[0002] Steel structure workshop is a kind of building with steel as the main structural frame, which has many remarkable characteristics. Its main structure is composed of steel structural components such as steel beams and steel columns, which are durable and have strong bearing capacity. The construction period is short and it can be put into use quickly. The space layout is flexible and can be reasonably divided and transformed according to different needs. It has good seismic performance and can also ensure safety in some earthquake-prone areas. Its appearance is simple and modern, and the maintenance cost is relatively low. Steel structure workshops are widely used in industrial production, warehousing and logistics and other fields, providing a stable and reliable space for the production and operation of enterprises, and strongly promoting economic development.

[0003] In order to protect the goods and equipment inside, the vents of steel structure factories usually have special requirements for windproof and waterproof (corresponding ventilation components need to be installed for protection). However, installing ventilation components (such as filters) on the vents will inevitably affect the ventilation effect of the steel structure factory. The traditional ventilation structure cannot adjust the ventilation components installed on the vents according to different weather and usage scenarios, resulting in poor use effect.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a ventilation structure for a steel structure factory building. Utility Model Content

[0028] like Figure 1-4As shown, the utility model provides a ventilation structure of a steel structure factory building, including a ventilation pipe 1 arranged on the wall of the factory building and penetrating the wall, a plurality of ventilation components 3 driven by a rotating assembly 2 are arranged on the surface of the ventilation pipe 1, a dustproof shell 4 located above the ventilation pipe 1 and opening downward is arranged on the outside of the ventilation component 3, and a locking assembly 5 is also installed on the surface of the ventilation component 3. When a suitable ventilation component 3 is rotated to be flush with the ventilation pipe 1, the position of the ventilation component 3 is fixed by the locking assembly 5. The four ventilation components 3 correspond to a glass fiber filter, an expanded polytetrafluoroethylene filter (two filters are fixed in the frame), a closing plate and a fan, respectively. Of course, other ventilation components 3 can also be selected as needed, and there is no restriction on the selection of the ventilation component 3.

[0029] A mounting plate A6 is welded on the outer wall of the ventilation duct 1, and mounting plates B7 are welded on both sides of the dustproof shell 4, and the mounting plates A6 and B7 are located on the same horizontal plane, that is, when installing the ventilation structure, a through groove is reserved on the steel structure factory for the ventilation duct 1 to pass through. After the ventilation duct 1 is embedded in the through groove, the mounting plates A6 and B7 are just in contact with the wall of the steel structure factory, and then fixed to the wall by screws 12 to complete the installation of the ventilation structure.

[0030] The ventilation component 3 is rotated by the rotating component 2, so that different ventilation components 3 are flush with the ventilation pipe 1. After adjusting the appropriate ventilation component 3, the rotating component 2 is locked by the locking component 5 to fix the position of the ventilation component 3. In this way, the ventilation component 3 installed on the vent can be adjusted according to different weather and usage scenarios. The four ventilation components 3 listed above, when the glass fiber filter is flush with the ventilation pipe 1, the glass fiber filter has a certain dust removal performance and can be used in the use scene with more dust around. When the expanded polytetrafluoroethylene filter is flush with the ventilation pipe 1, the filter is effectively isolated from water to cope with ventilation on rainy days. When the closing plate (sealing pad is set on the closing plate) is flush with the ventilation pipe 1, the ventilation pipe 1 can be closed. This is mainly used when placing goods that do not need ventilation in the factory. When the fan and the ventilation pipe 1 are flush, the fan promotes the circulation of air and improves the ventilation effect. At the same time, the unused ventilation components 3 will be temporarily hidden in the dustproof shell 4 with the opening facing downward, which can be well dustproof.

