Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a small boat recovery and release device. Background Technology

[0002] In the field of marine technology, various mother ships carrying small boats (such as rescue ships, work ships, etc.) often need to use small boats to perform tasks such as water rescue, material transportation, and on-site reconnaissance. As a key connecting device between the mother ship and the small boat, the stability, efficiency and environmental adaptability of the small boat recovery and release device directly affect the overall mission execution capability of the mother ship.

[0003] However, existing small boat recovery and release devices have the following drawbacks: First, the interruption of the passage between the stern extension component and the mother ship causes impacts when the small boat moves, affecting operational efficiency; second, some stern components are difficult to fix stably to the mother ship, thus they are prone to shaking during navigation, posing safety hazards; third, the small boat's recovery and release drive relies on non-dedicated structures such as cranes and small boat self-drive, thus being greatly affected by hydrological and meteorological conditions and lacking stability.

[0004] Therefore, there is an urgent need for a small boat recovery and release device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a small boat recovery and release device that can more stably and safely recover and release small boats.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A small boat recovery and release device, comprising:

[0008] The folding mechanism includes a folding drive and a folding stern door. The folding drive can drive the folding stern door to rotate relative to the mother ship. The mother ship is provided with a retraction slide. When the folding stern door is in the unfolded state, the folding stern door and the retraction slide form a continuous sliding path. When the folding stern door is in the folded state, the folding stern door can be locked to the mother ship.

[0009] The launching and retracting mechanism includes a launching and retracting driver and a drive wheel assembly disposed on the sliding path. The launching and retracting driver can drive the drive wheel assembly to rotate. When the drive wheel assembly rotates, it can drive the small boat into or out of the sliding path.

[0010] Optionally, the folding stern door is rotatably connected to the mother ship about a horizontal axis, the folding actuator is rotatably connected to the mother ship, and the telescopic output end of the folding actuator is rotatably connected to the folding stern door.

[0011] Optionally, when the folding stern door is in the unfolded state, it can reach the small boat when the mother ship is in its minimum draft.

[0012] Optionally, the small boat recovery and release device further includes a locking mechanism, wherein when the folding stern door is in the folded state, the output end of the locking mechanism can extend to lock the folding stern door.

[0013] Optionally, when the drive wheel set rotates forward, it can drive the small boat in the sliding path to move towards the mother ship, and when the drive wheel set rotates in reverse, it can drive the small boat in the sliding path to move away from the mother ship.

[0014] Optionally, the drive wheel set includes multiple sets of drive wheel pairs spaced apart along the extension direction of the sliding path. Each drive wheel pair includes a first drive wheel and a second drive wheel that face each other and are spaced apart. The axis of the first drive wheel and the axis of the second drive wheel are set at an angle.

[0015] Optionally, the end of the folding stern door furthest from the mother ship is provided with a guide.

[0018] Optionally, the small boat recovery and release device further includes a recovery mechanism, the output end of which is detachably connected to the small boat.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a small boat recovery and release device, comprising a folding mechanism and a launch mechanism. The folding mechanism includes a folding actuator and a folding stern door. The folding actuator drives the folding stern door to rotate relative to the mother ship, achieving stable actuation of the folding stern door to facilitate the subsequent construction of a continuous sliding passage. The mother ship is equipped with a launch and recovery ramp. When the folding stern door is in the unfolded state, it forms a continuous sliding passage with the launch and recovery ramp, improving the smoothness of the small boat's entry and exit from the sliding passage and preventing damage to the hull due to large impacts during launch and recovery. When the folding stern door is in the folded state, it can be locked to the mother ship, ensuring the stability of the overall structure in the folded state. The launch and recovery mechanism includes a launch and recovery actuator and a drive wheel assembly disposed in the sliding passage. The launch and recovery actuator drives the drive wheel assembly to rotate. When the drive wheel assembly rotates, it can propel the small boat into or out of the sliding passage, thereby providing a stable and controllable power source for the launch and recovery of the small boat and avoiding loss of control due to hydrological and meteorological conditions. With the above-mentioned configuration, the small boat recovery and release device of this application can achieve the recovery and release of small boats more stably and safely.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] In the field of marine technology, various mother ships carrying small boats (such as rescue ships, work ships, etc.) often need to use small boats to perform tasks such as water rescue, material transportation, and on-site reconnaissance. As a key connecting device between the mother ship and the small boat, the stability, efficiency and environmental adaptability of the small boat recovery and release device directly affect the overall mission execution capability of the mother ship.

