Description

Technical Field

[0001] The present invention relates to the technical field of particle accelerator material irradiation sample holders, and specifically to a modular particle accelerator material irradiation sample fixing device. Background Art

[0002] A multifunctional modular particle accelerator material irradiation sample holder with the publication number of "CN109738288B" in the prior art belongs to the technical field of particle accelerator material irradiation sample holders. It includes a sample base, on which a mechanical tensile module, a mechanical compression and TEM module, an irradiation fluence module, and an irradiation angle module are sequentially arranged in a cross shape. This device improves the accelerator beam utilization efficiency. The sample holder of this device can provide multiple samples for irradiation at one time, saving irradiation experiment time and sample consumption. The present invention organically combines conventional mechanical experiment samples, TEM samples, and samples with changing irradiation conditions, and can obtain a large amount of irradiation sample data at one time, avoiding material irradiation damage differences caused by unstable accelerator beam states during the adjustment and setting of the same parameters, and having higher result consistency.

[0003] However, there are still obvious defects in the use of the above device: Although the above device can adjust the irradiation angle, it cannot independently adjust the irradiation angle. Once the irradiation angle is determined during the irradiation process, it cannot be adjusted. Moreover, the above device can only perform single-sided irradiation and cannot perform more comprehensive irradiation operations; and the above device does not have a corresponding cooling structure. Since metals such as tungsten steel will generate heat during irradiation, and the concentration of heat will be unfavorable for the normal progress of irradiation and will damage the irradiation device and samples, thus being unfavorable for the normal development of subsequent operations. Summary of the Invention

[0004] The purpose of the present invention is to provide a modular particle accelerator material irradiation sample fixing device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A modular particle accelerator material irradiation sample fixing device includes a sample base, on which a sample loading seat is fixedly installed. The sample loading seat is provided with paired flip loading grooves, circular loading grooves, and rectangular loading grooves. In each flip loading groove, a flip frame is rotatably installed through a hollow rotating shaft in a fixed-axis manner. A modular frame bar is detachably installed on the flip frame. The modular frame bar includes a rectangular modular frame bar and a circular modular frame bar;

[0007] A plurality of mutually connected water-cooling liquid storage bins are provided in the sample base and the sample loading base. The water-cooling liquid storage bins are arranged close to the flipping loading groove, the circular loading groove and the rectangular loading groove. The water-cooling liquid storage bins are also communicated with a liquid inlet pipe and a liquid outlet pipe respectively through through holes provided on the side of the sample base. The liquid inlet pipe and the liquid outlet pipe are communicated with an external water-cooling circulation device, and the cooling medium is circulated in the water-cooling liquid storage bin through the external water-cooling circulation device;

[0008] The flipping frame is driven by a flipping mechanism to perform a flipping motion of 0-180°, so as to adjust the irradiation angle and irradiation surface of the sample.

[0009] Preferably, a pair of sealing grooves are provided on the outside of the sample base located outside the sample loading base. Sealing rubber rings are arranged in the sealing grooves. During the irradiation of the sample, internal isolation and sealing are achieved by abutting the edge of the irradiation upper cover against the upper end surface of the sample base.

[0010] Preferably, a storage groove is also provided on the side of the sample base. A storage box is telescopically inserted in the storage groove. A positioning groove is provided in the storage box for accommodating idle modular frame bars.

[0011] Preferably, a water-cooling channel is provided in the flipping frame. The water-cooling channel is communicated with the water-cooling liquid storage bin through a hollow rotating shaft connected thereto. When the external water-cooling circulation device pumps and injects the cooling medium in a cycle, a flow path is formed in the flipping frame, and heat exchange is achieved through contact between the flipping frame and the modular frame bars.

[0012] Preferably, the hollow rotating shafts on both sides of the flipping frame are sleeved in connecting sleeves. The connecting sleeves are fixedly installed in the sample loading base and communicated with the water-cooling liquid storage bin.

[0013] Preferably, magnetic attraction sheets are installed on the sides of the flipping frame and the modular frame bars, and the detachable connection between the flipping frame and the modular frame bars is achieved through the magnetic attraction sheets.

