Description

Technical Field

[0001] This utility model relates to the field of rope technology, specifically to a rope assembly for parachute-launched objects. Background Technology

[0002] Deploying buoys via parachute is a common technique used in marine scientific research, meteorological observation, and marine environmental monitoring. This method utilizes the deceleration and stabilization effect of the parachute to safely and accurately deploy buoys and other marine observation equipment to designated sea areas to obtain marine environmental data.

[0003] Existing methods involve using a drone to carry a parachute and buoy to a designated sea area, then releasing the drone and deploying the parachute to gently drop the buoy to the desired location. The parachute is connected to the buoy by a rope, but the rope cannot be quickly disconnected during deployment. This results in the parachute becoming entangled in the buoy upon impact, affecting its usability. Therefore, we propose a rope assembly for parachute-launched objects. Utility Model Content

[0004] The purpose of this invention is to provide a rope assembly for parachute-launched objects, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rope assembly for parachute-thrown objects, comprising a housing, a hole on the upper side of one side wall of the housing, a first movable column passing through the top of the housing, a first rope fixedly connected to the top of the first movable column, fixing rings fixedly fitted on the upper and lower sides of the outer wall of the first movable column, a first spring fitted on the outer wall of the first movable column, one end of the first spring being fixedly connected to the corresponding fixing ring, and the other end of the first spring being fixedly connected to the top of the inner cavity of the housing;

[0006] The inner cavity of the housing is provided with a limiting plate, and a limiting groove is formed on the top of the limiting plate. An elastic pushing component is installed in the limiting groove, and the elastic pushing component is connected to the tail end of the first movable column.

[0007] One end of the limiting plate is engaged with a limiting plate, the tail end of the limiting plate is fixedly connected to a movable block, the tail end of the movable block is fixedly connected to a second movable column, and the tail end of the second movable column is fixedly connected to a second rope.

[0008] By adopting the above technical solution, when the buoy is deployed, the first and second ropes are pulled, the first spring is stretched, and the limiting plate is pulled to the lower side of the hole. Then, when the buoy contacts the sea surface, the tension of the second rope decreases, so the first spring will drive the next fixing ring to rise, thereby lifting the first movable column, which in turn can drive the limiting plate to rise. When the limiting plate rises to the hole, the elastic pushing component can push the limiting plate to move laterally, so that the limiting plate extends out of the hole and disengages from the limiting plate. At this time, the second movable column drives the movable block to descend, thereby disengaging from the shell, thus achieving rapid separation.

[0009] In a preferred embodiment of this utility model, the elastic pushing assembly includes a fixed rod, a limiting slider, and a second spring. The fixed rod is fixedly installed in the inner cavity of the limiting groove, the limiting slider is slidably mounted on the fixed rod, the second spring is mounted on the outer wall of the fixed rod, and the two ends of the second spring are fixedly connected to the side wall of the limiting slider and the inner wall of the limiting groove, respectively. The top of the limiting slider is fixedly connected to the tail end of the first movable column.

[0010] By adopting the above technical solution, when the limiting plate is located in the inner cavity of the housing, the second spring is in a compressed state. When the movable column moves upward, the limiting plate moves upward accordingly. When the limiting plate moves to the hole, the second spring will push the limiting plate to move laterally relative to the limiting slider to extend and retract the hole, thereby enabling the limiting plate to disengage from the clamping plate.

[0011] In a preferred embodiment of this utility model, grooves are provided on both sides of the two side walls of the movable block, and rollers are rotatably installed in the upper and lower cavities of the grooves.

[0012] By adopting the above technical solution, after the limiting plate is released, the movable block moves downward under the action of gravity. At this time, the rolling of the roller can reduce friction, which helps to avoid the movable block being obstructed when sliding out of the shell, and further improves the separation effect.

[0013] In a preferred embodiment of this utility model, a lead ring is fixedly fitted on the lower side of the outer wall of the second movable column.

[0014] By adopting the above technical solution, the lead ring can be added to increase the weight of the second movable column, thereby increasing the downward force when the movable block slides out of the shell, and thus further improving the separation effect.

[0015] In a preferred embodiment of this utility model, a positioning pin is inserted through the outer wall of the housing, a slot is provided on the movable block, the positioning pin is inserted into the slot, and a pull rope is fixed to the outer wall of the positioning pin.

[0016] By adopting the above technical solution, the position of the movable block can be initially positioned using the positioning pin, thereby keeping the device in a limited state at the initial stage.

[0017] In a preferred embodiment of this utility model, the length of the hole is greater than the width of the limiting plate.

[0018] By adopting the above technical solution, the limiting plate can extend out of the hole without obstruction, which helps to avoid spatial obstacles.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The present application provides a rope assembly for parachute-launched objects. When a buoy is slowly descending to the sea surface via a second rope, the buoyancy reduces the tension of the second rope, causing the limiting plate, limiting latch, and movable block to rise under the return action of the first spring. When the limiting plate moves to the hole, the second spring pushes the limiting plate to move laterally, causing the limiting plate to disengage from the limiting latch. This allows the movable block and limiting latch to slide out of the shell, achieving rapid separation. As the parachute continues to descend, it is blown away by the wind, thus helping to prevent the parachute and telescopic mechanism from entangled with the buoy.

[0021] After the limiting plate and the limiting card plate separate, the movable block will move downward under its own weight, thereby detaching from the housing. The outer wall of the second movable column is provided with a lead ring, which makes the second movable column fall. At the same time, during the downward sliding process of the movable block, the rolling action of the roller can greatly reduce the frictional resistance when the movable block slides down from the housing, thereby further improving the effect of rapid separation.