[0033] However, existing small boat recovery and release devices have the following drawbacks: First, the interruption of the passage between the stern extension component and the mother ship causes impacts when the small boat moves, affecting operational efficiency; second, some stern components are difficult to fix stably to the mother ship, thus they are prone to shaking during navigation, posing safety hazards; third, the small boat's recovery and release drive relies on non-dedicated structures such as cranes and small boat self-drive, thus being greatly affected by hydrological and meteorological conditions and lacking stability.

[0034] Therefore, there is an urgent need for a small boat recovery and release device to solve the above-mentioned technical problems.

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-5 As shown, this embodiment provides a small boat recovery and release device, which includes a folding mechanism 1 and a launch and recovery mechanism 2. The folding mechanism 1 includes a folding driver 11 and a folding stern door 12. The folding driver 11 can drive the folding stern door 12 to rotate relative to the mother ship 100. The mother ship 100 is provided with a launch and recovery slide 101. When the folding stern door 12 is in the unfolded state, the folding stern door 12 and the launch and recovery slide 101 form a continuous sliding passage. When the folding stern door 12 is in the folded state, the folding stern door 12 can be locked to the mother ship 100. The launch and recovery mechanism 2 includes a launch and recovery driver and a drive wheel assembly 21 disposed in the sliding passage. The launch and recovery driver can drive the drive wheel assembly 21 to rotate. When the drive wheel assembly 21 rotates, it can drive the small boat 200 to enter or slide out of the sliding passage.

[0037] In this embodiment, the folding mechanism 1 includes a folding actuator 11 and a folding stern door 12. The folding actuator 11 can drive the folding stern door 12 to rotate relative to the mother ship 100, thereby achieving stable driving of the folding stern door 12 to facilitate the subsequent construction of a continuous sliding passage. The mother ship 100 is provided with a retraction slide 101. When the folding stern door 12 is in the unfolded state, the folding stern door 12 and the retraction slide 101 form a continuous sliding passage, thereby improving the smoothness of the small boat 200 entering and exiting the sliding passage and preventing damage to the hull of the small boat 200 due to large impacts during retraction and deployment. When the folding stern door 12 is in the folded state, the folding stern door 12 can be locked to the mother ship 100, ensuring the stability of the overall structure in the folded state. The launching and retrieval mechanism 2 includes a launching and retrieval driver and a drive wheel assembly 21 disposed in the sliding passage. The launching and retrieval driver can drive the drive wheel assembly 21 to rotate. When the drive wheel assembly 21 rotates, it can drive the small boat 200 into or out of the sliding passage, thereby providing a stable and controllable power source for the launching and retrieval of the small boat 200 and avoiding loss of control due to hydrological and meteorological conditions. With the above configuration, the small boat retrieval and release device of this embodiment can achieve the retrieval and release of the small boat 200 more stably and safely.

[0038] The specific structure of the small boat recovery and release device is described below:

[0039] Specifically, the launching and retracting slide 101 is set at an angle of 10° to 15° with the horizontal direction. This ensures that the boat 200 can glide smoothly under its own weight and the power of the drive wheel assembly 21, improving launching and retracting efficiency. It also prevents the boat 200 from losing control of its speed and causing impacts due to an excessively large angle, while avoiding insufficient gliding power due to an excessively small angle. In this embodiment, the angle between the launching and retracting slide 101 and the horizontal direction is 12°, balancing the launching and retracting efficiency and safety of the boat 200. In other embodiments, the angle between the launching and retracting slide 101 and the horizontal direction can also be 10°, 13°, or 15°, as long as the above-mentioned functions are achieved.

[0040] Specifically, the folding stern door 12 is rotatably connected to the mother ship 100 around a horizontal axis, the folding actuator 11 is rotatably connected to the mother ship 100, and the telescopic output end of the folding actuator 11 is rotatably connected to the folding stern door 12, so that the telescopic force of the folding actuator 11 can be stably converted into the rotational force of the folding stern door 12, ensuring the smooth operation of the folding stern door 12.

