Description

Technical Field

[0001] This invention relates to the field of ventilation equipment technology, specifically an energy-saving and low-carbon ventilation equipment for subway tunnels. Background Technology

[0002] Subway tunnels are densely populated, and passengers' breathing produces carbon dioxide. At the same time, the operation of trains also produces some exhaust gas. By installing ventilation equipment inside the subway tunnel, polluted air can be discharged from the tunnel and fresh air can be introduced, thereby improving the air and environmental quality inside the subway tunnel. Commonly used ventilation equipment mainly includes ventilation ducts. The ventilation ducts are equipped with forward and reverse rotating fans. By changing the direction of the fan blades on the fans, the ventilation ducts can ventilate the tunnel. While most existing ventilation systems can perform ventilation functions, they are not easy to automatically detect and maintain during the ventilation process. For example, a faulty starting capacitor in the fan motor can lead to insufficient fan blade speed, and a clogged filter in the duct can obstruct air from entering the duct. In these situations, although the ventilation system is performing ventilation operations, more energy is wasted on the ineffective operation of the motor. Therefore, it is necessary to design a ventilation system that can also perform detection and maintenance functions. Through timely detection and maintenance, the ventilation system can be ensured to operate in the best condition, reducing unnecessary energy consumption. Summary of the Invention

[0003] The purpose of this invention is to provide an energy-saving and low-carbon ventilation device for subway tunnels to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An energy-saving and low-carbon ventilation device for subway tunnels includes: Two air ducts, each including an air exchange duct, with filter boxes fixedly connected to both ends of the air exchange duct; Two fans, one for forward and one for reverse rotation, are installed inside the air duct at corresponding positions. Multiple filter components are installed inside the filter box at corresponding positions. Each filter component includes two rollers that are rotatably connected to the filter box, and a filter belt is driven between the two rollers. A maintenance box, the maintenance box including an I-shaped plate fixed between two air ducts; Two detection mechanisms are fixed on the top surface of the C-shaped plate. The detection mechanism determines whether the filter belt is clogged or the fan is malfunctioning by detecting the air volume inside the air duct. The detection mechanism includes a slide rail, on which a movable seat is slidably connected. An air volume meter is rotatably connected to the top of the movable seat. A transmission frame and a motor are arranged on the outside of the movable seat to drive the air volume meter to adjust its position.

[0005] Furthermore, a silencer is fixedly connected to the end of the filter box away from the air exchange cylinder, and a protective net is fixedly installed at the opening of the silencer.

[0006] Furthermore, the reversible fan includes a motor that is fixedly connected to the ventilation cylinder, and the output end of the motor is fixed with fan blades.

[0007] Furthermore, the bottom of the filter box is fixed with a motor three that can drive the rollers at the corresponding positions to rotate, and the outer side of the rollers is hollowed out.

[0008] Furthermore, the filter belt is provided with a mesh area and through holes.

[0009] Furthermore, the slide rail is fixedly connected to the U-shaped plate, and the top of the movable seat is rotatably connected to a support shaft that is fixedly connected to the air volume meter.

[0010] Furthermore, a gear is fixed to the outside of the support shaft, the transmission frame and the motor are both fixedly connected to the U-shaped plate, and a rack that meshes with the gear is embedded and fixed in the middle of the transmission frame.

[0011] Furthermore, the output end of the second motor is fixed with a drive wheel, and a transmission column is rotatably connected to the outer side of the drive wheel. The transmission column is inserted and fixed to the movable seat.

[0012] Furthermore, the top surface of the shaped plate is fixed with a partition, the opening of the shaped plate is detachably and fixed with a cover plate, and the filter belt is arranged in the space between the shaped plate and the partition.

[0013] Furthermore, both ends of the C-shaped plate are provided with cleaning components. The cleaning components include pipes that are driven and installed with the detection mechanism. One end of the pipe is driven and connected to a circular plate. A brush disc is sleeved and fixed on the outer side of the circular plate. The brush disc can clean the filter belt.

[0014] Compared with the prior art, the beneficial effects of the present invention are: A slide rail is fixed inside the maintenance box, and a movable seat slides on the slide rail. The movable seat is rotatably mounted with an air volume meter via a support shaft. A transmission frame and a second motor are set on the outside of the air volume meter to adjust its position. The output end of the second motor drives the drive wheel to rotate, causing the transmission column to push the movable seat towards one end of the slide rail. The movable seat moves synchronously with the air volume meter towards the end of the slide rail. During the movement, the gear on the support shaft meshes with the rack on the transmission frame, causing the support shaft to rotate the air volume meter by 90 degrees, so that the air volume meter can be aligned with the detection hole on the ventilation cylinder. As the movable seat continues to move with the air volume meter towards the end of the slide rail, the air volume meter is inserted into the ventilation cylinder through the detection hole. The air volume meter can detect the air volume flowing inside the ventilation cylinder. When the air volume is lower than the preset standard air volume value, it indicates that the ventilation of the ventilation cylinder is not smooth.

