[0018] 1. The pressurized ventilation pipeline structure and air conditioning system of the narrow and long space of the subway, the flow control components, air pump, water pump, three-way valve, air guide components, condensation components and other structures constitute the pipeline structure, and the air guide components are designed to be narrow and long, which can realize the temperature control, humidity adjustment, exhaust and dispersion of air, and comprehensive sterilization and disinfection work inside the narrow and long subway station as needed, ensuring the economic benefits of the use of the pipeline structure.

[0019] 2. The pressurized ventilation pipeline structure and air conditioning system of the narrow and long space of the subway are characterized by a long air guide pipe, and multiple exhaust boxes are respectively arranged on both sides of the long air guide pipe. The cold air or the hot air is guided by an air guide component composed of a solenoid valve, a diversion vertical box, four curved pipes of different lengths, a long air guide pipe and multiple exhaust boxes. After being discharged, it presents a long and narrow wind domain, and directly discharges cold air or the hot air to various parts inside the narrow and long subway station, ensuring that the temperature inside the narrow and long subway station is adjusted evenly and quickly.

[0020] 3. The pressurized ventilation duct structure and air conditioning system of the narrow and long space of the subway. After the cold air or warm air enters the long air guide tube, it contacts multiple metal plates. The water condensed from the metal plates drops into the collection frame, and the condensed water is collected and discharged, reducing the dripping phenomenon generated by the air guide component in the process of discharging cold air or warm air, reducing the impact on people in the subway station, avoiding water accumulation in the long air guide tube due to the flow of cold air or warm air, and ensuring that the inside of the long air guide tube is clean.

[0021] 4. The pressurized ventilation pipeline structure and air conditioning system of the narrow and long space of the subway are connected with various parts of the internal space of the narrow and long subway station through multiple circular holes and multiple small holes. The gas inside the diversion vertical box comes directly from various parts inside the narrow and long subway station, which quickly discharges the air inside the narrow and long subway station, increases the pressure difference between the inside of the subway station and the outside, and increases the air flow speed, which has the effect of efficient exhaust and ventilation in the narrow and long subway station.

[0022] 5. The pressurized ventilation pipeline structure and air conditioning system of the narrow and long space of the subway, after the water pump works, is discharged into the long air guide tube through the diversion vertical box and four elbows, and at this time, the atomizing nozzle in the flow control component is set at the bottom of the elbow. The water transported by the elbow is first atomized by the atomizing nozzle before it can enter the long air guide tube. The water mist is guided into various parts of the narrow and long subway station through the air guide component, which can quickly humidify various parts inside the subway station and improve the speed of comprehensive humidification inside the subway station.

[0023] 6. The pressurized ventilation pipeline structure and air conditioning system in the narrow and long space of the subway provide disinfectant or deodorant to the water pump through the normally closed end of the three-way valve. When disinfectant is provided to the water pump, the atomized disinfectant is transported to multiple locations inside the subway station by the air guide component, so as to carry out more comprehensive disinfection and sterilization inside the subway station and reduce the labor cost investment required for cleaning the subway station.

[0024] 7. The pressurized ventilation pipeline structure and air conditioning system of the narrow and long space of the subway, the flow control component seals the bottom of the bent pipe, and the deodorant entering the diversion vertical box cannot enter the long air guide tube through the bent pipe. The opened flow control valve guides the deodorant in the diversion vertical box to the collection frame. The deodorant enters multiple collection frames through square pipes and multiple water flow troughs, so that the deodorant enters various positions inside the long air guide tube under the guidance of the condensation component to remove the odor inside the long air guide tube.

[0038] The embodiment of the present invention provides a pressurized ventilation pipeline structure for a narrow and long space in a subway and an air conditioning system thereof.

