Description

Technical Field

[0001] The utility model relates to the field of pipeline hydrogen transportation, and specifically relates to a piston booster device with a sampling structure. Background Technique

[0002] Hydrogen has the characteristic of being extremely flammable. Once leaked, it may cause fire or explosion. Therefore, sampling and detecting the pipeline hydrogen transportation process is a necessary measure to ensure safe production. Timely monitoring of the hydrogen concentration and composition helps prevent accidents.

[0003] Monitoring the pressure data of hydrogen transported in the pipeline is very crucial. By analyzing whether the data fluctuates greatly or whether there are abnormal peaks, etc., potential safety hazards such as pipeline leaks and valve problems can be discovered.

[0004] The temperature data of hydrogen transported in the pipeline also needs to be monitored regularly. Abnormal temperature fluctuations or too high or too low temperatures may mean there are problems inside the pipeline. At this time, the reasons need to be checked in time and corresponding measures need to be taken.

[0005] Monitoring the flow rate data of hydrogen transported in the pipeline can understand the hydrogen transportation situation. Abnormal flow rate fluctuations or flow rate values deviating from the expected range may imply problems such as pipeline leaks and blockages inside the pipeline.

[0006] Detecting the component data of hydrogen in the hydrogen transmission pipeline, including hydrogen concentration, oxygen concentration, etc., can discover possible problems such as mixed gases and leaks.

[0007] Monitoring the operation status data of relevant equipment for transporting hydrogen in the pipeline, such as the opening and closing status of valves and the operation of pumps, etc., can discover potential safety problems such as equipment failures and operation errors.

[0008] The alarm record data of hydrogen transported in the pipeline is also very important. By analyzing the alarm records, the problems existing in the pipeline system can be understood and processed and improved in time.

[0009] By monitoring, analyzing, and comparing the technical data of hydrogen transported in the pipeline, potential safety problems can be discovered in time, corresponding measures can be taken to avoid accidents, and the safe operation of the hydrogen transportation system can be guaranteed.

[0010] Developing a sampling and detection device based on pipeline hydrogen transportation is to ensure the safe and stable operation, controllable quality, environmental protection, compliance requirements, accident prevention, and provide data support for enterprise decision-making in the hydrogen transportation process. Such a device can improve the safety, reliability, and efficiency of enterprise production and operation. Content of the Utility Model

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0036] Please refer to Figures 1 to 3 , in the embodiments of the present utility model, a piston supercharging device with a sampling structure includes a pipeline 1. The center of the outer wall of the pipeline 1 is connected with a limiting pipe 2, and the inner cavity of the pipeline 1 is communicated with the inner cavity of the limiting pipe 2. A piston mechanism penetrating into the inner cavity of the limiting pipe 2 is arranged outside the limiting pipe 2. The piston mechanism includes a piston plate slidably connected to the inner cavity of the limiting pipe 2; an air groove 8 is arranged inside the piston plate, and the output end of the air groove 8 is connected with a one-way sampling mechanism; the one-way sampling mechanism is used to introduce the gas inside the pipeline 1 into a sampling bottle to achieve the purpose of detecting the air inside the pipeline 1; a end plate is formed at one end of the limiting pipe 2 far away from the pipeline 1, and a connection port 10 aligned with the one-way sampling mechanism is opened on the end plate.

[0037] In this embodiment: when the device is used to transport and pressurize hydrogen, first try to dock a sampling device (such as a sampling bottle with a hard nozzle and a sampling balloon) with the one-way sampling mechanism to sample the gas in the pipeline 1. After the sampled gas enters the sampling bottle, transfer the sampling bottle, and use a humidity detector to detect the humidity of the taken-out gas. After passing the detection, start the device for transportation. If it is found that the humidity of the gas in the pipeline 1 is relatively high after detection, corresponding drying treatment needs to be carried out first;

[0038] After the treatment is completed, start the motor connected to the piston mechanism. The motor drives the piston mechanism to reciprocate to achieve the supercharging and transportation of hydrogen.

