Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manhole covers, and in particular to an intelligent manhole cover. Background Art

[0002] With the acceleration of urbanization and the growing demand for intelligent infrastructure, traditional manhole covers are increasingly unable to meet the requirements of modern urban management due to their limited functionality and insufficient security. Ordinary manhole covers typically utilize mechanical locks (such as snap locks and padlocks) or physical reinforcement structures, and can only be opened and closed using a physical key, lacking active protection. These manhole covers are highly susceptible to failure in the face of theft, vandalism, or natural disasters. For example, stolen manhole covers can create "road traps," leading to frequent pedestrian falls. Furthermore, mechanical locks are easily pried open or technically unlocked, resulting in weak anti-theft performance. Management methods that rely on manual inspections are not only inefficient but also fail to provide real-time visibility into the manhole cover's status, resulting in delayed response to incidents.

[0003] To address the above-mentioned issues, smart manhole cover technology has emerged. Its core goal is to improve the anti-theft capabilities and operation and maintenance efficiency of manhole covers through electronic and networked means, among which intelligent control of locks is a key link. However, existing smart manhole cover solutions still have significant technical defects. For example, some products only support Bluetooth or NFC near-field unlocking and cannot achieve remote authorization management, resulting in the municipal authorities being unable to intervene quickly when the manhole cover is stolen or urgently repaired; although some solutions have electronic lock functions, they lack status monitoring modules and cannot sense in real time whether the manhole cover has been illegally opened, displaced or damaged, making it difficult to detect potential accidents in a timely manner. In addition, existing technologies generally have the problem of a single unlocking method, relying only on electronic systems without designing physical emergency unlocking interfaces. Once the electronic system fails or the battery is exhausted, underground workers or trapped people will face life-threatening dangers due to the inability to open the manhole cover. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides an intelligent manhole cover, which effectively solves the problems that the existing manhole covers cannot be remotely unlocked and intervened, lack of real-time monitoring of the manhole cover status and underground environment, single unlocking method and no emergency unlocking guarantee.

[0012] Preferably, a cylindrical neodymium magnet is provided on the outer side of the slider, and a Hall sensor is provided on the outer side of the cylindrical neodymium magnet.

[0013] Preferably, the camshaft is made of iron.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention actively controls the rotation of the motor through a wireless communication module, utilizing the radial displacement changes generated by the special shape of the eccentric block to drive the movement of the slider and the safety pin, thereby releasing the constraints on the transmission rod. It is easy to operate and can be remotely controlled to meet daily operation and maintenance needs. When the transmission rod needs to be constrained again, the motor can be reversed to achieve reset, ensuring system stability and safety.

[0015] 2. In special circumstances, the first magnet at the bottom of the emergency unlocking key is used to attract the shaft upwards, and the power is transmitted to the camshaft through the shaft, pushing the slider to move outward, and manually releasing the constraint on the transmission rod, providing a reliable solution for emergency situations. Without the first magnet, the manual unlocking mechanism cannot be activated, thereby improving the safety of the system.

[0016] 3. When underground workers need to open the manhole cover, they only need to manually pull the bottom plate downward. After releasing the key slot at the bottom of the transmission rod, they can freely rotate the bottom plate and actively control the extension and retraction of the three cylindrical rods to complete the opening of the main body, providing an emergency operation method for underground operations.

