Description

Technical Field

[0001] The present invention belongs to the technical field of ventilation devices, and in particular relates to an intelligent tunnel ventilation device and a method for using the same. Background Art

[0002] Ventilation, also known as air exchange, is to use mechanical or natural methods to deliver enough fresh air into the indoor space, and at the same time discharge the dirty air that does not meet the hygienic requirements of the room, so that the indoor air meets the hygienic requirements and the needs of the production process. The various facilities that complete the ventilation work in the building are collectively called ventilation equipment, also known as ventilation equipment.

[0003] Tunnels are engineering buildings buried in the ground, and are a form of human use of underground space. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of a tunnel body and a tunnel door, and the ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications, and drainage facilities. Long tunnels also have special ventilation and lighting equipment.

[0004] Intelligence refers to the property of things that can meet people's various needs with the support of computer networks, big data, the Internet of Things, and artificial intelligence. For example, driverless cars are an intelligent thing that integrates technologies such as sensor Internet of Things, mobile Internet, and big data analysis to actively meet people's travel needs. The reason why it is active is that it is not like traditional cars that require passive human operation and driving.

[0005] The authorization publication number "CN113550776A" records that "a ventilation device for a traffic engineering tunnel relates to the field of tunnel ventilation, including a main air inlet duct, a mounting frame is arranged inside the main air inlet duct, a dust collection device is arranged at the lower end of the mounting frame, and both upper and lower ends of the mounting frame are opened, and the mounting frame is slidably installed inside the main air inlet duct, and two groups of slide rails are arranged inside the mounting frame, and each group of the slide rails is provided with two, and a filter frame is slidably arranged between each group of the slide rails, and a filter screen is fixedly connected inside the filter frame, and a vibration device is arranged on the inner side of the filter screen, and the vibration device includes a driving shaft and a driven shaft. The ventilation device for a traffic engineering tunnel described in the present invention does not need to be manually handled by the filter device by arranging a vibration device, which saves time and labor, and the collection bin located at the lower end can automatically realize the collection function, and the device can maintain a state with high air purification efficiency for a long time."

[0006] The above patent obtains fresh air by filtering through the filter on the mounting frame. The fresh air evenly enters into the tunnel through the branch air inlet pipe, so that the fresh air environment inside the tunnel is maintained. A motor is arranged in the device, and the driving shaft is driven to rotate by the motor. The driving pulley fixedly connected to the driving shaft is connected to the driven pulley through a transmission belt. Therefore, the driving shaft drives the driven shaft to rotate during the rotation of the driving shaft, thereby causing the cams on the driving shaft and the driven shaft to rotate. When the end of the cam that deviates from the axis farther approaches the filter, it can collide with the filter, causing the filter to vibrate. In addition, the slide rail can slide on the slide rod, and when the cam hits the filter, the slide rail can drive the filter frame to move as a whole. With the help of the spring on the upper slide bar, the slide rail can swing back and forth on the slide bar. The back and forth swinging of the filter frame can shake out the dust attached to the filter net more quickly, so that the dust on the filter net can be automatically cleaned without manual cleaning. This not only saves time and effort, but also the filter net after cleaning can still guarantee excellent filtering effect. However, in actual application, the existing ventilation device uses shaking to remove dust in a cold and humid tunnel, which makes the dust in the device easily attached to the filter net, causing the dust to block the filter net, reducing the dehumidification efficiency of the ventilation device, and at the same time making it impossible to adjust the air flow, resulting in the inability to dehumidify part of the tunnel space. For this reason, we propose an intelligent tunnel ventilation device and a method for using it. Summary of the invention

[0022] A method for using an intelligent tunnel ventilation device comprises the following steps:

[0023] S1. Rapid dehumidification:

[0024] A ventilation device is installed in the tunnel. The ventilation device is connected to an external blower through an air duct docking device and a pipeline. When the temperature collector detects that the air humidity in the tunnel is out of the set highest range, the blower is started to extract the moist air in the tunnel to the outside through the exhaust duct to achieve ventilation operation. During the ventilation operation, the air introduced from the outside through the air duct will enter the tunnel through the air inlet duct. When the external air moves between multiple condensing wings, the refrigerant medium stored in multiple exchange tubes is cooled by the wet and cold air in the exhaust duct, so that multiple exchange tubes cool multiple exchange tubes, and multiple condensing wings condense the water vapor in the air in the air inlet duct. After the air in the air inlet duct is condensed and treated with water vapor, the air tends to be dry. Dry air is supplemented in the tunnel through the side exhaust port, the side outlet and the lower outlet to reduce the air humidity in the tunnel, thereby achieving rapid dehumidification of the tunnel.

