Description

Technical Field

[0001] The present invention relates to the technical field of airdrop boats, in particular to an airdrop boat anti-entanglement parachute abandonment device and a parachute abandonment method thereof. Background Art

[0002] During the airdrop process, there is a close connection between the airdrop equipment and the parachute, and no mistakes can occur, otherwise it will lead to damage to the airdrop equipment or even the failure of the airdrop mission.

[0003] Usually, when airdropping equipment on land, personnel can also be quickly airdropped to the corresponding area, and then the airdrop personnel will immediately separate the airdropped equipment from the parachute; but for airdrop speedboats on water, personnel cannot be airdropped simultaneously like on land; precisely because personnel cannot quickly reach the airdrop water area, they cannot implement the timely and safe separation of the parachute and the airdrop boat, which will bring many problems, such as: the problem of entanglement between the speedboat and the parachute, the problem of the speedboat capsizing due to the parachute falling into the water under the influence of wind and waves, etc., which not only affects the rapid commissioning of the speedboat, but may even cause the speedboat to fail to start normally. Summary of the Invention

[0004] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a rationally structured airdrop boat anti-entanglement parachute abandonment device and a parachute abandonment method, thereby achieving rapid and smooth unlocking and detachment of the parachute after the airdrop boat lands on the water, and effectively preventing the occurrence of entanglement problems between the parachute and components on the airdrop boat, which greatly helps to ensure that the airdrop boat can be put into use quickly and smoothly.

[0005] The technical solutions adopted in the present invention are as follows:

[0006] An anti-entanglement parachute abandonment device for an airdrop boat comprises a boat body, a support frame is mounted on the boat body, a space for accommodating control and communication equipment is provided below the support frame, and an elastic body is mounted on the top surface of the support frame; the support frame also comprises a suspension frame, the suspension frames are located above the elastic body and are connected to each other, and hanging ropes are installed between the four corners of the bottom surface of the suspension frame and the boat body; a rope locking mechanism is mounted on the top surface of the suspension frame, and the rope locking mechanism locks the end of the parachute rope below the parachute into connection or unlocks it.

[0007] As a further improvement of the above technical solution:

[0008] The structure of the suspension frame is as follows: it includes a horizontally arranged annular frame, a support plate is installed on the top surface of the annular frame, and the bottom surface of the support plate is fixedly connected to the top of the elastic body to form a floating structure; the bottom surface of the annular frame is provided with a plurality of lifting rings spaced along the circumferential direction, and a hanging rope is installed between each lifting ring and the hull.

[0009] An inverted U-shaped ring is fixedly provided on the hull, and the bottom end of the hanging rope is fixed on the U-shaped ring; the U-shaped ring is located outside the circumference of the support frame, and the hanging rope is arranged in an inclined structure extending outward from top to bottom.

[0010] The end of the parachute rope is arranged as a rope ring of an annular structure, and the rope ring is limitedly positioned on the pin of the rope locking mechanism, and the movement of the pin drives the rope ring to disengage and unlock.

[0011] The structure of the rope locking mechanism is as follows: it includes a support and a power mechanism installed at intervals on the top surface of the suspension frame, the output end of the power mechanism is set toward the support, and the output end of the power mechanism is installed with a pin via a flange structure; the power mechanism drives the pin to perform a linear movement along the axial direction, and the support includes two vertical plates arranged at intervals along the axial direction of the pin; the rope ring extends between the two vertical plates and is sleeved on the protruding pin.

[0012] Pin holes for pin insertion are concentrically provided on the two vertical plates of the support, and steps are provided on the pin along the circumference. The diameter of the pin on one side of the step is smaller than the diameter of the pin hole, so that the end of the pin is matched and inserted into the pin hole, and the diameter of the pin on the other side of the step is larger than the diameter of the pin hole. The step limits the insertion of the pin relative to the pin hole.

[0013] The support frame is a house-shaped frame structure, which provides protection for the operating and communication equipment inside; the end of the support frame is provided with an opening that is convenient for personnel to operate the operating and communication equipment.

[0014] The structure of the support frame is as follows: it includes horizontal tubes forming a horizontal rectangular frame structure, an annular tube with an annular structure is arranged parallel to the rectangular frame structure, and a diagonal bracing tube is installed between the end of the horizontal tube and the annular tube; a diagonal bracing tube is installed between the middle part of the three horizontal tubes in the rectangular frame structure and the annular tube, and an opening is formed at another horizontal tube for easy operation; a vertical tube is installed on the bottom surface of the end of the horizontal tube, and the bottom end of the vertical tube is fixed to the hull deck via a connecting block.

[0015] A method for abandoning a parachute by an airdrop craft airdrop anti-entanglement parachute abandonment device comprises the following steps:

[0016] After the boat lands on the water, the rope locking mechanism is activated to unlock the locking connection of the parachute rope below the parachute;

[0017] The airdrop boat began to sail, and the parachute moved away from the boat under the action of wind resistance, and was abandoned.

