Description

Technical Field

[0001] This utility model relates to the field of sulfide standard gas technology, specifically a sulfide standard gas stability monitoring and control device. Background Technology

[0002] Sulfide standard gases are precisely formulated gas mixtures containing known and accurate concentrations of sulfides. They are typically stored in high-pressure gaseous form in specially designed steel cylinders or containers, serving as metrological standards, analytical method validation bases, or instrument calibration references. Their core function is to provide traceable concentration benchmarks for environmental monitoring, industrial process control, scientific research, and other fields, ensuring the accuracy and consistency of test results.

[0003] In existing technologies, sulfide standard gases are generally stored in bottles or tanks. When stored in tanks, electrochemical sensors are usually added to the tanks. By adding electrochemical sensors to the tanks storing sulfide standard gases, changes in gas concentration inside the tanks can be monitored in real time to provide early warning of leaks.

[0004] However, when the storage location of the tank is affected by the environment, the high humidity water vapor accelerates the dissolution and ionization of sulfides, leading to an increase in gas concentration. This increase may exceed the monitoring standard of the electrochemical sensor. Consequently, the excessively high concentration causes sulfides to rapidly form sulfide precipitates or highly corrosive intermediate products on the electrode surface, exacerbating the corrosion of the electrochemical sensor electrode material and ultimately leading to a decrease in sensor sensitivity. To address this, we propose a sulfide standard gas stability monitoring and control device. Utility Model Content

One end of the inner plate 15 is rotatably connected. An electrochemical sensor 14 is located at the center of the inner plate 13. The center of the inner plate 13 is connected to the outer side of the electrochemical sensor 14. A groove 111 is formed on one side of the inner surface of the empty tube 12. A rope 16 is provided on one side of the closing plate 15. One side of the closing plate 15 is fixedly connected to the top of the rope 16. The outer side of the rope 16 is slidably connected to the inner wall of the empty tube 12. A support plate 17 is provided at the bottom end of the rope 16. The bottom end of the rope 16 is fixedly connected to one side of the support plate 17. The top of the support plate 17 is... A telescopic rod 18 is provided, with the top of the support plate 17 fixedly connected to the bottom of one end of the telescopic rod 18. One end of the telescopic rod 18 is fixedly connected to the bottom of one end of the electrochemical sensor 14. A docking seat 114 is provided at the connection end of the electrochemical sensor 14, and the connection end of the electrochemical sensor 14 is inserted into the inner wall of the docking seat 114. One end of the docking seat 114 is fixedly connected to one side of the battery 112. An inverter 113 is provided on one side of the battery 112, and one side of the battery 112 and one side of the inverter 113 are connected by a wire. One end of the transformer 113 is fixedly connected to the docking seat 114 via a wire. The bottom end of the battery 112 is fixedly connected to the top side of the telescopic rod 18. The outer side of the telescopic rod 18 is fixedly connected to the inner wall of the empty tube 12. An elastic rope 19 is provided on one side of the closing plate 15. The top end of the elastic rope 19 is fixedly connected to one side of the closing plate 15. The bottom end of the elastic rope 19 is fixedly connected to one end of the inner wall of the inner plate 13. A retainer 110 is provided on the inner wall of the inner plate 13. The inner wall of the inner plate 13 is fixedly connected to one side of the retainer 110. The arc surface of the retainer 110 slides in contact with one side of the elastic rope 19 and the rope body 16, respectively.

[0027] When using this type of sulfide standard gas stability monitoring and control device, firstly, an empty tube 12 is installed on one side of the gas tank 11. The empty tube 12 is fixed to one side of the gas tank 11 by welding. An inner plate 13 is designed on the inner surface of one end of the empty tube 12. An electrochemical sensor 14 is slidably connected at the center of the inner plate 13. The diameter at the center of the inner plate 13 matches the diameter of the electrochemical sensor 14. Then, the sulfide standard gas inside the gas tank 11 is monitored in real time through the electrochemical sensor 14.

[0028] When the environment where the gas tank 11 is stored is affected by high humidity, water vapor will accelerate the dissolution and ionization of sulfides, and increase the corrosiveness to objects. Therefore, when the gas exceeds the monitoring standard of the electrochemical sensor 14, a telescopic rod 18 is designed on the bottom side of one end of the electrochemical sensor 14. A support plate 17 is installed on the bottom side of one end of the telescopic rod 18. A rope 16 is designed on the bottom side of the support plate 17. The rope 16 is connected to the support plate 17 through the inner plate 13. The other end of the rope 16 is located in the inner plate 13 and connected to one side of the closing plate 15. Furthermore, when the telescopic rod 18 retracts, it not only drives the electrochemical sensor 14 to retract from the center of the inner disk 13, but also drives the rope 16 to slide in the inner disk 13, gradually bringing the rope 16 out of the inner disk 13. During this process, the closing plate 15 will rotate 180 degrees due to the influence of external force. After the rotation, it will be located at the center of the inner disk 13, sealing the center position, thereby preventing the electrochemical sensor 14 from being corroded by gases exceeding the standard, and realizing the self-protection of the device and sensor protection in a high humidity environment.

