Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a hull of a semi-submersible garbage salvaging ship and a method for manufacturing and adjusting the structure thereof. Background Art

[0002] In the existing technology, garbage salvage ships generally have the following shortcomings due to their own structural limitations:

[0003] First, salvage vessels are typically designed to be relatively small to meet the need for flexible navigation in river channels. However, small salvage vessels have limited carrying capacity. Once fully salvaged, they must return to the port to unload and then return to the site to continue salvaging. This not only consumes energy but also hinders salvage efficiency (the effective working time for clearing the water surface is severely affected).

[0004] The second reason is that the operating environment of salvage vessels is relatively complex. Unpredictable underwater objects such as hidden piles and rocks can easily impact and damage the hull during the operation of the vessel, resulting in relatively poor safety of salvage vessels.

[0005] The third reason is that the hull has a single function and can only be used to salvage surface garbage;

[0006] Fourthly, when the salvage vessel is underloaded, its passability is poor when encountering river bridges (especially low landscape bridges);

[0007] Therefore, there is a need for a semi-submersible garbage salvage ship hull with relatively large carrying capacity, relatively high operating efficiency, relatively good safety, less external influence on navigation, strong passability, high stability and diverse functions. Summary of the Invention

[0008] The embodiment of the present application solves the technical problems of garbage salvage ships in the prior art, such as small carrying capacity, low operating efficiency, poor safety, poor navigation passability and stability, and single function, by providing a semi-submersible garbage salvage ship hull; and achieves the technical effects of a semi-submersible garbage salvage ship with relatively large carrying capacity, relatively high operating efficiency, relatively good safety, less external influence on navigation, strong passability, high stability, and diverse functions.

[0009] The embodiment of the present application provides a semi-submersible garbage salvage vessel hull, comprising a basic hull, a main buoyancy tank group, an auxiliary buoyancy tank group, and a pump air assembly;

[0010] The basic hull is a long hard shell that plays a bearing and supporting role;

[0011] The main pontoon group includes two main pontoons; the main pontoons are hard, long, closed boxes, and are fixed on both sides of the base hull respectively;

[0012] The auxiliary pontoon group includes a plurality of auxiliary pontoons; the auxiliary pontoons are long strips, open at the bottom, with a pump air connector on the top or one side, and closed at other locations. The number of the auxiliary pontoons is a multiple of 2 and is positioned on the side and / or bottom of the main pontoon;

[0013] The pump air assembly is connected to the pump air connector and is used to adjust the amount of gas in the auxiliary float tank and thus change the buoyancy of the entire hull.

[0014] Preferably, the auxiliary buoyancy tanks are all fixed with built-in air bags, which are connected to the pump air connectors. When the pump air assembly pumps air into the built-in air bags, the built-in air bags expand; and all the pump air connectors are connected to the built-in air bags.

[0015] Preferably, each auxiliary buoyancy tank has multiple built-in air bags.

[0016] Preferably, one or more vertically arranged partition plates are fixed in the auxiliary buoyancy tank;

[0017] The partition plate is a hard plate that divides an auxiliary buoy into multiple cavities with only the bottom open. Each cavity is independently connected to the pump air component through a separate pump air connector. When the hull posture needs to be adjusted, it is achieved by adjusting the amount of gas in the cavity.

[0018] Preferably, a built-in air bag is fixed in each cavity separated by the partition plate, and each built-in air bag is independently connected to the pump air component through a pump air connector; the cavity separated by the partition plate is not connected to the pump air component.

[0019] Furthermore, each auxiliary buoyancy tank has three built-in air bags, namely the front bag, the middle bag and the rear bag;

[0020] Two vertically arranged partition plates are fixed in the auxiliary pontoon, and the two partition plates divide the auxiliary pontoon into two side cavities and a middle cavity;

[0021] The middle capsule is located in the middle cavity.

[0022] Preferably, the bottom of the auxiliary buoyancy tank is completely open;

[0023] The middle bladder is formed by combining and fixing a plurality of plate-shaped bladder units together. The plurality of plate-shaped bladder units are arranged in a row, are all vertically arranged and are in the shape of a long strip as a whole. One end of the middle bladder is fixed to a partition plate close to the front bladder, and the other end is fixed to a contact plate.

