Linkage tracking photovoltaic power station

Abstract

The invention discloses a linkage tracking photovoltaic power station which comprises single-shaft tracking photovoltaic power generation devices arranged in a plurality of rows and columns. The photovoltaic assemblies in the power generation devices are installed on a rectangular main beam through cross beams, and the rectangular main beam is installed in a segment-shaped inner ring body on a main beam bearing. A bearing fixing cover is mounted on a notch plane of the inner ring body, the inner ring body is rotationally supported on a bearing seat body with a semicircular upper part through a roller, and a bearing seat cover is mounted at the upper end of the bearing seat body; the lower part of the bearing seat body is supported on an adjustable support which can be arranged on a stand column in a left-right adjustable manner through an adjusting screw rod and an adjusting nut; liquid level meters which are communicated with one another through communicating pipes are mounted on the stand columns, and corresponding liquid level pointers are arranged on the bearing seat body. According to the invention, the centralized linkage tracking process of each single-axis tracking photovoltaic power generation device is flexible and light, and the installation and adjustment are convenient and fast, and the efficiency is high.

Description

technical field [0001] The present invention relates to a photovoltaic power station power generation equipment, in particular to a photovoltaic power station power generation equipment capable of centralized linkage tracking of the sun position. Background technique [0002] In the photovoltaic power station power generation equipment composed of several tracking photovoltaic power generation devices, the component brackets for installing photovoltaic modules in each tracking photovoltaic power generation device can be driven by the centralized linkage tracking drive device to change the installation angle position around a rotating shaft in a timely manner. The light-receiving surface of the photovoltaic module can be perpendicular to the sun's rays as much as possible, so as to receive more solar radiation, and the centralized linkage driving device that drives each tracking photovoltaic power generation device to perform tracking motion is connected with each tracking pho...

Problems solved by technology

[0003] The common tracking photovoltaic power generation device is a single-axis tracking photovoltaic power generation device. It installs photovoltaic modules on the main beam through several beams, and the main beam is supported on the column through the rotating shaft. connection, which requires the installation of a finely machined shaft on the main beam, which is troublesome to manufacture and process, and the shaft and the bearing must be inserted along the length direction during installation, the installation process is slow and the efficiency is low; in order to ensure the flexibility of the main beam rotation It is necessary to ensure that the rotating shafts between the main beam and each column are on the same axis, which must be ensured through on-site adjustments, during which not only the height of each column must be adjusted to ensure that the rotating shafts between the main beam and the columns are at the same level Position, but also adjust the left and right positions between each column and the main beam, so that the axis of the shaft between the main beam and the column is on the same vertical plane. Generally, the height of the shaft can be adjusted through the height of the column. The adjustment is only relatively cumbersome through the height adjustment of the column, but it will be very inconvenient to adjust the left and right positions by adjusting the position of the column, which will also make the installation and adjustment process very slow and inefficient

[0004] In the centralized linkage tracking photovoltaic power station equipment composed of several tracking photovoltaic power generation devices, it is not only necessary to ensure the flexibility of tracking adjustment of each tracking photovoltaic power generation device, but also to ensure the centralized linkage tracking drive of each tracking photovoltaic power generation In addition, it is also necessary to ensure the equal height of the main girder on which the linkage tracking drive arm is installed in each tracking photovoltaic power generation device. However, due to the lack of reference objects during the installation and adjustment process, it is impossible to determine the rotation axis between each main girder and several columns. Whether it is at the same level or not, the adjustment between a large number of columns and the main beam is based on experience and hand feeling, the installation will be more difficult and the installation efficiency will be lower
