Description

Technical Field

[0001] The present invention relates to the technical field of guiding devices, and in particular to a rail transit passenger flow guiding device. Background Art

[0002] In rail transit, guiding devices are often installed to separate pedestrian traffic flow and facilitate travel in different directions. However, current guiding devices often accumulate dust on the screens over time, resulting in poor guidance effectiveness and misjudgment of pedestrians, making them less practical.

[0003] To solve the above problems, a rail transit passenger flow guiding device has appeared on the market, including a support, a guide screen, a water tank, and a hose; the guide screen is fixedly connected to the support; the water tank is fixedly connected to the support; the hose is connected to the water tank; when the device is in use, if a lot of dust accumulates on the guide screen, the worker can pull the hose, and then the hose can flush the dust on the guide screen, thereby reducing the amount of dust accumulation and improving the cleanliness of the guide screen, thus ensuring the quality of guidance for the workers.

[0004] The above device has the following problems during actual use: when cleaning the guide screen, the device still requires workers to pull the hose to clean the dust accumulated on the guide screen. However, it is difficult for workers to control the cleaning angle of the hose manually, which causes water to splash onto the guide screen, thereby affecting the workers and causing inconvenience. On the other hand, the cleaning process is relatively cumbersome, which brings unnecessary trouble to the workers' work. Summary of the Invention

[0005] The present invention provides a rail transit passenger flow guiding device to solve the problem that when the existing guiding device cleans the guiding screen, the manual cleaning effect is poor.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a rail transit passenger flow guiding device, including a base and a display screen, which is fixedly connected to the base and also includes a cleaning mechanism; the cleaning mechanism includes a box body with an opening at the bottom and cleaning components symmetrically arranged on both sides of the display screen along the length direction of the display screen; the cleaning component includes a water tank, a side pipe, and a cleaning part arranged in the side pipe; the water tank is fixedly connected to the inner wall of the box body; the side pipe is connected to the water tank, and the side pipe is fixedly connected to the display screen; the cleaning part includes a side block, a long plate, a plurality of cleaning units equidistantly arranged along the length direction of the long plate, and a driving unit for driving the side block to reciprocate along the length direction of the side pipe; the side block is slidably connected to the side pipe; the long plate is fixedly connected to the side block; the cleaning unit includes a moving tube, a through hole opened on the long plate, and a sliding hole opened on the side tube; the moving tube is fixedly connected to the through hole, and the moving tube can slide in and out of the sliding hole.

[0007] The principles and advantages of this solution are: When dust accumulates on the display screen, clean water is directed into the side pipes via a water tank and ejected through several sliding holes. Once ejected, the clean water washes away the dust on the display screen, reducing dust accumulation and improving its cleanliness. This mechanical operation replaces manual labor, saving workers unnecessary effort and enhancing cleaning effectiveness and efficiency. It also prevents water splashing, improving the comfort level during cleaning and enhancing the practicality of the device.

[0008] As the clean water is sprayed through the sliding hole, the movable tube reciprocates along the length of the sliding hole. This movement adjusts the initial spray position, allowing the water to reach a greater distance and more comprehensively clean the display screen. This movement allows the water to more thoroughly and efficiently clean different locations on the display screen as the initial spray distance varies, further improving the water's cleanliness.

[0009] Furthermore, it also includes a boosting part arranged in the side tube; the boosting part includes a first screw, a first guide rod, a first nut seat, a vertical plate, a plurality of boosting blocks equidistantly arranged along the length direction of the vertical plate, and a power unit for driving the first screw to rotate; the first screw is rotatably connected to the side tube; the first guide rod is fixed to the side tube; the first nut seat is threadedly connected to the first screw, and the first nut seat is slidably connected to the first guide rod; the vertical plate is fixed to the first nut seat; the boosting block is fixed to the vertical plate; the moving tube is an elastic tube, and the moving tube is located on the movement trajectory of the boosting block.

[0010] During the movement of the movable tube, the first screw drives the first nut holder to reciprocate along the length of the first guide rod, thereby enabling the first nut holder to drive the pressure-boosting block toward the location of the elastic tube. During the movement of the pressure-boosting block, the elastic tube deforms under the action of the pressure-boosting block, thereby adjusting the diameter of the elastic tube. This allows the clean water sprayed through the movable tube to reach a greater distance and a wider range, thereby ensuring a more effective cleaning effect on the display screen.

[0011] As the boosting block approaches the position of the elastic tube, the elastic tube can change its position, and the boosting block can change the pressure at different positions on the elastic tube, so that the range of action of the clean water is more comprehensive, thereby further improving the utilization rate of the clean water and enhancing the cleaning effect of the display screen.

