[0010] The cast aluminum trapezoidal housing uses a frosted aluminum frame as the main part of the housing, and has an overall trapezoidal structure with a mounting slot provided inside;

[0011] The upper end surface area of the trapezoidal structure is smaller than the lower end surface area. The trapezoidal structure has two opposite side surfaces, one pair of which is a smooth oblique side surface, and the other pair of side surfaces each has a mounting hole.

[0014] Specifically,

[0015] The monitoring device must be installed parallel to the manhole cover;

[0016] The monitoring device is installed in two ways: on the surface of the manhole cover and inside the manhole cover;

[0017] When the surface of the manhole cover is used, the monitoring device can be fixed on the manhole cover by passing bolts through the mounting holes or by gluing.

[0018] When adopting the method of internal installation of the manhole cover, the casting mold of the manhole cover needs to reserve a light-transmitting square hole the size of the solar panel of the monitoring device on the outside of the manhole cover, and reserve an installation compartment the size of the monitoring device inside, and ensure that the solar panel on the upper end surface of the monitoring device is on the same horizontal line as the outer surface of the manhole cover;

[0019] The sensors include a gas sensor, an acceleration sensor, a water immersion sensor and a light sensor; the sensors can be disassembled and replaced according to actual needs.

[0033] The monitoring device can monitor the temperature of the pipe gallery under the manhole cover in real time. If the temperature exceeds the set alarm temperature, it indicates that there is a fire hazard in the pipe gallery and an alarm is issued in time.

[0034] The further improvement of the present invention is:

[0035] The communication module uses wireless remote control to configure parameters and upgrade programs of the monitoring device.

[0036] The further improvement of the present invention is:

[0037] The antenna is embedded in the surface of the cast aluminum trapezoidal shell to avoid the problem of poor communication in the well.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] The utility model adopts a cast aluminum trapezoidal shell structure as the shell of the monitoring device, which has simple process and low cost, and has the structural characteristics of being resistant to heavy pressure, waterproof, moisture-proof, corrosion-resistant, and having a high wireless signal-to-noise ratio, and can adapt to a variety of harsh environments; and the edges are smooth and will not damage the tires of vehicles that have passed over them.

[0040] This utility model uses a solar power supply system. A solar panel is mounted on the upper end of the cast aluminum trapezoidal housing, ensuring that it draws as much solar energy as possible to charge the battery within the housing's mounting slot, thereby ensuring the normal operation of the entire monitoring device. This utility model eliminates the need for regular battery replacement, not only reducing waste and protecting the ecological environment, but also avoiding the significant labor and material resources required for frequent battery replacement, thus saving social resources.

[0041] The utility model fixes the warning light source on the smooth inclined side surface of the cast aluminum trapezoidal shell, thereby preventing the driver from having poor vision while driving at night and being unable to observe the safety hazards caused by missing or shifted manhole covers; and embeds the antenna on the surface of the cast aluminum trapezoidal shell to avoid the problem of poor communication inside the manhole.

[0042] In summary, the utility model has low manufacturing and maintenance costs, a simple structure, little loss of battery resources, a wide range of applications, and is easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention is described in further detail below with reference to the accompanying drawings:

[0047] like Figure 1 As shown, the present invention provides a solar-powered intelligent manhole cover monitoring device comprising a cast aluminum trapezoidal housing structure 1, a solar panel 2, a warning light or antenna 3, and a communication module. The cast aluminum trapezoidal housing 1 uses a frosted aluminum frame as the main part of the housing, and has an overall trapezoidal structure with mounting slots provided inside. The upper end surface area of the trapezoidal structure is smaller than the lower end surface area. The trapezoidal structure has two opposing side surfaces, one pair of which is a smooth, oblique side surface 3, and the other pair of side surfaces each having a mounting hole 4. The monitoring device is equipped with a built-in power supply battery and a main circuit board for communication data acquisition.

[0048] The solar panel 2 is fixed on the upper end surface of the cast aluminum trapezoidal shell, the rechargeable battery, sensor and communication module are encapsulated in the mounting groove of the cast aluminum trapezoidal shell 1, and the warning light source and antenna are fixed on the smooth inclined side surface 3 of the cast aluminum trapezoidal shell; the lower end surface of the cast aluminum trapezoidal shell serves as the mounting surface of the monitoring device.

[0049] The present invention provides a solar-powered intelligent manhole cover monitoring device according to an embodiment of the present invention.

[0050] [Example 1]

[0051] like Figure 1 As shown, the present invention utilizes a solar power system to power the entire device. Specifically, the entire device utilizes a cast aluminum trapezoidal shell structure, which is resistant to heavy pressure, water, moisture, and corrosion, and boasts a high wireless signal-to-noise ratio. This structural feature allows it to adapt to harsh environments such as sewage and rainwater networks, which are confined, humid, prone to corrosion, and prone to flooding. Solar panels are used to charge the rechargeable batteries within the mounting slots, meeting the needs of long-term online monitoring, avoiding unnecessary battery loss and reducing maintenance costs.

[0052] Furthermore, the mounting grooves for encapsulating batteries, communication modules, and sensors are sealed to form a closed inner cavity that is corrosion-resistant and meets waterproof standards, thereby avoiding losses caused by frequent exposure of circuits to the external environment and reducing maintenance costs.

[0053] The utility model can realize the safety management of manhole covers, the census of ownership and the monitoring of fire hazards in underground pipe corridors. At the same time, the built-in three-axis acceleration chip realizes real-time monitoring of the manhole cover posture and uploads it to the user end in time.

[0054] By integrating a solar power supply system, a charging voltage boost module, a wireless data transmission module (DTU), and manhole covers, this new system effectively helps cities achieve unified management of manhole covers, enabling remote monitoring, intelligent control, and anti-theft measures. This system promotes solutions to urban infrastructure issues, facilitates dynamic, closed-loop, and long-term management of manhole covers, and lays the foundation for industry applications in smart cities.

[0055] [Example 2]

[0056] When installing the manhole cover monitoring device, two methods can be used, either surface-mounted or internally mounted, depending on the actual application environment. Before installing the manhole cover monitoring device, attention should be paid to whether there is any interference at the installation site and whether the cast aluminum trapezoidal housing 1 is installed horizontally, so that the device and the manhole cover are always in a relatively parallel and stable state.

[0057] For example, the present invention provides two installation solutions, specifically:

[0058] like Figure 2 When the monitoring device is installed on the surface of the manhole cover, the determined installation point should be firm and reliable, and the bolts should be passed through the installation holes 4 to fix it on the manhole cover. The installation should be firm to prevent it from shaking; or the monitoring device can be fixed on the manhole cover by gluing.

[0059] like Figure 3 When installing inside the manhole cover, it is necessary to reserve an installation compartment of the size of the monitoring device inside the manhole cover when casting the manhole cover, and ensure that the solar panel 2 on the upper end face of the monitoring device is at the same level as the manhole cover surface.

[0060] The utility model also provides an installation method and precautions for a solar-powered intelligent manhole cover monitoring device. When the manhole cover monitoring device needs to be installed on a manhole cover where the operator base station signal is poor, the communication antenna is embedded in the surface of the cast aluminum trapezoidal shell on the premise of ensuring that the monitoring device is installed and fixed reliably to avoid the problem of poor communication in the well.

[0061] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0062] In the description of the present invention, unless otherwise specified, the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0063] The above technical solution is only one implementation method of the present invention. For those skilled in the art, it is easy to make various types of improvements or modifications based on the principles disclosed in the present invention, and it is not limited to the structure described in the above specific embodiments of the present invention. Therefore, the above description is only preferred and does not have a restrictive meaning.
