Technical Field

[0002] An inverter is a device that can convert the variable DC voltage generated by photovoltaic solar panels into alternating current (AC) at the mains frequency. Therefore, a photovoltaic inverter is an indispensable component in a photovoltaic power generation system. When a photovoltaic inverter is used, it is usually installed on a corresponding bracket.

[0003] For example, an assembly bracket for a photovoltaic inverter with publication number CN210800628U includes a wall mount, a load-bearing groove and a safety frame assembly, wherein the load-bearing groove is connected to the rear side end of the photovoltaic inverter, with the notch of the load-bearing groove facing downward, and the main part of the wall mount is used for fixed installation on the wall, and the top of the wall mount is snapped into the load-bearing groove; the safety frame assembly includes a fixed part and a rotating part, the fixed part is connected to the bottom edge of the rear side end of the photovoltaic inverter, the rotating part is rotatably connected to the fixed part, and the rotating part can be translated relative to the two side directions of the fixed part respectively, and the bottom of the wall mount is detachably connected to the rotating part.

[0004] The above-mentioned prior art has the following technical problems: the existing inverter bracket can only limit the inverter when in use, because when the inverter is connected, there are usually more wire harnesses. When the wire harnesses are scattered, it is easy to cause adjacent wire harnesses to be intertwined and entangled. At the same time, some photovoltaic power generation systems are located in mountainous areas. When used in mountainous areas, although the inverter itself has rain and water resistance, it cannot effectively prevent falling rocks. The existing bracket is not convenient for buffering and protecting falling rocks.

[0005] Therefore, we propose an inverter bracket for a photovoltaic power generation system to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Example 1: Please refer to Figure 1-Figure 6The existing inverter bracket can only limit the inverter when in use. When the inverter is connected, there are usually more wire harnesses. When the wire harnesses are scattered, it is easy to cause the adjacent wire harnesses to be intertwined. In order to solve this technical problem, this embodiment discloses the following technical content;

[0037] An inverter bracket for a photovoltaic power generation system includes a positioning bracket 1, a photovoltaic inverter body 2 is installed on the side of the positioning bracket 1; a connecting frame 3 is fixedly connected to the back of the photovoltaic inverter body 2 by bolts, and the connecting frame 3 and the positioning bracket 1 are fixed to each other by a U-shaped clamp 4, a locking bolt 5 is installed on the connecting frame 3, and the locking bolt 5 passes through the side of the U-shaped clamp 4, and a sleeve nut 6 is screwed on the end of the locking bolt 5, and a shock-absorbing pad 7 is installed between the sleeve nut 6 and the connecting frame 3; a cluster tube 8 is installed at the lower end of the positioning bracket 1, and the cluster tube 8 is used to separate different wire harnesses, and the sleeve nut 6 threadedly connected to the end of the locking bolt 5 faces outward, and the shock-absorbing pad 7 between the sleeve nut 6 and the connecting frame 3 is set to an elastic rubber material. A plurality of cluster tubes 8 are evenly distributed on the positioning bracket 1 at equal intervals, and each cluster tube 8 is set to an "L"-shaped structure.

[0038] When installing the photovoltaic inverter body 2, place the photovoltaic inverter body 2 on the side of the positioning bracket 1, then use the U-shaped clamp 4 to cover the outside of the positioning bracket 1 and connect it with the connecting frame 3 on the back of the photovoltaic inverter body 2, then cover the shock-absorbing pad 7 on the outside of the locking bolt 5, and then screw the sleeve nut 6 on the end of the locking bolt 5, so as to complete the fixation of the photovoltaic inverter body 2 and the positioning bracket 1. Because the sleeve nut 6 is located on the outside of the end of the locking bolt 5, it is convenient to tighten and disassemble it with tools such as wrenches later. At the same time, a plurality of cluster tubes 8 are evenly distributed on the lower end of the positioning bracket 1. The plurality of cluster tubes 8 can separate and place a plurality of wire harnesses to avoid the phenomenon of interweaving and entanglement between the plurality of wire harnesses.

[0039] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. Some photovoltaic power generation systems are located in mountainous areas. When used in mountainous areas, although the inverter itself has rainproof and waterproof effects, it cannot effectively prevent falling rocks. The existing bracket is not convenient for buffering and protecting falling rocks. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1 , Figure 5 and Figure 6 As shown;

[0040] The positioning bracket 1 is fixedly connected to a fixed block 9 on one side facing the photovoltaic inverter body 2, and a protective top cover 10 is provided on the side of the fixed block 9, and the protective top cover 10 is connected to the fixed block 9 through a fixedly connected central axis 11, and a limiting screw 12 is connected to the side of the fixed block 9, and the lower end of the limiting screw 12 is screwed into the inside of the guide hole 13, and the guide hole 13 is opened in the circumference of the end of the central axis 11, and a pressure-resistant buffer component 14 for buffering and protecting against falling rocks is installed on the upper end of the protective top cover 10. Two guide holes 13 are provided in the circumference of the end of the central axis 11, and the angle between the two guide holes 13 is set to 90°, and the inner wall of the guide hole 13 is provided with an internal thread that matches the surface of the limiting screw 12, and the limiting screw 12 and the side of the fixed block 9 are threadedly connected. The pressure-resistant buffer component 14 includes a bottom plate 141, a vertical rod 142, an auxiliary spring 143, a pressure plate 144 and an elastic pad 145, and the bottom plate 141 is located above the protective top cover 10, the lower end side of the bottom plate 141 is fixedly connected with the vertical rod 142, and the vertical rod 142 is inserted through the protective top cover 10, the vertical rod 142 is connected to the protective top cover 10 through the auxiliary spring 143, and a pressure plate 144 is arranged above the bottom plate 141, and an elastic pad 145 is installed between the pressure plate 144 and the bottom plate 141. The vertical rod 142 and the bottom plate 141 are vertically distributed, and the vertical rod 142 forms an elastic telescopic structure through the auxiliary spring 143 and the protective top cover 10. The bottom plate 141 and the pressure plate 144 are parallelly distributed, and the bottom plate 141 and the pressure plate 144 are both bonded and fixed to the elastic pad 145.

[0041] When the photovoltaic inverter body 2 is installed and used, the protective top cover 10 is rotated on the fixing block 9. When the protective top cover 10 is rotated to a state perpendicular to the positioning bracket 1, the limiting screw 12 is screwed on the side of the fixing block 9 so that the lower end of the limiting screw 12 is screwed into the guide hole 13 on the central axis 11 on the side of the protective top cover 10, thereby completing the position fixing of the protective top cover 10 after unfolding. The setting of the protective top cover 10 can play a protective role against falling rocks when the photovoltaic inverter body 2 is used in a mountainous area. When the falling rocks contact the pressure plate 144 after falling, the gravity of the falling rocks can cause the elastic pad 145 to undergo elastic deformation, and the deformation of the elastic pad 145 can play a buffering role. If the force after the falling rocks fall is large, the force of the falling rocks can also cause the bottom plate 141 and the vertical rod 142 to move downward. After the vertical rod 142 moves, the auxiliary spring 143 can undergo elastic deformation, and the elastic deformation of the auxiliary spring 143 can further play a compressive buffering role.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
