Problems solved by technology

The series tracking mechanism is simple in design, but limited by the rigidity of the material and structure, the traditional series two-axis solar concentrator tracking mechanism must use a vertical axis with a larger diameter to support the solar panel or the concentrator, which increases the cost of the mechanism

Abstract

The invention provides a support frame mechanism for a rigid and flexible parallel serial condenser rotating at two degrees of freedom. The support frame mechanism comprises a condenser, a movable platform, a rack, a passive rod, a first winch, a second winch, a third winch, a first steel wire rope, a second steel wire rope and a third steel wire rope. The moving platform is provided with a first rope fastener, a second rope fastener and a third rope fastener, the three winches are respectively connected with the three rope fasteners on the movable platform through the three steel wire ropes, the passive rod comprises a Hooke joint and a support rod, one end of the support rod is connected to the center of the movable platform through the Hooke joint, and the other end of the support rod is fixedly connected onto the rack. By driving the three winches to extend and retract the three steel wire ropes connected onto the movable platform, the condenser rotates at two degrees of freedom, so that the motion of tracking the sun is completed. The mechanism is simple in structure, high in reliability, symmetric, and low in production cost, and can be modularized.

Description

Technical field [0001] The invention relates to the field of energy, in particular to a two-degree-of-freedom rotating rigid-flexible hybrid mechanism that can be applied to support a concentrator to track the movement of the sun. Background technique [0002] Solar power generation is an effective method to solve the energy problems faced by mankind. Currently, solar power has two forms: photovoltaic power generation and solar thermal power generation. Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. Solar thermal power generation systems usually use solar concentrators to gather sunlight, and form a focused spot on a heat receiver located at the focal point / focus line of the concentrator, then generate heat energy, and finally convert it into electrical energy through related devices. Regardless of photovoltaic power generation or photothermal power generatio...
