Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a photovoltaic inverter installation structure. Background Technology

[0002] Inverters are essential electrical devices in photovoltaic systems, used to convert the direct current (DC) generated by photovoltaic panels into alternating current (AC). In existing technologies, the preferred installation location for inverters is one with good ventilation and shade, minimizing sunlight exposure and utilizing natural wind for cooling, effectively dissipating heat from the inverter. However, in actual installation, due to limitations imposed by other factors, sometimes installation is done in locations without shade, such as on corrugated steel roofs. Since the photovoltaic panels are directly fixed to the roof, the space between the panels and the roof tiles cannot accommodate the inverter. Often, holes are drilled in the roof to secure the bracket, and the inverter is installed vertically on the bracket. During wiring or later maintenance, the inverter's wiring terminals face downwards, making it inconvenient for personnel to observe. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing photovoltaic inverter brackets are vertically installed, which is inconvenient for installation and maintenance.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A photovoltaic inverter mounting structure includes a bracket and a sunshade. The bracket includes an I-shaped base, support rods, and a mounting frame. Two support rods are vertically and parallel to each other on both sides of the I-shaped base. The sunshade is supported by the two support rods. The bottom of the mounting frame is hinged to the two support rods via a pivot, and the top of the mounting frame is hinged via a straight hinge. When the straight hinge is extended, the mounting frame rotates around the pivot.

[0006] The support rod and the mounting bracket are provided with fixing holes, and a fixing rod is inserted into the fixing holes; one end of the straight hinge is hinged to the support rod, and the other end of the straight hinge is hinged to the mounting bracket.

[0007] Furthermore, when the hinge is straight, the rotation angle of the mounting bracket around the pivot is less than or equal to 15 degrees.

[0008] Furthermore, the support rod and the mounting bracket are provided with limit holes, and a limit rod passes through the limit holes.

[0009] Furthermore, a connecting plate is provided on the I-shaped base frame.

[0010] Furthermore, the sunshade is a straight ramp, and diagonal bracing is provided between the sunshade and the support frame.

[0011] Furthermore, reinforcing ribs are provided between the support frame and the I-shaped base frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This application improves upon the existing bracket by hinged mounting bracket to support rod, enabling the inverter fixed on the mounting bracket to rotate together, exposing the bottom wiring position. The rotation angle is limited by a single-slot hinge, temporarily placing the inverter in an upward tilt state, which facilitates wiring and maintenance.

[0014] 2. In this application, the rotation tilt angle of the mounting bracket is limited by the length of the single-hinged hinge. With the help of the limiting hole and the limiting rod, the mounting bracket is kept in a tilted state, which facilitates the upward tilting installation of the inverter.

[0015] 3. In this application, the connecting plate shields the I-shaped base frame, forming a flat surface. In areas without strong winds, counterweights can be placed directly on the connecting plate without drilling holes in the roof. Diagonal braces are provided between the sunshade and the support frame, and reinforcing ribs are provided between the support frame and the I-shaped base frame to increase the stability of the connection.

[0024] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0025] like Figure 1-3 As shown, a photovoltaic inverter mounting structure is disclosed, including a bracket and a sunshade 1. The bracket includes an I-shaped base frame 2, support rods 3, and a mounting frame 4. Two support rods 3 are vertically and parallel to each other on both sides of the I-shaped base frame 2. The sunshade 1 is supported by the two support rods 3. The bottom of the mounting frame 4 is hinged to the two support rods 3 via a pivot 6, and the top of the mounting frame 4 is hinged via a straight hinge 5. When the straight hinge 5 is extended, the mounting frame 4 rotates around the pivot 6. Fixing holes are provided on the support rods 9 and the mounting frame 4, and fixing rods 7 pass through the fixing holes. One of the straight hinges 5... One end is hinged to the support rod 3, and the other end of the straight hinge 5 is hinged to the mounting bracket 4; the fixing hole and the fixing rod 7 work together to ensure that the mounting bracket 4 is stably in a vertical position, realizing the vertical installation of the inverter. When wiring or maintaining the inverter, the fixing rod 7 can be pulled out, allowing the mounting bracket 4 and the inverter to rotate around the rotating shaft 6 at a small angle (the connecting wire is reserved with a certain length, which does not affect the small range of rotation of the inverter), exposing the bottom wiring position. The rotation angle is limited by the straight hinge 5, so that the inverter is temporarily in an upward tilted state, which facilitates personnel to perform wiring and maintenance.

[0026] Among them, the sunshade 1 is a straight slope, and the sunshade 1 is provided with a diagonal brace 9 between the sunshade 1 and the support frame; the support frame and the I-shaped base frame 2 are provided with a reinforcing rib 8; the sunshade 1 is a straight slope, which facilitates the sliding of rain and snow. Example 2

[0027] like Figure 1-2 As shown, this embodiment is obtained by adding technical features such as limiting holes and limiting rods 10 on the basis of embodiment one. The remaining technical features are the same as those in embodiment one, and the similarities will not be repeated here. The difference between this embodiment and embodiment one is that when the straight hinge 5 is straight, the rotation angle of the mounting bracket 4 around the rotating shaft 6 is less than or equal to 15 degrees (which can be adjusted according to the specified tilt installation angle of the inverter so that the tilt angle of the inverter does not exceed the specified value); the support rod 3 and the mounting bracket 4 are provided with limiting holes, and the limiting rods 10 are inserted into the limiting holes.

[0028] In this embodiment, the rotation tilt angle of the mounting bracket 4 is limited by the length of the straight hinge 5, and with the help of the limiting hole and the limiting rod 10, the mounting bracket 4 is kept in a tilted state, which facilitates the upward tilting installation of the inverter. Example 3

[0029] like Figure 1-2 As shown, this embodiment is obtained by adding technical features such as connecting plate 11 on the basis of embodiment one or two. The remaining technical features are the same as those in embodiment one or two. The similarities will not be repeated here. The difference between this embodiment and embodiment one or two is that the connecting plate 11 is provided on the I-shaped base frame 2.

[0030] In this embodiment, the connecting plate 11 shields and connects the I-shaped base frame 2 to form a plane. In areas without strong winds, counterweights can be placed directly on the connecting plate 11 without drilling holes in the roof.

[0031] The overall usage process formed by the above embodiments is as follows: After the I-shaped base frame 2, support rod 3, mounting frame 4 and sunshade 1 are installed on the roof, the inverter is installed on the mounting frame 4 according to the existing installation method. After removing the fixing rod 7, the inverter is tilted upward at a certain angle, and then the inverter is wired. After the wiring is completed, the inverter is rotated by the mounting frame 4 to make it vertical, and the fixing rod 7 is inserted to keep the inverter in a vertical state; or after the wiring is completed, the limiting rod 10 is inserted to keep the inverter in a tilted state.

[0032] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