[0024] The plate-shaped capsule unit is a plate-shaped capsule body, formed by fixing the edges of two rubber sheets together, which is a rectangular sheet or a round sheet in the contracted state and bulges when inflated;

[0025] A plurality of plate-shaped capsule units are stacked together and fixed at their centers to adjacent plate-shaped capsule units, and the adjacent plate-shaped capsule units are interconnected;

[0026] The contact plate is a hard plate with a U-shaped longitudinal section, fixed to one end of the middle capsule close to the rear capsule and with its opening facing the middle capsule;

[0027] A connecting rope is fixed on the contact plate; the connecting rope is an elastic rubber rope, one end of which is fixed on the contact plate and the other end is fixed on the partition plate close to the posterior capsule, and is always in a straight state;

[0028] A top wedge-shaped capsule is fixed on the top of the middle cavity; when the top wedge-shaped capsule contracts, it is tightly attached to the top of the middle cavity; when it expands, it expands into a wedge shape and squeezes the contact plate and part of the plate-shaped capsule unit out of the middle cavity.

[0029] Preferably, expansion accessories are also included;

[0030] The expansion accessory is in the shape of a plate as a whole, including a base plate, a rotating plate and a limiting plate; the base plate is arranged vertically and plays the role of bearing connection;

[0031] The rotating plate is a hard straight plate, arranged longitudinally, with the top hinged to the bottom of the base plate, and the axial direction of the rotating shaft is the same as the width direction of the base plate;

[0032] The limit plate is a hard plate body, which plays the role of limiting the rotation angle of the rotating plate. It is fixed to the bottom of the base plate and is arranged close to the rotating plate. When the rotating plate rotates to a vertical state, it contacts the rotating plate to limit its further rotation.

[0033] After the expansion accessories are installed, the rotating plate rotates when the middle bag is shortened, and when the middle bag is extended, the rotating plate gradually rotates to a vertical state due to the resistance of the water and the restriction of the limit plate, and pushes the water flow to drive the hull to move;

[0034] When the power components of the hull fail, the operators will detachably fix the base plate to the resistance plate and control the expansion and contraction of the middle bag to use it as temporary power for the hull.

[0035] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0036] By optimizing and improving the structure of the garbage salvage ship in the prior art, a semi-submersible garbage salvage ship hull is provided, which includes a long basic hull, a main pontoon group and an auxiliary pontoon group; the main pontoon group includes two long main pontoons positioned on both sides of the basic hull, the main pontoons are closed boxes and are always in a closed state; the auxiliary pontoon group includes two auxiliary pontoons respectively positioned on the side walls or bottoms of the two main pontoons, the bottoms of the auxiliary pontoons are open, and the internal spaces are connected to the pump air components; the hull of the semi-submersible garbage salvage ship of the present application floats up as a whole when the empty ship is transferred, and changes from a fully floating state to a semi-shallow state after arriving at the operating area, The space inside the auxiliary pontoons is connected to the external waters, and the hull can float and dive by filling or draining water in the two auxiliary pontoons; because it can float and dive as needed, it can not only be used for garbage salvage, but also for other operation scenarios such as emergency operations: it effectively solves the technical problems of garbage salvage ships in the existing technology, such as small carrying capacity, low operating efficiency, poor safety, poor navigation passability and stability, and single function; and thus achieves the technical effect of semi-submersible garbage salvage ships with relatively large carrying capacity, relatively high operating efficiency, relatively good safety, less external influence on navigation, strong passability, high stability and diverse functions.

DETAILED DESCRIPTION

[0050] To facilitate understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0051] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are for illustrative purposes only and do not represent the only implementation method.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0053] Example 1

[0054] like Figures 1 to 4 As shown, the hull of the semi-submersible garbage salvage vessel of the present application includes a basic hull 001, a main buoyancy tank group, an auxiliary buoyancy tank group and a pump air assembly.

[0055] The basic hull 001 is a long hard shell that serves as a load-bearing support. It is equipped with power components, control components, a container warehouse for accommodating garbage, and a solid-liquid separation component for realizing solid-liquid separation of garbage; the power components are used to provide power for the operation of the various components of the hull of the semi-submersible garbage salvage ship of this application, and the control unit plays a role in controlling the coordinated operation of the various components of the hull of the semi-submersible garbage salvage ship of this application; the power components, control components, container warehouse and solid-liquid separation components are all existing technologies and will not be described in detail here.