[0015] When the anemometer detects low airflow after entering the ventilation duct, the motor drives the rollers to drive the filter belt, moving the through-hole area on the filter belt into the filter box. This ensures that the airflow direction of the reversible fan is not obstructed by the filter belt, preventing airflow from being blocked by impurities. If the anemometer reading is still low after the filter belt is removed from the air inlet of the ventilation duct, it indicates that the low airflow inside the ventilation duct is not caused by filter belt blockage, but by a malfunction of the reversible fan. This allows users to detect potential factors affecting ventilation volume in a timely manner. Once a malfunction is identified as a reversible fan malfunction, the machine can be stopped and repaired promptly, effectively preventing energy waste on the ineffective operation of the reversible fan and contributing to energy-saving and low-carbon operation of the ventilation equipment. If the airflow measurement result shows an increase in airflow after the filter belt is removed, it indicates that the blockage in the mesh area of ​​the filter belt is causing poor airflow in the duct. In this case, the blockage area of ​​the filter belt has been moved to the brush plate position during the aforementioned transmission detection process. At this point, the motor drive on the detection mechanism can rotate the brush plate to automatically clean the filter belt. After the filter belt is cleaned, the two rollers rotate in opposite directions to move the mesh area of ​​the filter belt back to the filter box position. Then, observe the airflow measurement value of the airflow meter. If the value is normal, it means that the filter can continue to be used after cleaning. If the value is still low, it means that the filter belt needs to be disassembled, cleaned, or replaced, thereby achieving automatic detection and maintenance of the filter belt.

[0016] By installing a filter belt at each end of the ventilation duct, the mesh areas of the two filter belts can alternately block the ends of the ventilation duct. This allows the other filter belt to temporarily replace the filter belt while cleaning one filter belt, enabling the ventilation duct to be cleaned without stopping the machine. It also ensures that when the fan changes its rotation direction to draw air from either end of the ventilation duct, the filter belt will intercept impurities in the air. By combining the two ventilation ducts, during ventilation operations, one ventilation duct can draw air from the subway tunnel, while the other ventilation duct delivers fresh air from the outside into the subway tunnel, which helps to quickly ventilate the subway tunnel.

[0017] By installing two detection mechanisms inside the maintenance box, the airflow meters on both mechanisms can be simultaneously inserted into the same air duct, with the two airflow meters arranged at opposite ends of the fan blades. By comparing the airflow measurement results of the two airflow meters, the airflow characteristics of the fan can be evaluated, thereby optimizing the fan blades. Specific operations include adjusting the fan blade angle, the number of fan blades, optimizing the flow channel shape, and adding guide vanes. These optimization measures can significantly improve the operating efficiency of the fan, reduce energy waste, and achieve energy-saving and low-carbon effects. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figure 1 - Figure 8In this embodiment of the invention, an energy-saving and low-carbon ventilation device for subway tunnels includes two ventilation ducts 100. Each ventilation duct 100 includes an air exchange duct 110, with filter boxes 120 fixedly connected to both ends. A reversible fan 200 is fixedly installed inside the air exchange duct 110, capable of drawing or expelling air through it. A filter assembly 300 is fixedly installed inside the filter box 120, filtering impurities entering and exiting the ventilation duct 100. The filter assembly 300 includes two rollers 310 rotatably connected to the filter box 120, with a filter belt 320 drivingly connected between the two rollers 310. A connecting belt is fixedly connected between the two ventilation ducts 100. The protective box 400 includes an I-shaped plate 410 fixedly connected to both air ducts 100. Both ends of the top surface of the I-shaped plate 410 are provided with detection mechanisms 500. The detection mechanisms 500 determine whether the filter belt 320 is blocked or the forward and reverse fan 200 is malfunctioning by detecting the air volume inside the air duct 100. The detection mechanism 500 includes a slide rail 510. A movable seat 520 is slidably connected to the top of the slide rail 510. An air volume meter 540 is rotatably connected to the top of the movable seat 520. A transmission frame 550 is arranged on the outside of the movable seat 520 to drive the air volume meter 540 to rotate and adjust its position. A motor 570 is arranged on the outside of the transmission frame 550 to drive the movable seat 520 to slide along the slide rail 510.

