[0002] As vital water transport vehicles, the structural integrity and safety of ships are of paramount importance. The coating of the ship's internal compartments plays an indispensable role, protecting the hull from corrosion by seawater, moisture, and cargo, extending the ship's service life, and crucially ensuring the stability of the ship's internal structure and the quality and safety of cargo. However, due to the complex and harsh marine environment in which ships operate for extended periods, the coating of the internal compartments faces severe challenges and is highly susceptible to corrosion, peeling, and other damage.

[0003] Traditional methods for inspecting coatings in ship interiors have numerous drawbacks. Manual visual inspection relies heavily on the experience and subjective judgment of the inspectors. In the complex spatial structure of ship interiors and under dim, humid conditions, the inspection efficiency is extremely low, and it is difficult to detect coating defects in hidden areas, leading to frequent missed inspections. While physical and chemical testing technologies such as ultrasound and X-rays can detect parameters such as coating thickness to some extent, the operational procedures are complex, requiring specialized technicians to perform complex equipment adjustments and operations. This not only significantly disrupts the normal operation of the ship's interiors but also incurs high inspection costs. Furthermore, these traditional methods often fail to obtain timely and comprehensive information on the overall condition of the coating, making it difficult to meet the demands of efficient and safe operation of modern ships.

[0025] Please see Figure 1-2 This utility model provides a ship interior coating status monitoring device, which includes: an inverted stabilizing bracket disposed on the top of the ship interior 7, with a monitoring hole 8 opened on the top of the ship interior 7, and the inverted stabilizing bracket passing through the monitoring hole 8; a pixel acquisition device disposed at the end of the inverted stabilizing bracket located inside the ship interior 7, for acquiring pixel information of the ship interior 7; a communication cable connected to the pixel acquisition device, the communication cable being connected to a host computer through the inverted stabilizing bracket for transmitting the pixel information; and a host computer for generating coating status monitoring information based on the pixel information.

[0026] In one possible embodiment, a monitoring hole 8 is opened at the top of the ship's interior 7, and an inverted stabilizing bracket is installed through the monitoring hole 8. A pixel acquisition device is fixed to the end of the inverted stabilizing bracket located inside the ship's interior 7, and a communication cable is connected, with one end connected to the pixel acquisition device and the other end connected to a host computer via the inverted stabilizing bracket. After the device is activated, it begins to collect pixel information from the ship's interior 7. The collected information is transmitted to the host computer via the communication cable. The host computer analyzes and processes the received pixel information to generate coating status monitoring information for staff to view and make decisions.

[0027] By collecting 7-pixel information of the ship's interior through a pixel acquisition device and transmitting it to a host computer via a communication cable to generate coating status monitoring information, it is possible to achieve automated and efficient detection, which is not affected by too much human subjective factors. It can timely and comprehensively grasp the coating status, reduce missed detections, and lower detection costs, which is of great significance for ensuring the structural integrity and safety of ships.

[0028] The existing installation and fixing methods of the detection devices are not stable enough. Under the conditions of vibration and swaying generated by the operation of the ship, the position of the detection devices may be displaced, affecting the accuracy of the detection, or even damaging the detection devices.

[0029] In this embodiment of the utility model, the inverted stabilizing bracket includes: an inverted multi-leg bracket, including multiple legs 1 and a top fixing plate 2, one end of the multiple legs 1 is evenly distributed around the periphery of the monitoring hole 8, and the other end is connected to the corresponding edge fixing point of the top fixing plate 2, the center of the top fixing plate 2 is coaxial with the center of the monitoring hole 8; and a telescopic rod 3, the top end of which is fixedly connected to the bottom center of the top fixing plate 2.

[0030] In one possible embodiment, when installing the inverted stabilizing bracket, first fix one end of each of the multiple legs 1 of the inverted multi-leg bracket around the perimeter of the monitoring hole 8, ensuring that the legs 1 are evenly distributed. Then, connect the top fixing plate 2 to the corresponding edge fixing points of the other end of the legs 1, ensuring that the center of the top fixing plate 2 is coaxial with the center of the monitoring hole 8. Finally, firmly fix the top end of the telescopic rod 3 to the bottom center of the top fixing plate 2 to complete the installation of the inverted stabilizing bracket.

