Description

Technical Field

[0001] This utility model relates to the field of shooting equipment technology, and in particular to a buoyancy device and shooting system. Background Technology

[0002] Underwater photography often requires the use of buoyancy devices to help stabilize or fix the shooting equipment. Traditional buoyancy devices typically use a hollow tube structure to suspend the equipment in water and are equipped with a bottom connection port for installing support devices.

[0003] However, traditional buoyancy devices can only assist the shooting equipment in achieving a certain angle of shooting in water, and cannot meet the user's need for multi-angle shooting in different usage scenarios.

[0004] The information disclosed above in the background art of this application is only used to understand the background of the concept of this application, and may contain information that does not constitute prior art. Utility Model Content

[0005] Therefore, it is necessary to provide a buoyancy device and a shooting system to address the above problems.

[0006] A buoyancy device comprising:

[0007] The main body is used for detachable connection to the shooting device;

[0008] A first connecting portion is disposed on the first end face of the main body;

[0009] The second connecting part is disposed on the second end face of the main body;

[0010] Both the first connecting part and the second connecting part are used for detachable connection with the support device;

[0011] Specifically, when the first connecting part is connected to the support device, the shooting device is vertically positioned relative to the direction of gravity; when the second connecting part is connected to the support device, the shooting device is horizontally positioned relative to the direction of gravity.

[0012] The aforementioned buoyancy device can achieve at least the following beneficial effects:

[0013] By designing a detachable main body for the shooting device, and providing a first connecting part and a second connecting part on the first and second end faces of the main body respectively, both the first and second connecting parts can be detachably connected to a support device. When the first connecting part is connected to the support device, the shooting device can maintain a vertical orientation relative to the direction of gravity. For example, when placed vertically on land or underwater, the support device fixes the main body through the first connecting part, keeping the shooting device in an upright position for vertical shooting. When the second connecting part is connected to the support device, the shooting device can maintain a horizontal orientation relative to the direction of gravity. For example, when placed horizontally on land or underwater, the support device fixes the main body through the second connecting part, keeping the shooting device in a horizontal position for level shooting. In other words, users can flexibly choose to connect either the first or second connecting part to the same support device according to their shooting needs, achieving flexible and convenient switching between vertical and horizontal shooting postures in different scenarios such as land and underwater.

[0014] In some embodiments, the main body includes a hollow buoyancy rod with an internal cavity and a mounting component. The mounting component includes a mounting part for detachably connecting to a shooting device and a telescopic part connected to the mounting part. The telescopic part is inserted into the cavity from one end of the buoyancy rod along the axial direction of the buoyancy rod and can extend and retract relative to the buoyancy rod. A first connecting part is located at the other end of the buoyancy rod, and a second connecting part is located at the mounting part. By placing the first connecting part at the other end of the buoyancy rod and the second connecting part at the mounting part, the combined structure of the buoyancy rod and the mounting component can achieve both vertical fixation via the first connecting part and horizontal fixation via the second connecting part, improving the installation flexibility of the shooting device in both vertical and horizontal fixing methods and its adaptability to different scenarios. The telescopic part, which can be inserted into the cavity from one end of the buoyancy rod along the axial direction of the buoyancy rod and extend and retract relative to the buoyancy rod, not only allows for flexible adjustment of the installation height of the shooting device but also changes the volume of the buoyancy rod's internal cavity through the telescopic movement of the telescopic part, thereby precisely adjusting the overall buoyancy of the buoyancy rod.

[0015] In some embodiments, the telescopic part is threadedly connected to the buoyancy bar and can rotate under external force to extend or retract relative to the buoyancy bar. By setting the telescopic part and the buoyancy bar as a threaded connection structure, the structural compactness between the buoyancy bar and the mounting component is maintained, while the telescopic part can achieve axial extension and retraction adjustment relative to the buoyancy bar through rotational movement under external force. This threaded connection method can not only precisely control the extension and retraction of the telescopic part and realize fine adjustment of the installation height of the shooting equipment, but also ensure the stability and reliability of the adjusted position through the self-locking characteristic of the thread.

[0016] In some embodiments, the second connecting portion is disposed radially on the mounting portion along the buoyancy bar. By disposing the second connecting portion radially on the mounting portion, the second connecting portion can directly provide a lateral fixing interface, thereby achieving stable horizontal fixing when the mounting portion is connected to the shooting equipment. This radial arrangement not only optimizes the structural layout of the mounting portion, making the functional integration of the second connecting portion and the mounting portion more compact, but also complements the first connecting portion's axial arrangement along the end of the buoyancy bar, enabling the buoyancy device to simultaneously meet the requirements of both vertical and lateral fixing methods.

