Description

Technical Field

[0001] This utility model belongs to the field of platform screen door technology, and in particular relates to a platform screen door structure with adjustable ventilation openings. Background Technology

[0002] According to the published patent CN204371054U, an adjustable ventilated platform door for rail transit is provided. Ventilation openings are provided above and / or below the platform door. An openable and closable air valve is installed on the side of the ventilation opening near the track. Ventilation louvers are installed on the side of the ventilation opening near the platform. The cross-section of the louver blades is arc-shaped. Because the structural strength and stability of the arc-shaped blades are much higher than ordinary plate blades, the blades on the platform door will not vibrate or whistle while the rail transit vehicle generates a large piston-like airflow to ventilate the platform. Furthermore, the arc-shaped blades can help prevent airborne dust from entering the platform area, keeping the platform clean. However, the following shortcomings still exist: The aforementioned equipment can prevent air dust from entering the platform area and keep the platform clean. However, the platform door often needs to be ventilated to improve the comfort of the platform. However, due to different external temperature and other factors, the air volume needs to be adjusted to a certain extent. The aforementioned equipment is not convenient to adjust during use, which reduces the applicability of the device. Therefore, we propose a platform door structure with adjustable ventilation openings. Utility Model Content

[0003] The purpose of this utility model is to provide a platform door structure with adjustable ventilation openings. Through the adjustment mechanism and cleaning mechanism, it solves the problem that the above-mentioned equipment can prevent air dust from entering the platform area and keep the platform clean. However, the platform door often needs to be blown to improve the comfort of the platform. However, due to different external temperature and other factors, its air volume needs to be adjusted to a certain extent. The above-mentioned equipment is not convenient to adjust during use, which reduces the applicability of the device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a platform door structure with adjustable ventilation openings, including a platform door body, a ventilation pipe fixedly connected to the outer wall of the platform door body, and an adjustment mechanism provided on the inner wall of the platform door body; The adjustment mechanism includes several fixed frames, with several limiting shafts rotatably connected to the inner walls of the fixed frames. Each limiting shaft has a baffle fixedly connected to its outer wall, and a connecting rod rotatably connected to the inner wall of each baffle. A first motor is fixedly connected to the inner wall of the platform door body near the connecting rod, and several worm gears are rotatably connected to the inner wall of the platform door body near the first motor. A connecting shaft is fixedly connected to the outer wall of the lower limiting shaft, and a worm wheel is fixedly connected to the outer wall of the connecting shaft. Pulleys are fixedly connected to the outer walls of each worm gear, and a belt is driven through the outer walls of the pulleys. A cleaning mechanism is provided on the inner wall of the platform door body.

[0005] Furthermore, the outer walls of several of the fixed frames are fixedly connected to the inner wall of the platform door body, the outer wall of the worm gear on the right side is fixedly connected to the bottom output end of the first motor, and the outer wall of the worm wheel meshes with the outer wall of the worm gear.

[0006] Furthermore, the cleaning mechanism includes a dustproof plate, the outer wall of which is fixedly connected to the inner wall of the platform door body.

[0007] Furthermore, a collection plate is slidably connected to the inner wall of the platform door body near the dustproof plate, and a connecting plate is fixedly connected to the inner wall of the platform door body near the first motor.

[0008] Furthermore, a second motor is fixedly connected to the top outer wall of the connecting plate, and a drive shaft is fixedly connected to the bottom output end of the second motor via a coupling.

[0009] Furthermore, a number of slide rails are fixedly connected to the inner wall of the platform door body near the collection plate, and screws are rotatably connected to the inner walls of the slide rails.

[0010] Furthermore, a brush plate is threadedly connected to the outer wall of the screw, and gears are fixedly connected to both the outer wall of the screw on the right side and the outer wall of the drive shaft.

[0011] Furthermore, pulleys are fixedly connected to the outer walls of several screws, and belts are driven to the outer walls of the pulleys.

[0012] This utility model has the following beneficial effects: 1. This utility model, by setting a baffle on the limiting shaft, allows the first motor to be started when the ventilation volume needs to be controlled. The rotation of the first motor drives the right worm gear to rotate, causing the worm wheel on the right connecting shaft to rotate. Simultaneously, the rotation of the right worm gear drives the right pulley to rotate, causing the belt to rotate, which in turn drives the left pulley to rotate, causing the left worm gear to rotate, and thus the right connecting shaft to rotate. The rotation of the connecting shaft drives the lower limiting shaft to rotate, allowing the user to freely control the ventilation volume of the device according to the actual usage situation. This ensures that the air pressure at the platform is in a balanced state before and after the train enters the station, reducing the vibration of the train doors. Moreover, the adjustment method of the device is simple and convenient.

