Description

Technical Field

[0001] The invention relates to the technical field of laboratory equipment, in particular to a laboratory operating table with a poisonous gas leakage protection function. Background Art

[0002] In modern laboratories, especially in the fields of chemistry, biology, and materials science (which may involve factories, pharmaceuticals, food processing, and other scenarios), a variety of toxic and harmful gases are often produced during the experiment. If these gases are not handled in time, they may accumulate around the laboratory table, posing a serious threat to the health and safety of the experimenters. Traditional laboratories usually rely on centralized ventilation systems or local exhaust devices to deal with these toxic gases. (Another scenario is basic and clinical toxicology research, such as carbon monoxide poisoning, hydrogen sulfide poisoning, ammonia poisoning, peripheral environment and cell experiments and animal experiments. The poisoning environment, that is, in high-risk work or experimental processes, is not entirely toxic gases generated by the experimental process.) However, these methods have the following problems:

[0003] Delayed response: Centralized ventilation systems can usually only provide uniform ventilation throughout the laboratory and cannot respond to local toxic gas leaks on the laboratory bench in a timely manner. When toxic gas leaks occur, they may have already caused harm to the experimenters, but the ventilation system has not yet been able to fully dilute or remove these harmful gases.

[0004] Monitoring blind spots: In some complex experimental environments, traditional ventilation and exhaust equipment is difficult to cover all possible toxic gas leakage points, and it is easy to form monitoring blind spots around the laboratory table. In this case, the local toxic gas concentration may exceed the safe range, and the experimenters cannot detect it in time.

[0005] No real-time risk assessment: Most existing laboratory safety equipment is limited to gas detection and alarm functions, and lacks comprehensive real-time risk assessment capabilities. During the experiment, the generation of toxic gases is uncertain and complex. Traditional equipment is difficult to accurately assess and predict the risk level of the experimental environment in the first place, resulting in the inability of experimenters to take effective preventive measures.

[0006] Insufficient system intelligence: With the development of laboratory technology, the experimental environment has become more and more complex, while traditional toxic gas treatment and monitoring equipment often lacks intelligent functions and cannot be flexibly adjusted according to the actual situation during the experiment, resulting in a significant reduction in the adaptability and effectiveness of the equipment.

[0007] In response to the above problems, there is an urgent need for a laboratory operating table system that can monitor the concentration of toxic gases in real time within the local area of ​​the laboratory table, conduct comprehensive risk assessment, and intelligently adjust the ventilation system to ensure the safety of the laboratory environment and the health of the experimenters.

[0008] The present invention proposes a laboratory operating table with a toxic gas leakage protection function, which aims to monitor the toxic gas concentration around the laboratory table in real time, conduct risk assessment and trigger an alarm by integrating a toxic gas sensor module, a data acquisition module, a central control system, an alarm module and a gas exhaust structure, and at the same time, it is linked with the laboratory ventilation system to achieve the purpose of efficiently treating harmful gases and preventing them from causing harm to experimental personnel and the experimental environment. The intelligent design and modular architecture of the system enable it to adapt to different types of experimental needs and provide a higher level of safety assurance. Summary of the invention

The left and right sides of the main experimental table 1 are respectively connected to a water tank 3 through an all-round telescopic rubber connecting sleeve 5, and a roller moving structure 2 is arranged at the bottom of the water tank 3 to facilitate the flexible movement and operation of the experimental table. A gas exhaust structure 4 is arranged on the upper part of the main experimental table 1, and the structure includes a protective net, an exhaust fan and a shell, wherein the exhaust fan is arranged in the inner cavity of the shell, and the protective net is arranged on the shell, which is used to exhaust the harmful gases generated during the experiment.

[0037] Example 2: Poison gas sensor module

[0038] The toxic gas sensor module is installed in the shell of the experimental bench to monitor the concentration of toxic gases inside the experimental bench and in the surrounding environment in real time. The sensor module is composed of various types of sensors, including infrared sensors, electrochemical sensors, etc. These sensors can detect a variety of harmful gases that may be produced in the experiment, such as hydrogen sulfide, sulfur dioxide, carbon monoxide, ozone, ammonia, methane, etc. The detection sensitivity and range of the sensor can be adjusted according to the experimental requirements to ensure accurate monitoring of different toxic gas concentrations.

