The main task of a spent fuel reprocessing plant is to process the spent fuel produced by a nuclear power plant, recover valuable nuclear materials such as uranium and plutonium, and treat and solidify highly radioactive waste liquid. The annular tank equipment is one of the important equipment in a spent fuel reprocessing plant, and it plays a key role in multiple links. From dissolution, solvent extraction to solidification treatment, each link in a spent fuel reprocessing plant cannot be separated from the support of annular tank equipment. In the future, with the continuous development of spent fuel reprocessing technology, annular tank equipment will continue to play its irreplaceable role.

Therefore, a cleaning method is urgently needed to clean the annular cavity. Summary of the invention

[0028] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 2 -Attached Fig. 9 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Reference Figure 2 The present application provides a network architecture, which includes a cleaning device 100 and a cleaning terminal 200. The cleaning terminal 200 has a built-in cleaning system. The relevant data of the cleaning device 100 can be sent to the cleaning terminal 200, and the cleaning system analyzes and processes the data, and controls the action of the cleaning device 100. The cleaning terminal 200 can be an industrial computer, a smart phone, a computer, etc.

[0030] Reference Figure 3The first embodiment of the present application discloses a cleaning device 100 for an annular groove equipment for nuclear power, including an anode 120, a cathode 110, a DC power supply 130 and an image collector 140.

[0031] Among them, the anode 120 is the cavity of the annular cavity or the device where the annular cavity is located. The cathode 110 is movably arranged in the annular cavity, and the annular cavity is filled with a sulfuric acid mixture, and the sulfuric acid mixture can be proportioned according to actual conditions. The positive electrode of the DC power supply 130 is connected to the anode 120, and the negative electrode is connected to the cathode 110. The image collector 140 can be an endoscope; in this application, the cathode 110 is installed on the endoscope, and the movement of the cathode 110 is achieved by moving the endoscope. The endoscope can be connected to the cleaning terminal 200 for communication to transmit the collected image inside the annular cavity to the cleaning terminal 200, and the cleaning system performs subsequent analysis and processing. In addition, the cleaning device 100 can also include a moving mechanism (not shown in the figure), which is used to drive the movement of the endoscope (including linear movement and rotation). The moving mechanism can be a conventional driving structure, which can be a cylinder + motor structure, or an electric push rod + motor structure, etc. It only needs to realize the movement and rotation of the endoscope, and will not be elaborated here. The moving mechanism is connected to the cleaning terminal 200 for communication and is controlled by the cleaning system.

[0032] Reference Figure 4 The second embodiment of the present application discloses a method for cleaning a ring groove device for nuclear power. As an implementation of the cleaning method, the cleaning method may include S110-S160: S110, obtaining a cleaning position of a part to be cleaned in the annular cavity; S120, adding a sulfuric acid mixed solution into the annular cavity; S130, placing the cathode 110 into the annular cavity; S140, connecting the cathode 110 and the cavity of the annular cavity to a direct current power source 130, and marking the cavity as an anode 120; S150, controlling the cathode 110 to move according to the cleaning position so that the electrolysis position of the cathode 110 matches the cleaning position; S160, regulating the DC power supply 130 to be on or off according to a preset regulation rule.

[0033] Specifically, S110 only needs to be executed before S150, and this application takes S110 as the first step of the process as an example.

[0034] The endoscope can be inserted into the annular cavity manually or by a mobile mechanism. The endoscope collects images of the interior of the annular cavity and transmits the collected images to the cleaning system for analysis. If the cleaning system determines that attachments or spots appear in the image, the cleaning position of the part to be cleaned is determined according to the position of the endoscope at this time. The endoscope is driven to complete an image collection of the entire annular cavity, and the cleaning system counts the number of parts to be cleaned and the corresponding cleaning positions.

[0035] For S120, the sulfuric acid mixed solution can be added into the annular cavity manually, or the volume of the historical sulfuric acid mixed solution or the volume of the direct-generated sulfuric acid mixed solution can be called up according to the size of the annular cavity, thereby controlling the sulfuric acid mixed solution adding device to automatically add it into the annular cavity.

