Description

Technical Field

[0001] The invention relates to the technical field of boats and their peripheral supporting facilities, and in particular to a throwing anchoring device, a boat and a self-rescue method for a boat in distress. Background Art

[0002] A speedboat is a small, lightweight, maneuverable water vehicle that plays many important roles.

[0003] Assault boat rescue is an important emergency rescue work that uses assault boats to rescue and transfer trapped people when flood disasters occur. The driver should reasonably control the speed and direction of the assault boat according to the flow rate, flow direction, visibility and the position of the trapped people, and approach the trapped people in a stable and safe manner. During the approach, pay attention to avoid obstacles such as trees, telephone poles, building debris, floating objects, etc. Under normal circumstances, it is not advisable to go too fast to avoid difficulty in controlling the direction or capsizing due to the impact of water flow; but it should not be too slow to prevent being washed away by the flood or stagnating in whirlpools and undercurrents. In areas with faster flow, the speed should be kept within the range that can both resist the water flow and be flexible to control. When turning or avoiding obstacles, operate slowly and steadily to prevent the hull from capsizing due to excessive centrifugal force.

[0004] In rescue operations on turbulent rivers, it is inevitable to encounter dangerous areas such as whirlpools, undercurrents, and rapids, which may cause abnormal shaking of the speedboat or capsize accidents. Existing means are usually equipped with emergency tools such as ropes, but they are prone to failure when the speedboat is far away from the shore or there is no anchoring object on the shore. Especially under high flow conditions, it is difficult to effectively throw the rope to the shore to stabilize the ship, and it is very easy to fall off or fail during operation. In addition, in the scenario where the shore anchor point is missing, the traditional rope thrower lacks a ballistic correction mechanism (pitch angle adjustment range <±15°) and terminal guidance capabilities, and its effective throwing success rate drops sharply to less than 35% in water flows above level four. The existing emergency tools of the speedboat are difficult to adapt to harsh environments or sudden scenarios, and it is difficult to operate the speedboat stably.

[0005] In complex water environments such as sandy rivers and reservoirs in the north, there is serious sedimentation, unpredictable water levels, and shoals and reefs everywhere. In order to ensure the scientific nature of sediment dispatch, assault boats are often used to conduct field water and sediment observations and experiments. However, when encountering obstacles (irregular gullies, potholes, protrusions, and floating objects such as branches and weeds) in shallow waters, assault boats are very likely to run aground. Even if the ship is docked in deep water areas and operations are suspended, when the reservoir releases water or the river level drops, the soft mud is gradually exposed, and the bottom of the assault boat is often deeply sunken in the mud, increasing the risk of running aground. The water flow in sandy rivers and reservoirs is complex, and affected by factors such as sediment content and river channel morphology, whirlpools and undercurrents may form. These water currents will interfere with the normal driving trajectory of the assault boat, making it difficult for the driver to accurately control the boat, and it is easy to bring the boat to the shallow area and cause it to run aground. Once the assault boat becomes unstable or runs aground, the existing rescue methods are often stretched to the limit, which is not only inefficient, but may also pose a greater threat to personnel and equipment. Due to the lack of effective self-rescue or auxiliary remote throwing anchoring devices, the staff can only rely on rope dragging or manual lifting for rescue. However, the thick silt and the strong suction it produces make manual dragging difficult. It not only requires a lot of manpower and time, but also poses major risks to personnel safety (people are prone to getting stuck in the mud) and equipment safety (the bottom of the speedboat is prone to being scratched and leaking during the dragging process), which ultimately forced the field operation to be interrupted, seriously affecting the integrity and timeliness of data collection.

[0006] Therefore, how to solve the problems in the prior art of the difficulty of emergency rescue when the speedboat becomes unstable or runs aground in high-velocity water flow, and the poor safety of towing the speedboat for self-rescue, has become an urgent problem to be solved by technical personnel in this field.

