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. The connecting disc 10 ; the top end 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 at the lower side of the 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 a verification device for an electromagnetic radiation detector, which relates to the field of electromagnetic detection equipment. The technical proposal includes a base fixedly arranged on the ground of a detection room, a radiation generator is arranged on the base, a gantry is arranged directly above the base, and the door The top of the gantry is fixedly connected to the vertical shaft; a ring is arranged between the two bottom ends of the gantry, and both sides of the ring are respectively connected to the bottom of the gantry through a horizontal rotating shaft; Detector mount. The beneficial effects of the present invention are: the device has a simple structure and low overall cost; the detection environment is constructed by manually modulating the radiation source; Check, compare the result fed back by the radiation detector with the result of manual modulation, so as to verify the working status 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...