[0025] S2. Condensate source:

[0026] At the same time, the condensed water vapor falls on the water filter mesh under the blowing of the air flow in the air inlet, slides into the water box along the water filter mesh, the condensation outlet, and the lower exhaust outlet, and falls into the bottom of the water box along the gap between the water box and the support frame, forming pure accumulated water, which is the condensation water source for cleaning the outlet filter plate;

[0027] S3. Adjust the airflow:

[0028] In the process of rapid dehumidification in the tunnel, the operation terminal controls the electric push rod to extend and retract to pull the swing frame to deflect, so that the first differential gear is meshed with the driving gear, so that the output end of the stepper motor drives the driving gear to rotate, and the driving gear drives the first differential gear to rotate by meshing with the first differential gear, and the first differential gear drives the driving pulley to rotate by meshing with the second driven gear, so that the driving pulley and the driven pulley drive the driven pulley to rotate by pulling the transmission belt, and the driven pulley drives the active pull rod to deflect, and the active pull rod pulls the connecting rod, thereby causing the swing rod to deflect 60°, so that the swing rod drives the swing fan blade to deflect 60°, and the dry air is controlled by the deflection of the swing fan blade, and enters the tunnel from the lower air outlet or from the side air outlet, so as to adjust the airflow of the dry air;

[0029] S4, high pressure washing:

[0030] During the ventilation operation, when the air humidity in the tunnel is restored to the normal dry range through the temperature collector, the temperature collector and the blower are shut down. The shutdown of the temperature collector triggers the cleaning program in the operation terminal. The operation terminal starts the water pump. The water pump pumps the accumulated water in the water box through the filter. After being pressurized by the water pump, the water is guided to the nozzle along the outlet pipe, and the outlet filter plate is flushed through the nozzle. At the same time, the operation terminal controls the electric push rod to pull the swing frame to move, so that the second differential gear is meshed with the driving gear and the second driven gear. At the same time, the operation terminal starts the stepper motor, and the output end of the stepper motor drives the driving gear to rotate. The driving gear drives the second differential gear to rotate by meshing with the second differential gear. The second differential gear drives the plastic screw to rotate by meshing with the first driven gear, and then the plastic screw and the plastic slider slide together to promote the reciprocating movement of the nozzle, so that the nozzle performs reciprocating high-pressure flushing on the outlet filter plate for minutes;

[0031] S5, dry;

[0032] After 15 minutes of high-pressure flushing, the operating terminal shuts down the stepper motor and the water pump to stop pumping water to the nozzle and stops moving the plastic screw. The exhaust operation is started for 15 minutes to dry the outlet filter plate in the box.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] In this solution, when the first driven gear drives the plastic screw to rotate by rotating, the plastic screw cooperates with the plastic slider in a sliding manner to push the nozzle to move back and forth in the box, so that the nozzle performs reciprocating high-pressure flushing on the outlet filter plate, thereby changing the shaking dust removal program, and cleaning the outlet filter plate once through ventilation operation, thereby effectively removing dust attached to the outlet filter plate, avoiding clogging of the outlet filter plate, and improving the dehumidification efficiency of the ventilation device.

[0035] In this solution, the operating terminal controls the electric push rod to pull the swing frame to move, so that the second differential gear is meshed with the driving gear and the second driven gear. At the same time, the operating terminal starts the stepper motor, and the output end of the stepper motor drives the driving gear to rotate. The driving gear drives the second differential gear to rotate by meshing with the second differential gear. The second differential gear drives the plastic screw to rotate by meshing with the first driven gear, and then the plastic screw and the plastic slider slide together to push the reciprocating movement of the nozzle, and control the nozzle to perform reciprocating high-pressure flushing on the outlet filter plate for minutes, thereby changing the shaking dust removal method and improving the dust removal efficiency.

