Description

Technical Field

[0001] The present invention relates to the technical field of inflatable boats, and particularly to rigid inflatable boats. Background Art

[0002] In recent years, with the complex changes in the global maritime security situation, the frequency and diversity of naval escort missions have been increasing continuously, which puts forward higher requirements for the performance of shipborne boats. Early shipborne boats mainly used modified rescue boat hulls. Although this modified hull type can meet some mission requirements to a certain extent, there is an obvious gap in performance compared with specially designed shipborne boats. Against this background, traditional shipborne boats are no longer able to meet the growing mission requirements.

[0003] In some related technologies, rigid inflatable boats are used as shipborne boats. Rigid inflatable boats play an important role in tasks such as port patrol, boarding law enforcement, escorting and anti-piracy, due to their advantages such as light weight, high speed, and strong impact resistance.

[0004] A rigid inflatable boat usually consists of a hull, inflatable fenders, a propulsion system, a steering system, and a communication and navigation system. Among them, the inflatable fenders provide good anti-collision ability and resilience for the rigid inflatable boat on the one hand, and on the other hand, they also provide a large buoyancy for the rigid inflatable boat, making the hull light, improving the navigation performance in bad sea conditions, and reducing the waves hitting the deck. However, since the inflatable fenders need to withstand collisions, it is still inevitable that the inflatable fenders are damaged during use, resulting in the loss of buoyancy and the capsizing of the hull. The anti-sinking performance of rigid inflatable boats still needs to be further improved. Summary of the Invention

[0005] In view of this, the present invention provides a rigid inflatable boat to solve the problem of insufficient anti-sinking performance of existing rigid inflatable boats.

[0006] The present invention provides a rigid inflatable boat, including a hull and inflatable fenders. The hull includes a deck and a hull shell. The deck and the hull shell enclose a hull cabin. A plurality of bulkheads are arranged inside the hull cabin at intervals along the length direction of the hull to divide the hull cabin into a plurality of independent compartments. The compartments at least include a sealed forepeak cabin near the bow, and the forepeak cabin is used to fill gas to provide buoyancy. The inflatable fenders are arranged outside the hull.

[0007] Beneficial effects: The inflatable fender is filled with gas, thus providing basic buoyancy for the rigid inflatable boat. On this basis, the rigid inflatable boat further sets a bow peak cabin in the hull. On the one hand, the bow peak cabin can also provide buoyancy, and the hull is protected by the surrounding inflatable fenders. Therefore, the bow peak cabin is not easily damaged due to collision and can reliably provide buoyancy in the emergency situation where the surrounding inflatable fenders are damaged, improving the anti-sinking performance of the rigid inflatable boat; on the other hand, the bow peak cabin is close to the bow of the boat, which helps to increase the longitudinal inclination angle of the rigid inflatable boat and enables the rigid inflatable boat to obtain better navigation performance.

[0008] In an alternative embodiment, it further includes a power module. The power module includes a jet pump and a main engine. The cabin further includes a power cabin near the stern of the boat. The main engine is arranged in the power cabin, the jet pump is arranged at the stern of the boat, and the output end of the main engine is connected to the input end of the jet pump through an exhaust pipe.

[0009] Beneficial effects: The rigid inflatable boat uses a jet pump as the power source, making it suitable to set the center of gravity near the stern of the boat, which helps to further reduce the sliding resistance of the rigid inflatable boat and improve the sliding efficiency, so that the rigid inflatable boat obtains better navigation performance.

[0010] In an alternative embodiment, the power module further includes a steering gear. The steering gear is connected to the jet pump. The rigid inflatable boat further includes a control console, which is arranged on the deck. The control console is connected to the steering gear, and the control console is used to control the direction of the jet pump through the steering gear; the control console is arranged on one side of the hull close to the stern of the boat.

[0011] Beneficial effects: By controlling the direction change of the jet pump through the control console, the steering operation of the rigid inflatable boat is realized. By arranging the control console on one side of the hull close to the stern of the boat, it helps to set the center of gravity of the rigid inflatable boat further back, so that the rigid inflatable boat obtains better navigation performance.

[0012] In an alternative embodiment, the power module further includes a fuel tank. The cabin further includes a fuel tank located between the power cabin and the bow peak cabin. The fuel tank is arranged in the fuel tank, and the fuel tank is connected to the main engine through a fuel supply pipeline and a fuel return pipeline.

