Description

Technical Field

[0001] The present invention belongs to the technical field of marine monitoring equipment, and particularly relates to an air-dropping device and a deployment method for marine observation and detection equipment. Background Art

[0002] Marine observation and detection equipment is an important device in the fields of marine environment monitoring, meteorological observation, waterway marking, etc. The efficiency and safety of its deployment operation directly affect the quality of marine data acquisition. The traditional deployment method of marine observation and detection equipment mainly relies on being carried by boats. However, the ocean area is vast and the sea conditions are complex and changeable. The sailing speed of boats is slow, and it often takes a lot of time to complete a marine observation and detection equipment deployment task. At the same time, a large amount of manpower is required for operation and maintenance, resulting in low overall efficiency.

[0003] With the development of unmanned aerial vehicles (UAVs), more and more marine observation and detection equipment is deployed by air-dropping with UAVs. UAVs have the advantages of fast flight speed and long flight range, and can efficiently and safely complete the deployment tasks of a large number of marine observation and detection equipment, and can successfully complete the deployment work without being interfered by the outside world. But in the existing technology, in the device for air-dropping marine observation and detection equipment, the fixing and releasing mechanism of the marine observation and detection equipment is relatively complex, and the working reliability is low. The marine observation and detection equipment is prone to jamming when released, which may cause the marine observation and detection equipment to miss the best release position, resulting in the marine observation and detection equipment falling into the water at a relatively far distance from the designated position, affecting the acquisition effect of the marine observation and detection equipment. And the marine observation and detection equipment is in a free-fall state in the air during air-dropping, resulting in a relatively fast speed when it falls into the sea, and a large pressure will be generated at the moment of contact with the sea water, which is easy to damage the marine observation and detection equipment, thus affecting the normal use of the marine observation and detection equipment and the accuracy of data acquisition.

[0004] Therefore, how to design an air-dropping device for marine observation and detection equipment with a simple structure and / or an air-dropping method that can make the marine observation and detection equipment land smoothly on the sea surface is of great significance for the deployment of marine observation and detection equipment on the sea. Summary of the Invention

[0005] In view of the deficiencies in the related art, the present invention provides an air-dropping device and a deployment method for marine observation and detection equipment to simplify the structure of the air-dropping device for marine observation and detection equipment and increase the accuracy of air-dropping of marine observation and detection equipment.

[0006] The present invention provides an air-dropping device for marine observation and detection equipment, which is installed on a UAV; the air-dropping device for marine observation and detection equipment includes: A base, which is detachably connected to the abdomen of the UAV; a fixing frame is connected below the base; The clamping ring is used to clamp ocean observation and detection equipment; the clamping ring includes a clamping member, and the upper end of the clamping member is rotatably connected to a fixed frame; there are two clamping members, and the two clamping members are arranged opposite to each other in the circumferential direction and are rotatably connected to each other; when the lower ends of the two clamping members rotate towards each other, the ocean observation and detection equipment is clamped; when the lower ends of the two clamping members rotate away from each other, the ocean observation and detection equipment is released. The telescopic frame can be telescoped along the width direction of the telescopic frame to adjust the length dimension of the telescopic frame; the two ends in the length direction of the telescopic frame are arranged corresponding to the two clamping members one by one; the telescopic frame is connected to the upper end of the clamping member; when the telescopic frame contracts, the lower ends of the two clamping members rotate towards each other; when the telescopic frame extends, the lower ends of the two clamping members rotate away from each other. The motor is installed on the base and is used to drive the telescopic frame to expand and contract.

[0007] In this technical solution, by making the base detachably connected to the abdomen of the unmanned aerial vehicle, the aerial delivery device of the ocean observation and detection equipment can be installed on or disassembled from the unmanned aerial vehicle according to actual needs; by designing the clamping ring to include two clamping members, the two clamping members are arranged opposite to each other in the circumferential direction and are rotatably connected to each other, so as to realize the clamping and release of the ocean observation and detection equipment, and use the motor to drive the telescopic frame to expand and contract to control the rotation of the clamping members. This not only enables the clamping ring to reliably fix the ocean observation and detection equipment, increases the reliability of the clamping ring's work, but also realizes the automatic control of the clamping ring, avoids complex manual operations, reduces the risk of operation errors, improves the work reliability. At the same time, the overall structure is simple, easy to implement and maintain, and can accurately transport the ocean observation and detection equipment to a specified position above by means of the unmanned aerial vehicle and release it, meeting the requirements of the deployment of the ocean observation and detection equipment in ocean monitoring.

