Embodiment Construction

[0024] see figure 1 As shown, it is the cover plate door frame 1 in the intelligent explosion-proof and explosion-venting cover plate assembly of the present invention, that is, the cover plate 2 matched with the cover plate door frame. The cover plate 2 is provided with a symmetrically designed orifice 3, which acts as a pressure relief when the lower part of the cover plate 2 is impacted by a shock wave, and the symmetrical design makes the cover plate 2 evenly stressed, so as to resist more damage. Strong shock wave effect.

[0025] see figure 2 and image 3 Shown is the first embodiment of the converter plate in the present invention.

[0026] figure 2 and image 3 Among them, the cover plate assembly of the present invention is provided with a channel 4 located under the cover plate door frame 1, a conversion plate 5 located at the entrance and exit of the channel 4, and a monitoring control module; the monitoring control module includes an angle monitoring module,...

Abstract

The invention discloses an intelligent anti-explosion explosion-venting cover plate assembly used for pipe rack and considering civil defense design. An intelligent anti-explosion explosion-venting cover plate module for a feed port comprises a cover plate door frame module, a cover plate body module, a ventilating anti-explosion explosion-venting orifice module, a cover plate monitoring control module, and other modules; the ventilating anti-explosion explosion-venting orifice module can switch a cover plate among venting mode, anti-explosion mode and explosion-venting mode, corresponding to daily pipe rack ventilation, wartime pipe rack disaster-preventing (preventing external shock wave) and pipe rack internal relief passage (explosion-venting port) respectively, the cover plate monitoring control module provides recording and calculating, and analyzes the state of the anti-explosion explosion-venting cover plate. The cover plate monitoring control module includes a pressure monitoring module, an angle sensor and the like, is capable of judging working condition of the cover plate, an orifice and the like, and automatically, quickly and accurately detecting the properties of the intelligent anti-explosion explosion-venting cover plate online, subsequent regular maintenance is facilitated, and good operation state and protection are ensured.

Description

technical field [0001] The invention relates to the field of intelligent explosion-proof and explosion-venting cover plates and real-time detection of comprehensive utility corridors. Background technique [0002] As the underground blood of the city, the urban comprehensive pipe gallery is the lifeline for the transportation of water, electricity, natural gas and other materials. The comprehensive utility corridor itself has a source of danger. Under the current complex international situation, it is easy to become the focus of terrorist attacks and enemy air strikes in wartime. The feeding port (inspection well) is an important part of the mouth of the comprehensive pipeline corridor, and it is mainly used for pipeline entry corridors in normal times. Due to the large size of the feeding port (inspection well), the shock wave generated by the wartime explosion can easily enter the comprehensive pipe gallery, thereby causing damage to the lifeline project in the pipe galle...
