Description
Technical field
The utility model belongs to the solar light-heat power-generation technical field, is specifically related to the double-layer combined self-balancing structure of a kind of line-focusing solar reflection frames.
Background technology
The solar energy thermal-power-generating technology is through concentrator solar energy collecting to be got up to be converted into heat energy, produces the generating of high temperature and high pressure steam driving steam turbine then.
The solar energy thermal-power-generating technology is distinguished from the type of focusing and can be divided into two kinds of line focus and point focusing.Wherein the hot generation technology of line-focusing solar optically focused is a kind of common form of present solar energy thermal-power-generating; The Jing Chang that constitutes through polygonal mirror becomes the wire hot spot with solar-energy collecting; Utilize receiver that luminous energy is converted into heat energy then, through heat-conducting fluid with heat absorption and be delivered to heat exchanger.The heat of heat-conducting fluid is used to heat water and generates steam in heat exchanger, and then utilizes steam driving steam turbine acting generating.
In whole line-focusing solar thermal electric generator, the condenser field is the most key assembly.Mirror field light gathering efficiency is directly connected to the transformation efficiency of final luminous energy to electric energy.Because limited for the requirement and the receiver width of optically focused ratio in the solar energy thermal-power-generating technology, therefore the width to the wire hot spot has proposed certain requirement.In order to obtain the narrower focal beam spot of width, the most frequently used solution is to use the speculum that has small radian to replace level crossing, but owing to the machining accuracy of differential of the arc speculum is difficult to guarantee, thereby cause the rising of spotlight effect weakening and processing cost.In addition,,, thereby increase the live load of drive motors, increase the operating cost of solar-energy light collector if device off-centre seriously can cause moment of torsion to increase because the weight of speculum and support is bigger.Therefore, the design of support also will be considered integrally-built distribution of weight problem.
The utility model content
In order to overcome the shortcoming of above-mentioned prior art, the purpose of the utility model is to provide a kind of line-focusing solar reflection frames double-layer combined self-balancing structure, has solved the problem of big cost height of differential of the arc speculum difficulty of processing and rotating eccentricity.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
The double-layer combined self-balancing structure of a kind of line-focusing solar reflection frames; Comprise the main shaft 1 that links to each other with follow-up mechanism; Main shaft 1 is horizontally placed on supporting traverse 2 tops, and supporting traverse 2 has a plurality of and is parallel to each other, and all is respectively arranged with a vertical adjustable fulcrum 3 in the two ends and the centre of each supporting traverse 2; Each adjustable fulcrum 3 all flexibly connects with corresponding speculum base 4, so that speculum base 4 adjustable height.
Said main shaft 1 is a metal circular tube, and is vertical with supporting traverse 2.
Said adjustable fulcrum 3 links to each other with speculum base 4 through strip hole 7 for having the support of strip hole 7, and adjustable fulcrum 3 with on the end that supporting traverse 2 is connected is not provided with fine adjustment screw 6.
The beneficial effect of the utility model is: regulate the radian of level crossing based on the principle of mechanical cold deformation, and can fast and low-cost ground preparation differential of the arc minute surface.With existing hot bending processing globoidal mirror compared with techniques, owing to can directly use the common plane mirror, so processing cost significantly reduces, and for differential of the arc mirror, also greatly reduces the complexity of processing technology and improved the accuracy of speculum arc.Formed double-layer combined self-balancing structure through supporting traverse and speculum are distributed in the main shaft both sides, itself had both born the supporting role of speculum the base portion of support lower floor, also played the eccentric phenomena of counterweight effect balance speculum simultaneously.Can realize zero final off-centre through regulating parameters such as support height; Significantly reduced the requirement of system for drive motors and reductor; Significantly reduce the manufacturing cost and the operating energy consumption of Fresnel formula heliostat field, have great significance for final reduction solar energy thermal-power-generating cost.

Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structure chart of the adjustable fulcrum 3 of the utility model.
The specific embodiment
Specify the embodiment of the utility model below in conjunction with accompanying drawing and embodiment.
As depicted in figs. 1 and 2, the utility model is the double-layer combined self-balancing structure of a kind of line-focusing solar reflection frames, comprises the main shaft 1 that links to each other with follow-up mechanism, and main shaft 1 is a metal circular tube, plays a part to carry and rotating shaft.Main shaft 1 is horizontally placed on supporting traverse 2 tops, and supporting traverse 2 is made up of with the channel-section steel that the speculum width equates many length of parallel installation on steel pipe, has two kinds of effects of support structure and constitutional balance, and supporting traverse 2 has a plurality of and is parallel to each other; Two ends and centre at each supporting traverse 2 all are respectively arranged with a vertical adjustable fulcrum 3.
As shown in Figure 3, adjustable fulcrum 3 is a basic structure with the channel-section steel, and strip hole 7 is opened in the side, and fine adjustment screw 6 is installed in the top tapping, and the bottom is connected with supporting traverse 2, and speculum base 4 is an angle aluminium, passes strip hole 7 through bolt 8 and is fixed on the adjustable fulcrum 3.
Parts such as above-mentioned supporting traverse, adjustable fulcrum, speculum base have been formed the picture frame structure; Because most weight of picture frame concentrate on speculum and supporting traverse; Can control the arm of force of speculum through the support height of adjustment adjustable fulcrum to spindle axis; Thereby the moment between supporting traverse and the speculum is offset fully, realized the self-balancing of system.
When the mounting bracket device, can adjust the difference in height between two side rearview mirror bases and the middle base, then plane mirror 5 is sticked together through silica gel and base according to required minute surface radian.Find that focusing effect is not ideal enough if solidify the back fully, can also utilize fine adjustment screw that the minute surface radian is carried out the secondary adjustment then, to reach best spotlight effect through unclamping the set bolt at strip hole position at silica gel.
Utilize the holder device of the utility model to connect plane mirror 5, holder device both played a supportive role, and also can carry out the differential of the arc to speculum through the adjustable fulcrum of regulating holder device simultaneously and regulate, and follow the tracks of daylight by the tracing system driven in rotation.
