Description

Technical Field

[0001] The present invention belongs to the technical field of ocean monitoring equipment, and in particular relates to an airdrop device for ocean observation and detection equipment and a deployment method thereof. Background Art

[0002] Ocean observation and detection equipment is crucial for marine environmental monitoring, meteorological observation, and waterway marking. The efficiency and safety of its deployment directly impact the quality of ocean data. Traditionally, deployment of ocean observation and detection equipment relies primarily on vessels. However, the vast oceans and complex, ever-changing sea conditions, coupled with slow vessel speeds, often require significant time and manpower for operation and maintenance, resulting in low overall efficiency.

[0003] With the development of drones, more and more ocean observation and detection equipment are being deployed by drone airdrop. Drones have the advantages of high flight speed and long range, and can efficiently and safely complete the deployment of a large number of ocean observation and detection equipment, and can smoothly complete the deployment work without external interference. However, in existing technologies, the fixing and release mechanism structure of the ocean observation and detection equipment in the device used to airdrop ocean observation and detection equipment is relatively complex, and the working reliability is low. The ocean observation and detection equipment is prone to jamming when released, which may cause the ocean observation and detection equipment to miss the optimal release position, resulting in the ocean observation and detection equipment being far away from the designated position when it falls on the water surface, affecting the collection effect of the ocean observation and detection equipment. In addition, the ocean observation and detection equipment is in a free fall state in the air when it is airdropped, causing it to fall to the sea surface at a high speed. The instant it comes into contact with seawater will generate a large pressure, which can easily damage the ocean observation and detection equipment, thereby affecting the normal use of the ocean observation and detection equipment and the accuracy of data collection.

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

[0005] In response to the shortcomings in the relevant technologies, the present invention provides an airdrop device and deployment method for ocean observation and detection equipment to simplify the structure of the airdrop device for ocean observation and detection equipment and increase the accuracy of the airdrop of ocean observation and detection equipment.

[0006] The present invention provides an airdrop device for ocean observation and detection equipment, which is installed on an unmanned aerial vehicle (UAV); the airdrop device for ocean observation and detection equipment includes:

[0007] A base is detachably connected to the belly of the drone; a fixing frame is connected below the base;

[0008] The holding ring is used to clamp the ocean observation and detection equipment; the holding ring includes a clamping member, the upper end of which is rotatably connected to the fixing frame; the clamping members are provided with two, 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 are rotated in a direction toward each other, the ocean observation and detection equipment is clamped; when the lower ends of the two clamping members are rotated in a direction away from each other, the ocean observation and detection equipment is released;

[0009] The telescopic frame can be extended and retracted along the width direction of the telescopic frame to adjust the length of the telescopic frame; the two ends of the telescopic frame in the length direction are respectively provided with two clamping members; the telescopic frame is connected to the upper ends of the clamping members; when the telescopic frame is retracted, the lower ends of the two clamping members rotate in a direction toward each other; when the telescopic frame is extended, the lower ends of the two clamping members rotate in a direction away from each other;

[0010] The motor is installed on the base and is used to drive the telescopic frame to extend and retract.

[0011] This technical solution enables the base to be detachably connected to the belly of the drone, so that the ocean observation and detection equipment airdrop device can be installed on the drone or disassembled from the drone according to actual needs; by designing the holding ring to include two clamping parts, the two clamping parts are arranged relative to each other in a circumferential direction and rotatably connected to each other, thereby realizing the clamping and release of the ocean observation and detection equipment, and using a motor to drive the telescopic frame to telescope and control the rotation of the clamping parts, not only can the holding ring reliably fix the ocean observation and detection equipment and increase the reliability of the holding ring, but also realizes the automatic control of the holding ring, avoids complex manual operation, reduces the risk of operational errors, and improves work reliability. At the same time, the overall structure is simple, easy to implement and maintain, and can use the drone to accurately carry the ocean observation and detection equipment to the designated position and release it, meeting the needs of deploying ocean observation and detection equipment in ocean monitoring.

[0012] In some embodiments, a accommodating cavity is provided at one end of the ocean observation and detection equipment, and the accommodating cavity is used to store a parachute; the parachute is connected to one end of the accommodating cavity of the ocean observation and detection equipment, 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 accommodating cavity under the action of the tension of the rope.

