Description

Technical Field

[0001] This utility model relates to the field of inflatable boat technology, specifically to rigid inflatable boats. Background Technology

[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, placing higher demands on the performance of shipborne vessels. Early shipborne vessels were mainly converted rescue boats. While these conversions could meet some mission requirements to a certain extent, their performance lagged significantly behind that of specially designed shipborne vessels. Against this backdrop, traditional shipborne vessels are no longer sufficient to meet the growing mission demands.

[0003] Some related technologies use rigid inflatable boats as shipboard vessels. Rigid inflatable boats play an important role in port patrols, boarding law enforcement, escorting ships, and anti-piracy missions due to their advantages such as being lightweight, high-speed, and highly impact-resistant.

[0004] Rigid inflatable boats typically consist of a hull, inflatable fenders, a propulsion system, a steering system, and a communication and navigation system. The inflatable fenders provide excellent collision protection and resilience, as well as significant buoyancy, making the hull lightweight, improving navigation performance in rough seas, and reducing deck splashes. However, because inflatable fenders are subject to collisions, damage can still occur during use, leading to loss of buoyancy and capsizing. Therefore, the anti-sinking properties of rigid inflatable boats still need further improvement. Utility Model Content

[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] This utility model provides a rigid inflatable boat, including a hull and an inflatable fender. The hull includes a deck and a hull shell, which enclose a cabin. The cabin is provided with multiple bulkheads, which are spaced apart along the length of the hull to divide the cabin into multiple independent compartments. Each compartment includes at least a sealed bow tip compartment near the bow, which is filled with gas to provide buoyancy. The inflatable fender is located on the outside of the hull.

[0007] Beneficial effects: The inflatable fenders are filled with gas, providing basic buoyancy for the rigid inflatable boat. Furthermore, the rigid inflatable boat incorporates a bow capsule within the hull. On one hand, the bow capsule also provides buoyancy, and because the hull is protected by the surrounding inflatable fenders, it is less prone to damage from collisions. This allows it to reliably provide buoyancy in emergency situations where the surrounding inflatable fenders are damaged, improving the rigid inflatable boat's anti-sinking capability. On the other hand, the bow capsule's proximity to the bow helps increase the rigid inflatable boat's heel angle, resulting in better sailing performance.

[0008] In one alternative embodiment, a power module is also included, which includes a jet pump and a main engine. The compartment also includes a power room near the stern, where the main engine is located. The jet pump is located at the stern, and the output of the main engine is connected to the input of the jet pump via an exhaust pipe.

[0009] Beneficial effects: Rigid inflatable boats use jet pumps as their power source, which allows them to place their center of gravity near the stern. This helps to further reduce the skidding resistance of the rigid inflatable boat, improve skidding efficiency, and thus enable the rigid inflatable boat to achieve better sailing performance.

[0010] In one alternative embodiment, the power module further includes a servo motor connected to the jet pump, and the rigid inflatable boat further includes a control console disposed on the deck and connected to the servo motor. The control console is used to control the direction of the jet pump via the servo motor. The control console is disposed on the side of the hull near the stern.

[0011] Beneficial effects: The rigid inflatable boat can be steered by controlling the direction of the jet pump through the control console. By placing the control console on the side of the hull closer to the stern, the center of gravity of the rigid inflatable boat can be further shifted aft, thus giving the rigid inflatable boat better sailing performance.

[0012] In one alternative embodiment, the power module further includes a fuel tank, and the compartment further includes a fuel tank located between the power compartment and the forepeak compartment. The fuel tank is disposed in the fuel tank and is connected to the main engine via fuel supply lines and fuel return lines.

[0013] Beneficial effects: The fuel tank provides power to the main engine. By placing the fuel tank in a separate fuel compartment, which is separated from the engine compartment, it is possible to prevent water from entering the engine compartment and flowing into the fuel compartment, thus affecting the storage of fuel and improving the safety and reliability of the rigid inflatable boat.

[0014] In one alternative embodiment, the main unit includes a cooling pipeline with an inlet and an outlet located outside the power compartment, the inlet and outlet being used to draw in and discharge seawater, respectively.

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

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

[0017] Beneficial effects: The heat exchange efficiency of the cooling pipes can be adjusted by using the seabed valve to adapt to the working status of the main unit. By further setting up the grille and filter, foreign objects in the seawater can be prevented from clogging the cooling pipes, which helps to ensure the normal operation of the cooling pipes.

