[0002] During the electron beam irradiation process, when the electron beam hits the irradiated object or the inner wall of the channel, x-rays that are harmful to the human body will be generated in the irradiated area.

[0020] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0021] The embodiment of the present invention provides a multifunctional electron beam irradiation experimental device, such as Figure 1-4 As shown, it includes a plate shielding assembly 1 and a coil shielding assembly 2 located above the plate shielding assembly 1. The plate shielding assembly 1 includes a plate conveying assembly and a plate shielding cover arranged on the outside of the plate conveying assembly. The plate conveying assembly can extend in a straight line and is used to convey a plate-like substrate. The plate shielding cover is made of shielding materials such as lead, and the plate conveying assembly is covered inside to play a shielding role. A plate irradiation area is provided in the plate shielding cover, and a first opening 201 is provided on the top of the plate shielding cover above the plate irradiation area. When the plate moves on the plate conveying assembly, it will pass through the plate irradiation area. The electron beam can be injected into the plate irradiation area from the first opening 201 to perform electron beam irradiation on the plate in the plate irradiation area. In order to facilitate the observation of the internal structure, Figure 1 and Figure 2 The sheet material shielding component 1 and the coil material shielding component 2 are both drawn using a partial perspective method.

[0022] The coil shielding assembly 2 includes a coil conveying assembly and a coil shielding cover arranged outside the coil conveying assembly. The coil conveying assembly is used to convey the coil, and the coil shielding cover is made of shielding materials such as lead to play a shielding role. A coil irradiation area is arranged in the coil shielding cover, and a second opening 202 communicating with the coil irradiation area is arranged on the side wall of the coil shielding cover close to the electron accelerator assembly 4. The coil moves with the coil conveying assembly and passes through the coil irradiation area. The electron beam can be injected into the coil irradiation area from the second opening 202 to irradiate the coil in the coil irradiation area with the electron beam.

[0023] A movable guide rail extending along the sheet conveying direction is also provided on the outer side of the sheet shielding assembly 1, and a base 3 is slidably provided on the movable guide rail, and the base 3 is connected to a movable driving assembly, and the movable driving assembly drives the base 3 to move laterally along the movable guide rail. An electron accelerator assembly 4 is rotatably connected to the base 3, and the electron accelerator assembly 4 can rotate relative to the base 3. The electron accelerator assembly 4 is also connected to a rotating driving assembly 41 for driving the electron accelerator assembly 4 to rotate, and the rotating driving assembly 41 can drive the electron accelerator assembly 4 to rotate to different positions. The electron accelerator assembly 4 includes an electron accelerator 42, a nitrogen gas charging pipe 44, a water cooling pipe, an accelerator support structure and an accelerator shielding cover 46 on the outer side, and a cavity is formed in the accelerator shielding cover 46, and the electron accelerator 42 is arranged in the cavity. The bottom of the accelerator shielding cover 46 is provided with a socket 40 for electron beam emission, and the socket 40 can rotate with the electron accelerator assembly 4 to its direction corresponding to the direction of the first opening 201 and the second opening 202 respectively. The outlet of the nitrogen filling pipe 44 can be set at the socket 40 to fill nitrogen into the cavity to maintain a low oxygen environment in the cavity. The water cooling pipe provides cooling water to the accelerator for heat dissipation.

[0024] The multifunctional electron beam irradiation experimental device of this embodiment has two modes: plate irradiation mode and coil irradiation mode. The mobile drive assembly and the rotation drive assembly 41 can coordinate and cooperate to change the position and orientation angle of the electron accelerator assembly 4. In the plate irradiation mode, the socket 40 is docked with the first opening 201, so that the plate is irradiated with electron beams. In the coil irradiation mode, the socket 40 is docked with the second opening 202, so that the coil is irradiated with electron beams.

