3Parallel with the optically focused light XY of parabolic reflector 33; Its beneficial effect is, the radiation intensity of the upper each point of optically focused light XY is identical, and when the light-receiving area of concentrator 31 and light concentrating times were enough large, each point had very high radiation intensity on the optically focused light XY, is enough to reach at short notice the fusion temperature of Desert Sand; When parabolic reflector 33 under the driving of scan module 19 during along scan track 18 horizontal movement, walking mechanism 12 is halted state, optically focused light XY moves with parabolic reflector 33, the scanned sand of optically focused light XY melts by supercooling, form hard stone matter rectangle hardened layer, reach the purpose of sclerosis desert surface.Its beneficial effect is: by optically focused light XY horizontal Shamian Island 11 scannings are had higher efficient than some optically focused, motion is simplified more; When even sun altitude φ is very little, also can form dimensionally stable and the optically focused light XY of relative fixed-focus position is arranged, greatly prolonged the working time has been used in the focusing of the sun.The instant radiation intensity of the sun that the rate travel of parabolic reflector 33 and intensity of solar radiation sensor 54 detect is proportional, the resulting emittance of area of optically focused light XY scanned horizontal Shamian Island 11 within the unit interval is consistent, its beneficial effect is: can make the fusing sclerosis of horizontal Shamian Island 11 more even, better effects if; Because the emittance of the sun is constantly changing, walking mechanism 12 is in halted state, only driving parabolic reflector 33, to carry out the energy consumption of scan module 19 of variable motion less, and the scanning motion process is sensitiveer, and the fusing hardening region that parabolic reflector 33 forms is rectangle.Parabolic reflector 33 is horizontal Shamian Island along below in the stroke of scan track 18 horizontal movements, without any obstruction, its beneficial effect is: walking mechanism 12 when walking, left row travelling wheel band 15 and right side road wheel band 16 can not roll the zone of having hardened, and make hardening effect better.
Such as Fig. 2, shown in Figure 4, the offset solar energy direct line optically focused desert surface hardening system that the utility model provides, the direct of travel of walking mechanism 12 is North and South direction, i.e. the direction of MN shown in the figure; Advance according to North and South direction, its beneficial effect is that the azimuth maximum rotation amount of horizontal warp-wise speculum 32 is minimum, and the specular cross section of horizontal warp-wise speculum 32 is also minimum, is conducive to make and reduce cost; Left side movable motor 13 drives left row travelling wheel band 15, and right side movable motor 14 drives right side road wheel band 16; By the control of computer 51, when left row travelling wheel band 15 was identical with direction with right side road wheel band 16 velocities of rotation, walking mechanism 12 was travelled along rectilinear direction; When left row travelling wheel band 15 and right side road wheel band 16 velocities of rotation not simultaneously, walking mechanism 12 is travelled along direction of a curve, thereby realizes turning function.
As shown in Figure 6, shading speculum 34 moves along the vertical direction, can be with the parallel rays from the horizontal broadwise speculum 35 of horizontal warp-wise speculum 32 directives, again reflex to horizontal warp-wise speculum 32, reflex to concentrator 31 by horizontal warp-wise speculum 32 again, and return along former propagation path, realize opening and closing control the radiation of optically focused light XY, simultaneously also make things convenient for examination and maintenance, prevent that high-intensity radiation from causing unnecessary damage and fracture.
Such as Fig. 2, Fig. 4, shown in Figure 7, the method for curing of the offset solar energy direct line optically focused desert surface hardening system that the utility model provides, comprise following procedure and step: when starting working, step a is for starting sun-generated electric power, namely solar radiation reaches certain value by day, when the power that produces on the solar module 21 can satisfy the electricity consumption needs, the unstable voltage of solar module 21 inputs is output as galvanic current by DC-DC DC voltage-stabilizing module 25 and presses, for whole system; Step b prevents that for closing shading speculum 34 high-intensity radiation from causing unnecessary damage and fracture, does not carry out desert surface and hardens; Step c is under the control of computer 51, start the sun program of following the tracks of, make the central axis SO of concentrator 31 " point to the sun, horizontal warp-wise speculum 32 turns to the position that optically focused light can be formed optically focused light XY by horizontal broadwise speculum 35 and parabolic reflector 33; Steps d makes walking mechanism 12 drive to assigned address, and is adjusted into north and south MN direction; Step e makes walking mechanism 12 be in halted state; Step f is that parabolic reflector 33 moves to starting point X
1Y
1Step g is for opening shading speculum 34, fusing sclerosis Shamian Island, parabolic reflector 33 levels move to another boundary point, and stop after arriving boundary point, form the scanning hardening region of rectangle, the translational speed of parabolic reflector 33 is directly proportional with the instant intensity of solar radiation that detects; Step h is for closing shading speculum 34, step I is that walking mechanism 12 is travelled and stopped after the L+ △ S distance, and wherein L represents the length of optically focused light XY, △ S〉0, △ S is the gap for the scanning hardening region of two adjacent rectangle, prevents from owing to expanding with heat and contract with cold adjacent hardened layer being damaged; Step j judges whether to work on, if be yes, then continues to repeat from step g; If be no, then execution in step k closes and follows the tracks of sun program, and beam condensing unit resets; Step p is for closing sun-generated electric power, and then shutdown system quits work.Its beneficial effect is: under the control of computer 51, optically focused light XY scanning forms several rectangle sclerosis blocks with certain intervals, a lot of sclerosis block continuous arrangements just can cover large-area desert surface, thereby realize the purpose to the large area region desert surface hardening; In and the desert Environment that conditions of transportation is inconvenient abominable in natural conditions, computer 51 can be by programme-control, does not adopt manually-operated and adopts unmanned auto-controll operation, fixes the sand cost thereby further reduced, and has improved the practicality of technical approach.
Azimuth, elevation angle are the terms that solar energy tracking utilizes industry.
