Description

Technical Field

[0001] This utility model relates to the field of gas monitoring and sampling, and in particular to a sampling device for liquefied gas analysis. Background Technology

[0002] In the production, transportation, and storage of liquefied gases, gas leaks not only waste resources but can also lead to serious safety accidents. Therefore, accurate leak monitoring and gas sampling are crucial. Existing liquefied gas sampling devices have several shortcomings. For example, the monitoring nozzles are fixed in position or inconvenient to adjust, making it difficult to accurately target leak points in complex environments, leading to data deviations. Some devices lack angle adjustment mechanisms or have cumbersome adjustment methods, affecting sampling efficiency. Furthermore, most devices lack efficient gas extraction capabilities, allowing residual leaked gas inside the sampler chamber to interfere with sample collection, preventing the sample from accurately reflecting the gas composition and introducing errors into subsequent analysis. Therefore, there is an urgent need for a sampling device that can flexibly adjust the monitoring position and angle and efficiently extract leaked gas to improve the accuracy and safety of liquefied gas sampling.

[0003] While existing technologies can achieve certain sampling effects, they suffer from drawbacks such as the lack of a monitoring tip angle adjustment method and an effective gas extraction function. In view of this, we propose a sampling device for liquefied gas analysis that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a sampling device for liquefied gas analysis.

[0005] The technical solution of this utility model is as follows: A sampling device for liquefied gas analysis includes a sampler housing and a monitor. The monitor is fixedly connected to one outer wall of the sampler housing. The monitor is provided with a monitoring pipe. A monitoring suction head is fixedly connected to one end of the monitoring pipe. A connecting rod is fixedly connected to one outer wall of the monitoring suction head. A handle is fixedly connected to one end of the connecting rod.

[0006] When using one of the liquefied gas analysis sampling devices in this solution, hold the handle and bring the monitoring tip close to the leaky area. Use the magnet on one end of the mounting bracket on the monitoring tip to make it adhere to the leaky area. Pull the connecting rod, at which point the limiting block will disengage from the limiting groove under the pulling force. Simultaneously rotate the monitoring tip and adjust it to a suitable angle according to the actual monitoring point location to get closer to the monitoring point. Release the connecting rod, and under the elastic action of the spring, the limiting block will return to its original position and fall into the limiting groove on one side of the mounting bracket, thereby fixing the rotation angle of the monitoring tip and ensuring stable monitoring. Turn on the monitor and view the monitoring data on the display screen. If the liquefied gas concentration is abnormal, the buzzer will sound an alarm. At the same time, start the air pump on one side of the monitor to extract the gas from the sampler housing through the monitoring pipeline.

[0007] Preferably, the monitoring pipeline is fixedly connected to the mounting bracket, one side of the outer wall of the mounting bracket is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the outer wall of the handle, and a limiting groove is provided on one side of the mounting bracket.

[0008] Preferably, the connecting rod is provided with a limiting block, which is disposed in a limiting groove.

[0009] Preferably, a magnet is fixedly connected to the outer wall of one end of the mounting bracket.

[0010] Preferably, the monitor is equipped with a display screen, and a buzzer is fixedly connected to the upper outer wall of the monitor.

[0011] Preferably, an air pump is fixedly connected to one side of the outer wall of the monitor.

[0012] Preferably, the sampler housing contains a sampling bottle, the sampler housing has a movable door, and a bracket is fixedly connected to the lower outer wall of the sampler housing.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This utility model allows operators to easily move the monitoring nozzle to the target leak location by holding the handle and utilizing the connection structure between the connecting rod and the handle. The operation is simple and flexible. Simultaneously, the unique hexagonal limiting block and limiting groove, in conjunction with a spring, form an angle adjustment mechanism. When the connecting rod is pulled, the limiting block disengages from the limiting groove, allowing the monitoring nozzle to rotate freely for angle adjustment. After release, the spring returns to its original position, and the limiting block precisely falls into the limiting groove to fix the angle. This effectively solves the problems of inconvenient movement and difficult angle adjustment of the monitoring nozzle in existing technologies, greatly improving the accuracy and efficiency of sampling.

[0015] Second, based on the first beneficial effect, once the concentration is abnormal, the monitor will control the buzzer to sound an alarm in a timely manner. After the alarm is triggered, the air pump will start quickly and rapidly extract the gas from the sampler box through the monitoring pipeline, thus preventing the leakage of gas from harming the staff.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-4 As shown, this embodiment is a sampling device for liquefied gas analysis, including a sampler housing 2 and a monitor 8. The monitor 8 is fixedly connected to the outer wall of one side of the sampler housing 2. The monitor 8 is provided with a monitoring pipe 5. A monitoring pipe 10 is fixedly connected to one end of the monitoring pipe 5. A connecting rod 15 is fixedly connected to the outer wall of one side of the monitoring pipe 10. A handle 14 is fixedly connected to one end of the connecting rod 15. In use, the sampler housing 2 is connected to the sampling bottle 1 through the pipe to sample liquefied gas. This is prior art and will not be described or illustrated in detail here. The monitoring pipe 10 is made of rubber material and has a certain deformation capability, providing a basis for adjusting its angle.