[0025] In order to ensure the stability of docking, a locking member 47 may be provided on the outer wall of the accelerator shield 46. The locking member 47 is located outside the socket 40. A first matching member is provided outside the first opening 201, and a second matching member is provided outside the second opening 202. When the socket 40 is docked with the first opening 201, the locking member 47 is locked and matched with the first matching member, so that the socket 40 and the first opening 201 are stably docked. When the socket 40 and the second opening 202 are docked, the locking member 47 is locked and matched with the second matching member, so that the socket 40 and the second opening 202 are stably docked.

[0026] The above-mentioned mobile drive assembly and rotation drive assembly 41 can both be connected to the controller. The controller is also connected to a switching button. The user can operate the switching button, and the controller controls the mobile drive assembly and the rotation drive assembly 41 to coordinate actions, and freely switch between the plate irradiation mode and the coil irradiation mode to realize an automated control process. When switching from the coil irradiation mode to the plate irradiation mode, first release the locking fit between the locking member 47 and the second matching member, and the controller controls the mobile drive assembly to move the base 3 away from the coil shielding assembly 2, and the socket 40 is separated from the second opening 202 until it moves to the designated position on the side of the first opening 201. At this time, the rotation drive assembly 41 starts to move, and the electron accelerator assembly 4 gradually rotates to the top of the first opening 201 and gradually approaches the first opening 40, finally realizing the docking of the socket 40 and the first opening 201, and then the locking member 47 is locked with the first matching member to ensure that the docking is tight, forming as shown in the figure. Figure 1 After confirming that the plate shielding assembly 1 and the electron accelerator assembly 4 are well connected and the plate shielding assembly 1 and the electron accelerator assembly 4 are inflated to the target concentration through the nitrogen inflation pipe 44, the plate irradiation operation can be carried out.

[0027] When switching from the plate irradiation mode to the coil irradiation mode, first release the locking fit between the locking member 47 and the first matching member, and the controller controls the rotation drive assembly to drive the electron accelerator assembly 4 to rotate, gradually away from the first opening 201, and the socket 40 will separate from the first opening 201 until the electron accelerator assembly 4 moves to the direction of its socket 40 and the direction of the second opening 202 are parallel and opposite. At this time, the mobile drive assembly starts to move, and the electron accelerator assembly 4 gradually approaches the coil shielding assembly 2, and finally realizes the docking of the socket 40 and the second opening 202, and then the locking member 47 is locked and matched with the second matching member to ensure that the docking is tight, forming a Figure 2 After confirming that the coil shielding assembly 2 and the electron accelerator assembly 4 are well connected and the coil shielding assembly 2 and the electron accelerator assembly 4 are inflated to the target concentration through the nitrogen inflation pipe 44, the coil irradiation operation can be carried out.

[0028] In order to ensure the shielding effect of the connection between the two openings and the socket 40, an embodiment will be provided to specifically describe the structure of the connection. Figure 3 and Figure 4 As shown ( Figure 3 and Figure 4Taking the first interface 201 as an example, the first opening 201 and the second opening 202 are both connected to a connecting pipe 203, and the connecting pipe 203 protrudes from the outer wall of the shielding cover. The socket 40 is connected to a sleeve 401 extending downward, and an annular groove 402 is provided on the end surface of the sleeve 401 extending outward. The size of the annular groove 402 matches the size of the connecting pipe 203. The connecting pipe 203 is configured to be detachably plugged into the annular groove 402 to achieve docking between the socket 40 and the two openings. The connecting pipe 203 and the sleeve 401 are both made of shielding materials, and the cooperation of the annular groove 402 and the connecting pipe 203 forms a labyrinth structure to ensure the shielding effect.

[0029] After the connecting tube 203 is inserted into the annular groove 402, the connecting tube 203 is completely inserted into the annular groove 402, and the top of the connecting tube 203 can be against the inner wall of the annular groove 402. A sealing gasket 403 is also fixed on the end face of the sleeve 401. After the connecting tube 203 is inserted into the annular groove 402, the sealing gasket 403 seals between the sleeve 401 and the outer wall of the shielding cover to prevent external air from entering and maintain the nitrogen protective atmosphere in the shielding structure.