[0008] In some embodiments, a receiving cavity is provided at one end of the ocean observation and detection equipment, and the receiving cavity is used to store the parachute; the parachute is connected to the end of the ocean observation and detection equipment where the receiving cavity is provided, and the parachute is also connected to the base through a rope; when the ocean observation and detection equipment is released, the parachute is pulled out of the receiving cavity under the pulling force of the rope.

[0009] In this technical solution, by installing a parachute on the ocean observation and detection equipment, the ocean observation and detection equipment can slowly fall under the action of the parachute, reducing the falling speed of the ocean observation and detection equipment, and avoiding the large impact on the water surface caused by the too fast falling speed of the ocean observation and detection equipment, resulting in damage to the ocean observation and detection equipment; by providing a receiving cavity, the receiving cavity is used to store the parachute, and the parachute is connected to the base through a rope, so that when the ocean observation and detection equipment is released, under the pulling force of the rope and the gravity of the ocean observation and detection equipment, the parachute can be pulled out of the receiving cavity, thus releasing the restraint of the receiving cavity on the parachute.

[0010] In some of these embodiments, a connecting shaft is connected to the rotating shaft of the motor; the connecting shaft is arranged through the fixing frame so that the fixing frame supports the rotation of the connecting shaft; first and second collars are respectively provided at both ends of the telescopic frame in the width direction, the first and second collars are respectively sleeved on the outer periphery of the connecting shaft, the first collar is slidably connected to the connecting shaft, and the second collar is threadedly connected to the connecting shaft.

[0011] In some of these embodiments, the telescopic frame includes four connecting bars, and the four connecting bars are rotatably connected to form a quadrilateral structure. The connecting bars are arranged in the horizontal direction, and two adjacent connecting bars are connected to each other through a rotating member; the first and second collars are correspondingly connected to two rotating members in the width direction of the telescopic frame; two clamping members are correspondingly connected to two rotating members in the length direction of the telescopic frame.

[0012] In some of these embodiments, a first connecting portion and a second connecting portion are provided at the upper end of the clamping member. The first connecting portion is located on the side where the clamping member and another clamping member are close to each other, and the first connecting portion is rotatably connected to the fixing frame and another clamping member; the second connecting portion is located obliquely above the first connecting portion and is located on the side where the two clamping members are away from each other, and the second connecting portion is rotatably connected to the telescopic frame.

[0013] In some of these embodiments, the two clamping members are rotatably connected to each other through a first rotating shaft; a fixing portion is provided at the bottom of the fixing frame, the first rotating shaft is arranged through the fixing portion, and the clamping member and the fixing portion are rotatably connected to each other through the first rotating shaft.

[0014] In some of these embodiments, a sliding groove is provided on the fixing portion, and the sliding groove is arranged in the vertical direction; the first rotating shaft can slide up and down along the sliding groove; when the first rotating shaft slides downward, the telescopic frame extends; when the first rotating shaft slides upward, the telescopic frame contracts.

[0015] In some of these embodiments, a controller is further included. The controller is connected to the motor and is configured to: control the rotation of the motor so that the telescopic frame contracts or extends, thereby clamping or releasing the ocean observation detection equipment by the clamping ring; When the first rotating shaft slides to the bottom of the sliding groove, control the motor to stop running.

[0016] In addition, the present invention also provides a method for deploying an ocean observation detection equipment. The ocean observation detection equipment is deployed on the sea surface by using the ocean observation detection equipment airdropping device as described above; the method for deploying the ocean observation detection equipment includes the following steps: Install a parachute at one end of the ocean observation detection equipment where the accommodation cavity is provided, and store the parachute in the accommodation cavity; at the same time, connect the parachute to the base through a rope; The motor drives the telescopic frame to extend, causing the lower ends of the two clamping members to rotate away from each other, making the holding ring in an open state. The ocean observation detection equipment is horizontally placed inside the holding ring, and then the motor drives the telescopic frame to contract, causing the holding ring to clamp the ocean observation detection equipment; After the unmanned aerial vehicle flies to a position above the designated location according to the preset route, the motor drives the telescopic frame to extend, causing the lower ends of the two clamping members to rotate away from each other to release the ocean observation detection equipment. The parachute is pulled out of the accommodation cavity under the action of the tension of the rope and the gravity of the ocean observation detection equipment; the ocean observation detection equipment falls to the designated location under the action of its own gravity and the parachute.

