Problems solved by technology

The deficiencies in the use of this photothermal conversion device are: 1. The photothermal conversion device composed of multi-faceted concave mirrors occupies a large area. If a power station is built, a large land area is needed to place these concave mirror groups. It not only occupies the already scarce land in our country, but also makes the use cost high; 2. The concave mirror gathers light energy through reflection, and part of the light energy will be lost during the reflection process; 3. The investment cost is high

Description

Technical field: [0001] The invention relates to a power generating device, in particular to a convex lens concentrating solar power generating set which utilizes solar energy to generate power through heat conversion. Background technique: [0002] Existing devices that use solar energy to generate electricity through photothermal conversion are mainly composed of a photothermal conversion device, a steam turbine, and a generator. The photothermal conversion device is mainly composed of a concave mirror that focuses light energy and a heat absorbing device connected to it. Sunlight irradiates on the concave mirror and is reflected and concentrated to the focal point, forming a high temperature and supplying heat to the heat absorbing device. The deficiencies in the use of this photothermal conversion device are: 1. The photothermal conversion device composed of multi-faceted concave mirrors occupies a large area. If a power station is built, a large land area is needed to p...
