Description

Technical Field

[0001] The utility model relates to the technical field of breeding ventilation, in particular to an adjustable breeding ventilation device. Background Art

[0002] Ventilation is a technology that uses natural or mechanical methods to allow wind to pass through the room or sealed environment without obstruction to create a hygienic, safe and suitable air environment. That is, mine ventilation engineering and technology are adopted to ensure the safety and health of miners working underground, to provide sufficient air that meets hygienic standards, to maintain the ambient temperature within the permitted range, and to discharge gas, coal dust, mine dust and harmful gases. Frequent ventilation can improve indoor air quality and is beneficial to health. Ventilation is a building environment control technology that controls the spread and harm of air pollutants and ensures the quality of indoor and outdoor air environments by means of ventilation dilution or ventilation exclusion. The ventilation system is a complete set of devices that realize the function of ventilation, including air inlets, exhaust vents, air supply ducts, fans, cooling and heating, filters, control systems and other ancillary equipment.

[0003] A livestock breeding intelligent ventilation device disclosed in the Chinese utility model patent application disclosure CN219305660U includes a ventilation frame, a controller is installed at the upper end of the ventilation frame, a waterproof mechanism is installed at the upper end of the controller, a fan is screwed to the inner wall of the ventilation frame, and an extension mechanism is attached to the inner wall of the ventilation frame. The livestock breeding intelligent ventilation device has a magnetic block to play a role of clamping and fixing the waterproof cover plate. When the device is used, the setting of the waterproof cover plate is convenient for waterproofing the controller and protecting the usability of the controller. The setting of the limit rod plays a role of threading and fixing the telescopic tube. When the device is used, the setting of the telescopic tube is convenient for adjusting the length of the device according to needs, which increases the usability of the device. The dustproof net is clamped and fixed by the connection block and the clamp block. When the device is used, the setting of the dustproof net is convenient for filtering and discharging foreign matter to prevent the inhalation of foreign matter from damaging the fan.

[0004] However, the device lacks ventilation and adjustment functions. When in use, if there is no need to replace the air inside the farm, but only to circulate the air inside and outside the farm, it will result in a waste of resources. Moreover, the device also lacks the function of replacing the air purification components. If dust and toxic substances enter the site during use, the livestock may become sick or even die.