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9, including an air intake duct 8 and a controller 2, an air guide component is provided at one end of the air intake duct 8, the air guide component is used to spread the cold and hot air transported by the air intake duct 8 into the narrow and long space of the subway station, the air guide component includes a solenoid valve 7, a shunt vertical box 6, four elbows 15 of different lengths, a long air guide tube 1 and multiple exhaust boxes 5, a plurality of small holes 31 are provided at the bottom of the long air guide tube 1, a plurality of smoke alarms 3 are fixedly connected to the bottom of the long air guide tube 1, a shunt pipe 4 is fixedly connected between the long air guide tube 1 and the exhaust box 5, a plurality of circular holes 30 are provided at the bottom of the exhaust box 5, the shunt vertical box 6 is fixedly connected to the top of the long air guide tube 1, the solenoid valve 7 is fixedly connected between the shunt vertical box 6 and the air intake duct 8, and the four elbows 15 are respectively fixedly connected to the two ends of the shunt vertical box 6 The controller 2 is fixedly connected to one side of the diversion vertical box 6 between the side and the long air guide tube 1; a condensation component is arranged inside the long air guide tube 1, and the condensation component includes a square pipe 26, an electric push rod 25, multiple collection frames 22, and multiple metal plates 21. Multiple water flow grooves 27 are opened on the outside of the square pipe 26; an air pump 10, a water pump 11, and a three-way valve 12 are arranged on the top of the diversion vertical box 6, and a flow control valve 23 is arranged between the diversion vertical box 6 and one of the collection frames 22; a flow control component is arranged on one side of the bottom of the bent pipe 15, and the flow control component includes a pneumatic cylinder 20, an atomizing nozzle 19, a rubber block 17 and a square frame 16. The atomizing nozzle 19 is arranged at the bottom of the bent pipe 15, and the flow control component is used to adjust the state of the bent pipe 15 entering the liquid inside the long air guide tube 1.

[0040] Specifically, when the controller 2 controls the solenoid valve 7 to open, the air intake pipe 8 infuses cold air or warm air (cold air in summer, warm air in winter) into the inside of the shunt vertical box 6 through the solenoid valve 7, and the warm air or cold air enters various positions inside the long air guide tube 1 through four bent pipes 15 fixed between the shunt vertical box 6 and the long air guide tube 1. In addition, a plurality of small holes 31 are opened at the bottom of the long air guide tube 1, and a plurality of round holes 30 are opened at the bottom of the plurality of exhaust boxes 5 fixed to the long air guide tube 1 through a plurality of shunt pipes 4.

[0041] Therefore, the cold air or warm air entering the long air guide tube 1 is discharged through multiple small holes 31 and multiple round holes 30, and the long air guide tube 1 is in the shape of a long strip, and multiple exhaust boxes 5 are respectively arranged on both sides of the long air guide tube 1. The cold air or warm air is guided by the air guide assembly composed of the solenoid valve 7, the diversion vertical box 6, four curved pipes 15 of different lengths, the long air guide tube 1 and multiple exhaust boxes 5. After being discharged, it presents a long and narrow wind domain, and directly discharges cold air or warm air at various parts inside the long and narrow subway station, ensuring that the temperature inside the long and narrow subway station is adjusted uniformly and quickly. By controlling the temperature difference between the inside and outside of the long and narrow subway station to cause the air pressure difference, it plays a role in increasing the air convection between the long and narrow subway station and the outside world, and speeding up the air discharge speed inside the long and narrow subway station. This is the temperature control work inside the subway station.

[0042] In addition, a condensation component is provided inside the long air guide tube 1 (for details of the operation of the condensation component, see below). After the cold air or the warm air enters the long air guide tube 1, it contacts the multiple metal plates 21, and condensation occurs due to the temperature difference. The water condensed from the metal plates 21 drops into the collection frame 22, and the condensed water is collected and discharged, thereby reducing the dripping phenomenon generated during the discharge of cold air or warm air by the air guide component, reducing the impact on the personnel in the subway station, and avoiding water accumulation inside the long air guide tube 1 due to the flow of cold air or warm air, thereby ensuring that the inside of the long air guide tube 1 is clean.