[0013] Beneficial effects: The fuel tank provides energy for the main engine. By placing the fuel tank in a separate fuel tank and separating the fuel tank from the power cabin, it can prevent the water entering the power cabin from flowing into the fuel tank and affecting the storage of fuel, improving the safety and reliability of the rigid inflatable boat.

[0014] In an alternative embodiment, the main engine includes a cooling pipeline, the water inlet and the water outlet of the cooling pipeline are located outside the engine room, and the water inlet and the water outlet are respectively used for sucking and discharging seawater.

[0015] Beneficial effects: During navigation, the main engine sucks seawater through the water inlet for heat exchange and cooling of itself, and then discharges it through the water outlet, thereby continuously cooling the main engine to ensure the operation and endurance of the rigid inflatable boat.

[0016] In an alternative embodiment, the cooling pipeline further includes a grille, a filter and a sea valve. The sea valve is used to control the opening degree of the cooling pipeline, and the grille and the filter are used to filter impurities in the seawater.

[0017] Beneficial effects: The sea valve can be used to adjust the heat exchange efficiency of the cooling pipeline to adapt to the working state of the main engine. By further providing a grille and a filter, foreign matters in the seawater can be prevented from blocking the cooling pipeline, which helps to ensure the normal operation of the cooling pipeline.

[0018] In an alternative embodiment, a safety module is further included. The safety module includes a water level sensor and an automatic pump. The water level sensor and the automatic pump are arranged in the engine room, and the water level sensor and the automatic pump are communicatively connected. The automatic pump is used to discharge the accumulated water in the engine room.

[0019] Beneficial effects: The automatic pump automatically discharges the excessive accumulated water in the engine room in response to the signal of the water level sensor, improving the anti-sinking performance of the rigid inflatable boat.

[0020] In an alternative embodiment, the inflatable fender includes partitions which are arranged at intervals along the length direction of the hull. The partitions divide the inflatable fender to form a plurality of independent watertight air chambers.

[0021] Beneficial effects: When some of the watertight air chambers are damaged due to collision, the other watertight air chambers can remain in a normal state and continue to provide buoyancy for the rigid inflatable boat, thereby improving the anti-sinking performance of the rigid inflatable boat.

[0022] In an alternative embodiment, a self-righting device is further included. The self-righting device is arranged on one side of the deck near the stern of the boat, and the self-righting device is used to automatically right itself when the rigid inflatable boat capsizes.

[0023] Beneficial effects: When the rigid inflatable boat accidentally capsizes, the self-righting device sinks into the water, generates a restoring moment through buoyancy, and makes the rigid inflatable boat automatically right itself, thereby improving the anti-sinking performance of the rigid inflatable boat and enhancing the survival ability of the rigid inflatable boat.

[0024] In an alternative embodiment, a communication and navigation module is further included, and the communication and navigation module includes at least one of a magnetic compass, a navigation system, a radiotelephone, and a radar transponder.

[0025] Advantageous effects: The communication and navigation module provides the rigid inflatable boat with the ability to communicate with the outside. The rigid inflatable boat can accurately determine the sailing direction through the magnetic compass and the navigation system, and establish communication links with other ships or the shore around through the radiotelephone and the radar transponder, ensuring the safety of navigation.

These terms may be used only to distinguish one element, component, region, layer or section from another.

[0035] Traditional shipborne boats mainly use modified rescue boat hulls. Although this type of modified hull can meet some mission requirements to a certain extent, there are obvious gaps in performance compared with specially designed shipborne boats. In recent years, with the complex changes in the global marine security situation, the frequency and diversity of naval escort missions have been increasing continuously, which puts higher requirements on the performance of shipborne boats. Against this background, traditional shipborne boats are already difficult to meet the growing mission requirements.

[0036] Rigid Inflatable Boats (RIBs) play an important role in tasks such as port patrol, boarding and law enforcement, escorting and anti-piracy due to their advantages of light weight, high speed, strong impact resistance, etc. Rigid Inflatable Boats are usually composed of a hull, inflatable fenders, a propulsion system, a steering system, and a communication and navigation system, and have excellent navigation performance and handling performance.

[0037] In related technologies, the inflatable fenders provide buoyancy for the Rigid Inflatable Boat, making the hull light, improving the navigation performance in bad sea conditions and reducing the deck from being washed by waves. However, since the inflatable fenders also bear the function of withstanding impacts, it is still inevitable that the inflatable fenders collide and get damaged during use, resulting in the loss of buoyancy and the capsizing of the hull. The anti-sinking performance of the Rigid Inflatable Boat still needs to be further improved.

[0038] The following will describe embodiments of the present invention in conjunction with Figures 1 to 2 .

