Description

Technical Field

[0001] This utility model relates to the field of instrumentation and measurement technology, and in particular to the structure of a portable H2S gas detector. Background Technology

[0002] Hydrogen sulfide (H2S), a toxic and harmful gas, is widely present in industries such as petrochemicals, wastewater treatment, and mining, posing a serious threat to the lives of workers. Portable H2S gas detectors, due to their flexibility and real-time monitoring capabilities, have become indispensable safety equipment in field operations. With the increasing complexity of industrial environments, higher demands are placed on the structural design of detectors, requiring not only ensuring detection accuracy and response speed, but also considering portability, ease of maintenance, and environmental adaptability.

[0003] Currently, portable H2S gas detectors on the market typically employ either an integrated or separate design. An integrated design securely connects the measuring and display units, offering strong overall integrity but making maintenance difficult. While a separate design facilitates the replacement of some components, the connection methods often employ threaded fasteners or plug-in designs, making disassembly and assembly cumbersome and prone to wear and tear from frequent operation. Furthermore, existing devices often use simple dust covers or rubber plugs for interface protection, offering limited protection, especially in harsh environments where vibration or impact can easily damage or contaminate the interfaces.

[0004] However, existing split-type testing instruments have significant shortcomings in the connection method between the measurement unit and the display unit. The disassembly and assembly process usually requires tools or multiple steps, which is not only inefficient but also makes it difficult to quickly replace or maintain components in emergency situations. In addition, repeated disassembly and assembly can easily lead to loosening of the connection structure, affecting the stability and reliability of the equipment. This problem is particularly prominent in work scenarios that require frequent maintenance or adjustments. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable H2S gas detector structure, which aims to improve the problem that the existing split detectors usually require tools or multiple steps to disassemble and assemble the measurement unit and the display unit, which is not only inefficient, but also makes it difficult to quickly replace or maintain parts in emergency situations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable H2S gas detector structure, including a measuring cell, a connecting pipe one fixedly connected to the outer wall of the measuring cell, a connecting pipe two attached to the outer wall of the connecting pipe one, a data display instrument fixedly connected to one end of the connecting pipe two, a sampling pipeline fixedly connected to the outer wall of the data display instrument, a connecting plate one fixedly connected to the outer wall of the connecting pipe one, a connecting plate two fixedly connected to the outer wall of the connecting pipe two, a protrusion fixedly connected to the outer wall of the connecting plate one, and a disassembly assembly provided inside the protrusion;

[0008] Furthermore, a fixed column is fixedly connected to the outer wall of the measuring pool, a rotating plate is rotatably connected to the outer wall of the fixed column, a fixed plate is fixedly connected to the outer wall of the rotating plate, a fixed sleeve is fixedly connected to the outer wall of the fixed plate, a receiving end data interface is fixedly connected to one side of the outer wall of the measuring pool, a transmitting end data interface is fixedly connected to the other side of the outer wall of the measuring pool, and a protective component is provided on the inner wall of the fixed sleeve.

[0009] Furthermore, the protective component includes a protective sleeve, the outer wall of which is slidably connected to the inner wall of the fixed sleeve, a slider fixedly connected to the outer wall of the protective sleeve, a threaded rod fixedly connected to the outer wall of the protective sleeve, and a knob fixedly connected to one end of the threaded rod.

[0010] Furthermore, a data display instrument is provided outside the measuring pool, and the handle is located above the connecting plate two.

[0011] Furthermore, one end of the spring is fixedly connected to the outer wall of the sliding plate, and the other end of the spring is fixedly connected to the inner wall of the connecting plate.

[0012] Furthermore, the outer wall of the sliding plate is slidably connected to the inner wall of the second connecting plate, the outer wall of the locking block is slidably connected to the inner wall of the second connecting plate, and the outer wall of the pull rod is slidably connected to the inner wall of the second connecting plate.

[0013] Furthermore, the inner wall of the protective sleeve is fitted to the outer wall of the receiving end data interface, and the outer wall of the slider is slidably connected to the inner wall of the fixed sleeve.

