Technical field
The utility model relates to a kind of bearing unit of the tracking axis for solar energy thermal-power-generating station.Tracking axis is for supporting the minute surface with relative sun adjustment solar energy thermal-power-generating station, especially parabolic trough type mirror and Fresnel minute surface.
Background technique
The traditional minute surface converged to by sunlight on adsorber is used in solar energy thermal-power-generating station.At this, minute surface follows the tracks of the sun usually, to obtain maximum radiation intensity all the time on adsorber.At this, minute surface is usually to have the narrowband versions of greater depth along North and South direction orientation.In so-called Fresnel minute surface power station, these minute surfaces orientation as follows, that is, make the adsorber at center be irradiated by multiple minute surface.As an alternative, in so-called parabolic trough type mirror power station, these minute surface channel-shaped ground archings, thus make each minute surface irradiate the adsorber be arranged in the focusing coil of groove of oneself.In these two kinds of structural types, minute surface is bearing on the tracking axis that stretches along the longitudinal direction usually respectively as follows, that is, make whole minute surface can in east-west direction surface thereof to follow the tracks of the sun.
Solar energy thermal-power-generating station is arranged on awfully hot Desert Area usually, because there has solar radiation strong especially.Assembly (especially the bearing structure of tracking axis and bearing) usually suffers the very strong load caused by wind, dust and drift sand under the typical environmental conditions of this correspondence, and therefore must resistance to land used design.In addition, because very high temperature and day and night temperature there will be the significant length change of different assembly usually, this length change must be considered again or it is compensated, to make movable parts be jammed, and keeping the tracking precision of minute surface.
By the known a kind of device for Fresnel solar energy collector of EP1754942B1, wherein, tracking axis is bearing in roller stand by three rollers in the mode that can rotate, and these rollers are to arrange around the mode of tracking axis circumference distribution.
Model utility content
Task of the present utility model is, a kind of bearing unit simple and durable especially for tracking axis is described.
According to the utility model, the bearing unit for the tracking axis at solar energy thermal-power-generating station comprises the housing with two shell body walls parallel to each other.In addition, bearing unit comprises two axis bodies, and these axis bodies in parallel with each other and perpendicular to shell body wall ground orientation, and these axis bodies are bearing in two shell body walls respectively.Therefore, each in two axis bodies defines the connection between two shell body walls.According to the utility model, in order to support tracking axis, each in two axis bodies has the slide bushing that ring-type surrounds corresponding axis body respectively.Therefore, tracking axis can accurately or at least approx be bearing on two slide bushings in the mode being parallel to two axis bodies substantially, that is, to make tracking axis can rotate around its spin axis.
In addition, in favourable structural scheme, slide bushing also causes tracking axis can along its axial direction relative to housing and axis body slippage when the length change caused by temperature.By this axial displaceability of tracking axis, effectively can prevent the axial load of bearing unit, or can effectively prevent tracking axis from clamping in bearing unit, may occur due to the shaft length change caused by temperature in the axle that both of these case supports at axial restraint.Therefore, assume responsibility for the function of floating bearing according to bearing unit of the present utility model, by this floating bearing, even if tracking axis also can be in the axial direction unstressed at the temperature of different or conversion support.
Here and hereinafter, be interpreted as canular object for term " slide bushing ", wherein, at least one surface (internal surface or outer surface) is formed by the material with the coefficient of sliding friction little especially.In scope of the present utility model, the plastics that this material can be such as sintered bronze or fill with slip medium, such as PTFE (teflon/" Teflon ").Therefore, use this slide bushing to reduce the friction of tracking axis and/or axis body, thus can especially easily make tracking axis rotate.Especially relative to using more complicated rolling bearing, slide bushing can realize the simple of bearing unit and the structure of low cost.In addition, by the durable structure using slide bushing to obtain bearing unit, this is because slide bushing is almost Maintenance free, especially supplemental lubrication need not be carried out with the regular time lag.In addition, slide bushing is used can to realize the simple assembling of bearing unit.
