Description

Technical Field

[0001] This utility model relates to the field of ventilation window technology, and in particular to a ventilation window for sheds. Background Technology

[0002] Ventilation windows in livestock sheds are devices specifically designed to improve the livestock farming environment. Their main purpose is to improve the living conditions of animals, reduce the spread of diseases, and increase production efficiency by optimizing air circulation.

[0003] Existing ventilation windows are often equipped with cleaning mechanisms to facilitate the removal of cobwebs and debris trapped in the ventilation channels. However, these ventilation windows lack a mechanism that can directly drive the cleaning mechanism from a low position on the ground. This means that when clearing blockages in the ventilation channels, it is necessary to climb up to drive the cleaning mechanism, which is cumbersome, inconvenient, and less safe. Utility Model Content

[0004] In view of this, the present invention provides a shed ventilation window to solve the problem that when cleaning the ventilation channel, it is necessary to climb up to drive the cleaning mechanism, which is cumbersome to operate and has low safety.

[0005] The technical solution proposed by this utility model is: a ventilation window for a shed, specifically including: a window frame, wherein a row of horizontal bracing plates arranged at equal intervals in the upper and lower parts are fixed inside the window frame, and an arc-shaped windbreak plate is welded to the middle position of the horizontal bracing plates in the height direction;

[0006] A vertical slide rod is slidably installed on the bottommost horizontal support plate; a vertical positioning shaft is welded to a narrow side of a vertical side plate of the window frame, and a bushing is slidably installed on the vertical positioning shaft; a connecting rod is rotatably connected between the bushing and the bottom part of the vertical slide rod; a downward pulling rope and an upward pulling rope are connected to the bushing; two short positioning shafts are symmetrically welded at the two corners at the top of the window frame, and two guide wheels are rotatably installed on the two short positioning shafts; the tail end of the upward pulling rope passes through the two guide wheels in sequence and is pulled to the bottom of the window frame; cleaning shafts are welded on the vertical slide rod at equal intervals, and ventilation grooves are formed between every two horizontal support plates and between the upper and lower horizontal support plates and the upper and lower side plates of the window frame, with a row of cleaning shafts arranged in a row of ventilation grooves.

[0007] Furthermore, the vertical sliding rod is located inside the window frame, and two L-shaped limiting plates are symmetrically welded to the bottom side of the vertical sliding rod. The two L-shaped limiting plates slide in cooperation with the long strips at the upper and lower ends of the bottom horizontal support plate.

[0008] Furthermore, an annular guide rope groove is provided on the outer periphery of the guide wheel, through which the pull rope is guided.

[0009] Furthermore, the ends of the pull ropes at both locations are connected to rings.

[0010] Furthermore, an arc-shaped baffle is welded onto the positioning short shaft, the arc-shaped baffle being close to the outer periphery of the guide wheel and covering the annular guide rope groove.

[0011] Furthermore, a U-shaped mounting frame is welded to the window frame below the positioning short axis. A vertical insertion shaft, which is positioned by spring push, is slidably mounted through the opening of the U-shaped mounting frame. The protruding part at the top of the vertical insertion shaft is inserted and engaged with the protruding part at the beginning of the positioning short axis.

[0012] A limiting ring is welded and fitted onto the positioning short shaft, and the guide wheel is positioned between the limiting ring and the top protruding part of the vertical insertion shaft.

[0013] Furthermore, the guide wheel is installed with the positioning short shaft through a sliding fit.

[0014] The ventilation window for sheds provided by this utility model has the following beneficial effects:

[0015] 1. When the vertical sliding rod slides back and forth along the bottom horizontal support plate, a row of cleaning pins on it can be used to scrape and remove the spider webs and debris trapped and accumulated by the spider webs in a row of ventilation slots, thus clearing and unblocking the ventilation slots.

[0016] Second, since the ends of both pull ropes are suspended below the window frame and have a certain suspension length, workers only need to stand on the ground at a low position to alternately pull the pull ropes to drive the shaft sleeve to slide up or down, controlling the vertical slide rod and a row of cleaning levers to slide back and forth, clearing blockages in a row of ventilation slots. This eliminates the trouble of climbing to the high installation position of the window frame to drive the vertical slide rod and a row of cleaning levers to clear blockages in the ventilation slots. The operation is simple and efficient, and the safety is good.

[0017] Third, the guide wheels are installed in a sliding manner. By sliding down the two vertical insert shafts and separating them from the two positioning short shafts, the two guide wheels can be slid off the positioning short shafts. After the two guide wheels are removed, they separate from the two arc-shaped baffles, exposing the two annular guide rope grooves. With the two annular guide rope grooves open, the pull ropes that pass through them can be exposed, making it convenient to directly remove and replace the worn pull ropes from the two open annular guide rope grooves. Compared to the design where the two guide wheels are integrated on the two positioning short shafts and cannot be removed, this design avoids the pull ropes being blocked by the two arc-shaped baffles for a long time and confined to the two annular guide rope grooves. The pull ropes cannot be directly removed and replaced from the two annular guide rope grooves and must be removed by pulling the pull ropes through the two annular guide rope grooves. This helps to improve the efficiency of replacing worn or broken pull ropes. Attached Figure Description

[0033] Please refer to Figures 1 to 7 ;

[0034] Example 1:

[0035] This utility model proposes a ventilation window for a shed, including: a window frame 1, inside which a row of horizontal support plates 101 are fixedly arranged at equal intervals, and an arc-shaped windbreak plate 102 is welded to the middle position of the horizontal support plates 101 in the height direction.

