Description

Technical Field

[0001] This application relates to the field of gas sampling, and more particularly to a gas sampling device for gas detection. Background Technology

[0002] Gas detection plays a crucial role in numerous fields, including industrial production, environmental monitoring, and safety protection. Before conducting gas detection, sampling the tank is a key step in obtaining accurate gas samples. Tank sampling is widely used in industries such as chemical engineering, energy, and environmental protection. For example, it's used to monitor the gas composition within reaction tanks in chemical production and to collect gas samples from exhaust emission tanks in environmental monitoring. In practical gas sampling work, when multiple samples are required, the tank is typically fixed in a specific location in the environment and held for a certain period to ensure that representative gas samples are collected.

[0003] After removing the canister from the device, it is often difficult to accurately position it in the target environment. Currently, operators mostly need to hold the canister by hand or use external tools (such as supports, clamps, etc.) to support and position it. This method is not only cumbersome and increases the workload of operators, but also, due to human factors or the instability of external tools, it is difficult to ensure that the canister is accurately and stably fixed in the ideal sampling position during actual operation, thus reducing the convenience of gas sampling. At the same time, this inefficient positioning method also consumes a lot of time, which has a certain negative impact on the overall efficiency of gas sampling, making it impossible to complete the sampling work quickly and efficiently, and failing to meet the growing demand for gas detection.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a drawback in the tank sampling method, which makes it inconvenient to position the sampling tank. Therefore, a gas sampling device for gas detection is proposed to solve the above problems. Utility Model Content

[0005] To address the problem of inconvenient positioning of the sampling tank when sampling gas from a tank, this application provides a gas sampling device for gas detection.

[0006] The gas sampling device for gas detection provided in this application adopts the following technical solution:

[0007] A gas sampling device for gas detection includes a sampling box with a lid installed on its upper surface. A placement groove is formed at the center of the top of the sampling box, and a support frame is placed inside the placement groove. Two fixing inner grooves are formed on both sides of the upper surface of the sampling box near the placement groove, and support rods are placed inside the two fixing inner grooves. A connecting structure is provided between the placement groove and the support frame to fix the support frame above the sampling box. A sliding groove is symmetrically formed on both sides of the upper surface of the support frame, and a limiting slider is movably installed inside the first sliding groove. The tops of the two limiting sliders on the same side extend to the upper surface of the support frame and are welded to connecting plates. Bearing supports are symmetrically fixedly installed on the upper surface of the connecting plates. Movable support rods are rotatably installed inside the bearing supports, and positioning support plates are rotatably installed on the tops of the movable support rods. A clamping mechanism is also provided on the upper surface of the positioning support plates.

[0008] Preferably, the clamping mechanism includes a fixed frame, which is fixedly installed on both sides of the upper surface of the positioning support plate. A second sliding groove is provided at the top center of the fixed frame. A movable block is symmetrically and movably installed inside the second sliding groove. A clamping plate is installed on the top of the movable block extending above the fixed frame. A spring is installed on one end of the movable block extending into the inner wall of the second sliding groove.

[0009] Preferably, the connection structure includes positioning screw holes, which are opened on both sides of the bottom end of the inner wall of the placement groove. The bottom of the outer surface of the support rod is provided with external threads, and the support rod is threadedly connected to the positioning screw holes. Positioning rods are fixedly connected to both sides of the bottom end of the support frame. A groove is opened in the middle of the top end of the support rod, and the positioning rod is threadedly connected to the groove.

[0010] Preferably, the support frame has through-holes at the middle of both sides of the top end, and the connecting plate has a threaded connection at the middle of the top end with a limiting bolt. The bottom of the limiting bolt extends into the limiting hole, and the limiting hole and the limiting bolt are mutually compatible.

[0011] Preferably, the upper surface of the sampling box has several No. 1 fixed inner grooves at both ends, and a gas sampling tank is placed inside the No. 1 fixed inner groove.

