[0002] In poultry and livestock farming environments, ventilation deflectors are typically installed on the walls of the sheds to facilitate ventilation. However, due to their large size and length, after a period of use, issues such as panel deformation and inaccurate opening / closing strokes can lead to poor sealing at the wall contact point. This results in poor airtightness of the deflectors and uncontrollable insulation performance in the sheds. Utility Model Content

[0003] The present invention aims to solve the above problems and provides an adjustable ventilation device, the technical solution of which is as follows: An adjustable ventilation device includes a fixed plate, a guide plate, a sealing strip, a control rope, and a rope length adjustment device. The fixed plate has a ventilation opening, and the guide plate is positioned corresponding to the ventilation opening. The bottom of the guide plate is hinged to the fixed plate. When the top of the guide plate is away from the fixed plate, it is in an open state, forming a flow channel between the guide plate and the fixed plate, which communicates with the ventilation opening. The sealing strip wraps around the ventilation opening and is positioned between the guide plate and the fixed plate. When the top of the guide plate is pressed against the fixed plate, it is in a closed state, with its opposite sides abutting against the guide plate and the fixed plate, respectively. The rope length adjustment device is mounted on the fixed plate, and the two ends of the control rope are connected to the guide plate and the rope length adjustment device, respectively. The rope length adjustment device is used to adjust the length of the control rope.

[0018] Example 1 like Figures 1 to 3 As shown, an adjustable ventilation device includes a fixed plate 11, a guide plate 21, a sealing strip 3, a control rope 42, and a rope length adjustment device 43. The fixed plate 11 can also be a wall of a livestock shed, and the guide plate 21 is installed on the indoor side of the wall. Ventilation openings 12 are provided on the fixed plate 11, and the guide plate 21 is positioned corresponding to the ventilation openings 12. The bottom of the guide plate 21 is hinged to the fixed plate 11, and the top of the guide plate 21 can be opened and closed relative to the fixed plate 11. When the top of the guide plate 21 is away from the fixed plate 11, it is in the open state. At this time, a flow channel 22 is formed between the guide plate 21 and the fixed plate 11. Figure 3 As shown, the flow channel 22 is connected to the vent 12. The sealing strip 3 wraps around the vent 12 and is positioned between the flow guide plate 21 and the fixing plate 11. When the top of the flow guide plate 21 is pressed against the fixing plate 11, it is in a closed state. At this time, the sealing strip 3 abuts against the flow guide plate 21 and the fixing plate 11 on opposite sides, thereby achieving a tight fit between the flow guide plate 21 and the fixing plate 11. Preferably, the sealing strip 3 is fixedly installed on the side of the flow guide plate 21 facing the fixing plate 11, so that the sealing strip 3 can be replaced and installed synchronously with the flow guide plate 21. The rope length adjustment device 43 is mounted on the fixed plate 11. The two ends of the control rope 42 are respectively connected to the guide plate 21 and the rope length adjustment device 43. The rope length adjustment device 43 is used to adjust the length of the control rope 42, thereby controlling the opening and closing action and amplitude of the guide plate 21 by adjusting the length of the control rope 42. Specifically, the rope length adjustment device 43 includes a wheel axle, which is rotatably mounted on the fixed plate 11. The control rope 42 is wound around the wheel axle. The wheel axle is driven and rotated manually or automatically. The release length of the control rope 42 is adjusted by rotating the wheel axle. The automatic driving method includes motor drive or motor control via a gear mechanism or other transmission mechanism. There is one rope length adjustment device 43, which is simultaneously connected to each control rope 42, thereby simultaneously adjusting the length of each control rope 42, and thus simultaneously controlling the opening and closing actions of multiple guide plates 21 or multiple positions of the guide plates 21.

[0019] like Figure 1 and Figure 2 As shown, an adjustable locking device is also provided on the guide plate 21. The adjustable locking device includes a connecting plate 51, a hinge plate 52, a support bolt 53, and a rope connecting buckle 54. The connecting plate 51 is fixedly connected to the guide plate 21. The bottom of the hinge plate 52 is hinged to the connecting plate 51. The support bolt 53 passes through the hinge plate 52 and is threadedly connected to the hinge plate 52. The end of the support bolt 53 near the connecting plate 51 abuts against the connecting plate 51. The rope connecting buckle 54 is fixedly installed on the hinge plate 52, and one end of the control rope 42 is fixedly connected to the rope connecting buckle 54. By rotating the support bolt 53, the relative angle between the hinge plate 52 and the connecting plate 51 is adjusted, thereby adjusting the relative distance between the rope connecting buckle 54 and the guide plate 21, so as to adjust the tension of the control rope 42 at this point. This allows for adjustment of the tightness of the guide plate 21 when it is closed and the width of the guide channel 22 when it is open, based on the deformation of the sealing strip 3 and the guide plate 21 at this point.

[0020] Preferably, the adjustable locking device is installed on the top of the guide plate 21 for easy connection of the control rope 42. Multiple adjustable locking devices are installed on the guide plate 21, and the multiple adjustable locking devices are arranged horizontally and distributed at different positions on the guide plate 21, so as to control different positions of the guide plate 21 separately.

[0021] To facilitate the installation and routing of the control rope 42, a rope guide 41 is also included. The rope guide 41 is fixedly connected to the fixing plate 11, and the control rope 42 passes through the rope guide 41 and moves relative to the rope guide 41. The rope guide 41 can be correspondingly set with multiple adjustable locking devices, and also cooperate with guides for steering.

[0022] To improve structural strength and service life, the fixing plate 11 is made of aluminum alloy and the guide plate 21 is made of fiberglass.

[0023] Example 2 The difference between this embodiment and the above embodiments is that, Figure 4 and Figure 5 As shown, the sealing strip 3 is fixedly installed on the fixed plate 11, thereby keeping the sealing strip 3 away from the air inlet side of the outlet of the guide channel 22, avoiding air backflow at the outlet of the guide channel 22 due to the obstruction of the sealing strip 3, and ensuring that air can smoothly pass through the guide channel 22 and enter the breeding house when the guide plate 21 is opened to any angle, without affecting the ventilation effect.

[0024] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