[0043] And control the vacuum pump 10 to work, the working vacuum pump 10 extracts the internal gas of the shunt vertical box 6, and the shunt vertical box 6 is connected to the inside of the long air guide tube 1 through four elbows 15, and the long air guide tube 1 is connected to various parts of the internal space of the narrow and long subway station through multiple round holes 30 and multiple small holes 31. Therefore, the internal gas of the shunt vertical box 6 comes directly from various parts inside the narrow and long subway station, and quickly discharges the internal air of the narrow and long subway station, increasing the pressure difference between the inside of the subway station and the outside, increasing the air flow speed, and achieving the effect of efficient exhaust and ventilation in the narrow and long subway station. This is the internal ventilation work of the subway station.

[0044] Similarly, the water pump 11 is controlled to work, and the three-way valve 12 is always open and connected to the water supply system of the subway station. After the water pump 11 works to pump water, it is discharged into the long air pipe 1 through the diversion vertical box 6 and the four bends 15. At this time, the atomizing nozzle 19 in the flow control component (the details of the flow control component are as follows) is set at the bottom of the bend 15. The water transported by the bend 15 is first atomized by the atomizing nozzle 19 before it can enter the long air pipe 1. The water mist is guided into various parts of the narrow subway station through the air guide component, which can quickly humidify various parts inside the subway station and improve the speed of comprehensive humidification inside the subway station. This is the humidification work of the subway station.

[0045] Similarly, the normally closed end of the three-way valve 12 is controlled to be opened, and disinfectant or deodorant is provided to the water pump 11 through the normally closed end of the three-way valve 12. When the disinfectant is provided to the water pump 11, the disinfectant transported by the water pump 11 to the inside of the long air guide tube 1 through the elbow 15 is atomized by the atomizing nozzle 19. The atomized disinfectant is transported to multiple locations inside the subway station by the air guide component, and the inside of the subway station is disinfected and sterilized more comprehensively, reducing the labor cost investment required for cleaning the subway station.

[0046] When the subway station is disinfected, the condensation assembly is controlled to work, and the electric push rod 25 works to push the collection frame 22 to move, and the multiple collection frames 22 are fixed as a whole through the square pipe 26, so the electric push rod 25 pushes the multiple collection frames 22 to move, and the multiple collection frames 22 move to the top of the multiple small holes 31. At this time, the atomized disinfectant can only be discharged through the circular holes 30 opened by the multiple exhaust boxes 5, ensuring that the atomized disinfectant is dispersed to various parts inside the subway station. This is the internal disinfection work of the subway station.

[0047] When deodorant is supplied to the water pump 11 through the three-way valve 12, the control flow control component and the flow control valve 23 work simultaneously, and the flow control component seals the bottom of the bend pipe 15. At this time, the deodorant entering the diversion vertical box 6 cannot enter the long air guide tube 1 through the bend pipe 15. The opened flow control valve 23 guides the deodorant in the diversion vertical box 6 to the collection frame 22.

[0048] Furthermore, the plurality of water troughs 27 provided in the square pipe 26 are respectively arranged inside the plurality of collection frames 22, so that the deodorant enters the plurality of collection frames 22 through the square pipe 26 and the plurality of water troughs 27, and the deodorant enters various positions inside the long air guide tube 1 under the guidance of the condensation component, and removes the odor inside the long air guide tube 1. This is the deodorization work inside the long air guide tube 1.

[0049] The pipeline structure is composed of flow control components, vacuum pump 10, water pump 11, three-way valve 12, air guide components, condensation components and other structures. The air guide components are designed to be long and narrow, and can achieve temperature control, humidity adjustment, exhaust and comprehensive sterilization and disinfection inside the long and narrow subway station as needed, ensuring the economic benefits of the use of the pipeline structure.

[0050] Different numbers of flow control components at different positions can be controlled to work as needed. The pneumatic cylinder 20 works to push the square frame 16 to move, and the moving square frame 16 drives the rubber block 17 to move. The rubber block 17 moves to the bottom of the curved pipe 15 to block the bottom of the curved pipe 15. At the same time, the metal plate 21 fixed on the outside of the square frame 16 moves to contact the inner wall of the collecting frame 22. At this time, the partition plate formed by the metal plate 21 and the collecting frame 22 separates the inside of the long air guide tube 1.