[0052] In the event that the boat 36 is stranded or becomes unstable in turbulent water, when the throwing and anchoring device of the present invention is used for self-rescue, the work box 1 can be rotated first so that the launching hole of the work box 1 is facing the shore; the projection driver of the projection unit is used to transport the driving medium into the driving cavity, and under the driving action of the driving medium, the launching piston 18 is ejected from the outlet 38 of the launching tube 14, and the projection element 21 and the rope 13 move toward the shore with the launching piston 18. The projection element 21 projected onto the shore can be fixed on the shore, thereby achieving the purpose of stabilizing the boat 36; after the projection element 21 is fixed on the shore, the traction unit works, and the traction driver 7 drives the traction drum 12 to rotate, so that the rope 13 is wound around the traction drum 12, so as to achieve the purpose of dragging the boat 36 toward the shore. The casting and anchoring device of the present invention adopts a projection driver to drive the projection element 21, and the projection element 21 is cast to the shore to fix it on the shore, thereby avoiding the problems of unchanged operation of the manual casting rope 13 and difficulty in stabilizing the boat 36 in the prior art; at the same time, the casting and anchoring device of the present invention is provided with a traction unit, and the traction driver 7 is used to drive the traction drum 12 to rotate the winding rope 13 to achieve the towing of the boat 36. Compared with the manual towing or lifting rescue method in the prior art, the safety factor of the self-rescue operation of the boat 36 is greatly improved, and the safety of the boat 36 and the operator is improved.

[0053] In this specific embodiment, the base 29 is connected to a fixing ring 31, and the fixing ring 31 can be connected to the boat 36 by a chain (or iron chain, wire rope, etc.), so that the throwing anchor device of the present invention is fixed on the boat 36. The base 29 provides a stable support for the operation box 1. When the boat 36 is stranded or in distress, the operation box 1 ensures the working reliability of the projection unit and the traction unit, thereby effectively enhancing the distress self-rescue capability of the boat 36 and improving the convenience of the distress self-rescue operation of the boat 36. In other specific embodiments of the present invention, the base 29 can also be installed on the boat 36 in other ways, such as by binding or installing with a fixing element, to improve the installation convenience of the throwing anchor device of the present invention.

[0054] Among them, the work box 1 can rotate relative to the base 29, which is convenient for adjusting the direction of the launch hole of the work box 1 and ensuring the normal operation of the device. In practical applications, a rotary drive can be set to drive the rotation of the work box 1 to improve the movement accuracy of the work box 1. In order to improve the rotation reliability of the work box 1, a positioning mechanism is provided between the base 29 and the work box 1. The positioning mechanism includes a positioning block 30 and a positioning groove 6, and the positioning block 30 is rotatably connected to the positioning groove 6; the base 29 is provided with one of the positioning block 30 and the positioning groove 6, and the bottom of the work box 1 is provided with the positioning block 30 and the other one of the positioning groove 6.

On the basis of ensuring that the work box 1 can smoothly adjust its direction, the rotational dislocation of the work box 1 is avoided, thereby improving the movement stability of the work box 1.

[0055] In this specific embodiment, the positioning block 30 is a cylindrical structure, and the structure of the positioning groove 6 is adapted to the positioning block 30. For details, please refer to Figure 3 and Figure 4, positioning ribs 37 are arranged on the circumferential surface of the positioning block 30 and the side wall of the positioning groove 6. The positioning ribs 37 are arranged parallel to the axis of the positioning block 30 and the positioning groove 6. There are multiple groups of positioning ribs 37. The positioning ribs 37 are arranged circumferentially around the axis of the positioning block 30 and the positioning groove 6. Positioning recesses that match the positioning ribs 37 are formed between adjacent positioning ribs 37. The positioning ribs 37 can be engaged with the positioning recesses to form a gear-like structure. The positioning block 30 and the positioning groove 6 are engaged without affecting the relative rotation of the work box 1 and the base 29. After the work box 1 rotates to the right position relative to the base 29, the positioning ribs 37 are engaged with the positioning recesses, which can improve the structural stability of the work box 1 and the base 29 and prevent the rotation dislocation of the work box 1 from affecting the normal operation of the projection unit and the traction unit. At the same time, the positioning ribs 37 and the positioning recesses cooperate to monitor the rotation angle of the work box 1. When the positioning ribs 37 are evenly distributed around the axis of the positioning block 30 and the positioning groove 6, the work box 1 rotates a certain angle every time the positioning ribs 37 rotates through a positioning recess, which is convenient for the operator. It should also be noted that the cross-section of the positioning ribs 37 can be triangular, trapezoidal or arc-shaped, etc., to ensure that the positioning ribs 37 can be engaged with the positioning recesses, while preventing the positioning ribs 37 from affecting the normal rotation of the work box 1. It should be explained here that it is a common practice for those skilled in the art to reasonably set the sizes of the positioning ribs 37 and the positioning recesses to prevent the positioning ribs 37 from affecting the normal rotation of the work box 1, which will not be repeated here.

