Description

Technical Field

[0001] This application relates to the field of tunnel ventilation technology, and in particular to an intelligent ventilation device. Background Technology

[0002] Intelligent ventilation equipment for tunnels is used to manage air quality and reduce dust concentration within tunnels. In tunnels, factors such as vehicle exhaust and road dust can increase the concentration of dust in the air. High concentrations of dust not only reduce visibility and increase driving risks, but can also negatively impact the health of drivers and passengers. Therefore, ventilation within tunnels is essential to ensure driving safety and public health.

[0003] Among the related technologies, there is a design for an intelligent ventilation device for tunnels, which includes a ventilation duct connecting the inside and outside of the tunnel and a box connected to the ventilation duct. The box is equipped with a fan and a filter. The operation of the fan causes the air inside the tunnel to flow along the ventilation duct, realizing the air exchange between the inside and outside of the tunnel. The filter intercepts dust in the air to reduce the dust content entering the tunnel.

[0004] In the process of developing this application, it was found that the technology has at least the following problems: after prolonged use, a large amount of dust will gradually accumulate on the surface of the filter, greatly increasing the ventilation resistance, reducing the filtration effect, and deteriorating the air quality inside the tunnel. Utility Model Content

[0005] In order to facilitate cleaning of the filter structure, reduce ventilation resistance, and ensure the filtration effect of the filter, this application provides an intelligent ventilation device.

[0006] The intelligent ventilation device provided in this application adopts the following technical solution:

[0007] An intelligent ventilation device includes a housing connected to a ventilation duct. A set of vertically extending slits are formed on both sides of the housing. A set of supports extending to both sides are symmetrically and fixedly mounted on the housing. A winding roller is vertically and rotatably mounted on each support. A filter belt is positioned between two winding rollers. One end of the filter belt is fixed and wound around one of the winding rollers. The middle portion of the filter belt passes through the slits into the interior of the housing. The other end of the filter belt is fixed and wound around the other winding roller. A traction power assembly is mounted on the supports to drive the winding rollers to rotate and to fix them in place. A brush roller is vertically and rotatably mounted on the supports, abutting against the surface of the filter belt. A cleaning power assembly is mounted on the supports to drive the brush rollers to rotate.

[0008] By adopting the above technical solution, during ventilation, the portion of the filter belt inside the housing filters dust. After the ventilation equipment has been used for a period of time, dust accumulates on the portion of the filter belt inside the housing. The traction power component drives the winding rollers to rotate; one winding roller releases the filter belt, while the other winding roller retracts it, causing the dust-covered portion of the filter belt to move out of the housing, while the dust-free portion enters, ensuring continuous and efficient ventilation filtration. During this process, a brush roller against the surface of the filter belt rotates under the drive of the cleaning power component, cleaning the dust-covered portion of the filter belt that has moved out of the housing. This facilitates cleaning of the filter structure, reduces ventilation resistance, and ensures the filtration effect of the filter. The entire filter belt replacement and cleaning process eliminates the need for tedious manual disassembly, cleaning, and reinstallation of the filter, improving the intelligence level of the ventilation equipment.

[0009] Preferably, two brush rollers are rotatably arranged on each bracket, with one brush roller on the same bracket abutting one side surface of the filter belt and the other brush roller abutting the other side surface of the filter belt.

[0010] By adopting the above technical solution, when cleaning the filter belt, two brush rollers act simultaneously from both sides of the filter belt. Compared with only one brush roller, this can more comprehensively and thoroughly clean the dust on the surface of the filter belt.

[0011] Preferably, the cleaning power assembly includes a first motor, a drive gear, and a driven gear. Among the two brush rollers located on the same bracket, the drive gear is coaxially fixed with one of the brush rollers, and the driven gear is coaxially fixed with the other brush roller. The drive gear and the driven gear mesh with each other. The first motor is fixed on the bracket, and the drive shaft of the first motor is coaxially fixed with the drive gear.

[0012] By adopting the above technical solution, the first motor is started, and the first motor drive shaft drives the active gear to rotate. Since the active gear and the driven gear mesh with each other, the first motor can synchronously drive the driven gear to rotate in the opposite direction, thereby enabling the two brush rollers fixed on the same axis to rotate in the opposite direction, and simultaneously and efficiently cleaning dust from both sides of the filter belt.

