Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, and in particular to an Internet of Things smart manhole cover. Background Art

[0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipes, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground at every section. The section from the pipeline to the ground is called a manhole. The manhole mouth is usually flush with the ground, so a cover is needed. The cover used to cover the manhole is called a manhole cover.

[0003] With regard to the existing related technologies, the inventors believe that the following defects often exist: the existing manhole covers are connected to the base through a rotating shaft, and the bottom of the manhole cover is covered on the top of the base, and the manhole cover is not fixed. When a heavy object passes above, the manhole cover will be rolled up, and the violent vibration generated when it falls will cause damage to the electronic components in the networking module, affecting the service life of the networking module. Utility Model Content

[0004] The technical problem to be solved by the utility model is that: the existing technology has the disadvantage that there is no limit on the upward movement of the manhole cover, and the rolling of heavy objects will cause the manhole cover to tilt up. For this reason, we propose an Internet of Things smart manhole cover.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: an IoT smart manhole cover, comprising a base, the interior of the base is rotatably connected to a manhole cover body through a rotating shaft, the top of the manhole cover body is provided with a cover opening hole, a networking module is installed at the bottom of the base, a storage groove is provided at the bottom of the base, a limiting plate is slidably connected to the interior of the storage groove, a limiting groove is provided at the bottom of the base, and a handle is fixedly connected to the top of the limiting plate.

[0006] Preferably, a thrust spring is fixedly connected to the rear end of the limiting plate, and the rear end of the thrust spring is fixedly connected to the rear end inside the receiving groove.

[0007] Preferably, both sides of the storage groove are provided with limiting sliding grooves, and both sides of the limiting plate are fixedly connected with limiting sliding blocks.

[0008] Preferably, placement grooves are provided on both sides of the storage groove, and the interior of the placement grooves is slidably connected to limit blocks.

[0009] Preferably, a return spring is fixedly connected to the rear end of the limit block, and the rear end of the return spring is fixedly connected to the rear end inside the placement groove.

[0010] Preferably, the bottom of the base is rotatably connected to four connecting rods via a rotating shaft, the interior of the connecting rods is fixedly connected to a limiting rod, and the top of the limiting rod is in contact with the bottom of the networking module.

[0011] Preferably, a tension spring is fixedly connected to the opposite surface of the connecting rod.

[0012] Technical effects and advantages of the utility model:

[0013] In the utility model, after the user covers the manhole cover body, he moves the handle to drive the limit plate at the bottom to enter the limit groove, so that the limit plate limits the upward movement of the manhole cover body. This can prevent the manhole cover body from being crushed when the vehicle passes by, causing the manhole cover body to tilt upward and generate violent vibrations, causing damage to the networking module at the bottom of the manhole cover body, thereby affecting the service life of the networking module.

[0014] In the utility model, when the user needs to maintain the networking module, the user pulls the handle backward to release the limit on the manhole cover body, so that the manhole cover body can be opened upward, and after opening the manhole cover body, the limit rods are moved to both sides to release the fixation of the networking module, so that the user can quickly remove the networking module for maintenance.
