Description

Technical Field

[0001] The present invention relates to the technical field of rescue boats, and in particular to a rescue boat with high stability. Background Art

[0002] Rescue vessels, as the core equipment of the aquatic emergency rescue system, are a crucial lifeline for humanity in the face of crises in oceans, rivers, and other waterways. Designed with "rapid response, efficient rescue, and safety and reliability" in mind, these specialized vessels integrate expertise from diverse fields, including naval engineering, fluid dynamics, and emergency rescue technology. Their functional positioning and technical configuration are centered around the ultimate goal of "saving life and property in extreme environments." Their purpose is to rapidly rescue endangered individuals, vessels, or other aquatic facilities, minimizing loss of life and property. They are typically equipped with advanced navigation and communication equipment, life-saving equipment, salvage equipment, and a professional rescue team.

[0003] Referring to the reference document, publication number CN213832063U, the present invention provides a firefighting and rescue boat for ice and swampland, relating to the technical field of firefighting and rescue boats. The firefighting and rescue boat for ice and swampland includes a rescue boat hull structure, comprising a rescue boat hull, a screw propulsion auger, floats, and a bracket. The rescue boat hull is equipped with a screw propulsion auger on both sides for propelling the rescue boat hull, and multiple floats are provided on both sides of the rescue boat hull, connected to the rescue boat hull via brackets. The firefighting and rescue boat for ice and swampland provided by the present invention has the advantages of being compact and having low energy consumption.

[0004] Existing rescue boats usually encounter turbulent or rapid waters when in use. At present, most rescue boats on the market tend to focus on the installation of rescue equipment and the realization of rescue functions during the design and construction process, but pay insufficient attention to the configuration of navigation stability devices. The hull structure design of traditional rescue ships is more based on the needs of navigation in conventional waters. Its ship type, center of gravity distribution and wind and wave resistance are difficult to effectively cope with the extreme forces brought by turbulence and rapids. When the rescue ship enters turbulent or rapid waters, the hull is instantly faced with complex and powerful external force impacts. The surging waves will produce high-frequency and large-amplitude forces on the hull from different directions, causing the hull to shake violently. At the rescue operation level, the violent shaking seriously interferes with the normal operation of the rescue equipment. For medical first aid work that needs to be carried out on the deck, the shaking environment makes it difficult for medical staff to maintain balance and unable to perform medical operations accurately, which may delay the treatment of the wounded. At the same time, when the hull shakes, the rescue personnel have great inconvenience in moving and it is difficult to transfer to the rescue target location quickly and safely, which seriously affects the rescue efficiency and success rate. When the hull shakes violently, it may also cause the hull to capsize, affecting the safety of the rescue. Summary of the Invention

[0005] The purpose of the present invention is to provide a rescue boat with high stability to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a rescue boat with high stability, comprising a hull, a propeller installed on the outer wall of the hull, the tail of the hull is fixedly connected to a mounting platform, and a swing mechanism is provided on the mounting platform, wherein the swing mechanism comprises side plates fixedly connected to both sides of the mounting platform, the outer walls of the two side plates are fixedly connected to a hydraulic telescopic rod, the ends of the two hydraulic telescopic rods are commonly fixedly connected to a movable plate, the outer wall of the movable plate is rotatably connected to a rotating shaft, both sides of the rotating shaft are fixedly connected to a limiting protrusion, both sides of the mounting platform are fixedly connected to a baffle, the baffle is located on the side of the limiting protrusion, a steel pipe is fixedly connected to the outer wall of the rotating shaft, the end of the steel pipe away from the rotating shaft is fixedly connected to a cylinder, a plurality of counterweights are fixedly connected to the cylinder, and an addition port is provided on the cylinder.

[0007] Through the setting of the above scheme, when the hull encounters turbulence or rapids, the cylinder lags behind the hull's shaking due to inertia, and a reverse swinging torque is formed through the steel pipe and the rotating shaft to offset the hull's rolling energy. The hydraulic telescopic rod can dynamically adjust the position of the movable plate according to the water conditions, change the swing radius and damping coefficient of the cylinder, and realize active anti-roll control.

[0008] Preferably, a deceleration groove is provided on the movable plate, contact plates are fixedly connected to both sides of the deceleration groove, a pressure rod is fixedly connected to the back side of the movable plate, and swing arms are rotatably connected to both sides of the pressure rod.

