Description

Technical Field

[0001] This invention relates to the field of smart city drainage technology, specifically to a flood control device for smart cities. Background Technology

[0002] Today's smart cities refer to the application of intelligent computing technologies such as the Internet of Things, cloud computing, big data, and geospatial information integration in urban planning, design, construction, management, and operation. This makes key infrastructure components and services of cities, such as urban management, education, healthcare, real estate, transportation, public utilities, and public safety, more interconnected, efficient, and intelligent, thereby providing citizens with better living and working services, creating a more favorable business environment for enterprises, and empowering governments with more efficient operation and management mechanisms.

[0003] Urban flooding refers to the phenomenon of water accumulation in cities caused by heavy or continuous rainfall exceeding the city's drainage capacity. The objective causes of flooding are high rainfall intensity and concentrated areas. Areas experiencing particularly heavy rainfall may develop flooding, as may areas with high rainfall intensity and prolonged duration.

[0004] The waterlogging control device is a device that can address drainage problems in smart cities when rainfall is heavy and prolonged.

[0005] In most existing smart cities, drainage screens are used as flood control devices. Depending on the flood season or weather conditions, the drainage screens are opened, usually manually operated by sanitation workers, to expand the drainage outlets and reduce drainage blockage.

[0006] The situation of drainage grates in the city is different. Due to long-term vehicle traffic, the drainage grates on the main roads are often deformed in some areas, causing the drainage grates and manhole covers to get stuck and unable to be opened by themselves. Tools are needed to open them.

[0007] Furthermore, many drainage grates pose significant safety hazards when opened, as opening and closing them requires a certain amount of time, which can easily cause pedestrians or vehicles to slip and fall. They also cannot be adjusted synchronously according to the extent of flooding, making their operation relatively inconsistent. Summary of the Invention

[0008] The purpose of this invention is to provide a flood control device for smart cities to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a flood control device for smart cities, comprising a protective plate, the protective plate including side slots, an inner circular groove, an arc groove, and a central groove; side slots are provided at both ends of the top of the protective plate; an arc groove is provided inside the front side of the protective plate, and an inner circular groove is provided above the arc groove on the same side; a central groove is provided at the bottom of the protective plate; the device further includes a water discharge safety protection mechanism, an automatically reset grid plate assembly, and a water pressure safety monitoring mechanism capable of detecting impact force; the water discharge safety protection mechanism includes a light curtain warning assembly and a diversion baffle assembly; the light curtain warning assembly is equipped with... The inner cavity of the inner circular groove is connected to the outside, and the movable shaft of the diversion baffle assembly is connected to the inner side of the side slot. The automatically reset grid plate assembly is located on the inner side of the arc groove. The automatically reset grid plate assembly includes an arc rod, a filter grid plate and a shock-absorbing spring. The outer wall of the arc rod is arranged with the filter grid plate through it, and the outer wall of the arc rod connected to the filter grid plate is provided with a shock-absorbing spring. The filter grid plate includes a first arc hook and a second arc hook. The filter grid plate is provided with an upwardly protruding first arc hook at one end near the arc groove, and a downwardly protruding second arc hook at the other end of the filter grid plate.

[0010] Furthermore, the protective plate is L-shaped in shape, with symmetrical reinforcing grooves at the top of the short end and symmetrical through grooves at the long end.

[0011] Furthermore, the light curtain warning assembly includes a light curtain emitter and an emitter shaft. The light curtain emitter is snapped into the inner wall of the inner circular groove, and the emitter shaft is axially connected to both ends of the light curtain emitter. The diversion baffle assembly includes a diversion frame shaft, a return spring, and a diversion rod. A diversion rod is welded to one end of the diversion frame shaft near the filter grid plate, and a return spring is sleeved and fixed at the connection point of the diversion frame shaft near the inner wall of the side slot.

[0012] Furthermore, the transmitter shaft and the splitter shaft are arranged in parallel, and synchronous transmission components are installed on the outer walls of the shaft ends of the transmitter shaft and the splitter shaft.

[0013] Furthermore, the diverter shaft is elastically connected to the return spring and the side slot.

[0014] Furthermore, an auxiliary roller is movably installed at the middle of the protective plate, and a belt lifter is provided at the middle of the symmetrical end of the protective plate away from the drainage safety protection mechanism.

[0015] Furthermore, the water pressure safety monitoring mechanism includes a control box, a wireless signal transmission rod, and a retractable monitoring component. The wireless signal transmission rod is arranged on the top of the control box, and the retractable monitoring component is disposed on the inner wall of the middle tank, and the retractable monitoring component is electrically connected to the control box.