In terms of electrical safety, the partition-type wiring harness terminals prevent interference and short circuits, grease ensures the stability of the wiring harness, and the moving parts are lubricated and protected to extend their service life. The overall design meets a 10-year service life and provides users with stable and efficient services. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figures 1-13 The specific embodiments of the present invention are described in further detail.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Depend on Figures 1-13 Given, the present invention proposes an intelligent manhole cover: The present invention includes a cover plate 101, which is made of high-strength composite material and is coated with a non-slip and wear-resistant coating on the surface. A shell 105 is provided at the bottom of the cover plate 101, and the shell 105 is a sealed and waterproof structure. The interior of the shell 105 is respectively provided with an external manhole cover detection module 102, a battery 106, a wireless communication module 108 and an antenna 107. The battery 106 is detachably connected to the shell 105. The external manhole cover detection module 102 adopts an anti-interference integrated design, and a high-sensitivity micro switch is integrated at the bottom. The top of the micro switch is fastened to an adjustable extension rod by a thread, and a high-elasticity spring ball is nested at the end of the extension rod. The spring ball is flexibly connected to the extension rod through a compression spring to form a dynamic adaptive structure. When the outer manhole cover is laterally displaced or tilted due to external forces (such as vehicle dragging or manual prying), the problem of traditional rigid structures being easily stuck or damaged by the manhole cover can be avoided. The battery 106 adopts a modular quick-release design, and the built-in power monitoring chip can collect the remaining power, voltage and charge and discharge status in real time. The wireless communication module 108 integrates dual-mode communication capabilities and supports the insertion of a standard Nano-SIM card to achieve 4G / NB-IoT wide area network remote communication. It can upload the manhole cover status, sensor data and abnormal alarms to the cloud platform in real time, and receive remote unlocking instructions or firmware upgrade packages; the module also has a built-in Bluetooth 5.0 chip and supports near-field communication function. Operation and maintenance personnel can use mobile phone APP or handheld terminal to perform parameter configuration, equipment debugging and emergency unlocking authorization within a range of 10 meters. The two communication modes can be automatically switched to ensure the reliability of data transmission.

[0035] A sleeve 203 is provided in the middle of the shell 105, and a limit block 202 is provided on the top of the sleeve 203. The sleeve 203 and the limit block 202 are fixedly connected to the shell 105 to provide support for the transmission rod 201. A transmission rod 201 is provided in the middle of the limit block 202, and a handle 103 is provided on the top of the transmission rod 201. A base plate 205 is provided at the bottom of the transmission rod 201, and the bottom is connected to the base plate 205 through a spline. A locking assembly is provided at the bottom of the base plate 205, and the handle 103 drives the transmission rod 201 and the base plate 205 to rotate, thereby realizing locking and unlocking of the locking assembly.

[0036] A support block 301 is provided on one side of the limit block 202. The bottom of the support block 301 is fixedly connected to the shell 105 to provide support for the control component. A control component is provided inside the support block 301. A slider 305 is provided in the middle of the control component. The control component can control the slider 305 to actively move. A safety pin 304 is provided on the outside of the slider 305. The safety pin 304 cooperates with the transmission rod 201. The movement of the slider 305 drives the safety pin 304 to move. The safety pin 304 can be inserted into the transmission rod 201, thereby restricting the rotation of the transmission rod 201.

[0037] A positioning pin 204 is located on one side of the transmission rod 201. The outer side of the positioning pin 204 is connected to the stop block 202, firmly connecting the outer side of the positioning pin 204 to the stop block 202, forming a retaining structure. An arc-shaped groove is defined within the transmission rod 201, tightly fitting the positioning pin 204. As the transmission rod 201 rotates, the positioning pin 204 slides along the groove, precisely constraining its rotation to a 90-degree range.

[0038] The control component includes a motor 302, the outer side of the motor 302 is connected to the support block 301, the top of the motor 302 is provided with an eccentric block 303, the eccentric block 303 has a special shape, the center of mass deviates from the center of rotation, the outer side of the eccentric block 303 is connected to the slider 305, the rear end of the safety pin 304 is provided with a first spring 306, the rear end of the first spring 306 and the support block 301 conflict with each other, under the action of the first spring 306, it can continuously give the slider 305 a force to move inward, the daily safety pin 304 is inserted into the transmission rod 201, so that the transmission rod 201 no longer rotates, when the motor 302 starts to rotate, it will drive the eccentric block 303 to rotate together, and as the eccentric block 30 3 rotates, and its special shape will produce radial displacement changes, thereby pushing the slider 305 to move outward. When the slider 305 moves, it compresses the first spring 306 and drives the safety pin 304 to move outward together. At this time, the safety pin 304 is disengaged from the transmission rod 201, successfully releasing the constraint on the transmission rod 201. When the transmission rod 201 needs to be further constrained, the motor 302 is controlled to reverse. Under the action of the first spring 306, the slider 305 and the safety pin 304 are actively reset, and the safety pin 304 is inserted into the transmission rod 201. At this time, the handle 103 cannot rotate, and the wireless communication module 108 can be used to actively control the rotation of the motor 302 to achieve active control.

