Embodiment
As shown in Figure 1, this solar panel is evaded sand and dust, the sleet method comprises support column 18, main cross bar 10 grades are formed a space structure system, polylith solar panel a (is illustrated as 3 solar panels, also can be 2 or 20,200 ...) before and after be successively set in this space structure system of without hindrance block material, be provided with hinged component 16 and be connected (hinged component 16 is referring to Fig. 8--11) with bearing b hinge on each solar panel a, making it each solar panel a, to have with hinged component 16 be the center of circle, before daylighting face 21, the back or on, following direction is rotated;
Adopt connecting rod 15 that polylith solar panel a is connected into one successively, be provided with drag rope 22,, be provided with pulley 12 and be used to change the rope direction at drag rope 22 ends at connecting rod 15 two ends; Be provided with support 11 on the end of main cross bar 10, be provided with driving arrangement 13 on support 11, connecting rod 15 is connected with drag rope 22, and drag rope 22 is connected with driving arrangement 13.
More than, constitute the installation unit that a solar panel is evaded sand and dust, sleet, as L≤H1+H2, solar panel a anglec of rotation R＜180 degree; L＞H1+H2, solar panel a anglec of rotation R 〉=180 degree, the L4 value is big more, and solar panel a stability is good more.Connecting rod 15 is arranged on any one side of solar panel a or is symmetrical arranged on both sides.Hold-down support 17 on connecting rod 15 and the solar panel a or be connected with rocker bar bearing 20.
When the driving arrangement 13 at two ends was worked simultaneously, drag rope 22 drive link 15 were moved to the left or to the right, and the solar panel a on the connecting rod 15 rotates slowly.
As shown in Figure 2, when connecting rod 15 moved on the left of direction as shown, the solar panel a on the connecting rod 15 did the clockwise direction rotation slowly, and simultaneously, connecting rod 15 is more and more nearer with the distance of X-axis.
As shown in Figure 3, when driving arrangement 13 works on, drag rope 22 corresponding continuation drive link 15 are to the motion of direction as shown left side, solar panel a is horizontal plane or is tending towards horizontal plane through rotation transformation, be that daylighting face 21 is transformed to up, at this moment, cut off motor power, driving arrangement 13 quits work.In driving arrangement 13 work or any one course of action of stopping, be driving arrangement 13 drive link 15, drag rope 22, and connecting rod 15 or drag rope 22 can not oppositely make driving arrangement 13 work, therefore, when solar panel a is in any state, any solar panel a is relatively stable motionless under the effect of connecting rod 15, even solar panel a also can guarantee when being subjected to wind load or other external force relatively and this main cross bar 10 is relatively stable.The external force that is subjected to as solar panel a is big more, the pulling force of connecting rod 15 and drag rope 22 or pressure are just big more, therefore connecting rod 15 and drag rope 22 must guarantee to have enough intensity, when connecting rod 15 is flexible rope, connecting rod 15 and drag rope 22 should be selected the bigger ropes of tensile strength such as steel wire rope or nylon rope for use, to guarantee safety.
Above scheme, by movable connecting rod 15, polylith solar panel a does simultaneously, equidirectional rotation thereby drive, and makes it daylighting face 21 and is transformed to up, carries out solar power generation; When sand and dust, sleet come the administrative staff or the automatic control system of interim solar power plant above-mentioned connecting rod 15 is carried out reverse drive, make it that daylighting face 21 is transformed to down or inclination or vertical any, can reach the purpose of evading sand and dust, sleet; After sand and dust or sleet, connecting rod 15 carries out aforesaid operations again, can carry out solar power generation.
In the above scheme, main cross bar 10 can be a level, also can be an inclination; Data such as the physical dimension of each solar panel a and each member position, size should be identical, the spacing of installing successively before and after each solar panel a should be with each solar panel a behind the Rotate 180 degree, do not disturb mutually and be as the criterion, be L＞H1+H2, if spacing is the space of conference waste structural system too, should reduce as far as possible.
Connecting rod 15 should be parallel and the X-axis setting, with the direction of motion that guarantees each solar panel a when connecting rod 15 motions, apart from consistency, thereby reaches desirable level of the present invention.If the span of main cross bar 10 is big (for example span reaches 20 meters), can inevitably occur crooked, particularly in the position of span centre, but this can't influence the notion of axis, the connecting rod 15 of this moment also should be arranged in parallel as far as possible with X-axis, and error is more little, approaching more optimal level.
Shown in Fig. 4,5, reflect solar panel a direction of rotation and rotatable angle.
Shown in Fig. 6,7,8,9, be same solar panel a, connecting rod 15 connects in different positions.
Different according to connection support position on the solar panel a and quantity, connecting rod 15 can be set to: connecting rod 15 is arranged on the top of X-axis; Connecting rod 15 is arranged on the below of X-axis; Connecting rod 15 is arranged on the upper and lower of X-axis; Connecting rod 15 is arranged on one side of solar panel a; Connecting rod 15 is arranged on the both sides of solar panel a;
Can be divided into according to the type difference that connects bearing: connecting rod 15 is fixedlyed connected by hold-down support 17 with solar panel a; Connecting rod 15 is fixedlyed connected by rocker bar bearing 20 with solar panel a.
The quantity of bearing, type and position can be selected to use according to different needs.
Shown in Figure 10-14, be the schematic diagram that adopts different driving arrangements.
Figure 10,11 drives external screw thread rod member 28 by external force to rotate, thereby makes the principle of its motion, and this scheme can only drive external screw thread rod member 28 by external force and rotate, and drag rope 22 can not drive external screw thread rod member 28 and moves.
Figure 12 is, the high-pressure and hydraulic oil by hydraulic cylinder 34 promotes hydraulically extensible bar 35 and moves, and the thrust of promotion hydraulically extensible bar 35 should be greater than the pulling force of drag rope 22.
Shown in Figure 13,14, on drive plate 37 (gear 39), brake gear should be set, perhaps adopt worm gear, endless screw transmission agent (not shown) to carry out transmission, drive drive plate 37 motions to prevent drag rope 22.
Above scheme drives power source and should be motor, and adopts and to have the forward and backward function.Enforcement through such scheme not only can make daylighting face 21 evade sand and dust, sleet, also can be used as daylighting face of adjustment 21 and irradiation of sunlight angle, has great significance to improving solar energy generating efficiency.
