Description

Technical Field

[0001] This invention relates to the field of marine environmental monitoring equipment technology, specifically to a marine surface drift monitoring device. Background Technology

[0002] The marine environment refers to the vast and continuous waters of the oceans and seas on Earth, including seawater, dissolved and suspended substances in seawater, seabed sediments, and marine life. It is the cradle of life and a treasure trove of resources for humankind. As the scale of human exploitation of marine resources has been expanding, the marine environment has been affected and polluted by human activities. Therefore, it is necessary to use marine environmental monitoring devices to understand the marine ecological environment.

[0003] During the patent application process, a search revealed a Chinese patent with patent number CN118464127A: an online automatic detection device for marine ecological environment monitoring, comprising a float assembly and functional components mounted on the float assembly. The float assembly includes a ring-shaped float unit, a protective cavity located at the lower end of the float unit, and a sealing plate rotatably mounted at the lower end of the protective cavity. The detection component is located inside the float unit and the protective cavity. The detection component opens the sealing plate and extends out of the protective cavity under the action of a telescopic unit. Several collection boxes are arranged around the float unit. A collection port is provided on the side of the collection box away from the float unit. A baffle is provided on the collection box at the position corresponding to the collection port. Multiple sets of pressure plates are arranged side by side on the upper part of the inside of the collection box. This invention avoids interference from floating objects or fish in the ocean during operation and can collect garbage floating on the sea surface.

[0004] However, while the above-mentioned solutions collect marine environmental data through detection components, they lack monitoring equipment for the ocean surface. Traditional ocean surface monitoring relies on cameras, but these cameras lack protective structures. Salt spray can easily corrode camera lenses and electronic components, significantly reducing image clarity and affecting the validity of monitoring data. Furthermore, most monitoring devices have fixed camera shooting angles or can only achieve limited and inflexible angle adjustments, making it difficult to comprehensively capture the distribution and migration information of drifting objects. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a marine surface drift monitoring device to achieve the above-mentioned objectives.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a marine surface drift monitoring device, comprising: a floating tube, a signal receiver fixedly connected to the upper end of the floating tube, two symmetrical cameras arranged at the upper end of the signal receiver, a protective component arranged on the outer side wall of the camera, an adjustment component for changing the camera angle arranged on the inner wall of the signal receiver, and a floating ring fixedly connected to the outer side wall of the floating tube. The protective assembly includes a transparent protective cover, with a fixed base fixedly connected to the opening of the transparent protective cover. An annular cavity is formed on the inner wall of the fixed base, and a ring is rotatably connected to the inner wall of the annular cavity. The inner wall of the ring has a toothed groove. An annular groove communicating with the annular cavity is formed on one side of the fixed base. An annular baffle is slidably connected to the inner wall of the annular groove. A guide block is fixedly connected to one side of the annular baffle, and an arc-shaped scraper is fixedly connected to one side of the guide block. A driving assembly is provided on the inner wall of the transparent protective cover.

[0007] Preferably, the adjustment assembly includes a housing fixedly connected to the upper end of the float tube, two drive wheels rotatably connected to the inner wall of the housing, a drive belt installed between the two drive wheels, an adjustment rod fixedly connected to one side of each of the two drive wheels, and a mounting base fixedly connected to the outer wall of one end of the adjustment rod through which a mounting base is fixedly connected, and one side of the mounting base is fixedly connected to two cameras respectively by bolts. Preferably, a motor is fixedly connected to the lower end of the housing, and the output end of the motor passes through the housing and is fixedly connected to one of the drive wheels.

[0008] Preferably, the driving assembly includes a driving housing fixedly connected to the inner wall of the fixed base, the inner wall of the driving housing being connected to an annular cavity, a second motor fixedly connected to one side of the driving housing, a gear rotatably connected to the inner wall of the driving housing, and the output end of the second motor being fixedly connected to the gear.

[0009] Preferably, the gear is located on the inner wall of the ring, and the gear is meshed with the tooth groove.

[0010] Preferably, a rotating rod is fixedly connected to the outer wall of the transparent protective cover, the arc-shaped scraper is adapted to the outer wall of the transparent protective cover, a cleaning brush is installed on the side of the arc-shaped scraper near the transparent protective cover, and the end of the arc-shaped scraper away from the guide block is rotatably connected to the rotating rod.

[0011] Preferably, the inner wall of the floating tube is equipped with a battery and a controller, and the controller is electrically connected to the battery, a signal receiver, a camera, motor one, and motor two. Preferably, the camera is mounted on one side of the mounting base, and the fixing seat is bolted to one side of the mounting base and fitted onto the outer wall of the camera.

