Abstract
Description
Technical Field
[0001] This utility model relates to the field of large-scale poultry house technology, specifically to an air inlet window. Background Technology
[0002] In enclosed poultry houses, ventilation is an important means of regulating the poultry environment. It can regulate oxygen concentration, remove harmful gases, and adjust negative pressure within the poultry house. As poultry grow, their daily requirements for suitable temperature, humidity, and ventilation vary. To meet the daily requirements for temperature, humidity, and minimum ventilation in the poultry house, the opening degree of ventilation windows varies, necessitating the periodic operation of fans for ventilation.
[0003] Currently, self-balancing ventilation windows on side walls are commonly used in livestock farms. These fans start under negative pressure, creating a pressure difference between the inside and outside, and the fan blades automatically balance (opening at a certain angle). Under the same pressure difference, the counterweight can be adjusted to control the opening angle of the fan blades. However, in actual use, because the pressure inside the shed cannot be precisely controlled, the fan blades often only open to their minimum or maximum angle. Furthermore, when there is no need for ventilation in the farm, the fan blades cannot close completely, resulting in air leakage. Utility Model Content
[0004] To address the shortcomings of existing technologies, an air inlet window is proposed, which solves the problem that in the aforementioned technologies, the fan blades can only be opened at their minimum or maximum angle, and the fan blades cannot be closed tightly when there is no ventilation requirement in the farm.
[0005] To achieve the above objectives, the present invention proposes the following technologies:
[0006] An air inlet window includes a frame and a window panel movably connected to the frame. The frame is provided with a limiting component for limiting the movable position of the window panel, and a sealing component for blocking the gap between the window panel and the frame to prevent air leakage when the window panel is closed.
[0007] Furthermore, the frame includes two side plates symmetrically arranged about the window panel, the window panel being rotatably connected between the two side plates via a pivot shaft, and the limiting component located on the side plates to fix the rotational opening angle of the window panel.
[0008] Furthermore, the limiting component includes a limiting post, which abuts against the window panel from below to fix the opening angle of the window panel, and the limiting post can slide back and forth on the side panel surface.
[0009] Furthermore, the limiting component also includes a guide slide rail, which is vertically disposed on the side plate surface. A groove is provided in the middle of the guide slide rail, and the limiting post is slidably connected in the groove.
[0010] Furthermore, the slide groove is provided with a plurality of slots distributed along the extension direction of the slide groove, and the end of the limiting post is provided with a locking block for engaging with the slots. The locking block engages with the slots to position the limiting post.
[0011] Furthermore, the frame also includes crossbeams disposed on the upper and lower sides of the window panel, the crossbeams being fixedly installed between the side panels on both sides, and sealing components being disposed on the crossbeams and the side panels to seal the window panel from all sides.
[0012] Furthermore, the sealing assembly includes a first wind deflector and a second wind deflector spaced apart on the side panel, the adapter shaft being located between the first wind deflector and the second wind deflector, and the first wind deflector and the second wind deflector respectively abutting against the outer and inner sides of the window panel to achieve sealing of the window panel edge.
[0013] Furthermore, the sealing assembly also includes a first wind deflector located below the crossbeam and a second wind deflector located above the crossbeam, the first wind deflector and the second wind deflector respectively abutting against the upper and lower sides of the window panel to achieve a seal.
[0014] Furthermore, the first wind deflector and the second wind deflector are respectively inclined, and a sealing groove is provided on the side of the first wind deflector near the window panel, and a sealing strip is installed in the sealing groove.
[0015] Compared with the prior art, the comprehensive effects brought about by this utility model include:
[0016] In this application, by setting a limiting component, the operator can adjust the limiting component to limit and fix different opening angles of the window panel according to the ventilation requirements. This, in conjunction with the fan in the poultry house, enables precise adjustment of the opening angle of the window panel. When the window panel needs to be closed, the limiting component ensures that the window panel is closed tightly. At the same time, the sealing component seals the four sides of the window panel with the frame, effectively preventing air leakage. Attached Figure Description

They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] like Figures 1 to 7 As shown, an air inlet window includes a frame 1 and a window panel 2 movably connected to the frame 1. The frame 1 is provided with a limiting component for limiting the movable position of the window panel 2, and a sealing component for blocking the gap between the window panel 2 and the frame 1 to prevent air leakage when the window panel 2 is closed.
