They are shallowly buried, highly intensive, and lightweight, and can accommodate power pipelines, communication pipelines, water supply pipelines, recycled water pipelines, and thermal pipelines. Due to their good effectiveness and feasibility in solving the last mile pipeline problem for users, small integrated pipe corridors have a huge market potential. However, the ventilation equipment of small integrated pipe corridors has the following disadvantages:
[0003] First, it is necessary to set up a mezzanine between the underground corridor and the ground, and to install the fans used for ventilation in the mezzanine, which results in the ventilation node area, height and burial depth being too large, the construction cost of the underground corridor increasing, and the utilization rate of the underground space being low, which is not conducive to the intensive and sustainable development of urban underground space.

[0051] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.
[0052] like Figure 1 As shown, the present invention provides a ventilation device, which includes a ventilation box 1, a fan 2 and an air duct 3. A ventilation chamber 101 is formed inside the ventilation box 1, and an air port 102 connected to the ventilation chamber 101 is provided on the ventilation box 1. The fan 2 is located in the ventilation chamber 101, and the air duct 3 has at least a first port 301 and a second port 302. The first port 301 is located outside the ventilation chamber 101, and the second port 302 is connected to the fan 2.
[0053] The present invention forms a ventilation chamber 101 inside the ventilation box 1, and is provided with an air outlet 102 connected to the ventilation chamber 101 on the ventilation box 1, and is provided with a fan 2 in the ventilation chamber 101, and the first port 301 of the air duct 3 is located outside the ventilation chamber 101, and the second port 302 of the air duct 3 is connected to the fan 2. The fan 2 is turned on regularly according to the actual ventilation requirements to perform mechanical ventilation, and the air is driven by the fan 2 to flow between the air duct 3, the ventilation chamber 101 and the air outlet 102, so as to ventilate the underground corridor and achieve the purpose of controlling the temperature and air quality in the underground corridor. The ventilation device of the present invention realizes the function of a ventilation node, and can be set at any position on the underground corridor according to the actual needs and ventilation effect requirements. Under the premise that the ventilation effect meets the ventilation and heat dissipation requirements of the underground corridor, the number of fans 2 used is reduced and the setting method of the fans 2 is changed, so that the integration is higher, the ventilation system is made lighter, the construction cost of the underground corridor is effectively reduced, and the utilization rate of urban underground space is improved.
[0054] In an optional embodiment of the present invention, Figure 1 As shown, the ventilation box 1 is a horizontally arranged rectangular parallelepiped, with air vents 102 located at the top of the ventilation box 1. The ventilation box 1 is located below the ground, and the air vents 102 are flush with the ground. The ventilation chamber 101 is connected to the outside world through the air vents 102. By setting the air vents 102 flush with the ground, the area of the ventilation nodes is effectively reduced while achieving the desired ventilation effect. Moreover, the ventilation nodes do not need to be exposed above the ground, which does not damage the aesthetics of the environment and has a wider range of applications. Of course, the ventilation box 1 can also have other shapes to adapt to the ground surface of different environments, as long as the air vents 102 are flush with the ground.
[0055] Further, such as Figure 1As shown, a ventilation cover 8 having multiple ventilation holes is provided at the air vent 102. The ventilation cover 8 is made of metal and serves to intercept foreign matter, preventing it from entering the ventilation box 1 through the air vent 102. Furthermore, the provision of the ventilation cover 8 facilitates maintenance and repair of equipment such as the fan 2 within the ventilation box 1, while preventing non-staff members from entering the ventilation box 1 and the underground tunnel through the air vent 102.
[0056] Further, such as Figure 1 As shown, a connection structure 7 is provided on the air duct 3, and the air duct 3 is connected to the ventilation box 1 through the connection structure 7. The connection structure 7 may adopt, but is not limited to, a water-stop flange, thereby playing a waterproof role, preventing water from entering the interior of the ventilation box 1 through the second opening 302, and avoiding damage to the fan 2. Of course, the connection structure 7 may also adopt a flexible waterproof casing or a prefabricated waterproof wall-penetrating module made of EPDM. During the actual assembly process, the water-stop flange, flexible waterproof casing or prefabricated waterproof wall-penetrating module made of EPDM can be selected and installed according to the groundwater conditions and actual needs. While ensuring waterproof and sealing effects, it is suitable for the connection and assembly needs of various types and diameters of air ducts, and can achieve the effects of convenient installation and strong applicability.
[0057] In an optional embodiment of the present invention, Figure 1 As shown, the ventilation device further includes a guide pipe 5. A floor drain 6 is provided at the bottom of the ventilation box 1. The inlet of the floor drain 6 is connected to the ventilation chamber 101, and the outlet of the floor drain 6 is connected to the guide pipe 5. The accumulated water flowing into the ventilation chamber 101 through the air outlet 102 is discharged through the guide pipe 5, thereby achieving the purpose of draining the accumulated water and ensuring the safe operation of the fan 2.
