Description

Technical Field

[0001] This utility model is a VOCs rapid detection system based on mobile monitoring mode, belonging to the field of mechanical equipment. Background Technology

[0002] Rapid VOCs (volatile organic compounds) detection based on mobile monitoring involves using a portable detection device mounted on a mobile platform to achieve real-time monitoring of VOCs concentration, composition, and spatial distribution within a specific area. As a commonly used instrument for detecting volatile organic compounds, rapid VOCs analyzers often need to be mounted on mobile platforms such as automobiles and drones for mobile monitoring. This necessitates a pre-designed fixing structure on the outer casing for inserting bolts, ensuring a stable connection between the instrument and the mobile platform and preventing displacement or damage due to bumps or vibrations during movement.

[0003] In terms of casing material, plastic and metal are currently the two most widely used choices: plastic casings are suitable for most portable analyzers due to their lightweight and easy molding characteristics, while metal casings, due to their high strength and strong anti-interference capabilities, are mostly used in industrial-grade equipment with higher requirements for structural stability. Considering production efficiency and cost, the casings of VOCs rapid analyzers are usually mass-produced using injection molding. Molten plastic raw materials are injected into a mold to form the main structure and detailed features of the casing in one step. Integrating a fixing structure for inserting bolts into the casing would significantly increase the design complexity of the injection mold: such fixing structures often require corresponding protrusions, grooves, or core-pulling mechanisms within the mold, which would increase the processing difficulty and manufacturing cost of the mold. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a VOCs rapid detection system based on mobile mode to solve the problems mentioned in the background technology. This utility model reduces the production difficulty and manufacturing cost of the housing of the VOCs rapid analyzer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a VOCs rapid detection system based on mobile monitoring mode, comprising:

[0006] The VOCs rapid analyzer has an inlet pipe installed on the upper part of its outer surface, and an alarm is installed at one end of the inlet pipe.

[0007] A connector is located on the back of the VOCs rapid analyzer, and the connector is connected to the inlet pipe via a connector.

[0008] The positioning seat has a "T" shaped structure. The positioning seat is connected to the connecting seat by two screws. Fixing holes are provided at both ends of the positioning seat that do not contact the connecting seat.

[0009] Furthermore, the connector includes a connecting rod, and connecting rods are installed at both ends of the connecting seat. A semi-circular first clamp for fitting onto the inlet pipe is installed at the end of the connecting rod away from the connecting seat. A semi-circular second clamp for fitting onto the inlet pipe is provided on the side of the first clamp away from the connecting rod. The two ends of the first clamp are respectively connected to the two ends of the second clamp by bolts.

[0010] Furthermore, both ends of the first clamp are equipped with a first lug with holes, and both ends of the second clamp are equipped with a second lug with holes, and the first lug is connected to the second lug by bolts.

[0011] Furthermore, the connecting seat has a "U" shaped structure, and a plug is inserted into the space formed by the connecting seat and the VOCs rapid analyzer. One side of the plug has two screw holes, and one end of the screw passes through the positioning seat and the connecting seat and is threaded into the screw hole.

[0012] Furthermore, the connecting seat has two first small holes on the side facing the positioning seat, and the positioning seat has two second small holes aligned with the first small holes on the part that fits into the connecting seat. One end of the screw passes through the channel formed by the first and second small holes and is threaded into the screw hole.

[0013] Furthermore, the connecting seat has a first rectangular opening on the side facing the positioning seat, and the first rectangular opening is located between two first small holes.

[0014] Furthermore, a first elongated oval opening is provided on one side of the positioning seat, which is located between two fixing holes. A second elongated oval opening is provided on one side of the positioning seat, which is located between two second small holes.

[0015] Furthermore, a second rectangular opening is provided on one side of the insert block, and the second rectangular opening is located between two screw holes.

[0016] The beneficial effects of this utility model are:

[0017] 1. The fixed structure is formed by independent components such as the connecting seat and the positioning seat, eliminating the need to directly machine bolt holes and other fasteners onto the housing of the VOCs rapid analyzer. This design avoids the increased mold complexity caused by integrating complex fixed structures during housing injection molding, reducing the production difficulty and manufacturing cost of the housing. It also reduces injection molding defects caused by complex mold design. The ring-shaped structure formed by the first and second clamps is installed at the end of the inlet pipe using bolts, completing the assembly of the connecting seat and the VOCs rapid analyzer without requiring any changes to the original shape of the VOCs rapid analyzer.

