[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3 The utility model provides a pollution source exhaust gas detection device, comprising a detection device body 1, a first air intake pipe 2 being provided on one side of the detection device body 1, an exhaust pipe being provided on the other side of the detection device body 1, and a plurality of detection probes 12 being provided inside the detection device body 1;

[0025] A second air intake pipe 3 is provided on one side of the first air intake pipe 2. A rotatable disc 4 is provided between the first air intake pipe 2 and the second air intake pipe 3. The disc 4 is provided with a plurality of slots 5. A filter plate 6 is provided inside the slots 5. A first motor 8 is fixedly provided on one side of the detection device body 1. A driving block 7 is provided at the output end of the first motor 8. The driving block 7 is engaged with the disc 4.

[0026] In this embodiment, the exhaust gas from the pollution source to be detected is injected into the detection device body 1 through the second air inlet pipe 3 and the first air inlet pipe 2. During this process, the injected exhaust gas from the pollution source will be filtered by the filter plate 6. At this time, the particles in the exhaust gas from the pollution source will adhere to the filter plate 6, which can prevent excessive impurities from adhering to the inner wall of the detection chamber inside the detection device body 1, and will not cause impurities to adhere to the outer wall of the detection probe 12, thereby ensuring the accuracy of the detection device body 1 in detecting the exhaust gas from the pollution source. Moreover, since the detection probe 12 is located at multiple positions inside the detection device body 1, the exhaust gas from the pollution source in the detection device body 1 can be detected from multiple directions, which can further improve the accuracy of the detection device body 1 in exhaust gas detection.

[0027] In this structure, when the exhaust gas from the pollution source enters the interior of the detection device body 1, the first motor 8 is started, which can cause the driving block 7 to drive the disc 4 to rotate a certain angle, so that the filter plate 6 can be moved out between the first air inlet pipe 2 and the second air inlet pipe 3. At this time, the disc 4 can block the first air inlet pipe 2, thereby preventing the exhaust gas from the pollution source in the detection device body 1 from leaking at the first air inlet pipe 2. Specifically, a sealing ring can be provided at the joints between the first air inlet pipe 2 and the second air inlet pipe 3 and the disc 4 to ensure the sealing of the joints between the first air inlet pipe 2 and the second air inlet pipe 3 and the disc 4.

[0028] And when one of the filter plates 6 has been used for a period of time, the disc 4 is rotated by a certain angle so that the other filter plate 6 can re-enter between the first air inlet pipe 2 and the second air inlet pipe 3, making it convenient to replace different filter plates 6.

[0029] In this embodiment, a positioning shaft 9 is rotatably provided in the middle part of the disc 4, and one end of the positioning shaft 9 is fixed to one side of the detection device body 1. The positioning shaft 9 can provide a positioning effect for the disc 4 on one side of the detection device body 1, thereby improving the stability of the disc 4 during use.

[0030] In this embodiment, the filter plate 6 is bonded inside the empty slot 5 , and the bonding method has the advantage of convenient assembly.

[0031] Furthermore, dustproof stickers are bonded to both sides of the filter plate 6. The dustproof stickers can prevent the filter plate 6 located on the outside from being attached with excessive dust and impurities.

[0032] In this embodiment, a second motor 10 is fixedly provided at the upper end of the detection device body 1, and an output end of the second motor 10 is provided with a stirring shaft 11 located inside the detection device body 1. Starting the second motor 10 can make the stirring shaft 11 rotate inside the detection device body 1, which can make the pollution source exhaust gas in the detection device body 1 more evenly mixed, and can further improve the accuracy of the pollution source exhaust gas during detection.

[0033] Furthermore, the first motor 8 and the second motor 10 are both servo motors.

[0034] In the description herein, it should be noted that relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, the terms "include," "comprise," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
