Description

Technical Field

[0001] This utility model relates to the field of gas analyzer technology, specifically a semiconductor laser gas analyzer. Background Technology

[0002] In the environmental protection industry, as global attention to greenhouse gas emissions and air quality continues to rise, there is a need for accurate monitoring of various gases such as methane, ammonia, and carbon dioxide. Semiconductor laser gas analyzers can meet the needs of identifying methane hotspots, monitoring regional greenhouse gas concentrations, and online monitoring of air quality, playing an important role in environmental protection work.

[0003] From a routine maintenance perspective, after a period of operation, critical components such as internal sensors and circuits may be corroded by environmental factors such as dust and moisture. Regular cleaning, inspection, and calibration are necessary. Traditional equipment often features complex casing designs and lacks convenient disassembly mechanisms. For example, some equipment uses numerous small screws to secure the casing, requiring maintenance personnel to spend considerable time finding and removing them. This increases the workload and difficulty of routine maintenance, making simple cleaning tasks tedious and lengthy, and potentially impacting the equipment's normal lifespan due to excessive time commitment. Utility Model Content

[0004] The purpose of this invention is to provide a semiconductor laser gas analyzer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a semiconductor laser gas analyzer, comprising:

[0006] The analyzer itself;

[0007] A transmission assembly is housed within the analyzer body. The transmission assembly includes a threaded rod rotatably connected to the analyzer body, a connecting rod threadedly connected to the threaded rod, a rotating column fixedly connected to the connecting rod, an opening on the rotating column, a first fixed rod slidably connected to the rotating column, a fixed frame fixedly connected to the first fixed rod, a clamping plate fixedly connected to the rotating column, and a threaded rod fixedly connected to the clamping plate. The threaded rod is rotatably connected to the analyzer body.

[0008] A dust-proof assembly is placed inside the analyzer body. The dust-proof assembly includes a second fixing rod fixedly connected to a clamping plate, a transmission plate fixedly connected to the second fixing rod, and a baffle plate fixedly connected to the transmission plate.

[0009] Furthermore, a rotating shell is fixedly connected to the threaded rod, and a slot is provided on the analyzer body, with the rotating shell rotatably connected to the slot on the analyzer body.

[0010] The above technical solution is adopted: by opening a slot on the rotating shell, it is convenient to limit the rotation position of the rotating shell body.

[0011] Furthermore, the analyzer body has heat dissipation holes on its top, and the shield is slidably connected to the side of the analyzer body top near the heat dissipation holes.

[0012] The above technical solution is adopted: by opening heat dissipation holes on the top of the analyzer body and covering them with a baffle plate, when the rotating column is driven to slide towards the side closer to the rotating shell in the fixed frame, it can drive the baffle plate to move and expose the heat dissipation holes.

[0013] Furthermore, the connecting rod is slidably connected within the fixed frame.

[0014] The above technical solution is adopted: by setting a connecting rod, it is convenient to use the threaded rod connected to the connecting rod to drive the rotating column.

[0015] Furthermore, a fixing plate is fixedly connected inside the analyzer body.

[0016] The above technical solution involves a fixed plate fixedly connected inside the analyzer body. During use, the clamping plate slides onto the fixed plate, which acts as a limiting plate to fix the analyzer housing.

[0017] Furthermore, the fixing frame is fixedly connected to the fixing plate.

[0018] The above technical solution is adopted: by setting a fixed frame and a fixed plate to slide together, the clamping plate can slide onto the fixed plate during use, thereby limiting the position of the fixed frame.

[0019] Furthermore, the analyzer body has an opening, and the second fixing rod is slidably connected to the opening on the analyzer body.

[0020] The above technical solution is adopted: by setting an opening on the analyzer body, the second fixing rod is prevented from being blocked during use.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, the rotating shell serves as the starting point for operation. When the rotating shell is turned, it drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the connecting rod, the connecting rod slides in a specific direction within the fixed frame, thereby linking the rotating column. The rotating column ensures stability during rotation through its own opening and sliding engagement with the first fixed rod. Furthermore, its fixedly connected clamping plate moves outward with the rotation. When the clamping plate engages with the fixed plate and is pulled backward, it tightly secures the internal components of the analyzer body. The entire process is convenient and significantly improves installation efficiency compared to traditional, complex installation methods.

[0023] In this invention, during installation, as the clamping plate moves, the second fixing rod fixedly connected to it drives the transmission plate to move backward synchronously, thereby driving the shielding plate to move backward, exposing the heat dissipation holes on the top of the analyzer body. This ensures a good heat dissipation channel when the equipment is running normally, and effectively prevents dust from entering through the heat dissipation holes when installing internal components or during non-heat dissipation periods. It flexibly balances heat dissipation and dust prevention requirements according to the equipment's operating status. Attached Figure Description

[0034] 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. Example

[0035] like Figures 1-5 As shown, this utility model provides a technical solution: a semiconductor laser gas analyzer, comprising:

[0036] Analyzer body 1;

[0037] The transmission assembly 2 is located inside the analyzer body 1. The transmission assembly 2 includes a threaded rod 21 rotatably connected to the analyzer body 1, a connecting rod 26 threadedly connected to the threaded rod 21, a rotating column 24 fixedly connected to the connecting rod 26, an opening on the rotating column 24, a first fixed rod 25 slidably connected to the rotating column 24, a fixed frame 22 fixedly connected to the first fixed rod 25, a clamping plate 23 fixedly connected to the rotating column 24, and the threaded rod 21 fixedly connected to the clamping plate 23. The threaded rod 21 is rotatably connected to the analyzer body 1.