[0051] The four flow control components are arranged from left to right as flow control component 1, flow control component 2, flow control component 3 and flow control component 4. After the control components 2, 3 and 4 are in operation, the three flow control components cut off the connection between the top bend pipe 15 and the long air guide tube 1. At this time, the four flow control components divide the inside of the long air guide tube 1 into multiple spaces. At this time, only the bend pipe 15 at the top of the first flow control component can transport liquid to the inside of the long air guide tube 1. The liquid is atomized by the atomizing nozzle 19, or the long air guide tube 1 is infused with cold air or heating. The cold air or heating and the water mist are discharged through the multiple shunt pipes 4 and multiple small holes 31 distributed between the first flow control component and the second flow control component.

[0052] Similarly, the working vacuum pump 10 can only extract the air inside the long air guide tube 1 through a flow control component and the curved pipe 15 at the top thereof, so as to achieve the effects of temperature control, humidity control, disinfection and exhaust at a local position inside the narrow and long subway station. The flow control components at different positions can adjust the corresponding spatial environment inside the subway station in a targeted manner. The staff can control the opening degree of the subway station according to the flow of people at the location of the subway station, and adapt to places such as tourist attractions where the flow of people is divided into off-season and peak season. This is the fixed-point exhaust work inside the subway station.

[0053] A plurality of smoke alarms 3 are fixedly connected to the bottom of the long gas guide tube 1. When a fire occurs inside the subway station, the smoke alarm 3 sounds an alarm. The controller 2 electrically connected to the smoke alarm 3 controls the water pump 11 and the flow control component to work in reverse. At this time, the pneumatic cylinder 20 drives the square frame 16 away from the curved pipe 15, so that the bottom of the curved pipe 15 loses the obstruction of the atomizing nozzle 19. At this time, the water pump 11 directly fills the interior of the long gas guide tube 1 with water through the diversion vertical box 6 and the plurality of curved pipes 15. The water is sprayed into the subway station through the plurality of circular holes 30 and the small holes 31, and the fire is extinguished inside the subway station, thereby ensuring the safety inside the subway station and improving the practicality of the pipeline structure. In addition, the flow control component at the top of the fire point can be controlled to work in reverse, and the other flow control components can work normally to achieve fixed-point fire extinguishing. This is the automatic fire extinguishing work inside the subway station.

[0054] By cooperating with multiple flow control components and air guide components, the temperature and humidity of local locations inside the subway station can be controlled as needed, thereby reducing the resource investment required for the operation of the subway station when the flow of people is small, and improving the economic benefits of the use of the pipeline structure composed of the flow control components, vacuum pump 10, water pump 11, three-way valve 12, air guide components, condensation components and other structures inside the subway station.

[0055] Please refer again Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 , an installation box 9 is fixedly connected to the top of the diversion vertical box 6, and a water-gas dual-purpose valve 14 is fixedly connected to the installation box 9, the water pump 11 and the air pump 10, the three-way valve 12 is fixedly connected to the water inlet end of the water pump 11, and the normally closed end of the three-way valve 12 is fixedly connected to the liquid supply pipeline 13, the flow control valve 23 is fixedly connected between the air guide long tube 1 and the diversion vertical box 6, and a rubber tube 24 is fixedly connected between the flow control valve 23 and the collecting frame 22, and the rubber tube 24 is set in an L shape. Multiple collecting frames 22 are fixedly connected to the outside of the square pipe 26, and multiple water flow troughs 27 are respectively arranged in multiple collecting frames 22. An electric push rod 25 is fixedly connected between one of the collecting frames 22 and the air guide long tube 1, and multiple metal plates 21 are respectively arranged on the top of multiple collecting frames 22. A waste valve 29 is fixedly connected to one end of the air guide long tube 1, and a telescopic tube 28 is fixedly connected between the square pipe 26 and the waste valve 29.

