Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic inverter installation, and more specifically, to a photovoltaic inverter installation mechanism. Background Art

[0002] Photovoltaic inverters, also known as power regulators, are inverters that can convert the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency. They are one of the balancers of the photovoltaic array system.

[0003] PV inverters consist of a boost circuit and an inverter bridge circuit and can be used in commercial power transmission systems and off-grid power grids. They primarily consist of switching elements such as transistors, which repeatedly switch on and off to convert DC input into AC output. PV inverters offer features such as automatic start and stop, tracking control, and protection against independent operation.

[0004] In photovoltaic power plants, photovoltaic inverters are typically mounted on brackets below the photovoltaic panels. In buildings, they are typically mounted on walls. To facilitate installation, mounting ears are typically welded or bolted to the inverter's housing, and then bolted to the bracket or wall. These ears are typically plates with through-holes.

[0005] On the bracket below the photovoltaic panel assembly, due to its simple structure, a separate bracket must be installed to mount the photovoltaic inverter, otherwise the photovoltaic inverter will not have sufficient force-bearing positions. When installing on a wall, the bracket must also be installed before the photovoltaic inverter can be installed. And because the photovoltaic inverter is quite heavy, even after the bracket is installed, the entire photovoltaic inverter must be stabilized and supported. After aligning the through holes and the bracket holes, the position must be determined before the photovoltaic inverter can be installed. During this process, the staff must lift the photovoltaic inverter. Due to the heavy and large chassis, the photovoltaic inverter will shift if the staff is lax, resulting in slow installation.

[0006] Therefore, it is necessary to redesign the installation structure of this type of photovoltaic inverter to simplify the installation method so as to improve the efficiency during the actual installation of the photovoltaic inverter. Summary of the Invention

[0007] The purpose of the utility model is to provide a photovoltaic inverter mounting mechanism, which uses a bottom bracket for support and leverage, so that workers can reduce their effort and can align the first mounting hole and the second mounting hole more quickly and easily, thereby facilitating the subsequent installation of the photovoltaic inverter box with mounting bolts, making the actual installation of the photovoltaic inverter box faster and more efficient.

[0010] The top mounting frame includes a top horizontal strip; the bottom bracket includes a bottom horizontal strip and a bottom supporting plate, and the bottom end of the bottom horizontal strip is vertically fixedly connected to the top surface of the bottom supporting plate;

[0011] A plurality of second mounting holes are evenly arranged on the top horizontal strip plate and the bottom horizontal strip plate respectively;

[0012] The top mounting ear and the top horizontal strip are connected to each other, and the bottom mounting ear and the bottom horizontal strip are connected to each other by mounting bolts passing through the first mounting hole and the second mounting hole respectively;

[0013] The mounting bolt is further used to pass through the second mounting hole and the pre-set mounting hole at the position to be installed, so as to realize the installation connection between the top mounting bracket and the bottom bracket at the position to be installed.

[0016] The top back plate is higher than the top horizontal strip and is evenly penetrated with a plurality of third mounting holes. The mounting bolts are also used to pass through the third mounting holes and the preset mounting holes to achieve the connection between the top mounting frame and the position to be installed.

[0017] As a preferred technical solution of the present invention, the bottom bracket further comprises a bottom back plate, the bottom end of the bottom back plate is fixedly and vertically connected to the rear side of the bottom support plate, the height of the bottom back plate is higher than the height of the bottom horizontal strip plate, and a parallel gap cavity is also provided between the bottom back plate and the bottom horizontal strip plate;

[0018] The bottom back plate is evenly provided with a plurality of fourth mounting holes at a position higher than the bottom horizontal strip plate, and the mounting bolts are also used to pass through the fourth mounting holes and the preset mounting holes to achieve the connection between the bottom bracket and the position to be installed.

[0019] As a preferred technical solution of the present invention, the second mounting hole, the third mounting hole and the fourth mounting hole are all horizontally placed bar-shaped through holes.

During this process, the staff who fix the photovoltaic inverter box do not need to be subjected to high-intensity force for a long time, reducing the possibility of personnel fatigue causing installation efficiency to slow down, making the actual installation of the photovoltaic inverter box faster and more efficient.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] like Figure 1-4 As shown, the utility model provides a photovoltaic inverter mounting mechanism, comprising: a top mounting frame, a bottom bracket, a top mounting ear 1, a bottom mounting ear 2, and a plurality of mounting bolts 3;

[0031] like Figure 2 As shown, one end of the top mounting ear 1 is fixedly connected to the top side of the rear panel of the photovoltaic inverter 4 housing, and one end of the bottom mounting ear 2 is fixedly connected to the bottom side of the rear panel of the photovoltaic inverter 4 housing. The other end of the top mounting ear 1 and the other end of the bottom mounting ear 2 are respectively penetrated by a first mounting hole 5;

[0032] The top mounting frame includes a top horizontal strip 6; the bottom bracket includes a bottom horizontal strip 7 and a bottom supporting plate 8, and the bottom end of the bottom horizontal strip 7 is vertically fixedly connected to the top surface of the bottom supporting plate 8;

[0033] A plurality of second mounting holes 9 are evenly arranged on the top horizontal strip plate 6 and the bottom horizontal strip plate 7;

[0034] The top mounting ear 1 and the top horizontal strip 6, and the bottom mounting ear 2 and the bottom horizontal strip 7 are connected by mounting bolts 3 passing through the first mounting hole 5 and the second mounting hole 9, respectively;

[0035] The mounting bolt 3 is also used to pass through the second mounting hole 9 and the pre-set mounting hole at the position to be installed, so as to realize the installation connection between the top mounting frame and the bottom bracket at the position to be installed.

