Description

Technical Field

[0001] The invention relates to a cruise ship, in particular to a cruise ship for water vacation. Background Art

[0002] The cruise ship described in the present invention is generally referred to as a cruise ship.

[0003] Cruise ships originally referred to large passenger ships that sailed regularly on fixed routes on the ocean. In the past, transoceanic mail was always carried by such large passenger ships, hence the name. After World War II, the civil aviation industry emerged and developed, and air transportation replaced the transportation function of cruise ships. The name cruise ship now actually refers to tourist passenger ships sailing on the ocean.

[0004] The service content and process currently provided by cruise ships mainly include: boarding the ship, checking into the guest room, sailing on the sea, experiencing the various dining and entertainment facilities on the cruise ship during the sea voyage, disembarking at the destination or going to scenic spots for leisure and sightseeing before boarding the ship again.

[0005] The main problem with cruise ships and travel modes in the prior art is that, although the cruise ships are sailing on the sea, they do not have relevant functions, so that passengers cannot experience water-friendly activities during the voyage, especially a large number of tourists can get close to natural water bodies at the same time. The results brought about by the above reasons are: first, passengers cannot get close to the sea water during the sea voyage, wasting passengers' vacation time; second, cruise ships in the prior art need to set up additional entertainment facilities and personnel to help passengers pass the sailing time to overcome the bad experience, but increase the unnecessary cost burden of passengers; third, in order to experience water-friendly activities in natural water bodies, passengers need to dock at the pier and disembark to experience water-friendly entertainment activities on the coast with sandy beaches, which puts certain requirements on the infrastructure of the destination, that is, scenic spots with insufficient facilities cannot become the destination of cruise travel, and more coasts and islands with good sightseeing and entertainment conditions are excluded; fourth, due to the reliance on infrastructure, the off-board water-friendly activities of cruise passengers are limited to limited beaches, and these places have suffered more damage to their original ecological environment due to excessive human activities.

[0006] In order to overcome the above defects, patent No. CN106275328B discloses a cruise ship lifting diving chamber, which can be used by multiple cruise passengers to enjoy underwater scenery. On a cruise ship named Celebrity Apex, a lifting platform installed on the side of the ship is used, which can carry dozens of cruise passengers from the cruise ship deck at a height of several dozen meters to a place close to the sea surface so that they can experience the sea water. There are also some small and medium-sized expedition cruise ships with partial hydrophilic decks at the stern like yachts. The common feature of these cruise ships is that the hydrophilic facilities are small in area and can only provide limited services. The satisfaction of a large number of passengers' hydrophilic activities still needs to rely on the infrastructure of the destination, such as hotels or attractions with beaches.

[0007] As for how to satisfy a large number of passengers to experience water-friendly activities at the same time without increasing the damage to the original ecology of the coast, the existing cruise ship technology and travel mode as well as other related existing technologies and methods do not provide an effective solution. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a method of use and a cruise ship body with corresponding functions, so that passengers can experience hydrophilic recreational activities in natural water bodies during the cruise, including but not limited to swimming, surfing, snorkeling, kayaking, sea fishing and net fishing, etc., especially a large number of passengers can experience hydrophilic activities at the same time.

[0009] The technical solution adopted by the present invention includes a method for using a cruise ship. That is:

[0010] S1. The cruise ship docks at the pier with a parking lot and resort hotel lobby at the agreed time. The deck height is adjusted to be at the same height as the pier. The daily necessities ordered by passengers online are delivered to the reserved living units on the cruise ship. Other materials for passengers' entertainment are loaded in place, such as kayaks, motorboats, speedboats, etc., which are loaded and fixed on the deck. The living units are cleaned, disinfected and replenished. The facilities on the cruise ship are checked item by item, and energy and drinking water are replenished, and other materials are prepared in place;

[0011] S2. Passengers arrive at the pier, board the ship through the resort hotel lobby and check into the reserved accommodation units before the cruise ship weighs anchor and leaves the port. During the cruise ship's departure, the deck height is adjusted to reduce the impact of surges on the cruise ship;

[0012] S3. After the cruise ship reaches the designated location, the deck height is adjusted so that the deck is partially or completely submerged in water, and passengers experience water sports or other recreational activities on the deck and the waters above the deck;

[0013] S4. The cruise ship approaches the destination island or coast and anchors, and passengers snorkel, swim, or take the boats and boats carried by the cruise ship to the island or coast for entertainment and sightseeing;

[0014] S5. When the cruise ship receives typhoon, earthquake and war warnings, passengers enter its underwater hull for refuge. When the destructive power of typhoons, earthquakes and wars encountered by the cruise ship reaches a certain value, the living unit modules of the superstructure are first separated from the core tube, and the cruise ship obtains strength redundancy after unloading the load. Its underwater hull can also replenish ballast water and go deeper underwater to avoid wind and waves on the water surface. When the destructive power of typhoons, earthquakes and wars encountered by the cruise ship increases to a certain value, the core tube and the underwater hull are separated, and the underwater hull carries the passengers to escape.