The box body and the box cover 4 are detachably connected, which is convenient for disassembly and maintenance of the parts in the work box 1. The box cover 4 is provided with a handle 3, which is convenient for holding and improves the convenience of operation of the work box 1. The launch hole is set on the side wall of the box body, and a launch cover 5 is set at the launch hole. The launch cover 5 is detachably connected to the box body. When the throwing and anchoring device of the present invention is not in use, the launch cover 5 is used to block the launch hole to prevent external environmental impurities from entering the work box 1 and the projection unit. In addition, the launch cover 5 and the box cover 4 are provided with sealing elements to ensure the sealing of the work box 1, provide effective protection for the device, and improve the working reliability of the throwing and anchoring device of the present invention. In addition, a control box 2 is also provided on the box body. The control box 2 has a built-in controller. The rotary drive, the projection unit and the traction unit are all connected to the controller for communication to control the working state of the throwing and anchoring device of the present invention. It should be explained here that the specific structure and working principle of the controller as well as the reasonable setting of power supply for the control and each unit are common means for those skilled in the art and will not be elaborated here.

[0057] In this specific embodiment, the projection driver is a compressed gas cylinder 33, see Figure 7The compressed gas cylinder 33 is connected to the driving cavity. The compressed gas cylinder 33 can transport driving gas into the driving cavity to drive the launching piston 18 to move. The driving medium can be compressed air or other compressed gas. The driving medium enters the driving cavity and pushes the launching piston 18 to move under the action of gas pressure to launch the launching piston 18. The launching piston 18 is used to drive the projection element 21 and the rope 13 to be thrown to the shore.

[0058] For the convenience of connection, the compressed gas cylinder 33 is connected to the drive cavity by means of the gas pipe 24, and the gas pipe 24 is connected to the launch tube 14 to realize the connection between the gas pipe 24 and the drive cavity. A control valve 35 is provided between the gas pipe 24 and the launch tube 14, and the control valve 35 is also connected to the controller for communication, so as to control the connection state between the gas pipe 24 and the drive cavity, and control the flow rate of the drive medium, so as to ensure the working reliability and controllability of the projection unit. It should also be noted here that the launch tube 14 of the present invention is provided with an exhaust hole 25 near the exit port 38, and after the launch piston 18 passes through the exhaust hole 25, the drive medium will leak out from the exhaust hole 25, so as to effectively prevent the safety hazard caused by excessive air pressure in the launch tube 14.

[0059] Specifically, the projection unit also includes a support frame 23 and a support plate 26. Figure 8 The support frame 23 is connected to the inner wall of the work box 1, the support plate 26 is arranged on the top of the support frame 23, the support plate 26 is inclined and is an arc-shaped plate, the compressed gas cylinder 33 is connected to the support plate 26, the launch tube 14 is connected to the compressed gas cylinder 33 by means of fixing screws 32, the launch tube 14 is also connected to the connecting seat 15, the launch tube 14 can be connected to the connecting seat 15 by means of a buckle 16, and the connecting seat 15 can be fixed on the inner wall of the work box 1, further ensuring the stability of the projection unit and providing stable support for the launch work. The support frame 23 and the support plate 26 cooperate to provide stable support for the launch tube 14 and the launch driver, and improve the structural stability of the projection unit.

[0060] In this specific embodiment, the inclination angle of the launch tube 14 is 45°. In practical applications, the boat 36 may have a certain angle between the tilted part and the horizontal plane. Reasonable setting of the angle between the launch tube 14 and the horizontal plane can meet various casting and anchoring conditions; for example, the angle between the tilted part at the front end of the assault boat and the horizontal direction is 15°, and the angle change range of the work box 1 when rotating to adjust the launch direction is 30° to 60° to meet the demand for the rope 13 to be launched farther. In a specific embodiment that can be realized by the present invention, the inclination angle of the launch tube 14 can be set to be adjustable, for example, the support plate 26 is movably connected to the support frame 23, and the angle of the support plate 26 is adjusted to achieve the purpose of adjusting the inclination angle of the launch tube 14, meet different specific working conditions, and improve the flexibility and adaptability of the device.

