Description

Technical Field

[0001] This utility model relates to the field of bridge drainage technology, and in particular to a rainwater harvesting and power generation system for super-large bridge decks. Background Technology

[0002] Highway bridges with a total span of more than 1,000m or a single span of more than 150m are usually referred to as extra-large bridges.

[0003] The main span of the super-large bridge adopts a long-span bridge structure, with a span exceeding conventional bridge design standards, in order to meet the requirements of waterway traffic capacity and ensure the safe passage of large ships.

[0004] The design of this type of super-large bridge significantly increases the height of the bridge deck, creating a large height difference with the roads on both sides. The maximum height difference between the bridge deck and the ground is more than ten meters. The pipes installed at the bridgehead need to adapt to the steep slope changes, resulting in rainwater flowing at extremely high speeds under the influence of gravity.

[0005] The high-speed flow of rainwater not only places stringent requirements on the structural strength of the pipeline, but also increases the difficulty of fluid dynamics control and safety management.

[0006] Traditional drop wells can only handle drops of up to 8 meters and only have a physical energy dissipation function. The high-speed water flow energy is not effectively utilized, resulting in energy waste.

[0007] To address the common technical challenges of the aforementioned mega-bridges, current conventional designs typically incorporate energy-dissipating structures, such as energy dissipation pools or drop structures, at both ends of the bridge. These structures reduce the flow velocity to a safe range by altering the fluid flow direction and increasing flow resistance, thereby preventing impact damage to downstream pipelines or equipment.

[0008] However, since rainwater on the bridge surface is collected through pipes and falls to the ground, the large drop in the pipes generates a certain amount of potential and kinetic energy. If the energy is dissipated through an energy dissipation pool or a drop well before being discharged into the water, this part of the energy cannot be fully utilized.

[0009] Therefore, how to effectively utilize the potential energy of rainwater generated by the drop in the pipeline of a super-large bridge, while effectively dissipating energy through cascading water, and avoiding its direct waste, has become a technical problem that urgently needs to be solved by those skilled in the art.

[0012] The turbine of the turbine power generation device is installed in the inlet channel at the front end of the emergency pool of the bridge and is driven to rotate by rainwater entering from the inlet pipe of the emergency pool.

[0013] One end of the water inlet pipe is located above the turbine, and the other end is connected to the bridge deck rainwater pipe network, so as to guide the rainwater in the bridge deck rainwater pipe network to drive the turbine to rotate;

[0014] The distance from the lower end of the turbine to the bottom of the emergency pool meets the requirements for energy dissipation from the cascading water.

[0015] Preferably, it also includes a battery storage device for storing the electricity generated by the turbine generator.

[0016] More preferably, it also includes a warning light or a maintenance spotlight installed in the emergency pool; the warning light or maintenance spotlight is powered by the battery storage device.

[0017] More preferably, the emergency pool is provided with a square gate on the indoor side wall and a round gate at the location of the water outlet pipe; both the square gate and the round gate are manual and electric gates, and are powered by the battery storage device.

[0018] More preferably, both the square gate and the round gate are cast iron gates inlaid with copper.