[0028] By setting a limiting component, the operator can adjust the limiting component to limit and fix different opening angles of the window panel 2 according to the ventilation requirements. This, in conjunction with the fan in the poultry house, enables precise adjustment of the opening angle of the window panel 2. When the window panel 2 needs to be closed, the limiting component ensures that the window panel 2 is closed tightly. At the same time, the sealing component seals the four sides of the window panel 2 with the frame 1, effectively preventing air leakage.
[0029] In the air inlet window of this embodiment, the frame 1 includes two side plates 3 symmetrically arranged about the window panel 2. The window panel 2 is rotatably connected between the two side plates 3 through a connecting shaft. The limiting component is located on the side plate 3 to fix the rotation opening angle of the window panel 2.
[0030] Specifically, the window panel 2 is flipped between the side panels 3 via a connecting shaft to change the tilt angle of the window panel 2, thereby adjusting the size of the ventilation opening. A bending plate is set at the bottom of the window panel 2, and a counterweight is set on the bending plate to control the opening angle of the window panel 2.
[0031] The limiting component is located on the side panel 3. By changing the position of the limiting component, its contact position with the window panel 2 can be adjusted, thereby adjusting and fixing the opening angle of the window panel 2 between the side panels 3, and achieving precise control of different opening angles.
[0032] In the air inlet window of this embodiment, the limiting component includes a limiting post 4. The limiting post 4 abuts against the window panel 2 from below to fix the opening angle of the window panel 2. The limiting post 4 can slide back and forth on the surface of the side panel 3.
[0033] Specifically, the limiting post 4 is located on the inner side of the window panel 2, which facilitates the adjustment of the limiting post 4 from the inside. Adjusting the limiting post 4 to different heights allows it to support the window panel 2, thereby corresponding to different opening angles of the window panel 2, meeting different ventilation requirements, and improving the accuracy of window panel 2 adjustment.
[0034] In the air inlet window of this embodiment, the limiting component also includes a guide slide rail 5, which is arranged vertically on the surface of the side plate 3. A slide groove 6 is provided in the middle of the guide slide rail 5, and the limiting post 4 is slidably connected in the slide groove 6.
[0035] Specifically, a limiting post 4 is provided in the middle of the slide 6. The limiting post 4 is inserted into the slide 6 through the insertion interface. Then, the height of the limiting post 4 is adjusted up and down to fix the rotation angle of the window panel 2 at different positions.
[0036] Preferably, the limiting components are symmetrically arranged on the two side plates 3, and the two limiting posts 4 are supported from both sides of the window plate 2 to achieve stability through limiting.
[0037] In the air inlet window of this embodiment, the slide groove 6 is provided with a plurality of slots 7 distributed along the extension direction of the slide groove 6, and the end of the limiting post 4 is provided with a locking block 8 for engaging with the slots 7. The locking block 8 engages with the slots 7 to position the limiting post 4.
[0038] Specifically, a slot 7 and a block 8 are provided so that the block 8 can be engaged into the slot 7 by rotating the limiting post 4, thereby positioning the limiting post 4 in the slide groove 6, fixing the limiting post 4, and thus fixing the opening size of the window panel 2.
[0039] The design includes a slide groove 6 for inserting and removing the limiting post 4. The limiting post 4 can slide freely within the slide groove 6. When it slides to the corresponding position, the limiting post 4 can rotate 45 degrees within the slot 7, thereby fixing the limiting post 4 in place.
[0040] In this embodiment, there are three slots 7, which correspond to the closed position, the 70-degree open position, and the 90-degree open position of the window panel 2, respectively.
