Description

Technical Field

[0001] This utility model relates to the field of deuterium concentration regulation technology, and in particular to a deuterium concentration balancing and interconnection mechanism. Background Technology

[0002] In the field of optical fiber manufacturing, deuterium treatment is a key process to improve the hydrogen loss resistance of optical fibers. By placing the optical fiber in a closed environment containing deuterium, deuterium atoms combine with defect sites in the optical fiber material, which can effectively suppress the damage of hydrogen to the transmission performance of optical fibers during subsequent use. After the optical fiber is treated with deuterium, the mixed gas containing deuterium and nitrogen is discharged through the exhaust pipe, which is a waste of deuterium. Therefore, it is necessary to interconnect and utilize the remaining deuterium in each deuterium cabinet. However, most existing deuterium concentration balance interconnection mechanisms still have problems that need to be solved.

[0003] In the existing technology, most deuterium concentration balance inter-connection mechanisms use welding or flange fixed connections for the pipelines. The pipeline connection and maintenance efficiency is low. When it is necessary to clean the inner wall of the pipeline, it is necessary to use professional tools such as welding machines and heavy wrenches to disassemble it. A single maintenance often takes several hours, which is very troublesome. This leads to the extended downtime of the deuterium gas holder and affects work efficiency. Therefore, it is urgent to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deuterium concentration balance and interconnection mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A deuterium concentration balancing and interconnection mechanism includes several deuterium gas holders. A first balancing pipeline is fixedly connected to one side of each of two adjacent deuterium gas holders. A second balancing pipeline is provided on the side of the first balancing pipeline away from the deuterium gas holder. The same first pneumatic valve is fixedly connected to the side of two adjacent second balancing pipelines that are close to each other. Four positioning rods are fixedly connected to the side of the second balancing pipeline near the first balancing pipeline. Four positioning grooves adapted to the positioning rods are opened on the side of the first balancing pipeline near the second balancing pipeline. Two fixing blocks are fixedly connected to the outer wall of the second balancing pipeline near the first balancing pipeline. A circular hole is opened on each fixing block, and a circular rod is placed inside the circular hole. An L-shaped plate is fixedly connected to the top of the circular rod, and a limit rod is fixedly connected to the bottom of the L-shaped plate. A limit plate is sleeved on the limit rod, and the limit rod is slidably connected to the limit plate. The limit plate is fixedly connected to the first balancing pipeline, and a return spring is sleeved on the limit rod. The return spring is located at the bottom of the limit plate. Due to the use of fixing blocks and circular holes… The technique of using a round rod to restrict the position between the second and first balancing pipes is as follows: inserting the round rod into the round hole restricts the position between the second and first balancing pipes, preventing them from separating. Removing the round rod from the round hole releases the restriction on the second and first balancing pipes, allowing them to be separated. The second balancing pipe can then be disassembled for cleaning. This effectively solves the problem mentioned in the background art, where most existing deuterium concentration balancing interconnection mechanisms use welding or flanged connections, resulting in low efficiency in pipe connection and maintenance. When cleaning the inner wall of the pipes is required, specialized tools such as welding machines and heavy-duty wrenches are needed for disassembly, often taking several hours per maintenance session. This cumbersome operation leads to prolonged downtime of the deuterium gas holder, affecting work efficiency. This technique effectively simplifies the disassembly and assembly steps, reduces operational difficulty, replaces traditional welding or flanged connections, and makes maintenance work more efficient and convenient.

[0006] As a further embodiment of this utility model, the tops of the two L-shaped plates are fixedly connected to the same handle.

[0007] As a further embodiment of this utility model, a first measuring pipe is fixedly connected to the outer wall of the second balancing pipe. The first measuring pipe is connected to the second balancing pipe. The output end of the first measuring pipe is fixedly connected to the second measuring pipe. A vacuum pump is installed on the second measuring pipe. The two second measuring pipes at the same end are fixedly connected to the same deuterium gas fixed measuring instrument on the side that is close to each other.

[0008] As a further embodiment of this utility model, a first suction pipe is fixedly connected to the back of the deuterium gas holder, a second pneumatic valve is fixedly connected to the output end of the first suction pipe, a second suction pipe is fixedly connected to the output end of the second pneumatic valve, several second suction pipes are fixedly connected to the same third suction pipe, a vacuum pump is provided at the output end of the third suction pipe, the input end of the vacuum pump is fixedly connected to the output end of the third suction pipe, an inlet pipe is fixedly connected to the output end of the vacuum pump, and the inlet pipe is fixedly connected to one of the deuterium gas holders and communicates with the deuterium gas holder.