[0012] Furthermore, it also includes a movable block, auxiliary parts symmetrically arranged on both sides of the movable block along the width direction of the movable block, and a moving unit for driving the movable block to perform reciprocating motion along the length direction of the box body; the auxiliary parts include a piston cylinder, a piston block, an inlet pipe, and an outlet pipe; the piston cylinder is fixedly connected to the side pipe; the piston block is slidably connected to the piston cylinder; the two ends of the movable block are respectively fixedly connected to the two piston blocks; the inlet pipe and the outlet pipe are both connected to the piston cylinder, and the inlet pipe and the outlet pipe are both located in the side pipe.

[0013] While the clean water is flowing in the side tube, the piston block and the piston cylinder cooperate with each other to increase the pressure of the clean water in the side tube, making the clean water flow faster and having a more comprehensive range when it is sprayed out from the moving tube, thereby further enhancing the force of the clean water and ensuring that the clean water can clean the display screen more fully.

[0014] Furthermore, it also includes a linkage part arranged on the movable block; the linkage part includes a linkage pipe, a plurality of linkage holes equidistantly opened on the linkage pipe along the length direction of the linkage pipe, and hoses respectively arranged at both ends of the linkage pipe; the linkage pipe is fixedly connected to the movable block; and the two ends of the hose are respectively connected to the linkage pipe and the side pipe.

[0015] While the clean water is sprayed from both sides of the display screen, the linkage pipe is set up so that the clean water can act on the display screen from top to bottom, thereby expanding the range of the clean water acting on the display screen, allowing the clean water to clean the display screen from different directions, thereby further enhancing the cleaning effect of the clean water on the display screen.

[0016] During the water discharge process, the linkage pipe can reciprocate along the length of the box body driven by the movable block. Therefore, through the reciprocating motion of the linkage pipe, the range of clean water discharge from top to bottom can be further expanded, thereby further improving the utilization rate of clean water, ensuring the effect of clean water spraying into the linkage pipe, and improving the cleaning efficiency of the clean water on the display screen.

[0017] Furthermore, it also includes a dispersion part symmetrically arranged at both ends of the display screen along the width direction of the display screen; the dispersion part includes a slider, a side plate, and a plurality of fixed blocks equidistantly arranged along the length direction of the side plate; the slider is fixedly connected to the side block; the side plate is fixedly connected to the slider; the fixed block is fixedly connected to the side plate, and the linkage hole is located on the motion trajectory of the fixed block.

[0018] During the reciprocating motion of the linkage pipe, the clean water sprayed from the linkage hole is diffused by the fixed block, so that the clean water can be dispersed under the action of the fixed block, making the range of the clean water from top to bottom more comprehensive, and the area where the clean water can contact the display screen is more sufficient, thereby further enhancing the cleaning efficiency of the clean water on the display screen.

[0019] Furthermore, the dispersion part also includes a shrinking tube unit; the shortening unit includes a second guide rod, a second nut seat, a fixed block, and a power part for driving the second nut seat to reciprocate along the length direction of the second guide rod; the second guide rod is fixedly connected to the box body; the second nut seat is slidably connected to the second guide rod; the fixed block is fixed to the second nut seat; it also includes a linkage part arranged on the linkage tube; the linkage part includes a filling block, a first spring, and a side hole opened on the linkage tube; the filling block is slidably connected to the side hole; the two ends of the first spring are respectively connected to the filling block and the linkage tube; the filling block is located on the movement trajectory of the fixed block.

[0020] During the movement of the movable tube, the second nut seat drives the fixed block to reciprocate along the length direction of the second guide rod. During the movement of the fixed block, the filling block is able to slide within the linkage tube under the combined action of the fixed block and the first spring. During the sliding of the filling block, the filling block can reduce the flow range of the clean water within the linkage tube, thereby increasing the flow pressure of the clean water within the linkage tube, so that when the clean water is discharged from the linkage hole, the flow speed of the clean water is faster and the force of the clean water is stronger, so that the clean water can clean the display screen more efficiently and thoroughly. That is, through the above-mentioned movement, the utilization rate of the clean water is further improved, the cleaning effect of the clean water is enhanced, and the clean water can be used to rinse the display screen more efficiently.

[0021] Furthermore, the drive unit includes a drive shaft, a first gear, and a first rack; the drive shaft is rotatably connected to the box; the first gear is fixed to the drive shaft; the first rack is fixed to the linkage tube; the first gear is meshed with the first rack; the slider is the second rack; and the second rack is meshed with the first gear.

