[0018] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 A ship paint damage detection device includes a body 1, which can employ a GTS810F Bluetooth coating thickness gauge, a CT200 Bluetooth split thickness gauge, etc. The exterior of the body 1 is waterproofed using existing technology to meet the needs of seawater operations. The body 1 is a model with a built-in Bluetooth interface. A detection probe 6 is externally connected to the body 1. A sealing ring is installed at the interface of the transmission line between the body 1 and the detection probe 6 to achieve a waterproof effect. When the detection probe 6 is working, it is magnetically attached to the ship surface. The paint thickness is determined by measuring the change in distance between the probe and the coating. The measured values ​​are transmitted to a computer wirelessly. The specific working principle is existing technology and will not be elaborated here. A bracket 2 is fixedly connected to the bottom of the body 1. The bracket 2 is fixed to the front of the body 7 of the cleaning robot by bolts or other means. The bracket 2 is located below the camera on the body 7 of the cleaning robot, which can avoid the problem of the bracket 2 interfering with image acquisition. At the same time, it can realize the function of simultaneous detection of image and paint thickness, further improving the detection accuracy of ship paint, facilitating timely repainting operations, and reducing the cost increase caused by paint waste.

[0020] Please see Figure 2 A detection probe 6 is installed in the middle of the front side of the bracket 2. (See reference) Figure 4The detection probe 6 is symmetrically connected to two base plates 3. A spring is connected inside the base plate 3, with the top of the spring connected to the bracket 2. In its natural state, the bottom of the detection probe 6 is flush with the bottom of the cleaning robot body 7, allowing the bottom of the detection probe 6 to contact the outer surface of the ship for paint damage detection. A movable block 31 is fixedly connected inside the base plate 3. The movable block 31 is made of a magnetically attractive material. Above the movable block 31 is a fixed block 21 connected to the bracket 2. The fixed block 21 is an electro-permanent magnet. The power cord of the fixed block 21 is connected to the body 1 and controlled by the corresponding control system. A sleeve is provided outside the movable block 31, which movably fits onto the bottom of the fixed block 21, limiting the vertical movement of the base plate 3. When the fixed block 21 is energized and becomes magnetic, the movable block 31 is magnetically attracted, causing the base plate 3 and the detection probe 6 to move upwards, thus retracting the detection probe 6 and avoiding... To prevent the scale buildup on the detection probe 6 from causing damage during the operation of the robot body 7, when the detection probe 6 needs to inspect the paint surface, the power to the fixing block 21 is disconnected. The base plate 3 and the detection probe 6 will then move closer to the paint surface under the action of the internal connecting spring. At the same time, the detection probe 6 will also be magnetically attracted to the ship's paint surface. Through the cooperation of the fixing block 21 and the movable block 31, the detection probe 6 can be retracted in its non-working state without affecting its normal detection, reducing the external force damage to the detection probe 6 and ensuring its detection accuracy and service life. Meanwhile, the base plate 3 is externally connected to a protective layer 33. The top of the protective layer 33 is connected to the bracket 2, and the protective layer 33 covers the fixing block 21, the movable block 31, and their connecting springs. The protective layer 33 is sealed to prevent external seawater from corroding the internal components. At the same time, the protective layer 33 is a soft material with a certain degree of toughness, which has a certain protective ability and will not affect the up and down movement of the base plate 3.

[0021] Please see Figure 5 The bottom plate 3 is connected to the rear side of the insertion block 32. The top of the insertion block 32 is movably inserted into the bracket 2, which can limit the vertical movement of the bottom plate 3. At the same time, the rear side of the insertion block 32 is provided with a protruding structure, which allows the bottom plate 3 to contact the body 7 of the cleaning robot when the device is installed on it, increasing the fulcrum of the device and thus improving the stability of the device during installation and use.

[0022] Please see Figure 2 The base plate 3 is externally fitted with an outer baffle 4 connected to the bracket 2. The outer baffle 4 is fixedly connected, and an inner baffle 5 connected to the bracket 2 is provided on the inner side of the outer baffle 4. (See reference) Figure 3The outer baffle 4 and inner baffle 5 have interlocking slots, meaning that when the outer baffle 4 and inner baffle 5 are in contact, they are in a closed state. This protects the detection probe 6 and the base plate 3, greatly reducing the risk of damage to these components from debris in the water. (See also...) Figure 5 The inner baffle 5 is connected to the support 2 via a movable rod 51. The movable rod 51 is a structure that can elastically extend and retract. When the water flow resistance is greater than the force required for the deformation of the internal spring of the movable rod 51, the inner baffle 5 moves away from the outer baffle 4. The water flow can pass through the slots on the outer baffle 4 and the inner baffle 5 and the gap between them, which can reduce the water flow resistance on the support 2, thereby reducing the risk of deformation or damage to the support 2 due to external forces, extending the service life of the device, and reducing its later maintenance costs.

[0023] In addition, by setting a spring-connected movable structure on the outside of the probe, a certain buffering and protective effect can be achieved by the movement of the spring when it is used alone, thereby improving the protective performance of the probe.

[0024] The working principle of this invention is as follows: The bracket 2 is fixedly installed on the body 7 of the cleaning robot using existing fixing structures such as bolts, with the detection probe 6 and its external structure positioned below the camera on the body 1. After being put into use, the fixing block 21 is energized via an electrical signal. The magnetic force generated by the energized fixing block 21 is greater than the elastic force of the spring on one side, causing the movable block 31 to be magnetically fixed by the fixing block 21. At this time, the detection probe 6 is in a retracted state. The cleaning robot body 7 performs cleaning work on the outside of the ship according to the set operation. During the movement of the cleaning robot body 7, the outer baffle 4 and the inner baffle 5 block debris in the water, preventing damage to the detection probe 6 and its external structure. When the water flow resistance is high, the inner baffle 5 is affected by the water flow resistance, causing the movable rod 51 to shorten. The water flows through the slots and gaps on the outer baffle 4 and the inner baffle 5, thereby reducing the water flow resistance. The resistance encountered by the cleaning robot body 7 during movement; when the cleaning work is completed and the damage to the ship's paint surface needs to be inspected, the cleaning robot body 7 moves according to the program settings, the camera on the cleaning robot body 7 collects image data accordingly, and at the same time, the fixed block 21 is de-energized. The spring on one side of the fixed block 21 causes the detection probe 6 to move downwards. The robot body 1 is powered on by a remote control signal, the detection probe 6 is powered on and adsorbed on the ship's paint surface. The paint thickness is determined by measuring the change in distance between the detection probe 6 and the coating. The data is simultaneously transmitted to the computer via wireless transmission methods such as Bluetooth. In addition, as the base plate 3 moves up and down with the detection probe 6, the protective layer 33 also extends and retracts, while the protective layer 33 isolates the outside seawater. The insert 32 moves up and down along the insert on the bracket 2 as the base plate 3 moves up and down, so that the base plate 3 moves stably as a whole.
