Description

Technical Field

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

[0002] Manhole covers are closures at the top of entrances and exits leading to underground facilities. They play a vital role in urban infrastructure. Smart glass manhole covers play an important role in improving the safety and management efficiency of urban infrastructure, enhancing urban aesthetics and citizen experience, and promoting sustainable urban development. With the continuous advancement of technology and the in-depth promotion of its application, smart glass manhole covers will play a more important role in future urban construction.

[0003] In municipal engineering, glass manhole covers are often used as isolation devices between sidewalks and roadways, which not only ensures the safety of pedestrians and vehicles, but also facilitates the inspection and maintenance of underground pipelines. In vertical shaft facilities such as urban sewers and septic tanks, due to the decomposition and fermentation of organic metabolites by microorganisms, a flammable and explosive mixed gas - biogas will be produced. About 70% of the components in biogas are methane, which can burn in the air and is a clean energy source. Under normal circumstances, these gases should be discharged through exhaust holes and other facilities to prevent accumulation. However, if the exhaust is not smooth or the exhaust holes are blocked, the gas will accumulate in the well. When the combustible gas accumulated in the well reaches a certain concentration, it will cause an explosion when it encounters open flames or high temperatures (such as open flame operations, cigarette butts, static sparks, etc. during construction). The huge impact force generated by the explosion will lift the manhole cover as a whole, or the tempered glass will break, and even cause more serious consequences, such as casualties, property losses, etc., and the existing manhole covers have not made perfect emergency plans and other measures for such safety hazards in actual use, resulting in serious safety hazards when they are used. Summary of the invention

DETAILED DESCRIPTION

[0042] 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 implementation regulations 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.

[0043] Embodiment 1, refer to Figure 1-Figure 11 As shown: The present invention provides an intelligent glass manhole cover, comprising:

[0044] The external mechanism 1 is used to install the main mechanism 2 inside itself and maintain the stability of the main mechanism 2;

[0045] The main body 2 is used to achieve its own stable connection and facilitate its own disassembly, providing good adjustment conditions for its own stability;

[0046] The clamping mechanism 3, driven by the built-in motor 23, can drive the various components inside the clamping mechanism 3 to achieve transmission, and the two sets of limit blocks 321 can be clamped inside the locking groove 111, so as to achieve the mutual embedding and clamping of the overall device and the concrete layer 11, so as to maintain the stability of the device;

[0047] The detection mechanism 4 acts on the various air pressures in the detection well. When the pressure value is at a high level, it can squeeze the various components inside the detection mechanism 4 to transmit and form instructions, thereby transmitting the instructions to the inside of the controller to start and shut down the built-in motor 23.

[0048] In this embodiment, when the driving rod A232 starts to rotate, it effectively drives the driving rod B331, thereby prompting the spur gear A333 to rotate smoothly in the rotating frame 33. This rotation action is not limited to the spur gear A333 itself, but also drives the synchronous rotation of the two spur gears B34 through its outer wall fixedly connected to the two spur gears B34. The two sets of bearings B342 play a key role in this process, ensuring that the two threaded rods 341 can rotate freely and stably. As the threaded rods 341 rotate, their outer surfaces are closely matched with the threaded structure inside the linkage plate 32, resulting in an efficient thread transmission effect. This transmission mechanism is further strengthened with the assistance of the two sets of slide plates 322. 22 are respectively slidably embedded in the sliding groove 212, and the linkage plate 32 is slidably embedded in the inner sliding groove 311 through a slide bar. The two together ensure the stability and accuracy of the linkage plate 32 during the movement. Under the dual effects of threaded transmission and sliding embedding, the two linkage plates 32 begin to move to both sides respectively. As they gradually approach the inner wall of the concrete layer 11, they finally achieve close contact with the inner wall. At this time, the two sets of limit blocks 321 are accurately embedded in the locking groove 111 pre-set in the concrete layer 11, thereby firmly connecting the equipment to the concrete layer 11, realizing the overall reinforcement and stability of the equipment. This design not only enhances the safety of the equipment, but also improves its ability to cope with various complex environments.

