According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Manhole covers are generally divided into round and square. In urban road administration, round manhole covers are generally used because round manhole covers are not easy to tilt and can well protect the safety of pedestrians and vehicles. In the countryside and cable wells, square manhole covers are generally used, which can better prevent the entry of liquids such as rainwater. When installing conventional manhole covers, after the installation frame is installed on the ground, the top of the installation frame is rotated and connected to the cover body, and the top of the installation frame is shielded by the cover body. The inner wall of the installation frame is provided with a drain port, and the water flow from the outside is discharged by the drain port.

[0003] With respect to the above-mentioned related technologies, the inventors believe that conventional manhole covers are often installed on the upper end of the road surface, so there are many vehicles passing by frequently. The functions of ordinary manhole covers are limited.

[0021] The present application embodiment discloses a manhole cover pressure monitoring system, referring to Figure 1 - Figure 2 , including an installation frame 1. During installation, after the installation frame 1 is installed on the ground, the top of the installation frame 1 is rotatably connected to a cover body 2, and the top of the installation frame 1 is shielded by means of the cover body 2. A drain port 3 is opened on the inner wall of the installation frame 1, and the external water flow is discharged by means of the drain port 3. A connecting frame 4 is slidably connected to the inner wall of the cover body 2, and a pressure plate 8 is fixedly installed on one end of the connecting frame 4, and rotating plates 9 are rotatably connected to both ends of the pressure plate 8. A weighing device 5 is installed on the inner wall of the installation frame 1, and a controller 7 is installed on one end of the weighing device 5 by means of a connecting pipe 6. The weighing device 5 is installed on the surface of the cover body 2 by means of the pressure plate 8 and the rotating plate 9, and contacts with a moving vehicle by means of the pressure plate 8 and the rotating plate 9. The connecting frame 4 at one end of the pressure plate 8 contacts with the top of the weighing device 5. After the weighing device 5 weighs the vehicle, the information is transmitted to the controller 7, and the controller 7 facilitates the monitoring of the moving vehicle.

[0022] Reference Figure 2 A number of supporting springs 11 are installed on the surface of the connecting frame 4, one end of the supporting spring 11 is fixedly connected to one end of the pressing plate 8, and when the pressing plate 8 is under pressure, it rebounds with the help of the supporting spring 11 to reset the pressing plate 8, effectively ensuring the use effect of the device, avoiding the pressing plate 8 being difficult to lift up after being attached to the surface of the cover body 2, causing the weighing device 5 to remain in a weighing state, and two rollers 10 are rotatably installed on the inner wall of the rotating plate 9. When one end of the rotating plate 9 contacts the ground, the friction between the rotating plate 9 and the ground is reduced with the help of the rollers 10, avoiding the wear of one end of the rotating plate 9 against the ground, effectively ensuring the use effect of the rotating plate 9.