[0013] Preferably, the traction power assembly includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley and the driven pulley have the same diameter. The driving pulley is coaxially fixed to a winding roller on one of the supports, and the driven pulley is coaxially fixed to a winding roller on another support. The transmission belt is driven between the two driving pulleys and the driven pulley. One end of the transmission belt is sleeved on the driving pulley, and the other end of the transmission belt is sleeved on the driven pulley.

[0014] By adopting the above technical solution, when the filter part of the filter belt needs to be replaced, the drive pulley rotates, and the driven pulley rotates synchronously by the friction of the transmission belt. Since the diameters of the drive pulley and the driven pulley are equal, it can be ensured that the two winding rollers rotate at the same linear speed, so that the filter belt can be smoothly wound or released.

[0015] Preferably, the traction power assembly further includes a second motor, which is fixedly mounted on the bracket. The drive shaft of the second motor is coaxially fixed with the drive pulley, and the second motor is a servo motor.

[0016] By adopting the above technical solution, the servo motor has high-precision control characteristics and can accurately control the rotation angle of the drive pulley, thereby changing the movement range of the filter belt.

[0017] Preferably, a fixed frame is fixedly installed inside the box, and a sliding frame is slidably installed inside the box. The filter belt is located between the fixed frame and the sliding frame inside the box. A clamping component is provided on the box, which is used to drive the sliding frame closer to the fixed frame and fix the sliding frame.

[0018] By adopting the above technical solution, before the ventilation equipment is put into operation, the sliding frame is brought closer to the fixed frame by the clamping component, and the filter belt is tightly clamped between the two. This effectively prevents the filter belt from loosening or shifting due to airflow impact during ventilation, ensuring that the filter belt is always in the optimal filtration position, improving the filtration effect, reducing the noise caused by the shaking of the filter belt, and optimizing the equipment operating environment.

[0019] Preferably, the clamping assembly includes a cam, a rotating shaft, and a third motor. The rotating shaft is vertical and rotatably mounted inside the housing. The third motor is fixedly mounted on the housing. The drive shaft of the third motor passes through the top of the housing and is fixedly connected to the rotating shaft. The cam abuts against the side of the sliding frame away from the fixed frame.

[0020] By adopting the above technical solution, the third motor is started, the drive shaft drives the rotating shaft to rotate, and then the cam rotates accordingly. Utilizing the contour characteristics of the cam, when the convex part of the cam gradually turns towards the sliding frame, it will push the sliding frame closer to the fixed frame, thereby achieving the pressing of the filter belt.

[0021] Preferably, a collection chamber is fixedly installed on the outside of the box, the brush roller is located inside the collection chamber, and the collection chamber is fixedly and connected to a water injection pipe for injecting water into the collection chamber and a drain pipe for draining water out of the collection chamber.

[0022] By adopting the above technical solution, during the process of the brush roller sweeping the dust off the filter screen, the dust will fall into the collection chamber. Water is injected into the collection chamber through the water injection pipe, which can mix the dust with the water to form a slurry, thus avoiding dust flying and causing secondary pollution. The drain pipe facilitates the regular discharge of the collected wastewater, keeping the collection chamber clean and ensuring that the entire cleaning process is environmentally friendly and efficient, further maintaining the environmental hygiene around the ventilation equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a housing, slots, brackets, winding rollers, filter belts, traction power components, brush rollers, and cleaning power components, when dust accumulation affects the filtration effect, the traction power components drive the winding rollers to switch the working position of the filter belt, and the brush rollers are driven by the cleaning power components to clean the dirty parts, thereby reducing ventilation resistance;

[0025] 2. By setting up an active pulley, a driven pulley, a transmission belt, and a second motor, the winding rollers on both sides of the housing rotate synchronously and smoothly, so that one winding roller releases the filter belt and the other winding roller winds the filter belt, achieving coordinated action and minimizing the tension on the filter belt;