[0012] Preferably, limit slots are symmetrically provided on both sides of the inner wall of the placement groove, and a fixing hole is provided through one side of the inner wall of the first slide groove. One side of the limit slider extends through the fixing hole into the interior of the limit slot, and the limit slider and the limit slot are engaged with each other.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The support frame is securely installed above the sampling box through the connecting structure. By using the engagement of the limit slider and the limit slot, as well as the cooperation of the limit bolt and the limit hole, the position of the connecting support plate and related components can be precisely adjusted and fixed, which facilitates the positioning of the sampling tank. This avoids the drawbacks of traditional positioning methods that rely on handheld or external unstable tools, and greatly improves the convenience and accuracy of positioning.

[0015] 2. The spring in the clamping mechanism provides elastic force to the clamping plate, allowing for adaptive clamping and fixing according to the size of the sampling container. This ensures stable fixation of sampling containers of different specifications, enhancing the applicability of the device. Simultaneously, the movable support rod is rotatable, enabling the positioning support plate and clamping mechanism to flexibly adjust their angles to adapt to different sampling environments and container placement requirements.

[0016] 3. The threaded connection between the support rod and the positioning screw hole, and the positioning rod and the groove, ensures a firm and reliable connection between the support frame and the sampling box, guaranteeing the stability of the entire device during use. This ensures that the sampling tank will not shake or shift during sampling, which is beneficial for obtaining accurate gas samples. Attached Figure Description

A fixing hole is provided through one side of the inner wall of the first slide 11. One side of the limiting slider 12 extends through the fixing hole into the limiting slot 24. The limiting slider 12 and the limiting slot 24 are engaged with each other. The tops of the two limiting sliders 12 on the same side extend to the upper surface of the support frame 6 and are welded with connecting support plates 13. The upper surface of the connecting support plates 13 is symmetrically fixed with bearing supports 14. The inside of the bearing supports 14 is rotatably installed with movable support rods 15. The top of the movable support rods 15 is rotatably installed with positioning support plates 16. Limiting holes 22 are provided through the middle of both sides of the top of the support frame 6. The top middle of the connecting support plates 13 is threaded with limiting bolts 23. The bottom of the limiting bolts 23 extends into the limiting holes 22. The limiting holes 22 and the limiting bolts 23 are mutually compatible. The upper surface of the positioning support plates 16 is also provided with a clamping mechanism.

[0024] By installing the support rod 8 onto the sampling box 1 via a threaded connection with the positioning screw hole 9, and then installing the support frame 6 onto the top of the support rod 8 via a threaded connection with the support rod 8 via the positioning rod 10, the position and angle of the connecting support plate 13, the movable support rod 15, and the positioning support plate 16 are adjusted by sliding the limit slider 12 in the first slide groove 11 and the limit slot 24, and by rotating the limit bolt 23 in the limit hole 22. The gas sampling canister 4 to be used is then taken out from the first fixed inner groove 3 and placed between the two clamping plates 20 of the clamping mechanism. The elastic force of the spring 21 is used to make the clamping plates 20 firmly clamp the gas sampling canister 4, so that the gas sampling canister 4 can be sampled stably.

[0025] Reference Figure 3 and Figure 4 The clamping mechanism includes a fixed frame 17, which is fixedly installed on both sides of the upper surface of the positioning support plate 16.

[0029] The implementation principle of a gas sampling device for gas detection according to an embodiment of this application is as follows: In use, the support rod 8 is first installed on the sampling box 1 through a threaded connection with the positioning screw hole 9. Then, the support frame 6 is installed on the top of the support rod 8 through a threaded connection with the positioning rod 10. According to the actual sampling requirements, the position and angle of the connecting support plate 13, the movable support rod 15, and the positioning support plate 16 are adjusted by sliding the limit slider 12 in the first slide groove 11 and the limit slot 24, and by rotating the limit bolt 23 in the limit hole 22. The gas sampling canister 4 to be used is taken out from the first fixed inner groove 3 and placed between the two clamping plates 20 of the clamping mechanism. The elastic force of the spring 21 is used to make the clamping plates 20 firmly clamp the gas sampling canister 4. Through this structural design and operation method, the gas sampling canister 4 can be conveniently and accurately positioned and fixed, meeting the gas sampling requirements in different environments and improving the efficiency and accuracy of gas sampling.
