DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] In the description of the present invention, it should be understood that with respect to the orientation description, such as the orientations or positional relationships indicated by up, down, front, back, left, right, etc., are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0036] An embodiment of the present application discloses a radiation generating device, which is used to facilitate the creation of a radiation environment, thereby facilitating the detection of the radiation alarm performance of radiation detection devices; currently, the radiation sources used to create a radiation environment are usually X-ray sources or γ-ray sources. X-ray sources and γ-ray sources have the same physical nature, but X-ray sources are lighter in weight, more convenient to operate, have better safety, and are more convenient for storage and management than γ-ray sources. Therefore, in the embodiment of the present application, an example is given in which an X-ray source is used to create a radiation environment.

[0037] Referring to Figure 1 , the radiation generating device includes a mounting base 1. A mobile positioning device 2 is provided at the bottom end of the mounting base 1. The mobile positioning device 2 is used to move and fix the mounting base 1. An adjusting device 4 is provided on the mounting base 1. A carrier 3 is provided at the output end of the adjusting device 4. A radiation generating device 5 for emitting an X-ray source to create a radiation environment is provided on the carrier 3. The adjusting device 4 is used to rotate the radiation generating device 5 and adjust the radiation generating device 5 along three axes.

[0038] The radiation generating device 5 can emit an X-ray source to create a radiation environment, and the mobile positioning device 2 can drive the radiation generating device 5 to move to a specified position and fix the radiation generating device 5. In addition, the adjusting device 4 can rotate the radiation generating device 5 and adjust the radiation generating device 5 in three axes, so that the direction of the emitted X-ray source is different, and then a radiation environment with different coverage ranges is created. It should be noted that: the X-ray here will spread divergently from the emission end of the radiation generating device 5, thereby creating a radiation area.

[0039] Referring to Figure 1 , the mobile positioning device 2 includes four universal wheels 21. Four fixing frames 22 are provided at the bottom end of the mounting base 1. A universal wheel 21 is correspondingly arranged on a fixing frame 22. The universal wheel 21 is rotatably connected to the fixing frame 22. A connecting plate 23 is provided on the mounting base 1. A support member 24 is provided on the connecting plate 23. The support member 24 is vertically arranged. The support member 24 is preferably a foot cup. The support member 24 is threadedly connected to the connecting plate 23.

[0040] The radiation generating device can be pushed to a specified position, and then the support member 24 can be rotated to move the support member 24 downward to contact the ground, thereby fixing the radiation generating device.

[0041] Referring to Figure 1 , in order to stably support the mounting base 1, a plurality of connecting plates 23 and support members 24 are provided. The plurality of connecting plates 23 are distributed along the contour of the mounting base 1, and each connecting plate 23 is rotatably connected to the mounting base 1.

[0042] The connecting plate 23 distributed along the contour of the mounting base 1 can be rotated out, and then the support member 24 is rotated to move the support member 24 downward to abut against the ground. The plurality of support members 24 can stably support the mounting base 1.

[0043] Referring to Figure 2, in order to facilitate the stopping of the radiation generating device from moving, the mobile positioning device 2 further includes a braking member 25. The braking member 25 is provided on the fixing frame 22, and the braking member 25 is rotatably connected to the fixing frame 22 in a relatively tight manner. An armrest frame 11 is provided at one end of the mounting base 1 away from the radiation generating device 5, and the braking member 25 is provided at one end of the fixing frame 22 away from the radiation generating device 5.

[0044] Workers can stand on the right side of the armrest frame 11, so as to grasp the armrest frame 11 to push the radiation generating device to the left. When it is necessary to stop the radiation generating device, just rotate the braking member 25 so that the braking member 25 contacts the universal wheel 21, and then the braking member 25 will continuously friction the universal wheel 21 until the universal wheel 21 stops rotating without external force.

[0045] Refer to Figure 2 and Figure 3 , the adjusting device 4 includes a first vertical driving member 41. The first vertical driving member 41 is provided on the mounting base 1. A connecting frame 42 is provided on the output end of the first vertical driving member 41. A second vertical driving member 43 is provided on the connecting frame 42. Since this application needs to be placed in a special temperature and humidity environment, the first vertical driving member 41 and the second vertical driving member 43 are both preferably screw drive mechanisms. The difference between the first vertical driving member 41 and the second vertical driving member 43 is that the first vertical driving member 41 uses a low-precision motor, while the second vertical driving member 43 uses a high-precision motor. By combining rough adjustment and fine adjustment, the position of the radiation generating device 5 in the vertical direction can be quickly adjusted. A first horizontal driving member 44 is provided on the output end of the second vertical driving member 43. A second horizontal driving member 45 is provided on the output end of the first horizontal driving member 44. The movement direction of the output end of the first horizontal driving member 44 is perpendicular to the movement direction of the output end of the second horizontal driving member 45. The first horizontal driving member 44 and the second horizontal driving member 45 are both preferably stainless steel screw drive mechanisms, and both the first horizontal driving member 44 and the second horizontal driving member 45 use high-precision motors. A rotation driving member 46 is provided on the output end of the second horizontal driving member 45. The rotation driving member 46 is preferably a worm and gear drive mechanism. The support bracket 3 is provided on the output end of the rotation driving member 46.

