Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of animal husbandry, and in particular relates to a ventilation system without cold bridges suitable for ventilation of animal husbandry. Background Art
[0002] At present, the structure of the ventilation system in the livestock breeding industry still adopts the traditional inward-opening pull-cord type livestock deflector ventilation system, and the frames around the traditional ventilation system are composed of square tubes, and the frames are supported by a central support structure. The square tubes are generally iron tubes or aluminum alloy tubes. The square tube material itself is easy to rust, and the existing deflectors are generally made of aluminum alloy, stainless steel and other metals. With the change of seasons, the temperature difference between the inside and outside of the breeding shed is large. The breeding shed is easily affected by the temperature and cold bridges are easily generated. When the condensation water of the cold bridge adheres to the steel pipe frame, it is easy to rust and even corrode the steel pipe. It is also easy to disperse heat and the heat loss is large. In addition, the deflector needs to be installed on the central support structure with hinges and guides. The width of the central support is generally 120mm, and some can even reach 180mm. This will greatly reduce the ventilation area during ventilation and make the ventilation not smooth. Utility Model Content
[0003] The utility model provides a cold-bridge-free ventilation system suitable for livestock breeding ventilation. Through the linkage of PVC guide plates and a fiberglass frame control system, the ventilation area can be greatly increased, ensuring efficient ventilation in livestock breeding sheds without cold bridges and low heat loss.