[0056] The main pontoon group includes two main pontoons 002; the main pontoon 002 is a hard long strip box, the length direction of which is the same as the length direction of the basic hull 001, and the interior is closed. The two main pontoons 002 are respectively fixed on both sides of the basic hull 001 to provide buoyancy for the hull.

[0057] The auxiliary pontoon group includes two auxiliary pontoons 003, which are long hard boxes with the same length direction as the basic hull 001. The bottom is open, and a pump air connector 034 is provided on the top or one side, and the other positions are closed; the two auxiliary pontoons 003 are respectively fixed on the side walls of the two main pontoons 002, and are located on the side of the main pontoon 002 away from the basic hull 001; the pump air connector 034 is a gas connector, which serves to connect with the pump air component.

[0058] The pump air assembly is positioned on the basic hull 001, the main pontoon group and / or the auxiliary pontoon group. It is a combination of an air pump (air source), an air valve and an air pipe. It is connected to the pump air connector 034 and is controlled by the control component to adjust the amount of gas in the auxiliary pontoon 003 and thus change the buoyancy of the entire hull.

[0059] The auxiliary pontoons 003 are all fixed with built-in air bags 004, which are connected to the pump air connectors 034. When the pump air assembly pumps air into the built-in air bags 004, the built-in air bags 004 expand. When the built-in air bags 004 are fully expanded, they will not protrude from the bottom of the auxiliary pontoons 003. All the pump air connectors 034 are connected to the built-in air bags 004. The setting of the built-in air bags 004 and the presence of the auxiliary pontoons 003 and the main pontoons 002 greatly increase the impact resistance of the hull.

[0060] Furthermore, the built-in airbag 004 is an elastic rubber bag, which is a horizontally arranged cylindrical bag.

[0061] Preferably, there are multiple built-in air bags 004 in each auxiliary buoyancy tank 003 .

[0062] Further, such as Figure 3As shown, there are three built-in air bags 004 in each auxiliary buoyancy tank 003, namely the front bag 041, the middle bag 042 and the rear bag 043; the front bag 041, the middle bag 042 and the rear bag 043 are respectively arranged close to the front end, the middle part and the rear end of the hull, and the three are connected to the pump air assembly through independent pump air connectors 034, and can expand and contract independently to adjust the overall posture of the hull, so as to achieve the purpose of changing the center of gravity of the hull and balancing the inclination of the hull caused by the distribution of the load.

[0063] like Figure 4 As shown, further, a boost valve and a pressure relief valve are provided on the air supply pipe of the pump air assembly, and the boost valve and the pressure relief valve are controlled by a control component to control the three states of conduction, disconnection, and deflation between the air supply pipe and the built-in airbag 004; the boost valve and the pressure relief valve form an open-close interlock, with one side open and the other side closed (three states: the pressure relief valve is closed when the boost valve is open, the boost valve is closed when the pressure relief valve is open, and the boost valve and the pressure relief valve are closed at the same time).

[0064] Preferably, the built-in airbag 004 is also connected to a safety valve, and automatically vents (releases excess gas) when the pressure inside the bag is high.

[0065] Preferably, the bottom of the auxiliary pontoon 003 is entirely open (ie, the auxiliary pontoon 003 has no bottom).

[0066] Preferably, the bottom of the auxiliary buoyancy tank 003 is provided with one or more bottom holes 031, and the bottom holes 031 are through holes.

[0067] Preferably, the auxiliary pontoon 003 is coplanar with the bottom surfaces of the main pontoon 002 and the base hull 001.

[0068] Preferably, the two auxiliary pontoons 003 are positioned at the bottom of the two main pontoons 002 respectively.

[0069] Preferably, the number of the auxiliary pontoons 003 is a multiple of 2, and the auxiliary pontoons 003 are positioned on one side and / or the bottom of the main pontoon 002 . The number of the auxiliary pontoons 003 on the two main pontoons 002 is equal and symmetrically arranged.

