Description
Technical field
The present invention relates to unmanned plane environmental monitoring application field, is specifically that one kind is used to fix chimney pollution thing monitoring opium pipe
The device of feeler lever.
Background technology
Currently, air pollution, which has become, endangers one of killer of human health.Among these, industrial chimney pollutant, bag
The discharge of toxic gas and tiny particles content is included, occupies most ratios of air pollution.The atmosphere pollution of enterprise steal arrange,
Live generally existing is put steathily, and it is abnormal severe, China's prevention and control of air pollution is seriously hindered with administering.
However, current country lacks the air pollution emission on-site law-enforcing regulation technique and equipment of efficient quick.Existing work
The monitoring of industry chimney atmosphere pollution relies primarily on artificial climb up and monitoring mouth is reserved in the middle part of chimney, extracts a certain amount of gaseous sample,
Artificial to climb down chimney, the mode that sample analysis is carried out under line is carried out.The shortcomings that this method one is that high-altitude evidence obtaining is dangerous high, is needed
Manually to climb up, climb down；Second, disguised poor, factory few row can even not arrange within the monitoring period, be closed with reaching to check and accept
The purpose of lattice；Third, law enforcement supervisory efficiency is relatively low, every chimney needs experience to climb up, sampled, climbing down, multiple mistakes are analyzed under line
Journey, whole process are time-consuming more, it is difficult to meet the quick law enforcement supervision in current atmospheric disposal of pollutants scene there is an urgent need to.
At this stage, UAV flight's enviromental monitoring equipment carries out the report of pollutant field monitoring and few.Patent
CN104155954A proposes a kind of municipal engineering method of environmental monitoring based on unmanned plane, main to monitor engineering site in city
In noise and dust concentration, it is mainly cruised by setting course line, passes through the noise level monitor being mounted on unmanned plane
And dust detector, engineering site is monitored.Patent CN 204807134U have invented a kind of MAV airborne industries
Stove dusty gas and granular material discharged detecting system, the system are made up of data acquisition module, power module and transport module,
Three parts module is integrated on one piece of circuit board, can easily carry on Small Civil unmanned plane.Above-mentioned two patent exists
The blank of unmanned plane environmental monitoring has been filled up to a certain extent, but is directed to unmanned plane and is supervised applied to the contamination data of industrial chimney
Survey, at present not clear and definite method.
The content of the invention
To overcome the shortcomings of to there is no in the prior art industrial chimney pollutant, and existing side are monitored on-line using unmanned plane
Method on-site law-enforcing regulation technique is inefficient, enforcing law evidence obtaining is difficult, pollutant scene quantify to be not easy clearly, high-altitude evidence obtaining it is dangerous
Property it is high, do not possess concealed problem, the present invention proposes a kind of device for being used to fix chimney pollution thing monitoring opium pipe feeler lever.
The present invention includes hanger, snap ring, opium pipe feeler lever and hanging plate.Wherein, the length of the hanger is 2~3m.The extension
One end of plate is arranged on the end face on the hanger top by rotating bar and top link, and makes the hanging plate and the hanger
Between can produce relative rotation；The other end of the hanging plate is cantilevered fashion.Described opium pipe feeler lever is fixedly connected by snap ring
