The invention discloses an elevator risk control safety management system and method based on the Internet of Things, and relates to the technical field of elevator safety risk control, and the elevator risk control safety management system comprises the steps of S1, data acquisition, S2, data transmission, S3, data processing, S4, model establishment, S5, foreign matter judgment, S6, countermeasures, S7, automatic measures, S8, self-calibration and S9, cyclic monitoring. The elevator shaft is scanned through the multiple three-dimensional laser scanning sensors to collect information, a model can be reconstructed in real time and compared with a standard model, foreign matter in the shaft can be found in time, potential risks such as collision and damage to safety parts caused by the foreign matter to elevator operation are effectively avoided, and elevator operation safety is guaranteed.

The utility model discloses a kind of self-filtering spray tower circulating water waste gas treatment systems, including tower body, circulating water pool, at least two layers of filler layer, spraying structure, microbubble generating unit, slag scraper and automatic slag discharge device, and the bottom of tower body is equipped with waste gas entrance, and the top of tower body is equipped with waste gas outlet, and tower body is equipped with circulating water pool;At least two layers of filler layer at least two layers of filler layer are vertically spaced and located in tower body: spraying structure includes multiple spraying heads evenly arranged above filler layer, and is communicated with circulating water pool by circulating pipeline;Microbubble generating unit is used to release microbubble to liquid layer of circulating water pool;Slag scraper is arranged at the liquid level of circulating water pool;Automatic slag discharge device is used to receive and handle the dross scraped by slag scraper.This application realizes the internal self-purification of spraying liquid, fundamentally solves the problem that traditional spray tower needs frequent water change due to water quality deterioration, achieves the goal of water-saving, energy-saving "zero water change".

The utility model provides a kind of valve walk and integrate device, comprising: rack; transmission unit, it is installed on rack, transmission unit includes screw rod, sliding seat, multiple sliding components and multiple rocker arms, sliding component includes slider and fixed part, fixed part is fixedly connected with sliding seat, slider can slide on fixed part, slider and rocker arm one-to-one correspondence, the free end of slider and rocker arm is hinged, and the fixed end of rocker arm is used to and is rotatably connected with the valve of installation on rack, sliding seat is equipped with the screw hole of cooperation with the screw thread of screw rod, when screw rod rotates, sliding seat can move along screw rod, to drive sliding component whole movement, to pull rocker arm rotation;Motor, it is used to drive screw rod rotation.The utility model can accurately control walk and integrate displacement, can satisfy the requirement of high-precision valve, simultaneously realize the walk and integration of multiple valves, improve walk and integration efficiency, reduce energy consumption, and can real-time monitoring walk and integration frequency.
