Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Combination Figures 1 to 5 As shown, a high-pressure gas sampling device provided by the utility model includes a storage tank 1 and an air inlet pipe 2.

[0032] Combination Figures 1 to 5 As shown, a partition 11 is provided inside the storage tank 1 to separate the internal space, and a through hole is provided on the top surface of the storage tank 1 and the partition 11; the air inlet pipe 2 is slidably assembled in the through hole on the top surface of the storage tank 1, and the outer wall of the air inlet pipe 2 and the inner wall of the through hole are sealed and fitted, and when the air inlet pipe 2 slides downward to pass through the through hole of the partition 11, the outer wall of the air inlet pipe 2 is sealed and fitted with the inner wall of the through hole of the partition 11; when the air outlet below the air inlet pipe 2 is located above the partition 11, the high-pressure gas passes through the internal space above and below the partition 11, and when the air outlet below the air inlet pipe 2 moves to below the partition 11, the internal space above the partition 11 is closed to store a sampling sample, and the high-pressure gas continues to enter the space below the partition 11.

[0033] In this embodiment, the storage tank 1 is separated into multiple internal spaces by a partition 11, and high-pressure gas is input into the storage tank 1 through a slidably assembled intake pipe 2. Since the partition 11 is provided with a through hole, the multiple internal spaces in the storage tank 1 are interconnected in the initial state. When the intake pipe 2 moves and passes through the through hole, the intake pipe 2 will close the space above the partition 11 to store a sample. At this time, the high-pressure gas continues to enter the space below the partition 11 to ensure the freshness of the sample taken at the next time point.

[0034] In this embodiment, all the through holes connecting the inner and outer spaces of the storage tank 1 are not considered as sealing structures, and the valves and other structures used in the prior art can meet the use requirements of the sealing structure. The above-mentioned through holes connecting the inner and outer spaces of the storage tank 1 include the vent hole 12, the air inlet above the air inlet pipe 2, etc.

[0035] In this embodiment, the number of the partitions 11 can be appropriately increased according to actual needs, and the length of the air intake pipe 2 can be increased simultaneously to meet the needs of a larger number of samples.

[0036] In addition, the high-pressure gas sampling device in this embodiment can also be used to increase the fault tolerance rate. For example, when the number of sampling samples required is 1, two internal spaces can be separated in the storage tank 1. When the operator replaces the high-pressure gas sampling device in time, the high-pressure gas sampling device only collects sampling samples within a time period. When the operator fails to replace it in time, the fault tolerance rate of a time period can be increased to avoid a series of problems caused by untimely operation.

[0037] In some embodiments, in combination Figure 1 , Figure 2 As shown, the air inlet pipe 2 is a cylindrical tube that penetrates from top to bottom, the sizes of the through holes on the top surface of the storage tank 1 and the through holes on the partition 11 are equal to the outer size of the air inlet pipe 2, and the bottom surface of the storage tank 1 is integrally formed with an air outlet, and the high-pressure gas enters the storage tank 1 through the air inlet pipe 2, and the high-pressure gas is discharged from the storage tank 1 through the air outlet. The structure of this embodiment is relatively simple, and the outer size of the air inlet pipe 2 can simultaneously meet the requirements of sealing and fitting multiple through holes on the partition 11, and multiple internal spaces in the storage tank 1 are closed in sequence during the movement of the air inlet pipe 2.

[0038] In some embodiments, in combination Figure 4 , Figure 5 As shown, it also includes a sealing component 3, which is a stepped telescopic rod. The sealing component 3 is assembled in the through hole on the top surface of the storage tank 1, and the intake pipe 2 is assembled in the sealing component 3 as the tip section of the sealing component 3. Each section of the sealing component 3 respectively closes the through holes on each partition 11. The interior of the sealing component 3 is hollow and connected to the interior of the intake pipe 2. The high-pressure gas enters the storage tank 1 through the sealing component 3 and the intake pipe 2.

[0039] In this embodiment, the design of the sealing component 3 can reduce the size requirements when sealing multiple internal spaces. Each step section of the sealing component 3 is responsible for sealing the internal space of a storage tank 1. The size of the through hole of the partition 11 is sealed to fit each step section of the sealing component 3. The through hole of the partition 11 can also be designed with a sinking groove to achieve sealing through the upper and lower contact surfaces, thereby further reducing the size requirements for sealing.

