Description

Technical Field

[0001] This utility model belongs to the field of artificial turf technology, and in particular relates to an artificial turf for outdoor decoration. Background Technology

[0002] Artificial turf has been widely used in sports venues, garden landscapes, rooftop greening and courtyard decoration due to its advantages such as no watering required, strong weather resistance, low maintenance cost and long service life. However, traditional artificial turf has a single function, only having basic functions such as greening, decoration and sports fields, and cannot utilize the energy that is widely present in the environment, especially the huge surface solar radiation resources.

[0003] Because artificial turf occupies a large area, it has a large area exposed to sunlight, and its surface temperature is very high when used outdoors, reaching up to about 80 degrees Celsius. If thermoelectric power generation technology is used to create a potential difference between the high temperature of the turf and the low temperature below it to generate current, the turf can be given the ability to generate electricity. Therefore, designing artificial turf with thermoelectric power generation capability is a problem that needs to be solved by people in this field. Summary of the Invention

[0004] The purpose of this invention is to provide an artificial turf for outdoor decoration. By incorporating a flexible thermoelectric conversion layer and metal heat-conducting columns into the multi-layered structure of traditional turf, the artificial turf is successfully endowed with power generation capabilities. The heat collection layer is designed as the hot end to efficiently absorb and evenly distribute heat, while the metal heat-conducting columns, as the cold end, take full advantage of the constant temperature of the underground soil, providing a continuous and stable cold end temperature reference for the thermoelectric conversion layer. This creates and maintains an effective temperature difference between the upper and lower surfaces of the turf, significantly improving the efficiency and stability of thermoelectric conversion.