[0014] Preferably, the number of the flipping mechanisms is the same as and corresponds one-to-one with that of the flipping frames. The flipping mechanism includes a pushing piston and a flipping wire groove wheel. The pushing piston is translationally and slidably arranged in a pumping pipe opened in the sample loading seat. The pumping pipe communicates with an external pumping pipe through channels opened in the sample loading seat and the sample base. The external pumping pipe is communicated with an external metering pump. By pumping a quantitative fluid medium into or out of the pumping pipe through the external metering pump, the pushing piston is reciprocally translated and slid. A torsion spring that pushes the flipping frame to be in a horizontal initial state without external force is also sleeved on the hollow rotating shaft. The flipping wire groove wheel is coaxially and fixedly connected with the hollow rotating shaft. A traction rope is wound around the flipping wire groove wheel. One end of the traction rope away from the flipping wire groove wheel is fixedly connected with the pushing piston. During the translational sliding process of the pushing piston, the traction rope is pulled to overcome the elastic force of the torsion spring, so as to cause the flipping frame to perform a fixed-axis flipping motion.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The present invention can adjust the irradiation angle as needed during the irradiation process, and can also adjust the irradiation surface by flipping. Compared with the existing devices, the angle adjustment is more flexible and convenient. At the same time, the present invention is internally provided with a water-cooling liquid storage bin, and the sample loading seat and the samples installed therein can be cooled through the water-cooling liquid storage bin, so as to ensure the normal progress of irradiation and subsequent work.

Detailed implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0025] Embodiment 1:

[0026] A modular particle accelerator material irradiation sample fixing device includes a sample base 1, a sample loading base 2 is fixedly installed on the sample base 1, and paired turning loading grooves 3, circular loading grooves 4 and rectangular loading grooves 5 are formed on the sample loading base 2. In each of the turning loading grooves 3, a turning frame 7 is rotatably installed about a fixed axis through a hollow rotating shaft 6, and a modular frame bar 8 is detachably installed on the turning frame 7. The modular frame bar 8 includes a rectangular modular frame bar 9 and a circular modular frame bar 10;

[0027] A plurality of mutually connected water-cooling liquid storage bins 11 are formed in the sample base 1 and the sample loading base 2. The water-cooling liquid storage bins 11 are arranged close to the turning loading grooves 3, circular loading grooves 4 and rectangular loading grooves 5. The water-cooling liquid storage bins 11 are also respectively communicated with a liquid inlet pipe 12 and a liquid outlet pipe 13 through through holes formed on the side of the sample base 1. The liquid inlet pipe 12 and the liquid outlet pipe 13 are communicated with an external water-cooling circulation device, and the cooling medium circulates in the water-cooling liquid storage bins 11 through the external water-cooling circulation device;

[0028] The turning frame 7 makes a turning motion of 0-180° under the drive of a turning mechanism, so as to adjust the irradiation angle and irradiation surface of the sample.

[0029] In this embodiment, the sample base 1 and the sample loading seat 2 serve as the main structures of the device. A flipping loading groove 3, a circular loading groove 4, and a rectangular loading groove 5 are provided thereon. The circular loading groove 4 and the rectangular loading groove 5 are used for loading fixed samples. A flipping frame 7 is rotatably mounted on the flipping loading groove 3 by a fixed axis. A modular frame strip 8 is detachably mounted on the flipping frame 7. The modular frame strip 8 includes a rectangular modular frame strip 9 and a circular modular frame strip 10. The corresponding modular frame strip 8 can be selected according to the shape requirements of the sample. The modular frame strip 8 is a two-sided through structure, and the sample is clamped and fixed by the frame of the modular frame strip 8. The flipping frame 7 changes the irradiation angle and irradiation surface of the sample through flipping movement, so as to irradiate the sample more comprehensively. In addition, existing structures such as tungsten and steel will generate heat during the irradiation process. If the heat is not dissipated in time, it will damage the irradiation device and the sample, which is not conducive to the normal development of subsequent operations. Therefore, in this embodiment, a water-cooled liquid storage bin 11 is further provided in the sample loading seat 2, and the sample loading seat 2 and the sample are cooled by an external water-cooled circulation device to prevent the concentration of heat and ensure the normal progress of irradiation and subsequent steps.

[0030] Embodiment Two:

[0031] A pair of sealing grooves 14 are further provided on the outside of the sample base 1 located on the outside of the sample loading seat 2. A sealing rubber ring 15 is arranged in the sealing grooves 14. During the irradiation of the sample, the edge of the irradiation upper cover is abutted against the upper end surface of the sample base 1 to achieve internal isolation and sealing.