[0017] In some embodiments, the main body further includes a fixing component disposed on the mounting portion, the fixing component being used to snap, magnetically connect, or thread-connect with the shooting device. By providing a fixing component on the mounting portion, the shooting device can be quickly fixed or disassembled with the mounting portion through snap-fit, magnetic connection, or threaded connection, thereby significantly improving the convenience of installing and disassembling the shooting device; the diverse connection methods of the fixing component can be flexibly selected according to different shooting needs, ensuring the reliability of the connection and enhancing the compatibility of the buoyancy device with shooting devices of different specifications, further expanding the adaptability of the application scenarios.

[0018] In some embodiments, the fixing assembly includes a knob rotatably connected to the mounting portion and a threaded connector connected to the knob. The knob is operated to drive the threaded connector into a threaded connection with the shooting device. The knob design is more user-friendly and easy for users to operate. The operator can rotate the knob to drive the threaded connector to form a threaded fastening with the shooting device. This mechanical linkage structure not only enables quick locking and unlocking of the shooting device, but also ensures the reliability of the fixing strength through the threaded connection.

[0019] In some embodiments, the buoyancy device further includes anti-rotation fins. The anti-rotation fins and the second connecting portion are respectively disposed on both sides of the mounting portion. The anti-rotation fins can move relative to the mounting portion to a folded state and an unfolded state. In the unfolded state, the anti-rotation fins prevent the buoyancy bar from rotating underwater due to water flow. The symmetrical arrangement of the anti-rotation fins and the second connecting portion on both sides of the mounting portion optimizes the overall force balance, allowing the buoyancy device to maintain precise control of the shooting angle even in complex water flow environments. The folded state of the anti-rotation fins reduces the overall size of the buoyancy device, facilitating storage. In the unfolded state, the anti-rotation fins effectively suppress the rotation of the buoyancy bar caused by water flow impact, ensuring the directional stability of the shooting equipment. The foldable design of the anti-rotation fins maintains a compact structure for easy storage when not in operation, and provides an anti-rotation effect when unfolded. Through simple mechanical action, it significantly improves underwater stability and optimizes shooting results.

[0020] In some embodiments, the anti-rotation fin is rotatably connected to the mounting portion and can rotate relative to the mounting portion to a folded state and an unfolded state. In the unfolded state, the length extension direction of the anti-rotation fin is approximately parallel to the radial direction of the mounting portion. In the folded state, the length extension direction of the anti-rotation fin is approximately parallel to the axial direction of the buoyancy bar. By rotatably connecting the anti-rotation fin to the mounting portion, the anti-rotation fin can rotate relative to the mounting portion to a folded state and an unfolded state. In the unfolded state, the length extension direction of the anti-rotation fin is approximately parallel to the radial direction of the mounting portion. This can be considered a biomimetic design to function similarly to a fish fin, effectively suppressing the rotation of the buoyancy bar underwater due to water flow and ensuring the orientation stability of the shooting device. In the folded state, the length extension direction of the anti-rotation fin is approximately parallel to the axial direction of the buoyancy bar. If the anti-rotation fin is folded into the outer circumference of the buoyancy bar, the overall size of the buoyancy device is reduced, making it easier to store and carry. This rotating connection structure achieves the switching of the anti-rotation fin state through simple mechanical action, satisfying the underwater anti-rotation function requirements while also considering the portability and ease of operation of the device.

[0021] In some embodiments, the support device is a tripod, or a telescopic pole, wherein the telescopic pole includes a tripod. By setting the support device as a tripod or a telescopic pole including a tripod, two different support structure options are provided. The tripod structure ensures stable planar support, while the telescopic pole structure combines height adjustment and support functions. The support device and the main body can be integrally fixed or detachably connected. Integral fixing ensures the overall structural robustness, while detachable connection facilitates disassembly, storage, carrying, transportation, and flexible replacement of different support devices to meet the needs of different usage scenarios.

