[0002] Thermoluminescence detector is a device that uses the principle of thermoluminescence to measure nuclear radiation. Thermoluminescence luminophore serves as a dose element, which stores and accumulates the energy of the received rays. After being heated by the thermoluminescence heating device, the dose element emits light, which is converted into an electrical signal through a photomultiplier tube and output for display.

[0003] Thermoluminescent irradiator is a quality control device for thermoluminescent detectors, which can be used to calibrate the accuracy of thermoluminescent detectors. The irradiator contains a radioactive source and contains harmful rays to the human body. In the prior art, the entire device needs to be opened during the loading and unloading process of the thermoluminescent irradiator, and the sample to be irradiated needs to be installed under the irradiation source. Then the opening of the device is closed and the irradiation operation is carried out. Similarly, the unloading process also needs to perform similar operations. In this process, due to the heavy sample loading, the staff are exposed to harmful rays for a long time, which requires going to a special site with shielding function to operate, which increases the cumbersomeness and complexity of the irradiation operation and reduces the efficiency of the operation. Secondly, this operation method increases their exposure time to harmful rays and poses a greater safety risk.

[0004] Therefore, it is necessary to design a new type of thermoluminescence irradiation open-door sample loading structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A novel thermoluminescent irradiation door-opening sample loading structure comprises an irradiation box 1, a thermoluminescent irradiation device 2 is installed on the inner top surface of the irradiation box 1, a tray-taking port 4 is provided on the irradiation box 1, and the tray-taking port 4 and the thermoluminescent irradiation device 2 are respectively located on both sides of the inside of the irradiation box 1. When sampling, since the tray-taking port 4 is far away from the thermoluminescent irradiation device 2, the harmful rays exposed to the staff can be reduced, and the safety risk can be reduced. A flap 5 corresponding to the tray-taking port 4 is provided on the irradiation box 1, and a rubber ring 10 is provided at the bottom of the flap 5. The rubber ring 10 can increase the sealing of the irradiation box 1, thereby increasing the shielding effect of the device and reducing the harm to the staff. The irradiation box 1 is provided with a flap 5 for placing An irradiation disk 6 of the element to be irradiated is placed, and the disk opening 4 is adapted to the size of the irradiation disk 6, so that while ensuring that the irradiation disk 6 can be taken out, the radiation in the disk opening 4 will not be exposed too much. The interior of the irradiation box 1 is provided with a transverse moving member 3 for moving the irradiation disk 6 to the disk opening 4. Specifically, the transverse moving member 3 is composed of a transverse moving motor, a transmission device, a guide rail and a sliding seat. The transverse moving motor is fixed on the bottom surface of the irradiation box 1, the transmission device is arranged between the transverse moving motor and the guide rail, and the sliding seat is arranged on the guide rail, so that the transverse moving motor can drive the sliding seat to move. Its specific structure and working principle are all existing technologies, and no further details are given here. The interior of the irradiation box 1 is also provided with a connecting component.