[0026] 3. By setting up a fixed frame, a sliding frame, a clamping component, a cam, a rotating shaft, and a third motor, the cam rotates under the drive of the third motor, pushing the sliding frame closer to the fixed frame to fix the filter belt. This helps the filter belt resist the impact of airflow during ventilation and ensures the stability of the filter belt. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses an intelligent ventilation device. (Refer to...) Figures 1 to 3 The device includes a housing 1 connected to a ventilation duct, and a fan is installed inside the housing 1. A set of vertically extending slots 11 are formed on both sides of the housing 1. A set of symmetrically extending supports 2 are fixedly installed on the housing 1. A winding roller 21 is vertically and rotatably mounted on each support 2. A filter belt 211 is positioned between two winding rollers 21. One end of the filter belt 211 is fixed and wound around one of the winding rollers 21, the middle of the filter belt 211 passes through the slots 11 into the interior of the housing 1, and the other end of the filter belt 211 is fixed and wound around the other winding roller 21. A traction power assembly 22 is installed on the support 2, which drives the winding rollers 21 to rotate and fix them in place. In this embodiment, a set of reversing rollers is also vertically and rotatably arranged on the bracket 2. The reversing rollers are located at the slit hole 11. The filter belt 211 is parallel to the side wall of the box 1 after being reversed by the reversing rollers outside the box 1. The filter belt 211 is a strip filter made of polyester fiber material.

[0033] Reference Figure 2 and Figure 3 During ventilation, the fan starts, and the filter belt 211 inside the housing 1 filters dust. After the ventilation equipment has been used for a period of time, the filter belt 211 inside the housing 1 becomes contaminated with dust. The traction power component 22 drives one winding roller 21 to release the filter belt 211, while the other winding roller 21 retracts the filter belt 211, causing the dust-contaminated part of the filter belt 211 to move out of the housing 1, while the dust-free part enters the housing 1, ensuring the ventilation and filtration effect.

[0034] Reference Figure 1 and Figure 2 A brush roller 23 is vertically and rotatably mounted on the support 2, and the brush roller 23 abuts against the surface of the filter belt 211. A cleaning power assembly 24 for driving the brush roller 23 to rotate is provided on the support 2. A collection chamber 3 is fixedly mounted on the outside of the housing 1, and the brush roller 23 is located inside the collection chamber 3. The collection chamber 3 is fixedly connected to a water injection pipe 31 for injecting water into the collection chamber 3 and a drain pipe 32 for draining water out of the collection chamber 3.

[0035] Reference Figure 1 and Figure 2In this embodiment, the support 2 includes an upper frame fixed to the top of the side wall of the housing 1 and a lower frame fixed to the bottom of the side wall of the housing 1. The lower frame and the upper frame together support the winding roller 21, brush roller 23, and reversing roller located on the same side of the housing 1. Two brush rollers 23 are rotatably arranged on each support 2. One brush roller 23 located on the same support 2 abuts against one side surface of the filter belt 211, and the other brush roller 23 abuts against the other side surface of the filter belt 211. The collection chamber 3 is a closed box provided on both sides and the bottom of the housing 1. Valves are provided on the water inlet pipe 31 and the drain pipe 32. The valves can be solenoid valves.

[0036] Reference Figure 1 and Figure 2 As the filter belt 211 moves, the brush roller 23 rotates under the drive of the cleaning power unit 24, cleaning the dusty parts of the filter belt 211 that have moved out of the housing 1. This facilitates cleaning of the dusty parts of the filter belt 211, allowing the filter belt 211 to be reused. The swept-off dust is blocked by the collection chamber 3, preventing direct air pollution. Furthermore, the dust falls off after being brushed off and comes into contact with the water injected into the collection chamber 3 through the water injection pipe 31, preventing it from flying around and keeping the collection chamber 3 clean.

[0037] To facilitate the simultaneous driving of the two brush rollers 23 to clean both sides of the filter belt, refer to Figure 2 The cleaning power assembly 24 includes a first motor 241, a drive gear 242, and a driven gear 243. Of the two brush rollers 23 located on the same support 2, the drive gear 242 is coaxially fixed to one brush roller 23, and the driven gear 243 is coaxially fixed to the other brush roller 23. The drive gear 242 and the driven gear 243 mesh with each other. The first motor 241 is fixed to the support 2, and its drive shaft is coaxially fixed to the drive gear 242. The drive shaft of the first motor 241 drives the drive gear 242 to rotate. The drive gear 242 meshes with the driven gear 243 and drives the driven gear 243 to rotate in the opposite direction, thereby causing both brush rollers 23 to rotate simultaneously. The brush rollers 23 simultaneously sweep dust from both sides of the filter belt 211.

