Description

Technical Field

[0002] A high-purity germanium detector is a nuclear radiation detector made of germanium crystal. It can be stored at room temperature, but should be at the temperature of liquid nitrogen during operation. According to the shape of its sensitive volume, HpGe detectors can be divided into planar type and coaxial type. Planar detectors are mainly used to measure the nuclear radiation of medium- and high-energy charged particles, such as 220Mev α particles, 60Mev protons, and 10Mev electrons, and low-energy gamma rays with an energy of 300 - 600kev. The detection efficiency for gamma rays is not as good as that of NaI(Tl), but it has a higher energy resolution and plays an important role in the occasion of resolving complex gamma energy spectra. A nuclear radiation detector made of germanium crystal with an extremely high purity of less than 10 - 15 in impurity content. There are already large-volume high-purity germanium detectors with both high energy resolution and efficiency. The energy resolution for the 1332.5keV γ ray of 60Co can reach 1.70kev, and the detection efficiency relative to the NaI(Tl) crystal can reach more than 50%.

[0025] In this embodiment, when effective encapsulation is carried out, the driving cylinder 402 on the upper rack 401 outputs power to drive the output end to operate, so that the cross beam 403 runs to a suitable height. Then, the pneumatic telescopic plate 404 at one end of the cross beam 403 outputs power to drive the output end to operate, and then the hydraulic cylinder 405 outputs power to drive the output end to operate, so that the upper cover 406 is clamped on the top side of the trough-shaped top cover 302 to achieve a sealing effect.

[0026] The shock-absorbing mounting assembly 1 includes a cushion block 101, a shock absorber 102, a base plate 103, a trough-shaped block 104, a slotted frame 105, a sliding rod 106, an upper base plate 107, and a bolt duct 108. A shock absorber 102 is provided on the top side of the cushion block 101, and a base plate 103 assembled with bolts is provided on the top side of the shock absorber 102.

An upper base plate 107 for installing the bolt duct 108 is provided on the top side of the slotted frame 105.

[0027] In this embodiment, during use, the germanium can 2015 with the installation threaded pipe 2016 is placed on the top side of the mounting piece 2011, and then the cushion block 101 is placed at the processing location, so that the shock absorber 102 can achieve an effective shock-absorbing effect during the use of the equipment, thus achieving the effect of shock-absorbing treatment. The detection component 3 and the encapsulation mechanism 4 are effectively assembled and spliced through the trough-shaped block 104, the slotted frame 105, the sliding rod 106, and the upper base plate 107.

The double slot 201 is provided on the inner side of the trough-shaped block 104. A meshing gear set 203 connecting the output end of the output motor 202 is provided inside the double slot 201, and a lead screw set 204 is provided at the output end of the meshing gear set 203. The lead screw set 204 is threadedly connected to the slider 205, and a hinged base 206 is provided on the top side of the slider 205. A connecting rod 207 connected by hinge is provided above the hinged base 206.

[0029] In this embodiment, when it is necessary to position the pure germanium tank 2015, the output motor 202 below the double slot 201 outputs power to drive the output end to operate. After the output motor 202 outputs power, the meshing gear set 203 meshes and drives to operate. After the meshing gear set 203 meshes and drives, the lead screw set 204 spirally operates, and then the slider 205 moves in opposite directions. Under the mutual cooperation of the hinged base 206, the connecting rod 207, and the lifting substrate 208, the lifting substrate 208 drives the pure germanium tank 2015 to run to a suitable height.

[0030] On the top side of the connecting rod 207, there is a lifting substrate 208 connected by a hinge. Below both ends of the lifting substrate 208, there are sliding seats 209. On the inner top side of the lifting substrate 208, there is an electric rotating seat 2010, and on the output end of the electric rotating seat 2010, there is a carrying plate 2011. Above both ends of the lifting substrate 208, there are end-to-end frames 2012, and on the inner sides of both ends of the end-to-end frames 2012, there are robotic arms 2013 equipped with pneumatic clamps 2014. On the top side of the carrying plate 2011, there is a pure germanium tank 2015, and on the top side of the pure germanium tank 2015, there is a threaded connection pipe 2016.

