Technical field
The utility model relates to a kind of fixed support of sound meter, more specifically says a kind of sound meter support of determining monitoring site and a certain plane relative height in noise monitoring.
Background technology
Sound environment quality is the key content that in Environmental Impact Assessment of Construction Items and completion of works Detection of Environmental Protection Acceptance Check, relevant administrative responsibile institution and influenced resident pay close attention to, noise monitoring is to determine region sound environment quality situation and industrial enterprise's noise emission important means whether up to standard, in the existing standards system of China, regulation for noise monitoring point position is very concrete: as " standard for acoustic environmental quality " (GB3096-2008) in regulation " open air, the at least 3.5m external pelivimetry of monitoring site distance any reverberation (except ground), more than floor level 1.2m, indoor at noise-sensitive structure, monitoring site is apart from metope and at least 1m of other reflectings surface, and apart from the about 1.5m of window place, apart from ground, 1.2～1.5m is high "." Industrial Enterprise Factory Boundary neighbourhood noise emission standard " be middle regulation " generally; measuring point is selected in out-of-bounds 1m of Factory; the position that height 1.2m is above, the arbitrary reflecting surface of distance is not less than 1m " (GB12348-2008), " when Dang Changjie has enclosure wall and has affected noise-sensitive structure around; measuring point should be selected in out-of-bounds 1m of factory, higher than position more than enclosure wall 0.5m ".Therefore how to confirm monitoring point bit position is particularly crucial for the evaluation of monitoring result.
At present in sound environment quality present situation and Boundary Noise emission monitoring process, staff is in operative norm when relevant regulations, how rule of thumb to come the relative height of monitoring site to judge, also having the relative height that uses conventional tape measure determination sensor position, there is following problem in these methods: one, inaccurate to the judgement of height; Two, measure relative height and increase extra work personnel and workload; Three, Industrial Enterprise Factory Boundary have enclosure wall and around while having affected sensitivity building, cannot accurately select point position.In addition, hand-held sound meter carries out the limitation that noise monitoring existence is larger, and as do not met, the equivalent sound level monitoring of long period requires, the monitoring site (as the position higher than more than enclosure wall 0.5m) of some setting cannot reach etc.These problems and limitation greatly reduce the accuracy of monitoring result.
Utility model content
The utility model is in acoustic current Present Situation of Environmental Quality and Boundary Noise emission monitoring process, to problems such as monitoring site height judgement monitoring site inaccurate and some setting cannot arrive, provide a kind of and determine that monitoring site arrives the sound meter support of certain some relative height, cannot accurately determine that to solve in noise monitoring monitoring site position and hand-held sound meter can not meet the technical matters that relevant monitoring standard requires.
The utility model is that technical solution problem adopts following technical scheme:
The utility model can determine that monitoring site arrives the sound meter support of certain some relative height, and its design feature is: described sound meter support comprises the hollow tubular of placing perpendicular to surface level, the expansion link of placing perpendicular to surface level and the base of horizontal positioned; The front end of described hollow tubular is provided with the set bolt for fixing sound meter; In the pipe of described hollow tubular, being inserted with can be along hollow tubular expansion link in axial sliding, and expansion link is fixed by the stop motion mechanism being contained on hollow tubular; Described expansion link stretches out from the rear end of described hollow tubular, and is fixed on base; On described expansion link, be provided with the scale mark for determining support height.
The utility model can determine that monitoring site arrives the sound meter support of certain some relative height, and its design feature is also: described expansion link is provided with plane of orientation along shaft length direction; Described stop motion mechanism is the thread bush of radially fixing along described hollow tubular, and the screw stretching in hollow tubular is housed in described thread bush, and described screw front end is against the diverse location place of described plane of orientation, forms the sound meter support of differing heights.
The upper end of described plane of orientation is positioned at the maximum scale place of described expansion link.
The length of described hollow tubular is 0.5m.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is intuitively accurate for the interpretation of monitoring site, can obtain quickly and easily the relative height of monitoring site;
2, simple in structure, easy to carry, the easy operating of the utility model;
3, the utility model has reduced noise monitoring staff's working strength and workload;
4, use the utility model can solve the problem that the monitoring site set in noise monitoring process cannot arrive.

Embodiment
As shown in Figure 1, the present embodiment can determine that monitoring site arrives the sound meter support of certain some relative height, is characterized in that: sound meter support comprises the hollow tubular 1 of placing perpendicular to surface level, the expansion link 2 of placing perpendicular to surface level and the base 3 of horizontal positioned; The front end of hollow tubular 1 is provided with the set bolt 4 for fixing sound meter; In the pipe of hollow tubular 1, being inserted with can be along hollow tubular 1 expansion link 2 in axial sliding, and expansion link 2 is fixed by the stop motion mechanism being contained on hollow tubular 1; Expansion link 2 stretches out from the rear end of hollow tubular 1, and is fixed on base 3; On expansion link, be provided with the scale mark for determining support height.
As shown in Figure 2, in concrete enforcement, expansion link 2 is provided with plane of orientation along shaft length direction; Stop motion mechanism is the thread bush 5 of radially fixing along hollow tubular 1, and the screw stretching in hollow tubular is housed in thread bush 5, and screw front end is against the diverse location place of plane of orientation, and the shaft of expansion link 2 is compressed, and forms the sound meter support of differing heights.Plane of orientation is from expansion link front end below to downward-extension, and the cross section, front end place of expansion link is complete circle, and plane of orientation is not set, and can prevent like this expansion link slippage from hollow tubular.The upper end of plane of orientation is positioned at the maximum scale place of expansion link 2, and the cross section, front end place of expansion link is complete circle, and plane of orientation is not set, and can prevent like this expansion link slippage from hollow tubular.
According to actual needs, the length of the present embodiment hollow tubular is 0.5m, and in the time that expansion link 2 pulls out completely, sound meter support height is 1.2m.As shown in Figure 3, the scale value on expansion link is the height value 0.5m that height value that expansion link stretches out hollow tubular adds hollow tubular, is convenient to read.
In use, sound meter is fixed on the set bolt 4 of support front end, then by stentplacement at a plane place, position according to scale value stretching expansion link 2 in hollow tubular 1, adjust the height of sound meter support to satisfy the demand, and then tighten the screw of stop motion mechanism, expansion link is fixed.Monitoring personnel can arrange the height of monitoring site as required, thereby make monitoring result meet the requirement of related specifications; When this sound meter support is specially adapted to the noise monitoring of factory circle, enclosure wall has the situation of sensitive spot outward.
