Abstract
Description
Technical Field
[0001] This utility model belongs to the field of radioactive source applications and relates to a gamma-ray source container. Background Technology
[0002] The application of radioactive sources is now widespread. Most of them are applied by sealing the radioactive source in a metal shell or tight covering layer and placing it in a specially designed container to prevent the radioactive source from causing harm to the human body. However, the current use of radiation source containers is relatively simple. Most radiation source containers only have one function: opening or closing. Switching between opening and closing often requires manual operation. During operation, it is necessary to wear protective equipment, minimize operation time, and maintain an operating distance to avoid accidental exposure and danger. Therefore, the use and management of radiation source containers are now quite complex and cumbersome, and the operation process is extremely dangerous.
[0003] In view of the above, this utility model is hereby proposed. Utility Model Content
[0004] The purpose of this invention is to provide a gamma-ray source container that combines a rotating mechanism assembly with a switching component. The switching component drives the rotating mechanism assembly, enabling the source container to simultaneously turn the source radiation on and off. Furthermore, it has a locking function in each state, giving the source container extremely high safety and good use and management of the radiation source.
[0005] In order to achieve the above-mentioned objectives of this utility model, the following technical solution is adopted:
[0006] A gamma-ray source container includes a source container shell, within which a rotating mechanism assembly is disposed. The rotating mechanism assembly includes an eccentric shield and a rotating rod, the rotating rod penetrating the surface of the source container shell. A gamma-ray outlet is disposed within the eccentric shield. Two limiting holes are also disposed on the surface of the source container. A gamma-ray source is disposed at the center of the source container shell, and the eccentric shield is disposed below the gamma-ray source. A switching assembly is disposed on one side of the top of the source container, and the switching assembly is connected to the rotating mechanism assembly.
[0007] In this invention, the switching of the working state of the source container is achieved by setting a rotating mechanism assembly combined with a switching component, so that the source container itself has the function of opening and closing the source ray at the same time.
[0008] Preferably, as a further feasible option, a positioning groove is provided at the center of the top of the eccentric shield, and the rotating shaft is fixedly connected to the eccentric shield through the positioning groove.
[0009] Preferably, as a further feasible option, the eccentric shield is a solid cylindrical lead block, and the radiation outlet is located at the edge of the eccentric shield.
[0010] Preferably, as a further feasible option, the switching assembly includes a moving rod, a handle, a locking device, and a lock, the moving rod being disposed between the two limiting holes.
[0011] Preferably, as a further feasible solution, the two ends of the movable rod are respectively provided with a fixing groove and a sleeve, the sleeve being connected to the rotating rod to connect the rotating rod to the rotating mechanism assembly.
[0012] Preferably, as a further feasible solution, the bottom of the handle is provided with a protrusion that abuts against the fixing groove, for fixing the handle to the rotating rod, so that the rotating mechanism assembly is rotated by rotating the rotating rod through the handle.
[0013] Preferably, as a further feasible option, a locking hole is provided between the fixing groove and the sleeve, and the locking device passes through the locking hole and abuts against the limiting hole to fix the rotating rod.
[0014] Preferably, as a further feasible option, the lock is disposed between the sleeve and the locking device.
[0015] Preferably, as a further feasible option, the bottom of the source container housing is provided with a flange base for fixing the source container housing to the flange base.
[0016] Preferably, as a further feasible option, a lifting ring is also provided on the outside of the source container shell.
[0017] The specific operation process of the gamma-ray source container of this invention is as follows:
[0018] Before the source container is used, the moving rod is located between the two limiting holes. Then, by rotating the handle, the moving rod is moved above the limiting hole that represents opening, so that the moving rod drives the rotating rod in the rotating mechanism assembly to rotate. At this time, the eccentric shield, which is fixedly connected to the rotating rod, will rotate around the moving rod as the center under the drive of the rotating rod, thereby rotating the radiation outlet set at the edge of the eccentric shield to below the radiation source. At this time, the source container is in the open state, and radiation is emitted from the radiation outlet. In order to ensure that the source container can be stably in the open state and to facilitate management, the working state of the source container can be locked by passing a locking device through the locking hole and the limiting hole.
[0019] Then, by rotating the handle to move the lever above the limit hole representing closure, the lever drives the rotating rod in the rotating mechanism assembly to rotate. At this time, the eccentric shield, which is fixedly connected to the rotating rod, will cause the radiation outlet to be offset from the radiation source under the action of the rotating rod. Since the eccentric shield itself is a solid lead block, the eccentric shield blocks the radiation source at this time. At this time, the source container is in a closed state, and no radiation is emitted from the radiation outlet.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] (1) The gamma-ray source container provided by this utility model has a rotating mechanism assembly, which enables the source container to simultaneously open and close the source radiation, and has a locking function in each state, so that the source container has extremely high safety and good use and management of the radiation source.

