Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flue gas monitoring, specifically to a sampling probe for flue gas monitoring. Background Technology
[0002] Many factories generate a lot of flue gas during production. When emitting, they need to comply with relevant emission standards. Before emission, the flue gas needs to be monitored. The existing flue gas emission monitoring sampling probes can basically meet the daily needs, but there are still some shortcomings that need to be improved.
[0003] For example, a sampling probe for flue gas emission monitoring with authorization announcement number "CN221280737U" solves the problem that existing flue gas emission monitoring sampling probes, which are exposed to the pipeline for a long time, are prone to dust and dirt accumulation on the outside of the flue gas and blockage inside the flue gas collection hole. The above-mentioned probe can drive the top cover to rotate through a drive motor, so that the flue gas collection hole can be exposed to the outside. The flue gas collection hole can effectively monitor flue gas emissions. The top cover can drive the cleaning cotton strip on the movable plate to rotate to the flue gas collection hole. During the rotation, the cleaning cotton strip cleans the dirt on the outside of the flue gas collection hole. Considering that the existing flue gas emission monitoring sampling probes are completely exposed, the surface is easily scratched or damaged by collisions with external objects, resulting in aesthetic and economic losses. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing sampling probes for flue gas emission monitoring are easily scratched or damaged when exposed to external objects, resulting in aesthetic and economic losses. Therefore, this invention proposes a sampling probe for flue gas monitoring.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling probe for flue gas monitoring, comprising a base and a fixing hole, wherein the fixing hole is machined on the inner wall of the side end of the base, the inner wall of the base abuts against a rubber clip, the end of the rubber clip is fixedly connected to the outer shell, the inner wall of the outer shell is machined with a vent hole, and a cleaning mechanism is connected to the middle of the base.
[0006] Preferably, the cleaning mechanism includes an electric telescopic rod, the tail of which is threadedly connected to the base, the output end of which is fixedly connected to a connecting plate, the end of which is fixedly connected to a square frame, and the outer wall of which is fixedly connected to multiple cotton strips.
[0007] Preferably, the outer wall of the swab is slidably connected to the vent hole, the lower end of the base is fixedly connected to the mounting frame, and the outer wall of the outer shell is connected to a protective mechanism.
[0008] Preferably, the protective mechanism includes a screw, the upper end of which is fixedly connected to the outer shell, and the end of which is threadedly connected to an internal threaded block, the upper end of which abuts against the protective cover.
[0009] Preferably, the inner wall of the mounting frame abuts against the sampling probe.
[0010] The sampling probe for flue gas monitoring proposed in this utility model has the following advantages: the protective cover on the outside of the outer shell provides a certain distance from the outer shell, which can play a role in shielding and protecting against collisions with external foreign objects, thus mitigating damage to the surface and interior of the outer shell. When scratches appear on the surface of the protective cover, the internal threaded block can be unscrewed from the screw, and the protective cover can be separated from the outer shell, allowing for cleaning and replacement of the protective cover, effectively avoiding affecting the aesthetics and economic losses.

[0018] The present invention will be further described below with reference to the accompanying drawings:
[0019] Example 1:
[0020] Please see Figure 1-6In this embodiment, a sampling probe for flue gas monitoring includes a base 1 and a fixing hole 2. The fixing hole 2 is machined on the inner wall of the side end of the base 1. The inner wall of the base 1 abuts against a rubber block 3. The end of the rubber block 3 is fixedly connected to the outer shell 4. The inner wall of the outer shell 4 is machined with a ventilation hole 5. A cleaning mechanism 6 is connected to the middle of the base 1.
[0021] The cleaning mechanism 6 includes an electric telescopic rod 601. The output end of the electric telescopic rod 601 extends and retracts, driving the square frame 603 on the connecting plate 602 to move up and down. The cotton strips 604 on the outside of the square frame 603 can wipe and clean the ventilation holes 5. The tail of the electric telescopic rod 601 is threaded to the base 1. The model of the electric telescopic rod 601 is determined according to actual needs and can meet the working requirements. The output end of the electric telescopic rod 601 is fixedly connected to the connecting plate 602. The end of the connecting plate 602 is fixedly connected to the square frame 603. The outer wall of the square frame 603 is fixedly connected to multiple cotton strips 604.
[0022] The outer wall of the cotton swab 604 is slidably connected to the vent 5, the lower end of the base 1 is fixedly connected to the mounting frame 7, and the outer wall of the outer shell 4 is connected to the protective mechanism 8. The protective cover 803 outside the outer shell 4 provides a certain distance from the outer shell 4, which can play a protective role in the face of collision with external foreign objects. The protective mechanism 8 includes a screw 801, the upper end of the screw 801 is fixedly connected to the outer shell 4, the end of the screw 801 is threadedly connected to the internal thread block 802, the upper end of the internal thread block 802 is pressed against the protective cover 803, and the inner wall of the mounting frame 7 is pressed against the sampling probe 9. The sampling probe 9 is an environmental protection flue gas sampling probe M1102.
[0023] The protective cover 803 on the outside of the outer shell 4 is at a certain distance from the outer shell 4. It can play a role in shielding and protecting against collisions with foreign objects, and alleviate damage to the surface and interior of the outer shell 4. When scratches appear on the surface of the protective cover 803, the internal thread block 802 can be turned to remove it from the screw 801, and the protective cover 803 will be separated from the outer shell 4. This allows the protective cover 803 to be cleaned and replaced, effectively avoiding affecting the aesthetics and economic losses.
[0024] Working principle:
[0025] The entire unit is fixedly installed in the flue gas monitoring area by passing external screws through the fixing holes 2 on the base 1. At this time, the vent holes 5 on the outer shell 4 are in a state of air flow. When flue gas is present, the external flue gas comes into contact with the sampling probe 9 and is drawn in by the internal air pump. The internal filter, made of titanium alloy, intercepts impurities in the flue gas, allowing the flue gas to be introduced into the downstream analysis instrument for measuring the concentration of various gases in the flue gas. The gas concentration is then transmitted to the data terminal via the network, achieving the effect of monitoring the surrounding flue gas. The external power supply of the electric telescopic rod 601 is intermittently connected, and the electric telescopic rod 601 starts to work. The output end of the electric telescopic rod 601 extends and retracts, driving the square frame on the connecting plate 602. The 603 moves up and down, and the cotton strip 604 on the outside of the square frame 603 can wipe the vent 5 to prevent the vent 5 from being blocked by foreign objects. At the same time, the protective cover 803 on the outside of the outer shell 4 has a certain distance from the outer shell 4, which can play a role in shielding and protecting against collisions with foreign objects. Tightening the internal thread block 802 to remove it from the screw 801 separates the protective cover 803 from the outer shell 4, which can be used to clean and replace the protective cover 803. Manually pressing the rubber clip 3 causes it to deform and pull the outer shell 4 downward, so that the rubber clip 3 moves downward from the base 1 and detaches, exposing the mounting frame 603 inside the base 1. This can also be used to replace the sampling probe 9 to ensure that the flue gas monitoring is in normal working order.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
