[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] At least one embodiment of the present application provides a pipeline anti-corrosion inspection and disposal tool, which is mainly used in the seawater system of a nuclear power plant. Figures 1 to 3 The pipeline anti-corrosion inspection and disposal tool comprises a pipeline crawling and carrying platform 1, a transverse driving component 2, a coating thickness measuring component 3, a grinding and dust collecting component 4, and a spraying component 5. The transverse driving component 2 is fixedly mounted on the front of the pipeline crawling and carrying platform 1. The coating thickness measuring component 3, the grinding and dust collecting component 4, and the spraying component 5 are detachably mounted on the transverse driving component 2.

[0021] It should be noted that the pipeline crawling carrier platform 1 is the carrier platform of the entire pipeline anti-corrosion inspection and disposal tool, which is used to place the tool near the pipeline for inspection and disposal, and then carry out the next step of operation. The pipeline crawling carrier platform 1 can be of magnetic adsorption type, or it can be of other types. It can be stably fixed on the pipeline when not moving, which is convenient for subsequent operations. The coating thickness measuring component 3, the grinding and dust collection component 4 and the spraying component 5 can be installed on the transverse drive component 2 at the same time, or they can be installed on the transverse drive component 2 separately and replaceably. After the coating thickness measuring component 3, the grinding and dust collection component 4 and the spraying component 5 are installed on the transverse drive component 2, they can be fixed in position relative to the transverse drive component 2, or they can be retractable, or they can be rotatable. The pipeline anti-corrosion inspection and disposal tool can also be a pipeline robot.

[0022] According to the technical solution provided in the embodiment of the present application, by setting up the pipeline anti-corrosion inspection and disposal tools, mainly including a pipeline crawling and carrying platform 1, a lateral driving component 2 and three tools (i.e., a coating thickness measuring component 3, a grinding and dust suction component 4, and a spraying component 5), the pipeline crawling and carrying platform 1 and the lateral driving component 2 move normally during operation, and can cooperate to transport the coating thickness measuring component 3, the grinding and dust suction component 4 and the spraying component 5 to the designated position of the pipeline for operation, thereby realizing the use of the coating thickness measuring component 3 to measure the surface coating thickness, then using the grinding and dust suction component 4 to grind the coating, and finally using the spraying component 5 to spray the surface.

[0023] In at least one embodiment of the present application, reference Figure 4The transverse drive assembly 2 includes a transverse motor assembly 6, a nut 7, a transverse assembly slide 8, a lead screw 9, a guide rail 10, a first transverse assembly mounting plate 111, a slider 12 and a second transverse assembly mounting plate 213. The transverse motor assembly 6 is a power unit and is fixedly mounted on one side of the guide rail 10. The first transverse assembly mounting plate 111 is fixedly mounted on the other side of the guide rail 10. Both ends of the lead screw 9 are supported on the transverse motor assembly 6 and the first transverse assembly mounting plate 111 through bearings. The output shaft of the transverse motor assembly 6 is fixedly connected to the lead screw 9 to drive the lead screw 9 to rotate. The slider 12 is slidable on the guide rail 10 and forms a linear motion pair with the guide rail 10. The transverse assembly slide 8 is fixedly mounted on the slider 12. The nut 7 is fixedly mounted in the middle of the transverse assembly slide 8, and the nut 7 and the lead screw 9 form a lead screw nut pair. The second transverse assembly mounting plate 213 is fixedly installed on the side of the transverse motor assembly 6, and the other end of the second transverse assembly mounting plate 213 is fixed in front of the pipeline crawling carrier platform 1. The transverse drive assembly 2 is fixedly mounted on the front of the pipeline crawling and carrying platform 1 through the first transverse assembly mounting plate 111 and the second transverse assembly mounting plate 213 on both sides. The coating thickness measuring assembly 3, the grinding and dust collection assembly 4 and the spraying assembly 5 are respectively detachably mounted on the transverse assembly slide 8 of the transverse drive assembly 2. In this way, the transverse motor assembly 6 drives the lead screw 9, thereby driving the transverse assembly slide 8 to move linearly on the guide rail 10.

[0024] It should be noted that the guide rail 10 is the installation base of the transverse drive assembly 2. The number of the sliders 12 can be one or more. For example, there are 4 sliders 12 in total.

[0025] The coating thickness measuring component 3 is used to measure the coating thickness on the pipeline surface. On this basis, the embodiment of the present application does not specifically limit the structural design of the coating thickness measuring component 3.