[0017] In some of the embodiments, after the ocean observation detection equipment is released, the end of the ocean observation detection equipment without the accommodation cavity falls first, and the end of the ocean observation detection equipment with the accommodation cavity is delayed in falling under the action of the tension of the rope, so that the ocean observation detection equipment finally falls in a vertical posture.

[0018] Based on the above technical solutions, in the embodiment of the present invention, the aerial delivery device for ocean observation detection equipment drives the telescopic frame to expand and contract through a motor to control the holding ring to clamp or release the ocean observation detection equipment. Thus, the ocean observation detection equipment can be carried by the unmanned aerial vehicle to a position above the designated location, and then the holding ring releases the ocean observation detection equipment, so as to airdrop the ocean observation detection equipment to the designated location; the overall structure is simple and the load capacity of the holding ring is strong, and the aerial delivery of larger-sized ocean observation detection equipment can be realized.

[0021] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0023] The terms "first", "second", "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", "third" may explicitly or implicitly include one or more of such features.

[0024] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] As shown Figures 1 - 6 in a schematic embodiment of the aerial delivery device of the marine observation and detection equipment of the present invention, the aerial delivery device of the marine observation and detection equipment is installed on a drone; the aerial delivery device of the marine observation and detection equipment includes a base 1, a clamping ring 4, a telescopic frame 3, and a motor 2; the base 1 is detachably connected to the abdomen of the drone; a fixing frame 11 is connected below the base 1; the clamping ring 4 is used to clamp the marine observation and detection equipment 5; the clamping ring 4 includes a clamping member 41, and the upper end of the clamping member 41 is rotatably connected to the fixing frame 11; the clamping member 41 is provided with two, and the two clamping members 41 are arranged opposite to each other along the circumferential direction and are rotatably connected to each other; when the lower ends of the two clamping members 41 rotate towards each other, the marine observation and detection equipment 5 is clamped; when the lower ends of the two clamping members 41 rotate away from each other, the marine observation and detection equipment 5 is released; the telescopic frame 3 can be telescoped along the width direction of the telescopic frame 3 to adjust the length dimension of the telescopic frame 3, so as to drive the clamping member 41 to rotate; the two ends in the length direction of the telescopic frame 3 are arranged in one-to-one correspondence with the two clamping members 41; the telescopic frame 3 is connected to the upper end of the clamping member 41; when the telescopic frame 3 contracts, the lower ends of the two clamping members 41 rotate towards each other; when the telescopic frame 3 extends, the lower ends of the two clamping members 41 rotate away from each other; the motor 2 is installed on the base 1 and is used to drive the telescopic frame 3 to telescope.

[0026] It should be noted that when the telescopic frame 3 extends, the length of the telescopic frame 3 decreases and the width of the telescopic frame 3 increases; when the telescopic frame 3 contracts, the length of the telescopic frame 3 increases and the width of the telescopic frame 3 decreases.

[0027] For the convenience of description, in this embodiment, the rotation of the lower ends of the two clamping members 41 towards each other is referred to as the closing of the clamping ring 4, and the rotation of the lower ends of the two clamping members 41 away from each other is referred to as the opening of the clamping ring 4.

[0028] The above-mentioned air-dropping device for ocean observation detection equipment controls the opening or closing of the clamping ring 4 by telescoping the telescopic frame 3, so as to realize the clamping and release of the ocean observation detection equipment 5; and a motor 2 is provided to control the telescoping of the telescopic frame 3 to realize the automatic opening and closing of the clamping ring 4. The overall structure of the air-dropping device for ocean observation detection equipment is simple, the control method of the clamping ring 4 is simple, and the working reliability is high.

[0029] The operation steps of the above-mentioned air-dropping device for ocean observation detection equipment for air-dropping the ocean observation detection equipment 5 are as follows: The motor 2 drives the telescopic frame 3 to extend, so that the lower ends of the two clamping members 41 rotate away from each other, so that the clamping ring 4 is opened. The ocean observation detection equipment 5 is placed in the clamping ring 4, and then the motor 2 drives the telescopic frame 3 to contract, so that the clamping ring 4 clamps the ocean observation detection equipment 5; when the unmanned aerial vehicle flies to a position above the designated position according to the preset route, the motor 2 drives the telescopic frame 3 to extend, so that the lower ends of the two clamping members 41 rotate away from each other, so that the clamping ring 4 is opened to release the ocean observation detection equipment 5, so that the ocean observation detection equipment 5 falls to the designated position under the action of gravity.

