Roof unpowered fan set for livestock-raising pigsty

Abstract

The invention relates to a roof unpowered fan set for a livestock-raising pigsty. The roof unpowered fan set comprises a wind resistance cover, rotary fans and unpowered fans and is characterized in that a device body is provided with a middle flat top, and six rotary fans are symmetrically arranged at the upper end of the middle flat top; each rotary fan comprises wind accumulation bowls and a rotary shaft; an electricity conversion and storage device is further arranged on one side of the top end of the middle flat top; lateral oblique tops are symmetrically arranged on two sides of the middle flat top; each unpowered fans are symmetrically arranged at the upper end of each lateral oblique top; air collecting tubes are fixedly arranged at the bottom ends of the lateral oblique tops, andthe upper ends of the air collecting tubes are communicated with the unpowered fans. The roof unpowered fan set has the advantages that three hollow semispherical-structured wind accumulation bowls are arranged at the top end of each rotary shaft in an annular arrayed manner, the semispherical structures are beneficial to wind accumulation and rotation, rotation speed is increased effectively by the three wind accumulation bowls arranged on each rotary shaft, and experiments show that wind power can be sufficiently utilized by the three wind accumulation bowls.

Description

technical field [0001] The invention relates to the technical field of animal husbandry and breeding equipment, in particular to a roof non-powered fan unit for animal husbandry and pig houses. Background technique [0002] Aquaculture is an extremely important link in the material exchange between humans and nature, and is one of the main components of agriculture. It is listed as the two pillars of agricultural production along with planting. With the continuous development of the economy and the improvement of people's living standards, in recent years, the breeding industry in various places has been adopting large-scale and standardized farming, and the characteristics of large-scale farming are intensive breeding, which has great impact on pig houses and poultry houses. Buildings are particularly important, especially facilities such as exhaust systems, all of which are powered by social power supply, so that there are problems of energy consumption and increased opera...
