DETAILED DESCRIPTION

[0040] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , an embodiment of the present invention provides a manhole cover with real-time monitoring and alarm functions, including a battery module 1, a control module 2, a lock core module 3, a turntable mechanism 4, a lock rod mechanism 5, a lock hole bracket 6 and a sensor assembly 7;

[0042] Among them, the control module 2, the lock core module 3, and the sensor assembly 7 are all electrically connected to the battery module 1, and the battery module 1 is used to supply power to the control module 2, the lock core module 3, and the sensor assembly 7;

[0043] Among them, the lock core module 3 and the control module 2 are electrically connected, the turntable mechanism 4 is connected to the lock core module 3, and the lock rod mechanism 5 is connected to the turntable mechanism 4; the lock core module 3 is used to adjust the locking state of the turntable mechanism 4, and the lock core module 3 is restricted from driving the turntable mechanism 4 to rotate in the locked state; the lock core module 3 is allowed to drive the turntable mechanism 4 to rotate in the unlocked state;

[0044] In the unlocked state, the rotary disc mechanism 4 drives the locking rod mechanism 5 to extend and retract to move in and out of the locking hole bracket 6, and the locking rod mechanism 5 moves in and out of the locking hole bracket 6 to put the manhole cover in a locked state or an unlocked state;

[0045] The sensor component 7 is electrically connected to the control module 2, and the sensor component 7 is used to monitor the state change of the manhole cover to perform real-time monitoring and alarm.

[0046] See also Figure 1 In this embodiment, the lock hole bracket 6 is fixed under the first manhole cover 8, and the battery module 1, the control module 2, the lock core module 3, the turntable mechanism 4, the locking rod mechanism 5, and the sensor assembly 7 are fixed under the second manhole cover 9 adjacent to the first manhole cover 8.

[0047] Specifically, taking the first manhole cover 8 and the second manhole cover 9 as an example, because the lock hole bracket 6 is fixed under the first manhole cover 8, and the matching battery module 1, control module 2, lock core module 3, turntable mechanism 4, locking rod mechanism 5, and sensor assembly 7 are fixed under the second manhole cover 9 adjacent to the first manhole cover 8, and so on. When there are multiple manhole covers, the multiple manhole covers are interlocked to effectively prevent theft.

[0048] See also Figure 4 and Figure 5In this embodiment, the lock core module 3 includes a lock core body 10 and an electric push rod 11; a switch lock hole is formed in the center of the lock core body 10, and a locking hole 12 is formed on the side of the lock core body 10, and a spring lock pin 13 is configured in the locking hole 12; the electric push rod 11 drives the spring lock pin 13 to extend into the locking hole 12, so that the lock core module 3 and the turntable mechanism 4 are linked; the turntable mechanism 4 includes a turntable drum 14, a flange 15 and a turntable body 16; the turntable drum 14 is formed with a matching hole 17, and the electric push rod 11 drives the spring lock pin 13 to be locked by the matching hole 17. The hole 17 extends into the locking hole 12 so that the lock core module 3 and the turntable mechanism 4 are linked; the flange 15 is connected to the end of the turntable drum 14, and the turntable body 16 is connected to the flange 15; the lock rod mechanism 5 is connected to the turntable body 16; the lock rod mechanism 5 includes a first lock rod 18 and a second lock rod 19; one end of the first lock rod 18 is hinged to the edge of the turntable body 16, the other end of the first lock rod 18 is hinged to one end of the second lock rod 19, and the other end of the second lock rod 19 extends out of the in-and-out lock hole bracket 6 to put the manhole cover in a locked state or an unlocked state. In addition, a mechanical key is also configured, which is inserted into the switch lock hole to rotate the turntable mechanism 4 through the lock core module 3 to unlock or lock.

[0049] Specifically, the electric push rod 11 can push the spring lock pin 13 into the locking hole 12. When one end of the spring lock pin 13 is in the locking hole 12 and the other end of the spring lock pin 13 is in the matching hole 17 on the turntable drum 14, the lock hole is turned by the matching mechanical key. At this time, the lock core module 3 and the turntable mechanism 4 can be linked, that is, the turntable drum 14 drives the turntable body 16 to rotate through the flange 15. When the turntable body 16 rotates, the first lock rod 18 and the second lock rod 19 of the lock rod mechanism 5 hinged to the turntable body 16 can be extended and retracted, so that the second lock rod 19 can enter and exit the lock hole bracket 6 to put the manhole cover in a locked state or an unlocked state.

[0050] It should be noted that when the manhole cover is in the locked state, it cannot be opened manually, and when the manhole cover is in the unlocked state, it can be opened manually. The locked state of the turntable mechanism 4 is only to enable the lock core module 3 and the turntable mechanism 4 to be linked, and then the lock core module 3 can drive the turntable mechanism 4, and further drive the lock rod mechanism 5. When the turntable mechanism 4 is in the unlocked state, the lock core module 3 and the turntable mechanism 4 cannot be linked, even if the lock hole is rotated by the matching mechanical key, the lock core module 3 will only idle, and the control of the locked state and unlocked state of the manhole cover cannot be realized.

[0051] In this embodiment, the edge of the turntable body 16 is also connected to a first position sensing probe 20 and a second position sensing probe 21; the first position sensing probe 20 and the second position sensing probe 21 are both electrically connected to the control module 2; when the first position sensing probe 20 is sensed by the sensing probe receiver 22 fixed at the lower end of the manhole cover, the manhole cover is in a locked state; when the second position sensing probe 21 is sensed by the sensing probe receiver 22 fixed at the lower end of the manhole cover, the manhole cover is in an unlocked state.