[0018] 2. Insert the insert block with the machined screw hole into the space formed by the connecting seat and the VOCs rapid analyzer. Then, screw the screw through the positioning seat and the connecting seat and screw it into the screw hole. This eliminates the need to machine the screw hole on the connecting seat. If the thread in the screw hole is damaged due to stripping or other reasons, only the insert block needs to be replaced. There is no need to replace the structure formed by the first clamp, connecting rod and connecting seat, which reduces the cost of replacing parts. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] Please see Figure 1 and Figure 2This utility model provides a technical solution: a VOCs rapid detection system based on mobile mode, including a VOCs rapid analyzer 1. An inlet pipe 11 is installed on the upper part of the outer surface of the VOCs rapid analyzer 1, and an alarm 12 is installed at one end of the inlet pipe 11. The VOCs rapid analyzer 1 is a GC-PID detector. The GC-PID detector is a detection system that combines gas chromatography and photoionization detection. It has the component separation capability of gas chromatography and the high sensitivity of photoionization detection. It is widely used in the qualitative and quantitative analysis of volatile organic compounds. Its working principle has been fully disclosed in the prior art, so it will not be described in detail here.

[0032] See Figures 1-4 The connecting seat 4 is located on the back of the VOCs rapid analyzer 1. The positioning seat 2 has a "T" shaped structure and is connected to the connecting seat 4 by two screws 3. The two ends of the positioning seat 2 that do not contact the connecting seat 4 are provided with fixing holes 21. The two ends of the connecting seat 4 are equipped with connecting rods 41. The end of the connecting rod 41 away from the connecting seat 4 is equipped with a semi-circular first clamp 42 for fitting onto the inlet pipe 11. The side of the first clamp 42 away from the connecting rod 41 is provided with a semi-circular second clamp 43 for fitting onto the inlet pipe 11. The two ends of the first clamp 42 are equipped with a first ear with holes, and the two ends of the second clamp 43 are equipped with a second ear with holes. The first ear is connected to the second ear by bolts, thus completing the connection between the two ends of the first clamp 42 and the two ends of the second clamp 43. The fixing structure is constructed by independent components such as the connecting seat 4 and the positioning seat 2, eliminating the need to directly machine bolt holes and other fixing components on the outer shell of the VOCs rapid analyzer 1. This design cleverly avoids the problem of increasing mold complexity due to the integration of complex fixed structures during the injection molding production of the outer shell. It not only reduces the production difficulty and manufacturing cost of the outer shell, but also reduces injection molding defects (such as bubbles, deformation, etc.) caused by cumbersome mold design.

[0033] During assembly, bolts are used to close the first clamp 42 and the second clamp 43 to form a ring structure, which is then firmly fitted onto the end of the inlet pipe 11, thus completing the stable connection between the connector 4 and the VOCs rapid analyzer 1. The entire assembly process requires no modification to the original appearance of the VOCs rapid analyzer 1, perfectly preserving the instrument's original structure and performance, while achieving reliable fixation with the mobile platform, thus balancing production convenience and equipment compatibility.

[0034] See Figures 1-4The connecting seat 4 has a "U" shaped structure. A plug 5 is inserted into the space formed by the connecting seat 4 and the VOCs rapid analyzer 1. One side of the plug 5 has two screw holes 52. The side of the connecting seat 4 facing the positioning seat 2 has two first small holes 44. The part of the positioning seat 2 that fits with the connecting seat 4 has two second small holes 24 that are aligned with the first small holes 44. One end of the screw 3 passes through the channel formed by the first small holes 44 and the second small holes 24 and is threaded into the screw hole 52. The plug 5 with the pre-machined screw hole 52 is inserted into the gap between the connecting seat 4 and the VOCs rapid analyzer 1. Then the screw 3 is passed through the reserved holes of the positioning seat 2 and the connecting seat 4 in sequence and finally tightened into the screw hole 52 of the plug 5. This design eliminates the need for additional machining of the screw hole 52 in the connecting seat 4 itself, effectively simplifying the structural machining of the connecting seat 4.

[0035] When the threads in the screw hole 52 of the insert 5 become stripped or worn due to long-term use, the fixing function can be restored simply by disassembling and replacing the insert 5 alone, without replacing the entire structure consisting of the first clamp 42, connecting rod 41, and connecting seat 4. This modular component design significantly reduces the cost of replacing parts due to thread damage, while also reducing the amount of disassembly and assembly work required for maintenance.

[0036] See Figure 1 , Figure 3 and Figure 4 The connecting seat 4 has a first rectangular opening 45 on the side facing the positioning seat 2, which is located between two first small holes 44. The positioning seat 2 has a first elongated oval opening 22 on one side, which is located between two fixing holes 21. The positioning seat 2 has a second elongated oval opening 23 on one side, which is located between two second small holes 24. The insert block 5 has a second rectangular opening 51 on one side, which is located between two screw holes 52. The design of the first rectangular opening 45, the second rectangular opening 51, the first elongated oval opening 22, and the second elongated oval opening 23 reduces the amount of material used in the production of the connecting seat 4, the positioning seat 2, and the insert block 5.

[0037] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
