Description

Technical Field

[0001] This utility model belongs to the field of float glass technology, and in particular relates to a protective device for an endoscope lens in a float glass tin bath. Background Technology

[0002] In the float glass manufacturing industry, the tin bath is a core piece of equipment for producing high-quality glass, and precise monitoring of its internal environment is crucial for ensuring glass quality and improving production efficiency. The stability of the tin bath environment is directly related to the optical performance, flatness, and surface quality of the glass products. Therefore, real-time monitoring and rapid response to the internal state of the tin bath have become key technological requirements in the industry.

[0003] As a key tool for directly observing the dynamics inside the solder bath, the performance and reliability of the endoscope directly determine the accuracy of the observation data and the timeliness of the operational response. However, the high-temperature environment inside the solder bath poses a severe challenge to the normal operation of the endoscope. High temperatures can not only damage the optical components of the lens but also affect the stability of electronic components, leading to data distortion or equipment failure.

[0004] To address this issue, endoscope lens protection tubes were developed, becoming an indispensable part of the float glass production process. The main function of the protection tube is to provide a relatively stable low-temperature operating environment for the endoscope lens, ensuring its continuous and accurate operation in the high-temperature tin bath. Currently, the commonly used technical solution in the industry utilizes cooling water and nitrogen as protective media. Circulating cooling water removes heat, while nitrogen purges the endoscope lens, maintaining positive pressure in the lens area to prevent contaminants from entering, thus preventing lens blurring and reducing oxidation and corrosion.

[0005] However, this protection method, which relies on cooling water and nitrogen, has significant limitations. On the one hand, the continuous operation of the cooling system consumes a large amount of water and energy, increasing production costs. On the other hand, the stability of the nitrogen supply is crucial for production safety; any interruption in supply or pressure fluctuations will directly lead to an increase in the internal temperature of the protective tube, posing a risk of damage to the endoscope, and consequently affecting the continuous operation of the production line and the quality of glass products. Furthermore, the insufficient rapid response capability in emergency situations is also a problem that current protection technologies urgently need to address. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this invention is to provide a protective device for the endoscope lens in a float glass tin bath, which overcomes the problem of excessive reliance on protective gas and cooling water in existing endoscope lenses.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: An endoscope protection device for a float glass tin bath includes an endoscope tube, a water-cooled circulation assembly, an air-filling assembly, and a gas-cooling assembly, wherein an endoscope is disposed inside the endoscope tube; The endoscope tube is provided with an observation hole at one end near the inside of the tin bath, and the endoscope lens is positioned to be aligned with the observation hole; The endoscope is provided with a cooling channel, and the water-cooled circulation assembly is connected to the cooling channel for circulating cooling water into the cooling channel. The inflation assembly is sequentially connected to the gas cooling assembly and the inside of the endoscope. The inflation assembly is used to provide protective gas. The protective gas is cooled by the gas cooling assembly and then introduced into the inside of the endoscope, and finally blown out from the observation hole.

[0008] According to one embodiment of the present invention, a protective shell is provided at the end of the endoscope tube away from the endoscope lens.

[0009] According to one embodiment of the present invention, a mounting block is provided on the protective shell for connecting with the wall of the tin bath.

[0010] According to one embodiment of the present invention, a signal line is included, which is disposed inside the endoscope tube and connected to the endoscope lens. The signal line extends into the protective shell and passes through the protective shell.

[0011] According to one embodiment of the present invention, the water-cooled circulation assembly is connected to the inlet of the cooling channel via an inlet pipe and to the outlet of the cooling channel via a return pipe.

[0012] According to one embodiment of the present invention, the gas cooling component is connected to the interior of the endoscope through an air inlet pipe.

[0013] According to one embodiment of the present invention, the protective gas is nitrogen.

[0014] According to one embodiment of the present invention, the gas cooling component is a vortex cooler.

[0015] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art: This invention utilizes nitrogen gas to purge the endoscope lens, effectively preventing dust accumulation on its surface, ensuring lens cleanliness, and avoiding the impact of dust buildup on image clarity, thereby guaranteeing accurate monitoring of the internal environment of the solder bath. Since the endoscope lens is close to the inside of the solder bath and experiences high temperatures, nitrogen purging creates an airflow barrier at the lens, achieving initial heat insulation and cooling, reducing the impact of high temperatures on the lens, and extending its service life.

[0016] Nitrogen gas is cooled by a vortex cooler, enabling it to cool the interior of the endoscope tube, especially the endoscope lens. The cooled nitrogen further reduces the temperature at the endoscope lens, effectively coping with high-temperature environments and ensuring the lens operates at a suitable temperature, thus improving its stability and reliability.

[0017] After installing a vortex cooler, the cooled nitrogen gas, combined with the water-cooled circulation components, can reduce nitrogen consumption, lower operating costs, and improve resource utilization efficiency while ensuring cooling effect.

