[0017] As an alternative solution for a building ventilation structure and its usage method according to the present invention, the usage steps are as follows:

[0018] Step 1: During use, when the building workshop needs ventilation, the ventilation mechanism is started at this time. The ventilation mechanism drives the guiding mechanism to rotate, and at the same time, the guiding mechanism automatically opens to both sides for subsequent ventilation.

[0019] Step 2: When the ventilation mechanism is started to drive the guiding mechanism to rotate, it simultaneously drives the support mechanism to start. The baffle inside the support mechanism is lifted, and both sides of the ventilation frame open. At this time, air can enter the workshop interior through the guiding mechanism normally, achieving the purpose of ventilation.

[0020] Step 3: When the support mechanism moves, the support mechanism slides normally inside the filtering mechanism for filtering impurities.

[0021] Step 4: During use, to prevent air from one side from being discharged through the other side of the ventilation frame, by adjusting the wind direction adjustment mechanism, it is possible to ensure that air enters the workshop interior, thereby ensuring normal air flow and achieving the purpose of ventilation.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] In the present invention, a ventilation mechanism is provided at the top of the workshop. During ventilation, by starting the ventilation mechanism, the motor drives the threaded rod to rotate, thereby causing the threaded sleeve to move upward and the top plate to move upward. The top plate drives the first hydraulic rods on both sides to move upward. Through the first hydraulic rods, the guiding mechanism can be driven to rotate. At this time, the guiding mechanism opens. According to the actual wind direction, the first hydraulic rods can be started to rotate one side of the guiding mechanism, and air enters the lower side through the guiding mechanism on the other end for ventilation purposes. This setting can direct the air through the guiding mechanism, and the air circulation speed inside the workshop is very fast. In rainy and snowy weather, by starting the ventilation mechanism, the guiding mechanism is contracted, thus preventing rainwater from entering the workshop interior.

[0024] When the ventilation mechanism is started, it can drive the support mechanism to move. While the support mechanism is moving, the baffles on both sides of the ventilation frame open, ensuring that air can enter the workshop interior normally and guaranteeing rapid air circulation.

[0025] During actual use, it is possible for impurities to enter the interior of the factory building. The device is provided with a filtering mechanism on the outside of the supporting mechanism. When the baffle is opened, the folding net inside the filtering mechanism moves upward, and the filtering cover is activated to block impurities. When the baffle is closed, the folding net shrinks to ensure the normal use of the equipment.

[0026] To prevent air from entering through one side of the ventilation frame and discharging from the other side, a wind direction adjustment mechanism is provided inside the ventilation frame. The wind direction adjustment mechanism on the side where air enters moves its wind direction plate upward by activating the second hydraulic rod to ensure the normal entry of air. The wind direction plate on the other side moves downward to block the other side of the ventilation frame and prevent air from directly discharging, ensuring the normal entry of air into the factory building and achieving rapid air ventilation.

[0035] Embodiment 1:

[0036] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution:

[0037] A building ventilation structure and a using method, including a factory building roof 1 and a factory building 5. The factory building roof 1 is installed on the top of the above-mentioned factory building 5. A guiding mechanism 3 for guiding air is rotatably connected to the top of the above-mentioned factory building roof 1 and is symmetrically arranged. A ventilation frame 9 is fixedly connected to the top of the above-mentioned factory building roof 1. A ventilation mechanism 2 for driving the guiding mechanism 3 to move is fixedly connected inside the above-mentioned ventilation frame 9. On both sides of the top of the above-mentioned ventilation mechanism 2, a first hydraulic rod 4 is installed, and the other end of the first hydraulic rod 4 is rotatably connected to the guiding mechanism 3;

[0038] A support mechanism 6 is rotatably connected to the outside of the ventilation mechanism 2 inside the above-mentioned ventilation frame 9, and the other end of the support mechanism 6 is connected to the ventilation frame 9. A filtering mechanism 7 is connected to the outside of the support mechanism 6, and the outside of the filtering mechanism 7 is fixedly connected to the ventilation frame 9;

[0039] Wind direction adjusting mechanisms 8 for adjusting the wind direction are provided on both sides of the above-mentioned ventilation mechanism 2, and the outside of the wind direction adjusting mechanisms 8 is connected to the ventilation frame 9.

