Description

Technical Field

[0001] This utility model belongs to the field of municipal facilities technology, and in particular relates to a manhole cover structure with a hanging-type intelligent inner manhole cover with ring. Background Technology

[0002] In existing technology, ductile iron manhole covers for general outdoor roads are installed in motor vehicle lanes, non-motor vehicle lanes, residential areas, or green belts, meeting the national standard GB / T 23858-2009 standards D400, C250, B125, or A15. These manhole covers are generally ordinary cast iron or fiberglass plastic manhole covers, and are managed separately by different departments such as municipal, water, electricity, and telecommunications.

[0003] For ductile iron manhole covers already in use, problems such as damage and loss often occur due to the use of inferior materials and substandard design, sometimes even leading to personal injury accidents. Especially during heavy rains and floods, detachable manhole covers are easily washed away by floodwaters, creating dangerous holes (manholes) in the road surface, which can be extremely dangerous for people or vehicles to fall into.

[0004] Most existing outdoor manhole covers do not contain intelligent monitoring equipment or locks. Especially for users in the telecommunications industry, the manholes beneath these covers often require the installation of numerous cables and fiber optic cables. This makes these covers easily vulnerable to being pried open by unauthorized individuals to steal cables and other illicit activities, potentially damaging the manhole cover facilities.

[0005] Given the various problems with ordinary manhole covers, it is necessary to install smart manhole covers in existing or newly built manholes. Utility Model Content

[0022] like Figure 1-3 As shown, a manhole cover structure with a hanging-type intelligent inner manhole cover includes: an outer manhole cover 1 and an outer manhole ring 2, which are hinged together by a hinge 15. An inner manhole ring 3 is installed on the inner side of the outer manhole ring 2, and an inner manhole cover 4 is supported on the inner manhole ring 3. The bottom of the inner manhole cover 4 has an inner manhole cover intelligent lock 8, and the bottom of the inner manhole cover intelligent lock 8 has a locking tongue 9. The locking tongue 9 enters or leaves the vertical projection area of ​​the inner manhole ring 3 during rotation to achieve locking or unlocking. The inner manhole cover intelligent lock 8 is used in conjunction with an intelligent key. The bottom of the inner manhole cover 4 has one or more tail hooks 10 on the side away from the inner manhole cover intelligent lock 8, and the end of the tail hook 10 extends into the vertical projection area of ​​the inner manhole ring 3.

[0023] It should be noted that during installation, first lift the inner manhole cover 4 above the inner manhole ring 3, tilting the tail hook 10 downwards and inserting it below the inner manhole ring 3, then flatten the inner manhole cover 4. Insert the smart key into the inner manhole cover smart lock 8, and then turn the key to operate the locking tongue 9, thereby achieving the locking action. Conversely, turning the key will unlock the manhole cover. In a preferred embodiment of this utility model, the bottom of the inner manhole cover 4 has an installation compartment 11, and an intelligent control module 13 is installed in the installation compartment 11. The intelligent control module 13 is electrically connected to the inner manhole cover smart lock 8, and the intelligent control module 13 is powered by a power supply module 12 installed in the installation compartment 11.

[0024] In a preferred embodiment of this utility model, an antenna box 7 is provided on the surface of the inner manhole cover 4. The antenna box 7 is electrically connected to the intelligent control module 13 and can transmit data through wireless transmission methods such as NB-IoT or 4G wireless network.

[0025] In a preferred embodiment of this utility model, a plurality of outer well ring lugs 201 are provided at the overlapping parts of the outer well ring 2 and the inner well ring 3. The inner well ring 3 has an inner well ring mounting hole 301 at the position corresponding to the outer well ring lugs 201. The inner well ring mounting hole 301 is fitted with the outer well ring lugs 201 for installation. Fastening bolts are installed on the outer well ring lugs 201.

[0026] In a preferred embodiment of this utility model, the inner well ring 3 is a two-section structure with a gap between the two sections, which allows for a certain amount of assembly space, typically 2 centimeters.

[0027] In a preferred embodiment of this utility model, the inner manhole cover 4 is provided with a plurality of manhole cover handles 6 on its surface, which facilitates the installation and removal of the manhole cover.

[0028] In a preferred embodiment of this utility model, a nameplate 5 is provided on the surface of the inner manhole cover 4.

[0029] In a preferred embodiment of this utility model, there are two tail hooks 10. The two tail hooks 10 are symmetrically arranged with the diameter passing through the center point of the inner manhole cover smart lock 8 as the axis of symmetry. The included angle between the two tail hooks 10 is usually 30-60 degrees.

[0030] It should be noted that the above structure can be newly constructed. In some cases, we may encounter special manholes where the cast iron manhole ring (outer manhole ring 2) has several ears (ears 201) originally used for installing fall protection nets. When installing the inner manhole cover 4, we can use these ears to install the inner manhole ring 3, thus facilitating the subsequent installation of the inner manhole cover 4. Generally, the installed inner manhole ring 3 and the installed inner manhole cover 4 are an integrated device, much like a security door in our home; once locked, it is difficult to open. It can only be opened using specific methods, such as unlocking via Bluetooth with a mobile phone, remote control unlocking, or emergency key unlocking. Since the smart manhole cover is equipped with a smart control module 13 that can transmit signals to the outside world through the antenna box 7, the status and movement of the manhole cover can be monitored on a computer platform. The control of the inner manhole cover smart lock 8 can utilize existing technology and is not limited here, as long as the setting of the inner manhole cover 3 is implemented through the structure of this application.
