Description

Technical Field

[0001] This invention relates to the field of thermal power plant power generation, specifically to a dual-source resin interface monitoring device based on gradient illumination. Background Technology

[0002] In condensate polishing systems of thermal power plants, resin separation towers are key equipment for separating and purifying water, and the height of the resin interface directly affects the efficiency and effectiveness of water treatment. Traditional methods for monitoring the resin interface mainly rely on visual observation or optical imaging-based equipment, but these methods often suffer from insufficient accuracy and significant monitoring difficulties.

[0003] In existing technologies, most common resin interface monitoring devices use single-point or surface light sources for illumination. This illumination method has the following shortcomings in practical applications:

[0004] Single-point light source issue: When using a single-point light source, the light spot may concentrate at the resin interface, resulting in a strong light spot phenomenon, which interferes with the accurate identification of the interface. In addition, due to the uneven distribution of light intensity, some areas of the resin interface may be overexposed or underexposed, affecting the monitoring accuracy.

[0005] Issues with surface light sources: While surface light sources can provide relatively uniform illumination, their brightness is often insufficient in workshop environments, especially under poor lighting conditions, making it difficult to ensure clear imaging of the resin interface. Furthermore, surface light sources cannot effectively eliminate stray reflections at the resin interface, resulting in blurred images.

[0006] Therefore, existing technologies still have significant limitations in improving the accuracy and reliability of resin interface monitoring. There is an urgent need for a new type of resin interface monitoring device to solve the above problems, especially to improve the stability and accuracy of interface identification.

[0008] A fixed bracket, installed on the resin separation tower connected to the condensate polishing system, is used to support the light source and the detection probe. It includes a first connector and a second connector. The first connector is connected to the bottom of the resin interface observation window and extends from the resin interface observation window to the ground to support the light source receiving platform. The second connector is connected to the light source receiving platform and extends vertically away from the ground to support the detection probe receiving platform.

[0009] The light source includes a first light source and a second light source.

The first angle is smaller than the second angle.

[0010] A detection probe is fixedly installed on the detection probe receiving platform, and the height of the resin interface is detected through the resin interface observation window.

[0011] The light source control system controls the light intensity of the first light source and the second light source, and controls the first light source to form direct light and the second light source to form diffused light.

[0012] Furthermore, both the first included angle and the second included angle are acute angles, and the first included angle is smaller than the second included angle.

[0019] Furthermore, the light source control system includes a PWM controller for independently adjusting the light intensity of the first light source and the second light source, wherein the PWM duty cycle of the first light source is set to be greater than the PWM duty cycle of the second light source.

[0020] Furthermore, the detection probe is connected to the data processing module to identify and record the resin interface height.

[0021] Furthermore, the data processing module processes the images acquired by the detection probe to eliminate light source interference and enhance interface contrast, thereby improving the accuracy of interface recognition.

[0029] The following will describe in detail, with reference to the accompanying drawings, a dual-source resin interface monitoring device based on gradient illumination according to the present invention.

[0030] like Figure 1The diagram shown is a structural schematic of a dual-source resin interface monitoring device based on gradient illumination according to this utility model.

[0031] Among them, 1 is the resin separation tower, 2 is the resin interface observation window, 3 is the first connector, 4 is the light source receiving platform, 5 is the second connector, 6 is the detection probe receiving platform, 7 is the detection probe, 8 is the first light source, and 9 is the second light source.

[0032] The fixed bracket is fixed on the resin separation tower 1 to support the entire monitoring device, including the light source and the detection probe 7. The fixed bracket includes a first connector 3 and a second connector 5. The head end of the first connector 3 is connected to the bottom end of the resin interface observation window 2 to ensure that the light source and the detection probe 7 can be installed without obstructing the resin interface observation window 2.

[0033] The first connector 3 extends from the direction away from the resin interface observation window (and parallel to the ground) and then from the direction closer to the ground (and perpendicular to the ground) to mount the light source receiving platform 4 (the platform is parallel to the ground), so that the light source can be mounted on the light source receiving platform 4.