[0018] In one alternative embodiment, a safety module is also included, comprising a water level sensor and an automatic pump, the water level sensor and the automatic pump being disposed within the power compartment and communicatively connected, the automatic pump being used to drain accumulated water from the power compartment.

[0019] Beneficial effects: The automatic pump responds to the signal from the water level sensor to automatically drain excess water from the engine compartment, improving the buoyancy of the rigid inflatable boat.

[0020] In one alternative embodiment, the inflatable fender includes bulkheads spaced apart along the length of the hull, which divide the inflatable fender into multiple independent watertight air chambers.

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

[0022] In one alternative embodiment, a self-righting device is also included, which is disposed on the side of the deck near the stern and is used to right the rigid inflatable boat itself in the event of capsizing.

[0023] Beneficial effects: When a rigid inflatable boat capsizes unexpectedly, the self-righting device is submerged in the water and generates a restoring torque through buoyancy, causing the rigid inflatable boat to right itself, thereby improving the rigid inflatable boat's resistance to sinking and enhancing its survivability.

[0024] In one alternative implementation, the system further includes a communication and navigation module, which includes at least one of a magnetic compass, a navigation system, a wireless telephone, and a radar transponder.

[0025] Beneficial effects: The communication and navigation module provides rigid inflatable boats with communication capabilities with the outside world. Rigid inflatable boats can accurately determine their navigation direction through magnetic compasses and navigation systems, and establish communication links with other ships or shore in the vicinity through radio telephones and radar transponders, ensuring navigation safety.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0033] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this application, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection via an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0035] Traditional shipborne vessels are mainly converted from rescue boats. While these conversions can meet some mission requirements, their performance is significantly inferior to that of specially designed shipborne vessels. In recent years, with the increasingly complex global maritime security situation, the frequency and diversity of naval escort missions have been continuously increasing, placing higher demands on the performance of shipborne vessels. Against this backdrop, traditional shipborne vessels are no longer sufficient to meet the growing mission requirements.

[0036] Rigid inflatable boats (RIBs) play a vital role in port patrols, law enforcement boarding, and anti-piracy escort missions due to their lightweight, high speed, and strong impact resistance. A typical RIB consists of a hull, inflatable fenders, a propulsion system, a steering system, and a communication and navigation system, offering excellent sailing and maneuverability.

[0037] In related technologies, inflatable fenders provide buoyancy to rigid inflatable boats, making the hull lighter, improving navigation performance in rough seas, and reducing deck surfacing. However, since inflatable fenders also bear the impact load, collisions can still cause damage, leading to loss of buoyancy and capsizing. Therefore, the anti-sinking properties of rigid inflatable boats still need further improvement.

[0038] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0039] Reference Figure 1 , Figure 2 According to an embodiment of the present invention, a rigid inflatable boat is provided, including a hull 1 and an inflatable fender 2. The hull 1 includes a deck 101 and a hull shell, which enclose a cabin. The cabin is provided with multiple bulkheads 102, which are spaced apart along the length of the hull 1 to divide the cabin into multiple independent compartments. Each compartment includes at least a sealed bow tip compartment 103 near the bow, which is filled with gas to provide buoyancy. The inflatable fender 2 is provided on the outside of the hull 1.

[0040] First, the inflatable fender 2 is filled with gas, thus providing basic buoyancy for the rigid inflatable boat.

[0041] Based on this, the rigid inflatable boat further incorporates a bow tip compartment 103 within the hull 1. On one hand, the bow tip compartment 103 can also provide buoyancy, and since the hull 1 is protected by the surrounding inflatable fenders 2, the bow tip compartment 103 is not easily damaged by collisions and can reliably provide buoyancy in emergency situations where the surrounding inflatable fenders 2 are damaged, thus improving the rigid inflatable boat's anti-sinking capability. On the other hand, the bow tip compartment 103 is close to the bow, and the buoyancy generated by the bow tip compartment 103 helps to increase the pitch angle of the rigid inflatable boat at low speeds, enabling the rigid inflatable boat to obtain better sailing performance.

[0042] In some embodiments, the rigid inflatable boat is a planing boat. At low speeds, the bow tip 103 provides buoyancy to the rigid inflatable boat, giving it a better pitch angle. At high speeds, the hull 1 is lifted, the bottom of the hull 1 skims along the water, and the bow tip 103 leaves the water, thus not affecting the rigid inflatable boat's navigation performance at high speeds.

[0043] For example, refer to Figure 1 In some embodiments, the hull 1 adopts a monohull planing hull design, or in other embodiments not shown, the hull 1 adopts a catamaran planing hull design. The specific monohull planing hull and catamaran planing hull designs can be referred to the hull design in related technologies, and will not be described in detail here.

