Detailed description of the invention
For making the purpose of this utility model, technical scheme and beneficial effect clearly, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail。
As shown in Figure 1 and Figure 2, this utility model provides a kind of mining portable anemometry device, including base 1, described base 1 upper vertical is provided with expansion link 2, the bottom of its expansion link canned paragraph 21 is hinged with base 1, the upper end of expansion link extendable temple members 22 is provided with clamping device 3, clamping device 3 and expansion link 2 removably connect, clamping device 3 is provided with anemometer 5, the rear of described expansion link 2 is provided with support bar 4 obliquely, the upper end of support bar 4 is hinged with the upper end of expansion link canned paragraph 21, and the lower end of support bar 4 and base 1 are abutted against。As shown in Figure 4, described base 1 is provided with annular groove 7, can slide in the bottom of its support bar 4 in annular groove 7。Described base 1 is provided with multiple block 6 that can be used for and stop support bar 4 bottom to be slided, and described block 6 is respectively positioned on the top of annular groove 7, and described block 6 is all fixed with base 1 and is connected。
When air flows in tunnel, wind speed being unevenly distributed on roadway section, adequately measuring the mean wind speed of roadway, the method generally adopted has fix point method and circuit method two kinds。Fix point method has 9 methods and ten two point methods, and circuit method has four-wire method, six collimation methods and roundabout eight collimation methods。As it is shown in figure 5, illustrate for the four-wire method wind detection method in circuit method below。
As shown in Figure 1, during use, base 1 is placed on the ground in tunnel, expansion link 2 is vertically erected, expansion link extendable temple members 22 is stretched out from expansion link canned paragraph 21, it is connected fixing with the upper end of expansion link extendable temple members 22 for the left end of clamping device 3, anemometer 5 is clamped in clamping device 3, in the present embodiment, anemometer 5 adopts automatic voice number reporting Intelligent Wind Speed meter, expansion link extendable temple members 22 is risen after adjusting suitable position, make expansion link extendable temple members 22 fix with expansion link canned paragraph 21。Now opening support bar 4, slides in the bottom of support bar 4 in annular groove 7, is adjusted to suitable block 6 position, to ensure the stability of whole device。
First, opening power, arrange voice automatic number-sounding interval time (such as 5s interval time, the measurement time be 60s or interval time 10s, the measurement time is 120s)；Secondly, next distinguished and admirable towards in tunnel of the impeller 51 of anemometer 5, press " beginning " the key operation button 53 on anemometer 5, distinguished and admirable impeller 51 rotates, according to anemometer 5 automatic voice number reporting, successively from 1. → 2. → 3. →...→Point at the uniform velocity moves anemometer (as shown in Figure 5), when anemometer 5 voice counting " 12 ", presses " stopping " key operation button 53 and terminates this measurement, and anemometer 5 records measurement result automatically。For ensureing the accuracy measured, same section surveys wind number of times no less than three times, and three measurement result relative erroies, less than 5%, take its meansigma methods as measurement result (VIndicated airspeed)。If measuring relative error more than 5%, illustrating to survey wind result undesirable, anemometer 5 automatically identifies and rejects this measurement data, need to add and once survey wind, until qualified；Finally, pressing " reading wind " key operation button 53, anemometer 5 automatically calculates and corrects, thus obtaining tunnel mean wind speed (VLane is equal) and air quantity, so far, this measuring point is surveyed wind and is terminated。
If it is relatively larger to run into tunnel noise during measurement, when not hearing anemometer 5 count off, it is possible to insert earphone inside the earphone jack 54 of anemometer 5。In addition the upper surface of anemometer 5 is provided with and prevents dust from entering, the protective cover 55 of blocking acoustical generator。
After one measurement terminates, device dismantled, fold and put in workbox later, rush for next one measurement and click on row measuring wind speed, repeat aforesaid operations。
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described。Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed utility model。This utility model claims scope and is defined by appending claims and equivalent。
