Description

Technical Field

[0001] This utility model relates to the field of intelligent manhole cover technology, and in particular to an intelligent manhole cover with a locking structure. Background Technology

[0002] With the acceleration of urbanization and the increasing demand for intelligent infrastructure, traditional manhole covers are gradually failing to meet the requirements of modern urban management due to their limited functionality and insufficient safety. Ordinary manhole covers typically use mechanical locks (such as spring locks and padlocks) or physical reinforcement structures, allowing only opening and closing via physical keys, lacking proactive protection capabilities. These 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 accidents of pedestrians falling into them. Furthermore, mechanical locks are easily pried open or technically unlocked, resulting in weak anti-theft performance. Management methods relying on manual inspections are not only inefficient but also unable to monitor the real-time status of manhole covers, leading to delayed emergency response.

[0003] To address these issues, smart manhole cover technology has emerged. Its core objective is to improve the anti-theft capabilities and maintenance efficiency of manhole covers through electronic and networked methods, with intelligent lock control being a key element. However, existing smart manhole cover solutions still have significant technical shortcomings. For example, some products only support Bluetooth or NFC near-field unlocking, failing to achieve remote authorization management, making it difficult for municipal departments to intervene quickly when manhole covers are stolen or require emergency repairs. While some solutions have electronic lock functions, they lack status monitoring modules, failing to detect in real time whether the manhole cover has been illegally opened, moved, or damaged, making it difficult to detect potential hazards in a timely manner. Furthermore, existing technologies generally suffer from a single unlocking method, relying solely on electronic systems without a physical emergency unlocking interface. If the electronic system malfunctions or the battery runs out, workers or trapped individuals working underground will face life-threatening situations because they cannot open the manhole cover. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides an intelligent manhole cover with a locking structure, which effectively solves the problems of existing manhole covers being unable to be remotely unlocked, lacking real-time monitoring of the manhole cover status and underground environment, having a single unlocking method, and lacking emergency unlocking guarantee.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model includes an intelligent manhole cover with a locking structure, comprising a cover plate, a housing at the bottom of the cover plate, an external manhole cover detection module, a battery, a wireless communication module and an antenna respectively disposed inside the housing, the battery being detachably connected to the housing, a sleeve in the middle of the housing, a limiting block at the top of the sleeve, a transmission rod in the middle of the limiting block, a handle at the top of the transmission rod, a base plate at the bottom of the transmission rod, and a locking component at the bottom of the base plate.

[0007] Preferably, a support block is provided on one side of the limiting block, a control component is provided inside the support block, a slider is provided in the middle of the control component, and a safety pin (304) is provided on the outer side of the slider, the safety pin cooperating with the transmission rod.

[0008] Preferably, a positioning pin is provided on one side of the transmission rod, and the outer side of the positioning pin is connected to the limiting block.

[0009] Preferably, the control component includes a motor, the outer side of which is connected to a support block, an eccentric block is provided on the top of the motor, the outer side of which is connected to a slider, and a first spring is provided at the rear end of the safety pin, the rear end of which abuts against the support block.

[0010] Preferably, the top of the slider is provided with a camshaft, the top of the camshaft is provided with a rotating shaft, the top of the rotating shaft is provided with a second spring, the top of the second spring is provided with a connecting shaft, and the connecting shaft is connected to the support block.

[0011] Preferably, an emergency unlocking key is fitted inside the connecting shaft, and a first magnet is provided at the bottom of the emergency unlocking key.

[0012] Preferably, the locking assembly includes multiple connecting rods, the outer end of each connecting rod is provided with a cylindrical rod, a positioning block is slidably connected to the outer side of the cylindrical rod, and the top of the positioning block is connected to the cover plate.

[0013] Preferably, a third spring is provided at the bottom of the transmission rod, and the top of the third spring abuts against the bottom of the base plate.

[0014] 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.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In special circumstances, the first magnet at the bottom of the emergency unlocking key is used to attract the rotating shaft upwards. The rotating shaft transmits power to the camshaft, pushing the slider to move outwards and manually releasing the constraint on the transmission rod. This provides a reliable solution for emergencies. Furthermore, the manual unlocking mechanism cannot be activated without the first magnet, thus improving the system's security.