[0013] This technical solution installs a parachute on the ocean observation and detection equipment so that the ocean observation and detection equipment falls slowly under the action of the parachute, reduces the falling speed of the ocean observation and detection equipment, and avoids the ocean observation and detection equipment from falling too fast and causing a large impact with the water surface, which may cause damage to the ocean observation and detection equipment; by providing a accommodating cavity, the parachute is stored in the accommodating cavity, and the parachute is connected to the base through a rope, so that when the ocean observation and detection equipment is released, the parachute can be pulled out of the accommodating cavity under the tension of the rope and the gravity of the ocean observation and detection equipment, thereby releasing the restraint of the accommodating cavity on the parachute.

[0014] In some embodiments, the rotating shaft of the motor is connected to a connecting shaft; the connecting shaft is arranged through a fixed frame so that the fixed frame supports the rotation of the connecting shaft; a first ring and a second ring are provided at both ends of the telescopic frame in the width direction, and the first ring and the second ring are respectively sleeved on the outer circumference of the connecting shaft, the first ring is slidably connected to the connecting shaft, and the second ring is threadedly connected to the connecting shaft.

[0015] In some embodiments, the telescopic frame includes four connecting bars, which are rotatably connected to each other to form a quadrilateral structure. The connecting bars are arranged in a horizontal direction, and two adjacent connecting bars are connected to each other through a rotating member; the first ring and the second ring are correspondingly connected to the two rotating members in the width direction of the telescopic frame; and the two clamping members are correspondingly connected to the two rotating members in the length direction of the telescopic frame.

[0016] In some 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 the other clamping member are close to each other, and the first connecting portion is rotatably connected to the fixed frame and the other clamping member; the second connecting portion is located obliquely above the first connecting portion, and the second connecting portion 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.

[0017] In some embodiments, the two clamping members are rotatably connected to each other via a first rotating shaft; a fixing portion is provided at the bottom of the fixing frame, the first rotating shaft passes through the fixing portion, and the clamping members and the fixing portion are rotatably connected to each other via the first rotating shaft.

[0018] In some embodiments, a slide groove is provided on the fixed portion and is arranged in the vertical direction; the first rotating shaft can slide up and down along the slide groove; when the first rotating shaft slides downward, the telescopic frame extends; when the first rotating shaft slides upward, the telescopic frame contracts.

[0019] In some embodiments, a controller is further included, the controller being connected to the motor, and the controller being configured to: control the motor to rotate so as to retract or extend the telescopic frame, thereby causing the holding ring to clamp or release the ocean observation and detection equipment;

[0020] When the first rotating shaft slides to the bottom of the sliding groove, the motor is controlled to stop running.

[0021] In addition, the present invention also provides a method for deploying ocean observation and detection equipment, which uses the above-mentioned ocean observation and detection equipment airdrop device to deploy the ocean observation and detection equipment on the sea surface; the method for deploying the ocean observation and detection equipment includes the following steps:

[0022] A parachute is installed at one end of the receiving cavity of the ocean observation and detection equipment, and the parachute is stored in the receiving cavity; and the parachute is connected to the base through a rope;

[0023] The motor drives the telescopic frame to extend, causing the lower ends of the two clamping parts to rotate away from each other, so that the holding ring is in an open state, and the ocean observation and detection equipment is placed in the holding ring in a horizontal direction. Then the motor drives the telescopic frame to retract, so that the holding ring clamps the ocean observation and detection equipment;

[0024] After the drone flies to the designated position along the preset route, the motor drives the telescopic frame to extend, causing the lower ends of the two clamping parts to rotate away from each other to release the ocean observation and detection equipment. The parachute is pulled out of the accommodation cavity under the tension of the rope and the gravity of the ocean observation and detection equipment; the ocean observation and detection equipment falls to the designated position under the action of its gravity and the parachute.

[0025] In some embodiments, after the ocean observation and detection equipment is released, the end of the ocean observation and detection equipment without the accommodating cavity falls first, and the end of the ocean observation and detection equipment with the accommodating cavity is delayed in falling under the tension of the rope, so that the ocean observation and detection equipment finally falls in a vertical posture.

[0026] Based on the above technical solution, the ocean observation and detection equipment airdrop device in the embodiment of the present invention drives the telescopic frame to extend and retract through a motor to control the holding ring to clamp or release the ocean observation and detection equipment, so that the ocean observation and detection equipment can be transported to the top of the designated position with the help of a drone, and then the holding ring releases the ocean observation and detection equipment, so that the ocean observation and detection equipment can be airdropped to the designated position; the overall structure is simple and the holding ring has a strong load capacity, which can realize the airdrop of larger-sized ocean observation and detection equipment.

