Technical Field

[0001] This application relates to the field of marine equipment technology, and in particular to a marine net deployment device and a ship. Background Technology

[0002] Currently, unmanned aerial vehicle (UAV) technology is widely used in my country's ship pilotage technology field. Through its real-time information collection capabilities, UAVs conduct targeted observation and analysis of ship route information, ensuring that pilots can receive effective information to control the ship and issue various control commands, thereby carrying out pilotage work steadily and efficiently.

[0003] In related technologies, ships are affected by various natural factors such as wind, waves and tides when sailing at sea, causing dynamic changes such as swaying and tilting of the hull. This makes it difficult for drones to adapt during landing, increasing the difficulty and risk of landing drones on ships. Utility Model Content

[0004] This application provides a shipboard net deployment device and a ship, which can solve the technical problem of the high difficulty of landing drones on ships.

[0005] In a first aspect, embodiments of this application provide a device for deploying a ship's netting, comprising:

[0006] Base;

[0007] A support arm is movably connected to the base. The support arm is provided with a plurality of hanging ears arranged at intervals along the extension direction of the support arm. The hanging ears are used to connect with the netting.

[0008] A driving component is disposed on the base and connected to the support arm. The driving component is used to drive the support arm to move relative to the base so that the support arm switches between an extended position and a retracted position.

[0009] When the support arm is in the extended position, it forms an angle with the base to unfold the netting; when the support arm is in the retracted position, it closes with the base to retract the netting.

[0010] In some embodiments, the base includes a base body and a first pivot seat disposed on the base body, the support arm is rotatably connected to the first pivot seat, and the driving member is used to drive the support arm to rotate between the unfolded position and the retracted position.

[0011] In some embodiments, the base further includes a limiting seat, which is spaced apart from the first pivot seat on the base body, and the limiting seat is provided with a limiting groove. When the support arm is in the retracted position, the support arm is at least partially located in the limiting groove.

[0012] In some embodiments, the base further includes a support block disposed on the base body, and the first pivot seat is disposed on the support block.

[0013] In some embodiments, the base further includes a second pivot seat, which is disposed on the base body and spaced apart from the first pivot seat. The first end of the drive member is rotatably connected to the second pivot seat, and the second end of the drive member is rotatably connected to the support arm. The first end and the second end of the drive member are opposite ends.

[0014] In some embodiments, the base body is provided with a plurality of mounting positions, which are arranged sequentially at intervals along the direction close to the first pivot seat, and the second pivot seat is selectively mounted on one of the plurality of mounting positions.

[0015] In some embodiments, a sleeve is fitted on the peripheral side of the support arm, and the second end of the drive member is rotatably connected to the sleeve.

[0016] In some embodiments, the socket is provided with a plurality of hinge positions, which are arranged sequentially at intervals along the extension direction of the support arm, and the second end of the drive member is selectively rotatably connected to one of the plurality of hinge positions.

[0017] In some embodiments, the peripheral sidewall of the support arm is provided with a movable groove, the movable groove extends along the extension direction of the support arm, and a plurality of the hanging ears are movably disposed in the movable groove.

[0018] Secondly, embodiments of this application provide a vessel, which includes a hull and a vessel net deployment device as described above, wherein the base is fixedly mounted on the hull.

[0019] The shipboard net deployment device and the ship based on the embodiments of this application have at least the following beneficial effects:

[0020] By fixing the base to the ship and movably connecting one end of the support arm to the base, and placing a drive unit between the base and the support arm, the drive unit can drive the support arm to move towards or away from the base. The support arm is equipped with multiple lugs that can be connected to the netting. When the drone needs to land on the ship, the drive unit can move the support arm to the unfolded position, at which point the netting can be unfolded vertically. The netting is elastic, and the drone can directly collide with the netting and be captured. After being captured by the netting, the drone can land safely on the ship. After landing, the drive unit can move the support arm to the retracted position to retract the netting, reducing the space occupied on the ship's deck. Therefore, even when the ship is rocking irregularly, the drone can land on the ship easily. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] Please see Figure 1 and Figure 2 This application provides a shipboard net deployment device 100, which includes a base 10, a support arm 20, and a drive unit 30. The base 10 can be fixed to the hull of the ship. The support arm 20 can be movably connected to the base 10, so that the support arm 20 can move relative to the base 10. The support arm 20 can be provided with a plurality of hanging ears 201, which can be arranged sequentially at intervals along the extension direction of the support arm 20. The hanging ears 201 can be connected to the net 40. The drive unit 30 can be disposed on the base 10 and connected to the support arm 20. The drive unit 30 can be used to drive the support arm 20 to move relative to the base 10, so that the support arm 20 switches between an deployed position and a retracted position.