[0030] It should be noted that the motor 2 is a motor with a locking function. When the clamping ring 4 clamps the ocean observation detection equipment 5, the motor 2 is locked so that the clamping ring 4 is always in a state of clamping the ocean observation detection equipment 5, thereby ensuring the fixing effect of the ocean observation detection equipment 5. The motor with a locking function belongs to the prior art in this field and will not be elaborated here.

[0031] As Figures 2 - 4 shown, the two clamping members 41 are rotatably connected to each other through a first rotating shaft 401, and the clamping member 41 is rotatably connected to the telescopic frame 3 through a second rotating shaft 402; the first rotating shaft 401 and the second rotating shaft 402 are arranged in the same direction, so that the clamping member 41 can rotate relative to the telescopic frame 3 and the other clamping member 41 at the same time, so as to realize the rotation of the clamping member 41 controlled by the telescopic frame 3 telescoping.

[0032] The upper end of the clamping member 41 is provided with a first connecting portion and a second connecting portion. The first connecting portion is rotationally connected to the fixing bracket 11 and another clamping member 41 through a first rotating shaft 401, and the second connecting portion is rotationally connected to the telescopic bracket 3 through a second rotating shaft 402. The first connecting portion is located on the side where the clamping member 41 and another clamping member 41 are close to each other. The second connecting portion is located obliquely above the first connecting portion and on the side where the two clamping members 41 are away from each other.

[0033] As Figure 2 shown, the bottom of the fixing bracket 11 is provided with a fixing portion 13, and the first rotating shaft 401 passes through the fixing portion 13 so that the clamping member 41 is rotationally connected to the fixing portion 13 through the first rotating shaft 401. The mutual rotation between the two clamping members 41 and the mutual rotation between the clamping member 41 and the base 1 are realized through the same first rotating shaft 401, which can not only increase the reliability and stability of the movement of the clamping member 41, but also simplify the overall structure.

[0034] As Figure 3 and Figure 4 shown, the fixing portion 13 is provided with a sliding groove 14, and the sliding groove 14 is arranged in the vertical direction. The first rotating shaft 401 can slide up and down along the sliding groove 14. When the telescopic bracket 3 extends, the first rotating shaft 401 slides downward. When the telescopic bracket 3 contracts, the first rotating shaft 401 slides upward.

[0035] It should be noted that the sliding groove 14 also increases the rotation angle of the clamping member 41, so that the holding ring 4 can clamp the ocean observation detection equipment 5 with a larger diameter.

[0036] It should also be noted that the top and bottom of the sliding groove 14 respectively limit the sliding of the first rotating shaft 401. When the first rotating shaft 401 moves to the top or bottom of the sliding groove 14, the telescopic bracket 3 cannot continue to extend or contract. If the motor 2 continues to drive the telescopic bracket 3 to extend or contract, the motor 2 is easily stuck and damaged.

[0037] In order to prevent the motor 2 from being damaged, when the first rotating shaft 401 slides to the bottom of the sliding groove 14, the motor 2 stops operating to protect the motor 2.

[0038] As Figures 2 - 4 shown, the rotating shaft of the motor 2 is connected with a connecting shaft 21. The connecting shaft 21 passes through the fixing bracket 11 so that the fixing bracket 11 supports the rotation of the connecting shaft 21. The two ends of the telescopic bracket 3 in the width direction are respectively provided with a first collar 32 and a second collar 33. The first collar 32 and the second collar 33 are respectively sleeved on the outer periphery of the connecting shaft 21. The first collar 32 is slidably connected with the connecting shaft 21, and the second collar 33 is threadedly connected with the connecting shaft 21.

[0039] It should be noted that the connecting shaft 21 is provided with an external thread, and the second collar 33 is provided with an internal thread, and the external thread meshes with the internal thread; the motor 2 drives the connecting shaft 21 to rotate, and under the interaction of the internal thread and the external thread, the second collar 33 moves linearly along the connecting shaft 21.