[0044] It should be noted that, referring to Figure 1 The bow tip 103 needs to be at least partially located below the inflatable fender 2 so that it is at least partially submerged below the horizontal plane during low-speed navigation, thereby providing buoyancy. Optionally, in some embodiments, the bow tip 103 is completely located below the inflatable fender 2. Specifically, since the inflatable fender 2 extends from the bow to the stern, "the bow tip 103 is located below the inflatable fender 2" means that, based on the attitude of the rigid inflatable boat in a stationary, unloaded state, the highest point of any longitudinal position on the bow tip 103 is located below the lowest point of the inflatable fender 2 at the same longitudinal position.

[0045] Specifically, in some embodiments, the rigid inflatable boat employs water jet propulsion. Specifically, the rigid inflatable boat also includes a power module comprising a jet pump 301 and a main engine 302. The jet pump 301 is located at the stern, and the output of the main engine 302 is connected to the input of the jet pump 301 via an exhaust pipe. It is understood that rigid inflatable boats generally employ either water jet propulsion or propeller propulsion. Compared to propeller propulsion, in water jet propulsion, the main engine 302 can be positioned further aft (closer to the stern), placing the rigid inflatable boat's center of gravity closer to the stern. This helps to further reduce the boat's sliding resistance, improve sliding efficiency, and thus achieve better sailing performance.

[0046] In some embodiments, the hull 1 is made of polyethylene glass fiber reinforced composite material, thereby reducing the weight of the hull 1 while ensuring its strength and impact resistance, which helps the rigid inflatable boat to glide close to the water at high speeds.

[0047] Optionally, the compartment also includes a power room 105 near the stern, with the main engine 302 housed within the power room 105, thus bringing the main engine 302 close to the stern. Providing a separate power room 105 for the main engine 302 facilitates its routine maintenance and management. Additionally, in some embodiments, the main engine 302 is connected to an exhaust pipe extending to the stern, facilitating the exhaust of gases during operation.

[0048] Understandably, the power module also includes a servo motor 304, which is connected to the jet pump 301. The rigid inflatable boat also includes a control console 401, which is mounted on the deck 101 and connected to the servo motor 304. The control console 401 is used to control the direction of the jet pump 301 via the servo motor 304. By controlling the direction of the jet pump 301 through the control console 401, the rigid inflatable boat can be steered.

[0049] In some embodiments, the control console 401 is located on the side of the hull 1 near the stern. By placing the control console 401 on the side of the hull 1 near the stern, it helps to further shift the center of gravity of the rigid inflatable boat aft, thereby enabling the rigid inflatable boat to achieve better sailing performance.

[0050] In some embodiments, a battery 402 is also provided in the control panel 401, which provides power for the functions of the control panel 401 (such as operation and instrument display).

[0051] In some embodiments, the power module further includes a fuel tank 303, and the compartment further includes a fuel tank 104 located between the power compartment 105 and the forepeak compartment 103. The fuel tank 303 is disposed in the fuel tank 104 and is connected to the main engine 302 through a fuel supply line and a fuel return line.

[0052] Fuel tank 303 provides energy to main engine 302. By placing fuel tank 303 in a separate fuel tank 104, which is separated from power compartment 105, water entering power compartment 105 can be prevented from flowing into fuel tank 104 and affecting fuel storage, thus improving the safety and reliability of rigid inflatable boat.

[0053] Understandably, to improve the watertightness between the engine compartment 105 and the fuel tank 104, the gaps between the fuel supply lines, return lines, and other pipelines that pass through the bulkhead 102 are sealed with sealing material. The sealing material can be commonly used in related technologies such as sealing rings and sealants, which will not be elaborated upon here.

[0054] In some embodiments, the main engine 302 includes cooling pipes with inlets and outlets located outside the power compartment 105. The inlets and outlets are used to draw in and discharge seawater, respectively. During navigation, the main engine 302 draws in seawater through the inlet to exchange heat and cool itself, and then discharges it through the outlet, thereby continuously cooling the main engine 302 and ensuring the operation and endurance of the rigid inflatable boat.

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

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

[0057] In some embodiments, the rigid inflatable boat also includes a safety module comprising a water level sensor and an automatic pump 501. The water level sensor and the automatic pump 501 are disposed within the power compartment 105 and are communicatively connected. The automatic pump 501 is used to drain water accumulated in the power compartment 105. The automatic pump 501 can automatically drain excess water from the power compartment 105 in response to a signal from the water level sensor, thereby improving the rigid inflatable boat's resistance to sinking.