[0023] Reference Figure 2The connecting component includes a base 71 arranged on the transverse member 3, and a positioning sensor 72 is provided on the base 71. The positioning sensor 72 enables the irradiation disk 6 to rotate evenly to the bottom of the thermoluminescent irradiation device 2 for irradiation operation. A rotating shaft 74 is provided in the base 71, and two bearings 75 are sleeved on the rotating shaft 74. The inner ring of the bearing 75 is fixed to the rotating shaft 74, and the outer ring of the bearing 75 is fixed to the inside of the base 71. A rotating motor 73 is also fixed on the base 71, and a transmission member 76 is provided between the rotating shaft 74 and the output shaft of the rotating motor 73. It is worth mentioning that the transmission member 76 adopts a chain drive transmission method. Specifically, the transmission member 76 may include two synchronous wheels and a synchronous belt. The synchronous belt is sleeved on the two synchronous wheels. The two synchronous wheels are respectively fixedly sleeved on the output shaft of the rotating motor 73 and the rotating shaft 74, so as to realize the transmission between the rotating motor 73 and the rotating shaft 74. It should be understood that the transmission member 76 adopts a synchronous wheel and a synchronous belt. Transmission is not the only implementation method. In some other embodiments, the transmission member 76 can also be transmitted by a sprocket and a chain. The transmission method of the sprocket and the chain is similar to the transmission method of the synchronous wheel and the synchronous belt, which will not be described here. In addition, the wrap angle of the transmission member 76 is greater than one hundred and twenty degrees to ensure the normal and stable operation of the device. Two positioning ports 78 are provided on the irradiation disk 6, and two positioning columns 77 are fixed on the top of the rotating shaft 74, and the positioning columns 77 are adapted to the positioning ports 78. Under the action of the positioning ports 78 and the positioning columns 77, the irradiation disk 6 can be quickly installed on the rotating shaft 74, which improves the operating efficiency of the staff, reduces the loading time, and thereby reduces the harm of radiation to the staff. An adsorption magnet 9 is embedded in the center position of the bottom of the irradiation disk 6, and the top of the rotating shaft 74 is magnetic. When the irradiation disk 6 is installed on the rotating shaft 74, under the action of the adsorption magnet 9, the irradiation disk 6 can be fixed to ensure the stability of the irradiation disk 6 during movement.

[0024] Reference Figure 3 and Figure 4 The irradiation box 1 is also provided with a rotating assembly, which includes two corner pieces 83 fixedly connected to the irradiation box 1, and a connecting shaft 81 is rotatably connected between the two corner pieces 83. The flap 5 is fixedly sleeved on the connecting shaft 81, and a damping gasket 82 is also provided between the connecting shaft 81 and the corner piece 83. By providing the damping gasket 82, the staff does not need to perform additional fixing operations after opening or closing the flap 5, which simplifies the operation process and improves the working efficiency.

[0025] The specific working principle of the utility model is as follows:

[0026] When loading, the staff turns the flap 5 to open the plate taking port 4, then aligns the positioning port 78 on the irradiation disk 6 with the positioning column 77, and places the irradiation disk 6 on the rotating shaft 74. In this way, under the action of the positioning port 78 and the positioning column 77, the irradiation disk 6 can be placed quickly and accurately. Furthermore, since the top of the rotating shaft 74 is magnetic and the irradiation disk 6 is provided with an adsorption magnet 9, when the irradiation disk 6 is placed on the rotating shaft 74, the position of the irradiation disk 6 can be fixed. Then the staff closes the flap 5. Under the action of the damping gasket 82, the staff no longer needs to fix the flap 5. The transverse moving member 3 is started. The transverse moving member 3 drives the base 71 and the irradiation disk 6 to move to the bottom of the thermoluminescent irradiation device 2, and then the rotating motor 73 is started. Under the transmission action of the transmission member 76, the rotating motor 7 The rotation of the output shaft of 3 can drive the rotating shaft 74 to rotate, so that the irradiation disk 6 can rotate, so that the surface of the irradiation disk 6 can be moved in sequence and orderly to the position directly below the thermoluminescent irradiation device 2 to ensure the uniformity of irradiation. Similarly, when discharging, the irradiation disk 6 moves to a position directly opposite to the disk-taking opening 4 under the action of the transverse moving member 3, and the staff opens the flip cover 5 to manually extract the irradiation disk 6. The irradiation disk 6 and the equipment can be separated without any tools in the middle. This design reduces the tediousness of loading and unloading for the staff, reduces the contact time with the inside of the equipment, and thus reduces the harm of radiation to the staff. Secondly, because the operation is quick and convenient, and the material-taking position is far away from the radiation source, this also reduces the exposure to radiation, so that the staff does not need to operate in a special place, thereby improving the efficiency of the irradiation operation.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
