The invention relates to an artificial intelligence range hood which can quickly and conveniently discharge oil smoke and indoor polluted air by selectively opening or closing a movable air inlet and outlet pipeline or an indoor polluted air inlet and outlet pipeline. The present invention can prevent occupational diseases such as lung cancer caused by continuously inhaling oil fume containing a plurality of harmful substances in an amount equal to or greater than a reference amount in advance, thereby significantly improving the indoor air quality and automatically creating a comfortable and clean air environment, and can reduce the amount of oil fume generated by lowering the movable intake / exhaust duct to a position where the oil fume is generated. The oil fume can be rapidly sucked and discharged, and after being sucked into the oil fume suction inlet from the side face of the oil collecting disc in the 360-degree direction, the oil fume is rapidly discharged through the movable air inlet and outlet pipeline and the fixed air inlet and outlet pipeline in sequence, so that the health of cooks is effectively protected.

The invention discloses a portable occupational disease hazard factor detector and a detection method, and relates to the technical field of detection devices.The portable occupational disease hazard factor detector comprises a rack, and a detection channel is formed in the rack; a first absorption part and a second absorption part are arranged in the detection channel, the first absorption part is used for absorbing dust, and the second absorption part is used for absorbing chemical substances to be detected; a pneumatic part is arranged on the rack, and is used for enabling gas to flow into the detection channel and sequentially pass through the first absorption part and the second absorption part. The occupational disease hazard factor detection method has the advantage that detection personnel can conveniently detect occupational disease hazard factors.

The invention relates to the technical field of occupational health, in particular to a big data quantification-driven occupational disease hazard factor evaluation and prevention and treatment system, which comprises a data optimization processing module, a data feature acquisition module, an occupational disease index evaluation module and an occupational disease early warning and prevention and treatment module, outputting the reconstructed phase space matrix and data information corresponding to different time points; the data feature obtaining module obtains feature information and a classification result of occupational health data for the reconstructed phase space matrix and the data information by using a feature learning network model; the occupational disease index evaluation module determines weights of different occupational disease indexes based on the feature information and the classification result, and analyzes a comprehensive hazard index of the occupational disease indexes in combination with a hazard index level evaluation model; and the occupational disease early warning and prevention module sends an occupational disease early warning signal based on the comprehensive hazard index and matches a prevention scheme. The modules work cooperatively to achieve occupational disease evaluation and prevention and control, and the prevention and control efficiency and effect are improved.

The present application provides a chiseling device suitable for dense steel bars and narrow clearance, which is detachably fixed on the steel bars of the extension of the existing structure to realize the chiseling work on the chiseling surface of the existing structure; the chiseling device comprises a main frame, two symmetrical clamping mechanisms arranged on the main frame, and a chiseling mechanism between the two clamping mechanisms, wherein the two clamping mechanisms are clamped on the corresponding two steel bars respectively, and the chiseling mechanism is used for performing specific chiseling work. By configuring double clamping mechanisms on the main frame, the device can be directly and detachably anchored on the exposed steel bars of the existing structure, so that the device can flexibly work in the dense steel bar gap that cannot be reached by conventional equipment, effectively eliminating the construction blind area under complex working conditions; the installation stability and stress balance in the narrow space are ensured, the chiseling reaction force is directly borne by the frame and the steel bars, the direct harm of vibration to the human body is avoided, and the risk of occupational disease is significantly reduced.

The utility model relates to an unmanned operation control system of a discharging car, and relates to the technical field of aluminum oxide production, and the unmanned operation control system comprises a wireless network device which covers an operation area through a wireless network; the real-time position distance between the discharging trolley and the target grinding head stock bin is positioned through a positioning device; the height of the mineral aggregate in the bin grid is monitored through the material level monitoring device; and the center console controls the unloading vehicle to move to the real-time position distance, and the ore raw materials transported by the unloading vehicle are unloaded into the bin cells till the height of the ore materials is equal to the preset height of the ore materials. According to the scheme, an operator does not need to go to the site personally and only needs to remotely control the discharging car at the center console, direct exposure in a high-dust environment is avoided, the risk of suffering from occupational diseases such as pneumoconiosis is reduced, interference of steam and dust in a high-humidity environment is avoided, position information of the discharging car can be accurately obtained, and the working efficiency is improved. Positioning deviation caused by visual interference is avoided, and material leakage or blockage accidents are avoided.
