At present, the ray application technology based on radiation sources has been widely used in the fields of industry, agriculture, medicine, resources, environment, military, scientific research, etc.

[0003] The rays emitted by the radiation source have a certain amount of energy, which can damage cell tissues and thus cause harm to the human body; when a person is irradiated by a large amount of rays, symptoms such as dizziness, fatigue, loss of appetite, nausea, vomiting, etc. may occur, and in severe cases, it may lead to body damage and even death; but when a person is only irradiated by a small amount of rays, generally there will be no discomfort symptoms and no harm to the body. Therefore, radiation sources must be strictly controlled and managed.

[0017] It is further defined that in the above-mentioned radiation source control device, the drive control assembly comprises a screw disposed on a mounting base, a slide table threadably connected to the screw, and a power unit for driving the screw to rotate;

[0018] The slide is slidably connected to the mounting base in the axial direction of the screw rod, and the traction member is fixedly connected to the slide at one end close to the drive control assembly;

[0019] Wherein, when the slide moves along the axial direction of the screw rod, it can synchronously drive the traction member to move relative to the shielding member.

[0022] It is further defined that, in the above-mentioned radiation source control device, the drive control component also includes a sensing component for sensing the relative position state of the traction component and the shielding component.

[0023] It is further defined that, in the above-mentioned radiation source control device, the sensing component includes a trigger member fixedly arranged on the slide table and a plurality of sensing switches fixedly arranged on the mounting base;

[0024] Wherein, a plurality of the inductive switches are arranged at intervals along the axial direction of the lead screw, and can be coupled with the trigger member to adjust the working state of the power unit respectively;

[0025] At least one of the inductive switches is configured such that the radiation source is located inside the shielding member when coupled with the trigger member, and at least one of the inductive switches is configured such that the radiation source is located outside the shielding member when coupled with the trigger member.

[0026] Further defined, for a radioactive source control device as described above, wherein the guiding hole has a bent section, the traction member is specifically arranged as a flexible member, and one end far away from the drive control assembly is elastically slidably arranged in the guiding hole;

[0027] Wherein, in the shielding state, the radioactive source is located inside the shielding member, and one end of the traction member far away from the drive control assembly has a tendency to move the radioactive source to the outside of the shielding member under the action of its own elastic force;

[0034] 2. Since the shielding member is cylindrical and the part of the guiding sleeve penetrating the shielding member is coaxial with the shielding member, when the radioactive source moves to the corresponding position of the shielding member in the guiding hole, the shielding member can provide a uniform shielding effect for the radioactive source in the radial direction of the guiding sleeve, thereby further improving the shielding stability;

Detailed Embodiments

[0043] Next, the technical solutions in the embodiments of the present application will be clearly described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] The radiation source control device provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0046] like Figures 1 to 5 As shown, an embodiment of the present application provides a radiation source control device, including a mounting base 100 and a guide shielding component and a drive control component fixedly disposed on the mounting base 100 .

[0047] The guide shielding assembly includes a shielding member 600 fixedly disposed on the mounting base 100 and a guide sleeve 500 penetrating the shielding member 600 . A guide hole 510 is disposed in the guide sleeve 500 . A traction member 400 is slidably disposed in the guide hole 510 along the extension direction.

[0048] The end of the guide sleeve 500 away from the driving control component extends to the outside of the shielding component 600, or is flush with the end of the shielding component 600 away from the driving control component.

[0049] The guide hole 510 is provided with a first opening at one end of the guide sleeve 500 close to the guide shielding assembly. One end of the traction member 400 is connected to the drive control assembly, and the other end extends from the first opening into the guide hole 510 and is used to install the radiation source 900. The drive control assembly can apply a force to the traction member 400 to move the radiation source 900 to the inside or outside of the shielding member 600.

[0050] It can be understood that, in the shielding state, the driving control component drives the traction member 400 to slide in the guide hole 510 until the radiation source 900 is just located at the corresponding position of the shielding member 600. At this time, the radiation of the radiation source 900 can be shielded by the shielding member 600; in the sample delivery state, the driving control component drives the radiation source 900 to move to the outside of the shielding member 600, thereby performing the irradiation operation of the radiation source 900.

