Be elaborated below in conjunction with accompanying drawing each ingredient to the present embodiment:
1) concentric circular tracks 1: follow the tracks of as integrated abutment structure track and the platform that sunshine rotates, the ground concentric circular tracks generally consists of circuit orbit (A, B and C in figure) by concentric circles (depending primarily on the thermal power station system size scales such as photovoltaic generating system or the Stirling) sheet metal of one or more different radii on the level ground.The area of a circle that the circuit orbit of its outmost turns surrounds is exactly that this integrated power generation system is from the total area of motion tracking integrated platform; And the parameters such as the design width of sheet metal and the distance between track are relevant with factors such as load weight and power house integrated system scales, and the turning axle located of the heart " O " is installed on the main shaft that is fixed on ground therein;
2) integrated abutment structure: remain on around main shaft the carrier that moves with the rotational-angular velocity of the earth synchronous rotary on concentric circular tracks as a plurality of solar electrical energy generation load units are installed under automatic tracking system drives, mainly by orthogonal at surface level, the metal pipe material of the certain equally distributed some parallel girders (east-west direction) of spacing and warp girder (North and South direction) forms basic load-carrying members, and rely on the load bearing system that is formed by several passive scroll wheels, passive scroll wheel installation site is corresponding with circular track on ground and be on the concentric circumference of different radii, relevant with factors such as loads apart from the interval each other.In addition, also need to increase (omitting in figure) such as appropriate section dowel, reinforcement and local steel plates according to the requirement of Independent Power Generation cellular installation again.Also have, below garden COD radian outside integrated base station (α=150 °) is located, the umbrella gear bar is installed.

large system for many Stirling heat generating one-of-a-kind systems compositions, taking into full account the high and generator unit of tracking accuracy and be generally the characteristics of 100 square metres of receiving areas, its automatic tracking system can adopt the structure that is similar to photo-voltaic power generation station automatic tracking system integrating device to realize equally, as shown in Figure 5, this system is mainly by three concentrically ringed horizontal rail with the base station that rolls in the above and be with cogged and surface-based motor to form, wherein base station is exactly by mutually vertical and be fixed on roller, the whole base station that the AB CD girder that is connected with rotation axis again and the roller that all are connected by muscle form, motor drives whole base station by gear drive (ragged edge and track are fixed together with ADB radian tooth bar and the base station of shape) and rotates with the angular velocity of 15 ° per hour around rotation axis continuously, thereby keep synchronizeing with rotational-angular velocity of the earth, and in the power house, 48 Stirling solar heat are generated electricity the uniform distributing installations of unit on base station, namely unified being installed on of part more than the herringbone in several units rotated on base station, and due to signal picker and the treatment circuit of whole large system, driver part only shares one and gets final product, make the cost performance of whole power house higher.for example for the Stirling thermal power station of 1MW, need altogether 40 one-of-a-kind system Unitings of 25KW be arranged on diameter be 140 meters (approximately floor areas are 23 mus) have some (as three tracks) concentric circular tracks and respective drive motor and a transmission gear, in the console mode automatic tracking system of the compositions such as support (wherein the pitch angle still can adopt separate unit to drive with linear electric motors driving tracking mode or the unified signal unit that sends), because the ratio unit of drive point and the center of circle (radius) has increased 20 times, linear velocity reaches (3.14*140)/(3600*24)=51mm/S.Utilize roller to rotate on some concentric circular tracks and at this time usually reach loading on of 80 tons of left and right, its advantage is that center of gravity is low, and the drive point linear velocity is large.Adopt gear drive to guarantee that the continuously and smoothly rotates more reliable and stable, and can make again tracker (comprising support) holistic cost and operating cost drop to half of original unit, but in whole large system, each unit must be adjusted at three dimensions its optical axis identical when mounted, this workload is very large, yet in case after installing and debug after normal operation, the whole construction cost in solar power plant and operating cost will significantly descend.
Because the High Precision Automatic tracking performance of the hot generator unit system requirements of Stirling solar, so must be equipped with the pitch angle autotracker on this basis.Since because adopted the console mode structure, and each generator unit area reaches 100 square metres, weight is the 2-3 ton, so it is more worthwhile that independently realize from motion tracking at the pitch angle of each generator unit, concrete as Stirling heat generating console mode cellular system medium dip angular direction automatic tracking system composition is similar.Namely utilize linear electric motors by universal wheel connect driving stem (because condensing body when rotate around the water bottle axle for the driving stem of connection, direction is changing) the direct independent pitch angle of adjusting each condensing body of mode, together with the rotation base station, realize the High Precision Automatic following function of two directions of sunshine.