[0061] It should also be emphasized that the inner wall of the launch tube 14 is provided with rifling 22 so that the projection element 21 can rotate when it is ejected with the launch piston 18. The projection element 21 is rotatably connected to the launch piston 18. The projection element 21 is a rotating body structure, and the radial cross-sectional area of ​​the projection element 21 gradually decreases along the axis of the projection element 21 in the direction away from the launch piston 18. The end of the projection element 21 away from the launch piston 18 has a tip. The throwing anchor device of the present invention has rifling 22 on the inner wall of the launch tube 14. When the projection element 21 is ejected with the launch piston 18, the projection element 21 contacts the rifling 22 and rotates forward along the path of the rifling 22. The rotation gives the projection element 21 additional kinetic energy to increase the initial velocity of the projection element 21, increase the range of the projection element 21, enhance the throwing effect of the projection unit, and improve the adaptability of the throwing anchor device of the present invention. In order to extend the service life of the projection unit, the launch tube 14 and the launch piston 18 can be made of high temperature and high pressure resistant materials. It should be explained here that it is a common practice for those skilled in the art to reasonably set the specific shape of the rifling 22 according to different casting and launching conditions, as well as the shape specifications of the projection element 21, and will not be elaborated here.

[0062] In order to prevent the launching piston 18 from rotating with the projection element 21, the launching piston 18 is connected to the projection element 21 by a connecting shaft 19. The connecting shaft 19 is rotatably connected to the projection element 21 and a bearing 20 is arranged therebetween. Under the premise of not affecting the rotation of the projection element 21, the connection reliability between the launching piston 18 and the projection element 21 is ensured. Furthermore, the launching piston 18 is only ejected with the projection element 21 without rotating, thereby avoiding the energy loss of the rope 13 caused by rotation and winding, which is beneficial to increase the shooting range.

[0063] In this specific embodiment, the projection element 21 is a cone-shaped structure, and the outer peripheral surface of the projection element 21 is a curved surface, so as to reduce the resistance of the projection element 21 and help to further increase the range of the projection element 21.

[0064] More specifically, the rope 13 is connected to the launch piston 18 by a rope clip 17, and a suitable type of rope clip 17 can be selected according to the specifications of the rope 13, such as a U-shaped rope clip 17. In this specific embodiment, a rope hole 34 for placing the rope 13 is provided on the launch tube 14 to prevent the rope 13 from affecting the launch piston 18 and the launch of the projection element 21. In actual applications, the type and specifications of the rope 13 can be selected and adjusted according to actual working conditions to meet different traction requirements.

[0065] Furthermore, the traction unit further includes a driving shaft 9, a driving gear 8, a driven gear 10 and a traction shaft 11, please refer to Figure 5 and Figure 6The output end of the traction driver 7 is connected to the drive shaft 9, the drive gear 8 is connected to the drive shaft 9, the drive gear 8 is meshed with the driven gear 10, the driven gear 10 is connected to the traction shaft 11, the traction shaft 11 is rotatably arranged in the working box 1, and the traction shaft 11 is connected to the traction drum 12. In this specific embodiment, the traction unit adopts a gear transmission mechanism to drive the traction drum 12 to rotate, and the transmission is stable and efficient, so that the rope 13 is wound on the traction drum 12, so as to realize the use of the rope 13 to pull the boat 36, realize the traction of the boat 36, avoid the problem of poor safety of manual traction, and improve the traction work efficiency. In other specific embodiments that can be realized by the present invention, the traction unit can also use other transmission mechanisms to drive the traction drum 12 to rotate, such as a belt transmission mechanism, a sprocket transmission mechanism, etc., while realizing smooth power transmission, improving the flexibility and adaptability of the device. Among them, the traction driver 7 can select a variable frequency motor.

[0066] In this specific embodiment, the number of traction drums 12 is two groups, and correspondingly, the number of ropes 13 is two groups. When the traction unit is working, the two groups of traction drums 12 and ropes 13 can simultaneously drag the boat 36, and it is convenient to control the dragging direction of the boat 36, ensuring that the boat 36 moves smoothly toward the shore, further improving the working reliability of the traction unit. In other specific embodiments that can be realized by the present invention, anti-skid patterns are provided on the outer peripheral surface of the traction drum 12 to increase the friction between the traction drum 12 and the rope 13, effectively preventing the rope 13 from slipping on the surface of the traction drum 12, and further improving the working reliability of the traction unit.

