Description

Technical Field

[0001] This application relates to the field of offshore wind power construction technology, and in particular to reusable underwater camera devices and offshore jacket components. Background Technology

[0002] With the continuous development of the offshore wind power industry, jacket foundation structures are widely used in medium and deep water projects. This foundation is formed by welding steel pipes, and the bottom ends of the matching steel pipe piles are buried inside the seabed foundation. The bottom of the jacket is equipped with a conical or tubular tip. During construction, the jacket is lowered as a whole, and the tip is inserted into the cavity of the steel pipe pile to complete the assembly.

[0003] In the installation process of the jacket and steel pipe pile, in order to facilitate the observation of the connection status and control the assembly accuracy, a camera device is usually installed on the side wall at the bottom of the jacket to observe the relative position of the insertion tip and the steel pipe pile.

[0004] However, in actual underwater operations, the underwater working environment is complex, and there may be situations where the guide frame is misaligned and inserted into the steel pipe pile, which may cause the camera device to get stuck in the gap between the guide frame and the steel pipe pile, resulting in camera device jamming or damage. Summary of the Invention

[0005] Therefore, it is necessary to provide a recoverable underwater camera device and offshore jacket assembly to address the problem that when the jacket is inserted at an angle into the jacket assembly, the camera device gets stuck in the gap between the jacket and the steel pipe pile, causing the camera device to malfunction or be damaged.

[0006] On one hand, this application provides a recoverable underwater camera device, which includes:

[0007] A fixed base is set on the component to be inserted, which is used to connect to the underwater installation base;

[0008] The camera component is used to capture the connection between the connector to be plugged in and the mounting base, and to transmit the captured images to a remote terminal.

[0009] A locking assembly is disposed between the camera assembly and the fixed base. The locking assembly has a locked state that fixes the camera assembly to the fixed base and an unlocked state that separates the camera assembly from the fixed base.

[0010] The detector is connected in communication with the locking assembly. The detector is used to detect the impact acceleration of at least one of the fixed base, the camera assembly and the locking assembly. When the impact acceleration exceeds a preset value, the locking assembly switches to the unlocked state.

[0011] The rising component is fixed relative to the camera component. The rising component is configured such that when the locking component is in the unlocked state, it drives the camera component to float to the surface.

[0012] In one embodiment, the retrievable underwater camera device further includes a power supply assembly, and the locking assembly includes:

[0013] An electromagnetic adsorption component is provided on one of the mounting base and camera components. The electromagnetic adsorption component is electrically connected to the power supply component, which is used to supply power to the electromagnetic adsorption component.

[0014] A magnetic attachment is provided on another of the magnetic mounting base and camera assembly;

[0015] The electromagnetic adsorption component is configured such that when the power supply component supplies power to the electromagnetic adsorption component, the electromagnetic adsorption component and the magnetic adsorption component magnetically engage; when the power supply component stops supplying power to the electromagnetic adsorption component, the electromagnetic adsorption component and the magnetic adsorption component separate.

[0016] In one embodiment, the retrievable underwater camera device further includes:

[0017] An emergency unlocking component is disposed on at least one of the fixed base and the camera component, and the emergency unlocking component is drivenly connected to at least one of the electromagnetic adsorption component and the magnetic attraction component.

[0018] The emergency unlocking component is configured to drive the electromagnetic adsorption component and the magnetic attraction component to separate when the immersion depth of the retrievable underwater camera device exceeds a preset threshold.

[0019] In one embodiment, the emergency unlocking component is an electronically controlled emergency unlocking component.

[0020] In one embodiment, the retrievable underwater camera device further includes:

[0021] The water depth detection component is mounted on the camera component and is used to detect the water depth of the camera component. The water depth detection component is communicatively connected to the emergency unlocking component.

[0022] In one embodiment, the water depth detection component includes:

[0023] A water pressure sensor is mounted on the camera assembly and is used to detect water pressure data;

[0024] The conversion unit is used to receive water pressure data detected by the water pressure sensor and convert the water pressure data into water depth data.

