[0004] The aforementioned patent provides excellent waterproof and corrosion-resistant properties for marine monitoring equipment, making it very convenient to use. When conducting marine monitoring operations on ships, the complex and ever-changing marine environment causes the ship's swaying amplitude to change in real time. This continuous and unstable swaying is directly transmitted to the marine monitoring equipment on the ship, causing the monitoring attitude of the equipment to deviate. Therefore, it is necessary to perform real-time and precise stable control of the equipment's attitude to ensure the normal operation of the monitoring work. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a waterproof, corrosion-resistant, and automatically stabilizing marine inspection device and method, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproof, corrosion-resistant, and automatically attitude-stabilized marine monitoring device, comprising a support frame and a drive unit. The support frame is mounted on a ship. An encoder is installed inside the drive unit. A bearing bracket is fixedly mounted on the top of the support frame. A cylindrical rod is rotatably mounted on the inner wall of the bearing bracket. The output end of the drive unit is fixedly connected to the cylindrical rod. The encoder is used to detect the rotation angle of the cylindrical rod. A mounting frame is fixedly mounted on the circumference of the cylindrical rod. A marine monitoring radar is fixedly mounted on the top of the mounting frame. An attitude detection sensor is installed inside the marine monitoring radar. The attitude detection sensor is used to transmit real-time acquired radar rotation attitude changes to the system. The system receives the attitude detection sensor data. After measuring the data transmitted by the sensor, it is compared with the preset standard attitude to determine whether there is a deviation in the current attitude of the marine monitoring radar. A searchlight is fixedly installed on the circumferential surface of the cylindrical rod. The system also includes: a base, which is fixedly installed on the ship; a hinge frame, which is rotatably installed on the top of the base; an elastic telescopic rod, which is fixedly installed on the side of the hinge frame away from the base; a T-shaped rod, which is fixedly installed on the telescopic end of the elastic telescopic rod; the elastic telescopic rod is used to drive the axial displacement of the T-shaped rod; and a connecting plate, which is rotatably installed on the circumferential surface of the T-shaped rod. The connecting plate is fixedly connected to the bottom of the mounting frame, and the connecting plate also applies an upward pulling force to the telescopic end of the elastic telescopic rod through the T-shaped rod, causing the telescopic end of the elastic telescopic rod to move upward.

[0007] According to the above technical solution, the surface of the marine monitoring radar is provided with an anti-corrosion coating. When the ship is sailing at sea, the waves come into contact with the surface of the marine monitoring radar, and the anti-corrosion coating can greatly reduce the corrosion of seawater. The base is provided with a counterweight plate inside, which is used to improve the stability of the base itself.

[0008] According to the above technical solution, a hollow tube is fixedly installed on the circumferential surface of the elastic telescopic rod, and a circular hole is opened at the top of the hollow tube. The circular hole contacts the telescopic end of the elastic telescopic rod, and the circular hole constrains the telescopic end.

[0009] According to the above technical solution, a circular plate is fixedly installed on the circumferential surface of the output end of the elastic telescopic rod. The circular plate is in contact with the inner wall of the hollow tube. The stable contact between the hollow tube and the circular plate can effectively enhance the stability of the telescopic end of the elastic telescopic rod when it is displaced to the preset maximum distance.

[0010] According to the above technical solution, the base is provided with a support device for stabilizing the marine monitoring radar, and the support device is provided with an auxiliary device for improving the overall displacement stability; the support device includes a metal frame and a support plate, the metal frame is fixedly installed on the top of the base, the support plate is fixedly installed on the top of the metal frame, the support plate is attached to the bottom of the connecting plate, and when the support plate is attached to the connecting plate, it provides continuous support force to the connecting plate. The support plate is used to provide stable support force to the connecting plate. A rectangular groove is opened on the top of the support plate, and a through hole is opened on the bottom of the support plate. The rectangular groove communicates with the through hole.

