Problems solved by technology

[0003] At present, when carrying out the radioactive source counting evaluation of the gamma radiation monitor, the radioactive source is pasted and fixed on the probe of the gamma radiation monitor with special 3M tape, which is prone to fixed position deviation, and then the counting and evaluation results of the gamma radiation monitor impact; and if the radioactive source is not fixed stably, there is a risk of falling. Dropping and impacting will easily lead to damage to the airtightness of the sealed shell on the surface of the radioactive source, and radioactive contamination incidents will occur, threatening the life, health and safety of the staff. Quality deviations and safety hazards

Embodiment 1

[0022] see Figure 1 to Figure 6 , an adjustable radioactive source fixing device for a gamma radiation monitor, including a belt 10, a frame 6 and a rotating device 7, the belt 10 is composed of a fixed part 1001 and a movable part 1002, and the belt 10 is made of a wide strip of stainless steel with good toughness sheet; the fixed part 1001 is connected with the movable part 1002, the fixed part 1001 is provided with a radioactive source fixing device 11, and the radioactive source fixing device 11 is used to place the radioactive source; the two ends of the movable part 1002 are provided with racks, and the frame 6 adopts a high The frame 6 is made of high-strength stainless steel. The frame 6 is designed as a rectangular frame structure. A through groove is opened at the bottom to facilitate the installation of the fixed part 1001 of the belt 10. The fixed part 1001 and the movable part 1002 of the belt 10 are connected through the frame 6 so that the belt 10 is ring-shaped...

Embodiment 2

[0027] The difference between this embodiment 2 and embodiment 1 is that, see figure 1 , the baffle 1 is symmetrically provided with an adhesive sheet 2, the adhesive sheet 2 is made of soft material, setting two adhesive sheets 2 is conducive to respectively attaching to both sides of the probe head, and the form of the adhesive sheet 2 is beneficial to the application The shape of different probe heads; there are two vacuum nozzles 3 on the adhesive sheet 2, the vacuum nozzles 3 are connected to the vacuum generator 5 through the vacuum tube 4, the vacuum tube 4 is made of hose material, and the vacuum generator 5 is set on the baffle 1, when in use, first stick the adhesive sheet 2 to the head of the probe, and then turn on the vacuum generator 5, so that the vacuum nozzle 3 can suck the head of the probe tightly to prevent the probe from falling off, and further strengthen the function of the device on the probe. stability.

Abstract

The invention discloses an adjustable radiation source fixing device for gamma radiation monitor. The device comprises a belt, a frame and a rotating device. The belt is composed of a fixed part and amovable part. The fixed part is connected to the movable part in a fixing mode. The fixing part is provided with a radioactive source fixing device. The movable part is provided with racks at both ends. A partition board is arranged in the frame. The upper part of the partition board is provided with the rotating device. The rotating device is movably connected with the racks on the movable partof the belt. The lower part of the partition board is fixedly connected with the fixing part of the belt through a plurality of bolts. A limit baffle is arranged on the side of the frame. The limitingbaffle is fixedly connected with the frame in a right angle. According to the diameters of probes, the device can be fixed on different types of probes, and can be prevented from falling off. The stability of the device can be enhanced when fixed on the probes. The device can facilitate the radioactive source to be taken out and fixed from the device, and has strong practicability.

Description

technical field [0001] The invention belongs to the technical field of radiation instruments, in particular to an adjustable radioactive source fixing device for gamma radiation monitors. Background technique [0002] Numerous gamma radiation monitors are installed in the workshop and area of ​​the nuclear power plant, which are mainly used for regional gamma dose rate radiation monitoring. It is necessary to conduct annual regular counting and evaluation work on the probes of gamma radiation monitors every year. During the annual regular counting and evaluation work, The radioactive source is fixed at a specific position of the probe for detection, and the radioactive source is aimed at the probe. In this case, the gamma radiation monitor will generate a value. By comparing the last detection value, if the value difference exceeds the specified value of the program, it is judged that the probe exists. question. [0003] At present, when carrying out the radioactive source ...
