[0012] The beneficial effects of this invention are:

[0013] (1) The intelligent anti-backflow device for underground public facilities of the present invention includes an interception structure for intercepting accumulated water connected to a pair of fixed columns, a manual control structure for manually controlling the interception of accumulated water connected to another fixed column, and a cleaning structure for cleaning dust connected to the fixed columns. The interception structure can block rainwater and prevent rainwater from entering the garage. The manual control structure can raise or lower the interception structure manually in case of power failure or device failure. The cleaning structure can clean one end of the fixed column when the interception structure is working, thereby ensuring the normal operation of the interception structure. That is: two fixed columns are installed at the entrance and exit of the garage, half of the fixed column is buried underground and half of the fixed column extends out of the ground. A water-blocking plate is slidably installed between the columns. Under normal conditions, the plate extends into the ground, with its top surface flush with the ground. During rainy weather, water accumulation can easily cause backflow into the garage. Liquid level sensors are installed on the fixed columns. When the sensor detects water level, it transmits a signal to the main unit. The main unit analyzes the electrical signal and makes a judgment. When the liquid level reaches a certain height, the main unit controls the motor to operate. The motor rotates, driving a rotating shaft. This shaft drives a first gear and a second gear, which in turn rotates a lead screw on one fixed column. This lead screw, through a second bevel gear, a first bevel gear, and a transmission shaft, drives a lead screw on another fixed column, causing both lead screws to rotate simultaneously. This drives the lifting rod upwards. Raising the water barrier protects the rotating shaft from damage caused by damp conditions. The protective tube protects the shaft and lead screw. The water barrier extends above ground, and the protective shell protects the underground end. Rubber strips and the water barrier are in close contact to prevent rainwater from entering the ground and causing malfunctions. With the water barrier raised, water is blocked outside, preventing it from flowing into the garage. In case of power failure or motor / main unit malfunction preventing control of the water barrier's raising and lowering, pushing the locking block compresses the first spring, disengaging the locking block from the slot. This allows the protective door to open. Pulling the handle outwards causes the fixing block to slide inside the rotating rod. When the fixing block reaches one end of the fixing slot, one end of the "H"-shaped fixing block will... Parallel to the hemispherical fixing groove, grasp the handle and push the control lever. The trapezoidal end of the control lever will move towards one end of the fixing block, causing it to sweep past the fixing block. The control lever will then push the fixing block into the fixing groove, compressing the second spring. Turning the handle will cause the rotating rod to rotate through the fixing block and fixing groove, thereby driving the fourth bevel gear to rotate, which in turn drives the third bevel gear and the rotating shaft to rotate, which in turn drives the lead screw to rotate, thus driving the raising and lowering of the water-blocking plate. When the handle is not pulled out, the fixing block is not in the fixing groove, and the fourth bevel gear will drive the rotating rod to rotate freely. When the water-blocking plate rises, it will drive the cleaning plate and scraper to rise. The torsion spring drives the brush at one end of the cleaning plate to contact the fixing post, thus ensuring the cleaning of the sliding parts of the water-blocking plate and the fixing post, and ensuring the normal operation of the device.The scraper helps to trap dust.

[0014] (2) The intelligent anti-backflow device for underground public facilities described in this invention has a camera structure connected to a fixed column for observing the situation around the garage. The camera structure can observe the environment around the garage in rainy weather and inform the owners in a timely manner. That is, a liftable and rotatable camera is also installed on the fixed column to observe the situation around the garage in a timely manner so as to inform the residents. The electric screw rod can drive the camera to lift and lower through the slide rod. The rubber ring can protect the slide rod to prevent rainwater from entering the fixed column. The camera can rotate to facilitate observation.

[0015] (3) The intelligent anti-backflow device for underground public facilities described in this invention has a climbing structure connected to a fixed column with a camera structure. The climbing structure is connected to a limiting structure for restricting its movement. The climbing structure allows personnel who have not left the garage in time to climb and leave when the intercepting structure is raised. The limiting structure makes the climbing structure more convenient to use. Specifically, when the water barrier is raised, the inclined end of the push block moves inward towards the interior of the fixed column, the third spring is compressed, and the grooved end of the push block pushes the limiting block to move. When the door is raised, pressing the groove end of the moving block will disengage it from the limiting block, thereby pushing the limiting block and the limiting groove to separate. The fourth spring will be compressed. When the water barrier is not raised, pressing the limiting block will disengage it from the limiting groove, thus facilitating the opening of the glass door in an emergency. A detachable ladder is also placed on the fixed column. If there are still personnel who need to evacuate in time, by pulling the handle of the glass door, the first and second magnetic blocks will disengage, and the ladder can be removed from the hanging rod. The personnel on the outside can take out the ladder on the outside, hang the top of the ladder on the hanging groove of the water barrier, and then climb to escape. Attached Figure Description

