Description

Technical Field

[0001] The invention belongs to the field of radioactive source application and relates to an automated gamma ray source container. Background Art

[0002] With the continuous popularization of nuclear physics technology, the application of radioactive sources has increasingly penetrated into multiple scenarios in life. However, the management and application of source containers today require a lot of manpower and material resources to open and close the source containers. The operation process is cumbersome, inefficient, and extremely unsafe and uncontrollable. The radiation outlets of most radiation source containers used today are relatively single, usually set to a single channel, but such a single channel will greatly limit the application scenarios of the source container, and in most application scenarios, the single-channel source container has certain limitations, resulting in low work efficiency and affecting the use effect of the source container.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The purpose of the present invention is to provide an automated gamma-ray source container, which realizes automated control of the entire source container by setting a driving device, thereby enabling rapid opening and closing of the source container, and can further improve the working efficiency of the source container when combined with a three-channel ray tube.

[0005] In order to achieve the above-mentioned purpose of the present invention, the following technical solutions are particularly adopted: An automated gamma-ray source container comprises a source container body, wherein the source container body mainly comprises a driving device and a three-channel ray tube, wherein the driving device is fixedly arranged on the top of the three-channel ray tube; the driving device comprises a shell and a driving component arranged inside the shell, wherein the driving component comprises a motor, an electromagnetic coupler, a lead screw and a lead screw nut; and a ray source and three ray channels radiating outwards from the ray source are arranged inside the three-channel ray tube.

[0006] In the automated gamma-ray source container of the present invention, the driving device is mainly combined with a three-channel ray tube to realize the function of automatically controlling the opening and closing of the source container. Moreover, since the driving device and the three-channel ray tube are combined, the prepared source container can have more advantages than the single-channel source container. Only when the driving device is combined with the three-channel ray tube can the prepared source container have higher working efficiency. Moreover, by automatically controlling the movement of the ray source in the three-channel ray tube through the driving device, the overall flexibility of the source container can be greatly improved. Compared with the traditional manual operation to realize the opening and closing of the source container, this method has higher safety and working efficiency. Moreover, due to the setting of the three-channel ray tube, the application scenarios of the source container can be greatly expanded. In combination with the automated driving device, the opening and closing of the source container can be automatically controlled while scattering the ray source outward in multiple channels, so that the coverage range of the ray of the source container is wider and more comprehensive, which has great advantages in actual application scenarios. However, due to the difference in application scenarios between the single-channel source container and the three-channel source container, the single-channel source container and the drive device are not applicable to each other. This is because the use of a drive device in the application scenario of a single-channel ray tube will make the source container itself have great safety hazards, and the application scenario of the three-channel source container has higher requirements for the response speed of the ray source. Controlling the response of the ray source through an automated drive device can make the source container have an extremely high response speed, thereby improving the working efficiency of the source container.

[0007] Preferably, as a further implementable solution, the lead screw is arranged at the center of the interior of the housing, and the motor is arranged at one end of the lead screw.

[0008] In the present invention, a motor is provided and connected to a lead screw so that the source container can be automatically managed. The motor is controlled by a power supply connected to the outside of the motor so that the motor provides power to the lead screw, which rotates inside the source container, thereby achieving the purpose of automatically controlling the source container.

[0009] Preferably, as a further implementable solution, an actuator rod is provided at the top center of the three-channel ray tube, a groove is provided at the top of the actuator rod, and the lead screw is fixedly connected to the actuator rod through the groove.

[0010] Preferably, as a further implementable solution, a radiation source is fixedly connected to the end of the actuator rod.

[0011] Preferably, as a further implementable solution, a channel is provided at the center of the three-channel ray tube, and the actuator rod can move in the channel.

