Plug-in tail gas monitoring device and monitoring method for automobile tail gas pipe

Abstract

The invention provides a plug-in tail gas monitoring device and monitoring method for an automobile tail gas pipe. The device comprises a gas collecting mechanism, a wind speed sensor and a tail gas detector, wherein the gas collecting mechanism comprises a mounting base, a rotary lifting assembly and a gas suction assembly, and the rotary lifting assembly comprises a driving part and a lifting part which are connected with each other. The gas suction pipe is arranged on the rotating frame, and the rotating frame is in engaged connection with the driving pinion through the driven gearwheel, sothat the gas suction pipe can rotate within a certain range, the gas suction range of the gas suction pipe is enlarged, and the problem of large monitoring error caused by the fact that the gas suction pipe only absorbs gas in a fixed direction is avoided; furthermore, a wind speed sensor is arranged on the mounting base, when the measured value of the wind speed sensor is larger than a preset wind speed threshold value, the gas collecting mechanism cannot be started, and the situation that the monitoring device cannot conduct effective monitoring due to the fact that tail gas flows fast whenthe wind speed is too high is avoided. Therefore, the problems that the monitoring device is ineffective in operation and energy waste is caused can be avoided.

Description

Technical field[0001]The invention relates to the technical field of automobile exhaust monitoring, in particular to a plug-in exhaust monitoring device and a monitoring method for automobile exhaust pipes.Background technique[0002]With the improvement of people's living standards, cars have become one of the indispensable and important means of transportation in our lives, and more and more people and families buy private cars as a means of transportation. However, the increase in the number of cars has aggravated the deterioration of our surrounding environment, especially the exhaust generated during the driving of cars, which seriously pollutes the air environment. Although China has strict regulations on vehicle exhaust emission standards, the driver cannot monitor the quality of the vehicle exhaust during driving; therefore, it is necessary to monitor the vehicle exhaust in real time so that the driver is aware of the exhaust emission and timely maintains and maintains the veh...

AI Technical Summary

Problems solved by technology

Although my country has strict regulations on vehicle exhaust emission standards, drivers cannot monitor the quality of vehicle exhaust in motion; therefore, it is necessary to monitor vehicle exhaust in real time to enable drivers to know the exhaust emissions and to maintain and maintain the vehicle in a timely manner. Maintenance, for example, in a vehicle-mounted vehicle exhaust monitoring device whose patent application number is 201711330018.8, the real-time monitoring of vehicle exhaust is realized by fixing the probe of the exhaust detector on the outlet end of the vehicle exhaust pipe; but the device still has deficiencies , For example, when the car climbs a slope or changes gears, or even some misoperations, the exhaust emissions will suddenly increase. At this time, the exhaust gas detector does not detect the real exhaust data of the car, which leads to the problem of untrue reference data; At the same time, since the device is fixed on the exhaust pipe of the automobile through an external clamping block, when it is applied to some scenarios where the exhaust pipe of the automobile is hidden in the body, the device will not be able to adapt, resulting in reduced applicability of the device
