Description

Technical Field

[0001] This utility model belongs to the field of gas sensor technology, specifically relating to an explosion-proof gas sensor with a high-temperature resistant structure. Background Technology

[0002] With the continuous advancement of industrialization, various gas sensors are widely used in industries such as petrochemicals, mining, and environmental monitoring to detect the concentration and composition of gases, promptly identify leaks of harmful gases or other anomalies, and ensure production and personal safety. The stability and accuracy of gas sensors have a crucial impact on their application effectiveness. Therefore, researchers and engineers have been committed to improving the reliability of sensors, especially in applications under high temperature, high pressure, and harsh environments.

[0003] However, traditional gas sensors operating in high-temperature environments are often affected by external or internal temperature fluctuations, leading to decreased detection accuracy or even malfunction. The sensing elements and circuitry within gas sensors are easily damaged in environments with large temperature fluctuations, causing false alarms or missed alarms, thus affecting the accuracy and timeliness of gas detection. Therefore, effectively controlling the operating temperature of sensors and avoiding the negative effects of high temperatures has become one of the urgent problems to be solved in gas sensor technology.

[0004] Existing gas sensors (publication number: CN214845074U) have the following drawbacks in terms of explosion-proof gas sensors:

[0005] 1. Unstable operation in high-temperature environments: Traditional gas sensors exhibit poor stability under high-temperature conditions. Because the sensitive elements and circuitry within gas sensors are highly sensitive to temperature changes, increases in external or internal temperatures often lead to a decrease in sensor accuracy. Especially in industrial settings, gas sensors are frequently exposed to high temperatures, which can cause sensor malfunctions, inaccurate results, and even data distortion. Therefore, there is an urgent need for an explosion-proof gas sensor with a high-temperature resistant structure.

[0006] 2. Lack of Intelligent Alarm Function: While many current gas sensors possess basic alarm functions, these functions are often limited to localized sound or display, failing to quickly notify personnel and provide real-time remote monitoring data when sensor anomalies occur. Furthermore, most existing gas sensors lack remote data transmission modules, preventing real-time uploading of detection data to the monitoring system. This results in personnel being unable to promptly obtain sensor operating status and data fluctuations, missing optimal intervention opportunities. Therefore, there is an urgent need for an explosion-proof gas sensor with intelligent alarm functionality. Utility Model Content

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an explosion-proof gas sensor with a high-temperature resistant structure, comprising a sensor body, a data cable, and a coolant storage tank. The coolant storage tank is provided on the front of the sensor body, and a fixing plate is provided on the back of the sensor body. A gas inlet is provided on the upper left side of the sensor body, and a gas outlet is provided on the upper right side of the sensor body.

A battery pack is provided at the lower end of the remote data transmission module, and the probe of the gas detection module extends into the gas flow channel.

[0009] The coolant storage tank has a coolant inlet at the top and a coolant outlet at the bottom. The coolant inlet and outlet are connected to a coolant delivery pipe to ensure the temperature inside the coolant storage tank.

[0010] Furthermore, the fixing plate is provided with bolt holes.

[0011] Furthermore, the gas detection module transmits the detected data to the data processing module via a data cable.

[0012] Furthermore, the data processing module controls the buzzer alarm via a data cable, and transmits the detected data to the remote data transmission module via the data cable, which then uploads the detected data.

[0013] Furthermore, the battery pack supplies power to the data processing module via a data cable.

[0014] This utility model has the following beneficial effects:

[0015] 1. This device incorporates a coolant storage tank within its outer casing. This tank stores coolant, absorbs heat generated within the sensor, and insulates against external high temperatures. Coolant inlet and outlet ports are located at the top and bottom of the storage tank, connecting to a coolant transport pipeline. This ensures the coolant within the storage tank maintains a relatively stable temperature, offering the following benefits: Effective temperature control design: By incorporating a coolant storage tank within the casing, this device stores coolant, absorbs heat generated within the sensor, and effectively insulates against external high temperatures affecting the internal sensor components. This cooling solution ensures the sensor maintains a stable operating temperature even in high-temperature environments, improving the reliability of the equipment.

[0016] 2. This device features a buzzer alarm on the side of the sensor body.

[0029] In this embodiment, the fixing plate 3 is provided with bolt holes.

[0030] In this embodiment, the gas detection module 9 transmits the detected data to the data processing module 10 via the data line 13.

[0031] In this embodiment, the data processing module 10 controls the buzzer alarm 5 through the data cable 13, and the data processing module 10 transmits the detected data to the remote data transmission module 11 through the data cable 13. The remote data transmission module 11 then uploads the detected data.