[0018] In the event of an emergency water supply interruption, this device can continuously protect the endoscope for a certain period of time. The cooled nitrogen gas can still provide some cooling effect, preventing damage to the endoscope from a rapid temperature rise due to a sudden water supply interruption, thus ensuring safe production and equipment protection.

[0019] Therefore, this invention overcomes the problem of excessive reliance on nitrogen and cooling water in existing endoscope protection devices, reduces the risk of damage to the endoscope due to interruption of nitrogen or cooling water supply, and improves the independence and stability of the device. It can effectively protect the endoscope in emergency situations of water or gas outages, improving the endoscope's susceptibility to damage in emergency conditions, ensuring uninterrupted monitoring of the solder bath's internal environment, greatly enhancing the monitoring level of the solder bath's internal environment, and providing strong support for the stable operation of the production process.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] See Figure 1 The core of this utility model is to provide a protective device for the endoscope lens in the tin bath of float glass, including an endoscope tube 1, a water-cooled circulation assembly, an air-filling assembly and a gas-cooling assembly, with an endoscope lens 2 installed inside the endoscope tube 1.

[0025] An observation hole is provided at one end of the endoscope tube 1 near the inside of the tin bath. The endoscope lens 2 is aligned with the observation hole and fixed. The endoscope lens 2 is controlled by the on-site control box and simultaneously transmitted to the control panel in the central control room for remote control. The angle of the monitoring screen in the central control room is adjusted by rotating the endoscope lens 2.

[0026] The endoscope tube 1 has a cooling channel, and a water-cooling circulation assembly is connected to the cooling channel to circulate cooling water into it. An inflation assembly is sequentially connected to the gas cooling assembly and the interior of the endoscope tube 1. The inflation assembly provides a protective gas, which is cooled by the gas cooling assembly before being introduced into the endoscope tube 1 and finally blown out through the observation port. In this embodiment, the protective gas is nitrogen, and the gas cooling assembly is a vortex cooler 6.

[0027] It also includes a protective shell 3, located at the end of the endoscope tube 1 away from the endoscope lens 2. It also includes a mounting block 4, located on the protective shell 3, for connecting to the wall of the tin bath.

[0028] It includes a signal line 5, which is located inside the endoscope tube 1 and connected to the endoscope lens 2. The signal line 5 extends into the protective shell 3 and passes through the protective shell 3 to connect to the central control box.

[0029] The water-cooled circulation assembly is specifically connected to the inlet of the cooling channel via the water inlet pipe 8 and to the outlet of the cooling channel via the water return pipe. The gas-cooled assembly is internally connected to the endoscope tube 1 via the air inlet pipe 7.

[0030] This invention utilizes nitrogen gas to purge the endoscope lens 2, effectively preventing dust accumulation on its surface, ensuring lens cleanliness, and avoiding the impact of dust buildup on the image clarity of the endoscope lens 2, thereby ensuring accurate monitoring of the internal environment of the solder bath. Since the endoscope lens 2 is close to the inside of the solder bath and experiences high temperatures, nitrogen purging creates an airflow barrier at the endoscope lens 2, achieving preliminary heat insulation and cooling, reducing the impact of high temperatures on the lens, and extending the lens's lifespan.

[0031] The nitrogen gas is cooled by the vortex cooler 6, which enables the nitrogen to cool the inside of the endoscope tube 1, especially the endoscope lens 2. The cooled nitrogen gas can further reduce the temperature of the endoscope lens 2, effectively cope with high-temperature environments, ensure that the lens operates at a suitable temperature, and improve the stability and reliability of the lens.

[0032] After installing the vortex cooler 6, the cooled nitrogen gas, combined with the water-cooled circulation components, can reduce the amount of nitrogen used, lower operating costs, and improve resource utilization efficiency while ensuring the cooling effect.

[0033] In the event of an emergency water supply interruption, this device can continuously protect the endoscope 2 for a certain period of time. The cooled nitrogen gas can still provide a certain cooling effect, preventing damage to the endoscope 2 due to a sudden increase in temperature caused by the sudden water interruption, thus achieving safe production and equipment protection.

[0034] Therefore, this invention overcomes the problem of excessive reliance on nitrogen and cooling water in existing endoscope lens 2 protection devices, reduces the risk of damage to the endoscope lens 2 due to interruption of nitrogen or cooling water supply, and improves the independence and stability of the device. It can effectively protect the endoscope lens 2 in emergency situations of water or gas outages, improving the endoscope lens 2's susceptibility to damage in emergency situations, ensuring uninterrupted monitoring of the solder bath's internal environment, greatly improving the monitoring level of the solder bath's internal environment, and providing strong support for the stable operation of the production process.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