[0018] As a further improvement of the above technical solution:

[0019] The unlocking action of the locking rope mechanism is automatically controlled by the internal control system of the boat body, or is remotely controlled by a remote control device on the shore; the navigation of the airdrop boat is automatically controlled by the internal control system of the boat body after landing on the water, or is remotely controlled by a remote control device on the shore.

[0020] The beneficial effects of the present invention are as follows:

[0021] The present invention has a compact and reasonable structure and is easy to operate. The arrangement of the support frame on the hull effectively prevents the parachute from being entangled with the components on the airdrop boat after landing in the water, especially effectively avoids entanglement with the control and communication equipment, so that the airdrop boat can be started normally. The arrangement of the locking rope mechanism on the suspension frame above the support frame enables the parachute to be quickly and smoothly unlocked and detached after the airdrop boat lands in the water, further preventing the occurrence of entanglement between the parachute and the components on the airdrop boat, thereby greatly helping to ensure that the airdrop boat can be quickly and smoothly put into use.

[0022] The present invention also includes the following advantages:

[0023] The present invention adopts a unique method of connecting the hoisting and suspension but separating their functions, which not only ensures the parachute drop capability required of the airdrop boat, but also enables the airdrop boat to quickly and effectively separate the parachute from the boat body. In addition, by providing an anti-entanglement support frame, the problem of the parachute rope being entangled with the boat body equipment is fundamentally solved, ensuring the barrier-free start of the airdrop boat and clearing the obstacles for the ultimate goal of achieving the unity of man and boat.

[0024] The elastic body in the present invention can be a linear spring with constant thickness and density from top to bottom, a fixed elastic coefficient, and a certain tensile, compressive and lateral deflection capabilities to ensure that during the parachute abandonment process, the spring undergoes omnidirectional deformation that is beneficial to the parachute abandonment operation, thereby facilitating smooth parachute abandonment.

[0025] After the airdrop boat hits the water, the parachute will be blown out of the boat under the action of external wind (air resistance), and the timely unlocking of the locking rope mechanism will ensure the rapid separation of the parachute; in calm seas without external wind, the navigation of the airdrop boat will cause relative movement, and at the same time generate wind resistance to the parachute, prompting the smooth separation between the parachute and the boat; thereby effectively realizing and ensuring the smooth and rapid abandonment of the parachute after the airdrop boat hits the water, and being able to be put into use quickly.

[0043] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0044] like Figure 1 and Figure 3As shown, an airdrop boat airdrop anti-entanglement parachute abandonment device of this embodiment includes a hull 7, a support frame 6 is installed on the hull 7, a space for accommodating operating communication equipment 8 is enclosed below the support frame 6, and an elastomer 4 is installed on the top surface of the support frame 6; it also includes a suspension frame 3, the suspension frame 3 is located above the elastomer 4 and connected to each other, and hanging ropes 5 are installed between the four corners of the bottom surface of the suspension frame 3 and the hull 7; the rope locking mechanism 2 is installed on the top surface of the suspension frame 3, and the rope locking mechanism 2 locks the end of the parachute rope 11 below the parachute 1 to connect or unlock it.

[0045] By setting the support frame 6 on the hull 7, the parachute 1 is effectively prevented from being entangled with the components on the airdrop boat after landing on the water, especially the entanglement with the operating communication equipment 8 is effectively avoided, so that the airdrop boat can be started normally; by setting the locking rope mechanism 2 on the suspension frame 3 above the support frame 6, the airdrop boat and the parachute 1 are reliably connected during the airdrop process, and the parachute 1 is quickly and smoothly unlocked and detached after the airdrop boat lands on the water, further preventing the occurrence of entanglement problems between the parachute 1 and the components on the airdrop boat.

[0046] like Figure 2 As shown, the structure of the suspension frame 3 is as follows: it includes a horizontally arranged annular frame 32, the top surface of the annular frame 32 is installed with a support plate 31, the bottom surface of the support plate 31 is fixedly connected to the top of the elastic body 4 to form a floating structure; the bottom surface of the annular frame 32 is provided with a plurality of lifting rings 33 spaced along the circumferential direction, and a hanging rope 5 is installed between each lifting ring 33 and the hull 7.

[0047] like Figure 6 As shown, an inverted U-shaped ring 51 is fixedly provided on the hull 7, and the bottom end of the hanging rope 5 is fixed on the U-shaped ring 51; the U-shaped ring 51 is located outside the circumference of the support frame 6, and the hanging rope 5 is arranged in an inclined structure extending outward from top to bottom.

[0048] In this embodiment, the U-shaped ring 51 is fixed in the deck structure of the hull 7; combined with the layout of the facilities on the hull 7, four sets of U-shaped rings 51 can be set up, equipped with four hanging ropes 5 to install the suspension frame 3, so that the airdrop boat has the parachute hanging function.

