Description

Technical Field

[0001] This utility model belongs to the field of building ventilation technology, and in particular relates to a ventilation system based on the top of a building structure. Background Technology

[0002] To facilitate ventilation inside buildings such as factories and stadiums, ventilation windows are usually installed at the top of the building to allow for the exchange of air between the inside and outside.

[0003] Since the sides of existing ventilation windows are generally in the form of grates, the ventilation flow of grates is relatively limited, and the installation angle of their fan blades is relatively fixed, making it impossible to adjust the ventilation flow according to needs. At the same time, they cannot filter external ash and slag. Therefore, we propose a building structure roof ventilation system to solve the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a roof ventilation system based on a building structure, which has adjustable blade angles to regulate the ventilation flow and also filters external ash and slag, in order to solve the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: Based on a building structure top ventilation system, the ventilation system is installed on the top of the building. The ventilation system includes a ventilation window connected to the top of the building. A filter cover is detachably connected inside the ventilation window. A rotating rod is rotatably connected to the front and rear positions of the inner cavity of the ventilation window through a bearing. A fan blade is fixedly sleeved on the surface of the rotating rod. A gear is fixedly connected to one side of the rotating rod, which passes through the ventilation window and extends to the outside of the ventilation window. A slide is fixedly connected to the front and rear positions of one side of the ventilation window. A toothed seat is slidably connected to the outer surface of the slide. One side of the toothed seat meshes with the surface of the gear. A limiting bolt is fixedly connected to the top of the toothed seat. A horizontal plate is fixedly connected to the top of the slide. The limiting bolt passes through the horizontal plate and extends to the top of the horizontal plate. A limiting nut one and a limiting nut two are threadedly connected to the surface of the limiting bolt.

[0006] Preferably, the first limiting nut is located at the bottom of the horizontal plate, and the second limiting nut is located at the top of the horizontal plate. Both the first limiting nut and the second limiting nut are tightly fitted to the horizontal plate.

[0007] Preferably, the length of the slide rail of the slide block is greater than the sliding distance of the toothed seat on the surface of the slide block.

[0008] Preferably, the tooth holder slides on the outer surface of the slide block, driving the gear to rotate, thereby driving the rotating rod to rotate.

[0009] Preferably, a placement plate is fixedly connected to the bottom of the ventilation window's inner cavity, and the top of the placement plate can contact the bottom of the filter cover.

[0010] Preferably, the bottom of the filter cover is threaded with bolts, and the top of the ventilation window is provided with a threaded hole that mates with the bolt threads.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model allows the toothed seat to slide on the outer surface of the slide by pulling or pushing the limiting bolt, thereby meshing the surface of the toothed seat with the gear, which in turn drives the gear to rotate. The rotation of the gear drives the rotating rod to rotate, which in turn drives the fan blade to rotate at an angle. When the rotation reaches an appropriate angle, the limiting nut two and the limiting nut one are threaded and rotated on the outer surface of the limiting bolt, and are tightly fitted with the horizontal plate, thereby achieving the purpose of regulating the ventilation flow. At the same time, the external ash and slag are filtered through the filter cover.

[0013] 2. This utility model avoids the situation where the tooth holder derails due to insufficient sliding distance by making the slide rail length of the slide block greater than the sliding distance of the tooth holder on the slide block surface;

[0014] 3. By setting a placement plate, this utility model can limit the bottom position of the filter cover, thereby supporting the filter cover.

[0015] 4. This utility model features bolts connected to the periphery of the bottom of the filter cover, and threaded holes that mate with the bolts are provided at the top of the ventilation window, which facilitates the disassembly and assembly of the filter cover and improves the ease of replacement.

[0023] In the following description, embodiments of the present invention’s roof ventilation system based on building structure will be described with reference to the accompanying drawings. Example 1

