Description

TECHNICAL FIELD

[0001] The application belongs to the field of highway water detection, and particularly relates to a highway tunnel bridge water depth warning device. BACKGROUND

[0002] The tunnel bridge is arranged on both sides of the highway for highway drainage, preventing the water accumulation of the highway and affecting the safety of vehicle driving; the highway tunnel bridge water depth warning device is a safety device for real-time monitoring and early warning of the water depth of low-lying sections such as tunnel bridges and underpasses. Through the water level sensor, data acquisition module and information publishing system, the water accumulation is dynamically detected, and warning information is published to the driver and pedestrians by using the LED display screen, sound and light alarm and other modes, so as to avoid the risk of wading and ensure the safety of road traffic.

[0003] At present, the existing highway tunnel bridge water depth warning device has some obvious problems in actual application. In rainy days, a large amount of rainwater with leaves, sundries and the like rushes to the water inlet, which easily causes the water inlet to be blocked, so that the device cannot timely and accurately obtain the water depth data, affecting the safety warning of passing vehicles and pedestrians. In sunny days, dry air will roll up dust and other impurities, which will enter the device inside along the water inlet, and long-term accumulation may damage the internal precision components of the device, interfere with the normal operation, reduce the service life and reliability of the device, and bring potential hidden dangers to the traffic safety of the tunnel bridge.

[0023] Please see Figures 1-6 As shown, the present invention is a warning device for the water depth of a highway underpass, comprising an inner cylinder 1, which is rotatably mounted on a mounting base 2. The inner cylinder 1 has a first water inlet 3. An outer cylinder 23 is rotatably mounted on the mounting base 2, and the outer cylinder 23 has a second water inlet 4, which corresponds to the first water inlet 3. A filter screen 5 is movably mounted on the second water inlet 4. A first threaded rod 6 is rotatably mounted on the mounting base 2. A cleaning ring 7 is threadedly connected to the first threaded rod 6. The cleaning ring 7 is in contact with the outer wall of the outer cylinder 23. An early warning mechanism is provided inside the inner cylinder 1, which is used to measure the water depth of the underpass.

[0024] The working principle of the highway underpass water depth warning device proposed in this invention is as follows: Rainy Day Work Mode: When water accumulates on the underpass, the outer cylinder 23 rotates to align its second inlet 4 with the first inlet 3 of the inner cylinder 1. The accumulated water flows in through the second inlet 4 of the outer cylinder 23, and after being filtered by the filter screen 5, the clean water enters the inner cylinder 1. The inner cylinder 1 can rotate freely, ensuring even water distribution and preventing impurities from accumulating.

[0025] Sunny Day Protection Mode: In dry weather, the outer cylinder 23 rotates to completely separate the second water inlet 4 from the first water inlet 3, forming a closed state, which effectively prevents dust, fallen leaves and other impurities from entering the device and keeps the inner cylinder 1 clean.

[0026] Self-cleaning function: The first threaded rod 6 on the mounting base 2 drives the cleaning ring 7 to move up and down along the outer wall of the outer cylinder 23, automatically removing debris attached to the surface of the outer cylinder and ensuring that the second water inlet 4 remains unobstructed for a long time.

[0027] Water level monitoring and early warning: The water entering the inner cylinder 1 triggers the internal early warning mechanism, which issues a warning signal of the corresponding level according to the height of the water rise, so as to promptly remind the management department and passing vehicles to pay attention to the water accumulation situation.

[0028] In one embodiment, for the first water inlet 3, there are several first water inlets 3 and several second water inlets 4. The several first water inlets 3 and several second water inlets 4 are arranged in a ring array and correspond one to one. There are several filter screens 5. The several filter screens 5 are detachably installed on the several second water inlets 4 through a snap-fit ​​structure.

[0029] In one embodiment, for the inner cylinder 1, the output end of the waterproof motor 8 is fixedly installed at the bottom of the inner cylinder 1. The waterproof motor 8 is fixedly installed in the inner sealed chamber of the mounting base 2 by bolts. A waterproof bearing is provided at the connection between the inner cylinder 1 and the mounting base 2.

[0030] In one embodiment, for the waterproof motor 8, the output end of the waterproof motor 8 is fixedly installed with a first transmission wheel 9 by a key connection, the first transmission wheel 9 is connected to a second transmission wheel 11 by a corrosion-resistant transmission belt 10, and the second transmission wheel 11 is rotatably installed on the internal bracket of the mounting base 2 by a bearing.

[0031] In one embodiment, for the first threaded rod 6, the first threaded rod 6 is fixedly connected to the second transmission wheel 11 by a coupling, and a limit plate 12 is fixedly installed at the end of the first threaded rod 6 away from the second transmission wheel 11. The inner side of the cleaning ring 7 is provided with a threaded hole that matches the first threaded rod 6.

