Second embodiment: flat unipolar photovoltaic power generation device
Mainly relates to an improvement of a bridge frame of a flat single-shaft photovoltaic power generation device. The bridge is a device which is arranged between the two flat single shafts and is used for the cleaning robot to walk from the photovoltaic module on one flat single shaft to the photovoltaic module on the other flat single shaft.
The construction of the bridge of the present flat single-shaft photovoltaic power plant is shown in fig. 9 and 10.
Referring to fig. 9, two photovoltaic modules 201 are respectively disposed on two flat single shafts 205, and can be driven by the flat single shafts 205 to rotate, so as to realize tracking of sunlight.
Purlins 203 are fixed on the flat single shaft 205, the purlins 203 are perpendicular to the flat single shaft 205, cross beams 202 are fixed on the purlins 203, the cross beams 202 are used for mounting a bridge, and the cross beams 202 are preferably square tubular beams.
Wherein the bridge comprises two of the first embodiment see-saw bridge structures 100, the two see-saw bridge structures 100 being symmetrically arranged about a single, flat axis 205.
Taking the see-saw bridge structure 100 on the right rear side in fig. 9 as an example, the first turning beam 120 of the see-saw bridge structure 100 is disposed on the flat single shaft 205 on the left upper side, specifically on the cross beam 202 on the purlin 203 of the flat single shaft 205. Further referring to fig. 9 and 10, a rotating shaft (i.e., a center of rotation) 204 is provided on the cross member 202 at a position above the flat single shaft 205, and a first shaft hole 134 (see fig. 6 and 7) at an end of the first swing beam 120 is engaged with the rotating shaft 204 so that the first swing beam 120 can swing about the rotating shaft 204.
The second swing beam 130 of the rocker bridge structure 100 is disposed on the lower right flat single shaft 205, specifically on the cross beam 202 on the purlin 203 of the flat single shaft 205. The arrangement is the same as that of the first swing beam 120.
The see-saw bridge structure 100 on the front left side of fig. 9 is arranged in the same way on two flat single shafts 205.
As shown in fig. 9, when the cross beam 202 on the lower right flat single shaft 205 is tilted upward, the second turning beam 130 of the see-saw bridge structure 100 on the rear right side is tilted upward against the tilted cross beam 202, and the first turning beam 120 of the see-saw bridge structure 100 is also raised; when the upturned beam 202 begins to descend, the first turning beam 120 and the second turning beam 130 of the see-saw bridge structure 100 both follow the descent until the beams 202 on the two flat single shafts 205 are parallel, and both see-saw bridge structures 100 are attached to the beams 202 on the flat single shafts. When the cross beam 202 on one flat axle 205 is lowered, one turning beam of the rocker bridge structure 100 will engage the stationary flat axle, while the other turning beam will follow the lowering until the limit in the bushing structure 110 (see fig. 1) is raised to the limit.
It can be seen that, in the above embodiment, two turning beams are added on the basis of the conventional sleeve structure 110, and the two turning beams form a turning center on the square pipe on the flat single-shaft purline, so that the turning beams can rotate around the turning center to drive the sleeve structure 110 to turn around, and when the two flat single shafts 205 are at any angle, the sleeve structure 110 cannot be disengaged.
With further reference to fig. 9 and 10, the first turning beam 120 is sleeved with a U-shaped groove 140 corresponding to the turning center thereof, the U-shaped groove 140 is connected to a rotating shaft (i.e., the turning center) 204 on the cross beam 202, and a notch 143 is formed in a position of the cross plate of the U-shaped groove 140 corresponding to the turning center, so that the U-shaped groove 140 can turn around the turning center along with the first turning beam 120. During the rotation of the first rotating beam 120, when the bottom of the notch 143 touches the cross beam 202, the first rotating beam cannot rotate any more, so that the relative position between the first rotating beam 120 and the cross beam 202 on the purline is limited.
Similarly, a U-shaped groove 140 is provided in the second turning beam 130.
When the first and second swing beams 120 and 130 are angle steels (as shown in fig. 6 and 7), the horizontal plate portion (i.e., the first horizontal plate portion 133) of the angle steels is attached to the top of the cross beam 202, and the vertical plate portion (i.e., the first vertical plate portion 134) of the angle steels is also attached to the outer side portion of the cross beam 202, so that lateral limitation can be formed, and a more stable effect can be achieved.
The sleeve structure 110 therein also has a length limiting device for preventing the inner and outer tubes of the sleeve structure 110 from disengaging. Referring to fig. 4, the length limiting device comprises a spring 114 and a limiting rope 113, the spring 114 and the limiting rope 113 are both arranged inside the casing structure in a penetrating manner, one end of the spring 114 and the other end of the limiting rope 113 are fixed on a screw rod at the end of the outer pipe 111, the other end of the spring is fixed on a screw rod at the end of the inner pipe 115, and the limiting rope 113 is preferably a steel wire rope.
The third embodiment: flat unipolar photovoltaic power generation device of another kind
Figure 11 shows another flat single-shaft photovoltaic power plant. The difference from the flat single-shaft photovoltaic power generation device shown in fig. 9 is that: in fig. 9, the height of the photovoltaic module in the flat single shaft 205 is smaller and is a photovoltaic panel, while in the embodiment shown in fig. 11, the height of the photovoltaic module 201 on the flat single shaft 205 is larger and is formed by a plurality of photovoltaic panels.
It is to be noted that, unless otherwise specified, the terms "first", "second", and the like are used for distinguishing different devices having the same name, and are not to be construed as encompassing sequential, primary, secondary, or important meanings.