[0051] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0052] In the description of the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying 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 operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0053] The terms "first," "second," and "third" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," or "third" may explicitly or implicitly include one or more of such features.

[0054] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0055] As attached Figures 1-6As shown, in an illustrative embodiment of the ocean observation and detection equipment airdrop device of the present invention, the ocean observation and detection equipment airdrop device is installed on a UAV; the ocean observation and detection equipment airdrop device includes a base 1, a holding ring 4, a telescopic frame 3 and a motor 2; the base 1 is detachably connected to the abdomen of the UAV; a fixing frame 11 is connected to the bottom of the base 1; the holding ring 4 is used to clamp the ocean observation and detection equipment 5; the holding ring 4 includes a clamping member 41, 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 relative to each other in the circumferential direction and are rotatably connected to each other; when the lower ends of the two clamping members 41 rotate in a direction close to each other , the ocean observation and detection equipment 5 is clamped; when the lower ends of the two clamping parts 41 rotate in the direction away from each other, the ocean observation and detection equipment 5 is released; the telescopic frame 3 can be extended and retracted along the width direction of the telescopic frame 3 to adjust the length of the telescopic frame 3, thereby driving the clamping parts 41 to rotate; the two ends of the telescopic frame 3 in the length direction are arranged in a one-to-one correspondence with the two clamping parts 41; the telescopic frame 3 is connected to the upper end of the clamping parts 41; when the telescopic frame 3 contracts, the lower ends of the two clamping parts 41 rotate in the direction of approaching each other; when the telescopic frame 3 extends, the lower ends of the two clamping parts 41 rotate in the direction away from each other; the motor 2 is installed on the base 1, and is used to drive the telescopic frame 3 to extend and retract.

[0056] It should be noted that when the telescopic frame 3 is extended, the length of the telescopic frame 3 is reduced and the width of the telescopic frame 3 is increased; when the telescopic frame 3 is retracted, the length of the telescopic frame 3 is increased and the width of the telescopic frame 3 is reduced.

[0057] For the sake of convenience, in this embodiment, rotating the lower ends of the two clamping members 41 toward each other is called closing the ring 4, and rotating the lower ends of the two clamping members 41 toward each other is called opening the ring 4.

[0058] The above-mentioned ocean observation and detection equipment airdrop device controls the opening or closing of the holding ring 4 by extending and retracting the telescopic frame 3, thereby realizing the clamping and release of the ocean observation and detection equipment 5; and a motor 2 is provided to control the extension and retraction of the telescopic frame 3 to realize the automatic opening and closing of the holding ring 4. The overall structure of the ocean observation and detection equipment airdrop device is simple, the control method of the holding ring 4 is simple, and the working reliability is high.

[0059] The operating steps of the above-mentioned ocean observation and detection equipment airdrop device for airdropping the ocean observation and 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 parts 41 rotate in the direction away from each other, so that the ring 4 is opened, and the ocean observation and detection equipment 5 is placed in the ring 4, and then the motor 2 drives the telescopic frame 3 to contract, so that the ring 4 clamps the ocean observation and detection equipment 5; when the UAV flies to the top of 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 parts 41 rotate in the direction away from each other, so that the ring 4 opens to release the ocean observation and detection equipment 5, so that the ocean observation and detection equipment 5 falls to the designated position under the action of gravity.

[0060] It should be noted that the motor 2 has a locking function. When the holding ring 4 clamps the ocean observation and detection equipment 5, the motor 2 is locked so that the holding ring 4 is always in a state of clamping the ocean observation and detection equipment 5, thereby ensuring the fixing effect of the ocean observation and detection equipment 5. Motors with a locking function belong to the existing technology in this field and will not be described in detail here.

[0061] like Figure 2-Figure 4 As shown, the two clamping members 41 are rotatably connected to each other via a first rotating shaft 401, and the clamping member 41 is rotatably connected to the telescopic frame 3 via 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, thereby realizing the rotation of the clamping member 41 controlled by the telescopic frame 3.

[0062] A first connecting portion and a second connecting portion are provided at the upper end of the clamping member 41. The first connecting portion is rotatably connected to the fixing frame 11 and the other clamping member 41 via a first rotating shaft 401, and the second connecting portion is rotatably connected to the telescopic frame 3 via a second rotating shaft 402. The first connecting portion is located on the side where the clamping member 41 and the other clamping member 41 are close to each other, and the second connecting portion is located obliquely above the first connecting portion, and the second connecting portion is located on the side where the two clamping members 41 are away from each other.