[0022] During the reciprocating motion of the linkage tube, the first rack moves synchronously. During the motion of the first rack, it meshes with the first gear, causing the first gear to rotate. During the rotation of the first gear, the meshing of the first gear with the second rack enables the second rack to reciprocate along the width of the side tube.

[0023] Furthermore, the power unit is the second gear; the second gear is fixedly connected to the first screw; the side block is the third rack; and the third rack is meshed with the second gear.

[0024] During the movement of the third rack gear along with the second rack gear, the third rack gear meshes with the second gear gear, thereby causing the second gear gear to rotate. During the rotation of the second gear gear, the first screw gear rotates synchronously.

[0025] Furthermore, the motion unit includes a rotating shaft, a turntable, a pin shaft, a rotating shaft, a sector gear, a long block, a bar hole opened on the long block, and a moving part for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the box; the turntable is fixedly connected to the rotating shaft; the pin shaft is connected to the turntable; the rotating shaft is rotatably connected to the box; the sector gear is fixedly connected to the rotating shaft, the movable block is the fourth rack, and the sector gear is meshed with the fourth rack; the long block is fixedly connected to the sector gear; the pin shaft is slidably connected to the bar hole.

[0026] As the turntable rotates, the pin moves synchronously. Due to its sliding connection with the slotted hole, the pin drives the long block to oscillate during its circumferential motion. During the long block's oscillation, the sector gear moves synchronously. During this motion, the sector gear meshes with the fourth rack, causing the fourth rack to reciprocate along the length of the housing.

[0027] Furthermore, the power member is a second screw rod; the second screw rod is fixedly connected to the drive shaft; and the second nut seat is threadedly connected to the second screw rod.

[0053] Specific implementation process: When dust accumulates on display screen 2, clean water is directed into side pipe 5 via water tank 4 and ejected through several sliding holes 45. After being ejected through sliding holes 45, the clean water washes away the dust on display screen 2, thereby reducing dust accumulation and improving the cleanliness of display screen 2. This mechanical operation replaces manual labor, saving workers unnecessary trouble, enhancing the cleaning effect and efficiency of display screen 2, and preventing water splashing, which increases the environmental comfort during cleaning of display screen 2 and enhances the practicality of the device.

[0054] While clean water is being sprayed through the sliding hole 45, the motor 36 is activated, and the output shaft of the motor 36 drives the rotating shaft to rotate. During the rotating shaft's rotation, the turntable 31 rotates synchronously. During the rotation of the turntable 31, the pin 32 moves synchronously. During the movement of the pin 32, due to its sliding connection with the bar hole, the pin 32 can cause the long block 35 to oscillate during its circumferential motion. During the oscillation of the long block 35, the sector gear 34 moves synchronously. During the movement of the sector gear 34, due to its meshing with the fourth rack, the fourth rack can reciprocate along the length of the housing 3.

[0055] During the movement of the fourth rack, the first rack 28 moves synchronously. During the movement of the first rack 28, the first rack 28 meshes with the first gear 27, causing the first gear 27 to rotate. During the rotation of the first gear 27, the first gear 27 meshes with the second rack, allowing the second rack to reciprocate along the width of the side tube 5.

[0056] During the movement of the second rack, the third rack moves synchronously. During the movement of the third rack, the long board 7 moves synchronously. During the movement of the long board 7, the long board 7 can drive the movable tube 8 to reciprocate along the length of the slide hole 45. Therefore, through the reciprocating movement of the movable tube 8, the initial position of the clean water spray can be adjusted, allowing the clean water to reach a greater distance and clean the display screen 2 more comprehensively. Through this movement, during the period when the initial distance of the clean water spray changes, the clean water can be prompted to clean different positions of the display screen 2 more thoroughly and efficiently, further improving the cleanliness of the display screen 2 by the clean water.

[0057] During the movement of the movable tube 8, the third rack engages with the second gear 29, and the second gear 29 drives the first screw 9 to rotate. During the rotation of the first screw 9, the first screw 9 can drive the first nut seat 11 to reciprocate along the length direction of the first guide rod 10. During the movement of the first nut seat 11, the first nut seat 11 can drive the boosting block 13 to move toward the position where the elastic tube is located. During the movement of the boosting block 13, the elastic tube can be deformed under the action of the boosting block 13, and then the diameter of the elastic tube can be adjusted, so that when the clean water is sprayed out through the movable tube 8, it can act at a farther distance and a wider range, thereby ensuring that the clean water has a better cleaning effect on the display screen 2.

