Description

Technical Field

[0001] This utility model relates to the field of building and bridge technology, specifically to a rainwater harvesting device for bridges. Background Technology

[0002] Bridges are structures that allow vehicles and pedestrians to pass smoothly. With the rapid development of the modern transportation industry, their functions have been further extended. They can also be used to cross mountain streams and areas with poor geological conditions, or to meet other transportation needs, in order to improve the convenience of passage.

[0003] A search revealed that a utility model patent with publication number CN210737675U discloses a rainwater recycling device for building bridges, including a bridge body, a connecting column fixedly connected to the lower end of the bridge body, a water storage tank fixedly connected to the lower end of the connecting column, a water spray nozzle fixedly connected to the lower end of the water storage tank, a water inlet channel opened inside the bridge body, a filter screen fixedly connected to the bottom end of the water inlet channel, and a slag outlet opened on the inner wall of the bottom end of the water inlet channel.

[0004] This patent achieves the collection and recycling of rainwater from bridges through a water storage tank, but it has limitations in the water usage process. Water can only flow out from the bottom of the tank. In actual bridge construction, green plants are usually planted at equal intervals on both sides of the bridge railings. To meet the irrigation needs of the green plants, additional water pipes, pumps and other equipment need to be connected to the device. This not only takes a lot of time to install the water pipes and pumps, but also increases manpower. Furthermore, the water pipe laying process may affect other bridge facilities and damage the overall aesthetics of the bridge. Utility Model Content

[0005] The purpose of this invention is to provide a rainwater harvesting device for bridges to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rainwater harvesting device for bridges, comprising a bridge body, support columns fixedly connected at equal intervals to the bottom of the bridge body, and a water storage tank fixedly connected to the bottom of the support columns. A drainage channel is equidistantly opened through the surface of the bridge body, with a metal filter screen embedded at the inlet of the drainage channel. The outlet of the drainage channel extends to the bottom of the bridge body. A drainage component is installed on the side of the water storage tank, with its input end connected to the interior of the water storage tank. A water pump is fixedly installed inside the water storage tank, with a water pipe fixedly connected to the output end of the water pump. A water outlet pipe is fixedly connected to the output end of the water pipe. Self-sealing irrigation expansion joints are equidistantly installed on the surface of the water outlet pipe, with their input end connected to the interior of the water outlet pipe.

[0007] Preferably, the self-sealing irrigation telescopic assembly includes a fixed sleeve fitted onto the outer surface of the outlet pipe. The outer surface of the outlet pipe has water holes inside the fixed sleeve, and the interior of the outlet pipe communicates with the interior of the fixed sleeve. An outer tube communicating with the interior of the fixed sleeve is fixedly connected to the top of the fixed sleeve. A groove is formed inside the outer tube, with the top diameter of the groove being smaller than the bottom diameter. Positioning plates are fixedly connected at equal intervals to the inner wall of the groove. A sealing plate is longitudinally and slidably connected to the interior of the groove. A support cylinder is fixedly connected to the top center of the sealing plate. Limiting plates are fixedly connected at equal intervals to the outer surface of the support cylinder. An arc-shaped groove matching the limiting plate is formed on the small-diameter inner wall of the top of the groove. A water nozzle communicating with the interior of the support cylinder is embedded in the surface of the support cylinder. A sealing block is fixedly connected to the top of the support cylinder. The interior of the fixed sleeve communicates with the sealing plate and the interior of the support cylinder. A spring is movably fitted onto the outer surface of the support cylinder.

[0008] Preferably, the surface of the limiting plate is arc-shaped, and a sealing ring is fixedly installed on the outer surface of the sealing plate.

[0009] Preferably, under normal conditions, the elasticity of the spring causes the sealing plate to slide downwards, driving the support cylinder and the sealing block. At this time, the surface of the sealing block is sealed and adhered to the upper surface of the outer tube. The sealing block is a silicone plate.

[0010] Preferably, a photovoltaic panel and a control cabinet are fixedly installed on the outer surface of the water storage tank. The control cabinet contains a battery for storing electricity in the photovoltaic panel and a timer controller for controlling the water pump to start and stop at specific times.