[0041] Specifically, the limiting post 4 includes a slider part and a handle part. The slider part includes a disc-shaped slider, the locking block 8 consists of two protrusions symmetrically arranged about the slider, and the locking groove 7 is an extension groove arranged on both sides of the slide groove 6 to accommodate the rotating locking block 8 to achieve locking.
[0042] Preferably, the handle of the limiting post 4 extends to one side to increase the contact area with the fingers, so that when the operator moves the limiting post 4 to a specific position for rotation according to ventilation requirements, a suitable gripping position can be found.
[0043] Preferably, the handle and slider of the limiting post 4 are at a certain angle (45 degrees). This is to allow sufficient space so that when the operator moves the limiting post 4 to a specific position for rotation according to ventilation requirements, such as... Figure 3 As shown, there is a certain space between the handle of the limiting post 4 and the window panel 2, allowing fingers to reach in and grab.
[0044] In addition, the handle of the limiting post 4 is wider at the top and narrower at the bottom, which can further increase the space between the limiting post 4 and the window panel 2.
[0045] In the air inlet window of this embodiment, the frame 1 also includes a crossbeam 9 disposed on the upper and lower sides of the window panel 2. The crossbeam 9 is fixedly installed between the side panels 3 on both sides. Sealing components are respectively disposed on the crossbeam 9 and the side panels 3 to seal the window panel 2 from all sides.
[0046] Specifically, after the window panel 2 is closed and limited by the limiting post 4, the sealing assembly seals the top, bottom, left, and right sides of the window panel 2, thereby achieving further sealing, preventing air leakage, and improving the sealing performance.
[0047] In the air inlet window of this embodiment, the sealing assembly includes a first wind deflector strip 10 and a second wind deflector strip 11 spaced apart on the side plate 3. The adapter shaft is located between the first wind deflector strip 10 and the second wind deflector strip 11. The first wind deflector strip 10 and the second wind deflector strip 11 abut against the outer and inner sides of the window plate 2 respectively to achieve sealing of the edge of the window plate 2.
[0048] Specifically, the first wind deflector 10 and the second wind deflector 11 are respectively inclined. The bottom of the first wind deflector 10 is provided with a transition groove. The two ends of the transition shaft on the window panel 2 are connected in the transition groove to realize the rotation setting of the window panel 2.
[0049] When the window panel 2 is closed, the top edge of the portion of the window panel 2 located on the upper side of the transition groove abuts against the first wind deflector 10 on the side panel 3, and the bottom edge of the portion located on the lower side of the transition groove abuts against the second wind deflector 11, thereby blocking the gaps on the left and right sides of the window panel 2 and preventing air leakage.
[0050] In the air inlet window of this embodiment, the sealing assembly further includes a first wind deflector 12 located below the crossbeam 9 and a second wind deflector 13 located above the crossbeam 9. The first wind deflector 12 and the second wind deflector 13 abut against the upper and lower sides of the window panel 2 respectively to achieve sealing.
[0051] When the window panel 2 is closed, its upper edge abuts against the first wind deflector 12 at the bottom of the upper beam 9, and its lower edge abuts against the second wind deflector 13 at the top of the lower beam 9. Through the cooperation of the wind deflector and the wind deflector strip, the window panel 2 and the frame 1 are sealed from the top, bottom and left and right. The four sides overlap and squeeze each other, effectively preventing air leakage and ensuring the effect after closing.
[0052] In the air inlet window of this embodiment, the first wind deflector 12 and the second wind deflector 13 are respectively inclined. The first wind deflector 12 is provided with a sealing groove 14 on the side near the window panel 2, and a sealing strip is installed in the sealing groove 14.
[0053] By providing a sealing groove 14 for installing a sealing strip below the crossbeam 9, when the window panel 2 is closed, the sealing strip and the sealing groove are squeezed against each other to prevent air leakage and improve the sealing effect.
