Description

Technical Field

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

[0002] With the rapid development of building-integrated photovoltaics (BIPV) technology, rooftop photovoltaic systems have become an important form of urban renewable energy application. Traditional installation methods mostly rely on on-site welding or bolt fixing, which suffers from low installation efficiency and poor adaptability, especially for irregularly shaped roofs or locations requiring frequent maintenance. With the large-scale promotion of distributed photovoltaics, developing installation mechanisms that combine rapid installation, reliable fixing, and strong roof adaptability is of great significance for reducing system construction costs and increasing the photovoltaic penetration rate.

[0003] Existing rooftop photovoltaic (PV) installation mechanisms mainly consist of aluminum alloy guide rails, purlin connectors, and module clamping blocks. The guide rails are bolted to the pre-embedded base on the roof, and the PV panels are locked to the guide rails by edge clamping blocks. Wind-resistant designs rely on adding counterweights or mechanical anchoring that penetrates the roof; some systems use clamps to hold the roof ridge. The technical principle is to achieve physical fixation of the modules to the roof through rigid connections, with the load evenly transferred to the roof's load-bearing structure via the guide rails; however, the overall system lacks dynamic adjustment capabilities.

[0004] The most prominent drawback of existing installation mechanisms is that the modules and brackets are fixedly connected, meaning that if a single photovoltaic panel is damaged or malfunctions, the entire row of adjacent modules must be disassembled for replacement. For example, when a module exhibits a hot spot effect, maintenance personnel must sequentially remove the pressure blocks and loosen the guide rail bolts, an operation that requires working at height and takes more than 30 minutes. This structural defect significantly increases maintenance risks and system downtime, hindering the operational economics of photovoltaic systems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel rooftop photovoltaic installation mechanism, which aims to improve the problem of cumbersome installation and disassembly operations for photovoltaic panels.

[0006] To achieve the above objectives, the present invention provides the following technical solution: it includes a track one, a track two attached to the upper surface of the track one, an outer frame attached to the upper surface of the track two, and a quick-release assembly provided on the outer wall of the outer frame; The quick-release assembly includes a central pressure block, which is slidably connected in a groove inside the outer frame. A reinforcing block is fixedly connected to the outer wall of the central pressure block, and a second connecting post is slidably connected to the inner wall of the central pressure block. A fixing post is fixedly connected to the upper surface of the second connecting post, and a pull rod is slidably connected to the inner wall of the fixing post. A partition is fixedly connected to the outer wall of the pull rod, and springs one and two are provided on the outer wall of the partition. A ball is slidably connected to one end of the pull rod, and the pull rod is slidably connected to the inner wall of the second connecting post.

[0007] Furthermore, a second fixing plate is fixedly connected to the lower surface of the track, a first fixing block is fixedly connected to the outer wall of the second fixing plate, a first connecting column is rotatably connected to the inner wall of the first fixing block, a support block is rotatably connected to the outer wall of the first connecting column, a first fixing plate is fixedly connected to the outer wall of the support block, a second fixing block is fixedly connected to the upper surface of the first fixing plate, a base plate is fixedly connected to the outer wall of the second fixing block, a threaded rod is rotatably connected to the inner wall of the base plate, a slider is threadedly connected to the outer wall of the threaded rod, a connecting rod is fixedly connected to the inner wall of the slider, a pulley and a connecting rod are rotatably connected to the outer wall of the connecting rod, and a third fixing block is rotatably connected to one end of the connecting rod.

[0008] Furthermore, a front pressure block is slidably connected to the inner wall of the track, a photovoltaic panel is fixedly connected to the inner wall of the outer frame, and the reinforcing block is slidably connected in a groove opened in the outer wall of the outer frame.

[0009] Furthermore, a support column is fixedly connected to the lower surface of the fixing plate, and a cement block is fixedly connected to the outer wall of the support column.

[0010] Furthermore, an operating rod is fixedly connected to the outer wall of the threaded rod, and the pulley is slidably connected to the inner wall of the second fixed block.

[0011] Furthermore, the fixing block three is fixedly connected to the outer wall of the fixing plate two.

[0012] Furthermore, spring one and spring two are attached to the outer wall of the pull rod.

[0013] Furthermore, a base plate is attached to the outer wall of the fixing plate.

[0014] This utility model has the following beneficial effects: In this invention, to prevent the problem of difficult disassembly and maintenance caused by bolt fixing in traditional photovoltaic installations, an innovative spring pre-tensioning quick-release mechanism is adopted. The mechanism uses a pull rod linkage double spring system to drive the ball locking, and the medium pressure block is quickly released through a single pull action, so that the photovoltaic panel can be easily disassembled without stopping the machine, thus improving maintenance efficiency.

[0015] In this invention, to prevent the problem of low light-gathering efficiency caused by the difficulty in adjusting the angle of complex roofs, a threaded rod adjustment mechanism is used in conjunction with a slider-linkage transmission system. The displacement of the pulley within the track is controlled by rotating the operating rod to achieve the angle adjustment of the photovoltaic panel, ensuring the optimal light reception angle to adapt to different roof slopes.
