Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a portable environmental monitoring sampling gun fixing device. Background Technology

[0002] Sampling guns are frequently used in stationary source exhaust gas sampling for environmental monitoring. They are mostly cylindrical and used for sampling from exhaust chimneys. The main method of use is to insert the sampling gun into the chimney's detection port, and then collect and test the exhaust gas using accessories integrated on the sampling gun tube, such as temperature, pressure, heat tracing pipes, and detachable sampling heads. Currently, according to the requirements of national pollution discharge permit self-monitoring and relevant pollutant monitoring standards, monitoring many conventional pollutants in stationary source exhaust gas requires long-term sampling or taking multiple samples at equal intervals, which takes a considerable amount of time and places a significant workload on field personnel. Firstly, current sampling guns on the market have many integrated functions and attachments, making them quite heavy. Prolonged holding by personnel cannot guarantee the stability of the sampling gun. If not held, the sampling gun is prone to tipping or twisting after insertion into the detection port, posing a risk to monitoring results and sampling safety. Secondly, while methods using vertical telescopic metal supports or other forms of supports to fix the sampling gun exist, these methods have limited application locations, and the supports are bulky and inconvenient to carry.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 This is a front view of the portable environmental monitoring sampling gun fixing device provided by this utility model; Figure 2 yes Figure 1 A schematic diagram of the internal structure of the portable environmental monitoring sampling gun mounting device shown. Figure 3 yes Figure 1 Left view of the portable environmental monitoring sampling gun mounting device shown; Figure 4 This is a schematic diagram of the installation of the portable environmental monitoring sampling gun fixing device and sampling port provided by this utility model; Figure 5This is another installation diagram of the portable environmental monitoring sampling gun fixing device and sampling port provided by this utility model. The portable environmental monitoring sampling gun fixing device includes a fixing cylindrical sleeve 11, a clamping assembly 12, multiple clamping guide grooves 13, and multiple fixing clips 14. The fixing cylindrical sleeve 11 includes two opposing semi-circular arc plates. One side of the two semi-circular arc plates is rotatably connected by a hinge 111, and the other side is fixedly connected by a locking assembly 112. The two semi-circular arc plates 111 together form a receiving cavity 113 with a circular cross-section. The clamping assembly 12 is disposed in the receiving cavity 113. The multiple clamping guide grooves 13 are evenly disposed along the radial direction of the fixing cylindrical sleeve 11 on the outer peripheral surface of one end of the fixing cylindrical sleeve 11, and one of the clamping guide grooves 13 is disposed on the top of the fixing cylindrical sleeve 11. The multiple fixing clips 14 are respectively slidably disposed on the multiple clamping guide grooves 13, and each fixing clip 14 includes a fixing plate 14. 1. A clamping locking bolt 142 and a locking nut 143 are provided. The fixing plate 141 is located on the side of the clamping guide groove 13 away from the clamping assembly 12. One end of the clamping locking bolt 142 passes through the clamping guide groove 13 and is fixedly connected to the fixing plate 141. The locking nut 143 is threadedly connected to the other end of the clamping locking bolt 142. The clamping locking bolt 142 can move along the length direction of the clamping guide groove 13 and can rotate around its own axis. By moving the clamping locking bolt 142 on the clamping guide groove 13, the fixing plate 141 can be moved along the clamping guide groove 13, thereby adjusting the position of the fixing plate 141 on the clamping guide groove 13. By rotating the clamping locking bolt 142, the fixing plate 141 can be rotated around the clamping guide groove 13. The portable environmental monitoring sampling gun fixing device of this utility model can be adjusted according to the form and size of the sampling port 15. By adjusting the position of each fixing clip 14 on the corresponding clip guide groove 13, the fixing plate 141 and the corresponding clip guide groove 13 cooperate to form a clamping structure for fixing the fixing cylindrical sleeve 11 on the sampling port 15. Then, by tightening the corresponding locking nut 143, the fixing cylindrical sleeve 11 is fixed on the sampling port 15. After adjusting the depth of the environmental monitoring sampling gun 16 entering the sampling port 15, the environmental monitoring sampling gun 16 is fixed by the clamping assembly 12. This effectively solves the problem of on-site fixing of different types of sampling guns and different types of sampling ports, improves sampling accuracy, and has a simple structure, small size, low manufacturing cost, and is easy to use on-site, reducing the labor intensity of monitoring personnel.

[0023] Further, the clamping assembly 12 includes an upper pressure plate 121, a lower pressure plate 122, two push rod bolts 123, and a fixing seat 124. The upper pressure plate 121 and the lower pressure plate 122 are arranged opposite each other in the middle of the receiving cavity 113 along the axial direction of the fixed cylindrical sleeve 11. The top of the upper pressure plate 121 is provided with a hollow groove 125 extending along the axial direction of the fixed cylindrical sleeve 11. The two push rod bolts 123 are arranged side by side and spaced apart along the axial direction of the fixed cylindrical sleeve 11. The lower end of the top bolt 123 passes sequentially through the top of the fixed cylindrical sleeve 11 and the hollow groove 125 and extends into the hollow groove 125. The top bolt 123 is threadedly connected to the fixed cylindrical sleeve 11 and the hollow groove 125 respectively, and a limit nut 126 is threadedly fixedly connected to the bottom of each top bolt 123. The fixing seat 124 is located at the bottom of the lower pressure plate 122 and is fixedly connected to the bottom of the lower pressure plate 122 and the inner wall of the fixed cylindrical sleeve 11 respectively. In this structure, by using the top bolt 123 and the hollow groove 125 located at the top of the upper pressure plate 121, the height of the upper pressure plate 121 can be adjusted, allowing the clamping assembly 12 to fix different types of sampling guns, thus improving the applicability of the portable environmental monitoring sampling gun fixing device.

