Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and particularly relates to a semi-submersible garbage collection ship hull and a method for manufacturing and adjusting its structure and control. Background Art

[0002] With the development of society, there are more and more floating objects on the water surface. If the floating objects are not cleaned for a long time, it will seriously affect the water environment. In order to cope with the current situation that a large area of floating garbage on the water surface needs to be cleaned, garbage collection ships have been invented and gradually optimized to reduce the labor intensity of operators and improve the operation efficiency.

[0003] In the prior art, due to limitations in their own structures, garbage collection ships generally have the following deficiencies:

[0004] Firstly, in order to meet the need to flexibly navigate in the river, the collection ship is generally designed to be relatively small in volume. However, the load capacity of a small-volume collection ship is relatively limited. After being filled with garbage, it needs to return to the port to unload the goods and then return to the scene to continue the collection, which not only consumes energy but also hinders the collection efficiency (the effective working time for cleaning the water surface will be seriously affected).

[0005] Secondly, the operation environment of the collection ship is relatively complex. Underwater unpredictable objects such as underwater piles and stones are likely to impact and damage the hull during the hull's navigation, resulting in relatively poor safety of the collection ship.

[0006] Thirdly, the hull has a single function and can only be used to collect floating garbage on the water surface.

[0007] Fourthly, when the collection ship has a small load, its passing ability is relatively poor when encountering river bridges (especially low landscape bridges).

[0008] Therefore, there is a need for a semi-submersible garbage collection ship hull with a relatively large load capacity, relatively high operation efficiency, relatively good safety, less affected by the outside world during navigation, strong passing ability, high stability, and diverse functions. Summary of the Invention

[0009] By providing a semi-submersible garbage collection ship hull in an embodiment of the present application, the technical problems in the prior art, such as small load capacity, low operation efficiency, poor safety, poor navigation passing ability and stability, and single function of garbage collection ships, are solved; and the technical effects of the semi-submersible garbage collection ship with a relatively large load capacity, relatively high operation efficiency, relatively good safety, less affected by the outside world during navigation, strong passing ability, high stability, and diverse functions are achieved.

[0010] An embodiment of the present application provides a semi-submersible garbage collection ship hull, including a basic hull, a main floating box group, an auxiliary floating box group, and a gas pumping assembly;

[0011] The basic hull is a long hard shell that plays a bearing and supporting role;

[0012] The main pontoon group includes two main pontoons; the main pontoons are hard and long strip-shaped boxes, which are closed inside and fixed on both sides of the basic hull respectively;

[0013] The auxiliary pontoon group includes a plurality of auxiliary pontoons; the auxiliary pontoons are long strips, open at the bottom, provided with a pump air connector at the top or one side, and closed at other positions, and the number is a multiple of 2, and is positioned on the side and / or bottom of the main pontoon;

[0014] The pump air assembly is communicated with the pump air connector and is used to adjust the amount of gas in the auxiliary buoyancy box and thus change the buoyancy of the entire hull.

[0015] Preferably, a built-in airbag is fixed in each of the auxiliary buoyancy boxes, and the built-in airbag is connected to a pump air connector. When the pump air component pumps air into the built-in airbag, the built-in airbag expands; and all the pump air connectors are connected to the built-in airbag.

[0016] Preferably, each auxiliary buoyancy tank has a plurality of built-in air bags.

[0017] Preferably, one or more vertically arranged partition plates are fixed in the auxiliary buoyancy tank;

[0018] The partition plate is a hard plate that divides an auxiliary buoy into multiple cavities with only the bottom opening. 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.

[0019] 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.

[0020] Furthermore, each auxiliary buoyancy tank has three built-in air bags, namely, a front bag, a middle bag and a rear bag;

[0021] 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;

[0022] The middle capsule is located in the middle cavity.

[0023] Preferably, the bottom of the auxiliary buoyancy tank is completely open;

[0024] The middle capsule is formed by combining and fixing a plurality of plate-shaped capsule units together. The plurality of plate-shaped capsule units are arranged in a row, are vertically arranged, and are in a long strip shape as a whole. One end of the middle capsule is fixed to a partition plate close to the front capsule, and the other end is fixed to a contact plate.

[0025] The plate-shaped bladder unit is a plate-shaped bladder body formed by fixing the edges of two rubber sheets together. In the contracted state, it is a rectangular sheet or a circular sheet, and it bulges when inflated.

[0026] Multiple plate-shaped bladder units are stacked together and fixed at the central position with adjacent plate-shaped bladder units, and the adjacent plate-shaped bladder units communicate with each other.

