With the development of society, resources are becoming increasingly scarce, especially electricity resources, which cannot meet people's needs. How to fully utilize the mechanical energy that occurs in daily life and convert it into electrical energy is an issue that modern technology urgently needs to solve.

[0003] With the development of cities, urban overpasses are increasing. Rainwater on bridge decks is often discharged directly into municipal rainwater pipes through pipes installed on bridge piers. Urban overpasses are often more than ten meters high, and the mechanical energy of the falling rainwater is not fully utilized.

[0004] At the same time, the bridge deck drainage in existing urban bridges is basically collected through PVC pipes and discharged directly into the municipal rainwater pipes. The PVC pipes leak outside the bridge body and piers, which not only affects the urban landscape, but also makes the PVC pipes prone to aging and damage in the open air environment.

[0031] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] like Figures 1 to 5 As shown, the preferred embodiment of the utility model provides a bridge deck drainage and energy storage system, which includes a bridge 1, a drainage pipeline 2 and a recovery module 3;

[0033] The bridge 1 includes a bridge body 11 and a bridge pier 12. A rainwater channel opening for discharging rainwater is provided on the side of the top surface of the bridge body 11. The rainwater channel 111 is connected to the drainage pipe 2. A limiting groove 121 is provided on the side of the bridge pier 12. The drainage pipe 2 is limitedly arranged in the limiting groove 121.

[0034] The drainage pipeline 2 includes a first pipeline 21 and a second pipeline 22 which are connected in sequence. The first pipeline 21 is fixedly connected to the bridge body 11 and connected to the rainwater channel 111. The second pipeline 22 is arranged in the limiting groove 121 and fixedly connected to the bridge pier 12. The water outlet of the second pipeline 22 is connected to the energy dissipation pool 4 which is hidden and arranged underground.

[0035] The recovery module 3 includes a plurality of power generation modules 31 detachably connected to the second pipeline 22 and a power storage module 32 disposed in the energy dissipation pool 4 . The power storage module 32 is electrically connected to the power generation module 31 . The power storage module 32 is also electrically connected to the output module 33 .

[0036] Specifically, in the case of waterlogging on the bridge due to heavy rain, in the utility model, rainwater on the bridge deck is collected through the rainwater channel 111 to quickly discharge the rainwater and prevent rainwater from accumulating on the bridge deck and affecting traffic safety. The collected rainwater is at a high altitude from the ground and has more gravitational potential energy, which can be collected for utilization. The accumulated water on the bridge deck enters the drainage pipe 2 through the rainwater channel 111 and flows through the first pipe 21 and the second pipe 22 in sequence. The second pipe 22 is connected to a plurality of power generation modules 31. When the rainwater flows through the power generation module 31, it drives the power generation elements in the power generation module 31, thereby converting the potential energy of the rainwater into electrical energy. The plurality of power generation modules 31 can recover the potential energy of the rainwater in sections, and the recovery efficiency is higher. The detachable setting of the power generation module 31 enables some of the power generation modules 31 to be quickly disassembled for repair and replacement when damaged, which does not affect the recovery efficiency of the rainwater potential energy and is more convenient for maintenance. The energy dissipation pool 4 is arranged between the drainage pipeline 2 and the municipal pipeline, avoiding the direct connection between the drainage pipeline 2 and the municipal pipeline. The energy dissipation pool 4 can receive a large amount of rainwater discharged from the drainage pipeline 2 and reduce the impact of rainwater, avoiding a large amount of rainwater from pouring into the municipal pipeline to exert excessive drainage pressure on the municipal pipeline and avoid damaging the municipal pipeline. The energy dissipation pool 4 arranged underground can also ensure the smoothness of the road surface under the bridge, avoid the appearance of buildings higher than the ground, and its construction cost will be lower. The power storage module 32 is arranged in the energy dissipation pool 4, which can also ensure the smoothness of the road surface under the bridge, and can also avoid the adverse effects of the external environment or traffic accidents on the power storage module 32. The setting of the limit groove 121 can protect the drainage pipeline 2, increase the service life of the drainage pipeline 2, and avoid the rapid aging and damage of the drainage pipeline 2 in the external environment.

