Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, in particular to a multi-angle photovoltaic tracking bracket. Background Art

[0002] Photovoltaic brackets are supporting structures for installing solar photovoltaic modules. They are usually composed of pillars, beams, connectors and other components. Different types of brackets can be selected according to different installation environments, such as ground brackets, roof brackets, etc. The main function of photovoltaic brackets is to fix solar panels and keep them at a certain tilt angle so as to receive sunlight to the greatest extent and convert it into electrical energy. At the same time, the brackets must be able to withstand the test of natural environments such as wind and rain to ensure the stable operation of the solar power generation system.

[0003] However, fixed photovoltaic mounts are set up at a fixed angle, which will cause the photovoltaic panel's power generation efficiency to decrease in different seasons and at sunrise and sunset. Tracking photovoltaic mounts can follow the sun's movement trajectory and adjust the angle to maximize light. Therefore, the power generation efficiency of tracking photovoltaic mounts is higher than that of fixed photovoltaic mounts. The currently commonly used tracking method is to use photoelectric sensors or GPS and other technologies to detect the sun's position in real time, so that the photovoltaic panels are always facing the sun. This can maximize the energy output of the photovoltaic system, but both the installation cost and maintenance cost of tracking photovoltaic mounts are high, which increases the total cost of the solar energy system and makes it difficult to use on a large scale. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is that the structure of the tracking photovoltaic bracket, including the installation cost and the maintenance cost, is relatively high, making the total cost of the solar energy system too high to be widely used over a large area.

[0008] A multi-angle photovoltaic tracking bracket comprises a base, a movable track is arranged on the base, a hydraulic cylinder assembly is arranged below the base, a hydraulic rod of the hydraulic cylinder assembly passes through the base and extends to the top of the base, a central axis is arranged at one end of the hydraulic rod of the hydraulic cylinder assembly, a photovoltaic inclined bracket is arranged on the movable track, one end of the photovoltaic inclined bracket is a connecting end, a connecting ring is arranged on the connecting end, the other end of the photovoltaic bracket is a movable end, the movable end is in an arc shape, and a movable pulley is arranged at the bottom of the movable end.

[0009] Furthermore, legs are provided at four corners of the bottom of the base, and reinforcing ribs are provided on the outer surfaces of the legs.

[0014] (III) Beneficial effects

[0015] The beneficial effects of the utility model are:

[0016] The photovoltaic bracket is connected through the central axis, and the hydraulic cylinder is used to drive it to change its angle. Compared with tracking methods such as photoelectric sensors and GPS, the cost is greatly reduced.

Although the accuracy is low, it can meet the requirements of multi-angle changes and low cost, and can be used over a large area. BRIEF DESCRIPTION OF THE DRAWINGS
