[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] Reference below Figure 1-Figure 3A rust removal device 100 and a rust removal method for rust removal by hydroxyl reaction according to an embodiment of the present invention are described.

[0039] like Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, a rust removal device 100 for rust removal by hydroxyl reaction is provided. The rust removal device 100 is used to remove rust from a rust removal device 200. The rust removal device 100 includes:

[0040] The device body 10 and the driving mechanism 20 are provided on the device body 10 and are used to drive the device body 10 to move to the target position of the device 200 to be rust-removed;

[0041] An electrolysis mechanism 30 is provided in the device body 10 and is used to electrolyze the first liquid to generate a target liquid having hydroxyl groups;

[0042] The spray conduit 40 is provided in the device body 10 and is connected to the electrolysis mechanism 30 so that the target liquid flows into the spray conduit 40 . The spray conduit 40 is used to spray the target liquid toward the rust layer of the device 200 to be derusted.

[0043] The first direction is Figure 1 The X direction in the second direction is Figure 1 In the Y direction, the device body 10 can be made of corrosion-resistant materials, such as stainless steel, titanium alloy and other corrosion-resistant materials, so as to effectively extend the service life of the rust removal device 100. The driving mechanism 20 may include a propeller, an electric motor, and other mechanisms, which can be reasonably selected and set according to actual conditions to meet the use requirements of the rust removal device 100. The driving mechanism 20 is arranged on the device body 10. In some embodiments of the present invention, the driving mechanism 20 and the device body 10 can be fixedly connected by bolts, or the driving mechanism 20 and the device body 10 can be fixedly connected by welding, but the present invention is not limited to this. The driving mechanism 20 and the device body 10 can also be fixedly connected by other means, as long as the driving mechanism 20 is arranged on the device body 10.

[0044] The drive mechanism 20 is used to drive the device body 10 to the target position of the device 200 to be rust-removed. This reduces incomplete or repeated rust removal due to positional deviations, thereby improving rust removal efficiency. The drive mechanism 20 is characterized by rapid response, capable of completing the movement and positioning of the device body 10 in a short period of time, shortening the preparation time for rust removal operations and further improving overall rust removal efficiency. The drive mechanism 20 also provides stable support and power for the device body 10, ensuring that the device body 10 maintains a stable posture and position during the rust removal process.

[0045] The electrolysis mechanism 30 is provided in the device body 10. The electrolysis mechanism 30 and the device body 10 can be fixedly connected by bolts, or the electrolysis mechanism 30 and the device body 10 can be fixedly connected by welding, but the present invention is not limited thereto. The electrolysis mechanism 30 and the device body 10 can also be fixedly connected by other means, as long as the electrolysis mechanism 30 is provided in the device body 10. The electrolysis mechanism 30 can be an electrolysis head, an electrolysis cell, or other mechanism. The electrolysis mechanism 30 is in communication with the outside world and is provided with a one-way valve to allow a first liquid to enter the electrolysis mechanism 30 in one direction through the one-way valve. The electrolysis mechanism 30 is used to electrolyze the first liquid to produce a target liquid having hydroxyl groups. The first liquid is water, and the electrolysis mechanism 30 is used to electrolyze water to produce a target liquid having hydroxyl groups.

[0046] The injection conduit 40 is provided on the device body 10. The injection conduit 40 and the device body 10 can be fixedly connected by welding, or the injection conduit 40 and the device body 10 can be fixedly connected by bonding, but the present invention is not limited thereto. The injection conduit 40 and the device body 10 can also be fixedly connected by other means, as long as the injection conduit 40 is provided on the device body 10. A driving pump can be provided between the injection conduit 40 and the electrolysis mechanism 30. The injection conduit 40 is connected to the electrolysis mechanism 30. The driving pump drives the target liquid to flow into the injection conduit 40 and drives the target liquid to be sprayed toward the rust layer of the device 200 to be rust-removed. The hydroxyl group in the target liquid reacts with the rust layer to convert the rust layer into a water-soluble substance (Fe2O3+6OH - +3H2O→2[Fe(OH)]4 - ). The spraying method helps the hydroxyl groups in the target liquid to fully contact the rust layer. Compared with the traditional immersion or smearing method, the spraying method can make the target liquid cover the rust layer more quickly and react deeply inside the rust layer, thereby enhancing the reaction effect. The spraying method also helps the target liquid to impact and peel off the dirt in the rust layer. The spraying conduit 40 is usually made of corrosion-resistant and wear-resistant materials to ensure its long-term stable operation. In this way, the damage to the rust removal device 200 caused by traditional mechanical grinding is avoided, the rust removal efficiency is significantly improved, and it is also suitable for the rust removal treatment of complex-shaped and precise rust removal devices 200, thereby improving the applicability of the rust removal device 100.