[0039] Referring to Figure 1 and Figure 2 , according to an embodiment of the present invention, there is provided a Rigid Inflatable Boat, including a hull 1 and inflatable fenders 2. The hull 1 includes a deck 101 and a hull shell. The deck 101 and the hull shell enclose a hull cabin. A plurality of bulkheads 102 are arranged inside the hull cabin at intervals along the length direction of the hull 1 to divide the hull cabin into a plurality of independent cabins. The cabins at least include a sealed forepeak tank 103 near the bow. The forepeak tank 103 is used to fill gas to provide buoyancy. The inflatable fenders 2 are arranged outside the hull 1.

[0040] First, the inflatable fenders 2 are filled with gas, thus providing basic buoyancy for the Rigid Inflatable Boat.

[0041] On this basis, the Rigid Inflatable Boat further sets a forepeak tank 103 in the hull 1. On the one hand, the forepeak tank 103 can also provide buoyancy, and the hull 1 is protected by the surrounding inflatable fenders 2. Therefore, the forepeak tank 103 is not easily damaged due to collision and can reliably provide buoyancy in the emergency situation where the surrounding inflatable fenders 2 are damaged, improving the anti-sinking performance of the Rigid Inflatable Boat; on the other hand, the forepeak tank 103 is close to the bow, and the buoyancy generated by the forepeak tank 103 helps to increase the longitudinal inclination angle of the Rigid Inflatable Boat in the low-speed state, enabling the Rigid Inflatable Boat to obtain better navigation performance.

[0042] In some embodiments, the Rigid Inflatable Boat is a planing boat. In the low-speed state, the forepeak tank 103 provides buoyancy for the Rigid Inflatable Boat, making the Rigid Inflatable Boat have a better longitudinal inclination angle. In the high-speed state, the hull 1 is lifted, and the bottom of the hull 1 slides on the water surface, and the forepeak tank 103 is out of the water, thus not affecting the navigation performance of the Rigid Inflatable Boat in the high-speed state.

[0043] Exemplarily, referring toFigure 1 , in some embodiments, the hull 1 adopts a monohull planing hull form design. Alternatively, in some other embodiments not shown, the hull 1 adopts a catamaran planing hull form design. For the specific monohull planing hull form and catamaran planing hull form, reference can be made to the hull form design in the related art, which will not be elaborated here.

[0044] It should be noted that with reference to Figure 1 , the forepeak tank 103 needs to be at least partially located below the inflatable fender 2, so that the forepeak tank 103 is at least partially submerged below the water level in the low-speed navigation state, thereby producing the effect of providing buoyancy. Optionally, in some embodiments, the forepeak tank 103 is completely located below the inflatable fender 2. Specifically, since the inflatable fender 2 extends from the bow to the stern of the boat, "the forepeak tank 103 is located below the inflatable fender 2" means that based on the attitude of the rigid inflatable boat in a stationary and unladen state, the highest point of any longitudinal position on the forepeak tank 103 is below the lowest point of the inflatable fender 2 at the same longitudinal position.

[0045] Particularly, in some embodiments, the rigid inflatable boat adopts water jet propulsion. Specifically, the rigid inflatable boat further includes a power module, and the power module includes a jet pump 301 and a main engine 302. The jet pump 301 is arranged at the stern of the boat, and the output end of the main engine 302 is connected to the input end of the jet pump 301 through an exhaust pipe. It can be understood that the propulsion methods of rigid inflatable boats generally include water jet propulsion and propeller propulsion. Compared with propeller propulsion, the position of the main engine 302 in water jet propulsion can be relatively more rearward (close to the stern of the boat), so that the center of gravity of the rigid inflatable boat is at a position close to the stern, which helps to further reduce the planing resistance of the rigid inflatable boat and improve the planing efficiency, thereby enabling the rigid inflatable boat to obtain better navigation performance.

[0046] In some embodiments, the hull 1 adopts a polyethylene fiberglass reinforced composite material, so as to reduce the weight of the hull 1 while ensuring the strength and impact resistance of the hull 1, which helps the rigid inflatable boat to plane on the water surface at high speed.

[0047] Optionally, the cabin further includes a power cabin 105 near the stern of the boat, and the main engine 302 is arranged in the power cabin 105, so that the main engine 302 is close to the stern of the boat. By providing an independent power cabin 105 for placing the main engine 302, it is convenient for the daily maintenance and management of the main engine 302. In addition, in some embodiments, the main engine 302 is also connected with an exhaust pipe extending to the stern of the boat, so as to facilitate the external discharge of gas when the main engine 302 is running.

