Embodiment 1

[0027] see figure 1 and figure 2 , the present invention provides a verification device for an electromagnetic radiation detector, which includes a base 1 fixedly arranged on the ground in a detection room, a radiation generator is arranged on the base 1, and the radiation is emitted by manually modulating the radiation generator, and then the electromagnetic detector is used for detection. According to the result of the feedback of the tester, it is known whether the tester can work normally. The gantry 2 is arranged directly above the base 1, the top of the gantry 2 is fixedly connected to the vertical shaft 3, and the vertical shaft 3 is rotatably connected to the top casing 4. The vertical rotating shaft 3 is driven to rotate by the main motor arranged in the top casing 4;

[0028] A circular ring 5 is arranged between the two bottom ends of the gantry 2, and the two sides of the circular ring 5 are rotatably connected with the bottom end of the gantry 2 through a horizo...

Embodiment 2

[0039] On the basis of Embodiment 1, shaft rods are arranged on both sides of the box body 8, and the shaft rods are rotatably connected to the support rod 62 through bearings.

[0040] The bottom of the box body 8 is provided with a counterweight. The box body 8 can also maintain a vertical state when the device is rotated and detected by the counterweight.

Embodiment 3

[0042] On the basis of Embodiments 1 and 2, different from Embodiment 2, a stabilizing mechanism is provided on the lower side of the box body 8, and the stabilizing mechanism includes a connecting rod 9 vertically arranged below the box body 8, and the lower end of the connecting rod 9 is fixed. Connect the disc 10; the top of the connecting rod 9 is rotationally connected with the box body 8, and the connecting rod 9 is driven to rotate by a stabilizing mechanism motor arranged on the lower side of the quick search box body 8.

[0043] The stabilizing mechanism motor drives the disc 10 with a certain weight to rotate through the connecting rod 9, so that the box body 8 is more stable.

Abstract

The invention discloses an electromagnetic radiation detector verification device, and relates to the field of electromagnetic detection equipment. According to the technical scheme, the device comprises a base which is fixedly arranged on the ground of a detection room. A radiation generator is arranged on the base. A door-shaped frame is arranged exactly on the base. A vertical rotating shaft isfixedly connected on the top of the door-shaped frame. A circular ring is arranged between the two bottom ends of the door-shaped frame. The two sides of the circular ring are rotatably connected with the bottom ends of the door-shaped frame through a horizontal rotating shaft respectively. A support for positioning the electromagnetic detector is arranged on the circular ring. The device has thebeneficial effects that the device has a simple structure and low total cost. The detection environment is constructed by the artificial modulated radiation source, the whole detection process is simple and easy to operate, the real radiation detection method can be simulated, the multi-axis and multi-direction detection of the radiation source can be easily realized and the results fed back by the radiation detector are compared with the results of artificial modulation so as to verify the working state of the radiation detector.

Description

technical field [0001] The invention relates to the field of electromagnetic detection equipment, in particular to a verification device for an electromagnetic radiation detector. Background technique [0002] Electromagnetic waves (also known as electromagnetic radiation) are electric and magnetic fields that oscillate in phase and are perpendicular to each other and move in the form of waves in space. Their propagation direction is perpendicular to the plane formed by the electric and magnetic fields, effectively transferring energy and momentum. Electromagnetic radiation can be classified according to frequency, from low frequency to high frequency, including radio waves, microwaves, infrared rays, visible light, ultraviolet light, X-rays and gamma rays, etc. The electromagnetic radiation that can be received by the human eye has a wavelength between 380 and 780 nanometers and is called visible light. As long as the object itself has a temperature higher than absolute ze...
