Embodiment
As shown in Figure 1, provide usually with the 10 central tower-type electricity generation stations that represent.Central authorities' tower-type electricity generation station 10 comprises the array of heliostat 12, and it is configured to the solar radiation of collecting tower 14 reflection shocks.Thereby collecting tower 14 contains by the solar radiation heating of reflection and for the hot fluid (not shown) that electric power is provided to the power house.The power house can be for example hydropower, and in this case, the hot fluid of heating is used for making water overheated, and these water are subsequently by turbine expansion, to obtain the useful energy and to generate electricity.
As shown in Figure 2, each heliostat 12 includes and is configured to heliostat is supported on the base unit 16 of the fixed position in ground and the mirror assembly 18 that is supported by base unit.
Base unit 16 comprises and will be fixed on the interface arrangement 22 of pylon 20 and the especially position of supporting reflex mirror assembly 18 in ground.Base unit also comprises position angle driver 24 and elevation angle driver 26, and it controls respectively position angle and the elevation angle of the reflecting surface of mirror assembly 18.
As shown in Fig. 3 A to 3C, pylon 20 comprises the tubulose vertical tube 100 of longitudinal extension, and this vertical tube can be hollow.Vertical tube 100 can be made by galvanized steel or any other suitable material.Pylon comprise its near-end 104 places usually with the driving bracing or strutting arrangements of 102 expressions and near the far-end 108 of vertical tube 100 usually with the anti-rotation devices of 106 expressions.In addition, as shown in Figure 3 C, pylon 20 can comprise the conical lid 110 at far-end 108 places.(should be appreciated that although Fig. 3 C shows cover 110 the similar pylon 20 of pylon with having shown in Fig. 3 B, the pylon shown in Fig. 3 A also can be provided with this lid).
As shown in Fig. 4 A and 4B, drive bracing or strutting arrangement 102 and comprise some (as six) socket 112, it is configured to conveniently hold the tightening member (not shown) that is connected to driver as above.Socket 102 can be evenly distributed on around the circumference of vertical tube 100.Each socket 112 is limited by the circular side wall 114 that is formed at the longitudinal extension in vertical tube 100 and pedestal 116.Pedestal 116 can have any suitable shape.For example, as shown in Fig. 4 A, pedestal 116 can be flat, and is generally perpendicular to sidewall, and perhaps as shown in Figure 4 B, pedestal can be circle.Annular flange 118 limits the coboundary of each socket 112.Flange 118 inwardly stretches out the top of each socket 112, in order to provide sufficient covering for it.Through hole 120 is arranged in the flange 118 of each socket 112 tops.
According to an example, as shown in Figure 3A, anti-rotation device 106 can comprise some (as four) extrude angle 122 of the side that is connected to vertical tube 100.Angle steel 122 (for example about 45 degree) at a certain angle is connected to vertical tube 100.Can provide in pairs the angle steel 122(that connects toward each other with the diagonal angle namely, when observing from single direction, these angle steel become the diagonal angle).Angle steel 122 can be by any suitable material, and for example the material identical with vertical tube 100 made, and can be connected with vertical tube as welding by any suitable mode.Such anti-rotation device 106 is applicable to the situation that pylon 20 will be arranged in concrete.
According to another example, as shown in Fig. 3 B and 3C, anti-rotation device 106 can comprise that this vertical tube can connect by any suitable mode such as welding from the radially-protruding vertical fin 124 of vertical tube 100.Fin 124 is on radial height at its far-end 126 to be increased from being roughly zero, and reaches whole radial height (that is, to the relatively short axial distance of its near-end), thereby forms wedge shape part 128.The axial length of wedge shape part 128 can be equal to or greater than the radial height of fin 124.This shape is conducive to by the axial resistance that reduces fin 124, pylon 20 be inserted ground.Such anti-rotation device 106 is applicable to the situation that pylon 20 will be arranged in ground.
Be clear that from Fig. 5, wedge shape part 128 can be shaped as and the main longitudinal member 130 of fin 124 element independently.Main longitudinal member 130 can be shaped as roughly V-shaped profile, and it comprises two panels 132 that connect along its long limit 134.
One or more fins 124 can be shaped as has the through hole 136 that for example forms in wedge shape part 128.When using or dispose heliostat 12, these hole 136 nonfunctional purposes, but it is formed to be convenient to the manufacturing of pylon 20, for example by with hook or other similar supporting member, it being hung up during the manufacturing of pylon.
Although shown pylon 20 comprises three fins 124, also can provide the fin of any suitable quantity.
Be clear that from Fig. 5, lid 110 can have round tip 138, and is shaped as and has through hole 140.In the use procedure of pylon 20, any effect can not played in hole 140, and is the artefact in manufacture process, and wherein this hole is conducive to the release of gas, and this gas is the accessory substance of galvanizing process.For same purpose, one or more additional holes 146 can be arranged on and cover on 110 side.Hole 140,146 should be as much as possible little, so that for example when disposing heliostat 12, during pylon is inserted ground, prevents that sand grains or other material from entering the inside of pylon 20 through this hole.Lid 110 can be shaped as at its most proximal end place has relatively short cylindrical part 142.Round tip 138 can be shaped as at its distal-most end place has flat part 144, and through hole 140 is formed in this flat part.
Be formed in most advanced and sophisticated 138 center (that is, at the distal-most end place of pylon 20) although hole 140 is shown, this hole also can be formed in its another position, for example, and on the side of lid 110.Can select the center in the hole 140 on most advanced and sophisticated 138, so that make.
Those skilled in the art under the utility model is easy to understand, in the situation that do not break away from the utility model (necessary revision) scope, can carry out multiple variation, change and modification to it in addition.