[0067] Furthermore, the anchoring device of the present invention further comprises a shore-based fixing unit, see Fig. 9 The shore-based fixing unit includes a spiral pile 27 and a pile buckle 28. The spiral pile 27 includes a main rod and a spiral blade. One end of the main rod is connected to a pile head. The cross-sectional area of ​​the pile head is larger than that of the main rod. The other end of the main rod is an inverted cone structure. The spiral blade is spirally wound on the outer circumference of the main rod and is arranged close to the inverted cone structure. The pile buckle 28 is connected to the spiral pile 27, and the pile buckle 28 can be connected to the end of the rope 13 launched with the projection element 21. The spiral pile 27 can be quickly screwed into the shore ground by the spiral blade, and the rope 13 is connected to the pile buckle 28, further providing a stable anchoring foundation for the traction of the boat 36. The traction unit retracts the rope 13 to drag the boat 36. The spiral blade adopts a variable pitch and wide width design. This design enables the spiral pile 27 to penetrate different geological layers more easily when screwed into the ground, providing a stronger anchoring force than traditional piles.

[0068] In this specific embodiment, the surface of the spiral pile 27 and the pile buckle 28 is subjected to a special hot-dip galvanizing treatment, which effectively enhances the corrosion resistance of the shore-based fixing unit. The spiral pile 27 and the pile buckle 28 are an integrated structure. The pile buckle 28 is designed as an ergonomic handle type and is made with the spiral pile 27 by an integrated casting process, which ensures the strength and stability of the structure. The handle-type pile buckle 28 is provided with a serrated anti-skid pattern inside. When the rope 13 is fixed in the pile buckle 28, the serrated anti-skid pattern can effectively prevent the rope 13 from sliding. In actual use, the operator can easily hold the handle-type pile buckle 28 and quickly screw the spiral pile 27 into the ground to complete the shore fixing work, avoiding the risk of relative displacement or loose connection between the bayonet structure and the supporting component during the dragging process, and ensuring that the fixation of the rope 13 is more stable and reliable.

[0069] The throwing and anchoring device of the present invention realizes convenient adjustment of the launching direction by combining the working box 1 with the base 29, and effectively solves the problem of insufficient flexibility of the self-rescue operation of the boat 36 in the prior art when facing complex situations such as siltation, volatile water levels, and numerous shoals and reefs. Compared with the prior art, the present invention can better adapt to on-site conditions such as instability and grounding. Through the multi-physical field coupling control technology, the projection accuracy of the projection unit is improved to 3.2 times that of the traditional rope thrower, which significantly improves the self-rescue ability and operational safety of the boat 36 in complex water environments. At the same time, the present invention reduces the risk rate of direct contact of personnel by 92% by designing the projection unit and the traction unit in a linkage manner, and installing them on the boat 36, and configuring an independent direct-insertion shore-based fixed unit on the shore, thereby effectively overcoming the many disadvantages of the traditional manual dragging method in the process of boat 36 grounding rescue, such as low efficiency, time-consuming and labor-intensive, and difficulty in ensuring the safety of rescue personnel. In addition, the throwing and anchoring device of the present invention can be activated immediately in different time periods and complex environments, significantly shortening the time from rescue preparation to implementation, thereby ensuring that the boat 36 can escape from the dangerous state in the shortest time. The existing shore traction and recovery mechanism is generally large in size, which causes great inconvenience during transportation and is difficult to be quickly deployed to the required location. In addition, the deployment of the prior art device must be completed in advance, lacking the ability to flexibly respond to emergencies. The present invention optimizes the device structure to give the device excellent portability and installability, while significantly reducing the volume and weight of the device. This not only solves the inconvenience of transportation and the limitation of having to be deployed in advance of the existing shore traction and recovery mechanism, but also significantly improves the adaptability and response speed of the device, so that it can better adapt to the use requirements in complex environments. In addition, the present invention ensures the stability and reliability of each component through optimization and innovation in the projection unit, traction unit and shore-based fixed unit, solves the problem that the traditional rescue equipment has poor reliability and is prone to failures that affect the rescue process, and is particularly suitable for rapids with a flow rate of more than 4m / s and tidal flats with a silt thickness of more than 0.8m, greatly improving the adaptability of the throwing and anchoring device of the present invention.

