Description

Technical Field

[0001] This utility model relates to the field of exhaust gas detection technology, and in particular to a control mechanism for sampling exhaust gas at the tail end of an exhaust pipe. Background Technology

[0002] When testing existing exhaust gases, the method often involves sampling and collecting air around the exhaust pipe before testing. This results in a low concentration of exhaust gases in the air, which is affected by factors such as air pressure and airflow. Using air sampling around the exhaust pipe to determine the content of toxic and harmful gases in the exhaust gas seriously affects the accuracy and reliability of the test data. Furthermore, conducting real-time sampling at the end of the exhaust pipe is extremely impractical, as the equipment is difficult to reach the end of the pipe and the risks are extremely high.

[0003] Therefore, setting up a sampling mechanism at the end of the pipeline is a common practice in existing technologies. Existing sampling mechanisms are often set inside the discharge pipe, which means that the probe is constantly exposed to high-temperature and corrosive exhaust gas, making it very easy to damage the probe. Therefore, it is necessary to set up a controllable and stable control mechanism on the outer wall of the pipeline to effectively install the gas detector probe. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing a control mechanism for sampling exhaust gas at the tail end of an exhaust pipe.

[0005] This utility model is achieved through the following technical solution: A control mechanism for sampling exhaust gas at the tail end of an exhaust pipe includes a mounting frame, a mounting base, an electric push rod, a control base, a guide base, a retaining shaft, and a control mechanism. The mounting base is fixedly disposed on the bottom inner side of the mounting frame. The electric push rod is mounted on the top of the mounting base. The control base is disposed on the telescopic end of the electric push rod. The guide base is fixedly disposed on the inner side of the mounting frame. The retaining shaft is movably connected to the inner top of the mounting frame. The control mechanism is movably disposed inside the mounting frame. The control mechanism includes a tilting base, a connecting toothed plate, a lifting ladder, and a probe. The connecting toothed plate is fixedly disposed on the back of the tilting base. The lifting ladder is mounted on the inner side of the tilting base. The probe is disposed on the top of the lifting ladder.

[0006] In a preferred embodiment of this utility model, a locking hole is provided in the middle of the connecting toothed plate, and the connecting toothed plate is fixedly connected to the locking shaft through the locking hole in the middle, and the flip seat is locked inside the mounting frame; In a preferred embodiment of this utility model, a toothed groove is provided on the outer side of the top of the control seat, and the toothed groove on the outer side of the top of the control seat engages with the outer teeth of the connecting tooth plate; When the electric push rod controls the control seat to move backward, under the influence of the outer tooth groove on its top, it controls the connecting tooth plate to rotate around the locking shaft, thereby controlling the rotation of the flip seat and making it easier to extend the probe to the top outer side of the exhaust pipe.

[0007] In a preferred embodiment of this utility model, a guide groove is provided on the inner side of the guide seat, and the two sides of the control seat are engaged in the guide groove on the inner side of the guide seat. The guide seat effectively guides and limits the control seat.

[0008] In a preferred embodiment of this utility model, a groove is provided on one side of the mounting bracket to cooperate with the exhaust pipe, and the probe is inclinedly disposed on the top of the lifting ladder; The arc-shaped groove on one side of the mounting bracket facilitates its fixation to the outer surface of the exhaust pipe. Since the tilting seat is tilted when the lifting ladder extends, the tilted probe can better contact the exhaust gas and achieve the ideal detection effect.

[0009] The beneficial effects of this utility model are: The control mechanism for sampling exhaust gas at the tail end of the exhaust pipe is mainly located outside the exhaust pipe. This avoids the gas detector probe being affected by high temperature, corrosive gases, dust, etc. for a long time, thus improving its service life and detection accuracy. The control mechanism allows the ladder that mounts the probe to rotate at a certain angle and rise to the top outside of the exhaust pipe, so that the probe can come into close contact with the exhaust gas, ensuring the detection effect. After storage, the equipment is hidden inside the mounting frame, reducing the impact of the external environment on the entire control mechanism. Attached Figure Description

[0012] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings.

[0013] like Figure 1-3 The control mechanism for sampling exhaust gas at the tail end of an exhaust pipe, as shown, includes a mounting frame 1, a mounting base 2, an electric push rod 3, a control base 4, a guide seat 5, a retaining shaft 6, and a control mechanism 7. The mounting base 2 is fixedly installed on the bottom inner side of the mounting frame 1, the electric push rod 3 is installed on the top of the mounting base 2, the control base 4 is located at the telescopic end of the electric push rod 3, the guide seat 5 is fixedly installed on the inner side of the mounting frame 1, the retaining shaft 6 is movably connected to the inner top of the mounting frame 1, and the control mechanism 7 is movably installed inside the mounting frame 1. The control mechanism 7 includes a flipping base 71, a connecting toothed plate 72, a lifting ladder 73, and a probe 74. The connecting toothed plate 72 is fixedly installed on the back of the flipping base 71, the lifting ladder 73 is installed on the inner side of the flipping base 71, and the probe 74 is located on the top of the lifting ladder 73.

[0014] Specifically, the connecting toothed plate 72 has a locking hole in the middle, and the connecting toothed plate 72 is fixedly connected to the locking shaft 6 through the locking hole in the middle. The flipping seat 71 is locked inside the mounting frame 1. The top outer side of the control seat 4 has a tooth groove, and the tooth groove on the top outer side of the control seat 4 meshes with the locking teeth on the outer side of the connecting toothed plate 72. The inner side of the guide seat 5 is provided with a guide groove, and the two sides of the control seat 4 are locked in the guide groove on the inner side of the guide seat 5. One side of the mounting frame 1 is provided with a groove that cooperates with the exhaust pipe. The probe head 74 is tilted and set on the top of the lifting ladder 73.

[0015] In this embodiment, the entire device is fixed to the outer side of the exhaust pipe end by the mounting bracket 1. The arc groove on one side of the mounting bracket 1 facilitates contact with the exhaust pipe surface, thereby ensuring the fixing effect. When the probe 74 does not need to work, the electric push rod 3 is in the extended state. At this time, the flip seat 71 is locked inside the mounting bracket 1, and the probe 74 is set inside the flip seat 71, so that the entire device can be stored, reducing the volume while ensuring the stability of the device and reducing the impact of the external environment on the device, especially avoiding the influence of airflow in higher areas.

[0016] Furthermore, when the probe 74 needs to operate, the telescopic end of the electric push rod 3 on the top of the mounting base 2 retracts, causing the control base 4 to move downward under the guidance and limit of the guide base 5. The toothed groove on the outer side of the top of the control base 4 engages with the teeth on the surface of the connecting toothed plate 72 on the outer top of the flipping base 71. The control base 4 moves down, causing the connecting toothed plate 72 to rotate, thereby causing the flipping base 71 to rotate and tilt around the connecting locking shaft 6. At this time, the motor at the bottom of the lifting ladder 73 starts. Under the control of the motor, the lifting ladder 73 extends, allowing the probe 74 to extend to the outer side of the top of the exhaust pipe. The exhaust gas will pass through the probe 74, enabling the gas detector to perform accurate exhaust gas sampling and data acquisition, ensuring the accuracy of the detection results.
