Embodiment
As shown in Figure 1, provide usually with the 10 solar electrical energy generation towers that represent.Solar electrical energy generation tower 10 comprises the array of heliostat 12, and it is configured to the solar radiation of collecting tower 14 reflection bumps.Thereby collecting tower 14 contains by the solar radiation heating of reflection and for the hot fluid (not included) 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 device 16 of the fixed position in the ground and the heliostat assembly 18 that is supported by base device.
Base device 16 comprises the pylon 20 that is fixed in the ground and the position of especially supporting heliostat assembly 18 and the interface arrangement 22 that is supported by pylon.Base device 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 heliostat assembly 18.
Heliostat assembly 18 comprises the torque tube 28 that supports a plurality of sway braces 30.Some sway braces 30 support the catoptron 32 of the reflecting surface that consists of heliostat assembly 18.Also be provided for the brace 38 that supports.Two braces 38 and a sway brace 30 consist of triangular structure together, to provide support.Sway brace 30, catoptron 32 and brace 38 consist of mirror assembly.
As shown in Figure 3, reflection unit 600 comprises common mirror assemblies with 601 expressions, and torque tube 28.(should be understood that in Fig. 3 catoptron 32 is shown transparent, in order to help to illustrate the element under it.) each sway brace 30 consists of the truss 604 of mirror assembly 601 with two braces 38 and center bearing bracket 602.Center bearing bracket 602 withstands torque tube 28, thereby strengthens truss 604, and is used for simultaneously supporting torque tube, thereby is convenient to its motion is transferred to catoptron 32.
As shown in Figure 4, torque tube 28 is the hollow tube at both ends open.It can be made by any suitable material, and has enough physical strengths, transfers to mirror assembly 601 with the mechanical energy of the form that will rotatablely move, and is not out of shape and can not show, and namely reaches this distortion and will adversely affect the degree of its work.
Provide sway brace 30 with along its width supporting reflex mirror 32.Usually, provide several (for example, three) sway braces 30 spaced in parallel to each other for each catoptron 32.Each sway brace 30 can be by any suitable material, and for example iron, aluminium or the synthetic material such as plastics are made.It can use any suitable method, presses or extrudes and make such as rolling, lock.The length of sway brace 30 can equal the length of catoptron or less than its length.
From for example finding out Fig. 5 A, each sway brace 30 forms the slender member with common Ω shape profile, and it has roof 608 and substantially vertically from its two sidewalls 610 that stretch out downwards.Roof 608 is generally smooth, in order to be suitable for catoptron 32 attached to itly, and form have the top passageway 612 (what see is inside indenture) of extending along the length of sway brace 30 in Fig. 5 A.Turn over end 614 on the lowermost end part termination of each sidewall 610, turn over end 614 on each and limit wing passage 616.The top of each sidewall 610 is forming outwardly directed bossing 618 near it to the zone of the connection of roof 608.For example when comparing with the passage of equal length and/or weight or L shaped profile, the above-mentioned section shape of sway brace 30 has increased its crooked moments of inertia.
Shown in Fig. 5 B, each sidewall 610 comprises brace mounting hole 620a, described brace mounting hole 620a can with center bearing bracket mounting hole 620b equi-spaced apart.Among brace mounting hole 620a and the center bearing bracket mounting hole 620b each all with in another sidewall 610 with it corresponding aperture of relative formation related.Should be understood that brace mounting hole 620a can be asymmetrically formed along the length of sway brace 30, wherein compare one group of end that forms more close sway brace in the brace mounting hole with another group brace mounting hole of the other end that is formed at sway brace.
In addition, other hole 620c can be formed in the support bar 30.When using or dispose mirror assembly 601, these holes are without any function and usage, but it is formed to be convenient to the manufacturing of mirror assembly 601, for example with hook or other similar supporting member it is hung up when making or dispose mirror assembly or its parts by being convenient to.
When reflection unit 600 all assembled, sway brace 30 had curve shape, for example parabolic shape or nearly parabolic shape.This can have by manufacturing the sway brace 30 of required form, or by to provide support arm be upright and its bending is realized during the reflection unit 600 in assembling.Under latter instance, required form is the length by regulate brace 28 during assembling truss 604 for example, or realize by very accurately forming brace mounting hole 620a, wherein provides accurate tightening member so that brace is fastened on the sway brace 30.
Bonding agent is put on the roof 608 of sway brace 30, in order to help catoptron attached to it.Bonding agent can be any suitable material or adhesive strip.In the situation of bonding agent, can use single adhesive strip along the total length of sway brace 30, or can use a plurality of adhesive strips along its total length.For example, bonding agent can be contact adhesive, such as by 3M company with trade name " VHB
TM" contact adhesive that provides.Downside with catoptron is attached to bonding agent subsequently.
As shown in Figure 6, each brace 38 forms the slender member of (hollow structure part) profile that has rectangle HHS.Brace 38 can be by extruding or forming by any other suitable method.The top 622 of each brace 38 can be circular.In two side plates that be arranged in parallel 624 of brace 38 each all forms the sway brace mounting hole 626 with close top 622, and the center bearing bracket mounting hole 628 of the bottom 630 of close brace.In the hole 626,628 each all forms with respect to the corresponding aperture that forms in the opposite side plate 624.In addition, another hole 632 can be formed in the brace 38.When using or dispose mirror assembly 601, these holes are without any function and usage, but it is formed to be convenient to the manufacturing of mirror assembly 601, for example with hook or other similar supporting member it is hung up when making or dispose mirror assembly or its parts by being convenient to.
As mentioned above, provide center bearing bracket 602 in order to strengthen truss 604, and support torque tube 28 (in other words, it is convenient to by the torque tube sub-truss).Shown in Fig. 7 A and Fig. 7 B, center bearing bracket 602 has the shape of common triangle, and comprises the jaw 634 of common circle, and described jaw 634 is configured to clamping torque tube 28.Center bearing bracket 602 comprises the identical 636a of first and second portion 636b (hereinafter, when general designation first and second portion, it will be represented by Reference numeral 636), each center bearing bracket 602 is arranged, thereby so that its ° be shifted by relative another center bearing bracket Rotate 180.Upside web member 642 and downside web member 644 that each part 636 comprises front 638, back 640 and is across between the front and back and connects, wherein upside web member and downside web member are separated by gap 646.