[0041] More specifically, the folding actuator 11 can be either a hydraulic cylinder or an electric actuator. Hydraulic cylinders have high driving force and can adapt to harsh navigation environments, while electric actuators offer high control precision and are easy to install. They can provide reliable driving force for the folding stern door 12 and allow for selection of a suitable drive type based on the operational needs of the mother ship 100. The specific structure of the folding actuator 11 will not be limited here, as long as it can achieve the above-mentioned functions.

[0042] Specifically, when the folding stern gate 12 is in the unfolded state, it can reach the small boat 200 when the mother ship 100 is in its minimum draft state. This ensures that the mother ship 100 can still effectively connect with the small boat 200 through the folding stern gate 12 in shallow water or empty water scenarios with minimum draft, so as to realize the launching and retrieving of the small boat 200. This improves the adaptability of the device to different hydrological environments and avoids problems such as the folding stern gate 12 being unable to reach the small boat 200 and the launch and retrieving operation being interrupted due to the mother ship 100 having too shallow a draft.

[0043] Specifically, the small boat recovery and release device also includes a sensor probe and a control mechanism. The sensor probe is communicatively connected to the folding drive 11 and the control mechanism, and can detect the position information of the folding stern door 12 and transmit the position information to the control mechanism. The control mechanism can control the folding drive 11 to move based on the position information of the folding stern door 12, thereby achieving precise control of the rotation position of the folding stern door 12.

[0044] The sensing probe can be a photoelectric sensor or a proximity switch. The control mechanism can be a PLC controller or a microcontroller. Photoelectric sensors offer high detection accuracy and strong anti-interference capabilities, while proximity switches are easy to install and have a fast response speed. PLC controllers offer flexible programming and adaptability to multi-device linkage, while microcontrollers are small in size and low in cost. It is understood that the specific structure of the above components is not strictly limited, as long as they can achieve the aforementioned functions.

[0045] Specifically, the small boat recovery and release device also includes a locking mechanism. When the folding stern door 12 is in the folded state, the output end of the locking mechanism can extend to lock the folding stern door 12. The locking mechanism can be a locking cylinder, an electromagnetic lock, or a mechanical pin, ensuring that the folding stern door 12 is stably fixed to the mother ship 100 after being in the folded state. The specific structure of the locking mechanism is not described in detail here, and those skilled in the art are familiar with its working principle; therefore, it will not be elaborated further.

[0046] Specifically, when the drive wheel assembly 21 rotates forward, it can move the small boat 200 in the sliding path towards the mother ship 100; when the drive wheel assembly 21 rotates in reverse, it can move the small boat 200 in the sliding path away from the mother ship 100. It can be understood that the rubber treads on the drive wheel assembly 21 increase the friction with the small boat 200, thereby retrieving the small boat 200 back to the mother ship 100. The simple switching of the drive wheel assembly 21's direction allows for the conversion between retrieving and releasing the small boat 200, making operation more convenient and efficient.

[0047] More specifically, in this embodiment, the launch and retraction actuator is a hydraulic motor used to drive the drive wheel assembly 21 to rotate, providing a continuous and stable driving force to the drive wheel assembly 21 and ensuring the uniform launch and retraction of the small boat 200. In other embodiments, the launch and retraction actuator is an electric motor or a pneumatic motor, which can also achieve the above-mentioned function. The specific structure of the launch and retraction actuator is not limited here.

[0048] More specifically, the drive wheel assembly 21 includes multiple sets of drive wheel pairs spaced apart along the extension direction of the sliding path. This arrangement ensures that the small boat 200 receives a uniform driving force throughout the sliding path. Furthermore, each drive wheel pair includes a first drive wheel 211 and a second drive wheel 212 arranged opposite each other and spaced apart. The axes of the first drive wheel 211 and the second drive wheel 212 are angled together. It can be understood that the axes of the first drive wheel 211 and the second drive wheel 212 form a V-shape, thus providing lateral restraint on both sides of the small boat 200. This ensures that the small boat 200 always moves along the centerline of the sliding path during sliding, preventing the small boat 200 from deviating or colliding due to water flow disturbances or drive deviations. Simultaneously, this arrangement allows for adaptation to different types of small boats 200, increasing the adaptability and enhancing operability.

[0049] Specifically, the end of the folding stern door 12 away from the mother ship 100 is provided with a guide 121, which can provide preliminary guidance to the small boat 200 before it enters the taxiway, guiding the small boat 200 to accurately align with the entrance of the taxiway.

