Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component bracket openings, in particular to a photovoltaic component bracket opening device. Background Art

[0002] During the installation of a solar photovoltaic power generation system, the PV module brackets typically require bolt mounting holes, and the various bracket components are secured together using bolts. In mountainous photovoltaic environments, brackets are often installed following the slope. This can lead to misalignment of the bolt interfaces between components due to the angle of the bracket during installation, or even to the point where no bolt interfaces are available. To address this issue, PV module brackets are designed with multiple opening locations in mind. However, due to the complexity of mountain photovoltaic project environments and the limited number of openings required for materials, additional holes are often ineffective, and frequent openings are still required on site, reducing construction efficiency and increasing costs.

[0003] Currently, workers typically use a handheld electric drill to drill holes on-site. However, due to the high hardness of the support material, the drill is difficult to locate and prone to slipping during drilling, resulting in low drilling efficiency and increased construction costs. Therefore, a photovoltaic module support hole drilling device is urgently needed to address these technical issues. Utility Model Content

[0020] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a photovoltaic module bracket hole opening device of the present invention in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, a photovoltaic module support hole drilling device of the present invention includes a hand drill 1, a casing 2, a transmission shaft tube 3, a support frame 4 and a drill bit 5. The support frame 4 is used to support the drill bit 5 and the material to be drilled. The front end of the transmission shaft tube 3 is connected to the support frame 4 by a threaded connection. The threaded connection between the support frame 4 and the transmission shaft tube 3 makes it easy to replace the support frame with different sizes to adapt to different components of the photovoltaic module support. The support frame 4 includes an inverted U-shaped limiter 41, which can be clamped on the purlin C-shaped steel. The lower end of one side of the limiter 41 is provided with a connecting hole connected to the transmission shaft tube 3. The drill bit 5 is arranged in the connecting hole. The lower end of the other side of the limiter 41 is provided with a clamping portion 42 extending in the direction of the drill bit 5. The end of the clamping portion 42 is provided with a gap at a certain distance from the connecting hole, and the corresponding connecting hole is provided with a countersunk hole that can accommodate the drill bit 5.

[0022] The rear end of the drive shaft tube 3 is securely connected to the hand drill 1 via a sleeve 2. The sleeve 2 is made of metal and is threadedly connected to the hand drill 1. The sleeve 2 is then slidably connected to the drive shaft tube 3. A fixed drive shaft 31 and a linkage shaft 32 are disposed within the drive shaft tube 3. The rear end of the drive shaft 31 is in driving connection with the output shaft of the hand drill 1. The front end of the drive shaft 31 is connected to the rear end of the linkage shaft 32. A support sleeve 33 is sleeved on the linkage shaft 32. A spring 34 is sleeved on the front end of the linkage shaft 32. The two ends of the spring 34 respectively abut against the support sleeve 33 and the front end of the drive shaft tube 3. The front end of the linkage shaft 32 is connected to the drill bit 5.

[0023] In this embodiment, the output shaft end of the hand drill 1 is an internal hexagonal type, and the end of the transmission shaft 31 is an external hexagonal type. The transmission shaft 31 is connected to the linkage shaft 32 by a threaded connection, and the connection port is coated with lubricating oil. The rear end of the linkage shaft 32 is sleeved with a slider 35 fixed to the transmission shaft tube 3. The center of the slider 35 is provided with a through hole for the axial movement of the linkage shaft 32 and the transmission shaft 31. The slider 35 is made of metal and its function is to support the linkage shaft 32 and prevent the linkage shaft 32 from shaking during the rotation of the transmission shaft 31. The rear end of the linkage shaft 32 is provided with a blocking portion extending circumferentially. The front end of the through hole of the slider 35 is narrowed to prevent the blocking portion from passing through, thereby preventing the linkage shaft 32 from being unable to return due to excessive travel. A large amount of lubricating oil is coated inside the transmission shaft tube 3. The front end of the linkage shaft 32 is detachably connected to the drill bit 5.

[0024] The hand drill 1 provides power, enabling quick and efficient drilling of surfaces in materials of varying hardness. The drill bit 5 can be designed and applied based on actual dimensions, adapting to varying drilling requirements and making the device more convenient and versatile to use. The drive shaft tube 3 is connected to the hand drill via the sleeve 2, allowing the hand drill 1 to be replaced with a different power source to accommodate different materials, thus enhancing the adaptability of the drilling device.

[0025] The present invention provides a photovoltaic module support hole drilling device, which combines a hand drill 1, a transmission shaft tube 3, a support frame 4, and a drill bit 5. When drilling, the surface of the support to be drilled is inserted into the gap of the support frame 4 and perpendicular to the drill bit 5. The hand drill 1 is started, and the transmission shaft 31 drives the drill bit 5 through the linkage shaft 32 under the drive of the hand drill 1 to drill a hole in the photovoltaic module support surface. After drilling is completed, the linkage shaft 32 and the transmission shaft 31 are reset under the action of the spring 34. The powerful power of the hand drill 1 can effectively drill holes in the surface of high-hardness materials; the design diversity of the drill bit 5 can meet various drilling technical requirements by replacing different drill bits 5, thereby improving the flexibility of the drilling operation; the use of the support frame 4 can accurately locate the drilling position and prevent the hole position from slipping during the drilling process, thereby improving the efficiency of drilling.