[0011] According to the above technical solution, a mounting tube is fixedly installed on the surface of the metal frame, a transmission rod slides through the outer wall of the mounting tube, a rectangular plate is fixedly installed on the top of the transmission rod, a pressure plate is fixedly installed on the circumferential surface of the transmission rod, a spring is provided between the mounting tube and the pressure plate, the pressure applied by the connecting plate to the lower rectangular plate is reduced, and the spring in the compressed state begins to elastically recover upward due to the release of pressure.

[0012] According to the above technical solution, the auxiliary device includes a rectangular frame, a slider, a sleeve, and a buffer pad. The rectangular frame is fixedly installed at the bottom of the mounting tube. A groove is provided on the inner wall of the rectangular frame. The slider is slidably installed inside the groove. The sleeve is fixedly installed on the side of the slider away from the groove. The buffer pad is fixedly inserted through the bottom of the rectangular frame. The sleeve is fixedly connected to the bottom of the transmission rod. When the transmission rod moves upward, it will synchronously drive the sleeve to move upward together. The top of the sleeve fits against the buffer pad.

[0013] According to the above technical solution, a friction plate is fixedly installed on the circumferential surface of the slider, a friction strip is fixed on the inner wall of the rectangular frame, the friction plate contacts the outer wall of the friction strip, and the two sides of the friction plate continuously contact the fixed friction strip and generate friction. The resulting frictional resistance is transmitted to the transmission rod through the slider and the sleeve.

[0014] This invention provides a waterproof, corrosion-resistant, and automatically attitude-stabilized marine inspection device. It offers the following advantages: (1) The waterproof, corrosion-resistant and automatically stabilizing marine monitoring equipment has an encoder inside the drive device that detects the rotation angle of the cylindrical rod in real time until the radar returns to the standard attitude. By monitoring in real time and driving the cylindrical rod in a timely manner, the marine monitoring radar can maintain a stable attitude, enhance the adaptability of the marine monitoring radar in complex sea conditions, and make the monitoring work more stable. At the same time, the elastic telescopic rod generates a reverse elastic force, which will form a continuous downward pull on the side of the mounting frame that is in the raised state. By applying a continuous downward pull on the side of the mounting frame that is raised, the additional load on the side of the mounting frame that is raised can be effectively offset, maintaining the level and stability of the overall attitude, and ensuring that the detection data can truly reflect the marine environmental parameters.

[0015] (2) The waterproof, corrosion-resistant and automatically stabilizing marine inspection equipment has a flexible telescopic rod whose telescopic end is constrained by a circular hole. During the displacement process, it always maintains a stable displacement trajectory. Through the coordinated cooperation of the hollow tube and the circular plate, the operational stability of the flexible telescopic rod during the entire telescopic process is effectively guaranteed, enabling it to continuously provide a stable and reliable downward pulling force for the mounting frame.

[0016] (3) The waterproof, corrosion-resistant and automatically stabilizing marine detection equipment has a rectangular plate that applies a controllable auxiliary thrust to the bottom of the connecting plate. The rectangular plates on both sides work together to apply a stable auxiliary thrust to the connecting plate, which can effectively share the initial start-up load of the drive device and reduce the operating pressure of the drive device. At the same time, the receiving plate and the rectangular plate form a cooperative support structure to provide stable support for the receiving plate. By providing stable support for the connecting plate in the standby state, the connecting plate is always in the preset initial position. When the device is started next time, the drive device can directly drive the mounting frame into the working state, thereby effectively improving the monitoring efficiency.