[0040] The using steps are as follows:

[0041] Step 1: When in use, ventilation is required for the building factory. At this time, by starting the ventilation mechanism 2, the ventilation mechanism 2 drives the guiding mechanism 3 to rotate, and at the same time, the guiding mechanism 3 automatically opens to both sides for subsequent ventilation;

[0042] Step 2: When the ventilation mechanism 2 starts to drive the guiding mechanism 3 to rotate, it also drives the support mechanism 6 to start. The baffle 606 inside the support mechanism 6 is lifted, and both sides of the ventilation frame 9 are opened. At this time, air can normally enter the interior of the factory building 5 through the guiding mechanism 3 to achieve the purpose of ventilation;

[0043] Step 3: When the support mechanism 6 moves, the support mechanism 6 normally slides inside the filtering mechanism 7 for filtering impurities;

[0044] Step 4: During the use process, to prevent the air on one side from being discharged through the other side of the ventilation frame 9, by adjusting the wind direction adjusting mechanism 8, it can be ensured that the air enters the interior of the factory building 5, thereby ensuring the normal flow of air and achieving the purpose of ventilation.

[0045] During livestock breeding, the air inside the workshop 5 does not circulate, which easily generates odors and breeds bacteria, and can easily cause livestock to get sick. To ensure the air quality inside the workshop 5, ventilation is required. In general livestock breeding, a wind cap is usually installed at the top for ventilation, but this ventilation effect is very limited and the efficiency is poor. When this device ventilates the inside of the workshop 5, it starts the ventilation mechanism 2 and drives the guiding mechanism 3 to open. When the ventilation mechanism 2 starts, it drives the internal support mechanism 6 to move and opens both sides of the ventilation frame 9. At this time, it is ensured that air can directly enter the inside of the workshop 5. Because the guiding mechanism 3 is longitudinally arranged and has a large volume, this ventilation effect is fast. And according to the actual wind direction, by starting the first hydraulic rod 4 to change the height of the guiding mechanism 3, it can ensure that the wind normally enters the inside of the workshop 5. At the same time, to prevent impurities in the air from entering the inside of the workshop 5, the filtering mechanism 7 can block the impurities outside. At the same time, to prevent air from entering through one side of the ventilation frame 9 and discharging through the other side of the ventilation frame 9, a wind direction adjusting mechanism 8 is provided to ensure normal ventilation of the equipment. When not in use or in rainy and snowy weather, it can avoid rain and snow from entering the inside of the workshop 5 by starting the ventilation mechanism 2 and driving the guiding mechanism 3 to close.

[0046] Embodiment 2

[0047] This embodiment is an improvement made to Embodiment 1. Please refer to Figure 1 and Figure 2 Specifically, the above-mentioned ventilation mechanism 2 includes a motor 201, a threaded rod 202, and a threaded sleeve 203. The outside of the above-mentioned motor 201 is fixedly connected to the ventilation frame 9. The end of the main shaft of the above-mentioned motor 201 is fixedly connected to a threaded rod 202. The outside of the above-mentioned threaded rod 202 is spirally connected to a threaded sleeve 203. The top of the above-mentioned threaded sleeve 203 is fixedly connected to a top plate 205. Both sides of the above-mentioned top plate 205 are rotatably connected to a first hydraulic rod 4. Both sides of the above-mentioned top plate 205 are slidably connected to a guide post 206. The bottom of the above-mentioned guide post 206 is fixedly connected to the ventilation frame 9. The outside of the above-mentioned guide post 206 is slidably connected to a sliding table 207. The top of the above-mentioned sliding table 207 is fixedly connected to the top plate 205;

[0048] The outside of the bottom of the above-mentioned threaded sleeve 203 is rotatably connected to a support mechanism 6.

[0049] The outside of the above-mentioned threaded sleeve 203 is slidably connected to a sealing sleeve 204. The bottom of the sealing sleeve 204 is fixedly connected to the ventilation frame 9. The setting of the sealing sleeve 204 is used to prevent rain and snow from penetrating into the inside of the workshop 5 through the connection between the ventilation frame 9 and the threaded sleeve 303, playing a certain sealing role.

