The utility model discloses a kind of coal mine water prevention and treatment water-filled channel building structure, including upside installation base, downside installation base, upside installation connecting piece, downside installation connecting piece and support rod;Second chute is opened on the downside installation base, first sliding block is slidably connected in the second chute, the first sliding block is fixedly connected with first ball joint by fixed rod;A kind of coal mine water prevention and treatment water-filled channel building structure, by the modularization design of above upside installation base and downside installation base as base frame unit module, single frame unit can be assembled in advance and then enter underground field splicing, without using integral pouring or welding and other complex process, greatly simplify underground construction process, reduce the complex operation in the limited space of underground, to effectively reduce construction operation difficulty and operation intensity.

The application discloses a highway construction safety intelligent monitoring and early warning system and method, which is integrated in a mobile working vehicle and comprises a support device, a double camera with night vision and zooming functions, a data processing device with an embedded Yolo-v5 improved algorithm model, an alarm device combining sound and light with vibration, and a power supply device. The camera is used for collecting video of a construction area in real time, the collected video is preprocessed through scene characteristic enhancement, a CSPDarknet53 backbone network with an introduced CBAM attention mechanism is used for identifying safety cones and construction personnel, a virtual boundary line is dynamically generated, the Euclidean distance of personnel to the boundary line is calculated, a multi-parameter weighted correction model is used for dynamically adjusting a safety threshold, and dangerous judgment is performed in combination with multi-frame fusion trajectory analysis and Kalman filter prediction. The application realizes all-weather accurate monitoring, dynamic boundary sensing, early warning and evidence reservation, and significantly improves the intelligent safety management level of highway construction.

The application relates to the technical field of waste gas treatment and purification equipment, and discloses a welding steel pipe welding waste gas unified collection treatment and purification device, which comprises a bottom plate, four groups of supporting legs are fixedly connected to the upper surface of the bottom plate, filter boxes are fixedly connected to the top ends of the supporting legs, a fan is fixedly connected to the middle of the upper surface of the bottom plate, an air suction pipe is connected to the input end of the fan, and a dust suction hood is connected to the bottom end of the air suction pipe. The welding steel pipe welding waste gas unified collection treatment and purification device is integrally designed through the parallel layout of double filter cavities, real-time monitoring of an air flow sensor, automatic linkage switching of a controller and a forward-reverse motor, when blockage or adsorption saturation occurs in one filter cavity, the air path can be automatically switched to the other filter cavity for continuous work, filter cores do not need to be replaced during the whole process, the problem that traditional single-cavity purification devices must interrupt production is solved, and the continuous operation efficiency of a welding production line and the automation and intelligent level of equipment are remarkably improved.