[0047] Furthermore, as an embodiment of the present invention, the device to be rusted 200 can be a steam generator, and the rust removal device 100 is used to perform rust removal operations on the inside and pipelines of the steam generator. The steam generator can be filled with a first liquid (water). There can be multiple rust removal devices 100, and multiple rust removal devices 100 can be moved simultaneously in the device to be rusted 200 to the rust layers at multiple target positions to perform rust removal operations respectively, thereby greatly improving the rust removal efficiency.

[0048] According to the rust removal device 100 for rust removal by hydroxyl reaction according to an embodiment of the present invention, the driving mechanism 20 drives the device body 10 to move to the target position of the device to be rusted 200, and the injection conduit 40 is used to spray the target liquid onto the rust layer of the device to be rusted 200. The target liquid reacts with the rust layer to remove the rust layer, thereby avoiding damage to the device to be rusted 200 by traditional mechanical polishing, significantly improving the rust removal efficiency, and being suitable for rust removal treatment of complex-shaped and precise devices to be rusted 200, thereby improving the applicability of the rust removal device 100.

[0049] According to some embodiments of the present invention, Figure 1 As shown, the driving mechanism 20 includes a first propeller 21 . The first propeller 21 is located at one end of the device body 10 along a first direction. The first propeller 21 is rotatably provided on the device body 10 .

[0050] Among them, the rotation of the first propeller 21 can generate a strong propulsion force, pushing the device body 10 to move in the liquid or gas medium, efficiently and stably, so that the rust removal device 100 can quickly move to the rust layer in the device to be rusted 200, thereby indirectly improving the rust removal efficiency of the rust removal device 100. Along the first direction, the first propeller 21 is located at one end of the device body 10. The first propeller 21 is rotatably provided on the device body 10. By rotating the first propeller 21, the device body 10 can be moved along the first direction. By changing the rotation direction of the first propeller 21, the movement direction of the device body 10 along the first direction can be accurately controlled. By changing the rotation speed of the first propeller 21, the movement speed of the device body 10 can be controlled to drive the device body 10 to move quickly and accurately to the target position of the device to be rusted 200, thereby reducing the time for the rust removal device 100 to reach the target position, shortening the rust removal process, and thereby effectively improving the rust removal efficiency of the rust removal device 100.

[0051] According to some embodiments of the present invention, Figure 1 As shown, the driving mechanism 20 may further include: a plurality of second propellers 22 , which are arranged around the device body 10 along the circumference of the device body 10 , and the rotation axis of each second propeller 22 is perpendicular to the first direction.

[0052] The drive mechanism 20 may include two, three, four, or other numbers of second propellers 22, but the present invention is not limited thereto. The drive mechanism 20 may also include other numbers of second propellers 22, as long as the drive mechanism 20 includes multiple second propellers 22. The multiple second propellers 22 may be arranged around the device body 10 along the circumference of the device body 10, with the rotation axis of each second propeller 22 perpendicular to the first direction, thereby generating omnidirectional propulsion, thereby enabling the device body 10 to achieve more flexible and stable movement in a liquid or gas medium.