[0031] The rotating assembly 2 includes a bearing A201 embedded and fixed on the surface of the ventilation pipe 1, and a rotating rod 202 is fixedly connected to the inner ring of the bearing A201, and the outer wall of the rotating rod 202 is fixedly connected to the connecting rod 203 (the connecting rods 203 are at right angles to each other) at the surrounding parts of the inner part of the dustproof shell 4, and the heads of the connecting rods 203 are detachably connected to the ventilation component 3. The locking assembly 5 includes a connecting groove seat 501 welded to the outer wall of the rotating rod 202 located at the surrounding parts of the outer side of the dustproof shell 4 (the connecting groove seats 501 are also at right angles to each other), and a bearing seat 502 fixed on both sides of the surface of the dustproof shell 4 above the bearing A201, and the inner installation of the bearing seat 502 There is a bearing B503, and a cylindrical rod 504 is fixedly connected in the inner ring of the bearing B503, a threaded rod 505 is welded between the cylindrical rods 504, and the threads on both sides of the threaded rod 505 are opposite and symmetrical, rod sleeves 506 are threadedly connected on both sides of the outer wall of the threaded rod 505, and the bottom of the rod sleeve 506 is fixedly connected with a fixed block 508 that can be inserted into the connecting groove seat 501 through a vertical plate 507, a guide rail 509 is fixedly connected to the surface of the dustproof shell 4, and the back of the rod sleeve 506 is slidably connected in the guide rail 509 through a slider 510, and a handle 511 is fixedly connected to the opposite end of the cylindrical rod 504 and the threaded rod 505 for facilitating its rotation.

[0032] That is, rotate the rotating rod 202 (the rotating rod 202 can be rotated by connecting the groove seat 501), the rotating rod 202 rotates along the inner ring of the bearing A201, and the inner ring of the bearing A201 rotates along its outer ring to support the rotation of the rotating rod 202. The rotating rod 202 rotates the appropriate ventilation component 3 to a position flush with the ventilation pipe 1 through the connecting rod 203. After adjusting the appropriate ventilation component 3, turn the handle 511 clockwise, the handle 511 drives the rotation of the cylindrical rod 504, and the cylindrical rod 504 drives the threaded rod 505 to rotate clockwise. At this time, the cylindrical rod 504 also drives the rotation of the inner ring of the bearing B503, and the inner ring of the bearing B503 rotates along its outer ring, thereby rotatably supporting the threaded rod 505, and the threaded rod 505 drives the rod sleeves 506 on both sides to rotate clockwise. The middle part (this is because the threads on both sides of the screw are opposite and symmetrical about the middle part) moves, the rod sleeve 506 drives the movement of the slider 510, and the slider 510 slides along the guide rail 509 to maintain the linear movement of the rod sleeve 506. The rod sleeve 506 can drive the two fixed blocks 508 to move toward the middle part in a straight line through the vertical plate 507, so as to be inserted into the connecting groove seat 501 at the corresponding angle of the rotating rod 202 (before the fixed block 508 is inserted, the connecting groove seat 501 needs to be supported), completing the locking of the rotating component 2, thereby achieving the fixation of the ventilation component 3. Similarly, turning the handle 511 counterclockwise will drive the threaded rod 505 to rotate counterclockwise, and finally drive the two fixed blocks 508 to move to both sides, canceling the locking of the rotating component 2, and the ventilation component 3 can be adjusted again.

[0033] Furthermore, a groove seat 8 is welded on the outer wall of the ventilation component 3, and a protrusion 9 that can be inserted into the groove seat 8 is fixedly connected to the head of the rotating rod 202. A screw hole 10 is opened on the surface of the protrusion 9, and a through hole 11 is opened on the surface of the groove seat 8. A screw 12 is installed at the opening of the through hole 11, and the screw 12 is sequentially passed through the through hole 11 downward and then installed into the screw hole 10 by turning the screw 12 clockwise, that is, the groove seat 8 on the ventilation component 3 is inserted into the protrusion 9 of the rotating rod 202 (if the ventilation component Part 3 is a filter screen, then the groove seat 8 is arranged on the frame around it). After the insertion is completed, the through hole 11 and the screw hole 10 are aligned, and the screw 12 can be passed through the through hole 11 and then the screw is turned clockwise to install it into the screw hole 10, thereby achieving the fixation between the ventilation component 3 and the connecting rod 203. Conversely, the screw 12 can be removed, and the groove seat 8 can be pulled off the protrusion 9 to achieve the disassembly of the ventilation component 3. The disassembly and assembly are very convenient, so it is convenient to repair, clean or replace the ventilation component 3.
