[0040] In order to solve the technical problem of the current untimely mastery and maintenance of manhole cover conditions and the large management difficulty caused by information asymmetry, the present utility model proposes a manhole cover 100.

[0041] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the manhole cover 100 includes a base 100, a cover body 2, a control lock 3, a processor 4, a sensor unit 5, and an Internet of Things module 6. The base 100 has a receiving cavity with at least one side open; the cover body 2 is rotatably connected to the base 100 and covers the opening of the receiving cavity; the control lock 3 is disposed on the side of the cover body 2 facing the base 100 for locking the cover body 2 to the base 100; the processor 4 is disposed on the side of the cover body 2 facing the base 100 and is electrically connected to the control lock 3 for controlling the opening or locking of the control lock 3; the sensor unit 5 is disposed on the side of the cover body 2 facing the base 100 for detecting the condition information of the manhole cover 100; the Internet of Things module 6 is disposed on the side of the cover body 2 facing the base 100 and is electrically connected to the processor 4 and the sensor unit 5.

[0042] In this embodiment, the cover body 2 is rotatably connected to the base 100. Optionally, the cover body 2 is rotatably connected to the base 100 through the cooperation of a rotating shaft and a rotating hole. The base 100 is a hollow structure with a receiving cavity, and at least one side of the receiving cavity is open, that is, the side facing the cover body 2 is open. During the rotation of the cover body 2, it can cover the opening of the receiving cavity or open the receiving cavity. The specific structures of the cover body 2 and the base 100 are not limited. The control lock 3, the processor 4, the sensor, and the Internet of Things module 6 are all arranged on the side of the cover body 2 facing the receiving cavity (i.e., the inner side). The specific setting method can be selected as screw fixation, bonding, or other reasonable methods, which are not limited here; the processor 4, as the hub for data collection, analysis, and receiving instructions, is used to receive and analyze the information detected by the sensor unit 5 and transmit the information to the Internet of Things module 6, which uploads it to the cloud server; at the same time, the opening or closing instruction of the cover body 2 received by the Internet of Things module 6 is transmitted to the processor 4, and the processor 4 controls the control lock 3 to open or lock. Among them, the specific structures of the control lock 3, the processor 4, the sensor, and the Internet of Things module 6 can refer to the prior art and are not limited as long as they can achieve the corresponding functions.

[0043] With the above settings, the Internet of Things wireless technology is combined with the sensor detection technology to implement intelligent management of the manhole cover 100. Among them, the sensor unit 5 can detect the condition information of the manhole cover 100 in real time, upload the condition information to the cloud server through the Internet of Things module 6, and make it available for users to view on the monitoring platform to achieve remote monitoring and management of the manhole cover 100, which is conducive to making timely maintenance, and the information is equal, effectively reducing the management difficulty; at the same time, the opening or locking of the control lock 3 can be controlled through the Internet of Things module 6 and the processor 4, and then the opening and closing of the cover body 2 can be realized, that is, the remote control of the manhole cover 100 can be realized to facilitate maintenance operations; and, the structure setting is relatively simple and the design is relatively reasonable, which is suitable for the management of the manhole cover 100 in urban traffic.

[0044] In an alternative embodiment of the present utility model, the sensor unit 5 includes at least one of a gas detection sensor, a water level sensor, a displacement detection sensor, a six-axis sensor, and a temperature and humidity sensor. Among them, the gas detection sensor is used to detect the gas concentration, mainly for detecting the concentration of combustible gases at the manhole cover 100, such as combustible gases like sulfur dioxide, carbon monoxide, methane, carbon dioxide, etc.; the water level sensor calculates the liquid level position by ultrasonic waves, and calculates the liquid level through the time interval between the emitted and received ultrasonic waves; the displacement detection sensor is used to detect the displacement amount of the manhole cover 100; the six-axis sensor is used to remotely monitor the opening and closing state of the manhole cover 100. The six-axis sensor can be selected as a combination of a gyroscope and an accelerometer. Among them, the accelerometer can measure the inclination degree of the manhole cover 100, and the gyroscope can measure the rotational movement of the manhole cover 100 itself. Through the six-axis sensor, the opening and closing state of the manhole cover 100 can be remotely monitored; the temperature and humidity sensor is used to detect the temperature and humidity of the environment under the manhole cover 100. If the corresponding data detected by the above sensors exceeds the preset threshold, the system will issue an alarm. Among them, the data detected by the above sensors is uploaded to the cloud server through the Internet of Things module 6 and is available for users to view on the monitoring platform.

[0045] Please refer to again Figure 3 and Figure 4 In an embodiment, the control lock 3 includes an electric lock 31 and a controller 32. The controller 32 is electrically connected to the electric lock 31 and the processor 4. With such a setting, the opening or closing instruction of the cover body 2 received by the Internet of Things module 6 is transmitted to the processor 4, and the processor 4 sends an opening or closing instruction to the controller 32, thereby controlling the control lock 3 to open or lock.