[0017] (4) The waterproof, corrosion-resistant and automatically stabilizing marine detection equipment has friction plates on both sides and friction strips that form controllable friction resistance. Through the friction between the friction plates and friction strips, the displacement stability of the transmission rod is further improved, thereby ensuring that the auxiliary support force transmitted from the transmission rod to the connecting plate remains uniform. At the same time, the buffer pad will actively absorb the collision energy and slow down the downward movement speed of the sleeve and transmission rod. Through the friction resistance and the efficient absorption of the end collision by the buffer pad, mechanical collisions can be prevented between the mounting frame and the marine monitoring radar during the reset process, thereby improving the safety of the marine monitoring radar during reset.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 8 One embodiment of the present invention is: a waterproof, corrosion-resistant, and automatically attitude-stabilized marine monitoring device, comprising a support frame 1 and a drive device. The support frame 1 is mounted on a ship. An encoder is installed inside the drive device. A bearing bracket 2 is fixedly mounted on the top of the support frame 1. A cylindrical rod 3 is rotatably mounted on the inner wall of the bearing bracket 2. The output end of the drive device is fixedly connected to the cylindrical rod 3. The encoder is used to detect the rotation angle of the cylindrical rod 3. A mounting frame 4 is fixedly mounted on the circumferential surface of the cylindrical rod 3. A marine monitoring radar 5 is fixedly mounted on the top of the mounting frame 4. An attitude detection sensor is installed inside the marine monitoring radar 5. The attitude detection sensor is used to transmit the real-time acquired radar rotation attitude changes to the system. The system includes a searchlight 6 and a base 7, which is fixedly mounted on the ship; a hinge frame 8, which is rotatably mounted on the top of the base 7; an elastic telescopic rod 9, which is fixedly mounted on the side of the hinge frame 8 away from the base 7; a T-shaped rod 10, which is fixedly mounted on the telescopic end of the elastic telescopic rod 9; the elastic telescopic rod 9 is used to drive the T-shaped rod 10 to move axially; and a connecting plate 11, which is rotatably mounted on the circumferential surface of the T-shaped rod 10 and fixedly connected to the bottom of the mounting frame 4. By real-time monitoring and timely driving of the cylindrical rod 3, the marine monitoring radar 5 can maintain a stable attitude, enhance the adaptability of the marine monitoring radar 5 in complex sea conditions, and make the monitoring work more stable.

[0022] The surface of the marine monitoring radar 5 is coated with an anti-corrosion coating, and the base 7 is equipped with a counterweight plate 12. The counterweight plate 12 is used to improve the stability of the base 7 itself. By adding the counterweight plate 12, the stability of the base 7 when installed on the ship is ensured, and its ability to cope with various environments is enhanced.

[0023] A hollow tube 13 is fixedly installed on the circumferential surface of the elastic telescopic rod 9. A circular hole is opened at the top of the hollow tube 13, and the circular hole contacts the telescopic end of the elastic telescopic rod 9. By ensuring that the telescopic end always maintains a stable displacement trajectory during the displacement process, the radial sway of the telescopic end during the displacement is effectively suppressed.

[0024] A circular plate 14 is fixedly installed on the circumferential surface of the output end of the elastic telescopic rod 9. The circular plate 14 contacts the inner wall of the hollow tube 13. Through the cooperation between the hollow tube 13 and the circular plate 14, the operational stability of the elastic telescopic rod 9 during the entire telescopic process is effectively guaranteed.

[0025] A testing method for a waterproof, corrosion-resistant, and automatically attitude-stabilized marine inspection device, using the aforementioned waterproof, corrosion-resistant, and automatically attitude-stabilized marine inspection device, includes the following steps: Step 1: During operation, the attitude detection sensor inside the marine monitoring radar 5 acquires the current rotation attitude data in real time and transmits the acquired data to the system. Step 2: After receiving the data transmitted by the attitude detection sensor, the system compares it with the preset standard attitude to determine whether there is a deviation in the attitude of the current marine monitoring radar 5. Step 3: When the system detects an attitude deviation in the marine monitoring radar 5, it sends a command to the drive device. After receiving the command, the drive device drives the cylindrical rod 3 to rotate. The cylindrical rod 3 drives the mounting frame 4 and the searchlight 6 to rotate synchronously. The mounting frame 4 further drives the marine monitoring radar 5 to rotate synchronously. Step 4: The encoder inside the drive unit detects the rotation angle of the cylindrical rod 3 in real time and feeds the data back to the system. When the encoder detects that the rotation angle has reached the value required to eliminate the deviation, the drive unit stops working and the radar returns to the standard posture.

