Description

Technical Field

[0001] This invention relates to the field of inflatable boat technology, specifically to a self-righting and anti-sinking inflatable boat. Background Technology

[0002] The self-righting and anti-sinking inflatable boat is a watercraft that integrates safety, reliability, and efficiency. It combines core technologies such as pure mechanical self-righting, multiple anti-sinking mechanisms, and stability adjustment, breaking through the pain points of traditional inflatable boats, such as difficulty in repositioning after capsizing and easy sinking after damage. It is widely applicable to various scenarios such as emergency rescue, maritime patrol, water operations, recreational navigation, and complex and harsh waters, meeting both professional operation needs and ensuring safety for daily water travel.

[0003] Patent publication number CN221660921U includes a hull, with a control console installed inside the hull's cabin; a righting mechanism is installed on the upper part of the hull's outer wall. This is a self-righting vessel. When the attitude sensor detects that the hull is tilting, the controller controls the air tank to open and inflate the airbag on the tilted side. The airbag generates buoyancy in the water, propelling the hull. At the same time, the controller controls the electric hydraulic rod on the same side as the inflated airbag to start, thereby causing the electric hydraulic rod to push the counterweight block to move in the opposite direction, correcting the hull's center of gravity, and realizing automatic righting of the hull, ensuring the hull's balance, stability, and safety.

[0004] The aforementioned patent can automatically right the hull and improve its stability during navigation. However, the device requires the airbag to be inflated to prevent capsizing. During the inflation process, the hull may capsize because the airbag is not fully inflated, making it difficult to provide sufficient buoyancy. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a self-righting and anti-sinking inflatable boat, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a self-righting and anti-sinking inflatable boat, comprising an inflatable boat body, a partition plate installed on the inflatable boat body, a counterweight block installed on the inflatable boat body, a motor installed on the inflatable boat body, and a level detector installed on the inflatable boat body. The self-righting and anti-sinking inflatable boat also includes an anti-capsizing mechanism and a correction mechanism installed on the inflatable boat body. The anti-capsizing mechanism includes a rotating rod installed on the inflatable boat body and a telescopic rotating plate installed on the rotating rod. The anti-capsizing mechanism is used to improve the stability of the boat during navigation, increase the restoring torque to suppress rolling and tilting, reduce the risk of capsizing, reduce the swaying amplitude in wind and waves, and improve navigation comfort and safety. The correction mechanism includes a guide plate installed on the inflatable boat body and a sliding rod installed on the inflatable boat body. The correction mechanism is used to assist the boat in a horizontal state, can quickly lower the boat's center of gravity, enhance longitudinal and lateral stability, and increase the restoring torque.

[0007] The anti-capsulation mechanism also includes a threaded rod mounted on the motor, a connecting block mounted on the threaded rod, and a wing plate mounted on the rotating rod. The wing plate is used to deploy when the boat capsizes. When the level detector detects that the inflatable boat is capsizing during operation, it can significantly increase the lateral stability of the hull, enhance the recovery torque to suppress rolling and tilting, and reduce the risk of capsizing. After the wing plate is deployed, it forms a stable support, reduces the swaying amplitude in wind and waves, improves sailing comfort and safety, and at the same time helps to balance the hull, intervening in advance before the critical capsizing to avoid complete capsizing.

[0008] The correction mechanism also includes a counterweight two mounted on the sliding rod one and a propeller mounted on the inflatable boat body. The counterweight two is used to increase the instantaneous impact force to counteract the boat's capsizing force.

[0009] The connecting block is rotatably connected to the telescopic rotating plate, the guide plate is in contact with the second counterweight, and the wing plate is used to support the second counterweight. During the process of preventing capsizing, the second counterweight will generate a downward impact force as it falls, which can quickly lower the center of gravity of the ship, enhance longitudinal and lateral stability, increase the restoring torque, effectively suppress roll, pitch and roll, and prevent the ship from continuously losing stability and swaying in the wind and waves. At the same time, the impact force can actively apply a righting torque before the capsizing threshold, assist the ship to quickly right itself, reduce the probability of complete capsizing, and offset the capsizing force of the wind and waves through the inertial force generated by the fall, improve the wave resistance and anti-capsizing ability, ensure the safety of the crew and the stability of the equipment. At the same time, in conjunction with the wing plate, multiple stability protections are formed, making the ship more stable and safer in bad sea conditions, and significantly improving the reliability of survival and operation.