[0025] In one embodiment, the retrievable underwater camera device further includes:

[0026] The power monitoring component communicates with the emergency unlocking component to monitor the remaining power of the emergency unlocking component;

[0027] The power supply component is communicatively connected to the power monitoring component and electrically connected to the emergency unlocking component;

[0028] When the power monitoring component detects that the remaining power of the emergency unlocking component is lower than the first preset power value, the power supply component supplies power to the emergency unlocking component.

[0029] In one embodiment, the retrievable underwater camera device further includes:

[0030] The mounting base is mounted on the camera assembly, and the locking assembly is located between the mounting base and the fixed base to lock or separate the mounting base and the fixed base.

[0031] In one embodiment, the rising component and the mounting base are relatively fixed and spaced apart, and the camera component is located between the rising component and the mounting base.

[0032] In one embodiment, along the distribution direction of the rising component and the mounting base, the projection of the camera component on the mounting base lies within the outline of the mounting base; and / or, the projection of the camera component on the rising component lies within the outline of the rising component.

[0033] In one embodiment, the rising component, the camera component, and the mounting base are distributed downwards in sequence along the direction of gravity.

[0034] In one embodiment, the retrievable underwater camera device further includes:

[0035] The buffer and anti-collision part covers at least a portion of the surface of the mounting base.

[0036] In one embodiment, the camera assembly is movably mounted on the mounting base to adjust the shooting angle, and the recoverable underwater camera device further includes:

[0037] The driver component is mounted on the mounting base and connected to the camera component driver to drive the camera component to move.

[0038] In one embodiment, the camera component includes:

[0039] Camera module;

[0040] The wireless transmission module communicates with the camera module and is used to wirelessly transmit images captured by the camera module to a remote terminal.

[0041] In one embodiment, the retrievable underwater camera device further includes:

[0042] The BeiDou satellite positioning module is installed on at least one of the ascending assembly and the camera assembly;

[0043] The wireless communication module is connected to the BeiDou satellite positioning module to receive the location information detected by the BeiDou satellite positioning module and wirelessly transmit it to the remote terminal.

[0044] On the other hand, this application provides a marine jacket assembly, which includes:

[0045] The main body of the jacket includes multiple interconnected insertion conduits, each with an insertion end for insertion and mating with a pipe pile in the seabed.

[0046] In any of the above embodiments, the retrievable underwater camera device has a fixed base mounted on the insertion conduit and close to the insertion end, and the camera component of the retrievable underwater camera device is used to capture the insertion of the insertion conduit and the pipe pile.

[0047] Using the technical solution of this application, a fixed base is installed on the end of the component to be inserted for insertion into the installation foundation, facilitating the recording of the insertion process between the component and the installation foundation. During the insertion process between the component and the underwater installation foundation, the component is mounted on a lowering device. The operator manipulates the lowering device to lower the component close to the installation foundation and align it for insertion. During this process, a camera component records the insertion process and transmits the images to a remote terminal for real-time observation by the operator. The operator adjusts the attitude of the lowering device based on the images displayed on the remote terminal to adjust the position of the component, thereby improving the success rate of insertion between the component and the installation foundation. If the component to be inserted is aligned directly with the mounting base, it will descend smoothly and maintain stable motion. If the component is not aligned, it will be inserted at an angle. Because the camera component is close to the end of the component intended for insertion, it may become stuck in the gap between the mounting base and the component. Adjusting the component's position, such as by pulling it out, could damage the camera component. If the component is not aligned, it will collide with the mounting base, generating a momentary impact force. This impact force is transmitted to the fixed base, causing the retrievable underwater camera to accelerate. When the detector detects that this acceleration exceeds a preset value, the locking mechanism switches to the unlocked state, the camera component separates from the fixed base, and rises under the drive of the rising mechanism for retrieval by the operator. This solution enables the camera component to separate from the fixed base in a timely manner when the component to be inserted is misaligned, and to float upward under the action of the lifting component, reducing the possibility of the camera component getting stuck or damaged.