[0037] In some embodiments, rainwater channels 111 , limiting grooves 121 and drainage pipes 2 are provided on both lateral sides of the bridge 1 .

[0038] Specifically, the rainwater channel 111 and the drainage pipe 42 are arranged on both sides of the bridge 1 to better and more comprehensively collect the rainwater on the bridge deck, further improve the recovery efficiency of the rainwater potential energy, and avoid the rainwater on the other side of the bridge 1 not being recycled and processed, and the potential energy of the rainwater on the other side of the bridge 1 is wasted. Furthermore, in addition to the limit groove 121 provided on the pier 12, the limit groove 121 is also provided on the bottom surface of the bridge body 11 to limit and fix the first pipeline 21 to prevent the position of the first pipeline 21 from being offset.

[0039] In some embodiments, a water collecting trough 113 extending along the length direction of the bridge body 11 is provided on the side of the bridge body 11 , the bottom surface of the water collecting trough 113 is inclined and the rainwater channel 111 is provided at the lowest point, and a filter screen 112 is provided at the water inlet of the rainwater channel 111 .

[0040] Specifically, the rainwater in the middle of the bridge 1 flows toward both sides of the bridge 1 and enters the water collection tank 113. The water collection tank 113 can gather the rainwater in the bridge 1 in one place and enter the drainage pipe 42 221 through the rainwater channel 111, thereby fully improving the recovery efficiency of the rainwater potential energy. The filter screen 112 set at the water inlet of the rainwater channel 111 can prevent the debris on the bridge deck from entering the drainage pipe 42 221 through the rainwater channel 111, thereby blocking the drainage pipe 42 221, and even causing a destructive effect on the power generation module 31. Furthermore, the diameter of the end of the first pipeline 21 close to the rainwater channel 111 is larger than the diameter of the middle part of the first pipeline 21, and its end presents a frustum structure, thereby increasing the flow rate of the water flow passing through the power generation module 31, thereby improving the power generation efficiency of the power generation module 31.

[0041] In some embodiments, an arc-shaped limiting card 1211 is fixed in the limiting groove 121 by an anchor bolt, and the second pipeline 22 is embedded in the groove of the limiting card 1211; a baffle 1212 is detachably provided at the opening of the limiting groove 121, and the second pipeline 22 is arranged between the baffle 1212 and the limiting card 1211.

[0042] A gap is provided between the limiting card 1211 and the limiting slot 121 ; and an opening angle of the limiting card 1211 is between 150° and 190°.

[0043] Specifically, the limit card 1211 and the second pipeline 22 are interference fit, and a gap is reserved between the limit card 1211 and the limit groove 121. During the installation of the second pipeline 22, the second pipeline 22 is inserted into the groove of the limit card 1211, and the limit card 1211 is deformed and firmly locks the limited second pipeline 22 to prevent the second pipeline 22 from being offset and causing rainwater to be unable to flow smoothly, affecting the recovery of rainwater potential energy. When the second pipeline 22 needs to be disassembled, the second pipeline 22 can be directly pulled outward, so that the second pipeline 22 can be disassembled and replaced more conveniently. The setting of the baffle 1212 can provide more comprehensive protection for the second pipeline 22 to prevent damage to the second pipeline 22 by external dust, stones, ultraviolet rays, etc. The opening angle of the limit card 1211 is limited between 150° and 190°, which can better limit the second pipeline 22. If the angle is too small, it cannot provide sufficient deformation force to limit the second pipeline 22, and if the angle is too large, it will make the installation and disassembly of the second pipeline 22 difficult.

[0044] In some embodiments, a detachable inspection elbow 23 is provided between the first pipeline 21 and the second pipeline 22 , and two ends of the inspection elbow 23 are respectively connected to the first pipeline 21 and the second pipeline 22 .

[0045] Specifically, when the drainage pipeline 2 is blocked, the inspection elbow 23 can be quickly removed, thereby facilitating the staff to clear and inspect the first pipeline 21 and the second pipeline 22.

[0046] In some embodiments, a sand settling area 41 is provided at the bottom of the energy dissipation pool 4, and the bottom surface of the sand settling area 41 is inclined; a drainage pipe 42 connected to the municipal pipeline is provided at the top of the sand settling area 41.

