Description

Technical Field

[0001] The utility model relates to the technical field of nondestructive testing, in particular to a penetrant testing device for welds of nuclear power radioactive equipment. Background Art

[0002] At present, the penetrant testing work in nuclear power plants mainly focuses on detecting the welds of some components such as pressure pipelines, supports, valves, spare parts, etc., and carrying out preventive, corrective and renovation inspection work on components such as the base metal of mechanical equipment. According to the working principle of penetrant testing: after the surface of the workpiece is coated with a penetrant containing a fluorescent dye or a coloring dye, under the capillary action, after a certain period of time, the penetrant can penetrate into the surface open defects; the excess penetrant on the surface of the workpiece is removed, and after drying, an adsorption medium - developer is applied to the surface of the workpiece; also under the capillary action, the developer will absorb the penetrant in the defects, that is, the penetrant back-permeates into the developer; under a certain light source (black light or white light), the penetrant trace at the defect is displayed (yellow-green fluorescence or bright red), so as to detect the morphology and distribution state of the defect.

[0003] Conventional penetrant testing methods include solvent-removable penetrant testing, which mainly includes steps such as illuminance measurement, pre-cleaning, penetration, solvent removal, imaging, observation and evaluation, and post-cleaning. The existing operations of the above steps are manually performed by personnel with corresponding qualification authorizations. However, due to the radioactivity of the equipment itself and the presence of radioactive dust on the surface of the inspected components in contact with radioactive media, there is a risk of radioactive dust contamination after being removed from the nuclear power unit system. And during the operation of the unit, for some equipment components with the same working conditions and the same types, penetrant testing needs to be performed to judge surface defects, and there is a situation of monitoring a batch of equipment components. Long-term testing requires a large amount of manpower, with low efficiency. At the same time, the time for performing penetrant testing is relatively long, which may lead to the over-standard of the cumulative dose of personnel. Content of the Utility Model

[0032] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0033] Figure 1 Fig. 1 shows a weld penetration inspection device 1 for nuclear power radioactive equipment in an embodiment of the present utility model. The weld penetration inspection device 1 for nuclear power radioactive equipment can be remotely controlled to automatically perform solvent-removable penetrant inspection work to avoid the contamination risk brought by manual inspection.

[0034] The weld penetration inspection device 1 for nuclear power radioactive equipment includes a base 10 and a support conversion mechanism 20, where the base 10 is used to place the component to be inspected. The support conversion mechanism 20 is installed on the base 10 and is used to perform penetration inspection operations on the component to be inspected, and can automatically switch steps, so that all step processes of solvent-removable penetrant inspection work can be implemented one by one through this inspection device.

[0035] Specifically, at least one lighting component is further provided on the support conversion mechanism 20 for performing the illuminance measurement step. The support conversion mechanism 20 includes a support component 21 and a conversion component 22. The support component 21 is installed on the base 10. The conversion component 22 is movably arranged up and down on the support component 21 to facilitate the adjustment of the up and down position, and thus flexibly adapt to components to be inspected with different structures, ensuring that the conversion component 22 can perform inspection operations on components to be inspected with any structure.

[0036] It should be understood that the lighting component can be arranged on the support component 21 and / or the conversion component 22, as long as the illuminance measurement can be achieved.

[0037] The conversion component 22 includes a rotating member 221 and at least two connecting members. The rotating member 221 is rotatably arranged on the support component 21, and the connecting members are arranged on the rotating member 221 to rotate together with the rotating member 221, so as to be as close as possible to the component to be inspected, and adjust the positional relationship between the connecting members and the component to be inspected by rotation, thereby ensuring that the liquids to be sprayed on the component to be inspected in each step can be sprayed on the surface of the component to be inspected.

[0038] Among them, the connecting member is hollow to accommodate an output pipe for transmitting various solvents, so that various solvents that need to be sprayed on the component to be inspected in each step can be sprayed out on the connecting member through the output pipe. A plurality of output holes are further formed on the connecting member for the solvent to spray out. Both ends of the output pipe are respectively communicated with the container and the output pipe, and the container contains the solvent that needs to be sprayed on the component to be inspected. A cleaning cloth assembly 23 is further provided on one of the connecting members for cleaning and wiping the component to be inspected to implement the solvent removal step.

