Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figures 1-6 This utility model provides a sampling and collection mechanism for monitoring exhaust gas from stationary pollution sources, including a collector 1, a support base 2, two fasteners, a support cylinder 3, and an auxiliary mechanism. A support rod 4 is located below the collector 1, with transverse screws 5 at both ends. A longitudinal screw 6 is located below the support base 2. The support rod 4 is rotatably connected to the support base 2 via the transverse screws 5 and is located within the support base 2. The two fasteners are fitted onto the corresponding transverse screws 5 and abut against the support base 2. The screws are located within the support cylinder 3. This design uses the collector 1 to monitor exhaust gas from stationary pollution sources, primarily by installing a non-methane total hydrocarbon (NMCH) continuous monitoring system. These systems are typically integrated into a NMCH continuous monitoring system, which consists of a NMCH monitoring unit, a flue gas parameter monitoring unit, and a data acquisition and processing unit. It should be noted that the collector 1 is existing technology, so its structure and working principle will not be described in detail here.

[0022] In this specific embodiment, the auxiliary mechanism includes a threaded sleeve 7, a motor 8, and a mounting cover 9. A driven gear 10 is provided on the outer side of the threaded sleeve 7, and a limiting ring 11 is provided on the inner side of the threaded sleeve 7. A driving gear 12 is provided at the output end of the motor 8. The support cylinder 3 has a limiting groove 13. The threaded sleeve 7 is rotatably connected to the support cylinder 3 and is fitted onto the support cylinder 3, with the limiting ring 11 located within the limiting groove 13. The threaded sleeve 7 is also threadedly connected to the longitudinal screw 6 and is fitted onto the longitudinal screw 6. The motor 8 is fixedly connected to the mounting cover 9 and is located below the mounting cover 9. The mounting cover 9 is fixedly connected to the support cylinder 3 and is fitted onto the outer side of the support cylinder 3. The driving gear 10... 2 meshes with the driven gear 10 and is located inside the mounting cover 9. In this design, the threaded sleeve 7 rotates on the support cylinder 3, and the longitudinal screw 6 can be adjusted up and down under the action of the threaded sleeve 7. Moreover, the threaded structure ensures that the sampler will not change after adjustment. This design can automatically maintain the height without continuous operation by the operator. This not only saves manpower but also makes the sampling process smoother and more efficient. This method solves the technical problem that adjusting the height of the sampling mechanism through the cooperation of gears and teeth requires continuous control of the rotating rod by the operator if the height of the sampling mechanism needs to be kept unchanged. This method is too time-consuming and laborious, thus reducing the practicality and convenience of the device.

[0023] The support cylinder 3 has a polygonal rod 14 at its inner bottom and a polygonal groove 15 inside the longitudinal screw 6. The polygonal rod 14 is located inside the polygonal groove 15. The arrangement of the polygonal rod 14 and the polygonal groove 15 can ensure that the longitudinal screw 6 can move stably up and down inside the support cylinder 3, thereby preventing it from rotating and improving the stability and reliability of the entire mechanism.

[0024] Secondly, the outer side of the threaded sleeve 7 is provided with a plurality of anti-slip protrusions 16, and the plurality of anti-slip protrusions 16 are located at the end of the threaded sleeve 7 away from the driven gear 10. The anti-slip protrusions 16 can increase the friction between the hand and the threaded sleeve 7, preventing slippage when the threaded sleeve 7 is manually rotated. This helps to provide a better grip and control when the height of the collector 1 needs to be manually adjusted.

[0025] Furthermore, the sampling and collection mechanism for monitoring exhaust gas from stationary pollution sources also includes a support ring 17 and a base plate 18. Multiple reinforcing rods 19 are provided on the outer side of the support ring 17, and multiple casters 20 are provided below the base plate 18. The support ring 17 is fixedly connected to the support cylinder 3 and is fitted onto the outer side of the support cylinder 3, and is also located below the mounting cover 9. The multiple reinforcing rods 19 are respectively fixedly connected to the base plate 18 and are located on the outer side of the base plate 18. The base plate 18 is fixedly connected to the support cylinder 3 and is located below the support cylinder 3. The support ring 17 enhances the stability and load-bearing capacity of the entire sampling and collection mechanism, and the casters 20 on the base plate 18 allow the mechanism to be easily moved and positioned to different monitoring points.

[0026] In addition, the fastener includes a retaining pad 21 and a knob sleeve 22. The knob sleeve 22 has a threaded groove 23, which is adapted to the transverse screw 5. The retaining pad 21 is bonded to the knob sleeve 22 and is located at one end of the knob sleeve 22. The knob sleeve 22 is threadedly connected to the corresponding transverse screw 5 and is sleeved on the transverse screw 5. The transverse screw 5 is located in the threaded groove 23. The retaining pad 21 abuts against the support base 2. By adjusting the position of the knob sleeve 22 on the transverse screw 5, the retaining pad 21 abuts against the support base 2, so that the angle of the collector 1 after adjustment can be fixed. This design allows the angle of the collector 1 to be precisely adjusted and fixed as needed.

[0027] When using this utility model, by starting the motor 8, the motor 8 drives the driving gear 12 clockwise. The driving gear 12 meshes with the driven gear 10, and the threaded sleeve 7 rotates under the action of the driven gear 10. At the same time, the setting of the limiting ring 11 and the limiting groove 13 can prevent the threaded sleeve 7 from disengaging from the support cylinder 3. The longitudinal screw 6 moves continuously upward under the action of the threaded sleeve 7 and the polygonal rod 14, thereby realizing the adjustment of the height of the sampler. The thread setting can ensure that the height of the sampler does not change after adjustment. In addition, when the motor 8 fails and needs to be disassembled for maintenance, the threaded sleeve 7 can be rotated by multiple anti-slip protrusions 16 to adjust the height of the sampler, thereby avoiding the situation of being unusable. This method solves the technical problem that the height of the sampling mechanism can be adjusted by the engagement of gears and teeth. However, if the structure needs to keep the height of the sampling mechanism unchanged, the operator needs to continuously control the rotating rod, which is too time-consuming and laborious, thus reducing the practicality and convenience of the device.

[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
