Description

Technical Field

[0001] This utility model relates to the field of steelmaking safety protection technology, specifically a steelmaking safety protection device. Background Technology

[0002] Steelmaking safety protection refers to the use of temperature sensors (such as furnace body, motor, pipeline, etc.) to collect temperature data in real time during the steelmaking process to prevent and control various safety risks such as high temperature, high pressure, molten metal splashing, gas leakage, dust explosion, and mechanical injury. Common types include thermocouples, resistance temperature detectors (RTDs), and infrared thermometers.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-3 As shown, this utility model provides a steelmaking safety protection device, including an adjusting frame 1, a lead screw 11 rotatably mounted inside the adjusting frame 1, a motor 12 mounted on one side of the upper surface of the adjusting frame 1, a guard plate 15 fixedly mounted on the upper surface of the adjusting frame 1, and the guard plate 15 being fixedly connected to the motor 12. The output end of the motor 12 passes through the adjusting frame 1 and is fixedly connected to the lead screw 11. A lifting block 13 is threaded onto the outer surface of the lead screw 11. A positioning post 14 is fixedly mounted inside the adjusting frame 1, and the positioning post 14 passes through the lifting block 13. The surface of the lifting block 13 is in contact with the inner wall of the adjustment frame 1. A mounting block 2 is fixedly provided on one side of the lifting block 13. Slider blocks 21 are symmetrically fixed on both sides of the mounting block 2. The sliders 21 are locked on one side of the adjustment frame 1. The sliders 21 on both sides of the mounting block 2 cooperate with the adjustment frame 1 to ensure that the component is installed stably and to avoid data acquisition deviation caused by vibration in the steelmaking environment. The lead screw 11 in the adjustment frame 1 is driven by the motor 12 to drive the lifting block 13 to move up and down along the positioning column 14, thereby adjusting the detection height of the probe 4 to adapt to different steelmaking equipment and working conditions.

[0020] A temperature prediction alarm component 3 is detachably connected to one side of the mounting block 2, and a probe 4 is fixedly installed on the lower surface of the temperature prediction alarm component 3. The temperature prediction alarm component 3 integrates an industrial-grade data processing chip and an XGBoost model. It collects data from the probe 4 through interfaces such as RS485, performs noise reduction processing, and makes real-time predictions. When the threshold is exceeded, it triggers an audible and visual alarm and links external devices. The probe 4 adopts types such as K-type thermocouples depending on the scenario. It is designed with high-temperature resistant ceramic encapsulation and quick-connect interface, which combines high-precision measurement and convenient maintenance capabilities. The two work together to realize intelligent monitoring and accurate early warning of steelmaking temperature. The temperature prediction alarm component 3 collects temperature data of key parts of steelmaking equipment in real time through the probe 4. At the same time, it combines other sensors (such as ambient temperature and humidity, equipment operating parameter sensors) to obtain multi-source data. The collected data is transmitted to the system backend through wired or wireless communication.

[0021] XGBoost, or eXtremeGradientBoosting, is an efficient implementation of the Gradient Boosting Decision Tree (GBDT) algorithm. It has strong learning capabilities and excellent generalization performance, can handle complex data relationships, and performs exceptionally well in prediction tasks across many fields.

[0022] The lower surface of the adjusting frame 1 is fixedly provided with a fixing member 5, and the upper surface of the fixing member 5 is provided with a through bolt groove. The fixing member 5 plays a key role in the installation and fixing of the steelmaking safety protection device. Its lower surface can be connected to a specific location in the steelmaking equipment or workshop. The through bolt groove on the upper surface makes it easy to fix the adjusting frame 1 firmly with bolts, ensuring that the entire device remains stable in harsh steelmaking environments such as high temperature and vibration, and avoiding the impact of loosening on the data acquisition and monitoring accuracy of the temperature prediction alarm component 3 and the probe 4.

[0023] A frame 24 is fixedly provided on one side of the upper surface of the temperature prediction alarm component 3, and the frame 24 is snapped onto one side of the upper surface of the mounting block 2. The frame 24 and the mounting block 2 are connected by bolts. A slot 23 is provided on one side of the mounting block 2, and an insert 22 is fixedly provided on one side of the temperature prediction alarm component 3, and the insert 22 is inserted into the slot 23. At the same time, since the temperature prediction alarm component 3 can be detached and installed through the engagement of the insert 22 with the slot 23 of the mounting block 2 and the bolt connection between the frame 24 and the mounting block 2, it is convenient for the maintenance and upgrading of the component and ensures the stability of the alarm function.

[0024] Working principle: The temperature prediction alarm component 3 collects temperature data of key parts of the steelmaking equipment in real time through the probe 4. At the same time, it combines other sensors (such as ambient temperature and humidity, equipment operating parameter sensors) to obtain multi-source data. The collected data is transmitted to the system backend through wired or wireless communication. The sliders 21 on both sides of the mounting block 2 cooperate with the adjustment frame 1 to ensure that the component is installed stably and avoids data acquisition deviation caused by vibration of the steelmaking environment. The lead screw 11 in the adjustment frame 1, driven by the motor 12, drives the lifting block 13 to move up and down along the positioning column 14, thereby adjusting the detection height of the probe 4 to adapt to different steelmaking equipment and working conditions.

[0025] The data transmitted to the backend is first cleaned to remove noise and outliers, and then transformed into a format suitable for XGBoost model processing through preprocessing methods such as normalization and feature encoding. Based on the XGBoost model trained on a large amount of pre-collected historical data, the real-time data is analyzed. Through a complex gradient boosting algorithm, the mapping relationship between temperature and other related factors is captured to predict the temperature change trend in the future.

[0026] When the temperature value predicted by the XGBoost model exceeds the preset threshold, the temperature prediction alarm component 3 immediately triggers the risk alarm mechanism. The alarm information is presented in various ways, such as displaying a conspicuous red warning message on the monitoring interface; notifying relevant personnel via SMS or email. At the same time, since the temperature prediction alarm component 3 can be detached and installed through the cooperation of the plug 22 with the slot 23 of the mounting block 2, and the bolt connection between the frame 24 and the mounting block 2, it is convenient for the maintenance and upgrading of the component and ensures the stability of the alarm function.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