[0039] It should be understood that the number of the output pipes is at least four, which are respectively communicated with four containers (not shown in the figure), and each container contains a different solvent, namely a cleaner, a penetrant, a developer, and a cleaning agent, corresponding to the requirements of each step.

[0040] In some embodiments, the weld penetration inspection device 1 for nuclear power radioactive equipment further includes a control system 30 for remotely controlling the inspection process of the weld penetration inspection device 1 for nuclear power radioactive equipment.

[0041] It should be understood that, for the convenience of description, the control system 30 is shown in the figure as being connected to the operating console 12 and the main body 11, but this does not mean that it must be connected to both. It can be electrically connected to relevant components through cables, and then physically isolated from other components in the nuclear power radioactive equipment weld penetration detection device 1 to avoid radiation damage.

[0042] In some embodiments, the rotating member 221 is rotated by being driven by a motor (not shown in the figure). The motor is electrically connected to the control system, so as to drive the motor to drive the rotating member 221 to rotate under the control of the control system. At the same time, a pump body (not shown in the figure) can be provided on each output pipe for pumping the solvent in the container, and each pump body is also electrically connected to the control system, so as to control the pump bodies on each output pipe respectively through the control system. Through the control of the rotation of the rotating member 221 and the control of the pump bodies by the control system, the conversion between each step is realized.

[0043] In some embodiments, the number of the connecting members can be two or more. When there are two connecting members, one of them is provided with a cleaning cloth assembly 23 for performing the solvent removal step, and at the same time, a cleaning agent for wetting the cleaning cloth is contained in the container connected to the output pipe inside the connecting member. Another connecting member can contain three output pipes at the same time, corresponding to the remaining three containers, which respectively contain a cleaning agent, a developer and a penetrant. The three output pipes are respectively communicated with different output holes (or the same output hole) on the connecting member to realize the three steps of pre-cleaning, penetration and imaging. When performing different steps, different output pipes and containers are operated to output the solvent.

[0044] In some other alternative embodiments, the number of the connecting members can be set to be multiple, and each solvent container corresponds to multiple output pipes which are communicated with the output ports of multiple connecting members to expand the spraying range.

[0045] In this embodiment, the number of the connecting members is four, namely a cleaning agent connecting member 222, a penetrant connecting member 223, a developer connecting member 224 and a cleaning cloth connecting member 225. Referring together Figure 4 to it, a plurality of first output holes 2221 are formed on the cleaning agent connecting member 222. The conversion assembly 22 further includes a first output pipe (not shown in the figure), and both ends of the first output pipe are respectively communicated with the plurality of first output holes 2221 and the container containing the cleaning agent.

[0046] A plurality of second output holes (not shown in the figure) are formed on the penetrant connecting member 223. The conversion assembly 22 further includes a second output pipe (not shown in the figure), and both ends of the second output pipe are respectively communicated with the plurality of second output holes and the container containing the penetrant.

[0047] A plurality of third output holes (not shown in the figure) are formed on the imaging agent connector 224. The conversion assembly 22 further includes a third output pipe (not shown in the figure). Two ends of the third output pipe are respectively communicated with the plurality of third output holes and a container containing the imaging agent.

[0048] Refer to together Figure 5 , a plurality of fourth output holes 2251 are formed on the cleaning cloth connector 225. The conversion assembly 22 further includes a fourth output pipe (not shown in the figure). Two ends of the fourth output pipe are respectively communicated with the plurality of fourth output holes 2251 and a container containing the cleaning agent.

[0049] As Figure 2 shown, in some embodiments, the base 10 includes a body 11 and an operating table 12. A positioning groove 111 is formed on the upper end surface of the body 11 for positioning the plate-shaped component to be measured 2. The operating table 12 is connected to the body 11 and forms a receiving groove (not shown in the figure) for receiving a container containing the solvent.

