Description

Technical Field

[0001] The invention relates to the field of radioactive material transport containers, in particular to an irradiation monitoring tube multi-in and multi-out transport container and an operation method thereof. Background Art

[0002] The irradiation monitoring tube is a device that is made by making the base material and weld material of the reactor pressure vessel into a sample, which is placed in a stainless steel tube and fixed on the outside of the cylinder of the core internal component hanging basket along the height of the core active section. Its main purpose is to be pulled out according to plan during the life of the reactor for performance testing and analysis, so as to monitor and predict the changes in the material of the pressure vessel after irradiation. The irradiation monitoring tube has strong radioactivity due to long-term exposure to neutron irradiation in the reactor. Therefore, the transportation of the irradiation monitoring tube requires a specific transport container to shield its radioactivity and ensure safety during transportation.

[0003] The current transport container adopts a top-in-top-out solution for loading and unloading irradiation supervision tubes, that is, when the irradiation supervision tube needs to be loaded, the upper end cover of the container is opened first, and the irradiation supervision tube is placed into the container from the upper port of the transport container through a gripper. When the irradiation supervision tube needs to be taken out, the upper end cover of the container is also opened first, and the gripper takes out the irradiation supervision tube through the upper port of the transport container. However, due to the increase in application scenarios, the irradiation supervision tube needs to enter from the upper port of the transport container and be taken out from the lower port, enter from the lower port of the transport container and be taken out from the upper port, enter from the lower port of the transport container and be taken out from the lower port, and enter from the lower port of the transport container and be taken out from the lower port, which requires the transport container to have multiple transfer functions such as top-in-top-out, top-in-bottom-out, bottom-in-top-out, and bottom-in-bottom-out. Therefore, the current method can no longer meet the use requirements, and it is necessary to develop a irradiation supervision tube transport container with multiple entry and exit functions.

In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0046] The technical solution adopted by the present invention to solve the technical problem is: Figures 1 to 7 The present invention discloses a multi-input and multi-output transport container for irradiation monitoring tubes, comprising:

[0047] A transport container body 1, wherein a hollow isolation channel 2 with two ends opened is arranged inside the transport container body 1, and a first shielding member 3 for isolating radiation leakage is filled and arranged between the wall of the isolation channel 2 and the inner wall of the transport container body 1;

[0048] A rope lifting mechanism, which is installed on the transport container body 1 and inserted into the top of the isolation channel 2;

[0049] A hanging basket 4, which is hollow inside and has an open top, and is suspended in the isolation passage 2 through a rope lifting mechanism;

[0050] An upper end cover 5, which is installed in the opening at the top of the isolation passage 2 and is used to close or open the isolation passage 2 so that the transport container body 1 forms a sealed space;

[0051] The shielding door 6 is installed in the opening at the bottom of the isolation passage 2 and is used to close or open the opening at the bottom of the isolation passage 2 so that the transport container body 1 forms a sealed space.

[0052] Preferably, the irradiation monitoring tube is placed in the hanging basket 4, and the hanging basket 4 is suspended inside the isolation channel 2 by a rope at the top of the transport container body 1, and then the upper end cover 5 and the shielding door 6 are used to close the openings at the upper and lower ends of the isolation channel 2, so that the transport container body 1 forms a sealed space, which can prevent the leakage of radioactive substances on the irradiation monitoring tube.

[0053] Alternatively, the transport container body 1 is a cylindrical structure, the hanging basket 4 is also a cylindrical structure, and the bottom of the hanging basket 4 is a non-opening structure, and the irradiation monitoring tube is loaded into the hanging basket 4 from the top opening of the hanging basket 4.

[0054] Specifically, the upper end cover 5 is installed on the transport container body 1 by bolts, screws, etc., and optionally, the upper end cover 5 is rotatably installed on the transport container body 1 by hinges. The part of the upper end cover 5 inserted into the isolation channel 2 is made of flexible radiation protection material, which can be deformed and can be better inserted into the isolation channel 2 for sealing. The flexible material part of the upper end cover 5 has an interference fit with the isolation channel 2.

[0055] In addition, it is preferred that the upper end cover 5 is tightly installed with the isolation channel 2 to avoid a gap therebetween, and the upper end cover 5 is internally installed with radiation-proof materials, such as lead, cement and other materials, which are not limited here.