[0032] In this embodiment, the battery pack 12 supplies power to the data processing module 10 via the data line 13.

[0033] This embodiment discloses an explosion-proof gas sensor with a high-temperature resistant structure, which includes several key components to ensure its stability, data monitoring accuracy and safety in high-temperature environments.

[0034] Sensor Body: The sensor body is the core of the entire device, housing all functional components. A coolant reservoir is located on the front of the sensor body to store coolant and absorb heat generated inside the sensor. A mounting plate is located on the back to securely install the sensor body in the appropriate position, ensuring stable sensor operation.

[0035] Coolant reservoir: Located on the front of the sensor body, the coolant reservoir stores coolant and absorbs internal heat through its flow, isolating the sensor from external high temperatures. Coolant inlet and outlet ports are located at the top and bottom of the reservoir, connecting to coolant delivery pipes to ensure continuous coolant flow, maintain a stable temperature, and prevent sensor performance degradation or malfunction due to overheating.

[0036] Gas inlet and outlet: A gas inlet is located on the upper left side of the sensor body, through which gas enters the sensor for detection; while a gas outlet is located on the upper right side, expelling gas from the sensor. A buzzer alarm is installed below the outlet. When the gas sensor detects abnormal data fluctuations, the buzzer will sound an alarm to alert nearby personnel, ensuring timely response.

[0037] Buzzer Alarm: The buzzer alarm is installed at the lower end of the gas outlet. When the sensor detects abnormal fluctuations, the data processing module will control the buzzer alarm to sound. This design allows on-site personnel to immediately recognize potential equipment problems and take appropriate measures to address them.

[0038] Data Processing Module: Connected to the gas detection module, the data processing module is responsible for processing and analyzing the data collected by the sensors. If the sensor data is abnormal, the data processing module will trigger the alarm system. Connected to a buzzer alarm, the data processing module can effectively issue an alert. Furthermore, the data processing module also transmits the detected data to the remote transmission module for real-time uploading.

[0039] Gas detection module: The gas detection module inserts its probe into the gas flow channel to detect the gas entering the sensor. The module's upper end connects to the data processing module via a data cable, transmitting the real-time monitored gas data to the data processing module for processing and analysis.

[0040] Remote data transmission module: This module uploads processed gas data to a remote system, allowing staff to remotely view the data and monitor equipment status. This feature significantly improves the real-time performance and management efficiency of gas detection.

[0041] Battery Pack: The battery pack provides power to the entire system, supporting the normal operation of the data processing module and all other components. The battery pack supplies power to the data processing module via data cables, ensuring the reliability of the equipment during long-term operation.

[0042] Component Coordination Logic: Coolant System: During sensor operation, heat is generated inside the sensor. This heat is absorbed by the coolant in the coolant reservoir. The coolant enters the reservoir through the inlet and exits through the outlet, forming a circulation flow to ensure a stable coolant temperature. This coolant flow not only helps regulate the internal temperature but also effectively insulates against the effects of external high temperatures, allowing the sensor to operate stably even in high-temperature environments.

[0043] Gas detection and data processing: Gas enters the gas flow channel of the sensor body through the gas inlet, and the probe of the gas detection module monitors the gas in real time. When the sensor detects abnormal data, the data processing module reacts immediately. If the gas concentration exceeds the standard or other detection data is abnormal, the data processing module will control the buzzer to sound an alarm, alerting the staff. Simultaneously, abnormal data is uploaded in real time to the remote monitoring system via the remote data transmission module, ensuring that staff receive alarm information promptly.

[0044] Battery power: The battery pack provides power to the entire system via the data cable, supporting the stable operation of the data processing module and other components. The battery pack is designed to ensure that the device can operate for extended periods without an external power source, adapting to various application scenarios.

[0045] In high-temperature environments, the coolant circulates continuously, absorbing internal heat and preventing external high temperatures from affecting the sensor's operation.

[0046] After the gas enters the sensor, the gas detection module will detect its concentration in real time and transmit the data to the data processing module.

[0047] The data processing module analyzes and processes the detection data. If an anomaly is detected, it immediately triggers a buzzer alarm and uploads the data to the remote monitoring platform to ensure that staff can promptly detect and address the problem.

[0048] The battery pack provides continuous power to the entire system, ensuring the reliability of the equipment during continuous operation.

[0049] This structural design, through the coordinated operation of various components, not only improves the working stability of the sensor, but also enhances its safety and intelligence, enabling it to meet the needs of gas detection in complex, high-temperature environments.