[0030] When the support arm 20 is in the extended position, it can be set at an angle with the base 10, thereby unfolding the barrier net 40. The drone can directly collide with the barrier net 40 and be captured by it. When the support arm 20 is in the retracted position, it can be closed with the base 10, thereby retracting the barrier net 40.

[0031] Optionally, at least two bases 10 are provided on the hull, with the two bases 10 arranged opposite each other, and each base 10 is movably connected to a support arm 20. The opposite sides of the net 40 are respectively connected to the lugs 201 on the two support arms 20. When the drone needs to land on the ship, the two drive units 30 simultaneously drive the two support arms 20 to move relative to the bases 10. Both support arms 20 move to the unfolded position, at which time the net 40 can be unfolded vertically. The net 40 is elastic, and the drone can directly collide with the net 40 and be captured by the net 40. After being captured by the net 40, the drone can land safely on the ship. After landing, the drive unit 30 can drive the support arms 20 to move to the retracted position to retract the net 40, which can reduce the space occupied on the ship deck. Therefore, even when the ship is swaying irregularly, the drone can land on the ship very easily.

[0032] Please see Figure 1 and Figure 2 In some embodiments, the base 10 may include a base body 1 and a first pivot seat 2 disposed on the base body 1, the support arm 20 may be rotatably connected to the first pivot seat 2, and the drive member 30 is used to drive the support arm 20 to rotate between the unfolded position and the retracted position.

[0033] Optionally, the base body 1 is a long plate structure, the base body 1 can be fixed on the hull, the first pivot seat 2 can be set at one end of the base body 1, one end of the support arm 20 can be rotatably connected to the first pivot seat 2, the driving member 30 can drive the support arm 20 to rotate away from the base body 1 to the unfolded position, and the driving member 30 can also drive the support arm 20 to rotate towards the base body 1 to the folded position.

[0034] When the support arm 20 is in the extended position, the support arm 20 can be set at an angle with the base body 1, so that the barrier net 40 is tilted relative to the horizontal plane, which makes it convenient for the drone to crash into the barrier net 40 from above. When the support arm 20 is in the retracted position, the other end of the support arm 20 can contact the other end of the base body 1, or in other words, the other end of the support arm 20 and the other end of the base body 1 are located at the same place, thereby closing the support arm 20 and the base body 1, thus retracting the barrier net 40 and reducing the space occupied on the deck.

[0035] Please see Figure 1 and Figure 2 In some embodiments, the base 10 may also include a limiting seat 3, which is disposed on the base body 1 at a distance from the first rotating shaft seat 2, and the limiting seat 3 is provided with a limiting groove 31. When the support arm 20 is in the retracted position, the support arm 20 is at least partially located in the limiting groove 31.

[0036] Optionally, the limiting seat 3 and the first rotating shaft seat 2 can be spaced apart along the extension direction of the base body 1. Alternatively, the limiting seat 3 and the first rotating shaft seat 2 can be respectively located at opposite ends of the base body 1. When the support arm 20 is in the retracted position, the end of the support arm 20 away from the first rotating shaft seat 2 can contact the limiting seat 3, and the support arm 20 can be located in the limiting groove 31. The limiting groove 31 can prevent the support arm 20 from swaying left and right.

[0037] Please see Figure 1 and Figure 2 In some embodiments, the base 10 may also include a support block 4, which may be disposed on the base body 1, and the first pivot seat 2 may be disposed on the support block 4.

[0038] Optionally, the support block 4 and the limiting seat 3 can be respectively disposed at opposite ends of the base body 1. The support block 4 can raise the setting height of the first rotating shaft seat 2, so that when the support arm 20 is in the retracted position, there can be a certain gap between the support arm 20 and the base body 1 to form a receiving space. The driving member 30 can be disposed in the receiving space, which can prevent the driving member 30 from interfering with the support arm 20, thereby enabling the support arm 20 and the base body 1 to be better retracted together, further reducing the space occupied.

[0039] Please see Figures 1 to 3 In some embodiments, the base 10 may also include a second pivot seat 5, which may be disposed on the base body 1 and spaced apart from the first pivot seat 2. The first end of the drive member 30 may be rotatably connected to the second pivot seat 5, and the second end of the drive member 30 may be rotatably connected to the support arm 20. The first end and the second end of the drive member 30 are opposite ends.

[0040] Optionally, the second pivot seat 5 and the first pivot seat 2 can be spaced apart along the extension direction of the base body 1. One end of the support arm 20 is rotatably connected to the first pivot seat 2, the first end of the drive member 30 is rotatably connected to the second pivot seat 5, and the second end of the drive member 30 is rotatably connected to the peripheral wall of the support arm 20. When the support arm 20 is in the unfolded position, the support arm 20, the base body 1, and the drive member 30 can form a triangular structure, so that the support arm 20 can more stably support the barrier net 40 and prevent the barrier net 40 from being knocked down when the drone collides with it.