[0050] Specifically, both the body 11 and the operating table 12 are in a plate shape. In this embodiment, both the body 11 and the operating table 12 are rectangular. The operating table 12 is arranged on one side of the body 11. The body 11 is further provided with protruding limiting portions 113 on both sides of the positioning groove 111 to clamp the plate-shaped component to be measured 2 in the positioning groove 111.

[0051] In some other alternative embodiments, the positioning groove 111 may not be provided, and the positioning effect on the plate-shaped component to be measured 2 can also be achieved by providing a protruding positioning structure (such as a positioning ear block, etc.) on the upper end surface of the body 11.

[0052] In some embodiments, the base 10 further includes at least one guide rail structure 13. The guide rail structure 13 is connected to the body 11 and / or the operating table 12. The support assembly 21 is movably arranged on the base 10 through the guide rail structure 13, so that the conversion assembly 22 located on the support assembly 21 can move relative to the body 11 to expand the coverage range of the conversion assembly 22, so that no matter where the weld is located on the component to be measured, the conversion assembly 22 can reach the position corresponding to the weld through the relative movement of the guide rail structure 13 and the support assembly 21.

[0053] It should be understood that the guide rail structure 13 can be to drive the lifting seat 211 to move through a chute or a motor, or to drive the lifting seat 211 to move through a moving wheel and a motor, or to drive the lifting seat 211 to move through a lead screw, which is not specifically limited here. The driving component in the guide rail structure 13 is electrically connected to the control system to achieve power drive, and then drives the support assembly 21 to move back and forth along the guide rail structure 13.

[0054] In some embodiments, the support assembly 21 includes at least one lifting seat 211 and at least one fixing member 212. The lifting seat 211 can automatically extend and retract for lifting operations. The rotating member 221 is rotatably disposed at the upper end of the lifting seat 211, thereby realizing the up and down movement of the rotating member 221. The fixing member 212 is disposed on the lifting seat 211 and is used for fixing the cylindrical component to be measured 3 (such as Figure 3 as shown), to prevent the cylindrical component to be measured 3 such as a cylinder from moving during the detection process.

[0055] In some embodiments, the lifting seat 211 is driven by a motor to realize automatic lifting. The motor is electrically connected to the control system to remotely drive the lifting of the lifting seat 211 through the control system.

[0056] In some embodiments, the fixing member 212 is in the shape of a telescopic rod and is inserted through the lower end of the lifting seat 211. When detecting the plate-shaped component to be measured 2, it retracts into the lifting seat 211, and when detecting the cylindrical component to be measured 3, it extends out to avoid causing occlusion.

[0057] Specifically, in this embodiment, the fixing member 212 is also driven by a motor to realize telescoping. The motor is electrically connected to the control system. It should be understood that the various motors mentioned above are not the same motor, and it is only an explanation of their driving methods.

[0058] Such as Figure 3 as shown, in this embodiment, the fixing member 212 is arranged in a rod shape, and the number thereof is at least two to ensure the fixation of the cylindrical component to be measured 3, to avoid relative movement in the horizontal direction between the two, and the fixation of the two also needs to ensure that the cylindrical component to be measured 3 can rotate, thereby ensuring that the weld formed on the circumference of the cylindrical component can be comprehensively sprayed / wiped.

[0059] In some embodiments, a plurality of universal wheels 112 are evenly spaced on the upper end surface of the main body 11, so that the cylindrical component to be measured 3 horizontally arranged on the main body 11 can roll under the drive of the universal wheels 112, thereby ensuring that the weld formed on the circumference of the cylindrical component to be measured 3 can rotate through the cylindrical component to be measured 3, so that each position of the weld can correspond to the conversion assembly 22, and the operations of each step can be completed through the conversion assembly 22.

[0060] Specifically, in this embodiment, again such as Figure 1As shown, the universal wheel 112 is disposed on the lower end surface of the groove body of the positioning groove 111 of the main body 11, so that when detecting the plate-shaped component to be measured 2, the plate-shaped component to be measured 2 is limited in the positioning groove 111 and placed on the universal wheel 112. When detecting the cylindrical component to be measured 3, the cylindrical component to be measured 3 is also placed on the universal wheel 112 in the positioning groove 111 and is limited by the fixing member 212.

