the cabin.

[0075] Embodiment 3

[0076] When salvaging in the intertidal beach area, since the large floating object is in an upright state and in a waterless area at this time, the operation method is as follows:

[0077] The hull sails out of the land storage. At this time, it is the crawler travel device 2 that propels the hull forward. Compared with the wheeled travel system, the crawler travel system has a larger contact area with the beach and is not easily stuck in the beach. During the above forward movement, the interception arm 10 is in the closed state. When the hull sails to the operation area and discovers an upright large floating object, the interception arm 10 is opened. The two interception arms 10 open outward to the outside of the sheet body 1. At this time, the hull continues to move forward towards the large floating object. After the large floating object completely enters within the front-end connection line of the two fully opened interception arms 10, the two interception arms 10 gradually close, and at this time the hull decelerates and moves slowly.

[0078] When the hull travels to a suitable area so that the lifting frame 5 is located above the large floating object, the lifting hook 8 is lowered, and the radiation lifting claws 9 suspended under the lifting hook 8 extend. Each radiation lifting claw 9 grabs a lifting ring at the top of the large floating object, and then the positioning rod 13 retracts to its original position. The winch 6 is started, and the large floating object rises as the lifting hook 8 rises;

[0079] The seat frame body 18 extends forward under the action of the hydraulic push rod four 19 directly below the large floating object, supports the large floating object, and locks the large floating object. Then the radiation lifting claws 9 are unlocked and retracted from the lifting rings of the large floating object. Then the seat frame body 18 retracts to its original position with the large floating object. At this time, the large floating object is just brought by the seat frame body 18 directly below the hatch frame 4. The crew on the ship either stands in front of the connecting bridge deck to open the side door of the large floating object or boards the hatch frame 4 to open the top door of the large floating object for personnel to leave the cabin.

[0080] Embodiment Four

[0081] When salvaging at the reef, at this time the large floating object is located on the reef, half exposed above the water and close to the upright state. The operation method is as follows:

[0082] The hull is moved out of the land storage through the crawler travel device 2. When the hull travels to the shallow water area of the intertidal zone and the average draft has not reached the designed water line, the hull receives a considerable buoyancy force. But when the bottom of the crawler travel device 2 has not yet left the ground, due to the buoyancy force, the ground gripping force of the crawler travel device 2 is weakened, which is not conducive to walking. At this time, seawater can be injected into the ballast tank of the ship to appropriately offset part of the buoyancy force, so as to ensure the ground gripping ability of the crawler travel device 2. When the hull continues to move forward to the deep water area and the crawler travel device 2 completely leaves the ground under the buoyancy force, at this time, the ballasted seawater is discharged, and the hull propulsion system is switched from the crawler travel device 2 to the rudder and propeller propulsion device, and the hull is propelled forward by the full-rotation rudder and propeller 3.

[0083] During the above forward movement, the interception arm 10 is in the closed state. When the hull sails to the operation area and a large floating object floating on the sea surface is found, the interception arm 10 is opened. A detection and feedback mechanism is installed on the interception arm 10 to detect obstacles ahead, so as to prevent the interception arm 10 from hitting the floating object. The two interception arms 10 open towards the outside of the sheet body 1. At this time, the hull continues to move forward towards the large floating object. When it sails to a suitable position, the hull stops moving forward. The frogman enters the water with an automatic inflation airbag ring equipped with a rope. The other end of the rope is connected to the hull winch. The frogman climbs onto the reef and puts the airbag ring on the large floating object. The airbag ring slides to the bottom of the large floating object, and then the airbag automatically inflates, so that the large floating object floats up, breaks away from the reef, starts the winch, drags the rope, drives the large floating object to gradually leave the reef and its attached shallow water area, and enters the operation area where the hull can carry out sea salvage; the frogman cuts off the rope and the airbag ring.

[0084] After the hull slowly moves forward and the large floating object completely enters within the front connection line of the fully opened interception arm 10, the two interception arms 10 gradually close, the lifting hook 8 is lowered, and the radiation lifting claws 9 suspended under the lifting hook 8 extend. Each radiation lifting claw 9 grabs a lifting ring on the top of the large floating object, and then the clamping rod 13 retracts to its original position. The winch 6 is started, and the large floating object rises as the lifting hook 8 rises;

[0085] The seat frame body 18 extends forward directly below the large floating object under the action of the hydraulic push rod four 19 provided in the seat frame moving mechanism, supports the large floating object, and locks the large floating object. Then the radiation lifting claws 9 are unlocked and retracted from the lifting rings of the large floating object. Then the seat frame body 18 retracts to its original position with the large floating object. At this time, the large floating object is just brought by the seat frame body 18 directly below the hatch frame 4. The crew on the ship either stands in front of the connecting bridge deck and opens the side door of the large floating object, or climbs onto the hatch frame 4 and opens the top door of the large floating object for personnel to leave the cabin.