[0014] Furthermore, the outer wall of the threaded rod is threadedly connected to the inside of the rotating plate, and the knob is located on the outer wall of the rotating plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the efficient separation and assembly of the measuring cell and the data display instrument are realized.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 This utility model provides an embodiment of a portable H2S gas detector structure, including a measuring cell 1 as the core detection component for accurately detecting the concentration of H2S gas in the environment. A connecting pipe 6 is fixedly connected to the outer wall of the measuring cell 1, serving as part of the main connection channel. A connecting pipe 7 is attached to the outer wall of the connecting pipe 6, and is fixedly connected to a data display instrument 2, which cooperates with the connecting pipe 6 to achieve quick connection. One end of the connecting pipe 7 is fixedly connected to the data display instrument 2, which displays the H2S gas concentration detected by the measuring cell 1 in real time. The outer wall of the data display instrument 2 is fixedly connected to a sampling pipeline 5, which is connected to the data display instrument 2 and used to transmit gas sample or signal data. The outer wall of the connecting pipe 1 6 is fixedly connected to a connecting plate 16, which is fixed on the connecting pipe 1 6 and provides the mounting base for the locking structure. The outer wall of the connecting pipe 2 7 is fixedly connected to a connecting plate 2 17, which is fixed on the connecting pipe 2 7 and accommodates the movement mechanism of the disassembly and assembly components. The outer wall of the connecting plate 1 16 is fixedly connected to a protrusion 23, which is fixed on the connecting plate 1 16 and forms a locking structure with the locking block 22. The disassembly and assembly components are provided inside the protrusion 23.

[0027] The disassembly and assembly assembly includes a locking block 22, which cooperates with a protrusion 23 to lock and release the connection mechanism. The outer wall of the locking block 22 is slidably connected to the inner wall of the protrusion 23. A sliding plate 21 is fixedly connected to the outer wall of the locking block 22, connecting the pull rod 20 and the locking block 22 to transmit force. A pull rod 20 is fixedly connected to the outer wall of the sliding plate 21 to transmit the pulling force of the handle 18 and drive the sliding plate 21 to move. A spring 19 is sleeved on the outer wall of the pull rod 20 to provide a reset elastic force to ensure that the locking block 22 automatically returns to its original position. A handle 18 is fixedly connected to one end of the pull rod 20 to provide a force point for the operator to apply force and control the movement of the disassembly and assembly assembly.

[0028] Specifically, when it is necessary to quickly disassemble the measuring cell 1 and the data display instrument 2 in the portable H2S gas detector, the operator first holds the handle 18 and pulls it outward, causing the pull rod 20 and the sliding plate 21 fixedly connected to it to slide smoothly in the inner wall of the connecting plate 17. At the same time, the spring 19 located between the sliding plate 21 and the connecting plate 17 is compressed. As the sliding plate 21 moves, the locking block 22 fixed on it completely exits from the protrusion 23 of the connecting plate 16, thereby releasing the locking state between the connecting plate 16 and the connecting plate 17. At this time, the connecting tube 7 can be easily separated from the connecting tube 6, realizing the quick disassembly of the measuring cell 1 and the data display instrument 2. When the handle 18 is released, the compressed spring 19 releases its elasticity, pushing the sliding plate 21 to reset, so that the locking block 22 re-enters the locking position, preparing for the next assembly. During this process, the sampling line 5 fixed on the data display instrument 2 is moved out together with the main body to ensure the neat and orderly connection line.

