Description

Technical Field

[0001] This invention relates to the field of municipal infrastructure technology, specifically to a smart lifting manhole cover for municipal use. Background Technology

[0002] Traditional municipal manhole covers are mostly fixed structures, which have many shortcomings in actual use: during heavy rain, water cannot drain quickly, easily causing urban flooding; when manhole covers are stolen, moved, or tilted, there is a lack of real-time monitoring and alarm mechanisms, which can easily lead to safety accidents; manual inspection and maintenance are costly and slow to respond, making it difficult to meet the needs of smart city management. Existing smart manhole covers are mostly based on monitoring functions and lack active adjustment capabilities. They cannot automatically adjust the state of the manhole covers according to environmental changes, making it difficult to balance drainage efficiency and traffic safety. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a municipal intelligent lifting manhole cover. By combining automatic lifting, intelligent monitoring and remote control, the manhole cover status can be monitored and actively adjusted in real time, thereby improving municipal drainage capacity and road traffic safety, and reducing maintenance costs.

[0004] The present invention adopts the following technical solution: A municipal intelligent lifting manhole cover includes a manhole cover body, an automatic lifting device, an intelligent sensing system, an intelligent control module, and a sealing component. The automatic lifting device is connected to the manhole cover body via a transmission mechanism and is used to drive the manhole cover body to achieve lifting and lowering actions. The intelligent sensing system is used to collect data on the manhole cover status and the surrounding environment. The intelligent control module is electrically connected to both the automatic lifting device and the intelligent sensing system and is used to control the lifting and lowering actions according to preset conditions or sensing data. The sealing component is disposed between the manhole cover body and the manhole opening and is used to prevent waterproofing, dustproofing, and foreign object intrusion.

[0005] Furthermore, the automatic lifting device includes a drive motor, a transmission mechanism, and a locking mechanism; the drive motor is electrically connected to the intelligent control module; the transmission mechanism is driven by the drive motor and connected to the manhole cover body, used to convert rotational motion into lifting or flipping motion; the locking mechanism is used to lock the position after the manhole cover is lifted into place to prevent accidental opening or sinking.

[0006] Furthermore, the intelligent sensing system includes a pressure sensor, a tilt sensor, a liquid level sensor, and a communication module; the pressure sensor is used to detect changes in pressure on the surface of the manhole cover; the tilt sensor is used to detect whether the manhole cover is tilted or displaced; the liquid level sensor is used to monitor the water level in the well; and the communication module is used to upload data to the municipal management platform and receive remote control commands.

[0007] Furthermore, the intelligent control module is configured to: automatically raise the manhole cover body to increase drainage capacity when the water accumulation in the well exceeds a preset threshold; trigger an alarm and upload it to the management platform when the manhole cover is detected to be tilted or displaced abnormally; receive remote commands to perform opening, closing or locking operations; and keep the manhole cover locked when a vehicle or pedestrian is detected to ensure traffic safety.

[0008] Furthermore, the sealing assembly includes an elastic sealing ring and a dust cover; the elastic sealing ring is disposed on the contact surface between the manhole cover body and the manhole opening to form a waterproof seal; the dust cover covers the outside of the automatic lifting device and control module to prevent mud and debris from entering.

[0009] Furthermore, the surface of the manhole cover body is provided with an anti-slip mesh structure.

[0010] Furthermore, the transmission mechanism is one or more combinations of lead screw drive, gear and rack drive, or hydraulic lifting mechanism.

[0014] The manhole cover body 1 is made of high-strength ductile iron and has an anti-slip mesh structure on its surface. The automatic lifting device 2 includes a drive motor 21, a screw transmission mechanism 22, and a locking mechanism 23; the drive motor 21 is controlled by the intelligent control module 4 and drives the manhole cover body 1 to rise and fall through the screw transmission mechanism 22; the locking mechanism 23 automatically locks after the lifting position is reached.

[0015] The intelligent sensing system 3 includes a pressure sensor 31, a tilt sensor 32, a liquid level sensor 33, and a communication module 34; the pressure sensor 31 identifies vehicles and pedestrians; the tilt sensor 32 monitors the displacement of the manhole cover; the liquid level sensor 33 monitors the water level in the well; and the communication module 34 enables data uploading and remote command reception.

[0016] The intelligent control module 4 automatically controls the lifting and locking based on water level, tilt angle, and pressure signals. When the water level is too high, it raises the manhole cover to accelerate drainage. It also alarms when there is abnormal displacement and supports remote control.

[0017] The sealing assembly 5 includes an elastic sealing ring 51 and a dust cover 52, which achieves waterproof and dustproof protection and improves the service life of the equipment. Attached Figure Description
