[0002] Tritium and carbon-14 are two radioactive nuclides that are highly concerned when released into the environment by nuclear reaction equipment. Among them, tritium has a strong isotope exchange capacity and a half-life of 12.6 years. Most of the tritium released into the environment will eventually form tritium water-water vapor, and enter the water cycle together with ordinary water, so it is easy for humans to be radiated. Carbon-14 participates in the global carbon cycle and causes global warming. Therefore, in nuclear reaction work, it is of great significance to monitor the content of tritium and carbon-14 in the exhaust gas. Before monitoring the content of tritium and carbon in the gas, it is usually necessary to sample the tritium and carbon in the gas through a tritium-carbon sampling device, specifically, the exhaust gas containing tritium HTO and 14CO2 is absorbed by the absorption unit of the tritium-carbon sampling device.

The plurality of bottle caps 32 are mounted on the opening and closing actuator assembly.

[0036] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: the absorption device 20 of the above-mentioned solution is applied to the tritium carbon sampling device 100, and is specifically used to be installed in the accommodating area of ​​the tritium carbon sampling device 100. During normal operation, the absorption bottle 30 is installed on the corresponding loading assembly 212, and the bottle cap 32 is installed on the opening and closing execution assembly and is arranged one by one with the bottle body 31. The power source 41 drives the opening and closing execution assembly to move toward the bottle body 31, thereby driving the bottle cap 32 to cover the bottle mouth of the bottle body 31 and press the bottle mouth to seal, thereby completing the synchronous installation of multiple absorption bottles 30; when the absorption bottle 30 needs to be replaced after working for a period of time, the power source 41 is controlled to drive the opening and closing execution assembly to drive the bottle cap 32 away from the bottle body 31, and then the bottle body 31 is removed from the loading assembly 212. Compared with the prior art, the present solution can simultaneously realize the installation and disassembly of the bottle bodies 31 and bottle caps 32 of multiple absorption bottles 30. The assembly and disassembly operations are convenient and highly automated, which reduces the labor intensity of workers and greatly improves the efficiency of taking and placing the absorption bottles 30. There is no need to frequently twist the threaded structure, and the sealing of the absorption bottles 30 will not be affected by the problem of thread slippage.

[0037] Optionally, in the present application, four absorption bottles 30 are specifically provided, and correspondingly, four loading assemblies 212 are also provided.

[0038] Please continue reading Figure 2 and Figure 3 On the basis of the above embodiment, the top surface of the base 211 is concavely formed with a plurality of mounting grooves 211a, and the loading components 212 are inserted into the mounting grooves 211a one by one, and at least part of the bottle body 31 is inserted into the mounting grooves 211a. Therefore, the loading components 212 and the bottle body 31 can both be limited by the groove wall of the mounting groove 211a, thereby ensuring a stable installation and not easily tipping over due to force when the bottle cap 32 and the bottle body 31 are closed or separated.

[0039] For example, in the present application, the absorption bottle 30 is a cylinder, and accordingly the loading assembly 212 and the mounting groove 211 a are also set as circular hole grooves, and the diameter of the circular hole groove is slightly larger than the diameter of the bottle body 31 and the loading assembly 212 .

[0040] In some optional embodiments, the loading assembly 212 includes a fixed block 212a, an elastic member 212b and a support block 212c, the fixed block 212a is arranged at the bottom of the mounting groove 211a, the support block 212c is arranged above the fixed block 212a, and the support block 212c supports the bottle body 31, one end of the elastic member 212b is connected to the fixed block 212a, and the other end of the elastic member 212b is connected to the support block 212c.