[0053] By independently controlling the rotation speed and direction of each second propeller 22, vector propulsion control of the device body 10 in three-dimensional space can be achieved, the moving direction and angle of the device body 10 can be changed, and the target position in the device to be rusted 200 can be accurately reached, so as to accurately remove the rust layer at different target positions in the device to be rusted 200, and the rust layer on the surface of a flat surface, a curved surface or a complex structure can be effectively treated. Various obstacles, narrow spaces or special structures may exist in the device to be rusted 200. The design of multiple second propellers 22 enables the device body 10 to flexibly cope with these complex environments, easily bypass obstacles or enter narrow spaces to perform rust removal operations, so that the rust removal device 100 can cover the rust layer more efficiently, reduce repeated operations and omissions, and thus improve the rust removal efficiency of the rust removal device 100.

[0054] According to some embodiments of the present invention, Figure 1 As shown, two second propellers 22 may be provided, and the two second propellers 22 are arranged along the second direction and are respectively located on opposite sides of the device body 10, and the first direction and the second direction are perpendicular.

[0055] Among them, the two second propellers 22 are arranged along the second direction and are respectively located on opposite sides of the device body 10, which helps to maintain the balance and stability of the device body 10. By independently controlling the rotation speed and direction of the two second propellers 22, the device body 10 can be moved and turned in a plane perpendicular to the first direction. For example, when the two second propellers 22 have the same direction, the rotation speed of the left second propeller 22 increases and the rotation speed of the right second propeller 22 decreases, the device body 10 will move to the right; conversely, the device body 10 will move to the left. The use of the two second propellers 22 in conjunction with the first propeller 21 can achieve flexible movement and turning of the device body 10 in three-dimensional space, so that the device body 10 can easily bypass obstacles or enter narrow spaces for rust removal operations, so that the rust removal device 100 can more efficiently cover the rust layer, reduce repeated operations and omissions, and thus improve the rust removal efficiency of the rust removal device 100.

[0056] According to some embodiments of the present invention, the driving mechanism 20 may further include: a plurality of driving motors, the plurality of driving motors being disposed in the device body 10 , and the plurality of driving motors being transmission-connected to the first propeller 21 and the plurality of second propellers 22 , respectively.

[0057] Among them, multiple drive motors are arranged in the device body 10, and the drive motors and the device body 10 can be fixedly connected by welding, or the drive motors and the device body 10 can be fixedly connected by snap-fitting, but the present invention is not limited to this. The drive motors and the device body 10 can also be fixedly connected by other means, as long as multiple drive motors are arranged in the device body 10. Multiple drive motors are respectively connected to the first propeller 21 and the multiple second propellers 22 in a transmission manner, so that the speed and direction of the first propeller 21 and the multiple second propellers 22 can be adjusted separately, thereby realizing the precise movement and steering of the device body 10 in three-dimensional space. Multiple drive motors work together to provide powerful power output, so that the device body 10 can respond quickly and reach the target position. In complex or dynamic environments, such as narrow spaces or areas with many obstacles, multiple drive motors can flexibly adjust the output so that the device body 10 can bypass obstacles or adapt to spatial limitations, thereby improving the adaptability and success rate of the device in rust removal operations.

[0058] According to some embodiments of the present invention, Figure 1 As shown, the device body 10 may be formed with a plurality of mounting slots 11 , and the plurality of mounting slots 11 correspond one-to-one to the plurality of second propellers 22 , and the second propellers 22 are installed in the corresponding mounting slots 11 .

[0059] The device body 10 is formed with a plurality of mounting slots 11. In some embodiments of the present invention, the device body 10 may be formed with two, three, four, or other numbers of mounting slots 11, but the present invention is not limited thereto. The device body 10 may also be formed with other numbers of mounting slots 11, as long as the device body 10 is formed with a plurality of mounting slots 11. The present invention is described using an example in which there are two mounting slots 11. The two mounting slots 11 correspond one-to-one to the two second propellers 22, and the second propellers 22 are installed in the corresponding mounting slots 11.

[0060] The design of mounting slot 11 allows for precise installation of second propeller 22 within device body 10, ensuring accurate relative positioning between the second propeller 22 and device body 10. This helps maintain the balance and stability of device body 10 and reduces vibration or instability caused by installation deviations. Mounting slot 11 provides a secure mounting space for second propeller 22, preventing it from loosening or falling off during high-speed rotation. This secure installation improves the overall reliability and safety of device body 10 and extends its service life.