[0027] The abutting plate is a rigid plate body with a U-shaped longitudinal section, fixed at one end of the middle bladder close to the rear bladder and opening towards the middle bladder.

[0028] A connecting rope is fixed on the abutting plate; the connecting rope is an elastic rubber rope, one end is fixed on the abutting plate, and the other end is fixed on the partition plate close to the rear bladder, and it is always in a taut state.

[0029] A top wedge-shaped bladder is fixed at the top of the middle cavity; when the top wedge-shaped bladder contracts, it clings to the top of the middle cavity, and when it expands, it expands into a wedge shape and extrudes the abutting plate and part of the plate-shaped bladder units out of the middle cavity.

[0030] Preferably, it further includes an expansion accessory.

[0031] The expansion accessory is integrally plate-shaped and includes a base plate, a rotating plate, and a limiting plate; the base plate is vertically arranged and plays a role in bearing and connecting.

[0032] The rotating plate is a rigid straight plate, longitudinally arranged, and its top is 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.

[0033] The limiting plate is a rigid plate body, which plays a role in restricting the rotation angle of the rotating plate, is fixed at the bottom of the base plate and is arranged close to the rotating plate; when the rotating plate rotates to the vertical state, it abuts against the rotating plate to restrict its further rotation.

[0034] After installing the expansion accessory, when the middle bladder shortens, the rotating plate rotates. When the middle bladder elongates, due to the resistance of water and the limiting effect of the limiting plate, the rotating plate gradually rotates to the vertical state and pushes the water flow to drive the hull to move.

[0035] When the power component of the hull fails, the operator can detachably fix the base plate on the abutting plate and use the expansion and contraction of the middle bladder as the temporary power of the hull.

[0036] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0037] By optimizing and improving the structure of the garbage salvage ship in the prior art, a semi-submersible garbage salvage ship hull including a long strip-shaped basic hull, a main floating box group and an auxiliary floating box group is provided; the main floating box group includes two long strip-shaped main floating boxes positioned on both sides of the basic hull, and the main floating box is a closed box body and is always in a closed state; the auxiliary floating box group includes two auxiliary floating boxes respectively positioned on the side walls or bottoms of the two main floating boxes, the bottom of the auxiliary floating box is open, and the internal space is communicated with the air pumping assembly; when the semi-submersible garbage salvage ship hull of the present application is transferred empty, it floats up as a whole, and after reaching the operation area, it changes from the fully floating state to the semi-shallow state. The space inside the auxiliary floating box is communicated with the outside water area, and the hull floats up and dives by filling or discharging the water in the two auxiliary floating boxes; because it can float up and dive as needed, it can not only be used for garbage salvage, but also for other operation scenarios such as emergency rescue operations: effectively solving the technical problems of small load capacity, low operation efficiency, poor safety, poor navigation passability and stability and single function of the garbage salvage ship in the prior art; furthermore, achieving the technical effects of relatively large load capacity, relatively high operation efficiency, relatively good safety, less influence from the outside during navigation, strong passability, high stability and diverse functions of the semi-submersible garbage salvage ship.

[0054] Embodiment 1

[0055] As Figures 1 to 4 shown, the hull of the semi-submersible garbage salvage ship of the present application includes a basic hull 001, a main floating box group, an auxiliary floating box group and a pump gas assembly.

[0056] The basic hull 001 is a long hard shell that plays a bearing and supporting role. It is equipped with power components, control components, a container bin for containing 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 various components of the hull of the semi-submersible garbage salvage ship of the present application, and the control unit plays a role in controlling the coordinated operation of various components of the hull of the semi-submersible garbage salvage ship of the present application; the power components, control components, container bins and solid-liquid separation components are all existing technologies and will not be described in detail here.

[0057] The main pontoon group includes two main pontoons 002; the main pontoons 002 are hard long strip boxes, the length direction of which is the same as the length direction of the basic hull 001, and the inside is closed. The two main pontoons 002 are respectively fixed on both sides of the basic hull 001 to provide buoyancy for the hull.

[0058] The auxiliary pontoon group includes two auxiliary pontoons 003, which are long hard boxes with the same length direction as the basic hull 001, an open bottom, a pump air connector 034 on the top or one side, and other positions 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 pontoons 002 away from the basic hull 001; the pump air connector 034 is a gas connector, which serves to connect with the pump air assembly.

[0059] 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.

[0060] 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 inflated, 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 provision of the built-in air bags 004 and the existence of the auxiliary pontoons 003 and the main pontoons 002 greatly increase the impact resistance of the hull.

