Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In addition, the indication concerning directivity mentioned in the embodiment of the present invention is explained as follows: up and down refer to up and down in conventional wisdom when the particular attitude is changed, and the directional indication changes accordingly, when the attachment structure is assembled with the photovoltaic panel array system in normal use. However, the up and down directions are broadly defined as up and down, and are not necessarily on the same straight line in the up and down directions. In this specification, the X direction refers to an outside direction of the photovoltaic panel connection structure (or each component of the photovoltaic panel connection structure), and the Y direction refers to an inside direction of the photovoltaic panel connection structure (or each component of the photovoltaic panel connection structure).
If there is a description of "first", "second", etc. in an embodiment of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
There is a corridor or gap between the first photovoltaic panel 3 and the second photovoltaic panel 4 in the figures, such that the photovoltaic panel cleaning robot cannot walk through the corridor or gap. The first photovoltaic panel 3 and the second photovoltaic panel 4 belong to two photovoltaic panel arrays, and each photovoltaic panel array is provided with an independent light tracking system. The light tracking system can drive the photovoltaic panels in the same array to rotate, so that the planes of the first photovoltaic panel 3 and the second photovoltaic panel 4 are often different in rotation angle, and/or the opposite edges of the first photovoltaic panel 3 and the second photovoltaic panel 4 are larger in height difference. However, the existing connection structure cannot be applied to the connection between the photovoltaic panels or photovoltaic panel arrays on both sides of the aisle with independent light tracking systems. The invention can well solve the technical problem.
As shown in fig. 1, a photovoltaic panel connection structure according to an embodiment of the present invention includes a first connection portion 1 and a second connection portion 2. The first end of the first connecting part 1 is fixedly connected with a first frame 5, the first frame 5 is fixedly installed relative to the first photovoltaic panel 3, and the second end of the first connecting part 1 extends towards the second photovoltaic panel 4; the first end of the second connecting portion 2 is hinged to the second frame 6, the second frame 6 is fixedly mounted relative to the second photovoltaic panel 4, and the second end of the second connecting portion 2 is in lap joint with the first connecting portion 1. The first end and the second end of the first connection portion 1 are opposite end portions of the first connection portion 1, and similarly, the first end and the second end of the second connection portion 2 are opposite end portions of the second connection portion 2.
In particular, the specific embodiment in which the position of the first frame 5 is not changed with respect to the first photovoltaic panel 3 and the position of the second frame 6 is not changed with respect to the second photovoltaic panel 4 may be various. Illustratively, the first frame 5 is a frame of the first photovoltaic panel 3, and the second frame 6 is a frame of the second photovoltaic panel 4, so that the first frame 5 and the first photovoltaic panel 3 rotate synchronously, and the second frame 6 and the second photovoltaic panel 4 rotate synchronously. Exemplarily, the first frame 5 is fixedly connected with the light tracking system of the first photovoltaic panel 3, so as to ensure that the first frame 5 and the first photovoltaic panel 3 rotate synchronously; the second frame 6 is fixedly connected with the light tracking system of the second photovoltaic panel 4, so that the second frame 6 and the second photovoltaic panel 4 can rotate synchronously, but the first frame 5 and the second frame 6 are required to be close to the opposite edges of the first photovoltaic panel 3 and the second photovoltaic panel 4 respectively. Illustratively, the first frame 5 and the second frame 6 are respectively mounted on a rotating shaft of the light tracking system of the first photovoltaic panel 3 and a rotating shaft of the light tracking system of the second photovoltaic panel 4. Those skilled in the art can design specific structures by themselves under the guidance of the present invention, and details are not described herein.
The first end of the first connecting part 1 is fixedly connected with the first frame 5, and the second end of the first connecting part 1 extends towards the second photovoltaic panel 4; the first end of the second connecting part 2 is hinged with the second frame 6, and the second end of the second connecting part 2 can be lapped on the second end of the first connecting part 1 to form an overlapped state. Since the first connection part 1 and the second connection part 2 are independent of each other, they can rotate following the first photovoltaic panel or the second photovoltaic panel, respectively. When the photovoltaic panel rotates, the self structure of the photovoltaic panel connecting structure cannot be damaged.
The sum of the lengths of the first connecting portion 1 and the second connecting portion 2 is greater than the farthest distance of the opposite edges of the first photovoltaic panel 3 and the second photovoltaic panel 4. And the first connection portion 1 and the second connection portion 2 are opposite, i.e., a line between the first connection portion 1 and the second connection portion 2 is parallel to an edge of the first photovoltaic panel 3 or the second photovoltaic panel 4 (the edge refers to an edge parallel to a width direction of a passageway between the first photovoltaic panel 3 and the second photovoltaic panel 4, which is different from the opposite edges of the first photovoltaic panel 1 and the second photovoltaic panel 2). That is, even when the first photovoltaic panel 3 and the second photovoltaic panel 4 rotate independently of each other, resulting in the largest distance between the opposite edges of the first photovoltaic panel 3 and the second photovoltaic panel 4 (the edges of the first photovoltaic panel 3 and the second photovoltaic panel 4 immediately adjacent to the aisle), it is ensured that the second connecting portion 2 overlaps the first connecting portion 1. The rotating shaft of the second connecting part 2 hinged to the second frame 6 is parallel to the edge of the second photovoltaic panel 4 in the aisle. Therefore, when the second connecting part 2 is hinged to the second frame 6, no matter what angle difference and height fall occur between the first photovoltaic panel 3 and the second photovoltaic panel 4, the end part of the second connecting part 2 can be always overlapped above the first connecting part 1, and the first connecting part 1 is fixedly connected to play a good supporting role, so that the passage of the photovoltaic panel connecting structure between the photovoltaic panels forms an effective connecting channel for the photovoltaic panel cleaning robot to walk. The invention skillfully solves the problem of the passage connection between the photovoltaic panel arrays with the light tracking system through an extremely simple structure, and has high technical value and economic value.