[0061] According to some embodiments of the present invention, Figure 1 As shown, the jet duct 40 and the first propeller 21 are provided at the same end of the device body 10 . There are multiple jet ducts 40 , and the multiple jet ducts 40 are arranged around the first propeller 21 along the circumference of the device body 10 .

[0062] Among them, the first propeller 21 serves as the driving mechanism 20 of the device body 10, generating thrust to the device body 10 along the first direction. The injection duct 40 and the first propeller 21 are arranged at the same end of the device body 10 so that the device body 10 can hover accurately in a complex structural area, so that the rust removal device 100 can adapt to a small space, and multiple injection ducts 40 are arranged around the first propeller 21 along the circumference of the device body 10, which can accurately control the injection direction of the target liquid with hydroxyl groups in the injection duct 40, ensuring that the rust removal operation covers multiple corners of the target position, thereby improving the rust removal accuracy and efficiency of the rust removal device 100. In addition, the first propeller 21 may generate a certain amount of water flow or air flow during operation, which can form a synergistic effect with the injected target liquid to enhance the rust removal effect. For example, the water flow can wash away the rust residue decomposed by the hydroxyl group and keep the working surface clean. The coordinated operation of the injection duct 40 and the first propeller 21 can reduce unnecessary movement and adjustment time and improve overall operation efficiency. Compared to traditional chemical rust removal methods, hydroxyl rust removal does not produce harmful waste liquids and exhaust gases, and is less polluting to the environment. Hydroxyl rust removal technology meets the requirements of green and sustainable development and contributes to environmental protection.

[0063] According to some embodiments of the present invention, Figure 1 As shown, the rust removal device 100 may further include: a separator 12, the separator 12 and the first propeller 21 are arranged at the same end of the device body 10 and fixed to the device body 10, the separator 12 is annular and is sleeved on the first propeller 21, and the separator 12 is formed with a through hole 13.

[0064] The separator 12 and the first propeller 21 are disposed at the same end of the device body 10 and are fixed to the device body 10. In some embodiments of the present invention, the separator 12 and the device body 10 may be fixedly connected by welding, or the separator 12 and the device body 10 may be fixedly connected by bolts, but the present invention is not limited thereto. The separator 12 and the device body 10 may be fixedly connected by other means, and the separator 12 may be fixed to the device body 10. The separator 12 is annular and is sleeved around the first propeller 21. The separator 12 is disposed between the first propeller 21 and the jet duct 40, and can separate the first propeller 21 from the jet duct 40, effectively avoiding the risk of the first propeller 21 cutting the jet duct 40 during operation. In addition, the jet duct 40 and the separator 12 can be fixedly connected, which can increase the stability of the jet duct 40 and reduce the risk of the jet duct 40 tilting. The separator 12 can be formed with a through hole 13, which is used to reduce the material used in the separator 12 to reduce the weight of the separator 12, thereby reducing the weight of the entire rust removal device 100, reducing the load of the driving mechanism 20, extending the life of the rust removal device 100, and thus improving the rust removal efficiency of the rust removal device 100.

[0065] According to some embodiments of the present invention, the rust removal device 100 may further include: a detection mechanism and a controller, the detection mechanism and the controller are arranged on the device body 10, the detection mechanism is used to detect the rust layer, the controller is communicatively connected with the driving mechanism 20, the detection mechanism, and the electrolysis mechanism 30, and the controller is configured to control the operation of the driving mechanism 20 and the electrolysis mechanism 30 according to the detection information of the detection mechanism.

