Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation component technology, and in particular to a pressure block anti-slip sleeve for the steel frame of a photovoltaic component. Background Technology

[0002] With the large-scale construction of photovoltaic power plants and the iterative upgrading of component materials, zinc-aluminum-magnesium coated steel frame photovoltaic modules have gradually been widely used in large-scale ground photovoltaic power plants and residential and industrial distributed photovoltaic power plants due to their excellent corrosion resistance, high structural strength and lower cost advantages, becoming one of the mainstream materials for photovoltaic module frames.

[0003] Existing zinc-aluminum-magnesium coated steel-edge photovoltaic modules have a high surface smoothness and extremely low coefficient of friction on the outer front side of the frame (commonly defined as the A-side in the industry) after coating treatment. Conventional photovoltaic module installation often uses aluminum alloy middle and edge clamps to directly press and fix them to the A-side of the frame. However, this conventional installation method has significant technical defects during actual installation and long-term operation and maintenance: First, the smooth surface of the zinc-aluminum-magnesium coating results in insufficient static friction between the aluminum alloy clamps and the frame, and between the aluminum alloy edge clamps and the frame. Under the influence of external forces such as strong outdoor wind loads, heavy snowfall, temperature cycling deformation, and installation disturbances, the clamps are prone to relative slippage with the module frame, leading to module slippage and displacement. Second, insecure module installation directly causes uneven stress on the photovoltaic panel, leading to the risk of microcracks and damage, while also affecting the overall flatness of the module array, reducing the power generation efficiency and operational stability of the photovoltaic power station. Third, slippage problems increase the workload of subsequent maintenance and tightening, raising the power station's operation and maintenance costs, and even posing a safety hazard of module detachment.

[0004] To address the aforementioned issues, existing technologies often employ methods such as increasing the clamping force of the pressure block and replacing it with a high-friction shim. However, increasing the clamping force can easily damage the zinc-aluminum-magnesium coating and compromise the integrity of the anti-corrosion layer. Ordinary shims are prone to aging and have poor fit, failing to fundamentally solve the problem of slippage between the smooth steel edge and the pressure block, and thus are unsuitable for the long-term outdoor stable operation requirements of photovoltaic power plants. Therefore, developing an installation structure that is simple in structure, easy to install, provides stable anti-slip performance, and does not damage the module frame, suitable for zinc-aluminum-magnesium steel-edged modules, has become an urgent technical problem to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure block anti-slip sleeve for the steel frame of photovoltaic modules, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressure block anti-slip sleeve for a photovoltaic module steel frame, comprising a steel structure frame with a zinc-aluminum-magnesium coating and an anti-slip sleeve, wherein the steel structure frame is configured as an S-shape, and the anti-slip sleeve is an integral bent steel structure, the anti-slip sleeve comprising a first fitting part and a second fitting part, wherein the first fitting part is provided with concave and convex serrations, the first fitting part and the second fitting part are respectively fitted to the upper end face and the side end face of the steel structure frame, the bottom of the anti-slip sleeve is snapped upwards against the upper wall inside the steel structure frame, and a pressure block assembly is provided on the top of the anti-slip sleeve.

[0007] As a further description of the above technical solution: both sides of the second bonding part are provided with outwardly bent lateral bending parts.

[0008] As a further description of the above technical solution: the pressure block assembly is a medium pressure block, which is pressed onto the anti-slip sleeves at the top of the two steel structure frames and locked to the lower purlins by bolt assembly.

[0009] As a further description of the above technical solution: the pressure block assembly is a side pressure block, which is pressed onto the anti-slip sleeve on the top of a steel structure frame and locked to the lower purlin by a bolt assembly.

[0010] Beneficial effects:

[0011] 1. By setting a steel anti-slip sleeve with concave and convex teeth and longitudinal limiting structure, indirect contact between the pressure block and the zinc-aluminum-magnesium coating is achieved. Combined with the elastic clamping characteristics of the anti-slip sleeve, the friction of the mating surface and the reliability of the limiting are greatly improved.

[0012] 2. The clamping force of the clamping block is fully applied to the steel protective sleeve body, avoiding direct squeezing and friction of the zinc-aluminum-magnesium coating by the clamping block. This prevents coating damage and peeling from the source, fully preserves the original anti-corrosion performance of the zinc-aluminum-magnesium frame, avoids the risk of frame corrosion caused by coating damage, and effectively extends the overall service life of photovoltaic modules and frames.

[0013] 3. By setting up an integrated anti-slip sleeve formed by a continuous stamping die, combined with its own elastic snap-fit ​​structure, fastening without fasteners can be achieved, without modifying existing facilities and construction processes, thus simplifying the installation steps.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.