[0022] In some embodiments, the support device includes a fastener and at least three support legs, one of which is provided with a support column. The remaining three support legs are rotatably fitted onto the support column and are movable to a folded position and an unfolded position. In the unfolded position, the at least three support legs are spaced apart circumferentially along the support column to support the object on a plane. In the folded position, the at least three support legs are stacked circumferentially along the support column. The fastener is located at one end of the support column along the axial direction and is threadedly connected to the main body of the buoyancy device. Fasteners are installed along the axial direction of the support column and threadedly connected to the main body of the buoyancy device to ensure a stable connection between the support device and the main body. At least three support legs can rotate relative to each other along the circumference of the support column and can switch between a folded position and an unfolded position. When unfolded, at least three support legs are spaced apart along the circumference of the support column to form a stable planar support structure. When folded, at least three support legs are stacked along the circumference of the support column to reduce the space occupied. This structural design not only ensures the stability of the support device in the unfolded state, but also achieves compact storage of the device through the foldable support leg structure. At the same time, the threaded connection between the fasteners and the main body ensures the connection strength and facilitates disassembly and maintenance, meeting the dual requirements of support stability and portability for different usage scenarios.

[0023] In some embodiments, the first connecting part is a ferromagnetic metal component or a magnetic component, used for magnetically connecting with the support device, and the second connecting part is a ferromagnetic metal component or a magnetic component, used for magnetically connecting with the support device. By setting the first and second connecting parts as ferromagnetic metal components or magnetic components respectively, they can form a magnetic connection with the support device. The magnetic connection structure eliminates the need for a complex mechanical locking mechanism, facilitating quick assembly and disassembly between the buoyancy device and the support device, while avoiding corrosion problems that may occur with threaded connections, thus improving the durability of the device in humid environments. The ferromagnetic metal component may include at least one of iron, nickel, cobalt, steel, silicon steel, permalloy, and martensitic stainless steel.

[0024] In some embodiments, the first connecting part is a snap-fit ​​component for snapping into the support device, and the second connecting part is a snap-fit ​​component for snapping into the support device. By setting the first and second connecting parts as snap-fit ​​components, they can form a snap-fit ​​connection with the support device. This mechanical connection structure achieves quick locking and unlocking operations through precise snap-fit ​​engagement, ensuring the reliability of the connection between the buoyancy device and the support device, and facilitating user assembly and disassembly.

[0025] In some embodiments, the first connecting part is a stud or a threaded hole for threaded connection with the support device, and the second connecting part is a stud or a threaded hole for threaded connection with the support device. By setting the first and second connecting parts as studs or threaded holes respectively, they can form a threaded connection with the support device. This mechanical connection method generates a reliable axial preload through thread engagement, ensuring extremely high connection strength and stability between the buoyancy device and the support device. It can effectively resist vibration and impact loads generated during underwater operations and prevent the connection from loosening.

[0026] In some embodiments, the axial direction of the first connecting part is parallel to the axial direction of the buoyancy rod, and the axial direction of the second connecting part is parallel to the radial direction of the buoyancy rod. This specific structural configuration, with the first connecting part parallel to the axial direction of the buoyancy rod and the second connecting part parallel to the radial direction of the buoyancy rod, achieves multi-functional positioning of the shooting device. Users can choose to use the first connecting part for vertical fixation or the second connecting part for horizontal fixation according to actual shooting needs. Both connection methods can use the same support device. Without adding additional components, the multi-angle switching function of the shooting device is achieved simply by changing the connection direction, significantly improving the device's environmental adaptability and usage efficiency.

[0027] In some embodiments, the axial extension direction of the first connecting part is approximately perpendicular to the axial extension direction of the second connecting part. This orthogonal arrangement of the axial directions of the first and second connecting parts provides users with flexible options. Users can decide whether to use the first connecting part for vertical fixation or the second connecting part for horizontal fixation based on actual shooting needs. Both connection methods can use the same support device. Without adding additional components, the multi-angle switching function of the shooting device is achieved simply by changing the connection direction, significantly improving the environmental adaptability and usage efficiency of the device.

