Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a bridge flood level alarm device. Background Technology

[0002] Bridges, as structures spanning terrain and rivers, play a crucial role in the integrity and connectivity of roads. For the most common type of bridge, beam bridges, the piers are often placed in the riverbed when crossing rivers. During the flood season, heavy rainfall causes river levels to rise, potentially exceeding the design flood level, severely impacting the bridge's overall structure and threatening road safety. Therefore, timely warnings and appropriate emergency measures when river levels exceed the design flood level are of paramount importance for improving bridge operational safety.

[0003] The traditional method involves spraying warning water level lines on bridge piers, and issuing warnings by personnel when the water level exceeds the warning level. This method has the following drawbacks: (1) visibility is limited on rainy days, and the sprayed water level is often not clearly visible; (2) personnel may make errors in observing the water level, affecting decision-making; (3) personnel with certain professional knowledge are required to observe and judge in order to obtain warning information, and it is not possible to quickly and intuitively prompt vehicles.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings:

[0021] like Figure 1The bridge flood level alarm device shown includes a conductive module 1, which is installed on the bridge pier. The conductive module 1 is at the same elevation as the bridge flood warning position. A warning light 2 connected to the conductive module 1 is installed on the bridge. A power supply 3 is connected to the circuit between the warning light 2 and the conductive module 1. The warning light 2 can be a multi-color variable warning light. The number of warning lights 2 can be set appropriately according to the length of the bridge deck and connected in parallel. The purpose is to ensure that road inspectors and drivers can clearly see the flood warning given by the flashing warning lights 2.

[0022] In this embodiment, the conductive module 1 includes an insulating shell 4 with a through-hole in the middle. Metal conductors 5 are installed on both sides of the insulating shell 4, and each metal conductor 5 is connected to a wire 6.

[0023] In this embodiment, the insulating housing 4 has receiving cavities 7 on both sides for mounting the metal conductor 5. The receiving cavities 7 are open at both the top and bottom, and the top and bottom ends of the metal conductor 5 are flush with the top and bottom ends of the receiving cavities 7, respectively. Figure 2 As shown.

[0024] It should be further noted that installing the metal conductor 5 within the cavity 7 of the insulating housing 4 is just one of the conventional installation methods. The metal conductor 5 can also be a thin metal sheet, directly installed on both sides of the insulating housing 1. The two metal conductors do not need to be on the same plane, as long as they are at the same elevation as the bridge flood warning position when conducting. If the wire 6 used for connecting the metal conductor 5 passes directly through the insulating housing 4, it needs to be sealed.

[0025] In this embodiment, the insulating shell is generally square in structure. The insulating shell 4 can also adopt other structural forms that meet the requirements, and it can be fastened to the bridge pier by any means such as bonding or bolting.

[0026] In this embodiment, a control switch 8 is also connected within the connecting circuit.

[0027] In this embodiment, the control switch 8 is installed on the bridge deck. The purpose of providing the control switch 8 is to facilitate the maintenance of the alarm device.

[0028] In this embodiment, the power supply 3 is powered by a battery or a solar panel. Using a battery for direct power supply in this embodiment saves on initial investment costs.

[0029] The alarm device uses the principle of water flow conductivity to design and position the conductive module 1. The principle is simple and the effect is reliable. It uses light warning to avoid errors caused by human observation, reduces the professional knowledge requirements of the observer, and has a wider range of applications. The warning light and control switch are placed on the bridge surface for easy operation and maintenance.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
