The solution sample conveying devices used in domestic nuclear chemical plants are generally bottle-shaped structures, relying on air flow pressure differences for transmission within pipelines. However, the solution sample conveying devices currently used have problems such as high processing costs, difficult sampling operations, and poor sealing due to design reasons such as structural materials. Therefore, this patent designs a new solution sample conveying device that solves the above-mentioned defects while meeting the requirements of radioactive sampling. Summary of the invention

[0032] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0033] The terms used in one or more embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit one or more embodiments of the present application. The singular forms of "a", "said" and "the" used in one or more embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used in one or more embodiments of the present application refers to and includes any or all possible combinations of one or more associated listed items.

[0034] It should be understood that, although the terms first, second, etc. may be used to describe various information in one or more embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0035] A radioactive solution sample delivery device comprises a bottle cap 1, a bottle body 2 and a bottle stopper 3. There is no metal shell and it is formed in one step by injection molding. After assembly, sampling can be carried out by injecting solution at the position of the bottle stopper. There are special bosses on the bottle cap 1 and the bottle body 2, which can be conveniently clamped and taken remotely. The bottle body 2 and the bottle cap 1 are connected by a sealing thread with a self-locking and anti-loosening function. The bottle stopper 3 is connected to the bottle cap 1 by a card slot, and the sealing is achieved by the elastic deformation of the rubber.

[0036] In this design example, Figure 1 As shown, in order to realize pipeline transmission, the overall shape of the radioactive solution sample delivery device is designed to be cylindrical. The bottom of the bottle cap 1 and the bottle body 2 are designed with a bottle cap polygonal edge 11 and a bottle body polygonal edge 21 with an inscribed circle as the base and central symmetry, which is convenient for clamping and fixing during the sampling process. There is a diameter change A22 in the middle of the bottle body 2 to facilitate the horizontal or vertical clamping of remote tools. The surface of the bottle body 2 and the bottle cap 1 are rounded to avoid the equipment from getting stuck during the transmission and inspection of the conveying device.

[0037] In this design example, Figure 2 , 3As shown, the thread of the radioactive solution sample delivery device has a self-locking function. The matching parts of the bottle body thread 23 and the bottle cap thread 12 are designed with convex points and grooves for snapping to prevent the relative displacement of the matching surfaces of the threads after the device is transmitted and collided. A circle of annular reducers is designed below the threads of the bottle body 2 and the bottle cap 1, which is manifested as a continuous or intermittent boss. The bottle body boss 24 is above the bottle cap boss 13. After assembly, the bottle body boss 24 presses the bottle cap boss 13 to prevent it from axial displacement. The bottle cap and bottle body are locked by the above two interlocking parts to avoid solution leakage and contamination caused by thread matching failure. The pressure difference generated by the matching gap between the bottle body thread 23 and the bottle cap thread 12 is sealed. The stroke of the bottle cap thread 12 is 1 / 3 of the circumference, which is convenient for opening the cover and reduces the difficulty of remote operation.

[0038] In this design example, Figure 4 , 5 As shown, the shapes of the bottle stopper 3 and the bottle cap 1 match each other. The diameter of the matching section 31 at the upper end of the bottle stopper is slightly smaller, and the annular groove 14 of the bottle cap is cut off to facilitate the installation of the bottle stopper 3. The diameter of the matching part 32 between the bottle stopper and the bottle mouth is slightly larger to facilitate sealing. A concave hole 33 is provided at the bottom of the bottle stopper 3 for easy puncture. There is no need to open the cover during the sampling operation. A needle can be used to pierce from the middle of the bottle stopper 3 to inject the sample into the device, thereby simplifying the operation process.

[0039] In this design example, Figure 6 As shown, the bottle body 2 has a diameter change B25 at the bottle mouth, which provides better support for the bottle plug 3 and prevents the bottle plug 3 from being pressed into the bottle body 2 by the needle.

[0040] The composition and coordination relationship of the radioactive solution sample delivery device are as follows: Figure 7 shown.

[0041] In this design example, the material of the bottle cap 1 and the bottle body 2 can be selected from one or a mixture of polytetrafluoroethylene, polyimide, polystyrene, polyethylene, polypropylene and the like. The material of the bottle stopper 3 can be selected from rubber elastomers such as fluororubber and silicone rubber.

[0042] In this design example, the processing method of the radioactive solution sample delivery device is injection molding.