[0040] In some embodiments, in combination Figure 4 , Figure 5 As shown, the number of partitions 11 is the same as the number of step sections of the sealing component 3, the height of the partition 11 dividing the internal space is the same as the height of each step section of the sealing component 3, and the size of the through hole on the partition 11 is the same as the outer size of the corresponding step section. The limitation on the structural size of the sealing component 3 can ensure the normal working effect of the sealing component 3. The limitation on the number of step sections and the height of the step sections of the sealing component 3 in this embodiment is a requirement for the minimum size of the sealing component 3. The same technical effect may be achieved when the size of the sealing component 3 exceeds the limited size.

[0041] In some embodiments, in combination Figure 6 As shown, the air intake pipe 2 is a cylindrical tube, and a baffle is integrally formed inside the air intake pipe 2. Vent holes are provided on the side walls on both sides of the baffle. An assembly hole is provided on the bottom surface of the storage tank 1. The air intake pipe 2 is slidably assembled in the assembly hole. The high-pressure gas enters the storage tank 1 through the vent hole above the baffle, and then enters the air intake pipe 2 through the vent hole below the baffle and is discharged.

[0042] In this embodiment, the design of the intake pipe 2 is mainly aimed at the problem of driving the intake pipe 2 after adding the sealing component 3. At this time, the high-pressure gas enters the storage tank 1 through the vent hole above the baffle, and then discharges the storage tank 1 through the vent hole below the baffle. The intake pipe 2 runs through the bottom plate of the storage tank 1. The driving original can be fixed on the bottom plate of the storage tank 1 to connect the intake pipe 2 to solve the driving problem.

[0043] In some embodiments, in combination Figure 6 As shown, the vent holes on both sides of the baffle are opened in opposite directions, and the two vent holes are always located inside the storage tank 1. In this embodiment, since the two vent holes are close to each other, in order to allow the high-pressure gas to fully fill the storage tank 1, the vent holes on both sides are designed to have opposite opening directions, so that the high-pressure gas can be discharged only after circling the inside of the storage tank 1, thereby ensuring sufficient gas exchange.

[0044] In some embodiments, in combination Figure 1 , Figure 4As shown, the high-pressure gas sampling device also includes a driving device 4, which is fixedly connected to the storage tank 1, and the driving end of the driving device 4 is connected to the intake pipe 2 and drives the intake pipe 2 to slide. The function of the driving device 4 is to drive the intake pipe 2 to move, so that the intake pipe 2 moves to a designated position in a specific time period. The driving device 4 is preferably a linear motor that can directly drive the intake pipe 2 to move, and other power elements and transmission structures can also be used to drive the intake pipe 2 to move.

[0045] In some embodiments, the drive device 4 is electrically connected to an external control center, and the external control center records and electrically controls the movement state of the drive device 4, so as to control the sampling time node through the external control center. At the same time, the operator can directly understand the status information of the intake pipe 2 through the external control center, which is convenient for centralized and unified management and planning.

[0046] In some embodiments, in combination Figure 1 , Figure 2 and Figure 4 As shown, the storage tank 1 has an integrally formed side wall with ventilation holes 12, the number of the ventilation holes 12 is the same as the number of the internal space of the storage tank 1, and each of the side walls of the internal space of the storage tank 1 is individually provided with one ventilation hole 12, and the ventilation hole 12 is a channel for taking the sample out of the storage tank 1.

[0047] In some embodiments, in combination Figure 3 As shown, the outer wall of the air intake pipe 2 is provided with scale lines 21, the number of the scale lines is the same as the number of internal spaces of the storage tank 1, and the positions of the scale lines respectively correspond to the relative positions of the air intake pipe 2 when the internal space of each storage tank 1 is closed. The scale lines 21 are a design for mechanically displaying the position information of the air intake pipe 2. The mechanical display result has higher reliability and can ensure that the operator can grasp the working status of the sampling device or discover the problem in time when there is a problem with the electronic system.

[0048] Working process: In the initial state, the air intake pipe 2 is passed into the inner side of the storage tank 1, and the outlet of the air intake pipe 2 is located above the partition 11. At this time, the through hole of the partition 11 connects the internal space above and below the partition 11, and the high-pressure gas will flow through the internal space above and below the partition 11. The samples taken in the internal space above and below the partition 11 are the same.

[0049] The intake pipe 2 will move downward slowly and in a controllable manner. After a specified time, the intake pipe 2 passes through the partition 11, and the outlet of the intake pipe 2 is located below the partition 11. At this time, the internal space above the partition 11 is in a closed state and is not connected to the internal space below the partition 11. The high-pressure gas no longer flows through the internal space above the partition 11, and the sampling samples in the internal space above and below the partition 11 begin to be different.

[0050] When taking out samples, the sampled samples in the internal space above and below the partition 11 belong to different time nodes, and different sampled samples are taken out through their respective vents 12. Finally, the air inlet pipe 2 needs to be restored to its original position.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