Generally, the photovoltaic panel cleaning robot comprises an upper traveling wheel and a lower traveling wheel, and therefore two groups of photovoltaic panel array connection structures are arranged on a passageway between the photovoltaic panels to respectively allow the upper traveling wheel and the lower traveling wheel to pass through.
As shown in fig. 2 and 3, preferably, the second connecting portion 2 includes a second bridge plate 21, and the second bridge plate 21 is used for carrying a traveling wheel of the photovoltaic panel cleaning robot. The second bridge plate 21 is of an upwardly convex configuration, i.e. the second bridge plate 21 is not a flat plate. Illustratively, in an orthographic view of the side surface of the second bridge plate 21 (so-called side surface, see fig. 1, the X direction is the outer side surface direction of the second bridge plate 21, and the Y direction is the inner side surface direction of the second bridge plate 21), the second bridge plate 21 is a regular or irregular arc line, and the irregular arc line may also be a curve with an arc formed by connecting several straight line segments. The central angle corresponding to the radian of the second bridge plate 21 is located below the second bridge plate 21, and is used for ensuring that the second bridge plate 21 is of an upward-convex structure.
The second bridge plate 21 of the second connecting part 2 is provided with an upward bulge, so that when the second bridge plate 21 is lapped on the first connecting part 1, the first connecting part 1 and the second connecting part 2 have no overlarge steps as much as possible. For example, if the second photovoltaic panel 4 is lower than the first photovoltaic panel 3, if the second bridge plate 21 has no curvature, a steeper ascending section may appear from the second bridge plate 21 to the first bridge plate 11, which corresponds to an increased obstacle passing requirement for the cleaning robot.
As shown in FIGS. 3 and 4, preferably, a second hanging plate 22 is provided on the outer side edge (outer side concept is shown in X direction in FIG. 1) of the second bridge plate 21, and the second hanging plate 22 is bent downward relative to the second bridge plate 21. when the bending angle is α, 90 DEG or more and α < 180 DEG or less is provided, the top of the second hanging plate 22 is fixedly connected or integrally connected with the outer side edge of the second bridge plate 21. the second hanging plate 22 extends downward of the second bridge plate 21.
The second hanging plate 22 and the second bridge plate 21 form a bending structure, which can enhance the supporting strength of the second bridge plate 21.
Preferably, the second depending panel 22 is parallel to the side of the second photovoltaic panel 4. Alternatively, the angle between the second depending plate 22 and the second bridge plate is 90 °. For the photovoltaic panel cleaning robot provided with the change gear, the change gear walks along the side face of the photovoltaic panel. When the photovoltaic panel cleaning robot passes through the channel between the photovoltaic panel arrays, the hanging plate parallel to the side wall of the photovoltaic panel can provide the hanging wheel with a walking supporting surface which is equivalent to the side surface of the photovoltaic panel, and the photovoltaic panel cleaning robot is prevented from slipping off the photovoltaic panel.
As shown in fig. 5 and 6, the first connection portion 1 includes a first bridge plate 11. The first bridge plate 11 includes a fixing portion 112 and a receiving portion 111. The fixing portion 112 is fixedly connected to the first frame 5, and the fixing connection may be achieved by welding, screwing, or the like. The receiving portion 111 is fixedly connected to the fixing portion 112 or integrally formed therewith. The receiving portion 111 is inclined downward toward one end of the second connecting portion. In this embodiment, the receiving portion 111 is a section of flat plate, and actually, the receiving portion 111 may also be an arc-shaped plate, and a circle center corresponding to the arc-shaped plate is located below the first bridge plate 11; alternatively, the receiving portion 111 may be a plurality of stages of flat plates fixedly connected, and at least the flat plate closest to the second connection portion 2 may be inclined downward toward one end of the second connection portion 2.
The first bridge plate 11 is inclined downwards towards the end of the second connecting part 2, so that the second bridge plate 21 can be lapped on the top of the first bridge plate 11; on the other hand, after the second bridge plate 21 is lapped with the first bridge plate 11, the lapping part moves downwards along with the end part of the first bridge plate 11, so that the situation that the photovoltaic panel cleaning robot is influenced by an overlarge step between the first bridge plate 11 and the second bridge plate 21 is avoided.
