Intelligent anti-clogging integral safety shaft

Abstract

The invention discloses an intelligent anti-clogging integral safety shaft. The safety shaft comprises a shaft cover, a cylindrical shaft body, an internal frame, a crushing type grille device and a PLC (programmable logic controller) system, wherein the internal frame comprises a blocking net frame, a ladder and a bottom plate; a water inlet and a water outlet are formed in the side wall of the shaft body, sewage enters from the water inlet, solid impurities contained in the sewage are crushed into fine particles by the crushing type grille device, and the fine particles are discharged from the water outlet; the PLC system comprises a PLC, a liquid level sensor and a display screen, the crushing type grille device and the liquid level sensor are electrically connected with the PLC, and the PLC and the display screen are located in a cabinet at the top of the side wall of the cylindrical shaft body. The safety shaft has the advantages that the quality is stable, the construction period is short, the shaft body is resistant to corrosion, acid-base and ageing, the own weight is low, the impact resistance is high, transportation and mounting are convenient, and by means of the PLC system, automatic sewage discharge,, automatic liquid level detection as well as intelligent monitoring and control can be realized.

Description

technical field [0001] The invention belongs to the field of municipal engineering, in particular to an intelligent anti-clogging integrated safety well. Background technique [0002] The safety well is the connecting pipe fitting on the drainage pipeline. It is a vertical shaft built at a certain distance on the position of the bottom pipeline. It is mainly used for maintenance of pipelines, sludge removal and connection of pipelines in different directions and heights. Specifically, there are safety wells for flushing, Street safety wells, water diversion safety wells, sewage safety wells, etc. Safety wells are generally located at the intersections and turns of drainage pipes. Usually, these intersections and turns are also places where garbage is easy to clog. In order to prevent garbage from clogging drainage pipes, the existing Safety wells often weld metal grids or screens at the sewage inlet and fix them on the frame to form fixed grids and screens to intercept solid...

[0002] The safety well is the connecting pipe fitting on the drainage pipeline. It is a vertical shaft built at a certain distance on the position of the bottom pipeline. It is mainly used for maintenance of pipelines, sludge removal and connection of pipelines in different directions and heights. Specifically, there are safety wells for flushing, Street safety wells, water diversion safety wells, sewage safety wells, etc. Safety wells are generally located at the intersections and turns of drainage pipes. Usually, these intersections and turns are also places where garbage is easy to clog. In order to prevent garbage from clogging drainage pipes, the existing Safety wells often weld metal grids or screens at the sewage inlet and fix them on the frame to form fixed grids and screens to intercept solid impurities in sewage. Usually, some solid impurities will accumulate on the grids and screens after a period of time The amount of sewage passing through is reduced or completely blocked. Patent CN202450613U discloses an anti-clogging precast concrete inspection well. A screen is provided on the water outlet pipe to prevent clogging. The anti-clogging precast concrete safety well is poured with concrete. The construction period is long, the impact on the environment and urban traffic is great, and the quality stability is poor; after the safety well is used, it is necessary to regularly inspect, repair, dredge and make statistics on the internal conditions of the safety well. Usually, maintenance personnel jump into the safety well , the maintenance personnel are easily injured, there are potential safety hazards, or the maintenance personnel are tied with a rope, and then slowly climbed in, which increases the labor intensity of the maintenance personnel. Enter the safety well for inspection and maintenance, but because the safety well has been buried underground for a long time, it is not clear whether the air composition in the well is harmful to the body, whether there is any leakage, etc. If you go down the well blindly, it will pose a great threat to the personal safety of the people who go down