[0070] Furthermore, due to the existence of the two closed boxes of the main buoyancy box 002, sufficient buoyancy is provided, and even if the basic hull 001 and the auxiliary buoyancy box 003 are filled with water as a whole, the hull will not sink.

[0071] When manufacturing the hull of the semi-submersible garbage salvage ship of this application: it is necessary to install the main pontoon 002 on both sides of the basic hull 001, install the built-in air bag 004 in the auxiliary pontoon 003; then fix the auxiliary pontoon 003 on the main pontoon 002; finally, connect the pump air assembly and the built-in air bag 004.

[0072] The adjustment and control method of the hull of the semi-submersible garbage salvage vessel of the present application is as follows: when the hull is transferred empty, it floats up as a whole; when the vessel reaches the working area, it needs to change from a fully floating state to a semi-submerged state (that is, the amount of gas in the auxiliary buoyancy tank 003 is reduced so that the hull sinks as a whole); during the garbage collection process, as the collected materials (load) increase, the draft increases; during the salvage operation, the amount of gas in the auxiliary buoyancy tank 003 is adjusted so that the load capacity increases accordingly; when loading imbalance occurs, the inflation volume of a single or multiple built-in air bags 004 can be changed to achieve ship balance; when the loading volume reaches the rated value, the salvage operation stops.

[0073] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0074] The invention solves the technical problems in the prior art of garbage salvage ships, such as small carrying capacity, low operating efficiency, poor safety, poor navigation passability and stability, and single function; and achieves the technical effects of a semi-submersible garbage salvage ship with relatively large carrying capacity, relatively high operating efficiency, relatively good safety, less external influence on navigation, strong passability, high stability, and diverse functions.

[0075] Hull load capacity is greatly increased: by changing the gas volume in the auxiliary buoyancy tank 003, the hull load capacity is greatly increased;

[0076] Improved operational efficiency: Due to the load capacity limit of ordinary ships, when the cargo is loaded to a certain amount, the upper limit of the hull load is reached and the cargo must be transshipped or returned; the manpower and material resources consumed are relatively high, resulting in increased costs; the hull of the present application has an increased buoyancy, and the corresponding load capacity will also increase, turning the original two or three transport volumes into one transport volume; and in actual application of the salvage ship (the salvaged objects float on the water), as the cargo load increases, the hull draft increases, and excessive water intake will affect the filtration efficiency and increase energy consumption losses; too little water intake will cause slightly larger garbage to gather at the bow and not enter the cabin, requiring human intervention; therefore, in the later stage of the salvage operation, when the bow sinks due to increased load, the air bags on both sides of the bow can be controlled to raise the bow as a whole, reducing the bow draft; maintaining the stern draft unchanged, thereby increasing the filtration efficiency and indirectly improving operational efficiency.

[0077] Increased safety: The combination of buoyancy tank and flexible airbag provides better protection for the hull when it is hit;

[0078] Increased hull passability: It is a common phenomenon that the water level of inland rivers and lakes is shallow and the bottom of bridges on the river is low, so a single boat is not suitable for large ships to navigate; this application may require the buoyancy adjustment of the hull. When crossing a bridge, water enters the boat, the built-in airbag 004 is emptied, and the boat's draft becomes deeper;

[0079] Improved stability: When cargo is loaded unevenly, ordinary ships will directly tilt, posing a safety hazard and affecting shipping safety. When the hull of the present application is in use, the inflation volume of a single airbag can be increased to achieve secondary balance of the ship, and the adjustment range is large. In actual use, when the cargo loading weight is uneven or the bow load is uneven, inflating one side of the airbag can lift one side of the ship, thereby increasing the stability of the ship.

[0080] It has various functions and can be used for emergency rescue: in the event of floods and other situations, ordinary ships cannot travel on streets and farmlands and cannot be used as disaster relief ships; when the hull of this application needs to travel in shallow waters, the bow floodgate will be closed and all the water in the boat will be drained, and all the built-in air bags 004 will be opened, the hull draft will be minimized, the boat will float as a whole, and it can be used in shallow waters.

[0081] Example 2

[0082] The difference between the hull of the semi-submersible garbage salvage ship in the embodiment of the present application and the hull of the semi-submersible garbage salvage ship in the first embodiment is that: Figure 5 As shown, the built-in air bag 004 is cancelled, and the pump air assembly is directly connected to the auxiliary float tank 003.