[0026] In this embodiment, the attitude detection sensor inside the marine monitoring radar 5 acquires the current rotational attitude data in real time and transmits the acquired data to the system. After receiving the data transmitted by the attitude detection sensor, the system compares it with the preset standard attitude to determine whether there is a deviation in the current attitude of the marine monitoring radar 5. When the system detects that there is an attitude deviation in the marine monitoring radar 5, it sends a command to the drive device. After receiving the command, the drive device drives the cylindrical rod 3 to rotate. The cylindrical rod 3 drives the mounting frame 4 and the searchlight 6 to rotate synchronously. The mounting frame 4 further drives the marine monitoring radar 5 to rotate synchronously. The encoder inside the drive device detects the rotation angle of the cylindrical rod 3 in real time and feeds the data back to the system. When the encoder detects that the rotation angle has reached the value required to eliminate the deviation, the drive device stops working, and the radar returns to the standard attitude. By monitoring in real time and driving the cylindrical rod 3 in a timely manner, the marine monitoring radar 5 can maintain a stable attitude, enhance the adaptability of the marine monitoring radar 5 in complex sea conditions, and make the monitoring work more stable. When the cylindrical rod 3 drives the mounting frame 4 to rotate away from the base 7, the mounting frame 4 synchronously drives the connecting plate 11 to move upward. During the displacement, the connecting plate 11 always remains in close contact with the mounting frame 4 and rotates together with the mounting frame 4. As the connecting plate 11 rotates and moves upward, it will further drive the elastic telescopic rod 9 to rotate synchronously. The elastic telescopic rod 9 then drives the hinge frame 8 to complete the rotation action around the base 7. At the same time, the connecting plate 11 will also apply an upward pulling force to the telescopic end of the elastic telescopic rod 9 through the T-shaped rod 10, causing the telescopic end of the elastic telescopic rod 9 to move upward, thereby generating a reverse elastic force inside. This reverse elastic force will act on the bottom area of ​​the mounting frame 4 along the T-shaped rod 10 and the connecting plate 11. This force will form a continuous downward pulling force on the side of the mounting frame 4 that is in the raised state, thereby achieving stable control of the attitude of the mounting frame 4. By applying a continuous downward pulling force to the raised side of the mounting frame 4, the additional load on the raised side of the mounting frame 4 can be effectively offset, maintaining the horizontal and stable overall attitude, and ensuring that the detection data can truly reflect the marine environmental parameters. When the telescopic end of the elastic telescopic rod 9 moves upward, it continuously contacts the circular hole of the hollow tube 13. This circular hole constrains the telescopic end, ensuring that the telescopic end maintains a stable displacement trajectory during the displacement process, effectively suppressing the radial sway of the telescopic end during displacement. At the same time, the upward movement of the telescopic end will synchronously drive the annular plate 14 to move together. When the annular plate 14 moves upward to contact the top of the inner wall of the hollow tube 13, the cylindrical rod 3 has rotated to the maximum value of the preset angle. At this time, the drive device will immediately stop driving, thereby precisely limiting the rotation angle of the mounting frame 4 and preventing it from exceeding the safe range. The stable contact between the hollow tube 13 and the annular plate 14 can effectively enhance the stability of the telescopic end of the elastic telescopic rod 9 when it moves to the preset maximum distance. Through the coordinated cooperation of the hollow tube 13 and the annular plate 14, the operational stability of the elastic telescopic rod 9 during the entire telescopic process is effectively guaranteed, enabling it to continuously provide a stable and reliable downward pulling force for the mounting frame 4.

