Embodiment
A kind of gamma-ray detection apparatus as shown in Figure 1 comprises casing 1, and big lead block 15 is housed in the casing, in the eccentric orfice of big lead block little lead block 16 is installed, and the source pigtail is placed in the eccentric orfice of little lead block.Little lead block drives the switching that it rotates the turnover of realization source by reducing motor 13 by motor gear 14.Prolong post 10 with the concentric open column that links to each other of little lead block and be the prolongation of little lead block, at one section with the little lead block gear 12 of gearcutter making with motor gear 14 identical moduluses.At casing one side loader seat 4, can be used as remote control circuit and battery case simultaneously.There are left end cap 2 and right end cap 18 in the casing both sides.In left end cap 2, be equipped with from lock slide 5, pin 6, unlock button 3, self-locking sunk screw 8 and self-locking sliding block spring 24, outside left end cap 2, also be equipped with and change source joint 7.In right end cap 18, be equipped with and change source button 19, change source slide block 20, change source sunk screw 21 and change source spring 25.In prolonging post 10, hose connector 11 is housed.A side is equipped with control pallet 27 in casing, and magnetictrip 22 is housed on it, and electromagnetism pin 23 and electromagnetism pin spring 26 are arranged in the magnetictrip.
A kind of gamma-ray detection apparatus; comprise casing; big lead block and little lead block are housed in the casing; the source of harness radioactive source is distinguished in the little lead block; and by its rotation of reductor band; it is characterized in that: little lead block is positioned on the eccentric position of big lead block, and the source distinguishes on the eccentric position that is positioned at little lead block that the switching of radioactive source exposed state and guard mode is back and forth rotated for 180 ° by the little lead block of gear driven by reducing motor and realized.
The exposure in source and the switching of guard mode do not need the source pigtail is shaken out pig by the rotation of little lead block.
The source is distinguished by distinguishing that with the concentric source of little lead block passage reaches casing and is convenient to change the source outward.
Big lead block hole wall studs with stainless steel, and copper sheathing is possessed in the little lead block outside, and the relative motion between them is by oil lubrication.
Defectoscope one side is that protection mechanism one side is a control gear, reducing motor, DC charging battery, remote control circuit is housed, moves back pin assembly, locating device in control gear one side.
It is the magnetictrip of being controlled by safety switch that electromagnetism moves back pin assembly, and passage was distinguished in the magnetictrip latch source of blocking when safety switch disconnected, and little lead block can not be rotated; The magnetictrip latch was attracted to regain by electromagnet when safety switch was closed, and this moment, little lead block can rotate.
Locating device is to constitute by being fixed on two blocks of strong magnetic magnet on the end cap and the bar that is fixed on the pigtail passage of source.Two positions that bar contacts with two blocks of magnet are that the source exposes and the position of protecting.And magnet links to each other with the positive antidirection finding of remote control circuit, and bar links to each other with power cathode, and the circuit location is combined with mechanical positioning.
Push button is installed on casing.
In defectoscope control gear one side end cap interlocking gear is installed.
This gamma-ray detection apparatus, comprise casing, big lead block is housed in the casing, in the eccentric orfice of big lead block, little lead block is housed, the source pigtail is housed in the eccentric orfice of little lead block, its difference from prior art is: the little lead block of remote control circuit control motor drives rotates, and operating personnel can hold the turnover of telepilot Controlling Source pigtail beyond 50m.
Control gear comprises that motor, remote control circuit, magnet are spacing, electromagnetism moves back pin assembly etc., magnet is spacing to link to each other with the casing insulation and with the spacing line of remote control circuit, on the prolongation post of little lead block, fix a gag lever post, spacing magnet is restrained gag lever post in 180 ° and is back and forth rotated, run into the circuitry cuts that control circuit just turns to this behind the spacing magnet of a certain side when gag lever post, the motor stall, thus having realized that mechanical position limitation and circuit are spacing combines.Electromagnetism moved back the switch failure of pin assembly when power switch was closed, and the electromagnetism pin fixedly makes it not rotate little lead block.
Safety interlock is by the realization that matches of slide block in the lid and two pins crossing slide block.The source pigtail is blocked by slide block in normal use, and button A (among the figure 3) pushes motionless; Touch pin when changing source interface, pressing button A source pigtail is released, old source can be released; When drawing in new source, pin and button A will eject automatically when the source pigtail is appeared certain distance, and the source pigtail is pinned.