[0061] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application 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 application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0062] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0063] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0064] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0065] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0066] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0067] See Figure 1A retrievable underwater camera device includes a fixed base 10, a camera assembly 30, a locking assembly 40, a detector, and a rising assembly 50. The system includes a fixed base 10 for mounting the component to be connected to an underwater installation base; a camera assembly 30 for capturing images of the connection between the component and the installation base and transmitting the captured images to a remote terminal 00; a locking assembly 40 positioned between the camera assembly 30 and the fixed base 10, having both a locked state (fixing the camera assembly 30 to the fixed base 10) and an unlocked state (separating the camera assembly 30 from the fixed base 10); a detector communicatively connected to the locking assembly 40, detecting the impact acceleration of at least one of the fixed base 10, the camera assembly 30, and the locking assembly 40; and switching the locking assembly 40 to the unlocked state when the impact acceleration exceeds a preset value; and a rising assembly 50 fixed relative to the camera assembly 30, configured to drive the camera assembly 30 to surface when the locking assembly 40 is in the unlocked state.

[0068] Using the technical solution of this application, the fixed base 10 is installed on the end of the component to be inserted for insertion into the installation foundation, so as to facilitate the recording of the insertion of the component into the installation foundation. During the insertion process of the component into the underwater installation foundation, the component is installed on the lowering device. The operator manipulates the lowering device to lower the component into a position close to the installation foundation and align it for insertion. During this process, the camera component 30 records the insertion of the component into the installation foundation and transmits the recorded images to the remote terminal 00 for real-time observation by the operator. The operator adjusts the posture of the lowering device based on the images displayed on the remote terminal 00 to adjust the position of the component to be inserted, thereby improving the success rate of insertion between the component and the installation foundation. If the component to be inserted is aligned directly with the mounting base, it will descend smoothly and maintain stable motion. If the component is not aligned directly with the mounting base, it will be inserted at an angle. Because the camera component is close to the end of the component to be inserted with the mounting base, the camera component 30 may get stuck in the gap between the mounting base and the component. When the position of the component is readjusted, such as when it is pulled out, the camera component 30 may be damaged. If the component is not aligned directly with the mounting base, it will collide with the mounting base and generate an instantaneous impact force. This impact force is transmitted to the fixed base 10, causing the retrievable underwater camera device to generate impact acceleration. When the detector detects that the impact acceleration exceeds a preset value, the locking component 40 switches to the unlocked state, the camera component 30 separates from the fixed base 10, and the camera component 30 floats up under the drive of the rising component 50 for the operator to retrieve. This solution enables the camera assembly 30 to separate from the fixed base 10 in a timely manner when the component to be inserted is misaligned, and to float upward under the action of the rising component 50, thereby reducing the possibility of the camera assembly 30 getting stuck or damaged.

[0069] It should be noted that the reusable underwater camera device in this solution can be installed in various underwater splicing operation scenarios, and is especially suitable for the installation of large marine structures such as offshore jacket components and offshore photovoltaic supports.

[0070] See Figure 2 In some embodiments, the retrievable underwater camera device of this solution is installed in a seabed jacket assembly. Exemplarily, the jacket assembly includes a jacket body, which includes multiple interconnected insertion conduits 01. Each insertion conduit 01 has an insertion end 011 for insertion into a corresponding seabed pile 02. A retrievable underwater camera device is mounted on each insertion conduit 01, and a mounting base 10 for the retrievable underwater camera device is fixedly mounted on the corresponding insertion conduit 01 and close to the insertion end 011. It should be noted that the insertion end 011 refers to the portion of the insertion conduit 01 that extends entirely into the seabed pile 02 after insertion. Figure 2 The diagram shows the insertion of the conduit 01 and the pipe pile 02 directly opposite each other.