[0083] Since the setting of the built-in air bag 004 is cancelled, there is no need to set a safety valve on the pump gas component. When the gas is overfilled, it will be discharged from the bottom of the ship, which is safer and lowers the cost.

[0084] Preferably, one or more vertically arranged partition plates 032 are fixed in the auxiliary pontoon 003; the partition plates 032 are hard plates, which divide an auxiliary pontoon 003 into multiple cavities with only bottom openings, and each cavity is independently connected to the pump air component through a separate pump air connector 034; when the hull posture needs to be adjusted, it is achieved by adjusting the amount of gas in the cavity.

[0085] Preferably, Figure 6 As shown, two vertically arranged partition plates 032 are fixed in the auxiliary pontoon 003, and the two partition plates 032 divide the auxiliary pontoon 003 into two side cavities and a middle cavity 033; the side cavity and the middle cavity 033 are both long strip cavities.

[0086] Example 3

[0087] The difference between the hull of the semi-submersible garbage salvage ship in the embodiment of the present application and the hull of the semi-submersible garbage salvage ship in Example 2 is that: a built-in air bag 004 is fixed in the cavity separated by the partition plate 032, and each built-in air bag 004 is independently connected to the pump air component through the pump air connector 034; the cavity separated by the partition plate 032 is not connected to the pump air component (which can reduce the risk of water entering the pump air component).

[0088] Furthermore, the middle capsule 042 is located in the middle cavity 033 , and the front capsule 041 and the rear capsule 043 are located in the side cavity.

[0089] Example 4

[0090] In order to further improve the practicality and applicability of the present application and increase its functionality, the present embodiment optimizes and improves the structure of the middle bag 042 in the middle cavity 033 on the basis of the third embodiment, so that the hull of the present application still has good moving ability when it is stranded, when it is traveling on the mudflats, and when it is moving in shallow water areas, and there is no need for operators to disembark and push it: Specifically:

[0091] The bottom of the auxiliary buoyancy tank 003 is completely open;

[0092] like Figures 7 to 9 As shown, the middle capsule 042 is formed by a plurality of plate-shaped capsule units 005 fixed together. The plurality of plate-shaped capsule units 005 are arranged in a row, are vertically arranged, and are in the shape of an elongated strip. One end of the middle capsule 042 is fixed to the partition plate 032 near the front capsule 041, and the other end is fixed to the contact plate 052. The end of the middle capsule 042 near the front capsule 041 is connected to the pump air assembly through the pump air connector 034.

[0093] The plate-shaped capsule unit 005 is a plate-shaped capsule body, formed by fixing the edges of two rubber sheets together. In the contracted state, it is a rectangular sheet or a round sheet, and bulges when inflated.

[0094] Multiple plate-shaped capsule units 005 are stacked together and fixed to adjacent plate-shaped capsule units 005 at their center positions. Adjacent plate-shaped capsule units 005 are interconnected. When the pump assembly inflates the middle capsule 042, the middle capsule 042 stretches as a whole.

[0095] The abutment plate 052 is a hard plate with a U-shaped longitudinal section, fixed to one end of the middle capsule 042 close to the rear capsule 043 and opened toward the middle capsule 042, and is used to reduce friction damage to the plate-shaped capsule unit 005 during use;

[0096] A connecting rope 051 is fixed to the contact plate 052; the connecting rope 051 is an elastic rubber rope, one end of which is fixed to the contact plate 052, and the other end is fixed to the partition plate 032 near the rear bladder 043. The connecting rope 051 is always in a straight state and is used to limit the spatial position of the middle bladder 042 and the contact plate 052, preventing them from falling out of the bottom of the auxiliary buoyancy tank 003 due to their own weight.

[0097] A transversely arranged top wedge-shaped bladder 006 is fixed to the top of the middle cavity 033. The top wedge-shaped bladder 006 is a rubber bladder. When it contracts, it is tightly attached to the top of the middle cavity 033. When it expands, it expands into a wedge shape and the part close to the rear bladder 043 has a larger volume. When it expands, it squeezes the resistance plate 052 and part of the plate-shaped bladder unit 005 out of the middle cavity 033. The top wedge-shaped bladder 006 is independently connected to the pump air component and expands and contracts independently under the control of the control component.