[0061] It should be understood that the arrangement of the universal wheels 112 on the main body 11 can be arranged in a matrix, can be staggered, or can be arranged in a circumferentially diffused manner, and no specific limitation is made here.

[0062] The universal wheel 112 needs to rotate automatically, and then drive the cylindrical component to be measured 3 to rotate around its axis through the friction with the cylindrical component to be measured 3. The universal wheel 112 is electrically connected to the control system to control the rotation through the control system. The universal wheel 112 can achieve the above effects by adopting the existing technology.

[0063] In this embodiment, the number of the lifting seats 211 and the rotating members 221 is two. The two lifting seats 211 are respectively arranged on both sides of the main body 11. The two rotating members 221 are arranged one-to-one on the two lifting seats 211. The cleaning agent connecting member 222, the penetrant connecting member 223, the developer connecting member 224, and the cleaning cloth connecting member 225 are respectively connected to the two rotating members 221, so as to realize the coverage of the main body 11 in the first direction.

[0064] Specifically, a rotatable rotating shaft 213 is further arranged between the upper end parts of the two lifting seats 211 and is driven to rotate by a motor. The motor is electrically connected to the control system. The two rotating members 221 are respectively fixed to the ends of the rotating shaft 213, so as to realize synchronous rotation.

[0065] In this embodiment, the cleaning agent connecting member 222, the penetrant connecting member 223, the developer connecting member 224, and the cleaning cloth connecting member 225 are all in the shape of a hollow rod. The two ends of each of them are respectively connected to the two rotating members 221, and the connection positions with the two rotating members 221 are such that the cleaning agent connecting member 222, the penetrant connecting member 223, the developer connecting member 224, and the cleaning cloth connecting member 225 are arranged in parallel at intervals, so as to ensure that all of them are parallel to the main body 11.

[0066] In some other alternative embodiments, the cleaning agent connecting member 222 and / or the penetrant connecting member 223 and / or the developer connecting member 224 and / or the cleaning cloth connecting member 225 can also be in other shapes such as a hollow plate shape.

[0067] In some embodiments, the fixing member 212 is rod-shaped and there are four of them. Two are provided on each lifting seat 211. The two fixing members 212 on the same lifting seat 211 are arranged at intervals, and the interval distance can ensure the limitation of the cylindrical component to be measured 3 (it should be understood that only one fixing member 212 is shown on each lifting seat 211 in the figure, but it does not mean that only one fixing member 212 can be provided in this embodiment, and no specific limitation is made here).

[0068] In some other alternative embodiments, three or more fixing members 212 can also be provided on each lifting seat 211, and their arrangement positions can also be flexibly adjusted according to the structure of the cylindrical component to be measured 3. The fixing member 212 can also be in a columnar, plate-like or other structures, as long as it can achieve the limitation of the cylindrical component to be measured 3.

[0069] In this embodiment, the number of the guide rail structures 13 is two, corresponding to the number of the lifting seats 211 and the rotating members 221. One guide rail structure 13 is arranged between the main body 11 and the operating table 12, and the other guide rail structure 13 is located on the side of the main body 11 away from the operating table 12. The two lifting seats 211 are connected to the two guide rail structures 13 and move synchronously through the two guide rail structures 13, so as to realize the coverage of the conversion assembly 22 on the main body 11 in the second direction.

[0070] It should be understood that the first direction is perpendicular to the second direction and is respectively parallel to the two symmetry axes of the main body 11, thus realizing the full coverage of the main body 11, so that no matter where the detection device is installed on the main body 11 and no matter where the weld is located on the device to be measured, it can correspond to the conversion assembly 22, and then the detection operation can be carried out.

[0071] In some embodiments, the lighting component is arranged on the rotating shaft 213 to realize the illuminance measurement step. At least one video terminal (not shown in the figure) is also arranged on the rotating shaft 213, which is used for real-time monitoring of the operation of the nuclear power radioactive equipment weld penetration detection device 1 to ensure the accuracy of the operation. The lighting component and the video terminal are both electrically connected to the control system, and the control system further includes a display module for displaying the real-time data captured by the video terminal.

