Description

Technical Field

[0001] This invention relates to the field of municipal drainage equipment technology, and in particular to a municipal rainwater drainage device and early warning system. Background Technology

[0002] Municipal drainage systems play a vital role in people's daily lives and various sectors of the national economy. Municipal drainage pipes refer to the rainwater and sewage pipes under municipal roads, commonly known as "sewage pipes." When existing drainage device covers are driven over by vehicles on the road, the lack of flexible buffer devices inside the devices causes a thud, which not only affects the service life of the devices but also impacts driving safety due to the jolting sensation.

[0003] Meanwhile, urban flood control is both a major project for improving people's livelihoods and a major development project. Urban flood control is a systematic and long-term project that requires not only strengthening the inspection and maintenance of urban drainage networks and pumping stations, but also further improving the level of informatization, such as building an information management and control platform for drainage systems, developing urban rainstorm and flood monitoring and early warning systems, and vigorously strengthening the management of urban drainage facilities.

[0004] Currently common drainage systems have fixed, open inlets, making them extremely susceptible to debris such as leaves entering during sunny weather. This can clog drainage wells and impede drainage during rainy days. Fixed inlets also prevent adjustment of drainage capacity based on rainfall volume, resulting in poor adjustability and overall ineffective drainage. This makes them highly prone to causing urban flooding during heavy rains. Furthermore, the lack of effective information technology to support the operation and maintenance of drainage facilities makes it difficult to monitor their operational status in real time, leading to low efficiency in daily maintenance and hindering continuous readiness. Insufficient foresight regarding flooding risks and delayed response, coupled with the large number of drainage wells in cities (often tens of thousands) that are difficult to locate, and the lack of location and navigation systems, prevents maintenance personnel from reaching, adjusting, or clearing drainage wells in a timely and accurate manner. This also contributes significantly to the frequent occurrence of urban flooding. Summary of the Invention

[0005] This invention provides a municipal stormwater drainage device and an early warning system, which at least solves the technical problem of the impact of municipal stormwater drainage devices on driving safety, and further can effectively improve the city's stormwater drainage capacity and reduce the risk of urban flooding.

[0006] To achieve the above-mentioned objectives, this invention provides a municipal rainwater drainage device, comprising an annular fixing ring, the inner edge of which extends downward to form a vertical cylinder, and the outer edge of which extends upward to form a receiving groove wall. The receiving groove wall and the upper surface of the fixing ring form a receiving groove. A plurality of downwardly extending fixing pipes are evenly distributed along the circumference of the fixing ring, each fixing pipe having an upper-opening cavity. A cover plate is provided inside the receiving groove to seal the vertical cylinder. A drainage groove is provided on the cover plate to connect the upper space of the cover plate with the vertical cylinder. A spring rod is provided at the bottom of the cover plate, corresponding to each receiving groove. A plurality of rubber columns, approximately perpendicular to the spring rod, are evenly distributed on the outer surface of the spring rod. The cover plate is installed in the receiving groove, and the spring rods are inserted into the corresponding fixing pipes.

[0007] During construction, the fixing ring, vertical cylinder, and fixing pipe are poured into the concrete ground, and the cover plate and elastic rod are installed inside the fixing ring and fixing pipe. When the wheel runs over the cover plate, kinetic energy is absorbed between the rubber column and the inner wall of the fixing pipe. This creates a slight, soft jerking sensation in the cover plate, which helps to alert fatigued drivers while avoiding the impact of rigid jerking on the locomotive.

[0008] Preferably, the number of fixing tubes is six, and the number of elastic rods is six.

[0009] Preferably, the top of the inner wall of the receiving groove is provided with a rounded chamfer to facilitate the installation of the cover plate.