[0040] In some embodiments, as Figure 3 shown, the connecting shaft 21 is provided with a threaded section 211, and the second collar 33 is sleeved on the threaded section 211. The length of the threaded section 211 can limit the movement range of the second collar 33 to prevent the second collar 33 from moving excessively and reducing the reliability of the operation of the holding ring 4. When the second collar 33 disengages from the threaded section 211, the second collar 33 generally cannot move linearly with the rotation of the connecting shaft 21.

[0041] As Figure 1 shown, the ocean observation detection equipment 5 is equipped with a parachute. During the falling process of the ocean observation detection equipment 5, the parachute opens to reduce the falling speed of the ocean observation detection equipment 5, so that the ocean observation detection equipment 5 can land smoothly at the designated position; the ocean observation detection equipment 5 is provided with a receiving cavity 51 for receiving the parachute; the parachute is connected to one end of the ocean observation detection equipment 5 where the receiving cavity 51 is provided; the parachute is connected to the base 1 through a rope 53. When the ocean observation detection equipment 5 is not released, the parachute is stored in the receiving cavity 51; when the ocean observation detection equipment 5 is released, the parachute is pulled out of the receiving cavity 51 under the pulling force of the rope 53, so that the parachute is opened.

[0042] In some embodiments, the receiving cavity 51 is a cavity provided at the end of the ocean observation detection equipment 5, and the parachute is received in the cavity.

[0043] It should be noted that the rope 53 can be connected to the parachute through a slipknot. When the ocean observation detection equipment 5 is released, the rope 53 first pulls the parachute out of the receiving cavity 51, and then applies a certain pulling force to the ocean observation detection equipment 5 to delay the falling of the end of the ocean observation detection equipment 5 where the receiving cavity 51 is provided.

[0044] When the ocean observation detection equipment 5 is clamped by the holding ring 4, the ocean observation detection equipment 5 is arranged horizontally to reduce the occupied space of the ocean observation detection equipment 5 and facilitate the loading of the ocean observation detection equipment 5 by the above-mentioned ocean observation detection equipment airdropping device.

[0045] Since the parachute is connected to the base 1 by the rope 53, under the pulling force of the rope 53, the end of the ocean observation and detection equipment 5 where the parachute is installed will delay the fall of the end of the ocean observation and detection equipment 5 where the parachute is not installed. Such a design can, on the one hand, facilitate the opening of the parachute and ensure the reliability of the parachute's operation; on the other hand, it can make the ocean observation and detection equipment 5 fall in a vertical state, reduce other resistances suffered by the ocean observation and detection equipment 5 during the falling process, and ensure that the ocean observation and detection equipment 5 can accurately fall to the designated position.

[0046] In some embodiments, the ocean observation and detection equipment 5 is generally in a long strip and circular structure. During the falling process of the ocean observation and detection equipment 5, the end of the ocean observation and detection equipment 5 where the parachute is not installed is located below the end of the ocean observation and detection equipment 5 where the parachute is installed.

[0047] In some other embodiments, the end of the ocean observation and detection equipment 5 where the parachute is not installed is designed as a smooth tip to reduce the resistance suffered by the ocean observation and detection equipment 5 during the landing process.

[0048] As Figure 1 and Figure 2 shown, the base 1 is provided with a hook 12. The hook 12 is located on the lower side of the base 1, and the rope 53 is connected to the hook 12.

[0049] The outer periphery of the ocean observation and detection equipment 5 is provided with a convex portion 52. The convex portion 52 is arranged close to the accommodation cavity 51; the base 1 is provided with a positioning portion 15. The positioning portion 15 is located at the bottom of the base 1. The bottom of the positioning portion 15 is provided with a positioning notch. The two side walls of the positioning notch are along the two sides of the length direction of the ocean observation and detection equipment 5, and the convex portion 52 is arranged in the positioning notch. Through the mutual cooperation of the convex portion 52 and the positioning portion 15, the axial direction of the ocean observation and detection equipment 5 is positioned to prevent the ocean observation and detection equipment 5 from moving along its axial direction during the process of the unmanned aerial vehicle carrying the ocean observation and detection equipment 5.

[0050] As Figure 3 and Figure 4 shown, the telescopic frame 3 includes four connecting bars 31. The four connecting bars 31 are rotatably connected to each other to form a quadrilateral structure; the connecting bars 31 are arranged in the horizontal direction, and adjacent two connecting bars 31 are connected to each other through a rotating member 301; the first collar 32 and the second collar 33 are correspondingly connected to two rotating members 301 in the width direction of the telescopic frame 3; two clamping members 41 are correspondingly connected to two rotating members 301 in the length direction of the telescopic frame 3.

