[0025] The following provides a detailed description of the specific implementation mode of the present disclosure in conjunction with the accompanying drawings. It should be understood that the specific implementation mode described here is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise stated, the orientation terms such as "inside, outside" refer to "inside, outside" relative to the contour of the corresponding component itself. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure, and should not be construed as a limitation of the present disclosure.

[0027] The bridge device in the exemplary embodiments of the present disclosure will be described below in conjunction with the accompanying drawings.

[0028] As Figures 1 to 6 shown, in a first aspect of the present disclosure, a bridge device is provided. The bridge device is used to connect two adjacent photovoltaic panel frames 8 and includes a bridge body 1 and a connecting member 2. Among them, the bridge body 1 includes a mating portion 4; the connecting member 2 is connected to both ends of the bridge body 1 and is used to connect to the corner of the photovoltaic panel frame 8, and includes a first connecting section 21 and a second connecting section 22 that are vertically arranged; the first connecting section 21 includes a first connecting portion 211 that can be detachably connected to the mating portion 4, so that after the first connecting portion 211 is connected to the mating portion 4, the bridge body 1 can rotate relative to the first connecting section 21, that is, the bridge device can connect two photovoltaic panel frames 8 with a vertical drop; the second connecting section 22 includes a second connecting portion 221 that can be detachably connected to the mating portion 4, so that after the second connecting portion 221 is connected to the mating portion 4, the bridge body 1 can rotate relative to the second connecting section 22, that is, the bridge device can connect two photovoltaic panel frames 8 with a horizontal deviation. When the bridge device needs to connect two photovoltaic panel frames 8 with a vertical drop, the first connecting portion 211 can be connected to the mating portion 4 after adjusting the angle of the bridge body 1, and when the bridge device needs to connect two photovoltaic panel frames 8 with a horizontal deviation, the second connecting portion 221 can be connected to the mating portion 4 after adjusting the angle of the bridge body 1. Based on this, the bridge device of the present disclosure can not only connect two normally arranged photovoltaic panel frames 8, but also connect two photovoltaic panel frames 8 with a vertical drop or a horizontal deviation according to the installation environment at that time, improving the applicability of the bridge device and ensuring the cleaning efficiency of the photovoltaic cleaning robot.

[0029] In some embodiments of the present disclosure, as Figure 3 shown, a first bending portion 212 is formed at one end of the first connecting section 21 facing away from the second connecting section 22 to form a U-shaped structure with the second connecting section 22 that can be inserted into one side of the corner of the photovoltaic panel frame 8. The first bending portion 212 can make the end of the first connecting section 21 parallel to the second connecting section 22. When the connecting member 2 is connected to the photovoltaic panel frame 8, the photovoltaic panel frame 8 can be inserted between the first bending portion 212 and the second connecting section 22, so that the first bending portion 212 and the second connecting section 22 can be clamped on the photovoltaic panel frame 8 to ensure the stability of the connecting member 2 after being connected to the photovoltaic panel frame 8.

[0030] In some embodiments, as Figure 3As shown, the bridge device further includes a fixing member 3. The fixing member 3 is connected to one end of the second connecting section 22 facing away from the first connecting section 21 to clamp the other side of the corner of the photovoltaic panel frame 8. Fixing holes may be provided on the second connecting section 22 adjacent to the second connecting portion 221, and fixing mating holes may be provided on the fixing member 3 so that the fixing member 3 and the second connecting section 22 can be connected together by fasteners 10 such as bolts or screws. In this way, the fixing member 3 can cooperate with the U-shaped structure formed by the first connecting section 21 and the second connecting section 22 to clamp the two sides of the corner of the photovoltaic panel frame 8 respectively, thereby improving the stability of the connecting member 2 after being connected to the photovoltaic panel frame 8, and further ensuring the stability of the bridge device when the subsequent photovoltaic cleaning robot passes through, and ensuring its cleaning efficiency.

[0031] Among them, as Figure 3 shown, the fixing member 3 may include two clamping plates 31 oppositely arranged in the first direction A. A clamping opening 32 facing the other side of the corner of the photovoltaic panel frame 8 is formed between the two clamping plates 31. Specifically, the two clamping plates 31 may extend toward the other side of the corner of the photovoltaic panel frame 8, that is, the opening of the clamping opening 32 faces the other side of the corner of the photovoltaic panel frame 8, so that the photovoltaic panel frame 8 can be connected to the fixing member 3 after being inserted into the clamping opening 32 to ensure the stability of the bridge device after being connected to the photovoltaic panel frame 8.

[0032] To improve the stability between the clamping opening 32 and the photovoltaic panel frame 8, as Figure 3 shown, at least one of the two clamping plates 31 is provided with a second bending portion 311, and / or at least one of the two clamping plates 31 is provided with an anti-slip structure 312 facing the inside of the clamping opening 32. As Figure 6 shown, the second bending portion 311 can abut against the outer side of the photovoltaic panel frame 8 to ensure the stability of the connection between the fixing member 3 and the photovoltaic panel frame 8, and the anti-slip structure 312 provided on the clamping plate 31, such as anti-slip stripes, can increase the stability after the clamping plate 31 is connected to the photovoltaic panel frame 8.