[0015] The technical solution adopted by the present invention also includes a cruise ship body: including an underwater hull, a core tube, a main frame, a deck and a superstructure. The underwater hull is a submarine, the underwater hull is connected to the core tube, the core tube is connected to the main frame, the main frame is connected to the deck, the core tube is also connected to the superstructure, the superstructure includes residential units and their supporting facilities, the supporting facilities include power supply, water supply, drainage, air supply, smoke exhaust, exhaust facilities serving the residential units, and buildings, elevators and corridors, antechambers and hallways outside the residential units for residential services and personnel use. The underwater hull controls its height in the water or on the water surface by adjusting the amount of ballast water in the hull, and controls the relative position of the cruise ship deck and the water surface by adjusting the buoyancy height of the underwater hull, so as to realize the free lifting and lowering change of the deck from below the sea surface to above the sea surface. The deck includes a main deck and a movable deck, at least a part of the deck is a hollow deck, and the movable deck can make displacement movement relative to the main deck, and the displacement movement can be rotational movement or translational movement. The core tube includes a tube wall and a hollow part of the tube body, and the hollow part can be installed with elevators, stairs, water supply pipes, drainage pipes, heating pipes, cables, air ducts, etc. The connection between the underwater hull and the core tube is a detachable structure, and the detachable structure is an integral structure or a mechanical connection. The separation of the integral structure is blasting separation or fracture separation when the material force exceeds a preset value. The blasting separation is manual separation or automatic separation, and the separation of the mechanical connection is also manual separation or automatic separation. The hull has a sealed hatch cover and can sail alone after being separated from the core tube. The underwater hull can be used as a lifeboat of the cruise ship.

[0016] Compared with the existing technology and method, the beneficial effects of the present invention are as follows: first, since the cruise ship itself is equipped with sufficient water-friendly activity facilities and space, passengers can experience water-friendly entertainment activities in natural water bodies during the voyage, and passengers do not need to wait on the ship and then rush to the destination to experience water-friendly entertainment activities, which saves passengers' vacation time; second, since the leisure and entertainment needs of passengers on board are fully satisfied, additional entertainment space, facilities and personnel are eliminated, and the hull replaces the lifeboat and the lifeboat storage and deployment facilities, thereby saving construction and operation costs, being more energy-saving and low-carbon, and reducing the cost of cruise vacations; third, the reduction of costs makes cruise travel accepted by more people, stimulates consumption, and expands the market for cruise travel; fourth, since cruise travel is no longer restricted by supporting facilities, cruise ships can go to more coasts and islands and reefs that have not been developed for tourism, so that tourists can experience more pristine natural water bodies and more pristine islands and reefs, and enhance the quality of cruise vacations; fifth, since cruise tourists are no longer concentrated in limited places, the ecological impact of cruise vacation tourism activities on the coast is reduced, so it is more environmentally friendly.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the implementation of the present invention clearer, the technical scheme in the embodiment of the present invention will be described in more detail below in conjunction with the accompanying drawings. In the accompanying drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The described embodiments are part of the embodiments of the present invention, not all of the embodiments. The embodiments described in the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] One end of the underwater hull 1 is a cockpit, and the other end is equipped with an underwater propulsion system 11. The underwater hull 1 is a submarine that provides all the buoyancy for the cruise ship to float on the water. The underwater hull 1 can adjust the size of the buoyancy by controlling the amount of ballast water inside it, thereby arbitrarily adjusting the relative position of the cruise ship deck and the water surface, for example: before outfitting, the underwater hull 1 is filled with ballast water of the same weight as its maximum load capacity, and as the superstructure 4 is installed, the ballast water of the same weight as the load added above is discharged accordingly, so that the deck 31 is at the same relative height or flush with the outfitting dock. When the cruise ship leaves the port, the ballast water volume is adjusted so that the lower edge of the main frame 3 is 2 to 5 meters above the water surface, forming sufficient wave-passing space under the main frame 3 to reduce the impact of surges on the cruise ship; when the water surface is calm, the ballast water volume is adjusted so that the lowest point of the main frame 3 is flush with the water surface, so that the deck 31 is as close to the water surface as possible, and passengers can better experience water-friendly entertainment activities on the deck 31; the ballast water volume is further adjusted so that the main frame 3 The deck 31 is sunk into the water, so that the deck 31 is kept at a position about 2 meters below the water surface, and the shark-proof net with buoys around the deck 31 is released at the same time. The water area above the deck 31 forms a safe natural swimming pool, and passengers experience water sports such as swimming, water polo, and snorkeling in the water area. When the cruise ship is moving forward at the same time, a water ski rope is set on the deck 31 every 10 meters in both longitudinal and transverse directions. One end of the water ski rope is connected to the deck 31 or the main frame 3, and the other end is a grabber floating on the water surface. Passengers can use the water ski rope to experience water skiing and surfing. Unlike speedboat water skiing and surfing, this embodiment can allow dozens of passengers to experience water skiing and surfing at the same time. The underwater hull 1 is also a lifeboat and shelter for the cruise ship. The connection 21 between the underwater hull 1 and the core tube 2 is an automatically detachable connection, which can withstand the force on the cruise ship during normal navigation. When the cruise ship encounters an earthquake, storm, tsunami or external explosion, when the force on the connection 21 reaches a certain value, the connection 21 is disconnected. For example, when the inclination of the core tube 2 is greater than 45 degrees, the huge torque when the core tube 2 is tilted causes the underwater hull 1 and the core tube 2 to separate at the connection 21, and the underwater hull 1 carries the passengers to escape. The airtightness and impact resistance of the outer wall and the entrance and exit of the underwater hull 1 meet certain anti-riot requirements, so that it can resist a certain level of explosion wave attack. When designed and constructed with corresponding indicators, the underwater hull 1 can be used as a refuge shelter of the corresponding level.