[0051] In an embodiment of the present application, by using the above-mentioned radioactive source control device, the radioactive source 900 is fixedly arranged on the traction member 400, and at the same time, the guide hole 510 is at least partially placed inside the shielding member 600. When the drive control assembly adjusts the relative position of the traction member 400 within the guide hole 510, the position switching of the radioactive source 900 inside and outside the shielding member 600 can be realized, so as to realize the switching between the shielding state and the sample feeding state of the radioactive source 900. This not only has flexible operation, but also can ensure the shielding effect and reliability of the radioactive source 900.

[0052] It can be understood that the shielding member 600 is set to fully cover or semi-cover the guide sleeve 500, which can adapt to radioactive sources 900 of different types or different shielding requirements. Specifically, when the end of the guide sleeve 500 far from the drive control assembly extends outside the shielding member 600, the part of the guide sleeve 500 extending outside the shielding member 600 can be used as the irradiation area; when the end of the guide sleeve 500 far from the drive control assembly is set to be flush with the corresponding end of the shielding member 600, the drive control assembly can drive the radioactive source 900 to move outside the shielding member 600, and the radioactive source 900 located outside the shielding member 600 is not surrounded by the guide sleeve 500. At this time, the radiation release of the radioactive source 900 is more complete.

[0053] In a preferred embodiment, as Figures 1 to 3 、 Figure 5 shown, the guide hole 510 is provided with a second opening at the end of the guide sleeve 500 far from the drive control assembly.

[0054] It can be understood that when the guide sleeve 500 is flush with the end of the shielding member 600 far from the drive control assembly, and the drive control assembly drives the radioactive source 900 to move through the traction member 400, the radioactive source 900 can be moved outside the guide sleeve 500 through the second opening, so as to realize the complete release of the radiation of the radioactive source 900.

[0055] It can be understood that when the end of the guide sleeve 500 far from the drive control assembly is set to extend outside the shielding member 600, the guide hole 510 can be provided with a second opening or not at the end of the guide sleeve 500 far from the guide shielding assembly. As long as the radioactive source 900 moves to the extended part of the guide sleeve 500 relative to the shielding member 600, this part can be used as the irradiation area, as long as the transfer of the radioactive source 900 inside and outside the shielding member 600 can be ensured, which will not be elaborated here.

[0056] In a preferred embodiment, as Figures 1 to 3 shown, the shielding member 600 is specifically set to be cylindrical, and the part of the guide sleeve 500 passing through the shielding member 600 is coaxial with the shielding member 600.

[0057] In the embodiments of the present application, by adopting the above-mentioned radioactive source control device, since the shielding member 600 is cylindrical and the part of the guiding sleeve 500 passing through the shielding member 600 is coaxial with the shielding member 600, when the radioactive source 900 moves to the corresponding position of the shielding member 600 within the guiding hole 510, the shielding member 600 can provide a uniform shielding effect for the radioactive source 900 in the radial direction of the guiding sleeve 500, thereby further improving the shielding stability.

[0058] In a preferred embodiment, the material of the shielding member 600 is set as high atomic number materials such as tungsten alloy, lead, molybdenum, or composite materials, polymers, etc.

[0059] It can be understood that the material and structural setting form of the shielding member 600 are not limited to the above solutions, and its specific setting form is formulated based on the type of the radioactive source 900 and the shielding requirements, as long as the shielding requirements can be met, which will not be elaborated here.

[0060] In a preferred embodiment, as Figures 1 to 3 shown, the drive control assembly includes a lead screw 240 arranged on the mounting base 100, a slide table 270 threadedly connected to the lead screw 240, and a power unit for driving the lead screw 240 to rotate. The slide table 270 is slidably connected to the mounting base 100 in the axial direction of the lead screw 240, and is fixedly provided with an engaging portion 260 fixedly connected to the traction member 400.