[0071] In some embodiments, the retrievable underwater camera device further includes a power supply assembly 70, and a locking assembly 40 including an electromagnetic adsorption component 41 and a magnetic attraction component 42. The electromagnetic adsorption component 41 is disposed on one of the fixed base 10 and the camera assembly 30, and is electrically connected to the power supply assembly 70, which supplies power to the electromagnetic adsorption component 41. The magnetic attraction component 42 is disposed on the other of the fixed base 10 and the camera assembly 30. The electromagnetic adsorption component 41 is configured such that when the power supply assembly 70 supplies power to the electromagnetic adsorption component 41, the electromagnetic adsorption component 41 magnetically engages with the magnetic attraction component 42; when the power supply assembly 70 stops supplying power to the electromagnetic adsorption component 41, the electromagnetic adsorption component 41 separates from the magnetic attraction component 42. It should be noted that this solution remotely controls the power supply status of the power supply component 70. When the image captured by the camera component 30 shows that the connector to be inserted is in place, the operator cuts off the power supply to the power supply component 70. The electromagnetic adsorption component 41 loses its magnetism, and the camera component 30 separates from the fixed base 10. The rising component 50 then drives the camera component 30 to float upwards for the operator to retrieve. The design of the electromagnetic adsorption component 41 and the magnetic coupling component 42 results in a simple structure that facilitates remote operation.

[0072] In some embodiments, the electromagnetic adsorption component 41 and the power supply component 70 are both directly or indirectly disposed on the camera component 30. This arrangement facilitates the upward retrieval of the electromagnetic adsorption component 41 and the power supply component 70 along with the camera component 30, thereby simplifying maintenance of the electromagnetic adsorption component 41 and the power supply component 70.

[0073] In some embodiments, the retrievable underwater camera device further includes an emergency unlocking component, which is disposed on at least one of the fixed base 10 and the camera component 30, and is drivenly connected to at least one of the electromagnetic adsorption component 41 and the magnetic coupling component 42. The emergency unlocking component is configured to drive the electromagnetic adsorption component 41 and the magnetic coupling component 42 to separate when the water depth of the retrievable underwater camera device exceeds a preset threshold. In actual insertion process, especially for components to be inserted into marine structures, there are usually multiple interconnected components, and most of them are steel pipe structures. Typically, the operator lowers multiple components simultaneously using a lowering device, adjusts the position of the components, and ensures that each component is facing its corresponding mounting base, and then continues to lower multiple components simultaneously. During this process, some components may be located to the side of their corresponding mounting base due to ocean current disturbance or positioning error, i.e., they are not inserted into their corresponding mounting base. After the remaining connectors are inserted into their corresponding mounting bases, the unconnected connectors may fall beyond their preset mounting positions. In this case, the equipment needs to be lowered to lift multiple connectors upwards and reposition them. For connectors not connected to the mounting base, the camera assembly 30 on top of it may collide with the mounting base during its upward movement. To reduce the risk of collision between the camera assembly 30 and the mounting base during the upward movement, the emergency unlocking component disconnects the connection between the electromagnetic adsorption component 41 and the magnetic attraction component 42, allowing the camera assembly 30 to float upwards under the action of the lifting component 50 for the operator to retrieve.

[0074] In some embodiments, the emergency unlocking component is an electrically controlled emergency unlocking component. Making the emergency unlocking component electrically controlled allows for convenient remote control by operators.

[0075] In some embodiments, the retrievable underwater camera device further includes a depth detection component, which is mounted on the camera component 30 and used to detect the immersion depth of the camera component 30. The depth detection component is communicatively connected to the emergency unlocking component. It should be noted that there is a preset distance between the camera component 30 and the insertion end of the component to be inserted. The depth detection component detects the immersion depth of the camera component 30 and, based on the preset distance between the camera component 30 and the insertion end of the component to be inserted, confirms whether the immersion depth of the component to be inserted exceeds a preset threshold. Mounting the depth detection component on the camera component 30 facilitates synchronous movement of the depth detection component with the camera component 30, enabling real-time detection of the depth of the camera component 30 in the water, and also facilitating maintenance of the depth detection component.

