Description

Technical Field

[0001] This utility model relates to the technical field of manhole covers, and in particular to an anti-settlement smart manhole cover with adjustable load. Background Technology

[0002] Manhole covers are an indispensable component of urban infrastructure, widely used in inspection wells for municipal, power, and communication pipelines. Traditional manhole covers are usually placed directly on the support surface of the manhole casing or connected by simple hinges.

[0003] Under the impact of long-term vehicle loads, the asphalt concrete foundation around the manhole cover is prone to plastic deformation and compaction settlement, resulting in a height difference between the manhole cover and the road surface, causing "bounce" phenomenon and noise, posing a traffic safety hazard. Existing technology, such as patent publication number CN218405560U, discloses an adjustable manhole cover, including a manhole base, a manhole casing, a worm gear, a double-acting screw, a support column, two nut seats, and two support blocks. The manhole base has a manhole cover body with mounting holes, and the manhole casing is fixed to the bottom of the manhole base. The worm gear is installed in the mounting holes, and a support seat is fixed to the side wall of the manhole casing, with the bottom of the worm gear rotatably connected to the support seat. The double-acting screw is horizontally installed inside the manhole casing, with both ends rotatably connected to the side walls of the manhole casing, and a worm wheel is fixedly fitted onto the double-acting screw. The support column is horizontally mounted and fixed inside the manhole casing. Two nut seats are fitted onto the sides of the double-acting screw and the support column. Two support blocks are correspondingly installed on the top of the two nut seats, and each support block has a wedge-shaped groove on its top surface. Support rods are fixed to the bottom sides of the manhole cover body, with the lower ends of the two support rods corresponding to the bottom of the two wedge-shaped grooves.

[0004] The shortcomings of existing patented technologies are that the height adjustment of manhole covers can only be carried out after maintenance personnel discover that the manhole cover has settled. Since manhole covers are located all over the city, manually adjusting the height of manhole covers not only increases the labor intensity of maintenance personnel, but also cannot adjust the height of manhole covers in a timely manner, affecting traffic safety. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a load-adjustable anti-settlement smart manhole cover. The settlement monitoring module detects the settlement of the manhole cover body. When the settlement reaches the threshold, the height adjustment mechanism is activated. The height adjustment mechanism can adjust the height of the manhole cover body to make it perfectly flush with the surrounding road surface. No manual monitoring or adjustment is required. The manhole cover can be quickly and conveniently raised to a new height, which significantly reduces maintenance costs and traffic impact.

[0020] 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 scope of protection of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0023] Reference Figures 1-4 This utility model discloses a load-adjustable anti-settlement smart manhole cover, including a manhole cylinder 1 fixedly installed on the manhole wall, an adjusting ring 2, a manhole cover body 3 detachably connected to the top of the adjusting ring 2, and a washer 4 detachably connected between the manhole cover body 3 and the adjusting ring 2. The washer 4 can be made of high polymer elastic materials such as rubber and polyurethane. A height adjustment mechanism is provided between the manhole cylinder 1 and the adjusting ring 2. It also includes a settlement monitoring module, which is electrically connected to the height adjustment mechanism.

[0024] Using the above structure, the manhole cover body 3 and the adjusting ring 2 can be disassembled to replace the washer 4. By replacing the elastic washer 4 with one of different stiffness (Shore hardness), the stiffness and load-bearing capacity of the entire manhole cover system can be finely adjusted to adapt to the load requirements of different road grades. For example, in high-load scenarios (such as highways), a high-stiffness washer is selected, resulting in less system deformation, stronger load-bearing capacity, and direct response; in low-load scenarios (such as residential roads), a lower-stiffness washer is selected, resulting in better system buffering and better vibration and noise reduction. The settlement monitoring module detects the settlement of the manhole cover body 3. When the settlement reaches the threshold, the height adjustment mechanism is activated. The height adjustment mechanism can adjust the height of the manhole cover body 3 to make it perfectly flush with the surrounding road surface. No manual monitoring or adjustment is required, and the manhole cover can be quickly and conveniently raised to a new height, significantly reducing maintenance costs and traffic impact.

[0025] In detail, in this embodiment, the height adjustment mechanism includes an electric telescopic rod 5. A support part is fixed to the inner wall of the well shaft 1, and the electric telescopic rod 5 is fixed to the support part. A pressure block 7 that fits against the bottom of the adjusting ring 2 is fixed to the output end of the electric telescopic rod 5. The electric telescopic rod 5 adopts an existing product. By controlling the extension or shortening of the output end of the electric telescopic rod 5, the pressure block 7 can be driven to adjust the height of the adjusting ring 2. The support part adopts a support ring 6, which is fixed to the inner wall of the well shaft 1. A corrugated pipe 8 is connected between the adjusting ring 2 and the support ring 6. The electric telescopic rod 5 is used as the structure for adjusting the height of the pressure block 7. The corrugated pipe 8 can be installed. The corrugated pipe 8 can protect the telescopic end of the electric telescopic rod 5 and the pressure block 7. The electric telescopic rod 5 can be installed in its own protective shell to prevent the well environment from affecting the service life of the electric telescopic rod 5 and the pressure block 7.