[0061] Among them, when the slide table 270 moves along the axial direction of the lead screw 240, it can synchronously drive the traction member 400 to move relative to the guiding sleeve 500.

[0062] In a preferred embodiment, as Figures 1 to 3 shown, the power unit includes a control motor 210 fixedly arranged on the mounting base 100. A driving transmission wheel 220 parallel to the central axis of the lead screw 240 is fixedly provided on the power output end of the control motor 210. A driven transmission wheel 230 is fixedly provided on the lead screw 240. A transmission belt 250 is wound between the driving transmission wheel 220 and the driven transmission wheel 230.

[0063] Among them, when the control motor 210 drives the driving transmission wheel 220 to rotate clockwise or counterclockwise, the driving transmission wheel 220 can drive the driven transmission wheel 230 and the lead screw 240 to rotate synchronously through the transmission belt 250, so as to realize the movement of the slide table 270 in the axial direction of the lead screw 240.

[0064] Specifically, when the control motor 210 rotates forward, the lead screw 240 rotates and drives the slide table 270 to move towards the shielding member 600, thereby realizing the switching of the radiation source 900 from the shielding state to the sample feeding state; when the control motor 210 rotates reversely, the lead screw 240 rotates and drives the slide table 270 to move away from the shielding member 600, thereby realizing the switching of the radiation source 900 from the sample feeding state to the shielding state.

[0065] It can be understood that the setting form of the drive control assembly is not limited to the above one. For example, it can be set as a transmission structure such as an electric cylinder, a cylinder, a rack and pinion, a worm and worm gear, etc., as long as it can apply a force to the traction member 400 and realize the position adjustment of the traction member 400 relative to the guide sleeve 500, which will not be elaborated here.

[0066] In a preferred embodiment, as Figures 1 to 3 shown, the drive control assembly further includes an induction assembly for sensing the relative position states of the traction member 400 and the shielding member 600.

[0067] In a preferred embodiment, as Figures 1 to 3 shown, the induction assembly includes a first induction switch 310 and a second induction switch 320 fixedly arranged on the mounting base 100, and further includes a triggering member 330 fixedly arranged on the slide table 270.

[0068] Among them, the first induction switch 310 and the second induction switch 320 are arranged at intervals along the axial direction of the lead screw 240, and the first induction switch 310 is located on the side of the second induction switch 320 away from the shielding member 600.

[0069] The triggering member 330 is located between the first induction switch 310 and the second induction switch 320, and can be coupled with the first induction switch 310 and the second induction switch 320 respectively to adjust the working state of the power unit.

[0070] It can be understood that when the triggering member 330 is coupled with the first induction switch 310, the radiation source 900 is located inside the shielding member 600, and at this time the control device is in the shielding state; when the drive control assembly drives the radiation source 900 to move outside the shielding member 600 and the triggering member 330 is coupled with the second induction switch 320, the power unit is turned off so that the radiation source 900 maintains its relative position with the shielding member 600, and at this time the control device is in the sample feeding state.

[0071] It can be understood that the setting form of the sensing component is not limited to the above one. For example, multiple groups of induction switches can be set on the travel path of the trigger 330, and each group of induction switches corresponds to one of the relative position points of the radiation source 900 and the shielding member 600. By cooperating the trigger 330 with the induction switches at different positions, irradiation of the radiation source 900 at different positions can be achieved. At this time, at least one induction switch is set such that the radiation source 900 is located inside the shielding member 600 when coupled with the trigger 330, and at least one induction switch is set such that the radiation source 900 is located outside the shielding member 600 when coupled with the trigger 330.

[0072] In a preferred embodiment, the first induction switch 310 and the second induction switch 320 are specifically set as photoelectric switches, proximity switches, microswitches, etc., as long as they can cooperate with the trigger 330, which will not be elaborated here.

[0073] In a preferred embodiment, as Figures 1 to 5 shown, the guide hole 510 has a bending section, and the traction member 400 is specifically set as a flexible member and is elastically slidably arranged in the guide hole 510 at the end far from the drive control assembly.

