Description

Technical Field

[0001] The invention relates to the field of solar energy, and in particular to a trough type solar reflector detection device and a detection method thereof. Background Art

[0002] The growth of all things on Earth depends on the existence of the sun. The sun provides us with a huge source of energy. Most of the energy on Earth also comes from the sun. For example, fossil energy such as oil and coal are energy formed by the continuous growth of plants and animals in the past by absorbing solar energy. Later, these plants and animals were buried under the soil. This is actually a form of solar energy conversion and storage, and it is still being mined and used by humans today.

[0003] The potential for the development and utilization of solar energy is quite huge. According to statistics, the total energy used by people around the world in a year is only equivalent to tens of thousands of the energy radiated to the earth by the sun. In the future when fossil energy is about to be exhausted, solar energy will bring new vitality to mankind in terms of future energy.

[0004] The utilization of solar energy in medium and high temperature, especially thermal power generation technology, has developed rapidly. More and more temperature-raising trough DSG solar thermal power generation systems have begun to be built or are about to be put into operation. As the core equipment of the trough solar reflector, whether the installation accuracy of its parabola can meet its design requirements plays a vital role in the utilization efficiency of solar energy. How to detect its parabola is particularly important. The traditional detection method consumes a lot of manpower through manual measurement and calculation, and the measurement accuracy is not high. The existing detection equipment is either bulky, not accurate enough, or not versatile enough.