[0070] Embodiment 2

[0071] This embodiment provides a casting anchoring device. In this specific implementation, the projection driver is an elastic element. In the initial state, the elastic element is in a compressed state under the action of an external force. The elastic element is connected to the driving cavity. When the external force applied to the elastic element is removed, the elastic element restores its deformation and enters the driving cavity and pushes the launching piston 18 to move, so as to launch the launching piston 18. The launching piston 18 is used to drive the projection element 21 and the rope 13 to be cast to the shore. In this specific implementation, the driving medium is the force of the elastic element to restore its deformation. The elastic element can be made of a spring or other elastic material. A limiting element can be used to apply a force to the elastic element so that the elastic element is in a compressed state in the initial state. The limiting element is separated from the elastic element. The external force applied by the limiting element to the elastic element can be removed, so that the elastic element restores its deformation and pushes the launching piston 18 to move.

[0072] The other structures of the casting anchoring device of this embodiment are the same as those of the first embodiment and will not be described again here.

[0073] Embodiment 3

[0074] This embodiment discloses a boat 36, including the throwing anchor device of the first embodiment or the second embodiment. When facing complex situations such as silt accumulation, erratic water level, numerous shoals and reefs, the boat 36 uses the throwing anchor device to perform self-rescue operations, thereby improving the self-rescue capability and operation safety of the boat 36 in complex water environments.

[0075] The boat 36 of the present invention is mainly a small watercraft. The boat 36 of this embodiment includes but is not limited to the following types: a speedboat, a yacht, and a sports boat.

[0076] Embodiment 4

[0077] This embodiment discloses a method for self-rescue of a boat in distress, using the throwing anchor device of the first embodiment or the second embodiment, including the following steps:

[0078] Rotate the operation box 1 so that the launch hole faces the shore;

[0079] The projection unit works, the projection driver delivers the driving medium into the driving cavity, the launching piston 18 moves along the launching tube 14 under the action of the driving medium, the launching piston 18 is ejected from the ejection port 38, the projection element 21 and the rope 13 move toward the shore along with the launching piston 18, and the projection element 21 is fixed to the shore to stabilize the boat 36;

[0080] The traction unit works, and the traction drive 7 drives the traction drum 12 to rotate, so that the rope 13 is wound around the traction drum 12, so as to achieve traction of the boat 36 toward the shore.

[0081] When the boat 36 runs aground, the following operations can be followed for self-rescue: first, the operator uses the controller to trigger the projection unit, and the compressed gas cylinder 33 pushes the launch piston 18 with a pressure of 15 MPa, so that the projection element 21 with a unique cone head is launched in the launch tube 14 with asymmetric variable pitch rifling 22 based on aerodynamics inside. The projection element 21 is connected to the launch piston 18 through a high-precision connecting shaft 19, and the bearing 20 between the connecting shaft 19 and the projection element 21 enables the projection element 21 to rotate independently. The initial launch velocity reaches 40m / s, and the rope 13 is accurately projected to 100 meters from the shore. Then the rescuer quickly wraps the rope 13 around the spiral pile 27 and buckles it into the pile buckle 28. Finally, the operator operates the controller to start the traction unit. The variable frequency motor of the traction unit initially drives the traction drum 12 with a special texture treatment on the surface to rotate. The rotation of the traction drum 12 causes the rope 13 to wrap around the traction drum 12, so as to achieve the purpose of dragging the boat 36 out of the stranded area. When the boat 36 is in distress, the throwing anchoring device of the present invention is used for self-rescue, which greatly improves the safety factor of the self-rescue operation of the boat 36 compared to the rescue method of manual dragging or lifting in the prior art.

[0082] In actual application, when the speedboat is stranded or unstable, the first task is to perform integrity testing on the throwing anchor device of the present invention to ensure that the pressure-bearing sealing, torque output capacity and braking performance of the traction unit of the device are maintained in an ideal state. After verifying the device status through the touch-screen human-machine interface of the controller, the operation box 1 is activated to perform a ±180° continuous rotation positioning operation according to the shore terrain characteristics, water flow direction and the specific location of the stranding.