[0030] Example 2

[0031] Please see Figures 1-4 As shown, this embodiment, based on embodiment 1, further includes: a mounting bracket 11 for fixed connection of the monitoring pipe 5; one end of the spring 13 is fixedly connected to the outer wall of one side of the mounting bracket 11, and the other end of the spring 13 is fixedly connected to the outer wall of the handle 14; a limiting groove 16 is provided on one side of the mounting bracket 11. During use, when the operator pulls the handle 14 to move the connecting rod 15, the spring 13 is stretched, and the limiting block 17 disengages from the limiting groove 16, allowing for adjustment of the angle of the monitoring suction head 10; after releasing the handle 14, the spring 13 returns to its original position, pushing the limiting block 17 back into the limiting groove 16, thus fixing the angle of the monitoring suction head 10. The limiting groove 16 on one side of the mounting bracket 11 cooperates with the limiting block 17 on the connecting rod 15 to limit and fix the rotation angle of the monitoring suction head 10.

[0032] The connecting rod 15 is provided with a limiting block 17, which is located in the limiting groove 16. In use, both the limiting block 17 and the limiting groove 16 are hexagonal in design, so that the limiting block 17 can move along the axis of the connecting rod 15 after falling into the limiting groove 16 and cannot rotate.

[0033] A magnet 12 is fixedly connected to the outer wall of one end of the mounting bracket 11. During use, the monitoring nozzle 10 can be quickly and firmly attached to metal parts that are prone to leakage without the need for additional fixing operations, thus improving sampling efficiency. At the same time, this adsorption method makes the installation and removal of the monitoring nozzle 10 more convenient, allowing operators to quickly move it between different detection points.

[0034] The monitor 8 is equipped with a display screen 6, and a buzzer 9 is fixedly connected to the upper outer wall of the monitor 8. The display screen 6 on the monitor 8 can display monitoring data such as the concentration and pressure of liquefied gas in real time, so that the operator can intuitively understand the gas status in the current detection environment and provide a basis for judging whether there is a gas leak and the degree of the leak. When the buzzer 9 fixedly connected to the upper outer wall of the monitor 8 detects an abnormal concentration of liquefied gas that exceeds the preset safety threshold, it will sound an alarm to promptly remind the operator to take appropriate measures to avoid safety accidents caused by liquefied gas leakage and to ensure the personal safety of the operator and the safety of the working environment.

[0035] An air pump 7 is fixedly connected to one side of the outer wall of the monitor 8. When in use, the air pump 7 fixedly connected to one side of the outer wall of the monitor 8 will start after detecting a liquefied gas leak. It will extract the gas from the sampler box 2 through the monitoring pipe 5 to avoid the safety hazards caused by the leaked gas remaining in the box and to ensure the safety of the staff.

[0036] The sampler housing 2 contains a sampling bottle 1 and a movable door 4. A bracket 3 is fixedly connected to the lower outer wall of the sampler housing 2. During use, the movable door 4 allows operators to easily place or remove the sampling bottle 1 into the sampler housing 2. At the same time, the movable door 4 can be closed during sampling to maintain a relatively closed environment inside the sampler housing 2, reducing the impact of external factors on the sampling results. The bracket 3 fixedly connected to the lower outer wall of the sampler housing 2 provides stable support for the entire sampling device, ensuring that the device remains balanced during use and preventing shaking or tipping from affecting the normal operation of sampling and monitoring. It also facilitates the movement and placement of the device by operators in different work sites.

[0037] Instructions for use: Hold handle 14 and bring the monitoring nozzle 10 close to the leaky area. Use the magnet 12 on one end of the mounting bracket 11 on the monitoring nozzle 10 to make it adhere to the leaky area. Pull the connecting rod 15. At this time, the limiting block 17 will disengage from the limiting groove 16 under the pulling force. At the same time, rotate the monitoring nozzle 10. Adjust the monitoring nozzle 10 to a suitable angle according to the actual monitoring point position so as to get closer to the monitoring point. Release the connecting rod 15. Under the elastic action of the spring 13, the limiting block 17 will return to its original position and fall into the limiting groove 16 on one side of the mounting bracket 11, thereby fixing the rotation angle of the monitoring nozzle 10 and ensuring stable monitoring. Turn on the monitor 8 and view the monitoring data through the display screen 6. If the liquefied gas concentration is abnormal, the buzzer 9 will sound an alarm. At the same time, start the air pump 7 on one side of the monitor 8 to extract the gas from the sampler box 2 through the monitoring pipe 5.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