[0039] Example 3: Toxic Gas Risk Prediction and Assessment System

[0040] The toxic gas risk assessment system is installed inside the main experimental table 1. The system includes a toxic gas sensor module, a data acquisition module, a central control system, an alarm module, and a display and recording module. The toxic gas sensor module monitors the toxic gas concentration around the experimental table in real time and transmits the data to the central control system through the data acquisition module. The data processing unit in the central control system processes the toxic gas concentration data and calculates the toxic gas risk index. The following formula is used for risk assessment:

[0041]

[0042] Among them, R is the toxic gas risk index, C i is the concentration of the ith poison gas, W i is the weight coefficient associated with the ith poison gas, V j is the evaluation value of other influencing factors (such as ventilation conditions, laboratory temperature, humidity, experiment type and duration, etc.), α and β are adjustment coefficients, the alarm module triggers an alarm when the toxic gas risk index calculated by the risk assessment unit exceeds a preset threshold, and the display and recording module is used to display the toxic gas concentration and risk index in real time, and archive the recorded data.

[0043] Example 4: Gas exhaust structure and ventilation system linkage

[0044] The gas exhaust structure 4 is linked with the laboratory's ventilation system. When the concentration of toxic gas increases during the experiment, it automatically increases the working intensity and speed of the ventilation system. The structure not only includes a protective net and an exhaust fan, but also integrates an intelligent control unit with adjustable air volume, which can adjust the exhaust volume according to real-time monitoring data, thereby effectively and quickly reducing the concentration of toxic gas.

The alarm system can be configured according to the specific situation of the laboratory and supports remote alarm and multi-user notification.

[0051] Example 7: Data recording and analysis function

[0052] The display and recording module displays the toxic gas concentration, risk index and predicted probability of toxic gas leakage in real time, and archives all monitoring data and evaluation results. The system has a long-term data storage function and can generate toxic gas concentration trend charts and risk assessment reports.

The mobile application also supports real-time alarm notification and data viewing, making it easy for managers to understand the safety status of the laboratory at any time.

[0057] Example 10: Backup power and continuous operation

[0058] To ensure that the system can still operate normally in the event of a power outage, the test bench is equipped with a backup power supply. This power supply can immediately switch and power the system when the main power is interrupted, ensuring the continuous operation of toxic gas monitoring, risk assessment and alarm functions. In addition, the system has fault detection and automatic recovery functions, and can automatically restart and resume normal working status after power is restored.

[0059] Example 11: Modular design and scalability

[0060] In order to meet the needs of different laboratories (or different scenarios), the present invention adopts a modular design, and each functional module can be configured and expanded according to actual needs. For example, sensor modules can be added to monitor more types of toxic gases, or the computing power of the central control system can be expanded to cope with more complex monitoring and evaluation tasks. The modular design makes the system highly scalable and adaptable, and is suitable for laboratories of different sizes and types.

[0061] Example 12: System maintenance and calibration

[0062] To ensure the long-term stability and accuracy of the system, the system has built-in sensor calibration and maintenance reminder mechanisms. Based on the usage and environmental conditions of the sensors, the system automatically generates calibration and maintenance reminders to guide the experimenter to calibrate regularly. In addition, the system also has a fault diagnosis function that can detect abnormalities in sensors or other components and provide detailed troubleshooting suggestions to ensure that the system is always in optimal working condition.

[0063] Example 13: Automatic generation of safety reports

[0064] The display and recording module can automatically generate safety reports. The system will automatically generate safety reports containing detailed analysis based on toxic gas monitoring data, risk assessment results and historical records. These reports are not only used for daily management, but also can provide important data support during laboratory safety audits or accident investigations.

[0065] Example 14: Emergency handling and automatic shutdown

[0066] In order to protect the experimenters and equipment in an emergency, the system is designed with an emergency shutdown function. When the system detects a high-risk toxic gas leak or other serious faults, it will automatically trigger the emergency shutdown procedure, shut down the experimental equipment and quickly start the ventilation system to minimize the risk and protect the safety of the experimenters.
