Description

Technical Field

[0001] This utility model relates to the field of building engineering, and more specifically, to a rainwater filtration and recycling device for under-bridge space and a bridge. Background Technology

[0002] In bridge engineering, especially during rainy weather, urban bridge decks often accumulate significant amounts of water. Due to the structural characteristics and material properties of urban bridges, some of this water seeps through gaps in the bridge structure to the underside. This seepage phenomenon is prevalent in many bridges, posing numerous hazards to bridge safety and the surrounding environment. On one hand, long-term seepage erodes the bridge structure, leading to problems such as steel reinforcement corrosion and concrete deterioration, reducing the bridge's load-bearing capacity and service life. On the other hand, rainwater seeping to the underside of the bridge accumulates, affecting traffic and pedestrian passage.

[0003] In practical bridge applications, existing technologies have significant shortcomings in addressing the problem of water seepage under bridges. During the development of this invention, the inventors discovered at least the following issues with existing technologies: 1) From a resource waste perspective, rainwater seeping to the bottom of bridges is directly drained away without effective utilization. This waste is particularly pronounced in water-scarce areas. For example, in urban bridges, large amounts of rainwater are wasted, while urban greening and cleaning require significant amounts of tap water, resulting in an unreasonable allocation of water resources. The main reason for this problem is the lack of emphasis on rainwater resources and effective recycling methods in existing technologies; 2) Water seeping under urban bridges corrodes the supporting columns, which can damage the safety of urban bridges in the long run; 3) Water seepage under urban bridges affects the utilization of the space beneath them. Therefore, a rainwater filtration and recycling device for the space under bridges is urgently needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a rainwater filtration and recycling device for the space under bridges, which aims to improve the problem of water seepage at the bottom of urban bridges causing damage in the existing technology.

[0005] Through long-term exploration and experimentation, as well as numerous trials and efforts, the inventors have continuously reformed and innovated to solve the above-mentioned technical problems. The technical solution provided by this utility model is as follows:

[0009] In some embodiments of this utility model, the water outlet component includes a water outlet pipe and a valve, with the valve disposed on the water outlet pipe.

[0010] In some embodiments of this utility model, the outer surface of one end of the conduit located inside the filter bucket abuts against the inner surface of the filter bucket.

The water inlet pipe is connected to the water inlet of the water storage tank, and one end of the water inlet pipe near the water inlet of the water storage tank extends towards the bottom wall of the water storage tank and is arranged inside the water storage tank.

[0012] In some embodiments of this utility model, the filter bucket is provided with at least two support blocks, and the filter screen is placed on the support blocks inside the filter bucket.

[0013] In some embodiments of this utility model, the filter screen is provided with a pull ring, which is located on the side away from the bottom of the filter hopper.

[0014] Another technical solution provided by this invention is:

[0026] Example 1

[0027] Please refer to Figures 1-4This embodiment describes a rainwater filtration and recycling device for under-bridge spaces, installed at the bottom of the bridge to collect rainwater seeping in for subsequent use. The rainwater filtration and recycling device includes a rainwater recycling component, which collects the rainwater seeping into the bridge for reuse. The rainwater recycling component includes a funnel 2, which is funnel-shaped and effectively collects rainwater seeping from gaps inside the bridge. In this embodiment, the funnel 2 can be made of a high-strength, corrosion-resistant metal material such as stainless steel, as needed. A conduit 3 connects the conduit 3 to the funnel 2. The bottom connection of the conduit 3 and the bottom connection of the funnel 2 can be either detachable or fixed as needed. The filter bucket 6 is located directly below the bottom of the conduit 3. The function of the conduit 3 is to guide the rainwater collected by the funnel 2 into the filter bucket 6 for filtration. In this embodiment, the shape of the conduit 3 is not limited and can be customized according to the relative positions of the funnel 2 and the filter bucket 6 to achieve the desired rainwater drainage effect. To prevent the rainwater collected by the funnel 2 from flowing directly from the conduit 3 into the filter bucket 6 and causing direct impact on the filter bucket 6, the following measures are taken: To extend the lifespan of the equipment and even affect its overall structural stability, the middle section of the two ends of the conduit 3 can be designed as a transition zone with a certain angle. This buffers the rainwater during the drainage process, preventing the rainwater collected in the funnel 2 from flowing directly from the conduit 3 into the filter hopper 6 and directly impacting it. The conduit 3 and filter hopper 6 can be made of plastic or metal materials with good sealing and corrosion resistance, such as stainless steel or polytetrafluoroethylene, as needed. The filter screen 8, located inside the filter hopper 6, filters the rainwater, removing impurities and contaminants to ensure the quality of the stored rainwater. The water storage tank 11 is used to store filtered rainwater for later use. In this embodiment, the water storage tank 11 can be made of materials with good flexibility and sealing properties, such as rubber or plastic, as needed. The water storage tank 11 is provided with a water outlet on its outside. The water outlet includes a water outlet pipe 13 and a valve 14. The valve 14 is set on the water outlet pipe 13. The function of the valve 14 is to control the opening and closing of the water outlet pipe 13 and to adjust the water flow. The water outlet pipe 13 is used to draw out the rainwater in the water storage tank 11. Passersby can turn on the valve 14 to wash their hands or clean other objects.In this embodiment, the outlet pipe 13 can be made of plastic or metal materials with good sealing and corrosion resistance, and the valve 14 can be made of metal materials such as stainless steel with good sealing and control performance, as needed. The water supply pipe 10 is connected at one end to the filter bucket 6 and at the other end to the water storage tank 11. The function of the water supply pipe 10 is to guide the rainwater filtered by the filter screen 8 in the filter bucket 6 into the water storage tank 11 for storage. In this embodiment, a flexible hose with good flexibility and sealing made of rubber or plastic materials can be selected as the water supply pipe 10 to ensure a more stable and reliable rainwater transmission process.

