Problems solved by technology
[0003] However, the fixed design of the support frame of the existing dish-type concentrating solar power generation device cannot rotate with the movement of the sun, resulting in a decrease in the utilization rate of solar energy, resulting in insufficient heating of the working medium of the external combustion engine, resulting in a decrease in power generation efficiency, and the existing The concentrating solar power generation device does not have a corresponding reflector cleaning device, which will cause the surface of the reflector to be contaminated with dust during long-term use, resulting in a decrease in reflective efficiency, resulting in a decrease in power generation efficiency

The invention relates to the technical field of external combustion engines, and discloses a dish-type concentrating solar power generation device utilizing external combustion engines to generate electricity. For a water pump, a motor is fixedly connected to the inside of the support seat, a drive wheel is fixedly connected to the outside of the motor, a transmission belt is movably connected to the outside of the drive wheel, and an adjustment gear is fixedly connected to the outside of the drive wheel. The outer meshing of the gear is connected with a rack, and the outer part of the rack is fixedly connected with a dish-shaped frame, and the bottom of the dish-shaped frame is movably connected with a guide wheel. The combination of the shape frame and the adjuster can achieve the effect of automatically adjusting the rotation of the dish frame, so that the dish frame and the reflector can always maintain the best effect of concentrating light, thereby effectively ensuring the efficiency of power generation.
Description
technical field [0001] The invention relates to the technical field of external combustion engines, in particular to a dish-type concentrating solar power generation device using external combustion engines to generate electricity. Background technique [0002] The external combustion engine is a kind of heat engine that uses fuel combustion to heat the circulating working medium (such as the high-temperature and high-pressure water vapor generated by the steam engine heating the water in the boiler to the inside of the machine) to convert heat energy into mechanical energy. It is often used in concentrated solar power generation. The basic principle is to use a parabolic reflector to gather light onto the heat-absorbing tube of the external combustion engine filled with working fluid, and then transport the heated working fluid to the heat exchanger, where the heat heats the circulating water to generate water vapor and drive The turbine drives the connected generator to ru...
