Description

Technical Field

[0001] The invention relates to the technical field of sewage detectors, in particular to a portable light-sensitive radioactive sewage detector. Background Art

[0002] Radioactive wastewater refers to various wastewater discharged during nuclear power plants, nuclear fuel pre-processing, spent fuel post-processing, and the application of radioactive isotopes. The types and concentrations of radionuclides, acidity, and other chemical components contained in different wastewaters vary greatly. Nuclear power plants need to test the water quality after discharge to find out whether it meets the emission standards. During the test, they need to use equipment to collect wastewater.

[0003] Existing radioactive wastewater detectors are large in size and inconvenient to carry. They are easily interfered by external radioactive substances during detection, which affects the accuracy of detection. In addition, they do not have quantitative measuring tools and cannot achieve quantitative detection.

[0004] Therefore, in order to solve the above problems, a portable light-sensitive radioactive sewage detector is proposed. Summary of the invention

[0005] The object of the present invention is to provide a portable light-sensitive radioactive sewage detector, comprising an upper shell and a lower shell, wherein a crystal placement groove is provided at the bottom end of the upper shell, a crystal is arranged inside the crystal placement groove, a sealing gasket is provided above the crystal, a silicon photomultiplier tube is provided above the sealing gasket, the silicon photomultiplier tube is connected to a display screen through a connecting line, and a sewage detection groove is provided above the lower shell.

[0006] Preferably, the diameter of the sewage detection tank is larger than the diameter of the crystal.

[0007] Preferably, the upper shell and the lower shell are both made of copper-plated tungsten alloy.

[0008] Preferably, an internal thread is provided inside the upper part of the crystal placement groove, and an external thread is provided outside the upper part of the crystal, and the crystal is threadably connected to the internal thread provided on the upper part of the crystal placement groove via the external thread provided on the upper part.

[0009] Preferably, the display screen is arranged on the upper right side of the upper shell.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The upper shell and the lower shell of the present invention are both made of copper-plated tungsten alloy, which can shield external rays, prevent interference during sewage detection, and improve the accuracy of sewage detection. A sewage detection tank is opened inside the lower shell, and a certain amount of sewage can be placed in the sewage detection tank. When the instrument is placed in, some water inside will be squeezed out, so that the volume of sewage placed inside is constant each time, which is convenient for quantitative detection of water in different waters.

[0012] 2. The present invention sets a crystal and a silicon photomultiplier tube. After the crystal is placed in a sewage detection tank, the rays in the water hit the crystal to generate a light signal. The light signal is contacted by the silicon photomultiplier tube and then amplified to form an electric pulse signal. The electric pulse signal is transmitted to the display screen through a connecting line, effectively extracting the characteristics of the water acoustic pulse signal, thereby realizing the detection and analysis of specific components in the sewage.

[0013] 3. The upper shell and the lower shell of the present invention are small in size, simple to operate, easy to carry, and the numerical values ​​can be exported for subsequent viewing. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] As attached Figure 1 , 2 As shown, a portable light-sensitive radioactive sewage detector provided by the present invention includes an upper shell 1 and a lower shell 2. A crystal placement groove 11 is opened at the bottom end inside the upper shell 1. A crystal 3 is arranged inside the crystal placement groove 11. A sealing gasket 4 is arranged above the crystal 3. A silicon photomultiplier tube 5 is arranged above the sealing gasket 4. The silicon photomultiplier tube 5 is connected to a display screen 7 through a connecting line 6. A sewage detection groove 11 is opened above the inside of the lower shell 3.

[0020] Specifically, the diameter of the sewage detection tank 11 is larger than the diameter of the crystal 3 , so that the crystal 3 can be easily inserted into the sewage detection tank 11 .

[0021] Specifically, the upper shell 1 and the lower shell 2 are both made of copper-plated tungsten alloy, which can shield external rays, prevent interference during sewage detection, and improve the accuracy of sewage detection.

[0022] Specifically, the upper part of the crystal placement groove 21 is provided with an internal thread, and the upper part of the crystal 3 is provided with an external thread. The crystal 3 is threadably connected with the internal thread provided on the upper part of the crystal placement groove 21 through the external thread provided on the upper part.

[0023] Specifically, the display screen 7 is arranged on the upper right side of the upper housing 1 .

[0024] Working principle: When in use, separate the upper shell 1 from the lower shell 2, pour the sewage into the sewage detection tank 21, and then insert the crystal 3 into the sewage detection tank 21. A certain amount of sewage can be placed in the sewage detection tank 21. When the instrument is placed in, some water inside will be squeezed out, so that the volume of sewage placed inside each time is constant. After the crystal 3 is placed in the sewage detection tank 21, the rays in the water hit the crystal to generate a light signal. The light signal is contacted by the silicon photomultiplier tube and then amplified to form an electric pulse signal. The electric pulse signal is transmitted to the display screen through the connecting line, effectively extracting the characteristics of the water acoustic pulse signal, and realizing the detection and analysis of specific components in the sewage. Since the upper shell 1 and the lower shell 2 are both made of copper-plated tungsten alloy, they can shield external rays, prevent interference during sewage detection, and improve the accuracy of sewage detection.