[0083] According to the topographic features of the shore, the direction of the water flow and the specific location where the assault boat is stranded, the controller controls the operation box 1 to rotate and position. Prevent angle deviation during the launch process. After the angle adjustment is completed, the operation box 1 is locked by the controller to prevent misoperation. When launching, the button on the control box 2 that controls the compressed gas cylinder 33 is activated, so that the high-pressure gas pushes the launch piston 18 forward in the launch tube 14. The projection element 21 in the launch tube 14 is launched under the push of the launch piston 18, wherein the projection element 21 realizes independent rotation under the action of the connecting shaft 19 and the bearing 20, and the launch piston 18 is ejected together with the projection element 21 but does not rotate. The rope 13 located in the two grooves of the launch tube 14 is ejected together with the projection element 21. In this specific embodiment, the angle between the launch tube 14 and the base 29 is set to 45°, and six rifling grooves 22 are provided inside the launch tube 14 to ensure that the front projection element 21 obtains sufficient kinetic energy, thereby improving the initial velocity and the launch stability, and accurately projecting the rope 13 to the shore. One end of the rope 13 is fixedly connected to the projection unit. During the launching process, the rope 13 located in the two grooves of the launching tube 14 is launched together with the projection element 21 to ensure a smooth launching process.

[0084] The dynamic model of the ejected projection element 21 and the rope 13 is established and solved as follows:

[0085] For the ejected projection element 21, the main energy loss in the air comes from air resistance. The expression of air resistance is:

[0086]

[0087] Among them, F c ——air resistance; C——air resistance coefficient; ρ——air density; S——windward area of ​​the object; V——relative speed between the object and the air;

[0088] In the design, since the speed of the projection element 21 is much less than Mach 2.5, aerodynamic heating will not occur. In dry air, the air density ρ is about 1.293 kg / m 3 The projection element 21 is a cone structure with a bottom diameter of about 5 cm, so the frontal area of ​​its tip is equal to its bottom area, about 19.63 cm 2 According to the wind tunnel experiment, a cone model is placed in a wind tunnel, a stable airflow with a known flow rate is generated through the wind tunnel, and a high-precision force measuring device (such as a strain balance) is installed on the model to directly measure the air resistance of the cone. It can be seen that for a cone with a tip angle θ≤30°, the drag coefficient when the tip faces the wind is about 0.2 to 0.5. In order to ensure maximum energy loss, the drag coefficient is taken as 0.5 this time.

[0089] In the process of launching the projection element 21 to the highest point, in addition to the loss of air resistance, there is also a loss of gravitational potential energy. The expression of gravity is:

[0090] G = mg (1-2)

[0091] Among them, G is the gravity; m is the mass of the object; g is the acceleration due to gravity; the mass of the object and the traction rope is about 5kg (the rope weighs 4.5kg and the cone weighs 0.5kg), and the acceleration due to gravity is 9.8N / kg.

[0092] By using the principle of independence of motion, the oblique projection motion of the projection element 21 can be decomposed into horizontal motion and vertical motion, namely:

[0093] v=v x +v y (1-3)

[0094] Let k = CρS, then the air resistance can also be decomposed into horizontal and vertical resistance, that is:

[0095]

[0096] Considering the vertical movement of the projection element 21, assuming that the upward movement direction of the projection element 21 is a square, according to Newton's second law, the differential equations of motion satisfied when rising and falling are:

[0097]

[0098] The differential equation of motion in the horizontal direction is:

[0099]

[0100] Assuming that the initial velocity of the projection element 21 is v0, and the angle between the velocity direction and the horizontal direction is θ, the initial velocities in the horizontal direction and the vertical direction are respectively:

[0101] v x0 =v 0 cosθ

[0102] v y0 =v 0 sinθ (1-7)

[0103] Due to dv y / dt=v y dv / dy, after substituting it into (1-5), the separated variable v y and y, and then compare v on both sides of the equation y Integrate y and y separately, and we can get:

[0104]

[0105] Solving the integral equation can give the maximum rising height H of the ball.

[0106] When descending:

[0107]

[0108] Substituting the required maximum height H into the above formula, we can obtain the final vertical velocity v yt .

[0109] Separate the speed and time in equation (1-5) and integrate both sides to obtain:

[0110]

[0111] Where t 1 is the rising time of the cone, t 2 is the total time of the movement. yt Substituting into (1-10), solving the two fractions together, we can solve for the total motion time t 2 .

[0112]

[0113] The total movement time t 2 Substituting into the above formula, we can obtain the final horizontal velocity v xt .

[0114] DV x / dt=v x After substituting dv / dx into (1-6), the separation variable v x and x, and then compare v on both sides of the equation x Integrating x and x separately, we can get the following formula:

[0115]

[0116] Horizontal terminal velocity v x After substituting into the above formula, the horizontal displacement expression can be obtained:

[0117]

[0118] Therefore, given the mass of the projection element 21 and the air resistance coefficient, the initial velocity v of the projection element 21 can be calculated by only knowing the maximum horizontal range that the projection element 21 can reach after launching and its angle θ with the horizontal direction. 0 .

