Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

In the following description, the terms "left", "right", "upper", "lower", "front", "rear", "inner" and "outer" are relative terms, and are not intended to be exhaustive.

An exhaust emission detection device, referring to fig. 1, includes a base 1. The base 1 is hollow. The lower side of the base 1 is provided with a connection valve 8 for connection with an exhaust gas discharge pipe. The upper side of the base 1 is provided with a detection mechanism 3 and an exhaust pipe 2. The upper end of the detection mechanism 3 is communicated with an air pump 5. The air extracting pump 5 is communicated with an air outlet pipe 6.

Referring to fig. 2, a shutoff valve 21 is provided in the exhaust pipe 2. The shutoff valve 21 is used to control communication of the exhaust pipe 2 with the base 1. The detection mechanism 3 is provided with a collection cavity 31. The lower end port of the collecting cavity 31 is provided with an interception block 41 matched with the cross section size of the collecting cavity. The interception block 41 is provided with a plurality of ventilation holes 42. The ventilation holes 42 are distributed in a circular shape in the center of the interception block 41. The inner walls of the two sides of the collecting cavity 31 are provided with sliding grooves 33. The slide groove 33 is provided with a slide block 34 in a sliding manner. The slider 34 is made of a magnetic member. An electromagnet 35 is arranged at the lower end of the chute 33. The detection mechanism 3 is provided with a power module, and the power module is electrically connected with the electromagnet 35. A slide 43 is arranged between the two slide blocks 34. The center of the slide plate 43 is provided with a through hole 44. The underside of the slide plate 43 is provided with plugs 45 matching the position, size, shape, number of the ventilation holes 42. A pressure detection meter 36 and a detection module 35 are arranged in the collection cavity 31. The pressure detection meter 36 and the detection module 35 are electrically connected with the power supply module. The detection module 35 is in signal connection with the suction pump 5 and the shut-off valve 21.

A one-way valve 7 is arranged in the air outlet pipe 6 to prevent external air from entering the collection cavity 31.

The detection means 3 may be set with a detection time interval such that it detects the exhaust gas every time a period of time elapses. When the detection mechanism 3 detects exhaust gas, the power supply module does not supply power like the electromagnet 35. Due to the vacuum in the collection chamber 31, the exhaust gases will push 43, separating the plug 45 from the vent 42. The exhaust gas enters the collection chamber 31. When the pressure detection meter 36 detects that the pressure value is not changed any more, the control power supply module supplies power to the electromagnet 35, the electromagnet 35 attracts the sliding block 34 to approach, the sliding block plate 43 moves downwards, and the blocking piece 45 seals the ventilation hole 42. The detection module 35 detects the waste gas in the collection cavity 31 rapidly, if the detection result meets the standard, the stop valve 21 is kept in an open state, the waste gas is continuously discharged to the outside from the exhaust pipe 2, and the exhaust pump 5 pumps the waste gas in the collection cavity 31 out through the air outlet pipe 6. If the detection result does not meet the standard, the detection module 3 sends a signal to the stop valve 21, the stop valve 21 is closed, so that the waste gas cannot be discharged to the outside, and meanwhile, corresponding information is sent to related responsible personnel to perform corresponding processing.

The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art.