[0063] like Figure 2 As shown, the fixing frame 11 has a fixing portion 13 at its bottom, and a first rotating shaft 401 is disposed through the fixing portion 13, so that the clamping member 41 is rotatably connected to the fixing portion 13 via 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 achieved via the same first rotating shaft 401, which not only increases the reliability and stability of the movement of the clamping members 41 but also simplifies the overall structure.

[0064] like Figure 3 and Figure 4 As shown, a slide groove 14 is provided on the fixing portion 13, and the slide groove 14 is arranged in the vertical direction; the first rotating shaft 401 can slide up and down along the slide groove 14; when the telescopic frame 3 is extended, the first rotating shaft 401 slides downward; when the telescopic frame 3 is retracted, the first rotating shaft 401 slides upward.

[0065] It should be noted that the slide groove 14 also increases the rotation angle of the clamping member 41, so that the ring 4 can clamp the ocean observation and detection equipment 5 with a larger diameter.

[0066] It should also be noted that the top and bottom of the slide groove 14 respectively limit the sliding of the first rotating shaft 401. When the first rotating shaft 401 moves to the top of the slide groove 14 or the bottom of the slide groove 14, the telescopic frame 3 cannot continue to extend or retract. If the motor 2 continues to drive the telescopic frame 3 to extend or retract, the motor 2 is likely to get stuck and damaged.

[0067] 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 running to protect the motor 2 .

[0068] like Figure 2-Figure 4 As shown, the rotating shaft of the motor 2 is connected to the connecting shaft 21; the connecting shaft 21 is arranged through the fixing frame 11 so that the fixing frame 11 supports the rotation of the connecting shaft 21; the two ends of the telescopic frame 3 in the width direction are correspondingly provided with a first ring 32 and a second ring 33, and the first ring 32 and the second ring 33 are respectively sleeved on the outer periphery of the connecting shaft 21, the first ring 32 is slidably connected to the connecting shaft 21, and the second ring 33 is threadedly connected to the connecting shaft 21.

[0069] It should be noted that the connecting shaft 21 is provided with an external thread, and the second ring 33 is provided with an internal thread, and the external thread and the internal thread are engaged with each other; the motor 2 drives the connecting shaft 21 to rotate, and under the mutual cooperation of the internal thread and the external thread, the second ring 33 moves linearly along the connecting shaft 21.

[0070] In some embodiments, as Figure 3 As 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 limits the range of motion of the second collar 33, thereby preventing excessive movement of the second collar 33 and reducing the reliability of the holding ring 4. When the second collar 33 is disengaged from the threaded section 211, the second collar 33 is generally unable to move linearly with the rotation of the connecting shaft 21.

[0071] like Figure 1 As shown, the ocean observation and detection equipment 5 is equipped with a parachute. During the descent of the ocean observation and detection equipment 5, the parachute deploys to reduce the descent speed of the ocean observation and detection equipment 5, allowing the ocean observation and detection equipment 5 to land smoothly at the designated location. The ocean observation and detection equipment 5 is provided with a receiving cavity 51 for storing the parachute. The parachute is connected to one end of the ocean observation and detection equipment 5 where the receiving cavity 51 is located. The parachute is connected to the base 1 via a rope 53. When the ocean observation and detection equipment 5 is not released, the parachute is stored in the receiving cavity 51. When the ocean observation and detection equipment 5 is released, the parachute is pulled out of the receiving cavity 51 under the tension of the rope 53, thereby deploying the parachute.

[0072] In some embodiments, the accommodating cavity 51 is a cavity provided at the end of the ocean observation and detection equipment 5, and the parachute is accommodated in the cavity.

[0073] It should be noted that the rope 53 can be connected to the parachute through a snap hook. When the ocean observation and detection equipment 5 is released, the rope 53 first pulls the parachute out of the accommodating cavity 51, and then applies a certain pulling force to the ocean observation and detection equipment 5, so that the end of the ocean observation and detection equipment 5 where the accommodating cavity 51 is set is delayed in falling.