[0009] As a further embodiment of this utility model, the second balancing pipeline is fixedly connected to a sealing ring on the side near the first balancing pipeline, and the first balancing pipeline has a circular groove on the side near the second balancing pipeline, and the sealing ring is adapted to the circular groove.

[0010] As a further embodiment of this utility model, a support is fixedly connected to the bottom of the vacuum pump, and a deuterium gas holder is fixedly connected to the support.

[0011] The beneficial effects of this utility model are as follows: By employing a combination of a fixing block, a circular hole, and a circular rod to restrict the position between the second and first balancing pipelines, inserting the circular rod into the circular hole effectively restricts their position, preventing separation. Removing the circular rod from the circular hole releases the restriction, allowing for separation of the second and first balancing pipelines. The second balancing pipeline can then be disassembled for cleaning. This effectively solves the problem mentioned in the background art, where most existing deuterium concentration balancing interconnection mechanisms use welding or flanged connections, resulting in low pipeline connection and maintenance efficiency. Furthermore, cleaning the inner wall of the pipeline requires specialized tools such as welding machines and heavy-duty wrenches, often taking several hours per maintenance session, causing significant inconvenience and prolonged downtime for the deuterium gas holder, thus impacting work efficiency. This technology simplifies disassembly and assembly, reduces operational difficulty, and replaces traditional welding or flanged connections, making maintenance more efficient and convenient.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-7The deuterium concentration balancing and interconnection mechanism includes several deuterium gas holders 1. A first balancing pipeline 2 is fixedly connected to one side of each pair of adjacent deuterium gas holders 1. A second balancing pipeline 3 is provided on the side of the first balancing pipeline 2 away from the deuterium gas holder 1. The same first pneumatic valve 4 is fixedly connected to the side of each pair of adjacent second balancing pipelines 3 that is close to each other. Four positioning rods 7 are fixedly connected to the side of the second balancing pipeline 3 that is close to the first balancing pipeline 2. Four positioning points adapted to the positioning rods 7 are provided on the side of the first balancing pipeline 2 that is close to the second balancing pipeline 3. In the groove 8, the second balancing pipeline 3 has two fixing blocks 9 fixedly connected to the outer wall of one end near the first balancing pipeline 2. The fixing blocks 9 have circular holes 901, and a circular rod 10 is installed inside the circular holes 901. An L-shaped plate 11 is fixedly connected to the top of the circular rod 10, and a limiting rod 12 is fixedly connected to the bottom of the L-shaped plate 11. A limiting plate 13 is fitted onto the limiting rod 12, and the limiting rod 12 is slidably connected to the limiting plate 13. The limiting plate 13 is fixedly connected to the first balancing pipeline 2, and a return spring 14 is fitted onto the limiting rod 12. The return spring 14 is located at the bottom of the limiting plate 13. This invention employs a technique that uses a combination of a fixing block, a circular hole, and a circular rod to restrict the position between the second and first balancing pipelines. Inserting the circular rod into the circular hole restricts the position between the two pipelines, preventing separation. Removing the circular rod from the hole releases the restriction, allowing for separation and cleaning of the second balancing pipeline. This effectively solves the problem presented in the background section where most existing deuterium concentration balancing interconnection mechanisms use welding or flange connections, resulting in low efficiency in pipeline connection and maintenance. Furthermore, cleaning the inner wall of the pipeline requires specialized tools such as welding machines and heavy-duty wrenches, often taking several hours per maintenance session, leading to prolonged downtime for the deuterium gas holder and impacting work efficiency. This invention simplifies the disassembly and assembly process, reduces operational difficulty, and replaces traditional welding or flange connections, making maintenance more efficient and convenient.

[0016] In this embodiment, the tops of the two L-shaped plates 11 are fixedly connected to the same handle 15.

[0017] In this embodiment, a first measuring pipe 16 is fixedly connected to the outer wall of the second balancing pipe 3. The first measuring pipe 16 is connected to the second balancing pipe 3. The output end of the first measuring pipe 16 is fixedly connected to a second measuring pipe 17. The two second measuring pipes 17 at the same end are fixedly connected to the same deuterium gas fixed measuring instrument 18 on the side that is close to each other. After the deuterium gas treatment is completed, the deuterium gas fixed measuring instrument 18 is started and the first pneumatic valve 4 is opened. The pump between the deuterium gas fixed measuring instrument 18 and the first pneumatic valve 4 is powered on and starts to work, drawing the deuterium gas mixture in the deuterium gas cabinet 1 into the measuring instrument for measurement. The deuterium gas fixed measuring instrument 18 displays the actual deuterium gas concentration in the cabinet.