[0058] As the boosting block 13 approaches the position of the elastic tube, the elastic tube can change its position, and the boosting block 13 can change the pressure at different positions on the elastic tube, so that the range of action of the clean water is more comprehensive, thereby further improving the utilization rate of the clean water and enhancing the cleaning effect of the display screen 2.

[0059] While the clean water flows in the side tube 5, the four racks drive the two piston blocks 16 to reciprocate along the length direction of the side tube 5, and then the piston blocks 16 can cooperate with the piston cylinder 15 to increase the pressure of the clean water in the side tube 5, so that the clean water in the side tube 5 flows faster and has a more comprehensive range of action when sprayed out from the moving tube 8, thereby further enhancing the force of the clean water and ensuring that the clean water can clean the display screen 2 more fully.

[0060] While the clean water is being sprayed from both sides of the display screen 2, the clean water in the side tube 5 is directed into the linkage tube 17 under the pressure of the piston cylinder 15. The linkage tube 17 is provided to allow the clean water to act on the display screen 2 from top to bottom, thereby expanding the range of the clean water acting on the display screen 2, allowing the clean water to clean the display screen 2 from different directions, thereby further enhancing the cleaning effect of the clean water on the display screen 2.

[0061] During the water discharge process, the linkage pipe 17, driven by the fourth rack, can reciprocate along the length of the housing 3. Therefore, the reciprocating motion of the linkage pipe 17 can further expand the range of the clean water discharge from top to bottom, thereby further improving the utilization rate of the clean water and ensuring the effect of the clean water spraying out of the linkage pipe 17, that is, improving the cleaning efficiency of the display screen 2 with the clean water.

[0062] During the reciprocating motion of linkage tube 17, the second rack drives side plate 20 to reciprocate along the length of housing 3. During the motion of side plate 20, fixed block 21 moves synchronously. The reciprocating motion of fixed block 21 diffuses the clean water ejected from linkage hole 46. This disperses the clean water under the action of fixed block 21, ensuring a more comprehensive top-to-bottom contact area of ​​the clean water and a more comprehensive area of ​​contact with display screen 2, thereby further enhancing the cleaning efficiency of the clean water on display screen 2.

[0063] During the rotation of the drive shaft 26, the second screw 37 rotates synchronously. During the rotation of the second screw 37, the second screw 37 drives the second nut seat 23 to reciprocate along the length of the second guide rod 22. During the movement of the second nut seat 23, the fixed block 24 moves synchronously. During the movement of the fixed block 24, the filling block 25, under the combined action of the fixed block 24 and the first spring, is able to slide within the linkage tube 17. During the sliding of the filling block 25, the filling block 25 can reduce the flow range of the clean water within the linkage tube 17, thereby increasing the flow pressure of the clean water within the linkage tube 17. When the clean water is discharged from the linkage hole 46, the flow rate of the clean water is faster and the force of the clean water is stronger, thereby enabling the clean water to clean the display screen 2 more efficiently and thoroughly. In other words, through this movement, the utilization rate of the clean water is further improved, the cleaning effect of the clean water is enhanced, and the clean water can be used to rinse the display screen 2 more efficiently.

[0064] During the circumferential motion of the pin 32, the third gear 39 moves synchronously. During this motion, the third gear 39 meshes with the annular rack 38, thereby driving the pin 32 to rotate. During the rotation of the pin 32, the cam 41 rotates synchronously. During the rotation of the cam 41, when the raised portion of the cam 41 contacts the diffuser 42, the diffuser 42 moves vertically downward, compressing the second spring 44. When the raised portion of the cam 41 no longer contacts the diffuser 42, the diffuser 42 moves vertically upward under the action of the second spring 44. Therefore, while the diffuser 42 reciprocates circumferentially with the turntable 31, it also reciprocates vertically.

[0065] During the movement of the diffusion plate 42, the movable screen plate 43 moves synchronously. During the movement of the movable screen plate 43, the movable screen plate 43 can further expand the range of the clean water discharged from the linkage hole 46, so that the clean water has a higher degree of diffusion from top to bottom on the display screen 2, thereby promoting the clean water to clean the display screen 2 more fully and evenly, thereby comprehensively enhancing the cleansing effect of the clean water on the display screen 2 and ensuring the cleansing quality of the clean water from top to bottom.

[0066] To sum up, by cleaning the display screen 2 from both sides of the display screen 2 and cleaning the display screen 2 from top to bottom with clean water, on the one hand, the utilization rate of clean water is improved, ensuring that the clean water can comprehensively clean the display screen 2 from different directions; on the other hand, the cleaning effect of the display screen 2 is enhanced and the clarity of the display screen 2 is improved.