[0026] For example, in at least one embodiment of the present application, reference Figure 5The coating thickness measuring component 3 includes a guide cylinder 14, a thickness gauge mounting seat 15, a coating thickness gauge main unit 16, a thickness measuring probe 17, a camera 18 and a camera mounting seat 19. The cylinder body of the guide cylinder 14 is fixed on the transverse component slide 8 of the transverse drive component 2. The thickness gauge mounting seat 15 is used to fix the coating thickness gauge main unit 16 and the thickness measuring probe 17, and the thickness gauge mounting seat 15 is installed on the piston block of the guide cylinder 14. The coating thickness gauge main unit 16 is used to display the coating thickness value. The camera 18 is used to observe the coating thickness gauge main unit 16 and the thickness measuring probe 17. The camera 18 is fixed on the camera mounting seat 19, and the camera mounting seat 19 is fixedly mounted on the piston block of the guide cylinder 14. In this way, when working, the thickness measuring probe 17 is pushed against the coating of the pipeline through the telescopic movement of the guide cylinder 14, and the thickness of the coating of the pipeline can be measured when it is pushed out. When the coating thickness measuring assembly 3 is working, after the guide cylinder 14 pushes the thickness measuring probe 17 onto the pipe coating, the coating thickness gauge host 16 can accurately display the coating thickness, and can also be observed through the camera 18. The thickness measuring range includes 0 to 1500 μm, which can meet the requirements of on-site coating detection.

[0027] The grinding and dust collection component 4 is used to grind the coating on the surface of the pipeline that needs to be maintained, and can also collect the dust generated by the grinding. On this basis, the embodiment of the present application does not specifically limit the structural design of the grinding and dust collection component 4.

[0028] For example, in at least one embodiment of the present application, reference Figure 6 The grinding and dust collection component 4 includes a guide cylinder 14, a grinding component mounting seat 20, a grinding and dust collection tool 21, a camera 18 and a camera mounting seat 19. The cylinder body of the guide cylinder 14 is fixed on the transverse component slide seat 8 of the transverse drive component 2. The grinding component mounting seat 20 is fixedly mounted on the piston block of the guide cylinder 14. The grinding and dust collection tool 21 is used for coating grinding and dust collection on the surface of the pipeline, and the grinding and dust collection tool 21 is fixedly mounted on the grinding component mounting seat 20. During grinding, the grinding and dust collection tool 21 is pushed against the pipeline coating by the guide cylinder 14 for grinding. The camera 18 is used to observe the grinding and dust collection tool 21. The camera 18 is fixed on the camera mounting seat 19, and the camera mounting seat 19 is fixedly mounted on the piston block of the guide cylinder 14. In this way, when the grinding and dust collection component 4 is working, the guide cylinder 14 pushes the grinding and dust collection tool 21 against the coating to be polished, starts the grinding and dust collection component 4, and then moves horizontally. The grinding is performed during the movement, and the coating can be effectively polished. The degree of polishing can reach the St2 level, and the dust generated during the grinding process can be automatically absorbed by the grinding and dust collection tool 21. After polishing, the surface of the pipeline can meet the requirements of anti-corrosion treatment, and the dust collection tool can cleanly absorb the dust generated during the grinding process, which can effectively ensure the conditions and cleanliness of the implementation of the pipeline coating in the limited space on site.

[0029] It should be noted that the coating thickness measuring assembly 3 and the grinding dust collecting assembly 4 can share a guide cylinder 14, which is the installation base of the coating thickness measuring assembly 3 and can also be the installation base of the grinding dust collecting assembly 4. The grinding dust collecting tool 21 can be pneumatic or electric.

[0030] The spraying assembly 5 is used to spray the polished pipe surface. On this basis, the present embodiment of the present application does not specifically limit the structural design of the spraying assembly 5. For example, in at least one embodiment of the present application, reference Figure 7 The spray assembly 5 includes a spray assembly mounting seat 22 and a spray gun 23. The spray assembly mounting seat 22 is fixedly mounted on the transverse assembly slide 8 of the transverse drive assembly 2. The spray gun 23 is a nozzle of the spray system, which is fixedly mounted on the spray assembly mounting seat 22, and is used to atomize the paint into small particles, and can adjust the flow rate and density. In this way, when the spray assembly 5 is working, the spray gun 23 can spray the paint and adjust the flow rate. Through the pipeline crawling carrier platform 1 and the transverse drive assembly 2, the coating can be evenly sprayed on the polished pipeline surface. The spraying thickness can achieve 300 to 800 μm, which can fully meet the implementation requirements of the existing coating system process of the power plant.

[0031] At least one embodiment of the present application further provides a pipeline coating inspection and treatment method, which is performed using the pipeline anti-corrosion inspection and treatment tool in the embodiment of the present application. The pipeline coating inspection and treatment method includes the following steps.