[0009] Through the setting of the above scheme, when the hull sways left and right, the pressure rod moves down with the movable plate, pushing the swing arm to expand to both sides, driving the skateboard to expand outward synchronously, increasing the lateral width of the waterline surface at the rear of the hull. The expanded skateboard produces relative movement with the water flow, forming water resistance and lift, and suppressing the roll amplitude.

[0010] Preferably, side rails are provided on both sides of the bottom of the mounting platform, and slides are slidably connected to the inside of the side rails on both sides, a boss is fixedly connected to the outer wall of the slide, a turntable is fixedly connected to the outer wall of the boss, and the end of the swing arm away from the pressure rod is rotatably connected to the turntable.

[0011] Through the setting of the above solution, during normal navigation, the skateboard is retracted into the side rail and is flush with the tail of the hull to avoid direct impact from the water flow.

[0012] Preferably, both sides of the rotating shaft are fixedly connected with a mounting box, and an adaptive adjustment mechanism is provided inside the mounting box.

[0013] Preferably, the adaptive adjustment mechanism includes a moving block that slides through the inside of the installation box, the contact surfaces of the moving block and the speed reduction groove are made of frosted material, and connecting plates are fixedly connected on both sides of the moving block, and pressure springs are fixedly connected on the outer walls of the connecting plates on both sides, and the end of the pressing spring away from the connecting plate is fixedly connected to the inner wall of the installation box, and a downward pressure piece is fixedly connected to the outer wall of the moving block.

[0014] Through the setting of the above scheme, when the hull shakes violently and causes the cylinder to swing greatly, the moving block moves toward the speed reduction groove under the push of the positioning plate, and its frosted material contact surface fits with the inner wall of the speed reduction groove, generating high friction torque, which significantly increases the rotational resistance of the cylinder.

[0015] Preferably, an outer frame is fixedly connected to the outer wall of the installation box, a positioning plate is slidably connected to the outer frame, a bottom plate is fixedly connected to the outer side of the positioning plate, a return spring is fixedly connected to the outer wall of the bottom plate, one end of the return spring away from the bottom plate is fixedly connected to the outer wall of the outer frame, and the end of the positioning plate is rotatably connected to a roller.

[0016] Preferably, a plurality of positioning teeth are fixedly connected to the outer wall of the positioning plate, a mounting block is fixedly connected to the outer wall of the outer frame, an insert plate is slidably connected to the mounting block, mounting plates are fixedly connected on both sides of the insert plate, tension springs are fixedly connected to the mounting plates on both sides, one end of the tension spring away from the mounting plate is fixedly connected to the outer wall of the mounting block, vertical plates are fixedly connected on both sides of the insert plate, and the ends of the vertical plates on both sides are commonly connected to trigger magnets.

[0017] Preferably, electromagnets are embedded on both sides of the deceleration groove, and the magnetic poles of the electromagnets are the same as the magnetic poles of the trigger magnet.

[0018] Through the setting of the above scheme, when the bottom of the plug plate contacts the inclined surface of the positioning tooth, allowing the positioning plate to move unidirectionally to the specified position, the plug plate presses against the right-angled edge of the positioning tooth, forming a mechanical lock to prevent the damping from being released prematurely due to the rebound of the cylinder. Under the impact of continuous strong waves, this design can ensure that the adaptive adjustment mechanism remains activated and avoid intermittent failure of the damping.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Through the arrangement of mechanisms such as the skateboard and the cylinder, when the hull encounters a slight left-right sway caused by turbulence, the hydraulic telescopic rod drives the skateboard to unfold, increasing the lateral width of the rear waterline. The relative movement of the skateboard and the water flow generates water resistance and lift, thereby suppressing the roll amplitude. At the same time, the cylinder lags behind the movement of the hull due to inertia, and generates a reverse inertia torque through the steel pipe and the rotating shaft, which cooperates with the skateboard to achieve dual-source energy dissipation, thereby ensuring the stability of the entire hull. When rescuing in a turbulent environment, the hull can travel smoothly and ensure the rescue effect. The stable travel of the hull not only ensures that medical personnel can carry out medical first aid work on the hull, but also allows rescue personnel to quickly and safely transfer to the rescue target location, ensuring the efficiency and success rate of rescue.

