[0039] Please refer to Figures 1 to 4The present application proposes a ventilation device for an underground pipe gallery, including a ventilation shaft 200 arranged on the underground pipe gallery 100, the underground pipe gallery 100 is connected to the air outside the ground through the ventilation shaft 200, the ventilation shaft 200 is located on the ground, the ventilation shaft 200 includes a connecting body 210, a cover body 220 and a ventilation device 230, the connecting body 210 is provided with a ventilation hole 211, the ventilation hole 211 is connected to the underground pipe gallery 100; the cover body 220 is provided with a receiving groove 2211, the cover body 220 can be covered on the connecting body 210, and the receiving groove 2211 is connected to the ventilation hole 211; the ventilation device 230 is arranged in the receiving groove 2211, the ventilation device 230 can drive the air in the underground pipe gallery 100 to flow to the outside of the ground or drive the air outside the ground to flow to the underground pipe gallery 100.

[0040] Specifically, the underground pipe gallery 100 is connected to the air outside the ground through the ventilation shaft 200. The ventilation shaft 200 is located on the ground, rather than the part usually located underground in the traditional way. The ventilation shaft 200 does not occupy the space inside the pipe gallery, thereby providing greater flexibility for the layout of other facilities or pipelines. In addition, placing the ventilation shaft 200 on the ground can improve the convenience of maintenance and reduce maintenance costs, because the ventilation equipment is easier to access and repair. The cover body 220 can be covered on the connector 210 to prevent rainwater from falling into the underground pipe gallery 100. The accommodating groove 2211 of the cover body 220 is connected to the ventilation hole 211, and the ventilation hole 211 of the connector 210 is connected to the underground pipe gallery 100. This direct connection design enhances the efficiency of air flow and ensures that the interior of the pipe gallery can continuously obtain a supply of fresh air, thereby improving the internal working environment and ensuring the health and safety of the staff. The ventilation device 230 is arranged in the receiving groove 2211. The ventilation device 230 has a two-way ventilation function, which can push the air in the underground tunnel 100 to flow outward, and can also attract external air to enter, so that the internal environment of the tunnel can be quickly adjusted according to needs, whether it is to eliminate harmful gases or adjust temperature and humidity, it can respond quickly.

[0041] Please refer to Figure 2 and Figure 3 In one embodiment, the cover body 220 is provided with a plurality of first openings 2212 , and the first openings 2212 are communicated with the receiving grooves 2211 .

[0042] Specifically, the first openings 2212 allow more air to enter or leave the receiving groove 2211 through the cover 220, thereby improving ventilation efficiency, allowing air to flow more freely and reducing resistance to air flow. When the ventilation device 230 needs to exhaust the air in the tunnel, the multiple first openings 2212 can effectively disperse the exhausted air and reduce interference with the internal airflow. At the same time, when air is inhaled from the outside, it can also ensure that a sufficient amount of air enters the tunnel, maintaining the freshness of the air in the underground tunnel 100 and the balance of the environment.

[0043] Please refer to Figure 3 In one embodiment, a plurality of fixing posts 2213 are provided on the side of the cover body 220 facing the connecting body 210, and a plurality of fixing holes (not marked in the drawings) are provided on the side of the connecting body 210 facing the cover body 220. The fixing posts 2213 correspond to the fixing holes one by one. When the plurality of fixing posts 2213 are respectively inserted into a fixing hole, the cover body 220 is covered on the connecting body 210.

[0044] Specifically, the connector 210 is provided with a plurality of fixing holes on one side facing the cover 220, and the fixing posts 2213 correspond to the fixing holes one by one. When the plurality of fixing posts 2213 are respectively inserted into a fixing hole, the cover 220 is covered on the connector 210, so that the connection between the cover 220 and the connector 210 is more stable, and the cover 220 is prevented from loosening or falling off due to airflow or external environmental factors (such as strong wind, earthquake, etc.) during ventilation. The technician only needs to lift the cover 220 upward in the vertical direction to separate the cover 220 from the connector 210, and the technician can also enter the underground pipe gallery 100 through the ventilation holes 211 in the connector 210. This quick positioning and locking mechanism not only simplifies the installation process of the device, but also allows the technician to easily enter the underground pipe gallery 100 through the ventilation holes 211 in the connector 210 for inspection or maintenance, which facilitates future maintenance and overhaul work.

