Description

Technical Field

[0001] The utility model relates to the technical field of waste gas detection, in particular to a multi-parameter detection instrument for waste gas emission. Background Art

[0002] Exhaust gas multi-parameter detection instrument, also often called multi-parameter gas detector or environmental monitoring instrument, is an instrument that can detect multiple gas parameters at the same time, including oxygen concentration, toxic gas concentration (such as carbon dioxide, ammonia, hydrogen sulfide, etc.), combustible gas concentration, temperature, humidity and other parameters. The instrument can detect the gas concentration in the exhaust gas in real time. When the measured gas reaches the preset alarm point, it will automatically sound and light alarm to remind the staff to take timely measures.

[0003] After searching, it was found that the Chinese patent with announcement number CN220854822U published a portable multi-parameter detection instrument for ambient air and exhaust gas. This patent can effectively avoid the detection errors that may be caused by the detection personnel accidentally touching the button when performing the task, ensuring the accuracy of the detection results and the stable operation of the detection instrument. However, in the actual application scenario, we found a detail that deserves optimization: when the detection head is placed in the exhaust gas environment for sampling, external physical effects (such as inadvertent pulling during operation) will cause the plug connecting the detection head and the interface of the detector to loosen or even fall off, which not only interrupts the continuity of the detection, but also has an adverse effect on the final detection effect, reducing the efficiency and reliability of the detection operation.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-7 A multi-parameter detection instrument for exhaust gas emission includes a box 1, a detector body 2 is placed inside the box 1, and the detector body 2 is an exhaust gas multi-parameter detection instrument, which is an instrument that can detect multiple gas parameters at the same time, and can detect multiple parameters such as oxygen concentration, toxic gas concentration (such as carbon dioxide, ammonia, hydrogen sulfide, etc.), combustible gas concentration, temperature, humidity, etc. The instrument can detect the gas concentration in the exhaust gas in real time. When the measured gas reaches the preset alarm point, it will automatically send out an audible and visual alarm to remind the staff to take timely measures.

[0031] The tail end of the detector body 2 is provided with a plurality of interfaces, and the upper and lower sides of the interfaces are respectively fixedly connected with a first locking component 3 and a second locking component 4, and the first locking component 3 and the second locking component 4 are arranged opposite to each other;

[0032] The first locking assembly 3 and the second locking assembly 4 both include a fixing plate 301 and a pressing plate 302, and the fixing plate 301 is fixedly connected to the rear end of the detector body 2;

[0033] A slide slot 303 is provided in the middle of the pressing plate 302, one end of the fixed plate 301 passes through the slide slot 303 and extends to the outside of the pressing plate 302, a thrust spring 304 is fixedly connected between the inner bottom wall of the slide slot 303 and the bottom of the fixed plate 301, and a pressing slot 305 is provided at the bottom of the pressing plate 302. Through the arrangement of the first locking assembly 3 and the second locking assembly 4, and the elastic force of the thrust spring 304, the connection between the interface of the detector body 2 and the plug of the external detection head 6 is more stable and reliable, effectively reducing the risk of loosening or falling off due to external force, and the stable connection ensures the continuity of the detection process, reducing the time required for reconnection or adjustment due to loose interfaces, thereby improving detection efficiency.

[0034] The interface has a plug movably inserted inside, a connecting wire 5 is fixedly connected to the plug, and one end of the connecting wire 5 is fixedly connected to a detection head 6 for exhaust gas multi-parameter detection. Different detection tasks require different types of detection heads 6 to adapt to different exhaust gas components and detection requirements. By separating the detection head 6 from the detector body 2 and connecting it to the interface of the detector body 2 through the connecting wire 5 and the plug, different types of detection heads 6 can be replaced according to actual needs, thereby improving the flexibility and adaptability of the instrument.