[0051] It should be noted that when the telescopic frame 3 extends, the two rotating members 301 in the width direction of the telescopic frame 3 move away from each other along the axial direction of the connecting shaft 21; when the telescopic frame 3 contracts, the two rotating members 301 in the width direction of the telescopic frame 3 move closer to each other along the axial direction of the connecting shaft 21.

[0052] In this embodiment, the quadrilateral structure is a rhombus structure to make the movement of the telescopic frame 3 more reliable.

[0053] As Figure 3 and Figure 4 shown, the fixed frame 11 is provided with a limiting groove 111, the direction of the limiting groove 111 extends along the axial direction of the connecting shaft 21, a limiting portion is provided at the lower end of the rotating member 301 in the width direction of the telescopic frame 3, the limiting portion is arranged in the limiting groove 111, when the telescopic frame 3 expands and contracts, the limiting portion slides along the limiting groove 111, through the mutual cooperation of the limiting portion and the limiting groove 111, the movement of the connecting bar 31 is restricted, and the connecting bar 31 is prevented from moving out of position along the direction intersecting the axial direction of the connecting shaft 21, so as to ensure the reliability and stability of the telescopic movement of the telescopic frame 3.

[0054] In the above-mentioned air-dropping device for marine observation equipment, as Figure 5 and Figure 6 shown, it further includes a controller 6, the controller 6 is connected to the motor 2, and the controller 6 is configured to: control the rotation of the motor 2 to make the telescopic frame 3 contract or release, so as to make the clamping ring 4 clamp or release the marine observation equipment 5.

[0055] As Figure 5 and Figure 6 shown, the controller 6 is located inside the unmanned aerial vehicle, and the base 1 is located outside the unmanned aerial vehicle to facilitate the loading or release of the marine observation equipment 5.

[0056] In the prior art, the unmanned aerial vehicle only has hanging points under the wings, the number of load-bearing and hanging points is small, and it is impossible to hang the marine observation equipment 5 with a large load, resulting in the inability of the unmanned transport aircraft to transport the marine observation equipment 5 to the position above the designated location. And for the unmanned transport aircraft with a large load, objects are usually transported in the cabin, resulting in the inability to deploy the marine observation equipment 5 by air-dropping.

[0057] Based on this, in the present invention, by arranging a connecting frame 82 on the cabin floor 8, the connecting frame 82 is located on the cabin floor 8, and a load-bearing beam 81 is arranged above the connecting frame 82, and the load-bearing beam 81 is used to press the connecting frame 82 to increase the firmness of the connection between the connecting frame 82 and the cabin floor 8; and a connecting rod 9 is arranged, the upper end of the connecting rod 9 is connected to the load-bearing beam 81, and the lower end of the connecting rod 9 passes through the cabin floor 8 and is connected to the base 1, so that the base 1 is installed on the abdomen of the unmanned aerial vehicle and located outside the abdomen of the unmanned aerial vehicle, so as to facilitate the air-dropping of the marine observation equipment 5.

[0058] It should be noted that the controller 6 is placed on the connecting frame 82, and a mounting frame 7 is provided at the top of the controller 6, and the mounting frame 7 is connected to the cabin floor 8 through fasteners such as bolts or screws.

[0059] In some embodiments, as Figure 7As shown, the connecting rod 9 is light in weight and suitable for external loads with lower loads.

[0060] In some other embodiments, such as Figure 8 As shown, the connecting rod 9 has a reinforcing rod 91 in the longitudinal direction and can bear a large load without tremors.

[0061] When the first rotating shaft 401 slides to the bottom of the chute 14, the first rotating shaft 401 cannot continue to move downward, and the telescopic frame 3 cannot continue to extend. At this time, if the motor 2 continues to drive the telescopic frame 3 to extend, the motor 2 is likely to be damaged. Therefore, to prevent the motor 2 from being damaged, the controller 6 is further configured to: when the first rotating shaft 401 slides to the bottom of the chute 14, control the motor 2 to stop running.

[0062] It should be noted that the fixing part 13 may be equipped with a distance sensor for detecting the distance of the first rotating shaft 401. The distance sensor is connected to the controller 6, and the controller 6 determines whether the first rotating shaft 401 slides to the bottom of the chute 14 according to the detection information of the distance sensor, so as to determine whether to control the motor 2 to stop running.