[0074] Among them, in the shielding state, the radiation source 900 is located inside the shielding member 600, and the end of the traction member 400 far from the drive control assembly has a tendency to move the radiation source 900 to the outside of the shielding member 600 under the action of its own elastic force; in the sample feeding state, the radiation source 900 is located outside the shielding member 600, and the end of the traction member 400 far from the drive control assembly is not affected by the elastic force, or has a tendency to slide away from the drive control assembly under the action of its own elastic force.

[0075] In the embodiment of the present application, by adopting the above-mentioned radiation source control device and setting the traction member 400 as a flexible member, the flexibility of the movement path of the radiation source 900 is greatly improved, and it can be flexibly applied to various instrument devices with complex or compact spaces, meeting the sample feeding control functions of the radiation source 900 at different distances, directions, and angles in different instrument devices. At the same time, when the drive control assembly pushes the traction member 400 to move away from the drive control assembly, the elastic force received by the end of the traction member 400 far from the drive control assembly and the thrust of the drive control assembly form a tension force, thereby avoiding bending deformation of the traction member 400 during the movement process and ensuring the switching efficiency and stability of the shielding state and the sample feeding state of the radiation source 900.

[0076] It can be understood that when the central axis of the guide hole 510 is set as a straight line, the traction member 400 can also be set as a rigid member, and at the same time, the elastic sliding fit structure between the traction member 400 and the guide hole 510 can be omitted. At this time, when the drive control assembly pushes the traction member 400 to move away from the drive control assembly, the traction member 400 can ensure its own structural stability and does not affect the switching of the working state of the radiation source 900, which will not be elaborated here.

[0077] In a preferred embodiment, the traction member 400 is specifically set as a steel wire rope.

[0078] It can be understood that the setting form of the traction member 400 as a flexible member is not limited to the above one. For example, the traction member 400 can also be set as a rubber rod or a hemp rope, as long as it can realize the adaptation of the traction member 400 to the bending path of the guide hole 510, which will not be elaborated here.

[0079] In a preferred embodiment, as Figures 1 to 5 shown, a first limiting member 810 is fixedly provided at the corresponding position of the end of the traction member 400 away from the drive control assembly, and a second limiting member 820 is fixedly provided at the corresponding position of the first opening of the guide hole 510 of the guide sleeve 500.

[0080] Wherein, a spring 700 located in the guide hole 510 is sleeved on the traction member 400, and both ends of the spring 700 are abutted against the corresponding ends of the first limiting member 810 and the second limiting member 820 respectively.

[0081] When the radiation source 900 is in the shielding state, the spring 700 is in a compressed state and has an elastic potential energy to drive the traction member 400 to move away from the drive control assembly; when the radiation source 900 is switched to the sample feeding state, the spring 700 releases the elastic potential energy, thereby driving the end of the traction member 400 away from the drive control assembly to move outside the shielding member 600.

[0082] It can be understood that the elastic sliding setting form of the end of the traction member 400 away from the drive control assembly in the guide hole 510 is not limited to the above one, as long as it can realize the elastic tension of the traction member 400 far away, which will not be elaborated here.

[0083] In a preferred embodiment, as Figures 1 to 4 shown, the second limiting member 820 is fixedly provided on the mounting base 100.

[0084] In a preferred embodiment, the traction member 400 and the first limiting member 810 are set as an integrally formed structure.

[0085] In a preferred embodiment, the guide sleeve 500 and the second limiting member 820, and / or the shielding member 600 are set as an integrally formed structure.

[0086] In a preferred embodiment, the guide sleeve 500 is specifically configured to be made of wear-resistant metal or polymer material.

[0087] It should be noted that in this text, the terms "including", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including that element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the reverse order according to the functions involved. For example, the described methods may be performed in an order different from that described, and various steps may also be added, omitted, or combined. Additionally, the features described with reference to certain examples may be combined in other examples.

However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive.