[0010] The anti-capsizing mechanism also includes a limiting mechanism installed on the inflatable boat body. The limiting mechanism includes a grooved plate installed on the inflatable boat body, a chamfered block installed on the wing plate, an elastic rod installed on the chamfered block, and an inclined block installed on the elastic rod. The inclined block is used to prevent the wing plate from retracting due to external force when it is deployed.

[0011] The limiting mechanism also includes a connecting rod mounted on the inflatable boat body via a torsion spring, a fixing ring mounted on the connecting rod, and a float mounted on the fixing ring. The float is used to unfold when the boat flips over. When the wing plate rotates to a suitable angle, the inclined block will be locked in the corresponding groove of the grooved plate, thereby fixing the unfolding angle of the wing plate. This allows the wing plate to maintain a preset support posture, preventing rebound, swaying, or excessive deflection when impacted by wind and waves or when the hull rolls. This ensures stable output of lateral stability and restoring torque, continuously suppresses roll and tilt, prevents instability and capsizing, ensures the stability of the wing plate support, improves wave resistance and sailing stability, and avoids reduced righting effect and secondary rolling caused by angle changes.

[0012] The grooved disc contacts the inclined block, and the grooved disc is used to limit the inclined block. The user can also push the buoy to the side of the ship through the handle on the buoy, which can greatly widen the lateral support width of the hull, increase the buoyancy center height and the recovery moment, significantly enhance the anti-roll and anti-rolling ability, reduce the risk of capsizing, and at the same time, the deployed buoy provides additional buoyancy reserve, improves the stability of the hull, suppresses the sway amplitude in wind and waves, avoids violent swaying that causes capsizing, and can also help balance the hull and distribute the load.

[0013] The limiting mechanism also includes an anti-clogging mechanism installed on the float. The anti-clogging mechanism includes a straight plate installed on the guide plate, a straight rod installed on the straight plate, a force-bearing block installed on the straight rod, and a trapezoidal plate installed on the force-bearing block. The trapezoidal plate is used to prevent water plants from clogging the surface of the propeller.

[0014] The anti-clogging mechanism also includes a U-shaped plate installed on the inflatable boat body, a sliding rod II installed on the U-shaped plate, a movable plate installed on the sliding rod II, and a locking rod installed on the movable plate. The locking rod is used to limit the position of the float. When improving the stability of the boat, the trapezoidal plate moves forward and contacts the water inlet of the propeller, which can remove impurities attached to the water inlet of the propeller, thereby ensuring smooth water flow and avoiding insufficient water flow due to blockage by water plants and debris. This prevents the propeller from experiencing power reduction, abnormal noise, or even burnout and shutdown, ensuring the continuous and stable operation of the power system, avoiding loss of control and capsizing of the boat due to power failure in harsh waters, extending the service life of the equipment, and reducing maintenance difficulty.