[0046] The first vertical driving member 41, the second vertical driving member 43, the first horizontal driving member 44, the second horizontal driving member 45 and the rotation driving member 46 are all electrically connected to the PLC program controller.

[0047] Refer to Figure 2 and Figure 4, the support bracket 3 includes an upper bracket body 31 and a lower bracket body 32. The lower bracket body 32 is arranged on the output end of the rotation driving member 46, and the upper bracket body 31 is detachably arranged on the lower bracket body 32. Specifically, the upper bracket body 31 is arranged on the lower bracket body 32 through screws. The radiation generating device 5 is arranged between the upper bracket body 31 and the lower bracket body 32, and the radiation generating device 5 is fixed by the mutual clamping of the upper bracket body 31 and the lower bracket body 32.

[0048] The upper bracket body 31 can be disassembled, and then the radiation generating device 5 can be disassembled for maintenance or cleaning.

[0049] Referring to Figure 4 , the radiation generating device 5 is columnar. The radiation generating device 5 includes a tube barrel 51, an X-ray tube 52 for generating X-rays, and a radiator for cooling the X-ray tube 52. The X-ray tube 52 and the radiator are both arranged on the tube barrel 51. The X-ray tube 52 is also connected to a high-voltage generator for providing voltage and current for its operation, and the X-ray tube 52 is also electrically connected to the PLC program controller.

[0050] In order to improve the electrical insulation strength inside the tube barrel 51 and thus ensure the safe operation of the X-ray tube 52, the inside of the tube barrel 51 is sealed, and the tube barrel 51 is filled with SF6 gas. The air pressure inside the tube barrel 51 is preferably filled to 5 bar.

[0051] Referring to Figure 4 , the lower end of the upper bracket body 31 has a first arc surface 311, and the upper end of the lower bracket body 32 has a second arc surface 321. The radiation generating device 5 is fixed by the clamping of the first arc surface 311 and the second arc surface 321.

[0052] Since the radiation generating device 5 is fixed by the clamping of the first arc surface 311 and the second arc surface 321, it is possible to easily disassemble the upper bracket body 31 and then rotate the radiation generating device 5 to adjust the radiation direction emitted by the X-ray tube 52, thereby creating a radiation environment with different coverage ranges.

[0053] Referring to Figure 4 , in order to prevent the radiation detection device from being too far away from the present application, resulting in the area where the radiation detection device is located not meeting the detection requirements, a laser ranging member 6 is arranged on the support bracket 3. The laser ranging member 6 is a prior art and will not be described in detail here. The laser ranging member 6 is used to measure the distance between the radiation detection device and the radiation generating device.

[0054] Referring to Figure 2 and Figure 4 , a camera 7 is also arranged on the support bracket 3. The camera 7 is electrically connected to the PLC program controller. The camera 7 is used to detect whether the ray emitting end of the radiation generating device 5 is aligned with the radiation detection device; a lighting member is also arranged on the support bracket 3, and the lighting member is preferably a lighting lamp.

[0055] The camera 7 can capture the laser spot projected by the laser distance measuring component 6 onto an object. Then, based on the laser spot, it can be determined whether the ray emitted by the ray tube 52 is aligned with the object to be measured. Thus, the ray emitted by the ray tube 52 can be finely adjusted by driving the second vertical driving component 43, the first horizontal driving component 44, the second horizontal driving component 45, and the rotation driving component 46.

[0056] The implementation principle of the radiation generating device in the embodiment of the present application is as follows: First, the present application is pushed to a specified position. Then, the connecting plate 23 is rotated to move the support member 24. After that, the support member 24 is rotated so that the support member 24 moves downward to contact the ground to fix the radiation generating device.

[0057] After that, the laser distance measuring component 6 is driven to detect the distance between the radiation detection device and the present application. According to the detection result of the laser distance measuring component 6, the first vertical driving component 41, the second vertical driving component 43, the first horizontal driving component 44, the second horizontal driving component 45, and the rotation driving component 46 are driven. Then, the camera 7 is driven to capture the laser spot projected by the laser distance measuring component 6 onto an object, and it is judged whether the ray emitted by the ray tube 52 is aligned with the object to be measured. If not, the upper frame 31 is disassembled, and then the direction of the ray tube 52 is adjusted.

[0058] Finally, the ray tube 52 is driven to emit X-rays to create a radiation environment.

[0059] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