[0050] During use, by starting the motor 201, the motor 201 drives the threaded rod 202 to rotate, and the threaded rod 202 drives the threaded sleeve 203 to move. The threaded sleeve 203 drives the top plate 205 above to move, thereby causing the first hydraulic rods 4 on both sides to move. At this time, under the action of the first hydraulic rods 4, the guiding mechanism 3 can be driven to rotate. At this time, the guiding mechanism 3 is opened to achieve the subsequent ventilation function. And guiding columns 206 and sliding platforms 207 are arranged on both sides of the top plate 205 to ensure the stable sliding of the top plate 205 at this time.

[0051] Embodiment 3

[0052] This embodiment is an improvement on Embodiment 2. Please refer to Figure 1 、 Figure 2 and Figure 3 Specifically, the above guiding mechanism 3 includes a wind guiding plate 301, a diversion rod 302 and a connecting column 303. The bottom of the above wind guiding plate 301 is rotatably connected to the factory building roof 1. A uniformly distributed diversion rod 302 is fixedly connected inside the above wind guiding plate 301, and connecting columns 303 are installed on both sides of the wind guiding plate 301.

[0053] The above wind guiding plate 301 is arranged in an arc shape, the above diversion rod 302 is arranged in an arc shape, and the diversion rods 302 are arranged side by side vertically. This arrangement is used to ensure that air is blown downward under the action of the diversion rods 302.

[0054] During use, the wind guiding plate 301 is arranged in an arc shape. When air flows, the air enters the lower part under the guidance of the wind guiding plate 301 and enters the interior of the factory building 5 through both sides of the ventilation frame 9. The arranged diversion rods 302 also serve the purpose of guiding, and the arranged connecting columns 303 serve the purpose of strengthening the wind guiding plate 301 to ensure that the wind guiding plate 301 is not easily deformed or damaged.

[0055] Embodiment 4

[0056] This embodiment is an improvement on Embodiment 3. Please refer to Figure 1 、 Figure 2 and Figure 4 Specifically, the above support mechanism 6 includes a sliding frame 601, a sliding block 602 and a limiting plate 603. The top of the above sliding frame 601 is fixedly connected to the ventilation frame 9. A sliding block 602 is slidably connected inside the above sliding frame 601. One side of the bottom of the sliding block 602 is rotatably connected to a rotating plate 604, and the other end of the rotating plate 604 is rotatably connected to the ventilation mechanism 2. The other side of the bottom of the sliding block 602 is fixedly connected to a support plate 605. The other end of the support plate 605 is slidably connected to a shielding plate 606. The top of the support mechanism 6 is rotatably connected to the ventilation frame 9. A filtering mechanism 7 is slidably connected to the outside of the support plate 605.

[0057] Both sides of the above-mentioned sliding block 602 are fixedly connected with limiting plates 603, and the outer sides of the limiting plates 603 are slidably connected with the sliding frame 601.

[0058] When the motor 201 rotates, its threaded sleeve 203 drives the rotating plate 604 on the outside to move upward, and the rotating plate 604 drives the sliding block 602 to slide inside the sliding frame 601, and the sliding frame 601 drives the support plate 605 to move. When the support plate 605 moves, it can make the baffle plate 606 rotate outward. At this time, the baffle plate 606 opens to ensure that air can enter the workshop 5. The provided limiting plates 603 ensure that the sliding block 602 slides stably inside the sliding frame 601. When not in use, the baffle plate 606 is in a vertical state, which is used to seal the ventilation frame 9 at this time to prevent external rainwater from entering the workshop 5.