[0015] The buoy and the locking rod are in contact with each other. The surface of the straight rod is provided with a spring, which is used to push the force block to move. When the wing plate is retracted, the straight plate can support the bottom of the wing plate to improve the stability of the wing plate. When the hull is completely overturned, it can quickly generate eccentric buoyancy and righting torque in the overturned state, break the balanced overturned state, force the hull to rotate, assist the user in providing initial righting power, and avoid the hull being unable to return to its original position for a long time. The deployed buoy can increase local buoyancy, speed up the hull's righting speed, improve the self-rescue capability in extreme working conditions, and at the same time prevent the hull from sinking completely, thus improving the safety of use.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when the horizontal detector detects that the inflatable boat is about to capsize, it can significantly increase the lateral stability of the hull, enhance the restoring torque to suppress rolling and heeling, reduce the risk of capsizing, and form stable support after the wing plates are deployed, reducing the swaying amplitude in wind and waves, improving sailing comfort and safety. At the same time, it helps to balance the hull and intervenes in advance before the critical capsizing, avoiding complete overturning. In the process of preventing capsizing, the counterweight block two generates a downward impact force as it falls, which can quickly lower the center of gravity of the boat, enhance longitudinal and lateral stability, increase the restoring torque, effectively suppress rolling, pitching and heeling, and prevent the hull from continuously becoming unstable and swaying in wind and waves. At the same time, this impact force can actively apply a righting torque before the critical capsizing, assisting the hull to quickly right itself, reducing the probability of complete overturning, and offsetting the overturning force of wind and waves through the inertial force generated by the falling, improving the wave resistance and anti-capsizing ability, ensuring the safety of the crew and the stability of the equipment. At the same time, in conjunction with the wing plates, multiple stability protections are formed, making the boat more stable and safer in bad sea conditions, significantly improving survival and operational reliability.

[0017] 2. In this invention, when the wing plate rotates to a suitable angle, the inclined block will lock into the corresponding groove of the grooved plate, thereby fixing the angle of the wing plate deployment. This allows the wing plate to maintain a preset support posture, preventing rebound, swaying, or excessive deflection when impacted by wind and waves or when the hull rolls. This ensures stable output of lateral stability and restoring torque, continuously suppressing roll and heel, preventing instability and capsizing, ensuring the stability of the wing plate support, improving wave resistance and sailing stability, and preventing the righting effect from being reduced due to angle changes and causing secondary swaying. At the same time, the user can also push the buoy to the side of the ship using the handle on the buoy, thereby significantly widening the hull's lateral support width, increasing the center of buoyancy height and restoring torque, significantly enhancing the anti-roll and anti-heeling capabilities, reducing the risk of capsizing. The deployed buoy provides additional buoyancy reserves, improving hull stability, suppressing the sway amplitude in wind and waves, preventing violent swaying from causing capsizing, and also assisting in balancing the hull and distributing loads.

[0018] 3. In this invention, during the process of improving hull stability, the trapezoidal plate will contact the water inlet of the propeller as it moves forward, and can remove impurities attached to the water inlet of the propeller, thereby ensuring smooth water flow and avoiding insufficient water flow due to blockage by water plants and debris. This prevents the propeller from experiencing power reduction, abnormal noise, or even burnout and shutdown, ensuring the continuous and stable operation of the power system. It also prevents the hull from capsizing due to power failure in harsh waters, extends the service life of the equipment, and reduces maintenance difficulty. When the wing plate is retracted, the bottom of the wing plate can be supported by the straight plate to improve the wing plate's stability. When the hull is completely overturned, eccentric buoyancy and righting torque can be quickly generated in the overturned state, breaking the balanced overturned state and forcing the hull to rotate. This assists the user in providing initial righting power and prevents the hull from being unable to return to its original position for a long time. The deployed float can increase local buoyancy, accelerate the hull's righting speed, improve self-rescue capability in extreme working conditions, and prevent the hull from sinking completely, thus improving the safety of use.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please see Figures 1-5 One embodiment of the present invention is: a self-righting and anti-sinking inflatable boat, including an inflatable boat body 1, a partition plate 2 installed on the inflatable boat body 1, a counterweight block 3 installed on the inflatable boat body 1, a motor 4 installed on the inflatable boat body 1, and a level detector 5 installed on the inflatable boat body 1. When the level detector 5 detects that the inflatable boat body 1 has capsized during travel, the level detector 5 will start the motor 4 through an electrical signal. The self-righting and anti-sinking inflatable boat also includes an anti-capsulation mechanism and a correction mechanism installed on the inflatable boat body 1. The anti-capsizing mechanism includes a rotating rod 7 installed on the inflatable boat body 1 and a telescopic rotating plate 8 installed on the rotating rod 7. The anti-capsizing mechanism is used to improve the stability of the boat during the journey. When the boat body sways from side to side, it can significantly increase the lateral stability of the boat body and enhance the restoring torque to suppress rolling and tilting. The correction mechanism includes a guide plate 11 installed on the inflatable boat body 1 and a sliding rod 12 installed on the inflatable boat body 1. The correction mechanism is used to help the boat stay in a horizontal state, can quickly lower the center of gravity of the boat, enhance longitudinal and lateral stability, increase the restoring torque, effectively suppress roll, pitch and roll and avoid the boat from becoming unstable and swinging more in the wind and waves.