[0063] The control principle of the controller 6 is: when receiving the instruction to open the clamping ring 4, control the motor 2 to rotate, so that the telescopic frame 3 contracts, so that the lower ends of the two clamping members 41 rotate in a direction away from each other; when receiving the instruction to close the clamping ring 4, control the motor 2 to rotate in the reverse direction, so that the telescopic frame 3 extends, so that the lower ends of the two clamping members 41 rotate in a direction close to each other; when the first rotating shaft 401 slides to the bottom of the chute 14, control the motor 2 to stop running to protect the motor 2 and prevent the motor 2 from being stuck.

[0064] In some embodiments, the controller 6 is also the controller 6 of the unmanned aerial vehicle. Such as Figure 10 As shown, the position information and / or navigation information of the unmanned aerial vehicle are input into the controller 6 in advance. The controller 6 is configured to: when the position of the unmanned aerial vehicle reaches the threshold, the controller 6 controls the motor 2 to start, and the motor 2 drives the connecting shaft 21 to rotate, so that the telescopic frame 3 extends, so that the clamping ring 4 opens to release the marine observation detection equipment 5. When the first rotating shaft 401 slides to the bottom of the chute 14, the controller 6 controls the motor 2 to stop running to prevent the motor 2 from being burned due to being stuck.

[0065] It should be noted that the unmanned aerial vehicle flies to the designated position according to the preset flight path, so as to airdrop the marine observation detection equipment. In some embodiments, it is judged whether the unmanned aerial vehicle flies to the designated position by observing whether the position reached after the unmanned aerial vehicle flies is within the set threshold.

[0066] In some embodiments, the marine observation and detection equipment 5 is relatively large in size, and multiple holding rings 4 can be designed. The multiple holding rings 4 are arranged axially along the connecting shaft 21. Correspondingly, multiple telescopic frames 3 are also designed. The multiple telescopic frames 3 are arranged in one-to-one correspondence with the multiple holding rings 4. The multiple telescopic frames 3 are connected to the same connecting shaft 21, so that the same motor 2 drives the multiple telescopic frames 3 to expand and contract, and thus the multiple holding rings 4 work synchronously.

[0067] In other embodiments, a drone can be installed with multiple air-dropping devices for marine observation and detection equipment at the same time, so that the same drone can achieve the air-dropping of multiple marine observation and detection equipment 5. The multiple air-dropping devices for marine observation and detection equipment work independently of each other.

[0068] As Figure 10 shown, the drone is installed with a fairing. The fairing is located outside the drone and on the abdomen of the drone, and is used to cover components such as the base 1, the motor 2, and the telescopic frame 3, so as to reduce the air resistance when the drone is flying.

[0069] Based on the above-mentioned air-dropping device for marine observation and detection equipment, the present invention also provides a method for deploying marine observation and detection equipment. The marine observation and detection equipment 5 is deployed on the sea surface by using the above-mentioned air-dropping device for marine observation and detection equipment. The method for deploying marine observation and detection equipment includes the following steps: Install a parachute at one end of the marine observation and detection equipment 5 where the accommodation cavity 51 is provided, and store the parachute in the accommodation cavity 51. At the same time, connect the parachute to the base 1 through a rope 53. The motor 2 drives the telescopic frame 3 to extend, so that the lower ends of the two clamping members 41 rotate in a direction away from each other, and the holding ring 4 is in an open state. The marine observation and detection equipment 5 is horizontally placed in the holding ring 4, and then the motor 2 drives the telescopic frame 3 to contract, so that the holding ring 4 clamps the marine observation and detection equipment 5. The drone flies to a position above the designated location according to a preset route. The motor 2 drives the telescopic frame 3 to extend, so that the lower ends of the two clamping members 41 rotate in a direction away from each other to release the marine observation and detection equipment 5, so that the marine observation and detection equipment 5 falls to the designated location under the action of its own gravity and the parachute.

[0070] It should be noted that after the marine observation and detection equipment 5 is released, the end of the marine observation and detection equipment 5 where the accommodation cavity 51 is not provided falls first, and the end of the marine observation and detection equipment 5 where the accommodation cavity 51 is provided is delayed in falling under the pulling force of the rope 53, so that the marine observation and detection equipment 5 finally falls in a vertical posture.