[0028] In some embodiments, the buoyancy device further includes a counterweight, which can be connected to the buoyancy device via the first connecting part. By adding a counterweight to the buoyancy device and achieving a detachable connection between the buoyancy device and the counterweight via the first connecting part, the overall buoyancy balance of the buoyancy device can be flexibly adjusted according to actual usage requirements. When the buoyancy device is connected to the counterweight via the first connecting part, the sinking force provided by the counterweight can offset part of the buoyancy of the buoyancy device, achieving neutral buoyancy adjustment or negative buoyancy state of the buoyancy device in water, facilitating depth control and attitude stability during underwater operations. The connection method between the first connecting part and the counterweight maintains the same interface standard as the support device, ensuring the convenience and reliability of counterweight installation. This design, through a modular counterweight connection scheme, enables the same buoyancy device to adapt to different water environments and working depth requirements, significantly improving the environmental adaptability and operational condition adjustment capability of the buoyancy device.

[0029] In some embodiments, the buoyancy device further includes a traction rope, which can be detachably connected to either the first or second connecting part. By adding a traction rope to the buoyancy device and enabling it to be selectively and detachably connected to either the first or second connecting part, not only is multi-directional traction control of the buoyancy device achieved, but reliable anti-loss protection is also provided. When the traction rope is connected to the first connecting part, traction force can be applied along the axial direction of the buoyancy bar, and the rope fixation effectively prevents the buoyancy device from accidentally falling off during vertical operations. When the traction rope is connected to the second connecting part, lateral traction force can be applied along the radial direction of the buoyancy bar, ensuring the connection reliability of the buoyancy device during lateral movement. This dual-mode traction connection method, through the standardized interface design of the first and second connecting parts, not only enables selective adjustment of the traction direction but also constructs a dual anti-loss protection mechanism, enabling the buoyancy device to maintain flexible maneuverability in complex underwater environments while effectively avoiding the risk of equipment loss due to connection failure, significantly improving operational safety and equipment recovery rate.

[0030] This application also provides a shooting system, which includes a buoyancy device as described in any of the above embodiments and a shooting device connected to the buoyancy device.

[0031] The aforementioned shooting system, because it includes the buoyancy device described in any of the above embodiments, also has at least the following beneficial effects: Its buoyancy device is configured with a main body detachably connected to the shooting device, and a first connecting part and a second connecting part are respectively provided on the first and second end faces of the main body, allowing both the first and second connecting parts to be detachably connected to the support device. When the first connecting part is connected to the support device, the shooting device can maintain a vertical orientation relative to the direction of gravity. For example, when placed vertically on land or underwater, the support device fixes the main body through the first connecting part, keeping the shooting device in an upright state for vertical perspective shooting. When the second connecting part is connected to the support device, the shooting device can maintain a horizontal orientation relative to the direction of gravity. For example, when placed horizontally on land or underwater, the support device fixes the main body through the second connecting part, keeping the shooting device in a horizontal state for level-view shooting. In other words, users can flexibly choose to connect either the first or second connecting part to the same support device according to their shooting needs, achieving flexible and convenient switching between vertical and horizontal shooting postures in different scenarios such as land and underwater.

[0041] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0042] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, this application provides a buoyancy device 10, which includes a main body 100, a first connecting portion 210, and a second connecting portion 220. The main body 100 can be detachably connected to a shooting device 20. The first connecting portion 210 is disposed on a first end face 101 of the main body 100, and the second connecting portion 220 is disposed on a second end face 102 of the main body 100. Both the first connecting portion 210 and the second connecting portion 220 are used for detachable connection with a support device 500. For example... Figure 1 As shown, when the first connecting part 210 is connected to the support device 500, the shooting device 20 is vertically positioned relative to the direction of gravity G; as Figure 2 As shown, when the second connecting part 220 is connected to the support device 500, the shooting device 20 is arranged laterally relative to the direction of gravity G.

[0043] The aforementioned buoyancy device 10 can achieve at least the following beneficial effects:

[0044] By providing a main body 100 for detachably connecting the shooting device 20, and by providing a first connecting portion 210 and a second connecting portion 220 on the first end face 101 and the second end face 102 of the main body 100 respectively, both the first connecting portion 210 and the second connecting portion 220 can be detachably connected to the support device 500. Figure 1As shown, when the first connecting part 210 is connected to the support device 500, the shooting device 20 can maintain a vertical orientation relative to the direction of gravity G. For example, when placed vertically on land or underwater, the support device 500 fixes the main body 100 through the first connecting part 210, allowing the shooting device 20 to maintain an upright state for vertical perspective shooting. Figure 2 As shown, when the second connecting part 220 is connected to the support device 500, the shooting device 20 can maintain a horizontal orientation relative to the direction of gravity G. For example, when placed horizontally on land or underwater, the support device 500 fixes the main body 100 through the second connecting part 220, keeping the shooting device 20 in a horizontal position for level shooting. In other words, users can flexibly choose to connect either the first connecting part 210 or the second connecting part 220 to the same support device 500 according to their own shooting needs, realizing flexible and convenient switching between vertical and horizontal shooting postures of the shooting device 20 in different scenarios such as land and underwater.