[0023] In this embodiment, when the level detector 5 detects that the inflatable boat body 1 has capsized during operation, the level detector 5 will start the motor 4 via an electrical signal. The start of the motor 4 will drive the threaded rod 6 to rotate. The rotation of the threaded rod 6 will drive the connecting block 9 to move backward through the threaded groove on its surface. During the backward movement of the connecting block 9, the telescopic rotating plate 8 will rotate. During the rotation of the telescopic rotating plate 8, the rotating rod 7 will rotate. When the rotating rod 7 rotates, the wing plate 10 will rotate synchronously. When the wing plate 10 rotates, it will unfold to both sides of the hull. In this way, when the hull sways from side to side, it can significantly increase the lateral stability of the hull, improve the restoring torque to suppress rolling and tilting, and reduce the risk of capsizing. After the wing plate 10 is unfolded, it forms a stable support, reduces the swaying amplitude in wind and waves, improves sailing comfort and safety, and at the same time helps to balance the hull. It intervenes in advance before the critical capsizing and avoids complete overturning.

[0024] The anti-capsulation mechanism also includes a threaded rod 6 mounted on the motor 4. The rotation of the threaded rod 6 will drive the connecting block 9 to move backward through the threaded groove on its surface. The connecting block 9 mounted on the threaded rod 6 and the wing plate 10 mounted on the rotating rod 7 are used to deploy when the boat capsizes. After the wing plate 10 is deployed, it forms a stable support, reduces the swaying amplitude in wind and waves, and improves navigation comfort and safety. When the rotating rod 7 rotates, it will drive the wing plate 10 to rotate synchronously.

[0025] The correction mechanism also includes a counterweight 13 mounted on the sliding rod 12 and a propeller 14 mounted on the inflatable boat body 1. The counterweight 13 is used to increase the instantaneous impact force to counteract the boat's capsizing force. When the counterweight 13 moves downward, it will cause the sliding rod 12 to move downward. During the downward fall of the counterweight 13, a downward impact force will be generated.

[0026] The connecting block 9 is rotatably connected to the telescopic rotating plate 8. When the connecting block 9 moves backward, it will drive the telescopic rotating plate 8 to rotate. The guide plate 11 and the second counterweight 13 are in contact with each other. The wing plate 10 is used to support the second counterweight 13. When the wing plate 10 unfolds, it will release the restriction on the second counterweight 13.

[0027] During the process of preventing capsizing, the deployment of wing plate 10 will release the restriction on counterweight block 13. At this time, counterweight block 13 will fall rapidly downwards under gravity. The downward movement of counterweight block 13 will drive sliding rod 12 to move downwards. During the downward fall of counterweight block 13, a downward impact force will be generated, which can quickly lower the center of gravity of the ship, enhance longitudinal and lateral stability, increase the restoring torque, effectively suppress roll, pitch and roll and avoid the ship from continuously losing stability and swaying in wind and waves. At the same time, this impact force can actively apply a righting torque before the capsizing threshold, assist the ship to quickly right itself, reduce the probability of complete capsizing, and offset the capsizing force of wind and waves through the inertial force generated by the fall, improve the resistance to waves and capsizing, ensure the safety of the crew and the stability of the equipment. At the same time, together with wing plate 10, multiple stability protections are formed, making the ship more stable and safer in bad sea conditions, significantly improving the reliability of survival and operation.