[0039] A camshaft 405 is mounted on top of the slider 305. A rotating shaft 404 is mounted on top of the camshaft 405. A second spring 403 is mounted on top of the rotating shaft 404. A connecting shaft 402 is mounted on top of the second spring 403. The connecting shaft 402 is connected to the support block 301. An emergency unlocking key 104 is mounted inside the connecting shaft 402. A first magnet 401 is mounted on the bottom of the emergency unlocking key 104. When manual unlocking is required, the emergency unlocking key 104 is inserted into the connecting shaft 402. The first magnet 401 exerts a strong attraction, firmly pulling the rotating shaft 404 upward and tightly fitting it to the camshaft 405. At this point, turning the emergency unlocking key 104 precisely transmits power to the camshaft 405 via the rotating shaft 404, driving the camshaft 405 to rotate. The rotation of the camshaft 405 changes its contact position with the slider 305, pushing the slider 305 outward, thereby manually releasing the constraint on the transmission rod 201, allowing the system to resume normal operation or perform emergency operations. Without the adsorption effect of the first magnet 401, power cannot be effectively transmitted between the rotating shaft 404 and the camshaft 405, and the entire manual unlocking mechanism cannot be activated. This design greatly improves the safety and reliability of the system. The camshaft 405 is made of iron, and the other components are made of aluminum, so they are not attracted by the magnetic lock of the first magnet 401.

[0040] The locking assembly includes multiple connecting rods 206, and a cylindrical rod 207 is provided at the outer end of the connecting rod 206. A positioning block 208 is slidably connected to the outer side of the cylindrical rod 207. The top of the positioning block 208 is connected to the cover plate 101. When the transmission rod 201 drives the base plate 205 to rotate, the base plate 205 can drive the three hinged connecting rods 206 to deviate outward, and the connecting rod 206 can push the cylindrical rod 207 to move inward or outward at the same time. The positioning block 208 can limit the movement of the cylindrical rod 207. The extension of the cylindrical rod 207 can be connected to other components, so that the device body is fixed and stable. Otherwise, the device can be disassembled.

[0041] A third spring 209 is provided at the bottom of the transmission rod 201, and the top of the third spring 209 conflicts with the bottom of the bottom plate 205. When the underground workers need to open the main body in an emergency, they only need to manually pull the bottom plate 205 downward to release the key slot connection with the bottom of the transmission rod 201. Then, the bottom plate 205 can be rotated freely to actively control the extension and retraction of the three cylindrical rods 207, thereby completing the opening of the main body.

[0042] A cylindrical neodymium magnet 407 is mounted on the outside of slider 305, and a Hall sensor 406 is mounted on the outside of cylindrical neodymium magnet 407. This 2x3, high-temperature-resistant cylindrical neodymium magnet 407 is a small, strong magnet with a diameter of 2 mm and a height of 3 mm. Made of neodymium iron boron (NdFeB), it possesses both high magnetic properties and high-temperature resistance. These magnets are typically surface-coated (such as nickel) to enhance oxidation resistance and service life. Their operating temperature range is generally between 100°C and 200°C, with some high-performance models capable of withstanding higher temperatures. Hall sensor 406 is securely mounted on a specially designed bracket. The bracket's material provides excellent rigidity and stability, ensuring that the relative position between Hall sensor 406 and cylindrical neodymium magnet 407 remains constant. Hall effect sensor 406 is a magnetic sensor based on the Hall effect. It is extremely sensitive to magnetic field changes and can accurately detect even tiny variations in the surrounding magnetic field strength. When slider 305 moves, cylindrical neodymium magnet 407 also moves with it, causing the generated magnetic field distribution to change. Hall effect sensor 406 captures these magnetic field changes in real time and converts them into corresponding electrical signals for output. Upon receiving these signals, the control circuit rapidly analyzes and processes them. Because the insertion state of safety pin 304 is closely related to the position of slider 305, when safety pin 304 is inserted, slider 305 is in a specific position, and the position of cylindrical neodymium magnet 407 is relatively fixed. Consequently, the magnetic field strength and distribution characteristics detected by Hall effect sensor 406 exhibit a specific pattern. When safety pin 304 is removed, the position of slider 305 changes, and the magnetic field of cylindrical neodymium magnet 407 also changes, causing the electrical signal output by Hall effect sensor 406 to change accordingly. In this way, the system can accurately determine the insertion state of safety pin 304, providing a reliable basis for subsequent control operations.