[0046] Since the digital signal current of the processor 4 is relatively weak and cannot directly and effectively control the locking or opening of the electric lock 31, optionally, a relay is provided in the controller 32 for controlling the on-off of the contact point. When the change in the input quantity reaches the threshold value, a step change occurs in the output terminal circuit, realizing the control of a large current by a small current. In this way, the locking or opening of the electric lock 31 can be effectively and quickly controlled.

[0047] In an embodiment, the electric lock 31 includes a turntable 311 and a lock rod 312. The turntable 311 is rotatably arranged on the side of the cover body 2 facing the base 100; the lock rod 312 is movably connected to the turntable 311 and can move radially along the turntable 311 under the rotation of the turntable 311; the lock rod 312 can be clamped to the base 100 during the movement process, so that the cover body 2 is locked and connected to the base 100.

[0048] Specifically, the turntable 311 is rotatably fixed on the surface of the cover body 2 facing the accommodating cavity. The fixing method can be selected as the cooperation between the rotating shaft and the rotating hole. The locking rod 312 is movably connected to the middle of the turntable 311. When the turntable 311 rotates in a certain direction, the locking rod 312 moves radially away from the turntable 311 (i.e., towards the base 100). The end of the locking rod 312 away from the turntable 311 can be clamped to the base 100 to lock the cover body 2 to the base 100. Conversely, when the turntable 311 rotates in the opposite direction, the locking rod 312 moves radially towards the turntable 311, causing the locking rod 312 to disengage from the base 100, so that the cover body 2 can be opened.

[0049] Optionally, the electric lock 31 adopts a three-axis electronic lock, that is, three locking rods 312 are provided. The three locking rods 312 are evenly distributed along the circumferential direction of the turntable 311, and each locking rod 312 can be movably connected to the turntable 311 and can move radially along the turntable 311 under the rotation of the turntable 311 to be clamped to the base 100. With such a setting, the locking of the cover body 2 and the base 100 is relatively firm and the safety is relatively high.

[0050] It should be noted that the locking rod 312 can adopt a segmented structure, such as a two-segment structure, which is convenient for the processing and manufacturing of the locking rod 312 and also convenient for the assembly operation of the locking rod 312.

[0051] Furthermore, in an optional embodiment, the electric lock 31 further includes a lock sleeve 313. The lock sleeve 313 is arranged on the side of the cover body 2 facing the base 100. The locking rod 312 can movably pass through the lock sleeve 313. The specific structure of the lock sleeve 313 is not limited as long as it can define a sleeve hole extending along the length direction of the locking rod 312. The lock sleeve 313 plays a role in limiting the movement process of the locking rod 312 to prevent the locking rod 312 from shifting during the movement process and ensure the reliability of the electric lock 31.

[0052] It should be noted that when the electric lock 31 adopts a three-axis electronic lock, that is, three locking rods 312 are provided, three lock sleeves 313 are correspondingly provided, and one locking rod 312 can movably pass through one lock sleeve 313.

[0053] Furthermore, in an optional embodiment, the electric lock 31 further includes a mounting plate 315, a hose 314 and a limiting member 316. The mounting plate 315 is fixed on the side of the cover body 2 facing the base 100. The turntable 311 is rotatably fixed on the mounting plate 315. The two ends of the hose 314 are respectively connected to the turntable 311 and the locking rod 312. The limiting member 316 is fixed on the surface of the mounting plate 315 facing the turntable 311. The limiting member 316 is provided with a limiting hole (not shown) extending radially along the turntable 311. The locking rod 312 can movably pass through the limiting hole.

[0054] Specifically, the specific structure of the mounting plate 315 is not limited. The mounting plate 315 can be fixed on the surface of the cover body 2 facing the accommodating cavity by means of screws. The turntable 311 can be fixed on the surface of the mounting plate 315 facing away from the cover body 2, and its specific fixing method is not limited. One end of the locking rod 312 is connected to the turntable 311 by a hose 314. During the rotation of the turntable 311, the hose 314 can be bent or stretched, so as to ensure that the locking rod 312 moves along the radial direction of the turntable 311. The length of the hose 314 can be determined according to the moving displacement of the locking rod 312, as long as it can ensure that the locking rod 312 moves and is clamped to the base 100. The limiting member 316 is arranged on the surface of the mounting plate 315 facing away from the cover body 2, and can be fixed by screws or integrally formed. The limiting member 316 is provided with a limiting hole extending along the radial direction of the turntable 311 for the locking rod 312 to pass through movably, so as to effectively ensure that the locking rod 312 can only move along the radial direction of the turntable 311.

[0055] It should be noted that when three locking rods 312 are provided, three hoses 314 are correspondingly provided, which are respectively connected to the three locking rods 312 and the turntable 311, and three limiting members 316 are correspondingly provided to limit the three locking rods 312 respectively, so as to ensure that the locking rods 312 can only move along the radial direction of the turntable 311.