[0027] To more clearly illustrate the technical solution of this utility model, the following description is provided in the form of specific embodiments.
[0028] Example 1
[0029] Please see Figure 1-2 As shown, this utility model is a gamma-ray source container, including 1. a source container shell; 2. a radiation source; 3. a rotating rod; 4. an eccentric shield; 5. a radiation outlet; 6. a flange bottom; 7. a lifting ring; 8. a sleeve; 9. a lock; 10. a locking device; 11. a handle; 12. a moving rod; and 13. a limiting hole.
[0030] In this utility model, a source container shell 1 is included, wherein a rotating mechanism assembly is provided inside the source container shell 1. The rotating mechanism assembly includes an eccentric shield 4 and a rotating rod 12, and the rotating rod 12 passes through the surface of the source container shell 1, such that one end of the rotating rod 12 protrudes out of the source container shell 1.
[0031] In this invention, the surface of the source container shell 1 is provided with two limiting holes 13, see reference. Figure 2 The two limiting holes 3 represent the current state of the source container, such as... Figure 2 As shown, the source container is currently open.
[0032] In this utility model, the eccentric shield 4 is disposed below the radiation source 2. The eccentric shield is a solid cylindrical lead block, and a radiation outlet 5 is provided at the edge of the eccentric shield 4.
[0033] In this utility model, the switching assembly includes a moving rod 12, a handle 11, a locking device 10, and a lock; wherein the two ends of the moving rod 12 are respectively provided with a fixing groove and a sleeve 8, and the sleeve 8 is connected to the moving rod 12 through mutual docking, thereby connecting the moving rod 12 to the rotating mechanism assembly located inside the source container shell 1, so that rotating the 12 will drive the rotating mechanism assembly to move, thereby realizing the switching of the working state of the source container;
[0034] The bottom of the handle 11 is provided with a protrusion, which corresponds to the fixing groove provided on the moving rod 12, so that the handle 11 and the moving rod 12 form an operating lever;
[0035] In this utility model, a locking hole is also provided between the fixing groove and the sleeve 8. The locking hole passes through the moving rod 12, so that when the operating rod is rotated to align the locking hole with the limiting hole provided on the top surface of the source container shell, the locking device 10 is placed in the locking hole. At this time, the locking device 10 will pass through the locking hole and the limiting hole, thereby fixing the operating rod. At this time, the source container will be fixed in a working state.
[0036] Lock 9 is located between sleeve 8 and locking device 10. When the source container is fixed in a working state by locking device 10, the source container can be locked by lock 9, thereby achieving good use and management of the source container.
[0037] In this utility model, a flange bottom 6 is provided at the bottom of the source container housing 1 for fixing the source container housing 1 on the flange bottom 6; and a lifting ring 7 is provided on the outer side of the source container housing 1.
[0038] The specific operation process of the source container in this utility model is as follows:
[0039] Before the source container is used, the moving rod 12 is located between the two limiting holes. Then, by rotating the moving rod 12 with the handle 11 to the limit hole 13 representing opening, the moving rod drives the rotating rod 3 in the rotating mechanism assembly to rotate. At this time, the eccentric shield 4, which is fixedly connected to the rotating rod 3, will rotate around the moving rod as the center under the drive of the rotating rod 3, thereby rotating the radiation outlet 5 set at the edge of the eccentric shield 4 to the bottom of the radiation source 2. At this time, the source container is in the open state, and radiation is emitted from the radiation outlet 5. In order to make the source container stably in the open state and facilitate management, the locking device 10 can pass through the locking hole and the limiting hole to lock the working state of the source container.
[0040] Then, by rotating the handle 11 to move the moving rod 12 above the limit hole 13 representing closure, the moving rod 12 drives the rotating rod 3 in the rotating mechanism assembly to rotate. At this time, the eccentric shield 4, which is fixedly connected to the rotating rod 3, will cause the radiation outlet 5 to be offset from the radiation source 2 under the action of the rotating rod 3. Since the eccentric shield 4 itself is a solid lead block, the eccentric shield blocks the radiation source 2 at this time. At this time, the source container is in a closed state, and no radiation is emitted from the radiation outlet 5.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
