Description
Technical field
The utility model belongs to the solar energy heat utilization technology in new forms of energy or renewable energy source domain, as take the key equipment of the groove type solar heat collector that thermal-collecting tube is rotating shaft, by solar ray collecting to thermal-collecting tube.
Background technology
The groove type solar heat collector using in solar energy thermal-power-generating field, by grooved (parabola) condenser, sunshine reflection to be gathered on thermal-collecting tube, medium is heated, produce and deliver to steam turbine generator compared with the steam of high parameter, realize solar light-heat power-generation and heat supply.Steam parameter (temperature and pressure) is higher, and conversion efficiency of thermoelectric is just higher.
The generating occurring on Vehicles Collected from Market groove type solar heat collector, is mainly comprised of grooved (parabola) condenser, thermal-collecting tube, thermal-collecting tube (joint area) bracing frame, import and export medium guiding tube, top (low level) support, end (high position) support, bearing block and tracking (sun) device institute.Its grooved (parabola) condenser is generally heavy sheet glass speculum or composite materials, level is installed, because considering center of gravity problem, following the tracks of (sun) rotating shaft does not overlap with thermal-collecting tube (focal axis line), this is kept in motion condenser thermal-collecting tube in following the tracks of sun process, thermal-collecting tube must could be connected with external agency pipeline by soft guiding tube or with the guiding tube of active joint, so causing bearing pressure medium can not be too high, affect conversion efficiency of thermoelectric (unless adopting heat-storing device to carry out secondary heat exchange).In addition, because being subject to involving of external connecting pipe road, need to consume larger tracking power.This just causes take the appearance of the groove type solar heat collector that thermal-collecting tube is rotating shaft, and thermal-collecting tube is positioned on focal axis line by middle bearing bracket and end axis bearing, and these bearing blocks also follow the tracks of the rotating shaft of solar time.The condenser size of making of heavy sheet glass speculum is large, frangible, is not easy to transportation and on-the-spot installation.The condenser of making of composite is also because volume transports greatly difficulty.
Above background technology can be with reference to the architectural feature of current trough type solar power generation technology, groove type solar heat collector, and patent documentation: a kind of groove type solar heat collector ZL201120049309.1 and 201110047054.X.
Summary of the invention
Current groove type solar heat collector need to solve that condenser focal axis line (thermal-collecting tube) in following the tracks of sun process does not overlap with rotating shaft and factory manufactures, is not easy to the problems such as transportation and scene installation.
The condenser that the thermal-collecting tube of take is rotating shaft is a kind of parabolic reflector condenser, mainly left reflection minor (1), right reflection mirror (2), intermediate truss (3), top plate-girder (4) and end plate-girder (5), is consisted of.Each is comprised of left reflection minor (1) and right reflection mirror (2) parabolic muscle, the side truss that is connected parabolic muscle, parabola substrate and mirror surface, between left and right speculum, by parabolic muscle end flange sheet, fix, left and right speculum fixes with top plate-girder (4) and end plate-girder (5) respectively by the parabolic muscle at both ends.Intermediate truss (3) is upper with pedestal base (31), carrys out support set heat pipe (joint area), thereby thermal-collecting tube is positioned on focal axis line (OA) in order to fixing middle bearing bracket.Condenser can tilt to install or level installation according to region angle of latitude on the whole.For left and right speculum, parabolic muscle is key element, and the parabolic shape that parabolic muscle has has determined the shape of parabola substrate.It is not that very strong material is made that parabola substrate generally adopts rigidity, abuts against on parabolic muscle, with its setting.And reflectance coating or speculum are close to parabola substrate surface formation mirror surface, its reflectivity has determined the reflecting condensation efficiency of condenser.
Intermediate truss (3) bottom is inserted in one by one between left and right speculum parabolic muscle end flange sheet and fixes with a plurality of flange plates, and intermediate truss (3) both ends fix with beginning, end plate-girder respectively with flange plate.The effect of intermediate truss (3) is to strengthen condenser rigidity, balancing axial thrust and support set Heat pipe joint place weight.In order to strengthen the rigidity at pedestal base place, can increase diagonal brace in both sides, rafter foot is fixed on corresponding parabolic muscle.Do not worry that intermediate truss (3) can shut out the light, because its shadow region in thermal-collecting tube completely.
Top plate-girder (4) and end plate-girder (5) have the centre bore that allows the hollow shaft of end axis bearing pass in centre position place, and are connected with beginning, the end support of heat collector respectively by end axis bearing.Top plate-girder (4) is convenient to the connection of sun tracker with connection pin-and-hole.If tilt to install, top plate-girder (4) is connected by end axis bearing with high-level bracket separately with low level support, end plate-girder (5), makes condenser opening towards the sun.Condenser not only will bear downward gravity, also will bear axially (along burnt axis direction) thrust, the weight of whole condenser and axial thrust by beginning, end plate-girder is passed to beginning, end support by end axis bearing respectively.For the position being connected with intermediate truss (3) upper steel tube end flange plate, because being not easy to punching, can arrange one with the Connection Block of flange plate, effectively solve connectivity problem.
Accompanying drawing explanation
Fig. 1 take condenser that thermal-collecting tube is rotating shaft to be split as the relative position relation figure of 5 large parts.In figure: 1-left reflection minor, 2-right reflection mirror, 3-intermediate truss, 31-pedestal base, 4-top plate-girder, 5-end plate-girder, OA-focal axis line.
Fig. 2 be take the assembly drawing of the condenser that thermal-collecting tube is rotating shaft, and the mark implication in figure is identical with Fig. 1.
The specific embodiment
Left reflection minor (1) and right reflection mirror (2): left and right mirror structure is symmetrical.The key element of these two parts is parabolic muscle.According to the focal length of the required selection of condenser and width design parabolic type, with digital-code laser cutting technique, steel plate is processed into parabolic muscle after drawing electronic drawing.Along the parallel number of packaged parabolic of the length direction muscle (this programme is 13) of condenser, the suitable position of every parabolic muscle is cut with circular hole, with steel pipe, strings together and firm welding, and the diagonal brace of simultaneously burn-oning, forms side truss.Side truss both ends and beginning, end plate-girder are fixed.On parabolic muscle, fixedly sheet metal or PVC plastic plate form parabola substrate, then at parabola substrate surface, stick reflectance coating and form mirror surface.Left and right condenser binding site is fixed with threaded fastener by the flange plate of parabolic muscle end.
