Description

Technical Field

[0001] This utility model relates to the field of intelligent manhole cover technology, and in particular to an urban pipeline manhole cover device. Background Technology

[0002] With the development of smart manhole covers in urban pipeline networks, various types of smart manhole covers have been widely used. However, these products still have some problems in practical use. For example, although smart manhole covers on the market currently have certain intelligent monitoring and alarm functions, they are still insufficient in some key performance aspects. In order to improve performance, some manufacturers have tried to improve the level of intelligence by adding more sensors and data processing units, but such improvements often face problems such as high system complexity, high maintenance costs, and low data processing efficiency, specifically:

[0003] 1) A smart manhole cover for municipal pipelines, patent number CN113957929B, published on April 28, 2023. This solution provides a smart manhole cover for municipal pipelines, including a manhole cover, a data processing unit, and a sensor unit. The sensor unit is located below the manhole cover and is used to detect the status of the manhole cover or the underground environment. The data processing unit is used to receive and process the data collected by the sensor unit. Although this design can monitor the status of the manhole cover and the underground environment, its data processing and transmission methods are relatively simple, lacking advanced data analysis and processing capabilities, and unable to achieve accurate monitoring and real-time response to complex working conditions. In addition, the sensor unit in this design is relatively simple and cannot comprehensively monitor various states of the manhole cover and environmental factors, thus having certain limitations.

[0004] 2) A pressure spring signal switch for an intelligent urban sewer network manhole cover system, patent number CN108802827B, published on April 21, 2020. This solution discloses an intelligent pressure spring signal switch for an urban sewer network manhole cover system, solving the problem that manual inspection is required to detect lost or damaged covers or during maintenance of detection equipment. This design, through the setting of a pressure switch and probe group, achieves rapid and accurate detection of the cover's condition, improving maintenance efficiency. However, this design mainly relies on the mechanical structure of the pressure switch, resulting in a certain failure rate and false alarm rate. Furthermore, it cannot achieve comprehensive monitoring of the underground environment, such as gas concentration and temperature, and its function is relatively limited, making it difficult to meet the requirements of modern urban pipe networks for intelligent and multifunctional manhole covers.

[0005] The aforementioned issues indicate that while current smart manhole covers on the market possess certain intelligent functions, their ability to accurately monitor and respond in real-time under complex working conditions remains insufficient. Therefore, there is an urgent need to provide a technical solution to address these problems. Utility Model Content

Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0035] Figure 1 A schematic diagram of an embodiment of an urban pipeline manhole cover device provided by this utility model is shown. Figure 1 As shown, the urban pipeline manhole cover device includes: manhole cover body 1, data processing unit 2, composite sensor array 3, intelligent opening and closing mechanism 4, and Internet of Things communication module 5.

[0036] The manhole cover body 1 is a common type of manhole cover on the market. It typically consists of two parts: a cover plate and a frame. The cover plate is the upper surface of the manhole cover and is used to withstand external pressure; the frame is the supporting structure of the cover plate, used to fix the cover plate and prevent it from moving. In this embodiment, a circular manhole cover body 1 is used by default. Since the manhole cover body 1 is a common device on the market, only a schematic diagram of the manhole cover body 1 is provided for illustration in this embodiment. The data processing unit 2 is defaulted to a DPU (Data Processing Unit). In this embodiment, an NVIDIA BlueField DPU is specifically used, but it can be adjusted according to actual conditions, and no restrictions are set here. The IoT communication module 5 defaults to an ESP8266 or ESP32 model, but it can also be adjusted according to actual conditions, and no restrictions are set here.

[0037] The manhole cover body 1 is circular and has a mounting hole 11 in the middle. The mounting hole 11 is used to install the data processing unit 2 and the composite sensor array 3.

[0038] The mounting hole 11 adopts a variable diameter structure, and the default is a stepped mounting hole. The data processing unit 2 is fixedly installed on the upper layer of the stepped mounting hole, and the composite sensor array 3 is fixedly installed on the lower layer of the stepped mounting hole (the layer adjacent to the data processing unit 2). That is, multiple sensors in the composite sensor array 3 are distributed around the lower layer of the stepped mounting hole.

[0039] The data processing unit 2 is fixedly installed in the middle of the lower surface of the manhole cover body 1. The lower surface of the data processing unit 2 is provided with multiple sensor interfaces 21, which are connected to the composite sensor array 3 through the multiple sensor interfaces 21.

[0044] The IoT communication module 5 is installed on the top of the data processing unit 2, and the IoT communication module 5 is electrically connected to the data processing unit 2.

[0045] Among them, the IoT communication module 5 establishes a two-way data channel with the data processing unit 2.

[0046] It should be noted that, Figure 1 The structural schematic diagram of the urban pipeline manhole cover device shown can be understood as an exploded view of the device. Figure 1 The data processing unit 2, composite sensor array 3, intelligent opening and closing mechanism 4, IoT communication module 5, mounting hole 11, and sensor interface 21 are all common device structures on the market, and there is no improvement on a single structure. Therefore, the above device structure has been modularized, which can more intuitively and clearly reflect the innovation of the urban pipeline manhole cover device. In addition, the specific connection relationship and position relationship have been described in detail in this embodiment. Figure 2 As shown, Figure 2 The structural block diagram concisely and clearly describes the connection relationship and communication logic of the urban pipeline manhole cover device.

[0047] In one alternative embodiment, the intelligent opening and closing mechanism 4 includes a motor, a transmission device, and a linkage rod.

[0048] The motor is fixedly mounted on the upper edge of the manhole cover body 1, the transmission device is fixed to the output shaft of the motor, one end of the linkage rod is connected to the transmission device, and the other end of the linkage rod is connected to the opening and closing mechanism of the manhole cover body 1. The motor drives the linkage rod through the transmission device, enabling the manhole cover body 1 to open and close automatically.