[0045] Understandably, when the first connecting part 210 is connected to the support device 500, the shooting device 20 is vertically positioned relative to the direction of gravity G. This can be considered as the axis of the main body 100 of the shooting device 20 being approximately parallel to the direction of gravity G, allowing for a certain degree of installation angle deviation. In this state, the shooting device 20 can perform vertical framing and shooting. When the second connecting part 220 is connected to the support device 500, the shooting device 20 is horizontally positioned relative to the direction of gravity G. At this time, the axis of the main body 100 of the shooting device 20 is approximately perpendicular to the direction of gravity G, allowing for a certain degree of angular deviation. In this state, the shooting device 20 can perform horizontal framing and shooting.

[0046] In some embodiments, the axial direction of the first connecting portion 210 is parallel to the axial direction of the buoyancy rod 110, and the axial direction of the second connecting portion 220 is parallel to the radial direction of the buoyancy rod 110. This specific structural configuration, with the first connecting portion 210 axially parallel to the buoyancy rod 110 and the second connecting portion 220 radially parallel to the buoyancy rod 110, achieves the multi-functional positioning capability of the shooting device 20. Users can choose to use the first connecting portion 210 for vertical fixation or the second connecting portion 220 for horizontal fixation according to actual shooting needs. Both connection methods can use the same support device 500. Without adding additional components, the multi-angle switching function of the shooting device 20 is achieved simply by changing the connection direction, significantly improving the device's environmental adaptability and usage efficiency.

[0047] In some embodiments, the axial extension direction of the first connecting portion 210 is approximately perpendicular to the axial extension direction of the second connecting portion 220. This orthogonal arrangement of the axial directions of the first connecting portion 210 and the second connecting portion 220 provides the user with flexible options. The user can decide to use the first connecting portion 210 for vertical fixation or the second connecting portion 220 for horizontal fixation according to actual shooting needs. Both connection methods can use the same support device 500. Without adding additional components, the multi-angle switching function of the shooting device 20 is achieved simply by changing the connection direction, significantly improving the environmental adaptability and usage efficiency of the device.

[0048] like Figure 4 As shown, in some embodiments, the main body 100 includes a hollow buoyancy rod 110 with an internal cavity and a mounting member 120. The mounting member 120 includes a mounting portion 121 for detachably connecting the shooting device 20 and a telescopic portion 122 connected to the mounting portion 121. The telescopic portion 122 is inserted into the cavity from one end of the buoyancy rod 110 along the axial direction of the buoyancy rod 110 and can extend and retract relative to the buoyancy rod 110. A first connecting portion 210 is provided at the other end of the buoyancy rod 110, and a second connecting portion 220 is provided at the mounting portion 121. By providing the first connecting portion 210 at the other end of the buoyancy rod 110 and the second connecting portion 220 at the mounting portion 121, the combined structure of the buoyancy rod 110 and the mounting member 120 can achieve both vertical fixation via the first connecting portion 210 and horizontal fixation via the second connecting portion 220, improving the installation flexibility of the shooting device 20 in both vertical and horizontal fixing methods and its adaptability to different scenarios. The telescopic part 122 can be inserted into the cavity from one end of the buoyancy rod 110 along the axial direction of the buoyancy rod 110 and extend and retract relative to the buoyancy rod 110. This not only enables flexible adjustment of the installation height of the shooting device 20, but also changes the volume of the inner cavity of the buoyancy rod 110 through the telescopic movement of the telescopic part 122, thereby precisely adjusting the overall buoyancy of the buoyancy rod 110.

[0049] In some embodiments, the telescopic part 122 is threadedly connected to the buoyancy rod 110 and can rotate under external force to extend or retract relative to the buoyancy rod 110. By setting the telescopic part 122 and the buoyancy rod 110 as a threaded connection structure, the structural compactness between the buoyancy rod 110 and the mounting part 120 is maintained, and the telescopic part 122 can achieve axial extension and retraction adjustment relative to the buoyancy rod 110 through rotational movement under external force. This threaded connection method can not only precisely control the extension and retraction of the telescopic part 122 and realize fine adjustment of the installation height of the shooting device 20, but also ensure the stability and reliability of the adjusted position through the self-locking characteristic of the thread.

