Abstract
The utility model discloses a gamma ray flaw detector, which comprises a cylinder, a depleted uranium tank arranged in the cylinder, a source braid of a gamma ray radiation source and an extending control mechanism of the source braid. The source braid and the extending control mechanism of the source braid are both arranged in the depleted uranium tank. The rear end of the source braid is connected with a telescopic driving device of the source braid. The utility model can be effectively used for the industrial nondestructive flaw detection of [192]+IR, and can prevent operating personnel from being radiated and effectively prevent error operation. The utility model can be widely used in industries, such as electric power industry, chemical industry, pressure container industry, etc.
Description
The utility model relates to a kind of equipment defectoscope.
Existing gamma-ray detection apparatus is big to operating personnel's radiation dose, and maloperation easily takes place.
The purpose of this utility model is to provide a kind of effective protection operating personnel to avoid radiation, is difficult for producing the gamma-ray detection apparatus of maloperation.
Technical solution of the present utility model is:
A kind of gamma-ray detection apparatus, the difference of itself and prior art is: comprise cylindrical shell, adorn lean uranium tank in the cylindrical shell, the source pigtail of harness gamma-rays radioactive source in the lean uranium tank is gone back the loading of source pigtail and is stretched out control gear in the lean uranium tank, and pigtail rear end, source is connected with the flexible gearing of source pigtail.
The source pigtail is to be connect by the nodular sports association that depleted nuclear fuel is made to form.The source pigtail stretches out control gear and comprises rotation depleted uranium post, has source pigtail passage in the rotation depleted uranium post, rotation depleted uranium post front end dress steel ball stop means, and rotation depleted uranium post rear end is fixed with the helicla flute device, and the helicla flute device contacts with sliding pin on being contained in the source pigtail.The steel ball stop means comprises the steel ball fixed leg that steel ball is housed, and steel ball fixed leg outside dress steel ball sheath is adorned stage clip between steel ball fixed leg and steel ball sheath.Adorn locking device on the helicla flute device.Source pigtail security lock arrangement is equipped with in pigtail rear end, source.Cylindrical shell is adorned dust cap foremost.Cylindrical shell top dress handle, bottom dress footing.
The utility model can be effective to
192Industrial nondestructive examination is carried out in the Ir source, and the protection operating personnel avoid radiation, effectively prevent maloperation.Can be widely used in industries such as electric power, chemical industry, pressure vessel.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
A kind of gamma-ray detection apparatus comprises cylindrical shell 12, dress lean uranium tank 13 in the cylindrical shell 12, harness gamma-rays radioactive source in the lean uranium tank 13
192The source pigtail 11 of Ir17 is gone back the loading of source pigtail and is stretched out control gear in the lean uranium tank 13, pigtail 11 rear ends in source are connected with the flexible gearing 16 of source pigtail.
Source pigtail 11 is to be connect by the nodular sports association that depleted nuclear fuel is made to form.The source pigtail stretches out control gear and comprises rotation depleted uranium post 3, have source pigtail passage in the rotation depleted uranium post 3, rotation depleted uranium post 3 front ends dress steel ball stop means, rotation depleted uranium post 3 rear ends are fixed with helicla flute device 4, and helicla flute device 4 contacts with sliding pin 15 on being contained in source pigtail 11.The steel ball stop means comprises the steel ball fixed leg 14 that steel ball 9 is housed, steel ball fixed leg 14 outsides dress steel ball sheath 8,8 dress stage clips 6 of steel ball fixed leg 14 and steel ball sheath.Adorn locking device on the helicla flute device 4, locking device covers lock 5 by lifting and control lock 7 is formed.Lock 5 is covered in lifting can adopt automatic control mode.Source pigtail security lock arrangement 10 is equipped with in pigtail 11 rear ends in source.Cylindrical shell 12 is adorned dust cap 1 foremost.Cylindrical shell 12 tops dress handle 2, bottom dress footing 18.
Principle of work of the present utility model is: during use, open dust cap 1 and insert joint, steel ball sheath 8 is retreated, steel ball moves laterally, make channel widens and open, open to promote and cover lock 5, operating personnel are away from defectoscope, but this time by the flexible gearing 16 of source pigtail with the source pigtail slightly to reach, sliding pin 15 is moved, and drive 4 rotations of helicla flute device, thereby make 3 rotations of rotation depleted uranium post, source pigtail 11 enters the passage in the rotation depleted uranium post 3, and the source pigtail is sent forward.During withdrawal, reverse operating gets final product.