[0061] Furthermore, the built-in airbag 004 is an elastic rubber bag, which is a horizontally arranged columnar bag.

[0062] Preferably, there are multiple built-in air bags 004 in each auxiliary buoyancy tank 003.

[0063] Further, such as Figure 3As shown, the number of built-in air bags 004 in each auxiliary floating tank 003 is three, namely the front air bag 041, the middle air bag 042 and the rear air bag 043; the front air bag 041, the middle air bag 042 and the rear air bag 043 are respectively arranged near the front end, the middle part and the rear end of the hull, and the three are respectively communicated with the air pumping assembly through independent air pumping joints 034, and can be independently expanded and contracted to adjust the overall attitude of the hull, so as to change the center of gravity of the hull and balance the tilt of the hull caused by the distribution of the load.

[0064] As Figure 4 shown, further, a pressure increasing valve and a pressure releasing valve are arranged on the air delivery pipe of the air pumping assembly, and the pressure increasing valve and the pressure releasing valve are controlled by the control component to control the three states of the air delivery pipe being communicated with, disconnected from, and deflated from the built-in air bag 004; the pressure increasing valve and the pressure releasing valve form an interlock of one open and one closed, with one side open and the other side closed (three states: the pressure releasing valve is closed when the pressure increasing valve is open, the pressure increasing valve is closed when the pressure releasing valve is open, and both the pressure increasing valve and the pressure releasing valve are closed).

[0065] Preferably, the built-in air bag 004 is also communicated with a safety valve, and automatically exhausts air (releases excess gas) when the pressure in the bag is relatively high.

[0066] Preferably, the bottom of the auxiliary floating tank 003 is integrally open (that is, the auxiliary floating tank 003 has no bottom).

[0067] Preferably, one or more bottom holes 031 are arranged at the bottom of the auxiliary floating tank 003, and the bottom holes 031 are through holes.

[0068] Preferably, the bottom surfaces of the auxiliary floating tank 003, the main floating tank 002 and the basic hull 001 are coplanar.

[0069] Preferably, the two auxiliary floating tanks 003 are respectively positioned at the bottoms of the two main floating tanks 002.

[0070] Preferably, the number of the auxiliary floating tanks 003 is a multiple of 2, the auxiliary floating tanks 003 are positioned on one side and / or the bottom of the main floating tank 002, and the number of the auxiliary floating tanks 003 on the two main floating tanks 002 is equal and symmetrically arranged.

[0071] Further, due to the existence of the two closed boxes of the main floating tank 002, sufficient buoyancy is provided, and even if the basic hull 001 and the auxiliary floating tank 003 are integrally flooded, the hull will not sink.

[0072] When manufacturing the hull of the semi-submersible garbage salvage ship of the present application: it is necessary to install the main floating tank 002 on both sides of the basic hull 001, and install the built-in air bag 004 in the auxiliary floating tank 003; then fix the auxiliary floating tank 003 on the main floating tank 002; finally, connect the air pumping assembly with the built-in air bag 004.

[0073] The adjustment and control method of the hull of the semi-submersible garbage salvage ship in this application is as follows: when the ship is transferring in the empty state, the whole hull floats upward; when the ship arrives at the working area and needs to change from the fully floating state to the semi-submerged state (that is, reduce the gas volume in the auxiliary floating box 003 to make the whole hull sink); during the garbage collection process, as the collected objects (loads) increase, the draft depth increases; during the salvage operation, adjust the gas volume in the auxiliary floating box 003 so that the load capacity increases accordingly; when there is a loading imbalance, the inflation volume of one or more built-in air bags 004 can be changed to achieve the balance of the ship; when the loading volume reaches the rated value, the salvage operation stops.

[0074] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages:

[0075] It solves the technical problems in the prior art that the garbage salvage ship has a small load capacity, low operation efficiency, poor safety, poor navigation passability and stability, and a single function; it realizes the technical effects that the semi-submersible garbage salvage ship has a relatively large load capacity, relatively high operation efficiency, relatively good safety, less influence from the outside during navigation, strong passability, high stability, and diverse functions.