[0031] The core tube 2 is connected to the underwater hull 1 through the connection 21. The core tube 2 is connected above the underwater hull 1. There are more than one core tubes 2 on the underwater hull 1. The core tube 2 is connected to and supports the superstructure 4. The core tube 2 is hollow and has an outer wall support. The hollow part of the core tube 2 can be used for the installation and setting of the supporting facilities of the superstructure 4. All the supporting facilities of the superstructure 4, including corridors, can be installed inside the core tube 2, or only some supporting facilities, such as passenger elevators, can be installed. The supporting facilities of the superstructure 4 include but are not limited to corridors, antechambers, stairs, elevators, water supply and drainage wells, strong and weak current wells, wind wells, etc. The connection 21 between the core tube 2 and the underwater hull 1 is a fixed connection, which can withstand the pressure of the entire superstructure 4, and can also withstand a certain degree of tension and shear force, but cannot withstand torsion. When the connection 21 is subjected to torsion or the tension and shear force reach a certain value, the fixed connection of the connection 21 is automatically disconnected. In some embodiments, the connection 21 is a mechanical structure, and this connection can be automatically or manually disconnected under mechanical control. In other embodiments, the connection 21 is an integral structure, such as an integral fiber concrete structure. When the integral structure is a steel bar or steel plate concrete structure, the tensile steel of the connection 21 is a steel with low toughness and easy to break, and the amount of steel used is less than that of other parts. When the cruise ship is subjected to a large external force, the underwater hull 1 and the core tube 2 are disconnected at the connection 21, and the underwater hull 1 is no longer subjected to the destructive force transmitted by the core tube 2. At this time, the underwater hull 1, which has been unloaded from the conventional load, has sufficient redundant strength to resist the external force damage to itself under unconventional conditions.

[0032] The main frame 3 is a metal truss structure. The main frame 3 is connected to the core tube 2. The cruise ship is formed into a whole by fixing the core tube 2. A deck 31 is arranged on the upper part of the main frame 3. The main frame 3 is an open structure and can be immersed in water. In some embodiments, the main frame 3 has no skin. In other embodiments, the main frame 3 has a hollow skin, which is more beautiful and has less resistance when traveling. Part of the space inside the truss of the main frame 3 is also used to install part of the auxiliary equipment of the cruise ship or the superstructure 4.

[0033] The superstructure 4 is a unit-type residential building supported and connected by the core tube 2. In some embodiments, the superstructure 4 is a tower structure, and supporting facilities of the residential unit such as floors, elevators, corridors, water, heating, and electrical equipment rooms or wells are installed on the core tube 2, which may be partially around the core tube 2 and partially inside the core tube 2, or all inside the core tube 2 or all around the core tube 2; in other embodiments, the superstructure 4 connects no less than core tubes 2 together to form a plate-type superstructure 4 between the core tubes 2, and at this time, supporting facilities of the residential unit such as corridors, floors, elevators, water, heating, and electrical equipment rooms or wells are connected inside, around, and between two core tubes 2. The difference between a cruise ship and a conventional cruise ship is that the superstructure 4 includes a residential unit 41.

[0034] Living unit 41 is a minimum building unit that can accommodate two adults living comfortably for at least 7 days without leaving the house under normal water and electricity supply conditions, and includes a toilet room with dry and wet separation, a shower room, a bathtub, a wash area, a sleeping area, a dressing table, a refrigerator of no less than 300 liters, a storage wall cabinet, an island counter with cooking and dining functions, a leisure area with a sofa and a coffee table, a washing machine and a dryer, a clothes drying area, an entrance hall, etc.

