Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic arrays, specifically relating to bridges and photovoltaic arrays. Background Technology

[0002] A photovoltaic array is the core power generation unit in a photovoltaic power generation system. It is composed of multiple photovoltaic panels connected in series and parallel, which can efficiently convert solar energy into electrical energy.

[0003] In actual operation, photovoltaic arrays need to be cleaned regularly to prevent dust, dirt and other contaminants from adhering to the surface of the photovoltaic panels and affecting their absorption and conversion efficiency of sunlight. Traditional manual cleaning has problems such as low efficiency, high cost and poor safety. In actual photovoltaic array cleaning, photovoltaic cleaning robots are used to carry out cleaning work, thereby solving the problems of low efficiency and high risk of manual cleaning and promoting the transformation of photovoltaic operation and maintenance towards unmanned work.

[0004] However, during the cleaning process using a photovoltaic cleaning robot, since the photovoltaic array is composed of multiple photovoltaic panels, there will be certain gaps between adjacent photovoltaic panels. When the photovoltaic cleaning robot passes through these gaps, it may get stuck, fall off, or be unable to move normally, resulting in the failure of the cleaning work. Existing bridge connectors need to be fixed to the photovoltaic panels with fasteners (bolts or screws). During the installation process, stripping may occur, which may cause the bridge to be unable to be installed normally.

[0005] Therefore, simplifying the installation of cable trays is a problem that needs to be solved. Utility Model Content

[0007] Technical solution: Cable tray, including:

[0008] The middle section covers at least two surfaces to be connected;

[0009] The locking part has deformation characteristics. By applying a pre-tightening force through deformation, the middle part and the part to be connected are locked together to form an integral structure.

[0010] In a further embodiment, the middle portion covers the surfaces of at least two portions to be connected;

[0011] The locking part has deformation characteristics. By applying a pre-tightening force through deformation, the middle part and the part to be connected are locked together to form an integral structure.

[0012] In a further embodiment, the locking part includes a plastic component;

[0013] The plastic part achieves the connection between the parts to be connected through mechanical interlocking generated by permanent deformation.

[0014] In a further embodiment, the elastic element and the middle part are an integral structure.

[0015] In a further embodiment, the plastic part and the middle part are separate structures.

[0024] Beneficial Effects: This utility model relates to a bridge and a photovoltaic array. To simplify the installation of the bridge, this device includes a middle section, a locking section, and a bending component. During bridge installation, the middle section is positioned between two adjacent photovoltaic panels. The bending component then bends and deforms, allowing the middle section to be initially positioned. The locking section then works, using plastic deformation or elasticity to secure the bridge to the adjacent photovoltaic panels, thus completing the installation. When using the elastic component to fix the bridge, few tools are needed to secure it to the photovoltaic panel frame, improving installation speed and preventing connectors from falling off. This ensures the photovoltaic cleaning robot can effectively clean the photovoltaic array. Attached Figure Description

[0039] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0041] Example 1:

[0042] The specific implementation of the photovoltaic array of this application includes:

[0043] The photovoltaic panels are multiple in number and connected in series, parallel, or series-parallel configurations; the middle part 1 covers the surfaces of at least two parts to be connected; the locking part 2 has deformation characteristics and applies a pre-tightening force through deformation, so that the middle part 1 and the parts to be connected are locked together to form an integral structure; the middle part 1 is secured to the adjacent photovoltaic panels by the deformation of the locking part 2 and the bending part 3.

[0044] The locking part 2 includes an elastic element 21; the middle part 1 is engaged with the part to be connected by means of the deformation force provided by the elastic element 21.

[0045] The intermediate part 1 has a U-shaped structure, including a main end and two extension ends 11 and 12. The extension ends 11 and 12 are symmetrically arranged on the main end, and the extension end 11 with a larger extension length is the first extension end 11 and the extension end 11 with a smaller extension length is the second extension end 11. The locking part 2 is located on the first extension end 11 and 12, and the bending part 3 is located on the second extension end 11 and 12. The intermediate part 1 can be snapped onto the photovoltaic panel frame, and at least two locking parts 2 are symmetrically arranged on the intermediate part 1.

[0046] The elastic element 21 is an elastic sheet 211. The elastic sheet 211 has a predetermined deformation capacity. In the initial state, the plane where the elastic sheet 211 is located is parallel to the plane where the side wall of the middle part 1 is located, so that the middle part 1 can be locked on the photovoltaic panel frame and can be used to connect two photovoltaic panels, thereby forming a photovoltaic panel cable tray.