[0056] Depend on Figures 2 to 4 It is shown that the transport container body 1 comprises an inner shell 11 and a plug 7;

[0057] The inner cavity of the inner shell 11 forms an isolation channel 2 , and a plug 7 is installed at the bottom opening of the inner shell to close the isolation channel 2 .

[0058] Preferably, the plug 7 seals the bottom opening of the isolation channel 2 to prevent leakage of radioactive substances on the irradiation monitoring tube. The structure and material of the plug 7 are the same as those of the upper end cover 5 mentioned above, which will be explained again here.

[0059] It is important to note that when the staff needs to open the bottom of the transport container, they first need to remove the plug 7, then rotate the transport container body 1 to a certain angle to prevent the isolation channel 2 from directly corresponding to the staff, and then rotate the shielding door 6 to open the isolation channel 2. This can prevent the radioactive substances on the irradiation monitoring tube from directly irradiating the human body when the isolation channel 2 is opened, which provides good protection for the staff.

[0060] The rope lifting mechanism includes a rope drum assembly 8, a hollow rope duct 81, and a rope; the rope drum assembly 8 is installed on the transport container body 1, the rope duct 81 is buried in the first shielding component 3, one end of which is opened and extends to the top surface of the transport container body 1, and the other end is opened and connected to the side wall of the inner shell 11. The rope is installed in the rope duct 81, one end of which is wound on the rope drum assembly 8, and the other end is connected and installed on the top of the hanging basket 4.

[0061] Preferably, the rope drum assembly 8 includes a bracket installed on the top of the transport container body 1 and a drum rotatably installed on the bracket, and the rope is wound up by rotating the drum to lift the hanging basket 4.

[0062] Alternatively, a motor is installed on one side of the bracket, the output end of the motor is connected to the drum, and the motor drives the drum to rotate to reel in the rope.

[0063] Specifically, the device winds up the rope by manually rotating the rope reel assembly 8, thereby lifting the hanging basket 4.

[0064] One end of the rope guide 81 is mounted on the top wall of the transport container body 1, and the other end is mounted on the side wall of the inner shell 11, and the rope guide 81 is connected to the isolation channel 2, and the rope is inserted into the rope guide 81. There are two rope drum assemblies 8, rope guides 81, and ropes, which are respectively mounted on both sides of the inner shell 11, so that the ropes are fixed to both sides of the top of the hanging basket 4 to prevent the hanging basket 4 from tilting during the hoisting process.

[0065] The rope is fixed at the bilaterally symmetrical position of the top of the hanging basket 4. It can also be selected that the rope is a steel wire rope, a straw rope, etc., which is not limited here, and what this device uses is a steel wire rope.

[0066] The rope conduit 81 is curved, connected from the top surface of the transport container body 1 to the side wall of the inner shell 11, to prevent radiation leakage; or, the rope conduit 81 is straight, connected from the top surface of the transport container body 1 to the side wall of the inner shell 11 at an angle, to prevent radiation leakage.

[0067] Preferably, the rope guide 81 is set to an arc or a certain tilt angle to prevent radioactive substances from leaking straight up and down from the rope guide 81. Setting a certain arc and angle can prevent radiation leakage. And setting a certain arc and angle facilitates the movement of the rope inside it and avoids the right-angle edge from wearing the rope.

[0068] Depend on Figures 1 to 4 It is given that the rope lifting mechanism also includes a sealing cover 82 detachably mounted on the transport container body 1, and the rope drum assembly 8 is buckled inside the sealing cover 82, and the inner wall of the sealing cover 82 is provided with a radiation leakage prevention layer for preventing radiation leakage at the rope drum assembly 8.

[0069] Preferably, the sealing cover 82 is a cylindrical shell structure with a thread on the outside of the shell opening end. The top of the transport container body 1 is connected to the rope drum assembly 8 bracket with a cylindrical threaded hole, which can cooperate with the sealing cover 82 thread to achieve wire rope sealing and prevent radioactive material from leaking from here.

[0070] Specifically, during lifting, the sealing cover 82 is removed, and after the lifting of the hanging basket 4 is completed, the sealing cover 82 is reinstalled on the transport container body 1 to seal the rope.