[0041] It should be noted that the driving component 30 has a structure similar to a telescopic rod. One end of the driving component 30 can extend or retract relative to the other end, thereby driving the support arm 20 to rotate relative to the base body 1.

[0042] Please see Figure 1 and Figure 3 In some embodiments, the base body 1 may be provided with a plurality of mounting positions 11, and the plurality of mounting positions 11 may be arranged sequentially at intervals along the direction close to the first pivot seat 2, and the second pivot seat 5 may be selectively mounted on one of the plurality of mounting positions 11.

[0043] Optionally, multiple mounting positions 11 can be arranged in a row at intervals along the extension direction of the base body 1, so that the distance between the multiple mounting positions 11 and the first rotating shaft seat 2 is not equal. By installing the second rotating shaft seat 5 on different mounting positions 11, the amplitude of the rotation of the support arm 20 driven by the drive member 30 can be adjusted. More specifically, the longer the distance between the mounting position 11 and the first rotating shaft seat 2, the longer the extension stroke required for the drive member 30 to drive the support arm 20 to rotate by the same angle.

[0044] For ease of description, the mounting position 11 farther from the first pivot seat 2 is defined as the first mounting position, and the mounting position 11 closer to the first pivot seat 2 is defined as the second mounting position. When the second pivot seat 5 is mounted in the first mounting position, if the driving member 30 needs to drive the support arm 20 to rotate by a preset angle, the driving member 30 needs to extend or retract by a first preset distance. When the second pivot seat 5 is mounted in the second mounting position, if the driving member 30 needs to drive the support arm 20 to rotate by a preset angle, the driving member 30 needs to extend or retract by a second preset distance, and the first preset distance is greater than the second preset distance. Therefore, by mounting the second pivot seat 5 in different mounting positions 11, the range of rotation of the support arm 20 driven by the driving member 30 can be adjusted, thereby enabling more precise adjustment of the unfolding angle of the support arm 20.

[0045] Please see Figure 1 and Figure 4 In some embodiments, the peripheral side of the support arm 20 can be fitted with a sleeve 202, and the second end of the drive member 30 can be rotatably connected to the sleeve 202.

[0046] Optionally, the socket 202 may include a cylindrical part and a connecting part, the connecting part being connected to the peripheral side wall of the cylindrical part, the cylindrical part being sleeved on the peripheral side of the support arm 20, and the second end of the drive member 30 being rotatably connected to the connecting part, so that the drive member 30 can drive the support arm 20 to rotate relative to the base body 1, thereby making it easy to drive the support arm 20 to switch between the extended position and the retracted position.

[0047] Please see Figure 4 In some embodiments, the socket 202 may be provided with a plurality of hinge positions 2021, which may be arranged sequentially at intervals along the extension direction of the support arm 20, and the second end of the drive member 30 may be selectively rotatably connected to one of the plurality of hinge positions 2021.

[0048] Optionally, the connecting part is provided with multiple hinge positions 2021. By rotating the second end of the driving member 30 to different hinge positions 2021, the range of rotation of the support arm 20 driven by the driving member 30 can also be adjusted. More specifically, the longer the distance between the hinge position 2021 and the first rotating shaft seat 2, the longer the extension stroke required for the driving member 30 to drive the support arm 20 to rotate by the same angle. The principle is the same as that by installing the second rotating shaft seat 5 on different mounting positions 11, the range of rotation of the support arm 20 driven by the driving member 30 can be adjusted, which will not be elaborated here.

[0049] Please see Figure 1 In some embodiments, the peripheral sidewall of the support arm 20 may be provided with a movable groove 203, which may extend along the extension direction of the support arm 20, and a plurality of hanging ears 201 may be movably disposed in the movable groove 203.

[0050] Optionally, the lugs 201 can move along the movable groove 203, thereby adjusting the gap between two adjacent lugs 201. When the support arm 20 is in the extended position, the two adjacent lugs 201 can be moved away from each other by a calibrated distance along the movable groove 203, so that the barrier net 40 can be extended better, increasing the area of ​​the barrier net 40, making it easier for the drone to collide with the barrier net 40. When the support arm 20 is in the retracted position, the two adjacent lugs 201 can be brought closer together along the movable groove 203, so that the barrier net 40 can be retracted better, further reducing the space occupied by the barrier net 40.

[0051] This application embodiment also provides a ship, including a hull and a ship net deployment device 100 as described above, wherein the base 10 is fixedly disposed on the hull.

[0052] The beneficial effects of the vessel in this application and the vessel net deployment device 100 in this application will not be described in detail here.