[0076] The load capacity of the hull has increased significantly: by changing the gas volume in the auxiliary floating box 003, the load capacity of the hull has increased significantly;

[0077] The operation efficiency has been improved: due to the load capacity limitation of ordinary ships, when the goods are loaded to a certain amount, the load limit of the hull is reached, and the goods must be transferred or the ship must return; the human and material resources spent are relatively large, resulting in an increase in costs; due to the increase in buoyancy of the hull in this application, the corresponding load capacity also increases, changing the original transport volume of two or three times into one transport volume; and in the actual application of the salvage ship (the salvage objects float on the water surface), as the cargo loading volume increases, the draft depth of the hull increases accordingly. Excessive water intake will affect the filtration efficiency and increase the energy consumption loss; too little water intake will cause slightly larger garbage to gather at the bow and not enter the cabin, requiring manual intervention; therefore, when the bow sinks due to the increase in load in the later stage of the salvage operation, the air bags on both sides of the bow can be controlled to lift the whole bow and reduce the draft depth of the bow; keep the draft depth of the stern unchanged, thereby increasing the filtration efficiency and indirectly improving the operation efficiency.

[0078] The safety has increased: the combination of the floating box and the flexible air bag provides better protection for the hull when the hull is impacted;

[0079] The passability of the hull has increased: it is a common phenomenon that the water levels of inland rivers and lakes are relatively shallow and the bridge bottoms on the river channels are low, and generally large ships are not suitable for navigation; in this application, the buoyancy of the hull needs to be adjusted. When passing a bridge, water enters the ship, the built-in air bag 004 is emptied, and the draft level of the ship becomes deeper;

[0080] Improved stability: When the goods are sometimes loaded unevenly, an ordinary ship will directly roll over, posing a safety hazard and affecting shipping safety. When the hull of this application is in use, the inflation volume of a single airbag can be increased to achieve the secondary balance of the ship, and the adjustment range is relatively large. In the actual use process, when the loading weight of the goods is uneven or the load on the bow is uneven, inflating the airbag on one side can lift one side of the ship and increase the stability of the ship.

[0081] Diverse functions and can be used for emergency disaster relief: When floods and other situations occur in the inland areas, ordinary ships cannot travel on the streets and farmlands and cannot be used as disaster relief ships. When the hull of this application needs to travel in shallow water areas, after closing the bow water baffle, all the water in the ship is drained, and all the built-in airbags 004 are opened. The draft of the ship reaches the lowest level, and the whole ship floats up, and it can be used in shallow water areas.

[0082] Embodiment 2

[0083] The semi-submersible garbage salvage ship hull in the embodiment of this application is different from the semi-submersible garbage salvage ship hull in Embodiment 1 in that: as Figure 5 shown, the setting of the built-in airbag 004 is cancelled, and the air pumping assembly is directly connected to the auxiliary floating box 003.

[0084] Since the setting of the built-in airbag 004 is cancelled, there is no need to set a safety valve on the air pumping assembly. When the gas is overfilled, it will leak out from the bottom of the ship, which is safer and has lower costs.

[0085] Preferably, one or more vertically arranged partition plates 032 are fixed in the auxiliary floating box 003; the partition plate 032 is a rigid plate body, which divides an auxiliary floating box 003 into multiple cavities with only openings at the bottom. Each cavity is independently connected to the air pumping assembly through a separate air pumping joint 034; when the hull attitude needs to be adjusted, it is achieved by adjusting the gas volume in the cavity.

[0086] Preferably, as Figure 6 shown, two vertically arranged partition plates 032 are fixed in the auxiliary floating box 003, and the two partition plates 032 divide the auxiliary floating box 003 into two side cavities and a middle cavity 033; the side cavities and the middle cavity 033 are all strip-shaped cavities.

[0087] Embodiment 3

[0088] The semi-submersible garbage salvage ship hull in the embodiment of this application is different from the semi-submersible garbage salvage ship hull in Embodiment 2 in that: an built-in airbag 004 is fixed in each cavity separated by the partition plate 032, and each built-in airbag 004 is independently connected to the air pumping assembly through an air pumping joint 034; the cavities separated by the partition plate 032 are not connected to the air pumping assembly (which can reduce the risk of water entering the air pumping assembly).

[0089] Further, the middle bladder 042 is located in the middle cavity 033, and the front bladder 041 and the rear bladder 043 are located in the side cavities.