[0022] Specifically, a filter belt 320 is connected to the filter box 120 of the air duct 100, and the filter belt 320 has through holes 322 for filtration effect. A detection mechanism 500 is set on the outside of the air duct 100. The motor 570 on the detection mechanism 500 drives the drive wheel 580 to rotate, so that the transmission column 560 carries the moving seat 520 to slide along the slide rail 510. The moving seat 520 carries the air volume meter 540 to slide along the slide rail 510, so that the air volume meter 540 can enter the ventilation duct 110 of the air duct 100. The air volume meter 540 can be detected in time. Measure the airflow inside the air duct 100. When the measured airflow value is lower than the standard airflow value, the through-hole 322 area on the filter belt 320 can be moved to the air inlet end of the air duct 100. If the airflow value of the anemometer 540 is still low, it may indicate a malfunction of the reversible fan 200. If the anemometer 540 value is normal, it indicates that the filter belt 320 is blocked, causing poor ventilation in the air duct 100. This facilitates timely detection of factors that hinder ventilation in the air duct 100, helps prevent energy waste on the ineffective operation of the reversible fan 200, and promotes energy-saving and low-carbon operation of the ventilation equipment.

[0023] like Figure 1 and Figure 2As shown, in this embodiment, a silencer 130 is connected and fixed to one end of the filter box 120 away from the ventilation duct 110. A sound-absorbing material is sleeved and fixed to the inner side of the silencer 130. A protective net is installed and fixed to the opening of the silencer 130 to prevent debris from entering the ventilation duct 100. The silencer 130 is a common structure on the existing ventilation duct 100. The specific sound-absorbing working principle of the silencer 130 will not be described in detail.

[0024] In this embodiment, a connecting ear is welded and fixed to the top of the filter box 120. The connecting ear is used to suspend and install the two air ducts 100, and also facilitates the hoisting of the air ducts 100 during the installation process.

[0025] like Figure 2 and Figure 5 As shown, in this embodiment, the reversible fan 200 includes a motor 210 fixedly connected to the ventilation duct 110. The output end of the motor 210 is fixed with a fan blade 220, and the bottom of the motor 210 is fixed with a T-shaped support 230. The support 230 is fixedly connected to the inner wall of the ventilation duct 110. During ventilation, the output end of the motor 210 rotates with the fan blade 220 to draw outside air into the ventilation duct 100, and then discharges it into the tunnel from the other end of the ventilation duct 100. Conversely, if the output end of the motor 210 rotates in the opposite direction with the fan blade 220, it can draw the polluted air in the tunnel and discharge it to the outside.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, a motor 3121 is fixed to the bottom of each of the two filter boxes 120. The output end of the motor 311 is fixedly connected to the corresponding roller 310. The outer side of the roller 310 is hollowed out to facilitate the smooth flow of air into the air duct 100. The output end of the motor 311 drives one roller 310 to rotate, and the other roller 310, which is connected to the roller 310 through the filter belt 320, rotates synchronously, so that the filter belt 320 can be driven inside the filter box 120. As needed, the mesh 321 area on the filter belt 320 can be arranged inside the filter box 120 to achieve the effect of filtering impurities in the air. Alternatively, the through hole 322 area on the filter belt 320 can be arranged inside the filter box 120 to prevent the air duct 100 from being blocked due to the filter belt 320 being clogged.

[0027] like Figure 4 As shown, in this embodiment, the filter belt 320 is provided with a mesh area 321, which is equivalent to a filter in the prior art and can filter dust and impurities in the air. The filter belt 320 is provided with through holes 322, which do not have a filtering function. When the through hole 322 area moves into the air duct 100, the opening of the air duct 100 is equivalent to being directly connected to the outside.

[0028] like Figure 5 - Figure 7 As shown, in this embodiment, the slide rail 510 is fixedly connected to the U-shaped plate 410, the top of the movable seat 520 is rotatably connected to the support shaft 530, the support shaft 530 is fixedly connected to the air volume meter 540, the outer side of the support shaft 530 is sleeved and fixedly fitted with a gear 531, the transmission frame 550 and the second motor 570 are both fixedly connected to the U-shaped plate 410, the middle part of the transmission frame 550 is embedded and fixedly fitted with a rack 551 that meshes with the gear 531, the output end of the second motor 570 is fixedly fitted with a drive wheel 580, the outer side of the drive wheel 580 is rotatably connected to a transmission column 560, and the transmission column 560 is inserted and fixedly fitted to the movable seat 520.