[0032] S1: Using the movement of the pipeline crawling and carrying platform 1 and the lateral movement of the lateral driving component 2, the coating thickness measuring component 3 is transported to the designated area for coating thickness measurement.

[0033] Specifically, during operation, the transverse driving component 2 is first installed on the pipeline crawling and transporting platform 1, and the coating thickness measuring component 3 is installed on the transverse component slide 8 of the transverse driving component 2. The pipeline crawling and transporting platform 1 is controlled to transport it to the vicinity of the pipeline to be inspected, and then the coating thickness measuring component 3 is laterally adjusted by controlling the transverse motor component 6.

[0034] For example, the guide cylinder 14 is controlled to push the thickness probe 17 onto the pipeline coating, and the camera 18 is used to observe the reading of the coating thickness gauge host 16. After the thickness measurement is completed, the guide cylinder 14 is controlled to retract the thickness probe 17. In this way, the coating thickness of other positions of the pipeline is sampled. After the inspection is completed, the pipeline crawling and carrying platform 1 is controlled to retract it. After the inspection work is completed, it is determined through analysis which pipeline coatings need to be repaired.

[0035] S2: The grinding and dust collection component 4 is used to grind the coating to be processed.

[0036] For example, the coating thickness measuring component 3 can be replaced with the grinding and dust collection component 4 to grind the coating to be processed. Specifically, the coating thickness measuring component 3 is removed, and the grinding and dust collection component 4 is installed on the lateral component slide 8 of the lateral drive component 2, and the pipeline crawling carrier platform 1 transports it to the vicinity of the pipeline to be polished, and the guide cylinder 14 is controlled to push the grinding and dust collection tool 21 against the coating to be polished, and the grinding and dust collection component 4 is started, and the lateral motor component 6 is controlled to move the grinding and dust collection tool 21 laterally. The moving process can realize the grinding of the coating, and the dust generated during the grinding process can be autonomously absorbed by the grinding and dust collection tool 21. After the lateral movement, the pipeline crawling carrier platform 1 is controlled to step forward a certain distance, and then move laterally, and this method is used until the area to be polished is completed. After the grinding is completed, the grinding and dust collection tool 21 is turned off, and the guide cylinder 14 is controlled to retract the grinding and dust collection tool 21, and then the pipeline crawling carrier platform 1 is controlled to return to the starting position, and the grinding work is completed.

[0037] S3: Finally, the polished pipeline surface is sprayed using the spraying assembly 5 .

[0038] For example, the polishing dust collection component 4 can be replaced with a spraying component 5 to spray the polished pipe surface. Specifically, the polishing dust collection component 4 is removed, and the spraying component 5 is installed on the transverse component slide 8 of the transverse drive component 2, and the pipeline crawling carrier platform 1 transports it to the vicinity of the pipeline that needs to be sprayed. According to the process requirements, the pipeline crawling carrier platform 1 and the transverse drive component 2 are controlled to move the spray gun 23, and the spray gun 23 is turned on at the same time to spray the paint on the polished pipe surface. After spraying, the spray gun 23 is turned off, and the pipeline crawling carrier platform 1 is controlled to return to the starting position. The entire anti-corrosion treatment work is completed.

[0039] According to the pipeline coating inspection and disposal method provided in the embodiment of the present application, the automated coating inspection and disposal of the pipeline can be realized, which has the advantages of efficiency, safety and economy. In terms of efficiency, the pipeline coating inspection and disposal method provided in the embodiment of the present application can save the time of conventional inspection and disposal (including ordinary inspection and disposal device method), and can save more than 30% of the inspection time compared with the existing general inspection and disposal methods of domestic nuclear power, especially the pipeline with a diameter of 700mm in the seawater system. In terms of safety, the seawater pipelines of nuclear power plants are all effective spaces, and some sections of the pipelines are inaccessible pipelines. The existing inspection and disposal methods have certain safety implementation risks. This application can effectively avoid the safety risks brought about by the inspection and coating implementation process. In terms of economy, the existing nuclear power plant seawater pipelines mainly adopt personnel to implement inspection and coating construction, and the cost per square meter is more than 600 yuan. After using this application, the inspection and coating construction costs can be saved by 200 yuan per square meter, and the number of team members is saved, which effectively reduces the cost of extended construction period and material costs caused by the difficulty of personnel to reach. Therefore, compared with the general inspection and disposal methods, the economic advantages are very obvious.

[0040] It should be noted that since the pipeline coating inspection and disposal method is performed using the pipeline anti-corrosion inspection and disposal tool in the embodiment of the present application, it includes the corresponding technical features of the pipeline anti-corrosion inspection and disposal tool in the embodiment of the present application and can achieve the corresponding technical effects, which will not be repeated here.