[0076] In some embodiments, the depth detection component includes a depth sensor mounted on the camera assembly 30. This configuration results in a simple structure.

[0077] In some embodiments, the water depth detection component includes a water pressure sensor 60 and a conversion unit. The water pressure sensor 60 is mounted on the camera component 30 and is used to detect water pressure data. The conversion unit receives the water pressure data detected by the water pressure sensor 60 and converts the water pressure data into water depth data. Indirectly converting water pressure detected by the water pressure sensor 60 into water depth data provides higher accuracy and stronger anti-interference capabilities compared to detecting water depth data solely through a water depth sensor.

[0078] In some embodiments, the retrievable underwater camera device further includes a power monitoring component, which is communicatively connected to the emergency unlocking component to monitor its remaining power. A power supply component 70 is communicatively connected to the power monitoring component and electrically connected to the emergency unlocking component. When the power monitoring component detects that the remaining power of the emergency unlocking component is lower than a first preset power value, the power supply component 70 supplies power to the emergency unlocking component. By configuring the power monitoring component and the power supply component 70, the power of the emergency unlocking component can be replenished in a timely manner, improving its reliability.

[0079] In some embodiments, the recyclable underwater camera device further includes a mounting base 20, a camera assembly 30 disposed on the mounting base 20, and a locking assembly 40 disposed between the mounting base 20 and the fixed base 10, so as to lock or separate the mounting base 20 and the fixed base 10, thereby achieving the locking or separation of the camera assembly 30 and the fixed base 10.

[0080] In some embodiments, the rising component 50 and the mounting base 20 are relatively fixed and spaced apart, and the camera component 30 is located between the rising component 50 and the mounting base 20. Positioning the camera component 30 between the rising component 50 and the mounting base 20, rather than at the end of the overall device, allows the rising component 50 and the mounting base 20 to protect the camera component 30 after it is tilted during insertion or interferes with or collides with other components, reducing the risk of the camera component 30 being bumped or knocked.

[0081] In some embodiments, along the distribution direction of the rising component 50 and the mounting base 20, the projection of the camera component 30 onto the mounting base 20 lies within the outline of the mounting base 20; and / or, the projection of the camera component 30 onto the rising component 50 lies within the outline of the rising component 50. This arrangement further enhances the protective effect of the rising component 50 and the mounting base 20 on the camera component 30, and further reduces the possibility of interference or collision between the camera component 30 and other components.

[0082] In some embodiments, the lifting component 50, camera component 30, and mounting base 20 are arranged sequentially downwards along the direction of gravity. This arrangement positions the lifting component 50 above the camera component 30 and the mounting base 20 below it. When the connector is inserted into the mounting base along the direction of gravity, the lifting component 50 and mounting base 20 better protect the camera component 30, reducing the likelihood of collisions between the camera component 30 and other components. Even if the connector tilts, the lifting component 50 and mounting base 20 are more likely to make contact with the mounting base before the camera component 30, further enhancing the protection of the camera component 30. Furthermore, the lifting component 50's superior position helps ensure that the device's center of buoyancy is higher than its center of gravity, reducing the likelihood of tipping or tilting during ascent and improving stability.

[0083] In some embodiments, the rising assembly 50 includes a buoyancy pontoon 51 and a protective shell 52 that are sequentially fitted together from the inside to the outside. The buoyancy pontoon 51 is filled with a composite buoyancy material 53 in the form of closed-cell foam to enhance the buoyancy effect. The protective shell 52 is made of high-density polyethylene material to enhance the impact protection effect.

