[0002] With the accelerating urbanization process and the continuous high-speed development of urban infrastructure construction in my country, the number of underground pipelines for various municipal utilities such as water supply, drainage, gas, heating, electricity, and communications is increasing daily. Consequently, the number of manholes on urban roads is also constantly increasing, making the management of urban road manhole covers increasingly important. Poor management of urban manhole covers has led to frequent incidents of injuries and vehicle damage across the country. Inadequate manhole cover management seriously affects the personal safety of citizens and causes adverse social impacts. How to improve and strengthen urban manhole cover management has become a difficult and pressing issue for municipal infrastructure management departments nationwide. Utility Model Content

[0003] The purpose of this utility model is to provide an intelligent safety protection device for urban manhole covers, so as to solve the problems of existing manhole covers being unable to be managed in batches and the high cost of replacing new smart manhole covers.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an intelligent safety protection device for urban manhole covers, comprising a housing, a gyroscope mounted in the center of the housing, a control center arranged around the gyroscope, laser ranging modules symmetrically arranged on the housing, and a fixing structure on the housing for connecting the housing to the manhole cover. This utility model utilizes the gyroscope and laser ranging modules to effectively determine the status of the manhole cover through an algorithm, and reports abnormal statuses in real time for convenient management.

[0005] As a further improvement to the above technical solution:

[0006] The fixed structure is a magnetic base module, which includes a magnetic base, a permanent magnet rotatably disposed within the magnetic base, and a second bevel gear connected to the permanent magnet. Rotating the second bevel gear drives the permanent magnet to rotate, thus opening and closing the magnetic base module. The housing has a cavity for accommodating the magnetic base. The magnetic base is fixedly installed within the cavity and integrated with the housing using bolt connections. The magnetic base module allows for quick and easy installation and removal from any existing manhole cover, offering convenience and versatility.

A rotating handle is provided on the rotating bearing, and a first bevel gear is provided on the rotating handle. The first bevel gear and a second bevel gear mesh. The outer ring of the rotating bearing is fixed to the magnetic base, and the inner ring is fixed to the rotating handle to ensure normal operation of the rotating handle. Rotating the rotating handle drives the first bevel gear to rotate, which in turn drives the meshing second bevel gear, thereby opening and closing the magnetic base.

[0008] The working surface of the magnetic base is located on the same plane as the upper surface of the housing.

[0009] The rotating handle passes through the placement cavity and protrudes from the lower surface of the housing.

[0010] The first bevel gear and the second bevel gear are 45-degree bevel gears meshing, and their module and number of teeth are equal.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Real-time monitoring: The device has a built-in gyroscope and laser ranging module, which can monitor the status of the manhole cover in real time. Once the manhole cover is abnormal, such as being open, not fully closed, or missing, the device can immediately detect it and upload early warning information.

[0013] Enhanced safety: Through the early warning system, management departments can promptly understand any abnormalities in manhole covers and take swift measures to effectively prevent safety accidents caused by manhole cover problems.

[0014] Easy installation: The magnetic base module fixing structure makes the installation process simple and quick, without complicated construction, thus reducing installation costs.

[0015] Improved management efficiency: This device enables unified management of a batch of manhole covers, allowing managers to monitor manhole cover information in real time and improving management efficiency.

[0016] Highly adaptable: The device is suitable for various types of manhole covers, has strong versatility, and can be widely used in urban roads, squares, parks and other places.

[0017] High level of intelligence: It adopts single-chip microcomputer control to realize intelligent identification, early warning and data uploading of manhole cover status, providing technical support for the construction of smart cities.

[0018] Aesthetically pleasing: The shell design is simple and blends into the urban environment without affecting the city's appearance. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 3As shown, the intelligent safety protection device for urban manhole covers in this embodiment includes a housing 3, a gyroscope 1 installed in the center of the housing 3, a control center 4 arranged around the gyroscope 1, laser ranging modules 5 symmetrically arranged on the housing 3, and a fixing structure 2 on the housing 3 for connecting the housing 3 to the manhole cover. The control center 4 has a built-in microcontroller, battery, and 2.4G signal module. In this embodiment, the housing 3 is installed on the manhole cover through the fixing structure 2. When the manhole cover opens or is not fully closed, the gyroscope 1 reads the angle change, and the control center 4 calculates and processes the change to send an early warning. When the manhole cover is missing and fails to return to its original position within the specified time, the data obtained by the two laser ranging modules 5 is detected by the control center 4 as being outside the preset range, and an early warning is also sent.

[0029] Specifically, in this embodiment, the fixing structure 2 is a magnetic base module. The magnetic base module includes a magnetic base 205, a permanent magnet rotatably disposed within the magnetic base 205, and a second bevel gear 204 connected to the permanent magnet. By rotating the second bevel gear 204, the permanent magnet is driven to rotate, thereby realizing the opening and closing of the magnetic base module. The housing 3 is provided with a placement cavity for accommodating the magnetic base 205. The working principle of the magnetic base module is as follows: Figure 4 As shown. A rotating bearing 202 is provided on the magnetic base 205, located opposite the working surface of the magnetic base module. A rotating handle 201 is provided on the rotating bearing 202, and a first bevel gear 203 is provided on the rotating handle 201. The first bevel gear 203 and the second bevel gear 204 mesh. The working surface of the magnetic base 205 is on the same plane as the upper surface of the housing 3. The rotating handle 201 passes through the placement cavity and protrudes from the lower surface of the housing 3. The first bevel gear 203 and the second bevel gear 204 are 45-degree bevel gears meshing, and their module and number of teeth are equal.

[0030] In use, the housing 3 of this embodiment is placed on the bottom of the manhole cover. By rotating the handle 201, the first bevel gear 203 drives the second bevel gear 204 to rotate and open the magnetic base, causing the housing 3 to be attracted to the manhole cover, thus completing the installation. The manhole cover status is subsequently identified using a gyroscope 1 and a laser ranging module 5; this identification method is existing technology and not detailed here. This utility model's intelligent safety protection device for urban manhole covers provides an effective solution for manhole cover management, effectively managing batches of manhole covers, timely obtaining manhole cover information, and ensuring safety.