[0018] In this embodiment, a first extraction pipe 19 is fixedly connected to the back of the deuterium gas holder 1. A second pneumatic valve 20 is fixedly connected to the output end of the first extraction pipe 19. A second extraction pipe 21 is fixedly connected to the output end of the second pneumatic valve 20. Several second extraction pipes 21 are fixedly connected to the same third extraction pipe 22. A vacuum pump 23 is installed at the output end of the third extraction pipe 22. The input end of the vacuum pump 23 is fixedly connected to the output end of the third extraction pipe 22. An inlet pipe 25 is fixedly connected to the output end of the vacuum pump 23. The inlet pipe 25 is fixedly connected to one of the deuterium gas holders 1. The inlet pipe 25 is connected to the deuterium gas holder 1. When the second pneumatic valve 20 is opened, the pneumatic vacuum pump 23 is activated. The vacuum pump 23 balances and circulates the deuterium concentration in each deuterium gas holder 1. After 40 minutes, the vacuum pump 23 stops working, the second pneumatic valve 20 is closed, and the balancing and circulation is completed.

[0019] In this embodiment, a sealing ring 5 is fixedly connected to the second balancing pipe 3 on the side close to the first balancing pipe 2, and a circular groove 6 is opened on the side of the first balancing pipe 2 close to the second balancing pipe 3, and the sealing ring 5 is adapted to the circular groove 6.

[0020] In this embodiment, a support platform 24 is fixedly connected to the bottom of the vacuum pump 23, and the support platform 24 is fixedly connected to the deuterium gas holder 1.

[0021] Working principle: After deuterium gas treatment is completed, the fixed deuterium gas measuring instrument 18 is started and the first pneumatic valve 4 is opened. The pump between the fixed deuterium gas measuring instrument 18 and the first pneumatic valve 4 is energized and starts working, drawing the deuterium gas mixture in the deuterium cabinet 1 into the measuring instrument for measurement. The fixed deuterium gas measuring instrument 18 displays the actual deuterium gas concentration in the cabinet. Once the concentration is balanced, the second pneumatic valve 20 is opened, and the vacuum pump 23 is started, drawing the deuterium gas from each deuterium cabinet 1. The deuterium gas is then injected into another cabinet through the first extraction pipeline 19, the second pneumatic valve 20, the second extraction pipeline 21, the third extraction pipeline 22, the vacuum pump 23, and the inlet pipeline 25. Within a deuterium gas holder 1, the gas is interconnected through a first balancing pipe 2 and a second balancing pipe 3. A vacuum pump 23 circulates the deuterium gas concentration within each deuterium gas holder 1 to maintain equilibrium. After 40 minutes, the vacuum pump 23 stops, and the second pneumatic valve 20 is closed, completing the balancing process. During assembly, pulling the handle 15 raises it, causing the L-shaped plate 11 to rise. The L-shaped plate 11 then moves the limiting rod 12 along the limiting plate 13. The limiting rod 12 moves along the limiting plate 13 to ensure stability during movement. The limiting rod 12 then compresses the return spring 14. When the L-shaped plate 11 retracts and rises, it also drives the round rod 10 to rise, placing the second balance pipe 3 on one side of the first balance pipe 2. The positioning rod 7 is inserted into the positioning groove 8 to position the second balance pipe 3 and the first balance pipe 2. The sealing ring 5 is inserted into the round groove 6, and the sealing ring 5 is squeezed to deform, causing it to fit tightly against the first balance pipe 2, thus providing a certain degree of sealing. After positioning is complete, the round rod 10 is coaxial with the round hole 901. Releasing the handle 15 causes the retracted return spring 14 to extend, allowing the limit rod 12 to descend. The limit rod 12 then drives the L-shaped plate 11 to descend. The forming plate 11 will cause the round rod 10 to descend, inserting the round rod 10 into the round hole 901, which can restrict the position between the second balance pipe 3 and the first balance pipe 2, preventing the second balance pipe 3 and the first balance pipe 2 from separating. When disassembly is required for routine maintenance, pull the handle 15 again to raise the handle 15, which can remove the round rod 10 from the round hole 901, thereby releasing the restriction between the first balance pipe 2 and the second balance pipe 3, allowing the second balance pipe 3 to be removed from the first balance pipe 2, and the impurities remaining on the inner wall of the second balance pipe 3 to be rinsed or wiped to prevent the accumulation of impurities from affecting gas purity or clogging the pipe.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