[0050] like Figure 3 and Figure 4 As shown, in some embodiments, the second connecting portion 220 is radially disposed on the mounting portion 121 along the buoyancy bar 110. By disposing the second connecting portion 220 radially on the mounting portion 121 along the buoyancy bar 110, the second connecting portion 220 can directly provide a lateral fixing interface, thereby achieving stable horizontal fixing when the mounting portion 121 is connected to the imaging device 20. This radial arrangement not only optimizes the structural layout of the mounting portion 121, making the functional integration of the second connecting portion 220 and the mounting portion 121 more compact, but also complements the axial arrangement of the first connecting portion 210 along the end of the buoyancy bar 110, enabling the buoyancy device 10 to simultaneously meet the requirements of both vertical and lateral fixing methods.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments, the main body 100 further includes a fixing component 300 disposed on the mounting portion 121. The fixing component 300 is used to snap, magnetically connect, or thread-connect with the shooting device 20. By providing the fixing component 300 on the mounting portion 121, the shooting device 20 can be quickly fixed or disassembled with the mounting portion 121 by snap, magnetic, or thread connection, thereby significantly improving the convenience of installing and disassembling the shooting device 20. The diverse connection methods of the fixing component 300 can be flexibly selected according to different shooting needs, which not only ensures the reliability of the connection but also enhances the compatibility of the buoyancy device 10 with shooting devices 20 of different specifications, further expanding the adaptability of the application scenarios.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments, the fixing assembly 300 includes a knob 310 rotatably connected to the mounting portion 121 and a threaded connector 320 connected to the knob 310. The knob 310 is used to operate the threaded connector 320 to thread it onto the shooting device 20. The knob 310 is designed to be more user-friendly and easy to operate. The operator can rotate the knob 310 to drive the threaded connector 320 to form a threaded fastening with the shooting device 20. This mechanical linkage structure not only enables quick locking and unlocking of the shooting device 20, but also ensures the reliability of the fixing strength through the threaded connection.

[0053] like Figure 3 and Figure 4As shown, in some embodiments, the buoyancy device 10 further includes an anti-rotation fin 400. The anti-rotation fin 400 and the second connecting portion 220 are respectively disposed on both sides of the mounting portion 121. The anti-rotation fin 400 can move relative to the mounting portion 121 to a folded state and an unfolded state. In the unfolded state, the anti-rotation fin 400 can prevent the buoyancy rod 110 from rotating underwater due to water flow. The symmetrical arrangement of the anti-rotation fin 400 and the second connecting portion 220 on both sides of the mounting portion 121 optimizes the overall force balance, enabling the buoyancy device 10 to maintain precise control of the shooting angle even in complex water flow environments. The folded state of the anti-rotation fin 400 reduces the overall size of the buoyancy device 10, facilitating storage. In the unfolded state, the anti-rotation fin 400 effectively suppresses the rotation of the buoyancy rod 110 caused by water flow impact, ensuring the azimuth stability of the shooting device 20. The foldable design of the anti-rotation fin 400 not only keeps the device compact and easy to store when not in use, but also provides an anti-rotation effect when unfolded. Through simple mechanical action, it significantly improves underwater stability and optimizes shooting results.

[0054] like Figure 3 and Figure 4 As shown, in some embodiments, the anti-rotation fin 400 is rotatably connected to the mounting portion 121 and is rotatable relative to the mounting portion 121 to the folded state and the unfolded state. In the unfolded state, the length extension direction of the anti-rotation fin 400 is approximately parallel to the radial direction of the mounting portion 121. In the folded state, the length extension direction of the anti-rotation fin 400 is approximately parallel to the axial direction of the buoyancy rod 110. By rotatably connecting the anti-rotation fin 400 to the mounting part 121, the anti-rotation fin 400 can rotate relative to the mounting part 121 to a folded state and an unfolded state. In the unfolded state, the length extension direction of the anti-rotation fin 400 is approximately parallel to the radial direction of the mounting part 121. This can be considered a biomimetic design to function similarly to a fish fin, effectively suppressing the rotation of the buoyancy rod 110 caused by water flow underwater, ensuring the azimuth stability of the imaging device 20. In the folded state, the length extension direction of the anti-rotation fin 400 is approximately parallel to the axial direction of the buoyancy rod 110. If the anti-rotation fin 400 is folded into the outer circumference of the buoyancy rod 110, the overall size of the buoyancy device 10 is reduced, making it easier to store and carry. This rotatable connection structure achieves the switching of the anti-rotation fin 400 state through simple mechanical action, satisfying the underwater anti-rotation function requirements while also considering the portability and ease of operation of the device.

