A motor gear rack driving mechanism is arranged on one side of a reflector, a heat collector is arranged above the reflector, a reflective piece is arranged on a reflective piece fixing support, a rotary shaft and a bearing and a bearing seat are arranged at two ends of the reflective piece fixing support respectively, the reflective piece fixing support provided with the rotary shaft, the bearing and the bearing seat is horizontally fixed on a foundation, an actuator is connected with an inclined gear which is meshed with a rack and connected with one end of the reflective piece fixing support, and a heat collecting pipe is connected with a heat insulating cavity which is arranged on a fixing support which is fixedly arranged on the foundation. The solar linear light condensing and heat collecting device is simple in processing process and capable of being quickly mounted, realizes high-power light condensing and heat collecting and is capable of being horizontally arranged, high in wind resistance, free of shadow sheltering and high in land utilization rate.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar linear concentrating heat collection device. Background technique [0002] Solar thermal power generation is to gather sunlight into a heat collector, and the heat in the heat collector is replaced by a heat conductor, and then a high-temperature and high-pressure steam is generated through a heat exchanger, and the steam drives a steam turbine to generate electricity. As a new power generation technology, it has been initially applied abroad. A large number of studies have shown that solar thermal power generation can be combined with traditional thermal power generation technology, with low cost and stable system power generation, and can be used as a new type of clean energy. [0003] The solar linear concentrating heat collection device mainly includes a linear reflector system and a linear heat collector. The linear reflector system includes dozens of linear ...

AI Technical Summary

Problems solved by technology

The trough heat collector uses arc-shaped reflectors to reflect sunlight to the focal point. The arc-shaped reflectors are difficult to process and have low focusing multiples; the tower heat collectors install the heat collector on the top of the tower, and the Hundreds of flat mirrors are installed on the solar dual-axis tracker to track the sun and focus the sunlight reflection on the heat collector at the same time. Each tracker requires a set of independent program control; the dish heat collector is installed on the solar dual-axis tracker through the reflector, the reflector forms a spherical surface, and emits sunlight to the focal point. The focusing factor is medium, but the heat collection The tracker must rotate with the tracker, so a part of the thermal pipeline must also rotate with the tracker, resulting in difficulty in laying the thermal pipeline and prone to major safety accidents such as breakage and leakage of high-temperature heat transfer liquid.
