Description

Technical Field

[0001] This utility model relates to the technical field of ventilation devices for livestock farming, specifically to a ventilation window guide cover for livestock. Background Technology

[0002] Currently, livestock ventilation window airflow guiding mechanisms consist of two guide plate supports, a rotating shaft, and guide plates. During use, the angle of the guide plates needs to be adjusted in advance to allow airflow along them for ventilation. However, in the early stages of brooding, the opening angle of the air inlet is very small, and many guide plates cannot deliver fresh air to a greater distance. Furthermore, due to reflection and other factors, they frequently cause cold stress, posing a significant risk to livestock farming. Moreover, these guide plates are complex to adjust and require high installation standards. Limited by ventilation theory and farming experience, their applicability is limited, causing considerable trouble for farmers. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the existing technology and provide a ventilation window guide for livestock.

[0005] Furthermore, the forward projection of the intermediate busbar is rectangular, with an upward tilt angle of 20°.

[0006] Furthermore, the front view projection of the opening drainage plate is trapezoidal, and its upward horizontal tilt angle is greater than the tilt angle of the aforementioned intermediate confluence plate.

[0007] Furthermore, the connecting sleeve and the guide plate are integrally formed by sheet metal stamping and bending, and the whole is arranged symmetrically on the left and right with the center line of the middle confluence plate. The entire guide cover has a symmetrical structure.

[0008] Furthermore, the connecting sleeve includes an integrally formed front sidewall, left sidewall, upper sidewall, and right sidewall, and the width of the cavity formed therein is the same as the width of the ventilation window mentioned above.

[0009] Furthermore, the air deflector is fixed to the ventilation window by self-tapping screws passing through the corresponding connecting holes.

[0010] Compared with the prior art, the present invention has the following advantages: the present invention has a simple structure, is quick to install, requires no later debugging or operation, and has a wide range of applications; and the unique central air-gathering jet structure can effectively gather fresh air, ensuring that even when the ventilation window is opened at a very small angle, fresh air can flow to a more distant area through the central air-gathering jet area of ​​the guide hood, achieving an ideal ventilation effect.

[0018] It should be noted that in the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of the structural relationship of each component in this utility model and do not specifically mean that any component in this utility model must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as a limitation on this utility model.

[0019] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0021] like Figures 1 to 6 As shown, a ventilation window guide cover for livestock is installed above the ventilation window. It includes a connecting sleeve 1 and a guide plate 2. The connecting sleeve 1 and the guide plate 2 are integrally formed by sheet metal stamping and bending. The front projection of the connecting sleeve 1 is horizontally shaped like a "[". It includes a front side wall 11, a left side wall 14, an upper side wall 13, and a right side wall 12, which are fixedly connected to each other. The front side wall 11 is only provided in the upper half position. Its vertical width is consistent with the width of the upper window edge of the ventilation window. Multiple connecting through holes 3 for fixing are provided on the front side wall 11 of the connecting sleeve 1. The aforementioned guide plate 2 is disposed on the front side of the connecting sleeve 1, and includes a central confluence plate 21, a connecting transition plate 22, an opening guide plate 23, and a side plate 24. The central confluence plate 21 is located in the middle of the entire guide plate 2, extending upward and forward at an angle of 20°. The forward projection of the central confluence plate 21 is rectangular, forming a central air jet gathering area. The left and right sides of the central confluence plate 21 are provided with connecting transition plates 22 and opening guide plates 23, which are connected sequentially from back to front. The rear end of the connecting transition plate 22 is connected to the lower edge of the aforementioned front sidewall 11 and is inclined downward and forward. The front end of the connecting transition plate 22 is connected to the rear end of the opening guide plate 23, which is inclined upward and forward at an angle greater than the horizontal angle of the aforementioned central confluence plate 21. The side plates 24 are fixedly connected to the left and right ends of the connecting transition plates 22 and the opening guide plates 23 on both sides. The entire flow guide is symmetrically arranged on the left and right with the vertical plane where the central axis of the intermediate confluence plate 21 is located as the reference. The front view cross section of the entire connecting transition plate 22 is a gradually widening trapezoid, and the front view projection of the entire opening flow guide plate 23 is trapezoidal.

[0022] In use, the air deflector is installed on the upper end of the ventilation window. The width of the cavity enclosed by the connecting sleeve 1 is the same as the upper width of the ventilation window. It is installed and fixed to the ventilation window body by passing self-tapping screws through the corresponding connecting through holes 3. When the opening size of the ventilation window is within 25mm, the external fresh air only enters at the 65mm wide central converging plate 21 in the air deflector, forming a central air-gathering jet area. As the opening of the ventilation window gradually increases, the fresh air also gradually increases from the center to both sides under the action of the air deflector. When the opening of the ventilation window reaches 70mm or more, the width of the fresh air guided by the air deflector reaches its maximum. Throughout the opening and closing process, the initial airflow cross-section changes repeatedly from a small rectangle to a gradually widening trapezoid and then back to a trapezoid. This allows for variations in airflow volume and velocity based on the actual opening size of the ventilation window, reducing energy waste caused by excessive ventilation. Furthermore, the unique structural design ensures that when the ventilation window is small, fresh air travels along the roof and flows to the target area after being fully preheated, mitigating the risk of cold stress, reducing the risk of colds and gastrointestinal diseases in livestock and poultry, lowering medication costs, and increasing productivity.

[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