[0055] like Figure 2As shown, in some embodiments, the support device 500 is a tripod, or the support device 500 is a telescopic rod, wherein the telescopic rod includes a tripod. By setting the support device 500 as a tripod or a telescopic rod including a tripod, two different support structure options are provided. The tripod structure ensures stable planar support, while the telescopic rod structure combines height adjustment and support functions. The support device 500 and the main body 100 can be integrally fixed or detachably connected. Integral fixing ensures the overall structural robustness, while detachable connection facilitates disassembly, storage, carrying, transportation, and flexible replacement of different support devices 500 to meet the needs of different usage scenarios.

[0056] like Figure 5 and Figure 6 As shown, in some embodiments, the support device 500 includes a fastener 520 and at least three support legs 530. One of the at least three support legs 530 is provided with a support post 531, and the remaining at least three support legs 530 are rotatably fitted onto the support post 531 and can move to a folded position and an unfolded position. The fastener 520 is provided along the axial direction of the support post 531 at one end of the support post 531 and is used to drive the support post 531 to rotate, so that the support post 531 is threadedly connected to the body 100 of the buoyancy device 10. Figure 5 As shown, in the unfolded position, the at least three support legs 530 are circumferentially spaced along the support column 531 to provide support onto the plane. Figure 6 As shown, in the folded position, the at least three support legs 530 are stacked circumferentially along the support column 531. Fasteners 520 are axially arranged along the support column 531 and threadedly connected to the main body 100 of the buoyancy device 10, ensuring a stable connection between the support device 500 and the main body 100. The at least three support legs 530 can rotate relative to each other circumferentially along the support column 510 and can switch between the folded and unfolded positions. When unfolded, the at least three support legs 530 are spaced apart circumferentially along the support column 531 to form a stable planar support structure. When folded, the at least three support legs 530 are stacked circumferentially along the support column 531 to reduce space occupation. This structural design ensures the stability of the support device 500 in the unfolded state and achieves compact storage of the device through the foldable support legs 530 structure. Furthermore, the threaded connection between the fasteners 520 and the main body 100 ensures connection strength and facilitates disassembly and maintenance, meeting the dual requirements of support stability and portability for different usage scenarios.

[0057] like Figure 5 and Figure 6As shown, in some embodiments, the fastener 520 includes a knob portion 521 and a fastening portion 522. One end of the fastening portion 522 is connected to the knob portion 521, and the other end of the fastening portion 522 passes through the support column 531 along the axial direction of the support column 531 and is used for threaded connection with the body 100 of the buoyancy device 10. The knob portion 521 is used for operation to drive the rotation of the fastening portion 522.

[0058] In some embodiments, the first connecting part 210 is a ferromagnetic metal component or a magnetic component, used for magnetically connecting with the support device 500, and the second connecting part 220 is a ferromagnetic metal component or a magnetic component, used for magnetically connecting with the support device 500. By setting the first connecting part 210 and the second connecting part 220 as ferromagnetic metal components or magnetic components respectively, they can form a magnetic connection with the support device 500. The magnetic connection structure does not require a complex mechanical locking mechanism, which facilitates quick assembly and disassembly between the buoyancy device 10 and the support device 500, while avoiding the corrosion problems that may occur with threaded connections, and improving the durability of the device in humid environments. The ferromagnetic metal component may include at least one of iron, nickel, cobalt, steel, silicon steel, permalloy, and martensitic stainless steel.

[0059] In some embodiments, the first connecting part 210 is a snap-fit ​​component for snapping into the support device 500, and the second connecting part 220 is a snap-fit ​​component for snapping into the support device 500. By setting the first connecting part 210 and the second connecting part 220 as snap-fit ​​components, they can form a snap-fit ​​connection with the support device 500. This mechanical connection structure achieves quick locking and unlocking operations through precise snap-fit ​​engagement, ensuring the reliability of the connection between the buoyancy device 10 and the support device 500, and facilitating user assembly and disassembly.