[0026] In detail, in this embodiment, the settlement monitoring module includes a control box 9 fixed to the bottom of the manhole cover body 3. The control box 9 houses a main controller 10, a GNSS receiver 11, a GNSS antenna 12, a communication module 13, and a power supply module 14. The GNSS antenna 12 is connected to the GNSS receiver 11, and the electric telescopic rod 5, GNSS receiver 11, communication module 13, and power supply module 14 are electrically connected to the main controller 10. The GNSS antenna 12 and GNSS receiver 11 receive BeiDou satellite signals in real time. The received BeiDou satellite signals are processed by the main controller 10 and then transmitted to the cloud management platform for calculation via the communication module 13. The cloud management platform calculates the three-dimensional coordinates, and the changes in the three-dimensional coordinates determine whether the manhole cover body 3 has settled. The control box 9 in this invention is made of aluminum alloy and has a waterproof rating of IP67. The communication module 13 uses NB-IoT, LoRa, or 4G / 5G communication modules for data interaction with the cloud management platform. The power supply module 14 can be connected to mains power or solar power.

[0027] In detail, in this embodiment, the top of the adjusting ring 2 is provided with a bolt 18 that penetrates the manhole cover body 3, and the manhole cover body 3 is connected to the top of the bolt 18 by a nut 19; the connection between the manhole cover body 3 and the adjusting ring 2 can be ensured by the nut 19 and the bolt 18; the adjusting ring 2 is connected to the manhole barrel 1 by an anti-rotation pin 20; the anti-rotation pin 20 is provided to prevent the adjusting ring 2 from rotating during the adjustment process.

[0028] In detail, in this embodiment, the bottom of the manhole cover body 3 extends downward with a positioning flange 21, and the top of the adjusting ring 2 is provided with a positioning step 22 that is adapted to the positioning flange 21. The positioning flange 21 is embedded in the positioning step 22 to achieve radial limiting of the adjusting ring 2; this ensures that the manhole cover body 3 will not shift or make abnormal noise under vehicle impact, thus improving driving comfort and safety.

[0029] Example 2 Reference Figures 1-4 Based on the same concept as in Embodiment 1, this load-adjustable anti-settlement smart manhole cover also includes a pressure sensor 15 on the top of the pressure block 7, which is electrically connected to the main controller 10. The pressure sensor 15 is used to measure the static and dynamic pressure borne by the pressure block 7; the main controller 10 can transmit the data monitored by the pressure sensor 15 to the cloud management platform through the communication module 13; the cloud management platform can continuously monitor the load data; when the load is detected to exceed the preset threshold for a long period of time (such as on road sections with frequent heavy-load vehicles), the platform can issue an early warning, prompting management personnel to take intervention measures, such as: strengthening traffic control on the road section, maintaining the manhole cover, or even replacing its mechanical parts (such as elastic washers) with a higher-grade type, to achieve "load adjustment".

[0030] In detail, this embodiment also includes a water level sensor 16 and a gas sensor 17 installed on the well shaft 1. The water level sensor 16 and the gas sensor 17 are electrically connected to the main controller 10. The water level sensor 16 and the gas sensor 17 are led out to the main controller 10 through corrosion-resistant waterproof cables. The main controller 10 can exchange data monitored by the water level sensor 16 and the gas sensor 17 with the cloud management platform through the communication module 13. Among them, the pressure sensor 15, the water level sensor 16, and the gas sensor 17 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the functions of this application, so they will not be described in detail. The control circuit of the main controller 10 can be implemented by those skilled in the art through simple programming. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0031] Working principle: Step 1: Place the adjusting ring 2 inside the well shaft 1, and then connect the well cover body 3 to the adjusting ring 2. Adjust the height of the well cover body 3 according to the actual situation. Step 2: Receive Beidou satellite signals in real time through GNSS antenna 12 and GNSS receiver 11. Based on the changes in three-dimensional coordinates, it can be determined whether the monitoring manhole cover body 3 has settled. If the settlement reaches the threshold, control the output end of the electric telescopic rod 5 to extend, driving the pressure block 7 to adjust the height of the adjusting ring 2 so that it is perfectly flush with the surrounding road surface. Step 3: Pressure sensor 15 is used to measure the static and dynamic pressure borne by the pressure block 7. The cloud management platform can continuously monitor the load data. When the load is detected to exceed the preset threshold for a long period of time (such as on road sections with frequent heavy vehicles), the platform can issue an early warning to prompt the management personnel to take intervention measures. By replacing the elastic washers 4 with different stiffness (Shore hardness), the stiffness and load-bearing capacity of the manhole cover system can be finely adjusted to adapt to the load requirements of different road grades.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