[0011] Preferably, the drainage component includes a groove formed on the side of the water storage tank, a water passage groove formed on the side wall of the groove, a fixing box fixedly connected to the side of the water storage tank, a drain pipe fixedly connected to the bottom of the fixing box, and the interior of the water storage tank is connected to the interior of the drain pipe through the water passage groove, the groove, the fixing box, and the drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model's rainwater harvesting structure eliminates the need for additional water pipes. The device's built-in outlet pipe and self-sealing irrigation telescopic component directly match the irrigation needs of the greenery on both sides of the bridge, saving the steps of connecting additional equipment as in traditional devices, reducing installation time and construction costs. Relying on photovoltaic power supply and a timer controller, it can automatically complete rainwater extraction and irrigation operations without manual operation, reducing labor input and avoiding water waste or equipment damage caused by human error. The automatic telescopic design of the self-sealing irrigation telescopic component extends the water nozzle to spray water during irrigation and automatically retracts when not in use, eliminating the need for manual disassembly or obstruction, further simplifying daily maintenance procedures. The drainage component in this utility model can drain rainwater according to a planned path through a water channel and drainage pipe before the water storage tank overflows, preventing rainwater from dripping randomly onto pedestrians and buildings under the bridge, eliminating safety hazards. When not in use, the water nozzle and support cylinder are stored in a sliding groove, and the entire structure is located below the bridge's horizontal plane, without damaging the original appearance design of the bridge, solving the problem of traditional exposed water pipes affecting aesthetics.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Please see Figure 1-5As shown, a rainwater harvesting device for bridges includes a bridge body 1, support columns 3 fixedly connected at equal intervals to the bottom of the bridge body 1, and a water storage tank 4 fixedly connected to the bottom of the support columns 3. A drainage channel 2 is provided through the surface of the bridge body 1 at equal intervals. A metal filter screen is embedded at the inlet of the drainage channel 2, and the outlet of the drainage channel 2 extends to the bottom of the bridge body. A drainage component 5 is installed on the side of the water storage tank 4. The input end of the drainage component 5 is connected to the interior of the water storage tank 4. A water pump is fixedly installed inside the water storage tank 4. A water pipe 6 is fixedly connected to the output end of the water pump. A water outlet pipe 7 is fixedly connected to the output end of the water pipe 6. Self-sealing irrigation expansion components 8 are installed at equal intervals on the surface of the water outlet pipe 7. The input end of the self-sealing irrigation expansion components 8 is connected to the interior of the water outlet pipe 7.

[0017] In this implementation scheme, the drain trough 2 can quickly guide rainwater to the water storage tank 4 to achieve efficient rainwater collection. The metal filter screen can filter impurities in the rainwater to prevent impurities from entering the water storage tank 4 and causing internal blockage, thus ensuring the normal operation of subsequent equipment such as water pumps.

[0018] The water storage tank 4 is fixed to the bottom of the bridge body 1 by the support column 3, which does not require additional ground space and saves installation space; the combination of water pump, water pipe 6, water outlet pipe 7 and self-sealing irrigation expansion component 8 directly provides water for the irrigation of bridge green plants, without the need to lay additional water pipes, reducing installation steps and costs.

[0019] Specifically, the self-sealing irrigation telescopic assembly 8 includes a fixed sleeve 81 fitted onto the outer surface of the outlet pipe 7. Water holes are formed inside the fixed sleeve 81 on the outer surface of the outlet pipe 7, and the interior of the outlet pipe 7 communicates with the interior of the fixed sleeve 81. An outer pipe 82, communicating with the interior of the fixed sleeve 81, is fixedly connected to the top of the fixed sleeve 81. A groove 83 is formed inside the outer pipe 82, with the top diameter of the groove 83 smaller than its bottom diameter. Positioning plates 84 are fixedly connected at equal intervals to the inner wall of the groove 83. The groove 83 has a longitudinally sealed sliding connection. A sealing plate 85 is attached, and a support cylinder 86 is fixedly connected to the top center of the sealing plate 85. Limiting plates 87 are fixedly connected at equal intervals to the outer surface of the support cylinder 86. An arc-shaped groove matching the limiting plate 87 is opened on the small-diameter inner wall of the top of the slide groove 83. A water spray head 88 communicating with the inside of the support cylinder 86 is embedded in the surface of the support cylinder 86. A sealing block 89 is fixedly connected to the top of the support cylinder 86. The inside of the fixing sleeve 81 is connected to the inside of the sealing plate 85 and the support cylinder 86. A spring 810 is movably sleeved on the outer surface of the support cylinder 86.

[0020] In this embodiment, the connection between the fixed sleeve 81 and the water outlet pipe 7, combined with the water holes on the water outlet pipe 7, allows water to flow steadily into the fixed sleeve 81 and then to the outer pipe 82, ensuring smooth water flow. The design of the top diameter of the slide groove 83 being smaller than the bottom diameter, together with the positioning plate 84, can limit the sliding of the sealing plate 85 and prevent the sealing plate 85 from sliding excessively and detaching from the slide groove 83.

[0021] The limiting plate 87 on the support cylinder 86 and the arc-shaped groove at the top of the slide 83 can maintain stability and prevent shaking when the support cylinder 86 is extended or retracted; the water nozzle 88 is embedded in the support cylinder 86 and communicates with the interior, which can accurately spray water to the green plants and improve irrigation efficiency; the sealing block 89 cooperates with the spring 810 to seal the top of the outer tube 82 when idle, preventing dust and debris from entering the interior of the slide 83 and protecting the internal structure of the component.

[0022] Specifically, the surface of the limiting plate 87 is arc-shaped, and a sealing ring is fixedly installed on the outer surface of the sealing plate 85.

[0023] In this embodiment, the surface of the limiting plate 87 is arc-shaped, which can reduce friction with the inner wall of the slide groove 83 during the sliding process of the support cylinder 86, reduce component wear, and extend the service life of the limiting plate 87.