[0074] When the ocean observation and detection equipment 5 is clamped by the holding ring 4, the ocean observation and detection equipment 5 is arranged in the horizontal direction to reduce the space occupied by the ocean observation and detection equipment 5, making it convenient for the above-mentioned ocean observation and detection equipment airdrop device to load the ocean observation and detection equipment 5.

[0075] Since the parachute is connected to the base 1 through the rope 53, under the tension of the rope 53, the end of the ocean observation and detection equipment 5 where the parachute is installed will delay the falling of the end of the ocean observation and detection equipment 5 where the parachute is not installed. On the one hand, such a design can 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 resistance encountered 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.

[0076] In some embodiments, the ocean observation and detection equipment 5 is roughly long and has a circular structure. During the falling process of the ocean observation and detection equipment 5, the end of the ocean observation and detection equipment 5 without the parachute installed is located below the end of the ocean observation and detection equipment 5 with the parachute installed.

[0077] In other embodiments, the end of the ocean observation and detection equipment 5 where the parachute is not installed is designed to be a smooth tip to reduce the resistance encountered by the ocean observation and detection equipment 5 during landing.

[0078] like Figure 1 and Figure 2 As shown, the base 1 is provided with a hook 12 , which is located on the lower side of the base 1 , and the rope 53 is connected to the hook 12 .

[0079] The ocean observation and detection equipment 5 is provided with a raised portion 52 on its outer periphery, positioned adjacent to the accommodating cavity 51. The base 1 is provided with a positioning portion 15, located at the bottom of the base 1. The bottom of the positioning portion 15 is provided with a positioning notch, with two side walls extending along the length of the ocean observation and detection equipment 5, within which the raised portion 52 is positioned. The interaction between the raised portion 52 and the positioning portion 15 allows the ocean observation and detection equipment 5 to be positioned axially, preventing it from shifting axially while being carried by the drone.

[0080] like Figure 3 and Figure 4As shown, the telescopic frame 3 includes four connecting bars 31, which are rotatably connected to each other to form a quadrilateral structure; the connecting bars 31 are arranged in the horizontal direction, and two adjacent connecting bars 31 are connected to each other through a rotating member 301; the first ring 32 and the second ring 33 are correspondingly connected to the two rotating members 301 in the width direction of the telescopic frame 3; and the two clamping members 41 are correspondingly connected to the two rotating members 301 in the length direction of the telescopic frame 3.

[0081] It should be noted that when the telescopic frame 3 is extended, the two rotating parts 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 is retracted, the two rotating parts 301 in the width direction of the telescopic frame 3 move toward each other along the axial direction of the connecting shaft 21.

[0082] In this embodiment, the quadrilateral structure is a prismatic structure, so that the telescopic frame 3 can move more reliably.

[0083] like Figure 3 and Figure 4 As shown, the fixed frame 11 is provided with a limiting groove 111, and 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 located in the width direction of the telescopic frame 3, and the limiting portion is arranged in the limiting groove 111. When the telescopic frame 3 is extended or retracted, the limiting portion slides along the limiting groove 111. The limiting portion and the limiting groove 111 cooperate with each other to limit the movement of the connecting strip 31, thereby preventing the connecting strip 31 from being misplaced and moving in a direction intersecting with 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.

[0084] In the above-mentioned ocean observation and detection equipment airdrop device, Figure 5 and Figure 6 As shown, it also includes a controller 6, which is connected to the motor 2. The controller 6 is configured to: control the rotation of the motor 2 to shrink or release the telescopic frame 3, so that the holding ring 4 clamps the ocean observation and detection equipment 5 or releases the ocean observation and detection equipment 5.

[0085] like Figure 5 and Figure 6 As shown, the controller 6 is located inside the UAV and the base 1 is located outside the UAV to facilitate loading or releasing the ocean observation and detection equipment 5.

[0086] In existing technology, drones only have attachment points under their wings, which can carry a limited number of payloads. This makes it impossible to carry the heavier ocean observation equipment 5, which results in the UAV being unable to transport the ocean observation equipment 5 to the designated location. UAVs with large payloads typically carry objects within their cabins, making it impossible to deploy the ocean observation equipment 5 by airdrop.

[0087] Based on this, in the present invention, a connecting frame 82 is set on the cabin floor 8, so that the connecting frame 82 is located on the cabin floor 8, and a load-bearing beam 81 is set 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 set, so that 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 belly of the UAV and is located on the outside of the belly of the UAV, so as to facilitate the airdrop of the ocean observation and detection equipment 5.