[0052] Specifically, when the manhole cover is in a locked state, the first position sensing probe 20 is sensed by the sensing probe receiver 22 fixed at the lower end of the manhole cover, and when the manhole cover is in an unlocked state, the second position sensing probe 21 is sensed by the sensing probe receiver 22 fixed at the lower end of the manhole cover, thereby remotely monitoring the locked and unlocked states of the manhole cover. It should be understood that the unlocked state of the manhole cover only allows the manhole cover to be opened manually, and the manhole cover is not necessarily in an open state in the unlocked state.

[0053] In this embodiment, the sensor assembly 7 includes at least one of a displacement sensor, a pressure sensor and a vibration sensor. The sensor assembly 7 senses the displacement signal, pressure signal or vibration signal of the manhole cover to determine whether the manhole cover is subjected to abnormal impact or damage. It also includes a wireless communication module, which is electrically connected to the control module 2. The wireless communication module is used to transmit the manhole cover status and abnormal alarm information to the management terminal; the abnormal alarm information includes the location of the manhole cover, the abnormal type and the occurrence time.

[0054] Specifically, the displacement sensor, pressure sensor and vibration sensor can sense the state change of the manhole cover in real time, and transmit the data to the main control module for processing. For example, when the manhole cover is illegally opened or moved, the displacement sensor will immediately sense the change and send a signal; when the manhole cover is subjected to abnormal impact or damage, the vibration sensor and pressure sensor will also send out an alarm signal accordingly. In this way, the state of the manhole cover can be monitored around the clock and without blind spots. Once abnormal conditions such as displacement, damage or illegal opening of the manhole cover are found, the alarm mechanism will be immediately activated and the information will be quickly transmitted to relevant departments and personnel. This immediate response speed not only effectively prevents safety accidents caused by manhole cover problems, but also greatly reduces property losses caused by untimely handling.

[0055] After receiving the data from the sensor assembly 7, the main control module determines whether the manhole cover is in a normal state through a preset algorithm and threshold. Once an abnormal situation is detected, the main control module will immediately trigger an alarm mechanism and send the alarm information to the management personnel through the wireless communication module. At the same time, the main control module will also record the real-time status data of the manhole cover to provide data support for subsequent troubleshooting and maintenance.

[0056] The wireless communication module adopts a low-power design to ensure stable operation even in long-term standby mode. When the main control module triggers the alarm mechanism, the wireless communication module will immediately start and send the alarm information to the management personnel through the wireless network. The alarm information includes detailed information such as the location of the manhole cover, the type of abnormality, and the time of occurrence, which is convenient for the management personnel to quickly locate and deal with the problem.

[0057] See also Figure 6 In an embodiment of the present invention, a manhole cover control method with real-time monitoring and alarm function is also provided, comprising the following steps:

[0058] S1. Adjust the locking state of the turntable mechanism 4 through the lock core module 3. In the locked state, the lock core module 3 is restricted from driving the turntable mechanism 4 to rotate; in the unlocked state, the lock core module 3 is allowed to drive the turntable mechanism 4 to rotate;

[0059] S2. When the manhole cover is unlocked, the rotary disc mechanism 4 drives the locking rod mechanism 5 to move out of the lock hole bracket 6, so that the manhole cover is in an unlocked state, allowing the manhole cover in the unlocked state to be manually opened;

[0060] S3, when the manhole cover is locked, the rotary disc mechanism 4 drives the locking rod mechanism 5 to enter the lock hole bracket 6, so that the manhole cover is in a locked state, and manual opening of the manhole cover in the locked state is restricted;

[0061] S4, when the manhole cover is locked: obtaining a displacement signal, a pressure signal or a vibration signal of the manhole cover, and judging whether the manhole cover is subjected to abnormal impact or damage according to the displacement signal, the pressure signal or the vibration signal of the manhole cover;

[0062] S5. When the manhole cover is subjected to abnormal impact or damage, the manhole cover status and abnormal alarm information are transmitted to the management terminal; the abnormal alarm information includes the location of the manhole cover, the abnormal type and the occurrence time.

[0063] In a possible embodiment, the sensor component 7 can select optional configurations of multiple sensors such as temperature, humidity, water immersion, smoke, vibration, etc. as needed, and can be customized according to actual needs to expand the functions and application scenarios of the manhole cover.

[0064] For example, when potential risks arise, such as an abnormal rise in the water level under the manhole cover or abnormal fluctuations in the temperature of the pipeline, an alarm will be issued in advance to remind relevant departments to take measures to avoid further deterioration of the problem and ensure the safety and stable operation of urban infrastructure.

[0065] In a possible embodiment, the manhole cover is locked and unlocked through Bluetooth authorization, remote unlocking, emergency keys and other methods, effectively preventing the risk of the manhole cover being stolen or damaged. At the same time, its anti-pry, anti-shear and other safety features provide double protection for the safety of the manhole cover. As a result, the manhole cover also has multiple functions such as remote control and information sharing. Managers can remotely monitor the status of the manhole cover through terminal devices such as mobile phones and computers, and remotely lock or unlock the manhole cover to improve the flexibility and efficiency of management. At the same time, the smart lock manhole cover can also upload monitoring data to the cloud platform to realize centralized storage and analysis of data, providing strong data support for urban management.