[0031] The inverted multi-legged support and telescopic rod 3 design of the inverted stabilizing bracket feature multiple legs 1 evenly distributed around the monitoring port 8 and connected to the top fixing plate 2, making the bracket installation more stable and effectively resisting the swaying of the ship during operation. The telescopic rod 3 can flexibly adjust the height of the detection device to adapt to different cabin spaces and detection needs.

[0032] Traditional telescopic masts may have problems with insufficient strength and excessive weight. Insufficient strength can easily lead to deformation or even breakage of the telescopic mast during use, affecting the inspection work; excessive weight increases the difficulty of installation and may put additional burden on the structure of the ship's interior.

[0033] In this embodiment of the utility model, the telescopic rod 3 is made of high-strength lightweight carbon fiber, and its telescopic range is 0-15m.

[0034] In one possible embodiment, the high-strength lightweight carbon fiber can be T800 grade carbon fiber (PAN-based high-strength type) or T800 grade carbon fiber (PAN-based high-strength type).

[0035] The telescopic rod 3, made of high-strength and lightweight carbon fiber, is strong enough to ensure stable use in complex ship environments and is not easily deformed or broken. It is also lightweight, making it easy to install and operate, reducing the impact on the structure of the ship's interior. Its telescopic range of 0-15m can meet the inspection needs of different ship interior heights.

[0036] The surface of the ordinary telescopic mast 3 is not specially protected. In the corrosive environment of seawater and moisture in the ship's interior 7, it is easily corroded, which shortens its service life. Frequent friction will also damage the surface of the telescopic mast 3, affecting its performance and appearance. Furthermore, a single anti-corrosion coating is insufficient to meet the complex corrosive environment of the ship's interior 7, and its protective effect is limited. The coating is easily corroded and penetrated, resulting in damage to the telescopic mast 3.

[0037] In this embodiment of the utility model, the surface of the telescopic rod 3 is covered with an anti-corrosion layer and a wear-resistant layer from the inside out.

[0038] By covering the surface of the telescopic pole 3 with an anti-corrosion layer and a wear-resistant layer, it can effectively resist the corrosion of seawater, moisture and other substances, extend the service life of the telescopic pole 3, and the wear-resistant layer can also reduce surface damage caused by friction, ensuring the normal extension and contraction and stable operation of the telescopic pole 3.

[0039] In this embodiment of the invention, the anti-corrosion layer is a composite coating, which includes a bottom zinc-aluminum-magnesium alloy plating, an intermediate epoxy glass flake coating, and a surface fluorocarbon coating; the wear-resistant layer is a plasma spray coating.

[0040] In one possible embodiment, an anti-corrosion layer is first applied to the surface of the fabricated carbon fiber telescopic rod 3. The layers are applied sequentially: a bottom zinc-aluminum-magnesium alloy coating, an intermediate epoxy glass flake coating, and a surface fluorocarbon coating. The epoxy glass flake coating comprises epoxy resin and 20-30% glass flakes with a thickness of 200-500 μm. Each coating layer must be thoroughly dried and cured after application. After the anti-corrosion layer is applied, a wear-resistant layer is created on the surface using plasma spraying technology, ensuring uniform coverage. The wear-resistant layer can be made of Al2O3-TiO2.

[0041] The zinc-aluminum-magnesium alloy coating in the composite anti-corrosion layer provides basic electrochemical protection and has self-healing capabilities, capable of repairing coating defects caused by magnesium hydrolysis products. Its salt spray resistance exceeds 3,000 hours, and its resistance to oil penetration is 50% higher than traditional zinc plating. The parallel arrangement of glass flakes in the epoxy glass flake coating extends the penetration path of corrosive media, thus providing excellent shielding performance and preventing corrosive media intrusion. The fluorocarbon coating exhibits excellent weather resistance and chemical stability, further enhancing anti-corrosion capabilities. The plasma-sprayed coating, as a wear-resistant layer, has high hardness and good wear resistance, effectively protecting the surface of the telescopic rod.