[0036] In this solution, when the outside air moves between multiple condensing fins, the refrigerant medium stored in the multiple exchange tubes is cooled by the wet and cold air in the exhaust duct, so that the multiple exchange tubes cool down the multiple exchange tubes, and the multiple condensing fins condense the water vapor in the air in the inlet duct. The condensed water vapor falls on the water filter mesh under the blowing of the airflow in the inlet duct, slides into the water box along the water filter mesh, the condensation outlet, and the lower exhaust outlet, and falls into the bottom of the water box along the gap between the water box and the support frame, forming pure accumulated water, which is a condensed water source for cleaning the outlet filter plate, which not only ensures the dryness of the air entering the tunnel, but also provides a clean water source for cleaning the outlet filter plate.

[0037] In this scheme, during the process of rapid dehumidification of the tunnel, the operation terminal controls the electric push rod to extend and retract to pull the swing frame to deflect, so that the first differential gear is meshed with the driving gear, so that the output end of the stepper motor drives the driving gear to rotate, and the driving gear drives the first differential gear to rotate by meshing with the first differential gear, and the first differential gear drives the driving pulley to rotate by meshing with the second driven gear, so that the driving pulley and the driven pulley drive the driven pulley to rotate by pulling the transmission belt, and the driven pulley drives the active pull rod to deflect, and the active pull rod pulls the connecting rod to deflect the swing rod by 60°, so that the swing rod drives the swing fan blade to deflect by 60°, and the dry air is controlled by the deflection of the swing fan blade, and enters the tunnel from the lower air outlet or from the side air outlet, so as to adjust the airflow of the dry air, so that the dry air flows through every corner of the tunnel, and the tunnel is fully dehumidified.

[0075] A method for using an intelligent tunnel ventilation device comprises the following steps:

[0076] S1. Rapid dehumidification:

[0077] The ventilation device is installed in the tunnel, and the ventilation device is connected with the external blower through the air duct docking device 53 and the pipeline. When the temperature collector 34 detects that the air humidity in the tunnel is out of the set highest range, the blower is started to extract the moist air in the tunnel to the outside through the exhaust duct to realize the ventilation operation. During the ventilation operation, the air introduced from the outside through the air duct 33 will enter the tunnel through the air inlet duct. When the external air moves between the multiple condensing wings 38, the refrigerant medium stored in the multiple exchange tubes 39 is cooled by the wet and cold air in the exhaust duct, so that the multiple exchange tubes 39 cool the multiple exchange tubes 39, so that the multiple condensing wings 38 condense the water vapor in the air in the air inlet duct.

The dry air is supplemented in the tunnel through the side exhaust port 41, the side outlet 47 and the lower outlet 8 to reduce the air humidity in the tunnel, thereby realizing rapid dehumidification of the tunnel.

[0078] S2. Condensate source:

[0082] S3, high pressure washing:

[0083] During the ventilation operation, when the air humidity in the tunnel monitored by the temperature collector 34 returns to the normal dry range, the temperature collector 34 and the blower are shut down. The shutdown of the temperature collector 34 triggers the cleaning program in the operation terminal 46. The operation terminal 46 starts the water pump 12. The water pump 12 pumps the accumulated water in the water box 6 through the filter 32. After the water pump 12 is pressurized, it is guided to the nozzle 30 along the outlet pipe 31.

The second differential gear 18 drives the plastic screw 28 to rotate by meshing with the first driven gear 19, and then the plastic screw 28 and the plastic slider 29 are slidably matched, pushing the reciprocating movement of the nozzle 30, so that the nozzle 30 performs a reciprocating high-pressure washing on the outlet filter plate 37 for 5 minutes;

[0084] S4, drying;

[0085] After 5 minutes of high-pressure flushing, the operation terminal 46 shuts down the stepper motor 13 and the water pump 12 to stop pumping water to the nozzle 30 and stops moving the plastic screw 28. The outlet filter plate 37 in the box 3 is dried by starting a 3-minute exhaust operation.
