Integrated explosion-proof network intelligent manhole cover

Abstract

The invention discloses an integrated anti-explosion networked intelligent inspection well lid. The integrated anti-explosion networked intelligent inspection well lid comprises an explosion-proof box arranged below an inspection well lid body; the explosion-proof box and the inspection well lid body are fixed in a sealed mode to form a sealed cavity; a lithium battery, a Hall liquid level switch, a gyroscope position sensor, a gas sensor, a microprogrammed control unit (MCU) processor and wireless communication modules which includes a global position system (GPS) / Beidou positioning module and a code division multiple access (CDMA) / general packet radio service (GPRS) communication module and is connected with the MCU processor are arranged inside the explosion-proof box. Multiple solar panels are evenly arranged on the upper plane of the inspection well lid body in the circumference. The gas sensor is arranged at the bottom of the explosion-proof box. A floater moves up and down through a guide rod arranged at the bottom of the explosion-proof box and is provided with a rubber film and a magnet. When the position, liquid level and gas sensors send signals, the MCU processor sends three different position, liquid level and gas signals through the CDMA / GPRS communication module, and if the water level is high, the rubber film of the floater is automatically embedded into the groove above and prevents water from entering a gas detection probe to achieve the protection function. The integrated anti-explosion networked intelligent inspection well lid is novel in structural design, high in gas detection sensitivity, explosion proof overall, and good in waterproof safety.

Description

technical field [0001] The invention relates to the application of solar energy and lithium batteries, and industrial safety explosion-proof technology, more specifically, an integrated explosion-proof networked intelligent manhole cover. Background technique [0002] The valve well of the urban gas system is one of the important facilities in the gas pipeline network. Various valves and expansion joints in the gas pipeline network are mainly arranged in the valve well. The space in the valve well is generally narrow and the airtight space is good. After long-term operation of the pipeline network facilities, in a humid environment, local gas leakage will occur on the valve body, flange and other parts due to corrosion, expansion and contraction, etc., which may easily cause gas accumulation. In addition, when the gas pipeline near the valve well transmits leakage, it will also spread to the valve well to generate accumulation. When the gas accumulates to a certain amount a...

Problems solved by technology

[0004] The purpose of the present invention is to propose an integrated explosion-proof network intelligent manhole cover. Since natural gas is lighter than air, it will accumulate upward after leakage. The present invention combines solar power supply technology, wireless transmission technology, low power consumption control, and waterproof protection system , anti-theft GPS / Beidou positioning tracking, CDMA / GPRS communication module and gas leakage detection technology are combined and integrated into the manhole cover to solve the problem that the gas detector cannot be monitored in real time, the gas detection sensitivity is not high, and the waterproof safety is not high enough in the existing technology and easy to be stolen
