Detailed Description
The invention will be further illustrated with reference to specific examples.
A single-tower multi-hood solar energy collecting hood adjusting device comprises a movable ring 1, a fixed ring 2, a synchronous hydraulic motor 3, a fixed bolt 4, a reflector 5, a hollow strut 6, a collecting hood 7 and a detector 8; the outside of the hollow pillar 6 is sleeved with a fixed ring 2 and a movable ring 1, the fixed ring 2 is arranged below, the movable ring 1 is arranged above, and a plurality of synchronous hydraulic motors 3 are arranged between the movable ring 1 and the fixed ring 2; the hollow support column 6 passes through the collecting cover 7, and the lower end of the collecting cover 7 is arranged on the movable ring 1; inside the hollow column 6 there is a mirror 5 and a detector 8.
The collecting hood 7 has an outwardly protruding circular arc outer surface, and the collecting hood 7 has openings at the upper and lower sides to allow the hollow struts 6 to pass through.
The fixed ring 2 is a hollow cylindrical ring, the inner diameter of the cylindrical ring is larger than the outer diameter of the hollow support column 6, and the wall thickness of the cylindrical ring is not smaller than the diameter of the base of the synchronous hydraulic motor 3.
The fixing ring 2 is fastened to the hollow support 6 by means of fastening bolts 4, which serve to roughly fix the position of the collecting hood on the hollow support.
The fixed ring 2 is uniformly fixed with a plurality of synchronous hydraulic motors 3 at intervals, and uniformly controls the up-down telescopic heights of the synchronous hydraulic motors 3, and the adjustable movable ring has the main effects of accurately adjusting the height of the movable ring 1, and the adjusting precision is above millimeter level.
The reflector 5 is fixed on the inner wall of the hollow pillar 6 in the collecting cover 7.
The reflector 5 is obliquely fixed, the reflecting surface of the reflector 5 faces downwards, and a light hole is formed in the wall of the hollow support 6 at the reflector 5.
The detector 8 is positioned at the bottom end inside the hollow support 6, the detection surface of the detector 8 faces upwards, and the detector can be taken out after the correction of the position of the collecting cover is completed, and the main function of the detector is to determine the position of the light reflected by the reflector at the bottom of the hollow support.
As shown in fig. 2, the detector 8 will reflect the specific location of the spot, but the emission spot of each mirror 5 should be exactly theoretically designed. If the light spot a is a theoretical light spot and the light spot B is a actually detected light spot position, then the synchronous hydraulic motor 3 should be adjusted at this time so that the converging direction and the converging position of the light rays are emitted to change, thereby changing the light spot position. On the hollow pillar 6, there are several groups of collecting cover 7, reflector 5, movable ring 1 and fixed ring 2, if the spot position is not in the theoretical position, the light collected by the collecting cover 7 on the upper layer will fall on the back of the reflector 5 on the lower layer, resulting in light waste and overheat of the reflector 5.
By mounting the securing ring 2, the position on the hollow struts 6 of the collecting hood 7 can be roughly determined. The detector 8 at the bottom end of the hollow pillar 6 can determine the spot position at this time, and if the spot position is inconsistent with the theoretical spot position, the synchronous hydraulic motor 3 is adjusted so that the movable ring 1 moves up or down. The collection hood 7 is supported on the movable ring 1, and thus moves up and down. The synchronous hydraulic motor 3 is adjusted a plurality of times by comparing the positions of the light spots on the detector 8 until the light spots on the detector 8 fall at the theoretical positions.
All collecting cups 7 on the hollow struts 6 are corrected in the above-described manner so that all spots fall in the theoretical position. After all the collecting hoods 7 are corrected, the detector 8 is taken out, and the single-tower multi-hood solar collector can work normally. At intervals, correction is performed once.
The device is simple and effective, can solve the problems that the sunlight converging light is not fallen on the reflector 5 due to assembly errors and inconsistent solar incidence heights, and can indirectly solve the problems that the deflection amplitude of the reflector 5 is limited and the converging light beam cannot be directly reflected to the base of the hollow strut 6.
The present invention is not limited to the preferred embodiments, and any simple modification, equivalent replacement, and improvement made to the above embodiments by those skilled in the art without departing from the technical scope of the present invention, will fall within the scope of the present invention.