[0024] The sealing ring on the outer surface of the sealing plate 85 can enhance the sealing performance between the sealing plate 85 and the inner wall of the slide groove 83, prevent water from leaking out from the gap between the sealing plate 85 and the slide groove 83, ensure stable water pressure, and ensure that the water nozzle 88 sprays water normally.

[0025] Specifically, under normal conditions, the elasticity of the spring 810 causes the sealing plate 85 to slide downwards, driving the support cylinder 86 and the sealing block 89. At this time, the surface of the sealing block 89 is sealed and adhered to the upper surface of the outer tube 82. The sealing block 89 is a silicone plate.

[0026] In this implementation scheme, under normal conditions, the elasticity of the spring 810 causes the sealing plate 85, the support cylinder 86 and the sealing block 89 to slide down, so that the sealing block 89 seals the top of the outer tube 82, which can effectively prevent external debris from entering the self-sealing irrigation telescopic component 8, reduce the probability of component failure and reduce the maintenance frequency.

[0027] The sealing block 89 is made of silicone plate material. Silicone has good elasticity and sealing properties, which can fit tightly to the top of the outer tube 82 and improve the sealing effect. At the same time, silicone material is resistant to aging and can maintain sealing performance for a long time, extending the replacement cycle of sealing block 89.

[0028] Specifically, a photovoltaic panel and a control cabinet are fixedly installed on the outer surface of the water storage tank 4. The control cabinet contains a battery for storing electricity in the photovoltaic panel and a timer controller for controlling the water pump to start and stop at specific times.

[0029] In this implementation plan, photovoltaic panels can convert solar energy into electrical energy to charge batteries, thereby achieving sustainable energy use, reducing dependence on traditional power grids, and lowering the energy costs of operating the device.

[0030] The battery in the control cabinet can store the electrical energy converted by the photovoltaic panel, ensuring that the device can still operate normally during periods without sunlight (such as cloudy days and nights); the timer controller can control the water pump to start and stop at set times, realizing the automation of rainwater extraction and irrigation without the need for manual operation, reducing manpower input, and avoiding water waste or equipment damage caused by improper manual operation.

[0031] Specifically, the drainage component 5 includes a groove 51 formed on the side of the water storage tank 4, a water passage groove 52 formed on the side wall of the groove 51, a fixing box 53 fixedly connected to the side of the water storage tank 4, and a drain pipe 54 fixedly connected to the bottom of the fixing box 53. The interior of the water storage tank 4 is connected to the interior of the drain pipe 54 through the water passage groove 52, the groove 51, the fixing box 53.

[0032] In this implementation plan, when there is too much rainwater in the water storage tank 4, the rainwater can enter the groove 51 through the water channel 52, and then flow to the drain pipe 54 through the fixing box 53, draining according to the planned path, so as to prevent rainwater from overflowing from the top of the water storage tank 4 and dripping down to the bridge, thus preventing safety hazards to pedestrians below and also preventing rainwater from damaging the buildings below the bridge.

[0033] The drainage component 5 has a simple structural design and is integrated into the side of the water storage tank 4, requiring no additional space and making installation convenient. Meanwhile, the directional drainage function of the drainage pipe 54 can guide excess rainwater to appropriate locations (such as ground drainage systems), achieving reasonable discharge and diversion of rainwater and avoiding water waste. Working principle: When it rains, rainwater is directly guided and stored inside the water storage tank 4 through the drainage channel 2. When the water storage tank 4 stores too much rainwater, before the rainwater overflows from the top of the water storage tank 4, it will enter the groove 51 through the water channel 52, and then fall down in a concentrated manner through the drainage pipe 54 according to the planned path, so as to prevent the overflowing water from falling on pedestrians or buildings under the main body of the bridge 1. On sunny days, the photovoltaic panels on the side of the water tank 4 convert solar energy into electrical energy and store it in the battery. When it is necessary to water the plants on both sides of the main body of the bridge 1, the controller turns on the water pump. After turning on, the water inside the water tank 4 enters the outlet pipe 7 through the water pipe 6, and then enters the fixed sleeve 81 through the water hole on the outlet pipe 7. Then, it enters the bottom of the sliding groove 83 through the fixed sleeve 81. Due to the increased water pressure, the sealing plate 85 is forced to slide upward. The sealing plate 85 drives the support cylinder 86 and the sealing block 89 to slide upward. The water nozzle 88 gradually extends out from the sliding groove 83. After the sealing plate 85 slides upward to the designated position, it reaches a stable height. Water pressure passes through the sealing plate 85 and the support cylinder 86, and is sprayed out through the water nozzle 88 to water the plants. When watering is not needed, the water pump is turned off, the water pressure inside the fixing sleeve 81 decreases, and the elasticity of the spring 810 causes the sealing plate 85 to drive the support cylinder 86 to slide downward, storing the support cylinder 86 and the water nozzle 88 inside the slide groove 83. The sealing block 89 seals the top of the slide groove 83, which not only protects the water nozzle 88, but also ensures that the stored support cylinder 86 is located below the horizontal plane of the bridge, without compromising the overall aesthetics of the bridge. The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
