Existing solar power plant all adopts heat collector to absorb the heat of sunshine; Can follow the tracks of the sun at any time in order to guarantee heat collector; The mode of many at present employing hydraulic controls realizes the upset of heat collector; But hydraulic control system exists manufacturing cost high, maintenance, the shortcoming that maintenance cost is high, and also very high in some very cold areas to the requirement of hydraulic oil.
The utility model content
The purpose of the utility model is, a kind of tracking means of groove type solar is provided, and it adopts electric pushrod, has cheap for manufacturing costly, and maintenance, maintenance cost is low, and does not receive the influence of natural conditions during work.
The technical scheme of the utility model: a kind of tracking means of groove type solar; Comprise supporting leg, mirror support, collector bracket and heat collector, heat collector is fixed on the mirror support through collector bracket, and condenser mirror is installed on the mirror support; The two ends of mirror support are connected with the top of supporting leg through rotating shaft; The bottom of supporting leg fixes on the ground, and mirror support is provided with bearing diagonal, and bearing diagonal is provided with rotating shaft A near an end of condenser mirror; One side of mirror support or the supporting leg of both sides are provided with electric pushrod, and the bottom of electric pushrod flexibly connects the top of electric pushrod and rotating shaft A active link through the inboard of rotating shaft B and supporting leg; Electric pushrod also be located at ground control device and be electrically connected.Adopt electric pushrod to have low cost of manufacture, easy care, keep in repair and receive natural cause to influence little advantage.
In the tracking means of aforesaid groove type solar, condenser mirror adopts the parabolic type minute surface.
In the tracking means of aforesaid groove type solar, heat collector adopts vacuum heat collection pipe.
In the tracking means of aforesaid groove type solar, electric pushrod has auto-lock function.Because electric pushrod possesses auto-lock function, so can improve the wind resistance loading capability of trough type solar heat-collector.
In the tracking means of aforesaid groove type solar, be equipped with pad and setscrew nut on rotating shaft A and the rotating shaft B.Pad and setscrew nut are set effectively prevent the electric pushrod move left and right, thereby avoid the long-time tracking precision problem that easily perforate is ground greatly and then influenced trough type solar heat-collector that uses.
In the tracking means of aforesaid groove type solar, mirror support is provided with angular transducer, and angular transducer is electrically connected with control device.The tracking of heat collector is the tracking angle work that calculates according to heat collector site longitude and latitude and local time through angular transducer; Angular transducer feedback angle information; When angular transducer feedback angle was in correct scope, control device control electric pushrod quit work.
Compared with prior art, the utility model has dwindled construction cost greatly owing to adopt electric pushrod to replace traditional hydraulic cylinder, because electric pushrod need not use hydraulic oil, it is smaller influenced by natural cause when therefore working.Because electric pushrod itself possesses auto-lock function, the ability that groove type heat collector opposing wind carries is strengthened greatly.