[0030] like Figure 3 and Figure 4 As shown, the width of the annular groove 402 is configured to be greater than a certain value of the thickness of the connecting tube 203. Since the electron accelerator assembly 4 realizes the docking of the socket 40 and the first opening 201 during the rotation process, and the insertion process is a rotating oblique insertion, the annular groove 402 reserves sufficient space to facilitate the smooth insertion of the connecting tube 203 into the annular groove 402. This reserved space can compensate for the shielding defect through the labyrinth structure formed by the cooperation of the annular groove 402 and the connecting tube 203, so the shielding effect can be effectively guaranteed.

[0031] A specific embodiment will be provided for the above-mentioned locking member 47 and the matching member. Figure 3 and Figure 4 As shown, the locking member 47 is a plurality of spring latches arranged on the outside of the sleeve 401. The spring latches penetrate the sleeve 401 and extend into the inside of the sleeve 401. The spring latches can move along the radial direction of the sleeve. The first matching member and the second matching member are latch holes on the outer wall of the connecting tube 203 provided at the first opening 201 and the second opening 202, respectively. The positions and numbers of the latch holes match the spring latches. The distance from the inner end of the spring latch to the axis of the sleeve 401 is slightly smaller than the outer diameter of the connecting tube 203. The inner end of the spring latch can be set to an arc shape. When the sleeve 401 is docked with the connecting tube 203, the connecting tube 203 pushes the spring latch outward first. When the sleeve 401 and the connecting tube 203 are docked in place, the spring latch will be inserted into the latch hole, thereby locking and fixing the sleeve 401 and the connecting tube 203.

[0032] In one embodiment, if Figure 1 and Figure 2 As shown, two movable guide rails are provided, and are respectively arranged on both sides of the sheet shielding cover along the sheet conveying direction, and the base 3 includes two fixed plates 32 located on both sides of the sheet shielding cover, and the two fixed plates 32 are respectively connected with the guide rails. As shown in the figure, the guide rail is a guide rail groove provided on the outside of the sheet shielding cover, and a roller 13 is provided on the inside of the fixed plate 32. The roller 13 can rotate in the guide rail groove, so that the base 3 can move along the sheet conveying direction, and the corresponding movable driving component includes a motor fixed on the outer side of the fixed plate 32, and the output shaft of the motor is connected to the roller 13 to directly move the roller 13 to rotate.

[0033] The electron accelerator assembly 4 is disposed between the two fixed plates 32 and is rotatably connected to the two fixed plates 32 respectively. A rotating shaft 31 is fixed to the electron accelerator assembly 4. Both ends of the rotating shaft 31 are rotatably connected to the two fixed plates 32 respectively. The rotating drive assembly 41 drives the electron accelerator assembly 4 to rotate around the rotating shaft 31 as the center.

[0034] An arc groove 30 is provided on the fixed plate 32, and the arc groove 30 takes the axis center of the rotating shaft 31 as the circle center. A plug rod is fixed on the electron accelerator assembly 4, and the two ends of the plug rod are respectively inserted into the arc grooves 30 of the two fixed plates 32. The rotation driving assembly 41 drives the plug rod to move along the arc groove 30. Since the plug rod only moves in the arc groove 30, the rotation of the electron accelerator assembly 4 is guided by the arc groove 30 to ensure the accuracy of the rotation process.

[0035] Generally speaking, for electron beam irradiation of a plate, the irradiation direction is vertical, and the orientation of the first opening 201 is vertical. For electron beam irradiation of a coil, the irradiation direction is horizontal, and the orientation of the second opening 202 is horizontal. Therefore, the arc groove 30 has an amplitude angle of at least 90 degrees, ensuring that the electron accelerator assembly 4 can be rotated to the orientation of its socket 40 in the horizontal or vertical direction.

