Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module reinforcement technology, specifically a photovoltaic module wind load reinforcement device. Background Technology

[0002] During the installation of photovoltaic (PV) modules, workers often place multiple sandbags on the PV module supports to increase the overall weight of the PV modules, thereby ensuring that the PV modules will not be blown over by the wind. However, the existing PV module support frames have limited space and can only bear a limited load, resulting in weak overall wind resistance. As a result, they are prone to tipping over under strong winds, causing safety hazards. In view of this, a wind load reinforcement device for PV modules is proposed. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a wind load reinforcement device for photovoltaic modules, which can expand the load-bearing area and improve wind resistance.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a photovoltaic module wind load reinforcement device, the main body of which is installed on a support frame of the photovoltaic module, and sandbags are placed on the support frame. The main body includes at least three extension rods, each of which is located inside the support frame. A crossbar connects the three extension rods. A bolt is provided at the end of each extension rod. An abutment rod is rotatably connected inside the extension rod. A protrusion is provided at the end of the abutment rod. The end of each extension rod is rotatably connected to the support frame. The bolts are rotatably connected to the support frame and the abutment rod respectively. The crossbar is connected to the support frame.

[0005] In some embodiments, the side of the extension rod away from the support frame is at the same horizontal height as the bottom of the support frame after rotation.

[0006] In some embodiments, the protrusion is made of rubber.

[0007] In some embodiments, a redundant area is provided between the extension rod and the abutment rod.

[0008] In some embodiments, both the support frame and the extension rod are made of aluminum alloy.

[0009] In summary, this utility model has the following beneficial effects:

[0010] This utility model is equipped with reinforcement components. By cooperating with the extension rod and the abutment rod, it ensures a stable connection between the extension rod and the support frame. The extension rod increases the overall area for bearing the weight of the sandbag, thereby increasing the overall weight and wind resistance. In addition to using bolts to connect the extension rod to the support frame for storage, bolts can also be used to connect the extension rod to the ground, further strengthening the overall wind resistance.

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] See Figure 1-3 A wind load reinforcement device for photovoltaic modules includes a main body 3 mounted on a support frame 1 of a photovoltaic module 2. Sandbags are placed on the support frame 1. The main body 3 includes at least three extension rods 31, each of which is located inside the support frame 1. A crossbar 32 connects the three extension rods 31. A bolt 33 is provided at the end of each extension rod 31. An abutment rod 311 is rotatably connected inside the extension rod 31. A protruding rod 312 is provided at the end of the abutment rod 311. The end of each extension rod 31 is rotatably connected to the support frame 1. The bolts 33 are rotatably connected to the support frame 1 and the abutment rod 311 respectively. The crossbar 32 is connected to the support frame 1. In use, the operator first removes the bolts 33 from the three extension rods 31, then flips the three extension rods 31 off the support frame 1 using the crossbar 32, so that the three extension rods 31 are close to the ground. Then, the abutment rods 311 on each extension rod 31 are rotated to abut against the support frame 1, thereby fixing the extension rods 31 to the support frame 1 through the abutment rods 311. After that, the removed bolts 33 are used to connect the extension rods 31 to the ground. Finally, sandbags are placed on the support frame 1 and the extension rods 31 to increase the overall load, thereby reinforcing the photovoltaic module 2 against wind.

[0019] In some embodiments, the side of the extension rod 31 away from the support frame 1 is at the same horizontal height as the bottom of the support frame 1 after rotation. This ensures that the extension rod 31 and the support frame 1 are both close to the ground at the same time, thereby preventing the front of the support frame 1 from tilting up after the operator places sandbags on the extension rod 31, which could cause the support frame 1 to be blown up in the wind.

[0020] In some embodiments, the protruding rod 312 is made of rubber. This increases the frictional strength between the protruding rod 312 and the support frame 1, making the contact rod 311 more stable when it contacts the support frame 1, and ensuring the reinforcement of the support frame 1 by the extension rod 31.

[0021] In some embodiments, a redundancy area 313 is provided between the extension rod 31 and the abutment rod 311. The redundancy area 313 ensures that when the operator places the sandbag on the abutment rod 311, there is enough space for the abutment rod 311 to rotate downward under the pressure of the sandbag, so as not to be blocked by the extension rod 31 and cause the abutment rod 311 to break.

[0022] In some embodiments, both the support frame 1 and the extension rod 31 are made of aluminum alloy. This ensures the sturdiness of the support frame 1 and the extension rod 31, preventing them from being broken by sandbags and affecting the fixation of the photovoltaic module 2.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