[0036] In the actual overall installation of the photovoltaic inverter 4, the outer casing of the photovoltaic inverter 4 needs to be installed on the wall or the bracket under the photovoltaic panel assembly. However, since the photovoltaic inverter 4 is heavy, there are certain requirements for the load-bearing capacity of the installation position. Therefore, the installation structure proposed in the present invention has made improvements to meet the above requirements. Its usage process and working principle are as follows: the top horizontal strip 6 and the bottom horizontal strip 7 can be installed by installing bolts 3, and they can be installed on a wall with pre-set mounting holes or a bracket rod, or other methods can be used to fix the top horizontal strip 6 and the bottom horizontal strip 7; then the photovoltaic inverter 4 box is moved as a whole to the top mounting frame and the bottom bracket position. Since the bottom horizontal strip 7 of the bottom bracket is fixedly connected to the bottom bracket 8, the photovoltaic inverter 4 box can be placed on top of the bottom bracket 8, and the bottom bracket is used for support and leverage, so that the staff can reduce the force and can align the first mounting hole 5 and the second mounting hole 9 more quickly and easily, which facilitates the subsequent installation of the photovoltaic inverter 4 box with bolts 3. During this process, the staff who fix the photovoltaic inverter 4 box do not need to be subjected to high-intensity force for a long time, reducing the possibility of slowing down the installation efficiency due to staff fatigue, making the actual installation of the photovoltaic inverter 4 box faster and more efficient.

[0037] As an embodiment of the present invention, Figure 4 As shown, a rear hook hanging ear 10 is provided on the top of the rear side of the top mounting ear 1, and the rear side of the hanging ear 10 is hung on the rear side of the top end of the top horizontal strip 6. When the photovoltaic inverter 4 box is installed, there is not only a supporting support at the bottom of the box, but also a hanging support at the top, which saves workers effort and facilitates practical and efficient installation.

[0038] As an embodiment of the present invention, Figure 1 and 3 As shown, the top mounting frame also includes a top back plate 11 and a top bottom plate 12. The bottom of the top horizontal strip 6 is fixedly connected vertically to the front side of the top bottom plate 12, and the rear side of the top bottom plate 12 is fixedly connected vertically to the rear side of the top back plate 11. The height of the top back plate 11 is higher than the height of the top horizontal strip 6. A parallel gap cavity 13 for accommodating the hanging ear 10 is provided between the top back plate 11 and the top horizontal strip 6; it can facilitate the hanging of the top mounting ear 1 on the top horizontal strip 6.

[0039] A plurality of third mounting holes 14 are evenly provided through the top back plate 11 at a position higher than the top horizontal strip 6 , and the mounting bolts 3 are also used to pass through the third mounting holes 14 and the preset mounting holes to connect the top mounting frame to the position to be installed.

[0040] The bottom bracket further includes a bottom back plate 15, the bottom end of which is fixedly connected to the rear side of the bottom support plate 8 in a vertical manner. The height of the bottom back plate 15 is higher than that of the bottom horizontal strip 7, and a parallel gap cavity 13 is also provided between the bottom back plate 15 and the bottom horizontal strip 7.

[0041] The bottom back plate 15 is evenly penetrated with a plurality of fourth mounting holes 16 at a position higher than the bottom horizontal strip 7. The mounting bolts 3 are also used to pass through the fourth mounting holes 16 and the preset mounting holes to connect the bottom bracket to the position to be installed.

[0042] When installed on a wall, the rear side of the outer box of the entire photovoltaic inverter 4 is very close to the wall, which is inconvenient for heat dissipation and the hanging ear 10. By providing the top back plate 11 and the bottom back plate 15, the entire installation mechanism can be more suitable for wall installation scenarios, so that the distance between the back of the outer box of the photovoltaic inverter 4 and the wall is increased, which is convenient for heat dissipation. A gap cavity 13 can also be formed on the rear side of the top of the top horizontal strip 6 to facilitate the hanging of the hanging ear 10, so that the photovoltaic inverter 4 can be supported and leveraged when installed, which is beneficial to improving the overall installation efficiency and the heat dissipation efficiency of the photovoltaic inverter 4.

[0043] As an embodiment of the present invention, the second mounting hole 9, the third mounting hole 14 and the fourth mounting hole 16 are all horizontal bar-shaped through holes, which facilitate the hole alignment of the photovoltaic inverter 4 during installation and can speed up the position determination of the photovoltaic inverter 4 during installation.

[0044] As an embodiment of the present invention, the top back panel 11 is provided with a fifth mounting hole at a position parallel to the second mounting hole 9 on the top horizontal strip 6, and the bottom back panel 15 is provided with a fifth mounting hole at a position parallel to the second mounting hole 9 on the bottom horizontal strip 7; when the installation position is a wall, the mounting bolt 3 is used to simultaneously pass through the fifth mounting hole of the top back panel 11 and the second mounting hole 9 of the top horizontal strip 6 and be screwed into the preset mounting hole to realize the installation connection between the top mounting bracket and the wall; the mounting bolt 3 is used to simultaneously pass through the fifth mounting hole of the bottom back panel 15 and the second mounting hole 9 of the bottom horizontal strip 7 and be screwed into the preset mounting hole to realize the installation connection between the bottom bracket and the wall. This embodiment is also specially designed for wall installation. When installing the bolt 3, the combination of a screw and a nut is generally required. However, in the wall installation scenario, the nut at the rear of the screw is inconvenient to install. Therefore, a hole is drilled in the installation wall to achieve long-distance screw-in installation of the screw. At this time, mounting holes are set at the top back plate 11 and the bottom back plate 15 at the top and bottom mounting ears 2, so that the mounting bolts 3 connecting the mounting ears can be screwed into the wall as deeply as possible, thereby enhancing the stability of the connection and ensuring the installation stability of the photovoltaic inverter 4.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