[0056] Specifically, the air guide assembly works as follows:

[0057] A water-gas dual-purpose valve 14 is fixedly connected to the bottom of the air pump 10 and the water pump 11. When the air pump 10 or the water pump 11 is working, the water-gas dual-purpose valve 14 at the bottom thereof works synchronously, so that the air pump 10 or the water pump 11 draws air or injects liquid into the installation box 9 through the opened water-gas dual-purpose valve 14.

[0058] The installation box 9 is fixedly connected to the top of the diversion vertical box 6, and four elbows 15 are fixedly connected between the diversion vertical box 6 and the long gas pipe 1, so the inside of the diversion vertical box 6 is connected to the inside of the long gas pipe 1 through the four elbows 15. The diversion vertical box 6, the installation box 9, and the four elbows 15 form a pipeline structure to connect the water pump 11 and the air pump 10 to the inside of the long gas pipe 1 to meet the flow of gas and liquid. The normally open end of the three-way valve 12 is used to connect the internal water supply system of the subway station, and the liquid supply pipeline 13 fixed to the normally closed end of the three-way valve 12 is used to connect the poison or deodorant system.

[0059] The condensation assembly works as follows:

[0060] After the cold air or the warm air enters the interior of the long air guide tube 1 through the curved pipe 15, it contacts with the multiple metal plates 21 and condenses due to the temperature difference. The water condensed from the metal plates 21 drops into the collection frame 22, and the condensed water is collected. In addition, the multiple water troughs 27 provided in the square pipe 26 are respectively arranged inside the multiple collection frames 22, so that the water inside the collection frame 22 can enter the interior of the square pipe 26 through the water troughs 27.

[0061] One end of the square pipe 26 is fixed to the waste valve 29 through a telescopic tube 28 , so after the waste valve 29 is controlled to open, the liquid inside the square pipe 26 is discharged by the waste valve 29 through the guidance of the telescopic tube 28 .

[0062] After the electric push rod 25 fixed to the collecting frame 22 works, it pushes one collecting frame 22 to move, and the moving collecting frame 22 moves multiple collecting frames 22 through the square pipe 26, so that the multiple collecting frames 22 block and seal the multiple small holes 31. The telescopic tube 28 that can be extended and retracted meets the movement requirements of the square pipe 26. Similarly, a rubber tube 24 with a certain elasticity that can be extended and retracted is fixedly connected between the flow control valve 23 and the collecting frame 22, so the flow control valve 23 will not affect the movement of the collecting frame 22.

[0063] Please refer again Figure 1 , Figure 5 , Figure 6 and Figure 7The pneumatic cylinder 20 is fixedly connected to the inside of the long air guide tube 1, the square frame 16 is fixedly connected to one end of the pneumatic cylinder 20, the rubber block 17 is fixedly connected to the inside of the square frame 16, a through hole 18 is opened on one side of the top of the rubber block 17, and the atomizing nozzle 19 is arranged at the bottom of the through hole 18 and fixedly connected to the square frame 16, wherein four metal plates 21 are fixedly sleeved on the outside of the four square frames 16 respectively, and the remaining metal plates 21 are fixedly connected to the top of the inner cavity of the long air guide tube 1.

[0064] Specifically, the flow control component works as follows:

[0065] Under normal circumstances, the through hole 18 opened by the rubber block 17 is set at the bottom of the elbow 15, and the rubber block 17 with a certain elasticity contacts the long air guide tube 1 to play a sealing role. The liquid transported by the elbow 15 enters the interior of the atomizing nozzle 19 through the through hole 18 and is atomized by the atomizing nozzle 19.

[0066] When the pneumatic cylinder 20 is working, the pneumatic cylinder 20 pushes the square frame 16 to move, so that the square frame 16 and the metal plate 21 fixedly mounted outside the square frame 16 move. At this time, the square frame 16 drives the rubber block 17 to move, so that the position without a slot on the top of the rubber block 17 moves to the bottom of the elbow 15, thereby sealing the bottom of the elbow 15.

[0067] When the flow control assembly works in reverse, the pneumatic cylinder 20 drives the frame 16 away from the elbow 15, so that the inside of the elbow 15 loses its obstruction. At this time, the liquid transported inside the elbow 15 directly enters the long air guide tube 1, ensuring the speed of replenishing the liquid inside the long air guide tube 1 to meet the fire extinguishing needs.