[0036] For S130, the cathode 110 and the endoscope can be independently set and driven into the annular cavity by manual or mobile mechanism; or the cathode 110 can be installed on the endoscope and enter the annular cavity with the endoscope. After the cathode 110 and the cavity of the annular cavity are connected to the DC power supply 130, the cleaning system can control the movement of the cathode 110 according to the cleaning position of the part to be cleaned, so that the electrolysis position of the cathode 110 matches the cleaning position; if the current electrolysis position of the cathode 110 matches the cleaning position of the part to be cleaned, then the movement of the cathode 110 does not need to be controlled at the beginning.

[0037] Reference Figure 5 Specifically, S150 may include S151-S154: S151, determining whether the number of axial parts to be cleaned in the annular cavity is not less than 2; S152, if yes, then divide the annular cavity into a plurality of electrolysis areas according to the size data of the annular cavity, the cleaning position of the part to be cleaned and the corresponding coverage area, and generate a cleaning priority; S153, according to the cleaning priority, controlling the intermittent movement of the cathode 110, wherein the intermittent movement indicates that the cathode 110 needs to complete electrolysis in the current electrolysis area before it can move to the next electrolysis area; S154, if not, control the cathode 110 to move to the cleaning position of the part to be cleaned.

[0038] Specifically, according to the number of parts to be cleaned and the corresponding cleaning positions counted by the cleaning system, it is determined whether the number of parts to be cleaned in the axial direction of the annular cavity is not less than 2. If so, the annular cavity can be divided into multiple electrolysis areas in sequence according to the size data (depth, circumference, radius, etc.) of the annular cavity from shallow to deep, according to the cleaning position of the parts to be cleaned and the corresponding coverage area, and the electrolysis areas are numbered according to natural numbers to generate cleaning priorities, and the shallowest electrolysis area starts electrolysis first. After the electrolysis of the current electrolysis area is completed, the cathode 110 is driven to continue to move to electrolyze the next electrolysis area. If there is only one part to be cleaned in the axial direction, the cathode 110 can be directly driven to that position. Furthermore, if the coverage area of ​​adjacent parts to be cleaned in the axial direction is crossed, the cathode 110 can be driven to between the cleaning positions corresponding to the adjacent parts to be cleaned.

[0039] Reference Figure 6 Specifically for S160: S160 includes S161-S165: S161, obtaining the dimension data of the annular cavity; S162, obtaining the coverage area of ​​the part to be cleaned; S163, searching for matching information from a pre-built historical database according to the size data, the cleaning position of the part to be cleaned, and the corresponding coverage area; S164, if found, retrieve the historical adjustment rules associated with the matching information; S165, adjusting the DC power supply 130 on and off according to the historical adjustment rule; S166, if not found, obtain a comparison value; S167, selecting a minimum alignment value from multiple alignment values; S168, adjusting the DC power supply 130 to be on or off according to the historical adjustment rule corresponding to the minimum comparison value.

[0040] Specifically, the dimension data can be input into the cleaning system by the staff, or the equipment drawings can be uploaded to the cleaning system, and the cleaning system recognizes the drawings to extract the dimension data of the annular cavity. The cleaning system can identify the coverage area of ​​the part to be cleaned by a conventional image recognition algorithm. The historical database is pre-built in the cleaning system according to the historical data, and the matching information can be understood as historical data, including the historical dimension data of the historical annular cavity, and the historical cleaning positions and corresponding historical coverage areas of the historical parts to be cleaned associated with the historical dimension data. The historical dimension data and the historical cleaning positions are in a one-to-many relationship, that is, one historical dimension data can include multiple historical cleaning positions and multiple corresponding historical coverage areas. Each historical data is associated with a historical adjustment rule, and the historical adjustment rule characterizes the power-on time, voltage, and current density of the DC power supply 130.