[0048] It can be understood that the power module further includes a steering gear 304. The steering gear 304 is connected to the jet pump 301. The rigid inflatable boat further includes a control console 401. The control console 401 is arranged on the deck 101. The control console 401 is connected to the steering gear 304. The control console 401 is used to control the direction of the jet pump 301 through the steering gear 304. By controlling the direction change of the jet pump 301 through the control console 401, the steering operation of the rigid inflatable boat is realized.

[0049] In some embodiments, the control console 401 is arranged on one side of the hull 1 close to the stern. By arranging the control console 401 on one side of the hull 1 close to the stern, it helps to further set the center of gravity of the rigid inflatable boat further backward, so that the rigid inflatable boat obtains better sailing performance.

[0050] In some embodiments, a storage battery 402 is further arranged in the control console 401. The storage battery 402 provides power for the functions of the control console 401 (such as control and instrument display, etc.).

[0051] In some embodiments, the power module further includes a fuel tank 303. The cabin further includes a fuel tank 104 located between the power cabin 105 and the bow peak cabin 103. The fuel tank 303 is arranged in the fuel tank 104. The fuel tank 303 is connected to the main engine 302 through an oil supply pipeline and an oil return pipeline.

[0052] The fuel tank 303 provides energy for the main engine 302. By placing the fuel tank 303 in a separate fuel tank 104, the fuel tank 104 is separated from the power cabin 105, which can prevent the water in the power cabin 105 from flowing into the fuel tank 104 and affecting the storage of fuel, and improve the safety and reliability of the rigid inflatable boat.

[0053] It can be understood that in order to improve the watertightness between the power cabin 105 and the fuel tank 104, the positions where pipelines such as the oil supply pipeline and the oil return pipeline pass through the bulkhead 102 are sealed with a sealing material for the gap between the pipeline and the bulkhead 102. The sealing material can be a sealing ring, a sealant and other sealing materials commonly used in related technologies, which will not be elaborated here.

[0054] In some embodiments, the main engine 302 includes a cooling pipeline. The water inlet and outlet of the cooling pipeline are located outside the power cabin 105. The water inlet and outlet are respectively used for sucking and discharging seawater. During navigation, the main engine 302 sucks seawater through the water inlet, exchanges heat and cools itself, and then discharges it through the water outlet, so as to continuously cool the main engine 302 and ensure the operation and endurance of the rigid inflatable boat.

[0055] In some embodiments, the cooling pipeline further includes a grille, a filter, and a sea valve. The sea valve is used to control the opening degree of the cooling pipeline, and the grille and the filter are used to filter impurities in seawater. The sea valve can be used to adjust the heat exchange efficiency of the cooling pipeline to adapt to the working state of the main engine 302. By further providing the grille and the filter, foreign objects in seawater can be prevented from blocking the cooling pipeline, which helps to ensure the normal operation of the cooling pipeline.

[0056] Specifically, the cooling pipeline can be provided with two water inlets, which are respectively arranged on both sides of the hull to suck seawater from both sides. Correspondingly, the cooling pipeline is provided with two sets of grilles, filters, and sea valves to respectively correspond to the two water inlets, realizing independent control and filtration of the water inlets.

[0057] In some embodiments, the rigid inflatable boat further includes a safety module. The safety module includes a water level sensor and an automatic pump 501. The water level sensor and the automatic pump 501 are arranged in the power cabin 105, and the water level sensor and the automatic pump 501 are communicatively connected. The automatic pump 501 is used to drain the accumulated water in the power cabin 105. The automatic pump 501 can automatically drain the excessive accumulated water in the power cabin 105 in response to the signal of the water level sensor, improving the anti-sinking performance of the rigid inflatable boat.

[0058] Optionally, in some embodiments, the safety module may further include a hand pump 502 and an emergency repair kit. When the automatic pump 501 fails, the accumulated water in the power cabin 105 can be manually drained through the hand pump 502. When the power cabin 105 or other positions of the hull 1 are damaged and water enters, the emergency repair kit can be used to perform emergency repairs on the water inlet point, improving the anti-sinking performance of the rigid inflatable boat.

[0059] In some embodiments, the inflatable fender 2 includes partitions, which are arranged at intervals along the length direction of the hull 1. The partitions divide the inflatable fender 2 to form a plurality of independent watertight air chambers. When a part of the watertight air chambers are damaged due to collision, the other watertight air chambers can remain in a normal state and continue to provide buoyancy for the rigid inflatable boat, thereby improving the anti-sinking performance of the rigid inflatable boat.

