Abstract
The invention discloses a mounting structure of a parabolic dish concentrator of a sterling concentrated solar power system. The mounting structure comprises a stand column, a specular surface bracket (1) and a specular surface (2), wherein the specular surface bracket (1) and the specular surface (2) are in dish shapes, and a fan-shaped opening groove (3) is formed in the radial direction; the stand column consists of an upper stand column (5) and a lower stand column (6), wherein the upper stand column (5) is mounted on the lower stand column (6) through a rotating flange (7); the cross section of the upper stand column (5) is trapezoidal; the upper stand column (5) penetrates through the opening groove (3); the specular surface bracket (1) is mounted on a rotating shaft at the top of the upper stand column (5). According to the mounting structure disclosed by the invention, the cross section of the upper stand column is changed into trapezoidal, so that a dimension required by forming the groove in the specular surface can be effectively reduced, and besides, the mass of the stand column is greatly reduced; therefore, the transporting and the mounting are more convenient.
Description
Technical field
The present invention relates to a kind of dish-style Stirling electricity generation system, particularly relate to the mounting structure of sun's rays reflection device in system.
Background technology
Dish-style Stirling photo-thermal power generation technology is the mode the highest currently with solar energy generating efficiency, and the efficiency of its heat generating is the highest can reach 25%-34%.The most ripe dish-style Stirling electricity generation system is designed by Cleanergy company of Sweden, and China used this design to build up first dish-style Stirling photo-thermal Demonstration Station of China in 2012.
But this technology not large-scale promotion the most at home later, restricts key factor of its development and install exactly cost, its huge space frame structure makes transport and assembling all have difficulties.
The concentrator of this dish-style Stirling electricity generation system is wanted after being installed on column can pitching, therefore to slot, and existing column design is all a cylinder, therefore a bigger groove is opened required for, especially the biggest by the ratio shared by the groove of ectocentral position, such intensity effect is very big, needs to increase extra reinforced structure and quality.
Summary of the invention
The technical problem to be solved in the present invention: for the problem that existing dish-style concentrator fluting is bigger, it is provided that the column of a kind of trapezoid cross section, to reduce fluting area.
Technical solution of the present invention:
A kind of dish-style concentrator mounting structure of Stirling solar-thermal generating system, including column, mirror surface support and minute surface, mirror surface support and minute surface are dish, and radially offer the open slot of one sector, column is made up of upper pillar stand and lower pillar stand, and upper pillar stand is arranged on lower pillar stand by rotary flange, and the cross section of upper pillar stand is trapezoidal, upper pillar stand passes open slot, and mirror surface support is arranged in the rotating shaft at upper pillar stand top.
Mirror surface support is made up of truss and connecting rod, and truss is radially arranged, and connecting rod is circumferentially distributed for connecting adjacent two truss, does not has connecting rod between two of which adjacent truss, forms open slot, and the end of open slot is provided with bindiny mechanism.
Upper pillar stand is arranged on lower pillar stand by rotary flange, and rotary flange is provided with driving motor and transmission mechanism.
Being enclosed within bottom upper pillar stand in mounting seat, the mirror surface support back side is provided with linear electric motors, and the push rod front end hinge of linear electric motors is contained in mounting seat.
Go to the bottom as circular arc on upper pillar stand trapezoidal cross-section.
Beneficial effects of the present invention:
The cross section of upper pillar stand make into trapezoidal after, can effectively reduce need on minute surface fluting size, the quality of column also greatly reduces simultaneously, make transport and install the most convenient.
An attachment structure is set up at fluting, the tangential intensity of dish stand can be compensated, thus improve the intensity of whole dish stand, connecting elements and the total quality of dish stand can be greatly reduced under same design strength, also allow for manufacturing the component being prone to transport and installing in the dish stand structure simplified simultaneously, reduce installation cost.
Accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is the partial enlarged view of position VI in Fig. 1.
Fig. 3 is the top view of upper pillar stand.
Fig. 4 is the structural representation of dish stand.
Detailed description of the invention:
Such as Fig. 4, dish stand 1 is made up of truss 11 and connecting rod 12, and truss 11 is distributed in umbrella skeleton formula, and each truss 11 is truss structural, and is perpendicular to dish face.Between two adjacent truss 11, along dish face, connecting rod 12 circumferentially connects with multiple.Wherein have between two truss 11 and be not provided with connecting rod 12, material is thus formed a fan-shaped open slot 3, outermost end at open slot 3 arranges an attachment structure 4, attachment structure 4 is a frame structure, on the left of it, hinge is contained on the truss 11 of left side, have on the right side of attachment structure 4 and the structure of right side truss 11 linking, the present embodiment is use connecting hole and bolt to be attached.Minute surface 2 is to be had, by polylith, the parabola being spliced after the eyeglass of certain curvature is arranged on dish stand 1, and attachment structure 4 is also installed one piece of eyeglass.
After whole dish stand 1 is installed on column, form structure as shown in Figure 1, column is made up of upper pillar stand 5 and lower pillar stand 6, upper pillar stand 5 is arranged on lower pillar stand 6 by rotary flange 7, the cross section of upper pillar stand 5 is trapezoidal, trapezoidal upper bottom is circular arc, and upper pillar stand 5 is through open slot 3, and mirror surface support 1 is arranged in the rotating shaft at upper pillar stand 5 top.
Driving motor 8 and transmission mechanism are installed on rotary flange 7, drive motor 8 to deliver torque to rotary flange 7 by transmission mechanism and make it rotate..
Being enclosed within bottom upper pillar stand 5 in mounting seat 9, mirror surface support 1 back side is provided with linear electric motors 10, and the push rod front end hinge of linear electric motors 10 is contained in mounting seat 9.Linear electric motors 10 can realize the elevating movement of whole dish stand 1.