[0024] Figure 1-4 This invention illustrates a rooftop ventilation system based on a building structure, according to an embodiment of the present invention. The ventilation system is installed on the roof of a building 1 and includes a ventilation window 2 connected to the roof of the building 1. A filter cover 3 is detachably connected inside the ventilation window 2. A rotating rod 4 is rotatably connected to the front and rear positions of the inner cavity of the ventilation window 2 via bearings. A fan blade 5 is fixedly sleeved on the surface of the rotating rod 4. A gear 6 is fixedly connected to one side of the rotating rod 4, penetrating the ventilation window 2 and extending to the outside of the ventilation window 2. A sliding seat 7 is fixedly connected to the front and rear positions of one side of the ventilation window 2. A toothed seat 8 is slidably connected to the outer surface of the slide 7. The length of the slide rail of the slide 7 is greater than the sliding distance of the toothed seat 8 on the surface of the slide 7. As the toothed seat 8 slides on the outer surface of the slide 7, it drives the gear 6 to rotate, thereby driving the rotating rod 4 to rotate. Because the length of the slide rail of the slide 7 is greater than the sliding distance of the toothed seat 8 on the surface of the slide 7, it prevents the toothed seat 8 from derailing due to insufficient sliding distance. In the current derailment situation, one side of the gear seat 8 meshes with the surface of the gear 6. A limit bolt 9 is fixedly connected to the top of the gear seat 8. A horizontal plate 10 is fixedly connected to the top of the slide 7. The limit bolt 9 passes through the horizontal plate 10 and extends to the top of the horizontal plate 10. Limit nuts 11 and 22 are threadedly connected to the surface of the limit bolt 9. Limit nut 11 is located at the bottom of the horizontal plate 10, and limit nut 22 is located at the top of the horizontal plate 10. Both limit nuts 11 and 22 are tightly fitted to the horizontal plate 10. By pulling or pushing... The movable limit bolt 9 causes the toothed seat 8 to slide on the outer surface of the slide block 7, thereby causing the surface of the toothed seat 8 to mesh with the gear 6, which in turn drives the gear 6 to rotate. The rotation of the gear 6 drives the rotating rod 4 to rotate, thereby driving the fan blade 5 to rotate at an angle. When it rotates to an appropriate angle, the limit nuts 12 and 11 rotate on the outer surface of the limit bolt 9 through the threads and are tightly fitted with the horizontal plate 10, thereby achieving the purpose of regulating the ventilation flow. At the same time, the filter cover 3 filters the external ash and slag. Example 2

[0025] Figure 1-4This invention illustrates a rooftop ventilation system based on a building structure, according to an embodiment of the present invention. The ventilation system is installed on the roof of a building 1 and includes a ventilation window 2 connected to the roof of the building 1. A filter cover 3 is detachably connected inside the ventilation window 2. A placement plate 13 is fixedly connected to the bottom of the inner cavity of the ventilation window 2, and the top of the placement plate 13 can contact the bottom of the filter cover 3. By setting the placement plate 13, the bottom position of the filter cover 3 can be limited, thus supporting the filter cover 3. Bolts are threadedly connected to the periphery of the bottom of the filter cover 3, and a threaded hole for threaded engagement with the bolts is opened at the top of the ventilation window 2. The threaded hole facilitates the disassembly and assembly of the filter cover 3, thereby improving the ease of replacement. The front and rear positions of the ventilation window 2 are rotatably connected by a bearing. The surface of the rotating rod 4 is fixedly sleeved with a fan blade 5. One side of the rotating rod 4 passes through the ventilation window 2 and extends to the outside of the ventilation window 2, where a gear 6 is fixedly connected. The front and rear positions of one side of the ventilation window 2 are fixedly connected with a slide block 7. The outer surface of the slide block 7 is slidably connected with a toothed seat 8. One side of the toothed seat 8 meshes with the surface of the gear 6. The top of the toothed seat 8 is fixedly connected with a limit bolt 9. The top of the slide block 7 is fixedly connected with a horizontal plate 10. The limit bolt 9 passes through the horizontal plate 10 and extends to the top of the horizontal plate 10. The surface of the limit bolt 9 is threadedly connected with a limit nut 11 and a limit nut 2 12.

[0026] Working principle: When this utility model is in use, by pulling or pushing the limiting bolt 9, the tooth seat 8 slides on the outer surface of the slide block 7, thereby making the surface of the tooth seat 8 mesh with the gear 6, which in turn drives the gear 6 to rotate. The rotation of the gear 6 drives the rotating rod 4 to rotate, thereby driving the fan blade 5 to rotate at an angle. When it rotates to an appropriate angle, the limiting nut 12 and the limiting nut 11 are threaded and rotated on the outer surface of the limiting bolt 9 and are tightly fitted to the horizontal plate 10, thereby achieving the purpose of regulating the ventilation flow. At the same time, the filter cover 3 filters the external ash and slag. The bottom of the filter cover 3 is connected to the bolts by threads, and the top of the ventilation window 2 has a threaded hole that matches the bolt threads, which facilitates the disassembly and assembly of the filter cover 3 and improves the convenience of replacement.