[0027] Please see Figure 1 - Figure 8 Based on the above embodiments, in another embodiment of the present invention, the base 7 is provided with a support device for stabilizing the marine monitoring radar 5, and the support device is provided with an auxiliary device for improving the overall displacement stability; the support device includes a metal frame 21 and a support plate 22, the metal frame 21 is fixedly installed on the top of the base 7, the support plate 22 is fixedly installed on the top of the metal frame 21, the support plate 22 is attached to the bottom of the connecting plate 11, the support plate 22 is used to provide stable support force for the connecting plate 11, the top of the support plate 22 is provided with a rectangular groove, the bottom of the support plate 22 is provided with a through hole, and the rectangular groove communicates with the through hole. By providing stable support force for the connecting plate 11 in the standby state, it is ensured that the connecting plate 11 is always in the preset initial position.

[0028] A mounting tube 23 is fixedly installed on the surface of the metal frame 21. A transmission rod 24 slides through the outer wall of the mounting tube 23. A rectangular plate 25 is fixedly installed on the top of the transmission rod 24. A pressure plate 26 is fixedly installed on the circumferential surface of the transmission rod 24. A spring 27 is provided between the mounting tube 23 and the pressure plate 26. The rectangular plates 25 arranged symmetrically on both sides jointly apply a stable auxiliary thrust to the connecting plate 11, which can effectively share the initial starting load of the drive device.

[0029] The auxiliary device includes a rectangular frame 31, a slider 32, a sleeve 33, and a buffer pad 34. The rectangular frame 31 is fixedly installed at the bottom of the mounting tube 23. A groove is provided on the inner wall of the rectangular frame 31. The slider 32 is slidably installed inside the groove. The sleeve 33 is fixedly installed on the side of the slider 32 away from the groove. The buffer pad 34 is fixedly inserted through the bottom of the rectangular frame 31. The sleeve 33 is fixedly connected to the bottom of the transmission rod 24. The top of the sleeve 33 fits against the buffer pad 34. Through the efficient absorption of the end collision by the buffer pad 34, mechanical collisions can be prevented between the mounting frame 4 and the marine monitoring radar 5 during the resetting process.

[0030] A friction plate 35 is fixedly installed on the circumferential surface of the slider 32, and a friction strip 36 is fixed on the inner wall of the rectangular frame 31. The friction plate 35 contacts the outer wall of the friction strip 36. Through the friction between the friction plate 35 and the friction strip 36, the displacement stability of the transmission rod 24 is further improved, thereby ensuring that the auxiliary support force transmitted by the transmission rod 24 to the connecting plate 11 remains uniform.

