Description

Technical Field

[0001] This utility model relates to the field of subway flood control technology, specifically to an automatic sensing flood-proof barrier at subway entrances and exits. Background Technology

[0002] Due to the increasing impact of human factors on the natural environment, extreme weather events in the region are on the rise, and the number and losses from floods are increasing year by year. The construction of flood control dikes is becoming increasingly important in urban development. Subways are located underground in low-lying areas, making it even more necessary to prevent flooding in advance. Flood barriers should be placed behind the drainage channels at subway entrances and exits, closer to the escalators. When the water level is high, some floating objects will approach. However, some existing flood control barriers can only be erected to block floodwaters and are not convenient for guiding floating objects. For example, floating objects such as water tanks may cross the barriers and may slide down the escalators, making it inconvenient to protect staff and use. Utility Model Content

A mounting plate 12 is fixed to the rear of the pedal 11. A buffer seat 13 is fixed to the rear of the mounting plate 12. A cross brace 14 is fixed between the two inner walls of the support base 1. An electric push rod 15 is rotatably connected between the two inner walls of the cross brace 14. The output end of the electric push rod 15 is rotatably connected to the rear of the mounting plate 12. A retaining seat 2 is slidably connected inside the buffer seat 13. Two rectangular... A rectangular rod 21 passes through the buffer seat 13 and extends to the top. A guide plate 22 is rotatably connected to the top of the rectangular rod 21. A power mechanism 3 for adjusting the two guide plates 22 is provided inside the buffer seat 13. An energy storage mechanism 4 is provided on both sides of the support seat 1. A mounting bracket 16 is fixedly connected to both sides of the support seat 1. The mounting bracket 16 is used to fix the support seat 1 with bolts. A protective plate 111 is fixedly embedded in the front side of the pedal 11. A mounting groove 18 is opened on the front side of the mounting plate 12. On one inner wall of the mounting groove 18... An ultrasonic level sensor 19 is fixedly connected to the platform 11. The protective plate 111 is made of tempered glass. The ultrasonic level sensor 19 can monitor the water level in front of the platform 11 in real time, thus providing water level information during monitoring. A warning light strip 5 and a 4G communication module 52 are fixedly connected to the inner wall of the mounting groove 18. A voice module 51 is fixedly connected to the inner top wall of the mounting groove 18, and an tilt sensor 53 is fixedly connected to the inner bottom wall of the mounting groove 18. When the platform 11 is erected, the warning light strip 5 can be activated to warn pedestrians of the danger and provide guidance to staff. The system provides guidance and can send information from the vehicle control room via the 4G communication module 52. It can also broadcast voice messages via the voice module 51 to provide guidance or assistance to pedestrians and staff. The tilt sensor 53 can monitor the tilt of the pedal 11 in real time and monitor the status of the support seat 1 in real time. The rectangular rod 21 is rotatably connected to the shaft 23. The top of the shaft 23 is fixed to the guide plate 22, and the bottom of the shaft 23 passes through the card seat 2 and extends into it. The rotation limit of the shaft 23 by the rectangular rod 21 is achieved to limit the rotation of the guide plate 22.

[0026] The power mechanism 3 includes two electric push rods 31 fixedly connected to the inner wall of the buffer seat 13. The buffer seat 13 has a groove 131 inside. The card seat 2 is slidably connected between the two inner walls of the groove 131. The output end of the electric push rod 31 is fixedly connected to the bottom of the card seat 2. A motor 32 is fixedly connected to the inner bottom wall of the card seat 2. The output end of the motor 32 is fixedly connected to the bottom end of the adjacent shaft 23. Pulleys 33 are fixedly sleeved on the outer walls of the two shafts 23. The two pulleys 33 are connected by belt drive. The card seat 2 is slidably limited by the groove 131. Starting the electric push rod 31 can drive the card seat 2 to move up and down, which determines whether the guide plate 22 is lifted out or put away. Starting the motor 32 can drive the adjacent shaft 23 and the guide plate 22 to rotate, and drive the other guide plate 22 to rotate synchronously through the transmission of the two pulleys 33.

[0027] The energy storage mechanism 4 includes a limiting seat 41 fixed to the outer wall of the support base 1. A rectangular groove 42 is provided on the top of the limiting seat 41. A protective plate 44 and a solar panel 43 are fixed between the two inner walls of the rectangular groove 42. A battery 45 is fixed to the inner bottom wall of the rectangular groove 42. The protective plate 44 is made of tempered glass, which can protect the internal components of the rectangular groove 42 and ensure normal light transmission. Under normal weather conditions, the solar panel 43 can generate electricity by sensing light and store electrical energy through the battery 45. The electrical energy can be used for flood control. A protective shell 17 is fixed inside the mounting bracket 16. One end of the protective shell 17 passes through the limiting seat 41 and extends into the rectangular groove 42. A wiring groove 121 is provided inside the mounting plate 12. The top of the wiring groove 121 is connected to the mounting groove 18. The protective shell 17 can protect the wiring and create a wiring space for each component, thereby realizing the electrical connection with the battery 45.

[0028] By rotating a guide plate 22 at the top of the rectangular rod 21, when the ultrasonic level sensor 19 senses that the water accumulation in front of the pedal 11 is deep, the electric push rod 31 can be activated to raise the two rectangular rods 21 to help block floating objects. The motor 32 can be activated to drive the two guide plates 22 to rotate, thereby moving the floating objects away from the pedal 11. This facilitates the guidance of floating objects, reduces the risk of floating objects crossing the barrier, and provides protection for workers. It is also convenient to use.

[0029] On sunny days, sunlight can shine through the protective plate 44 into the rectangular groove 42, where the solar panel 43 is a photosensitive point and stores electrical energy through the battery 45. When the subway staff judges that flood storage is imminent, they can activate the electric push rod 15 to rotate the mounting plate 12 and the pedal 11 to a vertical position. Multiple pedals 11 work together to form a barrier to block the flood.

[0030] When the pedal 11 is erected, the warning light strip 5 can be activated to warn pedestrians of the danger and guide staff. Information can also be sent from the vehicle control room via the 4G communication module 52 and voice broadcast via the voice module 51 to provide guidance or assistance to pedestrians and staff. The tilt sensor 53 can monitor the tilt of the pedal 11 in real time and can monitor the status of the support seat 1 in real time.

[0031] The ultrasonic level sensor 19 can monitor the water level in front of the pedal 11 in real time, thus providing water level information during monitoring. When the water level is high, there is a risk that nearby floating objects may cross the pedal 11. The two electric push rods 31 can be activated to lift the bracket 2, exposing the two rectangular rods 21 and the guide plate 22. While the rectangular rods 21 block the floating objects, the motor 32 can be activated to drive the adjacent shaft rod 23 and the guide plate 22 to rotate. Through the transmission of the two pulleys 33, the other guide plate 22 can be driven to rotate synchronously. The guide plate 22 can push the nearby floating objects away, preventing the floating objects from crossing the pedal 11 and sliding into the escalator.