[0017] 2. When underground workers need to open the well cover, they only need to manually pull the base plate downwards to release the keyway engagement with the bottom of the transmission rod. The base plate can then be rotated freely, and the extension and retraction of the three cylindrical rods can be actively controlled to open the main body, providing an emergency operation method for underground work.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 1-13 The specific embodiments of this utility model will be described in further detail.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Depend on Figures 1-13 This invention proposes an intelligent manhole cover with a locking structure:

[0035] This utility model includes a cover plate 101, which is made of high-strength composite material and coated with an anti-slip and wear-resistant coating. The bottom of the cover plate 101 is provided with a housing 105, which is a sealed and waterproof structure. Inside the housing 105, there are 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 housing 105. The external manhole cover detection module 102 adopts an anti-interference integrated design. Its bottom integrates a high-sensitivity micro switch. The top of the micro switch is connected to an adjustable extension rod by a threaded fastener. The end of the extension rod is nested with a high-elasticity spring ball. The spring ball is flexibly connected to the extension rod by a compression spring to form a dynamic adaptive structure. When the manhole cover shifts laterally or tilts due to external forces (such as being towed by a vehicle or pried by someone), it avoids the problem of traditional rigid structures being easily jammed or damaged by the manhole cover. The battery 106 adopts a modular quick-release design, and the built-in power monitoring chip can collect the remaining power, voltage and charging / discharging status in real time. The wireless communication module 108 integrates dual-mode communication capabilities, supports the insertion of a standard Nano-SIM card to achieve 4G / NB-IoT wide area network remote communication, can upload the manhole cover status, sensor data and abnormal alarms to the cloud platform in real time, and receive remote unlocking commands or firmware upgrade packages; the module also has a built-in Bluetooth 5.0 chip, which supports near-field communication. Maintenance personnel can configure parameters, debug equipment and authorize emergency unlocking within a 10-meter range through a mobile APP or handheld terminal. The two communication modes can be automatically switched to ensure the reliability of data transmission.

[0036] A sleeve 203 is provided in the middle of the housing 105, and a limiting block 202 is provided at the top of the sleeve 203. The sleeve 203 and the limiting block 202 are fixedly connected to the housing 105 to provide support for the transmission rod 201. The transmission rod 201 is provided in the middle of the limiting block 202. A handle 103 is provided at the top of the transmission rod 201. A base plate 205 is provided at the bottom of the transmission rod 201. The bottom of the base plate 205 is connected to the base plate 205 by a spline. A locking component is provided at the bottom of the base plate 205. The handle 103 drives the transmission rod 201 and the base plate 205 to rotate, thereby locking and unlocking the locking component.

[0037] A support block 301 is provided on one side of the limiting block 202. The bottom of the support block 301 is fixedly connected to the housing 105 to provide support for the control component. The control component is located inside the support block 301. A slider 305 is located in the middle of the control component. The control component can control the slider 305 to move actively. 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 to constrain the rotation of the transmission rod 201.

[0038] A positioning pin 204 is provided on one side of the transmission rod 201. The outer side of the positioning pin 204 is connected to the limiting block 202, forming a limiting structure. An arc-shaped groove is formed inside the transmission rod 201, which fits tightly with the positioning pin 204. When the transmission rod 201 rotates, the positioning pin 204 slides along the groove, precisely restricting its rotation to a range of 90 degrees.

[0039] The control assembly includes a motor 302, the outer side of which is connected to a support block 301. An eccentric block 303 is located on the top of the motor 302. The eccentric block 303 has a special shape, with its center of mass offset from the rotation center. The outer side of the eccentric block 303 is connected to a slider 305. A first spring 306 is located at the rear end of a safety pin 304. The rear end of the first spring 306 abuts against the support block 301. Under the action of the first spring 306, a continuous inward force is applied to the slider 305. Normally, the safety pin 304 is inserted into the transmission rod 201, preventing the transmission rod 201 from rotating. When the motor 302 starts rotating, it drives the eccentric block 303 to rotate as well. The rotation of handle 3, due to its unique shape, causes radial displacement, which in turn pushes slider 305 to move outward. When slider 305 moves, it compresses the first spring 306, and simultaneously drives safety pin 304 to move outward as well. At this time, safety pin 304 disengages from transmission rod 201, successfully releasing the constraint on transmission rod 201. When it is necessary to continue to constrain transmission rod 201, control motor 302 reverses. Under the action of the first spring 306, slider 305 and safety pin 304 actively reset, and safety pin 304 inserts into transmission rod 201. At this time, handle 103 cannot rotate. The rotation of motor 302 can be actively controlled through wireless communication module 108 to achieve active control.

