These air shafts are usually vertical upward channel structures, similar to the shape of a "well", so they are called ventilation shafts;

[0003] For example, the Chinese authorized patent (an air shaft) with the publication number of CN207597818U: includes an air shaft body, an air shaft opening is arranged on the air shaft body, a rain-proof louver is arranged on the air shaft opening, mounting grooves are arranged at both the upper end and the lower end of the air shaft opening, a first pressing plate in contact with the outer side of the rain-proof louver is slidably arranged in the mounting groove, a second pressing plate in contact with the inner side of the rain-proof louver is slidably arranged in the mounting groove, and a driving component for driving the first pressing plate and the second pressing plate to slide in the same direction to clamp the rain-proof louver successively is arranged in the mounting groove; when the rain-proof louver needs to be cleaned, the first pressing plate and the second pressing plate are driven by the driving component to slide in the same direction to disengage from the rain-proof louver successively, and then the rain-proof louver is taken out from the first pressing plate; bolts are not required during installation or disassembly, avoiding the problem of inconvenient disassembly and assembly caused by the cross damage of the bolts, and saving people's time to a certain extent.

[0004] However, the existing air shafts usually use louvers for protection, with a complex fixing structure, inconvenient disassembly and replacement after damage, and a large number are required, making installation and disassembly inconvenient, costly, and due to the large number, the gaps between them are small, resulting in poor ventilation effect; therefore, it does not meet the existing requirements, and for this reason, we propose an air shaft structure for an underground pipe gallery. Content of the Utility Model

[0008] Preferably, an embedded groove is arranged on the inner wall of the connecting groove, and the reinforcing seat is inserted into the embedded groove. Connecting card slots penetrating up and down are arranged on the surface of the reinforcing seat, and the limit connection area of the connecting column is inserted into the connecting card slots.

[0009] Preferably, connecting slots are arranged inside both ends of the reinforcing seat, and resilient metal sheets are inserted into the connecting slots.

[0010] Preferably, the upper surface of the rain shield is composed of an inclined surface and a flat surface, the upper surface of the rain-proof top cover is a sharp conical inclined surface, and both ends of the rain shield are in the form of bevel angles.

[0011] Preferably, four rain shields are arranged on the same horizontal plane, and one rain shield corresponds to two connecting columns. The four rain shields form a group, there are three groups in total, and they are installed at equal distances up and down. And a group of rain shields respectively correspond to a group of upper limit ring seats and lower limit ring seats, and ventilation openings are formed between the upper and lower two groups of rain shields.

The rain shield 3 is fixedly sleeved with the connecting column 4 through the connecting groove 9. An upper limit ring seat 6 is arranged on the outer surface of the connecting column 4. A lower limit ring seat 7 is arranged below the upper limit ring seat 6. A limit connection area 8 is formed between the upper limit ring seat 6 and the lower limit ring seat 7. One upper limit ring seat 6 and one lower limit ring seat 7 form a group, and there are three groups in total, and they are fixed at equal distances up and down. An embedded groove 10 is arranged on the inner wall of the connecting groove 9, and the reinforcing seat 5 is inserted into the embedded groove 10. A connecting card slot 11 penetrating up and down is arranged on the surface of the reinforcing seat 5, and the limit connection area 8 of the connecting column 4 is inserted into the connecting card slot 11.

[0023] The reinforcing seat 5 is inserted into the embedded groove 10. The rain shield 3 installed with the reinforcing seat 5 is aligned with the limit connection area 8 formed between the upper limit ring seat 6 and the lower limit ring seat 7 and squeezed. The limit connection area 8 of the connecting column 4 is inserted into the connecting card slot 11 of the reinforcing seat 5, that is, inserted into the connecting groove 9 of the rain shield 3. The reinforcing seat 5 made of rubber material contacts the outer wall of the connecting column 4 to increase the friction force. The upper limit ring seat 6 and the lower limit ring seat 7 are used to limit the rain shield 3 to prevent warping and falling. In this way, the installation of one rain shield 3 is realized, and the other three rain shields 3 are installed in the other three directions in the same way. When disassembling and replacing the rain shield 3, only need to pull the rain shield 3 forcefully. When installing, squeeze it forcefully, which is simple and convenient.

[0024] Please refer to Figure 2 , 4 , connecting slots 12 are arranged inside both ends of the reinforcing seat 5. A ductile metal sheet 13 is inserted into the connecting slots 12. The reinforcing seat 5 is inserted into the embedded groove 10, and then the ductile metal sheet 13 is inserted into the connecting slots 12 to improve the firmness and solidity of both ends of the reinforcing seat 5.

Four rain shields 3 form a group, and a total of three groups are arranged, and they are installed at equal distances up and down. And a group of rain shields 3 respectively correspond to a group of upper limit ring seats 6 and lower limit ring seats 7. A ventilation opening 16 is formed between the upper and lower groups of rain shields 3. Four rain shields 3 also form a group, and a total of three groups, which are respectively connected to three groups of limit connection areas 8. A ventilation opening 16 is formed between the upper and lower groups of rain shields 3 for ventilation. There are ventilation openings 16 all around, which improves the ventilation effect.

[0027] Working principle: When in use, the strengthening seat 5 is inserted into the inner embedding groove 10, and then the resilient metal sheet 13 is inserted into the connection slot 12 to improve the firmness and strength at both ends of the strengthening seat 5 and enhance the firmness and stability of the connection with the connecting column 4. Then, the rain shield 3 installed with the strengthening seat 5 is aligned with the limit connection area 8 formed between the upper limit ring seat 6 and the lower limit ring seat 7 and squeezed. The limit connection area 8 of the connecting column 4 is inserted into the connection card slot 11 of the strengthening seat 5, that is, into the connection groove 9 of the rain shield 3. The strengthening seat 5 made of rubber material contacts the outer wall of the connecting column 4 to increase the friction force, and the connecting column 4 is squeezed on both sides by the resilient metal sheet 13 to further improve the connection stability. At the same time, the rain shield 3 is limited by the upper limit ring seat 6 and the lower limit ring seat 7 to prevent warping and falling. In this way, the installation of one rain shield 3 is realized, and the other three rain shields 3 are installed in the other three directions in the same way. After installation, the edges of each rain shield 3 are connected by bevel angles 18 to form a square. Four rain shields 3 form a group, and a total of three groups, which are respectively connected to three groups of limit connection areas 8. A ventilation opening 16 is formed between the upper and lower groups of rain shields 3 for ventilation. There are ventilation openings 16 all around, which improves the ventilation effect. And the upper surface of the rain shield 3 is composed of an inclined surface 14 and a flat surface 15. The flat surface 15 is used for connection, and the inclined surface 14 is used for rain shielding. Coupled with the rain-proof top cover 2 with a pointed conical inclined surface 17, rainwater accumulation is avoided, which has a water diversion effect and improves the rain-proof effect. When disassembling and replacing the rain shield 3, only need to pull the rain shield 3 forcefully. When installing, squeeze it forcefully, which is simple and convenient.