[0016] Furthermore, the retractable monitoring component includes a pneumatic rod, a spring rod, a sleeved side movable plate, and a pressure sensor. The spring rod is sleeved at the top of the pneumatic rod, and the sleeved side movable plate is movably sleeved on the outer wall of the spring rod. Pressure sensors are provided at the ends of both sets of sleeved side movable plates and the spring rod.

[0017] Furthermore, the sleeve end of the movable plate with sleeve and the spring rod form an elastic connection.

[0018] Furthermore, the through groove has a larger diameter near the port of the belt hoist and has a trapezoidal cylindrical structure.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The flood control device for smart cities adopts the cooperation between multiple mechanisms, which is highly functional. It uses arc-shaped grid plates. The grid plates will receive different pressures under different water flows, thereby squeezing the elastic components at the side ends to deform and change their own position. The gap between the grid plates is adjusted to adapt to the flood water flow. In conjunction with the light curtain, the flood control points are marked, which improves the safety factor during flood control. The impact force generated by the flood water flow is converted into pressure value, which accurately monitors the local flood situation and facilitates timely adjustment of rescue measures.

[0020] 1. The present invention provides a water discharge safety protection mechanism that combines light curtain protection and barrier protection, and the two protection methods can be used independently or in combination, which can better cope with different water discharge environments;

[0021] The light curtain protection uses a light curtain warning component as its main structure. It projects a light curtain within a specified range through an internal light curtain transmitter, and adjusts the range and position of the side transmitter shaft to ensure that the water leakage point is surrounded and warned.

[0022] The barrier protection uses a diversion block assembly as its main structure, with an internal diversion bar as the main protective structure. Its gate-like structure can directly surround and warn of the water discharge point. In addition, when the water is discharged, the diversion bar will come into contact with the water flow and divert the water flow, thus playing a local buffering role.

[0023] Furthermore, the diverter bar, with its elastic reset structure, can adapt to different water flow heights, preventing the water flow from becoming too deep and reducing the diverter bar's indicator effect, thus increasing safety and reliability.

[0024] 2. The automatic reset grid assembly of the present invention adopts a special arc-shaped distribution, which uses multiple sets of filter grids as basic protective components. The S-hook-shaped structure with inner convex and outer concave can hook other debris while meeting the compressive strength requirements, thus preventing large-area garbage blockage or people from stepping into the gap.

[0025] The connected filter grids are sleeved on the arc rod. The size of the filter grids and the arc grooves are matched to ensure the smooth sliding of the filter grids. The damping springs buffer the filter grids so that they are in a relatively uniform arrangement without the influence of external forces.

[0026] The unique arc-shaped arrangement separates and isolates the water during drainage. As the water is separated, it impacts the filter plates on both sides. As the water flow increases, the impact force becomes stronger, gradually offsetting the elastic restoring force brought by the shock-absorbing springs. This results in an increase in the spacing between the filter plates, making it easier to adjust in real time according to the water flow.

[0027] 3. In this invention, the retractable monitoring component uses a pressure sensor as the sensing element. Compared with other sensors, the pressure sensor has a longer service life and lower cost. It converts the impact force generated during water discharge into pressure acting on the pressure sensor, thereby obtaining relatively accurate water discharge data. Attached Figure Description

[0035] In the description of this invention, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figure 1-6As shown, the present invention provides a technical solution: a flood control device for smart cities, including a protective plate 1. The protective plate 1 includes a side slot 101, an inner circular groove 102, an arc groove 104 and a central groove 105. The top two ends of the protective plate 1 are provided with side slots 101. The front side of the protective plate 1 is provided with an arc groove 104. The inner circular groove 102 is provided above the arc groove 104 on the same side. The bottom of the protective plate 1 is provided with a central groove 105. It also includes a water discharge safety protection mechanism 2, an automatically reset grid plate assembly 3 and a water pressure safety monitoring mechanism 4 that can detect the impact force. The water discharge safety protection mechanism 2 includes a light curtain warning assembly 201 and a diversion baffle assembly 202. The light curtain warning assembly 201 is disposed in the inner cavity of the inner circular groove 102 and is connected to the outside. The diversion baffle assembly 202 is movably connected to the inner side of the side slot 101.

[0038] The light curtain warning assembly 201 includes a light curtain emitter 2011 and an emitter shaft 2012. The light curtain emitter 2011 is snapped into the inner wall of the inner circular groove 102. The emitter shaft 2012 is axially connected to both ends of the light curtain emitter 2011. The diversion baffle assembly 202 includes a diversion frame shaft 2021, a return spring 2022 and a diversion rod 2023. The diversion rod 2023 is welded to one end of the diversion frame shaft 2021 near the filter grid plate 302. The return spring 2022 is sleeved and fixed at the connection point of the diversion frame shaft 2021 near the inner wall of the side slot 101.