[0090] Embodiment 4

[0091] To further improve the practicability and applicability of this application and increase functionality, in this embodiment of the application, on the basis of Embodiment 3, the structure of the middle bladder 042 in the middle cavity 033 is optimized and improved, so that the hull of this application still has good traveling ability when grounded, traveling on the mudflat, and moving in shallow water areas without the need for operators to get off the ship to push: specifically:

[0092] The bottom of the auxiliary floating box 003 is completely open;

[0093] As Figures 7 to 9 shown, the middle bladder 042 is formed by combining a plurality of plate-shaped bladder units 005 fixed together. The plurality of plate-shaped bladder units 005 are arranged in a row, are all vertically arranged and are integrally long strip-shaped. One end is fixed on the partition board 032 close to the front bladder 041, and the other end is fixed with a contact board 052; one end of the middle bladder 042 close to the front bladder 041 is communicated with the air pumping assembly through an air pumping joint 034;

[0094] The plate-shaped bladder unit 005 is a plate-shaped bladder body, which is formed by fixing the edges of two rubber sheets together. In the contracted state, it is a rectangular sheet or a circular sheet, and it bulges when inflated;

[0095] A plurality of plate-shaped bladder units 005 are stacked together and the central positions are fixed to the adjacent plate-shaped bladder units 005, and the adjacent plate-shaped bladder units 005 are communicated with each other; when the air pumping assembly inflates the middle bladder 042, the middle bladder 042 extends as a whole;

[0096] The contact board 052 is a rigid board body with a U-shaped longitudinal section, which is fixed at one end of the middle bladder 042 close to the rear bladder 043 and the opening faces the middle bladder 042, and is used to reduce the frictional damage suffered by the plate-shaped bladder units 005 during use;

[0097] A connecting rope 051 is fixed on the contact board 052; the connecting rope 051 is an elastic rubber rope, one end is fixed on the contact board 052, and the other end is fixed on the partition board 032 close to the rear bladder 043, and is always in a straightened state, and is used to limit the spatial positions of the middle bladder 042 and the contact board 052, and prevent the two from falling out of the bottom of the auxiliary floating box 003 due to their own weights;

[0098] 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.

[0099] When it is normally necessary 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, traveling on a mudflat, or moving in a shallow water area, 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.

[0100] 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.

[0101] Preferably, in order to reduce the wear of the top of the plate-like capsule unit 005 and the top wedge-shaped capsule 006, reduce the resistance encountered by the middle capsule 042 when extending, 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 transversely arranged strip-shaped metal sheet, and the top is close to the bottom of the top wedge-shaped capsule 006.

[0102] Preferably, each plate-shaped capsule unit 005 is filled with sponge and is normally in an expanded state.

[0103] Embodiment 5

[0104] In order to improve the flexibility of the hull movement, the hull of the present application can not only move forward but also move backward when the movement ability 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 contraction of the middle bag 042, and then control the expansion of the top wedge-shaped bag 006, and finally control the expansion and extension of the middle bag 042); when the hull needs to move backward, first control the extension of the middle bag 042, and then control the expansion of the top wedge-shaped bag 006, and push the ground cone 053 into the ground by squeezing, and finally control the contraction of the middle bag 042 to make the hull move backward.

[0105] Embodiment 6

[0106] In order to further improve the practicability and applicability of the hull of the present application, so that the hull still has the ability to temporarily travel in water when the power components fail; in the embodiment of the present application, an expansion accessory 007 is added on the basis of the above embodiment; the expansion accessory 007 functions as a paddle blade and is detachably installed on the contact plate 052; specifically:

[0107] As Figure 10 and Figure 11 shown, the expansion accessory 007 is integrally plate-shaped and includes a base plate 071, a rotating plate 072 and a limiting plate 073; the base plate 071 is vertically arranged and functions as a bearing connection;

[0108] The rotating plate 072 is a rigid straight plate, longitudinally arranged, and its top is 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;

[0109] The limiting plate 073 is a rigid plate body, which functions to limit the rotation angle of the rotating plate 072, is fixed to the bottom of the base plate 071 and is arranged close to the rotating plate 072; when the rotating plate 072 rotates to the vertical state, it contacts the rotating plate 072 to limit its further rotation;

[0110] After the expansion accessory 007 is installed, when the middle bladder 042 shortens, the rotating plate 072 rotates (the included angle with the base plate 071 decreases), and when the middle bladder 042 elongates, due to the resistance of water and the limiting effect of the limiting plate 073, the rotating plate 072 gradually rotates to the vertical state and pushes the water flow to drive the hull to move.

[0111] When the hull is in a state where the power components fail, the operator can detachably fix the base plate 071 on the contact plate 052 through buckles, bolts, etc., and use the expansion and contraction of the middle bladder 042 as the temporary power of the hull.

[0112] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. The built-in airbag 004 is integrally arranged on both sides of the hull. For a catamaran, it can also be placed at the bottom of the ship; however, in specific implementation, according to the size and use of the ship, increasing or decreasing the number, volume of the auxiliary floating tanks and / or airbags, and changing the position of the floating tanks are all within the scope; any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