[0010] Optionally, the bottom of the vertical cylinder is connected to a transfer pipe fitting, which includes a first processing channel extending vertically and a second processing channel extending horizontally, which are interconnected. More preferably, the top of the first processing channel of the transfer pipe fitting is connected to the lower end of the vertical cylinder via a first conversion pipe. More preferably, the end of the second processing channel of the transfer pipe fitting is connected to a second conversion pipe, which is used to connect to a circular sewer pipe. Preferably, both the first and second processing channels have rectangular cross-sections. The rectangular cross-section of the processing channel facilitates the installation of various monitoring components, and all components and equipment are centrally installed inside the processing channel.

[0011] Preferably, the upper surface of the cover plate is provided with a circular groove, and an inner rotating plate is provided in the groove. The inner rotating plate is provided with a traction groove. By rotating the inner rotating plate, the overlapping area of ​​the traction groove of the inner rotating plate and the drainage groove of the cover plate can be adjusted, thereby adjusting the size of the water inlet. On sunny days, the water inlet of the drainage device can be closed or reduced to prevent leaves and other debris from entering. On rainy days, the size of the water inlet of the drainage device can be adjusted according to the amount of rainfall to achieve rapid drainage.

[0012] More preferably, a rotating column is provided at the center of the groove of the cover plate, and a mounting hole that mates with the rotating column is provided at the center of the inner rotating plate. The inner rotating plate is fitted onto the rotating column through the mounting hole, so that the inner rotating plate can rotate around the rotating column. More preferably, the rotating column is a decagonal prism, and the mounting hole is a decagonal opening that mates with the decagonal prism.

[0013] Preferably, a retention box is installed at the bottom of the transfer pipe fitting, and the retention box is located directly below the first processing channel. Further, an opening for installing the retention box is provided on the bottom surface of the transfer pipe fitting, and an extension flange 801 matching the opening is provided at the top of the retention box 8. The extension flange 801 is fixedly connected to the bottom surface of the transfer pipe fitting by bolts.

[0014] A second aspect of the present invention provides an early warning system employing the aforementioned municipal stormwater drainage device, comprising the aforementioned municipal stormwater drainage device, wherein a liquid level monitoring component for detecting the water level within the second processing channel and a video monitoring component for capturing images within the second processing channel are provided in the second processing channel.

[0015] The video monitoring component includes a sealed enclosure made of transparent glass. The sealed enclosure is fixedly connected to the inner wall of the connecting pipe via a sealed flange. A rubber pad is also laid between the sealed flange and the side wall of the second processing channel. A camera is installed in the chamber inside the sealed enclosure, and the camera can transmit the image data of the drainage device back to the central control room.

[0016] The cameras and drainage devices are associated with each other and numbered, and the jurisdiction area is divided into zones according to the drainage system and characteristics. The cameras are connected to the central control room wirelessly. During rainfall, the liquid level monitoring component monitors the liquid level in the drainage device. When the liquid level is abnormal, the image data transmitted from the camera in the drainage device to the large screen in the central control room can be used for verification.

[0017] The review results are divided into two types. The first type does not affect the normal operation of the drainage device and is therefore left unattended. The second type results in the occurrence of blockage or other abnormalities, in which case an operation and maintenance instruction is issued.

[0018] The maintenance instructions are issued through the information system. The maintenance personnel in the corresponding area receive the instructions in real time through a mobile app and use the app's navigation function to quickly and accurately reach the abnormal drainage device point for maintenance, eliminate the danger in time, and ensure that all drainage devices operate normally.