[0012] In the present invention, a groove is provided at the top of the actuator rod so that one end of the lead screw is engaged with the groove, and then the motor, the lead screw and the actuator rod are formed into a whole, and the automatic control of the source container can be realized by an external power supply connected to the motor, and the motor provides power to the lead screw so that the lead screw rotates inside the source container, thereby driving the lead screw nut to move on the lead screw. At this time, the actuator rod located below the lead screw nut can move in the three-channel ray tube under the push of the lead screw nut, and the ray source connected to the end of the actuator rod can move in the three-channel ray tube under the drive of the actuator rod. When the ray source moves to the center of the three-channel ray outlet, that is, the working position, the multiple channel openings of the source container will emit rays, and the source container is in an open state; and when the actuator rod continues to move forward to the shielding position, since the three-channel ray tube is a solid lead block with poor penetration, when the ray source moves to the shielding position, the multiple channels of the source container will not emit rays, and the source container is in a closed state.

[0013] Preferably, as a further implementable solution, the electromagnetic coupler includes a first coupler arranged on the motor and a second coupler arranged on the lead screw, for fixedly connecting the motor to the lead screw.

[0014] In the present invention, the motor and the lead screw are integrated through an electromagnetic coupler, wherein the electromagnetic coupler and the motor are both externally connected to a power supply. Since the motor and the lead screw are two independent entities, the present invention controls the motor and the lead screw to be connected to each other to form a whole by setting an electromagnetic coupler through an external power supply. When the source container is required to emit rays, the external power supply connected to the electromagnetic coupler and the motor is turned on, and the electromagnetic coupler is coupled at this time. Since the first coupler is arranged on the motor and the second coupler is arranged on the lead screw, the coupling of the electromagnetic coupler makes the motor and the lead screw integrated, thereby controlling the rotation of the lead screw through the motor, and then controlling the opening and closing of the source container.

[0015] Preferably, as a further implementable solution, a screw support seat is further provided between the screw nut and the electromagnetic coupler, and the screw support seat is used to support the screw rod so that it is not easy to deviate in the source container.

[0016] Preferably, as a further implementable solution, an operating rod is provided on one side of the driving device, the operating rod passes through the housing and extends into the housing, an upper bevel gear set is provided at one end of the operating rod; a lower bevel gear set is also provided between the screw nut and the screw support seat.

[0017] In the present invention, an operating rod is arranged on the outside of the driving device, a part of the operating rod is extended into the three-channel ray tube, an upper bevel gear set is arranged on the part of the operating rod extending into the three-channel ray tube, and a lower bevel gear set is arranged on the lead screw, so that when the driving device cannot work normally, the opening and closing of the source container can be manually controlled by the operating rod, and the driving device and the operating rod are arranged, so as to realize flexible control of the source container.

[0018] Preferably, as a further implementable solution, a linear bearing is provided above the upper bevel gear set, and the linear bearing is used to fix the upper bevel gear set to prevent it from sliding on the operating rod.

[0019] The working process of the automated gamma-ray source container of the present invention is specifically as follows: Turn on the motor connected to the motor and the electromagnetic coupler. At this time, the electromagnetic coupler is coupled so that the motor and the lead screw are connected to form an integral body, so that the motor can provide power for the lead screw, so that the lead screw rotates in the source container, thereby driving the lead screw nut on the lead screw to press the lead screw downward, and pushing the actuator rod below the lead screw nut to move in the three-channel ray tube. At this time, since the ray source is connected to the actuator rod, the ray source can slide in the channel set in the three-channel ray tube under the drive of the actuator rod. When the ray source moves to the center of the three ray channels, the source container is in an open state, and rays are emitted from multiple ray channels; When the actuator rod continues to move, the radiation source continues to move so that the radiation source misses the radiation channel. At this time, no radiation is emitted from the source container, and the source container is in a closed state. When the driving device is damaged and cannot control the closing of the source container, the operating lever set on the outside of the driving device can be manually operated to press the operating lever down, so that the upper bevel gear set and the lower bevel gear set are engaged. Then, the operating lever can be manually rotated to drive the lead screw to rotate, thereby driving the radiation source to move in the three-channel radiation tube, so that the source container can be manually opened and closed in this way.

[0020] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides an automated gamma-ray source container, which realizes automated control of the entire source container by setting a driving device, thereby enabling rapid opening and closing of the source container. Combining the source container with a three-channel ray tube can further improve the working efficiency of the source container. BRIEF DESCRIPTION OF THE DRAWINGS