Preferably, the outer side edge of the first bridge plate 11 is provided with a first hanging plate 12, and the outer side of the first bridge plate 11 is shown in the direction X in fig. 1. The first hanging plate 12 is fixedly connected with the first bridge plate or integrally formed with the first bridge plate. The first depending plate 12 is bent downwardly relative to the first bridge plate 11. Preferably, the bending angle is greater than 0 ° and less than or equal to 90 °. The first hanging plate 12 and the first bridge plate 11 are of a bent structure, so that the supporting strength of the first bridge plate 11 can be enhanced.
Preferably, the first depending plate 12 is parallel to the side of the first photovoltaic panel 3. Alternatively, the angle between the first depending panel 12 and the first bridge panel is 90 °. When photovoltaic board cleaning machines people was equipped with the peg, first board 12 that hangs down was parallel with first photovoltaic board 3 side, then first board 12 that hangs down can be as the extension of second board 22 that hangs down, when photovoltaic board cleaning machines people passes through the passageway between the photovoltaic board array, the peg walking holding surface also can be provided for to first board 12 that hangs down that is on a parallel with the photovoltaic board lateral wall, avoids photovoltaic board cleaning machines people from the slippage on the photovoltaic board.
Preferably, the width of the second bridge plate 21 is greater than the width of the first bridge plate 11. Because the second bridge plate 21 is overlapped on the top of the first bridge plate 11, when the width of the second bridge plate 21 is large, the second bridge plate 21 and the second vertical plate 22 connected with the second bridge plate 21 can be effectively ensured to be respectively overlapped on the outer sides of the first bridge plate 11 and the first vertical plate 12, and the fault condition that the two photovoltaic panel arrays are clamped when being overlapped due to large position difference after being respectively rotated is avoided. Moreover, when the first bridge plate 11 is overlapped with the second bridge plate 21, the second hanging plate 22 is located outside the first hanging plate 12, so that the situation that the first bridge plate 11 and the second bridge plate 21 cannot be overlapped is avoided.
Alternatively, referring to fig. 2 and 3, the second bridge plate 21 includes a hinge portion 211, a bridging portion 213, and at least one extension portion 212 disposed between the hinge portion 211 and the bridging portion 213, wherein the extension portion 212 is bent with respect to the hinge portion 211 and the bridging portion 213, respectively, so as to spread out a central angle corresponding to the arc of the second bridge plate 21. The hinge portion 211, the bridging portion 213 and the extension portion 212 are all flat plate structures, and the extension portion 212 is respectively and fixedly connected with the hinge portion 211 and the bridging portion 213, or the extension portion 212 is integrally formed with the hinge portion 211 and the bridging portion 213 and then bent. When the aisles between the photovoltaic panel arrays are wide, the length of extensions 212 in the aisle width direction may be increased, or the number of segments of extensions 212 may be increased.
Since the hinge portion 211, the bridging portion 213 and the extension portion 212 are all flat plate structures, the manufacturing process of the second bridge plate 21 is simple. For example, a flat plate may be used, the hinge portion 211, the overlapping portion 213 and the extending portion 212 are bent, and then one side edge of the flat plate is cut and slightly adjusted to form a second hanging plate.
The hinge portion 211 is for hinging with the second frame 6. Illustratively, hinge portion 211 is fixedly connected to second hinge assembly 72, second frame 6 is fixedly connected to first hinge assembly 71, and first hinge assembly 71 and second hinge assembly 72 are hingedly connected. It should be noted that the present embodiment merely provides an exemplary illustration of the hinge connection manner, and should not be construed as a limitation to the present invention.
The overlapping part 213 is used to overlap over the first connection part 1. And, the overlapping part 213 is inclined downward toward one end of the first connecting part 1. The downward inclination of the end of the overlapping part 213 is substantially the same as the downward inclination of the end of the first bridge plate 11, which facilitates the overlapping of the second bridge plate 21 on the top of the overlapping part 213 of the first bridge plate 11; on the other hand, the contact part of the first bridge plate 11 and the second bridge plate 21 moves downwards, and the situation that the photovoltaic panel cleaning robot is influenced by overlarge steps after the first bridge plate 11 and the second bridge plate 21 are lapped is avoided.
Preferably, a damping component is arranged at the hinged part of the second connecting part 2 and the second frame 6. Illustratively, the second frame 6 and the second connecting portion 2 may be hinge-connected using a damping hinge. The damping component is arranged, on one hand, strong collision between the second connecting part 2 and the first connecting part 1 is avoided, and the service life of the component is prolonged; on the other hand, the second connecting part 2 is slowly lapped on the first connecting part 1, and the lapping effect is guaranteed.

The second bridge plate 21 is an arc-shaped plate, and the circle center corresponding to the second bridge plate 21 is located below the second bridge plate 21. The first bridge plate 11 is also an arc-shaped plate, and the circle center corresponding to the first bridge plate 11 is located below the first bridge plate 11. The ends of the first bridge plate 11 and the second bridge plate 21 close to each other are inclined downward.
