[0035] like Figure 2 、 3 As shown in Figures 4, 6, and 8, the locking seat 300 is annular and embedded in the well seat 100. Its lower surface is supported on the seat ring 103 of the well seat 100. The locking seat 300 is provided with a fixing protrusion 301, an L-shaped buckle groove 302, a rotation hole 303, and an avoidance groove 304. The fixing protrusion 301 can pass through the clamping groove 102 of the well seat 100 and buckle the seat ring 103 of the well seat 100 after rotation. The L-shaped buckle groove 302 is provided on the inner ring of the locking seat 300, and the rotation hole 303 and the avoidance groove 304 are provided on the upper surface of the locking seat 300. The avoidance groove 304 is located at the fork-shaped block 203 of the well seat 100 and the cover plate 200. The rotation hole 303 is convenient for serving as a force point for the rotation of the locking seat 300. There are two rotation holes 303 that are blind holes.

[0036] like Figure 5 、 6As shown in Figure 7, the cover plate 200 is provided with an anti-slip texture 201 and a drain hole 202. The drain hole 202 is an airplane hole, and there are more than two of them, which are symmetrically arranged. The anti-slip texture 201 is located on the upper surface of the cover plate 200. The cover plate 200 is provided with a fork-shaped block 203, which is hinged to the well seat 100 by a pin. The cover plate 200 is provided with a safety buckle 205, which can be inserted into the L-shaped buckle groove 302 of the locking seat 300 to limit the vertical direction. The cover plate 200 is cast iron or composite material, and the anti-slip texture 201 is integrally formed with the cover plate 200. The bottom of the cover plate 200 is provided with criss-cross reinforcement ribs 305, and the reinforcement ribs 305 are integrally formed with the cover plate 200. The cover plate 200 is symmetrically provided with two semicircular lifting notches 204 to facilitate lifting the cover plate 200.

[0037] like Figure 4 、 5 As shown in Figures 7 and 9, the monitor 400 includes a wireless transceiver module, a control chip, a GPS module, a tilt sensor, a liquid level sensor, and a lithium battery. The monitor 400 is box-shaped and has a waterproof sealing structure. The liquid level sensor is suspended below the box body of the monitor 400.

[0038] The working principle of this utility model:

[0039] like Figure 1 、 2 As shown in Figure 6, when installing the present invention, first embed the manhole cover's seat 100 part into the ground and ensure that it is firmly fixed. The manhole seat 100 is the foundation of the manhole cover system, providing bearing capacity and stability. Then install the locking seat 300 on the manhole seat 100, insert the fixing protrusion 301 of the locking seat 300 into the slot 102 of the manhole seat 100 and rotate it a certain angle so that the locking seat 300 is fixed in place to ensure the subsequent structural stability. Then put the cover plate 200 of the manhole cover into the locking seat 300 and hinge it with the manhole seat 100. Rotate the locking seat 300 again so that the "L"-shaped safety buckle 205 is stuck in the L-shaped buckle slot 302 to ensure that the manhole cover as a whole is fixed and locked. Note that the locking seat 300 will not fall out of the manhole seat 100 during rotation at this time. The locking seat 300 is then locked by a key and a safety lock 101 on the well seat 100. The safety lock 101 can be a rotating structure, and when rotating, the blocking piece is stuck in the notch on the edge of the locking seat 300. The safety lock 101 can also be a latch, which is inserted into the socket on the edge of the locking seat 300 when pressed down, and can also be pulled out by a key.

[0040] like Figure 5As shown, when the manhole cover needs to be opened, the safety lock 101 is unlocked and the locking base 300 is rotated in different directions through the two holes on the locking base 300 to release the locked state, thus easily opening the manhole cover. The complex rotation structure and the design of the safety buckle 205 snapping into the L-shaped buckle slot 302 prevent the manhole cover from being easily opened due to theft or improper operation, effectively reducing the risk of loss or theft of the manhole cover, making it particularly suitable for the management of urban public facilities. It also prevents the manhole cover from being easily opened due to vibration, impact, etc., thus preventing safety accidents.

[0041] like Figure 9 As shown, the utility model is equipped with a monitor 400, which can monitor in real time whether the manhole cover is tilted or shifted. If the manhole cover is stolen, damaged, or shifted due to external forces (such as vehicle collisions), it will be detected immediately and an alarm will be issued to ensure that the manhole cover is dealt with in a timely manner when problems occur and to avoid safety hazards. Through GPS, smart manhole covers can achieve dynamic tracking, which is convenient for urban management personnel to carry out location management and scheduling. The water level changes in the well can be monitored in real time, which is especially important for manhole covers such as drainage wells and sewage wells. When the water level is too high (for example, during heavy rain or when the drainage pipe is blocked), the sensor will sound an alarm to help deal with drainage problems in a timely manner and prevent waterlogging on the road or waterlogging. The lithium battery of the utility model has a long service life and high energy density, which can provide long-lasting power support for various sensors on the manhole cover, and the standby time is not less than 5 years. The manhole cover monitor 400 can choose Zhengzhou Gaohua GH-L201. The following are the specific parameters of the manhole cover monitor 400:

[0042] External dimensions: 130*118*40.5mm;
