[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health. With the development of society, more and more environmental protection equipment is used in various industries. In order to ensure that the waste gas treated by environmental protection equipment can meet the emission standards, it is necessary to test the waste gas.

[0003] In the prior art, generally, a detection device is inserted into the discharge port of the factory exhaust gas emission channel for detection. However, this detection method requires a person to hold an extension rod or other object to hang the detection device and place it at the discharge port of the exhaust gas emission channel, and then push the detection device into the exhaust gas emission channel. The entry depth is limited. When the distance to the discharge port is close, the exhaust gas will be slightly mixed with the outside air, and the exhaust gas concentration will be reduced, thereby greatly reducing the detection accuracy.

[0004] To this end, an exhaust emission detection device is proposed. Utility Model Content

[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1-3 As shown, an exhaust gas emission detection device includes a shell 1, a sensor module 2 arranged on the outer wall of the shell 1, and a plurality of moving components 3 arranged in the shell 1.

[0033] The moving component 3 includes a moving wheel 1 5, a connecting plate 7 and a moving wheel 2 9. The moving wheel 1 5 and the moving wheel 2 9 are symmetrically arranged and are both rotatably connected to the connecting plate 7 through an axis 1 6. The connecting plate 7 is located at the symmetry center of the moving wheel 1 5 and the moving wheel 2 9 and is rotatably connected to a pulley 8. The outer walls of the moving wheel 1 5, the moving wheel 2 9 and the pulley 8 are driven by the same transmission belt 1 4. A plurality of driving mechanisms having the same number as the moving components 3 are also arranged in the housing 1.

[0034] Place the entire device at the entrance of the exhaust gas emission channel, and then start the driving mechanism to drive the moving wheel 1 5 and the moving wheel 2 9 to move along the inner wall of the channel, thereby driving the entire device to move deep into the exhaust gas emission channel, and then use the sensor module 2 to detect the exhaust gas. In this embodiment, the specific number and function of the sensor module 2 are not specifically limited. For example, when it is necessary to detect sulfur dioxide, carbon monoxide, nitrogen dioxide and other gases in the exhaust gas, the sensor module 2 includes a sulfur dioxide gas sensor, a carbon monoxide gas sensor, a nitrogen dioxide gas sensor, etc.

[0035] The device is provided with multiple groups of moving components 3, and the moving components 3 can drive the entire device to move deep into the exhaust gas emission channel. The exhaust gas concentration deep in the emission channel is higher, which can effectively avoid the reduction of detection accuracy caused by the mixing of exhaust gas and external air, thereby ensuring the accuracy of the detection result.

[0036] In this embodiment, the driving mechanism includes a transmission belt 10 and a tensioning assembly, and the transmission belt 10 is matched with the pulley 8 and the outer wall of the tensioning wheel.

[0037] The tensioning assembly includes a turntable 11 and a second shaft 12. The inner wall of the turntable 11 is provided with a plurality of slide grooves. A slide rod 18 is slidably fitted on the inner wall of the slide groove. An arc plate 19 is fixedly connected to the outer wall of one end of the slide rod 18. The transmission belt 10 is transmission-fitted to the outer wall of the arc plate 19.

[0038] The other end of the slide bar 18 is buckled with a spring 20 , and the other end of the spring 20 is buckled with the inner wall of the slide groove.

[0039] An electric push rod 15 is fixed to the top of the shell 1 by bolts, and the telescopic end of the electric push rod 15 is rotatably connected to the connecting plate 7. Two symmetrically arranged fixed plates 16 are fixedly connected to the inner wall of the shell 1, and the turntable 11 is rotatably connected to the opposite sides of the two fixed plates 16 through the second shaft 12.

[0040] One of the second shafts 12 is fixedly connected to a motor 17 via a coupling, and the motor 17 is fixed to the outer wall of one of the fixing plates 16 via bolts.

[0041] Start the electric push rod 15 to push the connecting plate 7 up, and stop when both the moving wheel 1 5 and the moving wheel 2 9 contact the inner wall of the exhaust gas emission channel. If the inner wall of the emission channel has an inclined surface, taking the moving wheel 1 5 as an example: the moving wheel 1 5 will first contact the lowest point of the pipe wall. As the electric push rod 15 continues to push, the connecting plate 7 is tilted, driving the moving wheel 2 9 to contact the highest point of the pipe wall and maintain a certain pressure. At this time, the overall size of the device is adapted to the inner wall of the channel. When the electric push rod 15 pushes the connecting plate 7 to rise or fall, the slide bar 18 and the arc plate 19 drive the transmission belt 2 10 to deform under the elastic force of the spring 20, so that the reliable transmission of the transmission belt 2 10 can be ensured as the displacement of the pulley 8 changes. When ready, start the motor 17 to drive one of the turntables 11 and the shaft 2 12 to rotate, and cooperate with the transmission belt 2 10 to drive the pulley 8 to rotate. The pulley 8 drives the moving wheel 1 5 and the moving wheel 2 9 to rotate through the transmission belt 1 4, and drives the device as a whole to move along the inner wall of the exhaust gas emission channel with the cooperation of the remaining moving components 3.

[0042] The device is provided with a connecting plate 7 and an electric push rod 15, and the electric push rod 15 is used to drive the connecting plate 7 to rise and fall, so as to adjust the positions of the moving wheel 1 5 and the moving wheel 2 9, so that the device can be applied to exhaust gas emission channels of different sizes, thereby improving the flexibility and applicability of the device.

[0043] The device is provided with a slide bar 18, an arc plate 19 and a spring 20. When the pulley 8 rises and falls with the connecting plate 7, the slide bar 18, the arc plate 19 and the spring 20 cooperate to cause the transmission belt 10 to deform, thereby ensuring reliable transmission of the transmission belt 10, and the motor 17 does not need to move, thereby avoiding damage caused by movement and entanglement of the wiring harness.

[0044] In this embodiment, a control box 13 and a battery 14 are disposed in the housing 1, and the sensor module 2, the battery 14, the electric push rod 15 and the motor 17 are all electrically connected to the control box 13. The battery 14 is used to power the sensor module 2, the electric push rod 15 and the motor 17.

[0045] Embodiment 2:

[0047] The exhaust gas emission detection device is also used in conjunction with a remote controller, which is communicatively connected to the control box 13 .

[0048] The device can be conveniently controlled by a remote controller, which is a prior art and will not be described in detail.

[0049] Working principle: When the device is in use, the entire device is placed at the discharge port of the exhaust gas emission channel, and then all the electric push rods 15 are started by the remote control to drive the connecting plate 7 to rise until the moving wheel 1 5 and the moving wheel 2 9 contact the inner wall of the emission channel and maintain a certain pressure. At this time, the overall size of the device is adapted to the inner wall of the channel. Then the remote control is used to start the motor 17 to drive one of the turntables 11 and the second shaft 12 to rotate, and the transmission belt 2 10 drives the pulley 8 to rotate. The pulley 8 drives the moving wheel 1 5 and the moving wheel 2 9 to rotate through the transmission belt 1 4. With the cooperation of the remaining moving components 3, the entire device is driven to move along the inner wall of the exhaust gas emission channel and move to the deep part of the exhaust gas emission channel, and the sensor module 2 is used to detect the exhaust gas.

Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