[0032] In this embodiment, it is further disclosed that the sample base 1 has a structure of a sealing groove 14 and a sealing rubber ring 15, so that during irradiation, the sample loading seat 2 and the sample are isolated from the external environment through the sealing rubber ring 15, thus ensuring the normal progress of internal irradiation.

[0033] Embodiment Three:

[0034] A storage groove 16 is further provided on the side of the sample base 1. A storage box 17 is telescopically inserted into the storage groove 16. A positioning groove 18 is provided in the storage box 17, and the positioning groove 18 is used to accommodate the idle modular frame strip 8.

[0035] In this embodiment, it is further disclosed a storage mechanism for the idle modular frame strip 8. The required modular frame strip 8 is taken off by pulling out the storage box 17 and loaded onto the flipping frame 7.

[0036] Embodiment Four:

[0037] A water-cooling channel is provided inside the flipping frame 7. The water-cooling channel is connected to the water-cooling liquid storage bin 11 through a hollow rotating shaft 6 connected thereto. When the external water-cooling circulation device pumps and circulates the cooling medium, a flow path is formed inside the flipping frame 7. The flipping frame 7 achieves heat exchange by contacting the modular frame strip 8.

[0038] The hollow rotating shafts 6 on both sides of the flipping frame 7 are sleeved inside the connecting sleeve 19. The connecting sleeve 19 is fixedly installed in the sample loading seat 2 and is connected to the water-cooling liquid storage bin 11.

[0039] Magnetic attraction sheets 20 are installed on the sides of the flipping frame 7 and the modular frame strip 8. The detachable connection between the flipping frame 7 and the modular frame strip 8 is achieved through the magnetic attraction sheets 20.

[0040] In this embodiment, a water-cooling channel is further provided inside the flipping frame 7, and the external water-cooling circulation device is used to promote the formation of a flow path inside the flipping frame 7, so as to achieve heat exchange through the contact between the flipping frame 7 and the modular frame strip 8, and finally transfer the heat on the modular frame strip 8. The significance of this operation is that it can not only complete the cooling of the circular loading groove 4 and the rectangular loading groove 5, but also effectively cool the samples loaded on the flipping frame 7. And the cooling medium enters the hollow rotating shaft 6 through the connecting sleeve 19 and finally enters the water-cooling channel inside the flipping frame 7. The significance of this setting is that the hollow rotating shaft 6 not only serves as a fixed-axis rotation mechanism, but also serves as a transition channel for the cooling medium. The detachable connection between the flipping frame 7 and the modular frame strip 8 is achieved through the magnetic attraction sheets 20.

[0041] Embodiment Five:

[0042] The number of flipping mechanisms is the same as and corresponds one-to-one with that of the flipping frames 7. The flipping mechanism includes a pushing piston 21 and a flipping wire groove wheel 22. The pushing piston 21 is slidably arranged in a pumping pipe 23 provided in the sample loading seat 2. The pumping pipe 23 is connected to an external pumping pipe 24 through channels provided in the sample loading seat 2 and the sample base 1. The external pumping pipe 24 is connected to an external metering pump. By pumping or pumping out a quantitative fluid medium into the pumping pipe 23 through the external metering pump, the pushing piston 21 is caused to reciprocate translationally. A torsion spring 25 that pushes the flipping frame 7 to be in a horizontal initial state without external force is also sleeved on the hollow rotating shaft 6. The flipping wire groove wheel 22 is fixedly connected coaxially with the hollow rotating shaft 6. A traction rope 26 is wound around the flipping wire groove wheel 22. One end of the traction rope 26 away from the flipping wire groove wheel 22 is fixedly connected to the pushing piston 21. When the pushing piston 21 translates and slides, it pulls the traction rope 26 to overcome the elastic force of the torsion spring 25 and cause the flipping frame 7 to perform a fixed-axis flipping motion.

[0043] In this embodiment, the specific structure of the flipping mechanism is further disclosed. A built-in metering pump is used to pump the flowing medium in the built-in pump injection pipe 24 at regular intervals and in a fixed quantity. The liquid enters the pump injection pipe 23, thereby pushing the pushing piston 21 to perform a telescopic motion. During the telescopic process of the pushing piston 21, the flipping wire groove wheel 22 is pulled by the traction rope 26 to rotate, thereby adjusting the adjustment angle of the flipping frame 7. Since the built-in metering pump can accurately pump the fluid medium, the flipping angle of the flipping frame 7 can be accurately controlled, so that the irradiation angle and the irradiation surface can be adjusted during the irradiation process.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