[0013] 2. This utility model incorporates a brush plate within the slide rail. During operation, the dustproof plate filters the blown air, and the filtered dust falls into the collection plate. When cleaning the dustproof plate is required, the second motor is activated. Due to the meshing of multiple gears, the rotation of the second motor drives the transmission shaft, causing the gears on the transmission shaft to rotate, which in turn drives the gears on the right-side screw to rotate. This achieves the goal of effectively removing dust from the air blown by the device through the dustproof plate. Simultaneously, the device can clean the dustproof plate to a certain extent, preventing the filter holes on the dustproof plate from becoming clogged with dust and other impurities over prolonged use, thus reducing the dust removal efficiency of the device.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 As shown, this utility model is a platform door structure with adjustable ventilation opening, including a platform door body 1, a ventilation pipe 101 fixedly connected to the outer wall of the platform door body 1, and an adjustment mechanism 2 provided on the inner wall of the platform door body 1. The adjusting mechanism 2 includes several fixed frames 201. These fixed frames 201 can fix the position of the limiting shaft 202, ensuring it can only rotate within the fixed frame 201 and preventing it from falling. Several limiting shafts 202 are rotatably connected to the inner wall of the fixed frame 201. Each limiting shaft 202 has a baffle 203 fixedly connected to its outer wall. A connecting rod 204 is rotatably connected to the inner wall of the baffle 203. A first motor 205 is fixedly connected to the inner wall of the platform door main body 1 near the connecting rod 204. When the first motor 205 is started, its rotation drives the worm gear 206 on the right side to rotate, which in turn drives the worm wheel 207 on the right side to rotate. Several worm gears 206 are rotatably connected to the inner wall of one end of 205. A connecting shaft 210 is fixedly connected to the outer wall of the lower limiting shaft 202. The connecting shaft 210 can fix the position of the worm wheel 207 to prevent the worm wheel 207 from falling off and to prevent the worm wheel 207 from disengaging from the meshing state with the worm gear 206. The worm wheel 207 is fixedly connected to the outer wall of the connecting shaft 210. Pulleys 208 are fixedly connected to the outer walls of several worm gears 206. A belt 209 is driven to the outer wall of the pulleys 208. A cleaning mechanism 3 is provided on the inner wall of the platform door body 1. The pulleys 208 can drive the belt 209 and prevent the belt 209 from being misaligned or falling off during the transmission process.

[0020] The outer walls of several fixed brackets 201 are fixedly connected to the inner wall of the platform door body 1. The outer wall of the worm gear 206 on the right side is fixedly connected to the bottom output end of the first motor 205. The outer wall of the worm wheel 207 meshes with the outer wall of the worm gear 206. Through the worm wheel 207, the worm gear 206 can be driven to rotate. When the worm wheel 207 rotates, it can drive the worm gear 206 to rotate. The cleaning mechanism 3 includes a dustproof plate 301. The outer wall of the dustproof plate 301 is fixedly connected to the inner wall of the platform door body 1. The platform door body 1 is close to the dustproof plate 301. A collection plate 302 is slidably connected to the inner wall of one end of the plate 301. The collection plate 302 can collect the dust and other impurities that have been cleaned, making it convenient for users to remove and empty them later. A connecting plate 303 is fixedly connected to the inner wall of the platform door body 1 near the first motor 205. A second motor 304 is fixedly connected to the top outer wall of the connecting plate 303. The connecting plate 303 can support and fix the second motor 304, preventing the second motor 304 from shaking violently during operation and affecting the subsequent normal transmission.

[0021] The bottom output end of the second motor 304 is fixedly connected to a drive shaft 305 via a coupling. Several slide rails 306 are fixedly connected to the inner wall of the platform gate body 1 near the collection plate 302. Each slide rail 306 has a screw 307 rotatably connected to its inner wall. The slide rails 306 limit the movement trajectory of the brush plate 308, allowing it to move up and down along the straight line of the slide rail 306. The outer wall of the screw 307 is threadedly connected to the brush plate 308. Gears 309 are fixedly connected to the outer wall of the right-side screw 307 and the outer wall of the drive shaft 305. Each screw 307 has a pulley 310 fixedly connected to its outer wall. A belt 311 is driven to the outer wall of the pulley 310. The pulley 310 can drive the belt 311. When the right-side pulley 310 rotates, it can drive the belt 311 to rotate.

[0022] One specific application of this embodiment is: When staff need to use the equipment, air conditioning air can be injected into the platform door body 1 through the ventilation pipe 101 and blown out. When ventilation volume needs to be controlled, the first motor 205 is started. The rotation of the first motor 205 drives the right worm gear 206 to rotate, causing the worm wheel 207 on the right connecting shaft 210 to rotate. At the same time, the rotation of the right worm gear 206 drives the right pulley 208 to rotate, causing the belt 209 to rotate, which in turn drives the left pulley 208 to rotate, causing the left worm gear 206 to rotate, which in turn causes the right connecting shaft 210 to rotate. The rotation of the connecting shaft 210 drives the lower limit shaft 202 to rotate, which in turn drives the lower baffle 203 to rotate, causing the connecting rod 204 to move. This, in turn, simultaneously drives the upper baffles 203 to move the platform door body 1, causing the upper limit shafts 202 to rotate simultaneously within the fixed frame 201. By controlling the baffles 202... Position 3 allows for adjustment of the device's ventilation volume. The dustproof plate 301 filters the blown air, and the filtered dust falls into the collection plate 302. When the dustproof plate 301 needs cleaning, the second motor 304 can be started. Due to the meshing of multiple gears 309, the rotation of the second motor 304 drives the transmission shaft 305 to rotate, causing the gears 309 on the transmission shaft 305 to rotate, which in turn causes the gears 309 on the right screw 307 to rotate, which in turn drives the right screw 307 to rotate. The rotation of the right screw 307 causes the right pulley 310 to rotate, which in turn causes the belt 311 to rotate, which in turn causes the left pulley 310 to rotate. The rotation of the left pulley 310 causes the left screw 307 to rotate, which in turn causes the brush plate 308 to move within the slide rail 306, scraping off the dust adhering to the outer wall of the dustproof plate 301.