[0029] In this embodiment, the anemometer 540 is initially arranged parallel to the U-shaped plate 410. At this time, the outer side of the gear 531 meshes with the rack 551. When the moving seat 520 drives the support shaft 530 to move the anemometer 540 towards any end of the slide rail 510 and close to the corresponding air exchanger 110, the gear 531 will roll on the rack 551. The rack 551 stops rotating after the gear 531 rotates 90 degrees, that is, on the support shaft... After rotating 90 degrees with the air volume meter 540, the 530 stops rotating, allowing the air volume meter 540, which is arranged parallel to the U-shaped plate 410, to be inserted into the ventilation cylinder 110 in an orientation perpendicular to the U-shaped plate 410 for detection. When the moving base 520 returns to its initial position with the air volume meter 540 on the support shaft 530, the gear 531 will mesh in the opposite direction on the rack 551, thereby readjusting the air volume meter 540 back to be arranged parallel to the U-shaped plate 410 for later use. In this embodiment, since gear 531 is located in the middle of rack 551 in the initial state, when the moving seat 520 moves with support shaft 530 to different positions of the air duct 100, gear 531 can first rotate support shaft 530 by 90 degrees, so that air volume meter 540 rotates to align with air duct 100, and then enters air duct 100. The distance between the two air ducts 110 meets the rotation space requirements of air volume meter 540, so that air volume meter 540 can enter the detection hole 111 on air duct 110 after the position is adjusted. The size of detection hole 111 is slightly larger than the size of air volume meter 540, which helps air volume meter 540 pass through detection hole 111.

[0030] like Figure 6 and Figure 7As shown, in this embodiment, a drive shaft 581 is fixed at an eccentric position on the drive wheel 580, and a long slot 561 is provided in the middle of the drive column 560. The drive column 560 is L-shaped, and its bottom is inserted and fixed on the movable seat 520. When the drive wheel 580 rotates, the drive shaft 581 on the drive wheel 580 will cause the drive column 560 to move the movable seat 520 in translation through the limiting effect of the long slot 561. When the drive wheel 580 moves the drive shaft 581 to one end of the drive wheel 580, as the drive wheel 580 continues to rotate, the drive shaft 581 will drive the drive column 560 to drive the movable seat 520 to move in the opposite direction. This enables the drive wheel 580 to move back and forth on the slide rail 510 with the movable seat 520. The movable seat 520 moves in different directions, which helps the air volume meter 540 to be inserted into different air exchangers 110.

[0031] like Figure 2 and Figure 5 As shown, in this embodiment, a partition 411 is fixed on the top surface of the C-shaped plate 410, and a cover plate 420 is detachably installed and fixed on the opening of the C-shaped plate 410. The filter belt 320 is arranged in the space between the C-shaped plate 410 and the partition 411. The cover plate 420 can be opened when maintaining the ventilation equipment.

[0032] Example 2, based on Example 1, is to clean the dust and impurities intercepted on the filter belt 320.

[0033] like Figure 5 and Figure 8 As shown, in this embodiment, cleaning components 600 are provided at both ends of the C-shaped plate 410. The cleaning component 600 includes a pipe 610 that is connected to the output end of the second motor 570 on the detection mechanism 500 via a one-way bearing. This allows the pipe 610 to rotate only when the second motor 570 rotates in a specific direction. A connecting shaft 620 is installed at one end of the pipe 610 via a spline snap-fit, allowing the connecting shaft 620 to slide along the pipe 610 and rotate with it. A circular plate 630 is fixed at one end of the connecting shaft 620, and a brush disc 640 is sleeved and fixed on the outer side of the circular plate 630. The brush disc 640 can clean the filter belt 320.

[0034] In this embodiment, when the clogged area of ​​the filter belt 320 is transmitted to the front of the brush disc 640, the output end of the second motor 570 can be rotated in the opposite direction to drive the pipe 610 to rotate using a one-way bearing. The second motor 570 is a dual-axis motor. The pipe 610 rotates with the connecting shaft 620, causing the circular plate 630 to rotate with the brush disc 640, thereby cleaning the mesh area 321 of the filter belt 320.

[0035] In this embodiment, during maintenance, the cover plate 420 can be opened, and the mesh area 321 on the filter belt 320 can be moved to the position facing the brush disc 640 on the windward side that intercepts dust. The user can pull the connecting shaft 620 out of the tube 610 and extend it so that the brush disc 640 contacts the windward side of the filter belt 320, which facilitates cleaning the filter belt 320 from different sides. When cleaning with the cover plate 420 open, cleaning fluid can also be used as needed. The specific cleaning operation can be adjusted according to actual needs.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
