Description
Technical field
The utility model relates to a kind of sampling supports for comparing monitoring online convenient for fugitive dust.
Background technique
During the production and constructions such as construction site, concrete mixing plant, pier storage yard and particle that dust on the roads generates
Object pollution is one of the important sources of city haze weather, PM2.5, therefore prevention and treatment to dust pollution and control are environmental protections
Important measures.In order to implement dust pollution control measure conscientiously, further improve ambient air quality, current all kinds of fugitive dust fields
It is fitted with fugitive dust online monitoring instruments greatly.
In order to judge the accuracy of fugitive dust online monitoring instruments monitoring data, verifies and guarantee with fugitive dust on-line computing model
The monitoring data quality of device, according to the requirement of corresponding standard criterion, annual reply is carrying out one with fugitive dust online monitoring instruments
The quality in site of certainty ratio is inspected by random samples and contrastive test.Contrastive test refers to tested fugitive dust online monitoring instruments and standard weights method
Monitoring instrument is placed in same scene, and carries out synchronized sampling in section at the same time, is detected the prison of fugitive dust online monitoring instruments
Measured data is compared with the monitoring data of standard weights method, for judging the standard of tested fugitive dust online monitoring instruments monitoring data
Exactness.
At present in contrastive test, sample devices used in standard weights method is two big flow sampling instruments, and contrastive test is wanted
Sample devices and the thief hatch of tested fugitive dust online monitoring instruments is asked to keep same level height, spacing 1m or so (two big stream
It measures sampling instrument spacing and is greater than 1m).Tested fugitive dust online monitoring instruments are generally mounted to the vehicle in and out port section in fugitive dust place, adopt
Sample open height is maintained at 3.5m ± 0.5m, therefore big flow sampling instrument must be placed on this and highly be sampled, usually to build foot
The mode of hand cradle guarantees synchronized sampling, but has many disadvantages.On the one hand scaffold cumbersome, landing stage of scaffold itself are built
Volume is larger, influences vehicle pass-through or handling, spends human and material resources.If it is narrow that test site periphery place is compared, can
Energy can be because of the stagnation that scaffold can not be built and contrastive test is caused to work；On the other hand two big flow sampling instruments are placed in
Monitoring personnel, which need to stand, on the landing stage of scaffold, when sampling and varying just is convenient to operation on scaffold and guarantees that two big flows are adopted
Sample instrument is opened simultaneously, therefore there are some potential safety problemss.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of sampling support for comparing monitoring online convenient for fugitive dust,
This sampling support overcomes traditional online defect for comparing instrument and setting up, conveniently online to compare monitoring results, improves and compares operation
Efficiency saves and compares the activity duration, reduces security risk.
In order to solve the above technical problems, the utility model convenient for fugitive dust compare online monitoring sampling support include pedestal,
Four support rods, four hounds, lifting sleeve, rocker arm and support platform, the lifting sleeve are vertical in the pedestal
The heart, described four support rod one end are symmetrically articulated with the perimeter, and four hound both ends are hingedly connected to described
Lifting sleeve outer wall and four support rod top surfaces, the rocker arm are set to the lifting sleeve outer wall and lifting sleeve are driven to rise
And decline, the support platform are set to the lifting sleeve top.
Further, the pedestal is rectangular metal framework, and described four support rod one end are articulated with the rectangular metal structure
The center on frame periphery.
Further, this sampling support further includes four feets, and four feets are respectively arranged on four support rods certainly
By the bottom surface held.
Further, this sampling support further includes four universal caster wheels with buckle, described four universal caster wheels with buckle
It is symmetrically set in the bottom surface of the pedestal.
Since the sampling support that the utility model compares monitoring convenient for fugitive dust online uses above-mentioned technical proposal, i.e., originally adopt
Sample bracket includes that pedestal, four support rods, four hounds, lifting sleeve, rocker arm and support platform, lifting sleeve are vertical at
Base center, four support rod one end are symmetrically articulated with perimeter, and four hound both ends are hingedly connected to outside lifting sleeve
Wall and four support rod top surfaces, rocker arm are set to lifting sleeve outer wall and drive lifting sleeve raising and lowering, and support platform is set
In lifting sleeve top.This sampling support overcomes traditional online defect for comparing instrument and setting up, conveniently online to compare monitoring results,
The efficiency for comparing operation is improved, saves and compares the activity duration, reduces security risk.
Detailed description of the invention
The utility model is described in further detail with embodiment with reference to the accompanying drawing:
Fig. 1 is the sampling support structural schematic diagram that the utility model compares monitoring convenient for fugitive dust online；
Fig. 2 is this sampling support collapsed state schematic diagram.
Specific embodiment
Embodiment is as depicted in figs. 1 and 2, and it includes pedestal that the utility model compares the sampling support of monitoring convenient for fugitive dust online
1, four support rods, 2, four hounds 3, lifting sleeve 4, Rocker arm 5 and support platform 6, the lifting sleeve 4 are vertical at institute
1 center of pedestal is stated, four support rods, 2 one end is symmetrically articulated with 1 periphery of pedestal, four hounds, 3 both ends point
Be not articulated with 4 outer wall of lifting sleeve and four 2 top surfaces of support rod, the Rocker arm 5 be set to 4 outer wall of lifting sleeve and
4 raising and lowering of lifting sleeve is driven, the support platform 6 is set to 4 top of lifting sleeve.
Preferably, the pedestal 1 is rectangular metal framework, and four support rods, 2 one end is articulated with the rectangular metal
The center of frame peripheral.
Preferably, this sampling support further includes four feets 7, and four feets 7 are respectively arranged on four support rods 2
The bottom surface of free end.Feet is convenient for sampling support integrated regulation to horizontal position, while increasing the area that lands, and is further promoted
The stability of sampling support.
Preferably, this sampling support further includes four universal caster wheels 8 with buckle, described four universal caster wheels with buckle