[0029] Reference Figures 1-5 A fixed column 8 is fixedly connected to the outer wall of the measuring pool 1, serving as the rotation axis of the rotating plate 9 and providing stable rotational support. The rotating plate 9 is rotatably connected to the outer wall of the fixed column 8, allowing it to rotate around the fixed column 8 to adjust the position of the fixed sleeve 11. A fixed plate 10 is fixedly connected to the outer wall of the rotating plate 9, providing rigid support for the fixed sleeve 11 and enhancing structural stability. The fixed sleeve 11 is fixedly connected to the outer wall of the fixed plate 10, accommodating the protective sleeve 12 and providing an installation base for the interface protection mechanism. A receiving data interface 3 is fixedly connected to one side of the outer wall of the measuring pool 1 for receiving data signals transmitted from external devices. A transmitting data interface 4 is fixedly connected to the other side of the outer wall of the measuring pool 1 for sending detection data signals to external devices. A protective component is provided on the inner wall of the fixed sleeve 11, including the protective sleeve 12, which slides over the data interface, providing dust and impact protection. The outer wall of the protective sleeve 12 is slidably connected to the inner wall of the fixed sleeve 11, and a slider 13 is fixedly connected to the outer wall of the protective sleeve 12. The protective sleeve 12 slides smoothly within the fixed sleeve 11 to ensure motion accuracy. A threaded rod 14 is fixedly connected to the outer wall of the protective sleeve 12, which converts rotational motion into linear motion to drive the protective sleeve 12 to move. A knob 15 is fixedly connected to one end of the threaded rod 14, providing an operating interface for easy manual control of the rotation of the threaded rod 14. A data display instrument 2 is installed outside the measuring pool 1. A handle 18 is located above the connecting plate 2 17. One end of the spring 19 is fixedly connected to the outer wall of the sliding plate 21, and the other end of the spring 19 is fixedly connected to the inner wall of the connecting plate 2 17. The outer wall of the sliding plate 21 is slidably connected to the inner wall of the connecting plate 2 17. The outer wall of the locking block 22 is slidably connected to the inner wall of the connecting plate 2 17. The outer wall of the pull rod 20 is slidably connected to the inner wall of the connecting plate 2 17. The inner wall of the protective sleeve 12 is attached to the outer wall of the receiving end data interface 3. The outer wall of the slider 13 is slidably connected to the inner wall of the fixed sleeve 11. The outer wall of the threaded rod 14 is threadedly connected to the inside of the rotating plate 9. The knob 15 is located on the outer wall of the rotating plate 9.

[0030] Specifically, when the detector needs to be stored, the operator can manually rotate the rotating plate 9 to make it rotate around the fixed column 8, accurately aligning the fixed sleeve 11 with the position of the receiving end data interface 3 or the transmitting end data interface 4. By rotating the knob 15 installed at the end of the threaded rod 14, the threaded rod 14 is rotated and the protective sleeve 12 is pushed to slide smoothly in the inner wall of the fixed sleeve 11. During this process, the slider 13 fixed to the outer wall of the protective sleeve 12 moves in the groove on the inner wall of the fixed sleeve 11, ensuring that the movement trajectory of the protective sleeve 12 is stable. When the protective sleeve 12 completely covers the receiving end data interface 3 or the transmitting end data interface 4, the rigid support structure formed by the fixed plate 10 and the fixed sleeve 11 provides reliable protection for the interface, which can effectively prevent dust from entering and physical collision damage, and keep the overall structure compact, significantly improving the portability and long-term reliability of the equipment.

[0031] Working principle: When the portable H2S gas detector needs to be used, and the measuring cell 1 and the data display instrument 2 need to be quickly disassembled, the operator pulls the handle 18 outward, causing the pull rod 20 and the sliding plate 21 to slide on the inner wall of the connecting plate 17. At the same time, the spring 19 is compressed. The movement of the sliding plate 21 causes the locking block 22 to exit from the protrusion 23, releasing the locking and fixing between the connecting plate 16 and the connecting plate 17. At this time, the connecting tube 7 can be easily separated from the connecting tube 6, realizing the quick disassembly of the measuring cell 1 and the data display instrument 2. The restoring force of the spring 19 ensures that the locking block 22 automatically returns to its position after the handle 18 is released, which is convenient for the next assembly. The sampling line 5 is moved out together with the data display instrument 2, completing the overall separation.

[0032] Furthermore, when the measuring pool 1 and the data display instrument 2 need to be stored, the rotating plate 9 can rotate around the fixed column 8, so that the fixed sleeve 11 is aligned with the receiving end data interface 3 or the transmitting end data interface 4. By rotating the knob 15, the threaded rod 14 is driven to move the protective sleeve 12 to slide on the inner wall of the fixed sleeve 11 until the protective sleeve 12 completely covers the receiving end data interface 3 or the transmitting end data interface 4. The slider 13 ensures its movement stability. The fixed plate 10 and the fixed sleeve 11 provide support to prevent damage to the interface. This saves space and effectively prevents dust and impact, improving portability and durability.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
