Embodiment Construction

[0023] see Figure 1-Figure 6 , The invention includes devices such as a solar cooker, a Stirling machine, a flywheel, a drum gear coupling, an overrunning clutch, a vertical shaft fan, and a generator.

[0024] The solar cooker is a hemispherical spherical reflector, which is installed at the bottom of the thermal cylinder of the Stirling machine, and the focused solar energy heats the thermal cylinder of the Stirling machine to provide thermal energy for it, and the center of the spherical reflector is located in the thermal cylinder axis.

[0025] The Stirling engine is an external combustion engine with focused sunlight as a heat source, and its main structure includes a hot cylinder, a cold cylinder, a heat sink, a piston, a regenerator, a connecting rod, a crankshaft, and a sleeve. The heat sink is a thin copper concentric ring located on the cold cylinder, which is used to increase the heat dissipation efficiency of the cold cylinder. The regenerator is located in the...

Abstract

The invention discloses a wind energy and light energy combined power generation device which comprises main mechanisms such as a solar cooker, a Stirling engine, a flywheel, a drum gear coupler, overrun clutches, a vertical shaft fan and a power generator body. The wind and light combined power generator is characterized in that a power generation manner for utilizing the solar heat effect based on Stirling circulation is adopted, single-crystal-silicon and multi-crystal-silicon materials are completely replaced, production energy consumption is lowered, and pollution is reduced. A vertical shaft fan is used for replacing a wind wheel tower type power generator to overcome the defect that work cannot be done under strong wind, damage is not likely to happen, maintenance is easy, and the cost is low; a regenerator is additionally arranged in the Stirling engine so as to improve the utilization efficiency of heat energy, and the radiating efficiency is improved by additionally arranging a cooling fin on the outer portion of a cold air cylinder; the flywheel with the certain mass is used for storing and releasing angular kinetic energy to make the Stirling engine run more stably; and the problem that the rotating speeds of two power shafts are matched is solved through the overrun clutches.

Description

technical field [0001] The invention relates to a combined power generation device that simultaneously utilizes wind energy and light energy, and belongs to the technical field of wind energy light energy combined power generation. Background technique [0002] Social and economic development and progress require energy support, and the energy supply is mainly based on disposable fossil fuels. Nowadays, fossil fuels are increasingly scarce and environmental pollution is becoming more and more serious. Research on renewable, clean, and environmentally friendly green energy that can replace disposable energy, In particular, the application of clean energy power generation has become unstoppable. In view of the actual situation in the South my country Sea region of China, the energy needed for people's lives must be supplied by transporting gasoline and diesel from land, and the cost is relatively high. Therefore, taking advantage of the strong sunshine and high wind energy de...