[0036] A vertical sliding rod 2 is slidably installed on the bottom horizontal brace 101; a vertical positioning shaft 104 is welded to a narrow side of a vertical side plate of the window frame 1, and a bushing 105 is slidably installed on the vertical positioning shaft 104; a connecting rod 203 is rotatably connected between the bushing 105 and the bottom part of the vertical sliding rod 2; a downward pulling rope 3 and an upward pulling rope 3 are connected to the bushing 105; positioning short shafts 10 are symmetrically welded at the two corners at the top of the window frame 1. 3. Two guide wheels 107 are rotatably installed on the two positioning short shafts 103; the tail end of the upward pulling rope 3 passes through the two guide wheels 107 in sequence and is pulled to the bottom of the window frame 1; cleaning shafts 201 are welded on the vertical slide rod 2 at equal intervals; ventilation grooves are formed between every two horizontal support plates 101 and between the upper and lower horizontal support plates 101 and the upper and lower side plates of the window frame 1; a row of cleaning shafts 201 are arranged in a row of ventilation grooves.

[0037] Preferably, the vertical slide bar 2 is located inside the window frame 1, and two L-shaped limiting plates 202 are symmetrically welded to the bottom side of the vertical slide bar 2. The two L-shaped limiting plates 202 slide in cooperation with the long strips at the upper and lower ends of the bottom horizontal support plate 101.

[0038] Preferably, the outer periphery of the guide wheel 107 is provided with an annular guide rope groove, through which the pull rope 3 is guided.

[0039] Preferably, the ends of both pull ropes 3 are connected to rings 301.

[0040] Based on Example 1, Example 2:

[0041] An arc-shaped baffle 1031 is welded onto the positioning short shaft 103. The arc-shaped baffle 1031 is close to the outer periphery of the guide wheel 107 and covers the annular guide rope groove.

[0042] A U-shaped mounting frame 106 is welded to the window frame 1 below the positioning short axis 103. A vertical insertion shaft 1061, which is positioned by spring push, is slidably mounted through the opening of the U-shaped mounting frame 106. The top protruding part of the vertical insertion shaft 1061 is inserted and engaged with the first protruding part of the positioning short axis 103. A limiting ring 1032 is welded and fitted onto the positioning short axis 103. The guide wheel 107 is limited between the limiting ring 1032 and the top protruding part of the vertical insertion shaft 1061.

[0043] Preferably, the guide wheel 107 is installed with the positioning short shaft 103 by means of a sliding fit.

[0044] The following is a detailed explanation and description of the specific details, implementation steps, functions and interrelationships of the above-mentioned features, and their roles in realizing this utility model:

[0045] When in use, the ventilation windows are installed high on the walls of the livestock shed, and the air inside and outside the livestock shed circulates and exchanges through a row of ventilation slots.

[0046] When the vertical slide bar 2 slides back and forth along the bottom horizontal support plate 101, a row of cleaning pins 201 on it can be used to scrape and remove the spider webs and debris trapped and accumulated by the spider webs in a row of ventilation slots, thus completing the unblocking and clearing of a row of ventilation slots.

[0047] The connecting rod 203, bushing 105, and vertical slide bar 2 are connected to form a crank-slider mechanism. Through this mechanism, the vertically sliding bushing 105 can drive the vertical slide bar 2 to slide back and forth along the bottom horizontal support plate 101. The downward pulling rope 3 can pull the bushing 105 down to slide along the vertical positioning shaft 104. Guided by the two guide wheels 107, the upward pulling rope 3 can drive the bushing 105 up to slide along the vertical positioning shaft 104. Since the tail ends of the two pulling ropes 3 are both suspended by the pull rope, Below the window frame 1, each section has a certain hanging length, allowing workers to stand on the ground at a low position and alternately pull down the pull rope 3 to drive the shaft sleeve 105 to slide up or down, controlling the vertical slide rod 2 and a row of cleaning shafts 201 to slide back and forth, clearing blockages in a row of ventilation slots. This eliminates the need to climb to the high installation position of the window frame 1 to drive the vertical slide rod 2 and the row of cleaning shafts 201 to clear blockages in the ventilation slots. The operation is simple, efficient, and safe.

[0048] Two arc-shaped baffles 1031 can prevent the upward pulling rope 3 from slipping off the two guide wheels 107 during use; the vertical insert shaft 1061 can insert and position the guide wheel 107 on the positioning short shaft 103; the guide wheel 107 is slidably installed, and by sliding the two vertical insert shafts 1061 down and separating them from the two positioning short shafts 103, the two guide wheels 107 can be slid off the positioning short shafts 103. After the two guide wheels 107 are removed, they separate from the two arc-shaped baffles 1031, and the two annular guide rope grooves can be exposed. After the annular guide groove is opened, the pull rope 3 that passes through it can be exposed, which makes it convenient to directly remove and replace the worn pull rope 3 from the two open annular guide grooves. Compared with the design of integrating the two guide wheels 107 on the two positioning short shafts 103 and making them non-removable, this avoids the pull rope 3 being blocked by the two arc-shaped baffles 1031 for a long time and being restricted to the two annular guide grooves. It also avoids the need to remove the pull rope 3 by pulling it through the two annular guide grooves. This helps to improve the efficiency of replacing the worn or broken pull rope 3.
