AI Technical Summary
Existing urban road underpasses are prone to water accumulation on rainy days, causing inconvenience to vehicles. In addition, high-power water pumps are costly and energy-intensive, and frequent start-stop cycles shorten their lifespan, posing safety hazards.
A dual-channel water accumulation alarm system is adopted, including a first submersible pump, a second submersible pump, a controller, a display, and a level gauge. Automated drainage control is achieved through a manifold and steel grating. The first submersible pump drains water during light rain, while the second submersible pump increases the drainage volume during heavy rain. An alarm is triggered when the water level exceeds the limit.
It enables flexible and reliable drainage under different rainfall levels, reduces energy consumption and costs, ensures safe vehicle passage, and maintains a certain drainage capacity even when the pump is damaged, thereby improving the safety and reliability of the system.

[0015] Figure 2 It is Figure 1 Local enlarged view of part A in it. DETAILED DESCRIPTION
[0016] The technical scheme of the utility model will be further illustrated below in combination with specific embodiments. Figures 1-2 The technical scheme of the utility model will be further illustrated below in combination with specific embodiments.
[0017] As Figure 1 And Figure 2 The urban road underpass tunnel double-channel accumulated water alarm system shown in the figure is used for the treatment and alarm of accumulated water in underpass tunnel 1 under road 2, and includes: first submersible pump 11, second submersible pump 8, controller 3, display 4, first liquid level meter 5 and second liquid level meter 9, the bottom of underpass tunnel 1 is concavely provided with collector tank 6, for rainwater confluence, facilitating drainage. Collector tank 6 is arranged on one side or both sides of the bottom of underpass tunnel 1, in the embodiment, collector tank 6 is concavely arranged on both sides of the bottom of underpass tunnel 1, which does not affect the traffic of vehicles, and can efficiently confluence on both sides, reducing the accumulated water problem of underpass tunnel 1 in light rain.
[0018] Collector tank 6 top is provided with steel grating plate 7, and the strength of steel grating plate 7 is high, and the aperture is large, and the drainage effect is good, and it is not easy to block. In addition, even if steel grating plate 7 is blocked by garbage, it does not affect the work of second submersible pump 8, and the reliability is improved. AsFigure 2 As shown, the top of the collecting groove 6 is concave, and a clamping groove 10 corresponding to the steel grating plate 7 is arranged in the top of the collecting groove 6 to position the steel grating plate 7, facilitate the installation of the steel grating plate 7, and improve the positional stability.
[0019] The first submersible pump 11 and the first liquid level meter 5 are arranged in the collecting groove 6 respectively, and the water level in the collecting groove 6 is monitored by the first liquid level meter 5. In the embodiment, the top of the first submersible pump 11 is connected with the steel grating plate 7, and the top of the first submersible pump 11 can be fixed by installing screws in the steel grating plate 7 to avoid the inclination of the first submersible pump 11 and improve the stability during work.
[0020] As shown, Figure 2 The second liquid level meter 9 is arranged on the sidewall of the underpass tunnel 1 and extends upward from the bottom of the sidewall of the underpass tunnel 1 to monitor the water depth of the bottom surface of the underpass tunnel 1. The second liquid level meter 9 can be fixed on the sidewall of the underpass tunnel 1 by a support, and the structure is stable.
[0021] The second submersible pump 8 is arranged on one side of the bottom of the second liquid level meter 9, and in the embodiment, the second submersible pump 8 is fixed on the top of the steel grating plate 7 and can be fixed by screws to avoid the inclination of the second submersible pump 8.
[0022] The controller is arranged on the upper part of the sidewall of the underpass tunnel 1 or the side of the road 2 above the underpass tunnel 1 to ensure that it is far away from the water. In the embodiment, as shown, Figure 1 The display 4 is suspended above the underpass tunnel 1, and specifically, the display 4 is arranged on both sides of the road 2 above the underpass tunnel 1 and is fixed by a support to facilitate pedestrians and drivers to observe.
[0023] The controller 3 is connected with the first submersible pump 11, the second submersible pump 8, the display 4, the first liquid level meter 5 and the second liquid level meter 9 respectively to control the automatic drainage. In the case of light rain, rainwater enters the collecting groove 6, and when the liquid level in the collecting groove 6 rises to half the height of the collecting groove 6, the controller 3 triggers the work of the first submersible pump 11 to drain water, and at this time, the second submersible pump 8 does not need to work, thereby reducing the energy consumption and cost.
[0024] When the rainfall is large, the first submersible pump 11 cannot drain water in time, and the water in the underpass tunnel 1 rises above the steel grating plate 7. When the second liquid level meter 9 detects that the water level rises above 10 cm above the steel grating plate 7, the controller 3 triggers the work of the second submersible pump 8 to increase the drainage capacity, timely eliminate the water, ensure the safe passage of vehicles, and display the real-time water level data obtained by the second liquid level meter 9 through the display 4.
[0025] When the water level exceeds 30 cm above the steel grating plate 7, an alarm is given, a red light or a display of forbidden passage is given by the display 4, and double-channel water accumulation treatment is realized by the first submersible pump 11 and the second submersible pump 8, which is more flexible, and after the first submersible pump 11 or the second submersible pump 8 is damaged, a certain drainage capacity can still be ensured, thereby improving the safety and reliability of use.
[0026] The above merely describes the preferred embodiments of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation manner and application range can be changed, and the content of the specification should not be understood as limiting the present application.