[0035] The viewing platform 42 is connected to the core tube and is arranged above the roof of the superstructure 4.

[0036] The deck 31 is installed above the main frame. In the embodiment, part of the deck is a hollow metal mesh or a metal perforated plate, and part of it is a wooden or bamboo strip with gaps. In some embodiments, the deck can also be provided with holes with a size of more than 1 meter leading to the water surface, and elastic fabric nets are installed in the holes. The deck 31 can be used for passengers to carry out entertainment activities and sports on the water or in the water.

[0037] The movable deck 32 is arranged on the side of the deck 31. The movable deck 32 has an independent supporting structure. The connection between the movable deck 32 and the main frame 3 is hinged. The movable deck 32 can move independently relative to the deck 31. When the deck 31 is above the water surface, the movable deck 32 can be on the water surface, or it can be raised to a certain height above the water surface, or it can be partially underwater. The movable deck 32 can serve as a connection between the deck 31 and the dock and shoal, and can also serve as a supplement and extension of the activity space of the deck 31. For example, when the deck 31 sinks into the water, the movable deck 32 can be partially above the water surface for passengers to rest.

[0038] The buoy 33 is connected to the other side of the movable deck 32. The connection between the buoy 33 and the movable deck 32 is hinged. When a part or all of the movable deck 32 is above the water surface, the buoy 33 is on the side or below the movable deck 32; when the movable deck 32 is all or partly below the water surface, the buoy 33 is on the side or above the movable deck 32.

[0039] In some embodiments, when the superstructures 4 are towers, a bridge 43 is provided at the top layer between the superstructures 4 to connect the towers.

[0040] Attached Figure 1 , 2 The embodiment has two underwater hulls 1, each of which has two core tubes 2, and each core tube 2 has a set of superstructures 4. The four core tubes 2 of this embodiment are respectively connected to and fixed by the main frame 3, and the deck 31 laid on the main frame 3 is the main public activity space for the passengers of the cruise ship.

[0041] Attached Figure 5 , 6 is another embodiment, with the attached Figure 1 , 2 The difference between the embodiment is that the movable decks 32 and buoys 33 on both sides cannot leave the water surface, and the buoys 33 and movable decks 32 also have the function of supporting the cruise ship of the embodiment so that its core tube 2 remains vertical to the water surface.

[0042] The cruise ship of some embodiments has a construction method: the first step is to build the underwater hull 1 and the connection 21 between the core tube 2 and the underwater hull 1 in the dock, and after the above-mentioned parts are built, they are towed to the outfitting dock; the second step is to install and build a part of the core tube 2 from the connection 21 upward at the outfitting dock, and complete the installation of the main frame 3 and the laying of the deck 31; the third step is to build the core tube 2 above the deck 31; the fourth step is to assemble the component modules of the superstructure 4 layer by layer from bottom to top, and the superstructure 4 is prefabricated in the factory with building components or use units as modules; the fifth step is to outfit the power system and hydropower equipment and debug and operate them from local to overall.

[0043] In some embodiments, the cruise ship can also be used as a water residential building. In order to save construction cost and reduce use cost, when used as a water residential building, the underwater hull 1 and the core tube 2 can be built with reinforced concrete structure or steel plate concrete structure, and the building material of the superstructure 4 can be fiber concrete, composite material, metal or wood. The underwater propulsion system 11 can also be eliminated and replaced by towing by a tugboat, or a pod-type underwater propulsion system 11 can be installed on the main frame 3, and the underwater propulsion system 11 can be removed after it runs on its own and reaches the destination.

[0044] In some embodiments, a wind turbine and a communication antenna can be installed on the top of the cruise ship core tube 2. Since cruise ships can cruise on the sea in groups at regular intervals and on fixed routes, and cruise ships can be used as marine communication relay stations, a stable communication network can be formed when several cruise ships take turns operating on the route.

[0045] In some embodiments, ropes or nets are stretched between the core tubes 2 of the cruise ship, between the core tubes 2 and the outer edges of the deck 31 and the movable deck 32. The ropes or nets have automatically folded solar sails, which include multiple pairs of blades. The blades are thin solar cells, and the connection between the blades is a bimetallic strip or memory metal. The bimetallic strip or memory metal is in a folded state and unfolds only when the light or surface temperature reaches a certain value. For example, when the temperature exceeds 28 degrees Celsius, the blades open, can absorb solar energy, convert it into electrical energy, and transmit it to the battery of the cruise ship through the wires on the ropes, and can also block the sun for passengers on the deck 31.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate some technical solutions for implementing the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the present invention.
