Front-mounted lens online intelligent self-cleaning device and method based on lens fuzzy detection

Abstract

The invention provides a front-mounted lens online intelligent self-cleaning device based on lens fuzzy detection. A high-temperature industrial endoscope comprises an outer shell assembly and a lens assembly, the outer shell assembly comprises an outer shell, an inner shell and an image taking probe connected with the opening end of the outer shell, and the lens assembly comprises a front-mounted lens and multiple optical lenses, and a light through hole is formed in the top of the image taking probe. The online intelligent self-cleaning device comprises a lens fuzzy detection module and an intelligent cleaning assembly. The intelligent cleaning assembly is used for carrying out dust cleaning and air-cooling blow-drying on the front-mounted lens. The invention further provides a front-mounted lens online intelligent self-cleaning method based on lens fuzzy detection. According to the device and the method, fuzzy detection and intelligent cleaning to the front-mounted lens of the industrial endoscope can be realized, and the problems that in the prior art, fuzzy detection cannot be carried out on the lens, lens dust cannot be effectively removed, and the problem that the lens is gradually fuzzy cannot be solved are solved.

Description

technical field [0001] The invention relates to the technical field of industrial kiln equipment, in particular to an online intelligent self-cleaning device and method for the front lens of a high-temperature industrial endoscope based on lens blur detection. Background technique [0002] The lens blurring of industrial endoscopes is an urgent problem in the field of industrial kiln smelting; lens blurring can easily cause on-site misjudgment, cause on-site workers to operate incorrectly, and affect the smooth operation of industrial kilns; and lens blurring will gradually increase until It is completely impossible to capture images in the furnace and shorten the running time of the equipment; but this problem has always been unresolved. The reasons are mainly manifested in three aspects: 1. There is a lot of dust in the industrial furnace, and high-temperature dust is easy to adhere to the low-temperature lens to form scabs , so that the lens is blurred; 2. The airtight hi...

[0002] The lens blurring of industrial endoscopes is an urgent problem in the field of industrial kiln smelting; lens blurring can easily cause on-site misjudgment, cause on-site workers to operate incorrectly, and affect the smooth operation of industrial kilns; and lens blurring will gradually increase until It is completely impossible to capture images in the furnace and shorten the running time of the equipment; but this problem has always been unresolved. The reasons are mainly manifested in three aspects: 1. There is a lot of dust in the industrial furnace, and high-temperature dust is easy to adhere to the low-temperature lens to form scabs , so that the lens is blurred; 2. The airtight high pressure in the furnace causes the equipment to wear out due to the air flow; 3. The high temperature in the furnace makes it difficult for workers to enter the furnace to clean the equipment; to solve this problem, the following solutions are mainly adopted at home and abroad: 1. In the industry A solenoid valve is installed near the lens of the endoscope to scrape the dust on the lens to ensure a clear image, but the dust attached to the lens is solid and difficult to scrape off; 2. The industrial endoscope is automatically inserted into and withdrawn from the protection device, When it is detected that there is too much dust in the furnace, the lens withdraws from the peephole and closes the gate of the peephole to prevent the dust from touching the lens. There is a protective ring on the endoscope, and there is an air guide hole in the ring to connect with the fan. The airflow is ejected from the air guide hole to blow away the dust, but there will still be dust adhered to the lens, and the solid dust attached to the lens is difficult to blow off

[0003] Patent Publication No. CN210573003 utility model patent is an industrial endoscope with remote cleaning function. The endoscope lens is equipped with a probe at the lower end, and the upper end of the probe is fixedly connected with a spherical cover. The lens is located in the spherical cover. The lower end of the arc-shaped board is fixedly connected with a pair of sponge wipers, which can be operated remotely to wipe off the dust on the spherical cover, effectively ensuring the clarity of the captured image; Solid dust, and after cleaning the lens with a sponge, it will also be covered with dust, making it difficult to use for a long time

[0004] Patent Publication No. CN112444489 Patent Application for Invention is an endoscopic industrial furnace high-temperature industrial TV automatic extension and withdrawal protection device. The protective frame on the industrial TV is set on the outer wall of the industrial kiln observation port, and the upper part of the far observation port side is provided with a track. , there is an anti-collision plate on the outside of the control near the observation port, and the gate is set at the observation port; when the probe travels, the conical surface of the front end drives the anti-collision plate to move, the valve is opened, and the through hole of the sealing plate enters the furnace for observation, while When there is too much dust, the probe exits through the anti-collision plate and closes the gate to prevent dust from entering; when there is too much dust in the furnace, this device effectively prevents the dust from touching the industrial TV; but obviously after the probe exits, the screen in the industrial kiln It cannot be ingested, the monitoring time is shortened, and the dust will be adhered when the probe is extended into the through hole for observation, so the use value of this device is not high

[0005] Patent Publication No. CN211669443 utility model patent is an industrial endoscope that is easy to clean dust. The detection lens of the endoscope is provided with a protective ring, and an air guide hole is opened inside the ring wall of the protective ring. The inside of the air guide hole communicates with one end of the air guide tube. , the other end of the air guide pipe is connected with the fan, the inner wall of the protective ring is provided with an air guide ring, the outer wall of the ring is provided with a conduction hole communicating with the air guide hole, and the inside of the air guide ring is provided with a communication hole connected with the conduction hole; The device exhausts the gas through the communication hole, blows away the dust on the detection lens, and ensures that the detection lens can accurately observe the picture in the industrial kiln; however, although the exhaust gas can block most of the dust, there is still a small amount of dust that will adhere to the lens, and The dust attached to the lens is solid and difficult to be blown away, so this device cannot effectively remove the dust from the lens, and cannot solve the problem of gradual blurring of the lens