[0033] In some embodiments of the present disclosure, as Figure 1 and Figure 6As shown in the figure, the first connecting portion 211 is connected to the mating portion 4 through the fastener 10, and the second connecting portion 221 is connected to the mating portion 4 through the fastener 10. For example, when the bridge body 1 needs to be connected to the frames of two photovoltaic panels 8 with a horizontal deviation, the fastener 10 can be provided between the second connecting portion 221 and the mating portion 4 after adjusting the angle of the bridge body 1 to ensure their connection. At this time, there is no connection relationship between the first connecting portion 211 and the mating portion 4; when the bridge body 1 needs to be connected to the frames of two photovoltaic panels 8 with a vertical drop, the fastener 10 between the second connecting portion 221 and the mating portion 4 needs to be removed, and the position and angle of the bridge body 1 need to be adjusted so that the second connecting portion 221 can be connected to the mating portion 4 through the fastener 10. Based on this, the switching between the two connection states of the bridge device is realized.

[0034] It should be noted that when the fastener 10 fixes between the first connecting portion 211 and the mating portion 4 or between the second connecting portion 221 and the mating portion 4, the final fixing can be carried out after the angle adjustment of the bridge body 1 is completed, so as to facilitate the bridge body 1 to change its position to be connected to the frame of the photovoltaic panel 8.

[0035] In the embodiments of the present disclosure, as Figure 4 shown, the bridge body 1 includes a first mating section 11 and a second mating section 12 arranged vertically, and the mating portion 4 is provided on the second mating section 12; when the mating portion 4 is connected to the first connecting portion 211, the first mating section 11 and the first connecting section 21 are arranged in parallel; when the mating portion 4 is connected to the second connecting portion 221, the second mating section 12 and the second connecting section 22 are arranged in parallel. That is, one side of the bridge body 1 is used to be connected to the connecting member 2, and the other side is used for the photovoltaic cleaning robot to pass through.

[0036] Among them, as Figure 4 shown, an avoidance notch 9 is formed at one end of the second mating section 12 close to the connecting member 2. The avoidance notch 9 can prevent the bridge body 1 from interfering with other parts of the connecting member 2 during rotation, thereby restricting the rotation angle of the bridge body 1 and affecting the connection effect of the bridge device.

[0037] In some embodiments of the present disclosure, as Figure 4 shown, both the first connecting portion 211 and the second connecting portion 221 are configured as connection holes 5, and the mating portion 4 is configured as a waist-shaped hole 6 that can cooperate with the connection hole 5 through the fastener 10. To ensure the stability of the bridge body 1 after being connected to the connecting member 2.

[0038] In addition, a plurality of through holes may be provided at intervals along the extending direction of the bridge body 1 on the first fitting section 11 and the second fitting section 12 of the bridge body 1. In this way, a plurality of bridge bodies 1 can be connected to each other under the action of fasteners 10 such as bolts or screws, so as to increase the length of the bridge device and improve the applicable range of the connection of the bridge device. In addition, the through holes may be through holes with inner and outer flanges to increase the friction between the bridge body 1 and the rollers of the photovoltaic cleaning robot, and avoid the situation of slipping when the photovoltaic cleaning robot passes through the bridge body 1.

[0039] In a second aspect of the present disclosure, a photovoltaic power station is provided, which includes a plurality of photovoltaic panels 7, a plurality of photovoltaic panel frames 8 corresponding to the photovoltaic panels 7 one by one, and the above-mentioned bridge device. The photovoltaic panel 7 is sleeved inside the photovoltaic panel frame 8, and the bridge device is connected between two adjacent photovoltaic panel frames 8. This photovoltaic power station has all the beneficial effects of the above-mentioned bridge device, and the present disclosure will not repeat them here.

[0040] In summary, the present disclosure exemplarily shows the use process of the bridge device.

[0041] The first bending portion 212 of the connecting member 2 and the second connecting section 22 cooperate to be clamped on one side of the corner of the photovoltaic panel frame 8, and the two clamping plates 31 on the fixing member 3 are clamped on the other side of the corner of the photovoltaic panel frame 8. When there is a vertical drop between the two photovoltaic panel frames 8, the angle of the bridge body 1 can be adjusted so that the second connecting portion 221 can be connected through the fastener 10 and the fitting portion 4. When there is a horizontal deviation between the two photovoltaic panel frames 8, fasteners 10 can be provided between the second connecting portion 221 and the fitting portion 4 after adjusting the angle of the bridge body 1. Based on this, in addition to connecting two normally arranged photovoltaic panel frames 8, the bridge device of the present disclosure can also connect two photovoltaic panel frames 8 with a vertical drop or a horizontal deviation according to the installation environment at that time, improving the applicability of the bridge device and ensuring the cleaning efficiency of the photovoltaic cleaning robot.

However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0043] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. In order to avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0044] In addition, any combination can be made among various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and the same should be regarded as the content disclosed by the present disclosure.