[0084] In some embodiments, the device further includes an explosion-proof chamber 21, which is sealed at the end of the mounting base 20 away from the fixed base 10 and spaced apart from the camera assembly 30. The power supply assembly 70 is disposed inside the explosion-proof chamber 21, and the lifting assembly 50 is disposed at the end of the explosion-proof chamber 21 away from the mounting base 20. The explosion-proof chamber 21 is designed to protect the power supply assembly 70.

[0085] In some embodiments, the retrievable underwater camera device further includes a buffer anti-collision part 80, which covers at least a portion of the surface of the mounting base 20. During the insertion of the connector, it is prone to collision with the mounting base. The impact force generated by the collision is transmitted to the fixed base 10 and the mounting base 20, and then through the mounting base 20 to the components mounted thereon. Alternatively, during the insertion of the connector, the fixed base 10 and the mounting base 20 may collide with the mounting base, and the impact force is transmitted or acts on the mounting base 20, and then through the mounting base 20 to the components mounted thereon. After the impact force is transmitted to the components mounted on the mounting base 20, the components may become loose or damaged, affecting their normal operation. The buffer anti-collision part 80 can absorb the impact force and reduce the transmission of the impact force to the components mounted on the mounting base 20.

[0086] In some embodiments, the mounting base 20 includes a first end face and a second end face disposed opposite each other along the direction of gravity, and the electromagnetic adsorption member 41 is disposed on the first end face of the mounting base 20. The mounting base 20 also includes a first peripheral surface connecting the first end face and the second end face, and a buffer anti-collision part 80 covers the second end face and the first peripheral surface. This arrangement can improve the protection and buffering effect of the buffer anti-collision part 80 on the entire mounting base 20.

[0087] In some embodiments, the buffer anti-collision part 80 includes an anti-collision guard plate 81, which is annularly disposed on the first circumferential surface and is made of high manganese steel. By providing the anti-collision guard plate 81 made of high manganese steel on the first circumferential surface of the mounting base 20, the anti-collision effect is improved. The buffer anti-collision part 80 also includes a buffer pad 82, which is disposed on the second end face of the mounting base 20 and is used to contact the components mounted on the mounting base 20, thereby facilitating the buffering of impact forces.

[0088] In some embodiments, the camera component 30 is movably mounted on the mounting base 20 to adjust the shooting angle. The recoverable underwater camera device also includes a drive component, which is mounted on the mounting base 20 and drivenly connected to the camera component 30 to drive the camera component 30 to move. For example, the drive component is electrically controlled and can be remotely operated; that is, this solution remotely controls the driving action of the drive component, offering high ease of operation.

[0089] In some embodiments, the retrievable underwater camera device further includes a gimbal assembly 31, which comprises a gimbal base, a first rotating frame, and a second rotating frame. The gimbal base is fixed to the mounting base 20, and a buffer pad 82 is located between the gimbal base and the second end face of the mounting base 20. The first rotating frame is rotatably disposed relative to the gimbal base about a first direction, and the second rotating frame is rotatably disposed relative to the first rotating frame about a second direction. The first and second directions have an included angle. Preferably, the first direction is the direction of gravity, and the second direction is the horizontal direction. This arrangement facilitates adjustment of the shooting angle of the camera assembly 30 and increases the shooting range of the camera assembly 30.

[0090] In some embodiments, the gimbal base, the first rotating frame, and the second rotating frame are all housed inside the explosion-proof chamber 21 to facilitate protection of each component.

[0091] In some embodiments, the camera assembly 30 includes a camera module and a wireless transmission module; the wireless transmission module is communicatively connected to the camera module and is used to wirelessly transmit images captured by the camera module to a remote terminal 00. Transmitting captured images wirelessly eliminates the need for transmission cables as in traditional solutions, reducing the complexity of the equipment. For example, the wireless transmission module uses an underwater acoustic communication unit, including an underwater acoustic modem and an underwater acoustic transducer, achieving a communication distance of up to 500m, enabling real-time wireless transmission of underwater high-definition video and control commands.