A water-blocking plate 201 is slidably installed between the two posts 1. Under normal conditions, the water-blocking plate 201 extends into the ground, with its top surface flush with the ground. During rainy weather, when water accumulates, the garage is prone to backflow. A liquid level sensor 205 is installed on each post 1. When the liquid level sensor 205 detects a water level, it transmits a signal to the host 211. The host 211 analyzes the electrical signal and makes a judgment. When the liquid level reaches a certain height, the host 211 controls the motor 206 to operate. The motor 206 rotates, driving the rotating shaft 207 to rotate. Shaft 207 drives the first gear 215 and the second gear 216 to rotate, which in turn drives the lead screw 209 on one fixed column 1 to rotate. The lead screw 209, through the second bevel gear 213, the first bevel gear 212, and the transmission shaft 208, drives the lead screw 209 on another fixed column 1 to rotate, so that both lead screws 209 rotate simultaneously, driving the lifting rod 210 to work upward, thereby raising the water barrier 201. The fixed shell 214 can protect the rotating shaft 207 to prevent the transmission shaft 208 from being damaged by the humid environment. The protective tube 202 can protect the transmission shaft 208 and the lead screw 209. The water barrier 201 extends out of the ground. The protective shell 203 can protect the end of the water barrier 201 that is underground. The rubber strip 204 and the water barrier 201... 1. A tight seal prevents rainwater from entering the ground and causing device malfunction. The water barrier 201 rises, blocking water from entering the garage. In case of power failure or damage to the motor 206 and main unit 211, preventing control of the water barrier 201's raising and lowering, push the locking block 503. The first spring 504 will compress, disengaging the locking block 503 from the locking slot 502, allowing the protective door 501 to open. Pull the handle 507 outwards. The handle 507 will cause the fixing block 511 to slide inside the rotating rod 510. When the fixing block 511 moves to one end of the fixing groove 513, one end of the "H"-shaped fixing block 511 will be parallel to the hemispherical fixing groove 513. At this point, grasp the handle 507 and push the control rod 506. The trapezoidal end of the control lever 506 will move towards one end of the fixed block 511, causing the trapezoidal end of the control lever 506 to sweep past the fixed block 511. The control lever 506 will push the fixed block 511 into the fixed groove 513, compressing the second spring 512. Turning the handle 507 will drive the rotating rod 510 to rotate through the fixed block 511 and the fixed groove 513, thereby driving the fourth bevel gear 509 to rotate, which in turn drives the third bevel gear 508 and the rotating shaft 505 to rotate, which in turn drives the lead screw 209 to rotate, thereby driving the water barrier 201 to rise and fall. When the handle 507 is not pulled out, the fixed block 511 is not in the fixed groove 513, and the fourth bevel gear 509 will drive the rotating rod 510 to rotate freely. When the water barrier 201 rises, it will drive the cleaning plate 701 and the scraper 703 to rise.The torsion spring 704 drives the brush 702 at one end of the cleaning plate 701 to abut against the fixed column 1, thereby ensuring the cleanliness of the sliding area between the water barrier 201 and the fixed column 1 and ensuring the normal operation of the device. The scraper 703 can intercept dust. A liftable and rotatable camera 301 is also installed on the fixed column 1, which can observe the situation around the garage in a timely manner so as to inform the residents. The electric screw 209 can drive the camera 301 to rise and fall through the slide bar 302. The rubber ring 303 can protect the slide bar 302 to prevent rainwater from entering the interior of the fixed column 1. The camera 301 can rotate for easy observation. When the water barrier 201 rises, it will push the inclined end of the push block 602 to move into the interior of the fixed column 1. The third spring 604 will compress the concave end of the push block 602. The groove end will push the limiting block 603 to move, and the groove end of the pressing block 602 will disengage from the limiting block 603, thereby pushing the limiting block 603 and the limiting groove 601 to separate. The fourth spring 605 will be compressed. When the water barrier 201 is not raised, the limiting block 603 can be pressed to disengage the limiting block 603 and the limiting groove 601, thus facilitating the opening of the glass door 401 in an emergency. A detachable ladder 402 is also placed on the fixed column 1. If there are still personnel who need to evacuate in time, the glass door 401 can be pulled by the handle 507, and the first magnetic block 404 and the second magnetic block 405 will disengage, allowing the ladder 402 to be removed from the hanging rod 407. The personnel on the outside can take out the outer ladder 402 and hang the top of the ladder 402 on the hanging groove 406 of the water barrier 201 for climbing and escape.
