[0002] In order to keep the urban environment clean and tidy during urban construction, a large number of underground pipelines are built. These pipelines must have a pit leading to the ground at intervals for easy maintenance. A pit cover is usually set at the pit mouth, forming a whole with the ground to facilitate the passage of pedestrians and vehicles. However, in the rainy season, the pit cover needs to be pulled out to allow rainwater to flow quickly into the pit for drainage, thereby avoiding sewage accumulation in the city.

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0023] Example:

[0024] like Figures 1 to 4 As shown, the utility model provides a manhole cover missing warning device, including a mounting seat 1, a manhole cover 3 is arranged above the mounting seat 1, a limiting groove 2 is opened on the top of the mounting seat 1, and the manhole cover 3 is clamped in the limiting groove 2. The limiting groove 2 can effectively limit the movement range of the manhole cover 3, and can ensure that the position of the manhole cover 3 is limited in the mounting seat 1, which helps to ensure that the manhole cover 3 will not move or fall off easily.

[0025] A plurality of pressure sensors 4 are arranged at the bottom of the mounting base 1, and a clamping block 8 is arranged at the top of the pressure sensor 4. The pressure sensor 4 is clamped in the mounting base 1 through the clamping block 8. When the pressure sensor 4 has a problem or needs maintenance, the user can easily remove it from the mounting base 1. This modular structure allows the pressure sensor 4 to be easily installed and removed, making the device more flexible. The user can adjust or replace the sensor as needed to adapt to different environments or needs.

[0026] A contact 5 is provided on one side of the block 8, and one end of the contact 5 is inserted into the limiting groove 2. When the manhole cover 3 is stuck in the limiting groove 2, the contact 5 will be squeezed, and when the manhole cover 3 is separated from the limiting groove 2, the squeezed contact 5 will lose pressure. At this time, the pressure sensor 4 will detect the change in pressure, thereby controlling its motor 16 to raise its warning light 11 to produce its warning effect, which effectively avoids accidents to pedestrians or vehicles. This structure can monitor the state changes of the manhole cover 3 in real time, promptly detect the movement or loss of the manhole cover 3, and can automatically start and respond quickly, thereby effectively reducing the incidence of accidents.

[0027] like Figures 2 to 5As shown, a plurality of fixing rods 6 are provided under the mounting base 1, and a clamping block 8 is provided on one side of the fixing rod 6. The fixing rod 6 is fixed to the inner side surface of the mounting base 1 through the clamping block 8. When there is a problem with the structure inside the fixing rod 6, the user can quickly disassemble it and repair or replace it. The user can quickly disassemble the fixing rod 6 and perform necessary repair or replacement work, which simplifies the maintenance process and reduces intervention in the equipment, thereby reducing the risk of damaging the equipment or introducing other problems. This helps to ensure the safety and effectiveness of the maintenance process.

[0028] A power supply box 7 is provided on one side of the block 8, and multiple power supply boxes 7 together power the electronic equipment on the device. A motor 16 is provided on the power supply box 7, and a holder 15 is provided in the fixing rod 6. The inner side surface of one side of the fixing rod 6 and the top of the holder 15 are both provided with a bevel gear 14. One side of the two sets of bevel gears 14 are mutually clamped, and one end of the motor 16 passes through the fixing rod 6 and is clamped in the bevel gear 14. When the manhole cover 3 moves or is lost, the pressure sensor 4 will send a signal to its motor 16, and the rotation of the motor 16 will drive the horizontal bevel gear 14, thereby driving the vertical bevel gear 14 to control the lifting and lowering of its warning structure. Since the structure is driven by the motor 16, the warning structure on the device can quickly respond to the movement or loss of the manhole cover 3, so that it can timely issue warnings to pedestrians or vehicles, thereby reducing the occurrence of accidents.

[0029] A warning light 11 is provided above the fixed rod 6. When the manhole cover 3 is lost or moved, the warning light 11 will rise upward through the transmission component and then start to flash, thereby warning pedestrians and vehicles around it to avoid accidents. A movable rod 9 is passed through the vertical bevel gear 14, and a fixed seat 10 is provided on the top of the movable rod 9. The bottom of the warning light 11 is stuck in the fixed seat 10. When the motor 16 starts to run, it will drive its vertical bevel gear 14 to control the lifting and lowering of its movable rod 9.

[0030] A water level sensor 12 is provided at the bottom of the warning light 11. When the water level rises, the water level sensor 12 will send a signal to the motor 16, thereby further raising the position of the warning light 11 to ensure that the warning light 11 can still be effectively seen when the water level rises. A LoRa communication module 13 is provided on the top of the warning light 11. The LoRa communication module 13 is a wireless communication device or system based on long-distance, low-power wireless communication technology, which is used to realize long-distance, low-power, and low-cost Internet of Things applications. When the manhole cover 3 moves or is lost, the pressure sensor 4 will also transmit its signal to the LoRa communication module 13. Through the LoRa communication module 13, the location information and alarm signal can be quickly sent to the relevant departments so that the relevant departments can know their specific situation.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When flooding occurs in the city, relevant personnel will remove the manhole cover 3 to allow rainwater to quickly flow into the kiln well for drainage. At this time, the pressure sensor 4 will detect the change in pressure and send its signal to its motor 16. The rotation of the motor 16 will drive its two sets of bevel gears 14 to control the lifting and lowering of its movable rod 9, so that the warning light 11 is exposed to produce a warning effect, thereby avoiding accidents to pedestrians or vehicles. When the water level begins to rise, the water level sensor 12 will send a signal to its motor 16 to further increase the position of the warning light 11 to ensure that the warning light 11 can still be effectively seen when the water level rises, and the LoRa communication module 13 on the warning light 11 will send location information and alarm information to its relevant departments so that the relevant departments can know its specific situation.

[0033] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