[0036] Furthermore, a latching tooth is provided on the inner wall of the arc groove 30, and gears 42 meshing with the latching tooth are provided at both ends of the plug rod. The plug rod is rotatably connected to the electron accelerator assembly 4. A rotation driver and a power transmission mechanism connecting the rotation driver and the plug rod are fixed on the electron accelerator assembly 4. The rotation driver transmits the driving force to the plug rod through the power transmission mechanism, thereby driving the plug rod to rotate, and the gear 42 meshes with the latching tooth, driving the plug rod to move along the arc groove 30. As shown in the figure, the rotation driver can be a motor, and the power transmission mechanism can be a gear set. The output shaft of the motor and the plug rod are respectively connected to the gear set to transmit power. As shown in the figure, the output shaft of the motor and the plug rod are arranged in a vertical position relationship, so the gear set can be a bevel gear.

[0037] In one embodiment, the structure of the plate shielding assembly 1 will be described in detail. The plate shielding cover can be a square cylindrical structure, one end of which can be closed, and the other end is provided with a plate inlet and outlet 5, and a beam absorption plate 12 is also provided in the plate irradiation area. The beam absorption plate 12 is located below the plate conveying assembly, and the beam absorption plate 12 is a water-cooled plate, which is mainly used for heat dissipation.

[0038] The sheet conveying assembly includes a track arranged on the inner wall of the sheet shielding cover, and the track extends along the conveying direction of the sheet. The pallet 51 is slidably arranged on the track and is connected to a driver, which can drive the pallet 51 to move along the track. A sheet entrance and exit is provided at the top of the sheet entrance and exit end 5, and the sheet entrance and exit cover is covered with a movable cover 52 that can open or close the sheet entrance and exit. When preparing for sheet irradiation, open the movable cover 52, place the sheet on the pallet 51, and the driver drives the pallet 51 to move to the sheet irradiation area. After the sheet is irradiated, the driver can drive the pallet 51 to move to the position of the sheet entrance and exit, open the movable cover 52, and take out the irradiated sheet.

[0039] In another embodiment, an opening may be provided at both ends of the sheet shielding cover 1, one opening being a sheet entrance and the other opening being a sheet exit, and the sheet irradiation area is located in the middle of the sheet shielding cover 1. Shielding measures such as a labyrinth shielding structure may be provided in the sheet shielding cover, thereby realizing continuous production of sheets.

[0040] In one embodiment, if Figure 3 and Figure 4 As shown, a labyrinth passage 43 is provided on the top of the accelerator shielding cover 46, and a nitrogen filling pipe 44, a water cooling pipe and an auxiliary cable 45 of the accelerator are all connected to external equipment through the labyrinth passage 43. The labyrinth passage can effectively reduce radiation leakage and nitrogen leakage.

[0041] In one embodiment, the structure of the coil shielding assembly 2 will be described in detail. Figure 1 As shown, the coil conveying assembly includes a guide roller 22 and a water-cooled roller 23. The surface of the coil shielding cover is provided with a coil inlet 25 and a coil outlet 26. Two guide rollers 22 are provided, which are respectively close to the coil inlet 25 and the coil outlet 26. The water-cooled roller 23 is connected to a water-cooled roller driver 24 for driving the water-cooled roller 23 to rotate. The coil 100 enters from the coil inlet 25, passes through a guide roller 22, is sleeved on the water-cooled roller 23, passes through another guide roller 22, and is finally output from the coil outlet 26. After the electron beam passes through the second opening 202, the coil 100 on the water-cooled roller 23 is irradiated with an electron beam.

[0042] The above-mentioned coil shielding cover is a box structure composed of multiple shielding plates, which may include a top plate, a bottom plate and four side plates made of shielding material. A shielding plate on the front of the coil shielding cover is configured to be detachable, that is, the front shielding plate 27 can be separated from the box structure, and the coil inlet 25 and the coil outlet 26 are arranged on the front shielding plate 27. Since the front shielding plate 27 can be separated, it is convenient to pass the coil 100 through the guide roller 22 and the water-cooled roller 23 for loading and assembly. After switching to the coil irradiation mode, the coil 100 needs to be assembled in place before the coil irradiation operation can be started.

[0043] The above contents are further detailed descriptions of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention.
