Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to nuclear radiation testing equipment. Background Art

[0002] Nuclear radiation detector is also called radiation detector; there are radiation alarms on the market. Radiation detectors are instruments without dose display, which can only remind the wearer whether the radiation in the current site exceeds the standard. As for the specific radiation dose, it is difficult to determine; radiation dose detector, this instrument can not only alarm, but also clearly display the radiation dose value of the current site. The main component of nuclear radiation detector is Geiger counter, which determines that nuclear radiation detector can not only detect nuclear radiation, but also detect X\Y\B rays, etc. Therefore, some manufacturers also call it X-ray dose alarm, or X\Y ray dose alarm.

[0003] However, some existing nuclear radiation detectors are not portable enough when used. Most radiation detection devices include a radiation detector and a detection probe used in conjunction with it. Most of the detection probes can be raised, lowered and rotated, but the probes are mostly exposed to the outside. When not in use, the detection probes are exposed to the outside for a long time and are easily damaged. Utility Model Content

[0022] Furthermore, the technical solutions of the various embodiments of the present invention may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] The utility model provides a nuclear radiation testing device.

[0024] like Figure 1-2As shown, the nuclear radiation testing equipment provided by the embodiment of the utility model includes an equipment housing 10, a test tube 20 installed on the equipment housing 10, and a circuit board arranged in the equipment housing 10. The side of the equipment housing 10 is provided with a receiving groove 11 for accommodating the test tube 20. The first end of the test tube 20 is rotatably mounted on the equipment housing 10 so that the test tube 20 can switch between two states of being accommodated in the receiving groove 11 and rotating to extend out of the receiving groove 11. The second end of the test tube 20 can be used to detect a radiation source.

[0025] In this embodiment, when nuclear radiation detection is required, the test tube 20 can be taken out of the receiving tank 11 for nuclear radiation testing. After the test is completed, the test tube 20 can be stored in the receiving tank 11 to protect the test tube 20 and reduce the possibility of damage to the test tube 20 during carrying.

[0026] Among them, please refer to Figure 2 The device housing 10 includes a top cover 12 and a bottom cover 13. The top cover 12 can be covered on the bottom cover 13 to form a receiving cavity 14. The circuit board is received in the receiving cavity 14 and is electrically connected to the test tube 20. In this embodiment, the top cover 12 and the bottom cover 13 are detachably connected and can be connected by a snap-on structure or a screw-on structure to improve stability.

[0027] Specifically, a rotating disk 40 is provided on the bottom plate, and the first end of the test tube 20 is connected to the rotating disk 40. A rotating shaft 15 is provided on the bottom cover 13, and the rotating shaft 15 is provided at the axis of the rotating disk 40 so that the rotating disk 40 can rotate around the rotating shaft 15. In this embodiment, the rotating disk 40 can rotate around the rotating shaft 15, thereby changing the state of the test tube 20. Among them, the rotating connection between the rotating shaft 15 and the rotating disk 40 can be set to a damped rotation mode, so that the test tube 20 will not rotate easily after rotating, so that the working state can be maintained.

[0028] Furthermore, a connecting column 41 is provided on the outer wall surface of the rotating disk 40, and a connecting hole 42 is provided in the connecting column 41, and the first end of the test tube 20 is clamped in the connecting hole 42. In this embodiment, the test tube 20 is installed by the connecting column 41 to improve the stability of the test tube 20.

[0029] Specifically, the test tube 20 includes a Geiger-Mueller counter 22 and a stainless steel tube 21 disposed outside the Geiger-Mueller counter 22, and the outer wall surface of the stainless steel tube 21 is disposed in the connection hole 42. It is understandable that the present application does not improve the specific test principle of nuclear radiation, and the existing Geiger-Mueller counter 22 can be directly used. At the same time, the specific principle of the electrical connection between the Geiger-Mueller counter 22 and the circuit board and the display of the radiation degree of nuclear radiation on the display screen 31 on the main board 30 also belongs to the prior art, which will not be repeated here. By setting an exposure hole 16 on the top cover 12, the display screen 31 on the main board 30 is set at the exposure hole 16. When the test tube 20 is extended into the soil, food or water source to be tested for radiation source, the nuclear radiation data detected by the Geiger-Mueller counter 22 will be displayed on the display screen 31 for the user to view.

[0030] In the above embodiment, the outer wall surface of the bottom plate is recessed inward to form a taking groove 17 connected to the receiving groove 11. By providing the taking groove 17, it is more convenient for the user to take the test tube 20 out of the receiving groove 11, thereby improving convenience.

[0031] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
