[0023] like Figure 1-4 As shown, the electric heater 104 is electrically connected to the controller 103, the servo motor 105 is electrically connected to the controller 103, the top output end of the servo motor 105 is fixedly connected to a threaded rod 106, and the top end of the threaded rod 106 is connected to the top inner wall of the observation box 101 through a bearing.

[0024] like Figure 1-4 As shown, a nut seat 107 is provided on the threaded rod 106 through a threaded sleeve, and the left end of the nut seat 107 is fixedly connected to the lifting frame 205. A limiting groove 109 is provided on the inner wall of the left end of the observation box 101, and the left end of the lifting frame 205 is fixedly connected to the limiting block 110, and the limiting block 110 is located in the limiting groove 109.

[0025] like Figure 1-4 As shown, four groups of sockets 208 are provided at the top of the bottom of the lifting frame 205 , and the bottom ends of the four groups of thermoluminescent dosimeter bodies 203 are fixedly connected with plug rods 209 , and the plug rods 209 are all located in the sockets 208 .

[0026] During implementation, the servo motor 105 is controlled by the controller 103 to drive the monitoring component 2 to rise as a whole. Through the operation of multiple groups of thermoluminescent dosimeter bodies 203, radiation of different energies can be identified and monitored at the same time. The setting of the electric heater 104 can heat the thermoluminescent dosimeter body 203, which is convenient for personnel to observe and record the monitoring results. The overall structure is simple, stable, easy to use, and has good practicality.

[0027] Example 2:

[0028] like Figure 1-4 As shown, based on the first embodiment, the present invention provides a technical solution for an energy identification type radiation dose monitoring device: a mounting plate 204 is fixedly connected to the top of the lifting frame 205 , and four sets of set holes 206 are opened on the mounting plate 204 .

[0029] like Figure 1-4 As shown, the tops of the four sets of thermoluminescent dosimeter bodies 203 are respectively sleeved on the four sets of sleeve holes 206 , and threaded holes 207 are opened on both the left and right sides of the top of the mounting plate 204 .

[0030] like Figure 1-4 As shown, two groups of fastening bolts 202 are provided on the top of the sealing plate 201 , and the bottoms of the fastening bolts 202 are respectively threadedly connected to the two groups of threaded holes 207 .

[0031] During implementation, by setting up the monitoring component 2, the fastening bolt 202 is rotated to separate it from the threaded hole 207, so that the sealing plate 201 can be removed, making it easier for personnel to disassemble and replace the thermoluminescent dosimeter body 203, further improving the convenience of radiation monitoring work.

[0032] In this embodiment, the controller is WSK-M (TH), the electric heater is DB-ⅡA, and the servo motor is 60M-R6430A5-E.

[0033] The advantages of this technical solution in practical applications include but are not limited to the following:

[0034] 1. The servo motor 105 can drive the monitoring component 2 to rise as a whole. Through the operation of multiple sets of thermoluminescent dosimeter bodies 203, radiation of different energies can be identified and monitored at the same time. The setting of the electric heater 104 can heat the thermoluminescent dosimeter body 203, which is convenient for personnel to observe and record the monitoring results. The overall structure is simple, stable, easy to use, and has good practicality.

[0036] In this technical solution, the controller 103 controls the servo motor 105 to drive the threaded rod 106 to rotate. The rotation of the threaded rod 106 drives the nut seat 107 to move, and the nut seat 107 drives the lifting frame 205 to rise. At this time, the four groups of thermoluminescent dosimeter bodies 203 are driven to rise to the upper side of the observation box 101, so that radiation of different energies can be identified and monitored. Then, the controller 103 controls the lifting frame 205 to descend into the observation box 101, and the sealing plate 201 blocks the lifting port 108. Then, the electric heater 104 works to heat the thermoluminescent dosimeter body 203, so that personnel can observe the brightness changes of the thermoluminescent dosimeter body 203 and record the monitoring results.