[0028] Example 2: Please see Figures 5-7 Based on the above embodiments, in another embodiment of the present invention, the anti-capsizing mechanism further includes a limiting mechanism 15 installed on the inflatable boat body 1. The limiting mechanism 15 includes a grooved plate 151 installed on the inflatable boat body 1, a chamfered block 152 installed on the wing plate 10, an elastic rod 153 installed on the chamfered block 152, and an inclined block 154 installed on the elastic rod 153. The rotation of the elastic rod 153 will drive the inclined block 154 to rotate. During the rotation of the inclined block 154, it will contact the bottom of the grooved plate 151. The inclined block 154 is used to prevent the wing plate 10 from retracting due to external force when it is deployed. It can fix the angle of the wing plate 10 when it is deployed, so that the wing plate 10 can maintain a preset support posture and avoid rebound, swaying or excessive deflection when the wind and waves hit or the hull sways. The rotation of the elastic rod 153 will drive the inclined block 154 to rotate. During the rotation of the inclined block 154, it will contact the bottom of the grooved plate 151.

[0029] The limiting mechanism 15 also includes a connecting rod 155 mounted on the inflatable boat body 1 by a torsion spring, a fixing ring 156 mounted on the connecting rod 155, and a float 157 mounted on the fixing ring 156. The float 157 is used to unfold when the boat is overturned. The movement of the float 157 will drive the fixing ring 156 to move, and the movement of the fixing ring 156 will push the connecting rod 155 to unfold.

[0030] The grooved disk 151 and the inclined block 154 are in contact with each other. The grooved disk 151 is used to limit the inclined block 154. When the inclined block 154 moves into the grooved disk 151, the inclined block 154 will be stuck inside the grooved disk 151. During the process of the inclined block 154 rotating out from the inclined groove of the grooved disk 151, the inclined block 154 will be subjected to the squeezing force of the inclined surface of the grooved disk 151, forcing the inclined block 154 to move downward.

[0031] In this embodiment, during the unfolding of the wing plate 10, the rotation of the wing plate 10 causes the chamfer block 152 to rotate. The rotation of the chamfer block 152 causes the elastic rod 153 to rotate, which in turn causes the inclined block 154 to rotate. During the rotation of the inclined block 154, it comes into contact with the bottom of the grooved disk 151. When the inclined block 154 contacts the notch of the grooved disk 151, the elastic rod 153 moves upward through the surface spring, which in turn causes the inclined block 154 to move synchronously. When the inclined block 154 moves into the grooved disk 151, it gets stuck inside. As the inclined block 154 rotates out of the grooved slot of the grooved disk 151, it is subjected to the squeezing force of the inclined surface of the grooved disk 151, forcing it to move downwards. This downward movement of the inclined block 154 causes the elastic rod 153 to move downwards and compresses the spring on the surface of the inclined block 154. When the wing plate 10 rotates to a suitable angle, the inclined block 154 will be stuck in the corresponding groove of the grooved disk 151, thus enabling the wing plate to rotate. The angle at which the wing plate 10 unfolds is fixed, thus maintaining the wing plate 10 in a preset supporting posture. This prevents rebound, swaying, or excessive deflection during wind and wave impacts and hull rolling, ensuring stable output of lateral stability and restoring torque. It continuously suppresses roll and heel, preventing instability and capsizing, ensuring the stability of the wing plate 10 support, improving wave resistance and sailing stability, and preventing the righting effect from decreasing and secondary rolling caused by angle changes. Additionally, the user can push the float 157 to the side of the ship using the handle on the float 157. The movement of the float 157 will cause the fixed ring 156 to move, and the movement of the fixed ring 156 will push the connecting rod 155 to unfold, thereby further improving the stability of the inflatable boat body 1. This will significantly widen the lateral support width of the hull, increase the buoyancy center height and the restoring moment, significantly enhance the anti-roll and anti-rolling capabilities, and reduce the risk of capsizing. At the same time, the unfolded float 157 provides additional buoyancy reserves, improves the stability of the hull, suppresses the swaying amplitude in wind and waves, avoids violent swaying that could cause capsizing, and can also help balance the hull and distribute the load.