[0038] Dust shielding assembly 3 is placed inside the analyzer body 1. Dust shielding assembly 3 includes a second fixing rod 31 fixedly connected to the clamping plate 23, a transmission plate 32 fixedly connected to the second fixing rod 31, and a baffle plate 33 fixedly connected to the transmission plate 32.

[0039] In this invention, the rotating shell 27 serves as the starting point for operation. When the rotating shell 27 is turned, it drives the threaded rod 21 to rotate. Since the threaded rod 21 is threadedly connected to the connecting rod 26, the connecting rod 26 slides in a specific direction within the fixed frame 22, thereby linking the rotating column 24. The rotating column 24, on the one hand, ensures stability during rotation by sliding with the first fixed rod 25 through its own opening; on the other hand, the clamping plate 23, which is fixedly connected to it, moves outward with the rotation. When the clamping plate 23 is engaged with the fixed plate 4 and pulled backward, the internal components of the analyzer body 1 are tightly fixed. The entire process is convenient and greatly improves installation efficiency compared to traditional complex installation methods.

[0040] Furthermore, such as Figures 1 to 5As shown, a rotating housing 27 is fixedly connected to the threaded rod 21. A slot is formed on the analyzer body 1, and the rotating housing 27 is rotatably connected within this slot. The slot provides a dedicated rotation path for the rotating housing 27, ensuring it rotates along a predetermined trajectory when the operator rotates it, preventing wobbling or deviation and ensuring precise and stable operation of the subsequent transmission components 2. Furthermore, even after long-term use, if components wear or loosen, the rotating housing 27 can quickly return to its original position thanks to the slot, facilitating calibration by maintenance personnel, reducing maintenance difficulty, and ensuring stable equipment operation.

[0041] The analyzer body 1 has heat dissipation holes on its top. A shielding plate 33 is slidably connected to the top of the analyzer body 1 near the heat dissipation holes. When the equipment is running, the rotating column 24 slides, causing the shielding plate 33 to move synchronously, precisely controlling the opening and closing of the heat dissipation holes. When heat dissipation is needed, the shielding plate 33 moves away, allowing heat to dissipate quickly and maintaining a suitable temperature for the components. When heat dissipation is not needed or the environment is dusty, the shielding plate 33 closes the heat dissipation holes, preventing dust from entering, protecting the internal precision components, and extending the equipment's lifespan.

[0042] The connecting rod 26 is slidably connected within the fixed frame 22. The rotation of the threaded rod 21 causes the connecting rod 26 to slide smoothly in the direction defined by the fixed frame 22, achieving precise power transmission without power loss or directional deviation. During assembly, it is easy to insert into the fixed frame 22, reducing difficulty; during maintenance, it can be easily removed, shortening repair time and improving equipment maintainability.

[0043] A fixed plate 4 is fixedly connected inside the analyzer body 1. The operation of the transmission component 2 causes the clamping plate 23 to move outward, which serves as a stable limiting target, allowing the clamping plate 23 to be accurately positioned. This ensures that the outer shell is firmly fixed, preventing the outer shell from loosening due to operating vibration, and also ensures the overall structural stability of the equipment, so that the internal structure remains compact and orderly when subjected to external forces.

[0044] The fixed frame 22 is fixedly connected to the fixed plate 4. During assembly, the fixed frame 22 provides a path for the clamping plate 23 to slide. The clamping plate 23 slides along it to the fixed plate 4 and reaches the back limit fixed frame 22, ensuring the stability of the transmission component 2 after completing the shell fixing action and avoiding failure due to poor shell fixing during operation.

[0045] The above solution also has the problem that the second fixing rod 31 can be stuck in the analyzer body 1, such as Figure 1 , Figure 2 , Figure 3 As shown, the analyzer body 1 has an opening, and the second fixing rod 31 is slidably connected in the opening on the analyzer body 1. The opening on the analyzer body 1 is specially designed for the second fixing rod 31, so that the second fixing rod 31 can be inserted into the analyzer body 1 from the end near the rotating shell 27 during the installation stage.

[0046] Working principle: such as Figures 1-5 As shown, when in use, the staff first fixes the base plate of the analyzer body 1 to the fixing frame 22. After the internal components of the analyzer body 1 are installed, the fixing plate 4 is inserted into the analyzer body 1 and the fixing plate 4 is fixed to the bottom of the outer wall of the analyzer body 1 with bolts.

[0047] During this process, the second fixing rod 31 is inserted into the analyzer body 1 through the opening at the top of the analyzer body 1. The rotating shell 27 is turned, causing the rotating shell 27 to drive the threaded rod 21 to rotate. This causes the connecting rod 26 to slide towards the threaded rod 21 within the fixing frame 22. During this process, under the limiting action of the second fixing rod 31, the rotating column 24 will not rotate. The first fixing rod 25 slides on the opening in the rotating column 24. At this time, the rotating column 24 will be driven to rotate, causing the clamping plate 23 to be driven to move outward, lock onto the fixing plate 4, and pull the fixing plate 4 backward, so that the fixing plate 4 is connected more tightly within the analyzer body 1, thus completing the installation of the analyzer body 1.

[0048] The second fixing rod 31 is fixed by screwing bolts into the transmission plate 32. During the process of the clamping plate 23 being moved, the transmission plate 32 will be moved backward, which will cause the shielding plate 33 to be moved backward, exposing the opening on the top of the analyzer body 1. At this time, heat dissipation can be carried out normally, and dust will be prevented from entering through the heat dissipation port when installing internal components.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