[0071] When the hanging basket 4 needs to be raised, the wire rope is pulled by the rope drum assembly 8, and the wire rope drives the hanging basket 4 to rise. When the hanging basket 4 needs to be dropped, the rope drum assembly 8 is rotated to allow the hanging basket 4 to drop under its own weight.

[0072] Depend on Figures 2 to 6 It is shown that the shielding door 6 includes a rotor shielding body 61, a rotating shaft 62, and a rotor channel 63 passing through the rotor shielding body 61; the rotor shielding body 61 is rotatably installed on the inner wall of the inner shell 11 through the rotating shaft 62, and the rotor shielding body 61 is located at the opening at the bottom of the isolation channel 2.

[0073] Preferably, the rotor shield 61 rotates around the rotating shaft 62, and the rotor shield 61 is a cylindrical structure, and a rotor channel 63 having the same diameter as the isolation channel 2 is left on the side of the cylinder. By rotating the rotor shield 61, the rotor channel 63 is directly opposite to the isolation channel 2 (i.e., the container is in an open state) or the rotor channel 63 is perpendicular to the isolation channel 2 (i.e., the container is in a closed state). The shield door 6 at the bottom of the transport container body is used to realize the opening and closing functions of the transport container.

[0074] It is also preferred that a support frame is installed on the outside of the shielding door 6, the support frame is installed on the bottom of the transport container body 1 by bolts, and the support frame is located in the bottom opening of the isolation channel 2, or the width of the support frame is larger than the isolation channel 2, but the center of the support frame is in a straight line with the center of the isolation channel 2.

[0075] In addition, preferably, the inner diameter of the rotor channel 63 is equal to or greater than the inner diameter of the isolation channel 2, and the outer diameter of the hanging basket 4 is smaller than the inner diameter of the isolation channel 2, so that it is convenient to take the hanging basket 4 out of and put it into the isolation channel 2.

[0076] A second shielding member 64 is disposed in the rotor shielding body 61 to prevent radiation leakage from the bottom opening of the isolation channel 2 .

[0077] Preferably, the second shielding member 64 is made of lead, cement or other materials that can prevent leakage of radioactive substances, and seals the bottom opening of the isolation channel 2 to prevent the spread of radioactive substances.

[0078] In addition, preferably, a limiting mechanism cooperating with the rotor shielding door 6 is also installed on the transport container body 1, and the limiting mechanism includes a fixing part and a positioning hole; the positioning hole is opened on the transport container body 1, the fixing part is installed on the rotating shaft 62, and the fixing part is installed in the positioning hole when the rotating shaft 62 is not rotating.

Through the matching of the fixing member and the positioning hole on the rotating shaft 62, the rotating shaft 62 is limited by the fixing member within a rotatable range of 90°, and the fixing of the rotating shaft 62 in the rotatable direction is realized, that is, the limiting and positioning of the rotor channel 63 is realized, and the rotor channel 63 is connected or disconnected with the isolation channel 2.

[0080] The transport container body 1 also includes an outer shell 12, an upper head 13 and a lower head 14; the upper head 13 is installed on the top of the outer shell 12 and the inner shell 11, the lower head 14 is installed on the bottom of the outer shell 12 and the inner shell 11, the first shielding member 3 is installed between the outer shell 12 and the inner shell 11, the top opening of the isolation channel 2 is opened on the upper head 13, and the bottom opening of the isolation channel 2 is opened on the lower head 14.

[0081] Preferably, the inner shell 11, the outer shell 12, the upper head 13 and the lower head 14 are connected by welding to form the transport container body 1, and an integrally formed structure can also be adopted. The first shielding member 3 between the inner shell 11 and the outer shell 12 of the present application is made of lead material. After the inner shell 11, the outer shell 12 and the upper head 13 are welded together, lead water is poured between the inner shell 11 and the outer shell 12. After naturally cooling to form a solid, the lower head 14 is welded to the outer shell 12 and the bottom of the inner shell 11.

[0086] S3, open the shielding door 6, and lower the rope-mounted hanging basket 4 to the bottom of the transport container. Then, load the irradiation monitoring tube into the hanging basket 4 and lift it into the transport container. Open the upper end cover 5 and take the irradiation monitoring tube out from the top of the transport container.
