Abstract
The utility model discloses a retractable fixed device for testing noise. The device comprises a triangular support, a retractable rod, a timer and a sound level meter, wherein one end of the retractable rod can be inserted into the middle of the triangular support and is fixed by a fixing screw, and the other end of the retractable rod is provided with a 360-degree rotary joint; the sound level meter is fixed on the 360-degree rotary joint; and the timer is arranged on the retractable rod. By the retractable fixed device for testing the noise, a portable handheld sound level meter is used as auxiliary monitoring equipment, and the compatibility is high, so that all handheld noise testers can be mounted, and signal attenuation caused by converting electronic signals is avoided at the same time; and the device is low in cost and high in controllability.
Description
Technical field
The utility model relates to a kind of extension type noise testing stationary installation.
Background technology
At present, China's most of areas noise monitoring also is in the manual monitoring stage, promptly utilizes the hand-held sound meter that has the integration statistical function or the spectrum measurement function is arranged; According to code requirement and monitoring content; On the monitoring site of selecting to configure,, and the transaudient unit of equipment alignings needed the noise source or the noise region of measurement with the support unit of human body as equipment; Measure after configuring the sampling parameter of sound meter simultaneously; At some in particular cases, as: stipulate among the 5.3.3.1 among " industrial enterprise's standard on emission of environmental noise within the boundary of an industrial enterprise " GB12348-2008: when Dang Changjie had enclosure wall and affected noise-sensitive structure arranged on every side, measuring point should be selected in out-of-bounds 1 meter in factory; Be higher than 0.5 meter of enclosure wall, regulation must be provided with measuring point at outdoor 1 meter of noise-sensitive structure among the 5.3.3.2.Same these measuring points are provided with requirement all has embodiment in " standard for acoustic environmental quality " GB3096-2008, " social living environment's noise emission standard " GB22337-2008.There is following shortcoming in the traditional-handwork monitoring:
(1) it is less that the sound meter microphone receives area, when the people hands sound meter, has certain shake, is difficult to keep fixed-direction in the measurement, thereby produce measuring error.
(2) when needs carry out the zone, hand over to do, during the sampling of functional areas long-time continuous, artificial sample is unrealistic, seeks suitable device simultaneously and lays a little comparatively difficult.
(3) in above-mentioned some in particular cases, need the people, perhaps sound meter is stretched out outside window, the safety of monitoring personnel and equipment is had threat for ascending a height.
(4) the old type tube sound meter of producing before some all is not equipped with support.
According to the problem and the situation that exist in these monitoring practices; Some manufacturers are that the sound meter of new model has been equipped with signal-transmitting cable; Receive unit and prestage on the sound meter are extended, thereby solved the problem of the remote sampling of this model sound meter, played certain function.But signal-transmitting cable do not support some old type tube equipment, and there is signal attenuation in transmission cable, and monitoring accuracy is had certain influence.Present most of environmental monitoring department is in the majority with the sound meter old type tube, so this structure popularization is not strong.In addition, some manufacturers have researched and developed the noise automatic monitoring system, but the automatic station of noise is a fixed equipment, and when carrying out noise multimetering or traverse measurement, practicality is not high, and price is comparatively expensive, and are also comparatively strict to building the place restriction.
The utility model content
The purpose of the utility model is providing extension type noise testing stationary installation a kind of simple in structure, easy to operate.
The purpose of the utility model is achieved in that
A kind of extension type noise testing stationary installation; Comprise A-frame, expansion link, timer and sound meter; Said expansion link one end inserts the middle part of A-frame and is fixed by fixed screw; The other end of expansion link is provided with 360 degree swivel adapter heads, and said sound meter is fixed on the said 360 degree swivel adapter heads through the sound meter fixed support, on the said expansion link timer is housed.
Preferably, the said expansion link of the utility model is processed by carbon fibre material.
Preferably, the said expansion link of the utility model is 10 meters.
Preferably, the said expansion link of the utility model is formed by connecting the above body of rod of two joints.
The beneficial effect of the utility model is:
The utility model can be through regulating the height of expansion link and fixed screw and then adjustment sound meter.The sound meter fixed support can be fixed present domestic whole hand-held sound meters, and the utility model also has 360 degree spinfunctions, can make the transaudient unit of noise aim at the sphere meaning angle of taking up an official post.Said expansion link adopts high strength, high rigidity, lightweight section bar manufacturing, light and handy, durable, nothing shake.Said expansion link is designed to multistage extended structure, and maximum extended height satisfies all specific position monitoring needs more than 10 meters.The bottom is an A-frame, has alleviated weight in the time of simplified structure, has reduced structural vibration.The utility model is provided with timer simultaneously, has clocking capability, can make operating personnel grasp monitoring time in detail, the utlity model has to be easy to carry, and lays simply characteristics such as high reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