[0098] When it is normal to need to control the amount of gas in the middle bag 042, there is no need to control the deformation of the top wedge-shaped bag 006; when the hull of the present application is stranded, sailing on the mudflats, and moving in shallow water areas, if the ability to move is restricted due to the bottom of the ship touching the ground, the middle bag 042 can be controlled to shrink first, and then the top wedge-shaped bag 006 can be controlled to expand, and finally the middle bag 042 can be controlled to expand and extend. At this time, the middle bag 042 is equivalent to the legs of the hull extending from the bottom of the auxiliary buoy 003 and touching the ground, and the hull can be pushed forward without the need for operators to get off the ship.

[0099] Furthermore, in order to improve the grip, the bottom of the resistance plate 052 is densely covered with a plurality of ground-piercing cones 053; the ground-piercing cones 053 are hard cones.

[0100] Preferably, in order to reduce the wear of the top of the plate-shaped capsule unit 005 and the top wedge-shaped capsule 006, reduce the resistance encountered by the middle capsule 042 when it is extended, and extend the service life of the two; a wear-resistant plate 061 is fixed to the bottom of the top wedge-shaped capsule 006; the wear-resistant plate 061 is a horizontally arranged strip-shaped metal sheet, and the top is close to the bottom of the top wedge-shaped capsule 006.

[0101] Preferably, each plate-shaped capsule unit 005 is filled with sponge and is normally in an expanded state.

[0102] Example 5

[0103] In order to improve the flexibility of the hull movement, the hull of the present application is able to not only move forward but also move backward when its mobility is restricted by the bottom of the ship touching the ground; the order of expansion and contraction of the middle bag 042 and the top wedge-shaped bag 006 can be adjusted as needed; when the hull needs to move forward, the operation in Example 4 is performed (first control the middle bag 042 to contract, and then control the top wedge-shaped bag 006 to expand, and finally control the middle bag 042 to expand and extend); when the hull needs to retreat, first control the middle bag 042 to extend, and then control the top wedge-shaped bag 006 to expand, and push the ground spike 053 into the ground by squeezing, and finally control the middle bag 042 to contract, so that the hull retreats.

[0104] Example 6

[0105] In order to further improve the practicality and applicability of the hull of the present application, so that the hull can still temporarily operate in the water when the power components fail, the embodiment of the present application adds an expansion accessory 007 on the basis of the above embodiment; the expansion accessory 007 acts as a paddle and can be detachably mounted on the contact plate 052; specifically:

[0106] like Figure 10 and Figure 11 As shown, the expansion accessory 007 is in the shape of a plate as a whole, including a base plate 071, a rotating plate 072 and a limiting plate 073; the base plate 071 is vertically arranged to play the role of bearing connection;

[0107] The rotating plate 072 is a hard straight plate, arranged longitudinally, with the top hinged to the bottom of the base plate 071, and the axial direction of the rotating shaft is the same as the width direction of the base plate 071;

[0108] The limit plate 073 is a hard plate that limits the rotation angle of the rotating plate 072. It is fixed to the bottom of the base plate 071 and is located close to the rotating plate 072. When the rotating plate 072 rotates to a vertical position, it contacts the rotating plate 072 to limit its further rotation.

[0109] After the expansion accessory 007 is installed, the rotating plate 072 rotates when the middle capsule 042 is shortened (the angle with the base plate 071 is reduced). When the middle capsule 042 is extended, the rotating plate 072 gradually rotates to a vertical state due to the resistance of the water and the limiting effect of the limit plate 073, and pushes the water flow to drive the hull to move.

[0110] When the power components of the hull fail, the operator can detachably fix the base plate 071 to the resistance plate 052 through clips, bolts, etc., and use it as temporary power for the hull by controlling the expansion and contraction of the middle bag 042.

[0111] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. The internal airbags 004 are positioned integrally on both sides of the hull, and for catamarans, can also be located on the bottom. However, in specific implementations, increasing or decreasing the number and volume of auxiliary buoyancy tanks and / or airbags, as well as changing their locations, is within the scope of this disclosure, depending on the size and purpose of the vessel. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this invention are intended to be included within the scope of this disclosure.