[0088] It should be noted that the controller 6 is placed on the connection frame 82, and a mounting bracket 7 is provided on the top of the controller 6. The mounting bracket 7 is connected to the cabin bottom plate 8 by fasteners such as bolts or screws.

[0089] In some embodiments, as Figure 7 As shown, the connecting rod 9 is light in weight and suitable for external objects with lower loads.

[0090] In other embodiments, Figure 8 As shown, the connecting rod 9 has a reinforcing rod 91 in the longitudinal direction, which can withstand a large load without generating vibration.

[0091] Since the first rotating shaft 401 cannot continue to move downward when it slides to the bottom of the slide groove 14, 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 easily damaged. Therefore, in order 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 slide groove 14, the motor 2 is controlled to stop running.

[0092] It should be noted that the fixed part 13 can be installed with a distance sensor for detecting the distance of the first rotating shaft 401. The distance sensor is connected to the controller 6. The controller 6 determines whether the first rotating shaft 401 slides to the bottom of the slide groove 14 based on the detection information of the distance sensor, thereby determining whether to control the motor 2 to stop running.

[0093] The control principle of the controller 6 is as follows: when receiving an instruction to open the holding ring 4, the motor 2 is controlled 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 an instruction to close the holding ring 4, the motor 2 is controlled to rotate in the opposite direction, so that the telescopic frame 3 extends, so that the lower ends of the two clamping members 41 rotate in a direction toward each other; when the first rotating shaft 401 slides to the bottom of the slide groove 14, the motor 2 is controlled to stop running to protect the motor 2 and prevent the motor 2 from getting stuck.

[0094] In some embodiments, the controller 6 is also the controller 6 of the drone. Figure 10As shown, the position information and / or navigation information of the UAV is input into the controller 6 in advance, and the controller 6 is configured as follows: when the position of the UAV reaches a 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, thereby opening the holding ring 4 to release the ocean observation and detection equipment 5. When the first rotating shaft 401 slides to the bottom of the slide groove 14, the controller 6 controls the motor 2 to stop running to prevent the motor 2 from being stuck and burned.

[0095] It should be noted that the drone flies to the designated location according to the preset route to airdrop the ocean observation and detection equipment. In some embodiments, the drone is judged whether it has flown to the designated location by observing whether the location reached by the drone after the flight is within the set threshold.

[0096] In some embodiments, the ocean observation and detection equipment 5 is larger in size, and the holding ring 4 can be designed to be multiple, and the multiple holding rings 4 are arranged axially along the connecting shaft 21; accordingly, the telescopic frame 3 is also designed to be multiple, and the multiple telescopic frames 3 are arranged in a 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 extend and retract, thereby making the multiple holding rings 4 work synchronously.

[0097] In other embodiments, the drone may be equipped with multiple ocean observation and detection equipment airdrop devices at the same time, so that the same drone can achieve the airdrop of multiple ocean observation and detection equipment 5; the multiple ocean observation and detection equipment airdrop devices work independently of each other.

[0098] like Figure 10 As shown, the drone is equipped with a fairing, which is located outside the drone and on the belly of the drone, and is used to cover components such as the base 1, the motor 2, and the telescopic frame 3 to reduce the air resistance of the drone during flight.

[0099] Based on the above-mentioned ocean observation and detection equipment airdrop device, the present invention also provides a method for deploying ocean observation and detection equipment, using the above-mentioned ocean observation and detection equipment airdrop device to deploy ocean observation and detection equipment 5 on the sea surface; the method for deploying ocean observation and detection equipment includes the following steps:

[0100] A parachute is installed at one end of the accommodating cavity 51 of the ocean observation and detection equipment 5, and the parachute is stored in the accommodating cavity 51; at the same time, the parachute is connected to the base 1 through a rope 53;

[0101] The motor 2 drives the telescopic frame 3 to extend, causing the lower ends of the two clamping members 41 to rotate away from each other, so that the holding ring 4 is in an open state, and the ocean observation and detection equipment 5 is placed in the holding ring 4 in a horizontal direction. Then, the motor 2 drives the telescopic frame 3 to retract, so that the holding ring 4 clamps the ocean observation and detection equipment 5;

[0102] The UAV flies to the top of the designated position according to the preset route, and the motor 2 drives the telescopic frame 3 to extend, so that the lower ends of the two clamping parts 41 rotate away from each other to release the ocean observation and detection equipment 5, so that the ocean observation and detection equipment 5 falls to the designated position under the action of its gravity and the parachute.

