For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The weld detection device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0030] Reference Figure 1 As shown, a weld detection device 100 according to an embodiment of the present invention includes: a support assembly 10 , a ray emitting component 20 , a positioning tool 30 and a ray collecting plate 40 .

[0031] The support assembly 10 is used to connect the tube seat 201 on the container 200, and the support assembly 10 is provided with a movable part 11. The ray emitting member 20 is provided on the movable part 11. The positioning fixture 30 is provided on the side of the container 200 away from the tube seat 201. The ray collecting plate 40 is provided on the positioning fixture 30 to at least obtain the weld image data between the tube seat 201 and the container 200.

[0032] The support assembly 10 is used to support the radiation emitting element 20, which emits radiation, and the radiation penetrates the weld between the tube seat 201 and the container 200. The positioning fixture 30 is used to position the radiation collection plate 40, and the radiation collection plate 40 and the radiation emitting element 20 are located on opposite sides of the weld. The radiation collection plate 40 collects the radiation penetrating the weld, thereby collecting weld image data.

[0033] Nuclear devices are usually equipped with pressure vessels, on which inserted tube sockets are welded. The weld between the pressure vessel and the inserted tube socket is a large curved intersecting line weld. This weld structure plays a vital role in pressure vessels that withstand high temperature, high pressure and radiation environments. Due to the special geometric shape of the weld and the complexity of its working environment, the welding quality of the intersecting line weld needs to be strictly guaranteed, so strict testing and monitoring are required.

[0034] At present, the detection of intersecting line welds in related technologies usually faces certain challenges, mainly in terms of detection accuracy and detection efficiency. Due to the large curved surface and complex intersecting line structure of the weld, traditional detection methods often cannot fully cover every detail of the weld, resulting in insufficient detection accuracy and difficulty in discovering potential minor defects. At the same time, existing detection methods often take a long time to complete the entire detection process, which not only increases the work cost, but may also prolong the downtime of the equipment and affect the normal operation and maintenance of the nuclear device.

[0035] Specifically, the relevant technology uses ultrasonic detection. Due to the curved surface structure of the pressure vessel and the coupling of the wedge, the ultrasonic scanning of the weld can only be performed on the inserted pipe seat, but not on the surface of the container. There is a problem that the scanning cannot cover the area, and there is a risk of missed detection. At the same time, for this type of intersecting line welds, if ultrasonic detection is used, due to the irregularity of the structure and the sound field, there may be deviations in the positioning and quantification of defects, which can easily affect the detection results. The ability requirements for the inspection personnel are also relatively high.

[0036] Alternatively, the related technology uses conventional radiographic film imaging (RT-F), which requires multiple film replenishments, has high radiation protection requirements, and requires darkroom processing. The detection test cycle is long and the efficiency is low, making it difficult to meet production and manufacturing requirements.

[0037] In the embodiment of the present invention, a weld detection device 100 is provided, a ray emitting element 20 is provided on the movable portion 11 of the support assembly 10, a ray collecting plate 40 is provided on the positioning fixture 30, the ray emitting element 20 and the ray collecting plate 40 are respectively provided on opposite sides of the weld, the ray emitting element 20 emits rays to penetrate the weld, and the ray collecting plate 40 collects the rays, thereby obtaining weld image data and realizing a ray digital imaging method. Compared with the ultrasonic scheme in the related art, the risk of missed detection is reduced and the detection accuracy is improved. The ray emitting element 20 is installed on the support assembly 10, and the ray collecting plate 40 is installed on the positioning fixture 30, which reduces the requirements on the ability of the detection personnel. Compared with the conventional ray film imaging method in the related art, there is no need for darkroom processing, the detection test cycle is shortened, and the efficiency is improved.

[0038] Specifically, the ray emitting element 20 may be an X-ray flaw detector or a gamma-ray flaw detector.

[0039] Specifically, a movable portion 11 is provided on the ray emitting member 20, and the movable portion 11 drives the ray emitting member 20 to move, so as to obtain more information of the intersecting line weld of the large curved surface, thereby increasing the detection range and facilitating use.

[0040] More specifically, the movable portion 11 moves according to a preset step requirement, thereby facilitating operation.

[0041] According to the weld detection device 100 of the embodiment of the present invention, by setting the detection device 100, a ray emitting element 20 and a ray collecting plate 40 are set on opposite sides of the weld, the ray emitting element 20 is supported by a support assembly 10, and the ray collecting plate 40 is positioned by a positioning fixture 30. The ray collecting plate 40 collects rays that penetrate the weld and obtains a weld data image, thereby realizing a ray digital imaging method, which improves the detection accuracy while shortening the detection test cycle and improving the efficiency.

The first hole 531 and the second hole 532 are the inlet and outlet of the ventilation channel 52, and the adjustment member 51 is located in the ventilation channel 52. The connecting hole on the adjustment member 51 connects the first hole 531 and the ventilation channel 52, so that the adsorption space 311 is connected with the external space, which can make the air pressure in the adsorption space 311 change to atmospheric pressure, or squeeze the suction cup 312 to discharge the gas in the adsorption space 311, and the blocking part 541 on the adjustment member 51 corresponds to the position of the first hole 531, and the blocking part 541 blocks the first hole 531, thereby disconnecting the connection between the adsorption space 311 and the external space.

[0057] The force of the elastic member 55 acts on the adjusting member 51 , so that the adjusting member 51 automatically moves to block the first hole 531 .

[0058] In the above solution, by providing the adjustment housing 53, the adjustment member 51 and the elastic member 55, the adjustment member 51 is moved to block the first hole 531, which facilitates the operation and improves the convenience.

[0059] Specifically, the elastic member 55 is a spring, and the adjusting member 51 is partially located outside the adjusting shell 53. Pressing the adjusting member 51 overcomes the elastic force of the spring, so that the adjusting member 51 moves, and the connecting hole connects the ventilation channel 52 and the first hole 531. The adjusting member 51 is released, and under the elastic force of the spring, the adjusting member 51 automatically blocks the first hole 531.