[0032] The working principle of the highway underpass water depth warning device proposed in this invention is as follows: When the device is working, multiple first water inlets 3 and second water inlets 4 distributed in a ring array are opened simultaneously. Each second water inlet 4 is equipped with a filter screen 5 that can be detachably installed via a snap-fit ​​structure. The accumulated water enters the inner cylinder 1 through the filter screen 5 of the second water inlet 4 and the first water inlet 3 in sequence. The output end of a waterproof motor 8 is fixedly installed at the bottom of the inner cylinder 1 via a key connection. The waterproof motor 8 is fixedly installed in the internal sealed chamber of the mounting base 2 by bolts. A waterproof bearing is provided at the connection between the inner cylinder 1 and the mounting base 2. After the waterproof motor 8 is started, it drives the inner cylinder 1 to rotate on one hand, and drives the first transmission wheel 9 to rotate on the other hand through the output end. The first transmission wheel 9 drives the second transmission wheel 11 to rotate through a corrosion-resistant transmission belt 10. The second transmission wheel 11 drives the first threaded rod 6 to rotate through a coupling. When the first threaded rod 6 rotates, it drives the cleaning ring 7, which has a matching threaded hole on its inner side, to move up and down along the outer wall of the outer cylinder 23 for cleaning. A limit plate 12 is fixedly installed at the end of the first threaded rod 6 away from the second transmission wheel 11 to limit the range of motion of the cleaning ring 7. In the entire system, the waterproof motor 8 is installed in a sealed chamber to ensure waterproof performance, and a waterproof bearing is installed at the connection between the inner cylinder 1 and the mounting base 2. All transmission components are made of corrosion-resistant materials. The filter screen 5 can be quickly removed and replaced through a snap-fit ​​structure, and the corrosion-resistant transmission belt 10 and the connection components of each standardized interface facilitate daily maintenance.

[0033] In one embodiment, the warning mechanism includes a chute 13 disposed inside the inner cylinder 1. The chute 13 is symmetrically opened on both sides of the inner wall of the inner cylinder 1. A float 14 is slidably connected to the chute 13. The float 14 is made of foamed polyethylene material. A sensor head 15 is fixedly installed above the float 14.

[0034] In one embodiment, the sensing head 15 is connected to the sensing groove 16 by magnetic induction. The sensing groove 16 is disposed on the electromagnetic plate 17. The electromagnetic plate 17 is slidably connected to the inside of the inner cylinder 1 via a guide rail. A sealing ring is provided between the electromagnetic plate 17 and the inner cylinder 1.

[0035] In one embodiment, for the electromagnetic plate 17, one end of the electromagnetic plate 17 is rotatably mounted with a second threaded rod 18 via a thrust bearing, and the other end of the second threaded rod 18 is fixedly mounted with an anti-slip handle 19. The second threaded rod 18 is threadedly connected to the cover plate 20, and the cover plate 20 is slidably mounted above the inner cylinder 1 via a guide groove.

[0036] In one embodiment, a waterproof alarm light 21 is provided on the top of the cover plate 20. The alarm light 21 is electrically connected to the electromagnetic plate 17 through a waterproof wire. An expansion bolt 22 is provided through the upper surface of the mounting base 2, and a drainage channel is provided at the bottom of the mounting base 2.

[0037] The working principle of the flood depth warning device for highway underpasses proposed in this invention is as follows: when water enters the inner cylinder 1 through the first inlet 3, the rising water level pushes the float 14 to slide upward along the slide groove 13. The float 14 is made of foamed polyethylene material to ensure buoyancy stability. As the water level rises, the sensor head 15 fixed above the float 14 gradually approaches the sensor groove 16 on the electromagnetic plate 17. When the distance between the two reaches the magnetic induction threshold, an alarm signal is triggered.

[0038] The electromagnetic plate 17 is slidably connected to the inside of the inner cylinder 1 via a guide rail, and a sealing ring is provided between the electromagnetic plate 17 and the inner cylinder 1 to ensure waterproof performance. The electromagnetic plate 17 is connected to the second threaded rod 18 via a thrust bearing. Rotating the anti-slip handle 19 can drive the second threaded rod 18 to rotate, thereby adjusting the installation height of the electromagnetic plate 17 and realizing the flexible setting of the alarm water level threshold.

[0039] The cover plate 20 is slidably installed above the inner cylinder 1 via a guide groove and forms a threaded connection with the second threaded rod 18. When the sensor head 15 triggers the sensor groove 16, the electromagnetic plate 17 sends a signal to the waterproof alarm light 21 on the cover plate 20 via a waterproof wire, activating the audible and visual alarm.

[0040] The mounting base 2 is firmly fixed to the ground of the underpass by expansion bolts 22, and the drainage channel at its bottom can drain the water accumulated in the inner cylinder 1 during maintenance. The entire early warning mechanism achieves accurate monitoring and timely early warning of water depth through the coordinated work of the floating part 14 guided by the slide 13, the adjustable electromagnetic plate 17, and the waterproof alarm light 21.