[0029] Since the closing plate 15 has two sides, one side is connected to the rope 16 and the other side is connected to the elastic rope 19. The other end of the elastic rope 19 is fixed to one end of the inner wall of the inner plate 13. When the closing plate 15 rotates, the elastic rope 19 will stretch elastically. When the telescopic rod 18 extends, the closing plate 15 is not affected by the external force of the rope 16, and the elastic rope 19 will retract, resetting the closing plate 15. At the same time, the electrochemical sensor 14 re-enters the center of the inner plate 13, so that the closing plate 15 and the electrochemical sensor 14 form a linkage opening and closing structure, realizing the automatic switching between sensor monitoring and protection states. This ensures the smooth flow of gas during normal monitoring and can quickly restore the monitoring position through the reset mechanism of the elastic rope 19 when the gas exceeds the standard, ensuring that the device has the ability of cyclic protection and continuous monitoring.

[0030] A battery 112 is installed on the top side of the telescopic rod 18. One side of the battery 112 is connected to the inverter 113 via a wire, and one end of the inverter 113 is connected to the docking seat 114 via a wire. The docking seat 114 is plugged into the metal rod on the electrochemical sensor 14. The battery 112 supplies power to the electrochemical sensor 14, ensuring that the sensor does not interrupt data monitoring during the retraction protection process. At the same time, the inverter 113 realizes the matching conversion between the DC power of the battery 112 and the working voltage of the sensor, ensuring the stability and safety of the power supply.

[0031] Finally, the electrochemical hydrogen sulfide sensor used in this device, model GDD4H2S-100, was developed and manufactured by Hunan Xingshuo Sensor Technology Co., Ltd. It is an electrochemical hydrogen sulfide sensor with advantages such as high accuracy, low power consumption, high sensitivity, fast response speed, and strong anti-interference ability, and is suitable for monitoring sulfide standard gases.

[0032] Example 2: Please refer to Figure 2 - Figure 6 The support mechanism 2 includes an L-bar 21, a crossbar 22 is provided on one side of the L-bar 21, one side of the L-bar 21 is fixedly connected to one end of the crossbar 22, and the other end of the crossbar 22 is slidably connected to the inner surface of the slide groove 111. A battery 112 is provided on the inner side of the L-bar 21, and the inner side of the L-bar 21 is fixedly connected to one side of the bottom end of the battery 112.

[0033] A groove 111 is provided inside the empty tube 12. A crossbar 22 is connected to the inner surface of the groove 111. The other end of the crossbar 22 is fixedly connected to one side of the top of the L-rod 21, and the inner side of the L-rod 21 is fixedly connected to the outer side of the bottom end of the battery 112. In this way, when the battery 112 is in normal use or moved, the L-rod 21 and the crossbar 22 can make the battery 112 move stably and linearly along the direction of the groove 111. This ensures that the battery 112 moves synchronously with the electrochemical sensor 14 during the extension and retraction of the telescopic rod 18, and the limiting structure of the crossbar 22 and the groove 111 prevents the battery 112 from shaking radially. This ensures that the wire connection between the battery 112 and the inverter 113 remains stable and avoids power interruption due to poor contact.

[0034] Please see Figure 1 - Figure 6 An empty tube 12 is installed on one side of the gas tank 11. An electrochemical sensor 14 passes through the inner disk 13 via the empty tube 12 to monitor the gas inside the gas tank 11. When the gas exceeds the monitoring standard of the electrochemical sensor 14, a telescopic rod 18 is designed on the bottom side of one end of the electrochemical sensor 14. A support plate 17 is installed on the bottom side of one end of the telescopic rod 18. A rope 16 is designed on the bottom side of the support plate 17. The rope 16 passes through the inner disk 13 and is connected to the support plate 17. The other end of the rope 16 is located in the inner disk 13 and is connected to one side of the closing plate 15. Therefore, when the telescopic rod 18 retracts, it not only drives the electrochemical sensor 14 to retract from the center of the inner disk 13, but also drives the rope 16 to retract. 16 slides in the inner plate 13, gradually bringing the rope 16 out of the inner plate 13. During this process, the closing plate 15 will rotate 180 degrees due to the influence of external force. After the rotation, it will be located at the center of the inner plate 13, sealing the center position and thus preventing the electrochemical sensor 14 from being corroded by gases exceeding the standard. Secondly, when the telescopic rod 18 extends, the closing plate 15 is not affected by the external force of the rope 16, and the elastic rope 19 will retract, resetting the closing plate 15. At the same time, the electrochemical sensor 14 re-enters the center of the inner plate 13, so that the closing plate 15 and the electrochemical sensor 14 form a linkage opening and closing structure, realizing the automatic switching between sensor monitoring and protection states.

[0035] The crossbar 22 slides in the groove 111, and with the cooperation of the L-bar 21, the battery 112 can achieve stable linear movement along the direction of the groove 111. This ensures that the battery 112 moves synchronously with the electrochemical sensor 14 during the extension and retraction of the telescopic rod 18, and also prevents the battery 112 from wobbling radially through the limiting structure of the crossbar 22 and the groove 111.