[0040] The top of the slider 305 is equipped with a camshaft 405, the top of the camshaft 405 is equipped with a rotating shaft 404, the top of the rotating shaft 404 is equipped with a second spring 403, and the top of the second spring 403 is equipped with a connecting shaft 402. The connecting shaft 402 is connected to the support block 301. An emergency unlocking key 104 is fitted inside the connecting shaft 402. The bottom of the emergency unlocking key 104 is equipped with a first magnet 401. When manual unlocking is required in special circumstances, the emergency unlocking key 104 is inserted into the connecting shaft 402. The first magnet 401 will exert a strong attraction, firmly attracting the rotating shaft 404 upwards, so that the rotating shaft 404 and the camshaft 405 are tightly fitted. At this time, turning the emergency unlocking key 104 can accurately transmit power to the camshaft 405 through the rotating shaft 404, driving the camshaft 405 to rotate. The rotation of the camshaft 405 changes its contact position with the slider 305, thereby pushing the slider 305 to move outward, thus manually releasing the constraint on the transmission rod 201, allowing the system to return to normal operation or perform emergency operations. Without the attraction 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, while other components are made of aluminum, and are not attracted by the magnetic lock of the first magnet 401.

[0041] The locking assembly includes multiple connecting rods 206. The outer end of each connecting rod 206 is provided with a cylindrical rod 207. 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 shift outward. The connecting rods 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 to make the device body fixed and stable. Conversely, the device can be disassembled.

[0042] The bottom of the transmission rod 201 is equipped with a third spring 209. The top of the third spring 209 abuts against the bottom of the base plate 205. When the underground workers need to open the main body in an emergency, they only need to manually pull the base plate 205 downward to release the keyway engagement with the bottom of the transmission rod 201. Then, the base 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.

[0043] A cylindrical neodymium magnet 407 is mounted on the outer side of the slider 305, and a Hall sensor 406 is mounted on the outer side of the cylindrical neodymium magnet 407. The 2x3 high-temperature resistant cylindrical neodymium magnet 407 is a small-sized strong magnet, with a diameter of 2 mm and a height of 3 mm. The cylindrical neodymium magnet 407 is made of neodymium iron boron material and has high magnetic properties and high temperature resistance. These magnets are usually coated (such as nickel plating) to enhance their oxidation resistance and service life. Their operating temperature range is generally between 100℃ and 200℃, and some high-performance models can withstand higher temperatures. The Hall sensor 406 is securely mounted on a specially designed bracket. The bracket material has good rigidity and stability, which can ensure that the relative position between the Hall sensor 406 and the cylindrical neodymium magnet 407 remains unchanged. The Hall sensor 406 is a magnetically sensitive element based on the Hall effect. It is extremely sensitive to changes in magnetic fields and can accurately detect minute changes in the strength of the surrounding magnetic field. When the slider 305 moves, the cylindrical neodymium magnet 407 also moves, and the magnetic field distribution it generates changes. The Hall sensor 406 captures these magnetic field changes in real time and converts them into corresponding electrical signals. The control circuit receives these electrical signals and performs rapid analysis and processing. Since the insertion state of the safety pin 304 is closely related to the position of the slider 305, when the safety pin 304 is inserted, the slider 305 is in a specific position, and the position of the cylindrical neodymium magnet 407 is also relatively fixed. The magnetic field strength and distribution characteristics detected by the Hall sensor 406 will exhibit a specific pattern. When the safety pin 304 is pulled out, the position of the slider 305 changes, the magnetic field of the cylindrical neodymium magnet 407 changes accordingly, and the electrical signal output by the Hall sensor 406 will also change accordingly. In this way, the system can accurately determine the insertion state of the safety pin 304, providing a reliable basis for subsequent control operations.