[0028] As a preferred embodiment, a disassembly and assembly assembly is also included. This assembly is located on the outside of the filter hopper 6 of the rainwater harvesting assembly. In this embodiment, the disassembly and assembly assembly enables the installation and disassembly of the equipment on the bridge. The assembly includes two sliders 17, which are located on the outer sides of the filter hopper 6. The sliders 17 can be made of metal materials such as stainless steel that meet the requirements for strength and wear resistance. Mounting blocks 15 correspond to the sliders 17 on the outer sides of the filter hopper 6. Each mounting block 15 has a guide post 16 that cooperates with each slider 17. Each slider 17 can be slidably mounted on the corresponding guide post 16 to ensure the integrity of the equipment. To ensure the stability of the filter hopper 6, the mounting block 15 can be fixedly connected to the bridge. The mounting block 15 can be made of metal materials such as stainless steel that meet the strength and stability requirements. The mounting block 15 provides the installation position for the guide column 16, and the guide column 16 can guide the sliding of the slider 17, making the installation and disassembly of the filter hopper 6 more convenient, quick and reliable. The guide column 16 can be made of metal materials such as stainless steel that meet the strength and stability requirements. In this embodiment, there is no limit to the number of sliders 17. According to the required overall structural strength and stability, a corresponding number of sliders 17 can be set on the outer sides of the filter hopper 6, and a corresponding number of guide columns 16 can be set to cooperate with the sliders 17.

[0029] In a preferred embodiment, each guide post 16 is fitted with a spring support 18. One end of each spring support 18 abuts against the upper part of the mounting block 15, and the other end abuts against the lower part of the slider 17. The spring support 18 is a spring, which has a certain elasticity and restoring force. It can provide an upward elastic force when the filter hopper 6 is installed, so that the filter hopper 6 fits tightly against the bottom of the conduit 3, ensuring that rainwater can flow smoothly into the filter hopper 6.

[0030] In a preferred embodiment, the outer surface of one end of the conduit 3 located inside the filter hopper 6 abuts against the inner surface of the filter hopper 6, and the outer side of the bottom end of the conduit 3 fits against the inner side of the filter hopper 6, ensuring that rainwater can flow smoothly from the conduit 3 into the filter hopper 6.

[0031] In a preferred embodiment, the top of the water storage tank 11 is provided with a water inlet 12. The function of the water inlet 12 is to facilitate the extraction of rainwater from the water storage tank 11 when needed. It can be connected to a water pump or other pumping equipment for pumping operations. It also includes a pumping pipe (not shown in the figure), which is connected to the water inlet 12 of the water storage tank 11. The end of the pumping pipe near the water inlet 12 of the water storage tank 11 extends towards the bottom wall of the water storage tank 11 and is laid inside the water storage tank 11 to ensure that rainwater at the bottom of the water storage tank 11 can be extracted and to avoid rainwater residue. A water pump is installed inside the water storage tank 11 to connect to the pipe at the water inlet 12. Environmental protection workers can also insert an external pipe into the water inlet 12 and use the water inside the water storage tank 11 to water the surrounding green plants. This not only solves the problem of water leakage at the bottom of the bridge, but also allows the leaked water to be recycled and reused, realizing the recycling of water resources, which has important environmental protection significance.