[0041] If no matching information is found in the historical database, the comparison value m can be obtained, m= ;in, is the i-th historical cleaning position corresponding to the size data, is the historical coverage area corresponding to the i-th historical cleaning position, a is the current cleaning position, and b is the coverage area corresponding to the current cleaning position. For example, if there are 4 historical parts to be cleaned under the size data, there are 4 comparison values ​​m obtained, and then the minimum comparison value is selected from the 4 comparison values ​​m, so as to retrieve the historical adjustment rule associated with the minimum comparison value, and adjust the DC power supply 130 to turn on and off according to the historical adjustment rule.

[0042] Reference Figure 7 Furthermore, after screening the minimum comparison value, S201-S204 may be executed preferentially: S201, determining whether the minimum comparison value is greater than a preset error threshold; S202, if yes, then call the preset basic adjustment rules; S203, regulating the DC power supply 130 on and off according to the basic regulation rule; S204, if not, then adjusting the DC power supply 130 on and off according to the historical adjustment rule corresponding to the minimum comparison value.

[0043] Specifically, the minimum comparison value can be further judged to determine whether the minimum comparison value is greater than an error threshold. The error threshold can be regarded as a correction value of the cleaning system and is set by the background management personnel. If so, the basic adjustment rules preset in the cleaning system can be directly called up to adjust the DC power supply 130 according to the basic adjustment rules. If not, the DC power supply 130 can be adjusted directly according to the historical adjustment rules associated with the minimum comparison value.

[0044] In addition, refer to Figure 8 , after S160, you can also execute S310-S350: S310, after the electrolysis is completed, obtaining final image information of the annular cavity; S320, judging whether the annular cavity is cleaned according to the final image information; S330, if not, locate the part to be cleaned and continue electrolysis until it is clean; S340, recording electrolysis process parameters; S350, updating the electrolysis process parameters into the historical database.

[0045] Specifically, after the electrolysis is completed on all the parts to be cleaned in the annular cavity, the final image information of the annular cavity is obtained through the endoscope, and the final image is identified to determine whether the annular cavity is clean; if not, the endoscope is moved to the unclean part to be cleaned to continue the electrolysis, and the adjustment rule of the DC power supply 130 remains unchanged until the part is clean, and the electrolysis process parameters are recorded to update the electrolysis process parameters to the historical database. The electrolysis process parameters represent the new adjustment rules, thereby enriching the historical database to better cope with the subsequent cleaning of the annular cavity.

[0046] The implementation principle of this embodiment is: The cleaning position of the part to be cleaned in the annular cavity is obtained, and after adding the sulfuric acid mixed solution into the annular cavity, the cathode 110 is placed into the annular cavity, and the cathode 110 and the cavity of the annular cavity are connected to a DC power supply 130, so that according to the cleaning position, the cathode 110 is controlled to move so that the electrolysis position of the cathode 110 matches the cleaning position; then the size data of the annular cavity and the coverage area of ​​the part to be cleaned are obtained, and according to the size data, the cleaning position of the part to be cleaned and the corresponding coverage area, the matching information is searched in the historical database, if found, the historical adjustment rules associated with the matching information are retrieved, and then the DC power supply 130 is adjusted to be on or off according to the historical adjustment rules; after the electrolysis is completed, the final image information of the annular cavity is obtained, and according to the final image information, whether the Panudan annular cavity is cleaned, if not, the unclean part to be cleaned is located, and then the electrolysis is continued until it is cleaned, and the electrolysis process parameters are recorded, so as to update the electrolysis process parameters to the historical database.

Fig. 9 , the cleaning system at least comprises: A cleaning position acquisition module 210 is used to acquire the cleaning position of the part to be cleaned in the annular cavity; The control module 220 is used to control the movement of the cathode 110 according to the cleaning position so that the electrolysis position of the cathode 110 matches the cleaning position; before controlling the movement of the cathode 110, a sulfuric acid mixture is added to the annular cavity, and the cathode 110 is placed in the annular cavity, and the cathode 110 and the cavity of the annular cavity are connected to a DC power supply 130, and the cavity is marked as the anode 120; The regulating module 230 is used to regulate the on and off of the DC power supply 130 according to a preset regulating rule.