[0042] Traditional inspection devices have limited shooting angles and ranges, making it difficult to comprehensively photograph the coating condition of every corner of the ship's interior, which can easily lead to omissions of some areas and incomplete inspection results.

[0043] In this embodiment of the utility model, the pixel acquisition device includes: a rotating device, fixedly disposed at the bottom end of the telescopic rod 3, the rotation angle range of the rotating device being ±90 degrees; an industrial line scan camera 4, fixedly connected to the rotating device; and a wide-angle lens, disposed at the lens position of the industrial line scan camera 4, the field of view of the wide-angle lens being 60 degrees.

[0044] In one possible embodiment, the fixed frame 6 of the rotating device is securely mounted on the bottom end of the telescopic rod 3, and the servo motor 5 is fixedly connected to the fixed frame 6. The industrial line scan camera 4 is then connected to the servo motor 5, ensuring a stable connection. Finally, the wide-angle lens is mounted at the lens position of the industrial line scan camera 4, and the lens focal length and other parameters are adjusted. After the device is turned on, the servo motor 5 drives the industrial line scan camera 4 to rotate, and pixel information is acquired in conjunction with the wide-angle lens.

[0045] The rotating device of the pixel acquisition unit allows the industrial line scan camera 4 to rotate ±90 degrees, expanding the shooting angle; the wide-angle lens has a field of view of 60 degrees, increasing the shooting range and enabling more comprehensive acquisition of pixel information of the coating of the ship's interior 7, thus improving the accuracy and completeness of the inspection.

[0046] In this embodiment of the utility model, the rotating device includes a servo motor 5 and a fixed frame 6. The fixed frame 6 is fixedly disposed at the bottom end of the telescopic rod 3. The servo motor 5 is fixedly connected to the fixed frame 6 and the servo motor 5 is connected to the industrial line scan camera 4.

[0047] In one possible embodiment, when installing the rotating device, the fixed frame 6 is first securely fixed to the bottom end of the telescopic rod 3 by welding or bolting. Then, the servo motor 5 is installed on the fixed frame 6, ensuring accurate positioning and a tight connection. Finally, the industrial line scan camera 4 is connected to the output shaft of the servo motor 5, and the connection position is adjusted to ensure that the camera does not experience eccentricity or other problems during rotation.

[0048] The rotating device, consisting of a servo motor 5 and a fixed frame 6, provides high control precision and can stably drive the industrial line scan camera 4 to rotate, ensuring that the camera remains stable during rotation and captures clear images, providing reliable data for accurate analysis of coating conditions.

[0049] In this embodiment of the invention, the industrial line scan camera 4 has a resolution of 3-5 megapixels.

[0050] By selecting an industrial line scan camera with 3-5 megapixels, the high resolution of the image allows for clear visualization of coating details, facilitating the observation of minute defects such as corrosion and peeling, thus improving the accuracy and reliability of the inspection.

[0051] In this embodiment of the utility model, the telescopic rod 3 is provided with a central conduit, and the communication cable passes through the central conduit through the telescopic rod 3 to connect with the host computer.

[0052] In one possible embodiment, a central conduit is reserved when manufacturing the telescopic pole 3. When installing the communication cable, one end of the cable is connected to the pixel acquisition device, then the cable is passed through the central conduit from one end of the telescopic pole 3 and out from the other end, and finally connected to the host computer, ensuring that the cable connection is firm and there is no looseness.

[0053] The communication cable is connected to the host computer through a central conduit inside the telescopic rod 3. This effectively protects the communication cable, reduces environmental damage to the cable, and ensures stable and reliable transmission of pixel information to the host computer.

[0054] In this embodiment of the utility model, the telescopic rod 3 includes a telescopic drive device, which is connected to the host computer.

[0055] The telescopic rod 3 includes a telescopic drive device connected to a host computer, which allows for remote control of the telescopic rod 3's extension and retraction. This makes operation convenient and quick, and enables precise adjustment of the telescopic rod 3's length, thereby improving detection efficiency and accuracy.

[0058] Furthermore, various different implementation methods of this utility model can be arbitrarily combined, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