[0049] In this embodiment, in the airdrop state, the elastic body 4 below the suspension frame 3 is usually in a natural state. When an external force is applied or the airdrop hits the water, the elastic body 4 will be deformed.

[0050] like Figure 4 As shown, the end of the parachute rope 11 is set as a rope ring 12 of an annular structure. The rope ring 12 is limited to the pin 21 of the rope locking mechanism 2. The pin 21 moves to drive the rope ring 12 to disengage and unlock.

[0051] In this embodiment, the end of the parachute cord 11 is provided with a special rope ring 12 structure in the shape of a circular hole, which facilitates the axial movement of the pin 21, thereby unlocking the lock between the parachute cord 11 and the rope locking mechanism 2.

[0052] like Figure 5 As shown, the structure of the rope locking mechanism 2 is as follows: it includes a support 22 and a power mechanism 24 installed at intervals on the top surface of the suspension frame 3, the output end of the power mechanism 24 is set toward the support 22, and the output end of the power mechanism 24 is installed with a pin 21 via a flange structure 23; the power mechanism 24 drives the pin 21 to perform a linear movement along the axial direction, and the support 22 includes two vertical plates arranged at intervals along the axial direction of the pin 21; the rope ring 12 extends between the two vertical plates and is fitted on the extended pin 21, thereby realizing the fitting limit of the rope ring 12 on the rope locking mechanism 2.

[0053] In this embodiment, the power mechanism 24 drives the pin 21 to perform linear motion. The power mechanism 24 can be a linear output mechanism such as an air cylinder, an oil cylinder, an electric push rod, etc.

[0054] Pin holes 221 for the pin column 21 to be inserted into are concentrically provided on the two vertical plates of the support 22. A step 211 is provided on the pin column 21 along the circumference. The diameter of the pin column 21 on one side of the step 211 is smaller than the diameter of the pin hole 221, so that the end of the pin column 21 is matched and inserted into the pin hole 221. The diameter of the pin column 21 on the other side of the step 211 is larger than the diameter of the pin hole 221. The step 211 forms a limit for the insertion of the pin column 21 relative to the pin hole 221.

[0055] The support frame 6 is a house-shaped frame structure, which provides protection for the control and communication equipment 8 inside to prevent the rope of the parachute 1 from falling into it and causing entanglement in the equipment, affecting the parachute abandonment operation; the end of the support frame 6 is provided with an opening for personnel to operate the control and communication equipment 8, so as to ensure that the personnel can manually operate the airdrop boat smoothly and conveniently after boarding the boat, thereby achieving the goal of integrating people and boats.

[0056] like Figure 7 and Figure 8 As shown, the structure of the support frame 6 is as follows: it includes horizontal tubes 63 forming a horizontal rectangular frame structure, an annular tube 61 of an annular structure is arranged parallel to the rectangular frame structure, and a diagonal bracing tube 62 is installed between the end of the horizontal tube 63 and the annular tube 61; a diagonal bracing tube 62 is installed between the middle of the three horizontal tubes 63 in the rectangular frame structure and the annular tube 61, and another horizontal tube 63 forms an opening for easy operation; a vertical tube 64 is installed on the bottom surface of the end of the horizontal tube 63, and the bottom end of the vertical tube 64 is fixed to the deck of the hull 7 via a connecting block 65.

[0057] In this embodiment, the diagonal support tube 62 can be directly fixedly welded to the upper annular tube 61 and the lower horizontal tube 63, or can be welded and connected via an intermediate plate according to actual needs.

[0058] In the present invention, a unique method of connecting the lifting and suspension but separating the functions is adopted, which not only ensures the parachute drop capability that the airdrop boat must have, but also enables the airdrop boat to have the ability of the parachute to quickly and effectively separate from the hull 7; in addition, by providing an anti-entanglement support frame 6, the problem of the parachute 1 rope 11 possibly being entangled with the hull equipment is fundamentally solved, ensuring the barrier-free start of the airdrop boat and clearing the obstacles for the ultimate goal of achieving the unity of man and boat.

[0059] The elastic body 4 in the present invention can be a linear spring with constant thickness and density from top to bottom, a fixed elastic coefficient, and certain tensile, compressive and lateral deflection capabilities to ensure that during the parachute abandonment process, the spring undergoes all-directional deformation that is beneficial to the parachute abandonment operation, thereby facilitating smooth parachute abandonment.