[0019] Working principle: The elastic rod at the bottom of the cover plate is inserted into the corresponding fixed pipe. When the vehicle passes over the cover plate, kinetic energy is absorbed between the rubber column and the inner wall of the fixed pipe, creating a slight, flexible jerking sensation. This gentle jerking helps to alert fatigued drivers while avoiding the impact of rigid jerking on the vehicle. Multiple traction grooves on the inner rotating plate are water inlets. Adjusting the angle of the inner rotating plate causes relative displacement between the traction grooves and the leakage grooves, thus adjusting the size of the water inlets. The rectangular cross-section of the treatment channel facilitates the installation of various monitoring components. All components and equipment are centrally installed inside the treatment channel. As the water flows through the retention tank, debris such as leaves accumulate inside. The retention tank is periodically removed and cleaned manually. The liquid level monitoring component transmits the monitored liquid level data back to the central control room via a wireless network. The camera can simultaneously transmit the image data of the drainage device back to the central control room. When the drainage device experiences blockage or other abnormalities, the central control room promptly issues instructions through the information system. The regional maintenance personnel receive the maintenance instructions in real time through a mobile app and use the app's navigation function to quickly and accurately reach the abnormal point for handling, ensuring the normal operation of all drainage devices.

[0020] One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

[0021] The elastic rod at the bottom of the cover plate is inserted into the corresponding fixed tube. When the vehicle passes over the cover plate, kinetic energy is absorbed between the rubber column and the inner wall of the fixed tube, which can make the cover plate produce a slight soft jerking sensation. The soft jerking sensation can awaken fatigued drivers, while avoiding the impact of rigid jerking on the locomotive.

[0022] On sunny days, the drainage system can be prevented from entering the drainage device by closing or reducing the size of the cover inlet, ensuring smooth drainage. On rainy days, the size of the cover inlet can be flexibly adjusted according to the amount of rainfall to improve the adjustability of drainage capacity.

[0023] The operational status of drainage facilities can be monitored in real time through liquid level monitoring devices and video images, providing support for daily operation and maintenance, and enabling timely warnings and responses. If the video verification results do not affect the normal operation of the drainage device, it can be left unattended. However, if a blockage or other abnormality occurs, maintenance personnel will be dispatched to the drainage device location for maintenance.

[0024] Through the information system, potential hazards can be detected in real time, maintenance instructions can be issued and received quickly, and navigation functions can be used to quickly and accurately reach abnormal drainage points, effectively improving the efficiency of hazard handling and disposal.

On sunny days, the water inlet of the drainage device can be closed or reduced to prevent leaves and other debris from entering. On rainy days, the size of the water inlet of the drainage device can be adjusted according to the amount of rainfall to achieve rapid drainage.

[0039] like Figure 4 As shown, a second aspect of the present invention provides an early warning system using the municipal stormwater drainage device, which includes the municipal stormwater drainage device, wherein a liquid level monitoring component 10 for detecting the water level in the second processing channel and a video monitoring component for capturing images of the second processing channel are provided in the second processing channel.

[0040] The video monitoring component includes a sealed enclosure 11 made of transparent glass. The sealed enclosure 11 is fixedly connected to the inner wall of the connecting pipe 5 via a sealed flange. A rubber pad is also laid between the sealed flange and the side wall of the second processing channel. A camera is installed in the chamber inside the sealed enclosure 11. The camera can transmit the image data of the drainage device back to the central control room.

[0041] The cameras and drainage devices are associated with each other and numbered, and the jurisdiction area is divided into zones according to the drainage system and characteristics. The cameras are connected to the central control room wirelessly. During rainfall, the liquid level monitoring component monitors the liquid level in the drainage device.

The soft jerking sensation has the effect of alerting fatigued drivers, while avoiding the impact of rigid jerking on the locomotive. The multiple traction grooves 301 on the inner rotating plate are water inlets. Adjusting the angle of the inner rotating plate 304 causes the traction grooves 301 to move relative to the water leakage groove, thereby adjusting the size of the water inlet. The rectangular cross-section of the connecting pipe fitting 5 facilitates the installation of various monitoring components. All components and equipment are centrally installed in the... Inside the transfer fitting 5, when water flows through the retention tank 8, debris such as leaves will accumulate inside the retention tank 8. The retention tank 8 is manually removed and cleaned periodically. The liquid level monitoring component transmits the monitored liquid level data back to the central control room via wireless network. The camera can simultaneously transmit the image data of the drainage device back to the central control room.
