Description

Yak barn

technical field

The utility model relates to the field of livestock breeding, in particular to a yak barn.

Background technique

At present, in the process of yak breeding, the yak greenhouse used generally includes a bottom surface, a wall body and a roof, and an air inlet is opened at the lower end of the wall facing south and north near the ground, and an air outlet is opened at the upper end. There are the following problems in the use of this simple cowshed: First, although the cowshed solves the problem of ventilation, the temperature is relatively low in high-altitude pastoral areas, especially in winter, when the temperature reaches minus 30 degrees Celsius , after the outside cold wind enters the cowshed from the air inlet at the lower end of the wall, on the one hand, it will greatly reduce the temperature inside the cowshed, making the cowshed unable to play the role of cold protection; on the other hand, the cold wind blows directly on the body of the yak , will make the yak often catch a cold or get frostbite, or even freeze to death. If the air inlet is closed, although the problem of cold protection is solved, the cowshed is not ventilated, the air does not circulate, and the temperature and humidity are high, which is easy to breed bacteria. And the concentration of toxic and harmful gases will increase, thus making the yaks susceptible to various infectious diseases and parasitic diseases; secondly, the existing simple cowsheds are relatively closed, and too many yaks are crowded together, which will cause the temperature in the cowshed to gradually decrease. However, there is no device that can adjust the temperature in the existing cowshed. Sometimes, there will be a large temperature difference between the inside and outside of the cowshed. In an environment with a lower temperature, the probability of yak disease will increase greatly; moreover, lighting devices are generally installed in the cowshed, and some equipment in the cowshed needs to be driven by the mains. However, the pastoral area is extensive. There are few people, the power facilities are relatively backward, and the power supply is not guaranteed. In addition, there is no special excrement cleaning channel in the existing cowshed, and there is no manure treatment system. After the yaks excrete in the cowshed, not only the internal environment is very poor, It affects the health of yaks, and the urine directly penetrates into the ground, causing serious pollution of soil and groundwater. In addition, the cow dung in the simple yak shed is difficult to clean up, and if it is directly dumped on the grassland, it will cause great damage to the pastoral environment.

By setting the exhaust holes 4 on the roof 3 and burying the geothermal heat exchange pipeline 5 under the bottom surface, one end of the geothermal heat exchange pipeline 5 extends to the outside of the wall 2 and communicates with the outside world, and the other end extends to the bottom surface 1 and communicates with the cowshed. Internal communication, the principle of the above ventilation system is to use two mixed ventilation methods of natural wind pressure ventilation and thermal pressure ventilation to realize the air circulation in the barn, and the wind pressure ventilation is to use the natural wind pressure to drive the outside air along the geothermal heat exchange pipeline 5 enter the barn, and then discharge from the roof vent 4 to form the house ventilation; and the principle of hot pressure ventilation is: the density of the air in the barn decreases after being heated, and gradually rises, and the air from the vents on the roof 4 discharge, forming a negative pressure in the house, so that the outside air is sucked into the barn along the heat exchange pipeline 5, thereby forming the air circulation in the barn, avoiding the increase of the concentration of toxic and harmful gases, and the cold air from the outside is heat exchanged by geothermal heat After the heat exchange of the pipeline 5, the temperature of the air entering the barn is relatively high, preventing the temperature in the barn from dropping sharply, thus preventing the yak from frostbite or even freezing to death. The contradiction between ventilation and cold protection.

In the above-mentioned embodiment, the geothermal heat exchange pipeline 5 can be implemented in a variety of ways, as long as the outside cold air can be heat-exchanged by geothermal heat to raise its temperature, as a preferred way is: the geothermal The heat exchange pipeline 5 includes an air inlet pipe 51, an air outlet pipe 52 in the house, and a plurality of heat exchange pipes 53 buried between the air inlet pipe 51 and the air outlet pipe 52 in the house, and the diameter of the heat exchange pipe 53 is less than The diameter of the air inlet pipe 51 and the air outlet pipe 52 in the house, the geothermal heat exchange pipeline 5 of this structure can effectively increase the geothermal heat exchange efficiency, and greatly increase the temperature of the air in the heat exchange pipe 53 . In order to allow more cold air to enter the geothermal heat exchange pipeline 5 for heat exchange and then enter the barn to improve the ventilation effect, the air inlet of the air inlet pipe 51 is set in a horn shape, which can increase the air intake.

In order to prevent external cold air from being poured into the barn along the exhaust hole 4 , an exhaust pipe 41 is arranged at the said exhaust hole 4 , and a wind cap 42 is arranged at the upper end of the exhaust pipe 41 .

Because there are more yaks in the cowshed, the temperature will gradually rise, and in summer, the temperature in the cowshed will be too high. In order to avoid excessive temperature in the barn, ventilation louvers 6 are provided on the body of wall 2, as shown in Figure 2, by adjusting the opening and closing of the louvers, the cold wind from the outside enters the barn to regulate the temperature in the barn.