[0043] In constructing the equipment's overall sealing system, we utilize a silicone grease hardening process for all static seals. The selected silicone grease exhibits excellent chemical stability and adhesion. After application to the static seals, it undergoes a specialized hardening process. By precisely controlling the temperature, humidity, and time parameters of the hardening process, the silicone grease forms a dense and tough sealing layer that adheres tightly to the sealing interface, effectively blocking the intrusion of moisture, dust, and impurities. This sealing method is not only simple to implement, but also provides a long-lasting and reliable sealing effect, providing long-term and stable protection for critical components within the equipment.

[0044] This device was designed with long-term use in mind, with a 10-year lifespan goal set. To achieve this goal, strict control was exercised over material selection, structural design, and manufacturing processes. Furthermore, the device achieves an IP68 protection rating, the highest international standard for dust and water resistance.

[0045] In terms of water resistance, the device has undergone rigorous testing and is proven to operate underwater at a depth of up to 1 meter. Whether briefly immersed in shallow water or used for extended periods in humid environments, the internal electronic and mechanical components are protected from moisture. The IP68 rating ensures complete protection against dust ingress, ensuring internal cleanliness even in dusty and harsh environments, preventing malfunctions caused by dust accumulation.

[0046] The equipment boasts excellent temperature adaptability, capable of operating normally in extreme temperatures ranging from -40°C to 85°C. In such low-temperature environments, key internal components, such as the -70°C low-temperature grease used in movable parts, play a vital role. This low-temperature grease, with its extremely low freezing point and excellent lubrication properties, maintains fluidity and lubricity even in extremely cold conditions of -70°C, ensuring smooth operation of moving parts and preventing component seizure or increased wear caused by low temperatures.

[0047] In high-temperature environments, the device effectively reduces internal temperatures through rational heat dissipation design and the use of high-temperature resistant materials. Furthermore, the silicone grease hardened seal maintains stable performance even at high temperatures, without softening or volatilizing, which could affect the sealing effect. This ensures reliable operation of the device even in high-temperature conditions.

[0048] The equipment utilizes a unique design of bulkhead-type wiring terminals, which isolate different wiring harnesses through the bulkhead, effectively preventing interference and short circuit risks. Inorganic mineral grease is injected into the wiring terminals. This grease has excellent insulating and antioxidant properties, providing long-term protection for the wiring terminals and preventing poor contact or electrical failures caused by oxidation and corrosion.

[0049] We carefully sourced high-quality oil seals and -70°C low-temperature grease for all moving parts within the equipment. These seals utilize advanced rubber materials and a sealing structure to effectively prevent grease leakage and the ingress of foreign matter, while ensuring the smooth rotation of moving parts. The low-temperature grease provides excellent lubrication for moving parts, reducing friction and wear and extending the life of the equipment.

[0050] Through the above series of carefully designed sealing, protection and lubrication measures, this equipment can maintain excellent performance and reliability in various harsh environments, meet the 10-year service life requirement, and provide users with stable and efficient services.

[0051] It should be noted that the rotation of motor 302 is actively controlled by wireless communication module 108. After motor 302 is started, it drives eccentric weight 303 to rotate. The special shape of eccentric weight 303 produces radial displacement, pushing slider 305 outward, compressing first spring 306 and driving safety pin 304 outward together, causing safety pin 304 to disengage from transmission rod 201, releasing the constraint on transmission rod 201 and facilitating subsequent unlocking of the locking assembly. When transmission rod 201 needs to be constrained again, motor 302 is controlled to reverse. Under the action of first spring 306, slider 305 and safety pin 304 are reset, and safety pin 304 is inserted into the interior of transmission rod 201. At this time, handle 103 cannot rotate, and the locking assembly cannot be opened.

[0052] To manually unlock the door in exceptional circumstances, insert the emergency key 104 into the connecting shaft 402. The first magnet 401 at the bottom of the key 104 pulls the rotating shaft 404 upward, tightly fitting it against the camshaft 405. Turning the emergency key 104 transmits power to the camshaft 405 through the rotating shaft 404, causing it to rotate. This rotation of the camshaft 405 changes its contact position with the slider 305, pushing it outward. This manually releases the constraint on the transmission rod 201 and subsequently unlocks the locking assembly.

[0053] When the workers underground need to open the main body in an emergency, they only need to manually pull the bottom plate 205 downward to release the keyway connection with the bottom of the transmission rod 201. Then they can freely rotate the bottom plate 205 and actively control the extension and retraction of the three cylindrical rods 207 to complete the opening of the main body.
