Description

Technical Field

[0001] This utility model relates to the field of furnace detection, and in particular to an adaptive cooling, visualized furnace thermal imaging intelligent monitoring system. Background Technology

[0002] Among the published patents, the furnace coking detection system (CN220932801 U) and the furnace flame monitoring device (CN215982664U) disclose different types of traditional furnace monitoring devices. While they can provide thermal imaging monitoring to some extent, their system cooling control only includes cooling gas pressure sensors or temperature sensors. When the temperature is too high or the cooling gas pressure is too low, the camera lens tube is automatically deactivated to provide protection. However, this cooling protection method cannot be automatically adjusted and is often subject to shutdowns due to unstable gas pressure, thus failing to guarantee long-term stable operation. Utility Model Content

[0009] Preferably, it also includes a gas source pressure transmitter and a flow sensor, which are installed in the cooling gas pipe between the cooling gas source and the mirror tube cooling protective cover.

[0010] Preferably, the forward and backward mechanism includes a drive motor, a conveyor chain, and a conveyor hoist.

[0011] Preferably, the temperature transmitter is located inside the cooling protective cover of the endoscope tube.

[0016] 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.

[0017] Example: Please refer to Figure 1 This utility model provides an adaptive cooling and visualized furnace thermal imaging intelligent monitoring system, including a camera tube system, a cooling gas source, and a flow regulating valve;

[0018] The camera tube system 2 includes an infrared thermal imaging camera 2.1, a tube cooling protective cover 2.2, a cooling air series duct 2.3, a lens group 2.4, a temperature transmitter 2.5, a gas source pressure transmitter, and a flow sensor;

[0019] The cooling air source is connected to the cooling air series pipe through the cooling air pipe, and the temperature transmitter is installed inside the mirror tube cooling protective cover;

[0020] It also includes a controller. When the camera tube system is inserted into the furnace for monitoring, the temperature transmitter collects the temperature inside the cooling protective cover of the tube. The controller adjusts the opening of the flow regulating valve in real time based on the temperature feedback from the temperature transmitter, thereby controlling the cooling air intensity.

[0021] It also includes a forward and backward mechanism, which consists of a housing 1.1, a drive motor 1.2, a conveyor chain 1.3, and a conveyor hoist 1.4.

[0022] After system startup, the air source pressure transmitter begins collecting cooling air pressure, and the high-precision temperature transmitter 2.5 begins collecting the temperature inside the lens tube cooling protective cover. This information is sent to the field controller 4 and then uploaded to the remote server for processing. The data acquisition module system determines whether each parameter is within the normal range. Once the startup conditions are met, the flow regulating valve opens (opening degree ≤ 10%), and the adaptive cooling unit begins operation. The forward / reverse actuator drive motor 1.2 starts, moving linearly via the conveyor chain 1.3 and the conveyor hoist 1.4, extending the camera lens tube system into the flue or furnace (e.g., ...). Figure 1 and Figure 2 The temperature transmitter 2.5 starts to monitor the working temperature of the camera tube in real time.

[0023] The controller determines the cooling airflow intensity based on temperature data and preset cooling strategies. Different temperature thresholds are set within the system, and corresponding cooling airflow intensities are preset for each temperature range. For example:

[0024] Low temperature zone: When the temperature is low, the flow regulating valve opening is automatically adjusted in the range of 11% to 30% to ensure that the temperature inside the lens tube cooling protective cover is ≤ the set value (e.g., 40℃) while keeping the cooling air intensity at the lowest level to save energy.

[0025] Medium temperature zone: When the temperature continues to rise to 50℃, the flow regulating valve increases its opening and automatically adjusts within the range of 31% to 60%. If the temperature drops below 40℃, the flow regulating valve increases its opening and adjusts down to the low temperature control zone.

[0026] High-temperature zone: When the temperature continues to rise to 60℃, it enters the high-temperature zone. The flow regulating valve increases its opening and automatically adjusts within the range of 61% to 100%. The cooling air intensity is at its maximum to protect the camera lens.

[0027] If the temperature drops to the previous temperature range, the valve opening will be adjusted accordingly to save energy. If the valve opening is at 100% and the temperature continues to rise to 70°C, the system will immediately alarm and the camera lens tube will be forcibly disengaged to protect the lens and camera.

[0028] The system employs closed-loop feedback control, adjusting the flow regulating valve opening based on real-time temperature feedback to control airflow and achieve stable adaptive performance. The system incorporates an air source pressure transmitter and flow sensor to monitor the cooling air velocity and pressure, ensuring that airflow and pressure reach the expected values. If insufficient cooling air or a temperature exceeding the preset upper limit is detected, the controller will issue an alarm signal or automatically take protective measures (such as shutting down the equipment or forcibly increasing cooling airflow).

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