[0072] In some other alternative embodiments, the lighting component and / or the video terminal can also be arranged on the lifting seat 211, or on each connecting member, or on the rotating member 221.

[0073] In some embodiments, the rotating member 221 is cross-shaped and has four protruding ends to be respectively connected to the ends of the cleaning agent connector 222, the penetrant connector 223, the developer connector 224, and the cleaning cloth connector 225. Two cross-shaped rotating members 221 are arranged correspondingly, and their setting angles are the same, so that the four connectors respectively connected to the two are all parallel to the main body 11.

[0074] For another example Figure 5 As shown, in some embodiments, the cleaning cloth assembly 23 includes a transmission belt 231, two transmission shafts 232, and a cleaning cloth (not shown in the figure). Among them, the two transmission shafts 232 are arranged at both ends of the cleaning cloth connector 225, the transmission belt 231 is sleeved on the two transmission shafts 232, and at least one of the two transmission shafts 232 is electrically connected to the control system and is controlled to rotate by the control system to drive the transmission belt 231 to transmit. The cleaning cloth is detachably sleeved on the transmission belt 231 and then rotates together with the transmission belt 231, so as to be replaced after use.

[0075] It should be understood that referring together to Figure 4 , in this embodiment, the plurality of first output holes 2221 are linearly arranged on the cleaning agent connector 222. In some other optional embodiments, the first output holes 2221 can also be arranged in a matrix or in an alternating and spaced arrangement on the cleaning agent connector 222. The same applies to the second output hole and the third output hole. The setting mode of the fourth output hole 2251 on the cleaning cloth connector 225 is based on being able to wet the cleaning cloth.

[0076] For example, in some embodiments, when the rotating member 221 rotates to the position corresponding to the cleaning cloth connector 225 and the component to be measured, the fourth output hole 2251 can be located in the middle of the transmission belt 231 (cleaning cloth) or above the transmission belt 231 (cleaning cloth), so that the cleaning agent output from the fourth output hole 2251 can flow onto the cleaning cloth according to its own gravity, realizing wetting and infiltration of the cleaning cloth. Specifically, how to arrange above the transmission belt 231 can be flexibly adjusted according to the size and shape of the corresponding position.

[0077] During the specific use process, first, four containers loaded with solvents need to be installed in the accommodating groove, respectively connected to the corresponding four output pipes, a brand-new cleaning cloth is replaced on the cleaning cloth assembly 23, and the component to be measured is installed on the main body 11.

[0078] Here, the cylindrical component 3 to be measured is taken as an example for illustration. First, place the cylindrical component 3 to be measured on the universal wheels 112 of the main body 11, and then control the fixing member 212 to extend through the control system to limit the cylindrical component 3 to be measured. Further, control the guide rail structure 13 through the control system so that the lifting seat 211 moves along it to move to a position corresponding to the weld seam. Then, control the lifting seat 211 through the control system, and further adjust the height position of the conversion assembly 22, and its height is close to the weld seam on the cylindrical component 3 to be measured, so as to facilitate subsequent steps such as spraying and cleaning the weld seam. Complete the installation of the component to be measured and the adjustment of the conversion mechanism 20.

[0079] Further, control the lighting component to turn on the lighting through the control system to perform the illuminance measurement operation.

[0080] Further, after detecting the illuminance value, control the lighting component to turn off through the control system, and control the rotation shaft 213 to rotate through the control system, driving the rotating member 221 and the connecting member provided on the rotating member 221 to rotate, so that the cleaning agent connecting member 222 rotates to a position corresponding to the weld seam.

[0081] Further, control the pump body on the first output pipe to start pumping the cleaning agent through the control system, and at the same time control the universal wheels 112 to rotate, so that the cylindrical component 3 to be measured rotates, and further realize spraying the cleaning agent on the weld seam formed on the circumference of the cylindrical component 3 to be measured, and complete the pre-cleaning step.

[0082] Further, control the rotation shaft 213 to rotate through the control system, driving the rotating member 221 and the connecting member provided on the rotating member 221 to rotate, so that the penetrant connecting member 223 rotates to a position corresponding to the weld seam.