[0039] Please pay special attention to Figure 1 and Figure 2 , the piston mechanism includes a piston column 3 connected to one end of the piston. The end of the piston column 3 far away from the piston penetrates outside the end plate of the limiting pipe 2. A roller is rotatably connected to the inner side of the end of the piston column 3 located outside the limiting pipe 2. The outer wall of the roller is movably connected with a turntable 4. An activity groove 5 for the roller to move is opened on the end surface of the turntable 4, and an eccentric column 6 is formed at the eccentric position of the turntable 4.

[0040] In this embodiment: The operation of the motor drives the eccentric column 6 to rotate, the eccentric column 6 drives the turntable 4 to rotate, the turntable 4 drives the movable groove 5 to rotate, the movable groove 5 pulls the roller to move axially during rotation, and the roller drives the piston column 3 to reciprocate. The reciprocating movement of the piston column 3 causes the piston to reciprocate, thereby achieving suction and thrust and completing the pressurized transportation of hydrogen.

[0041] Please refer specifically to Figure 2 and Figure 3 , the one-way sampling mechanism includes a connecting pipe 9 connected to the output end of the air tank 8. An activity plate 12 is movably connected to the inner wall of the connecting pipe 9. The center of the activity plate 12 is in an open structure. A hollow pipe 13 is integrally formed at one end of the activity plate 12. A blocking plate 14 is integrally formed at the end of the hollow pipe 13 away from the activity plate 12. The outer diameter of the blocking plate 14 is smaller than the inner diameter of the connecting pipe 9. The one-way sampling mechanism further includes a fixing plate 11 welded to the inner wall of the connecting pipe 9. The center of the fixing plate 11 is in an open state, and the inner diameter of the opening at the center of the fixing plate 11 is equal to the outer diameter of the hollow pipe 13; A plurality of first air holes 15 are circumferentially and equidistantly formed at the eccentric part of the fixing plate 11. The blocking plate 14 in the reset state is used to block the first air holes 15; A plurality of second air holes 16 are circumferentially formed on the hollow pipe 13, and the second air holes 16 communicate with the inner cavity of the hollow pipe 13; One end of the activity plate 12 and one end of the fixing plate 11 are connected by a spring 17.

[0042] In this embodiment: When the hard nozzle is inserted through the connection port 10 and contacts the activity plate 12 and pushes the activity plate 12 to move, the activity plate 12 drives the blocking plate 14 to move through the hollow pipe 13. During this process, the spring 17 is compressed. Due to the movement of the blocking plate 14, the blocking plate 14 no longer blocks the first air holes 15. The gas in the pipeline 1 enters the outer periphery of the hollow pipe 13 through the first air holes 15, and then enters the inner periphery of the hollow pipe 13 through the second air holes 16. Then, pinch the one-way airbag. During the process of pinching the one-way airbag, the gas is absorbed and enters the sampling bottle;

[0043] The gas sampling in the pipeline 1 is completed.

[0044] Please refer specifically to Figure 2 , two one-way valves 7 are installed on the inner wall of the pipeline 1. The upper one-way valve 7 is used for one-way air intake, and the lower one-way valve 7 is used for one-way air outlet.

[0045] In this embodiment: During the reciprocating movement of the piston, during the pushing process of the piston plate, the gas pressure acts on the lower one-way valve 7, and the lower one-way valve 7 is opened, and the gas is output. During the reset process of the piston plate, the generated suction acts on the upper one-way valve 7, and the upper one-way valve 7 is opened, and the gas enters between the two one-way valves 7.

[0046] Please refer to the figure with emphasis. The contact position between the piston column 3 and the end plate of the limit tube 2 is slidably connected through a linear bearing.

[0047] In this embodiment: The linear bearing can effectively reduce the friction between the piston column 3 and the short plate of the limit tube 2.

[0048] Please refer to with emphasis Figure 1 and Figure 2 , a sealing ring is provided at the contact position between the piston and the inner wall of the limit tube 2, and a sealing ring is provided at the contact position between the plugging plate 14 and the fixing plate 11.

[0049] In this embodiment: The sealing ring can effectively improve the sealing performance of the device and prevent air leakage.

[0050] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