[0021] 2. Through the setting of mechanisms such as the moving block, when the hull shakes violently, the rotating shaft will swing significantly, driving the positioning plate to hit the contact plate. Through the cooperation of the plug plate and the positioning tooth, the moving block is forced to contact the speed reduction groove, and the friction resistance of the frosted surface is used to automatically increase the swing resistance of the cylinder and reduce the swing speed. The entire adaptive adjustment mechanism can automatically adjust the resistance according to the degree of hull shaking. During slight shaking, the low resistance state is maintained to reduce unnecessary energy loss and ensure that the cylinder can play its normal anti-rolling role. When encountering large turbulence or rapids causing violent shaking, the resistance is automatically increased to achieve "on-demand adjustment". This adaptive feature enables the hull to maintain a good anti-rolling effect in different water conditions. It always remains stable in the changing rescue environment and provides a reliable platform for rescue operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] Example 1: Please refer to Figure 1 - Figure 9 A rescue boat with high stability includes a hull 1, a propeller 2 is installed on the outer wall of the hull 1, a mounting platform 3 is fixedly connected to the tail of the hull 1, and a swing mechanism is provided on the mounting platform 3. The swing mechanism includes side plates 5 fixedly connected to both sides of the mounting platform 3, and the outer walls of the two side plates 5 are fixedly connected to hydraulic telescopic rods 4. The ends of the two hydraulic telescopic rods 4 are fixedly connected to a movable plate 6. The outer wall of the movable plate 6 is rotatably connected to a rotating shaft 8, and both sides of the rotating shaft 8 are fixedly connected to limiting protrusions 9. Both sides of the mounting platform 3 are fixedly connected to baffles 7, and the baffles 7 are located on the side of the limiting protrusion 9. A steel pipe 10 is fixedly connected to the outer wall of the rotating shaft 8, and the end of the steel pipe 10 away from the rotating shaft 8 is fixedly connected to a cylinder 11. A plurality of counterweights 12 are fixedly connected to the cylinder 11, and an adding port 13 is opened on the cylinder 11.

[0034] A deceleration groove 14 is provided on the movable plate 6 , and contact plates 21 are fixedly connected to both sides of the deceleration groove 14 . A pressure rod 15 is fixedly connected to the back side of the movable plate 6 , and swing arms 19 are rotatably connected to both sides of the pressure rod 15 .

[0035] Side rails 16 are provided on both sides of the bottom of the mounting platform 3, and slides 17 are slidably connected to the inside of the side rails 16 on both sides. A boss 18 is fixedly connected to the outer wall of the slide 17, and a turntable 20 is fixedly connected to the outer wall of the boss 18. The end of the swing arm 19 away from the pressure rod 15 is rotatably connected to the turntable 20.

[0036] In this embodiment, when the hull 1 encounters turbulence or rapids during the rescue process, causing the entire hull 1 to sway left and right, the operator can control the two hydraulic telescopic rods 4 to extend. When the two hydraulic telescopic rods 4 are extended, they will push the movable plate 6 to move downward. When the movable plate 6 moves downward, the pressure rod 15 located on the back thereof will also move downward synchronously. At this time, under the movement and pressure of the pressure rod 15, the two swing arms 19 will be unfolded to both sides, thereby allowing the two slide plates 17 to move synchronously outward through the turntable 20 and the boss 18. When the two slide plates 17 are unfolded to both sides, the lateral width of the waterline surface at the rear of the entire hull 1 increases. When the two unfolded slide plates 17 sway left and right with the hull 1, they will produce relative motion with the water flow, forming water resistance and lift, thereby suppressing the roll amplitude. Since the cylinder 11 is filled with a lot of iron sand and is heavy, when the hull 1 is swaying left and right, the cylinder 11 is temporarily not in a state of inertia. It follows the movement of the hull 1, thus lagging behind the shaking of the hull 1. This lag causes the cylinder 11 and the steel pipe 10 to generate a pulling force on the hull 1 in the opposite direction of the shaking, and this pulling force forms a reaction torque through the rotating shaft 8, acting on the hull 1 to offset part of the force that makes the hull 1 shake, thereby reducing the shaking amplitude of the hull 1. Through the arrangement of the slide 17 and the cylinder 11 and other mechanisms, it can be achieved that when the hull 1 encounters a small left and right shaking caused by turbulence, the hydraulic telescopic rod 4 drives the slide 17 to unfold, increasing the lateral width of the tail waterline surface, and generating water resistance and lift through the relative movement of the slide 17 and the water flow to suppress the rolling amplitude. At the same time, the cylinder 11 lags behind the movement of the hull 1 due to inertia, and generates a reverse inertia torque through the steel pipe 10 and the rotating shaft 8, cooperating with the slide 17 to achieve dual-source energy dissipation, thereby ensuring the stability of the entire hull 1, allowing the hull 1 to travel smoothly during rescue in a turbulent environment, thereby ensuring the rescue effect.