[0039] The transmitter shaft 2012 and the splitter shaft 2021 are distributed in parallel, and the outer walls of the shaft ends of the transmitter shaft 2012 and the splitter shaft 2021 are equipped with synchronous transmission components 203.

[0040] The water leakage safety protection mechanism 2 adopts a combination of light curtain protection and barrier protection. The two protection methods can be used independently or in combination, which can better cope with different water leakage environments. By selecting a roller belt drive structure or other synchronous drive structure, the transmitter shaft 2012 and the diverter shaft 2021 are rotated synchronously to realize the combination of light curtain protection and barrier protection.

[0041] The light curtain protection uses the light curtain warning component 201 as the main structure. The light curtain is projected out through the internal light curtain transmitter 2011 and the range position is adjusted with the side transmitter shaft 2012 to ensure that the water leakage point is surrounded and warned. The light curtain warning component 201 can play a good warning role, especially in the case of rainy days when the sky is dim and the light is dim.

[0042] The barrier protection uses the diversion block assembly 202 as the main structure, and the internal diversion rod 2023 as the main protective structure. Its gate-like structure can directly surround and warn the water discharge point. In addition, when the water is discharged, the diversion rod 2023 will come into contact with the water flow and divert the water flow, which plays a local buffering role.

[0043] The diverter shaft 2021 is elastically connected to the side slot 101 via the return spring 2022; furthermore, the diverter rod 2023, through its elastic return structure, can adapt to different water flow heights, preventing the water flow from being too deep, which would reduce the indicator effect of the diverter rod 2023 and increase safety and reliability.

[0044] The self-resetting grid plate assembly 3 is located inside the arc groove 104. The self-resetting grid plate assembly 3 includes an arc rod 301, a filter grid plate 302 and a shock-absorbing spring 303. The outer wall of the arc rod 301 is arranged to pass through the filter grid plate 302, and the outer wall of the arc rod 301 of the adjacent filter grid plate 302 is provided with a shock-absorbing spring 303. The filter grid plate 302 includes a first arc hook portion 3021 and a second arc hook portion 3022. The filter grid plate 302 is provided with an upwardly protruding first arc hook portion 3021 at one end near the arc groove 104, and a downwardly protruding second arc hook portion 3022 at the other end of the filter grid plate 302.

[0045] The self-resetting grid assembly 3 adopts a special arc-shaped distribution, with multiple sets of filter grids 302 arranged to serve as the basic protective component. The S-hook-shaped structure with convex inner and concave outer features can hook other debris while meeting the compressive strength requirements, preventing large-area garbage blockage or people from stepping into the gap.

[0046] The connected filter grid 302 is sleeved on the arc rod 301. The filter grid 302 and the arc groove 104 are fitted together to ensure the smooth sliding of the filter grid 302. The damping spring 303 buffers the filter grid 302 so that it is in a relatively uniform arrangement without the influence of external force.

[0047] The special arc-shaped arrangement will separate and isolate the water during drainage. When the water is separated, it will impact the filter plates 302 on both sides. As the water flow increases, the impact force becomes stronger, gradually offsetting the elastic restoring force brought by the shock-absorbing springs 303. This results in an increase in the spacing of the filter plates 302, which is convenient for real-time adjustment according to the water flow.

[0048] To address the significant safety hazards posed by opening multiple drainage grates, which require a certain amount of time to open and close, potentially causing pedestrians or vehicles to slip and fall.

[0049] The protective plate 1 is L-shaped, and the top of the short end of the protective plate 1 is symmetrically provided with a reinforcing groove 106, and the long end of the protective plate 1 is symmetrically provided with a through groove 103.

[0050] An auxiliary roller 5 is movably installed at the middle of the protective plate 1, and a belt lifter 6 is provided at the middle of the symmetrical end of the protective plate 1 away from the water leakage safety protection mechanism 2.

[0051] For drainage grates deformed by ground pressure, the inner pull strap of the belt lifter 6 can be pulled out, passed through the top of the auxiliary roller 5, and fixed to the opening end of the grates. By pulling the belt lifter 6 and the component force of the auxiliary roller 5, the grates can be lifted out quickly, which will then allow for the installation and fixing of subsequent flood control devices.