[0030] Please see Figure 1-4 The present invention provides a technical solution: a rope assembly for parachute throwing objects, including a housing 1, wherein a hole 11 is provided on the upper side of one side wall of the housing 1;

[0031] The top of the housing 1 has a first movable column 12 through it. The top of the first movable column 12 is fixedly connected to a first rope 13. The upper and lower sides of the outer wall of the first movable column 12 are fixedly fitted with fixing rings 18. The outer wall of the first movable column 12 is fitted with a first spring 19. One end of the first spring 19 is fixedly connected to the corresponding fixing ring 18, and the other end of the first spring 19 is fixedly connected to the top of the inner cavity of the housing 1.

[0032] The inner cavity of the housing 1 is provided with a limiting plate 22, and a limiting groove 25 is formed on the top of the limiting plate 22. An elastic pushing component is installed in the limiting groove 25, and the elastic pushing component is connected to the tail end of the first movable column 12.

[0033] One end of the limiting plate 22 is engaged with the limiting plate 21, the tail end of the limiting plate 21 is fixedly connected to the movable block 2, the tail end of the movable block 2 is fixedly connected to the second movable column 14, and the tail end of the second movable column 14 is fixedly connected to the second rope 15.

[0034] Specifically, when the buoy is deployed, the first rope 13 and the second rope 15 are pulled. At this time, the first spring 19 is pulled up, and the limiting plate 22 is pulled to the lower side of the hole 11. Then, when the buoy contacts the sea surface, the tension of the second rope 15 decreases, so the first spring 19 will drive the next fixing ring 18 to rise, thereby raising the first movable column 12, which in turn can drive the limiting plate 22 to rise. When the limiting plate 22 is raised to the hole 11, the elastic pushing component can push the limiting plate 22 to move laterally, so that the limiting plate 22 extends out of the hole 11 and disengages from the limiting plate 21. At this time, the second movable column 14 drives the movable block 2 to descend, thereby disengaging from the shell 1, thus achieving rapid separation.

[0035] Furthermore, a positioning pin 16 is inserted through the outer wall of the housing 1, and a slot 23 is provided on the movable block 2. The positioning pin 16 is inserted into the slot 23, and a pull rope 17 is fixed to the outer wall of the positioning pin 16.

[0036] Specifically, the positioning pin 16 can be used to initially position the movable block 2, thereby keeping the device in a limited state at the beginning stage.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; the elastic pushing assembly includes a fixed rod 26, a limiting slider 27, and a second spring 28. The fixed rod 26 is fixedly installed in the inner cavity of the limiting slide groove 25. The limiting slider 27 is slidably fitted on the fixed rod 26. The second spring 28 is fitted on the outer wall of the fixed rod 26. The two ends of the second spring 28 are fixedly connected to the side wall of the limiting slider 27 and the inner wall of the limiting slide groove 25, respectively. The top of the limiting slider 27 is fixedly connected to the tail end of the first movable column 12.

[0038] Specifically, when the limiting plate 22 is located in the inner cavity of the housing 1, the second spring 28 is in a compressed state. When the movable column 12 moves upward, the limiting plate 22 moves upward accordingly. When the limiting plate 22 moves to the hole 11, the second spring 28 will push the limiting plate 22 to move laterally relative to the limiting slider 27 to extend and retract the hole 11, thereby enabling the limiting plate 22 to disengage from the clamping plate 21.

[0039] It should be noted that the length of the hole 11 is greater than the width of the limiting plate 22, so that the limiting plate 22 can extend out of the hole 11 without obstruction, which helps to avoid spatial obstacles.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown; grooves are provided on both sides of the two side walls of the movable block 2, and rollers 24 are rotatably installed in the upper and lower cavities of the grooves;

[0041] After the limiting plate 21 is released, the movable block 2 moves downward under the action of gravity. At this time, the rolling of the roller 24 can reduce friction, which helps to prevent the movable block 2 from being obstructed when sliding out of the housing 1, and further improves the separation effect.

[0042] Furthermore, a lead ring is fixedly fitted on the lower side of the outer wall of the second movable column 14. The lead ring allows the second movable column 14 to be weighted, thereby increasing the downward force when the movable block 2 slides out of the housing 1, and further improving the separation effect.

[0043] The implementation principle of the rope assembly for parachute-launched objects in this application is as follows: In use, the first rope 13 is connected to the parachute, and the second rope 15 is connected to the buoy. Then, a drone is used to lift the parachute and buoy to a designated location. During the lifting process, the pull rope on the positioning pin 16 is connected by a connecting rope, which is also connected to the drone. Thus, during the slow descent using the parachute, the drone pulls out the positioning pin 16 as it flies away. At this time, under the gravity of the buoy, the movable block 2 remains in a downward state, preventing the limiting plate 22 from moving upward. When slowly descending to the water surface, the buoy contacts the water surface, and the buoyancy reduces the tension of the second rope 15 on the movable block 2. At this time, the first spring 19 pulls back... Under the action of force, the first movable column 12 moves upward, which in turn drives the limiting plate 22 to move upward. At this time, the movable block 2 and the limiting plate 21 will move upward as well. When it moves to the hole 11, the second spring 28 will push the limiting plate 22 to move laterally relative to the limiting slider 27 to extend the hole 11, so that the limiting plate 22 can be separated from the plate 21. After the limiting plate 21 is released, the movable block 2 moves downward under the action of gravity. At this time, the roller 24 can reduce friction by rolling, so that the movable block 2 can quickly slide out of the shell 1, thereby achieving rapid separation. After separation, the parachute is still descending. At this time, the wind on the sea surface can blow the separated parachute away, which helps to avoid the parachute from getting tangled with the buoy.