[0103] It should be noted that after the ocean observation and detection equipment 5 is released, the end of the ocean observation and detection equipment 5 without the accommodating cavity 51 falls first, and the end of the ocean observation and detection equipment 5 with the accommodating cavity 51 is delayed in falling under the tension of the rope 53, so that the ocean observation and detection equipment 5 finally falls in a vertical posture.

[0104] The above-mentioned method for deploying ocean observation and detection equipment is to install the ocean observation and detection equipment airdrop device on the belly of the drone, so that the drone carries the ocean observation and detection equipment 5 to the top of the designated position, and then releases the ocean observation and detection equipment 5 by the holding ring 4, so that the ocean observation and detection equipment 5 falls to the designated position, thereby realizing the deployment of the ocean observation and detection equipment 5 in the ocean; and install a parachute on the ocean observation and detection equipment 5, so that the ocean observation and detection equipment 5 falls steadily at the designated position, 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 due to the ocean observation and detection equipment 5 falling too fast; the method for deploying 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.

[0105] It should be noted that ocean observation and detection equipment includes but is not limited to buoys. Ocean observation and detection equipment is common knowledge in this field and will not be described in detail here.

[0106] The following will introduce the deployment method of the above-mentioned ocean observation and detection equipment in detail in combination with the ocean observation and detection equipment airdrop device, such as Figure 11 As shown, the deployment method of the above-mentioned ocean observation and detection equipment includes the following steps:

[0107] The drone's flight path is preset in the controller 6, and the above-mentioned ocean observation and detection equipment airdrop device is installed on the belly of the drone, so that the holding ring 4 is located outside the drone;

[0108] A parachute is installed at one end of the receiving cavity 51 of the ocean observation and detection equipment 5, and the parachute is stored in the receiving cavity 51; at the same time, a rope 53 on the parachute is connected to the base 1;

[0109] The motor 2 is controlled to rotate to extend the telescopic frame 3, causing the first rotating shaft 401 to slide downward along the slide groove 14, and the holding ring 4 to open, so that the ocean observation and detection equipment 5 is installed between the two clamping members 41. Then, the motor 2 is controlled to rotate in the opposite direction to retract the telescopic frame 3, causing the first rotating shaft 401 to slide upward along the slide groove 14, and the holding ring 4 to close, thereby clamping the ocean observation and detection equipment 5.

[0110] Start the drone flight. When the drone flies above the specified position, control the motor 2 to rotate, extend the telescopic frame 3, slide the first rotating shaft 401 downward along the slide groove 14, and open the holding ring 4. The end of the ocean observation and detection equipment 5 without the accommodating chamber 51 falls first under the action of gravity, and the end of the ocean observation and detection equipment 5 with the accommodating chamber 51 is delayed in falling under the tension of the rope 53. When the ocean observation and detection equipment 5 falls, the parachute is pulled out of the accommodating chamber 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 smoothly, ensuring the reliability of the airdrop deployment of the ocean observation and detection equipment 5.

[0111] Through the description of multiple embodiments of the ocean observation and detection equipment airdrop device and the ocean observation and detection equipment deployment method of the present invention, it can be seen that the embodiments of the ocean observation and detection equipment airdrop device and the ocean observation and detection equipment deployment method of the present invention have at least one or more of the following advantages:

[0112] 1. By using the motor 2 to drive the telescopic frame 3 to extend and retract, the opening and closing of the holding ring 4 are controlled, thereby completing the clamping and releasing actions of the ocean observation and detection equipment 5. This not only enables precise control of the ocean observation and detection equipment 5, but also has high working reliability; the automatic control of the holding ring 4 by the motor 2 avoids complex manual operations and uncontrollable factors, greatly reducing the risk of operational errors.

[0113] 2. By installing a parachute on the ocean observation and detection equipment 5, the parachute is used to reduce the falling speed of the ocean observation and detection equipment 5, so as to avoid the ocean observation and detection equipment 5 being damaged by a large impact with the water surface due to the high falling speed, thereby ensuring the reliability of the airdrop deployment of the ocean observation and detection equipment 5.

[0114] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0115] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to preferred embodiments, persons skilled in the art should understand that the specific implementation methods of the present invention may still be modified or some technical features may be replaced by equivalents without departing from the spirit of the technical solutions of the present invention, and all of these should fall within the scope of the technical solutions claimed for protection by the present invention.