[0032] Example 3: Please see Figures 7-9Based on the above embodiments, in another embodiment of the present invention, the limiting mechanism 15 further includes an anti-clogging mechanism 16 installed on the float 157. The anti-clogging mechanism 16 includes a straight plate 161 installed on the guide plate 11, a straight rod 162 installed on the straight plate 161, a force-bearing block 163 installed on the straight rod 162, and a trapezoidal plate 164 installed on the force-bearing block 163. The force-bearing block 163 will be pushed forward by the spring on the surface of the straight rod 162. The forward movement of the force-bearing block 163 will drive the trapezoidal plate 164 to move forward. The trapezoidal plate 164 is used to prevent water plants from clogging the surface of the propeller 14, thereby ensuring smooth water flow and avoiding insufficient water flow due to blockage by water plants and debris, and preventing the propeller 14 from experiencing power reduction, abnormal noise, or even burnout and shutdown.

[0033] In this embodiment, during the process of improving hull stability, the unfolding of the wing plate 10 releases the pressure on the force block 163. At this time, the force block 163 is pushed forward by the spring on the surface of the straight rod 162. The forward movement of the force block 163 drives the trapezoidal plate 164 forward. During the forward movement of the trapezoidal plate 164, it comes into contact with the water inlet of the propeller 14 and can remove impurities attached to the water inlet of the propeller 14, thereby ensuring smooth water flow and avoiding insufficient water flow due to blockage by weeds and debris. This prevents the propeller 14 from experiencing power reduction, abnormal noise, or even burnout and shutdown, ensuring the continuous and stable operation of the power system and avoiding damage in harsh waters. Force failure causes the hull to capsize out of control, extends the service life of equipment, and reduces maintenance difficulty. When the wing plate 10 is retracted, the wing plate 10 will contact the front of the force block 163 during rotation and push the force block 163 backward through the squeezing force. During the backward movement of the force block 163, the trapezoidal plate 164 will move synchronously. During the movement of the force block 163, the spring set on the surface of the straight rod 162 will be compressed, thereby storing force to push the force block 163 to move. After the wing plate 10 is fully retracted, the wing plate 10 will be at the top of the straight plate 161, and the bottom of the wing plate 10 can be supported by the straight plate 161 to improve the stability of the wing plate 10.

[0034] The anti-clogging mechanism 16 also includes a U-shaped plate 165 installed on the inflatable boat body 1, a sliding rod 166 installed on the U-shaped plate 165, a movable plate 167 installed on the sliding rod 166, and a locking rod 168 installed on the movable plate 167. The locking rod 168 is used to limit the float 157. When the movable plate 167 moves downward, it will drive the locking rod 168 to move downward. When the locking rod 168 moves downward, it will completely leave the interior of the connecting rod 155, thereby releasing the limitation on the front connecting rod 155.

[0035] The float 157 is in contact with the locking rod 168. The rotation of the connecting rod 155 will cause the front float 157 to unfold, so that the float 157 can be automatically unfolded when the boat capsizes. The surface of the straight rod 162 is provided with a spring, which is used to push the force block 163 to move. During the movement of the force block 163, the spring provided on the surface of the straight rod 162 will be compressed, thereby storing force to push the force block 163 to move. During the backward movement of the force block 163, the trapezoidal plate 164 will move synchronously. When the force block 163 moves forward, the trapezoidal plate 164 will move forward.

[0036] When the hull completely capsizes, the movable plate 167 will move downwards under gravity. The downward movement of the movable plate 167 will drive the locking rod 168 to move downwards. The downward movement of the locking rod 168 will completely leave the interior of the connecting rod 155, thereby releasing the restriction on the front connecting rod 155. At this time, the connecting rod 155 will rotate through the torsion spring. The rotation of the connecting rod 155 will drive the front float 157 to unfold. Thus, when the hull capsizes, one side float 157 can be automatically unfolded, thereby quickly generating eccentric buoyancy and righting torque in the capsized state, breaking the balanced capsized state, forcing the hull to have a tendency to rotate, assisting the user in providing initial righting power, and preventing the hull from being unable to return to its original position for a long time. The unfolded float 157 can increase local buoyancy, speed up the hull's righting speed, improve the self-rescue capability in extreme working conditions, and at the same time prevent the hull from sinking completely, improving the safety of use.
