Inclined manhole cover alarm system and alarm method

Abstract

The invention relates to an inclined well lid alarm system and an alarm method. The inclined well lid alarm system comprises a well lid seat ring, an outer cover for sealing the well lid seat ring is arranged on the upper portion of the well lid seat ring, an inner cover is arranged in the well lid seat ring, the inner cover is provided with a groove for containing a sealed waterproof box, at least two symmetric glass containers are obliquely arranged in the sealed waterproof box, and mercury switches for detecting inclination of the inner cover are arranged in the glass containers. A circuit board is arranged in the sealed waterproof box, and provided with an MCU, a power module, a communication module and a driving module, the power module, the communication module and the driving module are connected with the MCU, and the driving module is used for driving the mercury switches. The inclined well lid alarm system is simple in circuit function, when a well lid is opened, long conductors and short conductors are connected through sliding of mercury in the mercury switches, and therefore a well lid opening alarm is given out.

Description

technical field [0001] The invention relates to an alarm system and an alarm method for an inclined manhole cover. Background technique [0002] The well cover is the closure on the top of the entrance and exit leading to the underground facilities. It is necessary to install the well cover in all places where public facilities such as running water, telecommunications, electricity, gas, heating, fire protection, and sanitation are installed. With the rapid development of my country's economy, my country's infrastructure construction has ushered in a new cycle, and the market demand for manhole covers in urban planning and road construction is huge. However, manhole covers are rolled and damaged from time to time, resulting in a decrease in the safety of roads and facilities. [0003] Manhole covers in the road are mainly used to cover the deep wells on the road. According to the different underground pipelines, some deep wells are used as water pipelines, line pipelines or...

However, manhole covers are often crushed and damaged, which reduces the safety of roads and facilities

[0003] Manhole covers in the road are mainly used to cover the deep wells on the road. According to the different underground pipelines, some deep wells are used as water pipelines, line pipelines or gas pipelines. The setting of deep wells is conducive to the maintenance of pipelines. However, in some special cases Under heavy rain or human factors, the manhole cover is removed and people or objects fall into the deep well, or are jacked up by the impact of the internal pressure of the deep well. These phenomena will bring huge safety hazards to people's travel.

At the same time, when the manhole cover is used as a cable and line pipeline, criminals often steal the cable by removing the manhole cover, which brings losses to national property.

[0004] The traditional manhole cover is a single-layer structure, which is easy to be damaged by rolling, and the manhole cover opening alarm is mostly electromagnetic induction to alarm, so there is an urgent need for a more stable manhole cover structure and a manhole cover that matches the manhole cover structure.