[0045] Please refer to Figure 3 In one embodiment, a plurality of second openings 212 are formed on the radial side of the connecting body 210 , and the second openings 212 are connected to the ventilation holes 211 .

[0046] Specifically, the plurality of second openings 212 can effectively disperse the exhausted air and reduce interference with the internal airflow. At the same time, when air is inhaled from the outside, a sufficient amount of air can be ensured to enter the tunnel, thereby maintaining the freshness of the air in the underground tunnel 100 and the balance of the environment.

[0047] Please refer to Figure 1 In one embodiment, the second opening 212 is spaced apart from the ground.

[0048] Specifically, the second opening 212 is spaced apart from the ground, thereby preventing rainwater from directly flowing from the ground into the ventilation hole 211 .

[0049] Please refer to Figure 2 and Figure 3 In one embodiment, the cover body 220 includes an annular body 221 and a conical portion 222. The annular body 221 is detachably connected to the connecting body 210. The annular body 221 is provided with a plurality of first openings 2212 along the radial side. The conical portion 222 is fixedly connected to the annular body 221, and external rainwater can flow to the ground through the surface of the conical portion 222.

[0050] Specifically, the annular body 221 is detachably connected to the connecting body 210 to optimize ventilation effect and provide waterproof protection. The annular body 221 is provided with a plurality of first openings 2212 along the radial side, and the plurality of first openings 2212 provide necessary ventilation channels for the underground pipe gallery 100. At the same time, the design of the conical portion 222 allows rainwater to flow from the surface of the cover body 220 to the ground, preventing water accumulation and infiltration.

[0051] Please refer to Figure 5 In one embodiment, a solar panel (not marked in the drawings) is laid on the side of the conical portion 222 facing away from the annular body 221, and the ventilation device 230 is electrically connected to the solar panel.

[0052] Specifically, the ventilation device 230 is electrically connected to the solar panel, which collects solar energy and converts it into electrical energy for use by the ventilation device 230. In this way, the ventilation system can operate without relying on an external power source, which is particularly suitable for areas far away from the city power grid or areas that want to reduce energy consumption. In addition, arranging the solar panel on the outside of the cone 222 can maximize the efficiency of capturing solar energy while keeping the device neat and beautiful. This design can also be combined with other renewable energy technologies, such as wind energy, or by using a backup power system (such as a battery) to further enhance the energy self-sufficiency and flexibility of the system.

[0053] Please refer to Figure 4 In one embodiment, the maximum diameter of the conical portion 222 is greater than the maximum diameter of the annular body 221 , and the maximum diameter of the annular body 221 is equal to the maximum diameter of the connecting body 210 .

[0054] Specifically, by making the maximum diameter of the cone 222 larger than the maximum diameter of the annular body 221, and the maximum diameter of the annular body 221 being equal to the maximum diameter of the connecting body 210, the cone 222 naturally guides rainwater to flow out smoothly, preventing rainwater from accumulating and seeping into the vent 211. The enlarged diameter of the cone 222 allows rainwater to be directly guided to the periphery of the annular body 221 when it flows down from the cone surface, rather than dripping inside. This design utilizes the principles of gravity and hydrodynamics to ensure that water flows outward and is smoothly discharged to the ground.

[0055] Please refer to Figure 1 In one embodiment, the underground pipe gallery 100 is provided with a rectangular groove 110 , which is connected to the ventilation hole 211 , so that technicians can enter the underground pipe gallery 100 through the rectangular groove 110 .

[0056] Specifically, the rectangular groove 110 is connected to the ventilation hole 211, so that technicians or maintenance personnel can easily enter the underground pipe gallery 100 through the rectangular groove 110. The setting of the rectangular groove 110 ensures that the practicality of the ventilation hole 211 is not limited to ventilation, but also acts as an entry point, thereby simplifying the process of entering the underground space.

[0057] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
