Description

A kind of hail suppression type heliostat
Technical field
The utility model relates to a kind of heliostat for Solar use.
Background technology
Heliostat is the beam condensing unit of tower type solar opto-thermal system, and heliostat reflecting surface follows the tracks of the sun, is reflected by sunshine and gathers fixed target.Current heliostat reflecting surface generally adopts silvered glass catoptron, and silvered glass catoptron has the advantages such as reflectivity is high, the life-span is long.Heliostat reflecting surface is generally assembled by the glass reflector in multiple unit mirror, and the glass reflector in unit mirror is become the differential of the arc face of needs by sheet glass catoptron by cold drawn and formed, and keep its differential of the arc shape by unit mirror support.But the glass reflector of heliostat unit mirror is hard brittle material, easily damaged under compared with the impact of heavy hail, heliostat can not be worked.
Some heliostats, in order to improve anti-ice hail type energy, certainly mainly improve the anti-ice hail type energy of glass reflector, arrange one deck tempered glass, be provided with doubling layer between silvered mirror and tempered glass in silvered glass mirror back surface.Although tempered glass and doubling layer improve the intensity of reflector for heliostat, shortcoming is the significantly raising bringing catoptron cost, also brings significantly improving of heliostat cost thereupon.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of hail suppression type heliostat of relatively low cost.
The technical scheme that the utility model technical solution problem adopts is:
Be provided with on heliostat pillar top and add by pitching rotating mechanism the double-axis tracking transmission case that horizontal rotary mechanism combines, heliostat girder is separately installed with in the both sides of the pitching rotating mechanism of double-axis tracking transmission case, every side heliostat girder is provided with an inner plane truss and an outerplanar truss, and inner plane truss is parallel to each other with outerplanar truss and vertical with heliostat girder; Inner plane truss on the heliostat girder of every side and outerplanar truss are provided with two outer crossbeams and an interior crossbeam, and outer crossbeam is vertical with outerplanar truss with inner plane truss with interior crossbeam; Outer crossbeam links with inner plane truss and outerplanar truss simultaneously, and in same, crossbeam also links with inner plane truss and outerplanar truss simultaneously; Two outer crossbeams and interior crossbeam are along the length equidistant placement of inner plane truss and outerplanar truss, and interior crossbeam is positioned at centre, and two outer crossbeams lay respectively at both sides.More than form the main supporting structure of heliostat.Two outer crossbeams and an interior crossbeam are provided with multiple unit mirror; The glass reflector of all unit mirrors forms heliostat reflecting surface.Heliostat reflecting surface is open type or semi-open type structure.On one's own time, heliostat girder around the horizontal rotational shaft of pitching rotating mechanism, can make heliostat reflecting surface back-off.In the heliostat structure at the glass reflector back side, be parallel to heliostat reflecting surface and anti-hail net is installed.Leave gap between anti-hail net and glass reflector, prevent anti-hail net to be subject to producing elastic deformation when hail impacts and impact glass reflector.In the heliostat non-working time, heliostat reflecting surface back-off, at this moment anti-hail net is positioned at the top of glass reflector, and when there being hail to land, anti-hail net can block hail glass reflector being caused to damage.
Concrete solution has two kinds:
One, anti-hail net is arranged on unit mirror support:
The back side of the glass reflector of described unit mirror is bonded with glass reflector support member; Described glass reflector is positioned at the top of unit mirror support, and upward, the back side of glass reflector is linked by glass reflector support member and unit mirror support the reflecting surface of glass reflector; Anti-hail net can be parallel to the bottom that glass reflector is fixed on unit mirror support.
Two, anti-hail net is arranged on heliostat post main supporting structure:
On two outer crossbeams that anti-hail net is fixed on the heliostat main supporting structure at heliostat reflecting surface back and an interior crossbeam.
Anti-hail net is made up of wire gauze and metal framework, and wire gauze is linked into an integrated entity by welding and metal framework.
The width of mesh of wire gauze should be determined by following principle: can cause the hail of damage should not by anti-hail net to glass reflector.
The utility model just in heliostat unit mirror the glass reflector back side heliostat structure on increase one deck anti-hail net, the cost of anti-hail net is lower, increases anti-hail net and can not significantly increase heliostat cost.