[0049] It should be noted that after receiving the remote command, the data processing unit 2 generates a control command for the motor and sends it to the motor. This allows the motor to drive the linkage rod via a transmission device, enabling the manhole cover body 1 to open and close automatically. The specific principle of the drive control is existing technology and will not be elaborated upon here.

[0050] In one alternative embodiment, the intelligent opening and closing mechanism 4 further includes a backup power supply; the backup power supply is connected to the motor.

[0051] The backup power supply is used to ensure the safe opening and closing of the manhole cover body 1 in the event of a power outage or failure of the main battery, thus improving safety performance.

[0052] In one alternative embodiment, the IoT communication module 5 includes: a wireless communication module; the wireless communication module is fixedly installed on the top of the data processing unit 2, the wireless communication module is connected to the data processing unit 2 through a waterproof interface, and the wireless communication module is also connected to a remote management platform.

[0053] The wireless communication module is used to enable remote data transmission.

[0054] In one alternative embodiment, the plurality of sensors include: a temperature sensor, a humidity sensor, a gas concentration sensor, a pressure sensor, a vibration sensor, and an image sensor.

[0055] The temperature sensor, humidity sensor, and gas concentration sensor are respectively installed in different quadrants of the four quadrants on the lower surface of the manhole cover body 1, with one sensor installed in each quadrant to achieve comprehensive monitoring of the underground environment. The pressure sensor is installed at the center of the lower surface of the manhole cover body 1, the vibration sensor is installed at the edge of the lower surface of the manhole cover body 1, and the image sensor is installed at the bottom center of the lower surface of the manhole cover body 1. The pressure sensor is used to detect pressure changes in the manhole cover body 1. The vibration sensor is used to detect vibration of the manhole cover body 1. The image sensor is used to capture images of the underground environment.

[0056] In one alternative, the motor and the transmission device are enclosed in a sealed housing to prevent the effects of downhole moisture and dust.

[0057] In one alternative embodiment, the data processing unit 2 includes a central processing unit, a storage module, and a power management module.

[0058] The central processing unit (CPU) processes data from the composite sensor array 3, the storage module stores the data, and the power management module manages the power supply to the power module. The CPU connects to the multiple sensors via the multiple sensor interfaces 21 and communicates with the remote management platform via the wireless communication module.

[0059] In one alternative embodiment, the lower surface of the manhole cover body 1 is provided with a waterproof coating made of a corrosion-resistant material to prevent erosion by moisture and chemicals in the manhole.

[0060] In one alternative embodiment, the edge of the manhole cover body 1 is provided with a sealing ring to enhance the sealing performance of the manhole cover body 1.

[0061] In one alternative embodiment, the system further includes a solar panel and a power module; the solar panel is fixedly installed on the upper surface of the manhole cover body 1, and the solar panel is connected to the power module via wires.

[0062] The solar panels provide additional power to the entire device, and are protected by a transparent protective cover.

[0063] It should be noted that the above design scheme has achieved significant results in improving the performance of existing smart manhole covers, solving the problem of how to achieve comprehensive, real-time, and accurate perception of the underground conditions in complex environments, and realizing the following functional advantages:

[0064] On the one hand, by installing a diverse composite sensor array 3, comprehensive data collection on underground temperature, humidity, gas content (including hazardous gases), liquid level, vibration, and local real-time imaging is achieved. This not only improves information coverage and resolution but also provides the possibility of understanding the site conditions from multiple angles, allowing for complete control over the operation of underground pipelines. This enables faster detection of abnormal signals, allowing for early warning and preventative measures to reduce potential damage. On the other hand, a high-performance microcomputer chip (data processing unit 2) is introduced as a computing platform, combined with advanced communication technology to construct an efficient distributed processing and transmission link system. This ensures that the acquired raw observation records are processed and transformed into usable intelligence in real time, and then quickly delivered to operation and maintenance management personnel to guide decision-making in practice. This greatly enhances the response speed, adaptability, and intelligence of the entire monitoring and management system. The improved manhole cover device in this embodiment not only meets the requirements of modern urban construction planning but also provides citizens with more safe and reliable facility guarantees.

[0065] In actual operation, when this device is in use, the manhole cover remains installed in the designated location within the urban pipe network. Multiple sensors in the composite sensor array 3 collect real-time environmental data around the manhole cover, including temperature, humidity, gas concentration, pressure, vibration, and image information. This sensor data is integrated and analyzed by the data processing unit 2. The intelligent opening and closing mechanism 4 executes the opening or closing operation of the manhole cover according to the instructions issued by the data processing unit 2. Specifically, a motor drives a linkage rod via a transmission device to control the movement of the manhole cover. The IoT communication module 5 sends the processed data to the remote management platform and receives control instructions from the remote management platform. Simultaneously, a backup power supply ensures that the motor can still operate normally in the event of a main power failure. Solar panels provide supplementary power, supplying power to the entire device through the power module to ensure the continuous and stable operation of the system. Furthermore, the waterproof coating and sealing ring of the manhole cover body 1 prevent external environmental factors from affecting the internal structure of the equipment, ensuring long-term reliable use.

[0066] The technical solution of this embodiment integrates multiple sensors to achieve comprehensive monitoring of the manhole cover status and the underground environment, thereby improving the intelligence level of the manhole cover; through the intelligent opening and closing mechanism, the manhole cover is automatically opened and closed, improving the maintenance efficiency and safety of the manhole cover; through the Internet of Things communication module, real-time data transmission and remote management are realized, improving the management efficiency and reliability of the manhole cover.