[0058] Further, such as Figure 1 As shown, the bottom surface of the ventilation chamber 101 is a diversion slope 4 that is inclined from away from the diversion pipe 5 to close to the diversion pipe 5. The diversion slope 4 plays a diversion role for the accumulated water flowing into the ventilation chamber 101, so that the accumulated water in the ventilation chamber 101 is fully discharged.
[0059] The characteristics and advantages of the ventilation device of the present invention are:
[0060] 1. The ventilation device can realize the function of a ventilation node and can be set at any position on the underground pipe gallery according to actual needs and ventilation effect requirements. On the premise that the ventilation effect meets the ventilation and heat dissipation requirements of the underground pipe gallery, the number of fans 2 used is reduced and the setting method of the fans 2 is changed, the integration is higher, the ventilation system is made lighter, the construction cost of the underground pipe gallery is effectively reduced, and the utilization rate of urban underground space is improved.
[0061] Second, in the ventilation device, the air outlet 102 is set flush with the ground, which effectively reduces the area of the ventilation node while achieving the ventilation effect. Moreover, the ventilation node does not need to be exposed above the ground, which will not damage the beauty of the environment, nor will it limit the location of the ventilation device due to the ground environment, and has a wider range of applications.
[0062] 3. In this ventilation device, by setting a ventilation cover 8 at the air outlet 102, it can not only intercept foreign matter and prevent external foreign matter from entering the ventilation box 1 through the air outlet 102, but also make it convenient for staff to directly enter the ventilation box 1 through the air outlet 102 to maintain and repair equipment such as the fan 2, while other non-staff cannot enter the ventilation box 1 and the underground corridor through the air outlet 102.
[0063] Implementation Method 2
[0064] like Figures 1 to 8 As shown, the present invention provides an underground tunnel, which includes a tunnel main body 2001 and at least two of the above-mentioned ventilation devices 1000. A accommodating chamber 2002 is formed inside the tunnel main body 2001. The tunnel main body 2001 is provided with at least a first ventilation port 2008 and a second ventilation port 2009 that are connected to the accommodating chamber 2002. Among the two ventilation devices 1000, the first port 301 of the air duct 3 in one of the ventilation devices 1000 is connected to the first ventilation port 2008, and the first port 301 of the air duct 3 in the other ventilation device 1000 is connected to the second ventilation port 2009. During operation, the fans 2 in the two ventilation devices 1000 are started at the same time, the air outlet 102 in one ventilation device 1000 serves as an air inlet, and the air outlet 102 in the other ventilation device 1000 serves as an air outlet. The air in the external environment enters the containing chamber 2002 of the tunnel main body 2001 through the air outlet 102 in one ventilation device 1000, and then the original air in the containing chamber 2002 is discharged to the outside through the air outlet 102 in the other ventilation device 1000, thereby realizing ventilation of the containing chamber 2002 of the tunnel main body 2001.
[0065] Furthermore, the air ducts 3 in the two ventilation devices 1000 are respectively connected to the first ventilation port 2008 and the second ventilation port 2009 through flange structures, which facilitates the assembly and disassembly of the ventilation devices 1000, so that when the ventilation devices 1000 are set on the pipe gallery main body 2001, the position, direction and spacing between the two ventilation devices 1000 can be flexibly arranged.
[0066] In an optional embodiment of the present invention, Figures 3 to 8As shown, there is a vertical height difference between the first vent 2008 and the second vent 2009, which increases the fluidity of air in the accommodating chamber 2002, improves the ventilation effect, and meets the ventilation requirements. Among them, it is preferred to set the first vent 2008 near the top of the accommodating chamber 2002 and the second vent 2009 near the bottom of the accommodating chamber 2002, or to set the second vent 2009 near the top of the accommodating chamber 2002 and the first vent 2008 near the bottom of the accommodating chamber 2002, so that there is as large a height difference as possible between the first vent 2008 and the second vent 2009.
[0067] Furthermore, in the first ventilation port 2008 and the second ventilation port 2009, the air vent with a smaller height is used to input fresh air from the outside into the accommodating chamber 2002, and the original air in the accommodating chamber 2002 is discharged through the air vent with a larger height, thereby utilizing the principle of rising air flow to play an auxiliary ventilation role, improve ventilation efficiency, and reduce the energy consumption of the fan 2.
[0068] Further, such as Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 As shown, grille plates 9 are provided at the first ventilation opening 2008 and the second ventilation opening 2009, and the grille plates 9 can block foreign matter.