The main control box 10 is arranged on one side of the cover body 2 facing the base 100. The processor 4, the sensor unit 5 and the Internet of Things module 6 are all arranged in the main control box 10.

[0057] In this embodiment, the main control box 10 is provided to place modules such as the processor 4, the sensor unit 5 and the Internet of Things module 6, which can play a protective role for these modules and is beneficial to extending the service life of the manhole cover 100. It should be noted that the main control box 10 is provided with a detection port corresponding to the sensor unit 5 to realize the detection of the sensor unit 5.

[0058] Please refer to Figure 5 In an embodiment, the manhole cover 100 further includes a positioning module 7. The positioning module 7 is arranged in the main control box 10 and is electrically connected to the processor 4. In this embodiment, the positioning module 7 is a Beidou positioning module 7. The Beidou positioning module 7 can optionally adopt an ATK-S1216F8-BD type GPS / Beidou module. The ATK-S1216F8-BD type GPS / Beidou module supports multiple communication baud rates and is connected to the processor 4 module through a serial port. When the manhole cover 100 has a fault alarm, the staff can locate the faulty manhole cover 100 in time, which is convenient for maintenance.

[0059] Please refer to Figure 1 and Figure 5, in one embodiment, the manhole cover 100 further includes a solar battery 8 and a solar module 9 which are electrically connected. The solar battery 8 is disposed in the main control box 10 and is electrically connected to the control lock 3, the processor 4, the sensor unit 5 and the Internet of Things module 6. The solar module 9 is disposed on the side of the cover body 2 facing away from the base 100.

[0060] In this embodiment, the solar module 9 is disposed on the outer surface of the cover body 2. Optionally, an installation groove is provided on the outer surface of the cover body 2, and the solar module 9 is fixed in the installation groove for receiving solar energy and converting the solar energy into electrical energy to provide power supply for the manhole cover monitoring system; the solar battery 8 is electrically connected to the solar module 9 through a connecting wire for receiving the electrical energy converted by the solar module 9 and providing electrical energy for each module.

[0061] Please refer to Figures 1 to 3 , in one embodiment, a connection hole 231 is further provided on the side of the cover body 2 facing the base 100. The connection hole 231 extends along a direction parallel to the covering surface of the cover body 2 and the base 100; the manhole cover 100 further includes a connecting shaft 24 and a torsion spring 25. The connecting shaft 24 passes through the connection hole 231 and at least one end thereof is exposed outside the connection hole 231. The torsion spring 25 is sleeved on the exposed end of the connecting shaft 24, and the two free ends of the torsion spring 25 are respectively elastically abutted against the cover body 2 and the base 100.

[0062] Specifically, the cover body 2 includes a covering portion 21 and an assembling portion 22 which are connected. When the cover body 2 is locked with the base 100, the assembling portion 22 is located inside the opening of the accommodating cavity, and the covering portion 21 covers the end surface of the base 100; the control lock 3, the processor 4, the sensor unit 5 and the Internet of Things module 6 are all disposed on the side of the assembling portion 22 away from the covering portion 21; the base 100 includes a main body portion 11 and an installation portion 12 protruding from one side of the main body portion 11. The main body portion 11 is rotatably connected to the assembling portion 22 and is adapted to each other. The installation portion 12 is disposed opposite to the rotation connection position. The assembling portion 22 is correspondingly provided with a fixing portion 23. The shape of the fixing portion 23 is adapted to the shape of the installation portion 12, and the size of the fixing portion 23 is smaller than the size of the installation portion 12. When the cover body 2 is locked with the base 100, the assembling portion 22 is located inside the main body portion 11, the fixing portion 23 is located inside the installation portion 12, and there is a gap; the connection hole 231 is opened on the fixing portion 23 and penetrates through two opposite side surfaces of the fixing portion 23; the manhole cover 100 further includes a connecting shaft 24 and a torsion spring 25. The connecting shaft 24 passes through the connection hole 231, at least one end of the connecting shaft 24 is exposed outside the fixing portion 23 and is located in the gap, the torsion spring 25 is located in the gap and is sleeved on the exposed portion of the connecting shaft 24, and the two free ends of the torsion spring 25 are respectively elastically abutted against the covering portion 21 and the installation portion 12. With such a setting, when the electric lock 31 is opened, the cover body 2 can be pushed open under the elastic force of the torsion spring 25, saving labor.

[0063] Optionally, both ends of the connecting shaft 24 are exposed outside the fixing part 23 and located in the gap. Two torsion springs 25 are provided. The two torsion springs 25 are correspondingly sleeved on the two exposed ends of the connecting shaft, and the two free ends of each torsion spring 25 are elastically abutted against the covering part 21 and the mounting part 12 respectively. With such a setting, the elastic force of the torsion spring 25 is relatively large. When the electric lock 31 is opened, the cover body 2 can be pushed open more effectively and quickly under the elastic force of the torsion spring 25, saving more labor.