[0060] In some embodiments, mooring rings 701 are provided on the inflatable fender 2. The mooring rings 701 are used to be fastened to a transportation tool during transportation. Specifically, referring to Figure 1 , a plurality of mooring rings 701 can be arranged at intervals along the length direction of the hull 1 on the inflatable fender 2. The mooring rings 701 are made of a metal material (such as stainless steel). When idle, a rope passes through the plurality of mooring rings 701 and is connected to a mooring point of a transportation tool (such as a ship), thereby firmly fastening the rigid inflatable boat and preventing the rigid inflatable boat from moving during transportation.

[0061] In some embodiments, the rigid inflatable boat further includes a mooring bitt 703 which is arranged on the deck 101 at the bow of the boat. The mooring bitt 703 is used for mooring a cable, so as to facilitate the rigid inflatable boat to dock at a port or a wharf.

[0062] In some embodiments, the rigid inflatable boat further includes a suspension mechanism 702 which is used for connecting a lifting hook, so as to facilitate the handling and releasing of the rigid inflatable boat. Optionally, the suspension mechanism 702 is located in the middle section of the deck 101, and the control console 401 is located behind the suspension mechanism 702.

[0063] In some embodiments, the rigid inflatable boat further includes a self-righting device which is arranged on one side of the deck 101 near the stern of the boat. The self-righting device is used for self-righting when the rigid inflatable boat capsizes. When the rigid inflatable boat accidentally capsizes, the self-righting device sinks into the water, generates a restoring moment through buoyancy, and changes parameters such as the draft, floating state and position of the center of buoyancy of the rigid inflatable boat, so that the rigid inflatable boat self-rights itself, thereby improving the anti-sinking performance of the rigid inflatable boat and enhancing the survival ability of the rigid inflatable boat.

[0064] Specifically, the self-righting device includes a bracket 601 and a floating body 602. The bracket 601 is arranged on one side of the deck 101 near the stern of the boat, and the floating body 602 is arranged on the bracket 601. The bracket 601 makes the floating body 602 higher than the deck 101, so as to fully sink into the water when capsizing, and the floating body 602 is used for generating buoyancy.

[0065] Optionally, in some embodiments, the floating body 602 adopts an inflatable floating body. During normal navigation, the floating body 602 is in a contracted state without inflation, which helps to reduce the wind resistance of the floating body 602 and is beneficial to the high-speed sliding of the rigid inflatable boat. When the rigid inflatable boat accidentally capsizes, the floating body 602 inflates and expands under manual or automatic control, so that the rigid inflatable boat self-rights itself.

[0066] Alternatively, in some other embodiments, the floating body 602 can also adopt a solid floating body. At this time, the floating body 602 is mainly composed of light materials such as EVA (ethylene-vinyl acetate copolymer) and pearl cotton with a density much smaller than that of water.

[0067] In some embodiments, the rigid inflatable boat further includes a communication and navigation module, and the communication and navigation module includes at least one of a magnetic compass, a navigation system, a radiotelephone, and a radar transponder.

[0068] The communication and navigation module provides the rigid inflatable boat with the ability to communicate with the outside world. Among them, the magnetic compass realizes the heading indication through the physical characteristics of the earth's magnetic field and the magnetic needle. The navigation system can include functions such as satellite navigation systems (GPS, Beidou, etc.), inertial navigation systems, and electronic nautical charts. The rigid inflatable boat can accurately determine the navigation direction through the magnetic compass and the navigation system. The radar transponder automatically activates and transmits encoded response signals by receiving the detection pulse signals sent by external radars. The rigid inflatable boat can establish communication links and signal recognition with other ships or the shore around through the radiotelephone and the radar transponder, ensuring navigation safety.

[0069] Optionally, in some embodiments, the communication and navigation module is integrated in the control console 401 for the driver to use when driving the rigid inflatable boat. Specifically, the graphical user interface and the control panel of the communication and navigation module can be integrated on the instrument panel of the control console 401. At this time, the storage battery 402 can also be responsible for providing power for the communication and navigation module.

[0070] The rigid inflatable boat provided by the present invention has excellent seaworthiness, can maintain high stability during fast navigation, has strong resistance to wind and waves, can operate stably in complex sea conditions, and at the same time shows good flexibility. The rigid inflatable boat can be configured on large and medium-sized military and police surface ships and is applicable to multiple mission scenarios such as material transfer, rapid personnel transportation, and maritime patrol, with a wide range of applications.

[0071] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