[0012] Compared with existing technologies, this invention provides a marine surface drift monitoring device with the following advantages: First, it enables precise dynamic monitoring of the marine surface environment and long-term protection of core components. The device uses a high-definition camera to capture the distribution and movement trajectory of floating objects on the marine surface in real time, and simultaneously monitors dynamic information such as the hydrological environment and meteorological conditions of the surrounding sea area, providing comprehensive and intuitive image data support for marine environmental monitoring. Second, in response to the harsh marine environment characterized by high salt spray, high humidity, and numerous floating impacts, a dedicated protective cover is installed on the camera. This cover is made of a special material with high light transmittance and corrosion resistance, which not only effectively isolates the camera from the erosion of seawater salt spray, preventing problems such as camera lens aging and short circuits caused by salt spray adhesion, but also prevents the attachment and growth of marine organisms (such as shellfish and algae), preventing floating objects from directly impacting the camera body. This avoids multiple risks that could damage the camera at the source, significantly extending the camera's service life, reducing equipment maintenance frequency and operating costs, and ensuring the continuity and stability of monitoring work.

[0013] Secondly, it features a flexible and adjustable shooting angle function, significantly improving the adaptability of the device to various scenarios. The device is powered by a motor, which drives the active drive wheel to rotate. A high-efficiency, stable drive belt enables synchronous rotation of the active and driven drive wheels, which in turn drives the adjusting rod, mounting base, and camera linked to the drive wheels to complete synchronized turning movements. This adjustment structure is rationally designed and provides smooth transmission, allowing for multi-angle and precise adjustment of the shooting angles of the two cameras. It can flexibly adjust the shooting angle according to different monitoring needs (such as precise monitoring of nearshore shallow waters, large-scale scanning of open waters in the open ocean, and tracking and monitoring of specific floating objects), easily adapting to complex and ever-changing marine monitoring scenarios. This effectively expands the monitoring coverage, enhances the device's applicability and versatility, and solves the pain point of traditional monitoring devices having fixed angles and difficulty in adapting to diverse monitoring needs.

[0014] Thirdly, a highly efficient and comprehensive cleaning mechanism is constructed to ensure the continuous clarity of the camera's field of view. The device features a specially designed cleaning mechanism that uses a motor to drive gears for precise rotation. The meshing of the gears and the circular ring teeth drives an arc-shaped scraper to move smoothly along the inner wall of the transparent protective cover. The cleaning brush mounted on the arc-shaped scraper is made of flexible, wear-resistant material, allowing it to closely adhere to the surface of the protective cover and efficiently remove seawater stains, plankton, silt, and other obstructions. This cleaning mechanism is precise in transmission and reliable in operation, enabling comprehensive and thorough cleaning of the protective cover surface. It completely avoids problems such as obstructed camera view and monitoring failure caused by obstructions, ensuring that the camera maintains clear imaging in complex marine environments. This provides high-quality image data for subsequent floating object identification and data analysis, further improving the monitoring accuracy and reliability of the entire monitoring system.

[0017] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0018] Please see Figure 1-6 This invention provides a technical solution for a marine surface drift monitoring device: A marine surface drift monitoring device includes: a floating cylinder 1, a signal receiver 2 fixedly connected to the upper end of the floating cylinder 1, two symmetrical cameras 3 provided at the upper end of the signal receiver 2, and the cameras 3 are used in existing monitoring equipment and are existing technology, which will not be described further; a protective component 4 is provided on the outer wall of the camera 3; an adjustment component 5 for changing the camera angle of the camera 3 is provided on the inner wall of the signal receiver 2; and a floating ring 6 is fixedly connected to the outer wall of the floating cylinder 1. The protective component 4 includes a transparent protective cover 401. A fixing base 402 is fixedly connected to the opening of the transparent protective cover 401. An annular cavity 403 is formed on the inner wall of the fixing base 402. A ring 404 is rotatably connected to the inner wall of the annular cavity 403. A toothed groove 405 is formed on the inner wall of the ring 404. An annular groove 406 communicating with the annular cavity 403 is formed on one side of the fixing base 402. An annular baffle 407 is slidably connected to the inner wall of the annular groove 406. A guide block 408 is fixedly connected to one side of the annular baffle 407. An arc-shaped scraper 409 is fixedly connected to one side of the guide block 408. A driving component 7 is provided on the inner wall of the transparent protective cover 401. By protecting the camera 3 with the transparent protective cover 401 on the outer wall of the camera 3, the transparent protective cover 401 isolates the camera 3 from the risks of seawater salt spray corrosion, marine organism attachment, and impact from floating objects, extending the service life of the camera 3, while also ensuring clear shooting by the camera 3.

[0019] The adjustment assembly 5 includes a housing 501 fixedly connected to the upper end of the float 1. Two drive wheels 502 are rotatably connected to the inner wall of the housing 501, and a drive belt 503 is installed between the two drive wheels 502. The rotation angle of each drive wheel 502 is 180 degrees, and the two drive wheels 502 are connected via the drive belt 503. An adjustment rod 504 is fixedly connected to one side of each drive wheel 502. A mounting base 505 is fixedly connected to the outer wall of one end of the adjustment rod 504. One side of the mounting base 505 is fixedly connected to two cameras 3 by bolts. A motor 5011 drives one drive wheel 502 to rotate, and the drive wheel 502 drives the other drive wheel 502 to rotate via the drive belt 503. The synchronous rotation of the two drive wheels 502 drives the two adjustment rods 504 and the mounting base 505 to rotate, thereby adjusting the shooting angle of the two cameras 3.