[0031] In this embodiment, when positioning is required, the robotic arms 2013 on the inner sides of both ends of the end-to-end frames 2012 output and operate, and then the pneumatic clamp 2014 at one end of the robotic arm 2013 firmly clamps the pure germanium tank 2015. After clamping, the pure germanium tank 2015 can effectively achieve a stable effect.

[0032] The detection component 3 includes a receiving housing 301, a trough-shaped top cover 302, an inner content block 303, and an annular cover 304. The receiving housing 301 is arranged on the top side of the bolt duct pipe 108. On the top side of the receiving housing 301, there is a trough-shaped top cover 302. On the inner side of the receiving housing 301, there is an inner content block 303, and on the top side of the inner content block 303, there is an annular cover 304.

[0033] In this embodiment, when connection is required, the pneumatic clamp 2014 at one end of the robotic arm 2013 loosens the pure germanium tank 2015. After loosening, the output end of the electric rotating seat 2010 outputs power to drive the output end to operate, and then the carrying plate 2011 drives the pure germanium tank 2015 to rotate. Under the mutual cooperation of the pneumatic clamp 2014 and the robotic arm 2013, the threaded connection pipe 2016 above the pure germanium tank 2015 and the receiving housing 301 are effectively rotationally connected, so as to cooperate with the detection component 3 for effective use and operation.

[0034] The working principle of the mechanical control device for this high-purity germanium detector is as follows: When in use, the pure germanium tank 2015 with the installation threaded pipe joint 2016 is placed on the top side of the carrier sheet 2011, and then the cushion block 101 is used and placed at the processing location, so that the shock absorber 102 can achieve an effective shock absorption effect during the use of the equipment, thus achieving the effect of shock absorption treatment. And through the groove-shaped block 104, the grooved frame 105, the slide rod 106, and the upper substrate 107, the detection component 3 and the encapsulation mechanism 4 are effectively assembled and spliced. When positioning is required, the robotic arms 2013 on the inner sides of both ends of the end-to-end frame 2012 are used to output and operate, so that the pneumatic clamp 2014 at one end of the robotic arm 2013 firmly clamps the pure germanium tank 2015. After clamping, the pure germanium tank 2015 can effectively achieve a stable effect. When effective encapsulation is carried out, the driving cylinder 402 on the upper frame 401 outputs power to drive the output end to operate, so that the cross beam 403 runs to a suitable height. And the pneumatic expansion plate 404 at one end of the cross beam 403 outputs power to drive the output end to operate, so that the hydraulic cylinder 405 then outputs power to drive the output end to operate, so that the upper cover 406 is clamped on the top side of the groove-shaped top cover 302 to achieve a sealing effect. When it is necessary to make the pure germanium tank 2015 in place, the output motor 202 below the double groove 201 outputs power to drive the output end to operate. After the output motor 202 outputs power, the meshing gear set 203 can be meshed and driven to operate. After the meshing gear set 203 is meshed and driven, the lead screw set 204 runs in a spiral manner, so that the slider 205 runs in an opposite direction. Under the mutual cooperation of the articulated base 206, the connecting rod 207, and the lifting substrate 208, the lifting substrate 208 drives the pure germanium tank 2015 to run to a suitable height. When connection is required, the pneumatic clamp 2014 at one end of the robotic arm 2013 loosens the pure germanium tank 2015. After loosening, the output end of the electric rotating seat 2010 outputs power to drive the output end to operate, so that the carrier sheet 2011 drives the pure germanium tank 2015 to rotate. Under the mutual cooperation of the pneumatic clamp 2014 and the robotic arm 2013, the threaded pipe joint 2016 above the pure germanium tank 2015 and the receiving housing 301 are effectively rotationally connected, so as to cooperate with the detection component 3 for effective use and operation.