[0031] In this embodiment, when the connecting plate 11 moves upward and gradually disengages from the receiving plate 22, the pressure exerted by the connecting plate 11 on the lower rectangular plate 25 gradually decreases. At this time, the spring 27, which is in a compressed state, begins to elastically recover upward due to the release of pressure. The recovery force of the spring 27 will push the pressure plate 26 to move upward. The pressure plate 26 drives the transmission rod 24 to move upward together. The transmission rod 24 further drives the rectangular plate 25 to move upward. During the upward movement of the rectangular plate 25, it will apply a controllable auxiliary thrust to the bottom of the connecting plate 11 until the connecting plate 11 continues to move upward and completely disengages from the rectangular plate 25. By having the rectangular plates 25 arranged symmetrically on both sides jointly apply a stable auxiliary thrust to the connecting plate 11, the initial starting load of the drive device can be effectively shared, thereby reducing the operating pressure of the drive device. After the monitoring operation is completed, the cylindrical rod 3 initiates a reset, driving the mounting frame 4 and the marine monitoring radar 5 to reset to their initial positions. During this reset process, the mounting frame 4 synchronously moves the connecting plate 11 downwards. As the connecting plate 11 moves downwards, it first contacts the rectangular plate 25 and applies downward pressure to it. Under this pressure, the rectangular plate 25 drives the transmission rod 24 to move downwards synchronously. The transmission rod 24 further drives the pressure plate 26 downwards, causing the pressure plate 26 to continuously compress the spring 27 below during its downward movement, forcing the spring 27 to gradually contract and advance. When in compression state, the compressed spring 27 applies a reverse elastic force upward due to its elastic characteristics until the connecting plate 11 moves downward and fits against the receiving plate 22 to complete the reset. After the reset, the receiving plate 22 and the rectangular plate 25 form a cooperative support structure, which together provide stable support force for the receiving plate 22, so that it remains stable in the standby state. By providing stable support force for the connecting plate 11 in the standby state, it is ensured that the connecting plate 11 is always in the preset initial position. When the next start-up is performed, the drive device can directly drive the mounting bracket 4 into the working state, thereby effectively improving the monitoring efficiency. When the transmission rod 24 moves upward, it will simultaneously drive the sleeve 33 to move upward as well, so that the sleeve 33 gradually loses contact with the buffer pad 34. At the same time, the sleeve 33 drives the slider 32 to move smoothly upward along the slide groove. The slider 32 further drives the friction plate 35 to move upward. During this process, the two sides of the friction plate 35 continuously contact the fixed friction strip 36 and generate friction. The resulting frictional resistance is transmitted to the transmission rod 24 through the slider 32 and the sleeve 33. This controllable frictional resistance can effectively suppress the displacement speed fluctuation of the transmission rod 24 and ensure that it remains stable throughout the entire movement. Through the friction between the friction plate 35 and the friction strip 36, the displacement stability of the transmission rod 24 is further improved, thereby ensuring that the auxiliary support force transmitted by the transmission rod 24 to the connecting plate 11 remains uniform. When the transmission rod 24 moves downward, it simultaneously drives the sleeve 33 and the slider 32 to move downward together. The slider 32 then drives the friction plate 35 to move downward. During this process, the sleeve 33 moves downward smoothly under the constraint of frictional resistance until the sleeve 33 contacts the buffer pad 34 below. The collision generated at the moment of contact will cause the buffer pad 34 to undergo elastic deformation. During the deformation process, the buffer pad 34 will actively absorb the collision energy, further slowing down the downward speed of the sleeve 33 and the transmission rod 24, effectively avoiding hard collision of the transmission rod 24 at the end of the displacement, ensuring the accuracy of the overall movement. Through the frictional resistance and the efficient absorption of the end collision by the buffer pad 34, mechanical collisions between the mounting frame 4 and the marine monitoring radar 5 during the resetting process can be prevented, thereby improving the safety of the marine monitoring radar 5 during resetting.

9. A testing method for a waterproof, corrosion-resistant, and automatically attitude-stabilized marine detection device, using the waterproof, corrosion-resistant, and automatically attitude-stabilized marine detection device as described in claim 8, characterized in that... Includes the following steps: Step 1: During operation, the attitude detection sensor inside the marine monitoring radar (5) acquires the current rotation attitude data in real time and transmits the acquired data to the system. Step 2: After receiving the data transmitted by the attitude detection sensor, the system compares it with the preset standard attitude to determine whether there is a deviation in the attitude of the current marine monitoring radar (5); Step 3: When the system detects an attitude deviation in the marine monitoring radar (5), it sends a command to the drive device. After receiving the command, the drive device drives the cylindrical rod (3) to rotate. The cylindrical rod (3) drives the mounting frame (4) and the searchlight (6) to rotate synchronously. The mounting frame (4) further drives the marine monitoring radar (5) to rotate synchronously. Step 4: The encoder inside the drive unit detects the rotation angle of the cylindrical rod (3) in real time and feeds the data back to the system. When the encoder detects that the rotation angle has reached the value required to eliminate the deviation, the drive unit stops working and the radar returns to the standard posture.