[0037] Example 2: Please refer to Figure 1 - Figure 9 Both sides of the rotating shaft 8 are fixedly connected with a mounting box 22, and an adaptive adjustment mechanism is provided inside the mounting box 22.

[0038] The adaptive adjustment mechanism includes a moving block 23 that slides through the inside of the installation box 22. The contact surfaces of the moving block 23 and the speed reduction groove 14 are made of frosted material. Connecting plates 24 are fixedly connected on both sides of the moving block 23. Pressing springs 25 are fixedly connected to the outer walls of the connecting plates 24 on both sides. The end of the pressing spring 25 away from the connecting plate 24 is fixedly connected to the inner wall of the installation box 22, and a downward pressure piece 26 is fixedly connected to the outer wall of the moving block 23.

[0039] An outer frame 27 is fixedly connected to the outer wall of the mounting box 22, a positioning plate 28 is slidably connected to the outer frame 27, a bottom plate 37 is fixedly connected to the outer side of the positioning plate 28, a return spring 38 is fixedly connected to the outer wall of the bottom plate 37, one end of the return spring 38 away from the bottom plate 37 is fixedly connected to the outer wall of the outer frame 27, and the end of the positioning plate 28 is rotatably connected to a roller 29.

[0040] A plurality of positioning teeth 31 are fixedly connected to the outer wall of the positioning plate 28, a mounting block 33 is fixedly connected to the outer wall of the outer frame 27, an insert plate 30 is slidably connected to the mounting block 33, mounting plates are fixedly connected on both sides of the insert plate 30, tension springs 32 are fixedly connected to the mounting plates on both sides, the end of the tension spring 32 away from the mounting plate is fixedly connected to the outer wall of the mounting block 33, vertical plates 34 are fixedly connected on both sides of the insert plate 30, and the ends of the vertical plates 34 on both sides are commonly connected to the trigger magnet 36.

[0041] Electromagnets 35 are embedded on both sides of the speed reduction groove 14 , and the magnetic poles of the electromagnets 35 are the same as those of the trigger magnet 36 .

[0042] In this embodiment, when the hull 1 encounters large turbulence or rapids during the rescue process, causing the entire hull 1 to shake violently from side to side, the hysteresis swing amplitude of the steel pipe 10 and the cylinder 11 will be large. When the cylinder 11 swings greatly, the rotation amplitude of the rotating shaft 8 will also increase. When the rotating shaft 8 rotates greatly, it will synchronously drive the positioning plate 28 to rotate greatly. At this time, the end of the positioning plate 28 will hit the contact plate 21. Under the action of the impact, the positioning plate 28 will overcome the elastic force of the return spring 38 and move towards the installation box 22. When the positioning plate 28 moves towards the installation box 22, the bottom of the inserting plate 30 will continuously contact the inclined surfaces of multiple positioning teeth 31 until the positioning plate 28 reaches the specified position. The inserting plate 30 will press against the right-angled side of the positioning teeth 31 to limit it, so that the positioning plate 28 can only move in one direction towards the installation box 22. Movement, when the positioning plate 28 moves toward the installation box 22, the roller 29 at its end will follow the inclined surface of the pressing piece 26 and push the moving block 23 in the direction away from the outer frame 27 until the bottom of the moving block 23 contacts the speed reduction groove 14. Since the contact surfaces of the moving block 23 and the speed reduction groove 14 are made of frosted material, when the two are in contact, a large friction force will be generated. Under the action of the large friction force, the rotational resistance of the rotating shaft 8 will increase, and the corresponding swing speed of the cylinder 11 will also slow down, avoiding the cylinder 11 from swinging rapidly when the hull 1 shakes violently, causing resonance with the hull 1. The entire adaptive adjustment mechanism can automatically adjust the resistance according to the degree of shaking of the hull 1. When shaking slightly, it maintains a low resistance state to reduce unnecessary energy loss, ensure that the cylinder 11 can play its anti-rolling role normally, and automatically increase the resistance when encountering large turbulence or rapids causing violent shaking to achieve "on-demand adjustment". This adaptive characteristic enables the hull 1 to maintain a good anti-rolling effect in different water conditions, and always remain stable in a changing rescue environment, providing a reliable platform for rescue operations.