[0032] In a preferred embodiment, the filter hopper 6 is provided with two support blocks 7, which are located on opposite sides of the filter hopper 6. The filter screen 8 is placed on the support blocks 7 inside the filter hopper 6. The support blocks 7 support the filter screen 8 and ensure that the filter screen 8 is stably positioned inside the filter hopper 6. In this embodiment, the support blocks 7 can be made of metal materials such as stainless steel that can meet the requirements of strength and stability. The number and thickness of the support blocks 7 can be set according to the required support strength.

[0033] In a preferred embodiment, the filter screen 8 is provided with a pull ring 9, which is located on the side away from the bottom of the filter hopper 6. The function of the pull ring 9 is to facilitate the operator to grasp the filter screen 8 for disassembly and installation. The pull ring 9 can be made of metal materials such as stainless steel that can meet the requirements of strength and wear resistance, as needed.

[0034] In this embodiment, when cleaning or replacing the filter screen 8 is required, it can be separated from the guide tube 3 by pressing down on the filter hopper 6 to compress the spring support 18. The operation is simple and convenient. Then, the filter screen 8 can be pulled out from the inside of the filter hopper 6 by grasping the pull ring 9. The design of the pull ring 9 makes the disassembly of the filter screen 8 more convenient. The operator can easily remove the filter screen 8 from the filter hopper 6, thus easily removing and cleaning the filter screen 8 or replacing it directly. This ensures the long-term use of the overall structure. Regularly cleaning or replacing the filter screen 8 can also ensure the filtration effect of the rainwater filtration and recovery equipment and extend the service life of the equipment.

[0035] Example 2

[0036] This embodiment describes a bridge, which includes a rainwater filtration and recycling device based on the space under the bridge as described in Embodiment 1. The bridge includes a bridge structure and support columns 5. The support columns 5 are located at the bottom of the bridge. The bridge is constructed of strong materials such as reinforced concrete, possessing high strength and stability, and capable of bearing the weight of vehicles and pedestrians. The bridge plays an important connecting role in the transportation system. The function of the support columns 5 is to provide support for the bridge, ensuring its stability and safety. The support columns 5 are made of high-strength steel or concrete, possessing good load-bearing capacity. The rainwater filtration and recycling device is installed at the bottom of the bridge. Specifically, the funnel 2 is installed at the bottom of the bridge, and the conduit... The lower part of the 3 is arranged along the support column 5. When installing the equipment, the mounting block 15 is fixedly installed on the support column 5, and then the filter bucket 6 is installed. The water storage tank 11 can be directly fixed or detachably installed on the support column 5 as needed. It also includes multiple fixing parts 4. Each fixing part 4 is clamped on the guide tube 3 and connected to the side wall of the support column 5. Each fixing part 4 is a "U" shaped fixing clamp. One side of the guide tube 3 is attached to one side of the support column 5. The fixing parts 4 can firmly clamp the guide tube 3 on the support column 5 to prevent the guide tube 3 from shaking or shifting during use. In this embodiment, the fixing parts 4 can be made of metal materials with certain strength and stability, such as stainless steel, as needed.

[0037] The working principle of this embodiment is as follows: During rainy days, water inevitably accumulates on the top of the bridge body 1 and seeps through the internal gaps of the bridge body 1 to the bottom of the bridge body 1. A funnel 2 is installed at the corresponding position to collect the water, which then flows through the conduit 3 into the filter hopper 6, and after being filtered by the filter screen 8, it flows through the water supply pipe 10 into the water storage tank 11 for storage. Passersby can turn on the valve 14 and use the water flowing from the outlet pipe 13 to wash their hands or clean other objects. A water pump is installed inside the water storage tank 11 to connect to the pipe at the water inlet 12. Environmental protection workers can also insert an external pipe into the water inlet 12 and use the water inside the water storage tank 11 to spray water on the surrounding green plants. This solves the problem of water leakage at the bottom of the bridge and also allows the leaked water to be recycled.

[0038] Alternatively, the filter hopper 6 can be pressed down to separate it from the bottom of the guide tube 3. Then, the pull ring 9 can be grabbed to pull the filter screen 88 out of the filter hopper 6. This makes it easy to remove and clean the filter screen 8, or replace it directly, ensuring the long-term use of the overall structure.

[0039] 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.
