[0002] With the rapid development of our country, the construction speed of rail transit has accelerated. Subway vehicles have become an indispensable facility for people's travel. Subway maintenance equipment ensures the quality and safety of subway vehicles.

[0003] Therefore, it is necessary to timely predict the water levels at the entrances and exits of subway and rail transit stations, transition sections, and low-lying points during the flood season to avoid the backflow of rainwater and prevent casualties among the people.

[0004] At present, the water level monitoring device of subway rail transit needs to be set at the installation point for a long time, and the water inlet of the device is easily blocked by external debris or debris brought by water flow, which causes the external water flow to be unable to enter the monitoring device in time, making the water level inside the device inconsistent with the external water level, and thus unable to ensure that the monitoring device can accurately monitor the water level, and thus cannot provide timely and effective warnings. At the same time, it is easy to cause damage to the monitoring device, which is not conducive to the use of the device. Therefore, we propose a subway traffic water level alarm.

[0024] In a specific embodiment of the present invention, a porous filter plate is arranged at the inlet end of the water inlet channel 2, which can accommodate water passing through and prevent foreign matter from passing through. Ten vertical rods 21 are arranged at the bottom of the mounting ring 22, and each vertical rod 21 is vertically arranged with multiple cross rods 2101. The vertical area covered by the multiple cross rods 2101 can be larger than the vertical height of the porous filter plate. The horizontal seat of the L-shaped mounting frame 3 is fixedly connected to the bottom of the box body 1 by bolts. The number and position of the scraper rods 4 are consistent with the number and position of the cross rods 2101 of each vertical rod 21, so that when the mounting ring 22 rotates, the cross rod 2101 of each vertical rod 21 can accurately pass through the groove 401. The ring seat 18 and the ring seat 20 are distributed on the upper and lower sides of the mounting ring 22, and the balls are used to roll and support the mounting ring 22. Rotate, and use the arc groove to prevent the ball from running off track. The motor 16 includes a motor body and a reducer. The motor body is connected to the reducer. The output shaft of the reducer is connected to a gear 19. The gear is engaged with the ring teeth 2202 set on the circumferential surface of the mounting ring 22, so that the motor 16 drives the mounting ring 22, the vertical rod 21 and the horizontal rod 2101 to rotate as a whole. The battery provides power for the electrical equipment in the device (motor 16, water level detection component 15, buzzer 9 and warning light 14). The water level detection component 15 is a water level sensor or an infrared sensor, which needs to cooperate with the controller to process the signal of the water level sensor or the infrared sensor. When the controller receives the signal detected by the water level detection component 15, the switch module of the controller turns on the buzzer 9 and the warning light 14 for warning.

[0025] In the preferred technical solution, the anti-blocking mechanism also includes an L-shaped mounting frame 3, and a plurality of scraper rods 4 are equidistantly arranged on the inner side wall of the vertical rod of the L-shaped mounting frame 3, and a groove 401 is opened in the middle of the scraper rod 4. The number of scraper rods 4 on the L-shaped mounting frame 3 is consistent with the number of cross bars 2101 set outside each vertical rod 21, and the outer dimensions of the groove 401 match the outer dimensions of the cross bar 2101. The groove 401 and the cross bar 2101 are horizontally aligned to ensure that the cross bar 2101 can accurately pass through the groove 401 opened in the middle of the scraper rod 4. The groove 401 of the scraper rod 4 and the cross bar 2101 perform relative movement to achieve the crushing of bagged debris or directly hang the bagged debris on the surface of the scraper rod 4.

[0026] In the preferred technical solution, the top surface and the bottom surface of the mounting ring 22 are respectively provided with an arc groove 1 2201 and an arc groove 2 2203, and the inner wall of the outer shell 17 is respectively fixedly provided with a ring seat 18 and a ring seat 20, which are respectively located on the upper and lower sides of the mounting ring 22, and the bottom surface of the ring seat 18 and the top surface of the ring seat 20 are both provided with annular grooves, and a plurality of balls are inlaid inside the annular grooves, which are respectively located inside the arc groove 1 2201 and the arc groove 2 2203, and the arc grooves are used to prevent the balls from running off, and the provision of the ring seat 18, the ring seat 20 and the balls is conducive to the easy rotation of the mounting ring 22 as a whole.

[0027] In the preferred technical solution, slide grooves 7 are provided on both sides of the inner cavity 8, and sliders 5 are fixedly provided on both sides of the floating plate 6. The sliders 5 are embedded and slidably provided inside the slide grooves 7 to improve the stability of the floating plate 6 moving up and down.

[0028] In the preferred technical solution, the distance between the protective ring 10 and the exhaust port of the exhaust groove 11 is 20 mm, ensuring that the gas can be discharged from the gap between the protective ring 10 and the exhaust port of the exhaust groove 11, and at the same time the protective ring 10 shields and protects the exhaust port of the exhaust groove 11.

[0029] In the preferred technical solution, the water level detection component 15 is a water level sensor. When the water level sensor can be a float sensor, the floating plate 6 can trigger the water level sensor (float sensor) to change its value; the water level detection component 15 is an infrared sensor, and the floating plate 6 can trigger the infrared sensor to change its value. Therefore, as long as the floating plate 6 reaches the signal monitoring range of the water level detection component 15, it can trigger the controller to turn on the buzzer 9 and the warning light 14 for warning.

[0030] Working principle: When in use, the device is installed at the entrance and exit of a rail transit station, a line transition section, or a low-lying point on the line. When the water level at the rising position rises, water flows through the porous filter plate into the water inlet channel 2. As the external water level rises, the water in the water inlet channel 2 enters the inner cavity 8. The buoyancy of the water pushes the floating plate 6 to rise, and the slider 5 can slide along the slide groove 7. After the floating plate 6 is lifted, it reaches the signal monitoring range of the water level detection component 15. When the water level detection component 15 is a water level sensor (float sensor), the floating plate 6 can trigger the water level sensor (float sensor) to change its value. When the water level detection component 15 is an infrared sensor, the floating plate 6 can trigger the infrared sensor to change its value. Therefore, as long as the floating plate 6 reaches the signal monitoring range of the water level detection component 15, it can trigger the controller to turn on the buzzer 9 and the warning light 14 for warning.

[0031] By starting the motor 16 regularly, the bag-like objects in the water will accumulate on the surface of the cross bar 2101, and the motor 16 will drive the mounting ring to rotate as a whole. The bag-like debris hung on the cross bar 2101 passes through the scraper rod 4, and the groove 401 of the scraper rod 4 and the cross bar 2101 move relative to each other to break the bag-like debris, or the bag-like debris is directly hung on the surface of the scraper rod 4, thereby cleaning the bag-like debris hung on the cross bar 2101.