[0050] More specifically, in this embodiment, the guide member 121 is a guide post, and there are two guide posts. The two guide posts face each other and are spaced apart. The small boat 200 can pass between the two guide posts and enter and exit the sliding passage. The two guide posts can form symmetrical guidance on both sides of the small boat 200, further improving the guidance accuracy. In other embodiments, the guide member 121 is a guide plate. The specific structure of the guide member 121 is not limited here, as long as it can achieve the above-mentioned functions.

[0051] Specifically, the guide component 121 is equipped with an indicator light 122, which allows the operators of the small boat 200 to monitor the operating status of the device in real time, thereby adjusting the attitude of the small boat 200 in a timely manner. This not only improves the safety of the operators but also reduces the risk of damage to the device and avoids the small boat 200 from going out of control and colliding with the mother ship 100 due to unclear information.

[0052] Specifically, the small boat recovery and release device also includes a sensing mechanism, which is used to determine the position of the small boat 200 in the sliding path and can control the rotation speed of the drive wheel assembly 21. The sensing mechanism can be an ultrasonic sensor switch, an infrared sensor switch, or a laser rangefinder sensor to accurately determine the position of the small boat 200. The specific structure of the sensing mechanism is not limited here, as long as it can achieve the above-mentioned functions.

[0053] More specifically, the mother ship 100 is equipped with a limiting component. When the small boat 200 enters the sliding passage, the limiting component can abut against the small boat 200 to achieve a limiting function and prevent the sensing mechanism from malfunctioning. The limiting component can be a limiting block or a limiting pier, etc., and no further restrictions are imposed here.

[0054] Specifically, the small boat recovery and release device also includes a recovery mechanism 3, which is used to recover the small boat 200. The output end of the recovery mechanism 3 is detachably connected to the small boat 200, and can quickly connect to the small boat 200 when needed, thereby starting the recovery operation of the small boat 200, which improves the flexibility of the device.

[0055] More specifically, in this embodiment, the recovery mechanism 3 is a hydraulic winch. The output end of the hydraulic winch is connected to the small boat 200 via a rope. When the drive wheels fail and cannot rotate, the hydraulic winch can be used to recover the small boat 200, preventing it from remaining on the water surface and becoming unrecoverable, thus improving the reliability and emergency response capability of the device. In other embodiments, the recovery mechanism 3 is an electric winch or a pneumatic winch, which can also achieve the above functions. No further limitations are placed on the structure described above.

[0056] The following describes the operation of the small boat recovery and release device:

[0057] Release process of small boat 200: Folding drive 11 drives folding stern door 12 to rotate relative to mother ship 100, so that folding stern door 12 is in the unfolded state, so that folding stern door 12 and retraction slide 101 form a continuous sliding path. Warning light is turned on to indicate that the personnel of small boat 200 and mother ship 100 are ready. Retraction drive drives drive wheel set 21 to reverse, so that small boat 200 gradually moves away from mother ship 100 and slides out along the inclined sliding path, thus completing the release.

[0058] The recovery process of the small boat 200: The folding actuator 11 drives the folding stern door 12 to rotate relative to the mother ship 100, so that the folding stern door 12 is in the unfolded state, allowing the small boat 200 to smoothly enter the sliding passage. Then, the warning light is turned on to prompt the operators to start the recovery operation. The small boat 200 approaches the folding stern door 12 to enter the sliding passage, and corrects its direction through the guide 121. The position of the small boat 200 is detected by the sensing mechanism, and the drive wheel set 21 is controlled to rotate forward, so that the small boat... The small boat 200 approaches the mother ship 100 along the inclined sliding path. When the small boat 200 touches the limiting component, the drive wheel assembly 21 stops rotating, and the folding actuator 11 drives the folding stern door 12 to rotate relative to the mother ship 100. When the folding stern door 12 approaches the vertical position, the sensor probe positions and controls the folding stern door 12 to stop through the control mechanism, so that the folding stern door 12 is in the unfolded state. At this time, the locking cylinder extends to lock the folding stern door 12, thereby realizing the recovery operation of the small boat 200. When the drive wheel assembly 21 fails, the recovery mechanism 3 is activated to directly pull the small boat 200 for recovery.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
