Abstract

The invention discloses a neutron detection device capable of realizing accurate detection. The neutron detection device comprises a neutron emission source, a sample placement frame and a neutron imaging detector; the neutron imaging detector is arranged above the neutron emission source; the sample placement frame is arranged between the neutron emission source and the neutron imaging detector;the neutron detection device further comprises a rack; the neutron emission source, the sample placement rack and the neutron imaging detector are arranged on the rack; a first shielding tube is vertically arranged on an emission hole of the neutron emission source; a second shielding tube is vertically arranged on an incidence hole of the neutron imaging detector; the first shielding tube and thesecond shielding tube are arranged in an up-and-down telescopic mode; a marking mechanism is arranged on the second shielding tube; the marking mechanism comprises a driving air cylinder and a pressing ring; the pressing ring and the second shielding tube are coaxially and radially arranged at intervals; the driving air cylinder is fixedly connected to the second shielding tube; the driving air cylinder can drive the pressing ring to move up and down; the outer surface of the pressing ring is coated with a layer of sponge soaked with ink; and the sample placement frame can be adjusted in position in the front-back direction and the left-right direction.

Description

technical field [0001] The invention relates to the technical field of neutron detection equipment, in particular to a neutron detection device capable of accurate detection. Background technique [0002] Neutron detection is a non-destructive detection using the transmission of neutrons. The application of this detection method has brought great convenience to the detection of the internal area of ​​​​objects that cannot be observed by the human eye and cannot be touched, especially in the field of aviation. It is very necessary to detect the inside of the parts. If there are cavities or cracks inside the parts, it is easy to cause accidents and threaten people's personal safety. [0003] General neutron detection equipment is not suitable for detecting items with a large area. For items with a large area, it is difficult to reach the incident range of the neutron source, and there will be more interference during detection, and the detection accuracy is difficult to achiev...