[0060] During the airdrop process, the weight of the hull 7 is transmitted sequentially via the U-shaped ring 51 to the lanyard 5, then to the hanger 3, then to the rope lock mechanism 2, then to the rope ring 12, the parachute 11, and finally to the parachute 1. During this entire load transfer process, the elastic body 4 is essentially unaffected by any forces, or in other words, the forces applied to the elastic body 4 do not cause permanent deformation. The primary function of the elastic body 4 in the present invention is neither to transmit the weight of the hull 7 nor to provide vibration damping for the airdrop parachute jettisoning mechanism, but rather to achieve safe parachute jettisoning.

[0061] For an airdrop boat, the key to achieving the parachute jettisoning function is how to make the parachute 1 as far away from or away from the boat body 7 as possible when the airdrop boat lands on the water, so as to avoid the unfavorable situation of the parachute rope 11 being entangled with the equipment.

[0062] Normally, there is a certain amount of wind on the surface of rivers, lakes, and seas. This wind is a favorable condition for parachutes 1 that utilize wind power (or air resistance). The stronger the wind, the easier it is to abandon the parachute. This is because the wind will blow the parachute 1 away from the hull 7, which means that the parachute lines will not be entangled in the equipment. At this time, the wind resistance of the parachute 1 and the gravity of the parachute after being immersed in water will drive the parachute lines 11 of the parachute 1 downward to one side of the suspension frame 3, causing the suspension frame 3 to tilt. This tilt effectively helps the parachute lines 11 to detach and complete the parachute abandonment.

[0063] Of course, if the weather is calm, the parachute 1 will land uniformly on the hull 7, making the aforementioned jettisoning method impossible. However, thanks to the use of an anti-entanglement support frame 6 specifically designed to prevent the parachute cord 11 from tangling with equipment on the hull 7, the jettisoning operation can still be accomplished using the airdrop boat jettisoning device. This involves remotely or automatically activating the airdrop boat and sailing it at high speed. The wind resistance created by the high-speed movement of the airdrop boat will cause the parachute 1 to move toward the stern of the hull 7 and fall into the water. This will also cause the suspension frame 3 to tilt, effectively facilitating successful jettisoning.

[0064] The method for abandoning a parachute by airdropping an anti-entanglement parachute device from an airdrop craft of this embodiment comprises the following steps:

[0065] After the hull 7 lands in the water, the rope locking mechanism 2 is activated to unlock the locking connection of the parachute rope 11 below the parachute 1. Specifically, the power mechanism 24 is activated to pull the pin 21 toward the power mechanism 24, so that the pin 21 is separated from the support 22. The rope ring 12 located between the two vertical plates of the support 22 is freed from the set restriction of the pin 21. The rope ring 12 is in a free state, and the hull 7 is unlocked from the parachute rope 11.

[0066] The airdrop boat starts to sail, and the parachute 1 moves away from the boat body 7 under the action of wind resistance, thus being abandoned.

[0067] After the airdrop boat hits the water, the parachute 1 will be blown out of the boat body 7 by the action of external wind (air resistance), and the timely unlocking of the locking rope mechanism 2 will ensure the rapid separation of the parachute 1; in the case of calm seas and no external wind, the navigation of the airdrop boat will cause relative movement, and at the same time generate wind resistance to the parachute 1, prompting the smooth separation between the parachute 1 and the boat body 7; thereby, effectively realizing and ensuring the smooth and rapid abandonment of the parachute after the airdrop boat hits the water, and being able to be put into use quickly.

[0068] Figure 9 Shown is a schematic diagram of the hull 7 in an airdrop state; Figure 10 The figure shows a schematic diagram of the hull 7 when it is in the water. Under the action of wind resistance, the parachute 1 will tilt laterally relative to the hull 7. Figure 11 The diagram shows the parachute 1 tilted to a certain degree until it falls into the water. At this time, the suspension frame 3 is subjected to the force of the parachute 1 and compresses the elastic body 4 to tilt. The falling of the parachute 1 further provides the parachute 1 with a force to separate from the hull 7.

[0069] The unlocking action of the locking rope mechanism 2 is automatically controlled by the internal control system of the hull 7, or is remotely controlled by a remote control device on the shore; the navigation of the airdrop boat is automatically controlled by the internal control system of the hull 7 after landing on the water, or is remotely controlled by a remote control device on the shore.

[0070] In this embodiment, the detection equipment provided on the hull 7 can be used to determine that the hull 7 has landed on the water when its falling speed suddenly drops or even reaches zero, or the landing state can be determined by the compression force of the elastic body 4, the inclination of the suspension frame 3, etc. Of course, other existing detection methods can also be used to determine that the hull 7 has reached the water state; then, the movement of the internal control program of the airdrop boat can be used to unlock the rope locking mechanism 2 and enable the airdrop boat to sail.

[0071] The present invention realizes rapid and smooth unlocking and detachment of the parachute after the airdrop boat lands on the water, effectively preventing the occurrence of entanglement problems between the parachute and components on the airdrop boat, thereby greatly helping to ensure that the airdrop boat can be put into use quickly and smoothly.

[0072] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