[0092] In some of these examples, the power monitoring component is also communicatively connected to the camera component 30 to monitor the remaining power of the camera component 30; the power supply component 70 is communicatively connected to the power monitoring component and electrically connected to the camera component 30; when the power monitoring component detects that the remaining power of the camera component 30 is lower than a second preset power value, the power supply component 70 supplies power to the camera component 30.

[0093] In some embodiments, the device further includes a supplementary lighting element disposed on the camera assembly 30 for supplementing the lighting of the camera assembly 30 to improve the clarity of the images captured by the camera assembly 30.

[0094] In some embodiments, the retrievable underwater camera device further includes a BeiDou satellite positioning module 501 and a wireless communication module. The BeiDou satellite positioning module 501 is disposed on at least one of the ascending component 50 and the camera component 30. The wireless communication module is communicatively connected to the BeiDou satellite positioning module 501 to receive the location information detected by the BeiDou satellite positioning module and wirelessly transmit it to the remote terminal 00. Through the cooperation of the BeiDou satellite positioning module 501 and the wireless communication module, the real-time location of the device can be easily transmitted to the remote terminal 00, facilitating personnel to track the location of the camera component 30 and thus facilitating its recovery.

[0095] Preferably, the BeiDou satellite positioning module 501 is located at the end of the ascending component 50 away from the camera component 30. This arrangement facilitates the surface emergence of the BeiDou satellite positioning module 501 after the device rises, enabling the detection of position signals.

[0096] It should be noted that in this solution, various wireless signals are transmitted to the remote terminal 00 via a surface relay network 000. Furthermore, the remote terminal 00 includes a display terminal for viewing images captured by the camera component 30; it also includes a data processing unit and a control component to enable data processing and the issuance of various commands via the remote terminal 00.

[0097] On the other hand, this application provides a marine jacket assembly, which includes a jacket body and a recoverable underwater camera device according to any of the above embodiments. The jacket body includes a plurality of interconnected insertion tubes 01, each insertion tube 01 having an insertion end 011 for insertion and engagement with a pipe pile 02 in the seabed, and the insertion end 011 is in the form of a pointed tip. The fixed base 10 of the recoverable underwater camera device is disposed on the insertion tube 01 and close to the insertion end 011, and the camera component 30 of the recoverable underwater camera device is used to capture the insertion of the insertion tube 01 and the pipe pile 02.

[0098] In some embodiments, at least two of the multiple insertion conduits 01 have misaligned end faces at their insertion ends 011. In this case, it is more likely that during the insertion process, some insertion conduits 01 will be inserted into the corresponding pipe pile 02, while others will not; it is also more likely that some insertion conduits 01 will be inserted at an angle. A retrievable underwater camera device allows for easier observation of the insertion status of the multiple insertion conduits 01.

[0099] In some embodiments, a mounting platform 012 is provided on the insertion conduit 01, and the mounting platform 012 is close to the insertion end 011 of the insertion conduit 01. The fixing base 10 is located at the periphery of the mounting platform 012 away from the insertion conduit 01. That is, the fixing base 10 is eccentrically positioned relative to the insertion conduit 01. This arrangement facilitates the camera assembly 30 in capturing images of the insertion status of the insertion conduit 01.

[0100] In some examples, the mounting platform 012 is arranged in a ring around the insertion conduit 01. The insertion conduit 01 is also equipped with reinforcing anti-collision plates 013, which are connected at the connection point between the insertion conduit 01 and the mounting platform 012. Multiple reinforcing anti-collision plates 013 are distributed circumferentially at intervals along the insertion conduit 01. The fixing base 10 is located between two adjacent reinforcing anti-collision plates 013 and close to one of them. Furthermore, in the horizontal direction, the projection of the recoverable underwater camera device lies within the outline of the adjacent reinforcing anti-collision plate 013. This arrangement further reduces the likelihood of collisions with the recoverable underwater anti-collision camera device.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