[0066] The detection mechanism can be a recognition sensor, camera, or other mechanism. The present invention uses a color recognition sensor as an example for description. The color of the rust layer is reddish-brown. The detection mechanism and controller are located in the device body 10. The detection mechanism detects the color of the rust layer to detect the location of the rust layer. The controller can be wirelessly connected to the drive mechanism 20, the detection mechanism, and the electrolysis mechanism 30, so that the controller is configured to control the operation of the drive mechanism 20 and the electrolysis mechanism 30 based on the detection information from the detection mechanism. Specifically, after the detection mechanism detects the location of the rust layer, the controller controls the drive mechanism 20 to move the device body 10 toward the rust layer based on the detection information from the detection mechanism. The controller also controls the electrolysis mechanism 30 to decompose the first liquid to produce a target liquid containing hydroxyl groups, and sprays the target liquid toward the rust layer through the spray conduit 40. The target liquid reacts with the rust layer, converting the rust layer into a substance soluble in the first liquid. The impact force of the spray from the spray conduit 40 toward the rust layer can peel off dirt and other impurities in the rust layer that are insoluble in the first liquid, thereby completing the rust removal operation.

[0067] According to some embodiments of the present invention, the rust removal device 100 also includes: a battery, which is arranged in the device body 10, and the battery is used to power the controller, the driving mechanism 20, the detection mechanism, and the electrolysis mechanism 30, and can get rid of dependence on external power supply, so that the rust removal device 100 is suitable for high-altitude and underwater operations, and enables the rust removal device 100 to move autonomously, expand the rust removal range of the rust removal device 100, and does not require the installation of external cables, thereby reducing costs.

[0068] According to a rust removal method of a rust removal device according to an embodiment of the present invention, the rust removal device is the rust removal device of the above embodiment, and the rust removal method includes:

[0069] S1, injecting a first liquid into the device to be derusted.

[0070] The device to be derusted may be a steam generator, the first liquid is water, the derusting device is used to derust the inner wall and pipeline of the steam generator, and injecting water into the steam generator can create a liquid derusting environment for the derusting device.

[0071] S2, placing the rust removal device into the device to be rust removed.

[0072] The rust removal device is placed in the steam generator and can move autonomously in water so as to move to the rust layer position in the steam generator.

[0073] S3, detecting the position of the rust layer of the device to be rust-removed, and driving the rust-removing device to move to the target position of the device to be rust-removed.

[0074] Among them, the detection mechanism on the rust removal device can detect the position of the rust layer of the device to be rusted by identifying the color of the rust layer and feedback it to the controller. The controller controls the driving mechanism to drive the rust removal device to the target position of the device to be rusted based on the detection information of the detection mechanism, so that the injection conduit on the rust removal device is aligned with the rust layer, ensuring the targetedness of subsequent rust removal operations.

[0075] S4, controlling the electrolysis mechanism to electrolyze the first liquid to generate a target liquid having hydroxyl groups.

[0076] Among them, the electrolysis mechanism is connected to water so that water can enter the electrolysis mechanism, and the controller is communicated with the electrolysis mechanism. The controller controls the electrolysis mechanism to electrolyze water to produce a target liquid with hydroxyl groups according to the detection information of the detection mechanism, providing the required target liquid for the transformation of the rust layer.

[0077] S5, controlling the spray conduit to spray the target liquid toward the rust layer.

[0078] A drive pump may be provided between the injection conduit and the electrolysis mechanism, the drive pump being in communication with a controller. The controller controls the drive pump to drive the target liquid to be injected from the injection conduit toward the rust layer, so that the target liquid reacts with the rust layer to convert the rust layer into a water-soluble substance. During the process of the controller controlling the injection conduit to inject the target liquid toward the rust layer, the controller may control the injection conduit to gradually increase the injection speed toward the rust layer, or the controller may change the injection speed toward the rust layer according to the detection information of the detection mechanism. For example, when the reddish-brown color of the rust layer gradually decreases and disappears, the controller may increase the injection speed toward the rust layer, thereby increasing the impact force of the target liquid to peel off the dirt and impurities in the rust layer. When the rust layer in the steam generator is completely removed, the controller controls the drive mechanism to drive the rust removal device to move to the outlet of the steam generator and open the outlet to release the water in the steam generator. The rust removal device flows out of the steam generator along with the water. After the rust removal device is recovered, the steam generator is repeatedly rinsed with clean water and dried, thereby completing the rust removal operation.