[0024] Furthermore, there are two fixing seats 124, which are arranged side by side and spaced apart along the axial direction of the fixing cylindrical sleeve 11. By providing two fixing seats 124, the stability of the lower pressure plate 122 is improved.

[0025] Furthermore, both the upper pressure plate 121 and the lower pressure plate 122 are arc-shaped plates, and the curvature of the upper pressure plate 121 and the lower pressure plate 122 is adapted to the environmental monitoring sampling gun 16. This structure allows the upper pressure plate 121 and the lower pressure plate 122 to better clamp the environmental monitoring sampling gun 16, improving the stability of the environmental monitoring sampling gun 16 and thus improving sampling accuracy.

[0026] Furthermore, the inner sides of both the upper pressure plate 121 and the lower pressure plate 122 are provided with anti-slip plastic bushings 127, which can further improve the stability of the environmental monitoring sampling gun 16.

[0027] Furthermore, the fixing clip 14 also includes a flat washer 144, which is sleeved on the clip locking bolt 142 and located on the side of the locking nut 143 near the clip guide groove 13. By providing the flat washer 144, the contact area between the locking nut 143 and the clip guide groove 13 can be increased, preventing the locking nut 143 from loosening and improving the locking effect of the locking nut 143.

[0028] Furthermore, the opposing sidewalls of the fixing plate 141 and the clamping guide groove 13 are provided with anti-slip serrations 145, which can improve the clamping effect of the fixing plate 141 and the clamping guide groove 13 on the sampling port 15 and improve the stability of the portable environmental monitoring sampling gun fixing device during use.

[0029] Furthermore, there are three clamping guide grooves 13, one of which is located at the top of the fixed cylindrical sleeve 11. The centerline of the clamping guide groove 13 coincides with the diameter of the end face circle of the fixed cylindrical sleeve 11, and the included angle between two adjacent clamping guide grooves 13 is 120°. This structure allows the fixed cylindrical sleeve 11 to better bear the force, improving the stability of the portable environmental monitoring sampling gun fixing device during use.

[0030] When using the portable environmental monitoring sampling gun fixing device of this utility model, first open the fixing cylindrical sleeve 11, place the environmental monitoring sampling gun 16 on the lower pressure plate 122, then close the fixing cylindrical sleeve 11 and tighten the locking assembly 112; then, depending on the form and size of the sampling port 15, and for cases where the sampling port 15 has a connecting flange structure 17, adjust the position of each fixing clip 14 on the corresponding clip guide groove 13 so that the fixing plate 141 and the corresponding clip guide groove 13 cooperate to form a mechanism for fixing the fixing cylindrical sleeve 16. A clamping structure is fixed to the connecting flange structure 17 outside the sampling port 15. Then, by tightening the corresponding locking nut 143, the clamping structure clamps the outer edge of the connecting flange structure 17, thereby fixing the fixed cylindrical sleeve 11 to the sampling port 15. Then, after adjusting the depth of the environmental monitoring sampling gun 16 entering the sampling port 15, the environmental monitoring sampling gun 16 is fixed by the clamping assembly 12. If there is no connecting flange structure 17 outside the sampling port 15, the position of each fixing clip 14 on the corresponding clip guide groove 13 is adjusted. The device is positioned such that the fixing clip 14 can enter the exhaust chimney 18 connected to the sampling port 15 through the sampling port 15. Then, the position of the portable environmental monitoring sampling gun fixing device is adjusted so that the clip guide groove 13 near the side wall of the exhaust chimney 18 close to the fixing clip 14 is in contact with the outer side of the exhaust chimney 18 pipe wall. Then, by rotating the clip locking bolt 142, the fixing plate 141 is rotated, so that the fixing plate 141 and the clip guide groove 13 cooperate to form a clamping structure for fixing the fixing cylindrical clip 11 to the exhaust chimney 18. Then, by tightening the corresponding locking nut 143, the clamping structure clamps the wall of the exhaust chimney 18 at the sampling port 15, thereby fixing the fixed cylindrical sleeve 11 to the sampling port 15. Then, after adjusting the depth of the environmental monitoring sampling gun 16 entering the sampling port 15, the environmental monitoring sampling gun 16 is fixed by the clamping assembly 12. This design effectively solves the problem of fixing different types of sampling guns with different types of sampling ports on site, improves sampling accuracy, and has a simple structure, small size, low manufacturing cost, and is easy to use on site, reducing the labor intensity of monitoring personnel. Furthermore, when adjusting the position of each of the fixing clips 14 on the corresponding clip guide groove 13 to clamp the outer edge of the connecting flange structure 17 or the wall of the exhaust chimney 18 at the sampling port 15, first adjust the fixing clips 14 on the clip guide groove 13 located at the top of the fixing cylindrical sleeve 11, and after fixing, adjust and fix the other fixing clips 14. This allows the fixing cylindrical sleeve 11 to better bear the force.