[0047] During installation, the operator first places the middle part 1 between two adjacent photovoltaic panels, then presses the elastic sheet 211 to bring it closer to the bending part 3. The position of the middle part 1 is then adjusted so that the elastic sheet 211 abuts against the photovoltaic panel frame. At this point, the elastic sheet 211 deforms, generating a certain preload, which allows the photovoltaic panel frame to be positioned between the elastic sheet 211 and the main body end 12 of the extension end 11, completing the installation of the bridge frame. Then, the bending part 3 is bent to complete the secondary positioning of the bridge frame, ensuring that the photovoltaic cleaning robot can smoothly cross the gaps in the photovoltaic array 4.

[0048] The elastic element 21 and the middle part 1 are an integral structure;

[0049] During installation, the operator only needs to change the deformation of the elastic sheet 211 and make the deformed elastic sheet 211 abut against the photovoltaic panel frame to complete the installation of the cable tray. No extra work is required in this process. The middle part 1 is simply snapped onto the frame, and the deformation of the elastic sheet 211 is changed to complete the installation of the cable tray.

[0050] The middle part 1 is provided with a bending member 3; through the deformation of the bending member 3, the middle part 1 is locked onto the part to be connected. There are at least two bending members 3. The bending member 3 includes, but is not limited to, a bending plate. By using a tool to bend the bending plate, the middle part 1 can be locked onto the frame, ensuring that the middle part 1 can be installed smoothly. The bending member 3 is a plastic deformation.

[0051] Example 2:

[0052] The specific implementation of the photovoltaic array 4 in this application differs from that in embodiment 1 in that: the elastic member 21 is a convex hull 212, which has a predetermined deformation capability. Through the deformation of the convex hull 212, the middle part 1 can be snapped onto the frame during the installation of the middle part 1.

[0053] During installation, the protrusion 212 is compressed and deformed, and then the bending plate is bent. The installation of the middle part 1 is completed with the cooperation of the bending plate and the protrusion 212. In this process, only pressing and bending are required to complete the installation of the cable tray.

[0054] Example 3:

[0055] The specific implementation of the photovoltaic array 4 in this application differs from that in embodiment 1 in that: the elastic member 21 includes a plurality of comb-shaped clamping plates 213 disposed on the middle part 1. By bending the clamping plates 213, they abut against the photovoltaic panel frame, thereby completing the limiting installation work of the middle part 1.

[0056] Example 4

[0057] This is a specific embodiment of the photovoltaic array 4 of this application, which differs from Embodiment 1 in that: the locking part 2 includes a plastic part 22; the plastic part 22 achieves the connection between the parts to be connected through mechanical interlocking generated by permanent deformation; the plastic part 22 and the intermediate part 1 are separate structures; the intermediate part 1 is provided with mounting holes coupled to the plastic part 22;

[0058] The plastic part 22 includes, but is not limited to, rivets 221 or expansion sleeve structures;

[0059] By passing one end of the rivet 221 through the mounting hole and then changing the connection state of the rivet 221 with a rivet gun, the rivet 221 undergoes plastic deformation, which allows it to apply a certain preload to the photovoltaic panel frame and the bridge bracket, thus completing the installation of the bridge bracket.

[0060] Example 5

[0061] This is a specific implementation of the photovoltaic array 4 of this application, which differs from embodiments 1-4 in that: the middle part 1 can be set to different lengths to facilitate the installation of different photovoltaic modules. Working principle explanation: When the elastic element 21 is an elastic sheet 211, in the installation state, the operator first places the middle part 1 between two adjacent photovoltaic panels, then presses the elastic sheet 211, causing it to move closer to the bending element 3. Then, the position of the middle part 1 is adjusted so that the elastic sheet 211 abuts against the photovoltaic panel frame. At this time, due to the deformation of the elastic sheet 211, a certain pre-tightening force is generated, thereby enabling the photovoltaic panel frame to be located between the elastic sheet 211 and the main body end 12 of the extension end 11, completing the installation of the bridge frame. Then, the bending element 3 is bent to complete the secondary limiting of the bridge frame, ensuring that the photovoltaic cleaning robot can smoothly cross the gaps in the photovoltaic array 4.

[0062] When the elastic element 21 is a protrusion 212, during the installation process, the protrusion 212 is squeezed and deformed, and then the bending plate is bent. Thus, the installation of the middle part 1 is completed with the cooperation of the bending plate and the protrusion 212. In this process, only pressing and bending are required to complete the installation of the cable tray.

[0063] When the locking part 2 is a plastic part 22 (rivet 221), one end of the rivet 221 is passed through the mounting hole, and then the connection state of the rivet 221 is changed by the rivet gun, so that the rivet 221 undergoes plastic deformation, so that it can apply a certain preload to the photovoltaic panel frame and the bridge frame, and complete the installation of the bridge frame.

[0064] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
