Description
Technical Field

Background
The online monitoring products of the power transmission line are applied outdoors, and most of the products supply power to the device in a mode of adding a photovoltaic panel to a battery. The types of outdoor towers can be mainly divided into iron towers and cement column towers according to appearance structures, different fixing supports are needed to be matched with angle irons of the iron towers and columns of the column towers on the online monitoring device, and extra accessory cost of the device is increased invisibly. In addition, since the capacity of the battery is limited, the charging efficiency of the battery by the photovoltaic panel directly affects the power supply performance of the device. The key factors for restricting the generating efficiency of the photovoltaic panel mainly include the shading of the shadow and the installation mode of the photovoltaic panel bracket.
The solar panel can cause 'hot spot effect' due to the partial shielding of shadow in the working process, the shielded partial solar panel can not provide power contribution and becomes energy consumption load in the solar panel, and simultaneously, the local temperature of the solar panel is increased, an overheated area can cause EVA (ethylene vinyl acetate) to accelerate aging and yellowing, so that the light transmittance of the area is reduced, the hot spot is further deteriorated, and the failure of the solar cell solar panel is aggravated. On the other hand, the principle of direct and diffuse separation of solar radiation from the total amount of solar radiation on an inclined plane can be used as follows: the total amount of solar radiation Ht on the inclined plane is composed of direct solar radiation Hbt sky scattering Hdt and ground reflection Hrt, namely: ht Hbt + Hdt + Hrt. Due to the fact that the installation inclination angles of the supports are different, the absorption accumulation amount of sunlight is different, and the accumulation difference of radiation amount causes the difference of power generation amount. Therefore, how to avoid and minimize the adverse effects is particularly important in the design concept of the photovoltaic panel bracket.
The existing photovoltaic panel fixing support only has single tower-shaped matching capability, has insufficient adaptability to different tower shapes, and increases development cost and assembly complexity; in addition, the angle adjusting capability of the existing photovoltaic panel support is single, shadows caused by blocking of other objects on a tower or a tower on the photovoltaic panel cannot be avoided flexibly, and the positions of solar radiation points and the positions of towers and other objects cannot be adjusted flexibly according to different seasons.
