Description

Technical Field

[0001] The utility model relates to the field of photovoltaic construction, in particular to an installation fixture for a roof photovoltaic cable. Background Art

[0002] Photovoltaic, that is, a photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiant energy into electrical energy. The energy of the photovoltaic power generation system comes from the inexhaustible and renewable solar energy, which is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology; the photovoltaic power generation system is divided into an independent photovoltaic system and a grid-connected photovoltaic system. The photovoltaic power generation system is composed of equipment such as a solar cell array, a battery pack, a charge and discharge controller, an inverter, an AC power distribution cabinet, and a solar tracking control system; and the installation fixture for the roof photovoltaic cable is an installation fixture for clamping and installing the photovoltaic cable during roof photovoltaic construction.

[0003] Currently, the Chinese patent with the publication number CN117040407A discloses a fixture and a photovoltaic mounting rack, including a fixture for clamping and fixing a first workpiece and a second workpiece. A through hole is opened in the middle of the fixture along the Y-axis direction. Clamping mouths are respectively opened on both sides of the front end of the fixture. The two clamping mouths are symmetrically arranged about the center line of the through hole. A plurality of upper clamping teeth are arranged along the Y-axis direction on the upper wall of the clamping mouth. The upper clamping teeth clamp the upper surface of the first workpiece along the Z-axis direction. A plurality of lower clamping teeth are arranged along the Y-axis direction on the lower wall of the clamping mouth. The lower clamping teeth clamp the lower surface of the second workpiece along the Z-axis direction. The patent points out the defects of the prior art: Most traditional connectors are threaded fasteners such as bolts. When it is necessary to fixedly connect two workpieces, the bolt is passed through the two workpieces, and then a gasket and a nut are sleeved on the periphery of the bolt. For example, in a photovoltaic power plant, the photovoltaic mounting rack for carrying photovoltaic panels includes a side frame and purlins. The traditional installation method is to use bolts to pass through the side frame and purlins, and then sleeve a gasket and a nut on the periphery of the bolt. The installation steps of bolt connection are numerous, and the installation efficiency is low. After being eroded by sand, wind and rain for a long time, the bolt has the risk of rusting and loosening and failing, and a large amount of maintenance costs are required in the later stage; although this device solves the above deficiencies, at the same time, the following new defects appear in this device: 1. This device cannot install and clamp photovoltaic cables with different radii; 2. The manufacturing cost of this device is high and the installation efficiency is low. Summary of the Utility Model
