Description
Technical field
This utility model belongs to field of wind power equipment, is specifically related to a kind of blade vortex generator mounting and positioning device.
Background technology
The blade of wind power generating set is installed vortex generator, it is possible to improving the lift of blade, and improve lift-drag ratio, thus improving the performance of blade, wind power generating set generated energy being had certain castering action. Conventional vortex generator structure is as it is shown in figure 1, vortex generator 1 includes base, and pan frontward end is airflow inlet limit 11, and dual-side 12 upwards vertically extends to form two profiles. In the installation process of vortex generator, the positioning precision problem of vortex generator directly affects its lifting degree to wind power generating set generated energy. Vortex generator installation site on blade is generally determined by three parameters: 1) exhibition of vortex generator is to coordinate, and exhibition is to referring to from root of blade to blade tip; 2) the tangential coordinate of vortex generator, tangential refers to from blade inlet edge to blade trailing edge; 3) angle of vortex generator and blade centreline, the i.e. angle of the airflow inlet limit of vortex generator and blade centreline, blade centreline refers to vertical vane root end face and points to the straight line of blade tip.
Under normal circumstances, the process installing vortex generator can be divided into the following steps:
1) determine that vortex generator exhibition on blade is to installation site with tape measure, from with the vertical direction of root of blade end face to blade tip orientation measurement, determine the installation site scope of vortex generator, such as within the scope of from root of blade flange 5m～10m, some vortex generators are installed, between vortex generator, to design in advance, there is certain installing space along exhibition.
2) determine the vortex generator tangential installation site on blade with tape measure, the tangential installation site that same exhibition is upwards vortex generator is connected into a line, i.e. installation reference line;
3) along installation reference line, installing space according to design, measure successively from start of installation to terminal and vortex generator is installed, ensureing the airflow inlet limit of each vortex generator and the angle of the installation reference line angle equal to the vortex generator designed in advance with blade centreline simultaneously.
In step installed above, in step 3) in, need to adopt related tool to measure distance and setting angle, simultaneously because the installation quantity of vortex generator is relatively larger, therefore 1 is had the disadvantage that when mounted) need to measure installing space when each vortex generator is installed and determine installation site, so comparing and expend time in, if in work high above the ground, it is then longer that it installs required time; 2) no matter it is work high above the ground or Ground Operation, when determining vortex generator setting angle, it usually needs first measure with bevel protractor, indicate setting angle position, then vortex generator is installed again. Do so ratio is time-consuming, and installation accuracy cannot guarantee that.
Utility model content
Therefore, this utility model installs inconvenient, the consuming time longer and unwarrantable technical problem of installation accuracy for vortex generator in prior art, purpose is in that to provide one can reduce the vortex generator set-up time, improves the blade vortex generator mounting and positioning device of installation accuracy.
Blade vortex generator mounting and positioning device of the present utility model includes a base plate, described base plate side is true edge, the opposite side that described true edge is relative has a positioning port, described positioning port includes a limit, location and a laminating limit, limit, described location and the joining on described laminating limit are the installation anchor point of vortex generator to be installed, and limit, described location is identical with the angle of blade centreline with described vortex generator with the angle of described true edge.
A segment distance is had between joining and the described true edge on limit, described location and described laminating limit, when using described blade vortex generator mounting and positioning device location and installation, the reference for installation alignment blade inlet edge direction of measurement and positioning in advance can be translated identical distance, making when described true edge aligns with installation reference line, the joining on limit, described location and described laminating limit is placed exactly in installation site. Now only need to by the airflow inlet limit of described vortex generator and the laminating of limit, described location, moving described vortex generator again makes airflow inlet limit end points overlap with the joining on limit, described location and described laminating limit, both can ensure that the accuracy of described vortex generator installation site, it is possible to ensure the accuracy of setting angle.
Limit, described location is identical with the angle of described vortex generator inlet side and described vortex generator side with the angle on described laminating limit. When the airflow inlet limit of described vortex generator and the laminating of limit, described location, described vortex generator side also can be fitted with described laminating limit, and location and installation is convenient accurately.
The length of described true edge is identical to installing space with the exhibition of vortex generator, can quickly measure and position the exhibition of described vortex generator to installation site with this.
Described blade vortex generator mounting and positioning device also includes leader, is fixedly arranged on described base plate, sets up the easily operated installation of described handle.
Positive progressive effect of the present utility model is in that: blade vortex generator mounting and positioning device of the present utility model limit in advance the length of described true edge can measure easily and fast open up to installation site, and by the angle of fixing described true edge and limit, described location, tangential installation site and setting angle to vortex generator position guiding, avoid the complicated processes of angular surveying, not only can efficiently reduce the vortex generator set-up time, and position and the angle accuracy that vortex generator is installed can be effectively improved.From actual effect, the set-up time reduces 20%～25%, and installation accuracy improves also obvious. Thus the vortex generator lifting effect for wind turbine power generation amount can be ensured.