[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 malfunctions, the water in the engine compartment 105 can be manually drained by the hand pump 502. When water enters the engine compartment 105 or other parts of the hull 1 due to damage, the emergency repair kit can be used to repair the water ingress point, thereby improving the anti-sinking capability of the rigid inflatable boat.

[0059] In some embodiments, the inflatable fender 2 includes bulkheads spaced apart along the length of the hull 1, dividing the inflatable fender 2 into multiple independent watertight air chambers. When some of the watertight air chambers are damaged in a collision, the others remain intact, continuing to provide buoyancy to the rigid inflatable boat, thereby improving the boat's resistance to sinking.

[0060] In some embodiments, the inflatable fender 2 is provided with a mooring ring 701, which is used to secure the fender to the vehicle during transportation. Specifically, refer to... Figure 1 Multiple mooring rings 701 can be spaced along the length of the hull 1 on the inflatable fender 2. The mooring rings 701 are made of metal (e.g., stainless steel). When not in use, ropes pass through the multiple mooring rings 701 and are connected to the mooring point of the transport vehicle (e.g., a ship) to securely fasten the rigid inflatable boat and prevent it from moving during transport.

[0061] In some embodiments, the rigid inflatable boat also includes a mooring bollard 703, which is disposed on the deck 101 at the bow of the boat and is used to secure the mooring line so that the rigid inflatable boat can be moored in a port or dock.

[0062] In some embodiments, the rigid inflatable boat further includes a suspension mechanism 702 for connecting a hook to facilitate the handling and release 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 also includes a self-righting device disposed on the side of the deck 101 near the stern. The self-righting device is used to right the rigid inflatable boat itself in the event of capsizing. When the rigid inflatable boat capsizes accidentally, the self-righting device submerges in the water and generates a restoring torque through buoyancy, changing parameters such as the draft, buoyancy state, and center of buoyancy of the rigid inflatable boat, thereby enabling the rigid inflatable boat to right itself, thus improving the rigid inflatable boat's resistance to sinking and enhancing its survivability.

[0064] Specifically, the self-righting device includes a support 601 and a float 602. The support 601 is located on the side of the deck 101 near the stern, and the float 602 is located on the support 601. The support 601 makes the float 602 higher than the deck 101, so that it is fully submerged in the water when capsizing, and the float 602 is used to generate buoyancy.

[0065] Optionally, in some embodiments, the float 602 is an inflatable float. During normal navigation, the float 602 is in a deflated, uninflated state, which helps reduce wind resistance and facilitates high-speed gliding of the rigid inflatable boat. When the rigid inflatable boat accidentally capsizes, the float 602 inflates under manual or automatic control, causing the rigid inflatable boat to right itself.

[0066] Alternatively, in some other embodiments, the float 602 may also be a solid float, in which case the float 602 is mainly composed of lightweight materials such as EVA (ethylene-vinyl acetate copolymer) and pearl cotton, which have a density much lower than that of water.

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

[0068] The communication and navigation module provides the rigid inflatable boat with external communication capabilities. The magnetic compass uses the Earth's magnetic field and the physical properties of a magnetic needle to indicate course. The navigation system can include satellite navigation systems (GPS, BeiDou, etc.), inertial navigation systems, electronic charts, and other functions. The rigid inflatable boat can accurately determine its bearing using the magnetic compass and navigation system. The radar transponder automatically activates and transmits a coded response signal upon receiving detection pulse signals from external radar. The rigid inflatable boat can establish communication and signal identification with other ships or shore-based facilities via radio and radar transponder, ensuring navigational safety.

[0069] Optionally, in some embodiments, the communication and navigation module is integrated into the control panel 401 for use by the driver when operating the rigid inflatable boat. Specifically, the graphical user interface and control panel of the communication and navigation module can be integrated into the instrument panel of the control panel 401. In this case, the battery 402 can also be responsible for providing power to the communication and navigation module.

[0070] The rigid inflatable boat provided by this utility model possesses excellent seaworthiness, maintains high stability during high-speed navigation, has strong resistance to wind and waves, can operate stably in complex sea conditions, and also exhibits good flexibility. The rigid inflatable boat can be deployed on medium and large-sized military and police surface vessels and is suitable for various mission scenarios such as material transfer, rapid personnel transport, and maritime patrol, making it widely applicable.

[0071] Although 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.
