Abstract

The invention provides a fixed adjustable solar support controlled by a pulley block. One end of a lower locating support is fixedly connected with the inside of one end of each supporting frame, and one end of an upper locating support is fixedly connected to a solar assembly bracket above the corresponding lower locating support; a rotary shaft of a rotary wheel is mounted outside the end part of one supporting frame, and a fixed pulley of the pulley block is further mounted on the supporting frame nearby the corresponding lower locating support; one end of a first steel cable is fixedly connected to the rotary wheel, and the other end of the first steel cable penetrates the pulley block, goes out of a movable pulley of the pulley block and is fixedly connected to the fixed pulley; a guiding fixed pulley is mounted at the end part of one supporting frame mounted on a middle supporting column, one end of a second steel cable is fixedly connected to the movable pulley of the pulley block, and the other end of the second steel cable winds around the fixed pulley and is then fixedly connected to one cross beam. The fixed adjustable solar support has the advantages that the pulley block is adopted to reduce the driving force by high power, the labor intensity during adjustment of an elevation angle can be effectively reduced in manners such as flexible adjustment, rigid fixation and the like, and equipment is convenient to maintain and repair.

Description

technical field

[0001] The invention belongs to the fields of solar photovoltaic power generation and solar thermal utilization, and relates to a fixed and adjustable solar bracket and a tracking device, in particular to a fixed and adjustable solar bracket controlled by a block of pulleys. Background technique

[0002] In order to overcome the reduction of power generation caused by fixed brackets due to seasonal changes, the fixed and adjustable type has been developed rapidly. But so far, either the sliding rod type or the screw rod type are used, but there are limitations such as large adjustment torque and the screw rod is easily affected by sand and dust. Contents of the invention

[0003] Based on the problems existing in the prior art, the present invention proposes a fixed and adjustable solar support controlled by a pulley block, which solves the technical problems of high labor intensity and inconvenient maintenance when adjusting the elevation angle of the exis...