[0119] This design is for a fixed device at a target of 100m, so we can set x = 100 in formula (1-13), and substitute θ = 30° and θ = 45° into formula (1-13) to obtain:

[0120] When θ=30°, v 0 =44.47m / s; when θ=45°, v 0 =39.98m / s; when θ=30°, v 0 =52.53m / s;

[0121] Therefore, in the angle that is convenient to control, when θ=45°, the initial launch speed of the projection element 21 is the smallest, that is, when θ=45°, the initial energy given to the projection element 21 is the smallest. Therefore, in order to stably project the projection element 21 at 100m, the initial speed of the projection element 21 at the launch position needs to be about 40m / s. Using the energy calculation formula, it can be obtained that the energy of the projection element 21 is about 4000J at this time. Therefore, when using the high-pressure gas generating device for energy storage, an energy of 4000J is required.

[0122] Furthermore, the core of the projection unit lies in the storage and controllable release of high-pressure gas, wherein the commonly used high-pressure gas cylinder has a rated pressure of 15MPa, and its gas energy storage far exceeds the required energy requirements. According to the calculation of the gas state equation and the work done by expansion, 15MPa of high-pressure gas can release enough energy during the expansion process to meet the demand of 4000J. The present invention can prove that it is completely feasible for the compressed gas cylinder 33 to generate 4000J of energy by reasonably designing the gas release mechanism (setting a control valve 35, and in other specific embodiments that can be realized by the present invention, a nozzle can also be set) and ensuring that the energy conversion efficiency reaches the expected level. In addition, combined with the actual operating data of the commonly used gas generating device, the actual energy output of the gas expansion is highly consistent with the theoretical calculated value, which further verifies the reliability and feasibility of the device.

[0123] After the launch is completed, the rescue personnel on the shore must quickly and firmly anchor the spiral pile 27 of the shore-based fixed unit to the shore ground to ensure the stability of the fixing device. Then, the launched rope 13 is firmly tied to the pile buckle 28 of the shore-based fixed unit to achieve mechanical interlocking to ensure the reliability of the connection and avoid falling off during the towing process.

[0124] On the assault boat, the operator operates the controller to start reverse recovery. The driving gear 8 is driven to rotate by the traction driver 7, and the driving gear 8 is meshed with the driven gear 10 for transmission, so that the driven gear 10 drives the traction shaft 11 to rotate. The traction drum 12 fixed on the traction shaft 11 rotates accordingly and begins to retract the rope 13. One end of the rope 13 is fixed on the traction drum 12, and gradually winds during the rotation of the traction drum 12. The other end is connected to the projection unit and has been fixed on the ground pile buckle 28 on the shore. By winding up the rope 13, the assault boat is towed away from the stranded area. During the towing process, if the assault boat is offset, tilted, or the tension of the rope 13 is abnormal, the rotation speed of the traction driver 7 can be controlled by the controller according to the actual situation to adapt to different water currents and stranded conditions, to ensure that the towing process is smooth and safe, and finally complete self-rescue. For example, when the speedboat deviates to one side, the rope-collecting speed of the traction drum 12 on that side is reduced and the contraction speed of the traction drum 12 on the other side is increased accordingly, so that the speedboat maintains a straight line drag.

[0125] When the assault boat successfully escapes from the stranding, stop the traction drive 7, loosen the connection between the rope 13 and the shore-based fixed unit, and then operate the controller to slowly retract the rope 13 into the traction drum 12, and clean the mud, debris, etc. on the surface of the rope 13. Recover the spiral pile 27 of the shore-based fixed unit, clean the soil on the surface, and check whether the spiral pile 27 is damaged. If damaged, repair or replace it in time. Rotate the operation box 1 back to the initial position, turn off the power of the operation box 1, clean the debris inside the operation box 1, and check whether the connection of each component is loose. Check the pressure of the compressed gas cylinder 33 and replenish the gas, check whether the control valve 35 and the gas pipe 24 of the compressed gas cylinder 33 are leaking, and repair them in time if there is any. Clean and lubricate the rifling 22 of the launch tube 14, use the cleaning tool to remove the dirt and impurities in the rifling 22, and then apply lubricant to ensure the smooth and stable launch of the subsequent projection element 21. Check the electrical equipment such as the motor and controller to ensure that there are no moisture, short circuit and other faults.

[0126] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