[0069] Further, such as Figure 3 、 Figure 6 As shown, the first vent 2008 and the second vent 2009 are respectively located on the two opposite side walls of the tunnel body 2001, and the first vent 2008 and the second vent 2009 are respectively close to the two ends of the tunnel body 2001, which helps to improve the overall flow of air in the accommodating chamber 2002 and ensure that ventilation can be achieved at all positions in the accommodating chamber 2002.
[0070] In an optional embodiment of the present invention, Figures 3 to 5 As shown, when the road is narrow or the ground space is limited, the ventilation device 1000 can be set on the top of the tunnel main body 2001. While ensuring that the ventilation device 1000 is connected to the tunnel main body 2001, the distance between the two ventilation devices 1000 can be reduced, which is suitable for setting up an underground tunnel when the ground space is limited.
[0071] In another optional embodiment of the present invention, Figures 6 to 8As shown, when the road is wide or not limited by ground space, or when excavation is not suitable or protection is required under the ground, the ventilation device 1000 can be set on the side wall of the pipe gallery body 2001, and the air outlet 102 on the ventilation device 1000 is flush with the top surface of the pipe gallery body 2001, or the air outlet 102 on the ventilation device 1000 is greater than the top surface height of the pipe gallery body 2001 in the vertical direction. While ensuring that the ventilation device 1000 is connected to the pipe gallery body 2001, the excavation depth when the pipe gallery body 2001 is set is minimized. In addition, by arranging the ventilation device 1000 on the side wall of the pipe gallery body 2001, it is possible to avoid setting a mezzanine above the pipe gallery body 2001 to place ventilation facilities (such as: fan 2), greatly reducing the area and height of the ventilation node, thereby reducing the buried depth of the underground pipe gallery, saving costs, and improving the concentration.
[0072] In the present invention, the ventilation device 1000 is set on the top or side wall of the corridor main body 2001 according to actual needs. Of course, the ventilation device 1000 can also be set at any position of the corridor main body 2001 according to the ventilation effect requirements, as long as the expected ventilation effect can be achieved.
[0073] In an optional embodiment of the present invention, Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 As shown, a drainage groove 2010 is provided at the bottom of the accommodating chamber 2002 near a corner, and the drainage outlet of the guide pipe 5 on the ventilation device 1000 extends above and near the drainage groove 2010. The guide pipe 5 can drain the accumulated water in the ventilation chamber 101 into the drainage groove 2010, and the drainage groove 2010 then centrally discharges the collected accumulated water, thereby preventing the accumulation of accumulated water in the pipe gallery body 2001.
[0074] In an optional embodiment of the present invention, Figure 2 As shown, at least a communication pipeline 2005 , a power pipeline 2006 and a heat pipeline 2007 are arranged in the accommodating chamber 2002 .
[0075] Further, such as Figure 2 As shown, a plurality of brackets 2003 are provided on the inner wall of the accommodating chamber 2002 , and the communication lines 2005 and the power lines 2006 are respectively provided on the corresponding brackets 2003 .
[0076] Further, such as Figure 2 As shown, a support base 2004 is provided at the bottom of the accommodating chamber 2002 , and a thermal pipeline 2007 is provided on the support base 2004 .
[0077] The characteristics and advantages of the underground pipe gallery of the present invention are:
[0078] 1. The underground tunnel can be equipped with two ventilation devices 1000 on the two side walls or top of the tunnel body 2001 according to actual needs (such as the width of the street or the ground environment), or the ventilation device 1000 can be arranged at any suitable position on the tunnel body 2001 according to the ventilation effect requirements, ensuring that the air outlet 102 on the ventilation device 1000 is flush with the ground, thereby achieving good ventilation effect while effectively reducing the area of the ventilation node.
[0079] 2. This underground pipe gallery, while meeting the ventilation effect, minimizes the cross-section of the underground pipe gallery as much as possible, reduces the area of ventilation nodes, reduces the cost of the underground pipe gallery, and improves the utilization rate of urban underground space.
[0080] 3. In the underground pipe gallery, the pipe gallery main body 2001 can be set up separately, and the ventilation device 1000 can be installed through the flange structure at the position where ventilation is required. It is suitable for different underground conditions, the installation position is flexible and adjustable, and the application range is wide. Through the setting of the ventilation device 1000 in the present invention, there is no need to set up a mezzanine for accommodating the fan 2 above the pipe gallery main body 2001, which greatly reduces the construction difficulty and improves the integration of the underground pipe gallery.
[0081] Fourth, in the underground tunnel, the guide pipe 5 on the ventilation device 1000 cooperates with the drainage groove 2010 in the tunnel body 2001 to discharge the accumulated water in a centralized manner, thereby solving the problem of accumulated water in the tunnel body 2001.
[0082] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