[0035] The first locking assembly 3 and the second locking assembly 4 are relatively clamped on the outer surface of the connecting line 5. This ensures that the connection between the plug and the interface of the detector body 2 will not loosen or fall off due to these external forces, thereby improving the stability and reliability of the detection instrument.

[0036] The inner wall of the slide groove 303 is provided with a guide groove, and guide blocks (not shown in the figure) are provided on both sides of the fixed plate 301. The guide blocks (not shown in the figure) are slidably connected inside the guide groove. The cooperation between the guide groove and the guide block ensures the linearity and stability of the pressing plate 302 during the up and down movement, and prevents the pressing plate 302 from deflecting or shaking during the movement.

[0037] The two sides of one end of the fixed plate 301 are fixedly connected with the limiting plate 306, and the inner side of the limiting plate 306 is slidably connected with the outer side of the pressing plate 302. The limiting plate 306 limits the pressing plate 302 to prevent the pressing plate 302 from sliding off the fixed plate 301.

[0038] The pressing groove 305 is in an arc shape, and an arc pad 307 is fixedly connected to the inner wall of the pressing groove 305, and the arc pad 307 is clamped on the outer surface of the connecting line 5. The inner diameter of the arc pad 307 is equal to the outer diameter of the connecting line 5. The arc pad 307 can fit tightly on the outer surface of the connecting line 5 to form a gapless connection, and this tight fit helps to reduce the gap at the connection and improve the tightness and stability of the connection.

[0039] Positioning rods 308 are fixedly connected to both sides of the bottom of the first locking component 3, and positioning holes are opened on both sides of the top of the second locking component 4. The positioning rods 308 are movably inserted into the positioning holes. The cooperation between the positioning rods 308 and the positioning holes ensures that the first locking component 3 and the second locking component 4 can be accurately aligned when connected, avoiding the problem of loose or unstable connection caused by position deviation, and improving the accuracy and reliability of the connection.

[0040] The box 1 is provided with an instrument placement cavity 7 and a harness placement cavity 8, respectively. The detector body 2 is placed in the instrument placement cavity 7, and the connecting wire 5 and the detection head 6 are placed inside the harness placement cavity 8. Placing the detector body 2, the connecting wire 5 and the detection head 6 in separate cavities respectively realizes the orderly management and classified storage of the equipment components, helps to reduce the clutter in the box 1, and improves the overall aesthetics and neatness.

[0041] A box cover 9 is hinged on the top of the box body 1, and a rubber pad 10 is fixedly connected to the bottom of the box cover 9; buckles 11 are fixedly connected to both sides of the front of the box body 1, and hooks 12 are fixedly connected to both sides of the front of the box cover 9, the buckles 11 are hung on the hooks 12, and a handle 13 is fixedly connected to the front of the box body 1.

[0042] Working principle: The upper and lower pressure plates 302 need to be gently pushed in opposite directions to increase the distance between the pressure plates 302. At the same time, the thrust spring 304 is compressed and in a state of storing force. At this time, the internal space of the interface at the tail end of the detector body 2 is fully exposed, making it easy to accurately insert the plug connected to the detection head 6 into the interface of the detector body 2.

[0043] After the plug is inserted, the push on the pressure plate 302 is released. At this time, the previously compressed thrust spring 304 quickly releases the stored energy, pushing the two pressure plates 302 to move together quickly in opposite directions along the guide of the slide groove 303 on the fixed plate 301, and the pressure groove 305 on the pressure plate 302 is fixed on the outer surface of the connecting line 5, realizing a stable connection between the plug and the interface.

[0044] Due to the continuous action of the thrust spring 304, the pressure plate 302 can maintain a tightly locked state on the connecting line 5, effectively resisting various external forces in the external environment, such as vibration, pulling, etc., thereby ensuring that the connection between the plug and the interface of the detector body 2 will not loosen or fall off due to these external forces. This not only improves the stability and reliability of the detection instrument, but also greatly simplifies the user's operating process and improves work efficiency.

[0045] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