[0044] In the overall sealing system construction of the equipment, we adopted a silicone grease curing sealing process for all static sealing locations. The selected silicone grease possesses excellent chemical stability and adhesion, and after being applied to the static sealing areas, it undergoes a special curing process. By precisely controlling the temperature, humidity, and time parameters during the curing process, the silicone grease forms a dense and tough sealing layer that adheres tightly to the sealing interface, effectively preventing the intrusion of external moisture, dust, and impurities. This sealing method is not only simple to apply but also provides a long-lasting and reliable sealing effect, offering long-term stable protection for critical internal components of the equipment.

[0045] This equipment was designed with long-term use in mind from the outset, with a target service life of 10 years. To achieve this, strict controls were implemented in material selection, structural design, and manufacturing processes. Furthermore, the equipment meets an IP68 protection rating, which is currently the highest international standard for dust and water resistance.

[0046] In terms of waterproofing, the equipment has undergone rigorous testing and can operate normally at a depth of 1 meter underwater. Whether briefly submerged in shallow water or used for extended periods in humid environments, it ensures that internal electronic components and mechanical parts are not corroded by moisture. Regarding dustproofing, the IP68 rating means the equipment is completely dustproof, maintaining internal cleanliness even in dusty and harsh environments, preventing equipment malfunctions caused by dust accumulation.

[0047] The equipment boasts excellent temperature adaptability, capable of operating normally within an extreme temperature range of -40℃ to 85℃. In low-temperature environments, critical internal components, such as the -70℃ cryogenic grease used in moving parts, play a vital role. This cryogenic grease has an extremely low freezing point and excellent lubrication properties, maintaining its fluidity and lubricity even at -70℃, ensuring smooth operation of moving parts and preventing jamming or accelerated wear due to low temperatures.

[0048] In high-temperature environments, the equipment effectively reduces internal temperature through a reasonable heat dissipation design and the selection of high-temperature resistant materials. Simultaneously, the silicone grease-cured sealing layer maintains stable performance at high temperatures, without softening or evaporation affecting the sealing effect, ensuring reliable operation of the equipment even under high-temperature conditions.

[0049] The equipment uses partition-type wire harness terminals. This unique terminal design isolates different wire harnesses through partitions, effectively avoiding mutual interference and short-circuit risks between wire harnesses. Inorganic mineral grease is injected inside the wire harness terminals. Inorganic mineral grease has excellent insulation and oxidation resistance properties, providing long-term protection for the wire harness terminals and preventing poor contact or electrical faults caused by oxidation, corrosion, etc.

[0050] For all moving parts in the equipment, we carefully sourced high-quality oil seals and -70°C cryogenic grease. The oil seals utilize advanced rubber materials and a sealing structure design to effectively prevent lubricant leakage and the ingress of external impurities, while ensuring smooth rotation of moving parts. The cryogenic grease provides excellent lubrication for the moving parts, reducing friction and wear, and extending the equipment's service life.

[0051] 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 requirement of 10 years of service life, and provide users with stable and efficient service.

[0052] It should be noted that the motor 302 is actively controlled by the wireless communication module 108. After the motor 302 starts, it drives the eccentric block 303 to rotate. The special shape of the eccentric block 303 causes radial displacement, pushing the slider 305 outward. This compresses the first spring 306 and causes the safety pin 304 to move outward as well, disengaging it from the transmission rod 201 and releasing the constraint on the transmission rod 201, facilitating subsequent unlocking of the locking assembly. When it is necessary to constrain the transmission rod 201 again, the motor 302 is reversed. Under the action of the first spring 306, the slider 305 and the safety pin 304 return to their original positions, and the safety pin 304 inserts into the transmission rod 201. At this time, the handle 103 cannot rotate, thus preventing the locking assembly from opening.

[0053] In special circumstances requiring manual unlocking, the emergency unlocking key 104 is inserted into the connecting shaft 402. The first magnet 401 at the bottom of the emergency unlocking key 104 attracts the rotating shaft 404 upwards, ensuring a tight fit between the rotating shaft 404 and the camshaft 405. Rotating the emergency unlocking key 104 transmits power to the camshaft 405 via the rotating shaft 404, causing the camshaft 405 to rotate. This rotation changes the contact position between the camshaft 405 and the slider 305, pushing the slider 305 outwards, manually releasing the constraint on the transmission rod 201, and subsequently unlocking the locking assembly.

[0054] 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 engagement 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.