[0068] Please refer again Figure 2 Fig.10 , Fig.11 and Fig.12 The controller 2 includes a data receiving end 201, a processor 202, an identification module 203, a control module 204 and a time control module 209. The output end of the processor 202 is electrically connected to the identification module 203 and the control module 204. The output end of the identification module 203 is electrically connected to the control module 204. The output end of the time control module 209 is electrically connected to the control module 204. The output end of the control module 204 is electrically connected to a ventilation instruction 205, a humidity control instruction 206, a temperature control instruction 207, and a deodorization instruction 208. The output end of the data receiving end 201 is electrically connected to the processor 202. The output end of the control module 204 is electrically connected to an alarm module 210 and a communication module 211. The output end of the control module 204 is electrically connected to the water pump 11 and the pneumatic cylinder 20. The output end of the smoke alarm 3 is electrically connected to the processor 202.

[0069] Specifically, after the data receiving end 201 receives the temperature control command or humidity control command sent by the staff, the processor 202 performs calculation analysis on the temperature control command. The processor 202 decodes the temperature control command into a temperature reduction range or a temperature increase range according to the existing temperature value and transmits it to the identification module 203. The identification module 203 makes the control module 204 work according to the temperature increase range or the temperature reduction range. The control module 204 generates a temperature control instruction 207 according to the temperature increase range or the temperature reduction range. The temperature control instruction 207 controls the solenoid valve 7 and the pneumatic cylinder 20 to work and perform temperature control work inside the subway station. (For details of the temperature control work inside the subway station, please see above).

[0070] Similarly, the processor 202 decomposes the humidity control command into a humidity rising range or a humidity falling range. The identification module 203 enables the control module 204 to generate a humidity control instruction 206 or a ventilation instruction 205 according to the humidity rising range or the humidity falling range. The ventilation instruction 205 controls the water pump 11 to ventilate the inside of the subway station (see above for details of the ventilation work inside the subway station), discharge the moisture inside the subway station, and dehumidify. The humidity control instruction 206 controls the water pump 11 and the electric push rod 25 to humidify the subway station (see above for details of the humidification work of the subway station). The temperature and humidity inside the narrow and long subway station can be quickly adjusted according to different seasons to improve the user experience of the subway station.

[0071] And the deodorization command is sent to the controller 2 at a regular interval, and the control module 204 electrically connected to the processor 202 generates a deodorization instruction 208, so that the deodorization instruction 208 controls the three-way valve 12 to provide a deodorant to the water pump 11, and deodorizes the inside of the long air guide tube 1 (for details of the deodorization work inside the long air guide tube 1, please see above), or controls the three-way valve 12 to provide a disinfectant to the water pump 11, and performs a comprehensive disinfection work inside the subway station (for details of the disinfection work inside the subway station, please see above).

[0072] When the smoke alarm 3 detects a fire in the subway station, the processor 202 electrically connected to the smoke alarm 3 directly operates the control module 204, so that the control module 204 controls the water pump 11 and the pneumatic cylinder 20 to operate, and automatically extinguishes the fire inside the subway station (for details of the automatic fire extinguishing inside the subway station, please see above). At the same time, the control module 204 controls the alarm module 210 to issue a fire alarm and remind people to move to the bottom of the exhaust box 5. At the same time, the communication module 211 sends the fire alarm to the staff, reminding the corresponding staff to evacuate the crowd.

[0073] The data receiving terminal 201, processor 202, identification module 203, control module 204 and other structures inside the controller 2 constitute a control system, which controls the pipeline structure composed of the flow control component, vacuum pump 10, water pump 11, three-way valve 12, air guide component, condensation component and other structures, and controls the pipeline structure to achieve functions such as temperature control, humidity control, disinfection, and exhaust. The setting of the time control module 209 can enable the control system to automatically control the pipeline structure at a fixed time to achieve corresponding functions, thereby improving the economic benefits of pipeline structure construction.
