Description

Green energy-saving environment-friendly pig house with changeable ventilation mode
Technical Field
The invention relates to the technical field of breeding buildings, in particular to a green energy-saving environment-friendly pigsty with a changeable ventilation mode.
Background
The modern pigsty is developed in a large-scale and intensive live pig breeding mode, wherein the ventilation design of the pigsty is a marking factor for measuring the modern pigsty, the environment quality in the pigsty is directly determined, and the poor pigsty environment can cause the immunity of pigs to be reduced to induce the diseases of the pigs, so that the live pig breeding level is influenced. Therefore, the correct regulation of the environmental factors such as the wind speed, the temperature, the relative humidity and the like in the pigsty is particularly important, the environmental quality condition in the pigsty can be effectively improved, a proper growth environment is provided for the pigs, and the pigs can fully exert the genetic and nutritional advantages of the pigs so as to improve the feeding efficiency.
The existing pigsty adopts a single non-changeable ventilation mode, and cannot provide the most suitable growth environment for pigs under the internal and external environments of different pigsties. For example, when the pig house needs high-strength ventilation cooling in hot days, the temperature in the pig house can be quickly reduced by the horizontal ventilation mode, but when the ventilation volume is reduced due to heat preservation in cold days, the air quality in the pig house which is uniform and excellent cannot be guaranteed by the horizontal ventilation mode, the air quality in the pig house which is close to one side of the air inlet is good, but the air quality in the pig house which is close to one side of the air outlet is difficult to reach the standard, because the air which is breathed by the pig which is close to one side of the air outlet is discharged when the pig which is close to one side of the air inlet breathes. It is for this reason that outbreaks occur and that piggeries in horizontal ventilation mode are more susceptible to the spread of pathogens. In contrast, the vertical ventilation mode is that fresh air enters the pigsty and then vertically passes through the pig housing area, so that the air circulation among pigs is reduced, the disease transmission is slowed down, and the fresh air can be uniformly distributed to each pig. However, when the pigsty needs high-intensity ventilation and cooling in hot days, the cooling effect is not good due to the fact that the air speed is too low in the vertical ventilation mode.
Based on this, this design provides a ventilation mode changeable green energy-concerving and environment-protective type pig house.