[0038] To facilitate the driving of one winding roller 21 to release the filter belt 211 and the other winding roller 21 to retract the filter belt 211, refer to... Figure 2The traction power assembly 22 includes a driving pulley 221, a driven pulley 222, a transmission belt 223, and a second motor 224. The driving pulley 221 and the driven pulley 222 have the same diameter. The driving pulley 221 is coaxially fixed to a winding roller 21 on one of the supports 2, and the driven pulley 222 is coaxially fixed to a winding roller 21 on the other support 2. The transmission belt 223 is driven between the two driving pulleys 221 and the driven pulley 222, with one end of the transmission belt 223 sleeved on the driving pulley 221 and the other end sleeved on the driven pulley 222. The second motor 224 is fixedly mounted on the support 2, and its drive shaft is coaxially fixed to the driving pulley 221. The second motor 224 is a servo motor. When the filter section of the filter belt 211 needs to be replaced, the drive pulley 221 rotates, which drives the driven pulley 222 to rotate synchronously by the transmission belt 223, thereby driving one winding roller 21 to release the filter belt 211 and the other winding roller 21 to tighten the filter belt 211.

[0039] To ensure the stability of the filter belt 211 within the housing 1, refer to... Figure 1 and Figure 3 A fixed frame 12 is fixedly installed inside the housing 1, and a sliding frame 13 is slidably installed inside the housing 1. The filter belt 211 is located inside the housing 1 between the fixed frame 12 and the sliding frame 13. In this embodiment, rubber pads are provided on the sides of the fixed frame 12 and the sliding frame 13 that are close to each other. A pressing assembly 14 is provided on the housing 1. The pressing assembly 14 is used to drive the sliding frame 13 close to the fixed frame 12 and fix the sliding frame 13. The pressing assembly 14 includes a cam 141, a rotating shaft 142, and a third motor 143. The rotating shaft 142 is vertically and rotatably installed inside the housing 1. The third motor 143 is fixedly installed on the housing 1, and the drive shaft of the third motor 143 passes through the top of the housing 1 and is fixedly connected to the rotating shaft 142. The cam 141 abuts against the side of the sliding frame 13 that is away from the fixed frame 12. In this embodiment, two rotating shafts 142 are arranged side by side inside the housing 1. One cam 141 is fixedly installed at the top and bottom of each rotating shaft 142. Each rotating shaft 142 is driven by a third motor 143. The four cams 141 simultaneously push the sliding frame 13 to slide, which helps improve the sliding stability of the sliding frame 13. This embodiment also includes a return spring that drives the sliding frame 13 away from the fixed frame 12.

[0040] Reference Figure 1 and Figure 3 Before the ventilation equipment is operated, the third motor 143 is started. The third motor 143 drives the rotating shaft 142 to rotate, which in turn causes the cam 141 to rotate. The protruding part of the cam 141 pushes the sliding frame 13 closer to the fixed frame 12, thereby pressing the filter belt 211. The filter belt 211 is tightly clamped between the two, effectively preventing the filter belt 211 from loosening or shifting due to airflow impact during ventilation.

[0041] The implementation principle of an intelligent ventilation device according to an embodiment of this application is as follows: When the ventilation device is running, the fan starts, and the air in the ventilation duct flows through the housing 1. The part of the filter belt 211 located inside the housing 1 filters the dust in the air. As the usage time increases, the part of the filter belt 211 located inside the housing 1 will be covered with dust, affecting the ventilation filtration effect. At this time, the third motor 143 starts, and the sliding frame 13 moves away from the fixed frame 12 under the action of the return spring, thereby releasing the filter belt 211. Then the second motor 224 starts, and through the cooperation of the driving pulley 221, the driven pulley 222 and the transmission belt 223, one winding roller 21 is driven to release the filter belt 211, while the other winding roller 21 pulls back the filter belt 211, moving the dusty part of the filter belt 211 out of the housing 1, and the dust-free part moving into the housing 1, so as to continue to ensure the ventilation filtration effect. Finally, the third motor 143 starts again, and under the action of the sliding frame 13 cam 141, it approaches the fixed frame 12 and clamps the filter belt 211 to prevent the filter belt 211 from loosening or shifting due to airflow impact during ventilation.

[0042] As the filter belt 211 moves, the first motor 241 on the side where the filter belt 211 has moved out starts. The first motor 241 drives the drive gear 242 to rotate, and through meshing with the driven gear 243, drives the two brush rollers 23 to rotate in opposite directions simultaneously, cleaning the dusty part of the filter belt 211 that has moved out of the housing 1. The swept-off dust is blocked by the collection chamber 3 and falls off under gravity, coming into contact with the water injected into the collection chamber 3 through the water injection pipe 31, preventing the dust from flying around. The water in the collection chamber 3 is discharged through the drain pipe 32.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