[0043] With reference to the above principle, when the cylinder 11 swings under the speed limit adjustment of the moving block 23 and other mechanisms, it can still work together with the unfolded slide 17 to reduce the shaking amplitude of the hull 1, so that the hull 1 can travel smoothly during the rescue process and ensure the rescue effect. When the hull 1 stops shaking violently, the operator can energize the electromagnet 35. When the electromagnet 35 is energized and becomes magnetic, the trigger magnet 36 rotates to the top of the electromagnet 35 along with the installation box 22 and other structures. At this time, under the repulsive magnetic force of the trigger magnet 36 and the electromagnet 35, the vertical plate 34 will drive the entire plug plate 30 to move in the direction away from the electromagnet 35, and then the bottom of the plug plate 30 no longer contacts the right-angled edge of the positioning tooth 31. At this time, there is no limit on the plug plate 30. Under the elastic force of the return spring 38, the entire positioning plate 28 will quickly move in the direction away from the outer frame 27, allowing the roller 2 9 is no longer in contact with the pressing member 26. At this time, without the pressure of the roller 29, the moving block 23 will also return to its original position under the elastic force of the pressing spring 25 and will no longer be in contact with the deceleration groove 14. At this time, the friction force generated by the contact between the moving block 23 and the deceleration groove 14 disappears, and the swing resistance of the rotating shaft 8 and the cylinder 11 disappears, which facilitates the cylinder 11 to swing normally without resistance when the hull 1 shakes slightly, thereby reducing the shaking amplitude of the entire hull 1. Through the arrangement of the moving block 23 and other mechanisms, when the hull 1 shakes violently, the rotating shaft 8 will swing greatly to drive the positioning plate 28 to hit the contact plate 21, and the cooperation of the plug plate 30 and the positioning tooth 31 will force the moving block 23 to contact with the deceleration groove 14, and use the friction resistance of the frosted surface to automatically increase the swing resistance of the cylinder 11 and reduce the swing speed. This mechanism can reduce the swing speed of the cylinder 11 when the hull 1 shakes violently, thereby avoiding resonance between the cylinder 11 and the hull 1.

[0044] It should be noted that when the hull 1 is traveling in a stable state, the hydraulic telescopic rod 4 is in a retracted state, and the baffle 7 will be located on the rotation path of the shaft 8. The baffle 7 blocks the limit protrusion 9, which can effectively prevent the rotation of the shaft 8. Therefore, when the hull 1 is running smoothly, the entire cylinder 11 does not shake. When the hull 1 shakes left and right, referring to the above principle, the hydraulic telescopic rod 4 will push the movable plate 6 downward, and the limit protrusion 9 will move downward synchronously. When the shaft 8 drives the limit protrusion 9 to rotate, the baffle 7 at this time is far away from the limit protrusion 9 and no longer blocks the limit protrusion 9. Therefore, the shaft 8 and the cylinder 11 can swing normally, maintain a low resistance state, and reduce unnecessary energy loss.

[0045] It should be noted that a valve is provided at the bottom of the cylinder 11 to discharge the iron sand inside the cylinder 11. When the hull 1 is sailing in normal waters, the iron sand in the cylinder 11 can be discharged in advance to reduce the weight of the entire hull 1.

[0046] It should be noted that, in the normal state, the two slides 17 are retracted at the tail of the hull 1 and are blocked by the entire hull 1. When the hull 1 is moving, the water flow does not directly rush towards the retracted slides 17. Therefore, when the slides 17 are in the retracted state, they will not affect the normal navigation of the hull 1.