[0034] The second connector 5 is connected to the light source receiving platform 4 at its head end, and is mounted on the detection probe receiving platform 6 (the platform is parallel to the ground) by extending along a vertical direction away from the ground, so that the detection probe 7 can be installed on the detection probe receiving platform 6.

[0035] The light source includes a first light source 8 and a second light source 9. The device has two light sources. The first light source 8 is installed on the left side of the light source receiving platform 4 (the viewing angle is to the left of the probe). The light from the first light source 8 forms a first angle with the vertical direction of the detection probe 7.

[0036] The second light source 9 is installed on the right side of the light source receiving platform 4 (the viewing angle is to the right of the probe). The light from the second light source 9 forms a second angle with the vertical direction of the detection probe 7.

[0037] Therefore, the first side is the left side of the viewing angle with the probe as the reference, and the second side is the right side of the viewing angle with the probe as the reference.

[0038] Both the first included angle and the second included angle are acute angles, and the first included angle is smaller than the second included angle.

[0039] Preferably, the first included angle is 35 degrees and the second included angle is 45 degrees. The first light source 8 (35 degrees) forms a reference illumination layer, providing near-vertical incident light to ensure basic interface brightness and reduce stray reflections. The second light source 9 (45 degrees) forms an enhanced illumination layer, providing lateral diffused light to enhance interface contrast and form a gradient transition zone.

[0040] The detection probe 7 is fixedly installed on the detection probe receiving platform 6 to ensure its stability, and the height of the resin interface is detected through the resin interface observation window 2.

[0041] The aforementioned detection device also includes a light source control system (not shown), which controls the light intensity of the first light source 8 and the second light source 9, and controls the first light source 8 to form direct light and the second light source 9 to form diffused light.

[0042] The brightness of the two light sources can be adjusted independently to ensure appropriate lighting effects.

[0043] Control the first light source 8 to form direct light, ensuring that the illumination is concentrated on the interface.

[0044] Control the second light source 9 to generate scattered light and avoid strong light spot phenomenon.

[0045] Furthermore, the distance between the first light source 8 and the second light source 9 is 150-200mm. The precise distance between the light sources can optimize the lighting effect and avoid interference or overlap.

[0046] Both the first light source 8 and the second light source 9 are LED light sources, and their light source parameters include: color temperature range of 4000K-6000K; color rendering index Ra≥80; luminous angle of 15-30 degrees; and luminous flux of 800-1200lm.

[0047] Both the first and second light sources are LED light sources: choosing LED light sources ensures high efficiency and long lifespan.

[0048] Color temperature range of 4000K-6000K: Select the appropriate color temperature range to ensure that the light source provides the appropriate lighting tone.

[0049] Color rendering index Ra≥80: Ensures that the light source has good color rendering properties and improves image quality.

[0050] The light emission angle is 15-30 degrees: Select an appropriate light emission angle to ensure that the light is focused on the resin interface area.

[0051] Luminous flux of 800-1200lm: The luminous flux range ensures that the brightness of the light source is appropriate, without being too dark or overexposed.

[0052] The light source control system includes a PWM controller for independently adjusting the light intensity of the first light source 8 and the second light source 9, wherein the PWM duty cycle of the first light source 8 is set to be greater than that of the second light source 9.

[0053] PWM controller: The PWM control system adjusts the brightness of the light source by adjusting the duty cycle to control the output intensity of the light source.

[0054] The PWM duty cycle of the first light source is set to be greater than that of the second light source: the light intensity of the first light source is stronger and the light intensity of the second light source is weaker, in order to control the distribution and pattern of illumination.

[0055] The detection probe 7 is connected to the data processing module (not shown) to identify and record the resin interface height for further analysis.

[0056] The data processing module processes the images acquired by the detection probe 7 using algorithms, removes interference from the light source, enhances the contrast between the interface and the background, and improves recognition accuracy.

[0057] The inspection probe includes an industrial camera to ensure high-quality image data for resin interface inspection.

[0058] In addition, laser scanners, infrared cameras, optical sensors, CCD cameras, or ultrasonic sensors can be added to provide different types of images or data depending on different needs and monitoring environments, in order to help effectively monitor resin interfaces.

[0059] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