[0052] The water pressure safety monitoring mechanism 4 includes a control box 401, a wireless signal transmission rod 402, and a retractable monitoring component 403. The wireless signal transmission rod 402 is arranged on the top of the control box 401, and the retractable monitoring component 403 is located on the inner wall of the middle tank 105. The retractable monitoring component 403 and the control box 401 are electrically connected.

[0053] The retractable monitoring component 403 includes a pneumatic rod 4031, a spring rod 4032, a sleeve-side movable plate 4033, and a pressure sensor 4034. The spring rod 4032 is sleeved on the top of the pneumatic rod 4031, and the sleeve-side movable plate 4033 is movably sleeved on the outer wall of the spring rod 4032. Pressure sensors 4034 are provided at the ends of both sets of sleeve-side movable plates 4033 and spring rods 4032.

[0054] The sleeve end of the sleeve-side movable plate 4033 and the spring rod 4032 form an elastic connection; the retractable monitoring component 403 uses a pressure sensor 4034 as a sensing and monitoring element. Compared with other sensors, the pressure sensor 4034 has a longer service life and lower cost. It converts the impact force generated during water discharge into pressure acting on the pressure sensor 4034, thereby obtaining relatively accurate water discharge data from the side.

[0055] The water discharge data is transmitted to the control box 401. The pressure data can be directly plotted in a table to form a relatively intuitive water flow change, which makes it easier for relevant personnel to analyze the duration of the rainy season based on the water flow changes and adjust the corresponding emergency measures in a timely manner.

[0056] By extending the air rod 4031, the outer spring rod 4032 can be compressed simultaneously, and the sleeve-side movable plate 4033 can be moved outward. When the spring rod 4032 is compressed to its maximum extent, the sleeve-side movable plate 4033 is pushed to a designated position, so that the pressure sensor 4034 on the outer side of the sleeve-side movable plate 4033 is on the same horizontal line as the pressure sensor 4034 at the end of the spring rod 4032, thereby ensuring the accuracy of the sensing and monitoring data.

[0057] The through-channel 103 has a large diameter near the 6th port of the belt hoist and is a trapezoidal cylindrical structure. When water flows behind the flood control device, it can guide the water flow, reduce the impact of the water flow on the device, and ensure the stability and durability of the treatment device.

[0058] In summary, when using this flood control device for smart cities, first place the entire device at the drainage point requiring protection. This can be achieved by pulling out the inner strap of the belt hoist 6, passing it through the top of the auxiliary roller 5, and fixing it to the opening end of the grid plate. The grid plate can then be quickly lifted open by pulling the belt hoist 6 and applying force from the auxiliary roller 5. Next, the entire flood control device is stably placed at one end of the drainage point and secured using the bottom through-hole of the reinforcement groove 106. Weights are added to ensure stability. Then, according to the specifications of the drainage point, the two sides of the light curtain transmitter 2011 are rotated... The emitter shaft 2012 drives the light curtain emitter 2011 to rotate, adjusting the light curtain irradiation range of the light curtain emitter 2011 to match the size of the drainage outlet. Then, the extension of the air rod 4031 is controlled, simultaneously compressing the outer spring rod 4032 and moving the sleeve-side movable plate 4033 outwards. When the spring rod 4032 is at its maximum compression, the sleeve-side movable plate 4033 is pushed to a designated position, causing multiple pressure sensors 4034 to extend outwards. At this time, the filter grid 302 partially extends into the inner side of the drainage outlet, and multiple pressure sensors 4034 extend outwards. The filter plates 302 are arranged in a relatively uniform state under the buffer of the shock-absorbing springs 303. When water is discharged, as the water flow increases, the impact force becomes stronger, gradually offsetting the elastic restoring force brought by the shock-absorbing springs 303, causing the spacing of the filter plates 302 to increase, thereby increasing the discharge port diameter and increasing the drainage volume. At this time, the pressure sensor 4034 at the bottom converts the impact force generated during water discharge into pressure acting on the pressure sensor 4034, obtaining relatively accurate water discharge data from the side, and transmitting the water discharge data to the control box 401, which is then transmitted wirelessly. The transmission rod 402 wirelessly transmits the water discharge data. The pressure data can then be plotted in a table to create a relatively intuitive view of water flow changes. This allows relevant personnel to analyze the duration of the rainy season based on the water flow changes and adjust emergency measures accordingly. As the water flow gradually decreases, the impact force caused by the water flow gradually becomes less than the elastic restoring force provided by the shock-absorbing spring 303. This causes the filter plate 302 to gradually return to its original shape and be evenly arranged again, protecting the water outlet and preventing people from stepping on it. This also gives subsequent personnel enough time to reset the filter plate.

[0059] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