[0071] The above-mentioned deployment method of ocean observation and detection equipment installs the aerial delivery device of ocean observation and detection equipment on the abdomen of the unmanned aerial vehicle (UAV), enabling the UAV to carry the ocean observation and detection equipment 5 to a position above the designated location. Then, the holding ring 4 releases the ocean observation and detection equipment 5, causing the ocean observation and detection equipment 5 to fall to the designated location, thus realizing the deployment of the ocean observation and detection equipment 5 in the ocean. Moreover, a parachute is installed on the ocean observation and detection equipment 5, enabling the ocean observation and detection equipment 5 to land steadily at the designated location, ensuring the accuracy of the falling position of the ocean observation and detection equipment 5 and also avoiding damage to the ocean observation and detection equipment 5 caused by its too fast falling speed. The deployment method of the ocean observation and detection equipment 5 is simple and easy to operate, and the deployment accuracy of the ocean observation and detection equipment 5 is high, and the ocean observation and detection equipment 5 is not easily damaged during the deployment process.

[0072] It should be noted that the ocean observation and detection equipment includes, but is not limited to, buoys. The ocean observation and detection equipment belongs to the well-known common sense technology in this field and will not be elaborated here.

[0073] The above-mentioned deployment method of ocean observation and detection equipment will be introduced in detail below in combination with the aerial delivery device of ocean observation and detection equipment, as Figure 11 shown, the above-mentioned deployment method of ocean observation and detection equipment includes the following steps: Preset the flight route of the UAV in the controller 6, install the above-mentioned aerial delivery device of ocean observation and detection equipment on the abdomen of the UAV, and make the holding ring 4 located outside the UAV; Install a parachute at one end of the accommodation cavity 51 of the ocean observation and detection equipment 5, and store the parachute in the accommodation cavity 51; at the same time, connect the rope 53 on the parachute to the base 1; Control the motor 2 to rotate, extend the telescopic frame 3, make the first rotating shaft 401 slide downward along the chute 14, open the holding ring 4, install the ocean observation and detection equipment 5 between the two clamping members 41, and then control the motor 2 to rotate in the reverse direction, contract the telescopic frame 3, make the first rotating shaft 401 slide upward along the chute 14, and close the holding ring 4, thereby clamping the ocean observation and detection equipment 5; Start the UAV to fly. When the UAV flies to a position above the designated location, control the motor 2 to rotate, extend the telescopic frame 3, make the first rotating shaft 401 slide downward along the chute 14, open the holding ring 4. The end of the ocean observation and detection equipment 5 without the accommodation cavity 51 falls first under the action of gravity, and the end of the ocean observation and detection equipment 5 with the accommodation cavity 51 delays falling under the pulling force of the rope 53. When the ocean observation and detection equipment 5 falls, the parachute is pulled out of the accommodation cavity 51 and the rope 53 is separated from the parachute; as the ocean observation and detection equipment 5 falls, the parachute is opened. Under the action of the parachute, the falling speed of the ocean observation and detection equipment 5 is reduced, so that the ocean observation and detection equipment 5 falls steadily, ensuring the reliability of the aerial deployment of the ocean observation and detection equipment 5.

[0074] Through the description of multiple embodiments of the aerial delivery device for ocean observation and detection equipment and the deployment method of ocean observation and detection equipment of the present invention, it can be seen that the embodiments of the aerial delivery device for ocean observation and detection equipment and the deployment method of ocean observation and detection equipment of the present invention have at least one or more of the following advantages: 1. By driving the telescopic frame 3 to expand and contract with the help of the motor 2, controlling the opening and closing of the clamping ring 4, so as to complete the clamping and releasing actions of the ocean observation and detection equipment 5, it can not only achieve precise control of the ocean observation and detection equipment 5, but also has high working reliability; the automatic control of the clamping ring 4 by the motor 2 avoids complex manual operations and uncontrollable factors, and greatly reduces the risk of operation errors.

[0075] 2. By installing a parachute on the ocean observation and detection equipment 5, using the parachute to reduce the falling speed of the ocean observation and detection equipment 5, avoiding damage to the ocean observation and detection equipment 5 caused by a large impact between the ocean observation and detection equipment 5 and the water surface due to too fast falling speed, and ensuring the reliability of the deployment of the ocean observation and detection equipment 5 by aerial delivery.