[0059] Embodiment 5

[0060] This embodiment is an improvement on Embodiment 4. Please refer to Figure 1 、 Figure 2 and Figure 5 Specifically, the above-mentioned filtering mechanism 7 includes a filter cover 701, a folding net 702 and a sliding sleeve 703. The outside of the filter cover 701 is fixedly connected with the ventilation frame 9. A groove is provided inside the filter cover 701, and a sliding sleeve 703 is provided inside the groove. The outside of the sliding sleeve 703 is rotatably connected with a sliding column 704, and the other end of the sliding column 704 is slidably connected with the filter cover 701. The inside of the sliding sleeve 703 is slidably connected with the support mechanism 6. The outside of the sliding sleeve 703 is fixedly connected with a folding net 702, and the bottom of the folding net 702 is fixedly connected with the filter cover 701.

[0061] When the workshop 5 is ventilated, when the external air passes through the filter cover 701, the impurities in the air are filtered under the action of the filter cover 701. At the same time, with this setting, the support plate 605 can drive the sliding sleeve 703 to move inside the groove, and the sliding sleeve 703 can move up and down under the action of the sliding column 704 on the outside. The folding net 702 at the bottom of the sliding sleeve 703 can be used for blocking to prevent impurities from entering the workshop 5 through the groove. With this setting, when the support plate 605 moves, it drives the sliding sleeve 703 and the folding net 702 to move upward. When the support plate 605 resets, the sliding sleeve 703 and the folding net 702 move downward. At this time, the provided baffle plate 606 is used to block external dust and impurities.

[0062] Embodiment 6

[0063] This embodiment is an improvement on Embodiment 4. Please refer to Figure 1 、 Figure 2 and Figure 6, Specifically, the above-mentioned wind direction adjustment mechanism 8 includes a fixed plate 801, a second hydraulic rod 802 and a wind direction plate 803.

The other end of the second hydraulic rod 802 is rotatably connected to the wind direction plate 803. One end of the wind direction plate 803 is rotatably connected to a rotating shaft 804, and both ends of the rotating shaft 804 are fixedly connected to the ventilation frame 9.

[0064] When air enters the interior of the factory building 5 through the ventilation frame 9, to prevent air from entering through one side of the ventilation frame 9 and discharging through the other side, starting the second hydraulic rod 802 can drive the wind direction plate 803 to rotate under the action of the rotating shaft 804. The wind direction adjustment mechanism 8 at the air inlet of the ventilation frame 9 moves upward to prevent it from blocking the air flow, while the wind direction plate 803 of the wind direction adjustment mechanism 8 on the other side blocks the exhaust part of the ventilation frame 9 to prevent air from directly convecting and discharging, ensuring that air normally enters the interior of the factory building 5. When air enters through the other side of the ventilation frame 9, starting the wind direction adjustment mechanism 8 on the opposite side at this time can achieve the purpose of guiding the wind direction.

The outer side of the fixing plate (801) is fixedly connected to the ventilation frame (9). The second hydraulic rod (802) is rotatably connected to the outer side of the fixing plate (801). The other end of the second hydraulic rod (802) is rotatably connected to the wind direction plate (803). One end of the wind direction plate (803) is rotatably connected to a rotating shaft (804), and both ends of the rotating shaft (804) are fixedly connected to the ventilation frame (9).

9. A method for using a building ventilation structure according to any one of claims 1-8, characterized in that: The usage steps are as follows: Step 1: When in use, ventilation is required for the building factory building. At this time, by starting the ventilation mechanism (2), the ventilation mechanism (2) drives the guiding mechanism (3) to rotate, and at the same time, the guiding mechanism (3) automatically opens to both sides for subsequent ventilation; Step 2: When the ventilation mechanism (2) starts to drive the guiding mechanism (3) to rotate, it simultaneously drives the support mechanism (6) to start, and the baffle (606) inside the support mechanism (6) is lifted, and both sides of the ventilation frame (9) are opened. At this time, air can normally enter the interior of the factory building (5) through the guiding mechanism (3) to achieve the purpose of ventilation; Step 3: When the support mechanism (6) moves, the support mechanism (6) normally slides inside the filtering mechanism (7) for filtering impurities; Step 4: During the use process, to prevent air on one side from being discharged through the other side of the ventilation frame (9), by adjusting the wind direction adjusting mechanism (8), it is possible to ensure that air enters the interior of the factory building (5), thereby ensuring the normal flow of air and achieving the purpose of ventilation.