[0041] In this way, the elastic member 212b enables the support block 212c to form a floating flexible connection with the fixed block 212a. On the one hand, even if there is an alignment and installation error between the bottle body 31 and the bottle cap 32, the bottle body 31 can achieve adaptive alignment, so that it can be reliably covered with the bottle cap 32; on the other hand, when the opening and closing actuator drives the bottle cap 32 to cover the bottle mouth of the bottle body 31, the elastic member 212b is compressed and provides an elastic thrust to the bottle body 31 through the support block 212c, so that the bottle mouth of the bottle body 31 can be more tightly covered with the bottle cap 32, so as to improve the sealing performance.

[0042] On the basis of the above embodiment, the bottle mouth of the bottle body 31 is provided with a first inclined surface, and the bottle cap 32 is provided with a second inclined surface, and the second inclined surface is sealed and wedged with the first inclined surface, so as to further improve the sealing and stability of the assembly of the bottle body 31 and the bottle cap 32, and prevent the radioactive material collected in the bottle from leaking.

[0043] Alternatively, a sealing ring may be installed at the bottle mouth of the bottle body 31 and / or on the bottle cap 32 to improve the sealing performance of the bottle cap 32 and the bottle body 31 after they are covered.

[0044] Please continue reading Figure 2 and Figure 3 Furthermore, a support surface is provided on the side of the support block 212c away from the fixing block 212a, and a positioning groove 2121c is formed in the support surface, and the bottom of the bottle body 31 is inserted into the positioning groove 2121c. The positioning groove 2121c has a positioning effect on the bottle body 31, thereby further improving the installation stability of the bottle body 31 on the loading assembly 212.

[0045] In addition, an introduction structure is provided at the edge of the notch of the positioning groove 2121 c, and the introduction structure is used to make it easier for the bottom of the bottle body 31 to be inserted into the positioning groove 2121 c.

[0046] On the basis of any of the above embodiments, the opening and closing actuator assembly includes a transmission plate 42 and a mounting plate 43, the mounting plate 43 is mounted on the transmission plate 42, the mounting plate 43 is provided with a plurality of mounting positions, each mounting position is correspondingly provided with a bottle cap 32, and the transmission plate 42 is drivingly connected with the power source 41. The transmission plate 42 indirectly connects the mounting plate 43 with the power source 41, so that the power output of the power source 41 can be transmitted to the mounting plate 43, thereby driving the bottle cap 32 mounted on the mounting plate 43 to move closer to or away from the bottle body 31. Since the mounting plate 43 is provided with a plurality of mounting positions, each mounting position can be provided with a bottle cap 32, so that a plurality of bottle caps 32 can be simultaneously covered or separated from the corresponding bottle body 31, and compared with the traditional method of installing or removing the bottle cap 32 by screwing the thread one by one by manpower, the working efficiency is greatly improved.

[0047] Specifically, a clamp unit is provided in the installation position, and the clamp unit is clamped and fixed with the bottle cap 32. The bottle cap 32 can be clamped and fixed by the clamp unit to prevent the bottle cap 32 from loosening and falling. At the same time, the clamp unit also facilitates the installation and removal of the bottle cap 32.

[0048] For example, the clamp unit may be any one of a spring clamp, a suction cup, a magnetic suction piece, etc., which may be flexibly selected according to actual needs and is not particularly limited herein.

[0049] Optionally, the power source 41 in the present application is specifically a lifting drive device, for example, a power structure combination of a motor and a screw nut can be adopted.

[0050] In some other optional embodiments, the opening and closing power mechanism 40 further includes a first position sensor and a second position sensor, which are installed in the motion path of the opening and closing actuator, and the first position sensor corresponds to the position of the opening and closing actuator farthest from the bottle body 31, and the second position sensor corresponds to the position of the opening and closing actuator closest to the bottle body 31. The first position sensor and the second position sensor can detect the two extreme positions of the opening and closing actuator for opening and closing the bottle body 31, thereby controlling the power source 41 to accurately output and stop power, and avoiding the problem of collision due to excessive movement.

[0051] Optionally, the first position sensor and the second position sensor may be any one of an infrared sensor, a laser sensor, and the like.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