[0051] The clamping mechanism 3 includes two fixing frames 31 and a rotating frame 33;

[0052] A set of inner slide grooves 311 are preset inside the two fixing frames 31, and the inner surface walls of the two sets of inner slide grooves 311 are slidably embedded with linkage plates 32 through slide bars, and the tops of the two linkage plates 32 are fixedly connected with a set of limit blocks 321, and one side of the outer walls of the two linkage plates 32 is fixedly connected with a set of limit blocks 321;

[0053] The interior of the rotating frame 33 is rotatably connected with a driving rod B331, and one side of the outer wall of the two fixed frames 31 is fixedly installed with the outer wall of the rotating frame 33. A slot 332 is provided at the top of the driving rod B331, and a spur gear A333 is fixedly connected to the bottom of the driving rod B331.

The staff uses an external specific tool to clamp it on the top of the adjustment damper 222 and rotate it.

When the two are locked, the clamping plate 233 can be clamped in the inside of the clamping groove 332, so as to realize the transmission relationship between the driving rod A232 and the driving rod B331.

[0057] Two holes 211 are provided on the outer wall of the manhole cover outer frame 21, a group of sliding grooves 212 are provided at the bottom of the manhole cover outer frame 21, and the outer walls of the two groups of slide plates 322 are slidably embedded in the inside of the group of sliding grooves 212, one side of the outer wall of the manhole cover outer frame 21 is fixedly connected to two hinges 22, a glass manhole cover 221 is fixedly connected between the adjustment ends of the two hinges 22, two adjustment dampers 222 are fixedly inserted inside the glass manhole cover 221, and the adjustment ends of the two adjustment dampers 222 are fixedly sleeved with limit plates 223, one side of the outer wall of the glass manhole cover 221 is provided with a fixing groove 224, a built-in motor 23 is fixedly inserted inside the fixing groove 224, and a flat gear 231 is fixedly connected to the rotating end of the built-in motor 23, and the flat gear 231 A driving rod A232 is fixedly inserted at the center of one side of the outer wall, and a card plate 233 is fixedly connected to one side of the outer wall of the driving rod A232, and the outer wall of the card plate 233 is movably embedded in the inner part of the card slot 332. Two connecting plates 24 are fixedly installed on one side of the outer wall of the glass well cover 221, and two groups of moving grooves 251 are preset inside the adjustment frame 25, and one side of the outer wall of the two groups of connecting plates 24 is fixedly connected to one side of the outer wall of the adjustment frame 25, and moving bars 252 are slidably embedded inside the two groups of moving grooves 251, and an extension plate 253 is fixedly installed between the outer walls of the two groups of moving bars 252, and a group of tooth grooves 254 are opened on one side of the inner wall of the two extension plates 253, and the outer wall of the flat gear 231 is meshed with the inside of the two groups of tooth grooves 254;

[0058] The detection mechanism 4 includes a fixing plate 41 and a limit adjustment rod 47;

[0059] A group of notches 411 are provided at the top of the fixed plate 41, a rotating groove 412 is provided at the bottom of the fixed plate 41, a driving seat 42 is provided at the inner center of the fixed plate 41, and the outer wall of the linkage rod 35 is fixedly inserted in the driving seat 42, a group of sealing sheets 421 are fixedly connected to the outer wall of the driving seat 42, a group of telescopic frames 43 are slidably embedded in the inner wall of the rotating groove 412 through a slide bar, a filter plate 44 is fixedly connected between the bottoms of a group of telescopic frames 43, an electrode A45 is fixedly connected at the bottom center of the fixed plate 41, an electrode B46 is fixedly connected at the top center of the filter plate 44, and a limiting groove 422 is provided at the bottom of the driving seat 42;

[0060] A spring 48 is movably sleeved on the outer wall of the limit adjustment rod 47 , and the outer wall of the spring 48 is in contact with the top of the filter plate 44 and the bottom of the fixed plate 41 .

