Embodiment
Still need to solve because the departing from and the problem departing from for sunshine declination angle causing that revolves round the sun solar hour angle that earth rotation causes for the automatic tracking technique of fixed photoreceptor in solar concentrator.In order to address this problem, the present invention has designed following technical scheme:
Sunshine polar mounts autotracking unit of the present invention comprises solar hour angle follower, declination angle tracking mechanism and is obliquely installed as the condenser 61 towards sunshine, wherein on the sensitive surface of condenser 61, is provided with sunlight signal acquiring device 1; Condenser 61 lower ends link structure by multisection type axle to be fixed, and multisection type axle links structure provides the degree of freedom of solar hour angle rotation and declination tilt adjustment for condenser 61; Solar hour angle follower comprises arc track and is arranged on the railcar on arc track, and between railcar and arc track, be provided with chain drive mechanism, railcar is fixedly connected with the lateral surface of condenser 61; Declination angle tracking mechanism is arranged on solar hour angle follower lower end, for providing oscilaltion stroke to drive whole solar hour angle follower and condenser 61 to carry out declination tilt adjustment.
Based on above architectural feature, below in conjunction with accompanying drawing, wherein a kind of preferred embodiment of the present invention is described in detail:
As shown in Figure 1: multisection type axle links structure and comprises the turning axle 62 that is arranged on upper semisection and the main shaft 63 that is arranged on lower semisection, hinged between turning axle 62 and main shaft 63, between turning axle 62 and condenser 61, is connected by bulb joint bearing.
Referring to Fig. 1 and Fig. 2, in preferred embodiment of the present invention, the arc track 4 of solar hour angle follower comprises track matrix 41, is provided with roller groove 45 in the both sides of track matrix 41, and the upper end of track matrix 41 offers " protruding " font chain 46; Railcar comprises that upper end is provided with the car body of load board 44, is provided with the fast pulley 42 that snaps in described roller groove 45 on car body both sides, and on car body, below load version 44, both sides are provided with movable pulley 43, and movable pulley 43 is along track matrix 41 upper surface two Slideslips; Chain drive mechanism comprises driving chain 32 and the chain drive motor 31 in the chain 46 that is arranged on track matrix 41, and the middle part of load board 44 is connected with driving chain 32 by connecting link 47.The upper surface of load board 44 is directly connected with the lateral surface of condenser 61.The curve shape of track matrix 41 of the present invention is a part for circumference, and corresponding radius of a circle is the distances of track matrix 41 present positions to main shaft 63.Chain drive motor 31 is fixedly installed on the below (as shown in Figure 2) of arc track 4, and driving chain 32 was around arc track one week, and chain drive motor 31 moves to drive railcar to move by chain wheel drive driving chain 32.
Declination angle tracking of the present invention mechanism is as depicted in figs. 1 and 2: it comprises that the pitch angle being fixedly connected with solar hour angle follower lower end adjusts platform 52, and the jacking system 51 of lifting travel is adjusted platform 52 belows and is provided with to provide at pitch angle.This jacking system 51 can adopt kinds of schemes to solve, as linear electric motors, leading screw (manual or electronic) and oil/gas cylinder.This mechanism has ensured that the inclination alpha of condensing body 64 is the local north latitude number of degrees (as shown in Figure 1).
In addition, in order to realize from motion tracking, the present invention also includes a controller 2, this controller 2 gathers the signal of described sunlight signal acquiring device 1, and control the chain drive motor 31 of solar hour angle follower and the jacking system 51 of declination angle tracking mechanism, thereby the solar hour angle to condenser 61 and declination inclination angle regulate.
According to the principle of work of the patent of invention of having obtained the authorization (sunlight signal acquiring devices in a kind of high-precision tracking system: ZL200910254627.9), in the time that sunshine faces condenser irradiation, there is no output signal, but because the earth is equivalent to the sun and exports when continuously motion makes sunshine direction depart from condenser optical axis direction the electric signal that departs from of needs, send after treatment corresponding driving signal, drive motor will drive condenser to realize the corresponding rotation centered by main shaft by gear train.Depart from condenser major axes orientation because the motion in sun rise process causes sunshine direction in a certain moment in for example morning, the electric signal of collection is uploaded to controller by sunshine, processor according to design program calculate and judge after send instruction by output terminal to drive motor, drive motor produces and needs the motion of direction (rotating or translation) according to command request, and then the direction rotation motion of dragging (pushing away) condenser to reduce towards deviate by gear train, be stop motion in 1 o'clock until be reduced to deviate.But in Practical Project, be to be all adjusted to deviate in allowed band according to specific needs.Be exactly specifically that chain drive motor 31 utilizes while rotating the meshing condenser being fixed together with load board 44 in tow of chain is rolled by pressure wheel along slideway, because the curve shape of this slideway is the part in garden week, and all radiuses in corresponding garden are the distance of slideway present position to main shaft; Itself be exactly that the sun rises every day---the mathematical model track of landing, so directly realized the rotation following function of two angles of solar hour angle and pitch angle.In addition, the earth encloses the formed deviate that revolves around the sun taking 1 year as the cycle totally 47 0angle changing, thus just very little for every day, seldom action and can received energy conventionally; Even, in the lower occasion of ask for something tracking accuracy (direct illumination of underground garage sunshine), can also save whole mechanisms that pitch angle rotation is followed the tracks of according to engine request, thereby significantly reduce system cost.
To make the as a whole present situation that is effectively realized Salar light-gathering and application by actuation movement for the condensing body in current common solar automatic tracking system and photoreceptor, this polar mounts sunlight automatic tracking device of design has been realized require to maintain static the automatic tracking function of realizing sunshine under (the sunshine introducing cylinder of tunnel or underground garage) condition at photoreceptor completely by analysis, is applied to hypogee enhancement mode direct illumination has created condition for sunshine is high efficiency.