[0047] Specifically, the setting of the sand settling area 41 can provide a better buffering effect for the rainwater discharged from the drainage pipe 2, and reduce the impact of rainwater on the energy dissipation pool 4. In addition, the setting of the sand settling area 41 also facilitates the sedimentation of fine particles such as mud and sand in the rainwater, and prevents fine particles such as mud and sand from entering the municipal pipeline through the drainage pipe 42 with rainwater, causing excessive pressure on the drainage of the municipal pipeline.

[0048] In some embodiments, the second pipeline 22 includes multiple sections of pipelines 221, and the power generation module 31 is disposed between adjacent pipelines 221 along the axis of the second pipeline 22;

[0049] The power generation module 31 includes a shell 311 and a micro-hydraulic turbine generator 312 disposed in the shell 311 ; both upper and lower ends of the shell 311 are provided with bayonet holes 3111 for detachably connecting with the pipeline 221 .

[0050] Specifically, the second pipeline 22 is a segmented structure, which includes a plurality of pipes 221, and the adjacent pipes 221 are connected with power generation modules 31, and the plurality of power generation modules 31 arranged in sequence from top to bottom can fully utilize the potential energy of falling rainwater to generate electricity, and the rainwater recovery efficiency is naturally higher, and the impact of falling rainwater is also reduced, so as to avoid excessive potential energy of rainwater from damaging the bottom power generation module 31. The bayonet 3111 at the upper and lower ends of the shell 311 of the power generation module 31 realizes the detachable connection between the power generation module 31 and the pipe 221. When the power generation module 31 is damaged or blocked, the damaged or blocked power generation module 31 can be quickly disassembled for repair and replacement, so as to maintain the continuous work of rainwater potential energy recovery, thereby improving the recovery efficiency; in addition, a waterproof sealing ring and other structures are also provided between the bayonet 3111 and the pipe 221 during the actual connection process to improve the sealing performance.

[0051] Furthermore, an upper water inlet 313 and a lower water inlet are provided in the shell 311. The upper water inlet 313 and the lower water outlet 314 are both conical structures. One end of the upper water inlet 313 is connected to the upper clamp 3111, and the other end is connected to the micro-hydraulic turbine generator 312, which can increase the flow rate of rainwater entering the micro-hydraulic turbine generator 312, thereby improving the potential energy recovery efficiency; and one end of the lower water outlet 314 is connected to the lower clamp 3111, and the other end is connected to the micro-hydraulic turbine generator 312, which can reduce the pressure in the pipeline 221, so that the rainwater can flow downward to the next power generation module 31 more smoothly.

[0052] In some embodiments, the output module 33 includes a plurality of charging posts 331 arranged side by side under the bridge 1. Specifically, the output module 33 can be configured as a plurality of car charging posts 331 arranged side by side, and used in conjunction with the parking lot between the piers 12 to fully utilize the recovered electric energy.

[0053] In some embodiments, the power storage module 32 is also electrically connected to the street lamp 5 provided on the bridge 1 and the solar panel 51 provided on the street lamp 5. The solar panel 51 on the street lamp 5 can absorb the energy of sunlight on sunny days to convert it into electrical energy and store it in the power storage module 32. At night, the power storage module 32 uniformly distributes electrical energy to each street lamp 5 to avoid the problem that some street lamps 5 cannot be illuminated at night due to damage to the solar panel 51; in addition, the solar panel 51 is used in conjunction with the rainwater potential energy recovery power generation device to cover most weather conditions, and the recovery efficiency and recovery range of its clean energy are also better.

[0054] In summary, the embodiment of the utility model provides a bridge deck drainage and energy storage system, which has multiple power generation modules 31 arranged in sections on the second pipeline 22, which can not only recover the potential energy of rainwater in sections, thereby improving the recovery efficiency of rainwater potential energy, but also facilitate the inspection, maintenance and replacement of the power generation modules 31. The structure is simpler, easier to repair and lower in cost. In addition, it can reduce the impact of rainwater on the bottom power generation module 31, thereby avoiding damage to the bottom power generation module 31 due to long-term and large impact.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