[0020] A motor 5011 is fixedly connected to the lower end of the housing 501, and a protective shell is installed on the outer wall of the motor 5011 to protect it from seawater. Furthermore, the motor 5011 is a three-phase AC asynchronous motor capable of forward and reverse rotation. The output end of the motor 5011 passes through the housing 501 and is fixedly connected to one of the drive wheels 502. The motor 5011 drives the drive wheel 502 to rotate.

[0021] The drive assembly 7 includes a drive housing 701 fixedly connected to the inner wall of the fixed base 402. The inner wall of the drive housing 701 is connected to the annular cavity 403. A second motor 702 is fixedly connected to one side of the drive housing 701. A gear 703 is rotatably connected to the inner wall of the drive housing 701, and the output end of the second motor 702 is fixedly connected to the gear 703. The rotation of the gear 703 output by the second motor 702 drives the annular ring 404 to rotate.

[0022] Gear 703 is located on the inner wall of ring 404 and meshes with tooth groove 405. The rotation of gear 703 and its meshing with tooth groove 405 drive ring 404 to rotate along the inner wall of annular cavity 403.

[0023] A rotating rod 4011 is fixedly connected to the outer wall of the transparent protective cover 401. An arc-shaped scraper 409 is adapted to the outer wall of the transparent protective cover 401. A cleaning brush 4091 is installed on the side of the arc-shaped scraper 409 closest to the transparent protective cover 401. The end of the arc-shaped scraper 409 away from the guide block 408 is rotatably connected to the rotating rod 4011. The arc-shaped scraper 409 and the cleaning brush 4091 can effectively clean the salt frost or water stains and other obstructions on the surface of the transparent protective cover 401, ensuring a clear field of view for the camera 3 and avoiding monitoring failure due to obstruction of the field of view.

[0024] The inner wall of the floating tube 1 is equipped with a storage battery 101 and a controller 102. The controller 102 is electrically connected to the storage battery 101, the signal receiver 2, the camera 3, the first motor 5011, and the second motor 702. The storage battery 101 provides power to the device, and the controller 102 facilitates the operation of the device by the staff.

[0025] The camera 3 is mounted on one side of the mounting base 505, and the fixing bracket 402 is bolted to one side of the mounting base 505 and fitted onto the outer wall of the camera 3. The mounting base 505 fixes the camera 3, ensuring the stability of the camera 3 during the shooting process; the fixing bracket 402, together with the transparent protective cover 401, can protect the camera 3 without obstructing its field of view.

[0026] In practical use, this invention serves as a marine surface drift monitoring device. When deployed to the target monitoring area, the device utilizes a floating cylinder 1 and a floating ring 6 to provide buoyancy, enhancing its surface stability. Two cameras 3 monitor the surrounding waters, collecting image data such as the distribution of surface drift debris and changes in water color. During use, the cameras 3 are protected by a transparent protective cover 401 to prevent corrosion from seawater salt spray, attachment of marine organisms, and impact from floating debris. This protects the camera lenses from damage without affecting the field of view, ensuring clear image acquisition.

[0027] When the monitoring angle of camera 3 needs to be adjusted, the controller 102 drives motor 5011 to start. Motor 5011 drives one of the drive wheels 502 to rotate. Through the transmission action of drive belt 503, the other drive wheel 502 rotates synchronously. When the two drive wheels 502 rotate, they drive the adjusting rod 504 and the mounting base 505 to rotate synchronously, thereby adjusting the shooting angle of the two cameras 3 and improving the flexibility of monitoring.

[0028] When staff discover that salt frost, water stains, plankton, or other obstructions are attached to the surface of the transparent protective cover 401, affecting the clarity of the image captured by camera 3, controller 102 starts motor 702. Motor 702 outputs gear 703 to rotate, and gear 703 meshes with tooth groove 405 to drive the ring 404 to rotate along the annular cavity 403. When the ring 404 rotates, the annular baffle 407 rotates along the inner wall of the annular groove 406. The annular baffle 407 drives the guide block 408 to slide along the annular groove 406. The guide block 408 drives the arc-shaped scraper 409 to move and cooperate with the cleaning brush 4091 to scrape away the obstructions on the surface of the transparent protective cover 401, achieving thorough cleaning of the surface of the transparent protective cover 401. After cleaning, it is easier for camera 3 to capture clear images. In addition, all parts in this device are made of corrosion-resistant materials, and some parts are coated with anti-corrosion paint to extend the service life of the device.