[0060] In some embodiments, the first connecting portion 210 is a stud or a threaded hole for threaded connection with the support device 500, and the second connecting portion 220 is a stud or a threaded hole for threaded connection with the support device 500. By setting the first connecting portion 210 and the second connecting portion 220 as studs or threaded holes respectively, they can form a threaded connection with the support device 500. This mechanical connection method generates a reliable axial preload through thread engagement, ensuring extremely high connection strength and stability between the buoyancy device 10 and the support device 500. It can effectively resist vibration and impact loads generated during underwater operations and prevent the connection from loosening.

[0061] In some embodiments, the buoyancy device 10 further includes a counterweight (not shown), which can be connected to the buoyancy device 10 via the first connecting part 210. By adding a counterweight to the buoyancy device 10 and achieving a detachable connection between the buoyancy device 10 and the counterweight via the first connecting part 210, the overall buoyancy balance of the buoyancy device 10 can be flexibly adjusted according to actual usage requirements. When the buoyancy device 10 is connected to the counterweight via the first connecting part 210, the sinking force provided by the counterweight can offset part of the buoyancy of the buoyancy device 10, achieving neutral buoyancy adjustment or negative buoyancy state of the buoyancy device 10 in water, facilitating depth control and attitude stability during underwater operations. The connection method between the first connecting part 210 and the counterweight maintains the same interface standard as the support device 500, ensuring the convenience and reliability of counterweight installation. This design, through a modular counterweight connection scheme, enables the same buoyancy device 10 to adapt to different water environments and working depth requirements, significantly improving the environmental adaptability and working condition adjustment capability of the buoyancy device 10.

[0062] In some embodiments, the buoyancy device 10 further includes a traction rope (not shown) that can be detachably connected to the first connection portion 210 or the second connection portion 220. By adding a traction rope to the buoyancy device 10 and allowing it to be selectively and detachably connected to either the first connecting part 210 or the second connecting part 220, not only is multi-directional traction control of the buoyancy device 10 achieved, but reliable anti-loss protection is also provided. When the traction rope is connected to the first connecting part 210, traction force can be applied along the axial direction of the buoyancy bar 110, and the rope fixation effectively prevents the buoyancy device 10 from accidentally falling off during vertical operations. When the traction rope is connected to the second connecting part 220, lateral traction force can be applied along the radial direction of the buoyancy bar 110, ensuring the connection reliability of the buoyancy device 10 during lateral movement. This dual-mode traction connection method, through the standardized interface design of the first connecting part 210 and the second connecting part 220, not only allows for selective adjustment of the traction direction, but also constructs a dual anti-loss protection mechanism, enabling the buoyancy device 10 to maintain flexible maneuverability in complex underwater environments while effectively avoiding the risk of equipment loss due to connection failure, significantly improving operational safety and equipment recovery rate.

[0063] In addition, such as Figure 2 As shown, this application also provides a shooting system, which includes a buoyancy device 10 as described in any of the above embodiments and a shooting device 20 connected to the buoyancy device 10.

[0064] The above-described shooting system, because it includes the buoyancy device 10 described in any of the above embodiments, also has at least the following beneficial effects: its buoyancy device 10 is provided with a main body 100 that is detachably connected to the shooting device 20, and a first connecting portion 210 and a second connecting portion 220 are respectively provided on the first end face 101 and the second end face 102 of the main body 100, so that both the first connecting portion 210 and the second connecting portion 220 can be detachably connected to the support device 500. When the first connecting portion 210 is connected to the support device 500, the shooting device 20 can be kept vertically positioned relative to the direction of gravity G. For example, when it is placed vertically on the ground on land or underwater, the support device 500 fixes the main body 100 through the first connecting portion 210, so that the shooting device 20 is kept in a vertical position for vertical perspective shooting. When the second connecting part 220 is connected to the support device 500, the shooting device 20 can maintain a horizontal orientation relative to the direction of gravity G. For example, when placed horizontally on land or underwater, the support device 500 fixes the main body 100 through the second connecting part 220, keeping the shooting device 20 in a horizontal position for level shooting. In other words, users can flexibly choose to connect either the first connecting part 210 or the second connecting part 220 to the same support device 500 according to their own shooting needs, realizing flexible and convenient switching between vertical and horizontal shooting postures of the shooting device 20 in different scenarios such as land and underwater.
