Description
Technical field
The utility model relates to a kind of leaf angle measuring device of subway tunnel blower fan, belongs to blower fan and ventilating system field of engineering technology.
Background technology
As everyone knows, the subway tunnel blower fan in use when the characteristic of blower fan and actual applying working condition have discrepancy, should be realized the characteristic coupling at blower fan scene by the angle of adjusting blade.And the angular dimension that fan blade is installed is converted into the setting angle of blade after outer garden difference by measuring end of blade and blade height are calculated usually.And this method practical operation bothers very much, again can not continued operation, and intuitive is poor.
The utility model content
In order to address the above problem, the utility model provides a kind of subway tunnel blower fan leaf angle measuring device, this device can be continuously, convenient, intuitively the leaf angle of subway tunnel blower fan is measured.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of subway tunnel blower fan leaf angle measuring device, comprise substrate, protractor, spirit-leveling instrument, measurement module, wherein, substrate center is fixed with a turning axle, protractor is engaged on this turning axle by its center pit activity, the turning axle top is equipped with set nut, and spirit-leveling instrument then is fixed on the protractor, and measurement module is installed in the positive lower end of substrate.
As the further setting of such scheme, described substrate lower end is provided with the locating piece that the location survey template is used, and locating piece is positioned at the top of measurement module.
Described measurement module is fastened on the substrate by three equally distributed screws.
The utility model subway tunnel blower fan leaf angle measuring device, the corresponding measurement module of fan blade with required measurement need be installed on substrate during use, then measurement module is buckled in the end of impeller of blower, tighten set nut when the amount of spin hornwork makes top spirit-leveling instrument be level, the angle that the position quantity hornwork of this moment shows is exactly the angle of fan blade.
When adjusting the angle of fan blade, subway tunnel blower fan leaf angle measuring device is buckled in the end of impeller of blower, protractor is adjusted to the blade angle value position that need adjust to, and tighten set nut, then the moving blade angle.When spirit-leveling instrument reached horizontality, tightening paddle screw, fan blade were just adjusted on the needed angle.
In a word, the utility model subway tunnel blower fan leaf angle measuring device, can be continuously, convenient, intuitively the leaf angle of subway tunnel blower fan is measured, and simple in structure, cost is low.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is a two-way fan blade measurement module structural representation of the present utility model;
Fig. 4 is a unidirectional fan blade measurement module structural representation of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model subway tunnel blower fan leaf angle measuring device comprises substrate 4, protractor 3, spirit-leveling instrument 2, measurement module 6.Wherein, substrate 4 center fixation have a turning axle 11, and protractor 3 is engaged on this turning axle 11 by its center pit activity, and turning axle 11 tops are equipped with set nut 1, and 2 of spirit-leveling instruments are fixed on the protractor 3, and measurement module 6 is installed in the positive lower end of substrate 4.
More quick for the installation that makes measurement module 6, accurately, be provided with the locating piece 5 of location survey template 6 usefulness in substrate 4 lower ends, and locating piece 5 is positioned at the top of measurement module 6.
For making the result who takes measurement of an angle more accurate, measurement module 6 is fastened on the substrate by three equally distributed screws 10.
As shown in Figure 3, Figure 4, the windward side curve of the curve of measurement module 6 and fan blade 8 or fan blade 9 ends matches.Wherein fan blade 8 is two-way blade profile end face, and fan blade 9 is unidirectional blade profile end face.Measurement module 6 can be joined work according to the shape of measuring impeller of blower, and ticks 7, is convenient to select for use at any time.
Now in conjunction with said structure, the actual measurement method of the utility model subway tunnel blower fan leaf angle measuring device is described below:
Impeller of blower 8 that need are measured and adjusted or fan blade 9 are horizontal attitude and place.Being installed on the substrate 4 with fan blade 8 or fan blade 9 corresponding measurement modules 6.Be buckled on the windward side of fan blade 8 or fan blade 9 ends with measurement module 6 then.
When measuring the leaf angle, then need the bubble of amount of spin hornwork 3 in spirit-leveling instrument 2 (when spirit-leveling instrument 2 is level) when the centre position, tighten set nut 1.The measurement module 6 of measurement mechanism is broken away from impeller of blower 8 or fan blade 9, and the angle of indication is exactly the leaf angle of blower fan on the protractor 3 of measurement mechanism.
When adjusting blower fan leaf angle, earlier protractor 3 is adjusted to the blade angle value position that need adjust to, and tighten set nut 1.Unscrew the trip bolt on fan blade 8 or the fan blade 9, rotate fan blade 8 or fan blade 9, when the bubble in the spirit-leveling instrument 2 on the protractor 3 during in the centre position (when spirit-leveling instrument 2 is level), tighten the trip bolt on fan blade 8 or the fan blade 9, this moment, the leaf angle of impeller of blower 8 or fan blade 9 was correctly adjusted on the predefined Ye Jiao position.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
