Air inlet window

Abstract

The invention relates to an air inlet window, and belongs to the technical field of ventilation devices. The air inlet window comprises a window body and a door plate, the door plate is formed by buckling an inner cover plate and an outer cover plate, the door plate can maintain good overall performance under the condition of large loads or temperature differences, and the problems of relative deformation and the like are avoided; and sealing bulges are arranged on the inner cover plate, and an anti-bird net is arranged in the window body, so that external birds can be effectively prevented from entering a room. According to the air inlet window, the sealing manner that the plane and the sealing bulges are combined is adopted, so that the sealing effect is remarkable, and assembling is easy; and meanwhile, the ventilation amount can be adjusted, so that the requirements of livestock and poultry for the ventilation amount in different seasons and different day ages are met.

Description

technical field [0001] The invention belongs to the technical field of ventilation devices, in particular to a wind inlet window. Background technique [0002] At present, the air intake window in the house for raising livestock and poultry generally consists of a window frame, a door panel, a sealing strip, a hinge and the like. Control the ventilation area by manually controlling the opening and closing angle of the door panel to achieve the purpose of indoor ventilation, which is time-consuming and labor-intensive. Moreover, as the seasons change and the age of livestock and poultry varies, the ventilation requirements are also different. Manual control cannot adjust the ventilation in time according to indoor needs. Quantity, can not guarantee a good indoor air environment. [0003] When the air inlet window is open, some flying birds may enter the room, which will affect the growth and development of indoor livestock and poultry, or damage indoor items. The anti-bird n...

Problems solved by technology

Control the ventilation area by manually controlling the opening and closing angle of the door panel to achieve the purpose of indoor ventilation, which is time-consuming and labor-intensive. Moreover, as the seasons change and the age of livestock and poultry varies, the ventilation requirements are also different. Manual control cannot adjust the ventilation in time according to indoor needs. Amount, can not guarantee a good indoor air environment

[0003] When the air inlet window is open, some flying birds may enter the room, affecting the growth and development of indoor livestock and poultry, or damaging indoor items. Bird-proof nets can solve the above problems

At present, the assembly of the anti-bird net and the window is generally connected by bolts. However, if the bolt is used, it is necessary to thicken the basic part of the anti-bird net and the form, and too much thickness will affect the ventilation effect of the small window itself.

At the same time, the door panels are generally made of plastic materials with a relatively thin thickness. The inner cover is in contact with the outside, and the outer cover is in contact with the room, resulting in different temperatures in the environments where the inner and outer covers are located, especially in Northeast China. In winter, there is a temperature difference of more than 60 degrees Celsius between the inner cover and the outer cover, resulting in a large difference in the deformation of the inner cover and the outer cover

Due to the thin thickness of the door panel, it cannot be bolted like metal

[0004] When the air inlet window is closed, the sealing strip can play a certain role in sealing, but there are still phenomena such as air leakage in the air inlet window, especially in winter in Northeast China, cold wind will enter the room through the gap between the door panel and the sealing strip, Due to the large temperature difference between indoor and outdoor, under the influence of cold wind, livestock and poultry are easy to get sick or even die in large numbers, causing huge economic losses