[0061] In this embodiment, when the detection is carried out in the well, due to the large amount of combustible gas accumulated in the well, when encountering high temperature and explosion shock, the generated air pressure will impact the detection mechanism 4, and the air pressure will quickly impact the filter plate 44 at the bottom of the detection mechanism 4. At this time, the limit adjustment rod 47 can be embedded and moved up and down inside the limit groove 422, and the four telescopic frames 43 can cooperate with this up and down adjustment. When the impact force reaches a certain level, the elasticity generated by the spring 48 inside it is less than the force brought by the impact, and the bottom electrode B46 can be kept in contact with the electrode A45, thereby forming a closed circuit, so that the external circuit can be transmitted to the inside of the built-in motor 23, and a series of subsequent operations can be completed.

[0062] The working principle of the entire mechanism is as follows: during the equipment installation process, the first and most critical step is to accurately place the manhole cover frame 21 on the manhole mouth to ensure that its top is perfectly flush with the surrounding ground. Then, two carefully designed hinges 22 are used as rotating hubs to support the glass manhole cover 221 to achieve smooth and unimpeded opening and closing operations. With the help of special tools, the staff carefully adjusts the damper 222, and the rotating mechanism at the bottom drives the limit plate 223 to rotate and tightly lock to the bottom of the manhole cover frame 21, thereby firmly connecting the glass manhole cover 221 and the manhole cover frame 21. Once the two are firmly locked, the bottom card plate 233 will be accurately embedded in the card slot 332, constructing a stable and reliable transmission body between the driving rod A232 and the driving rod B331. In order to comprehensively monitor the safety conditions in the well, we have specially deployed a detection mechanism 4 and integrated a biogas concentration monitoring device at its bottom. Relying on advanced means such as Internet of Things technology and data analysis, the system can monitor the state of the well cover and the environment in the well (including changes in the position of the well cover, changes in biogas concentration, etc.) in real time. Once an abnormal situation is found, an alarm message will be immediately sent to the management personnel or relevant departments through the wireless network. This system not only supports remote monitoring and fault diagnosis, but also gives the management personnel the ability to remotely control the opening or closing of the well cover, greatly improving the intelligence level of the equipment. In view of the fact that flammable and explosive gases may accumulate in the well, we have specially added a filter plate 44 as a safety barrier to deal with potential explosion shocks. When the shock occurs, the air pressure quickly acts on the detection mechanism 4 and the filter plate 44, triggering a series of precise mechanical reactions: the limit adjustment rod 47 moves flexibly in the limit groove 422, and the four telescopic frames 43 work together to effectively absorb the impact energy. If the impact intensity exceeds the buffering range of the spring 48, the electrode B46 will contact the electrode A45 to activate the built-in motor 23. After the motor is started, the magnetic field drives the rotor to rotate, thereby driving the flat gear 231 to rotate in the adjustment frame 25, tightly meshing with the tooth groove 254, pushing the two extension plates 253 to stretch to both ends and firmly fit into the hole 211, further strengthening the connection between the manhole cover and the manhole cover outer frame 21. At the same time, the rotation of the driving rod A232 will drive the driving rod B331 and the spur gear A333 to rotate in the rotating frame 33, thereby driving the spur gear B34 and The threaded rod 341 rotates, and the threaded rod 341 and the threaded structure inside the linkage plate 32 are closely matched. In addition, the sliding plate 322 slides smoothly in the sliding groove 212 and the inner sliding groove 311, pushing the linkage plate 32 to expand to both sides until it is tightly fitted with the inner wall of the concrete layer 11, and the limit block 321 is embedded in the locking groove 111 to achieve a stable connection between the equipment and the concrete layer 11. In addition, the linkage rod 35 rotates with the spur gear A333, driving the drive seat 42 and the sealing plate 421 to rotate to a position aligned with the notch 411, providing preliminary resistance to air pressure shock. When the electrode A45 and the electrode B46 are in a separated state for a long time, the built-in motor 23 will automatically rotate in the opposite direction to restore all components to the initial state. At this time, the sealing plate 421 is misaligned with the notch 411.Ensure that the gas in the well can flow smoothly and maintain the natural balance of the well environment.

[0063] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
